+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
 
-       d) make other distribution arrangements with the author.
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
 
-  3. You may distribute the software in object code or binary form,
-     provided that you do at least ONE of the following:
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
 
-       a) distribute the binaries and library files of the software,
-	  together with instructions (in the manual page or equivalent)
-	  on where to get the original distribution.
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
 
-       b) accompany the distribution with the machine-readable source of
-	  the software.
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
 
-       c) give non-standard binaries non-standard names, with
-          instructions on where to get the original software distribution.
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
 
-       d) make other distribution arrangements with the author.
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
 
-  4. You may modify and include the part of the software into any other
-     software (possibly commercial).  But some files in the distribution
-     are not written by the author, so that they are not under these terms.
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
 
-     For the list of those files and their copying conditions, see the
-     file LEGAL.
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
 
-  5. The scripts and library files supplied as input to or produced as 
-     output from the software do not automatically fall under the
-     copyright of the software, but belong to whomever generated them, 
-     and may be sold commercially, and may be aggregated with this
-     software.
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
 
-  6. THIS SOFTWARE IS PROVIDED "AS IS" AND WITHOUT ANY EXPRESS OR
-     IMPLIED WARRANTIES, INCLUDING, WITHOUT LIMITATION, THE IMPLIED
-     WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-     PURPOSE.
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	    How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) 19yy  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) 19yy name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Library General
+Public License instead of this License.

-	  1) Prohibit incremental GC while running Ruby-level finalizers

-	  This patch can introduce another memory consuming issue because
-	  Ruby-level finalizers can run after (2), GC is disabled.
-	  However, basically object consistency was broken at (2) as I
-	  described above. So that running Ruby-level finalizers contains
-	  danger originally. Because of this point, I need to suggest to
-	  remove these 3 lines (invoking remaining finalizers). And add a
-	  rule to add that finalizers should not add new finalizers, or
-	  say there is no guarantee to invoke finalizers that added by
-	  another finalizer.

-                    GNU GENERAL PUBLIC LICENSE
-                       Version 2, June 1991
-
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
- 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 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 Lesser 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.,
-    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 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 Lesser General
-Public License instead of this License.

-=== Language changes
-
-* nil/true/false
-  * nil/true/false objects are frozen. [Feature #8923]
-
-* Hash literal
-  * Symbol key followed by a colon can be quoted. [Feature #4276]
-
-* default argument
-  fixed a very longstanding bug that an optional argument was not
-  accessible in its default value expression.  [Bug #9593]
-
-=== Core classes updates (outstanding ones only)
-
-* Binding
-  * New methods:
-    * Binding#local_variables
-    * Binding#receiver
-
-* Dir
-  * New methods:
-    * Dir#fileno
-
-* Enumerable
-  * New methods:

-    * Enumerable#slice_when
-  * Extended methods:
-    * min, min_by, max and max_by supports optional argument to return
-      multiple elements.
-
-* Float
-  * New methods:
-    * Float#next_float
-    * Float#prev_float
-
-* File
-  * New methods:
-    * File.birthtime
-    * File#birthtime
-
-* File::Stat
-  * New methods:
-    * File::Stat#birthtime
-
-* GC
-  * GC.latest_gc_info returns :state to represent current GC status.
-  * Improvements
-    * Introduce incremental marking for major GC. [Feature #10137]
-
-* IO
-  * Improvements
-    * IO#nonblock_read and IO#nonblock_write for pipes on Windows are supported.
-
-* Kernel

-      there is no corresponding catch block, instead of ArgumentError.
-
-* Process
-  * Extended method:
-    * Process execution methods such as Process.spawn opens the file in write
-      mode for redirect from [:out, :err].
-

-    * String#unicode_normalize
-    * String#unicode_normalize!
-    * String#unicode_normalized?
-
-* Symbol
-  * Improvements
-    * Most symbols which are returned by String#to_sym and

-
-=== Core classes compatibility issues (excluding feature bug fixes)
-
-* Enumerable
-  * Enumerable#slice_before's state management deprecated.
-  * Enumerable#chunk's state management deprecated.
-
-* GC
-  * incompatible changes:
-    * Rename GC.stat entries. [Feature #9924]
-      See https://docs.google.com/spreadsheets/d/11Ua4uBr6o0k-nORrZLEIIUkHJ9JRzRR0NyZfrhEEnc8/edit?usp=sharing
-
-* Hash
-  * incompatible changes:
-    * Change overriding policy for duplicated key. [Bug #10315]
-      { **hash1, **hash2 } contains values of hash2 for duplicated keys.
-
-* IO
-  * incompatible changes:
-    * When flushing file IO with IO#flush, you cannot assume that the metadata
-      of the file is updated immediately.  On some platforms (especially
-      Windows), it is delayed until the filesystem load is decreased.
-      Use IO#fsync if you want to guarantee updating metadata.
-  * IO#each_codepoint raises an exception at incomplete character
-    before EOF when conversion takes place.  [Bug #11444]
-
-* Math
-  * incompatible changes:
-    * Math.log now raises Math::DomainError instead of returning NaN if the
-      base is less than 0, and returns NaN instead of -infinity if both of
-      two arguments are 0.
-    * Math.atan2 now returns values like as expected by C99 if both two
-      arguments are infinity.
-
-* Proc
-  * incompatible changes:
-    * ArgumentError is no longer raised when lambda Proc is passed as a
-      block, and the number of yielded arguments does not match the formal
-      arguments of the lambda, if just an array is yielded and its length
-      matches.
-
-* Process
-  * Process execution methods such as Process.spawn opens the file in write
-    mode for redirect from [:out, :err].
-    Before Ruby 2.2, it was opened in read mode.
-
-=== Stdlib updates (outstanding ones only)
-
-* Continuation
-  * callcc is obsolete. use Fiber instead.
-
-* Digest
-
-  * Digest() should now be thread-safe.  If you have a problem with
-    regard to on-demand loading under a multi-threaded environment,
-    preload "digest/*" modules on boot or use this method instead of
-    directly referencing Digest::*.
-  * Digest::HMAC has been removed just as previously noticed.
-
-* DL
-  * DL has been removed from stdlib. Please use Fiddle instead!
-
-* Etc
-  * New methods:
-    * Etc.uname
-    * Etc.sysconf
-    * Etc.confstr
-    * IO#pathconf
-    * Etc.nprocessors
-
-* Find, Pathname
-  * Extended methods:
-    * find method accepts "ignore_error" keyword argument.
-
-* Matrix
-  * New methods:
-    * Matrix#first_minor(row, column) returns the submatrix obtained
-      by deleting the specified row and column.
-    * Matrix#cofactor(row, column) returns the (row, column) cofactor
-      which is obtained by multiplying the first minor by (-1)**(row + column).
-    * Matrix#adjugate returns the adjugate of the matrix.
-    * hstack and vstack are new instance and class methods to stack matrices
-      horizontally and vertically.
-    * Matrix#laplace_expansion(row_or_column: num) returns the laplace_expansion
-      along the +num+ -th row or column.
-    * Vector.basis(size:, index:) returns the specified basis vector.
-    * Unary - and + added for Vector and Matrix.
-    * Vector#cross_product generalized to arbitrary dimensions.
-    * Vector#dot and #cross are aliases for #inner_product and #cross_product.
-    * Vector#angle_with returns the angle with its argument
-    * New instance and class method independent? to test linear independence.
-
-* Pathname
-  * Pathname#/ is aliased to Pathname#+.
-  * New methods:
-    * Pathname#birthtime
-
-* Rake
-  * Updated to Rake 10.4.0.  For full release notes see:

-
-* ext/date/lib/date/format.rb
-  * Removed because it's empty file.
-
-* Digest
-  * Digest::HMAC has finally ceased to exist.  Use OpenSSL::HMAC or an external gem instead.
-
-* time.rb
-  * Time.parse, Time.strptime, Time.rfc2822, Time.xmlschema may produce
-    fixed-offset Time objects.
-    It is happen when usual localtime doesn't preserve the offset from UTC.
-  * Time.httpdate produces always UTC Time object.
-  * Time.strptime raises ArgumentError when no date information.
-
-* lib/rational.rb
-  * Removed because it is deprecated from 2009.
-
-* lib/complex.rb
-  * Removed because it is deprecated from 2009.

-* struct RRational is hidden.  [Feature #9513]
-  Use rb_rational_num and rb_rational_den instead.
-
-* rb_big_new and rb_big_resize takes a size_t instead of long.
-
-* rb_num2long returns a long instead of SIGNED_VALUE.
-
-* rb_num2ulong returns an unsigned long instead of VALUE.
-
-* st hash table uses power-of-two sizes for speed [Feature #9425].
-  Lookups are 10-25% faster if using appropriate hash functions.
-  However, weaknesses in hash distribution can no longer be masked
-  by prime number-sized tables, so extensions may need to tweak
-  hash functions to ensure good distribution.
-
-* rb_sym2str() added. This is almost same as `rb_id2str(SYM2ID(sym))`
-  but not pinning a dynamic symbol.
-
-* rb_str_cat_cstr() added. This is same as `rb_str_cat2()`.
-
-* `rb_str_substr()` and `rb_str_subseq()` will share middle of a string,
-  but not only the end of a string, in the future.  Therefore, result
-  strings may not be NUL-terminated, `StringValueCStr()` is needed
-  calling to obtain a NUL-terminated C string.
-
-* rb_tracepoint_new() supports new internal events accessible only from C:
-  * RUBY_INTERNAL_EVENT_GC_ENTER
-  * RUBY_INTERNAL_EVENT_GC_EXIT
-    r47528
-
-* rb_hash_delete() now does not call the block given to the current method.
-
-* rb_extract_keywords() and rb_get_kwargs() exported.  See README.EXT
-  for details.
-
-=== Build system updates
-
-* jemalloc is optionally supported via `./configure --with-jemalloc`
-  jemalloc may be suitable when system malloc is slow or prone
-  to fragmentation.  [Feature #9113]
-
-=== Implementation changes
-
-* GC
-    * Most symbols which are returned by String#to_sym and
-      String#intern are GC-able [Feature #9634]
-    * Introduce incremental marking for major GC. [Feature #10137]
-    * Enable lazy sweep on GC caused by malloc().
-
-* VM
-    * Use frozen string literals for Hash#[] and Hash#[]=
-    * Fast keyword arguments passing [Feature #10440]
-    * Allow to receive huge splatted array by a rest argument
-      [Feature #10440]
-
-* Process
-    * Process creation methods, such as spawn(), uses vfork() system call.
-      vfork() is faster than fork() when the parent process uses huge memory.

