-Ruby is copyrighted free software by Yukihiro Matsumoto <matz@netlab.jp>.
-You can redistribute it and/or modify it under either the terms of the GPL
-(see the file GPL), or the conditions below:
+		    GNU GENERAL PUBLIC LICENSE
+		     Version 1, February 1989
 
-  1. You may make and give away verbatim copies of the source form of the
-     software without restriction, provided that you duplicate all of the
-     original copyright notices and associated disclaimers.
+ Copyright (C) 1989 Free Software Foundation, Inc.
+                    675 Mass Ave, Cambridge, MA 02139, USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
 
-  2. You may modify your copy of the software in any way, provided that
-     you do at least ONE of the following:
+			    Preamble
 
-       a) place your modifications in the Public Domain or otherwise
-          make them Freely Available, such as by posting said
-	  modifications to Usenet or an equivalent medium, or by allowing
-	  the author to include your modifications in the software.
+  The license agreements of most software companies try to keep users
+at the mercy of those companies.  By contrast, our General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  The
+General Public License applies to the Free Software Foundation's
+software and to any other program whose authors commit to using it.
+You can use it for your programs, too.
 
-       b) use the modified software only within your corporation or
-          organization.
+  When we speak of free software, we are referring to freedom, not
+price.  Specifically, the General Public License is designed to make
+sure that you have the freedom to give away or sell copies of free
+software, that you receive source code or can get it if you want it,
+that you can change the software or use pieces of it in new free
+programs; and that you know you can do these things.
 
-       c) give non-standard binaries non-standard names, with
-          instructions on where to get the original software distribution.
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
 
-       d) make other distribution arrangements with the author.
+  For example, if you distribute copies of a such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must tell them their rights.
 
-  3. You may distribute the software in object code or binary form,
-     provided that you do at least ONE of the following:
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
 
-       a) distribute the binaries and library files of the software,
-	  together with instructions (in the manual page or equivalent)
-	  on where to get the original distribution.
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
 
-       b) accompany the distribution with the machine-readable source of
-	  the software.
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
 
-       c) give non-standard binaries non-standard names, with
-          instructions on where to get the original software distribution.
+  0. This License Agreement applies to any program or other work which
+contains a notice placed by the copyright holder saying it may be
+distributed under the terms of this General Public License.  The
+"Program", below, refers to any such program or work, and a "work based
+on the Program" means either the Program or any work containing the
+Program or a portion of it, either verbatim or with modifications.  Each
+licensee is addressed as "you".
 
-       d) make other distribution arrangements with the author.
+  1. You may copy and distribute verbatim copies of the Program's source
+code as you receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice and
+disclaimer of warranty; keep intact all the notices that refer to this
+General Public License and to the absence of any warranty; and give any
+other recipients of the Program a copy of this General Public License
+along with the Program.  You may charge a fee for the physical act of
+transferring a copy.
 
-  4. You may modify and include the part of the software into any other
-     software (possibly commercial).  But some files in the distribution
-     are not written by the author, so that they are not under these terms.
+  2. You may modify your copy or copies of the Program or any portion of
+it, and copy and distribute such modifications under the terms of Paragraph
+1 above, provided that you also do the following:
 
-     For the list of those files and their copying conditions, see the
-     file LEGAL.
+    a) cause the modified files to carry prominent notices stating that
+    you changed the files and the date of any change; and
 
-  5. The scripts and library files supplied as input to or produced as 
-     output from the software do not automatically fall under the
-     copyright of the software, but belong to whomever generated them, 
-     and may be sold commercially, and may be aggregated with this
-     software.
+    b) cause the whole of any work that you distribute or publish, that
+    in whole or in part contains the Program or any part thereof, either
+    with or without modifications, to be licensed at no charge to all
+    third parties under the terms of this General Public License (except
+    that you may choose to grant warranty protection to some or all
+    third parties, at your option).
 
-  6. THIS SOFTWARE IS PROVIDED "AS IS" AND WITHOUT ANY EXPRESS OR
-     IMPLIED WARRANTIES, INCLUDING, WITHOUT LIMITATION, THE IMPLIED
-     WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-     PURPOSE.
+    c) If the modified program normally reads commands interactively when
+    run, you must cause it, when started running for such interactive use
+    in the simplest and most usual way, to print or display an
+    announcement including an appropriate copyright notice and a notice
+    that there is no warranty (or else, saying that you provide a
+    warranty) and that users may redistribute the program under these
+    conditions, and telling the user how to view a copy of this General
+    Public License.
+
+    d) You may charge a fee for the physical act of transferring a
+    copy, and you may at your option offer warranty protection in
+    exchange for a fee.
+
+Mere aggregation of another independent work with the Program (or its
+derivative) on a volume of a storage or distribution medium does not bring
+the other work under the scope of these terms.
+
+  3. You may copy and distribute the Program (or a portion or derivative of
+it, under Paragraph 2) in object code or executable form under the terms of
+Paragraphs 1 and 2 above provided that you also do one of the following:
+
+    a) accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of
+    Paragraphs 1 and 2 above; or,
+
+    b) accompany it with a written offer, valid for at least three
+    years, to give any third party free (except for a nominal charge
+    for the cost of distribution) a complete machine-readable copy of the
+    corresponding source code, to be distributed under the terms of
+    Paragraphs 1 and 2 above; or,
+
+    c) accompany it with the information you received as to where the
+    corresponding source code may be obtained.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form alone.)
+
+Source code for a work means the preferred form of the work for making
+modifications to it.  For an executable file, complete source code means
+all the source code for all modules it contains; but, as a special
+exception, it need not include source code for modules which are standard
+libraries that accompany the operating system on which the executable
+file runs, or for standard header files or definitions files that
+accompany that operating system.
+
+  4. You may not copy, modify, sublicense, distribute or transfer the
+Program except as expressly provided under this General Public License.
+Any attempt otherwise to copy, modify, sublicense, distribute or transfer
+the Program is void, and will automatically terminate your rights to use
+the Program under this License.  However, parties who have received
+copies, or rights to use copies, from you under this General Public
+License will not have their licenses terminated so long as such parties
+remain in full compliance.
+
+  5. By copying, distributing or modifying the Program (or any work based
+on the Program) you indicate your acceptance of this license to do so,
+and all its terms and conditions.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the original
+licensor to copy, distribute or modify the Program subject to these
+terms and conditions.  You may not impose any further restrictions on the
+recipients' exercise of the rights granted herein.
+
+  7. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of the license which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+the license, you may choose any version ever published by the Free Software
+Foundation.
+
+  8. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  9. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  10. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	Appendix: How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to humanity, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these
+terms.
+
+  To do so, attach the following notices to the program.  It is safest to
+attach them to the start of each source file to most effectively convey
+the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) 19yy  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 1, or (at your option)
+    any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) 19xx name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the
+appropriate parts of the General Public License.  Of course, the
+commands you use may be called something other than `show w' and `show
+c'; they could even be mouse-clicks or menu items--whatever suits your
+program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the
+  program `Gnomovision' (a program to direct compilers to make passes
+  at assemblers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+That's all there is to it!

-
-	* ext/tk/lib/tkafter.rb: support 'wait on a thread' and 'wait on

-
-Thu Oct  9 12:05:46 2003  Eric Sunshine <sunshine@sunshineco.com>
-
-	* configure.in: revived NextStep, OpenStep, and Rhapsody ports which
-	  had become unbuildable; enhanced --enable-fat-binary option so that
-	  it accepts a list of desired architectures (rather than assuming a
-	  fixed list), or defaults to a platform-appropriate list if user does
-	  not provide an explicit list; made the default list of architectures
-	  for MAB (fat binary) more comprehensive; now uses -fno-common even
-	  when building the interpreter (in addition to using it for
-	  extensions), thus allowing the interpreter to be embedded into a
-	  plugin module of an external project (in addition to allowing
-	  embedding directly into an application); added checks for
-	  <netinet/in_systm.h> (needed by `socket' extension) and getcwd(); now
-	  ensures that -I/usr/local/include is employed when extensions'
-	  extconf.rb scripts invoke have_header() since extension checks on
-	  NextStep and OpenStep will fail without it if the desired resource
-	  resides in the /usr/local tree; fixed formatting of --help message.
-
-	* Makefile.in: $(LIBRUBY_A) rule now deletes the archive before
-	  invoking $(AR) since `ar' on Apple/NeXT can not "update" MAB archives
-	  (see configure's --enable-fat-binary option); added rule for new
-	  missing/getcwd.c.
-
-	* defines.h: fixed endian handling during MAB build (see configure's
-	  --enable-fat-binary option) to ensure that all portions of the
-	  project see the correct WORDS_BIGENDIAN value (some extension modules
-	  were getting the wrong endian setting); added missing constants
-	  GETPGRP_VOID, WNOHANG, WUNTRACED, X_OK, and type pid_t for NextStep
-	  and OpenStep; removed unnecessary and problematic HAVE_SYS_WAIT_H
-	  define in NeXT section.
-
-	* dir.c: do not allow NAMLEN() macro to trust dirent::d_namlen on
-	  NextStep since, on some installations, this value always resolves
-	  uselessly to zero.
-
-	* dln.c: added error reporting to NextStep extension loader since the
-	  previous behavior of failing silently was not useful; now ensures
-	  that NSLINKMODULE_OPTION_BINDNOW compatibility constant is defined
-	  for OpenStep and Rhapsody; no longer includes <mach-o/dyld.h> twice
-	  on Rhapsody since this header lacks multiple-include protection,
-	  which resulted in "redefinition" compilation errors.
-
-	* main.c: also create hard reference to objc_msgSend() on NeXT
-	  platforms (in addition to Apple platforms).
-
-	* lib/mkmf.rb: now exports XCFLAGS from configure script to extension
-	  makefiles so that extensions can be built MAB (see configure's
-	  --enable-fat-binary option); also utilize XCFLAGS in cc_command()
-	  (but not cpp_command() because MAB flags are incompatible with
-	  direct invocation of `cpp').
-
-	* ext/curses/extconf.rb: now additionally checks for presence of these
-	  curses functions which are not present on NextStep or Openstep:
-	  bkgd(), bkgdset(), color(), curs(), getbkgd(), init(), scrl(), set(),
-	  setscrreg(), wattroff(), wattron(), wattrset(), wbkgd(), wbkgdset(),
-	  wscrl(), wsetscrreg()
-
-	* ext/curses/curses.c: added appropriate #ifdef's for additional set of
-	  curses functions now checked by extconf.rb; fixed curses_bkgd() and
-	  window_bkgd() to correctly return boolean result rather than numeric
-	  result; fixed window_getbkgd() to correctly signal an error by
-	  returning nil rather than -1.
-
-	* ext/etc/etc.c: setup_passwd() and setup_group() now check for null
-	  pointers before invoking rb_tainted_str_new2() upon fields extracted
-	  from `struct passwd' and `struct group' since null pointers in some
-	  fields are common on NextStep/OpenStep (especially so for the
-	  `pw_comment' field) and rb_tainted_str_new2() throws an exception
-	  when it receives a null pointer.
-
-	* ext/pty/pty.c: include "util.h" for strdup()/ruby_strdup() for
-	  platforms such as NextStep and OpenStep which lack strdup().
-
-	* ext/socket/getaddrinfo.c: cast first argument of getservbyname(),
-	  gethostbyaddr(), and gethostbyname() from (const char*) to non-const
-	  (char*) for older platforms such as NextStep and OpenStep.
-
-	* ext/socket/socket.c: include "util.h" for strdup()/ruby_strdup() for
-	  platforms such as NextStep and OpenStep which lack strdup(); include
-	  <netinet/in_systm.h> if present for NextStep and OpenStep; cast first
-	  argument of gethostbyaddr() and getservbyname() from (const char*) to
-	  non-const (char*) for older platforms.
-
-	* ext/syslog/syslog.c: include "util.h" for strdup()/ruby_strdup() for
-	  platforms such as NextStep and OpenStep which lack strdup().

-		    GNU GENERAL PUBLIC LICENSE
-		       Version 2, June 1991
-
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.
-                       59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-			    Preamble
-
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users.  This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it.  (Some other Free Software Foundation software is covered by
-the GNU Library General Public License instead.)  You can apply it to
-your programs, too.
-
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
-  To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have.  You must make sure that they, too, receive or can get the
-source code.  And you must show them these terms so they know their
-rights.
-
-  We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
-  Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software.  If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
-  Finally, any free program is threatened constantly by software
-patents.  We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary.  To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-		    GNU GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License.  The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language.  (Hereinafter, translation is included without limitation in
-the term "modification".)  Each licensee is addressed as "you".
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
-  1. You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
-  2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-    a) You must cause the modified files to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    b) You must cause any work that you distribute or publish, that in
-    whole or in part contains or is derived from the Program or any
-    part thereof, to be licensed as a whole at no charge to all third
-    parties under the terms of this License.
-
-    c) If the modified program normally reads commands interactively
-    when run, you must cause it, when started running for such
-    interactive use in the most ordinary way, to print or display an
-    announcement including an appropriate copyright notice and a
-    notice that there is no warranty (or else, saying that you provide
-    a warranty) and that users may redistribute the program under
-    these conditions, and telling the user how to view a copy of this
-    License.  (Exception: if the Program itself is interactive but
-    does not normally print such an announcement, your work based on
-    the Program is not required to print an announcement.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
-    a) Accompany it with the complete corresponding machine-readable
-    source code, which must be distributed under the terms of Sections
-    1 and 2 above on a medium customarily used for software interchange; or,
-
-    b) Accompany it with a written offer, valid for at least three
-    years, to give any third party, for a charge no more than your
-    cost of physically performing source distribution, a complete
-    machine-readable copy of the corresponding source code, to be
-    distributed under the terms of Sections 1 and 2 above on a medium
-    customarily used for software interchange; or,
-
-    c) Accompany it with the information you received as to the offer
-    to distribute corresponding source code.  (This alternative is
-    allowed only for noncommercial distribution and only if you
-    received the program in object code or executable form with such
-    an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it.  For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable.  However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License.  Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
-  5. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Program or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
-  6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
-  7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded.  In such case, this License incorporates
-the limitation as if written in the body of this License.
-
-  9. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time.  Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number.  If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation.  If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
-  10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission.  For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this.  Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
-			    NO WARRANTY
-
-  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
-  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.
-
-		     END OF TERMS AND CONDITIONS
-
-	    How to Apply These Terms to Your New Programs
-
-  If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
-  To do so, attach the following notices to the program.  It is safest
-to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the program's name and a brief idea of what it does.>
-    Copyright (C) <year>  <name of author>
-
-    This program is free software; you can redistribute it and/or modify
-    it under the terms of the GNU General Public License as published by
-    the Free Software Foundation; either version 2 of the License, or
-    (at your option) any later version.
-
-    This program is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
-    GNU General Public License for more details.
-
-    You should have received a copy of the GNU General Public License
-    along with this program; if not, write to the Free Software
-    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
-
-
-Also add information on how to contact you by electronic and paper mail.
-
-If the program is interactive, make it output a short notice like this
-when it starts in an interactive mode:
-
-    Gnomovision version 69, Copyright (C) year name of author
-    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
-    This is free software, and you are welcome to redistribute it
-    under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License.  Of course, the commands you use may
-be called something other than `show w' and `show c'; they could even be
-mouse-clicks or menu items--whatever suits your program.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the program, if
-necessary.  Here is a sample; alter the names:
-
-  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
-  `Gnomovision' (which makes passes at compilers) written by James Hacker.
-
-  <signature of Ty Coon>, 1 April 1989
-  Ty Coon, President of Vice
-
-This General Public License does not permit incorporating your program into
-proprietary programs.  If your program is a subroutine library, you may
-consider it more useful to permit linking proprietary applications with the
-library.  If this is what you want to do, use the GNU Library General
-Public License instead of this License.

-		  GNU LESSER GENERAL PUBLIC LICENSE
-		       Version 2.1, February 1999
-
- Copyright (C) 1991, 1999 Free Software Foundation, Inc.
-     59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-[This is the first released version of the Lesser GPL.  It also counts
- as the successor of the GNU Library Public License, version 2, hence
- the version number 2.1.]
-
-			    Preamble
-
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-Licenses are intended to guarantee your freedom to share and change
-free software--to make sure the software is free for all its users.
-
-  This license, the Lesser General Public License, applies to some
-specially designated software packages--typically libraries--of the
-Free Software Foundation and other authors who decide to use it.  You
-can use it too, but we suggest you first think carefully about whether
-this license or the ordinary General Public License is the better
-strategy to use in any particular case, based on the explanations below.
-
-  When we speak of free software, we are referring to freedom of use,
-not price.  Our General Public Licenses are designed to make sure that
-you have the freedom to distribute copies of free software (and charge
-for this service if you wish); that you receive source code or can get
-it if you want it; that you can change the software and use pieces of
-it in new free programs; and that you are informed that you can do
-these things.
-
-  To protect your rights, we need to make restrictions that forbid
-distributors to deny you these rights or to ask you to surrender these
-rights.  These restrictions translate to certain responsibilities for
-you if you distribute copies of the library or if you modify it.
-
-  For example, if you distribute copies of the library, whether gratis
-or for a fee, you must give the recipients all the rights that we gave
-you.  You must make sure that they, too, receive or can get the source
-code.  If you link other code with the library, you must provide
-complete object files to the recipients, so that they can relink them
-with the library after making changes to the library and recompiling
-it.  And you must show them these terms so they know their rights.
-
-  We protect your rights with a two-step method: (1) we copyright the
-library, and (2) we offer you this license, which gives you legal
-permission to copy, distribute and/or modify the library.
-
-  To protect each distributor, we want to make it very clear that
-there is no warranty for the free library.  Also, if the library is
-modified by someone else and passed on, the recipients should know
-that what they have is not the original version, so that the original
-author's reputation will not be affected by problems that might be
-introduced by others.
-
-  Finally, software patents pose a constant threat to the existence of
-any free program.  We wish to make sure that a company cannot
-effectively restrict the users of a free program by obtaining a
-restrictive license from a patent holder.  Therefore, we insist that
-any patent license obtained for a version of the library must be
-consistent with the full freedom of use specified in this license.
-
-  Most GNU software, including some libraries, is covered by the
-ordinary GNU General Public License.  This license, the GNU Lesser
-General Public License, applies to certain designated libraries, and
-is quite different from the ordinary General Public License.  We use
-this license for certain libraries in order to permit linking those
-libraries into non-free programs.
-
-  When a program is linked with a library, whether statically or using
-a shared library, the combination of the two is legally speaking a
-combined work, a derivative of the original library.  The ordinary
-General Public License therefore permits such linking only if the
-entire combination fits its criteria of freedom.  The Lesser General
-Public License permits more lax criteria for linking other code with
-the library.
-
-  We call this license the "Lesser" General Public License because it
-does Less to protect the user's freedom than the ordinary General
-Public License.  It also provides other free software developers Less
-of an advantage over competing non-free programs.  These disadvantages
-are the reason we use the ordinary General Public License for many
-libraries.  However, the Lesser license provides advantages in certain
-special circumstances.
-
-  For example, on rare occasions, there may be a special need to
-encourage the widest possible use of a certain library, so that it becomes
-a de-facto standard.  To achieve this, non-free programs must be
-allowed to use the library.  A more frequent case is that a free
-library does the same job as widely used non-free libraries.  In this
-case, there is little to gain by limiting the free library to free
-software only, so we use the Lesser General Public License.
-
-  In other cases, permission to use a particular library in non-free
-programs enables a greater number of people to use a large body of
-free software.  For example, permission to use the GNU C Library in
-non-free programs enables many more people to use the whole GNU
-operating system, as well as its variant, the GNU/Linux operating
-system.
-
-  Although the Lesser General Public License is Less protective of the
-users' freedom, it does ensure that the user of a program that is
-linked with the Library has the freedom and the wherewithal to run
-that program using a modified version of the Library.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.  Pay close attention to the difference between a
-"work based on the library" and a "work that uses the library".  The
-former contains code derived from the library, whereas the latter must
-be combined with the library in order to run.
-
-		  GNU LESSER GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License Agreement applies to any software library or other
-program which contains a notice placed by the copyright holder or
-other authorized party saying it may be distributed under the terms of
-this Lesser General Public License (also called "this License").
-Each licensee is addressed as "you".
-
-  A "library" means a collection of software functions and/or data
-prepared so as to be conveniently linked with application programs
-(which use some of those functions and data) to form executables.
-
-  The "Library", below, refers to any such software library or work
-which has been distributed under these terms.  A "work based on the
-Library" means either the Library or any derivative work under
-copyright law: that is to say, a work containing the Library or a
-portion of it, either verbatim or with modifications and/or translated
-straightforwardly into another language.  (Hereinafter, translation is
-included without limitation in the term "modification".)
-
-  "Source code" for a work means the preferred form of the work for
-making modifications to it.  For a library, complete source code means
-all the source code for all modules it contains, plus any associated
-interface definition files, plus the scripts used to control compilation
-and installation of the library.
-
-  Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running a program using the Library is not restricted, and output from
-such a program is covered only if its contents constitute a work based
-on the Library (independent of the use of the Library in a tool for
-writing it).  Whether that is true depends on what the Library does
-and what the program that uses the Library does.
-  
-  1. You may copy and distribute verbatim copies of the Library's
-complete source code as you receive it, in any medium, provided that
-you conspicuously and appropriately publish on each copy an
-appropriate copyright notice and disclaimer of warranty; keep intact
-all the notices that refer to this License and to the absence of any
-warranty; and distribute a copy of this License along with the
-Library.
-
-  You may charge a fee for the physical act of transferring a copy,
-and you may at your option offer warranty protection in exchange for a
-fee.
-
-  2. You may modify your copy or copies of the Library or any portion
-of it, thus forming a work based on the Library, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-    a) The modified work must itself be a software library.
-
-    b) You must cause the files modified to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    c) You must cause the whole of the work to be licensed at no
-    charge to all third parties under the terms of this License.
-
-    d) If a facility in the modified Library refers to a function or a
-    table of data to be supplied by an application program that uses
-    the facility, other than as an argument passed when the facility
-    is invoked, then you must make a good faith effort to ensure that,
-    in the event an application does not supply such function or
-    table, the facility still operates, and performs whatever part of
-    its purpose remains meaningful.
-
-    (For example, a function in a library to compute square roots has
-    a purpose that is entirely well-defined independent of the
-    application.  Therefore, Subsection 2d requires that any
-    application-supplied function or table used by this function must
-    be optional: if the application does not supply it, the square
-    root function must still compute square roots.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Library,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Library, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote
-it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Library.
-
-In addition, mere aggregation of another work not based on the Library
-with the Library (or with a work based on the Library) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may opt to apply the terms of the ordinary GNU General Public
-License instead of this License to a given copy of the Library.  To do
-this, you must alter all the notices that refer to this License, so
-that they refer to the ordinary GNU General Public License, version 2,
-instead of to this License.  (If a newer version than version 2 of the
-ordinary GNU General Public License has appeared, then you can specify
-that version instead if you wish.)  Do not make any other change in
-these notices.
-
-  Once this change is made in a given copy, it is irreversible for
-that copy, so the ordinary GNU General Public License applies to all
-subsequent copies and derivative works made from that copy.
-
-  This option is useful when you wish to copy part of the code of
-the Library into a program that is not a library.
-
-  4. You may copy and distribute the Library (or a portion or
-derivative of it, under Section 2) in object code or executable form
-under the terms of Sections 1 and 2 above provided that you accompany
-it with the complete corresponding machine-readable source code, which
-must be distributed under the terms of Sections 1 and 2 above on a
-medium customarily used for software interchange.
-
-  If distribution of object code is made by offering access to copy
-from a designated place, then offering equivalent access to copy the
-source code from the same place satisfies the requirement to
-distribute the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  5. A program that contains no derivative of any portion of the
-Library, but is designed to work with the Library by being compiled or
-linked with it, is called a "work that uses the Library".  Such a
-work, in isolation, is not a derivative work of the Library, and
-therefore falls outside the scope of this License.
-
-  However, linking a "work that uses the Library" with the Library
-creates an executable that is a derivative of the Library (because it
-contains portions of the Library), rather than a "work that uses the
-library".  The executable is therefore covered by this License.
-Section 6 states terms for distribution of such executables.
-
-  When a "work that uses the Library" uses material from a header file
-that is part of the Library, the object code for the work may be a
-derivative work of the Library even though the source code is not.
-Whether this is true is especially significant if the work can be
-linked without the Library, or if the work is itself a library.  The
-threshold for this to be true is not precisely defined by law.
-
-  If such an object file uses only numerical parameters, data
-structure layouts and accessors, and small macros and small inline
-functions (ten lines or less in length), then the use of the object
-file is unrestricted, regardless of whether it is legally a derivative
-work.  (Executables containing this object code plus portions of the
-Library will still fall under Section 6.)
-
-  Otherwise, if the work is a derivative of the Library, you may
-distribute the object code for the work under the terms of Section 6.
-Any executables containing that work also fall under Section 6,
-whether or not they are linked directly with the Library itself.
-
-  6. As an exception to the Sections above, you may also combine or
-link a "work that uses the Library" with the Library to produce a
-work containing portions of the Library, and distribute that work
-under terms of your choice, provided that the terms permit
-modification of the work for the customer's own use and reverse
-engineering for debugging such modifications.
-
-  You must give prominent notice with each copy of the work that the
-Library is used in it and that the Library and its use are covered by
-this License.  You must supply a copy of this License.  If the work
-during execution displays copyright notices, you must include the
-copyright notice for the Library among them, as well as a reference
-directing the user to the copy of this License.  Also, you must do one
-of these things:
-
-    a) Accompany the work with the complete corresponding
-    machine-readable source code for the Library including whatever
-    changes were used in the work (which must be distributed under
-    Sections 1 and 2 above); and, if the work is an executable linked
-    with the Library, with the complete machine-readable "work that
-    uses the Library", as object code and/or source code, so that the
-    user can modify the Library and then relink to produce a modified
-    executable containing the modified Library.  (It is understood
-    that the user who changes the contents of definitions files in the
-    Library will not necessarily be able to recompile the application
-    to use the modified definitions.)
-
-    b) Use a suitable shared library mechanism for linking with the
-    Library.  A suitable mechanism is one that (1) uses at run time a
-    copy of the library already present on the user's computer system,
-    rather than copying library functions into the executable, and (2)
-    will operate properly with a modified version of the library, if
-    the user installs one, as long as the modified version is
-    interface-compatible with the version that the work was made with.
-
-    c) Accompany the work with a written offer, valid for at
-    least three years, to give the same user the materials
-    specified in Subsection 6a, above, for a charge no more
-    than the cost of performing this distribution.
-
-    d) If distribution of the work is made by offering access to copy
-    from a designated place, offer equivalent access to copy the above
-    specified materials from the same place.
-
-    e) Verify that the user has already received a copy of these
-    materials or that you have already sent this user a copy.
-
-  For an executable, the required form of the "work that uses the
-Library" must include any data and utility programs needed for
-reproducing the executable from it.  However, as a special exception,
-the materials to be distributed need not include anything that is
-normally distributed (in either source or binary form) with the major
-components (compiler, kernel, and so on) of the operating system on
-which the executable runs, unless that component itself accompanies
-the executable.
-
-  It may happen that this requirement contradicts the license
-restrictions of other proprietary libraries that do not normally
-accompany the operating system.  Such a contradiction means you cannot
-use both them and the Library together in an executable that you
-distribute.
-
-  7. You may place library facilities that are a work based on the
-Library side-by-side in a single library together with other library
-facilities not covered by this License, and distribute such a combined
-library, provided that the separate distribution of the work based on
-the Library and of the other library facilities is otherwise
-permitted, and provided that you do these two things:
-
-    a) Accompany the combined library with a copy of the same work
-    based on the Library, uncombined with any other library
-    facilities.  This must be distributed under the terms of the
-    Sections above.
-
-    b) Give prominent notice with the combined library of the fact
-    that part of it is a work based on the Library, and explaining
-    where to find the accompanying uncombined form of the same work.
-
-  8. You may not copy, modify, sublicense, link with, or distribute
-the Library except as expressly provided under this License.  Any
-attempt otherwise to copy, modify, sublicense, link with, or
-distribute the Library is void, and will automatically terminate your
-rights under this License.  However, parties who have received copies,
-or rights, from you under this License will not have their licenses
-terminated so long as such parties remain in full compliance.
-
-  9. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Library or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Library (or any work based on the
-Library), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Library or works based on it.
-
-  10. Each time you redistribute the Library (or any work based on the
-Library), the recipient automatically receives a license from the
-original licensor to copy, distribute, link with or modify the Library
-subject to these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties with
-this License.
-
-  11. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Library at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Library by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Library.
-
-If any portion of this section is held invalid or unenforceable under any
-particular circumstance, the balance of the section is intended to apply,
-and the section as a whole is intended to apply in other circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  12. If the distribution and/or use of the Library is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Library under this License may add
-an explicit geographical distribution limitation excluding those countries,
-so that distribution is permitted only in or among countries not thus
-excluded.  In such case, this License incorporates the limitation as if
-written in the body of this License.
-
-  13. The Free Software Foundation may publish revised and/or new
-versions of the Lesser General Public License from time to time.
-Such new versions will be similar in spirit to the present version,
-but may differ in detail to address new problems or concerns.
-
-Each version is given a distinguishing version number.  If the Library
-specifies a version number of this License which applies to it and
-"any later version", you have the option of following the terms and
-conditions either of that version or of any later version published by
-the Free Software Foundation.  If the Library does not specify a
-license version number, you may choose any version ever published by
-the Free Software Foundation.
-
-  14. If you wish to incorporate parts of the Library into other free
-programs whose distribution conditions are incompatible with these,
-write to the author to ask for permission.  For software which is
-copyrighted by the Free Software Foundation, write to the Free
-Software Foundation; we sometimes make exceptions for this.  Our
-decision will be guided by the two goals of preserving the free status
-of all derivatives of our free software and of promoting the sharing
-and reuse of software generally.
-
-			    NO WARRANTY
-
-  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
-WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
-EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
-OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
-KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
-IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
-LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
-THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
-  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
-WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
-AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
-FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
-CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
-LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
-RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
-FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
-SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
-DAMAGES.
-
-		     END OF TERMS AND CONDITIONS
-
-           How to Apply These Terms to Your New Libraries
-
-  If you develop a new library, and you want it to be of the greatest
-possible use to the public, we recommend making it free software that
-everyone can redistribute and change.  You can do so by permitting
-redistribution under these terms (or, alternatively, under the terms of the
-ordinary General Public License).
-
-  To apply these terms, attach the following notices to the library.  It is
-safest to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least the
-"copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the library's name and a brief idea of what it does.>
-    Copyright (C) <year>  <name of author>
-
-    This library is free software; you can redistribute it and/or
-    modify it under the terms of the GNU Lesser General Public
-    License as published by the Free Software Foundation; either
-    version 2.1 of the License, or (at your option) any later version.
-
-    This library is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
-    Lesser General Public License for more details.
-
-    You should have received a copy of the GNU Lesser General Public
-    License along with this library; if not, write to the Free Software
-    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
-
-Also add information on how to contact you by electronic and paper mail.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the library, if
-necessary.  Here is a sample; alter the names:
-
-  Yoyodyne, Inc., hereby disclaims all copyright interest in the
-  library `Frob' (a library for tweaking knobs) written by James Random Hacker.
-
-  <signature of Ty Coon>, 1 April 1990
-  Ty Coon, President of Vice
-
-That's all there is to it!

 1.3 Convert VALUE into C data
 
-The data for type T_NIL, T_FALSE, T_TRUE are nil, true, false
-respectively.  They are singletons for the data type.
-
-The T_FIXNUM data is a 31bit length fixed integer (63bit length on
-some machines), which can be convert to a C integer by using the
-FIX2INT() macro.  There is also NUM2INT() which converts any Ruby
-numbers into C integers.  The NUM2INT() macro includes a type check, so
-an exception will be raised if the conversion failed.  NUM2DBL() can
-be used to retrieve the double float value in same way.
-
-To get char* from a VALUE, version 1.7 recommend to use new macros
-StringValue() and StringValuePtr().  StringValue(var) replaces var's
-value to the result of "var.to_str()".  StringValuePtr(var) does same
-replacement and returns char* representation of var.  These macros
-will skip the replacement if var is a String.  Notice that the macros
-requires to take only lvalue as their argument, to change the value
-of var in the replacement. 
-
-In version 1.6 or earlier, STR2CSTR() was used to do same thing
-but now it is obsoleted in version 1.7 because of STR2CSTR() has
-a risk of dangling pointer problem in to_str() impliclit conversion.
-
-Other data types have corresponding C structures, e.g. struct RArray
-for T_ARRAY etc. The VALUE of the type which has corresponding structure
-can be cast to retrieve the pointer to the struct.  The casting macro
-will be of the form RXXXX for each data type; for instance, RARRAY(obj). 
-See "ruby.h".
-
-For example, `RSTRING(str)->len' is the way to get the size of the
-Ruby String object.  The allocated region can be accessed by
-`RSTRING(str)->ptr'.  For arrays, use `RARRAY(ary)->len' and
-`RARRAY(ary)->ptr' respectively.
-
-Notice: Do not change the value of the structure directly, unless you
-are responsible for the result.  This ends up being the cause of interesting
-bugs.

 (4) write C code.
 
-You need to write C code for your extension library.  If your library
-has only one source file, choosing ``LIBRARY.c'' as a file name is
-preferred.  On the other hand, in case your library has multiple source
-files, avoid choosing ``LIBRARY.c'' for a file name.  It may conflict
-with an intermediate file ``LIBRARY.o'' on some platforms.
-
-Ruby will execute the initializing function named ``Init_LIBRARY'' in
-the library.  For example, ``Init_dbm()'' will be executed when loading
-the library.

-* "in" modifier, to annotate, or to encourage assertion.
-* selector namespace - something like generic-flet in CLOS, to help RubyBehavior
-* private instance variable (as in Python?) @_foo in class Foo => @_Foo_foo
-* warn/error "bare word" method, like "foo",  you should type "foo()"

-- fork_and_kill_other_threads.
-- signal list (Signal::trap, Signal::list).
-- move NameError under StandardError.
-- Integer#to_s(base)
-- Hash::new{default}
-- hash etc. should handle self referenceing array/hash
-- Array#select(n1,n2...) works like Array#indexes(n1,n2...)
-- use Mersenne Twister RNG for random.
-- deprecate Array#indexes, and Array#indices.
-- remove dependency on MAXPATHLEN.

-* synchronized method - synchronized{...}, synchronized :foo, :bar
-* Array#&, Array#| to allow duplication. ???
-* way to specify immortal (fork endurance) thread;
-* or raise ForkException to every thread but fork caller.
-* new user-defined marshal scheme. _dump(dumper), _load(restorer)
-* library to load per-user profile seeking .ruby_profile or ruby.ini file.
-* warning framework (warn, warning for Ruby level)
-* marshal should not depend on sprintf (works bad with locale).
-* ternary arg pow: a.pow(b,c) == a**b%c
-* new caller(), e.g. call_stack; needs better name.
-* pointer share mechanism similar to one in String for Array.

-= How to build ruby using Borland C++
-
-== Requirement
-
-(1) Borland C++ 5.0 or later.
-
-(2) If you want to run `((%make clean%))' or `((%make distclean%))'
-    properly, you must install UNIX compatible `((%rm%))' command on
-    your ((|PATH|)).
-
-(3) Please set environment variable (({INCLUDE})), (({LIB})), (({PATH}))
-    to run required commands properly from the command line.
-
-    Note: building ruby requires following commands.
-     * make
-     * bcc
-     * tlib
-     * ilink
-
-== How to compile and install
-
-(1) Execute bcc32\configure.bat on your build directory.
-     ex. c:\ruby-1.6.7>bcc32\configure.bat
-     
-(2) Change ((|RUBY_INSTALL_NAME|)) and ((|RUBY_SO_NAME|)) in (({Makefile}))
-    if you want to change the name of the executable files. 
-    And add ((|RUBYW_INSTALL_NAME|)) to change the name of the
-    executable without console window if also you want.
-
-(3) Run `((%make%))'
-
-(4) Run `((%make test%))'
-
-(5) Run `((%make DESTDIR=<install_directory> install%))'
-
-    This command will create following directories and install files onto them.
-      * <install_directory>\bin
-      * <install_directory>\lib

-== Icons
-
-Any icon files(*.ico) in the build directory, directories specified with
-((|icondirs|)) make variable and (({win32})) directory under the ruby
-source directory will be included in DLL or executable files, according
-to their base names.
-    $(RUBY_INSTALL_NAME).ico or ruby.ico   --> $(RUBY_INSTALL_NAME).exe
-    $(RUBYW_INSTALL_NAME).ico or rubyw.ico --> $(RUBYW_INSTALL_NAME).exe
-    the others                             --> $(RUBY_SO_NAME).dll
-
-Although no icons are distributed with the ruby source or in the official 
-site, you can use anything you like. For example, followings are written 
-in Japanese, but you can download at least.
-
-* ((<URL:http://member.nifty.ne.jp/ueivu/rubyico.html>)) or
-  ((<zipped icons|URL:http://member.nifty.ne.jp/ueivu/Ruby_ico.zip>))
-* ((<URL:http://homepage1.nifty.com/a_nakata/ruby/>)) or
-  ((<icon itself|URL:http://homepage1.nifty.com/a_nakata/ruby/RubyIcon.ico>))
-
-== Build examples
-
-* Build on the ruby source directory.
-
-  ex.)
-    ruby source directory:  C:\ruby
-    build directory:        C:\ruby
-    install directory:      C:\usr\local
-
-    C:
-    cd \ruby
-    bcc32\configure
-    make
-    make test
-    make DESTDIR=/usr/local install
-
-* Build on the relative directory from the ruby source directory and CPU type 
-  i386.
-
-  ex.)
-    ruby source directory:  C:\ruby
-    build directory:        C:\ruby\bccwin32
-    install directory:      C:\usr\local
-    CPU                     i386
-    
-    C:
-    cd \ruby
-    mkdir bccwin32
-    cd bccwin32
-    ..\bcc32\configure target i386-bccwin32
-    make
-    make test
-    make DESTDIR=/usr/local install
-
-* Build on the different drive.
-
-  ex.)
-    ruby source directory:  C:\src\ruby
-    build directory:        D:\build\ruby
-    install directory:      C:\usr\local
-
-    D:
-    cd D:\build\ruby
-    C:\src\ruby\bcc32\configure
-    make
-    make test
-    make DESTDIR=C:/usr/local install
-
-== Bugs
-
-You can ((*NOT*)) use a path name contains any white space characters as
-the ruby source directory, this restriction comes from the behavior of
-(({!INCLUDE})) directives of (({MAKE})).
-((- you may call it a bug. -))

-* How to compile and install on djgpp
-
-This is what you need to do to compile and install Ruby:
-
-  1. Run configure.bat, which will generate config.h and Makefile
-     (GNU sed required).
-     Message like this is normal:
-       sed.exe: can't read 123456789: No such file or directory (ENOENT)
-
-  2. Edit defines.h if you need.  Probably this step will not need.
-
-  3. Remove comment mark(#) before the module names from ext/Setup.dj (or
-     add module names if not present).
-
-  4. Run make.
-
-  5. Optionally, run 'make test' to check whether the compiled Ruby
-     interpreter works well.  If you see the message "test succeeded",
-     your ruby works as it should (hopefully).
-
-  6. Run 'make install'

-= command line options
-
-: -W option
-
-  new option to specify warning level. -W0 to shut up warnings, -W1 for normal level,
-  -W2 for verbose level.  -w equals to -W2.
-
-= language syntax
-
-: arbitrary delimited string array
-
-  %W(...) notation, word list literal like %w(...) with the
-  exception that #{} interpolation is allowed.
-
-: arbitrary delimited symbol literl
-
-  :"foo", :"foo#{bar}", etc.
-
-: expression interpolation in strings
-
-  Now arbitrary statements are allowed inside #{} interpolation
-  without escapes.  In other hand, they can no longer access to
-  variables defined in eval.
-
-: negative number literals
-
-  Digits preceded minus sign is a literal integer.
-
-: array expansion
-
-  Fixed with the following behavior:
-
-    a = *[1]
-    p a #=> [1]
-
-  Now 1-element array in rhs is expanded properly.
-
-    a = *[1]
-    p a #=> 1
-
-: break and next
-
-  Extended to take an optional expression, which is used as a value
-  for termination.
-
-: direct assignment to Foo::Bar is allowed
-
-  also, you can define "class Foo::Bar; end".
-
-= language core
-
-: $stdin, $stdout, $stderr
-
-  can be assignable again.  the original stdio are preserved as STDIN,
-  STDOUT, STDERR.
-
-: $VERBOSE now has 3 levels
-
-  nil - silence, false - medium (default), true - verbose
-
-: allocation framework
-
-  any instance of class can be allocated by class.allocate,
-  (except for a few classes).
-
-: comparison of exception classes in a rescue clause
-
-  changed to use Module#=== for comparing $! with the exception
-  class specified in each rescue clause.
-
-  as the previous behavior was to use kind_of?, the effect is limited
-  to the SystemCallError case.  SystemCallError.=== has been newly
-  defined to return true when the two have the same errno.  With this
-  change, SystemCallError's with the same errno, such as Errno::EAGAIN
-  and Errno::EWOULDBLOCK, can both be rescued by listing just one of
-  them.
-
-: constants lookup
-
-  improved at the performance of searching by using an internal hash
-  table.
-
-  calls const_missing method of the class/module, if constant is not
-  found in the look up path.
-
-: expression parenthesis in the first argument
-
-  altered to get the following code (note the space after p):
-
-    p ("xx"*2).to_i
-
-  Interpreted as:
-
-    p (("xx"*2).to_i)
-
-  Instead of:
-
-    (p("xx"*2)).to_i
-
-: implicit comparison in conditional expressions
-
-  Obsoleted except when it is used in -e.
-
-  : between Range and $.
-      Use explicit comparison instead.
-
-  : between Regexp and $_
-      Use the unary method ~/re/ instead.
-
-: to_str
-
-  added to get objects which define to_str() treated as String's.
-
-  now almost all the built-in methods try each argument with to_str()
-  when they expect it to be a String.
-
-    foo = Object.new
-    class <<foo
-      def to_str
-        "foo"
-      end
-    end
-    p File.open(foo)
-    => -:7:in `open': wrong argument type Object (expected String) (TypeError)
-       ruby 1.6.4 (2001-04-19) [i586-linux]
-    => -:7:in `open': No such file or directory - "foo" (Errno::ENOENT)
-       ruby 1.7.0 (2001-05-02) [i586-linux]
-
-: multiple assignment behavior
-
-  Fixed so that "*a = nil" results in "a == []".
-
-= changes in core class library
-
-: open
-
-  Extended so that when the third argument is permission flags it
-  calls open(2) instead of fopen(3).
-
-: sprintf
-
-  new format specifier "%p" is available.
-
-: lambda and proc
-
-  Proc object returns from these methods has the following attributes:
-
-  * strict argument number check
-  * break and return terminates the proc execution.
-
-: warn(message)
-
-  a method to give warnings.
-
-: abort()
-
-  takes optional terminate message argument.
-
-: Object#initialize_copy
-
-  copy constructor for clone and dup.
-
-: Object#instance_variable_set, Object#instance_variable_get
-
-  added.
-
-: Object#singleton_method_removed
-: Object#singleton_method_undefined
-
-  Added.
-
-: Array#transpose
-
-  added.
-
-: Array#fetch(index [, default])
-
-  Added.  If a default value isn't given, raises index error if index
-  is out of range.
-
-: Array#insert(n, other, ...)
-
-  Added. [ruby-talk:14289]
-
-  This is much the same as (({ary[n,0] = [other,...]})) except
-  returing self.
-
-    ary = [0,1,2,3]
-    ary[2, 0] = [4, 5, 6]
-    p ary
-
-    ary = [0,1,2,3]
-    ary.insert(2, 4, 5, 6)
-    p ary
-
-: Array#sort!
-
-  Changed to always return self without checking whether the sequence
-  of the elements was modified or not.
-
-  Beware that this behavior is not guaranteed to continue in the
-  future.  Do not rely on its return value. [ruby-dev:12506]
-
-: Array#filter
-
-  Previously deprecated, now removed.  Use Array#collect!.
-
-: Array#pack, String#unpack
-
-  Allows comment in template strings.
-
-: Array#pack, String#unpack
-
-  New templates 'q' and 'Q' for 64bit integer (signed and unsigned respectively).
-
-: Array#new
-
-  Now takes block to fill initial values.  E.g.
-
-	Array.new(10) { |i| i + 1 }
-	=> [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
-
-: Array#fill
-
-  Takes block to get the values to fill.
-
-: Array#fetch
-
-  Takes block to get the default value.
-
-: Array#zip
-
-  added.
-
-: Hash#update
-
-  Takes block to resolve key conflict.
-
-: Hash#merge and Hash#merge!
-
-  update hash.  Hash#merge! is a synonym of Hash#update.
-
-: String#split
-
-  if "sep" argument is a string, regular expression meta characters
-  are escaped internally.
-
-: String#rstrip
-
-  chop off NULs at the end of strings.
-
-: String#to_i
-
-  Now accepts optional base argument.
-
-	"101".to_i(10) => 101

-    => Thu Jan 01 08:59:59 JST 1970
-
-: Time#to_a
-: Time#zone
-
-  Made to return "UTC" under gmtime.  It used to return a platform
-  dependent value, typically "GMT", in 1.6 and prior.
-
-: Marshal to use marshal_dump and marshal_load
-
-  if a dumping object responds to 'marshal_dump', Marshal.dump calls
-  it, and dumps object returned.  Marshal.load allocates a new instance
-  using "allocate", then calls its "marshal_load" with dumped data.

