-		    GNU GENERAL PUBLIC LICENSE
-		       Version 2, June 1991
+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:
 
- 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.
+  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.
 
-			    Preamble
+  2. You may modify your copy of the software in any way, provided that
+     you do at least ONE of the following:
 
-  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.
+       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.
 
-  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.
+       b) use the modified software only within your corporation or
+          organization.
 
-  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.
+       c) give non-standard binaries non-standard names, with
+          instructions on where to get the original software distribution.
 
-  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.
+       d) make other distribution arrangements with the author.
 
-  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.
+  3. You may distribute the software in object code or binary form,
+     provided that you do at least ONE of the following:
 
-  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.
+       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.
 
-  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.
+       b) accompany the distribution with the machine-readable source of
+	  the software.
 
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-		    GNU GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+       c) give non-standard binaries non-standard names, with
+          instructions on where to get the original software distribution.
 
-  0. This License 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".
+       d) make other distribution arrangements with the author.
 
-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.
+  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.
 
-  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.
+     For the list of those files and their copying conditions, see the
+     file LEGAL.
 
-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.
+  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.
 
-  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.
+  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.

+		    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!

+  have_header(header): check whether header file exists
+  create_makefile(target): generate Makefile
 
-以下の変数を使うことができます．
+The value of the variables below will affect the Makefile.
 
-  $CFLAGS: コンパイル時に追加的に指定するフラグ(-Iなど)
-  $LDFLAGS: リンク時に追加的に指定するフラグ(-Lなど)

+``create_makefile''.  The Makefile will not generated, compilation will
+not be done.
 
 (6) prepare depend (optional)
 
-もし，ディレクトリにdependというファイルが存在すれば，
-Makefileが依存関係をチェックしてくれます．
+If the file named depend exists, Makefile will include that file to
+check dependencies.  You can make this file by invoking

-  % ls > MANIFEST
+  % find * -type f -print > MANIFEST
   % vi MANIFEST

+Append file names into MANIFEST.  The compilation scheme requires
+MANIFEST only to exist, but it's better to take this step in order
+to distinguish which files are required.

-Rubyのディレクトリでmakeを実行するとMakefileを生成からmake，
-必要によってはそのモジュールのRubyへのリンクまで自動的に実行

+You don't need this step if you put the extension library under the ext
+directory of the ruby source tree.  In that case, compilation of the
+interpreter will do this step for you.

+
+to compile your extension.  You don't need this step either if you have
+put extension library under the ext directory of the ruby source tree.

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

+
+: open-uri.rb
+
+  Imported.  This is an easy-to-use wrapper for net/http and net/ftp.

+
+  Method is called when Class is inherited by another class.
+

+	def A.inherited(by)
+          puts "A inherited by #{by.inspect}"
+        end