+* What's Ruby
+
+Ruby is the interpreted scripting language for quick and
+easy object-oriented programming.  It has many features to
+process text files and to do system management tasks (as in
+Perl).  It is simple, straight-forward, and extensible.
+
+* Features of Ruby
+
+  + Simple Syntax
+  + *Normal* Object-Oriented features(ex. class, method calls)
+  + *Advanced* Object-Oriented features(ex. Mix-in, Singleton-method)
+  + Operator Overloading
+  + Exception Handling
+  + Iterators and Closures
+  + Garbage Collection
+  + Dynamic Loading of Object files(on some architecture)
+  + Highly Portable(works on many UNIX machines, and on DOS,
+    Windows, Mac, BeOS etc.)
+
+* How to get Ruby
+
+The Ruby distribution can be found on:
+
+  ftp://ftp.netlab.co.jp/pub/lang/ruby/
+
+You can get it by anonymous CVS.  How to check out is:
+
+  $ cvs -d :pserver:anonymous@cvs.ruby-lang.org:/src login
+  (Logging in to anonymous@cvs.ruby-lang.org)
+  CVS password: anonymous
+  $ cvs -z4 -d :pserver:anonymous@cvs.ruby-lang.org:/src checkout ruby
+
+* Mailing list
+
+There is a mailing list to talk about Ruby.
+To subscribe this list, please send the following phrase
+
+	subscribe YourFirstName YourFamilyName
+e.g.
+        subscribe Joseph Smith
+
+in the mail body (not subject) to the address <ruby-talk-ctl@ruby-lang.org>.
+
+* How to compile and install
+
+This is what you need to do to compile and install Ruby:
+
+  1. If ./configure does not exist or is older than configure.in,
+     run autoconf to (re)generate configure.
+
+  2. Run ./configure, which will generate config.h and Makefile.
+
+  3. Edit defines.h if you need.  Probably this step will not need.
+
+  4. Remove comment mark(#) before the module names from ext/Setup (or
+     add module names if not present), if you want to link modules
+     statically.
+
+     If you don't want to compile non static extension modules
+     (probably on architectures which does not allow dynamic loading),
+     remove comment mark from the line "#option nodynamic" in
+     ext/Setup.
+
+  5. Run make.
+
+  6. 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).
+
+  7. Run 'make install'
+
+     You may have to be a super user to install ruby.
+
+If you fail to compile ruby, please send the detailed error report with
+the error log and machine/OS type, to help others.

 This document explains how to make extension libraries for Ruby.
 
-= Basic Knowledge
+1. Basic knowledge
 
 In C, variables have types and data do not have types.  In contrast,
-Ruby variables do not have a static type, and data themselves have
-types, so data will need to be converted between the languages.
-
-Data in Ruby are represented by the C type `VALUE'.  Each VALUE data
-has its data type.
-
-To retrieve C data from a VALUE, you need to:
-
-1. Identify the VALUE's data type
-2. Convert the VALUE into C data
-
-Converting to the wrong data type may cause serious problems.
-
-== Data Types
-
-The Ruby interpreter has the following data types:
-
-T_NIL       :: nil
-T_OBJECT    :: ordinary object
-T_CLASS     :: class
-T_MODULE    :: module
-T_FLOAT     :: floating point number
-T_STRING    :: string
-T_REGEXP    :: regular expression
-T_ARRAY     :: array
-T_HASH      :: associative array
-T_STRUCT    :: (Ruby) structure
-T_BIGNUM    :: multi precision integer
-T_FIXNUM    :: Fixnum(31bit or 63bit integer)
-T_COMPLEX   :: complex number
-T_RATIONAL  :: rational number
-T_FILE      :: IO
-T_TRUE      :: true
-T_FALSE     :: false
-T_DATA      :: data
-T_SYMBOL    :: symbol
-
-In addition, there are several other types used internally:
-
-T_ICLASS    :: included module
-T_MATCH     :: MatchData object
-T_UNDEF     :: undefined
-T_NODE      :: syntax tree node
-T_ZOMBIE    :: object awaiting finalization
+Ruby variables do not have static type and data themselves have
+types.  So, data need to be converted across the languages.
+
+Data in Ruby represented C type `VALUE'.  Each VALUE data have its
+data-type.
+
+To retrieve an C data from the VALUE, you need to:
+
+ (1) Identify VALUE's data type
+ (2) Convert VALUE into C data
+
+Converting to wrong data type may cause serious problems.
+
+
+1.1 Data-types
+
+Ruby interpreter has data-types as below:
+
+	T_NIL		nil
+	T_OBJECT	ordinary object
+	T_CLASS		class
+	T_MODULE	module
+	T_FLOAT		floating point number
+	T_STRING	string
+	T_REGEXP	regular expression
+	T_ARRAY		array
+	T_FIXNUM	Fixnum(31bit integer)
+	T_HASH		associative array
+	T_STRUCT	(Ruby) structure
+	T_BIGNUM	multi precision integer
+	T_TRUE		true
+	T_FALSE		false
+	T_DATA		data
+	T_SYMBOL        symbol
+
+Otherwise, there are several other types used internally:
+
+	T_ICLASS
+	T_MATCH
+	T_UNDEF
+	T_VARMAP
+	T_SCOPE
+	T_NODE
 
 Most of the types are represented by C structures.

-== Convert VALUE into C Data
+1.3 Convert VALUE into C data
 
-The data for type T_NIL, T_FALSE, T_TRUE are nil, false, true
+The data for type T_NIL, T_FALSE, T_TRUE are nil, true, false
 respectively.  They are singletons for the data type.
-The equivalent C constants are: Qnil, Qfalse, Qtrue.
-Note that Qfalse is false in C also (i.e. 0), but not Qnil.
-
-The T_FIXNUM data is a 31bit or 63bit length fixed integer.
-This size depends on the size of long: if long is 32bit then
-T_FIXNUM is 31bit, if long is 64bit then T_FIXNUM is 63bit.
-T_FIXNUM can be converted to a C integer by using the
-FIX2INT() macro or FIX2LONG().  Though you have to check that the
-data is really FIXNUM before using them, they are faster.  FIX2LONG()
-never raises exceptions, but FIX2INT() raises RangeError if the
-result is bigger or smaller than the size of int.
-There are also NUM2INT() and NUM2LONG() which converts any Ruby
-numbers into C integers.  These macros include a type check,
-so an exception will be raised if the conversion failed.  NUM2DBL()
-can be used to retrieve the double float value in the same way.
-
-You can use the macros
-StringValue() and StringValuePtr() to get a char* from a VALUE.
-StringValue(var) replaces var's value with the result of "var.to_str()".
-StringValuePtr(var) does the same replacement and returns char*
-representation of var.  These macros will skip the replacement if var
-is a String.  Notice that the macros take only the lvalue as their
-argument, to change the value of var in place.
-
-You can also use the macro named StringValueCStr(). This is just
-like StringValuePtr(), but always add NUL character at the end of
-the result. If the result contains NUL character, this macro causes
-the ArgumentError exception.
-StringValuePtr() doesn't guarantee the existence of a NUL at the end
-of the result, and the result may contain NUL.
+
+The T_FIXNUM data is the 31bit length fixed integer (63bit length on
+some machines), which can be convert to the C integer by using
+FIX2INT() macro.  There also be NUM2INT() which converts any Ruby
+numbers into C integer.  The NUM2INT() macro includes type check, so
+the exception will be raised if conversion failed.
 
 Other data types have corresponding C structures, e.g. struct RArray
-for T_ARRAY etc. The VALUE of the type which has the corresponding
-structure can be cast to retrieve the pointer to the struct.  The
-casting macro will be of the form RXXXX for each data type; for
-instance, RARRAY(obj).  See "ruby.h".  However, we do not recommend
-to access RXXXX data directly because these data structures are complex.
-Use corresponding rb_xxx() functions to access the internal struct.
-For example, to access an entry of array, use rb_ary_entry(ary, offset)
-and rb_ary_store(ary, offset, obj).
-
-There are some accessing macros for structure members, for example
-`RSTRING_LEN(str)' to get the size of the Ruby String object.  The
-allocated region can be accessed by `RSTRING_PTR(str)'.
+for T_ARRAY etc.  VALUE of the type which has corresponding structure

+Ruby String object.  The allocated region can be accessed by
+`RSTRING(str)->ptr'.  For arrays, `RARRAY(ary)->len' and
+`RARRAY(ary)->ptr' respectively.
 
 Notice: Do not change the value of the structure directly, unless you
-are responsible for the result.  This ends up being the cause of

+should be pointers to the structures which Ruby knows.  The known
 structures are defined in <ruby.h>.
 