-
-: NameError and NoMethodError
-
-  Moved and now NoMethodError < NameError < StandardError.
-
-: NoMethodError
-
-  Added. [ruby-dev:12763]
-
-: NotImplementError
-
-  Finally obsoleted.  Use NotImplementedError.
-
-: SystemCallError.===
-
-  Added. (See the "Comparison of exception classes in a rescue clause"
-  paragraph above) [ruby-dev:12670]

-irb -- interactive ruby
-		$Release Version: 0.9 $
-		$Revision$
-		$Date$
-		by Keiju ISHITSUKA(keiju@ishitsuka.com)
-		by gotoken-san who is original translater from japanese version
-
-=begin
-= What is irb?
-
-irb stands for `interactive ruby'. irb is a tool to execute interactively
-ruby expressions read from stdin. 
-
-= Invoking
-
-  % irb
-
-= Usage
-
-Use of irb is easy if you know ruby.  Executing irb, prompts are 
-displayed as follows. Then, enter expression of ruby. A input is
-executed when it is syntacticaly completed. 
-
-  dim% irb
-  irb(main):001:0> 1+2
-  3
-  irb(main):002:0> class Foo
-  irb(main):003:1>  def foo
-  irb(main):004:2>    print 1
-  irb(main):005:2>  end
-  irb(main):006:1> end
-  nil
-  irb(main):007:0> 
-
-And, Readline extesion module can be used with irb. Using Readline
-is the standard default action if Readline is installed. 
-
-= Command line option
-
-  irb.rb [options] file_name opts
-  options:
-  -f		    suppress read ~/.irbrc 
-  -m		    bc mode (fraction or matrix are available)
-  -d                set $DEBUG  to true (same as `ruby -d')
-  -Kc		    same as `ruby -Kc'
-  -r load-module    same as `ruby -r'
-  --verbose	    command input is echoed(default)
-  --noverbose	    command input isn't echoed
-  --echo	    commands are echoed immediately before execution(default)
-  --noecho	    commands aren't echoed immediately before execution
-  --inspect	    uses `inspect' for output (the default except bc mode)
-  --noinspect	    doesn't uses inspect for output
-  --readline	    uses Readline extension module
-  --noreadline	    doesn't use Readline extension module
-  --prompt prompt-mode
-  --prompt-mode prompt-mode
-		    switches prompt mode. Pre-defined prompt modes are
-		    `default', `simple', `xmp' and `inf-ruby'
-			    
-  --inf-ruby-mode   uses prompt appreciate for inf-ruby-mode on emacs. 
-		    Suppresses --readline. 
-  --simple-prompt   simple prompt mode
-  --noprompt	    no prompt
-  --tracer	    display trace for each execution of commands.
-  --back-trace-limit n
-		    displayes backtrace top n and tail n. The default
-		    value is 16. 
-  --irb_debug n	    sets internal debug level to n (It shouldn't be used)
-  -v, --version	    prints the version of irb
-
-= Configurations
-
-irb reads `~/.irbrc' when it is invoked. If `~/.irbrb' doesn't exist
-irb try to read in the order `.irbrc', `irb.rc', `_irbrc' then `$irbrc'. 
-
-The following is altanative to the command line option. To use them
-type as follows in an irb session. 
-
-  IRB.conf[:IRB_NAME]="irb"
-  IRB.conf[:MATH_MODE]=false
-  IRB.conf[:USE_TRACER]=false
-  IRB.conf[:USE_LOADER]=false
-  IRB.conf[:IGNORE_SIGINT]=true
-  IRB.conf[:IGNORE_EOF]=false
-  IRB.conf[:INSPECT_MODE]=nil
-  IRB.conf[:IRB_RC] = nil
-  IRB.conf[:BACK_TRACE_LIMIT]=16
-  IRB.conf[:USE_LOADER] = false
-  IRB.conf[:USE_READLINE] = nil
-  IRB.conf[:USE_TRACER] = false
-  IRB.conf[:IGNORE_SIGINT] = true
-  IRB.conf[:IGNORE_EOF] = false
-  IRB.conf[:PROMPT_MODE] = :DEFALUT
-  IRB.conf[:PROMPT] = {...}
-  IRB.conf[:DEBUG_LEVEL]=0
-  IRB.conf[:VERBOSE]=true
-
-== Customizing prompt
-
-To costomize the prompt you set a variable
-
-  IRB.conf[:PROMPT]
-
-For example, describe as follows in `.irbrc'. 
-
-  IRB.conf[:PROMPT][:MY_PROMPT] = { # name of prompt mode
-    :PROMPT_I => nil,		  # normal prompt
-    :PROMPT_S => nil,		  # prompt for continuated strings
-    :PROMPT_C => nil,		  # prompt for continuated statement
-    :RETURN => "    ==>%s\n"	  # format to return value
-  }
-
-Then, invoke irb with the above prompt mode by
-
-  % irb --prompt my-prompt
-
-Or add the following in `.irbrc'. 
-
-  IRB.conf[:PROMPT_MODE] = :MY_PROMPT
-
-Constants PROMPT_I, PROMPT_S and PROMPT_C specifies the format. 
-In the prompt specification, some special strings are available. 
-
-  %N	command name which is running
-  %m	to_s of main object (self)
-  %M	inspect of main object (self)
-  %l	type of string(", ', /, ]), `]' is inner %w[...]
-  %NNi	indent level. NN is degits and means as same as printf("%NNd"). 
-        It can be ommited
-  %NNn	line number. 
-  %%    %
-
-For instance, the default prompt mode is defined as follows:
-
-IRB.conf[:PROMPT_MODE][:DEFAULT] = {
-      :PROMPT_I => "%N(%m):%03n:%i> ",
-      :PROMPT_S => "%N(%m):%03n:%i%l ",
-      :PROMPT_C => "%N(%m):%03n:%i* ",
-      :RETURN => "%s\n"
-} 
-
-RETURN is used to printf. 
-
-== Configurating subirb
-
-The command line option or IRB.conf specify the default behavior of
-(sub)irb. On the other hand, each conf of in the next sction `6. Command' 
-is used to individually configurate (sub)irb. 
-
-If proc is set to IRB.conf[:IRB_RC], its subirb will be invoked after
-execution of that proc under giving the context of irb as its
-aregument. By this mechanism each subirb can be configurated. 
-
-= Command
-
-For irb commands, both simple name and `irb_'-prefixed name are prepared. 
-
---- exit, quit, irb_exit

-
---- conf.math_mode
-    Whether bc mode or not. 
-
---- conf.use_loader = true/false

-#    Whether verbose messages are display or not. 
-
---- cws, chws, irb_change_workspace [obj]
-    obj will be self. If obj is omitted, self will be home-object, or
-    the main object of first started irb.
-

-
---- jobs, irb_jobs
-    List of subirb
-
---- fg n, irb_fg n
-    Switch into specified subirb. The following is candidates of n:
-
-      irb number
-      thhread
-      irb object
-      self(obj which is specified of irb obj)
-
---- kill n, irb_kill n
-    Kill subirb. The means of n is as same as the case of irb_fg.

-
-= System variable
-
---- _  The latest value of evaluation (it is local)
---- __ The history of evaluation values.
-    __[line_no] return an evaluation value of line number<line_no>. If
-    line_no is a negative, return value before -<line_no> from latest
-    value.

-
-= Restrictions
-
-Because irb evaluates the inputs immediately after the imput is
-syntactically completed, irb gives slight different result than
-directly use ruby. Known difference is pointed out here. 
-
-
-== Declaration of the local variable
-
-The following causes an error in ruby:
-
-  eval "foo = 0"
-  foo
-  --
-  -:2: undefined local variable or method `foo' for #<Object:0x40283118> (NameError)
-  ---
-  NameError
-
-Though, the above will successfully done by irb. 
-
-  >> eval "foo = 0"
- => 0
- >> foo
- => 0
-
-Ruby evaluates a code after reading entire of code and determination
-of the scope of local variables. On the other hand, irb do
-immediately. More precisely, irb evaluate at first
-
-  evel "foo = 0" 
-
-then foo is defined on this timing. It is because of this
-incompatibility.
-
-If you'd like to detect those differences, begin...end can be used:
-
-  >> begin
-  ?>   eval "foo = 0"
-  >>   foo
-  >> end
-  NameError: undefined local variable or method `foo' for #<Object:0x4013d0f0>
-  (irb):3
-  (irb_local_binding):1:in `eval'
-
-== Here-document
-
-Implementation of Here-document is incomplete. 
-
-== Symbol
-
-Irb can not always recognize a symbol as to be Symbol. Concretely, an
-expression have completed, however Irb regard it as continuation line.

-=begin
-
-= What's shell.rb?
-
-It realizes a wish to do execution of commands with filters and pipes
-like sh/csh by using just native facilities of ruby.
-
-= Main classes
-
-== Shell
-
-Every shell object has its own current working directory, and executes
-each command as if it stands in the directory.
-
---- Shell#cwd
---- Shell#dir
---- Shell#getwd
---- Shell#pwd
-
-      Returns the current directory
-
---- Shell#system_path
-
-      Returns the command search path in an array
-
---- Shell#umask
-
-      Returns the umask
-
-== Filter
-
-Any result of command exection is a Filter.  Filter include
-Enumerable, therefore a Filter object can use all Enumerable
-facilities.
-
-= Main methods
-
-== Command definitions
-
-In order to execute a command on your OS, you need to define it as a
-Shell method.
-
-Alternatively, you can execute any command via Shell#system even if it
-is not defined.
-
---- Shell.def_system_command(command, path = command)
-
-      Defines a command.  Registers <path> as a Shell method
-      <command>.
-
-      ex)
-      Shell.def_system_command "ls"
-        Defines ls.
-
-      Shell.def_system_command "sys_sort", "sort"
-        Defines sys_sort as sort.
-
---- Shell.undef_system_command(command)
-
-      Undefines a commmand
-
---- Shell.alias_command(ali, command, *opts) {...}
-
-      Aliases a command.
-
-      ex)
-        Shell.alias_command "lsC", "ls", "-CBF", "--show-control-chars"
-        Shell.alias_command("lsC", "ls"){|*opts| ["-CBF", "--show-control-chars", *opts]}
-
---- Shell.unalias_command(ali)
-
-      Unaliases a command.
-
---- Shell.install_system_commands(pre = "sys_")
-
-      Defines all commands in the default_system_path as Shell method,
-      all with <pre> prefixed to their names.
-
-== Creation
-
---- Shell.new
-
-      Creates a Shell object which current directory is set to the
-      process current directory.
-
---- Shell.cd(path)
-
-      Creates a Shell object which current directory is set to
-      <path>.
-
-== Process management
-
---- Shell#jobs
-
-      Returns a list of scheduled jobs.
-
---- Shell#kill sig, job
-
-      Sends a signal <sig> to <job>.
-
-== Current directory operations
-
---- Shell#cd(path, &block)
---- Shell#chdir
-
-      Changes the current directory to <path>.  If a block is given,
-      it restores the current directory when the block ends.
-
---- Shell#pushd(path = nil, &block)
---- Shell#pushdir
-
-      Pushes the current directory to the directory stack, changing
-      the current directory to <path>.  If <path> is omitted, it
-      exchanges its current directory and the top of its directory
-      stack.  If a block is given, it restores the current directory
-      when the block ends.
-
---- Shell#popd
---- Shell#popdir
-
-      Pops a directory from the directory stack, and sets the current
-      directory to it.
-
-== File and directory operations
-
---- Shell#foreach(path = nil, &block)
-
-      Same as:
-        File#foreach (when path is a file)
-        Dir#foreach (when path is a directory)
-
---- Shell#open(path, mode)
-
-      Same as:
-        File#open (when path is a file)
-        Dir#open (when path is a directory)
-
---- Shell#unlink(path)
-
-      Same as:
-        Dir#open (when path is a file)
-        Dir#unlink (when path is a directory)
-
---- Shell#test(command, file1, file2)
---- Shell#[command, file1, file2]
-
-      Same as test().
-      ex)
-          sh[?e, "foo"]
-          sh[:e, "foo"]
-          sh["e", "foo"]
-          sh[:exists?, "foo"]
-          sh["exists?", "foo"]
-
---- Shell#mkdir(*path)
-
-      Same as Dir.mkdir (with multiple directories allowed)
-
---- Shell#rmdir(*path)
-
-      Same as Dir.rmdir (with multiple directories allowed)
-
-== Command execution
-
---- System#system(command, *opts)
-
-      Executes <command> with <opts>.
-
-      ex)
-        print sh.system("ls", "-l")
-        sh.system("ls", "-l") | sh.head > STDOUT
-
---- System#rehash
-
-      Does rehash.
-
---- Shell#transact &block
-
-      Executes a block as self.
-      ex)
-        sh.transact{system("ls", "-l") | head > STDOUT}
-
---- Shell#out(dev = STDOUT, &block)
-
-      Does transact, with redirecting the result output to <dev>.
-
-== Internal commands
-
---- Shell#echo(*strings)
---- Shell#cat(*files)
---- Shell#glob(patten)
---- Shell#tee(file)
-
-      Return Filter objects, which are results of their execution.
-
---- Filter#each &block
-
-      Iterates a block for each line of it.
-
---- Filter#<(src)
-
-      Inputs from <src>, which is either a string of a file name or an
-      IO.
-
---- Filter#>(to)
-
-      Outputs to <to>, which is either a string of a file name or an
-      IO.
-
---- Filter#>>(to)
-
-      Appends the ouput to <to>, which is either a string of a file
-      name or an IO.
-
---- Filter#|(filter)
-
-      Processes a pipeline.
-
---- Filter#+(filter)
-
-      (filter1 + filter2) outputs filter1, and then outputs filter2.
-
---- Filter#to_a
---- Filter#to_s
-
-== Built-in commands
-
---- Shell#atime(file)
---- Shell#basename(file, *opt)
---- Shell#chmod(mode, *files)
---- Shell#chown(owner, group, *file)
---- Shell#ctime(file)
---- Shell#delete(*file)
---- Shell#dirname(file)
---- Shell#ftype(file)
---- Shell#join(*file)
---- Shell#link(file_from, file_to)
---- Shell#lstat(file)
---- Shell#mtime(file)
---- Shell#readlink(file)
---- Shell#rename(file_from, file_to)
---- Shell#split(file)
---- Shell#stat(file)
---- Shell#symlink(file_from, file_to)
---- Shell#truncate(file, length)
---- Shell#utime(atime, mtime, *file)
-
-      Equivalent to the class methods of File with the same names.

- *  The current implementation of <code>sort_by</code> generates an

- *

- *     Sort by     1.980000   0.040000   2.020000 (  2.013586)
- *     
- *  However, consider the case where comparing the keys is a non-trivial
- *  operation. The following code sorts some files on modification time
- *  using the basic <code>sort</code> method.
- *     
- *     files = Dir["*"]
- *     sorted = files.sort {|a,b| File.new(a).mtime <=> File.new(b).mtime}
- *     sorted   #=> ["mon", "tues", "wed", "thurs"]
- *     
- *  This sort is inefficient: it generates two new <code>File</code>
- *  objects during every comparison. A slightly better technique is to
- *  use the <code>Kernel#test</code> method to generate the modification
- *  times directly.
- *     
- *     files = Dir["*"]
- *     sorted = files.sort { |a,b|
- *       test(?M, a) <=> test(?M, b)
- *     }
- *     sorted   #=> ["mon", "tues", "wed", "thurs"]
- *     
- *  This still generates many unnecessary <code>Time</code> objects. A
- *  more efficient technique is to cache the sort keys (modification
- *  times in this case) before the sort. Perl users often call this
- *  approach a Schwartzian Transform, after Randal Schwartz. We
- *  construct a temporary array, where each element is an array
- *  containing our sort key along with the filename. We sort this array,
- *  and then extract the filename from the result.
- *     
- *     sorted = Dir["*"].collect { |f|
- *        [test(?M, f), f]
- *     }.sort.collect { |f| f[1] }
- *     sorted   #=> ["mon", "tues", "wed", "thurs"]
- *     
- *  This is exactly what <code>sort_by</code> does internally.
- *     
- *     sorted = Dir["*"].sort_by {|f| test(?M, f)}
- *     sorted   #=> ["mon", "tues", "wed", "thurs"]

- *
- * Document-class: UnboundMethod
- *
- *  Ruby supports two forms of objectified methods. Class
- *  <code>Method</code> is used to represent methods that are associated
- *  with a particular object: these method objects are bound to that
- *  object. Bound method objects for an object can be created using
- *  <code>Object#method</code>.
- *     
- *  Ruby also supports unbound methods; methods objects that are not
- *  associated with a particular object. These can be created either by
- *  calling <code>Module#instance_method</code> or by calling
- *  <code>unbind</code> on a bound method object. The result of both of
- *  these is an <code>UnboundMethod</code> object.
- *     
- *  Unbound methods can only be called after they are bound to an
- *  object. That object must be be a kind_of? the method's original
- *  class.
- *

- *     area = area_un.bind(s)
- *     area.call   #=> 144
- *     
- *  Unbound methods are a reference to the method at the time it was
- *  objectified: subsequent changes to the underlying class will not
- *  affect the unbound method.

-= Win32 Registry I/F
-win32/registry is registry accessor library for Win32 platform.
-It uses Win32API to call Win32 Registry APIs.
-
-== example
-  Win32::Registry::HKEY_CURRENT_USER.open('SOFTWARE\foo') do |reg|
-    value = reg['foo']                               # read a value
-    value = reg['foo', Win32::Registry::REG_SZ]      # read a value with type
-    type, value = reg.read('foo')                    # read a value
-    reg['foo'] = 'bar'                               # write a value
-    reg['foo', Win32::Registry::REG_SZ] = 'bar'      # write a value with type
-    reg.write('foo', Win32::Registry::REG_SZ, 'bar') # write a value
-    
-    reg.each_value { |name, type, data| ... }        # Enumerate values
-    reg.each_key { |key, wtime| ... }                # Enumerate subkeys
-    
-    reg.delete_value(name)                         # Delete a value
-    reg.delete_key(name)                           # Delete a subkey
-    reg.delete_key(name, true)                     # Delete a subkey recursively

-=== class methods
---- Registry.open(key, subkey, desired = KEY_READ, opt = REG_OPTION_RESERVED)
---- Registry.open(key, subkey, desired = KEY_READ, opt = REG_OPTION_RESERVED) { |reg| ... }
-    Open the registry key ((|subkey|)) under ((|key|)).
-    ((|key|)) is Win32::Registry object of parent key.
-    You can use predefined key HKEY_* (see ((<constants>)))
-    
-    ((|desired|)) and ((|opt|)) is access mask and key option.
-    For detail, see ((<MSDN Library|URL:http://msdn.microsoft.com/library/en-us/sysinfo/base/regopenkeyex.asp>)).
-    
-    If block is given, the key is closed automatically.
-
---- Registry.create(key, subkey, desired = KEY_ALL_ACCESS, opt = REG_OPTION_RESERVED)
---- Registry.create(key, subkey, desired = KEY_ALL_ACCESS, opt = REG_OPTION_RESERVED) { |reg| ... }
-    Create or open the registry key ((|subkey|)) under ((|key|)).
-    You can use predefined key HKEY_* (see ((<constants>)))
-    
-    If subkey is already exists, key is opened and Registry#((<created?>))
-    method will return false.
-    
-    If block is given, the key is closed automatically.
-
---- Registry.expand_environ(str)
-    Replace (({%\w+%})) into the environment value of ((|str|)).
-    This method is used for REG_EXPAND_SZ.
-    
-    For detail, see ((<ExpandEnvironmentStrings|URL:http://msdn.microsoft.com/library/en-us/sysinfo/base/expandenvironmentstrings.asp>)) Win32 API.
-
---- Registry.type2name(type)
-    Convert registry type value to readable string.
-
---- Registry.wtime2time(wtime)
-    Convert 64-bit FILETIME integer into Time object.
-
---- Registry.time2wtime(time)
-    Convert Time object or Integer object into 64-bit FILETIME.
-
-=== instance methods
---- open(subkey, desired = KEY_READ, opt = REG_OPTION_RESERVED)
-    Same as (({Win32::((<Registry.open>))(self, subkey, desired, opt)}))
-
---- create(subkey, desired = KEY_ALL_ACCESS, opt = REG_OPTION_RESERVED)
-    Same as (({Win32::((<Registry.create>))(self, subkey, desired, opt)}))
-
---- close
-    Close key.
-    
-    After closed, most method raises error.
-
---- read(name, *rtype)
-    Read a registry value named ((|name|)) and return array of
-    [ ((|type|)), ((|data|)) ].
-    When name is nil, the `default' value is read.
-    
-    ((|type|)) is value type. (see ((<Win32::Registry::Constants module>)))
-    ((|data|)) is value data, its class is:
-    :REG_SZ, REG_EXPAND_SZ
-       String
-    :REG_MULTI_SZ
-       Array of String
-    :REG_DWORD, REG_DWORD_BIG_ENDIAN, REG_QWORD
-       Integer
-    :REG_BINARY
-       String (contains binary data)
-    
-    When ((|rtype|)) is specified, the value type must be included by
-    ((|rtype|)) array, or TypeError is raised.
-
---- self[name, *rtype]
-    Read a registry value named ((|name|)) and return its value data.
-    The class of value is same as ((<read>)) method returns.
-    
-    If the value type is REG_EXPAND_SZ, returns value data whose environment
-    variables are replaced.
-    If the value type is neither REG_SZ, REG_MULTI_SZ, REG_DWORD,
-    REG_DWORD_BIG_ENDIAN, nor REG_QWORD, TypeError is raised.
-    
-    The meaning of ((|rtype|)) is same as ((<read>)) method.
-
---- read_s(name)
---- read_i(name)
---- read_bin(name)
-    Read a REG_SZ(read_s), REG_DWORD(read_i), or REG_BINARY(read_bin)
-    registry value named ((|name|)).
-    
-    If the values type does not match, TypeError is raised.
-
---- read_s_expand(name)
-    Read a REG_SZ or REG_EXPAND_SZ registry value named ((|name|)).
-    
-    If the value type is REG_EXPAND_SZ, environment variables are replaced.
-    Unless the value type is REG_SZ or REG_EXPAND_SZ, TypeError is raised.
-
---- write(name, type, data)
-    Write ((|data|)) to a registry value named ((|name|)).
-    When name is nil, write to the `default' value.
-    
-    ((|type|)) is type value. (see ((<Registry::Constants module>)))
-    Class of ((|data|)) must be same as which ((<read>))
-    method returns.
-
---- self[name, wtype = nil] = value
-    Write ((|value|)) to a registry value named ((|name|)).
-    
-    If ((|wtype|)) is specified, the value type is it.
-    Otherwise, the value type is depend on class of ((|value|)):
-    :Integer
-      REG_DWORD
-    :String
-      REG_SZ
-    :Array
-      REG_MULTI_SZ
-
---- write_s(name, value)
---- write_i(name, value)
---- write_bin(name, value)
-    Write ((|value|)) to a registry value named ((|name|)).
-    
-    The value type is REG_SZ(write_s), REG_DWORD(write_i), or
-    REG_BINARY(write_bin).
-
---- each { |name, type, value| ... }
---- each_value { |name, type, value| ... }
-    Enumerate values.
-
---- each_key { |subkey, wtime| ... }
-    Enumerate subkeys.
-    
-    ((|subkey|)) is String which contains name of subkey.
-    ((|wtime|)) is last write time as FILETIME (64-bit integer).
-    (see ((<Registry.wtime2time>)))
-
---- delete(name)
---- delete_value(name)
-    Delete a registry value named ((|name|)).
-    We can not delete the `default' value.
-
---- delete_key(name, recursive = false)
-    Delete a subkey named ((|name|)) and all its values.
-    
-    If ((|recursive|)) is false, the subkey must not have subkeys.
-    Otherwise, this method deletes all subkeys and values recursively.
-
---- flush
-    Write all the attributes into the registry file.
-
---- created?
-    Returns if key is created ((*newly*)).
-    (see ((<Registry.create>)))
-
---- open?
-    Returns if key is not closed.
-
---- hkey

-<H2>Introduction</H2>
-Ruby already has builtin (variable length integer number) class Bignum. Using Bignum class,you can obtain
- any integer value in magnitude. But, variable length decimal number class is not yet built in. 
-This is why I made variable length floating class BigDecimal.
-Feel free to send any comments or bug reports to me.
-<A HREF="mailto:shigeo@tinyforest.gr.jp">shigeo@tinyforest.gr.jp</A>
-I will try(but can't promise) to fix bugs reported. 
-<hr>
-<H2>Installation</H2>
-The Ruby latest version can be downloaded from <A HREF="http://www.ruby-lang.org/en/">Official Ruby page</A>.
-Once decompress the downloaded Ruby archive,follow the normal installation procedures according to the 
-documents included.
-
-<A NAME="#SPEC">
-<H2>Usage and methods</H2>
-Suppose you already know Ruby programming,
-to create BigDecimal objects,the program would like:<BR>
-
-<CODE><PRE>
-   require 'bigdecimal'
-   a=BigDecimal::new("0.123456789123456789")
-   b=BigDecimal("123456.78912345678",40)
-   c=a+b
-</PRE></CODE>
-
-<H3>List of methods</H3>
-In 32 bits integer system,every 4 digits(in decimal) are computed simultaneously.
-This means the number of significant digits in BigDecimal is always a multiple of 4.
-<P>
-Some more methods are available in Ruby code (not C code). 
-Functions such as sin,cos ...,are in math.rb in bigdecimal directory.
-To use them,require math.rb as:
-<CODE><PRE>
-require "bigdecimal/math.rb"
-</PRE></CODE>
-For details,see the math.rb code and comments.
-Other utility methods are in util.rb.
-To use util.rb, require it as:
-<CODE><PRE>
-require "bigdecimal/util.rb"
-</PRE></CODE>
-For details,see the util.rb code.
-
-<H4><U>Class methods</U></H4>
-<UL>
-<LI><B>new</B></LI><BLOCKQUOTE>
-"new" method creates a new BigDecimal object.<BR>
-a=BigDecimal::new(s[,n]) or<BR>
-a=BigDecimal(s[,n]) or<BR>
-where:<BR>
-s: Initial value string. Spaces will be ignored. Any unrecognizable character for 
-representing initial value terminates the string.<BR>
-n: Maximum number of significant digits of a. n must be a Fixnum object.
-If n is omitted or is equal to 0,then the maximum number of significant digits of a is determined from the length of s.
-Actual number of digits handled in computations are usually gretaer than n.<BR>
-n is useful when performing divisions like
-<CODE><PRE>
-BigDecimal("1")    / BigDecimal("3")    # => 0.3333333333 33E0
-BigDecimal("1",10) / BigDecimal("3",10) # => 0.3333333333 3333333333 33333333E0
-</PRE></CODE>
-but the resulting digits obtained may differ in future version.
-</BLOCKQUOTE>

-<LI><B>mode</B></LI><BLOCKQUOTE>
-f = BigDecimal.mode(s[,v])<BR>
-mode method controls BigDecimal computation. If the second argument is not given or is nil,then the value
-of current setting is returned.
-Following usage are defined.<BR>
-<P><B>[EXCEPTION control]</B><P>
-Actions when computation results NaN or Infinity can be defined as follows.
-<P>
-<BLOCKQUOTE>
-f = BigDecimal::mode(BigDecimal::EXCEPTION_NaN,flag)<BR>
-f = BigDecimal::mode(BigDecimal::EXCEPTION_INFINITY,flag)<BR>
-f = BigDecimal::mode(BigDecimal::EXCEPTION_UNDERFLOW,flag)<BR>
-f = BigDecimal::mode(BigDecimal::EXCEPTION_OVERFLOW,flag)<BR>
-f = BigDecimal::mode(BigDecimal::EXCEPTION_ZERODIVIDE,flag)<BR>
-f = BigDecimal::mode(BigDecimal::EXCEPTION_ALL,flag)<BR>
-</BLOCKQUOTE>
-EXCEPTION_NaN controls the execution when computation results to NaN.<BR>
-EXCEPTION_INFINITY controls the execution when computation results to Infinity(�}Infinity).<BR>
-EXCEPTION_UNDERFLOW controls the execution when computation underflows.<BR>
-EXCEPTION_OVERFLOW controls the execution when computation overflows.<BR>
-EXCEPTION_ZERODIVIDE controls the execution when zero-division occures.<BR>
-EXCEPTION_ALL controls the execution for any exception defined occures.<BR>
-If the flag is true,then the relating exception is thrown.<BR>
-No exception is thrown when the flag is false(default) and computation 
-continues with the result:<BR>
-<BLOCKQUOTE>
-EXCEPTION_NaN results to NaN<BR>
-EXCEPTION_INFINITY results to +Infinity or -Infinity<BR>
-EXCEPTION_UNDERFLOW results to 0.<BR>
-EXCEPTION_OVERFLOW results to +Infinity or -Infinity<BR>
-EXCEPTION_ZERODIVIDE results to +Infinity or -Infinity<BR>
-</BLOCKQUOTE>
-EXCEPTION_INFINITY,EXCEPTION_OVERFLOW, and EXCEPTION_ZERODIVIDE are
- currently the same.<BR>
-The return value of mode method is the value set.<BR>
-If nil is specified for the second argument,then current setting is returned.<BR>
-Suppose the return value of the mode method is f,then 
- f &amp; BigDecimal::EXCEPTION_NaN !=0 means EXCEPTION_NaN is set to on.
-<P>
-<B>[ROUND error control]</B><P>
-Rounding operation can be controlled as:
-<BLOCKQUOTE>
-f = BigDecimal::mode(BigDecimal::ROUND_MODE,flag)
-</BLOCKQUOTE>
-where flag must be one of:
-<TABLE>
-
-<TR><TD>ROUND_UP</TD><TD>round away from zero.</TD></TR>
-<TR><TD>ROUND_DOWN</TD><TD>round towards zero(truncate).</TD></TR>
-<TR><TD>ROUND_HALF_UP</TD><TD>round up if the digit &gt;= 5 otherwise truncated(default).</TD></TR>
-<TR><TD>ROUND_HALF_DOWN</TD><TD>round up if the digit &gt;= 6 otherwise truncated.</TD></TR>
-<TR><TD>ROUND_HALF_EVEN</TD><TD>round towards the even neighbor(Banker's rounding).
-<TR><TD>ROUND_CEILING</TD><TD>round towards positive infinity(ceil).</TD></TR>
-<TR><TD>ROUND_FLOOR</TD><TD>round towards negative infinity(floor).</TD></TR>
-</TABLE>
-New rounding mode is returned. If nil is specified for the second argument,then current setting is returned.<BR>
-The digit location for rounding operation can not be specified by this mode method,
-use truncate/round/ceil/floor/add/sub/mult/div mthods for each instance instead.
-</BLOCKQUOTE>
-
-<LI><B>limit[(n)]</B></LI><BLOCKQUOTE>
-Limits the maximum digits that the newly created BigDecimal objects can hold never exceed n.
-This means the rounding operation specified by BigDecimal.mode is 
-performed if necessary.
-limit returns the value before set if n is nil or is not specified.
-Zero,the default value,means no upper limit.<BR>
-The limit has no more priority than instance methods such as truncate,round,ceil,floor,add,sub,mult,and div. <BR>
-mf = BigDecimal::limit(n)<BR>
-</BLOCKQUOTE>

-<H3>About 'coerce'</H3>
-<B>For the binary operation like A op B:</B>
-<DL>
-<DT> 1.Both A and B are BigDecimal objects</DT>
-<DD> A op B is normally performed.</DD>
-<DT> 2.A is the BigDecimal object but B is other than BigDecimal object</DT>
-<DD> Operation is performed,after B is translated to correcponding BigDecimal object(because BigDecimal supports coerce method).</DD>
-<DT> 3.A is not the BigDecimal object but B is BigDecimal object</DT>
-<DD>If A has coerce mthod,then B will translate A to corresponding 
-BigDecimal object and the operation is performed,otherwise an error occures.</DD>
-</DL>
-
-String is not translated to BigDecimal in default.
-Uncomment /* #define ENABLE_NUMERIC_STRING */ in bigdecimal.c, compile and install 
-again if you want to enable string to BigDecimal conversion.
-Translation stops without error at the character representing non digit.
-For instance,"10XX" is translated to 10,"XXXX" is translated to 0.<BR>
-String representing zero or infinity such as "Infinity","+Infinity","-Infinity",and "NaN" can also be translated to BigDecimal unless false is specified by mode method.<BR>
-
-BigDecimal class supports coerce method(for the details about coerce method,see Ruby documentations). This means the most binary operation can be performed if the BigDecimal object is at the left hand side of the operation.<BR><BR>
-
- For example:
-<CODE><PRE>
-  a = BigDecimal.E(20)
-  c = a * "0.123456789123456789123456789" # A String is changed to BigDecimal object.
-</PRE></CODE>
-is performed normally.<BR>
- But,because String does not have coerce method,the following example can not be performed.<BR>
-
-<CODE><PRE>
-  a = BigDecimal.E(20)
-  c = "0.123456789123456789123456789" * a # ERROR
-</PRE></CODE>
-
-If you actually have any inconvenience about the error above.
-You can define a new class derived from String class,
-and define coerce method within the new class.<BR>

-If the internal representation is binary,translation from decimal to 
-binary is required and the translation error is inevitable.

-0.1 => b1*2**(-1)+b1*2**(-2)+b3*2**(-3)+b4*2**(-4)....<BR>

-Of cource,exact "0.1" is printed if the rouding operation is properly done,
-<DT>Significant digit we can have is automatically determined
-<DD>In binary representation,0.1 can not be represented in finite series of digit.
-
-But we only need one element(frac[0]=1) in decimal representation.
-This means that we can always determine the size of the array frac[] in Real 
-structure.

-
-<H3>Disadvantage of decimal representation</H3>
-Advantages stated so far can also be disadvantages if the input from outside is
- represented in binary.
-Translation error from decimal to binary or vice versa is inevitable.
-So,translation from Float(binary) to BigDecimal(decimal) is not alway done exactly.