+
+: Set class (set.rb)
+
+  Imported.
+
+: OptionParser module
+
+  Imported.  Command line options utility library.
+
+: parser
+
+  %W(...) notation, word list literal like %w(...) with the
+  exception that #{} interpolation is allowed.
+
+: parser
+
+  Now arbitrary statements are allowed inside #{} interpolation
+  without escapes.  In other hand, they can no longer access to
+  variables defined in eval.
+
+: parser
+
+  Digits preceded minus sign is a literal integer.
+
+: IO::sysopen
+
+  New method to get a raw file descriptor.
+
+: TCPServer#accept, UNIXServer#accept, Socket#accept
+
+  New methods to return an accepted socket fd.
+
+: Date and DateTime
+
+  lib/date.rb now provides both Date and DateTime.
+
+  Some methods have been renamed.  But the old names are still alive.
+
+  Some new methods have been added (Date::parse, Date#strftime, etc.).
+
+  Date#mjd now returns the chronological modified Julian day number.
+
+  All facilities about tjd have been removed.
+
+: Thread#join
+
+  Optional argument limits maximum time to wait the thread in second.
+  And returns nil if timed out.
+
+: Array#filter
+
+  Previously deprecated, now removed.  Use Array#collect!.
+
+: dl module
+
+  Imported. An interface to the dynamic linker.
+
+: IO#sysseek
+
+  Added.
+
+: IO
+
+  64bit off_t support by Janathan Baker.
+
+: abort()
+
+  Takes optional terminate message argument.
+
+: iconv module
+
+  Imported.  Wrapper library of (({iconv})).
+
+: IO.fsync
+
+  New method that copies all in-memory parts of a file to disk and
+  waits until the deice reports that all parts are on stable storage.
+  Implemented with fsync(2) or equivalent.
+
+: Dir#pos=
+
+  Returns the new position instead of self.
+
+: Dir::glob
+
+  Now accepts optional FNM_* flags via the second argument, whereas
+  Dir::[] doesn't.
+
+    Dir.glob("makefile", File::FNM_CASEFOLD) #=> ['Makefile', 'makefile']
+
+: fileutils module
+
+  Imported.  File utility library.
+
+: racc runtime module
+
+  Imported.  Racc runtime library. (Racc is a parser generator for ruby)
+
+: tsort module
+
+  Imported.  Topological sorting library.
+
+: stringio module
+
+  Imported.  Pseudo (({IO})) class from/to (({String})).
+
+: strscan module
+
+  Imported.  Fast string scanner library.
+
+: Array#pack, String#unpack
+
+  Allows comment in template strings.
+
+: Array#pack, String#unpack
+
+  New templates 'q' and 'Q' for 64bit integer (signed and unsigned respectively).
+
+: Array#new
+
+  Now takes block to fill initial values.  E.g.
+
+	Array.new(10) { |i| i + 1 }
+	=> [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
+
+: Array#fill
+
+  Takes block to get the values to fill.
+
+: Array#fetch
+
+  Takes block to get the default value.
+
+: Hash#update
+
+  Takes block to resolve key conflict.
+
+: IO#fsync
+
+  Added.
+
+: 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
+
+: allocation framework
+
+  any instance of class can be allocated by class.allocate,
+  (except a few classes).
+
+: break and next
+
+  Extended to take an optional expression, which is used as a value
+  for termination. [experimental]
+
+: 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.
+
+: expression parenthesis in the first argument
+
+  Experimentally 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]
+
+: pp module
+
+  Imported. Prity Printing library.
+
+: open
+
+  Extended so that when the third argument is permission flags it
+  calls open(2) instead of fopen(3).
+
+: Array#fetch(index [, default])
+
+  Added.  If a default value isn't given, raises index error if index
+  is out of range.
+
+: Array#insert(n, other, ...)
+
+  Added. [ruby-talk:14289]
+
+  This is much the same as (({ary[n,0] = [other,...]})) except
+  returing self.
+
+    ary = [0,1,2,3]
+    ary[2, 0] = [4, 5, 6]
+    p ary
+
+    ary = [0,1,2,3]
+    ary.insert(2, 4, 5, 6)
+    p ary
+
+: Array#sort!
+
+  Changed to always return self without checking whether the sequence
+  of the elements was modified or not.
+
+  Beware that this behavior is not guaranteed to continue in the
+  future.  Do not rely on its return value. [ruby-dev:12506]
+
+: Curses
+
+  Updated.  New methods and constants for using the mouse, character
+  attributes, colors and key codes have been added.
+
+: Dir#path
+
+  Added.
+
+: Dir.chdir
+
+  Extended to take a block.
+
+: Dir.glob
+
+  Made to support meta-character escaping by a backslash.  Wildcards
+  and spaces may now be escaped using a backslash.
+
+: Dir.open
+
+  Changed to return what the block returns when a block is given, just
+  as File.open does. (It always returned (({nil})) in 1.6 and
+  prior)
+
+: Dir.chdir
+
+  Changed to warn only when invoked from multiple threads or no block
+  is given. [ruby-dev:13823]
+
+    Dir.chdir('foo') {
+      Dir.chdir('bar') {   # previously warned
+        puts Dir.pwd
+      }
+    }
+
+: Enumerable#all?
+: Enumerable#any?
+: Enumerable#inject