-To convert C numbers to Ruby values, use these macros:
-
-INT2FIX() :: for integers within 31bits.
-INT2NUM() :: for arbitrary sized integers.
-
-INT2NUM() converts an integer into a Bignum if it is out of the FIXNUM
-range, but is a bit slower.
-
-== Manipulating Ruby Data
-
-As I already mentioned, it is not recommended to modify an object's
-internal structure.  To manipulate objects, use the functions supplied
-by the Ruby interpreter. Some (not all) of the useful functions are
-listed below:

-
-  Defines a method for the class.  func is the function pointer.  argc
-  is the number of arguments.  if argc is -1, the function will receive
-  3 arguments: argc, argv, and self.  if argc is -2, the function will
-  receive 2 arguments, self and args, where args is a Ruby array of
-  the method arguments.
-
-rb_define_private_method(VALUE klass, const char *name, VALUE (*func)(), int argc) ::

-
-    param-arg-spec := pre-arg-spec [post-arg-spec] / post-arg-spec /

-                                            ; captured as a ruby array
-    num-of-trailing-mandatory-args := DIGIT ; The number of trailing

-                                            ; converted to a hash with
-                                            ; #to_hash.  When the last
-                                            ; argument is nil, it is

-                                            ; is not specified and

-                                            ; given
-
-  For example, "12" means that the method requires at least one
-  argument, and at most receives three (1+2) arguments.  So, the format
-  string must be followed by three variable references, which are to be
-  assigned to captured arguments.  For omitted arguments, variables are
-  set to Qnil.  NULL can be put in place of a variable reference, which
-  means the corresponding captured argument(s) should be just dropped.
-
-  The number of given arguments, excluding an option hash or iterator
-  block, is returned.
-
-int rb_get_kwargs(VALUE keyword_hash, const ID *table, int required, int optional, VALUE *values)
-
-  Retrieves argument VALUEs bound to keywords, which directed by +table+
-  into +values+.  First +required+ number of IDs referred by +table+ are
-  mandatory, and succeeding +optional+ (- +optional+ - 1 if
-  +optional+ is negative) number of IDs are optional.  If a
-  mandatory key is not contained in +keyword_hash+, raises "missing
-  keyword" +ArgumentError+.  If an optional key is not present in
-  +keyword_hash+, the corresponding element in +values+ is not changed.
-  If +optional+ is negative, rest of +keyword_hash+ are stored in the
-  next to optional +values+ as a new Hash, otherwise raises "unknown
-  keyword" +ArgumentError+.
-
-VALUE rb_extract_keywords(VALUE *original_hash)
-
-  Extracts pairs whose key is a symbol into a new hash from a hash
-  object referred by +original_hash+.  If the original hash contains
-  non-symbol keys, then they are copied to another hash and the new hash
-  is stored through +original_hash+, else 0 is stored.

+process.  Otherwise, mark should be 0.  When this object is no longer
+referred by anywhere, the pointer will be discarded by free function.
 
-VALUE rb_block_call(VALUE recv, ID mid, int argc, VALUE * argv, VALUE (*func) (ANYARGS), VALUE data2) ::
+ Data_Make_Struct(klass, type, mark, free, sval)
 
-  Calls a method on the recv, with the method name specified by the
-  symbol mid, with argc arguments in argv, supplying func as the
-  block. When func is called as the block, it will receive the value
-  from yield as the first argument, and data2 as the second argument.
-  When yielded with multiple values (in C, rb_yield_values(),
-  rb_yield_values2() and rb_yield_splat()), data2 is packed as an Array,
-  whereas yielded values can be gotten via argc/argv of the third/fourth
-  arguments.

+ Data_Get_Struct(data, type, sval)
 
-  Calls the function func1, supplying func2 as the block.  func1 will be
-  called with the argument arg1.  func2 receives the value from yield as
-  the first argument, arg2 as the second argument.
+This macro retrieves the pointer value from DATA, and assigns it to
+the variable sval. 
 
-  When rb_iterate is used in 1.9, func1 has to call some Ruby-level method.
-  This function is obsolete since 1.9; use rb_block_call instead.
+** defining class/module
 
-VALUE rb_yield(VALUE val) ::
+ VALUE rb_define_class(const char *name, VALUE super)
 
-  Evaluates the block with value val.
+Defines new Ruby class as subclass of super.

+ VALUE rb_define_class_under(VALUE module, const char *name, VALUE super)
 
-  Calls the function func1, with arg1 as the argument.  If an exception
-  occurs during func1, it calls func2 with arg2 as the argument.  The
-  return value of rb_rescue() is the return value from func1 if no
-  exception occurs, from func2 otherwise.
+Creates new Ruby class as subclass of super, under the module's
+namespace.
 
-VALUE rb_ensure(VALUE (*func1)(), VALUE arg1, VALUE (*func2)(), VALUE arg2) ::
+ VALUE rb_define_module(const char *name)
 
-  Calls the function func1 with arg1 as the argument, then calls func2
-  with arg2 if execution terminated.  The return value from
-  rb_ensure() is that of func1 when no exception occurred.
+Defines new Ruby module.
 
-VALUE rb_protect(VALUE (*func) (VALUE), VALUE arg, int *state) ::
+ VALUE rb_define_module_under(VALUE module, const char *name, VALUE super)
 
-  Calls the function func with arg as the argument.  If no exception
-  occurred during func, it returns the result of func and *state is zero.
-  Otherwise, it returns Qnil and sets *state to nonzero.  If state is
-  NULL, it is not set in both cases.
-  You have to clear the error info with rb_set_errinfo(Qnil) when
-  ignoring the caught exception.
+Defines new Ruby module, under the module's namespace.
 
-void rb_jump_tag(int state) ::
+ void rb_include_module(VALUE klass, VALUE module)
 
-  Continues the exception caught by rb_protect() and rb_eval_string_protect().
-  state must be the returned value from those functions.  This function
-  never return to the caller.
+Includes module into class.  If class already includes it, just
+ignore.
 
-void rb_iter_break() ::

+	void setter(VALUE val, ID id)
 
-  Raises RuntimeError.  The fmt is a format string just like printf().
+The getter function must return the value for the access.
 
-void rb_raise(VALUE exception, const char *fmt, ...) ::
+ void rb_define_hooked_variable(const char *name, VALUE *var,
+				VALUE (*getter)(), VALUE (*setter)())
 
-  Raises a class exception.  The fmt is a format string just like printf().
+Defines hooked variable.  It's virtual variable with C variable.  The
+getter is called as
 
-void rb_fatal(const char *fmt, ...) ::
+	VALUE getter(ID id, VALUE *var)
 
-  Raises a fatal error, terminates the interpreter.  No exception handling
-  will be done for fatal errors, but ensure blocks will be executed.
+returning new value.  The setter is called as
 
-void rb_bug(const char *fmt, ...) ::
+	void setter(VALUE val, ID id, VALUE *var)
 
-  Terminates the interpreter immediately.  This function should be
-  called under the situation caused by the bug in the interpreter.  No
-  exception handling nor ensure execution will be done.
+GC requires to mark the C global variables which hold Ruby values.
 
-Note: In the format string, "%"PRIsVALUE can be used for Object#to_s
-(or Object#inspect if '+' flag is set) output (and related argument
-must be a VALUE).  Since it conflicts with "%i", for integers in
-format strings, use "%d".
+ void rb_global_variable(VALUE *var)
 
-== Initialize and Start the Interpreter
+Tells GC to protect these variables.
 
-The embedding API functions are below (not needed for extension libraries):
+** Constant Definition
 
-void ruby_init() ::
+ void rb_define_const(VALUE klass, const char *name, VALUE val)
 
-  Initializes the interpreter.
+Defines a new constant under the class/module.
 
-void *ruby_options(int argc, char **argv) ::
+ void rb_define_global_const(const char *name, VALUE val)
 
-  Process command line arguments for the interpreter.
-  And compiles the Ruby source to execute.
-  It returns an opaque pointer to the compiled source
-  or an internal special value.
+Defines global constant.  This is just work as
 
-int ruby_run_node(void *n) ::
+     rb_define_const(cKernal, name, val)
 
-  Runs the given compiled source and exits this process.
-  It returns EXIT_SUCCESS if successfully runs the source.
-  Otherwise, it returns other value.
+** Method Definition
 
-void ruby_script(char *name) ::
+ rb_define_method(VALUE klass, const char *name, VALUE (*func)(), int argc)
 
-  Specifies the name of the script ($0).
+Defines a method for the class.  func is the function pointer.  argc
+is the number of arguments.  if argc is -1, the function will receive
+3 arguments argc, argv, and self.  if argc is -2, the function will
+receive 2 arguments, self and args, where args is the Ruby array of
+the method arguments.
 
-== Hooks for the Interpreter Events
+ rb_define_private_method(VALUE klass, const char *name, VALUE (*func)(), int argc)
 
-  void rb_add_event_hook(rb_event_hook_func_t func, rb_event_flag_t events,
-                         VALUE data)
+Defines a private method for the class.  Arguments are same as
+rb_define_method().
 
-Adds a hook function for the specified interpreter events.
-events should be OR'ed value of:
+ rb_define_singleton_method(VALUE klass, const char *name, VALUE (*func)(), int argc)
 
-  RUBY_EVENT_LINE
-  RUBY_EVENT_CLASS
-  RUBY_EVENT_END
-  RUBY_EVENT_CALL
-  RUBY_EVENT_RETURN
-  RUBY_EVENT_C_CALL
-  RUBY_EVENT_C_RETURN
-  RUBY_EVENT_RAISE
-  RUBY_EVENT_ALL
+Defines a singleton method.  Arguments are same as rb_define_method().
 
-The definition of rb_event_hook_func_t is below:
+ rb_scan_args(int argc, VALUE *argv, const char *fmt, ...)
 
-  typedef void (*rb_event_hook_func_t)(rb_event_t event, VALUE data,
-                                       VALUE self, ID id, VALUE klass)
+Retrieve argument from argc, argv.  The fmt is the format string for
+the arguments, such as "12" for 1 non-optional argument, 2 optional
+arguments.  If `*' appears at the end of fmt, it means the rest of
+the arguments are assigned to corresponding variable, packed in
+array.
 
-The third argument `data' to rb_add_event_hook() is passed to the hook
-function as the second argument, which was the pointer to the current
-NODE in 1.8.  See RB_EVENT_HOOKS_HAVE_CALLBACK_DATA below.
+** Invoking Ruby method
 
-  int rb_remove_event_hook(rb_event_hook_func_t func)
+ VALUE rb_funcall(VALUE recv, ID mid, int narg, ...)
 
-Removes the specified hook function.
+Invokes the method.  To retrieve mid from method name, use rb_intern().
 
-== Macros for Compatibility
+ VALUE rb_funcall2(VALUE recv, ID mid, int argc, VALUE *argv)
 
-Some macros to check API compatibilities are available by default.
+Invokes method, passing arguments by array of values.
 
-NORETURN_STYLE_NEW ::
+ VALUE rb_eval_string(const char *str)
 
-  Means that NORETURN macro is functional style instead of prefix.
+Compiles and executes the string as Ruby program.
 