-** MD5(Class)
-
-A class to implement the MD5 Message-Digest Algorithm by RSA Data
-Security, Inc., described in RFC1321.
-
-Superclass: Digest::Base
-
-require 'digest/md5'
-
-** SHA1(Class)
-
-A class to implement the SHA-1 Secure Hash Algorithm by NIST (the US'
-National Institute of Standards and Technology), described in FIPS PUB
-180-1.
-
-Superclass: Digest::Base
-
-require 'digest/sha1'
-
-** SHA256(Class)
-** SHA384(Class)
-** SHA512(Class)
-
-Classes to implement the SHA-256/384/512 Secure Hash Algorithm(s) by
-NIST (the US' National Institute of Standards and Technology),
-described in FIPS PUB 180-2.
-
-Superclass: Digest::Base
-
-require 'digest/sha2'
-
-** RMD160(Class)
-
-A class to implement the RIPEMD-160 cryptographic hash function,
-designed by Hans Dobbertin, Antoon Bosselaers, and Bart Preneel.
-
-Superclass: Digest::Base
-
-require 'digest/rmd160'
-
-
-Those above classes provide a common interface as shown below.
-
-
-Class Methods:
-
-   new([str])
-
-	Creates a new digest object.  If a string argument is given,
-	it is added to the object. (see update.)
-
-   digest(str)
-
-	Immediately calculates and return the hash of the given
-	strings as a string.  Equivalent to new(str).digest.
-
-   hexdigest(str)
-
-	Immediately calculates and return the hash of the given
-	strings as a string of hexadecimal digits.  Equivalent to
-	new(str).hexdigest.
-
-Methods:
-
-   clone
-
-	Creates a copy of the digest object.
-
-   digest
-
-	Returns the hash of the added strings as a string of 16 bytes
-	for MD5, 20 bytes for SHA1 and RMD160, 32 bytes for SHA256, 48
-	bytes for SHA384, and 64 bytes for SHA512.
-
-   hexdigest
-   to_s
-
-	Returns the hash of the added strings as a string of 32
-	hexadecimal digits for MD5, 40 hexadecimal digits for SHA1 and
-	RMD160, 64 hexadecimal digits for SHA256, 96 hexadecimal
-	digits for SHA384, and 128 hexadecimal digits for SHA512.
-	This method is equal to:
-
-	def hexdigest
-	  digest.unpack("H*")[0]
-	end
-
-   update(str)
-   << str
-
-	Appends the string str to the digest object.  Repeated calls
-	are equivalent to a single call with the concatenation of all
-	the arguments, i.e. m.update(a); m.update(b) is equivalent to
-	m.update(a + b) and m << a << b is equivalent to m << a + b.
-
-   == md
-
-	Checks if the object is equal to the given digest object.
-
-   == str
-
-	Regards the value as either a digest value or a hexdigest
-	value (depending on the length) and checks if the object is
-	equal to the given string.

-		made test program self-checking.
-  1999-11-04 lpd Edited comments slightly for automatic TOC extraction.
-  1999-10-18 lpd Fixed typo in header comment (ansi2knr rather than md5).

-
-= Ruby/DL
-
-Ruby/DL provides an interface to the dynamic linker such as dlopen() on UNIX
-and LoadLibrary() on Windows.
-
-= Building and Installing
-
-  $ ruby extconf.rb    # to create the Makefile
-  $ make               # to build the library 'dl.so'
-  $ make libtest.so    # to build the C library 'libtest.so' for the test script
-  $ make test          # to run the test script
-  $ make install       # to install the library
-  $ make clean         # to remove the created files without Makefile
-  $ make distclean     # to remove the all created files
-
-= Using Ruby/DL
-
-We should usually use DL::Importable module provided by "dl/import.rb".
-It has high-level functions to access library functions. We use
-DL::Importable module to extend a module as follows:
-
-  require "dl/import"
-  module LIBC
-    extend DL::Importable
-  end
-
-Now we can use methods dlload and extern in this module. We load the
-libraries using dlload, and define wrapper methods to library functions
-using extern respectively as follows:
-
-  module LIBC
-    extend DL::Importable
-    dlload "libc.so.6","libm.so.6"
-    extern "int strlen(char*)"
-  end
-  # Note that we should not include the module LIBC from some reason.
-
-We can call the library function strlen() using LIBC.strlen. If the first
-character of given function name is an uppercase, the first character of the
-defined method name becomes lowercase.
-We can also construct memory images of structures and unions using functions
-struct and union which are defined in "dl/struct.rb" as follows:
-
-  require "dl/import"
-  require "dl/struct"
-  module LIBC
-    extend DL::Importable
-    Timeval = struct [       # define timeval structure.
-      "long tv_sec",
-      "long tv_uses",
-    ]
-  end
-  val = LIBC::Timeval.malloc # allocate memory.
-
-Notice that the above example takes LIBC::Timeval.malloc to allocate memory,
-rather than LIBC::Timeval.new. It is because DL::Timeval.new is for wrapping
-an object, PtrData, which has already been created.
-
-We can define a callback using the module function "callback" as follows:
-
-  module Foo
-    extend DL::Importable
-    def my_comp(str1,str2)
-      str1 <=> str2
-    end
-    COMPARE = callback "int my_comp(char*,char*)"
-  end
-
-where Foo::COMPARE is a Symbol object which invokes the method "my_comp".
-
-DL::Importable module is very useful. However, we sometimes encounter a case
-that we must directly use low-level functions such as dlsym(). In such case,
-we would use DL module functions. They are described in next section.
-
-= DL module
-
-Module DL consists of three classes, a few module functions and constants.
-The class Symbol represents the symbol we can call. The class PtrData
-indicates a memory block such as a pointer in C. An object instantiated from
-the class Handle keeps a handle to opened library.
-
-== Constants
-
-* VERSION
-* MAJOR_VERSION
-* MINOR_VERSION
-* PATCH_VERSION
-* RTLD_GLOBAL
-* RTLD_LAZY
-* RTLD_NOW
-* MAX_ARG
-* MAX_CBARG
-* MAX_CBENT
-
-== Functions
-
-* handle = dlopen(lib){|handle| ... }
-  * is quite equal to `Handle.new(lib)'
-
-* sym = set_callback(cbtype, entry){|args| ... }
-* sym = set_callback(cbtype, entry, proc)
-  * makes entry-th pre-defined function to call the proc or given block. the 
-    entry-th pre-defined function is specified by cbtype and entry. cbtype is a
-    prototype of the callback. see also the section `Type specifiers' about 
-    cbtype.
-
-* sym = get_callback(cbtype, entry)
-  * returns the Proc object which is given by the above function
-   `set_callback'.
-
-* ptr = malloc(size, [free = nil])
-  * allocates the size bytes, and returns the pointer as a PtrData object ptr.
-
-* ptr = strdup(str)
-  * returns a PtrData object ptr which represents the pointer to a new string
-    which is a duplicate of the string str.
-
-* size = sizeof(type)
-  * returns the size of type. `sizeof("C") + sizeof("L")' is not equal to
-    `sizeof("CL")'. the latter is assumed to returns the enough size of the
-    structure `struct foo { char c; long l; }', but the size may not equal to
-    `sizeof(foo)' of C.
-
-== Handle class
-
-* handle = Handle.new(lib){|handle| ... }
-  * opens a library lib and returns a Handle object handle. if a block is
-    given, the handle is automatically closed as the block ends.
-
-* Handle#close
-  * closes the handle opened by the above Handle.new(lib).
-
-* sym = Handle#sym(func, prototype = "0"),
-  sym = Handle#[func, prototype = nil]
-
-  * obtains the pointer to a function called func and returns a Symbol object
-    or a DataPtr object. prototype is a string which consists of type
-    specifiers, it indicates the function's prototype. see also the section
-    `Type specifiers'.
-
-== Symbol class
-
-* sym = Symbol.new(addr, type = nil, name = nil)
-  * creates the Symbol object sym with the type type if type is not nil. addr
-    is the address where the function is allocated. If type is nil, it returns
-    a DataPtr object.
-
-* Symbol::char2type(char)
-  * takes a character char that represents a type and returns the type
-    specifier of the C language.
-
-* str = Symbol#proto()
-  * returns the function prototype.
-
-* str = Symbol#name()
-  * Returns the function name.
-
-* str = Symbol#cproto(),
-  str = Symbol#to_s()
-  * returns the prototype of the C language.
-
-* str = Symbol#inspect()
-  * returns the inspectable string.
-
-* r,rs = Symbol#call(arg1,arg2,...,argN),
-  r,rs = Symbol#[](arg1,arg2,...,argN)
-  * calls the function with parameters arg1, arg2, ..., argN. and the result
-    consists of the return value r and parameters rs. rs is an array.
-
-* ptr = Symbol#to_ptr
-  * returns the corresponding PtrData object ptr.
-
-== PtrData class
-
-* ptr = PtrData.new(addr, [size = 0, free = nil])
-  * returns the PtrData object representing the pointer which indicates the
-    address addr. GC frees the memory using the free function.
-
-* PtrData#free=(sym)
-  * If you specify a symbol object sym, GC frees the memory using the function
-    represented by sym.
-
-* sym = PtrData#free
-  * returns a symbol object sym which is used when GC frees the memory. it
-    usually configured by `PtrData#free=' or `PtrData.new'.
-
-* size = PtrData#size, PtrData#size=(size)
-  * gets and sets allocated size of the memory.
-
-* ary = PtrData#to_a(type, [size])
-  * returns an array of the type which specified with type. type must be one of
-    'S','P','I','L','D' and 'F'.
-
-* str = PtrData#to_s([len])
-  * returns a string which length is len. if len is omitted, the end of the
-    string is '\0'.
-
-* ptr = PtrData#ptr,+@
-  * returns the pointed value as a PtrData object ptr.
-
-* ptr = PtrData#ref,-@
-  * returns the reference as a PtrData object ptr.
-
-* ptr = PtrData#+
-  * returns the PtrData object
-
-* ptr = PtrData#-
-  * returns the PtrData object
-
-* PtrData#struct!(type, *members)
-  * defines the data type to get access to a structure member with a symbol.
-    (see also PtrData#[])
-
-* PtrData#union!(type, *members)
-  * defines the data type to get access to a union member with a symbol. (see
-    also PtrData#[])
-
-* val = PtrData#[key], PtrData#[key, num = 0]
-  * if the key is a string or symbol, this method returns the value of the
-    structure/union member which has the type defined by PtrData#
-    {struct!,union!}. if the key is a integer value and this object represents
-    the pointer ptr, it returns the value of `(ptr + key).to_s(num)'
-
-* PtrData#[key,num]=val, PtrData#[key]=val
-  * if the key is a string or symbol, this method substitute the value of the
-    structure/union member with val. if the key is a integer value and val is a
-    string, this method copies num bytes of val to the memory area ptr using
-    memcpy(3).
-
-== Type specifiers
-
-the prototype consists of the following type specifiers, first element of 
-prototype represents the type of return value, and remaining elements represent
-the type of each argument.
-
-    C : char
-    c : char *
-    H : short
-    h : short *
-    I : int
-    i : int *
-    L : long
-    l : long *
-    F : float
-    f : float *
-    D : double
-    d : double *
-    S : const char *
-    s : char *
-    A : const type[]
-    a : type[] (allocates new memory space)
-    P : void * (same as 'p')
-    p : void * (same as 'P')
-    0 : void function (this must be a first character of the prototype)
-
-the cbtype consists of type specifiers 0, C, I, H, L, F, D, S and P.
-for example:
-
-    DL.callback('IPP'){|ptr1,ptr2|
-      str1 = ptr1.ptr.to_s
-      str2 = ptr2.ptr.to_s
-      str1 <=> str2
-    }

-** Enumerable::Enumerator(Class)
-
-A class which provides a method `each' to be used as an Enumerable
-object.
-
-Superclass: Object
-
-Mix-ins: Enumerable
-
-require 'enumerator'
-
-Class Methods:
-
-    new(obj, method = :each, *args)
-
-	Creates a new Enumerable::Enumerator object, which is to be
-	used as an Enumerable object using the given object's given
-	method with the given arguments.
-
-	e.g.:
-	    str = "xyz"
-
-	    enum = Enumerable::Enumerator.new(str, :each_byte)
-	    a = enum.map {|b| '%02x' % b } #=> ["78", "79", "7a"]
-
-Methods:
-
-    each {...}
-
-	Iterates the given block using the object and the method
-	specified in the first place.
-
-
-Requiring this module also adds some methods to the Object class:
-
-    to_enum(method = :each, *args)
-    enum_for(method = :each, *args)
-
-	Returns Enumerable::Enumerator.new(self, method, *args).
-
-	e.g.:
-	    str = "xyz"
-
-	    enum = str.enum_for(:each_byte)
-	    a = enum.map {|b| '%02x' % b } #=> ["78", "79", "7a"]
-
-	    # protects an array from being modified
-	    a = [1, 2, 3]
-	    some_method(a.to_enum)
-
-And the Enumerable module.
-
-    each_slice(n) {...}
-
-	Iterates the given block for each slice of <n> elements.
-
-	e.g.:
-	    (1..10).each_slice(3) {|a| p a}
-	    # outputs below
-	    [1, 2, 3]
-	    [4, 5, 6]
-	    [7, 8, 9]
-	    [10]
-
-    enum_slice(n)
-
-	Returns Enumerable::Enumerator.new(self, :each_slice, n).
-
-    each_cons(n) {...}
-
-	Iterates the given block for each array of consecutive <n>
-	elements.
-
-	e.g.:
-	    (1..10).each_cons(3) {|a| p a}
-	    # outputs below
-	    [1, 2, 3]
-	    [2, 3, 4]
-	    [3, 4, 5]
-	    [4, 5, 6]
-	    [5, 6, 7]
-	    [6, 7, 8]
-	    [7, 8, 9]
-	    [8, 9, 10]
-
-    enum_cons(n)
-
-	Returns Enumerable::Enumerator.new(self, :each_cons, n).
-
-    enum_with_index
-
-	Returns Enumerable::Enumerator.new(self, :each_with_index).

-** Etc(Module)
-
-The module to retrieve information under /etc directory.  Available
-only on UNIX platforms.  All operations defined in this module are
-module functions, so that you can include Etc module into your class.
-
-Module Function:
-
-   getlogin
-
-	returns login name of the user.  It this fails, try getpwuid().
-
-   getpwnam(name)
-
-	searches in /etc/passwd file (or equivalent database), and
-	returns password entry for the user.  The return value is an
-	passwd structure, which has members described below.
-
-	  struct passwd
-	    name 	# user name(string)
-	    passwd	# encrypted password(string)
-	    uid		# user ID(integer)
-	    gid		# group ID(integer)
-	    gecos	# gecos field(string)
-	    dir		# home directory(string)
-	    shell	# login shell(string)
-	    # members below are optional
-	    change	# password change time(integer)
-	    quota	# quota value(integer)
-	    age		# password age(integer)
-	    class	# user access class(string)
-	    comment	# comment(string)
-	    expire	# account expiration time(integer)	    
-	  end
-
-	See getpwnam(3) for detail.
-
-   getpwuid([uid])
-
-	returns passwd entry for the specified user id.  If uid is
-	ommitted, use the value from getuid().  See getpwuid(3) for
-	detail.
-
-   getgrgid(gid)
-
-	searches in /etc/group file (or equivalent database), and
-	returns group entry for the group id.  The return value is an
-	group structure, which has members described below.
-
-	  struct group
-	    name 	# group name(string)
-	    passwd	# group password(string)
-	    gid		# group ID(integer)

- * 
- * Which coding systems are available is platform-dependent.
- * 
- * == Examples
- *
- * 1. Instantiate a new Iconv and use method Iconv#iconv.
- *
- *      cd = Iconv.new(to, from)
- *      begin
- *        input.each { |s| output << cd.iconv(s) }
- *        output << cd.iconv(nil)                   # Don't forget this!
- *      ensure
- *        cd.close
- *      end
- *
- * 2. Invoke Iconv.open with a block.
- *
- *      Iconv.open(to, from) do |cd|
- *        input.each { |s| output << cd.iconv(s) }
- *        output << cd.iconv(nil)
- *      end
- *
- * 3. Shorthand for (2).
- *
- *      Iconv.iconv(to, from, *input.to_a)
- *
- * 4. Simple conversion between two charsets.
- *
- *      converted_text = Iconv.new('iso-8859-15', 'utf-8').iconv(text)

-== class Net::HTTP
-
-== Example
-
-Simple HTTP client is here:
-
-    require 'net/http'
-    host, port, path = "localhost", 80, "/"
-    if %r!http://(.*?)(?::(\d+))?(/.*)! =~ ARGV[0]
-      host   = $1
-      port   = $2.to_i if $2
-      path   = $3
-    end
-    h = Net::HTTP.new(host, port)
-    h.get2(path){ |resp| print resp.body }
-
-It can be replaced by follow one:
-
-    require 'net/https'
-    host, port, path = "localhost", 80, "/"
-    if %r!(https?)://(.*?)(?::(\d+))?(/.*)! =~ ARGV[0]
-      scheme = $1
-      host   = $2
-      port   = $3 ? $3.to_i : ((scheme == "http") ? 80 : 443)
-      path   = $4
-    end
-    h = Net::HTTP.new(host, port)
-    h.use_ssl = true if scheme == "https" # enable SSL/TLS
-    h.get2(path){ |resp| print resp.body }
-
-=== Instance Methods
-
-: use_ssl
-    returns ture if use SSL/TLS with HTTP.
-
-: use_ssl=((|true_or_false|))
-    sets use_ssl.
-
-: peer_cert
-    return the X.509 certificates the server presented.
-
-: key=((|key|))
-    Sets an OpenSSL::PKey::RSA or OpenSSL::PKey::DSA object.
-    (This method is appeared in Michal Rokos's OpenSSL extention.)
-
-: key_file=((|path|))
-    Sets a private key file to use in PEM format.
-
-: cert=((|cert|))
-    Sets an OpenSSL::X509::Certificate object as client certificate.
-    (This method is appeared in Michal Rokos's OpenSSL extention.)
-
-: cert_file=((|path|))
-    Sets pathname of a X.509 certification file in PEM format.
-
-: ca_file=((|path|))
-    Sets path of a CA certification file in PEM format.
-    The file can contrain several CA certificats.
-
-: ca_path=((|path|))
-    Sets path of a CA certification directory containing certifications
-    in PEM format.
-
-: verify_mode=((|mode|))
-    Sets the flags for server the certification verification at
-    begining of SSL/TLS session.
-    OpenSSL::SSL::VERIFY_NONE or OpenSSL::SSL::VERIFY_PEER is acceptable.
-
-: verify_callback=((|proc|))
-    Sets the verify callback for the server certification verification.
-
-: verify_depth=((|num|))
-    Sets the maximum depth for the certificate chain verification.
-
-: cert_store=((|store|))
-    Sets the X509::Store to verify peer certificate.

-pty extension version 0.3 by A.ito
-
-1. Introduction
-
-This extension module adds ruby a functionality to execute an 
-arbitrary command through pseudo tty (pty).
-
-2. Install
-
-Follow the instruction below.
-
-(1) Execute
-
-      ruby extconf.rb
-
-    then Makefile is generated.
-
-(3) Do make; make install.
-
-3. What you can do
-
-This extension module defines a module named PTY, which contains
-following module fungtions:
-
-   getpty(command)
-   spawn(command)
-
-      This function reserves a pty, executes command over the pty 
-      and returns an array. The return value is an array with three
-      elements. The first element in the array is for reading and the 
-      second for writing. The third element is the process ID of the
-      child process. If this function is called with an iterator block,
-      the array is passed to the block as block parameters, and the
-      function itself returns nil.
-
-      When the child process is suspended or finished, an exception is
-      raised.  If this function is called with an iterator block,
-      exception is raised only within the block.  Child process
-      monitor is terminated on block exit.
-
-   protect_signal
-   reset_signal
-
-      These functions are obsolete in this version of pty.

-	README for expect
-		by A. Ito, 28 October, 1998
-
-	Expect library adds IO class a method called expect(), which
-does similar act to tcl's expect extension. 
-
-The usage of the method is:
-
-   IO#expect(pattern,timeout=9999999)
-
-where `pattern' is an instance of String or Regexp and `timeout'
-is Fixnum, which can be omitted. 
-	When the method is called without block, it waits until the
-input which matches the pattern is obtained from the IO or the time
-specified as the timeout passes. When the pattern is obtained from the
-IO, the method returns an array. The first element of the array is the
-entire string obtained from the IO until the pattern matches. The
-following elements indicates the specific pattern which matched to the
-anchor in the regular expression. If the method ends because of
-timeout, it returns nil. 
- 	When the method is called with block, the array is passed as
-the block parameter.

-= Differences to (({IO}))
-
-* not implemented: (({fcntl})), (({reopen})).
-* (({fileno})) returns nil.

- * Document-class: StringScanner
- * 
- * StringScanner provides for lexical scanning operations on a String.  Here is
- * an example of its usage:
- *
- *   s = StringScanner.new('This is an example string')
- *   s.eos?               # -> false
- *   
- *   p s.scan(/\w+/)      # -> "This"
- *   p s.scan(/\w+/)      # -> nil
- *   p s.scan(/\s+/)      # -> " "
- *   p s.scan(/\s+/)      # -> nil
- *   p s.scan(/\w+/)      # -> "is"
- *   s.eos?               # -> false
- *   
- *   p s.scan(/\s+/)      # -> " "
- *   p s.scan(/\w+/)      # -> "an"
- *   p s.scan(/\s+/)      # -> " "
- *   p s.scan(/\w+/)      # -> "example"
- *   p s.scan(/\s+/)      # -> " "
- *   p s.scan(/\w+/)      # -> "string"
- *   s.eos?               # -> true
- *   
- *   p s.scan(/\s+/)      # -> nil
- *   p s.scan(/\w+/)      # -> nil
- *
- * Scanning a string means remembering the position of a <i>scan pointer</i>,
- * which is just an index.  The point of scanning is to move forward a bit at
- * a time, so matches are sought after the scan pointer; usually immediately
- * after it.
- *
- * Given the string "test string", here are the pertinent scan pointer
- * positions:
- *
- *     t e s t   s t r i n g
- *   0 1 2 ...             1
- *                         0
- *
- * When you #scan for a pattern (a regular expression), the match must occur
- * at the character after the scan pointer.  If you use #scan_until, then the
- * match can occur anywhere after the scan pointer.  In both cases, the scan
- * pointer moves <i>just beyond</i> the last character of the match, ready to
- * scan again from the next character onwards.  This is demonstrated by the
- * example above.
- *
- * == Method Categories
- *
- * There are other methods besides the plain scanners.  You can look ahead in
- * the string without actually scanning.  You can access the most recent match.
- * You can modify the string being scanned, reset or terminate the scanner,
- * find out or change the position of the scan pointer, skip ahead, and so on.
- * 
- * === Advancing the Scan Pointer
- *
- * - #getch
- * - #getbyte
- * - #scan
- * - #scan_until
- * - #skip
- * - #skip_until
- *
- * === Looking Ahead
- *
- * - #check
- * - #check_until
- * - #exist?
- * - #match?
- * - #peek
- *
- * === Finding Where we Are
- *
- * - #bol?
- * - #eos?
- * - #rest?
- * - #rest_size
- * - #pos
- *
- * === Setting Where we Are
- *
- * - #reset
- * - #terminate
- * - #pos=
- * 
- * === Match Data
- *
- * - #matched
- * - #matched?
- * - #matched_size
- * - []
- * - #pre_match
- * - #post_match
- *
- * === Miscellaneous
- *
- * - <<
- * - #concat
- * - #string
- * - #string=
- * - #unscan
- *
- * There are aliases to several of the methods.

-UNIX Syslog extension for Ruby
-Amos Gouaux, University of Texas at Dallas
-<amos+ruby@utdallas.edu>
-&
-Akinori MUSHA
-<knu@ruby-lang.org>
-
-** Syslog(Module)
-
-Included Modules: Syslog::Constants
-
-require 'syslog'
-
-A Simple wrapper for the UNIX syslog system calls that might be handy
-if you're writing a server in Ruby.  For the details of the syslog(8)
-architecture and constants, see the syslog(3) manual page of your
-platform.
-
-Module Methods:
-
-   open(ident = $0, logopt = Syslog::LOG_PID | Syslog::LOG_CONS,
-		facility = Syslog::LOG_USER) [{ |syslog| ... }]
-
-	Opens syslog with the given options and returns the module
-	itself.  If a block is given, calls it with an argument of
-	itself.  If syslog is already opened, raises RuntimeError.
-
-	Example:
-	  Syslog.open('ftpd', Syslog::LOG_PID | Syslog::LOG_NDELAY,
-			      Syslog::LOG_FTP)
-
-   open!(ident = $0, logopt = Syslog::LOG_PID | Syslog::LOG_CONS,
-		facility = Syslog::LOG_USER)
-   reopen(ident = $0, logopt = Syslog::LOG_PID | Syslog::LOG_CONS,
-		facility = Syslog::LOG_USER)
-
-	Same as open, but does a close first.
-
-   opened?
-
-	Returns true if syslog opened, otherwise false.
-
-   ident
-   options
-   facility
-
-	Returns the parameters given in the last open, respectively.
-	Every call of Syslog::open resets these values.
-
-   log(pri, message, ...)
-
-	Writes message to syslog.
-
-	Example:
-	  Syslog.log(Syslog::LOG_CRIT, "the sky is falling in %d seconds!", 10)
-
-   crit(message, ...)
-   emerg(message, ...)
-   alert(message, ...)
-   err(message, ...)
-   warning(message, ...)
-   notice(message, ...)
-   info(message, ...)
-   debug(message, ...)
-
-	These are shortcut methods of Syslog::log().  The lineup may
-	vary depending on what priorities are defined on your system.
-
-	Example:
-	  Syslog.crit("the sky is falling in %d seconds!", 5)
- 
-   mask
-   mask=(mask)
-
-	Returns or sets the log priority mask.  The value of the mask
-	is persistent and will not be reset by Syslog::open or
-	Syslog::close.
-
-	Example:
-	  Syslog.mask = Syslog::LOG_UPTO(Syslog::LOG_ERR)
-
-   close 
-
-	Closes syslog.
-
-   inspect
-
-	Returns the "inspect" string of the Syslog module.
-
-   instance
-
-	Returns the module itself. (Just for backward compatibility)
-
-   LOG_MASK(pri)
-
-	Creates a mask for one priority.
-
-   LOG_UPTO(pri)
-
-	Creates a mask for all priorities up to pri.
-
-** Syslog::Constants(Module)
-
-require 'syslog'
-include Syslog::Constants
-
-This module includes the LOG_* constants available on the system.
-
-Module Methods:
-
-   LOG_MASK(pri)
-
-	Creates a mask for one priority.
-
-   LOG_UPTO(pri)
-
-	Creates a mask for all priorities up to pri.

-This document discribes about the 'tcltklib' library. Although there
-is the 'tcltk' library (tcltk.rb) under this directory, no description
-in this document (because it is not maintained recently). 
-
-==============================================================
-module TclTklib
-  : Defines methods to do operations which are independed on 
-  : Tcl/Tk interpreters
-
-  module TclTkLib::EventFlag
-    : Defines flags to define taget events on 'do_one_event' methos. 
-    : When to give, please use bit-operator (e.g. WINDOW | DONT_WAIT). 
-
-    [constants]
-       NONE
-         : Is 0. It means "there is no target". But on the real
-         : operation, it is same to ALL.
-
-       WINDOW
-         : 'window' event is processed.
-
-       FILE
-         : 'file' event is processed.
-
-       TIMER
-         : 'timer' event is processed.
-
-       IDLE
-         : 'idle' operation (e.g. 're-draw'; the operations when the
-         : other kinds of events doesn't occur) is processed. 
-
-       ALL
-         : All kinds of events are processed. 
-         : Same to 'WINDOW | FILE | TIMER | IDLE'. 
-
-       DONT_WAIT
-         : Without this flag, 'do_one_event' waits the occurence of 
-         : a target event. With this flag, doesn't wait and returns 
-         : false if there is no target event for processing. 
-
-  module TclTkLib::VarAccessFlag
-    : Defines flags to give '_get_variable' and so on. When to give, 
-    : please use bit-operator (e.g. GLOBAL_ONLY | LEAVE_ERR_MSG ). 
-
-    [constants]
-       NONE

-         : Under normal circumstances the procedures look up 
-         : variables as follows: If a procedure call is active

-         : in flags then the variable is looked up only in the
-         : global namespace even if there is a procedure call
-         : active. If both GLOBAL_ONLY and NAMESPACE_ONLY are
-         : given, GLOBAL_ONLY is ignored.

-         : (site Tcl/Tk's man page)
-         : If an error is returned and this bit is set in flags,

-         : (site Tcl/Tk's man page)
-         : If this bit is set then newValue is appended to the

-         : If this bit is set when calling _set_variable and so

-         : element name: if the name contains an open parenthesis 
-         : and ends with a close parenthesis, then the value 
-         : between the parentheses is treated as an element name 
-         : (which can have any string value) and the characters
-         : before  the first open parenthesis are treated as the 
-         : name of an array variable. If the flag PARSE_VARNAME
-         : is given, index_name argument should be 'nil' since the 
-         : array and element names are taken from var_name.
-         :

-To compile 'tcltklib', you must have Tcl/Tk libraries on your environment. 
-Although 'extconf.rb' script searches Tcl/Tk libraries and header files, 
-sometimes fails to find them. And then, 'tcltklib' cannot be compiled. If 
-Tcl/Tk libraries or header files are installed but are not found, you can 
-give the information by arguments of the 'configure' script. Please give 
-some or all of the following options. 
-
- --with-tcllib=<libname>    (e.g. libtcl8.3.so ==> --with-tcllib=tcl8.3)
- --with-tklib=<libname>     (e.g. libtk8.3.so  ==> --with-tklib=tk8.3)
-
- --enable-tcltk_stubs       (if you force to enable stubs)
-
- --with-tcl-dir=<path> 
-      equal to "--with-tcl-include=<path>/include --with-tcl-lib=<path>/lib"
-
- --with-tk-dir=<path> 
-      equal to "--with-tk-include=<path>/include --with-tk-lib=<path>/lib"

- --with-tcl-lib=<dir>       the directry containts 'libtcl<version>.so'
- --with-tk-lib=<dir>        the directry containts 'libtk<version>.so'
-
-If you forgot to give the options when do 'configure' on toplevel
-directry of Ruby sources, please try something like as the followings.
-
- $ cd ext/tcltklib
- $ rm Makefile
- $ CONFIGURE_ARGS='--with-tcl-include=/usr/local/include/tcl8.3/ --with-tcllib=tcl8.3 --with-tklib=tk8.3 --enable-tcltk_stubs' ruby extconf.rb
-
-
- *** ATTENTION ***
-When your Tcl/Tk libraries are compiled with "pthread support", 
-Ruby/Tk may cause "Hang-up" or "Segmentation Fault" frequently. 
-If you have such a trouble, please try to use the '--enable-pthread' 
-option of the 'configure' command and re-compile Ruby sources. 
-It may help you to avoid this trouble. The following configure 
-options may be useful.
-
-  --enable-tcl-thread/--disable-tcl-thread
-  --with-tclConfig-file=<path of 'tclConfig.sh'>
-
-It is not need that 'tclConfig.sh' is a normal Tcl/Tk's tclConfig.sh. 
-But the file is expected to include the line "TCL_THREADS=0" or "...=1".
-When no "TCL_THREADS=?" line, if Tcl version is 7.x or 8.0 which is 
-given by "TCL_MAJOR_VERSION=?" line and "TCL_MINOR_VERSION=?" line, 
-then --disable-tcl-thread is expected. Else, ignore the 'tclConfig.sh'.
-If --enable-tcl-thread or --disable-tcl-thread option is given, then 
---with-tclConfig-file option is ignored.

-ActiveTcl is ActiveState's quality-assured distribution of Tcl. 
-
-# see <http://www.activestate.com/Products/ActiveTcl/>
-#     <http://www.tcl.tk/>
-
-If you want to use ActiveTcl binary package as the Tcl/Tk libraries, 
-please use the following configure options.
-
-   --with-tcl-dir=<ActiveTcl_root>
-   --with-tk-dir=<ActiveTcl_root>
-
-And use the followings if you need.
-
-   --with-tcllib=<libname>
-   --with-tklib=<libname>
-   --enable-tcltk-stubs
-
-For example, when you install ActiveTcl-8.4.x to '/usr/local/ActiveTcl', 
-
-   configure --with-tcl-dir=/usr/local/ActiveTcl/  \
-             --with-tk-dir=/usr/local/ActiveTcl/   \
-             --with-tcllib=tcl8.4                  \
-             --with-tklib=tk8.4                    \
-             --enable-tcltk-stubs
-
-It depends on your environment that you have to add the directory of 
-ActiveTcl's libraries to your library path when execute Ruby/Tk. 
-One of the way is to add entries to TCLLIBPATH environment variable, 
-and one of the others add to LD_LIBRARY_PATH environment variable
-
-Probably, using TCLLIBPATH is better. The value is appended at the 
-head of Tcl's 'auto_path' variable. You can see the value of the 
-variable by using 'Tk::AUTO_PATH.value' or 'Tk::AUTO_PATH.list'.
-
-For example, on Linux, one of the ways is to use LD_LIBRARY_PATH 
-environment variable. 
--------------------------------------------------------------------------
- [bash]$ LD_LIBRARY_PATH=/usr/local/ActiveTcl/lib:$LD_LIBRARY_PATH \
-         ruby your-Ruby/Tk-script
-
- [bash]$ LD_LIBRARY_PATH=/usr/local/ActiveTcl/lib:$LD_LIBRARY_PATH irb
--------------------------------------------------------------------------
-Based on it, the Tcl interpreter changes auto_path variable's value.
-
-Then, you'll be able to use Tcl/Tk extension libraries included in the
-ActiveTcl package (e.g. call TkPackage.require('BWidget'), and then,
-use functions/widgets of BWidget extention).

-Ruby/Tk does NOT support forking the process on which Tk interpreter
-is running (unless NEVER control Tk interpreter under the forked child 
-process). In the library 'tk.rb', a Tk interpreter is initialized. 
-Therefore, if you want running Tk under a child process, please call
-"require 'tk'" in the child process. 
-
-# If do fork and exec(<new Ruby/Tk>) on the child process, you can 
-# control Ruby/Tk interpreter on the child process by 'send' command 
-# of Tcl/Tk. About this, please see Tk.appsend and Tk.rb_appsend, or 
-# 'remote-tk.rb' and the sample 'sample/remote-ip_sample.rb'.

-For example, the following sample1 will NOT work, and sample2 will

-require 'tk'  ## init Tk interpreter under parent process

-# The format of the menu_spec is:
-#   [ menu_info, menu_info, ... ]
-#
-# And the format of the menu_info is:
-#   [
-#     [text, underline, configs], # menu button/entry (*1)
-#     [label, command, underline, accelerator, configs],    # command entry
-#     [label, TkVar_obj, underline, accelerator, configs],  # checkbutton entry
-#     [label, [TkVar_obj, value], 
-#                        underline, accelerator, configs],  # radiobutton entry
-#     [label, [[...menu_info...], [...menu_info...], ...], 
-#                        underline, accelerator, configs],  # cascade entry
-#     '---', # separator
-#     ...
-#   ]
-#
-# underline, accelerator, and configs are optional pearameters. 
-# Hashes are OK instead of Arrays. Then the entry type ('command', 
-# 'checkbutton', 'radiobutton' or 'cascade') is given by 'type' key
-# (e.g. :type=>'cascade'). When type is 'cascade', an array of menu_info
-# is acceptable for 'menu' key (then, create sub-menu).
-#
-# NOTE: (*1)
-#   If you want to make special menus (*.help for UNIX, *.system for Win, 
-#   and *.apple for Mac), append 'menu_name'=>name (name is 'help' for UNIX, 
-#   'system' for Win, and 'apple' for Mac) option to the configs hash of 
-#   menu button/entry information.

-  [ current support status of Tcl/Tk extensions ]
-
-The following list shows *CURRENT* status when this file was modifyed
-at last. If you want to add other Tcl/Tk extensions to the planed list
-(or change its status position), please request them at the ruby-talk,
-ruby-list, or ruby-dev ML. Although we cannot promise to support your 
-requests, we'll try to do. 
-
-If you want to check that wrapper libraries are ready to use on your 
-environment, please execute 'pkg_checker.rb' with no arguments. The 
-script may give you some hints about that.
-
-
-  ***** IMPORTANT NOTE **********************************************
-
-    'support' means that Ruby/Tk's wrapper libraries are released. 
-    'not support' does *NOT* mean that the extension doesn't work
-    on Ruby/Tk. 
-
-    Even if the status of the extension is 'not support', you can 
-    control the functions/widgets of the extension without wrapper 
-    libraries by Tk.tk_call(), Tk.ip_eval(), and so on. 
-
-    If you cannot use installed Tcl/Tk extension, please check the 
-    followings. 
-
-     (1) On your Tcl/Tk, does the extention work?
-
-     (2) Do DLL libraries of the extension exist on DLL load-path?
-         (See also "<ruby archive>/ext/tcltklib/README.ActiveTcl")
-
-     (3) Is the Tcl library directory of the extension included in 
-         library search-path of the Tcl interpreter linked Ruby/Tk?
-
-    The check results may request you to do some setup operations 
-    before using the extension. If so, then please write the step 
-    of setup oprations into the "setup.rb" file in the directory 
-    of the wrapper libraries for the extention (It is the wrapper
-    libraries have the standard structure of the libraries in this 
-    directory). The "setup" file is required before requiring the 
-    Tcl library package (TkPackage.require(<libname>)).

-#   * Part of tcllib extension
-#   * Provides for a scrollbar to automatically mapped and unmapped as needed
-#
-# (The following is the original description of the library.)
-#
-# This package allows scrollbars to be mapped and unmapped as needed 
-# depending on the size and content of the scrollbars scrolled widget. 
-# The scrollbar must be managed by either pack or grid, other geometry 
-# managers are not supported.
-#
-# When managed by pack, any geometry changes made in the scrollbars parent 
-# between the time a scrollbar is unmapped, and when it is mapped will be 
-# lost. It is an error to destroy any of the scrollbars siblings while the 
-# scrollbar is unmapped. When managed by grid, if anything becomes gridded 
-# in the same row and column the scrollbar occupied it will be replaced by 
-# the scrollbar when remapped.
-#
-# This package may be used on any scrollbar-like widget as long as it 
-# supports the set subcommand in the same style as scrollbar. If the set 
-# subcommand is not used then this package will have no effect.

-#
-#   * Part of tcllib extension
-#   * Simple plotting and charting package
-#
-# (The following is the original description of the library.)
-#
-# Plotchart is a Tcl-only package that focuses on the easy creation of 
-# xy-plots, barcharts and other common types of graphical presentations. 
-# The emphasis is on ease of use, rather than flexibility. The procedures 
-# that create a plot use the entire canvas window, making the layout of the 
-# plot completely automatic.
-#
-# This results in the creation of an xy-plot in, say, ten lines of code:
-# --------------------------------------------------------------------
-#    package require Plotchart
-#
-#    canvas .c -background white -width 400 -height 200
-#    pack   .c -fill both
-#
-#    #
-#    # Create the plot with its x- and y-axes
-#    #
-#    set s [::Plotchart::createXYPlot .c {0.0 100.0 10.0} {0.0 100.0 20.0}]
-#
-#    foreach {x y} {0.0 32.0 10.0 50.0 25.0 60.0 78.0 11.0 } {
-#        $s plot series1 $x $y
-#    }
-#
-#    $s title "Data series"
-# --------------------------------------------------------------------
-#
-# A drawback of the package might be that it does not do any data management. 
-# So if the canvas that holds the plot is to be resized, the whole plot must 
-# be redrawn. The advantage, though, is that it offers a number of plot and 
-# chart types:
-#
-#    * XY-plots like the one shown above with any number of data series.
-#    * Stripcharts, a kind of XY-plots where the horizontal axis is adjusted 
-#      automatically. The result is a kind of sliding window on the data 
-#      series.
-#    * Polar plots, where the coordinates are polar instead of cartesian.
-#    * Isometric plots, where the scale of the coordinates in the two 
-#      directions is always the same, i.e. a circle in world coordinates 
-#      appears as a circle on the screen.
-#      You can zoom in and out, as well as pan with these plots (Note: this 
-#      works best if no axes are drawn, the zooming and panning routines do 
-#      not distinguish the axes), using the mouse buttons with the control 
-#      key and the arrow keys with the control key.
-#    * Piecharts, with automatic scaling to indicate the proportions.
-#    * Barcharts, with either vertical or horizontal bars, stacked bars or 
-#      bars side by side.
-#    * Timecharts, where bars indicate a time period and milestones or other 
-#      important moments in time are represented by triangles.
-#    * 3D plots (both for displaying surfaces and 3D bars)

-#------------------------------------------------------------------------------
-# ==== Introduction. ====
-#
-# To create this version of the Ruby/Tk widget demo, I took the
-# ruby-tk81-demos and removed all the Kanji strings and comments.  I
-# have tried to restore the original English strings and comments
-# using the Tcl/Tk8.2.2 version of the widget demo. 
-#
-# When I tried running the Kanji version, all I got was a mostly blank
-# panel with a non-functional "File" button. I disovered that if all
-# non-ASCII characters were replaced with blanks, then I could get the
-# gutted stuff running.  
-#
-# Since English Ruby/Tk documentation is lacking and I needed this
-# code to see how it worked and to use as the basis of my try-it
-# prototype (The Ruby Yielding Interactive Toolkit), plus the fact
-# that no help was forthcoming for making the Kanji version work (plus
-# the fact that I can't read Kanji anyway), I decided to embark on
-# this English restoration project. 
-#
-# Thanks to everyone who worked on the original Ruby/Tk widget demo
-# (and the preceding Tcl/Tk version for that matter).  The
-# comparatively simple task of changing text strings and comments has
-# made me appreciate the great amount of original work that went into
-# this.
-#
-# -- Conrad Schneiker, 2000-07-23.
-#------------------------------------------------------------------------------
-
-#------------------------------------------------------------------------------
-# ==== Known bugs. ====
-#
-# ^C-ing the demo gives Ruby interrupt and stack message; clean exit needed.
-# Font settings don't work correctly.
-# Dismissing the embedded windows demo (tkwind.rb) kills the widget demo.
-# Rerunning the canvas item demo from the code widow get errors.
-# The "press me" button in the canvas item demo doesn't time out.
-# The simple 2 d plot starts up extremely slow compared to the Tcl version.
-# The first item message on the icon menu on the menu and cascades demo doesn't work.

