-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 2, June 1991
 
-  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, 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.
 
-  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 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.
 
-       b) use the modified software only within your corporation or
-          organization.
+  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.
 
-       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 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.
 
-  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.
+  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.
 
-       c) give non-standard binaries non-standard names, with
-          instructions on where to get the original software distribution.
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
 
-       d) make other distribution arrangements with the author.
+  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".
 
-  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.
+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.
 
-     For the list of those files and their copying conditions, see the
-     file LEGAL.
+  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.
 
-  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.
+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.
 
-  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.
+  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) 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 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) 19yy 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 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!

-* discourage use of symbol variables (e.g. $/, etc.) in manual
-* discourage use of Perlish features by giving warnings.
-* non confusing in-block local variable (is it possible?)
-  + remove scope by block
-  + variables appears within block may have independent values.
-* Regexp: make /o thread safe.
-* decide whether begin with rescue or ensure make do..while loop.
-* a +1 to be a+1, not a(+1).
-* unify == and eql? again
-* to_i returns nil if str contains no digit.
-* raise exception by `` error
-* jar like combined library package. -> RubyGems?
-* resumable Exception via Exception#resume.
-* method combination, e.g. before, after, around, etc.
-* .. or something like defadvice in Emacs.
-* property - for methods, or for objects in general.
-* "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()"
-* clarify evaluation order of operator argument (=~, .., ...)
-* :symbol => value hash in the form of {symbol: value, ...} ??
 
 Hacking Interpreter
 
-- generational GC
-* non-blocking open (e.g. for named pipe) for thread
-* avoid blocking with gethostbyname/gethostbyaddr (use fork ???)
-* objectify interpreters ???
+* non-blocking open (e.g. named pipe) for thread
+* avoid blocking with gethostbyname/gethostbyaddr
+* objectify interpreters
 * remove rb_eval() recursions
 * syntax tree -> bytecode ???
 * scrambled script, or script filter
 * setuid ruby
-* performance tune for in-block (dynamic) local variables.
-* give warnings to assign magic variables.
-* export rb_io_{addstr,printf,puts,print}
-* autoload should work with threads [ruby-talk:4589]
-* remove stdio dependency from IOs.
-* warn for inconsistent local variable usage (lv m and method m at the same time). 
-* MicroRuby
-* Built-in Interactive Ruby.
-* Parser API
-* trap every method invocation, which can be enabled by e.g. trap_call :method.
-* unify Errno exceptions of same errno, or new exception comparison scheme.
-* 2.times{|i| if i==0 then a = 15 else puts eval("a") end} should print nil.
-* Thread#max_stack_size attribute (possible??)
 
 Standard Libraries
 
-- Module#define_method which takes a name and a body (block, proc or method).
-- Enume#inject
-- Array#fetch
-- IO::for_fd
-- Process::waitall [ruby-talk:4557]
-- Process::Status
-- File::lchown, File::lchmod; xxx - still need work for non existing platforms
-- move Time::times to Process.
-- Enumerable#sort_by for Schwartzian transformation
-- 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.
 * String#scanf(?)
 * Object#fmt(?)
 * Time::strptime
 * Integer[num], Float[num];  Fixnum[num]?
-* method to retrieve non-number trailer for to_i/to_f.
+* method to detect non-number trailer for to_i/to_f.
 * Stream or Port, abstract superclass of IO ?
 * String#{pred,prev}, String#downto
 * optional stepsize argument for succ()
-* Ruby module -- Ruby::Version, Ruby::Interpreter
-* introduce Boolean class; super of TrueClass, FalseClass
-* 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.
-* require "1.6" etc. by /usr/lib/ruby/1.6/1.6.rb ;-)
-* save both "feature names" and "normalized path" in $"
-* implement Mutex_m (or MutexMixin) using Mutex.

-(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
-      * <install_directory>\lib\ruby
-      * <install_directory>\lib\ruby\<MAJOR>.<MINOR>
-      * <install_directory>\lib\ruby\<MAJOR>.<MINOR>\<PLATFORM>
-      * <install_directory>\lib\ruby\site_ruby
-      * <install_directory>\lib\ruby\site_ruby\<MAJOR>.<MINOR>
-      * <install_directory>\lib\ruby\site_ruby\<MAJOR>.<MINOR>\<PLATFORM>
-      * <install_directory>\man\man1
-    If Ruby's version is `x.y.z', the ((|<MAJOR>|)) is `x' and the ((|<MINOR>|)) is `y'.
-    The ((|<PLATFORM>|)) is usually `(({i586-bccwin32}))'.
-
-== 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 == []".