-HAVE_RB_DEFINE_ALLOC_FUNC ::
+ ID rb_intern(const char *name)
 
-  Means that function rb_define_alloc_func() is provided, that means the
-  allocation framework is used.  This is same as the result of
-  have_func("rb_define_alloc_func", "ruby.h").
+Returns ID corresponding the name.
 
-HAVE_RB_REG_NEW_STR ::
+ char *rb_id2name(ID id)
 
-  Means that function rb_reg_new_str() is provided, that creates Regexp
-  object from String object.  This is same as the result of
-  have_func("rb_reg_new_str", "ruby.h").
+Returns the name corresponding ID.
 
-HAVE_RB_IO_T ::
+ char *rb_class2name(VALUE klass)
 
-  Means that type rb_io_t is provided.
+Returns the name of the class.
 
-USE_SYMBOL_AS_METHOD_NAME ::
+ int rb_respond_to(VALUE object, ID id)
 
-  Means that Symbols will be returned as method names, e.g.,
-  Module#methods, #singleton_methods and so on.
+Returns true if the object responds to the message specified by id.
 
-HAVE_RUBY_*_H ::
+** Instance Variables
 
-  Defined in ruby.h and means corresponding header is available.  For
-  instance, when HAVE_RUBY_ST_H is defined you should use ruby/st.h not
-  mere st.h.
+ VALUE rb_iv_get(VALUE obj, const char *name)
 
-RB_EVENT_HOOKS_HAVE_CALLBACK_DATA ::
+Retrieve the value of the instance variable.  If the name is not
+prefixed by `@', that variable shall be inaccessible from Ruby.
 
-  Means that rb_add_event_hook() takes the third argument `data', to be
-  passed to the given event hook function.
+ VALUE rb_iv_set(VALUE obj, const char *name, VALUE val)
 
-= Appendix C. Functions available for use in extconf.rb
+Sets the value of the instance variable.
 
-See documentation for {mkmf}[rdoc-ref:MakeMakefile].
+** Control Structure
 
-= Appendix D. Generational GC
+ VALUE rb_iterate(VALUE (*func1)(), void *arg1, VALUE (*func2)(), void *arg2)
 
-Ruby 2.1 introduced a generational garbage collector (called RGenGC).
-RGenGC (mostly) keeps compatibility.
+Calls the function func1, supplying func2 as the block.  func1 will be
+called with the argument arg1.  func2 receives the value from yield as
+the first argument, arg2 as the second argument.
+ 
+ VALUE rb_yield(VALUE val)
 
-Generally, the use of the technique called write barriers is required in
-extension libraries for generational GC
-(http://en.wikipedia.org/wiki/Garbage_collection_%28computer_science%29).
-RGenGC works fine without write barriers in extension libraries.
+Evaluates the block with value val.
 
-If your library adheres to the following tips, performance can
-be further improved. Especially, the "Don't touch pointers directly" section is
-important.
+ VALUE rb_rescue(VALUE (*func1)(), void *arg1, VALUE (*func2)(), void *arg2)
 
-== Incompatibility
+Calls the function func1, with arg1 as the argument.  If exception
+occurs during func1, it calls func2 with arg2 as the argument.  The
+return value of rb_rescue() is the return value from func1 if no
+exception occurs, from func2 otherwise.
 
-You can't write RBASIC(obj)->klass field directly because it is const
-value now.
+ VALUE rb_ensure(VALUE (*func1)(), void *arg1, void (*func2)(), void *arg2)
 
-Basically you should not write this field because MRI expects it to be
-an immutable field, but if you want to do it in your extension you can
-use the following functions:
+Calls the function func1 with arg1 as the argument, then calls func2
+with arg2, whenever execution terminated.  The return value from
+rb_ensure() is that of func1.
 
-VALUE rb_obj_hide(VALUE obj) ::
+** Exceptions and Errors
 
-  Clear RBasic::klass field. The object will be an internal object.
-  ObjectSpace::each_object can't find this object.
+ void rb_warn(const char *fmt, ...)
 
-VALUE rb_obj_reveal(VALUE obj, VALUE klass) ::
+Prints warning message according to the printf-like format.
 
-  Reset RBasic::klass to be klass.
-  We expect the `klass' is hidden class by rb_obj_hide().
+ void rb_warning(const char *fmt, ...)
 
-== Write barriers
+Prints warning message according to the printf-like format, if
+$VERBOSE is true.
 
-RGenGC doesn't require write barriers to support generational GC.
-However, caring about write barrier can improve the performance of
-RGenGC. Please check the following tips.
+ void rb_raise(VALUE exception, const char *fmt, ...)
 
-=== Don't touch pointers directly
+Raises an exception of class exception.  The fmt is the format string
+just like printf().
 
-In MRI (include/ruby/ruby.h), some macros to acquire pointers to the
-internal data structures are supported such as RARRAY_PTR(),
-RSTRUCT_PTR() and so on.
+ void rb_fatal(const char *fmt, ...)
 
-DO NOT USE THESE MACROS and instead use the corresponding C-APIs such as
-rb_ary_aref(), rb_ary_store() and so on.
+Raises fatal error, terminates the interpreter.  No exception handling
+will be done for fatal error, but ensure blocks will be executed.
 
-=== Consider whether to insert write barriers
+ void rb_bug(const char *fmt, ...)
 
-You don't need to care about write barriers if you only use built-in
-types.
+Terminates the interpreter immediately.  This function should be
+called under the situation caused by the bug in the interpreter.  No
+exception handling nor ensure execution will be done.
 
-If you support T_DATA objects, you may consider using write barriers.
+** Initialize and Starts the Interpreter
 
-Inserting write barriers into T_DATA objects only works with the
-following type objects: (a) long-lived objects, (b) when a huge number
-of objects are generated and (c) container-type objects that have
-references to other objects. If your extension provides such a type of
-T_DATA objects, consider inserting write barriers.
+The embedding API are below (not needed for extension libraries):
 
-(a): short-lived objects don't become old generation objects.
-(b): only a few oldgen objects don't have performance impact.
-(c): only a few references don't have performance impact.
+ void ruby_init()
 
-Inserting write barriers is a very difficult hack, it is easy to
-introduce critical bugs. And inserting write barriers has several areas
-of overhead. Basically we don't recommend you insert write barriers.
-Please carefully consider the risks.
+Initializes the interpreter.
 
-=== Combine with built-in types
+ void ruby_options(int argc, char **argv)
 
-Please consider utilizing built-in types. Most built-in types support
-write barrier, so you can use them to avoid manually inserting write
-barriers.
+Process command line arguments for the interpreter.
 
-For example, if your T_DATA has references to other objects, then you
-can move these references to Array. A T_DATA object only has a reference
-to an array object. Or you can also use a Struct object to gather a
-T_DATA object (without any references) and an that Array contains
-references.
+ void ruby_run()
 
-With use of such techniques, you don't need to insert write barriers
-anymore.
+Starts execution of the interpreter.
 
-=== Insert write barriers
+ void ruby_script(char *name)
 
-[AGAIN] Inserting write barriers is a very difficult hack, and it is
-easy to introduce critical bugs. And inserting write barriers has
-several areas of overhead. Basically we don't recommend you insert write
-barriers. Please carefully consider the risks.
+Specifies the name of the script ($0).
 
-Before inserting write barriers, you need to know about RGenGC algorithm
-(gc.c will help you). Macros and functions to insert write barriers are
-available in in include/ruby/ruby.h. An example is available in iseq.c.
+Appendix B. Functions Available in extconf.rb
 
-For a complete guide for RGenGC and write barriers, please refer to
-<https://bugs.ruby-lang.org/projects/ruby-trunk/wiki/RGenGC>.
+These functions are available in extconf.rb:
 
-= Appendix E. RB_GC_GUARD to protect from premature GC
+ have_library(lib, func)
 
-C Ruby currently uses conservative garbage collection, thus VALUE
-variables must remain visible on the stack or registers to ensure any
-associated data remains usable.  Optimizing C compilers are not designed
-with conservative garbage collection in mind, so they may optimize away
-the original VALUE even if the code depends on data associated with that
-VALUE.
+Checks whether library which contains specified function exists.
+Returns true if the library exists.
 
-The following example illustrates the use of RB_GC_GUARD to ensure
-the contents of sptr remain valid while the second invocation of
-rb_str_new_cstr is running.
+ find_library(lib, func, path...)
 
-  VALUE s, w;
-  const char *sptr;
+Checks whether library which contains specified function exists in
+path.  Returns true if the library exists.
 
-  s = rb_str_new_cstr("hello world!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!");
-  sptr = RSTRING_PTR(s);
-  w = rb_str_new_cstr(sptr + 6); /* Possible GC invocation */
+ have_func(func, header)
 
-  RB_GC_GUARD(s); /* ensure s (and thus sptr) do not get GC-ed */
+Checks whether func exists with header.  Returns true if the function
+exists.  To check functions in the additional library, you need to
+check that library first using have_library().
 
-In the above example, RB_GC_GUARD must be placed _after_ the last use of
-sptr.  Placing RB_GC_GUARD before dereferencing sptr would be of no use.
-RB_GC_GUARD is only effective on the VALUE data type, not converted C
-data types.
+ have_header(header)
 
-RB_GC_GUARD would not be necessary at all in the above example if
-non-inlined function calls are made on the `s' VALUE after sptr is
-dereferenced.  Thus, in the above example, calling any un-inlined
-function on `s' such as:
+Checks whether header exists.  Returns true if the header file exists.
 
-  rb_str_modify(s);
+ create_makefile(target)
 
-Will ensure `s' stays on the stack or register to prevent a
-GC invocation from prematurely freeing it.
+Generates the Makefile for the extension library.  If you don't invoke
+this method, the compilation will not be done.
 
-Using the RB_GC_GUARD macro is preferable to using the "volatile"
-keyword in C.  RB_GC_GUARD has the following advantages:
+ with_config(withval[, default=nil])
 
-1) the intent of the macro use is clear
+Parses the command line options and returns the value specified by
+--with-<withval>.
 