+: Enumerable#sort_by
+
+  Added.
+
+: File#fnmatch, File::Constants::FNM_*
+
+  Added.  Refer to the fnmatch(3) manpage for details.
+
+  Localism is FNM_DOTMATCH which has the opposite meaning of the
+  commonly known FNM_PERIOD, which does not exist in Ruby.
+
+  e.g.
+
+    # exclude files matching "*.bak" case-insensitively.
+    files.reject! {|fn| File.fnmatch?("*.bak", fn, File::FNM_CASEFOLD) }
+
+: File.lchmod
+: File.lchown
+
+  Added.
+
+: File.open, IO.open
+
+  File mode can be specified by flags like open(2),
+  e.g. File::open(path, File::CREAT|File::WRONLY).
+
+: IO.open
+
+  Made public.  Can only associate an IO object with a file number
+  like IO.new and IO.for_fd, but can take a block.
+
+: IO.for_fd
+
+  Added as a synonym for IO.new.
+
+: IO.read
+
+  Added.  Like IO.readlines, except it returns the entire file as a
+  string.  [ruby-talk:9460]
+
+: Interrupt
+
+  Made a subclass of SignalException. (It was a subclass of
+  Exception in 1.6 and prior)
+
+: Marshal
+
+  Fixed not to dump anonymous classes/modules.
+
+  Fixed with loading modules.
+
+: MatchData#to_ary
+
+  Added for convenience of Regexp#match. [ruby-dev:12766]
+
+  Previously we had to do:
+
+    foo, bar, baz = /(\w+?)\s+(\w+?)\s+(\w+)/.match("foo bar baz").to_a[1..-1]
+    p [foo, bar, baz]
+
+  But now can do:
+
+    _, foo, bar, baz = /(\w+?)\s+(\w+?)\s+(\w+)/.match("foo bar baz")
+    p [foo, bar, baz]
+
+: Math.acos(x)
+: Math.asin(x)
+: Math.atan(x)
+: Math.cosh(x)
+: Math.hypot(x,y)
+: Math.sinh(x)
+: Math.tanh(x)
+
+  Added.
+
+: Method#==
+
+  Added.
+
+: Module#include?
+
+  Added. [ruby-dev:13941] 
+
+: Module#included
+
+  Added.  This is a hook called after Module#append_feature.
+
+: Module#method_removed
+: Module#method_undefined
+
+  Added.
+
+: Module.new, Class.new
+
+  Extended to take block.
+
+: Multiple assignment behavior
+
+  Fixed so that "*a = nil" results in "a == []".
+
+: Net::HTTP
+
+  New version of Net::HTTP has introduced seriously incompatible
+  changes. For details, see document embedded in net/http.rb itself.
+
+: NameError and NoMethodError
+
+  Moved and now NoMethodError < NameError < StandardError.
+
+: NoMethodError
+
+  Added. [ruby-dev:12763]
+
+: NotImplementError
+
+  Finally obsoleted.  Use NotImplementedError.
+
+: Object#singleton_method_removed
+: Object#singleton_method_undefined
+
+  Added.
+
+: Proc#==
+
+  Added.
+
+: Proc#yield
+
+  Added.  This is equivalent to Proc#call except it does not check the
+  number of given arguments, which are thus passed to the proc as-is.
+
+: Process.times
+
+  Moved from Time.times. (Time.times still remains but emits a
+  warning)
+
+: Process.waitall
+
+  Added.
+
+: Process::Status
+
+  Added.  (({$?})) is now an instance of this class.
+
+: Range#step([step=1])
+
+  Added.
+
+: Range#to_ary
+
+  Added.  You can now do something like this:
+
+    a, b, c = 1..3
+
+: Regexp#options
+
+  Added.
+
+: Regexp.last_match(n)
+
+  Extended to take an optional argument.
+
+: Signal
+
+  Added. This module has module functions Signal.trap and Signal.list.
+
+: Socket.pack_sockaddr_in, Socket.unpack_sockaddr_in
+
+  Added.  Utility for direct Socket access.
+
+: Socket.pack_sockaddr_un, Socket.unpack_sockaddr_un
+
+  Added.  Utility for direct Socket access.
+
+: String#[regexp, nth]
+
+  Extended to accepts optional second argument.
+
+  It tries match between self and REGEXP, then returns the
+  content of the NTH regexp register.
+
+: String#casecmp
+
+  Added.  This is a case insensitive version of String#<=>.
+
+: String#chomp
+
+  If $/ == "\n", chops off last newlines (any of \n, \r, \r\n).
+
+: String#eql?
+
+  Changed to be always case sensitive.
+
+: String#insert(n, other)
+
+  Added.
+
+  This is much the same as (({str[n, 0] = other})) except returing
+  self.
+
+: String#lstrip, rstrip, lstrip!, rstrip!
+
+  Added.  These strip only left or right part of a string.
+
+: String#match
+
+  Added.
+
+: String/Array methods
+
+  Returns an instance of receivers class.
+
+: String.new
+
+  The first argument becomes optional.
+
+: Symbol#intern
+
+  Added.
+
+: Symbol.all_symbols
+
+  Added. [ruby-dev:12921]
+
+: SystemCallError.===
+
+  Added. (See the "Comparison of exception classes in a rescue clause"
+  paragraph above) [ruby-dev:12670]
+
+: SystemExit#status
+
+  Added.
+
+: TCPServer#listen, UNIXServer#listen
+
+  Added.
+
+: TCPSocket.new
+: TCPSocket.open
+
+  Extended to take an address and a port number for the local side in
+  optional 3rd and 4th arguments.
+
+: Time
+
+  Extended to accept a negative time_t. (Only when the platform
+  supports it)
+
+    p Time.at(-1)
+    => Thu Jan 01 08:59:59 JST 1970
+
+: Time#to_a
+: Time#zone
+
+  Made to return "UTC" under gmtime.  It used to return a platform
+  dependent value, typically "GMT", in 1.6 and prior.
+
+To be investigated:
+
+ Sat Feb 24 03:15:49 2001  Yukihiro Matsumoto  <matz@ruby-lang.org>