-
-  Added. [ruby-talk:14289]
-
-  This is much the same as (({ary[n,0] = [other,...]})) except

-
-    ary = [0,1,2,3]
-    ary[2, 0] = [4, 5, 6]

-    ary.insert(2, 4, 5, 6)
-    p ary
-
-: Array#sort!
-
-  Changed to always return self without checking whether the sequence

-
-  Added.
-
-  This is much the same as (({str[n, 0] = other})) except returing
-  self.
-

-
-  Changed to warn only when invoked from multiple threads or no block
-  is given. [ruby-dev:13823]

-
-: Marshal to use marshal_dump and marshal_load
-
-  if a dumping object responds to 'marshal_dump', Marshal.dump calls

-  Added. [ruby-dev:12763]
-
-: NotImplementError
-
-  Finally obsoleted.  Use NotImplementedError.

-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

-= 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.
-
---- Shell#blockdev?(file)
---- Shell#chardev?(file)
---- Shell#directory?(file)
---- Shell#executable?(file)
---- Shell#executable_real?(file)
---- Shell#exist?(file)/Shell#exists?(file)

-= 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>)))

-<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.

-<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.

-<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.

-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.

-<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>

-<H2>Internal structure</H2>
-BigDecimal number is defined by the structure Real in BigDecimal.h.
-Digits representing a float number are kept in the array frac[] defined in the structure.
-In the program,any floating number(BigDecimal number) is represented as:<BR>
- <BigDecimal number> = 0.xxxxxxxxx*BASE**n<BR><BR>
-where 'x' is any digit representing mantissa(kept in the array frac[]),
-BASE is base value(=10000 in 32 bit integer system),

-Larger BASE value enables smaller size of the array frac[],and increases computation speed.
-The value of BASE is defined ind VpInit(). In 32 bit integer system,this value is

-BigDecimal has not yet been compiled and tested on 64 bit integer system.

-<H2>Binary or decimal number representation</H2>
-I adopted decimal number representation for BigDecimal implementation.
-Of cource,binary number representation is common on the most computers.

-<H3>Advantages using decimal representation</H3>
-The reason why I adopted decimal number representation for BigDecimal is:<BR>
-<DL>
-<DT>Easy for debugging
-<DD>The floating number 1234.56784321 can be easily represented as:<BR>
-  frac[0]=1234,frac[1]=5678,frac[2]=4321,exponent=1,and sign=2.

-<CODE><PRE>
-   file = File::open(....,"r")
-   s = BigDecimal::new("0")

-If the internal representation is binary,translation from decimal to 
-binary is required and the translation error is inevitable.
-For example, 0.1 can not exactly be represented in binary.<BR>
-0.1 => b1*2**(-1)+b1*2**(-2)+b3*2**(-3)+b4*2**(-4)....<BR>
-where b1=0,b2=0,b3=0,b4=1...<BR>
-bn(n=1,2,3,...) is infinite series of digit with value of 0 or 1,
-and rounding operation is necessary but where we should round the series ?
-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.
-</DL>
-
-<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.
-
-<H4>Which is the first input?</H4>
-Because most people uses decimal notatin for numeric data representation,
-BigDecimal can handle numeric data without loss of translation error.

-For the fundamental arithmetics such as addition,subtraction,

-<H3>1. +,-,*,/</H3>
-For the operation + - * /,you can not specify the resulting

-For example, c has more than 100 siginificant digits if c is computed as:<BR>
-c = 0.1+0.1*10**(-100)<br>
-<BR>
-As +,-,and * are always exact(no round operation is performed unless BigDecimal.limit is specified),
-which means more momories are required to keep computation results.
-But,the division such as c=1.0/3.0 will always be rounded.<BR>
-
-<H3>2. add,sub,mult,div</H3>
-The length of the significant digits obtained from +,-,*,/

-Ruby には Bignum というクラスがあり、数百桁の整数でも計算することができます。
-ただ、任意桁の浮動少数点演算用クラスが無いようです。そこで、
-任意桁の浮動少数点演算用拡張ライブラリ BigDecimal を作成しました。
-不具合や助言・提案がある場合どしどし、
-<A HREF="mailto:shigeo@tinyforest.gr.jp">shigeo@tinyforest.gr.jp</A>
-までお知らせください。不具合を直す気は大いにあります。ただ、時間などの関係で約束

-<H3>メソッド一覧</H3>
-以下のメソッドが利用可能です。
-「有効桁数」とは BigDecimal が精度を保証する桁数です。
-ぴったりではありません、若干の余裕を持って計算されます。
-また、例えば３２ビットのシステムでは１０進で４桁毎に計算します。従って、現状では、
-内部の「有効桁数」は４の倍数となっています。
-<P>
-以下のメソッド以外にも、(C ではない) Ruby ソースの形で
-提供されているものもあります。例えば、
-<CODE><PRE>
-require "bigdecimal/math.rb"
-</PRE></CODE>
-とすることで、sin や cos といった関数が使用できるようになります。
-使用方法など、詳細は math.rb の内容を参照して下さい。
-
-その他、Float との相互変換などのメソッドが util.rb でサポートされています。
-利用するには
-<CODE><PRE>