-2) RB_GC_GUARD only affects its call site, "volatile" generates some
-   extra code every time the variable is used, hurting optimization.
+ dir_config(target[, default_dir])
+ dir_config(target[, default_include, default_lib])
 
-3) "volatile" implementations may be buggy/inconsistent in some
-   compilers and architectures. RB_GC_GUARD is customizable for broken
-   systems/compilers without those without negatively affecting other
-   systems.
+Parses the command line options and adds the directories specified by
+--with-<target>-dir, --with-<target>-include, and/or --with-<target>-lib
+to $CFLAGS and/or $LDFLAGS.  --with-<target>-dir=/path is equivalent to
+--with-<target>-include=/path/include --with-<target>-lib=/path/lib.
+Returns an array of the added directories ([include_dir, lib_dir]).

-Rubyの拡張ライブラリの作り方を説明します．
-
-= 基礎知識
-
-Cの変数には型があり，データには型がありません．ですから，た
-とえばポインタをintの変数に代入すると，その値は整数として取
-り扱われます．逆にRubyの変数には型がなく，データに型がありま
-す．この違いのため，CとRubyは相互に変換しなければ，お互いの
-データをアクセスできません．
-
-RubyのデータはVALUEというCの型で表現されます．VALUE型のデー
-タはそのデータタイプを自分で知っています．このデータタイプと
-いうのはデータ(オブジェクト)の実際の構造を意味していて，Ruby
-のクラスとはまた違ったものです．
-
-VALUEからCにとって意味のあるデータを取り出すためには
-
-1. VALUEのデータタイプを知る
-2. VALUEをCのデータに変換する
-
-の両方が必要です．(1)を忘れると間違ったデータの変換が行われ
-て，最悪プログラムがcore dumpします．
-
-== データタイプ
-
-Rubyにはユーザが使う可能性のある以下のタイプがあります．
-
-T_NIL      :: nil
-T_OBJECT   :: 通常のオブジェクト
-T_CLASS    :: クラス
-T_MODULE   :: モジュール
-T_FLOAT    :: 浮動小数点数
-T_STRING   :: 文字列
-T_REGEXP   :: 正規表現
-T_ARRAY    :: 配列
-T_HASH     :: 連想配列
-T_STRUCT   :: (Rubyの)構造体
-T_BIGNUM   :: 多倍長整数
-T_FIXNUM   :: Fixnum(31bitまたは63bit長整数)
-T_COMPLEX  :: 複素数
-T_RATIONAL :: 有理数
-T_FILE     :: 入出力
-T_TRUE     :: 真
-T_FALSE    :: 偽
-T_DATA     :: データ
-T_SYMBOL   :: シンボル
-
-その他に内部で利用されている以下のタイプがあります．
-
-  T_ICLASS
-  T_MATCH
-  T_UNDEF
-  T_NODE
-  T_ZOMBIE
-
-ほとんどのタイプはCの構造体で実装されています．
-
-== VALUEのデータタイプをチェックする
-
-ruby.hではTYPE()というマクロが定義されていて，VALUEのデータ
-タイプを知ることが出来ます．TYPE()マクロは上で紹介したT_XXXX
-の形式の定数を返します．VALUEのデータタイプに応じて処理する
-場合には，TYPE()の値で分岐することになります．
-
-  switch (TYPE(obj)) {
-    case T_FIXNUM:
-      /* FIXNUMの処理 */
-      break;
-    case T_STRING:
-      /* 文字列の処理 */
-      break;
-    case T_ARRAY:
-      /* 配列の処理 */
-      break;
-    default:
-      /* 例外を発生させる */
-      rb_raise(rb_eTypeError, "not valid value");
-      break;
-  }
-
-それとデータタイプをチェックして，正しくなければ例外を発生す
-る関数が用意されています．
-
-  void Check_Type(VALUE value, int type)
-
-この関数はvalueがtypeで無ければ，例外を発生させます．引数と
-して与えられたVALUEのデータタイプが正しいかどうかチェックす
-るためには，この関数を使います．
-
-FIXNUMとNILに関してはより高速な判別マクロが用意されています．
-
-  FIXNUM_P(obj)
-  NIL_P(obj)
-
-== VALUEをCのデータに変換する
-
-データタイプがT_NIL，T_FALSE，T_TRUEである時，データはそれぞ
-れnil，false，trueです．このデータタイプのオブジェクトはひと
-つずつしか存在しません．
-
-データタイプがT_FIXNUMの時，これは31bitまたは63bitのサイズを
-持つ整数です．longのサイズが32bitのプラットフォームであれば
-31bitに，longのサイズが64bitのプラットフォームであれば63bit
-になります. FIXNUM を C の整数に変換するためにはマクロ
-「FIX2INT()」または「FIX2LONG()」を使います．これらのマクロ
-を使用する際には事前にデータタイプがFIXNUMであることを確認す
-る必要がありますが，比較的高速に変換を行うことができます．ま
-た，「FIX2LONG()」は例外を発生しませんが，「FIX2INT()」は変
-換結果がintのサイズに収まらない場合には例外を発生します．
-それから，FIXNUMに限らずRubyのデータを整数に変換する
-「NUM2INT()」および「NUM2LONG()」というマクロがあります．こ
-れらのマクロはデータタイプのチェック無しで使えます
-(整数に変換できない場合には例外が発生する)．同様にチェック無し
-で使える変換マクロはdoubleを取り出す「NUM2DBL()」があります．
-
-char* を取り出す場合， StringValue() と StringValuePtr()
-を使います．
-StringValue(var) は var が String
-であれば何もせず，そうでなければ var を var.to_str() の結果
-に置き換えるマクロ，StringValuePtr(var) は同様に var を
-String に置き換えてから var のバイト列表現に対する char* を
-返すマクロです．var の内容を直接置き換える処理が入るので，
-var は lvalue である必要があります．
-また，StringValuePtr() に類似した StringValueCStr() というマ
-クロもあります．StringValueCStr(var) は var を String に置き
-換えてから var の文字列表現に対する char* を返します．返され
-る文字列の末尾には NUL 文字が付加されます．なお，途中に NUL
-文字が含まれる場合は ArgumentError が発生します．
-一方，StringValuePtr() では，末尾に NUL 文字がある保証はなく，
-途中に NUL 文字が含まれている可能性もあります．
-
-それ以外のデータタイプは対応するCの構造体があります．対応す
-る構造体のあるVALUEはそのままキャスト(型変換)すれば構造体の
-ポインタに変換できます．
-
-構造体は「struct RXxxxx」という名前でruby.hで定義されていま
-す．例えば文字列は「struct RString」です．実際に使う可能性が
-あるのは文字列と配列くらいだと思います．
-
-ruby.hでは構造体へキャストするマクロも「RXXXXX()」(全部大文
-字にしたもの)という名前で提供されています(例: RSTRING())．た
-だし、構造体への直接のアクセスはできるだけ避け，対応する
-rb_xxxx() といった関数を使うようにして下さい．例えば，配列の
-要素へアクセスする場合は，rb_ary_entry(ary, offset)，
-rb_ary_store(ary, offset, obj) を利用するようにして下さい．
-
-構造体からデータを取り出すマクロが提供されています．文字列
-strの長さを得るためには「RSTRING_LEN(str)」とし，文字列strを
-char*として得るためには「RSTRING_PTR(str)」とします．
-
-Rubyの構造体を直接アクセスする時に気をつけなければならないこ
-とは，配列や文字列の構造体の中身は参照するだけで，直接変更し
-ないことです．直接変更した場合，オブジェクトの内容の整合性が
-とれなくなって，思わぬバグの原因になります．
-
-== CのデータをVALUEに変換する
-
-VALUEの実際の構造は
-
-FIXNUMの場合 ::
-
-  1bit左シフトして，LSBを立てる．
-
-その他のポインタの場合 ::
-
-  そのままVALUEにキャストする．
-
-となっています．よって，LSBをチェックすればVALUEがFIXNUMかど
-うかわかるわけです(ポインタのLSBが立っていないことを仮定して
-いる)．
-
-ですから，FIXNUM以外のRubyのオブジェクトの構造体は単にVALUE
-にキャストするだけでVALUEに変換出来ます．ただし，任意の構造
-体がVALUEにキャスト出来るわけではありません．キャストするの
-はRubyの知っている構造体(ruby.hで定義されているstruct RXxxx
-のもの)だけです．
-
-FIXNUMに関しては変換マクロを経由する必要があります．Cの整数
-からVALUEに変換するマクロは以下のものがあります．必要に応じ
-て使い分けてください．
-
-INT2FIX() :: もとの整数が31bitまたは63bit以内に収まる自信
-      	     がある時
-INT2NUM() :: 任意の整数からVALUEへ
-
-INT2NUM()は整数がFIXNUMの範囲に収まらない場合，Bignumに変換
-してくれます(が，少し遅い)．
-
-== Rubyのデータを操作する
-
-先程も述べた通り，Rubyの構造体をアクセスする時に内容の更新を
-行うことは勧められません．で，Rubyのデータを操作する時には
-Rubyが用意している関数を用いてください．
-
-ここではもっとも使われるであろう文字列と配列の生成/操作を行
-う関数をあげます(全部ではないです)．
-
-=== 文字列に対する関数
-
-rb_str_new(const char *ptr, long len) ::
-
-  新しいRubyの文字列を生成する．
-
-rb_str_new2(const char *ptr)
-rb_str_new_cstr(const char *ptr)
-
-  Cの文字列からRubyの文字列を生成する．この関数の機能は
-  rb_str_new(ptr, strlen(ptr))と同等である．
-
-rb_str_new_literal(const char *ptr)
-
-  Cのリテラル文字列からRubyの文字列を生成する．
-
-rb_tainted_str_new(const char *ptr, long len)
-
-  汚染マークが付加された新しいRubyの文字列を生成する．外部
-  からのデータに基づく文字列には汚染マークが付加されるべき
-  である．
-
-rb_tainted_str_new2(const char *ptr)
-rb_tainted_str_new_cstr(const char *ptr)
-
-  Cの文字列から汚染マークが付加されたRubyの文字列を生成する．
-
-rb_sprintf(const char *format, ...)
-rb_vsprintf(const char *format, va_list ap)
-
-  Cの文字列formatと続く引数をprintf(3)のフォーマットにしたがって
-  整形し，Rubyの文字列を生成する．
-
-  注意: "%"PRIsVALUEがObject#to_s('+'フラグが指定されている
-  ときはObject#inspect)を使ったVALUEの出力に利用できる．これ
-  は"%i"と衝突するため，整数には"%d"を使用すること．
-
-rb_str_cat(VALUE str, const char *ptr, long len)
-
-  Rubyの文字列strにlenバイトの文字列ptrを追加する．
-
-rb_str_cat2(VALUE str, const char* ptr)
-rb_str_cat_cstr(VALUE str, const char* ptr)
-
-  Rubyの文字列strにCの文字列ptrを追加する．この関数の機能は
-  rb_str_cat(str, ptr, strlen(ptr))と同等である．
-
-rb_str_catf(VALUE str, const char* format, ...)
-rb_str_vcatf(VALUE str, const char* format, va_list ap)
-