+
+= 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	
+    Quits (sub)irb. 
+
+--- conf, irb_context
+    Displays current configuration. Modifing the configuration is
+    achieved by sending message to `conf'. 
+
+--- conf.eval_history = N
+    Sets execution result history.
+    N is a integer or nil. If N > 0, the number of historys is N. 
+    If N == 0, the number of historys is unlimited. If N is nill,
+    execution result history isn't used(default).
+
+--- conf.back_trace_limit
+    Sets display lines of backtrace as top n and tail n. 
+    The default value is 16.
+    
+--- conf.debug_level = N
+    Sets debug level of irb. 
+
+--- conf.ignore_eof = true/false
+    Whether ^D (control-d) will be ignored or not. 
+    If false is set, ^D means quit. 
+
+--- conf.ignore_sigint= true/false
+    Whether ^C (control-c) will be ignored or not. 
+    If false is set, ^D means quit.  If true, 
+      during input:   cancel inputing then return to top level. 
+      during execute: abondon current execution. 
+
+--- conf.inf_ruby_mode = true/false
+    Whether inf-ruby-mode or not. The default value is false.
+
+--- conf.inspect_mode = true/false/nil
+    Specifies inspect mode. 
+    true:  display inspect
+    false: display to_s
+    nil:   inspect mode in non math mode, 
+           non inspect mode in math mode. 
+
+--- conf.math_mode
+    Whether bc mode or not. 
+
+--- conf.use_loader = true/false
+    Whether irb's own file reader method is used when load/require or not. 
+    This mode is globaly affected (irb wide). 
+
+--- conf.prompt_c
+    prompt for a continuating statement (e.g, immediately after of `if')
+
+--- conf.prompt_i
+    standard prompt
+
+--- conf.prompt_s
+    prompt for a continuating string
+
+--- conf.rc
+    Whether ~/.irbrc is read or not. 
+
+--- conf.use_prompt = true/false
+    Prompting or not. 
+
+--- conf.use_readline = true/false/nil
+    Whether readline is used or not. 
+    true: uses 
+    false: doen't use
+    nil: intends to use readline except for inf-reuby-mode (default)
+#
+#--- conf.verbose=T/F
+#    Whether verbose messages are display or not. 
+
+--- cws, chws, irb_change_workspace [obj]
+    obj will be self. If obj is omitted, self will be home-object, or
+    the main object of first started irb.
+
+--- pushws, irb_pushws, irb_push_workspace [obj]
+    same as UNIX-shell command pushd.
+
+--- popws, irb_popws, irb_pop_workspace
+    same as UNIX-shell command popd
+
+--- irb [obj]
+    Invoke subirb. If obj is given, obj will be self. 
+
+--- jobs, irb_jobs
+    List of subirb
+
+--- fg n, irb_fg n
+    Switch into specified subirb. The following is candidates of n:
+
+      irb number
+      thhread
+      irb object
+      self(obj which is specified of irb obj)
+
+--- kill n, irb_kill n
+    Kill subirb. The means of n is as same as the case of irb_fg. 
+
+--- souce, irb_source  path
+    This is a like UNIX-shell command source. evaluate script in path
+    on current context.
+
+--- irb_load path, prev
+    irb-version of Ruby's load.
+
+= System variable
+
+--- _  The latest value of evaluation (it is local)
+--- __ The history of evaluation values.
+    __[line_no] return an evaluation value of line number<line_no>. If
+    line_no is a negative, return value before -<line_no> from latest
+    value.