-
-widget -	Contains a collection of demonstrations of the widgets
-		currently available in the Tk library.  Most of the .tcl
-		files are scripts for individual demos available through
-		the "widget" program.
-
-ixset -		A simple Tk-based wrapper for the "xset" program, which
-		allows you to interactively query and set various X options
-		such as mouse acceleration and bell volume.  Thanks to
-		Pierre David for contributing this example.
-
-rolodex -	A mock-up of a simple rolodex application.  It has much of
-		the user interface for such an application but no back-end
-		database.  This program was written in response to Tom
-		LaStrange's toolkit benchmark challenge.
-
-tcolor -	A color editor.  Allows you to edit colors in several
-		different ways, and will also perform automatic updates
-		using "send".
-
-rmt -		Allows you to "hook-up" remotely to any Tk application
-		on the display.  Select an application with the menu,
-		then just type commands:  they'll go to that application.
-
-timer -		Displays a seconds timer with start and stop buttons.
-		Control-c and control-q cause it to exit.
-
-browse -	A simple directory browser.  Invoke it with and argument
-		giving the name of the directory you'd like to browse.
-		Double-click on files or subdirectories to browse them.
-		Control-c and control-q cause the program to exit.

-This window is a text widget.  It displays one or more lines of text
-and allows you to edit the text.  Here is a summary of the things you
-can do to a text widget:
-
-1. Scrolling. Use the scrollbar to adjust the view in the text window.
-
-2. Scanning. Press mouse button 2 in the text window and drag up or down.
-This will drag the text at high speed to allow you to scan its contents.
-
-3. Insert text. Press mouse button 1 to set the insertion cursor, then
-type text.  What you type will be added to the widget.
-
-4. Select. Press mouse button 1 and drag to select a range of characters.
-Once you've released the button, you can adjust the selection by pressing
-button 1 with the shift key down.  This will reset the end of the
-selection nearest the mouse cursor and you can drag that end of the
-selection by dragging the mouse before releasing the mouse button.
-You can double-click to select whole words or triple-click to select
-whole lines.
-
-5. Delete and replace. To delete text, select the characters you'd like
-to delete and type Backspace or Delete.  Alternatively, you can type new
-text, in which case it will replace the selected text.
-
-6. Copy the selection. To copy the selection into this window, select
-what you want to copy (either here or in another application), then
-click button 2 to copy the selection to the point of the mouse cursor.
-
-7. Edit.  Text widgets support the standard Motif editing characters
-plus many Emacs editing characters.  Backspace and Control-h erase the
-character to the left of the insertion cursor.  Delete and Control-d
-erase the character to the right of the insertion cursor.  Meta-backspace
-deletes the word to the left of the insertion cursor, and Meta-d deletes
-the word to the right of the insertion cursor.  Control-k deletes from
-the insertion cursor to the end of the line, or it deletes the newline
-character if that is the only thing left on the line.  Control-o opens
-a new line by inserting a newline character to the right of the insertion
-cursor.  Control-t transposes the two characters on either side of the
-insertion cursor. #{
-      if undo_support
-	undo_text = "Control-z undoes the last editing action performed,\nand "
-	case $tk_platform['platform']
-	when "unix", "macintosh"
-	  undo_text << "Control-Shift-z"
-	else # 'windows'
-	  undo_text << "Control-y"
-	end
-	undo_text << "redoes undone edits."
-      else
-	""
-      end
-}
-
-7. Resize the window.  This widget has been configured with the "setGrid"
-option on, so that if you resize the window it will always resize to an
-even number of characters high and wide.  Also, if you make the window
-narrow you can see that long lines automatically wrap around onto
-additional lines so that all the information is always visible.

-This directory contains "widget" demo for the Japanized Tcl7.6/Tk4.2.
-Most of the messages in the original are translated to Japanese.
-But other tools in this directory are not translated.

-Following 2 kanji fonts are defined at the beginning of the file "widget."

-These fonts are all part of the core distribution of X11R5, so

-But if you don't have these fonts, replace them with appropriate ones.
-"-*--14-*-jisx0208.1983-0" will be a good choice.

-This directory contains a collection of programs to demonstrate
-the features of the Tk toolkit.  The programs are all scripts for
-"wish", a windowing shell.  If wish has been installed in /usr/local
-then you can invoke any of the programs in this directory just
-by typing its file name to your command shell.  Otherwise invoke
-wish with the file as its first argument, e.g., "wish hello".
-The rest of this file contains a brief description of each program.
-Files with names ending in ".tcl" are procedure packages used by one
-or more of the demo programs;  they can't be used as programs by
-themselves so they aren't described below.
-
-hello -		Creates a single button;  if you click on it, a message
-		is typed and the application terminates.
-
-widget -	Contains a collection of demonstrations of the widgets
-		currently available in the Tk library.  Most of the .tcl
-		files are scripts for individual demos available through
-		the "widget" program.
-
-ixset -		A simple Tk-based wrapper for the "xset" program, which
-		allows you to interactively query and set various X options
-		such as mouse acceleration and bell volume.  Thanks to
-		Pierre David for contributing this example.
-
-rolodex -	A mock-up of a simple rolodex application.  It has much of
-		the user interface for such an application but no back-end
-		database.  This program was written in response to Tom
-		LaStrange's toolkit benchmark challenge.
-
-tcolor -	A color editor.  Allows you to edit colors in several
-		different ways, and will also perform automatic updates
-		using "send".
-
-rmt -		Allows you to "hook-up" remotely to any Tk application
-		on the display.  Select an application with the menu,
-		then just type commands:  they'll go to that application.
-
-timer -		Displays a seconds timer with start and stop buttons.
-		Control-c and control-q cause it to exit.
-
-browse -	A simple directory browser.  Invoke it with and argument
-		giving the name of the directory you'd like to browse.
-		Double-click on files or subdirectories to browse them.
-		Control-c and control-q cause the program to exit.

-<p><p><b>Use the <tt>Tcl</tt>*<tt>InsertProc()</tt> functions</b></p>
-<ul><li>Three routines that overload basic file I/O operations:
-  <ul>
-  <li> <tt>TclStatInsertProc()</tt> </li>
-  <li> <tt>TclAccessInsertProc()</tt> </li>
-  <li> <tt>TclOpenFileChannelInsertProc()</tt> </li>
-  </ul></li></ul><ul><li>Allows us to implement a virtual filesystem that overlays the
-  real filesystem.</li></ul><ul><li>The virtual filesystem contains all the initialization scripts
-  as compiled-in strings.  The initialization scripts look like
-  they are resident on disk even though they are built in.</li></ul><ul><li>These functions first appeared in Tcl8.0.3.  
-  Presumably to support TclPro Wrapper.</li></ul><ul><li>The only documentation is comments on the code. 
-  See the Tcl source file <tt>generic/tclIOUtil.c</tt></li></ul></p>

-<h2 align="center">The <tt>TclStatInsertProc()</tt> Function</h2>
-<p><ul><li>Sole argument is a pointer to a function whose interface is the
-  same as <tt>stat()</tt></li></ul><ul><li>Functions are stacked. Tcl tries each <tt>stat</tt> function on the
-  list, beginning with the most recently inserted, until one succeeds.</li></ul></p>

-before you start to think it's a government hoax. <A HREF="http://server51.freshmeat.net/">Server 51</A> is our new hosting service for Open Source projects, based on Super Cool Space Alien Technology(TM). We hadn't planned to announce it quite so soon, and it's still in the alpha stage as we work day and night at integrating SCSAT with our terrestrial systems, but feel free to take a look around and see what's going on. When we're out of the testing stage and ready to make room for your project, we'll send word via your implants. Be listening.

-<DIV ALIGN="justify"><P>RabbIt is the mutating, caching webproxy which is used to speed up surfing over slow links like modems. It does this by removing advertising and background images and scaling down images to low quality JPEGs. RabbIT is written in Java and should be able to run on any platform. It does depend upon an image converter if imagescaleing is on. The recommended image converter is "convert" from the ImageMagick package.</DIV>
-<P><B>Changes:</B> Fixes have been made for a few bugs concerning keep alive and the HTTP response header, a bug with NT and cache directories, a bug concerning requests without a response body, a bug in GZIPHandler that caused it to not gzip already compressed (gzip or compress) streams, a bug in HTTPHeader regarding response phrases that are multiline, and a few bugs in ImageHandler and NCache. GZIPHandler has been built as an intermediate(*) to FilterHandler (this means that it is possible to gzip text/plain, etc., without filtering those streams) uuencoding has been added to the Coder, RabbIT now uses HTTP/1.1, HTMLParser now compiles cleanly with Jikes, and GeneralHeader has been created to allow for HTTPFooter (which is useful when sending chunked data).

-
-canvSticker.tcl
-	Heribert Dahms original "demo.tcl"
-	<p> creates DEMO.ps
-
-canvSticker2.tcl
-	compares "sticker" and "text"; press <1>, <2> or <1> ...
-	<p> creates DEMO.ps
-
-dial.tcl
-	demo of variations of the dial widget.
-
-load.tcl
-	Just a utility file, not a real demo.

-
-pie.tcl
-	The magic 3D spinning pie chart!
-
-vu.tcl
-	demo fo Vu widgets
-
-canvLabel.tcl
-	'label' is a canvas item just like 'text', but with -angle

-    This constant is used to get value of argument 
-    when the argument is passed by reference.
-
-=== Class Method
-: connect(oleserver)
-   returns running OLE automation object or WIN32OLE object from moniker.
-
-: const_load(ole [,obj])
-   defines the constants of OLE automation
-   server as 'obj' class constants. If 'obj' omitted, the default
-   is WIN32OLE.
-
-: new(oleserver)
-   returns OLE Automation object.
-
-: ole_free(obj)
-   invokes Release method of Dispatch interface of WIN32OLE object.
-   This method should not be used because this method exists for debugging WIN32OLE.
-
-: ole_reference_count(obj)
-   returns reference counter of Dispatch interface.
-   This method should not be used because this method exists for debugging WIN32OLE.
-
-: ole_show_help(info [,helpcontext])
-   displays helpfile.
-   The first argument specifies WIN32OLE_TYPE object or WIN32OLE_METHOD object 
-   or helpfile.
-
-=== Method
-: self[property]
-   gets property of OLE object.
-
-: self[property]=
-   sets property of OLE object.
-
-: _invoke(dispid, args, types)
-   runs the early binding method.
-   The dispid specifies Dispatch ID, args specifies the array of arguments,
-   types specifies array of the type of arguments.
-
-: each {...}
-   Iterates over each item of OLE collection which has IEnumVARIANT
-   interface.
-
-: invoke(method, args,...)
-   runs OLE method.
-
-: ole_func_methods
-   returns array of WIN32OLE_METHOD object which corresponds with function.
-
-: ole_get_methods
-   returns array of WIN32OLE_METHOD object which corresponds with get properties.
-
-: ole_method(method)
-   returns WIN32OLE_METHOD object which coreesponds with method 
-   which specified by argument.
-
-: ole_method_help(method)
-   alias of ole_method.
-
-: ole_methods
-   returns WIN32OLE_METHOD object which coreesponds with method.
-
-: ole_obj_help
-   returns WIN32OLE_TYPE object.
-
-: ole_put_methods
-   returns array of WIN32OLE_METHOD object which corresponds with put properties.
-
-: setproperty(property, key, val)
-   set property of OLE object. 
-   This method is used when the property has argument.
-
-   For example, in VB
-     obj.item("key") = val
-   in Win32OLE
-     obj.setproperty("item", "key", val)
-
-
-== WIN32OLE_EVENT class
-
-=== Class Method
-
-: new(ole, interface)
-   The new class method creates OLE event sink object to connect ole.
-   The ole must be WIN32OLE object, and interface is the interface
-   name of event.
-
-: message_loop
-    The message_loop class method translates and dispatches Windows 
-    message.
-
-=== Method
-: on_event([event]){...}
-    defines the callback of event.
-    If event omitted, defines the callback of all events.
-
-: on_event_with_outargs([event]) {...}
-    defines the callback of event.
-    If you want modify argument in callback, 
-
-== WIN32OLE_METHOD

---- Zlib::BEST_COMPRESSION
---- Zlib::DEFAULT_COMPRESSION
-
-    The integers representing compression levels which are
-    an argument for ((<Zlib::Deflate.new>)),
-    ((<Zlib::Deflate#deflate>)), and so on.
-
---- Zlib::FILTERED
---- Zlib::HUFFMAN_ONLY
---- Zlib::DEFAULT_STRATEGY
-
-    The integers representing compression methods which are
-    an argument for ((<Zlib::Deflate.new>)) and
-    ((<Zlib::Deflate#params>)).
-
---- Zlib::DEF_MEM_LEVEL
---- Zlib::MAX_MEM_LEVEL
-
-    The integers representing memory levels which are an
-    argument for ((<Zlib::Deflate.new>)),
-    ((<Zlib::Deflate#params>)), and so on.
-
---- Zlib::MAX_WBITS
-
-    The default value of ((|windowBits|)) which is an argument for
-    ((<Zlib::Deflate.new>)) and ((<Zlib::Inflate.new>)).
-
---- Zlib::NO_FLUSH

-    The return values of ((<Zlib::GzipFile#os_code>)) method.
-
-
-== Zlib::Error
-
-The superclass for all exceptions raised by Ruby/zlib.
-
-The following exceptions are defined as subclasses of Zlib::Error.
-These exceptions are raised when zlib library functions return
-with an error status.
-
-  * Zlib::StreamEnd
-  * Zlib::NeedDict
-  * Zlib::DataError
-  * Zlib::StreamError
-  * Zlib::MemError
-  * Zlib::BufError
-  * Zlib::VersionError
-
-=== SuperClass:
-
-* StandardError
-
-
-== Zlib::ZStream
-
-The abstract class for the stream which handles the compressed
-data. The operations are defined in the subclasses,
-((<Zlib::Deflate>)) for compression, and ((<Zlib::Inflate>))
-for decompression.
-
-An instance of Zlib::ZStream has one stream (struct zstream) and
-two variable-length buffers which associated to the input
-(next_in) of the stream and the output (next_out) of the stream.
-In this document, "input buffer" means the buffer for input, and
-"output buffer" means the buffer for output.
-
-Data inputed into an instance of Zlib::ZStream are temporally
-stored into the end of input buffer, and then data in input buffer
-are processed from the beginning of the buffer until no more
-output from the stream is produced (i.e. until avail_out > 0
-after processing). During processing, output buffer is allocated
-and expanded automatically to hold all output data.
-
-Some particular instance methods consume the data in output buffer
-and return them as a String.
-
-Here is an ascii art for describing above:
-
-     +================ an instance of Zlib::ZStream ================+
-     ||                                                            ||

-         v                                                      |
-     "output data"                                         "input data"
-
-If an error is occurred during processing input buffer,
-an exception which is a subclass of ((<Zlib::Error>)) is raised.
-At that time, both input and output buffer keeps their conditions
-at the time when the error is occurred.

-
-=== Class Methods:
-
---- Zlib::ZStream.new
-
-    See ((<Zlib::Deflate.new>)) and ((<Zlib::Inflate.new>)).
-
-=== Methods:
-
---- Zlib::ZStream#avail_in
-
-    Returns bytes of data in input buffer.
-    Normally, returns 0.
-
---- Zlib::ZStream#avail_out
-
-    Returns bytes of free spaces in output buffer.
-    Because the free spaces are allocated automatically,
-    this method returns 0 normally.
-
---- Zlib::ZStream#avail_out = size
-
-    Allocates free spaces of ((|size|)) bytes in output buffer.
-    If there are more than ((|size|)) bytes spaces in the buffer,
-    the buffer is truncated.
-    Because the free spaces are allocated automatically,
-    you usually need not to use this method.
-
---- Zlib::ZStream#flush_next_in
-
-    Flushes input buffer and returns all data in that buffer.
-
---- Zlib::ZStream#flush_next_out
-
-    Flushes output buffer and returns all data in that buffer.
-
---- Zlib::ZStream#total_in
-
-    Returns the total bytes of the input data to the stream.
-
---- Zlib::ZStream#total_out
-
-    Returns the total bytes of the output data from the stream.
-
---- Zlib::ZStream#data_type
-
-    Guesses the type of the data which have been inputed into
-    the stream. The returned value is either ((<Zlib::BINARY>)),
-    ((<Zlib::ASCII>)), or ((<Zlib::UNKNOWN>)).
-
---- Zlib::ZStream#adler
-
-    Returns the alder-32 checksum.
-
---- Zlib::ZStream#reset
-
-    Resets and initializes the stream. All data in both
-    input and output buffer are discarded.
-
---- Zlib::ZStream#finish
-
-    Finishes the stream and flushes output buffer.
-    See ((<Zlib::Deflate#finish>)) and ((<Zlib::Inflate#finish>))
-    for detail of the behavior.
-
---- Zlib::ZStream#finished?
---- Zlib::ZStream#stream_end?
-
-    Returns true if the stream is finished.
-
---- Zlib::ZStream#close
---- Zlib::ZStream#end
-
-    Closes the stream. All operations on the closed stream
-    will raise an exception.
-
---- Zlib::ZStream#closed?
---- Zlib::ZStream#ended?
-
-    Returns true if the stream closed.
-
-
-== Zlib::Deflate
-
-The class for compressing string data.
-
-=== SuperClass:
-
-* ((<Zlib::ZStream>))
-
-=== Class Methods:
-
---- Zlib::Deflate.deflate(string[, level])
-
-    Compresses ((|string|)). The avail values of ((|level|)) are
-    ((<Zlib::NO_COMPRESSION>)), ((<Zlib::BEST_SPEED>)),
-    ((<Zlib::BEST_COMPRESSION>)), ((<Zlib::DEFAULT_COMPRESSION>)),
-    and the integer from 0 to 9.
-
-    This method is almost equivalent to the following code:
-
-      def deflate(string, level)
-        z = Zlib::Deflate.new(level)
-        dst = z.deflate(string, Zlib::FINISH)
-        z.close
-        dst
-      end
-
---- Zlib::Deflate.new([level[, windowBits[, memlevel[, strategy]]]])
-
-    Creates a new deflate stream for compression.
-    See zlib.h for details of each argument.
-    If an argument is nil, the default value of that
-    argument is used.
-
-=== Methods:
-
---- Zlib::Deflate#clone
-
-    Duplicates the deflate stream.
-
---- Zlib::Deflate#deflate(string[, flush])
-
-    Inputs ((|string|)) into the deflate stream and returns
-    the output from the stream. Calling this method,
-    both input and output buffer of the stream are flushed.
-    If ((|string|)) is nil, this method finishes the stream,
-    just like ((<Zlib::ZStream#finish>)).
-    The value of ((|flush|)) should be either ((<Zlib::NO_FLUSH>)),
-    ((<Zlib::SYNC_FLUSH>)), ((<Zlib::FULL_FLUSH>)), or
-    ((<Zlib::FINISH>)).
-    See zlib.h for details.
-
---- Zlib::Deflate#<< string
-
-    Inputs ((|string|)) into the deflate stream just like
-    ((<Zlib::Deflate#deflate>)), but returns Zlib::Deflate object
-    itself. The output from the stream is preserved in output
-    buffer.
-
---- Zlib::Deflate#flush([flush])
-
-    This method is equivalent to (({deflate('', ((|flush|)))})).
-    If ((|flush|)) is omitted, ((<Zlib::SYNC_FLUSH>)) is used
-    as ((|flush|)). This method is just provided for
-    readability of your Ruby script.
-
---- Zlib::Deflate#finish
-
-    Finishes the stream. This method is equivalent to
-    (({deflate('', Zlib::FINISH)})).
-
---- Zlib::Deflate#params(level, strategy)
-
-    Changes the parameters of the deflate stream.
-    See zlib.h for details. The output from the stream
-    by changing the params is preserved in output buffer.
-
---- Zlib::Deflate#set_dictionary(string)
-
-    Sets the preset dictionary and returns ((|string|)).
-    This method is available just only after
-    ((<Zlib::Deflate.new>)) or ((<Zlib::ZStream#reset>)) method
-    was called. See zlib.h for details.
-
-
-== Zlib::Inflate
-
-The class for decompressing compressed data.
-Unlike ((<Zlib::Deflate>)), an instance of this class is not able
-to duplicate (clone, dup) itself.
-
-=== SuperClass:
-
-* ((<Zlib::ZStream>))
-
-=== Class Methods:
-
---- Zlib::Inflate.inflate(string)
-
-    Decompresses ((|string|)). Raises a ((<Zlib::NeedDict>))
-    exception if a preset dictionary is needed for decompression.
-
-    This method is almost equivalent to the following code:
-
-      def inflate(string)
-        zstream = Zlib::Inflate.new
-        buf = zstream.inflate(string)
-        zstream.finish
-        zstream.close
-        buf
-      end
-
---- Zlib::Inflate.new([windowBits])
-
-    Creates a new inflate stream for decompression.
-    See zlib.h for details of the argument.
-    If ((|windowBits|)) is nil, the default value is used.
-
-=== Methods:
-
---- Zlib::Inflate#inflate(string)
-
-    Inputs ((|string|)) into the inflate stream and returns
-    the output from the stream. Calling this method,
-    both input and output buffer of the stream are flushed.
-    If ((|string|)) is nil, this method finishes the stream,
-    just like ((<Zlib::ZStream#finish>)).
-
-    Raises a ((<Zlib::NeedDict>)) exception if a preset
-    dictionary is needed to decompress. Set the dictionary
-    by ((<Zlib::Inflate#set_dictionary>)) and then call
-    this method again with an empty string.
-
---- Zlib::Inflate#<< string
-
-    Inputs ((|string|)) into the inflate stream just like
-    ((<Zlib::Inflate#inflate>)), but returns Zlib::Inflate object
-    itself. The output from the stream is preserved in output
-    buffer.
-
---- Zlib::Inflate#finish
-
-    Finishes the inflate stream and returns the garbage
-    following the compressed data. Raises an exception
-    if the stream is not finished
-    (i.e. ((<Zlib::ZStream#finished?>)) doesn't returns true).
-
-    The inflate stream finishes itself as soon as it meets
-    the end code of the compressed data, you need not to call
-    this method explicitly. However, this method is useful
-    for checking whether the data is correctly ended or not.
-
---- Zlib::Inflate#set_dictionary(string)
-
-    Sets the preset dictionary and returns ((|string|))
-    This method is available just only after a ((<Zlib::NeedDict>))
-    exception was raised. See zlib.h for details.
-
---- Zlib::Inflate#sync(string)
-
-    Inputs ((|string|)) into the end of input buffer and
-    skips data until a full flush point can be found.
-    If the point is found in the buffer, this method flushes
-    the buffer and returns false. Otherwise it returns true
-    and the following data of full flush point is preserved
-    in the buffer.
-
---- Zlib::Inflate#sync_point?
-
-    What is this?
-
-
-== Zlib::GzipFile
-
-The abstract class for handling a gzip formatted compressed file.
-The operations are defined in the subclasses,
-((<Zlib::GzipReader>)) for reading, and ((<Zlib::GzipWriter>))
-for writing.
-
-GzipReader should be used with associating an instance of IO class
-(or an object which has the same methods as IO has).

-    See ((<Zlib::GzipReader.wrap>)) and ((<Zlib::GzipWriter.wrap>)).
-
---- Zlib::GzipFile.open(args...) {|gz| ... }
-
-    See ((<Zlib::GzipReader.open>)) and ((<Zlib::GzipWriter.open>)).
-

---- Zlib::GzipFile#to_io
-
-    Same as IO.
-

-    of the associated IO object. Returns the associated IO object.
-
---- Zlib::GzipFile#finish
-

-
-
-== Zlib::GzipReader
-
-The class for reading a gzipped file. GzipReader should be used
-with associating an instance of IO class (or an object which has
-the same methods as IO has).
-
-    Zlib::GzipReader.open('hoge.gz') {|gz|
-      print gz.read
-    }
-
-    f = File.open('hoge.gz')
-    gz = Zlib::GzipReader.new(f)

-
-=== SuperClass:
-
-* ((<Zlib::GzipFile>))
-
-=== Included Modules:
-
-* Enumerable
-
-=== Class Methods:
-
---- Zlib::GzipReader.new(io)
-
-    Creates a GzipReader object associated with ((|io|)).
-    The GzipReader object reads gzipped data from ((|io|)),
-    and parses/decompresses them. At least, ((|io|)) must have
-    read method that behaves same as read method in IO class.
-
-    If the gzip file header is incorrect, raises an
-    ((<Zlib::GzipFile::Error>)) exception.
-
---- Zlib::GzipReader.wrap(io) {|gz| ... }
-
-    Creates a GzipReader object associated with ((|io|)), and
-    executes the block with the newly created GzipReader object,
-    just like File::open. The GzipReader object will be closed
-    automatically after executing the block. If you want to keep
-    the associated IO object opening, you may call
-    ((<Zlib::GzipFile#finish>)) method in the block.
-
---- Zlib::GzipReader.open(filename)
---- Zlib::GzipReader.open(filename) {|gz| ... }
-
-    Opens a file specified by ((|filename|)) as a gzipped file,
-    and returns a GzipReader object associated with that file.
-    Further details of this method are same as
-    ((<Zlib::GzipReader.new>)) and ((<ZLib::GzipReader.wrap>)).
-
-=== �᥽�å�:
-
---- Zlib::GzipReader#eof
---- Zlib::GzipReader#eof?
-
-    Returns true if the object reaches the end of compressed data.
-    Note that eof? does ((*not*)) return true when reaches the
-    end of ((*file*)).
-
---- Zlib::GzipReader#pos
---- Zlib::GzipReader#tell
-
-    Returns the total bytes of data decompressed until now.
-    Not that it does ((*not*)) the position of file pointer.
-
---- Zlib::GzipReader#each([rs])
---- Zlib::GzipReader#each_line([rs])
---- Zlib::GzipReader#each_byte([rs])
---- Zlib::GzipReader#gets([rs])

---- Zlib::GzipReader#readline([rs])
---- Zlib::GzipReader#readlines([rs])
---- Zlib::GzipReader#ungetc(char)
-
-    Same as IO, but raises ((<Zlib::Error>)) or
-    ((<Zlib::GzipFile::Error>)) exception if an error was found
-    in the gzip file.
-
-    Be careful of the footer of gzip file. A gzip file has
-    the checksum of pre-compressed data in its footer.
-    GzipReader checks all uncompressed data against that checksum
-    at the following cases, and if failed, raises
-    ((<Zlib::GzipFile::NoFooter>)), ((<Zlib::GzipFile::CRCError>)),
-    or ((<Zlib::GzipFile::LengthError>)) exception.
-
-    * When an reading request is received beyond the end of file
-      (the end of compressed data).
-      That is, when ((<Zlib::GzipReader#read>)),
-      ((<Zlib::GzipReader#gets>)), or some other methods for reading
-      returns nil.
-
-    * When ((<Zlib::GzipFile#close>)) method is called after
-      the object reaches the end of file.
-
-    * When ((<Zlib::GzipReader#unused>)) method is called after
-      the object reaches the end of file.
-
---- Zlib::GzipReader#rewind
-
-    Resets the position of the file pointer to the point
-    created the GzipReader object.
-    The associated IO object need to respond to seek method.
-
---- Zlib::GzipReader#unused
-
-    Returns the rest of the data which had read for parsing gzip
-    format, or nil if the whole gzip file is not parsed yet.
-
-
-== Zlib::GzipWriter
-
-The class for writing a gzipped file. GzipWriter should be used
-with associate with an instance of IO class (or an object which
-has the same methods as IO has).
-
-    Zlib::GzipWriter.open('hoge.gz') {|gz|
-      gz.write 'jugemu jugemu gokou no surikire...'
-    }
-
-    f = File.open('hoge.gz', 'w')
-    gz = Zlib::GzipWriter.new(f)
-    gz.write 'jugemu jugemu gokou no surikire...'
-    gz.close
-
-NOTE: Due to the limitation in finalizer of Ruby, you must close
-explicitly GzipWriter object by ((<Zlib::GzipWriter#close>)) etc.
-Otherwise, GzipWriter should be not able to write gzip footer and
-generate broken gzip file.
-
-=== SuperClass:
-
-* ((<Zlib::GzipFile>))
-
-=== Class Methods:
-
---- Zlib::GzipWriter.new(io[, level[, strategy]])
-
-    Creates a GzipWriter object associated with ((|io|)).
-    ((|level|)) and ((|strategy|)) should be same as the
-    arguments of ((<Zlib::Deflate.new>)). The GzipWriter object
-    writes gzipped data to ((|io|)). At least, ((|io|)) must

-    in IO class.
-
---- Zlib::GzipWriter.wrap(io[, level[, strategy]]) {|gz| ... }
-
-    Creates a GzipWriter object associated with ((|io|)), and
-    executes the block with the newly created GzipWriter object,
-    just like File::open. The GzipWriter object will be closed

-    associated with that file. Further details of this method
-    are same as ((<Zlib::GzipWriter.new>)) and
-    ((<Zlib::GzipWriter#wrap>)).
-
-
-=== Methods:
-
---- Zlib::GzipWriter#close
---- Zlib::GzipWriter#finish
-
-    Closes the GzipFile object. This method calls close method
-    of the associated IO object. Returns the associated IO object.
-    See ((<Zlib::GzipFile#close>)) and ((<Zlib::GzipFile#finish>))
-    for the difference between close and finish.
-
-    ((*NOTE: Due to the limitation in finalizer of Ruby, you must
-    close GzipWriter object explicitly. Otherwise, GzipWriter
-    should be not able to write gzip footer and generate broken
-    gzip file.*))
-
---- Zlib::GzipWriter#pos
---- Zlib::GzipWriter#tell
-
-    Returns the total bytes of data compressed until now.

---- Zlib::GzipWriter#write(str)
-
-    Same as IO.
-
---- Zlib::GzipWriter#flush([flush])
-
-    Flushes all the internal buffers of the GzipWriter object.
-    The meaning of ((|flush|)) is same as one of the argument of
-    ((<Zlib::Deflate#deflate>)).
-    ((<Zlib::SYNC_FLUSH>)) is used if ((|flush|)) is omitted.
-    It is no use giving ((|flush|)) ((<Zlib::NO_FLUSH>)).
-
---- Zlib::GzipWriter#mtime= time
-
-    Sets last modification time to be stored in the gzip file
-    header. ((<Zlib::GzipFile::Error>)) exception will be raised
-    if this method is called after writing method (like
-    ((<Zlib::GzipWriter#write>))) was called.
-
---- Zlib::GzipWriter#orig_name= filename
-
-    Sets original filename to be stored in the gzip file header.
-    ((<Zlib::GzipFile::Error>)) exception will be raised
-    if this method is called after writing method (like
-    ((<Zlib::GzipWriter#write>))) was called.
-
---- Zlib::GzipWriter#comment= string
-
-    Sets comments to be stored in the gzip file header.
-    ((<Zlib::GzipFile::Error>)) exception will be raised

-* ((<Zlib::GzipReader#unused>)) returns nil after closing.
-
-* Now you are up to call ((<Zlib::GzipWriter#close>)) explicitly
-to avoid segv in finalizer.
-((<[ruby-dev:11915]|URL:http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-dev/11915>))
-
-* divided initialize from new.
-
-* remove sanity checks for arguments for deflateInit2 and
-  inflateInit2.
-
-* adapted the behavior of ((<Zlib::GzipWriter#puts>)) to Ruby-1.7.
-
-* Made all functions static.

- * Document-class: Zlib::ZStream
- *
- * Zlib::ZStream is the abstract class for the stream which handles the
- * compressed data. The operations are defined in the subclasses:
- * Zlib::Deflate for compression, and Zlib::Inflate for decompression.
- *
- * An instance of Zlib::ZStream has one stream (struct zstream in the source)
- * and two variable-length buffers which associated to the input (next_in) of
- * the stream and the output (next_out) of the stream. In this document,
- * "input buffer" means the buffer for input, and "output buffer" means the
- * buffer for output.
- *
- * Data input into an instance of Zlib::ZStream are temporally stored into
- * the end of input buffer, and then data in input buffer are processed from
- * the beginning of the buffer until no more output from the stream is
- * produced (i.e. until avail_out > 0 after processing).  During processing,
- * output buffer is allocated and expanded automatically to hold all output
- * data.
- *
- * Some particular instance methods consume the data in output buffer and
- * return them as a String.
- *
- * Here is an ascii art for describing above:
- *
- *    +================ an instance of Zlib::ZStream ================+
- *    ||                                                            ||
- *    ||     +--------+          +-------+          +--------+      ||
- *    ||  +--| output |<---------|zstream|<---------| input  |<--+  ||
- *    ||  |  | buffer |  next_out+-------+next_in   | buffer |   |  ||
- *    ||  |  +--------+                             +--------+   |  ||
- *    ||  |                                                      |  ||
- *    +===|======================================================|===+
- *        |                                                      |
- *        v                                                      |
- *    "output data"                                         "input data"
- *
- * If an error occurs during processing input buffer, an exception which is a
- * subclass of Zlib::Error is raised.  At that time, both input and output
- * buffer keep their conditions at the time when the error occurs.
- *
- * == Method Catalogue
- *
- * Many of the methods in this class are fairly low-level and unlikely to be
- * of interest to users.  In fact, users are unlikely to use this class
- * directly; rather they will be interested in Zlib::Inflate and
- * Zlib::Deflate.
- *
- * The higher level methods are listed below.
- *
- * - #total_in
- * - #total_out
- * - #data_type
- * - #adler
- * - #reset
- * - #finish
- * - #finished?

- * Document-class: Zlib::GzipReader
- *
- * Zlib::GzipReader is the class for reading a gzipped file.  GzipReader should
- * be used an IO, or -IO-lie, object.
- *
- *   Zlib::GzipReader.open('hoge.gz') {|gz|
- *     print gz.read
- *   }
- *
- *   File.open('hoge.gz') do |f|
- *     gz = Zlib::GzipReader.new(f)
- *     print gz.read
- *     gz.close
- *   end
- *
- *   # TODO: test these.  Are they equivalent?  Can GzipReader.new take a
- *   # block?
- *
- * == Method Catalogue
- *
- * The following methods in Zlib::GzipReader are just like their counterparts
- * in IO, but they raise Zlib::Error or Zlib::GzipFile::Error exception if an
- * error was found in the gzip file.
- * - #each
- * - #each_line
- * - #each_byte
- * - #gets
- * - #getc
- * - #lineno
- * - #lineno=
- * - #read
- * - #readchar
- * - #readline
- * - #readlines
- * - #ungetc
- *
- * Be careful of the footer of the gzip file. A gzip file has the checksum of
- * pre-compressed data in its footer. GzipReader checks all uncompressed data
- * against that checksum at the following cases, and if it fails, raises
- * <tt>Zlib::GzipFile::NoFooter</tt>, <tt>Zlib::GzipFile::CRCError</tt>, or
- * <tt>Zlib::GzipFile::LengthError</tt> exception.
- *
- * - When an reading request is received beyond the end of file (the end of
- *   compressed data). That is, when Zlib::GzipReader#read,
- *   Zlib::GzipReader#gets, or some other methods for reading returns nil.
- * - When Zlib::GzipFile#close method is called after the object reaches the
- *   end of file.
- * - When Zlib::GzipReader#unused method is called after the object reaches
- *   the end of file.
- *
- * The rest of the methods are adequately described in their own
- * documentation.

- * Zlib::GzipWriter
- *
- * There are two important base classes for the classes above: Zlib::ZStream
- * and Zlib::GzipFile.  Everything else is an error class.
- *
- * == Constants
- *
- * Here's a list.
- *
- *   Zlib::VERSION
- *       The Ruby/zlib version string.
- *
- *   Zlib::ZLIB_VERSION
- *       The string which represents the version of zlib.h.
- *
- *   Zlib::BINARY
- *   Zlib::ASCII
- *   Zlib::UNKNOWN
- *       The integers representing data types which Zlib::ZStream#data_type
- *       method returns.
- *
- *   Zlib::NO_COMPRESSION
- *   Zlib::BEST_SPEED
- *   Zlib::BEST_COMPRESSION
- *   Zlib::DEFAULT_COMPRESSION
- *       The integers representing compression levels which are an argument
- *       for Zlib::Deflate.new, Zlib::Deflate#deflate, and so on.
- *
- *   Zlib::FILTERED
- *   Zlib::HUFFMAN_ONLY
- *   Zlib::DEFAULT_STRATEGY
- *       The integers representing compression methods which are an argument
- *       for Zlib::Deflate.new and Zlib::Deflate#params.
- *
- *   Zlib::DEF_MEM_LEVEL
- *   Zlib::MAX_MEM_LEVEL
- *       The integers representing memory levels which are an argument for
- *       Zlib::Deflate.new, Zlib::Deflate#params, and so on.
- *
- *   Zlib::MAX_WBITS
- *       The default value of windowBits which is an argument for
- *       Zlib::Deflate.new and Zlib::Inflate.new.
- *
- *   Zlib::NO_FLUSH
- *   Zlib::SYNC_FLUSH
- *   Zlib::FULL_FLUSH
- *   Zlib::FINISH
- *       The integers to control the output of the deflate stream, which are
- *       an argument for Zlib::Deflate#deflate and so on.
- *
- *   Zlib::OS_CODE
- *   Zlib::OS_MSDOS
- *   Zlib::OS_AMIGA

-/*
- *  A <code>File</code> is an abstraction of any file object accessible
- *  by the program and is closely associated with class <code>IO</code>
- *  <code>File</code> includes the methods of module
- *  <code>FileTest</code> as class methods, allowing you to write (for
- *  example) <code>File.exist?("foo")</code>.
- *     
- *  In the description of File methods,
- *  <em>permission bits</em> are a platform-specific
- *  set of bits that indicate permissions of a file. On Unix-based
- *  systems, permissions are viewed as a set of three octets, for the
- *  owner, the group, and the rest of the world. For each of these
- *  entities, permissions may be set to read, write, or execute the
- *  file:
- *     
- *  The permission bits <code>0644</code> (in octal) would thus be
- *  interpreted as read/write for owner, and read-only for group and
- *  other. Higher-order bits may also be used to indicate the type of
- *  file (plain, directory, pipe, socket, and so on) and various other
- *  special features. If the permissions are for a directory, the
- *  meaning of the execute bit changes; when set the directory can be
- *  searched.
- *     
- *  On non-Posix operating systems, there may be only the ability to
- *  make a file read-only or read-write. In this case, the remaining
- *  permission bits will be synthesized to resemble typical values. For
- *  instance, on Windows NT the default permission bits are
- *  <code>0644</code>, which means read/write for owner, read-only for
- *  all others. The only change that can be made is to make the file
- *  read-only, which is reported as <code>0444</code>.