-= Rubyの機能を使う
-
-原理的にRubyで書けることはCでも書けます．RubyそのものがCで記
-述されているんですから，当然といえば当然なんですけど．ここで
-はRubyの拡張に使うことが多いだろうと予測される機能を中心に紹
-介します．
-
-== Rubyに機能を追加する
-
-Rubyで提供されている関数を使えばRubyインタプリタに新しい機能
-を追加することができます．Rubyでは以下の機能を追加する関数が
-提供されています．
-
-* クラス，モジュール
-* メソッド，特異メソッドなど
-* 定数
-
-では順に紹介します．
-
-=== クラス/モジュール定義
-
-クラスやモジュールを定義するためには，以下の関数を使います．
-
-  VALUE rb_define_class(const char *name, VALUE super)
-  VALUE rb_define_module(const char *name)
-
-これらの関数は新しく定義されたクラスやモジュールを返します．
-メソッドや定数の定義にこれらの値が必要なので，ほとんどの場合
-は戻り値を変数に格納しておく必要があるでしょう．
-
-クラスやモジュールを他のクラスの内部にネストして定義する時に
-は以下の関数を使います．
-
-  VALUE rb_define_class_under(VALUE outer, const char *name, VALUE super)
-  VALUE rb_define_module_under(VALUE outer, const char *name)
-
-=== メソッド/特異メソッド定義
-
-メソッドや特異メソッドを定義するには以下の関数を使います．
-
-  void rb_define_method(VALUE klass, const char *name,
-                        VALUE (*func)(), int argc)
-
-  void rb_define_singleton_method(VALUE object, const char *name,
-                                  VALUE (*func)(), int argc)
-
-
-念のため説明すると「特異メソッド」とは，その特定のオブジェク
-トに対してだけ有効なメソッドです．RubyではよくSmalltalkにお
-けるクラスメソッドとして，クラスに対する特異メソッドが使われ
-ます．
-
-これらの関数の argcという引数はCの関数へ渡される引数の数(と
-形式)を決めます．argcが0以上の時は関数に引き渡す引数の数を意
-味します．16個以上の引数は使えません(が，要りませんよね，そ
-んなに)．実際の関数には先頭の引数としてselfが与えられますの
-で，指定した数より1多い引数を持つことになります．
-
-argcが負の時は引数の数ではなく，形式を指定したことになります．
-argcが-1の時は引数を配列に入れて渡されます．argcが-2の時は引
-数はRubyの配列として渡されます．
-
-メソッドを定義する関数はまだいくつかあります. ひとつはメソッド
-名としてIDを取ります. IDについては2.2.2を参照.
-
-  void rb_define_method_id(VALUE klass, ID name,
-                           VALUE (*func)(ANYARGS), int argc)
-
-private/protectedなメソッドを定義するふたつの関数があります.
-
-  void rb_define_private_method(VALUE klass, const char *name,
-				VALUE (*func)(), int argc)
-  void rb_define_protected_method(VALUE klass, const char *name,
-			          VALUE (*func)(), int argc)
-
-privateメソッドとは関数形式でしか呼び出すことの出来ないメソッ
-ドです．
-
-最後に， rb_define_module関数はモジュール関数を定義します．
-モジュール関数とはモジュールの特異メソッドであり，同時に
-privateメソッドでもあるものです．例をあげるとMathモジュール
-のsqrt()などがあげられます．このメソッドは
-
-  Math.sqrt(4)
-
-という形式でも
-
-  include Math
-  sqrt(4)
-
-という形式でも使えます．モジュール関数を定義する関数は以下の
-通りです．
-
-  void rb_define_module_function(VALUE module, const char *name,
-		                 VALUE (*func)(), int argc)
-
-関数的メソッド(Kernelモジュールのprivate method)を定義するた
-めの関数は以下の通りです．
-
-  void rb_define_global_function(const char *name, VALUE (*func)(), int argc)
-
-
-メソッドの別名を定義するための関数は以下の通りです．
-
-  void rb_define_alias(VALUE module, const char* new, const char* old);
-
-属性の取得・設定メソッドを定義するには
-
-  void rb_define_attr(VALUE klass, const char *name, int read, int write)
-
-クラスメソッドallocateを定義したり削除したりするための関数は
-以下の通りです．
-
-  void rb_define_alloc_func(VALUE klass, VALUE (*func)(VALUE klass));
-  void rb_undef_alloc_func(VALUE klass);
-
-funcはクラスを引数として受け取って，新しく割り当てられたイン
-スタンスを返さなくてはなりません．このインスタンスは，外部リ
-ソースなどを含まない，できるだけ「空」のままにしておいたほう
-がよいでしょう．
-
-継承したクラスにある既存のメソッドをオーバーライドしているな
-ら，オーバーライドされたメソッドを呼び出すには以下の関数を使
-います．
-
-  VALUE rb_call_super(int argc, const VALUE *argv)
-
-現在のスコープのレシーバは(他に方法がなければ)，以下の関数で
-得ることができます．
-
-  VALUE rb_current_receiver(void)
-
-=== 定数定義
-
-拡張ライブラリが必要な定数はあらかじめ定義しておいた方が良い
-でしょう．定数を定義する関数は二つあります．
-
-  void rb_define_const(VALUE klass, const char *name, VALUE val)
-  void rb_define_global_const(const char *name, VALUE val)
-
-前者は特定のクラス/モジュールに属する定数を定義するもの，後
-者はグローバルな定数を定義するものです．
-
-== Rubyの機能をCから呼び出す
-
-既に『1.5 Rubyのデータを操作する』で一部紹介したような関数を
-使えば，Rubyの機能を実現している関数を直接呼び出すことが出来
-ます．
-
-# このような関数の一覧表はいまのところありません．ソースを見
-# るしかないですね．
-
-それ以外にもRubyの機能を呼び出す方法はいくつかあります．
-
-=== Rubyのプログラムをevalする
-
-CからRubyの機能を呼び出すもっとも簡単な方法として，文字列で
-与えられたRubyのプログラムを評価する以下の関数があります．
-
-  VALUE rb_eval_string(const char *str)
-
-この評価は現在の環境で行われます．つまり，現在のローカル変数
-などを受け継ぎます．
-
-評価は例外を発生するかもしれないことに注意しましょう. より安全
-な関数もあります.
-
-  VALUE rb_eval_string_protect(const char *str, int *state)
-
-この関数はエラーが発生するとnilを返します．そして，成功時には
-*stateはゼロに，さもなくば非ゼロになります．
-
-=== IDまたはシンボル
-
-Cから文字列を経由せずにRubyのメソッドを呼び出すこともできま
-す．その前に，Rubyインタプリタ内でメソッドや変数名を指定する
-時に使われているIDについて説明しておきましょう．
-
-IDとは変数名，メソッド名を表す整数です．Rubyの中では
-
- :識別子
-
-または
-
- :"任意の文字列"
-
-でアクセスできます．Cからこの整数を得るためには関数
-
-  rb_intern(const char *name)
-  rb_intern_str(VALUE name)
-
-を使います．Rubyから引数として与えられたシンボル(または文字
-列)をIDに変換するには以下の関数を使います．
-
-  rb_to_id(VALUE symbol)
-  rb_check_id(volatile VALUE *name)
-  rb_check_id_cstr(const char *name, long len, rb_encoding *enc)
-
-もし引数がシンボルでも文字列でもなければ，to_strメソッドで文
-字列に変換しようとします．第二の関数はその変換結果を*nameに保
-存し,その名前が既知のシンボルでない場合は0を返します．この関
-数が0以外を返した場合は*nameは常にシンボルか文字列であり，0を
-返した場合は常に文字列です．第三の関数はRubyの文字列ではなく
-NUL終端されたCの文字列を使います．
-
-Rubyから引数として与えられたシンボル(または文字列)をシンボル
-に変換するには以下の関数を使います．
-
-  rb_to_symbol(VALUE name)
-  rb_check_symbol(volatile VALUE *namep)
-  rb_check_symbol_cstr(const char *ptr, long len, rb_encoding *enc)
-
-これらの関数は，IDの代わりにシンボルを返すことを除けば上記の
-関数と同じです．
-
-=== CからRubyのメソッドを呼び出す
-
-Cから文字列を経由せずにRubyのメソッドを呼び出すためには以下
-の関数を使います．
-
-  VALUE rb_funcall(VALUE recv, ID mid, int argc, ...)
-
-この関数はオブジェクトrecvのmidで指定されるメソッドを呼び出
-します．その他に引数の指定の仕方が違う以下の関数もあります．
-
-  VALUE rb_funcall2(VALUE recv, ID mid, int argc, VALUE *argv)
-  VALUE rb_funcallv(VALUE recv, ID mid, int argc, VALUE *argv)
-  VALUE rb_apply(VALUE recv, ID mid, VALUE args)
-
-applyには引数としてRubyの配列を与えます．
-
-=== 変数/定数を参照/更新する
-
-Cから関数を使って参照・更新できるのは，定数，インスタンス変
-数です．大域変数は一部のものはCの大域変数としてアクセスでき
-ます．ローカル変数を参照する方法は公開していません．
-
-オブジェクトのインスタンス変数を参照・更新する関数は以下の通
-りです．
-
-  VALUE rb_ivar_get(VALUE obj, ID id)
-  VALUE rb_ivar_set(VALUE obj, ID id, VALUE val)
-
-idはrb_intern()で得られるものを使ってください．
-
-定数を参照するには以下の関数を使ってください．
-
-  VALUE rb_const_get(VALUE obj, ID id)
-
-定数を新しく定義するためには『2.1.3 定数定義』で紹介さ
-れている関数を使ってください．
-
-= RubyとCとの情報共有
-
-C言語とRubyの間で情報を共有する方法について解説します．
-
-== Cから参照できるRubyの定数
-
-以下のRubyの定数はCのレベルから参照できます．
-
-  Qtrue
-  Qfalse
-
-真偽値．QfalseはC言語でも偽とみなされます(つまり0)．
-
-  Qnil
-
-C言語から見た「nil」．
-
-== CとRubyで共有される大域変数
-
-CとRubyで大域変数を使って情報を共有できます．共有できる大域
-変数にはいくつかの種類があります．そのなかでもっとも良く使わ
-れると思われるのはrb_define_variable()です．
-
-  void rb_define_variable(const char *name, VALUE *var)
-
-この関数はRubyとCとで共有する大域変数を定義します．変数名が
-`$'で始まらない時には自動的に追加されます．この変数の値を変
-更すると自動的にRubyの対応する変数の値も変わります．
-
-またRuby側からは更新できない変数もあります．このread onlyの
-変数は以下の関数で定義します．
-
-  void rb_define_readonly_variable(const char *name, VALUE *var)
-
-これら変数の他にhookをつけた大域変数を定義できます．hook付き
-の大域変数は以下の関数を用いて定義します．hook付き大域変数の
-値の参照や設定はhookで行う必要があります．
-
-  void rb_define_hooked_variable(const char *name, VALUE *var,
-				 VALUE (*getter)(), void (*setter)())
-
-この関数はCの関数によってhookのつけられた大域変数を定義しま
-す．変数が参照された時には関数getterが，変数に値がセットされ
-た時には関数setterが呼ばれる．hookを指定しない場合はgetterや
-setterに0を指定します．