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

+=begin
+= irbとは?
+
+irbはinteractive rubyの略です. rubyの式を標準入力から簡単に入力/実行する
+ためのツールです.
+
+= 起動
+
+  % irb
+
+で行ないます. 
+
+= 使い方
+
+irbの使い方は, Rubyさえ知っていればいたって簡単です. 基本的には irb と
+いうコマンドを実行するだけです. irbを実行すると, 以下のようなプロンプ
+トが表れてきます. 後は, rubyの式を入れて下さい. 式が完結した時点で実行
+されます.
+
+  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> 
+
+また, irbはReadlineモジュールにも対応しています. Readlineモジュールが
+インストールされている時には, それを使うのが標準の動作になります.
+
+= コマンドオプション
+
+  irb.rb [options] file_name opts
+  options:
+  -f		    ~/.irbrc を読み込まない.
+  -m		    bcモード(分数, 行列の計算ができる)
+  -d                $DEBUG をtrueにする(ruby -d と同じ)
+  -Kc		    ruby -Kcと同じ
+  -r load-module    ruby -r と同じ.
+  --verbose	    これから実行する行を表示する(デフォルト)
+  --noverbose	    これから実行する行を表示しない
+  --echo	    実行結果を表示する(デフォルト)
+  --noecho	    実行結果を表示しない
+  --inspect	    結果出力にinspectを用いる(bcモード以外はデフォルト). 
+  --noinspect	    結果出力にinspectを用いない.
+  --readline	    readlineライブラリを利用する.
+  --noreadline	    readlineライブラリを利用しない. デフォルトの動作は,
+		    inf-reuby-mode以外でreadlineライブラリを利用しよう
+		    とする. 
+  --prompt prompt-mode
+  --prompt-mode prompt-mode
+		    プロンプトモードを切替えます. 現在定義されているプ
+		    ロンプトモードは, default, simple, xmp, inf-rubyが
+		    用意されています. デフォルトはdefaultプロンプトモー
+		    ドになっています.
+			    
+  --inf-ruby-mode   emacsのinf-ruby-mode用のプロンプト表示を行なう. 特
+		    に指定がない限り, readlineライブラリは使わなくなる.
+  --simple-prompt
+		    非常にシンプルなプロンプトを用いるモードです.
+  --noprompt	    プロンプト表示を行なわない.
+  --tracer	    コマンド実行時にトレースを行なう.
+  --back-trace-limit n
+		    バックトレース表示をバックトレースの頭から n, 後ろ
+		    からnだけ行なう. デフォルトは16 
+  --irb_debug n	    irbのデバッグデバッグレベルをnに設定する(利用しな
+		    い方が無難でしょう).
+  -v, --version	    irbのバージョンを表示する
+
+= コンフィギュレーション
+
+irb起動時に``~/.irbrc''を読み込みます. もし存在しない場合は,
+``.irbrc'', ``irb.rc'', ``_irbrc'', ``$irbrc''の順にloadを試みます.
+
+オプションを設定する代わりに, 以下のコマンドでもデフォルトの動作を設定
+できます.
+
+  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
+
+== プロンプトの設定
+
+プロンプトをカスタマイズしたい時には, 
+
+   IRB.conf[:PROMPT]
+
+を用います. 例えば, .irbrcの中で下のような式を記述します:
+
+   IRB.conf[:PROMPT][:MY_PROMPT] = { # プロンプトモードの名前
+     :PROMPT_I => nil,		  # 通常のプロンプト
+     :PROMPT_S => nil,		  # 文字列などの継続行のプロンプト
+     :PROMPT_C => nil,		  # 式が継続している時のプロンプト
+     :RETURN => "    ==>%s\n"	  # リターン時のプロンプト
+   }