- *  Class <code>IO</code> is the basis for all input and output in Ruby.
- *  An I/O stream may be <em>duplexed</em> (that is, bidirectional), and
- *  so may use more than one native operating system stream.
- *     
- *  Many of the examples in this section use class <code>File</code>,
- *  the only standard subclass of <code>IO</code>. The two classes are
- *  closely associated.
- *     
- *  As used in this section, <em>portname</em> may take any of the
- *  following forms.
- *     
- *  * A plain string represents a filename suitable for the underlying
- *    operating system.
- *     
- *  * A string starting with ``<code>|</code>'' indicates a subprocess.
- *    The remainder of the string following the ``<code>|</code>'' is
- *    invoked as a process with appropriate input/output channels
- *    connected to it.
- *     
- *  * A string equal to ``<code>|-</code>'' will create another Ruby
- *    instance as a subprocess.
- *     
- *  Ruby will convert pathnames between different operating system
- *  conventions if possible. For instance, on a Windows system the
- *  filename ``<code>/gumby/ruby/test.rb</code>'' will be opened as
- *  ``<code>\gumby\ruby\test.rb</code>''. When specifying a
- *  Windows-style filename in a Ruby string, remember to escape the
- *  backslashes:
- *     
- *     "c:\\gumby\\ruby\\test.rb"
- *     
- *  Our examples here will use the Unix-style forward slashes;
- *  <code>File::SEPARATOR</code> can be used to get the
- *  platform-specific separator character.
- *     
- *  I/O ports may be opened in any one of several different modes, which
- *  are shown in this section as <em>mode</em>. The mode may
- *  either be a Fixnum or a String. If numeric, it should be
- *  one of the operating system specific constants (O_RDONLY,
- *  O_WRONLY, O_RDWR, O_APPEND and so on). See man open(2) for
- *  more information.
- *
- *  If the mode is given as a String, it must be one of the
- *  values listed in the following table.
- *
- *    Mode |  Meaning
- *    -----+--------------------------------------------------------
- *    "r"  |  Read-only, starts at beginning of file  (default mode).
- *    -----+--------------------------------------------------------
- *    "r+" |  Read-write, starts at beginning of file.
- *    -----+--------------------------------------------------------
- *    "w"  |  Write-only, truncates existing file 
- *         |  to zero length or creates a new file for writing.
- *    -----+--------------------------------------------------------
- *    "w+" |  Read-write, truncates existing file to zero length
- *         |  or creates a new file for reading and writing.
- *    -----+--------------------------------------------------------
- *    "a"  |  Write-only, starts at end of file if file exists,
- *         |  otherwise creates a new file for writing.
- *    -----+--------------------------------------------------------
- *    "a+" |  Read-write, starts at end of file if file exists,
- *         |  otherwise creates a new file for reading and 
- *         |  writing.
- *    -----+--------------------------------------------------------
- *     "b" |  (DOS/Windows only) Binary file mode (may appear with 
- *         |  any of the key letters listed above).
- *
- *
- *  The global constant ARGF (also accessible as $<) provides an
- *  IO-like stream which allows access to all files mentioned on the
- *  command line (or STDIN if no files are mentioned). ARGF provides
- *  the methods <code>#path</code> and <code>#filename</code> to access
- *  the name of the file currently being read.

-# 
-# The following particular features are also provided:
-# - encode into lines of a given length (#b64encode)
-# - decode the special format specified in RFC2047 for the
-#   representation of email headers (decode_b)
-#
-# == Example
-#
-# A simple encoding and decoding.

-#                         # -> "Send reinforcements"
-#
-# The purpose of using base64 to encode data is that it translates any

-# == Overview
-#
-# The Benchmark module provides methods for benchmarking Ruby code, giving
-# detailed reports on the time taken for each task.
-#
-
-# The Benchmark module provides methods to measure and report the time
-# used to execute Ruby code.
-#
-# * Measure the time to construct the string given by the expression
-#   <tt>"a"*1_000_000</tt>:
-#
-#       require 'benchmark'
-#
-#       puts Benchmark.measure { "a"*1_000_000 }
-# 
-#   On my machine (FreeBSD 3.2 on P5, 100MHz) this generates:
-# 
-#       1.166667   0.050000   1.216667 (  0.571355)
-# 
-#   This report shows the user CPU time, system CPU time, the sum of
-#   the user and system CPU times, and the elapsed real time. The unit
-#   of time is seconds.
-# 
-# * Do some experiments sequentially using the #bm method:
-#
-#       require 'benchmark'
-#
-#       n = 50000
-#       Benchmark.bm do |x|
-#         x.report { for i in 1..n; a = "1"; end }
-#         x.report { n.times do   ; a = "1"; end }
-#         x.report { 1.upto(n) do ; a = "1"; end }
-#       end
-# 
-#   The result:
-#
-#              user     system      total        real
-#          1.033333   0.016667   1.016667 (  0.492106)
-#          1.483333   0.000000   1.483333 (  0.694605)
-#          1.516667   0.000000   1.516667 (  0.711077)
-#
-# * Continuing the previous example, put a label in each report:
-#
-#       require 'benchmark'
-#
-#       n = 50000
-#       Benchmark.bm(7) do |x|
-#         x.report("for:")   { for i in 1..n; a = "1"; end }
-#         x.report("times:") { n.times do   ; a = "1"; end }
-#         x.report("upto:")  { 1.upto(n) do ; a = "1"; end }
-#       end
-# 
-# The result:
-# 
-#                     user     system      total        real
-#        for:     1.050000   0.000000   1.050000 (  0.503462)
-#        times:   1.533333   0.016667   1.550000 (  0.735473)
-#        upto:    1.500000   0.016667   1.516667 (  0.711239)
-# 
-#
-# * The times for some benchmarks depend on the order in which items
-#   are run.  These differences are due to the cost of memory
-#   allocation and garbage collection. To avoid these discrepancies,
-#   the #bmbm method is provided.  For example, to compare ways to
-#   sort an array of floats:
-#
-#       require 'benchmark'
-#       
-#       array = (1..1000000).map { rand }
-#       
-#       Benchmark.bmbm do |x|
-#         x.report("sort!") { array.dup.sort! }
-#         x.report("sort")  { array.dup.sort  }
-#       end
-# 
-#   The result:
-# 
-#        Rehearsal -----------------------------------------
-#        sort!  11.928000   0.010000  11.938000 ( 12.756000)
-#        sort   13.048000   0.020000  13.068000 ( 13.857000)
-#        ------------------------------- total: 25.006000sec
-#        
-#                    user     system      total        real
-#        sort!  12.959000   0.010000  12.969000 ( 13.793000)
-#        sort   12.007000   0.000000  12.007000 ( 12.791000)
-#
-#
-# * Report statistics of sequential experiments with unique labels,
-#   using the #benchmark method:
-#
-#       require 'benchmark'
-#
-#       n = 50000
-#       Benchmark.benchmark(" "*7 + CAPTION, 7, FMTSTR, ">total:", ">avg:") do |x|
-#         tf = x.report("for:")   { for i in 1..n; a = "1"; end }
-#         tt = x.report("times:") { n.times do   ; a = "1"; end }
-#         tu = x.report("upto:")  { 1.upto(n) do ; a = "1"; end }
-#         [tf+tt+tu, (tf+tt+tu)/3]
-#       end
-# 
-#   The result:

-# 
-# == Overview
-#
-# The Common Gateway Interface (CGI) is a simple protocol
-# for passing an HTTP request from a web server to a
-# standalone program, and returning the output to the web
-# browser.  Basically, a CGI program is called with the
-# parameters of the request passed in either in the
-# environment (GET) or via $stdin (POST), and everything
-# it prints to $stdout is returned to the client.
-# 
-# This file holds the +CGI+ class.  This class provides
-# functionality for retrieving HTTP request parameters,
-# managing cookies, and generating HTML output.  See the
-# class documentation for more details and examples of use.
-#
-# The file cgi/session.rb provides session management
-# functionality; see that file for more details.
-#
-# See http://www.w3.org/CGI/ for more information on the CGI
-# protocol.

-# CGI class.  See documentation for the file cgi.rb for an overview
-# of the CGI protocol.
-#
-# == Introduction
-#
-# CGI is a large class, providing several categories of methods, many of which
-# are mixed in from other modules.  Some of the documentation is in this class,
-# some in the modules CGI::QueryExtension and CGI::HtmlExtension.  See
-# CGI::Cookie for specific information on handling cookies, and cgi/session.rb
-# (CGI::Session) for information on sessions.
-#
-# For queries, CGI provides methods to get at environmental variables,
-# parameters, cookies, and multipart request data.  For responses, CGI provides
-# methods for writing output and generating HTML.
-#
-# Read on for more details.  Examples are provided at the bottom.
-#
-# == Queries
-#
-# The CGI class dynamically mixes in parameter and cookie-parsing
-# functionality,  environmental variable access, and support for
-# parsing multipart requests (including uploaded files) from the
-# CGI::QueryExtension module.
-#
-# === Environmental Variables
-#
-# The standard CGI environmental variables are available as read-only
-# attributes of a CGI object.  The following is a list of these variables:
-#
-#
-#   AUTH_TYPE               HTTP_HOST          REMOTE_IDENT
-#   CONTENT_LENGTH          HTTP_NEGOTIATE     REMOTE_USER
-#   CONTENT_TYPE            HTTP_PRAGMA        REQUEST_METHOD
-#   GATEWAY_INTERFACE       HTTP_REFERER       SCRIPT_NAME
-#   HTTP_ACCEPT             HTTP_USER_AGENT    SERVER_NAME
-#   HTTP_ACCEPT_CHARSET     PATH_INFO          SERVER_PORT
-#   HTTP_ACCEPT_ENCODING    PATH_TRANSLATED    SERVER_PROTOCOL
-#   HTTP_ACCEPT_LANGUAGE    QUERY_STRING       SERVER_SOFTWARE
-#   HTTP_CACHE_CONTROL      REMOTE_ADDR
-#   HTTP_FROM               REMOTE_HOST
-#
-#
-# For each of these variables, there is a corresponding attribute with the
-# same name, except all lower case and without a preceding HTTP_.  
-# +content_length+ and +server_port+ are integers; the rest are strings.
-#
-# === Parameters
-#
-# The method #params() returns a hash of all parameters in the request as
-# name/value-list pairs, where the value-list is an Array of one or more
-# values.  The CGI object itself also behaves as a hash of parameter names 
-# to values, but only returns a single value (as a String) for each 
-# parameter name.
-#
-# For instance, suppose the request contains the parameter 
-# "favourite_colours" with the multiple values "blue" and "green".  The
-# following behaviour would occur:
-#
-#   cgi.params["favourite_colours"]  # => ["blue", "green"]
-#   cgi["favourite_colours"]         # => "blue"
-#
-# If a parameter does not exist, the former method will return an empty
-# array, the latter an empty string.  The simplest way to test for existence
-# of a parameter is by the #has_key? method.
-#
-# === Cookies
-#
-# HTTP Cookies are automatically parsed from the request.  They are available
-# from the #cookies() accessor, which returns a hash from cookie name to
-# CGI::Cookie object.
-#
-# === Multipart requests
-#
-# If a request's method is POST and its content type is multipart/form-data, 
-# then it may contain uploaded files.  These are stored by the QueryExtension
-# module in the parameters of the request.  The parameter name is the name
-# attribute of the file input field, as usual.  However, the value is not
-# a string, but an IO object, either an IOString for small files, or a
-# Tempfile for larger ones.  This object also has the additional singleton
-# methods:
-#
-# #local_path():: the path of the uploaded file on the local filesystem
-# #original_filename():: the name of the file on the client computer
-# #content_type():: the content type of the file
-#
-# == Responses
-#
-# The CGI class provides methods for sending header and content output to
-# the HTTP client, and mixes in methods for programmatic HTML generation
-# from CGI::HtmlExtension and CGI::TagMaker modules.  The precise version of HTML
-# to use for HTML generation is specified at object creation time.
-#
-# === Writing output
-#
-# The simplest way to send output to the HTTP client is using the #out() method.
-# This takes the HTTP headers as a hash parameter, and the body content
-# via a block.  The headers can be generated as a string using the #header()
-# method.  The output stream can be written directly to using the #print()
-# method.
-#
-# === Generating HTML
-#
-# Each HTML element has a corresponding method for generating that
-# element as a String.  The name of this method is the same as that
-# of the element, all lowercase.  The attributes of the element are 
-# passed in as a hash, and the body as a no-argument block that evaluates
-# to a String.  The HTML generation module knows which elements are
-# always empty, and silently drops any passed-in body.  It also knows
-# which elements require matching closing tags and which don't.  However,
-# it does not know what attributes are legal for which elements.
-#
-# There are also some additional HTML generation methods mixed in from
-# the CGI::HtmlExtension module.  These include individual methods for the
-# different types of form inputs, and methods for elements that commonly
-# take particular attributes where the attributes can be directly specified
-# as arguments, rather than via a hash.
-#
-# == Examples of use
-# 
-# === Get form values
-# 
-#   require "cgi"
-#   cgi = CGI.new
-#   value = cgi['field_name']   # <== value string for 'field_name'
-#     # if not 'field_name' included, then return "".
-#   fields = cgi.keys            # <== array of field names
-# 
-#   # returns true if form has 'field_name'
-#   cgi.has_key?('field_name')
-#   cgi.has_key?('field_name')
-#   cgi.include?('field_name')
-# 
-# CAUTION! cgi['field_name'] returned an Array with the old 
-# cgi.rb(included in ruby 1.6)
-# 
-# === Get form values as hash
-# 
-#   require "cgi"
-#   cgi = CGI.new
-#   params = cgi.params
-# 
-# cgi.params is a hash.
-# 
-#   cgi.params['new_field_name'] = ["value"]  # add new param
-#   cgi.params['field_name'] = ["new_value"]  # change value
-#   cgi.params.delete('field_name')           # delete param
-#   cgi.params.clear                          # delete all params
-# 
-# 
-# === Save form values to file
-# 
-#   require "pstore"
-#   db = PStore.new("query.db")
-#   db.transaction do
-#     db["params"] = cgi.params
-#   end
-# 
-# 
-# === Restore form values from file
-# 
-#   require "pstore"
-#   db = PStore.new("query.db")
-#   db.transaction do
-#     cgi.params = db["params"]
-#   end
-# 
-# 
-# === Get multipart form values
-# 
-#   require "cgi"
-#   cgi = CGI.new
-#   value = cgi['field_name']   # <== value string for 'field_name'
-#   value.read                  # <== body of value
-#   value.local_path            # <== path to local file of value
-#   value.original_filename     # <== original filename of value
-#   value.content_type          # <== content_type of value
-# 
-# and value has StringIO or Tempfile class methods.
-# 
-# === Get cookie values
-# 
-#   require "cgi"
-#   cgi = CGI.new
-#   values = cgi.cookies['name']  # <== array of 'name'
-#     # if not 'name' included, then return [].
-#   names = cgi.cookies.keys      # <== array of cookie names
-# 
-# and cgi.cookies is a hash.
-# 
-# === Get cookie objects
-# 
-#   require "cgi"
-#   cgi = CGI.new
-#   for name, cookie in cgi.cookies
-#     cookie.expires = Time.now + 30
-#   end
-#   cgi.out("cookie" => cgi.cookies) {"string"}
-# 
-#   cgi.cookies # { "name1" => cookie1, "name2" => cookie2, ... }
-# 
-#   require "cgi"
-#   cgi = CGI.new
-#   cgi.cookies['name'].expires = Time.now + 30
-#   cgi.out("cookie" => cgi.cookies['name']) {"string"}
-# 
-# === Print http header and html string to $DEFAULT_OUTPUT ($>)
-# 
-#   require "cgi"
-#   cgi = CGI.new("html3")  # add HTML generation methods
-#   cgi.out() do
-#     cgi.html() do
-#       cgi.head{ cgi.title{"TITLE"} } +
-#       cgi.body() do
-#         cgi.form() do
-#           cgi.textarea("get_text") +
-#           cgi.br +
-#           cgi.submit
-#         end +
-#         cgi.pre() do
-#           CGI::escapeHTML(
-#             "params: " + cgi.params.inspect + "\n" +
-#             "cookies: " + cgi.cookies.inspect + "\n" +

-# Information associated with the session is stored
-# on the server between requests.  A session id is passed between client
-# and server with every request and response, transparently
-# to the user.  This adds state information to the otherwise stateless
-# HTTP request/response protocol.
-#
-# See the documentation to the +CGI::Session+ class for more details
-# and examples of usage.  See cgi.rb for the +CGI+ class itself.

-class CGI
-
-  # Class representing an HTTP session.  See documentation for the file 
-  # cgi/session.rb for an introduction to HTTP sessions.
-  #
-  # == Lifecycle
-  #
-  # A CGI::Session instance is created from a CGI object.  By default,
-  # this CGI::Session instance will start a new session if none currently
-  # exists, or continue the current session for this client if one does
-  # exist.  The +new_session+ option can be used to either always or
-  # never create a new session.  See #new() for more details.
-  #
-  # #delete() deletes a session from session storage.  It
-  # does not however remove the session id from the client.  If the client
-  # makes another request with the same id, the effect will be to start
-  # a new session with the old session's id.
-  #
-  # == Setting and retrieving session data.
-  #
-  # The Session class associates data with a session as key-value pairs.
-  # This data can be set and retrieved by indexing the Session instance 
-  # using '[]', much the same as hashes (although other hash methods
-  # are not supported).
-  #
-  # When session processing has been completed for a request, the
-  # session should be closed using the close() method.  This will
-  # store the session's state to persistent storage.  If you want
-  # to store the session's state to persistent storage without
-  # finishing session processing for this request, call the update()
-  # method.
-  #
-  # == Storing session state
-  #
-  # The caller can specify what form of storage to use for the session's 
-  # data with the +database_manager+ option to CGI::Session::new.  The
-  # following storage classes are provided as part of the standard library:
-  #
-  # CGI::Session::FileStore:: stores data as plain text in a flat file.  Only 
-  #                           works with String data.  This is the default 
-  #                           storage type.
-  # CGI::Session::MemoryStore:: stores data in an in-memory hash.  The data 
-  #                             only persists for as long as the current ruby 
-  #                             interpreter instance does.
-  # CGI::Session::PStore:: stores data in Marshalled format.  Provided by
-  #                        cgi/session/pstore.rb.  Supports data of any type, 
-  #                        and provides file-locking and transaction support.
-  #
-  # Custom storage types can also be created by defining a class with 
-  # the following methods:
-  #
-  #    new(session, options)
-  #    restore  # returns hash of session data.
-  #    update
-  #    close
-  #    delete
-  #
-  # Changing storage type mid-session does not work.  Note in particular
-  # that by default the FileStore and PStore session data files have the
-  # same name.  If your application switches from one to the other without
-  # making sure that filenames will be different
-  # and clients still have old sessions lying around in cookies, then
-  # things will break nastily!
-  #
-  # == Maintaining the session id.
-  #
-  # Most session state is maintained on the server.  However, a session
-  # id must be passed backwards and forwards between client and server
-  # to maintain a reference to this session state.
-  #
-  # The simplest way to do this is via cookies.  The CGI::Session class
-  # provides transparent support for session id communication via cookies
-  # if the client has cookies enabled.
-  # 
-  # If the client has cookies disabled, the session id must be included
-  # as a parameter of all requests sent by the client to the server.  The
-  # CGI::Session class in conjunction with the CGI class will transparently
-  # add the session id as a hidden input field to all forms generated
-  # using the CGI#form() HTML generation method.  No built-in support is
-  # provided for other mechanisms, such as URL re-writing.  The caller is
-  # responsible for extracting the session id from the session_id 
-  # attribute and manually encoding it in URLs and adding it as a hidden
-  # input to HTML forms created by other mechanisms.  Also, session expiry
-  # is not automatically handled.
-  #
-  # == Examples of use
-  #
-  # === Setting the user's name
-  #
-  #   require 'cgi'
-  #   require 'cgi/session'
-  #   require 'cgi/session/pstore'     # provides CGI::Session::PStore
-  #

-  #       'session_key' => '_rb_sess_id',              # custom session key
-  #       'session_expires' => Time.now + 30 * 60,     # 30 minute timeout 
-  #       'prefix' => 'pstore_sid_')                   # PStore option
-  #   if cgi.has_key?('user_name') and cgi['user_name'] != ''
-  #       # coerce to String: cgi[] returns the 
-  #       # string-like CGI::QueryExtension::Value
-  #       session['user_name'] = cgi['user_name'].to_s
-  #   elsif !session['user_name']

-  #   session.close

-  # === Creating a new session safely

-    #              of the request, or automatically generated for
-    #              a new session.
-    # new_session:: if true, force creation of a new session.  If not set, 
-    #               a new session is only created if none currently
-    #               exists.  If false, a new session is never created,
-    #               and if none currently exists and the +session_id+
-    #               option is not set, an ArgumentError is raised.
-    # database_manager:: the name of the class providing storage facilities
-    #                    for session state persistence.  Built-in support
-    #                    is provided for +FileStore+ (the default),

-    #                    these classes for more details.
-    #
-    # The following options are also recognised, but only apply if the
-    # session id is stored in a cookie.
-    #
-    # session_expires:: the time the current session expires, as a 
-    #                   +Time+ object.  If not set, the session will terminate
-    #                   when the user's browser is closed.
-    # session_domain:: the hostname domain for which this session is valid.
-    #                  If not set, defaults to the hostname of the server.
-    # session_secure:: if +true+, this session will only work over HTTPS.
-    # session_path:: the path for which this session applies.  Defaults
-    #                to the directory of the CGI script.
-    #
-    # +option+ is also passed on to the session storage class initialiser; see

+#      class Complex < Numeric
 #
-# complex.rb implements the Complex class for complex numbers.  Additionally,
-# some methods in other Numeric classes are redefined or added to allow greater
-# interoperability with Complex numbers.
+#   Complex(x, y) --> x + yi
+#   y.im          --> 0 + yi
 #
-# Complex numbers can be created in the following manner:
-# - <tt>Complex(a, b)</tt>
-# - <tt>Complex.polar(radius, theta)</tt>
-#   
-# Additionally, note the following:
-# - <tt>Complex::I</tt> (the mathematical constant <i>i</i>)
-# - <tt>Numeric#im</tt> (e.g. <tt>5.im -> 0+5i</tt>)
+#   Complex::polar
 #
-# The following +Math+ module methods are redefined to handle Complex arguments.
-# They will work as normal with non-Complex arguments.

-#
-# == Overview
-#
-# This file provides two classes for working with
-# dates and times.
-#
-# The first class, Date, represents dates. 
-# It works with years, months, weeks, and days.
-# See the Date class documentation for more details.
-#
-# The second, DateTime, extends Date to include hours,
-# minutes, seconds, and fractions of a second.  It
-# provides basic support for time zones.  See the
-# DateTime class documentation for more details.
-#
-# === Ways of calculating the date.
-#
-# In common usage, the date is reckoned in years since or
-# before the Common Era (CE/BCE, also known as AD/BC), then
-# as a month and day-of-the-month within the current year.
-# This is known as the *Civil* *Date*, and abbreviated
-# as +civil+ in the Date class.
-#
-# Instead of year, month-of-the-year,  and day-of-the-month,
-# the date can also be reckoned in terms of year and
-# day-of-the-year.  This is known as the *Ordinal* *Date*,
-# and is abbreviated as +ordinal+ in the Date class.  (Note
-# that referring to this as the Julian date is incorrect.)
-#
-# The date can also be reckoned in terms of year, week-of-the-year,
-# and day-of-the-week.  This is known as the *Commercial*
-# *Date*, and is abbreviated as +commercial+ in the
-# Date class.  The commercial week runs Monday (day-of-the-week
-# 1) to Sunday (day-of-the-week 7), in contrast to the civil
-# week which runs Sunday (day-of-the-week 0) to Saturday
-# (day-of-the-week 6).  The first week of the commercial year
-# starts on the Monday on or before January 1, and the commercial
-# year itself starts on this Monday, not January 1.
-#
-# For scientific purposes, it is convenient to refer to a date
-# simply as a day count, counting from an arbitrary initial
-# day.  The date first chosen for this was January 1, 4713 BCE.
-# A count of days from this date is the *Julian* *Day* *Number*
-# or *Julian* *Date*, which is abbreviated as +jd+ in the
-# Date class.  This is in local time, and counts from midnight
-# on the initial day.  The stricter usage is in UTC, and counts
-# from midday on the initial day.  This is referred to in the
-# Date class as the *Astronomical* *Julian* *Day* *Number*, and
-# abbreviated as +ajd+.  In the Date class, the Astronomical
-# Julian Day Number includes fractional days.
-#
-# Another absolute day count is the *Modified* *Julian* *Day*
-# *Number*, which takes November 17, 1858 as its initial day.
-# This is abbreviated as +mjd+ in the Date class.  There
-# is also an *Astronomical* *Modified* *Julian* *Day* *Number*,
-# which is in UTC and includes fractional days.  This is
-# abbreviated as +amjd+ in the Date class.  Like the Modified
-# Julian Day Number (and unlike the Astronomical Julian
-# Day Number), it counts from midnight.
-#
-# Alternative calendars such as the Chinese Lunar Calendar,
-# the Islamic Calendar, or the French Revolutionary Calendar
-# are not supported by the Date class; nor are calendars that
-# are based on an Era different from the Common Era, such as
-# the Japanese Imperial Calendar or the Republic of China
-# Calendar.
-#
-# === Calendar Reform
-#
-# The standard civil year is 365 days long.  However, the
-# solar year is fractionally longer than this.  To account
-# for this, a *leap* *year* is occasionally inserted.  This
-# is a year with 366 days, the extra day falling on February 29. 
-# In the early days of the civil calendar, every fourth
-# year without exception was a leap year.  This way of
-# reckoning leap years is the *Julian* *Calendar*.
-#
-# However, the solar year is marginally shorter than 365 1/4
-# days, and so the *Julian* *Calendar* gradually ran slow
-# over the centuries.  To correct this, every 100th year
-# (but not every 400th year) was excluded as a leap year.
-# This way of reckoning leap years, which we use today, is
-# the *Gregorian* *Calendar*.
-#
-# The Gregorian Calendar was introduced at different times
-# in different regions.  The day on which it was introduced
-# for a particular region is the *Day* *of* *Calendar*
-# *Reform* for that region.  This is abbreviated as +sg+
-# (for Start of Gregorian calendar) in the Date class.
-#
-# Two such days are of particular
-# significance.  The first is October 15, 1582, which was
-# the Day of Calendar Reform for Italy and most Catholic
-# countries.  The second is September 14, 1752, which was
-# the Day of Calendar Reform for England and its colonies
-# (including what is now the United States).  These two
-# dates are available as the constants Date::ITALY and
-# Date::ENGLAND, respectively.  (By comparison, Germany and
-# Holland, less Catholic than Italy but less stubborn than
-# England, changed over in 1698; Sweden in 1753; Russia not
-# till 1918, after the Revolution; and Greece in 1923.  Many
-# Orthodox churches still use the Julian Calendar.  A complete
-# list of Days of Calendar Reform can be found at
-# http://www.polysyllabic.com/GregConv.html.)
-#
-# Switching from the Julian to the Gregorian calendar
-# involved skipping a number of days to make up for the
-# accumulated lag, and the later the switch was (or is)
-# done, the more days need to be skipped.  So in 1582 in Italy,
-# 4th October was followed by 15th October, skipping 10 days; in 1752
-# in England, 2nd September was followed by 14th September, skipping
-# 11 days; and if I decided to switch from Julian to Gregorian
-# Calendar this midnight, I would go from 27th July 2003 (Julian)
-# today to 10th August 2003 (Gregorian) tomorrow, skipping
-# 13 days.  The Date class is aware of this gap, and a supposed
-# date that would fall in the middle of it is regarded as invalid.
-#
-# The Day of Calendar Reform is relevant to all date representations
-# involving years.  It is not relevant to the Julian Day Numbers,
-# except for converting between them and year-based representations.
-#
-# In the Date and DateTime classes, the Day of Calendar Reform or
-# +sg+ can be specified a number of ways.  First, it can be as
-# the Julian Day Number of the Day of Calendar Reform.  Second,
-# it can be using the constants Date::ITALY or Date::ENGLAND; these
-# are in fact the Julian Day Numbers of the Day of Calendar Reform
-# of the respective regions.  Third, it can be as the constant
-# Date::JULIAN, which means to always use the Julian Calendar.
-# Finally, it can be as the constant Date::GREGORIAN, which means
-# to always use the Gregorian Calendar.
-#
-# Note: in the Julian Calendar, New Years Day was March 25.  The
-# Date class does not follow this convention.
-#
-# === Time Zones
-#
-# DateTime objects support a simple representation
-# of time zones.  Time zones are represented as an offset
-# from UTC, as a fraction of a day.  This offset is the
-# how much local time is later (or earlier) than UTC.
-# UTC offset 0 is centred on England (also known as GMT). 
-# As you travel east, the offset increases until you
-# reach the dateline in the middle of the Pacific Ocean;
-# as you travel west, the offset decreases.  This offset
-# is abbreviated as +of+ in the Date class.
-#
-# This simple representation of time zones does not take
-# into account the common practice of Daylight Savings
-# Time or Summer Time.
-#
-# Most DateTime methods return the date and the
-# time in local time.  The two exceptions are
-# #ajd() and #amjd(), which return the date and time
-# in UTC time, including fractional days.
-#
-# The Date class does not support time zone offsets, in that
-# there is no way to create a Date object with a time zone.
-# However, methods of the Date class when used by a
-# DateTime instance will use the time zone offset of this
-# instance.
-#
-# == Examples of use
-#
-# === Print out the date of every Sunday between two dates.
-#
-#     def print_sundays(d1, d2)
-#         d1 +=1 while (d1.wday != 0)
-#         d1.step(d2, 7) do |date|
-#             puts "#{Date::MONTHNAMES[date.mon]} #{date.day}"
-#         end
-#     end
-#
-#     print_sundays(Date::civil(2003, 4, 8), Date::civil(2003, 5, 23))
-#
-# === Calculate how many seconds to go till midnight on New Year's Day.
-#
-#     def secs_to_new_year(now = DateTime::now())
-#         new_year = DateTime.new(now.year + 1, 1, 1)
-#         dif = new_year - now
-#         hours, mins, secs, ignore_fractions = Date::day_fraction_to_time(dif)
-#         return hours * 60 * 60 + mins * 60 + secs
-#     end
-#
-#     puts secs_to_new_year()
+#    September 1752
+#  S  M Tu  W Th  F  S
+#        1  2 14 15 16

-#
-# See the documentation to the file date.rb for an overview.
-#
-# Internally, the date is represented as an Astronomical
-# Julian Day Number, +ajd+.  The Day of Calendar Reform, +sg+, is
-# also stored, for conversions to other date formats.  (There
-# is also an +of+ field for a time zone offset, but this
-# is only for the use of the DateTime subclass.)
-#
-# A new Date object is created using one of the object creation
-# class methods named after the corresponding date format, and the
-# arguments appropriate to that date format; for instance,
-# Date::civil() (aliased to Date::new()) with year, month,
-# and day-of-month, or Date::ordinal() with year and day-of-year.
-# All of these object creation class methods also take the
-# Day of Calendar Reform as an optional argument.
-#
-# Date objects are immutable once created.
-#
-# Once a Date has been created, date values
-# can be retrieved for the different date formats supported
-# using instance methods.  For instance, #mon() gives the
-# Civil month, #cwday() gives the Commercial day of the week,
-# and #yday() gives the Ordinal day of the year.  Date values
-# can be retrieved in any format, regardless of what format
-# was used to create the Date instance.
-#
-# The Date class includes the Comparable module, allowing
-# date objects to be compared and sorted, ranges of dates
-# to be created, and so forth.

-# dRuby is a distributed object system for Ruby.  It allows an object in one
-# Ruby process to invoke methods on an object in another Ruby process on the

-# The Ruby standard library contains the core classes of the dRuby package.
-# However, the full package also includes access control lists and the
-# Rinda tuple-space distributed task management system, as well as a 
-# large number of samples.  The full dRuby package can be downloaded from
-# the dRuby home page (see *References*).

-# does not rely on or interoperate with other distributed object
-# systems such as CORBA, RMI, or .NET.
-#
-# dRuby allows methods to be called in one Ruby process upon a Ruby
-# object located in another Ruby process, even on another machine.
-# References to objects can be passed between processes.  Method
-# arguments and return values are dumped and loaded in marshalled
-# format.  All of this is done transparently to both the caller of the
-# remote method and the object that it is called upon.
-#
-# An object in a remote process is locally represented by a
-# DRb::DRbObject instance.  This acts as a sort of proxy for the
-# remote object.  Methods called upon this DRbObject instance are
-# forwarded to its remote object.  This is arranged dynamically at run
-# time.  There are no statically declared interfaces for remote
-# objects, such as CORBA's IDL.
-#
-# dRuby calls made into a process are handled by a DRb::DRbServer
-# instance within that process.  This reconstitutes the method call,
-# invokes it upon the specified local object, and returns the value to
-# the remote caller.  Any object can receive calls over dRuby.  There
-# is no need to implement a special interface, or mixin special
-# functionality.  Nor, in the general case, does an object need to
-# explicitly register itself with a DRbServer in order to receive
-# dRuby calls.
-#
-# One process wishing to make dRuby calls upon another process must
-# somehow obtain an initial reference to an object in the remote
-# process by some means other than as the return value of a remote
-# method call, as there is initially no remote object reference it can
-# invoke a method upon.  This is done by attaching to the server by
-# URI.  Each DRbServer binds itself to a URI such as
-# 'druby://example.com:8787'.  A DRbServer can have an object attached
-# to it that acts as the server's *front* *object*.  A DRbObject can
-# be explicitly created from the server's URI.  This DRbObject's
-# remote object will be the server's front object.  This front object
-# can then return references to other Ruby objects in the DRbServer's
-# process.
-#
-# Method calls made over dRuby behave largely the same as normal Ruby
-# method calls made within a process.  Method calls with blocks are
-# supported, as are raising exceptions.  In addition to a method's
-# standard errors, a dRuby call may also raise one of the
-# dRuby-specific errors, all of which are subclasses of DRb::DRbError.
-#
-# Any type of object can be passed as an argument to a dRuby call or
-# returned as its return value.  By default, such objects are dumped
-# or marshalled at the local end, then loaded or unmarshalled at the
-# remote end.  The remote end therefore receives a copy of the local
-# object, not a distributed reference to it; methods invoked upon this
-# copy are executed entirely in the remote process, not passed on to
-# the local original.  This has semantics similar to pass-by-value.
-#
-# However, if an object cannot be marshalled, a dRuby reference to it
-# is passed or returned instead.  This will turn up at the remote end
-# as a DRbObject instance.  All methods invoked upon this remote proxy
-# are forwarded to the local object, as described in the discussion of
-# DRbObjects.  This has semantics similar to the normal Ruby
-# pass-by-reference.
-# 
-# The easiest way to signal that we want an otherwise marshallable
-# object to be passed or returned as a DRbObject reference, rather
-# than marshalled and sent as a copy, is to include the
-# DRb::DRbUndumped mixin module.
-#
-# dRuby supports calling remote methods with blocks.  As blocks (or
-# rather the Proc objects that represent them) are not marshallable,
-# the block executes in the local, not the remote, context.  Each
-# value yielded to the block is passed from the remote object to the
-# local block, then the value returned by each block invocation is
-# passed back to the remote execution context to be collected, before
-# the collected values are finally returned to the local context as
-# the return value of the method invocation.
-# 
-# == Examples of usage

-# For more dRuby samples, see the +samples+ directory in the full
-# dRuby distribution.

-#
-# This example illustrates returning a reference to an object

-#       logger.log("Goodbye, world!")
-#       logger.log("=== EOT ===")
-#   
-#   end
-#
-# == Security
-#
-# As with all network services, security needs to be considered when
-# using dRuby.  By allowing external access to a Ruby object, you are
-# not only allowing outside clients to call the methods you have
-# defined for that object, but by default to execute arbitrary Ruby
-# code on your server.  Consider the following:
-#
-#    # !!! UNSAFE CODE !!!
-#    ro = DRbObject::new_with_uri("druby://your.server.com:8989")
-#    class << ro
-#      undef :instance_eval  # force call to be passed to remote object
-#    end
-#    ro.instance_eval("`rm -rf *`")
-#
-# The dangers posed by instance_eval and friends are such that a
-# DRbServer should generally be run with $SAFE set to at least 
-# level 1.  This will disable eval() and related calls on strings 
-# passed across the wire.  The sample usage code given above follows 
-# this practice.
-#
-# A DRbServer can be configured with an access control list to
-# selectively allow or deny access from specified IP addresses.  The
-# main druby distribution provides the ACL class for this purpose.  In
-# general, this mechanism should only be used alongside, rather than
-# as a replacement for, a good firewall.
-#
-# == dRuby internals
-#
-# dRuby is implemented using three main components: a remote method
-# call marshaller/unmarshaller; a transport protocol; and an
-# ID-to-object mapper.  The latter two can be directly, and the first
-# indirectly, replaced, in order to provide different behaviour and
-# capabilities.
-#
-# Marshalling and unmarshalling of remote method calls is performed by
-# a DRb::DRbMessage instance.  This uses the Marshal module to dump
-# the method call before sending it over the transport layer, then
-# reconstitute it at the other end.  There is normally no need to
-# replace this component, and no direct way is provided to do so.
-# However, it is possible to implement an alternative marshalling
-# scheme as part of an implementation of the transport layer.
-#
-# The transport layer is responsible for opening client and server
-# network connections and forwarding dRuby request across them.
-# Normally, it uses DRb::DRbMessage internally to manage marshalling
-# and unmarshalling.  The transport layer is managed by
-# DRb::DRbProtocol.  Multiple protocols can be installed in
-# DRbProtocol at the one time; selection between them is determined by
-# the scheme of a dRuby URI.  The default transport protocol is
-# selected by the scheme 'druby:', and implemented by
-# DRb::DRbTCPSocket.  This uses plain TCP/IP sockets for
-# communication.  An alternative protocol, using UNIX domain sockets,
-# is implemented by DRb::DRbUNIXSocket in the file drb/unix.rb, and
-# selected by the scheme 'drbunix:'.  A sample implementation over
-# HTTP can be found in the samples accompanying the main dRuby
-# distribution.
-#
-# The ID-to-object mapping component maps dRuby object ids to the
-# objects they refer to, and vice versa.  The implementation to use
-# can be specified as part of a DRb::DRbServer's configuration.  The
-# default implementation is provided by DRb::DRbIdConv.  It uses an
-# object's ObjectSpace id as its dRuby id.  This means that the dRuby
-# reference to that object only remains meaningful for the lifetime of
-# the object's process and the lifetime of the object within that
-# process.  A modified implementation is provided by DRb::TimerIdConv
-# in the file drb/timeridconv.rb.  This implementation retains a local
-# reference to all objects exported over dRuby for a configurable
-# period of time (defaulting to ten minutes), to prevent them being
-# garbage-collected within this time.  Another sample implementation
-# is provided in sample/name.rb in the main dRuby distribution.  This
-# allows objects to specify their own id or "name".  A dRuby reference
-# can be made persistent across processes by having each process
-# register an object using the same dRuby name.

-  # Module managing the underlying network protocol(s) used by drb.
-  #
-  # By default, drb uses the DRbTCPSocket protocol.  Other protocols
-  # can be defined.  A protocol must define the following class methods:
-  #
-  #   [open(uri, config)] Open a client connection to the server at +uri+,
-  #                       using configuration +config+.  Return a protocol
-  #                       instance for this connection.
-  #   [open_server(uri, config)] Open a server listening at +uri+,
-  #                              using configuration +config+.  Return a
-  #                              protocol instance for this listener.
-  #   [uri_option(uri, config)] Take a URI, possibly containing an option
-  #                             component (e.g. a trailing '?param=val'), 
-  #                             and return a [uri, option] tuple.
-  #
-  # All of these methods should raise a DRbBadScheme error if the URI 
-  # does not identify the protocol they support (e.g. "druby:" for
-  # the standard Ruby protocol).  This is how the DRbProtocol module,
-  # given a URI, determines which protocol implementation serves that
-  # protocol.
-  #
-  # The protocol instance returned by #open_server must have the
-  # following methods:
-  #
-  # [accept] Accept a new connection to the server.  Returns a protocol
-  #          instance capable of communicating with the client.
-  # [close] Close the server connection.
-  # [uri] Get the URI for this server.
-  #
-  # The protocol instance returned by #open must have the following methods:
-  #
-  # [send_request (ref, msg_id, arg, b)] 
-  #      Send a request to +ref+ with the given message id and arguments.
-  #      This is most easily implemented by calling DRbMessage.send_request,
-  #      providing a stream that sits on top of the current protocol.
-  # [recv_reply]
-  #      Receive a reply from the server and return it as a [success-boolean,
-  #      reply-value] pair.  This is most easily implemented by calling
-  #      DRb.recv_reply, providing a stream that sits on top of the 
-  #      current protocol.
-  # [alive?]