-# getterもsetterも0ならばrb_define_variable()と同じになる．
-
-getterとsetterの仕様は次の通りです．
-
-  VALUE (*getter)(ID id, VALUE *var);
-  void (*setter)(VALUE val, ID id, VALUE *var);
-
-
-それから，対応するCの変数を持たないRubyの大域変数を定義する
-こともできます. その変数の値はフック関数のみによって取得・設定
-されます.
-
-  void rb_define_virtual_variable(const char *name,
-				  VALUE (*getter)(), void (*setter)())
-
-この関数によって定義されたRubyの大域変数が参照された時には
-getterが，変数に値がセットされた時にはsetterが呼ばれます．
-
-getterとsetterの仕様は以下の通りです．
-
-  (*getter)(ID id);
-  (*setter)(VALUE val, ID id);
-
-== CのデータをRubyオブジェクトにする
-
-Cの世界で定義されたデータ(構造体)をRubyのオブジェクトとして
-取り扱いたい場合がありえます．このような場合には，Dataという
-RubyオブジェクトにCの構造体(へのポインタ)をくるむことでRuby
-オブジェクトとして取り扱えるようになります．
-
-Dataオブジェクトを生成して構造体をRubyオブジェクトにカプセル
-化するためには，以下のマクロを使います．
-
-  Data_Wrap_Struct(klass, mark, free, sval)
-
-このマクロの戻り値は生成されたDataオブジェクトです．
-
-klassはこのDataオブジェクトのクラスです．markはこの構造体が
-Rubyのオブジェクトへの参照がある時に使う関数です．そのような
-参照を含まない時には0を指定します．
-
-# そのような参照は勧められません．
-
-freeはこの構造体がもう不要になった時に呼ばれる関数です．この
-関数がガーベージコレクタから呼ばれます．これが-1の場合は，単
-純に開放されます．
-
-markおよびfree関数はGC実行中に呼び出されます.
-なお, GC実行中はRubyオブジェクトのアロケーションは禁止されま
-す. よって, markおよびfree関数でRubyオブジェクトのアロケーシ
-ョンは行わないでください.
-
-Cの構造体の割当とDataオブジェクトの生成を同時に行うマクロと
-して以下のものが提供されています．
-
-  Data_Make_Struct(klass, type, mark, free, sval)
-
-このマクロの戻り値は生成されたDataオブジェクトです．このマク
-ロは以下の式のように働きます:
-
-  (sval = ALLOC(type), Data_Wrap_Struct(klass, mark, free, sval))
-
-klass, mark, freeはData_Wrap_Structと同じ働きをします．type
-は割り当てるC構造体の型です．割り当てられた構造体は変数sval
-に代入されます．この変数の型は (type*) である必要があります．
-
-Dataオブジェクトからポインタを取り出すのは以下のマクロを用い
-ます．
-
-  Data_Get_Struct(obj, type, sval)
-
-Cの構造体へのポインタは変数svalに代入されます．
-
-これらのDataの使い方はちょっと分かりにくいので，後で説明する
-例題を参照してください．
-
-= 例題 - dbmパッケージを作る
-
-ここまでの説明でとりあえず拡張ライブラリは作れるはずです．
-Rubyのextディレクトリにすでに含まれているdbmライブラリを例に
-して段階的に説明します．
-
-== ディレクトリを作る
-
-  % mkdir ext/dbm
-
-Ruby 1.1からは任意のディレクトリでダイナミックライブラリを作
-ることができるようになりました．Rubyに静的にリンクする場合に
-はRubyを展開したディレクトリの下，extディレクトリの中に拡張
-ライブラリ用のディレクトリを作る必要があります．名前は適当に
-選んで構いません．
-
-== 設計する
-
-まあ，当然なんですけど，どういう機能を実現するかどうかまず設
-計する必要があります．どんなクラスをつくるか，そのクラスには
-どんなメソッドがあるか，クラスが提供する定数などについて設計
-します．
-
-== Cコードを書く
-
-拡張ライブラリ本体となるC言語のソースを書きます．C言語のソー
-スがひとつの時には「ライブラリ名.c」を選ぶと良いでしょう．C
-言語のソースが複数の場合には逆に「ライブラリ名.c」というファ
-イル名は避ける必要があります．オブジェクトファイルとモジュー
-ル生成時に中間的に生成される「ライブラリ名.o」というファイル
-とが衝突するからです．また，後述する mkmf ライブラリのいくつ
-かの関数がコンパイルを要するテストのために「conftest.c」とい
-うファイル名を使用することに注意してください．ソースファイル
-名として「conftest.c」を使用してはなりません．
-
-Rubyは拡張ライブラリをロードする時に「Init_ライブラリ名」と
-いう関数を自動的に実行します．dbmライブラリの場合「Init_dbm」
-です．この関数の中でクラス，モジュール，メソッド，定数などの
-定義を行います．dbm.cから一部引用します．
-
-  void
-  Init_dbm(void)
-  {
-      /* DBMクラスを定義する */
-      VALUE cDBM = rb_define_class("DBM", rb_cObject);
-      /* DBMはEnumerableモジュールをインクルードする */
-      rb_include_module(cDBM, rb_mEnumerable);
-
-      /* DBMクラスのクラスメソッドopen(): 引数はCの配列で受ける */
-      rb_define_singleton_method(cDBM, "open", fdbm_s_open, -1);
-
-      /* DBMクラスのメソッドclose(): 引数はなし */
-      rb_define_method(cDBM, "close", fdbm_close, 0);
-      /* DBMクラスのメソッド[]: 引数は1個 */
-      rb_define_method(cDBM, "[]", fdbm_fetch, 1);
-
-      /* ... */
-
-      /* DBMデータを格納するインスタンス変数名のためのID */
-      id_dbm = rb_intern("dbm");
-  }
-
-DBMライブラリはdbmのデータと対応するオブジェクトになるはずで
-すから，Cの世界のdbmをRubyの世界に取り込む必要があります．
-
-dbm.cではData_Make_Structを以下のように使っています．
-
-  struct dbmdata {
-      int  di_size;
-      DBM *di_dbm;
-  };
-
-
-  obj = Data_Make_Struct(klass, struct dbmdata, 0, free_dbm, dbmp);
-
-ここではdbmstruct構造体へのポインタをDataにカプセル化してい
-ます．DBM*を直接カプセル化しないのはclose()した時の処理を考
-えてのことです．
-
-Dataオブジェクトからdbmstruct構造体のポインタを取り出すため
-に以下のマクロを使っています．
-
-  #define GetDBM(obj, dbmp) do {\
-      Data_Get_Struct((obj), struct dbmdata, (dbmp));\
-      if ((dbmp) == 0) closed_dbm();\
-      if ((dbmp)->di_dbm == 0) closed_dbm();\
-  } while (0)
-
-ちょっと複雑なマクロですが，要するにdbmdata構造体のポインタ
-の取り出しと，closeされているかどうかのチェックをまとめてい
-るだけです．
-
-DBMクラスにはたくさんメソッドがありますが，分類すると3種類の
-引数の受け方があります．ひとつは引数の数が固定のもので，例と
-してはdeleteメソッドがあります．deleteメソッドを実装している
-fdbm_delete()はこのようになっています．
-
-  static VALUE
-  fdbm_delete(VALUE obj, VALUE keystr)
-  {
-      /* ... */
-  }
-
-引数の数が固定のタイプは第1引数がself，第2引数以降がメソッド
-の引数となります．
-
-引数の数が不定のものはCの配列で受けるものとRubyの配列で受け
-るものとがあります．dbmライブラリの中で，Cの配列で受けるもの
-はDBMのクラスメソッドであるopen()です．これを実装している関
-数fdbm_s_open()はこうなっています．
-
-  static VALUE
-  fdbm_s_open(int argc, VALUE *argv, VALUE klass)
-  {
-      /* ... */
-
-      if (rb_scan_args(argc, argv, "11", &file, &vmode) == 1) {
-  	mode = 0666;		/* default value */
-      }
-
-      /* ... */
-  }
-
-このタイプの関数は第1引数が与えられた引数の数，第2引数が与え
-られた引数の入っている配列になります．selfは第3引数として与
-えられます．
-
-この配列で与えられた引数を解析するための関数がopen()でも使わ
-れているrb_scan_args()です．第3引数に指定したフォーマットに従
-い，第4変数以降に指定したVALUEへの参照に値を代入してくれま
-す．
-
-
-引数をRubyの配列として受け取るメソッドの例には
-Thread#initializeがあります．実装はこうです．
-
-  static VALUE
-  thread_initialize(VALUE thread, VALUE args)
-  {
-      /* ... */
-  }
-
-第1引数はself，第2引数はRubyの配列です．
-
-*注意事項*
-
-Rubyと共有はしないがRubyのオブジェクトを格納する可能性のある
-Cの大域変数は以下の関数を使ってRubyインタプリタに変数の存在
-を教えてあげてください．でないとGCでトラブルを起こします．
-
-  void rb_global_variable(VALUE *var)
-
-== extconf.rbを用意する
-
-Makefileを作る場合の雛型になるextconf.rbというファイルを作り
-ます．extconf.rbはライブラリのコンパイルに必要な条件のチェッ
-クなどを行うことが目的です．まず，
-
-  require 'mkmf'
-
-をextconf.rbの先頭に置きます．extconf.rbの中では以下のRuby関
-数を使うことが出来ます．
-
-  have_library(lib, func): ライブラリの存在チェック
-  have_func(func, header): 関数の存在チェック
-  have_header(header): ヘッダファイルの存在チェック
-  create_makefile(target[, target_prefix]): Makefileの生成
-
-以下の変数を使うことができます．
-
-  $CFLAGS: コンパイル時に追加的に指定するフラグ(-Oなど)
-  $CPPFLAGS: プリプロセッサに追加的に指定するフラグ(-Iや-Dなど)
-  $LDFLAGS: リンク時に追加的に指定するフラグ(-Lなど)
-  $objs: リンクされるオブジェクトファイル名のリスト
-
-オブジェクトファイルのリストは，通常はソースファイルを検索し
-て自動的に生成されますが，makeの途中でソースを生成するような
-場合は明示的に指定する必要があります．
-
-ライブラリをコンパイルする条件が揃わず，そのライブラリをコン
-パイルしない時にはcreate_makefileを呼ばなければMakefileは生
-成されず，コンパイルも行われません．
-
-== dependを用意する
-
-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．
-
-  % gcc -MM *.c > depend
-
-などで作ることが出来ます．あって損は無いでしょう．
-
-== Makefileを生成する
-
-Makefileを実際に生成するためには
-
-  ruby extconf.rb
-
-とします．extconf.rbに require 'mkmf' の行がない場合にはエラー
-になりますので，引数を追加して
-
-  ruby -r mkmf extconf.rb
-
-としてください．
-
-site_ruby ディレクトリでなく，
-vendor_ruby ディレクトリにインストールする場合には
-以下のように --vendor オプションを加えてください．
-
-  ruby extconf.rb --vendor
-
-ディレクトリをext以下に用意した場合にはRuby全体のmakeの時に
-自動的にMakefileが生成されますので，このステップは不要です．
-
-== makeする
-
-動的リンクライブラリを生成する場合にはその場でmakeしてくださ
-い．必要であれば make install でインストールされます．
-
-ext以下にディレクトリを用意した場合は，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してくれます．
-extconf.rbを書き換えるなどしてMakefileの再生成が必要な時はま
-たRubyディレクトリでmakeしてください．
-
-拡張ライブラリはmake installでRubyライブラリのディレクトリの
-下にコピーされます．もし拡張ライブラリと協調して使うRubyで記