+
+プロンプトモードを指定したい時には,
+
+  irb --prompt my-prompt
+
+でそのプロンプトモードで起動されます. または, .irbrcに下式を記述しても
+OKです.
+
+  IRB.conf[:PROMPT_MODE] = :MY_PROMPT
+
+PROMPT_I, PROMPT_S, PROMPT_Cは, フォーマットを指定します.
+
+  %N	起動しているコマンド名が出力される.
+  %m	mainオブジェクト(self)がto_sで出力される.
+  %M	mainオブジェクト(self)がinspectされて出力される.
+  %l	文字列中のタイプを表す(", ', /, ], `]'は%wの中の時)
+  %NNi	インデントのレベルを表す. NNは数字が入りprintfの%NNdと同じ. 省
+	略可能
+  %NNn	行番号を表します.
+  %%    %
+
+例えば, デフォルトのプロンプトモードは:
+
+  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"
+  } 
+
+となっています.
+
+RETURNは, 現在のところprintf形式です. 将来仕様が変わるかも知れません.
+
+== サブirbの設定
+
+コマンドラインオプションおよびIRB.confは(サブ)irb起動時のデフォルトの
+設定を決めるもので, `5. コマンド'にあるconfで個別の(サブ)irbの設定がで
+きるようになっています.
+
+IRB.conf[:IRB_RC]にprocが設定されていると, サブirbを起動する時にその
+procをirbのコンテキストを引数として呼び出します. これによって個別のサ
+ブirbごとに設定を変えることができるようになります.
+
+
+= コマンド
+
+irb拡張コマンドは, 簡単な名前と頭に`irb_'をつけた名前と両方定義されて
+います. これは, 簡単な名前がoverrideされた時のためです.
+
+--- exit, quit, irb_exit	
+    終了する. 
+    サブirbの場合, そのサブirbを終了する.
+
+--- conf, irb_context
+    irbの現在の設定を表示する. 設定の変更は, confにメッセージを送るこ
+    とによって行なえる. 
+
+--- conf.eval_history = N
+    実行結果のヒストリ機能の設定.
+    nnは整数かnilで nn>0 であればその数だけヒストリにためる。nn==0の時は
+    無制限に記憶する、nilだとヒストリ機能はやめる(デフォルト). 
+
+--- Conf.back_trace_limit
+    バックトレース表示をバックトレースの頭からn, 後ろからnだけ行なう.
+    デフォルトは16
+    
+--- conf.debug_level = N
+    irb用のデバッグレベルの設定
+
+--- conf.ignore_eof = true/false
+    ^Dが入力された時の動作を設定する. trueの時は^Dを無視する, falseの
+    時はirbを終了する. 
+
+--- conf.ignore_sigint= true/false
+    ^Cが入力された時の動作を設定する. false時は, irbを終了する. trueの
+    時の動作は以下のようになる:
+      入力中: これまで入力したものをキャンセルしトップレベルに戻る. 
+      実行中: 実行を中止する.
+
+--- conf.inf_ruby_mode = true/false
+    inf-ruby-mode用のプロンプト表示を行なう. デフォルトはfalse.
+
+--- conf.inspect_mode = true/false/nil
+    インスペクトモードを設定する.
+    true: インスペクトして表示する.
+    false: 通常のprintで表示する.
+    nil: 通常モードであれば, inspect modeとなり, mathモードの時は, non
+	 inspect modeとなる.   
+
+--- conf.math_mode
+    参照のみ. bcモード(分数, 行列の計算ができます)かどうか?
+
+--- conf.use_loader = true/false
+    load/require時にirbのfile読み込み機能を用いるモードのスイッチ(デフォ
+    ルトは用いない). このモードはIRB全体に反映される.
+
+--- conf.prompt_c
+    ifの直後など, 行が継続している時のプロンプト.
+
+--- conf.prompt_i
+    通常のプロンプト.
+
+--- conf.prompt_s
+    文字列中などを表すプロンプト.
+
+--- conf.rc
+    ~/.irbrcを読み込んだかどうか?