-#
-# +fileutils+ contains all or nearly all the same functionality and more, and is a recommended

-#
-# When you

-# = generator.rb: convert an internal iterator to an external one
-#
-# Copyright (c) 2001,2003 Akinori MUSHA <knu@iDaemons.org>
-#
-# All rights reserved.  You can redistribute and/or modify it under
-# the same terms as Ruby.
-#
-# == Overview
-#
-# This library provides the Generator class, which converts an
-# internal iterator (i.e. an Enumerable object) to an external
-# iterator.  In that form, you can roll many iterators independently.
-#
-# The SyncEnumerator class, which is implemented using Generator,
-# makes it easy to roll many Enumerable objects synchronously.
-#
-# See the respective classes for examples of usage.
-
-
-#
-# Generator converts an internal iterator (i.e. an Enumerable object)
-# to an external iterator.
-#
-# Note that it is not very fast since it is implemented using
-# continuations, which are currently slow.
-#
-# == Example
-#
-#   require 'generator'
-#
-#   # Generator from an Enumerable object
-#   g = Generator.new(['A', 'B', 'C', 'Z'])
-#
-#   while g.next?
-#     puts g.next
-#   end
-#
-#   # Generator from a block
-#   g = Generator.new { |g|
-#     for i in 'A'..'C'
-#       g.yield i
-#     end
-#
-#     g.yield 'Z'
-#   }
-#
-#   # The same result as above
-#   while g.next?
-#     puts g.next
-#   end

-#
-# +GServer+ implements a generic server, featuring thread pool management, simple logging, and
-# multi-server management.  See <tt>xmlrpc/httpserver.rb</tt> in the Ruby standard library for
-# an example of +GServer+ in action.
-#
-# Any kind of application-level server can be implemented using this class.  It accepts
-# multiple simultaneous connections from clients, up to an optional maximum number.  Several
-# _services_ (i.e. one service per TCP port) can be run simultaneously, and stopped at any time
-# through the class method <tt>GServer.stop(port)</tt>.  All the threading issues are handled,
-# saving you the effort.  All events are optionally logged, but you can provide your own event
-# handlers if you wish.
-#
-# === Example
-#
-# Using +GServer+ is simple.  Below we implement a simple time server, run it, query it, and
-# shut it down.  Try this code in +irb+:
-#
-#   require 'gserver'
-#
-#   #
-#   # A server that returns the time in seconds since 1970.
-#   # 
-#   class TimeServer < GServer
-#     def initialize(port=10001, *args)
-#       super(port, *args)
-#     end
-#     def serve(io)
-#       io.puts(Time.now.to_i)
-#     end
-#   end
-#
-#   # Run the server with logging enabled (it's a separate thread).
-#   server = TimeServer.new
-#   server.audit = true                  # Turn logging on.
-#   server.start 
-#
-#   # *** Now point your browser to http://localhost:10001 to see it working ***
-#
-#   # See if it's still running. 
-#   GServer.in_service?(10001)           # -> true
-#   server.stopped?                      # -> false
-#
-#   # Shut the server down gracefully.
-#   server.shutdown
-#   
-#   # Alternatively, stop it immediately.
-#   GServer.stop(10001)
-#   # or, of course, "server.stop".
-#
-# All the business of accepting connections and exception handling is taken care of.  All we
-# have to do is implement the method that actually serves the client.
-#
-# === Advanced
-#
-# As the example above shows, the way to use +GServer+ is to subclass it to create a specific
-# server, overriding the +serve+ method.  You can override other methods as well if you wish,
-# perhaps to collect statistics, or emit more detailed logging.
-#
-#   connecting
-#   disconnecting
-#   starting
-#   stopping
-#
-# The above methods are only called if auditing is enabled.
-#
-# You can also override +log+ and +error+ if, for example, you wish to use a more sophisticated
-# logging system.

-#

-
-#
-# == Description
-#
-# The Logger class provides a simple but sophisticated logging utility that
-# anyone can use because it's included in the Ruby 1.8.x standard library.
-# For more advanced logging, see the "Log4r" package on the RAA.
-#
-# The HOWTOs below give a code-based overview of Logger's usage, but the basic
-# concept is as follows.  You create a Logger object (output to a file or
-# elsewhere), and use it to log messages.  The messages will have varying
-# levels (+info+, +error+, etc), reflecting their varying importance.  The
-# levels, and their meanings, are:
-#
-# +FATAL+:: an unhandleable error that results in a program crash
-# +ERROR+:: a handleable error condition
-# +WARN+::  a warning
-# +INFO+::  generic (useful) information about system operation
-# +DEBUG+:: low-level information for developers
-#
-# So each message has a level, and the Logger itself has a level, which acts
-# as a filter, so you can control the amount of information emitted from the
-# logger without having to remove actual messages.
-#
-# For instance, in a production system, you may have your logger(s) set to
-# +INFO+ (or +WARN+ if you don't want the log files growing large with
-# repetitive information).  When you are developing it, though, you probably
-# want to know about the program's internal state, and would set them to
-# +DEBUG+.
-#
-# === Example
-#
-# A simple example demonstrates the above explanation:
-#
-#   log = Logger.new(STDOUT)
-#   log.level = Logger::WARN
-#
-#   log.debug("Created logger")
-#   log.info("Program started")
-#   log.warn("Nothing to do!")
-#
-#   begin
-#     File.each_line(path) do |line|
-#       unless line =~ /^(\w+) = (.*)$/
-#         log.error("Line in wrong format: #{line}")
-#       end
-#     end
-#   rescue => err
-#     log.fatal("Caught exception; exiting")
-#     log.fatal(err)
-#   end
-#
-# Because the Logger's level is set to +WARN+, only the warning, error, and
-# fatal messages are recorded.  The debug and info messages are silently
-# discarded.
-#
-# === Features
-#
-# There are several interesting features that Logger provides, like
-# auto-rolling of log files, setting the format of log messages, and
-# specifying a program name in conjunction with the message.  The next section
-# shows you how to achieve these things.
-#
-# See http://raa.ruby-lang.org/list.rhtml?name=log4r for Log4r, which contains
-# many advanced features like file-based configuration, a wide range of
-# logging targets, simultaneous logging, and hierarchical logging.
-#
-#
-# == HOWTOs
-#
-# === How to create a logger
-#
-# The options below give you various choices, in more or less increasing
-# complexity.
-#
-# 1. Create a logger which logs messages to STDERR/STDOUT.
-#
-#      logger = Logger.new(STDERR)
-#      logger = Logger.new(STDOUT)
-#
-# 2. Create a logger for the file which has the specified name.
-#
-#      logger = Logger.new('logfile.log')
-#
-# 3. Create a logger for the specified file.
-#
-#      file = File.open('foo.log', File::WRONLY | File::APPEND)
-#      # To create new (and to remove old) logfile, add File::CREAT like;
-#      #   file = open('foo.log', File::WRONLY | File::APPEND | File::CREAT)
-#      logger = Logger.new(file)
-#
-# 4. Create a logger which ages logfile once it reaches a certain size.  Leave
-#    10 "old log files" and each file is about 1,024,000 bytes.
-#
-#      logger = Logger.new('foo.log', 10, 1024000)
-#
-# 5. Create a logger which ages logfile daily/weekly/monthly.
-#
-#      logger = Logger.new('foo.log', 'daily')
-#      logger = Logger.new('foo.log', 'weekly')
-#      logger = Logger.new('foo.log', 'monthly')
-#
-# === How to log a message
-#
-# Notice the different methods (+fatal+, +error+, +info+) being used to log
-# messages of various levels.  Other methods in this family are +warn+ and
-# +debug+.  +add+ is used below to log a message of an arbitrary (perhaps
-# dynamic) level.
-#
-# 1. Message in block.
-#
-#      logger.fatal { "Argument 'foo' not given." }
-#
-# 2. Message as a string.
-#
-#      logger.error "Argument #{ @foo } mismatch."
-#
-# 3. With progname.
-#
-#      logger.info('initialize') { "Initializing..." }
-#
-# 4. With severity.
-#
-#      logger.add(Logger::FATAL) { 'Fatal error!' }
-#
-# === How to close a logger
-#
-#      logger.close
-#
-# === Setting severity threshold
-#
-# 1. Original interface.
-#
-#      logger.level = Logger::WARN
-#
-# 2. Log4r (somewhat) compatible interface.
-#
-#      logger.level = Logger::INFO
-#
-#      DEBUG < INFO < WARN < ERROR < FATAL < UNKNOWN
-#
-#
-# == Format
-#
-# Log messages are rendered in the output stream in a certain format.  The
-# default format and a sample are shown below:
-#
-# Log format:
-#   SeverityID, [Date Time mSec #pid] SeverityLabel -- ProgName: message
-#
-# Log sample:
-#   I, [Wed Mar 03 02:34:24 JST 1999 895701 #19074]  INFO -- Main: info.
-#
-# You may change the date and time format in this manner:
-#
-#   logger.datetime_format = "%Y-%m-%d %H:%M:%S"
-#         # e.g. "2004-01-03 00:54:26"
-#
-# There is currently no supported way to change the overall format, but you may
-# have some luck hacking the Format constant.

-  #
-  #   Logger.new(name, shift_age = 7, shift_size = 1048576)
-  #   Logger.new(name, shift_age = 'weekly')
-  #
-  # === Args
-  #
-  # +logdev+::
-  #   The log device.  This is a filename (String) or IO object (typically
-  #   +STDOUT+, +STDERR+, or an open file).
-  # +shift_age+::
-  #   Number of old log files to keep, *or* frequency of rotation (+daily+,
-  #   +weekly+ or +monthly+).
-  # +shift_size+::
-  #   Maximum logfile size (only applies when +shift_age+ is a number).
-  #
-  # === Description
-  #
-  # Create an instance.  See Logger::LogDevice.new for more information if
-  # required.

-  # === Synopsis
-  #
-  #   Logger#add(severity, message = nil, progname = nil) { ... }
-  #
-  # === Args
-  #
-  # +severity+::
-  #   Severity.  Constants are defined in Logger namespace: +DEBUG+, +INFO+,
-  #   +WARN+, +ERROR+, +FATAL+, or +UNKNOWN+.
-  # +message+::
-  #   The log message.  A String or Exception.
-  # +progname+::
-  #   Program name string.  Can be omitted.  Treated as a message if no +message+ and
-  #   +block+ are given.
-  # +block+::
-  #   Can be omitted.  Called to get a message string if +message+ is nil.
-  #
-  # === Return
-  #
-  # +true+ if successful, +false+ otherwise.
-  #
-  # When the given severity is not high enough (for this particular logger), log
-  # no message, and return +true+.
-  #
-  # === Description
-  #
-  # Log a message if the given severity is high enough.  This is the generic
-  # logging method.  Users will be more inclined to use #debug, #info, #warn,
-  # #error, and #fatal.
-  #
-  # <b>Message format</b>: +message+ can be any object, but it has to be
-  # converted to a String in order to log it.  Generally, +inspect+ is used
-  # if the given object is not a String.
-  # A special case is an +Exception+ object, which will be printed in detail,
-  # including message, class, and backtrace.  See #msg2str for the
-  # implementation if required.
-  #
-  # === Bugs
-  #
-  # * Logfile is not locked.
-  # * Append open does not need to lock file.
-  # * But on the OS which supports multi I/O, records possibly be mixed.

-# The +Matrix+ class represents a mathematical matrix, and provides methods for creating
-# special-case matrices (zero, identity, diagonal, singular, vector), operating on them
-# arithmetically and algebraically, and determining their mathematical properties (trace, rank,
-# inverse, determinant).
-#
-# Note that although matrices should theoretically be rectangular, this is not
-# enforced by the class.
-#
-# Also note that the determinant of integer matrices may be incorrectly calculated unless you
-# also <tt>require 'mathn'</tt>.  This may be fixed in the future.

+#
+#   If you include MonitorMixin and override `initialize', you should

-# Documentation comments:
-#  - All documentation comes from Nutshell.
-#  - MonitorMixin.new_cond appears in the example, but is not documented in
-#    Nutshell.
-#  - All the internals (internal modules Accessible and Initializable, class
-#    ConditionVariable) appear in RDoc.  It might be good to hide them, by
-#    making them private, or marking them :nodoc:, etc.
-#  - The entire example from the RD section at the top is replicated in the RDoc
-#    comment for MonitorMixin.  Does the RD section need to remain?
-#  - RDoc doesn't recognise aliases, so we have mon_synchronize documented, but
-#    not synchronize.
-#  - mon_owner is in Nutshell, but appears as an accessor in a separate module
-#    here, so is hard/impossible to RDoc.  Some other useful accessors
-#    (mon_count and some queue stuff) are also in this module, and don't appear
-#    directly in the RDoc output.
-#  - in short, it may be worth changing the code layout in this file to make the
-#    documentation easier

-  # This class implements the File Transfer Protocol.  If you have used a
-  # command-line FTP program, and are familiar with the commands, you will be
-  # able to use this class easily.  Some extra features are included to take
-  # advantage of Ruby's style and strengths.
-  #
-  # == Example
-  # 
-  #   require 'net/ftp'
-  #
-  # === Example 1
-  #  
-  #   ftp = Net::FTP.new('ftp.netlab.co.jp')
-  #   ftp.login
-  #   files = ftp.chdir('pub/lang/ruby/contrib')
-  #   files = ftp.list('n*')
-  #   ftp.getbinaryfile('nif.rb-0.91.gz', 'nif.gz', 1024)
-  #   ftp.close
-  #
-  # === Example 2
-  #
-  #   Net::FTP.open('ftp.netlab.co.jp') do |ftp|
-  #     ftp.login
-  #     files = ftp.chdir('pub/lang/ruby/contrib')
-  #     files = ftp.list('n*')
-  #     ftp.getbinaryfile('nif.rb-0.91.gz', 'nif.gz', 1024)
-  #   end
-  #
-  # == Major Methods
-  #
-  # The following are the methods most likely to be useful to users:
-  # - FTP.open
-  # - #getbinaryfile
-  # - #gettextfile
-  # - #putbinaryfile
-  # - #puttextfile

-  # == What Is This Library?
-  # 
-  # This library provides your program functions to access WWW
-  # documents via HTTP, Hyper Text Transfer Protocol version 1.1.
-  # For details of HTTP, refer [RFC2616]
-  # (http://www.ietf.org/rfc/rfc2616.txt).
-  # 
-  # == Examples
-  # 
-  # === Getting Document From WWW Server
-  # 
-  # (formal version)
-  # 
-  #     require 'net/http'
-  #     Net::HTTP.start('www.example.com', 80) { |http|
-  #         response = http.get('/index.html')
-  #         puts response.body
-  #     }
-  # 
-  # (shorter version)
-  # 
-  #     require 'net/http'
-  #     Net::HTTP.get_print 'www.example.com', '/index.html'
-  # 
-  #             or
-  # 
-  #     require 'net/http'
-  #     require 'uri'
-  #     Net::HTTP.get_print URI.parse('http://www.example.com/index.html')
-  # 
-  # === Posting Form Data
-  # 
-  #     require 'net/http'
-  #     Net::HTTP.start('some.www.server', 80) { |http|
-  #         response = http.post('/cgi-bin/search.rb', 'query=ruby')
-  #     }
-  # 
-  # === Accessing via Proxy
-  # 
-  # Net::HTTP.Proxy creates http proxy class. It has same
-  # methods of Net::HTTP but its instances always connect to
-  # proxy, instead of given host.
-  # 
-  #     require 'net/http'
-  # 
-  #     proxy_addr = 'your.proxy.host'
-  #     proxy_port = 8080
-  #             :
-  #     Net::HTTP::Proxy(proxy_addr, proxy_port).start('www.example.com') {|http|
-  #         # always connect to your.proxy.addr:8080
-  #             :
-  #     }
-  # 
-  # Since Net::HTTP.Proxy returns Net::HTTP itself when proxy_addr is nil,
-  # there's no need to change code if there's proxy or not.
-  # 
-  # There are two additional parameters in Net::HTTP.Proxy which allow to
-  # specify proxy user name and password:
-  # 
-  #     Net::HTTP::Proxy(proxy_addr, proxy_port, proxy_user = nil, proxy_pass = nil)
-  # 
-  # You may use them to work with authorization-enabled proxies:
-  # 
-  #     require 'net/http'
-  #     require 'uri'
-  #     
-  #     proxy_host = 'your.proxy.host'
-  #     proxy_port = 8080
-  #     uri = URI.parse(ENV['http_proxy'])
-  #     proxy_user, proxy_pass = uri.userinfo.split(/:/) if uri.userinfo
-  #     Net::HTTP::Proxy(proxy_host, proxy_port,
-  #                      proxy_user, proxy_pass).start('www.example.com') {|http|
-  #       # always connect to your.proxy.addr:8080 using specified username and password
-  #             :
-  #     }
-  #
-  # Note that net/http never rely on HTTP_PROXY environment variable.
-  # If you want to use proxy, set it explicitly.
-  # 
-  # === Following Redirection
-  # 
-  #     require 'net/http'
-  #     require 'uri'
-  # 
-  #     def fetch( uri_str, limit = 10 )
-  #       # You should choose better exception. 
-  #       raise ArgumentError, 'HTTP redirect too deep' if limit == 0
-  # 
-  #       response = Net::HTTP.get_response(URI.parse(uri_str))
-  #       case response
-  #       when Net::HTTPSuccess     then response
-  #       when Net::HTTPRedirection then fetch(response['location'], limit - 1)
-  #       else
-  #         response.error!
-  #       end
-  #     end
-  # 
-  #     print fetch('http://www.ruby-lang.org')
-  # 
-  # Net::HTTPSuccess and Net::HTTPRedirection is a HTTPResponse class.
-  # All HTTPResponse objects belong to its own response class which
-  # indicate HTTP result status. For details of response classes,
-  # see section "HTTP Response Classes".
-  # 
-  # === Basic Authentication
-  # 
-  #     require 'net/http'
-  # 
-  #     Net::HTTP.start('www.example.com') {|http|
-  #       req = Net::HTTP::Get.new('/secret-page.html')
-  #       req.basic_auth 'account', 'password'
-  #       response = http.request(req)
-  #       print response.body
-  #     }
-  # 
-  # === HTTP Response Classes
-  #
-  # TODO: write me.
-  # 
-  # == Switching Net::HTTP versions
-  # 
-  # You can use net/http.rb 1.1 features (bundled with Ruby 1.6)
-  # by calling HTTP.version_1_1. Calling Net::HTTP.version_1_2
-  # allows you to use 1.2 features again.
-  # 
-  #     # example
-  #     Net::HTTP.start { |http1| ...(http1 has 1.2 features)... }
-  # 
-  #     Net::HTTP.version_1_1
-  #     Net::HTTP.start { |http2| ...(http2 has 1.1 features)... }
-  # 
-  #     Net::HTTP.version_1_2
-  #     Net::HTTP.start { |http3| ...(http3 has 1.2 features)... }

-  #
-  # Net::IMAP implements Internet Message Access Protocol (IMAP) client
-  # functionality.  The protocol is described in [IMAP].
-  #
-  # == IMAP Overview
-  #
-  # An IMAP client connects to a server, and then authenticates
-  # itself using either #authenticate() or #login().  Having
-  # authenticated itself, there is a range of commands
-  # available to it.  Most work with mailboxes, which may be
-  # arranged in an hierarchical namespace, and each of which
-  # contains zero or more messages.  How this is implemented on
-  # the server is implementation-dependent; on a UNIX server, it
-  # will frequently be implemented as a files in mailbox format
-  # within a hierarchy of directories.
-  #
-  # To work on the messages within a mailbox, the client must
-  # first select that mailbox, using either #select() or (for
-  # read-only access) #examine().  Once the client has successfully
-  # selected a mailbox, they enter _selected_ state, and that
-  # mailbox becomes the _current_ mailbox, on which mail-item
-  # related commands implicitly operate.  
-  #
-  # Messages have two sorts of identifiers: message sequence
-  # numbers, and UIDs.  
-  #
-  # Message sequence numbers number messages within a mail box 
-  # from 1 up to the number of items in the mail box.  If new
-  # message arrives during a session, it receives a sequence
-  # number equal to the new size of the mail box.  If messages
-  # are expunged from the mailbox, remaining messages have their
-  # sequence numbers "shuffled down" to fill the gaps.
-  #
-  # UIDs, on the other hand, are permanently guaranteed not to
-  # identify another message within the same mailbox, even if 
-  # the existing message is deleted.  UIDs are required to
-  # be assigned in ascending (but not necessarily sequential)
-  # order within a mailbox; this means that if a non-IMAP client
-  # rearranges the order of mailitems within a mailbox, the
-  # UIDs have to be reassigned.  An IMAP client cannot thus
-  # rearrange message orders.
-  #
-  # == Examples of Usage
-  #
-  # === List sender and subject of all recent messages in the default mailbox
-  #
-  #   imap = Net::IMAP.new('mail.example.com')
-  #   imap.authenticate('LOGIN', 'joe_user', 'joes_password')
-  #   imap.examine('INBOX')
-  #   imap.search(["RECENT"]).each do |message_id|
-  #     envelope = imap.fetch(message_id, "ENVELOPE")[0].attr["ENVELOPE"]
-  #     puts "#{envelope.from[0].name}: \t#{envelope.subject}"
-  #   end
-  #
-  # === Move all messages from April 2003 from "Mail/sent-mail" to "Mail/sent-apr03"
-  #
-  #   imap = Net::IMAP.new('mail.example.com')
-  #   imap.authenticate('LOGIN', 'joe_user', 'joes_password')
-  #   imap.select('Mail/sent-mail')
-  #   if not imap.list('Mail/', 'sent-apr03')
-  #     imap.create('Mail/sent-apr03')
-  #   end
-  #   imap.search(["BEFORE", "30-Apr-2003", "SINCE", "1-Apr-2003"]).each do |message_id|
-  #     imap.copy(message_id, "Mail/sent-apr03")
-  #     imap.store(message_id, "+FLAGS", [:Deleted])
-  #   end
-  #   imap.expunge
-  # 
-  # == Thread Safety
-  #
-  # Net::IMAP supports concurrent threads. For example,
-  # 
-  #   imap = Net::IMAP.new("imap.foo.net", "imap2")
-  #   imap.authenticate("cram-md5", "bar", "password")
-  #   imap.select("inbox")
-  #   fetch_thread = Thread.start { imap.fetch(1..-1, "UID") }
-  #   search_result = imap.search(["BODY", "hello"])
-  #   fetch_result = fetch_thread.value
-  #   imap.disconnect
-  # 
-  # This script invokes the FETCH command and the SEARCH command concurrently.
-  #
-  # == Errors
-  #
-  # An IMAP server can send three different types of responses to indicate
-  # failure:
-  #
-  # NO:: the attempted command could not be successfully completed.  For
-  #      instance, the username/password used for logging in are incorrect;
-  #      the selected mailbox does not exists; etc.  
-  #
-  # BAD:: the request from the client does not follow the server's 
-  #       understanding of the IMAP protocol.  This includes attempting
-  #       commands from the wrong client state; for instance, attempting
-  #       to perform a SEARCH command without having SELECTed a current
-  #       mailbox.  It can also signal an internal server
-  #       failure (such as a disk crash) has occurred.
-  #
-  # BYE:: the server is saying goodbye.  This can be part of a normal
-  #       logout sequence, and can be used as part of a login sequence
-  #       to indicate that the server is (for some reason) unwilling
-  #       to accept our connection.  As a response to any other command,
-  #       it indicates either that the server is shutting down, or that
-  #       the server is timing out the client connection due to inactivity.
-  #
-  # These three error response are represented by the errors
-  # Net::IMAP::NoResponseError, Net::IMAP::BadResponseError, and
-  # Net::IMAP::ByeResponseError, all of which are subclasses of
-  # Net::IMAP::ResponseError.  Essentially, all methods that involve
-  # sending a request to the server can generate one of these errors.
-  # Only the most pertinent instances have been documented below.
-  #
-  # Because the IMAP class uses Sockets for communication, its methods
-  # are also susceptible to the various errors that can occur when
-  # working with sockets.  These are generally represented as
-  # Errno errors.  For instance, any method that involves sending a
-  # request to the server and/or receiving a response from it could
-  # raise an Errno::EPIPE error if the network connection unexpectedly
-  # goes down.  See the socket(7), ip(7), tcp(7), socket(2), connect(2),
-  # and associated man pages.
-  #
-  # Finally, a Net::IMAP::DataFormatError is thrown if low-level data
-  # is found to be in an incorrect format (for instance, when converting
-  # between UTF-8 and UTF-16), and Net::IMAP::ResponseParseError is 
-  # thrown if a server response is non-parseable.

-  # = Net::POP3
-  #
-  # == What is This Library?
-  # 
-  # This library provides functionality for retrieving 
-  # email via POP3, the Post Office Protocol version 3. For details
-  # of POP3, see [RFC1939] (http://www.ietf.org/rfc/rfc1939.txt).
-  # 
-  # == Examples
-  # 
-  # === Retrieving Messages 
-  # 
-  # This example retrieves messages from the server and deletes them 
-  # on the server.
-  #
-  # Messages are written to files named 'inbox/1', 'inbox/2', ....
-  # Replace 'pop.example.com' with your POP3 server address, and
-  # 'YourAccount' and 'YourPassword' with the appropriate account
-  # details.
-  # 
-  #     require 'net/pop'
-  # 
-  #     pop = Net::POP3.new('pop.example.com')
-  #     pop.start('YourAccount', 'YourPassword')             # (1)
-  #     if pop.mails.empty?
-  #       puts 'No mail.'
-  #     else
-  #       i = 0
-  #       pop.each_mail do |m|   # or "pop.mails.each ..."   # (2)
-  #         File.open("inbox/#{i}", 'w') do |f|
-  #           f.write m.pop
-  #         end
-  #         m.delete
-  #         i += 1
-  #       end
-  #       puts "#{pop.mails.size} mails popped."
-  #     end
-  #     pop.finish                                           # (3)
-  # 
-  # 1. Call Net::POP3#start and start POP session.
-  # 2. Access messages by using POP3#each_mail and/or POP3#mails.
-  # 3. Close POP session by calling POP3#finish or use the block form of #start.
-  # 
-  # === Shortened Code
-  # 
-  # The example above is very verbose. You can shorten the code by using
-  # some utility methods. First, the block form of Net::POP3.start can
-  # be used instead of POP3.new, POP3#start and POP3#finish.
-  # 
-  #     require 'net/pop'
-  # 
-  #     Net::POP3.start('pop.example.com', 110,
-  #                     'YourAccount', 'YourPassword') do |pop|
-  #       if pop.mails.empty?
-  #         puts 'No mail.'
-  #       else
-  #         i = 0
-  #         pop.each_mail do |m|   # or "pop.mails.each ..."
-  #           File.open("inbox/#{i}", 'w') do |f|
-  #             f.write m.pop
-  #           end
-  #           m.delete
-  #           i += 1
-  #         end
-  #         puts "#{pop.mails.size} mails popped."
-  #       end
-  #     end
-  # 
-  # POP3#delete_all is an alternative for #each_mail and #delete.
-  # 
-  #     require 'net/pop'
-  # 
-  #     Net::POP3.start('pop.example.com', 110,
-  #                     'YourAccount', 'YourPassword') do |pop|
-  #       if pop.mails.empty?
-  #         puts 'No mail.'
-  #       else
-  #         i = 1
-  #         pop.delete_all do |m|
-  #           File.open("inbox/#{i}", 'w') do |f|
-  #             f.write m.pop
-  #           end
-  #           i += 1
-  #         end
-  #       end
-  #     end
-  # 
-  # And here is an even shorter example.
-  # 
-  #     require 'net/pop'
-  # 
-  #     i = 0
-  #     Net::POP3.delete_all('pop.example.com', 110,
-  #                          'YourAccount', 'YourPassword') do |m|
-  #       File.open("inbox/#{i}", 'w') do |f|
-  #         f.write m.pop
-  #       end
-  #       i += 1
-  #     end
-  # 
-  # === Memory Space Issues
-  # 
-  # All the examples above get each message as one big string.
-  # This example avoids this.
-  # 
-  #     require 'net/pop'
-  # 
-  #     i = 1
-  #     Net::POP3.delete_all('pop.example.com', 110,
-  #                          'YourAccount', 'YourPassword') do |m|
-  #       File.open("inbox/#{i}", 'w') do |f|
-  #         m.pop do |chunk|    # get a message little by little.
-  #           f.write chunk
-  #         end
-  #         i += 1
-  #       end
-  #     end
-  # 
-  # === Using APOP
-  # 
-  # The net/pop library supports APOP authentication.
-  # To use APOP, use the Net::APOP class instead of the Net::POP3 class.
-  # You can use the utility method, Net::POP3.APOP(). For example:
-  # 
-  #     require 'net/pop'
-  # 
-  #     # Use APOP authentication if $isapop == true
-  #     pop = Net::POP3.APOP($is_apop).new('apop.example.com', 110)
-  #     pop.start(YourAccount', 'YourPassword') do |pop|
-  #       # Rest of the code is the same.
-  #     end
-  # 
-  # === Fetch Only Selected Mail Using 'UIDL' POP Command
-  # 
-  # If your POP server provides UIDL functionality,
-  # you can grab only selected mails from the POP server.
-  # e.g.
-  # 
-  #     def need_pop?( id )
-  #       # determine if we need pop this mail...
-  #     end
-  # 
-  #     Net::POP3.start('pop.example.com', 110,
-  #                     'Your account', 'Your password') do |pop|
-  #       pop.mails.select { |m| need_pop?(m.unique_id) }.each do |m|
-  #         do_something(m.pop)
-  #       end
-  #     end
-  # 
-  # The POPMail#unique_id() method returns the unique-id of the message as a
-  # String. Normally the unique-id is a hash of the message.
-  # 
-  class POP3 < Protocol
-
-    Revision = %q$Revision$.split[1]
-
-    #
-    # Class Parameters
-    #
-
-    # The default port for POP3 connections, port 110
-    def POP3.default_port
-      110
-    end
-
-    def POP3.socket_type   #:nodoc: obsolete
-      Net::InternetMessageIO
-    end
-
-    #
-    # Utilities
-    #
-
-    # Returns the APOP class if +isapop+ is true; otherwise, returns
-    # the POP class.  For example:
-    #
-    #     # Example 1
-    #     pop = Net::POP3::APOP($is_apop).new(addr, port)
-    #
-    #     # Example 2
-    #     Net::POP3::APOP($is_apop).start(addr, port) do |pop|
-    #       ....
-    #     end
-    #
-    def POP3.APOP( isapop )
-      isapop ? APOP : POP3
-    end
-
-    # Starts a POP3 session and iterates over each POPMail object,
-    # yielding it to the +block+.
-    # This method is equivalent to:
-    #
-    #     Net::POP3.start(address, port, account, password) do |pop|
-    #       pop.each_mail do |m|
-    #         yield m
-    #       end
-    #     end
-    #
-    # This method raises a POPAuthenticationError if authentication fails.
-    #
-    # === Example
-    #
-    #     Net::POP3.foreach('pop.example.com', 110,
-    #                       'YourAccount', 'YourPassword') do |m|
-    #       file.write m.pop
-    #       m.delete if $DELETE
-    #     end
-    #
-    def POP3.foreach( address, port = nil,
-                      account = nil, password = nil,
-                      isapop = false, &block )  # :yields: message
-      start(address, port, account, password, isapop) {|pop|
-        pop.each_mail(&block)
-      }
-    end
-
-    # Starts a POP3 session and deletes all messages on the server.
-    # If a block is given, each POPMail object is yielded to it before
-    # being deleted.
-    #
-    # This method raises a POPAuthenticationError if authentication fails.
-    #
-    # === Example
-    #
-    #     Net::POP3.delete_all('pop.example.com', 110,
-    #                          'YourAccount', 'YourPassword') do |m|
-    #       file.write m.pop
-    #     end
-    #
-    def POP3.delete_all( address, port = nil,
-                         account = nil, password = nil,
-                         isapop = false, &block )
-      start(address, port, account, password, isapop) {|pop|
-        pop.delete_all(&block)
-      }
-    end
-
-    # Opens a POP3 session, attempts authentication, and quits.
-    #
-    # This method raises POPAuthenticationError if authentication fails.
-    #
-    # === Example: normal POP3
-    #
-    #     Net::POP3.auth_only('pop.example.com', 110,
-    #                         'YourAccount', 'YourPassword')
-    #
-    # === Example: APOP
-    #

-  # == What is This Library?
-  # 
-  # This library provides functionality to send internet
-  # mail via SMTP, the Simple Mail Transfer Protocol. For details of
-  # SMTP itself, see [RFC2821] (http://www.ietf.org/rfc/rfc2821.txt).
-  # 
-  # == What is This Library NOT?
-  # 
-  # This library does NOT provide functions to compose internet mails.
-  # You must create them by yourself. If you want better mail support,
-  # try RubyMail or TMail. You can get both libraries from RAA.
-  # (http://www.ruby-lang.org/en/raa.html)
-  # 
-  # FYI: the official documentation on internet mail is: [RFC2822] (http://www.ietf.org/rfc/rfc2822.txt).
-  # 
-  # == Examples
-  # 
-  # === Sending Messages
-  # 
-  # You must open a connection to an SMTP server before sending messages.
-  # The first argument is the address of your SMTP server, and the second 
-  # argument is the port number. Using SMTP.start with a block is the simplest 
-  # way to do this. This way, the SMTP connection is closed automatically 
-  # after the block is executed.
-  # 
-  #     require 'net/smtp'
-  #     Net::SMTP.start('your.smtp.server', 25) do |smtp|
-  #       # Use the SMTP object smtp only in this block.
-  #     end
-  # 
-  # Replace 'your.smtp.server' with your SMTP server. Normally
-  # your system manager or internet provider supplies a server
-  # for you.
-  # 
-  # Then you can send messages.
-  # 
-  #     msgstr = <<END_OF_MESSAGE
-  #     From: Your Name <your@mail.address>
-  #     To: Destination Address <someone@example.com>
-  #     Subject: test message
-  #     Date: Sat, 23 Jun 2001 16:26:43 +0900
-  #     Message-Id: <unique.message.id.string@example.com>
-  # 
-  #     This is a test message.
-  #     END_OF_MESSAGE
-  # 
-  #     require 'net/smtp'
-  #     Net::SMTP.start('your.smtp.server', 25) do |smtp|
-  #       smtp.send_message msgstr,
-  #                         'your@mail.address',
-  #                         'his_addess@example.com'
-  #     end
-  # 
-  # === Closing the Session
-  # 
-  # You MUST close the SMTP session after sending messages, by calling 
-  # the #finish method:
-  # 
-  #     # using SMTP#finish
-  #     smtp = Net::SMTP.start('your.smtp.server', 25)
-  #     smtp.send_message msgstr, 'from@address', 'to@address'
-  #     smtp.finish
-  # 
-  # You can also use the block form of SMTP.start/SMTP#start.  This closes
-  # the SMTP session automatically:
-  # 
-  #     # using block form of SMTP.start
-  #     Net::SMTP.start('your.smtp.server', 25) do |smtp|
-  #       smtp.send_message msgstr, 'from@address', 'to@address'
-  #     end
-  # 
-  # I strongly recommend this scheme.  This form is simpler and more robust.
-  # 
-  # === HELO domain
-  # 
-  # In almost all situations, you must provide a third argument
-  # to SMTP.start/SMTP#start. This is the domain name which you are on
-  # (the host to send mail from). It is called the "HELO domain".
-  # The SMTP server will judge whether it should send or reject
-  # the SMTP session by inspecting the HELO domain.
-  # 
-  #     Net::SMTP.start('your.smtp.server', 25,
-  #                     'mail.from.domain') { |smtp| ... }
-  # 
-  # === SMTP Authentication
-  # 
-  # The Net::SMTP class supports three authentication schemes;
-  # PLAIN, LOGIN and CRAM MD5.  (SMTP Authentication: [RFC2554])
-  # To use SMTP authentication, pass extra arguments to 
-  # SMTP.start/SMTP#start.
-  # 
-  #     # PLAIN
-  #     Net::SMTP.start('your.smtp.server', 25, 'mail.from.domain',
-  #                     'Your Account', 'Your Password', :plain)
-  #     # LOGIN
-  #     Net::SMTP.start('your.smtp.server', 25, 'mail.from.domain',
-  #                     'Your Account', 'Your Password', :login)
-  # 
-  #     # CRAM MD5
-  #     Net::SMTP.start('your.smtp.server', 25, 'mail.from.domain',
-  #                     'Your Account', 'Your Password', :cram_md5)

-    # WARNING: This method causes serious security holes.
-    # Use this method for only debugging.
-    #
-    # Set an output stream for debug logging.
-    # You must call this before #start.
-    #
-    #   # example
-    #   smtp = Net::SMTP.new(addr, port)
-    #   smtp.set_debug_output $stderr
-    #   smtp.start do |smtp|
-    #     ....