+= 使用上の制限
+
+irbは, 評価できる時点(式が閉じた時点)での逐次実行を行ないます. したがっ
+て, rubyを直接使った時と, 若干異なる動作を行なう場合があります.
+
+現在明らかになっている問題点を説明します.
+
+== ローカル変数の宣言
+
+rubyでは, 以下のプログラムはエラーになります.
+
+  eval "foo = 0"
+  foo
+  --
+  -:2: undefined local variable or method `foo' for #<Object:0x40283118> (NameError)
+  ---
+  NameError
+
+ところが, irbを用いると
+
+  >> eval "foo = 0"
+  => 0
+  >> foo
+  => 0
+
+となり, エラーを起こしません. これは, rubyが最初にスクリプト全体をコン
+パイルしてローカル変数を決定するからです. それに対し, irbは実行可能に
+なる(式が閉じる)と自動的に評価しているからです. 上記の例では, 
+
+  evel "foo = 0" 
+
+を行なった時点で評価を行ない, その時点で変数が定義されるため, 次式で 
+変数fooは定義されているからです.
+
+このようなrubyとirbの動作の違いを解決したい場合は, begin...endで括って
+バッチ的に実行して下さい:
+
+  >> begin
+  ?>   eval "foo = 0"
+  >>   foo
+  >> end
+  NameError: undefined local variable or method `foo' for #<Object:0x4013d0f0>
+  (irb):3
+  (irb_local_binding):1:in `eval'
+
+== ヒアドキュメント
+
+現在のところヒアドキュメントの実装は不完全です. 
+
+== シンボル
+
+シンボルであるかどうかの判断を間違えることがあります. 具体的には式が完了
+しているのに継続行と見なすことがあります.

+= 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)