-    # SMTP session control
-    #
-
-    #
-    # Creates a new Net::SMTP object and connects to the server.
-    #
-    # This method is equivalent to:
-    # 
-    #   Net::SMTP.new(address, port).start(helo_domain, account, password, authtype)
-    #
-    # === Example
-    #
-    #     Net::SMTP.start('your.smtp.server') do |smtp|
-    #       smtp.send_message msgstr, 'from@example.com', ['dest@example.com']
-    #     end
-    #
-    # === Block Usage
-    #
-    # If called with a block, the newly-opened Net::SMTP object is yielded
-    # to the block, and automatically closed when the block finishes.  If called
-    # without a block, the newly-opened Net::SMTP object is returned to
-    # the caller, and it is the caller's responsibility to close it when
-    # finished.
-    #
-    # === Parameters
-    #
-    # +address+ is the hostname or ip address of your smtp server.
-    #
-    # +port+ is the port to connect to; it defaults to port 25.
-    #
-    # +helo+ is the _HELO_ _domain_ provided by the client to the
-    # server (see overview comments); it defaults to 'localhost.localdomain'. 
-    #
-    # The remaining arguments are used for SMTP authentication, if required
-    # or desired.  +user+ is the account name; +secret+ is your password
-    # or other authentication token; and +authtype+ is the authentication
-    # type, one of :plain, :login, or :cram_md5.  See the discussion of
-    # SMTP Authentication in the overview notes.
-    #
-    # === Errors
-    #
-    # This method may raise:
-    #
-    # * Net::SMTPAuthenticationError
-    # * Net::SMTPServerBusy
-    # * Net::SMTPSyntaxError
-    # * Net::SMTPFatalError
-    # * Net::SMTPUnknownError
-    # * IOError
-    # * TimeoutError
-    #
-    def SMTP.start( address, port = nil,
-                    helo = 'localhost.localdomain',
-                    user = nil, secret = nil, authtype = nil,
-                    &block) # :yield: smtp
-      new(address, port).start(helo, user, secret, authtype, &block)
-    end
-
-    # +true+ if the SMTP session has been started.
-    def started?
-      @started
-    end
-
-    #
-    # Opens a TCP connection and starts the SMTP session.
-    #
-    # === Parameters
-    #
-    # +helo+ is the _HELO_ _domain_ that you'll dispatch mails from; see
-    # the discussion in the overview notes.
-    #
-    # If both of +user+ and +secret+ are given, SMTP authentication 
-    # will be attempted using the AUTH command.  +authtype+ specifies 
-    # the type of authentication to attempt; it must be one of
-    # :login, :plain, and :cram_md5.  See the notes on SMTP Authentication
-    # in the overview. 
-    #
-    # === Block Usage
-    #
-    # When this methods is called with a block, the newly-started SMTP
-    # object is yielded to the block, and automatically closed after
-    # the block call finishes.  Otherwise, it is the caller's 
-    # responsibility to close the session when finished.
-    #
-    # === Example
-    #
-    # This is very similar to the class method SMTP.start.
-    #
-    #     require 'net/smtp' 
-    #     smtp = Net::SMTP.new('smtp.mail.server', 25)
-    #     smtp.start(helo_domain, account, password, authtype) do |smtp|
-    #       smtp.send_message msgstr, 'from@example.com', ['dest@example.com']
-    #     end 
-    #
-    # The primary use of this method (as opposed to SMTP.start)
-    # is probably to set debugging (#set_debug_output) or ESMTP
-    # (#esmtp=), which must be done before the session is
-    # started.  
-    #
-    # === Errors
-    #
-    # If session has already been started, an IOError will be raised.
-    #
-    # This method may raise:
-    #
-    # * Net::SMTPAuthenticationError
-    # * Net::SMTPServerBusy
-    # * Net::SMTPSyntaxError
-    # * Net::SMTPFatalError
-    # * Net::SMTPUnknownError

-  #
-  # == Net::Telnet
-  #
-  # Provides telnet client functionality.
-  #
-  # This class also has, through delegation, all the methods of a
-  # socket object (by default, a +TCPSocket+, but can be set by the
-  # +Proxy+ option to <tt>new()</tt>).  This provides methods such as
-  # <tt>close()</tt> to end the session and <tt>sysread()</tt> to read
-  # data directly from the host, instead of via the <tt>waitfor()</tt>
-  # mechanism.  Note that if you do use <tt>sysread()</tt> directly
-  # when in telnet mode, you should probably pass the output through
-  # <tt>preprocess()</tt> to extract telnet command sequences.
-  #
-  # == Overview
-  #
-  # The telnet protocol allows a client to login remotely to a user
-  # account on a server and execute commands via a shell.  The equivalent
-  # is done by creating a Net::Telnet class with the +Host+ option
-  # set to your host, calling #login() with your user and password,
-  # issuing one or more #cmd() calls, and then calling #close()
-  # to end the session.  The #waitfor(), #print(), #puts(), and
-  # #write() methods, which #cmd() is implemented on top of, are
-  # only needed if you are doing something more complicated.
-  #
-  # A Net::Telnet object can also be used to connect to non-telnet
-  # services, such as SMTP or HTTP.  In this case, you normally
-  # want to provide the +Port+ option to specify the port to
-  # connect to, and set the +Telnetmode+ option to false to prevent
-  # the client from attempting to interpret telnet command sequences.
-  # Generally, #login() will not work with other protocols, and you
-  # have to handle authentication yourself.
-  #
-  # For some protocols, it will be possible to specify the +Prompt+
-  # option once when you create the Telnet object and use #cmd() calls; 
-  # for others, you will have to specify the response sequence to
-  # look for as the Match option to every #cmd() call, or call
-  # #puts() and #waitfor() directly; for yet others, you will have 
-  # to use #sysread() instead of #waitfor() and parse server 
-  # responses yourself.
-  #
-  # It is worth noting that when you create a new Net::Telnet object,
-  # you can supply a proxy IO channel via the Proxy option.  This
-  # can be used to attach the Telnet object to other Telnet objects,
-  # to already open sockets, or to any read-write IO object.  This
-  # can be useful, for instance, for setting up a test fixture for
-  # unit testing.
-  # 
-  # == Examples
-  # 
-  # === Log in and send a command, echoing all output to stdout
-  # 
-  #   localhost = Net::Telnet::new("Host" => "localhost",
-  #                                "Timeout" => 10,
-  #                                "Prompt" => /[$%#>] \z/n)
-  #   localhost.login("username", "password") { |c| print c }
-  #   localhost.cmd("command") { |c| print c }
-  #   localhost.close
-  # 
-  # 
-  # === Check a POP server to see if you have mail
-  # 
-  #   pop = Net::Telnet::new("Host" => "your_destination_host_here",
-  #                          "Port" => 110,
-  #                          "Telnetmode" => false,
-  #                          "Prompt" => /^\+OK/n)
-  #   pop.cmd("user " + "your_username_here") { |c| print c }
-  #   pop.cmd("pass " + "your_password_here") { |c| print c }
-  #   pop.cmd("list") { |c| print c }
-  #
-  # == References
-  #
-  # There are a large number of RFCs relevant to the Telnet protocol.
-  # RFCs 854-861 define the base protocol.  For a complete listing

-    # +options+ is a hash of options.  The following example lists

-    # 
-    #   host = Net::Telnet::new(
-    #            "Host"       => "localhost",  # default: "localhost"
-    #            "Port"       => 23,           # default: 23
-    #            "Binmode"    => false,        # default: false
-    #            "Output_log" => "output_log", # default: nil (no output)
-    #            "Dump_log"   => "dump_log",   # default: nil (no output)
-    #            "Prompt"     => /[$%#>] \z/n, # default: /[$%#>] \z/n
-    #            "Telnetmode" => true,         # default: true
-    #            "Timeout"    => 10,           # default: 10
-    #              # if ignore timeout then set "Timeout" to false.
-    #            "Waittime"   => 0,            # default: 0
-    #            "Proxy"      => proxy         # default: nil
-    #                            # proxy is Net::Telnet or IO object
-    #          )
-    #
-    # The options have the following meanings:
-    #
-    # Host:: the hostname or IP address of the host to connect to, as a String. 
-    #        Defaults to "localhost".
-    #
-    # Port:: the port to connect to.  Defaults to 23.
-    #
-    # Binmode:: if false (the default), newline substitution is performed.  
-    #           Outgoing LF is
-    #           converted to CRLF, and incoming CRLF is converted to LF.  If
-    #           true, this substitution is not performed.  This value can
-    #           also be set with the #binmode() method.  The 
-    #           outgoing conversion only applies to the #puts() and #print()
-    #           methods, not the #write() method.  The precise nature of
-    #           the newline conversion is also affected by the telnet options
-    #           SGA and BIN.
-    #
-    # Output_log:: the name of the file to write connection status messages
-    #              and all received traffic to.  In the case of a proper
-    #              Telnet session, this will include the client input as
-    #              echoed by the host; otherwise, it only includes server
-    #              responses.  Output is appended verbatim to this file.  
-    #              By default, no output log is kept.
-    #
-    # Dump_log:: as for Output_log, except that output is written in hexdump
-    #            format (16 bytes per line as hex pairs, followed by their
-    #            printable equivalent), with connection status messages
-    #            preceded by '#', sent traffic preceded by '>', and 
-    #            received traffic preceded by '<'.  By default, not dump log
-    #            is kept.
-    #
-    # Prompt:: a regular expression matching the host's command-line prompt
-    #          sequence.  This is needed by the Telnet class to determine
-    #          when the output from a command has finished and the host is
-    #          ready to receive a new command.  By default, this regular
-    #          expression is /[$%#>] \z/n.
-    #
-    # Telnetmode:: a boolean value, true by default.  In telnet mode, 
-    #              traffic received from the host is parsed for special
-    #              command sequences, and these sequences are escaped
-    #              in outgoing traffic sent using #puts() or #print()
-    #              (but not #write()).  If you are using the Net::Telnet
-    #              object to connect to a non-telnet service (such as
-    #              SMTP or POP), this should be set to "false" to prevent
-    #              undesired data corruption.  This value can also be set
-    #              by the #telnetmode() method.
-    #
-    # Timeout:: the number of seconds to wait before timing out both the
-    #           initial attempt to connect to host (in this constructor),
-    #           and all attempts to read data from the host (in #waitfor(),
-    #           #cmd(), and #login()).  Exceeding this timeout causes a
-    #           TimeoutError to be raised.  The default value is 10 seconds.
-    #           You can disable the timeout by setting this value to false.
-    #           In this case, the connect attempt will eventually timeout
-    #           on the underlying connect(2) socket call with an
-    #           Errno::ETIMEDOUT error (but generally only after a few
-    #           minutes), but other attempts to read data from the host
-    #           will hand indefinitely if no data is forthcoming.
-    #
-    # Waittime:: the amount of time to wait after seeing what looks like a 
-    #            prompt (that is, received data that matches the Prompt
-    #            option regular expression) to see if more data arrives.
-    #            If more data does arrive in this time, Net::Telnet assumes
-    #            that what it saw was not really a prompt.  This is to try to 
-    #            avoid false matches, but it can also lead to missing real
-    #            prompts (if, for instance, a background process writes to
-    #            the terminal soon after the prompt is displayed).  By
-    #            default, set to 0, meaning not to wait for more data.
-    #
-    # Proxy:: a proxy object to used instead of opening a direct connection
-    #         to the host.  Must be either another Net::Telnet object or
-    #         an IO object.  If it is another Net::Telnet object, this 
-    #         instance will use that one's socket for communication.  If an
-    #         IO object, it is used directly for communication.  Any other
-    #         kind of object will cause an error to be raised.

-#
-# observer.rb implements the _Observer_ object-oriented design pattern.  The
-# following documentation is copied, with modifications, from "Programming
-# Ruby", by Hunt and Thomas; http://www.rubycentral.com/book/lib_patterns.html.
-#
-# == About
-#
-# The Observer pattern, also known as Publish/Subscribe, provides a simple
-# mechanism for one object to inform a set of interested third-party objects
-# when its state changes. 
-#
-# == Mechanism
-#
-# In the Ruby implementation, the notifying class mixes in the +Observable+
-# module, which provides the methods for managing the associated observer
-# objects.
-#
-# The observers must implement the +update+ method to receive notifications.
-#
-# The observable object must:
-# * assert that it has +changed+
-# * call +notify_observers+
-#
-# == Example
-#
-# The following example demonstrates this nicely.  A +Ticker+, when run,
-# continually receives the stock +Price+ for its +@symbol+.  A +Warner+ is a
-# general observer of the price, and two warners are demonstrated, a +WarnLow+
-# and a +WarnHigh+, which print a warning if the price is below or above their
-# set limits, respectively.
-#
-# The +update+ callback allows the warners to run without being explicitly
-# called.  The system is set up with the +Ticker+ and several observers, and the
-# observers do their duty without the top-level code having to interfere.
-#
-# Note that the contract between publisher and subscriber (observable and
-# observer) is not declared or enforced.  The +Ticker+ publishes a time and a
-# price, and the warners receive that.  But if you don't ensure that your
-# contracts are correct, nothing else can warn you.
-#
-#   require "observer"
-#

-#           lastPrice = price

-#= open-uri.rb
-#
-#open-uri.rb is easy-to-use wrapper for net/http and net/ftp.
-#
-#== Example
-#
-#It is possible to open http/ftp URL as usual a file:
-#
-#  open("http://www.ruby-lang.org/") {|f|
-#    f.each_line {|line| p line}
-#  }
-#
-#The opened file has several methods for meta information as follows since
-#it is extended by OpenURI::Meta.
-#
-#  open("http://www.ruby-lang.org/en") {|f|
-#    f.each_line {|line| p line}
-#    p f.base_uri         # <URI::HTTP:0x40e6ef2 URL:http://www.ruby-lang.org/en/>
-#    p f.content_type     # "text/html"
-#    p f.charset          # "iso-8859-1"
-#    p f.content_encoding # []
-#    p f.last_modified    # Thu Dec 05 02:45:02 UTC 2002
-#  }
-#
-#Additional header fields can be specified by an optional hash argument.
-#
-#  open("http://www.ruby-lang.org/en/",
-#    "User-Agent" => "Ruby/#{RUBY_VERSION}",
-#    "From" => "foo@bar.invalid",
-#    "Referer" => "http://www.ruby-lang.org/") {|f|
-#    ...
-#  }
-#
-#The environment variables such as http_proxy and ftp_proxy are in effect by
-#default.  :proxy => nil disables proxy.
-#
-#  open("http://www.ruby-lang.org/en/raa.html",
-#    :proxy => nil) {|f|
-#    ...
-#  }
-#
-#URI objects can be opened in similar way.
-#
-#  uri = URI.parse("http://www.ruby-lang.org/en/")
-#  uri.open {|f|
-#    ...
-#  }
-#
-#URI objects can be read directly.
-#The returned string is also extended by OpenURI::Meta.
-#
-#  str = uri.read
-#  p str.base_uri

-    #
-    # However, `mode' must be read mode because OpenURI::OpenRead#open doesn't
-    # support write mode (yet).
-    # Also `perm' is just ignored because it is meaningful only for file
-    # creation.
-    #
-    # `options' must be a hash.
-    #
-    # Each pairs which key is a string in the hash specify a extra header
-    # field for HTTP.
-    # I.e. it is ignored for FTP without HTTP proxy.
-    #
-    # The hash may include other option which key is a symbol:
-    #

-    #    If :proxy option is specified, the value should be String, URI,
-    #    boolean or nil.
-    #    When String or URI is given, it is treated as proxy URI.
-    #    When true is given or the option itself is not specified,
-    #    environment variable `scheme_proxy'(or `SCHEME_PROXY') is examined.
-    #    `scheme' is replaced by `http' or `ftp'.
-    #    When false or nil is given, the environment variables are ignored and
-    #    connection will be made to a server directly.

-    #   If :content_length_proc option is specified, the option value procedure
-    #   is called before actual transfer is started.
-    #   It takes one argument which is expected content length in bytes.
-    #
-    #   If two or more transfer is done by HTTP redirection, the procedure
-    #   is called only one for a last transfer.
-    #
-    #   When expected content length is unknown, the procedure is called with
-    #   nil.
-    #   It is happen when HTTP response has no Content-Length header.
-    #
-    # :progress_proc => lambda {|size| ...}
-    #
-    #   If :progress_proc option is specified, the proc is called with one
-    #   argument each time when `open' gets content fragment from network.
-    #   The argument `size' `size' is a accumulated transfered size in bytes.
-    #
-    #   If two or more transfer is done by HTTP redirection, the procedure
-    #   is called only one for a last transfer.
-    #

-# == OptionParser
-#
-# === Introduction
-#
-# OptionParser is a class for command-line option analysis.  It is much more
-# advanced, yet also easier to use, than GetoptLong, and is a more Ruby-oriented
-# solution.
-#
-# === Features
-# 
-# 1. The argument specification and the code to handle it are written in the same
-#    place.
-# 2. It can output an option summary; you don't need to maintain this string
-#    separately.
-# 3. Optional and mandatory arguments are specified very gracefully.
-# 4. Arguments can be automatically converted to a specified class.
-# 5. Arguments can be restricted to a certain set.
-#
-# All of these features are demonstrated in the example below.
-#
-# === Example
-#
-# The following example is a complete Ruby program.  You can run it and see the
-# effect of specifying various options.  This is probably the best way to learn
-# the features of +optparse+.
-#
-#   require 'optparse'
-#   require 'optparse/time'
-#   require 'ostruct'
-#   require 'pp'
-#   
-#   class OptparseExample
-#   
-#     CODES = %w[iso-2022-jp shift_jis euc-jp utf8 binary]
-#     CODE_ALIASES = { "jis" => "iso-2022-jp", "sjis" => "shift_jis" }
-#   
-#     #
-#     # Return a structure describing the options.
-#     #
-#     def self.parse(args)
-#       # The options specified on the command line will be collected in *options*.
-#       # We set default values here.
-#       options = OpenStruct.new
-#       options.library = []
-#       options.inplace = false

-#       options.transfer_type = :auto
-#       options.verbose = false
-#       
-#       opts = OptionParser.new do |opts|
-#         opts.banner = "Usage: example.rb [options]"
-#

-#                 "Require the LIBRARY before executing your script") do |lib|
-#           options.library << lib
-#         end
-#       
-#         # Optional argument; multi-line description.
-#         opts.on("-i", "--inplace [EXTENSION]",
-#                 "Edit ARGV files in place",
-#                 "  (make backup if EXTENSION supplied)") do |ext|
-#           options.inplace = true
-#           options.extension = ext || ''
-#           options.extension.sub!(/\A\.?(?=.)/, ".")  # Ensure extension begins with dot.
-#         end
-#       
-#         # Cast 'delay' argument to a Float.
-#         opts.on("--delay N", Float, "Delay N seconds before executing") do |n|
-#           options.delay = n
-#         end
-#       
-#         # Cast 'time' argument to a Time object.
-#         opts.on("-t", "--time [TIME]", Time, "Begin execution at given time") do |time|
-#           options.time = time
-#         end
-#       
-#         # Cast to octal integer.
-#         opts.on("-F", "--irs [OCTAL]", OptionParser::OctalInteger,
-#                 "Specify record separator (default \\0)") do |rs|
-#           options.record_separator = rs
-#         end
-#       
-#         # List of arguments.
-#         opts.on("--list x,y,z", Array, "Example 'list' of arguments") do |list|
-#           options.list = list
-#         end
-#       
-#         # Keyword completion.  We are specifying a specific set of arguments (CODES
-#         # and CODE_ALIASES - notice the latter is a Hash), and the user may provide
-#         # the shortest unambiguous text.
-#         code_list = (CODE_ALIASES.keys + CODES).join(',')
-#         opts.on("--code CODE", CODES, CODE_ALIASES, "Select encoding",
-#                 "  (#{code_list})") do |encoding|

-#         opts.on("-v", "--[no-]verbose", "Run verbosely") do |v|
-#           options.verbose = v
-#         end

-#       
-#         # No argument, shows at tail.  This will print an options summary.
-#         # Try it and see!

-#       
-#         # Another typical switch to print the version.
-#         opts.on_tail("--version", "Show version") do
-#           puts OptionParser::Version.join('.')

-# = pathname.rb
-#
-# Object-Oriented Pathname Class
-#
-# Author:: Tanaka Akira <akr@m17n.org>
-# Documentation:: Author and Gavin Sinclair
-#
-# For documentation, see class Pathname.
-#
-# <tt>pathname.rb</tt> is distributed with Ruby since 1.8.0.
-#
-
-#
-# == Pathname
-#
-# Pathname represents a pathname which locates a file in a filesystem.
-# It supports only Unix style pathnames.  It does not represent the file
-# itself.  A Pathname can be relative or absolute.  It's not until you try to
-# reference the file that it even matters whether the file exists or not.
-#
-# Pathname is immutable.  It has no method for destructive update.
-#
-# The value of this class is to manipulate file path information in a neater
-# way than standard Ruby provides.  The examples below demonstrate the
-# difference.  *All* functionality from File, FileTest, and some from Dir and
-# FileUtils is included, in an unsurprising way.  It is essentially a facade for
-# all of these, and more.
-#
-# == Examples
-#
-# === Example 1: Using Pathname
-#
-#   require 'pathname'
-#   p = Pathname.new("/usr/bin/ruby")
-#   size = p.size              # 27662
-#   isdir = p.directory?       # false
-#   dir  = p.dirname           # Pathname:/usr/bin
-#   base = p.basename          # Pathname:ruby
-#   dir, base = p.split        # [Pathname:/usr/bin, Pathname:ruby]
-#   data = p.read
-#   p.open { |f| _ } 
-#   p.each_line { |line| _ }
-#
-# === Example 2: Using standard Ruby
-#
-#   p = "/usr/bin/ruby"
-#   size = File.size(p)        # 27662
-#   isdir = File.directory?(p) # false
-#   dir  = File.dirname(p)     # "/usr/bin"
-#   base = File.basename(p)    # "ruby"
-#   dir, base = File.split(p)  # ["/usr/bin", "ruby"]
-#   data = File.read(p)
-#   File.open(p) { |f| _ } 
-#   File.foreach(p) { |line| _ }
-#
-# === Example 3: Special features
-#
-#   p1 = Pathname.new("/usr/lib")   # Pathname:/usr/lib
-#   p2 = p1 + "ruby/1.8"            # Pathname:/usr/lib/ruby/1.8
-#   p3 = p1.parent                  # Pathname:/usr
-#   p4 = p2.relative_path_from(p3)  # Pathname:lib/ruby/1.8
-#   pwd = Pathname.pwd              # Pathname:/home/gavin
-#   pwd.absolute?                   # true
-#   p5 = Pathname.new "."           # Pathname:.
-#   p5 = p5 + "music/../articles"   # Pathname:music/../articles
-#   p5.cleanpath                    # Pathname:articles
-#   p5.realpath                     # Pathname:/home/gavin/articles
-#   p5.children                     # [Pathname:/home/gavin/articles/linux, ...]
-# 
-# == Breakdown of functionality
-#
-# === Core methods
-#
-# These methods are effectively manipulating a String, because that's all a path
-# is.  Except for #mountpoint?, #children, and #realpath, they don't access the
-# filesystem.
-#
-# - +
-# - #join
-# - #parent
-# - #root?
-# - #absolute?
-# - #relative?
-# - #relative_path_from
-# - #each_filename
-# - #cleanpath
-# - #realpath
-# - #children
-# - #mountpoint?
-#
-# === File status predicate methods
-#
-# These methods are a facade for FileTest:
-# - #blockdev?
-# - #chardev?
-# - #directory?
-# - #executable?
-# - #executable_real?
-# - #exist?

-# - #size?
-# - #socket?
-# - #sticky?
-# - #symlink?
-# - #writable?
-# - #writable_real?
-# - #zero?
-#
-# === File property and manipulation methods
-#
-# These methods are a facade for File:
-# - #atime
-# - #ctime

-non-pretty-printed output by (({p})) is:
-  #<PP:0x81fedf0 @genspace=#<Proc:0x81feda0>, @group_queue=#<PrettyPrint::GroupQueue:0x81fed3c @queue=[[#<PrettyPrint::Group:0x81fed78 @breakables=[], @depth=0, @break=false>], []]>, @buffer=[], @newline="\n", @group_stack=[#<PrettyPrint::Group:0x81fed78 @breakables=[], @depth=0, @break=false>], @buffer_width=0, @indent=0, @maxwidth=79, @output_width=2, @output=#<IO:0x8114ee4>>
-
-pretty-printed output by (({pp})) is:
-  #<PP:0x81fedf0
-   @buffer=[],
-   @buffer_width=0,
-   @genspace=#<Proc:0x81feda0>,
-   @group_queue=
-    #<PrettyPrint::GroupQueue:0x81fed3c
-     @queue=
-      [[#<PrettyPrint::Group:0x81fed78 @break=false, @breakables=[], @depth=0>],
-       []]>,
-   @group_stack=
-    [#<PrettyPrint::Group:0x81fed78 @break=false, @breakables=[], @depth=0>],
-   @indent=0,
-   @maxwidth=79,
-   @newline="\n",
-   @output=#<IO:0x8114ee4>,
-   @output_width=2>
-
-I like the latter.  If you do too, this library is for you.
-
-== Usage
-
-: pp(obj)
-    output ((|obj|)) to (({$>})) in pretty printed format.
-
-    It returns (({nil})).
-
-== Output Customization
-To define your customized pretty printing function for your classes,
-redefine a method (({pretty_print(((|pp|)))})) in the class.
-It takes an argument ((|pp|)) which is an instance of the class ((<PP>)).
-The method should use PP#text, PP#breakable, PP#nest, PP#group and
-PP#pp to print the object.
-
-= PP
-== super class
-((<PrettyPrint>))
-
-== class methods
---- PP.pp(obj[, out[, width]])
-    outputs ((|obj|)) to ((|out|)) in pretty printed format of
-    ((|width|)) columns in width.
-
-    If ((|out|)) is omitted, (({$>})) is assumed.
-    If ((|width|)) is omitted, 79 is assumed.
-
-    PP.pp returns ((|out|)).
-
---- PP.singleline_pp(obj[, out])
-    outputs ((|obj|)) to ((|out|)) like (({PP.pp})) but with no indent and
-    newline.
-
-    PP.singleline_pp returns ((|out|)).
-
---- PP.sharing_detection
-    returns the sharing detection flag as a boolean value.
-    It is false by default.
-
---- PP.sharing_detection = boolean_value
-    sets the sharing detection flag.
-
-== methods
---- pp(obj)
-    adds ((|obj|)) to the pretty printing buffer
-    using Object#pretty_print or Object#pretty_print_cycle.
-
-    Object#pretty_print_cycle is used when ((|obj|)) is already
-    printed, a.k.a the object reference chain has a cycle.
-
---- object_group(obj) { ... }
-    is a convenience method which is same as follows:
-
-      group(1, '#<' + obj.class.name, '>') { ... }
-
---- comma_breakable
-    is a convenience method which is same as follows:
-
-      text ','
-      breakable
-
---- seplist(list[, separator_proc[, iter_method]]) {|elt| ... }
-    adds a separated list.
-    The list is separated by comma with breakable space, by default.
-
-    seplist iterates the ((|list|)) using ((|iter_method|)).
-    It yields each object to the block given for seplist.
-    The procedure ((|separator_proc|)) is called between each yields.
-
-    If the iteration is zero times, ((|separator_proc|)) is not called at all.
-
-    If ((|separator_proc|)) is nil or not given,
-    (({lambda { comma_breakable }})) is used.
-    If ((|iter_method|)) is not given, (({:each})) is used.
-
-    For example, following 3 code fragments has similar effect.
-
-      q.seplist([1,2,3]) {|v| xxx v }
-
-      q.seplist([1,2,3], lambda { comma_breakable }, :each) {|v| xxx v }
-
-      xxx 1
-      q.comma_breakable
-      xxx 2
-      q.comma_breakable
-      xxx 3
-
-= Object
---- pretty_print(pp)
-    is a default pretty printing method for general objects.
-    It calls (({pretty_print_instance_variables})) to list instance variables.
-
-    If (({self})) has a customized (redefined) (({inspect})) method,
-    the result of (({self.inspect})) is used but it obviously has no
-    line break hints.
-
-    This module provides predefined pretty_print() methods for some of
-    the most commonly used built-in classes for convenience.
-
---- pretty_print_cycle(pp)
-    is a default pretty printing method for general objects that are
-    detected as part of a cycle.
-
---- pretty_print_instance_variables
-    returns a sorted array of instance variable names.
-
-    This method should return an array of names of instance variables as symbols or strings as:
-    (({[:@a, :@b]})).
-
---- pretty_print_inspect
-    is (({inspect})) implementation using (({pretty_print})).
-    If you implement (({pretty_print})), it can be used as follows.
-
-      alias inspect pretty_print_inspect

-= PrettyPrint
-The class implements pretty printing algorithm.
-It finds line breaks and nice indentations for grouped structure.
-
-By default, the class assumes that primitive elements are strings and
-each byte in the strings have single column in width.
-But it can be used for other situations
-by giving suitable arguments for some methods:
-newline object and space generation block for (({PrettyPrint.new})),
-optional width argument for (({PrettyPrint#text})),
-(({PrettyPrint#breakable})), etc.
-There are several candidates to use them:
-text formatting using proportional fonts,
-multibyte characters which has columns different to number of bytes,
-non-string formatting, etc.
-
-== class methods
---- PrettyPrint.new([output[, maxwidth[, newline]]]) [{|width| ...}]
-    creates a buffer for pretty printing.
-
-    ((|output|)) is an output target.
-    If it is not specified, (({''})) is assumed.
-    It should have a (({<<})) method which accepts
-    the first argument ((|obj|)) of (({PrettyPrint#text})),
-    the first argument ((|sep|)) of (({PrettyPrint#breakable})),
-    the first argument ((|newline|)) of (({PrettyPrint.new})),
-    and
-    the result of a given block for (({PrettyPrint.new})).
-
-    ((|maxwidth|)) specifies maximum line length.
-    If it is not specified, 79 is assumed.
-    However actual outputs may overflow ((|maxwidth|)) if
-    long non-breakable texts are provided.
-
-    ((|newline|)) is used for line breaks.
-    (({"\n"})) is used if it is not specified.
-
-    The block is used to generate spaces.
-    (({{|width| ' ' * width}})) is used if it is not given.
-
---- PrettyPrint.format([output[, maxwidth[, newline[, genspace]]]]) {|q| ...}
-    is a convenience method which is same as follows:
-
-      begin
-        q = PrettyPrint.new(output, maxwidth, newline, &genspace)
-        ...
-        q.flush
-        output
-      end
-
---- PrettyPrint.singleline_format([output[, maxwidth[, newline[, genspace]]]]) {|q| ...}
-    is similar to (({PrettyPrint.format})) but the result has no breaks.
-
-    ((|maxwidth|)), ((|newline|)) and ((|genspace|)) are ignored.
-    The invocation of (({breakable})) in the block doesn't break a line and
-    treated as just an invocation of (({text})).
-
-== methods
---- text(obj[, width])
-    adds ((|obj|)) as a text of ((|width|)) columns in width.
-
-    If ((|width|)) is not specified, (({((|obj|)).length})) is used.
-
---- breakable([sep[, width]])
-    tells "you can break a line here if necessary", and a
-    ((|width|))-column text ((|sep|)) is inserted if a line is not
-    broken at the point.
-
-    If ((|sep|)) is not specified, (({" "})) is used.
-
-    If ((|width|)) is not specified, (({((|sep|)).length})) is used.
-    You will have to specify this when ((|sep|)) is a multibyte
-    character, for example.
-
---- nest(indent) {...}
-    increases left margin after newline with ((|indent|)) for line breaks added
-    in the block.
-
---- group([indent[, open_obj[, close_obj[, open_width[, close_width]]]]]) {...}
-    groups line break hints added in the block.
-    The line break hints are all to be breaked or not.
-
-    If ((|indent|)) is specified, the method call is regarded as nested by
-    (({nest(((|indent|))) { ... }})).
-
-    If ((|open_obj|)) is specified, (({text open_obj, open_width})) is called
-    at first.
-    If ((|close_obj|)) is specified, (({text close_obj, close_width})) is
-    called at last.
-
---- flush
-    outputs buffered data.
-
---- first?
-    first? is obsoleted at 1.8.2.
-
-    first? is a predicate to test the call is a first call to (({first?})) with
-    current group.
-    It is useful to format comma separated values as:
-
-      q.group(1, '[', ']') {
-        xxx.each {|yyy|
-          unless q.first?
-            q.text ','
-            q.breakable
-          end
-          ... pretty printing yyy ...
-        }
-      }
-
-== Bugs
-* Box based formatting?  Other (better) model/algorithm?

-= RDOC - Ruby Documentation System
-
-This package contains Rdoc and SimpleMarkup. Rdoc is an application
-that produces documentation for one or more Ruby source files. We work
-similarly to JavaDoc, parsing the source, and extracting the
-definition for classes, modules, and methods (along with includes and
-requires).  We associate with these optional documentation contained
-in the immediately preceding comment block, and then render the result
-using a pluggable output formatter. (Currently, HTML is the only
-supported format. Markup is a library that converts plain text into
-various output formats. The Markup library is used to interpret the
-comment blocks that Rdoc uses to document methods, classes, and so on.
-
-This library contains two packages, rdoc itself and a text markup
-library, 'markup'. 
-
-== Roadmap
-
-* If you want to use Rdoc to create documentation for your Ruby source
-  files, read on.
-* If you want to include extensions written in C, see rdoc/parsers/parse_c.rb.
-* For information on the various markups available in comment
-  blocks, see markup/simple_markup.rb.
-* If you want to drive Rdoc programatically, see RDoc::RDoc.
-* If you want to use the library to format text blocks into HTML,
-  have a look at SM::SimpleMarkup.
-* If you want to try writing your own HTML output template, see
-  RDoc::Page.
-
-== Summary
-
-Once installed, you can create documentation using the 'rdoc' command
-(the command is 'rdoc.bat' under Windows)
-
-  % rdoc [options]  [names...]
-
-Type "rdoc --help" for an up-to-date option summary.
-
-A typical use might be to generate documentation for a package of Ruby
-source (such as rdoc itself). 
-
-  % rdoc
-
-This command generates documentation for all the Ruby and C source
-files in and below the current directory. These will be stored in a
-documentation tree starting in the subdirectory 'doc'.
-
-You can make this slightly more useful for your readers by having the
-index page contain the documentation for the primary file. In our
-case, we could type
-
-  % rdoc --main rdoc/rdoc.rb
-
-You'll find information on the various formatting tricks you can use
-in comment blocks in the documentation this generates.
-
-RDoc uses file extensions to determine how to process each file. File
-names ending <tt>.rb</tt> and <tt>.rbw</tt> are assumed to be Ruby
-source. Files ending <tt>.c</tt> are parsed as C files. All other
-files are assumed to contain just SimpleMarkup-style markup (with or
-without leading '#' comment markers). If directory names are passed to
-RDoc, they are scanned recursively for C and Ruby source files only.
-
-== Credits
-
-* The Ruby parser in rdoc/parse.rb is based heavily on the outstanding
-  work of Keiju ISHITSUKA of Nippon Rational Inc, who produced the Ruby
-  parser for irb and the rtags package.
-
-* Code to diagram classes and modules was written by Sergey A Yanovitsky
-  (Jah) of Enticla. 
-
-* Charset patch from MoonWolf.
-
-* Rich Kilmer wrote the kilmer.rb output template.
-
-* Dan Brickley led the design of the RDF format.

-
-----
-
-= Usage
-
-RDoc is invoked from the command line using:
-
-   % rdoc <options> [name...]
-
-Files are parsed, and the information they contain collected, before
-any output is produced. This allows cross references between all files
-to be resolved. If a name is a directory, it is traversed. If no
-names are specified, all Ruby files in the current directory (and
-subdirectories) are processed.
-
-Options are:
-
-[<tt>--accessor</tt> <i>name[,name...]</i>]
-    specifies the name(s) of additional methods that should be treated
-    as if they were <tt>attr_</tt><i>xxx</i> methods. Specifying
-    "--accessor db_opt" means lines such as
-
-         db_opt :name, :age
-  
-    will get parsed and displayed in the documentation. Each name may have an
-    optional "=flagtext" appended, in which case the given flagtext will appear
-    where (for example) the 'rw' appears for attr_accessor.
-
-[<tt>--all</tt>]
-    include protected and private methods in the output (by default
-    only public methods are included)
-
-[<tt>--charset</tt> _charset_]
-    Set the character set for the generated HTML.
-
-[<tt>--diagram</tt>]
-    include diagrams showing modules and classes.  This is currently
-    an experimental feature, and may not be supported by all output
-    templates. You need dot V1.8.6 or later to use the --diagram
-    option correctly (http://www.research.att.com/sw/tools/graphviz/).
-
-[<tt>--exclude</tt> <i>pattern</i>]
-    exclude files and directories matching this pattern from processing
-
-[<tt>--extension</tt> <i>new=old</i>]
-    treat files ending <i>.new</i> as if they ended
-    <i>.old</i>. Saying '--extension cgi=rb' causes RDoc to treat .cgi
-    files as Ruby source.
-
-[<tt>fileboxes</tt>]
-    Classes are put in boxes which represents files, where these
-    classes reside. Classes shared between more than one file are
-    shown with list of files that sharing them.  Silently discarded if
-    --diagram is not given Experimental.
-
-[<tt>--fmt</tt> _fmt_]
-    generate output in a particular format.
-
-[<tt>--help</tt>]
-    generate a usage summary.
-
-[<tt>--help-output</tt>]
-    explain the various output options.
-
-[<tt>--image-format</tt> <i>gif/png/jpg/jpeg</i>]
-    sets output image format for diagrams. Can be png, gif, jpeg,
-    jpg. If this option is omitted, png is used. Requires --diagram.
-
-[<tt>--include</tt> <i>dir,...</i>]
-    specify one or more directories to be searched when satisfying
-    :+include+: directives. Multiple <tt>--include</tt> options may be
-    given. The directory containing the file currently being processed
-    is always searched.
-
-[<tt>--inline-source</tt>]
-    By default, the source code of methods is shown in a popup. With
-    this option, it's displayed inline.
-
-[<tt>line-numbers</tt>]
-    include line numbers in the source code
-
-[<tt>--main</tt> _name_]
-    set the class, module, or file to appear on the index page
-
-[<tt>--merge</tt>]
-    when generating _ri_ output, if classes being processed already
-    exist in the destination directory, merge in the current details
-    rather than overwrite them.
-
-[<tt>--one-file</tt>]
-    place all the output into a single file
-
-[<tt>--op</tt> _dir_]
-    set the output directory to _dir_ (the default is the directory
-    "doc")
-
-[<tt>--op-name</tt> _name_]
-    set the name of the output. Has no effect for HTML.
-    "doc")
-
-[<tt>--opname</tt> _name_]
-    set the output name (has no effect for HTML).
-
-[<tt>--promiscuous</tt>]
-    If a module or class is defined in more than one source file, and
-    you click on a particular file's name in the top navigation pane,
-    RDoc will normally only show you the inner classes and modules of
-    that class that are defined in the particular file. Using this
-    option makes it show all classes and modules defined in the class,
-    regardless of the file they were defined in.
-
-[<tt>--quiet</tt>]
-    do not display progress messages
-
-[<tt>--ri</tt>, <tt>--ri-site</tt>, _and_ <tt>--ri-system</tt>]
-    generate output than can be read by the _ri_ command-line tool.
-    By default --ri places its output in ~/.rdoc, --ri-site in
-    $datadir/ri/<ver>/site, and --ri-system in
-    $datadir/ri/<ver>/system. All can be overridden with a subsequent
-    --op option. All default directories are in ri's default search
-    path.
-
-[<tt>--show-hash</tt>]
-    A name of the form #name in a comment is a possible hyperlink to
-    an instance method name. When displayed, the '#' is removed unless
-    this option is specified
-
-[<tt>--style</tt> <i>stylesheet url</i>]
-    specifies the URL of an external stylesheet to use (rather than
-    generating one of our own)
-
-[<tt>tab-width</tt> _n_]
-    set the width of tab characters (default 8)
-
-[<tt>--template</tt> <i>name</i>]
-    specify an alternate template to use when generating output (the
-    default is 'standard'). This template should be in a directory
-    accessible via $: as rdoc/generators/xxxx_template, where 'xxxx'
-    depends on the output formatter.
-
-[<tt>--version</tt>]
-   display  RDoc's version
-
-[<tt>--webcvs</tt> _url_]
-    Specify a URL for linking to a web frontend to CVS. If the URL
-    contains a '\%s', the name of the current file will be
-    substituted; if the URL doesn't contain a '\%s', the filename will
-    be appended to it.
-
-= Example
-
-A typical small Ruby program commented using RDoc might be as follows. You
-can see the formatted result in EXAMPLE.rb and Anagram.
-
-      :include: EXAMPLE.rb
-
-= Markup
-
-Comment blocks can be written fairly naturally, either using '#' on
-successive lines of the comment, or by including the comment in 
-an =begin/=end block. If you use the latter form, the =begin line
-must be flagged with an RDoc tag:
-
-  =begin rdoc
-  Documentation to 
-  be processed by RDoc.
-  =end
-
-Paragraphs are lines that share the left margin. Text indented past
-this margin are formatted verbatim.
-
-1. Lists are typed as indented paragraphs with:
-   * a '*' or '-' (for bullet lists)
-   * a digit followed by a period for 
-     numbered lists
-   * an upper or lower case letter followed
-     by a period for alpha lists.
-
-   For example, the input that produced the above paragraph looked like
-       1. Lists are typed as indented 
-          paragraphs with:
-          * a '*' or '-' (for bullet lists)
-          * a digit followed by a period for 
-            numbered lists
-          * an upper or lower case letter followed
-            by a period for alpha lists.
-
-2. Labeled lists (sometimes called description
-   lists) are typed using square brackets for the label.
-      [cat]   small domestic animal
-      [+cat+] command to copy standard input
-
-3. Labeled lists may also be produced by putting a double colon
-   after the label. This sets the result in tabular form, so the
-   descriptions all line up. This was used to create the 'author'
-   block at the bottom of this description.
-      cat::   small domestic animal
-      +cat+:: command to copy standard input
-
-   For both kinds of labeled lists, if the body text starts on the same
-   line as the label, then the start of that text determines the block
-   indent for the rest of the body. The text may also start on the line
-   following the label, indented from the start of the label. This is
-   often preferable if the label is long. Both the following are
-   valid labeled list entries:
-
-      <tt>--output</tt> <i>name [, name]</i>::
-          specify the name of one or more output files. If multiple
-          files are present, the first is used as the index.
-
-      <tt>--quiet:</tt>:: do not output the names, sizes, byte counts,
-                          index areas, or bit ratios of units as
-                          they are processed.
-
-4. Headings are entered using equals signs
-
-      = Level One Heading
-      == Level Two Heading
-   and so on
-
-5. Rules (horizontal lines) are entered using three or
-   more hyphens.
-
-6. Non-verbatim text can be marked up:
-
-   _italic_::     \_word_ or \<em>text</em>
-   *bold*::       \*word* or \<b>text</b>
-   +typewriter+:: \+word+ or \<tt>text</tt>
-
-   The first form only works around 'words', where a word is a
-   sequence of upper and lower case letters and underscores. Putting a
-   backslash before inline markup stops it being interpreted, which is
-   how I created the table above:
-
-     _italic_::     \_word_ or \<em>text</em>
-     *bold*::       \*word* or \<b>text</b>
-     +typewriter+:: \+word+ or \<tt>text</tt>
-
-7. Names of classes, source files, and any method names
-   containing an underscore or preceded by a hash
-   character are automatically hyperlinked from
-   comment text to their description. 
-
-8. Hyperlinks to the web starting http:, mailto:, ftp:, or www. are
-   recognized. An HTTP url that references an external image file is
-   converted into an inline <IMG..>.  Hyperlinks starting 'link:' are
-   assumed to refer to local files whose path is relative to the --op
-   directory.
-
-   Hyperlinks can also be of the form <tt>label</tt>[url], in which
-   case the label is used in the displayed text, and <tt>url</tt> is
-   used as the target. If <tt>label</tt> contains multiple words,
-   put it in braces: <em>{multi word label}[</em>url<em>]</em>.
-       
-9. Method parameter lists are extracted and displayed with
-   the method description. If a method calls +yield+, then
-   the parameters passed to yield will also be displayed:
-
-      def fred
-        ...
-        yield line, address
-
-   This will get documented as
-
-      fred() { |line, address| ... }
-
-   You can override this using a comment containing 
-   ':yields: ...' immediately after the method definition
-
-      def fred      # :yields: index, position
-        ...
-        yield line, address
-
-   which will get documented as
-
-       fred() { |index, position| ... }
-
-
-10. ':yields:' is an example of a documentation modifier. These appear
-    immediately after the start of the document element they are modifying.
-    Other modifiers include
-
-    [<tt>:nodoc:</tt><i>[all]</i>]
-         don't include this element in the documentation.  For classes
-         and modules, the methods, aliases, constants, and attributes
-         directly within the affected class or module will also be
-         omitted.  By default, though, modules and classes within that
-         class of module _will_ be documented. This is turned off by
-         adding the +all+ modifier.
-
-              module SM  #:nodoc:
-                class Input
-                end
-              end
-              module Markup #:nodoc: all
-                class Output
-                end
-              end
-
-         In the above code, only class <tt>SM::Input</tt> will be
-         documented.
-
-    [<tt>:doc:</tt>]
-         force a method or attribute to be documented even if it
-         wouldn't otherwise be. Useful if, for example, you want to
-         include documentation of a particular private method.
-
-    [<tt>:notnew:</tt>]
-         only applicable to the +initialize+ instance method. Normally
-         RDoc assumes that the documentation and parameters for
-         #initialize are actually for the ::new method, and so fakes
-         out a ::new for the class. THe :notnew: modifier stops
-         this. Remember that #initialize is protected, so you won't
-         see the documentation unless you use the -a command line
-         option.
-
-
-11. RDoc stops processing comments if it finds a comment
-    line containing '<tt>#--</tt>'. This can be used to 
-    separate external from internal comments, or 
-    to stop a comment being associated with a method, 
-    class, or module. Commenting can be turned back on with
-    a line that starts '<tt>#++</tt>'.
-
-        # Extract the age and calculate the
-        # date-of-birth.
-        #--
-        # FIXME: fails if the birthday falls on
-        # February 29th
-        #++
-        # The DOB is returned as a Time object.
-
-        def get_dob(person)
-           ...
-
-12. Comment blocks can contain other directives:
-
-    [<tt>call-seq:</tt>]
-        lines up to the next blank line in the comment are treated as
-        the method's calling sequence, overriding the
-        default parsing of method parameters and yield arguments.
-
-    [<tt>:include:</tt><i>filename</i>] 
-         include the contents of the named file at this point. The
-         file will be searched for in the directories listed by
-         the <tt>--include</tt> option, or in the current
-         directory by default.  The contents of the file will be
-         shifted to have the same indentation as the ':' at the
-         start of the :include: directive.
-
-    [<tt>:title:</tt><i>text</i>]
-         Sets the title for the document. Equivalent to the --title command
-         line parameter. (The command line parameter overrides any :title:
-         directive in the source).
-
-    [<tt>:enddoc:</tt>]
-         Document nothing further at the current level.
-
-    [<tt>:main:</tt><i>name</i>]
-         Equivalent to the --main command line parameter.
-
-    [<tt>:stopdoc: / :startdoc:</tt>]
-         Stop and start adding new documentation elements to the
-         current container. For example, if a class has a number of
-         constants that you don't want to document, put a
-         <tt>:stopdoc:</tt> before the first, and a
-         <tt>:startdoc:</tt> after the last. If you don't specifiy a
-         <tt>:startdoc:</tt> by the end of the container, disables
-         documentation for the entire class or module.

-# = CSS2 RDoc HTML template
-#
-# This is a template for RDoc that uses XHTML 1.0 Transitional and dictates a
-# bit more of the appearance of the output to cascading stylesheets than the
-# default. It was designed for clean inline code display, and uses DHTMl to
-# toggle the visbility of each method's source with each click on the '[source]'
-# link.

-module RDoc
-
-# This is how you define the HTML that RDoc generates. Simply create
-# a file in rdoc/generators/html_templates that creates the
-# module RDoc::Page and populate it as described below. Then invoke
-# rdoc using the --template <name of your file> option, and
-# your template will be used.
-#
-# The constants defining pages use a simple templating system:
-#
-# * The templating system is passed a hash. Keys in the hash correspond
-#   to tags on this page. The tag %abc% is looked up in the hash,
-#   and is replaced by the corresponding hash value.
-#
-# * Some tags are optional. You can detect this using IF/ENDIF
-#
-#      IF: title
-#      The value of title is %title%
-#      ENDIF: title
-#
-# * Some entries in the hash have values that are arrays, where each
-#   entry in the array is itself a hash. These are used to generate
-#   lists using the START: construct. For example, given a hash
-#   containing
-# 
-#      { 'people' => [ { 'name' => 'Fred', 'age' => '12' },
-#                      { 'name' => 'Mary', 'age' => '21' } ]
-#
-#   You could generate a simple table using
-#
-#      <table>
-#      START:people
-#        <tr><td>%name%<td>%age%</tr>
-#      END:people
-#      </table>
-#
-#   These lists can be nested to an arbitrary depth
-#
-# * the construct HREF:url:name: generates <a href="%url%">%name%</a>
-#   if +url+ is defined in the hash, or %name% otherwise.
-#
-#
-# Your file must contain the following constants
-#
-# [*FONTS*]  a list of fonts to be used
-# [*STYLE*]  a CSS section (without the <style> or comments). This is
-#            used to generate a style.css file
-#
-# [*BODY*] 
-#   The main body of all non-index RDoc pages. BODY will contain
-#   two !INCLUDE!s. The first is used to include a document-type
-#   specific header (FILE_PAGE or CLASS_PAGE). The second include
-#   is for the method list (METHOD_LIST). THe body is passed:
-#
-#   %title%::
-#       the page's title
-#

-#       required by this file.
-#
-#   %methods%::
-#       an optional list of %aref%/%name%, one for each method
-#       documented on this page. This is intended to be an index.
-#
-#   %attributes%::  
-#       An optional list. For each attribute it contains:
-#       %name%::   the attribute name
-#       %rw%::     r/o, w/o, or r/w
-#       %a_desc%:: description of the attribute
-#
-#   %classlist%:: 
-#       An optional string containing an already-formatted list of
-#       classes and modules documented in this file
-#
-#   For FILE_PAGE entries, the body will be passed
-#
-#   %short_name%::  
-#       The name of the file
-#
-#   %full_path%::
-#       The full path to the file
-#
-#   %dtm_modified%::
-#       The date/time the file was last changed
-#
-#   For class and module pages, the body will be passed
-#
-#   %classmod%::
-#       The name of the class or module
-#
-#   %files%::
-#       A list. For each file this class is defined in, it contains:
-#       %full_path_url%:: an (optional) URL of the RDoc page
-#                         for this file
-#       %full_path%::     the name of the file
-#
-#   %par_url%::
-#       The (optional) URL of the RDoc page documenting this class's
-#       parent class
-#
-#   %parent%::
-#       The name of this class's parent.
-#
-#   For both files and classes, the body is passed the following information
-#   on includes and methods:
-#
-#   %includes%::    
-#       Optional list of included modules. For each, it receives
-#       %aref%:: optional URL to RDoc page for the module
-#       %name%:: the name of the module
-#
-#   %method_list%::
-#       Optional list of methods of a particular class and category.
-#
-#   Each method list entry contains:
-#
-#   %type%::        public/private/protected
-#   %category%::    instance/class
-#   %methods%::     a list of method descriptions
-#
-#   Each method description contains:
-#
-#   %aref%::        a target aref, used when referencing this method
-#                   description. You should code this as <a name="%aref%">

-# [*FILE_PAGE*]
-#         Header for pages documenting files. See
-#         BODY above for the available parameters.
-#
-# [*METHOD_LIST*]
-#         Controls the display of the listing of methods. See BODY for
-#         parameters.
-#
-# [*INDEX*]
-#         The top-level index page. For a browser-like environment
-#         define a frame set that includes the file, class, and

-# = Introduction
-#
-# SimpleMarkup parses plain text documents and attempts to decompose
-# them into their constituent parts. Some of these parts are high-level:
-# paragraphs, chunks of verbatim text, list entries and the like. Other
-# parts happen at the character level: a piece of bold text, a word in
-# code font. This markup is similar in spirit to that used on WikiWiki
-# webs, where folks create web pages using a simple set of formatting
-# rules.
-#
-# SimpleMarkup itself does no output formatting: this is left to a
-# different set of classes.
-#
-# SimpleMarkup is extendable at runtime: you can add new markup
-# elements to be recognised in the documents that SimpleMarkup parses.
-#
-# SimpleMarkup is intended to be the basis for a family of tools which
-# share the common requirement that simple, plain-text should be
-# rendered in a variety of different output formats and media. It is
-# envisaged that SimpleMarkup could be the basis for formating RDoc
-# style comment blocks, Wiki entries, and online FAQs.
-#
-# = Basic Formatting
-#
-# * SimpleMarkup looks for a document's natural left margin. This is
-#   used as the initial margin for the document.
-#
-# * Consecutive lines starting at this margin are considered to be a
-#   paragraph.
-#
-# * If a paragraph starts with a "*", "-", or with "<digit>.", then it is
-#   taken to be the start of a list. The margin in increased to be the
-#   first non-space following the list start flag. Subsequent lines
-#   should be indented to this new margin until the list ends. For
-#   example:
-#
-#      * this is a list with three paragraphs in
-#        the first item. This is the first paragraph.
-#
-#        And this is the second paragraph.
-#
-#        1. This is an indented, numbered list.
-#        2. This is the second item in that list
-#
-#        This is the third conventional paragraph in the
-#        first list item.
-#
-#      * This is the second item in the original list
-#
-# * You can also construct labeled lists, sometimes called description
-#   or definition lists. Do this by putting the label in square brackets
-#   and indenting the list body:
-#
-#       [cat]  a small furry mammal
-#              that seems to sleep a lot
-#
-#       [ant]  a little insect that is known
-#              to enjoy picnics
-#
-#   A minor variation on labeled lists uses two colons to separate the
-#   label from the list body:
-#
-#       cat::  a small furry mammal
-#              that seems to sleep a lot
-#
-#       ant::  a little insect that is known
-#              to enjoy picnics
-#     
-#   This latter style guarantees that the list bodies' left margins are
-#   aligned: think of them as a two column table.
-#
-# * Any line that starts to the right of the current margin is treated
-#   as verbatim text. This is useful for code listings. The example of a
-#   list above is also verbatim text.
-#
-# * A line starting with an equals sign (=) is treated as a
-#   heading. Level one headings have one equals sign, level two headings
-#   have two,and so on.
-#
-# * A line starting with three or more hyphens (at the current indent)
-#   generates a horizontal rule. THe more hyphens, the thicker the rule
-#   (within reason, and if supported by the output device)
-#
-# * You can use markup within text (except verbatim) to change the
-#   appearance of parts of that text. Out of the box, SimpleMarkup
-#   supports word-based and general markup.
-#
-#   Word-based markup uses flag characters around individual words:
-#
-#   [\*word*]  displays word in a *bold* font
-#   [\_word_]  displays word in an _emphasized_ font
-#   [\+word+]  displays word in a +code+ font
-#
-#   General markup affects text between a start delimiter and and end
-#   delimiter. Not surprisingly, these delimiters look like HTML markup.
-#
-#   [\<b>text...</b>]    displays word in a *bold* font
-#   [\<em>text...</em>]  displays word in an _emphasized_ font
-#   [\<i>text...</i>]    displays word in an _emphasized_ font
-#   [\<tt>text...</tt>]  displays word in a +code+ font
-#
-#   Unlike conventional Wiki markup, general markup can cross line
-#   boundaries. You can turn off the interpretation of markup by
-#   preceding the first character with a backslash, so \\\<b>bold
-#   text</b> and \\\*bold* produce \<b>bold text</b> and \*bold
-#   respectively.
-#

-  # == Synopsis
-  #
-  # This code converts <tt>input_string</tt>, which is in the format
-  # described in markup/simple_markup.rb, to HTML. The conversion
-  # takes place in the +convert+ method, so you can use the same
-  # SimpleMarkup object to convert multiple input strings.
-  #
-  #   require 'rdoc/markup/simple_markup'
-  #   require 'rdoc/markup/simple_markup/to_html'

-  #   p = SM::SimpleMarkup.new
-  #   h = SM::ToHtml.new
-  #
-  #   puts p.convert(input_string, h)
-  #
-  # You can extend the SimpleMarkup parser to recognise new markup
-  # sequences, and to add special processing for text that matches a
-  # regular epxression. Here we make WikiWords significant to the parser,
-  # and also make the sequences {word} and \<no>text...</no> signify
-  # strike-through text. When then subclass the HTML output class to deal
-  # with these:
-  #
-  #   require 'rdoc/markup/simple_markup'
-  #   require 'rdoc/markup/simple_markup/to_html'
-  #
-  #   class WikiHtml < SM::ToHtml
-  #     def handle_special_WIKIWORD(special)
-  #       "<font color=red>" + special.text + "</font>"
-  #     end
-  #   end
-  #
-  #   p = SM::SimpleMarkup.new
-  #   p.add_word_pair("{", "}", :STRIKE)
-  #   p.add_html("no", :STRIKE)
-  #
-  #   p.add_special(/\b([A-Z][a-z]+[A-Z]\w+)/, :WIKIWORD)

-      How RDoc generates output depends on the output formatter being
-      used, and on the options you give.
-
-      - HTML output is normally produced into a number of separate files
-        (one per class, module, and file, along with various indices). 
-        These files will appear in the directory given by the --op
-        option (doc/ by default).
-
-      - XML output by default is written to standard output. If a
-        --opname option is given, the output will instead be written
-        to a file with that name in the output directory.
-
-      - .chm files (Windows help files) are written in the --op directory.
-        If an --opname parameter is present, that name is used, otherwise
-        the file will be called rdoc.chm.
-
-      For information on other RDoc options, use "rdoc --help".

-  # We attempt to parse C extension files. Basically we look for
-  # the standard patterns that you find in extensions: <tt>rb_define_class,
-  # rb_define_method</tt> and so on. We also try to find the corresponding
-  # C source for the methods and extract comments, but if we fail
-  # we don't worry too much.
-  #
-  # The comments associated with a Ruby method are extracted from the C
-  # comment block associated with the routine that _implements_ that
-  # method, that is to say the method whose name is given in the
-  # <tt>rb_define_method</tt> call. For example, you might write:
-  #
-  #  /*
-  #   * Returns a new array that is a one-dimensional flattening of this
-  #   * array (recursively). That is, for every element that is an array,
-  #   * extract its elements into the new array.
-  #   *
-  #   *    s = [ 1, 2, 3 ]           #=> [1, 2, 3]
-  #   *    t = [ 4, 5, 6, [7, 8] ]   #=> [4, 5, 6, [7, 8]]
-  #   *    a = [ s, t, 9, 10 ]       #=> [[1, 2, 3], [4, 5, 6, [7, 8]], 9, 10]
-  #   *    a.flatten                 #=> [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

-  #
-  # Here RDoc will determine from the rb_define_method line that there's a
-  # method called "flatten" in class Array, and will look for the implementation
-  # in the method rb_ary_flatten. It will then use the comment from that
-  # method in the HTML output. This method must be in the same source file
-  # as the rb_define_method.
-  #
-  # C classes can be diagramed (see /tc/dl/ruby/ruby/error.c), and RDoc
-  # integrates C and Ruby source into one tree
-  #
-  # The comment blocks may include special direcives:
-  #
-  # [Document-class: <i>name</i>]
-  #   This comment block is documentation for the given class. Use this
-  #   when the <tt>Init_xxx</tt> method is not named after the class.
-  #
-  # [Document-method: <i>name</i>]
-  #   This comment documents the named method. Use when RDoc cannot outomatically
-  #   find the method from it's declaration
-  #
-  # [call-seq:  <i>text up to an empty line</i>]
-  #   Because C source doesn't give descripive names to Ruby-level parameters,
-  #   you need to document the calling sequence explicitly
-  #
-  # In additon, RDoc assumes by default that the C method implementing a 
-  # Ruby function is in the same source file as the rb_define_method call.
-  # If this isn't the case, add the comment 
-  #
-  #    rb_define_method(....);  // in: filename
-  #
-  # As an example, we might have an extension that defines multiple classes
-  # in its Init_xxx method. We could document them using
-  #
-  #  
-  #  /*
-  #   * Document-class:  MyClass
-  #   *
-  #   * Encapsulate the writing and reading of the configuration
-  #   * file. ...
-  #   */
-  #  
-  #  /*
-  #   * Document-method: read_value
-  #   *
-  #   * call-seq:
-  #   *   cfg.read_value(key)            -> value
-  #   *   cfg.read_value(key} { |key| }  -> value
-  #   *
-  #   * Return the value corresponding to +key+ from the configuration.

-  ######################################################################
-  #
-  # Read an input stream character by character. We allow for unlimited
-  # ungetting of characters just read.
-  #
-  # We simplify the implementation greatly by reading the entire input
-  # into a buffer initially, and then simply traversing it using
-  # pointers.
-  #
-  # We also have to allow for the <i>here document diversion</i>. This
-  # little gem comes about when the lexer encounters a here
-  # document. At this point we effectively need to split the input
-  # stream into two parts: one to read the body of the here document,
-  # the other to read the rest of the input line where the here
-  # document was initially encountered. For example, we might have
-  #
-  #   do_something(<<-A, <<-B)
-  #     stuff
-  #     for
-  #   A
-  #     stuff
-  #     for
-  #   B
-  #
-  # When the lexer encounters the <<A, it reads until the end of the
-  # line, and keeps it around for later. It then reads the body of the
-  # here document.  Once complete, it needs to read the rest of the
-  # original line, but then skip the here document body.

-= resolv library
-resolv.rb is a resolver library written in Ruby.
-Since it is written in Ruby, it is thread-aware.
-I.e. it can resolv many hostnames concurrently.
-
-It is possible to lookup various resources of DNS using DNS module directly.
-
-== example
-  Resolv.getaddress("www.ruby-lang.org")
-  Resolv.getname("210.251.121.214")
-
-  Resolv::DNS.open {|dns|
-    dns.getresources("www.ruby-lang.org", Resolv::DNS::Resource::IN::A).collect {|r| r.address}
-    dns.getresources("ruby-lang.org", Resolv::DNS::Resource::IN::MX).collect {|r| [r.exchange.to_s, r.preference]}
-  }
-
-== Resolv class
-
-=== class methods
---- Resolv.getaddress(name)
---- Resolv.getaddresses(name)
---- Resolv.each_address(name) {|address| ...}
-    They lookups IP addresses of ((|name|)) which represents a hostname
-    as a string by default resolver.
-
-    getaddress returns first entry of lookupped addresses.

-=scanf for Ruby
-
-==Description
-
-scanf for Ruby is an implementation of the C function scanf(3),
-modified as necessary for Ruby compatibility.
-
-The methods provided are String#scanf, IO#scanf, and
-Kernel#scanf. Kernel#scanf is a wrapper around STDIN.scanf.  IO#scanf
-can be used on any IO stream, including file handles and sockets.
-scanf can be called either with or without a block.
-
-scanf for Ruby scans an input string or stream according to a
-<b>format</b>, as described below ("Conversions"), and returns an
-array of matches between the format and the input.  The format is
-defined in a string, and is similar (though not identical) to the
-formats used in Kernel#printf and Kernel#sprintf.
-
-The format may contain <b>conversion specifiers</b>, which tell scanf
-what form (type) each particular matched substring should be converted
-to (e.g., decimal integer, floating point number, literal string,
-etc.)  The matches and conversions take place from left to right, and
-the conversions themselves are returned as an array.
-
-The format string may also contain characters other than those in the
-conversion specifiers.  White space (blanks, tabs, or newlines) in the
-format string matches any amount of white space, including none, in
-the input.  Everything else matches only itself.
-
-Scanning stops, and scanf returns, when any input character fails to
-match the specifications in the format string, or when input is
-exhausted, or when everything in the format string has been
-matched. All matches found up to the stopping point are returned in
-the return array (or yielded to the block, if a block was given).
-
-
-==Basic usage
-
-   require 'scanf.rb'
-
-   # String#scanf and IO#scanf take a single argument (a format string)
-   array = aString.scanf("%d%s")
-   array = anIO.scanf("%d%s")
-
-   # Kernel#scanf reads from STDIN
-   array = scanf("%d%s")
-
-==Block usage
-
-When called with a block, scanf keeps scanning the input, cycling back
-to the beginning of the format string, and yields a new array of
-conversions to the block every time the format string is matched
-(including partial matches, but not including complete failures).  The
-actual return value of scanf when called with a block is an array
-containing the results of all the executions of the block. 
-
-   str = "123 abc 456 def 789 ghi"
-   str.scanf("%d%s") { |num,str| [ num * 2, str.upcase ] }
-     # => [[246, "ABC"], [912, "DEF"], [1578, "GHI"]]
-
-==Conversions
-
-The single argument to scanf is a format string, which generally
-includes one or more conversion specifiers. Conversion specifiers
-begin with the percent character ('%') and include information about
-what scanf should next scan for (string, decimal number, single
-character, etc.).
-
-There may be an optional maximum field width, expressed as a decimal
-integer, between the % and the conversion. If no width is given, a
-default of `infinity' is used (with the exception of the %c specifier;
-see below).  Otherwise, given a field width of <em>n</em> for a given
-conversion, at most <em>n</em> characters are scanned in processing
-that conversion.  Before conversion begins, most conversions skip
-white space in the input string; this white space is not counted
-against the field width.
-
-The following conversions are available. (See the files EXAMPLES
-and <tt>tests/scanftests.rb</tt> for examples.)
-
-[%]
-  Matches a literal `%'. That is, `%%' in the format string matches a
-  single input `%' character. No conversion is done, and the resulting
-  '%' is not included in the return array.
-
-[d]
-  Matches an optionally signed decimal integer.
-
-[u]
-  Same as d.
-
-[i] 
-  Matches an optionally signed integer. The integer is read in base
-  16 if it begins with `0x' or `0X', in base 8 if it begins with `0',
-  and in base 10 other- wise. Only characters that correspond to the
-  base are recognized.
-
-[o]
-  Matches an optionally signed octal integer.
-
-[x,X]
-  Matches an optionally signed hexadecimal integer,
-
-[f,g,e,E]
-  Matches an optionally signed floating-point number.
-
-[s]
-  Matches a sequence of non-white-space character. The input string stops at
-  white space or at the maximum field width, whichever occurs first.
-
-[c]
-  Matches a single character, or a sequence of <em>n</em> characters if a
-  field width of <em>n</em> is specified. The usual skip of leading white
-  space is suppressed. To skip white space first, use an explicit space in
-  the format.
-
-[<tt>[</tt>]
-  Matches a nonempty sequence of characters from the specified set
-  of accepted characters.  The usual skip of leading white space is
-  suppressed.  This bracketed sub-expression is interpreted exactly like a
-  character class in a Ruby regular expression.  (In fact, it is placed as-is
-  in a regular expression.)  The matching against the input string ends with
-  the appearance of a character not in (or, with a circumflex, in) the set,
-  or when the field width runs out, whichever comes first.
-
-===Assignment suppression
-
-To require that a particular match occur, but without including the result
-in the return array, place the <b>assignment suppression flag</b>, which is
-the star character ('*'), immediately after the leading '%' of a format
-specifier (just before the field width, if any).
-
-==Examples
-
-See the files <tt>EXAMPLES</tt> and <tt>tests/scanftests.rb</tt>.
-
-==scanf for Ruby compared with scanf in C
-
-scanf for Ruby is based on the C function scanf(3), but with modifications,
-dictated mainly by the underlying differences between the languages.
-
-===Unimplemented flags and specifiers
-
-* The only flag implemented in scanf for Ruby is '<tt>*</tt>' (ignore
-  upcoming conversion). Many of the flags available in C versions of scanf(4)
-  have to do with the type of upcoming pointer arguments, and are literally
-  meaningless in Ruby.
-
-* The <tt>n</tt> specifier (store number of characters consumed so far in
-  next pointer) is not implemented.
-
-* The <tt>p</tt> specifier (match a pointer value) is not implemented.
-
-===Altered specifiers
-
-[o,u,x,X]
-  In scanf for Ruby, all of these specifiers scan for an optionally signed
-  integer, rather than for an unsigned integer like their C counterparts.
-
-===Return values
-
-scanf for Ruby returns an array of successful conversions, whereas
-scanf(3) returns the number of conversions successfully
-completed. (See below for more details on scanf for Ruby's return
-values.)
-
-==Return values
-
-Without a block, scanf returns an array containing all the conversions
-it has found. If none are found, scanf will return an empty array. An
-unsuccesful match is never ignored, but rather always signals the end
-of the scanning operation. If the first unsuccessful match takes place
-after one or more successful matches have already taken place, the
-returned array will contain the results of those successful matches.
-
-With a block scanf returns a 'map'-like array of transformations from
-the block -- that is, an array reflecting what the block did with each
-yielded result from the iterative scanf operation.  (See "Block
-usage", above.)
-
-==Test suite
-
-scanf for Ruby includes a suite of unit tests (requiring the
-<tt>TestUnit</tt> package), which can be run with the command <tt>ruby
-tests/scanftests.rb</tt> or the command <tt>make test</tt>.
-
-==Current limitations and bugs
-
-When using IO#scanf under Windows, make sure you open your files in
-binary mode:
-
-    File.open("filename", "rb")
-
-so that scanf can keep track of characters correctly.
-
-Support for character classes is reasonably complete (since it
-essentially piggy-backs on Ruby's regular expression handling of
-character classes), but users are advised that character class testing
-has not been exhaustive, and that they should exercise some caution
-in using any of the more complex and/or arcane character class
-idioms.
-
-
-==Technical notes
-
-===Rationale behind scanf for Ruby
-
-The impetus for a scanf implementation in Ruby comes chiefly from the fact
-that existing pattern matching operations, such as Regexp#match and
-String#scan, return all results as strings, which have to be converted to
-integers or floats explicitly in cases where what's ultimately wanted are
-integer or float values.
-
-===Design of scanf for Ruby
-
-scanf for Ruby is essentially a <format string>-to-<regular
-expression> converter.
-
-When scanf is called, a FormatString object is generated from the
-format string ("%d%s...") argument. The FormatString object breaks the
-format string down into atoms ("%d", "%5f", "blah", etc.), and from
-each atom it creates a FormatSpecifier object, which it
-saves.
-
-Each FormatSpecifier has a regular expression fragment and a "handler"
-associated with it. For example, the regular expression fragment
-associated with the format "%d" is "([-+]?\d+)", and the handler
-associated with it is a wrapper around String#to_i. scanf itself calls
-FormatString#match, passing in the input string. FormatString#match
-iterates through its FormatSpecifiers; for each one, it matches the
-corresponding regular expression fragment against the string. If
-there's a match, it sends the matched string to the handler associated
-with the FormatSpecifier.
-
-Thus, to follow up the "%d" example: if "123" occurs in the input
-string when a FormatSpecifier consisting of "%d" is reached, the "123"
-will be matched against "([-+]?\d+)", and the matched string will be
-rendered into an integer by a call to to_i.
-
-The rendered match is then saved to an accumulator array, and the
-input string is reduced to the post-match substring. Thus the string
-is "eaten" from the left as the FormatSpecifiers are applied in
-sequence.  (This is done to a duplicate string; the original string is
-not altered.)
-
-As soon as a regular expression fragment fails to match the string, or
-when the FormatString object runs out of FormatSpecifiers, scanning
-stops and results accumulated so far are returned in an array.

-# == Overview 
-# 
-# This library provides the Set class, which deals with a collection
-# of unordered values with no duplicates.  It is a hybrid of Array's
-# intuitive inter-operation facilities and Hash's fast lookup.  If you
-# need to keep values ordered, use the SortedSet class.
-#
-# The method +to_set+ is added to Enumerable for convenience.
-#
-# See the Set class for an example of usage.
-
-
-#
-# Set implements a collection of unordered values with no duplicates.
-# This is a hybrid of Array's intuitive inter-operation facilities and
-# Hash's fast lookup.
-#
-# Several methods accept any Enumerable object (implementing +each+)
-# for greater flexibility: new, replace, merge, subtract, |, &, -, ^.
-#
-# The equality of each couple of elements is determined according to
-# Object#eql? and Object#hash, since Set uses Hash as storage.
-#
-# Finally, if you are using class Set, you can also use Enumerable#to_set
-# for convenience.
-#
-# == Example
-#
-#   require 'set'
-#   s1 = Set.new [1, 2]                   # -> #<Set: {1, 2}>
-#   s2 = [1, 2].to_set                    # -> #<Set: {1, 2}>
-#   s1 == s2                              # -> true
-#   s1.add("foo")                         # -> #<Set: {1, 2, "foo"}>
-#   s1.merge([2, 6])                      # -> #<Set: {6, 1, 2, "foo"}>
-#   s1.subset? s2                         # -> false
-#   s2.subset? s1                         # -> true

-# The Singleton module implements the Singleton pattern.
-#
-# Usage:
-#    class Klass
-#       include Singleton
-#       # ...
-#    end
-#
-# *  this ensures that only one instance of Klass lets call it
-#    ``the instance'' can be created.
-#
-#    a,b  = Klass.instance, Klass.instance
-#    a == b   # => true
-#    a.new    #  NoMethodError - new is private ...
-#
-# *  ``The instance'' is created at instantiation time, in other
-#    words the first call of Klass.instance(), thus
-#
-#    class OtherKlass
-#        include Singleton
-#        # ...
-#    end
-#    ObjectSpace.each_object(OtherKlass){} # => 0.
-#
-# *  This behavior is preserved under inheritance and cloning.
-#
-#
-#
-# This is achieved by marking
-# *  Klass.new and Klass.allocate - as private
-#
-# Providing (or modifying) the class methods
-# *  Klass.inherited(sub_klass) and Klass.clone()  - 
-#    to ensure that the Singleton pattern is properly
-#    inherited and cloned.
-#
-# *  Klass.instance()  -  returning ``the instance''. After a
-#    successful self modifying (normally the first) call the
-#    method body is a simple:
-#
-#       def Klass.instance()
-#         return @__instance__
-#       end
-#
-# *  Klass._load(str)  -  calling Klass.instance()
-#
-# *  Klass._instantiate?()  -  returning ``the instance'' or
-#    nil. This hook method puts a second (or nth) thread calling
-#    Klass.instance() on a waiting loop. The return value
-#    signifies the successful completion or premature termination
-#    of the first, or more generally, current "instantiation thread".
-#
-#
-# The instance method of Singleton are
-# * clone and dup - raising TypeErrors to prevent cloning or duping
-#
-# *  _dump(depth) - returning the empty string.  Marshalling strips
-#    by default all state information, e.g. instance variables and
-#    taint state, from ``the instance''.  Providing custom _load(str)
-#    and _dump(depth) hooks allows the (partially) resurrections of
-#    a previous state of ``the instance''.

-  # = Test::Unit - Ruby Unit Testing Framework
-  # 
-  # == Introduction
-  # 
-  # Unit testing is making waves all over the place, largely due to the
-  # fact that it is a core practice of XP. While XP is great, unit testing
-  # has been around for a long time and has always been a good idea. One
-  # of the keys to good unit testing, though, is not just writing tests,
-  # but having tests. What's the difference? Well, if you just _write_ a
-  # test and throw it away, you have no guarantee that something won't
-  # change later which breaks your code. If, on the other hand, you _have_
-  # tests (obviously you have to write them first), and run them as often
-  # as possible, you slowly build up a wall of things that cannot break
-  # without you immediately knowing about it. This is when unit testing
-  # hits its peak usefulness.
-  # 
-  # Enter Test::Unit, a framework for unit testing in Ruby, helping you to
-  # design, debug and evaluate your code by making it easy to write and
-  # have tests for it.
-  # 
-  # 
-  # == Notes
-  # 
-  # Test::Unit has grown out of and superceded Lapidary.
-  # 
-  # 
-  # == Feedback
-  # 
-  # I like (and do my best to practice) XP, so I value early releases,
-  # user feedback, and clean, simple, expressive code. There is always
-  # room for improvement in everything I do, and Test::Unit is no
-  # exception. Please, let me know what you think of Test::Unit as it
-  # stands, and what you'd like to see expanded/changed/improved/etc. If
-  # you find a bug, let me know ASAP; one good way to let me know what the
-  # bug is is to submit a new test that catches it :-) Also, I'd love to
-  # hear about any successes you have with Test::Unit, and any
-  # documentation you might add will be greatly appreciated. My contact
-  # info is below.
-  # 
-  # 
-  # == Contact Information
-  # 
-  # A lot of discussion happens about Ruby in general on the ruby-talk
-  # mailing list (http://www.ruby-lang.org/en/ml.html), and you can ask
-  # any questions you might have there. I monitor the list, as do many
-  # other helpful Rubyists, and you're sure to get a quick answer. Of
-  # course, you're also welcome to email me (Nathaniel Talbott) directly
-  # at mailto:testunit@talbott.ws, and I'll do my best to help you out.
-  # 
-  # 
-  # == Credits
-  # 
-  # I'd like to thank...
-  # 
-  # Matz, for a great language!
-  # 
-  # Masaki Suketa, for his work on RubyUnit, which filled a vital need in
-  # the Ruby world for a very long time. I'm also grateful for his help in
-  # polishing Test::Unit and getting the RubyUnit compatibility layer
-  # right. His graciousness in allowing Test::Unit to supercede RubyUnit
-  # continues to be a challenge to me to be more willing to defer my own
-  # rights.
-  # 
-  # Ken McKinlay, for his interest and work on unit testing, and for his
-  # willingness to dialog about it. He was also a great help in pointing
-  # out some of the holes in the RubyUnit compatibility layer.
-  # 
-  # Dave Thomas, for the original idea that led to the extremely simple
-  # "require 'test/unit'", plus his code to improve it even more by
-  # allowing the selection of tests from the command-line. Also, without
-  # RDoc, the documentation for Test::Unit would stink a lot more than it
-  # does now.
-  # 
-  # Everyone who's helped out with bug reports, feature ideas,
-  # encouragement to continue, etc. It's a real privilege to be a part of
-  # the Ruby community.
-  # 
-  # The guys at RoleModel Software, for putting up with me repeating, "But
-  # this would be so much easier in Ruby!" whenever we're coding in Java.
-  # 
-  # My Creator, for giving me life, and giving it more abundantly.

-  # ----
-  #
-  # = Usage
-  #
-  # The general idea behind unit testing is that you write a _test_
-  # _method_ that makes certain _assertions_ about your code, working
-  # against a _test_ _fixture_. A bunch of these _test_ _methods_ are
-  # bundled up into a _test_ _suite_ and can be run any time the
-  # developer wants. The results of a run are gathered in a _test_
-  # _result_ and displayed to the user through some UI. So, lets break
-  # this down and see how Test::Unit provides each of these necessary
-  # pieces.
-  #
-  #
-  # == Assertions
-  #
-  # These are the heart of the framework. Think of an assertion as a
-  # statement of expected outcome, i.e. "I assert that x should be equal
-  # to y". If, when the assertion is executed, it turns out to be
-  # correct, nothing happens, and life is good. If, on the other hand,
-  # your assertion turns out to be false, an error is propagated with
-  # pertinent information so that you can go back and make your
-  # assertion succeed, and, once again, life is good. For an explanation
-  # of the current assertions, see Test::Unit::Assertions.
-  #
-  #
-  # == Test Method & Test Fixture
-  #
-  # Obviously, these assertions have to be called within a context that
-  # knows about them and can do something meaningful with their
-  # pass/fail value. Also, it's handy to collect a bunch of related
-  # tests, each test represented by a method, into a common test class
-  # that knows how to run them. The tests will be in a separate class
-  # from the code they're testing for a couple of reasons. First of all,
-  # it allows your code to stay uncluttered with test code, making it
-  # easier to maintain. Second, it allows the tests to be stripped out
-  # for deployment, since they're really there for you, the developer,
-  # and your users don't need them. Third, and most importantly, it
-  # allows you to set up a common test fixture for your tests to run
-  # against.
-  #
-  # What's a test fixture? Well, tests do not live in a vacuum; rather,
-  # they're run against the code they are testing. Often, a collection
-  # of tests will run against a common set of data, also called a
-  # fixture. If they're all bundled into the same test class, they can
-  # all share the setting up and tearing down of that data, eliminating
-  # unnecessary duplication and making it much easier to add related
-  # tests.
-  #
-  # Test::Unit::TestCase wraps up a collection of test methods together
-  # and allows you to easily set up and tear down the same test fixture
-  # for each test. This is done by overriding #setup and/or #teardown,
-  # which will be called before and after each test method that is
-  # run. The TestCase also knows how to collect the results of your
-  # assertions into a Test::Unit::TestResult, which can then be reported
-  # back to you... but I'm getting ahead of myself. To write a test,
-  # follow these steps:
-  #
-  # * Make sure Test::Unit is in your library path.
-  # * require 'test/unit' in your test script.
-  # * Create a class that subclasses Test::Unit::TestCase.
-  # * Add a method that begins with "test" to your class.
-  # * Make assertions in your test method.
-  # * Optionally define #setup and/or #teardown to set up and/or tear
-  #   down your common test fixture.
-  # * You can now run your test as you would any other Ruby
-  #   script... try it and see!
-  #
-  # A really simple test might look like this (#setup and #teardown are
-  # commented out to indicate that they are completely optional):
-  #
-  #     require 'test/unit'
-  #     
-  #     class TC_MyTest < Test::Unit::TestCase
-  #       # def setup
-  #       # end
-  #     
-  #       # def teardown
-  #       # end
-  #     
-  #       def test_fail
-  #         assert(false, 'Assertion was false.')
-  #       end
-  #     end
-  #
-  #
-  # == Test Runners
-  #
-  # So, now you have this great test class, but you still need a way to
-  # run it and view any failures that occur during the run. This is
-  # where Test::Unit::UI::Console::TestRunner (and others, such as
-  # Test::Unit::UI::GTK::TestRunner) comes into play. The console test
-  # runner is automatically invoked for you if you require 'test/unit'
-  # and simply run the file. To use another runner, or to manually
-  # invoke a runner, simply call its run class method and pass in an
-  # object that responds to the suite message with a
-  # Test::Unit::TestSuite. This can be as simple as passing in your
-  # TestCase class (which has a class suite method). It might look
-  # something like this:
-  #
-  #    require 'test/unit/ui/console/testrunner'
-  #    Test::Unit::UI::Console::TestRunner.run(TC_MyTest)
-  #
-  #
-  # == Test Suite
-  #
-  # As more and more unit tests accumulate for a given project, it
-  # becomes a real drag running them one at a time, and it also
-  # introduces the potential to overlook a failing test because you
-  # forget to run it. Suddenly it becomes very handy that the
-  # TestRunners can take any object that returns a Test::Unit::TestSuite
-  # in response to a suite method. The TestSuite can, in turn, contain
-  # other TestSuites or individual tests (typically created by a
-  # TestCase). In other words, you can easily wrap up a group of
-  # TestCases and TestSuites like this:
-  #
-  #  require 'test/unit/testsuite'
-  #  require 'tc_myfirsttests'
-  #  require 'tc_moretestsbyme'
-  #  require 'ts_anothersetoftests'
-  #
-  #  class TS_MyTests
-  #    def self.suite
-  #      suite = Test::Unit::TestSuite.new
-#      suite << TC_MyFirstTests.suite
-#      suite << TC_MoreTestsByMe.suite
-#      suite << TS_AnotherSetOfTests.suite
-#      return suite
-#    end
-#  end
-#  Test::Unit::UI::Console::TestRunner.run(TS_MyTests)
-#
-# Now, this is a bit cumbersome, so Test::Unit does a little bit more
-# for you, by wrapping these up automatically when you require
-# 'test/unit'. What does this mean? It means you could write the above
-# test case like this instead:
-#
-#  require 'test/unit'
-#  require 'tc_myfirsttests'
-#  require 'tc_moretestsbyme'
-#  require 'ts_anothersetoftests'
-#
-# Test::Unit is smart enough to find all the test cases existing in
-# the ObjectSpace and wrap them up into a suite for you. It then runs
-# the dynamic suite using the console TestRunner.
-#
-#
-# == Questions?
-#
-# I'd really like to get feedback from all levels of Ruby
-# practitioners about typos, grammatical errors, unclear statements,
-# missing points, etc., in this document (or any other).