-= Appendix D. 世代別GC
-
-Ruby 2.1から世代別GCに対応しました．我々はこれをRGenGCと呼んでいます．
-RGenGCは，過去の拡張ライブラリに（ほぼ）互換性を保つように開発されている
-ため，拡張ライブラリ側の対応はほぼ不要です．
-
-ただし，対応をすることで性能を向上することができる可能性があります．もし
-拡張ライブラリに高い性能が必要である場合は対応を検討して下さい．
-
-とくにRARRAY_PTR()/RHASH_TBL()のようなマクロを用いてポインタに直接アクセ
-スするようなコードは書かないようにして下さい．代わりに，rb_ary_aref(),
-rb_ary_store() などの，適切な API 関数を利用するようにして下さい．
-
-そのほか，対応についての詳細は README.EXT の「Appendix D. Generational
-GC」を参照して下さい．

-# Rubyとは
-
-Rubyはシンプルかつ強力なオブジェクト指向スクリプト言語です． Rubyは純粋なオブジェクト指向言語として設計されているので，
-オブジェクト指向プログラミングを手軽に行う事が出来ます．もちろん普通の手続き型のプログラミングも可能です．
-
-Rubyはテキスト処理関係の能力などに優れ，Perlと同じくらい強力です．さらにシンプルな文法と，
-例外処理やイテレータなどの機構によって，より分かりやすいプログラミングが出来ます．
-
-## Rubyの特長
-
-*   シンプルな文法
-*   普通のオブジェクト指向機能(クラス，メソッドコールなど)
-*   特殊なオブジェクト指向機能(Mixin, 特異メソッドなど)
-*   演算子オーバーロード
-*   例外処理機能
-*   イテレータとクロージャ
-*   ガーベージコレクタ
-*   ダイナミックローディング (アーキテクチャによる)
-*   移植性が高い．多くのUnix-like/POSIX互換プラットフォーム上で動くだけでなく，Windows， Mac OS
-    X，BeOSなどの上でも動く cf.
-    http://bugs.ruby-lang.org/projects/ruby-trunk/wiki/SupportedPlatformsJa

-
-## ホームページ
-
-RubyのホームページのURLは
-
-http://www.ruby-lang.org/
-
-です．
-
-## メーリングリスト
-
-Rubyのメーリングリストがあります。参加希望の方は
-
-mailto:ruby-list-request@ruby-lang.org
-
-まで本文に
-
-    subscribe
-
-と書いて送って下さい。
-
-Ruby開発者向けメーリングリストもあります。こちらではrubyのバグ、将来の仕様拡張など実装上の問題について議論されています。 参加希望の方は
-
-mailto:ruby-dev-request@ruby-lang.org
-
-までruby-listと同様の方法でメールしてください。
-
-Ruby拡張モジュールについて話し合うruby-extメーリングリストと数学関係の話題について話し合うruby-mathメーリングリストと
-英語でrubyについて話し合うruby-talkメーリングリストもあります。参加方法はどれも同じです。
-
-## コンパイル・インストール
-
-以下の手順で行ってください．
-
-1.  もし `configure` ファイルが見つからない、もしくは `configure.in` より古いようなら、 `autoconf` を実行して
-    新しく `configure` を生成する
-
-2.  `configure` を実行して `Makefile` などを生成する
-
-    環境によってはデフォルトのCコンパイラ用オプションが付きます． `configure` オプションで `optflags=..`
-    `warnflags=..` 等で上書きできます．
-
-3.  (必要ならば)`defines.h` を編集する
-
-    多分，必要無いと思います．
-
-4.  (必要ならば)`ext/Setup` に静的にリンクする拡張モジュールを指定する
-
-    `ext/Setup` に記述したモジュールは静的にリンクされます．
-
-    ダイナミックローディングをサポートしていないアーキテクチャでは `Setup` の1行目の「`option nodynamic`」という行のコ
-    メントを外す必要があります．また，このアーキテクチャで拡張モジュールを利用するためには，あらかじめ静的にリンクをしておく必要があります．
-
-5.  `make` を実行してコンパイルする
-
-6.  `make check`でテストを行う．
-
-    「`check succeeded`」と表示されれば成功です．ただしテストに成功しても完璧だと保証されている訳ではありません．
-
-7.  `make install`
-
-    以下のディレクトリを作って，そこにファイルをインストー ルします．
-
-    *   `${DESTDIR}${prefix}/bin`
-    *   `${DESTDIR}${prefix}/include/ruby-${MAJOR}.${MINOR}.${TEENY}`
-    *   `${DESTDIR}${prefix}/include/ruby-${MAJOR}.${MINOR}.${TEENY}/${PLATFOR
-        M}`
-    *   `${DESTDIR}${prefix}/lib`
-    *   `${DESTDIR}${prefix}/lib/ruby`
-    *   `${DESTDIR}${prefix}/lib/ruby/${MAJOR}.${MINOR}.${TEENY}`
-    *   `${DESTDIR}${prefix}/lib/ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}`
-    *   `${DESTDIR}${prefix}/lib/ruby/site_ruby`
-    *   `${DESTDIR}${prefix}/lib/ruby/site_ruby/${MAJOR}.${MINOR}.${TEENY}`
-    *   `${DESTDIR}${prefix}/lib/ruby/site_ruby/${MAJOR}.${MINOR}.${TEENY}/${P
-        LATFORM}`
-    *   `${DESTDIR}${prefix}/lib/ruby/vendor_ruby`
-    *   `${DESTDIR}${prefix}/lib/ruby/vendor_ruby/${MAJOR}.${MINOR}.${TEENY}`
-    *   `${DESTDIR}${prefix}/lib/ruby/vendor_ruby/${MAJOR}.${MINOR}.${TEENY}/$
-        {PLATFORM}`
-    *   `${DESTDIR}${prefix}/lib/ruby/gems/${MAJOR}.${MINOR}.${TEENY}`
-    *   `${DESTDIR}${prefix}/share/man/man1`
-    *   `${DESTDIR}${prefix}/share/ri/${MAJOR}.${MINOR}.${TEENY}/system`
-
-
-    RubyのAPIバージョンが'*x.y.z*'であれば，`${MAJOR}`は
-    '*x*'で，`${MINOR}`は'*y*'，`${TEENY}`は'*z*'です．
-
-    **注意**: APIバージョンの `teeny` は，Rubyプログラムのバージョンとは異なることがあります．
-
-    `root` で作業する必要があるかもしれません．
-
-
-もし，コンパイル時にエラーが発生した場合にはエラーのログとマシン，OSの種類を含むできるだけ詳しいレポートを作者に送って下さると他の方のためにもなります．
-
-## 移植
-
-UNIXであれば `configure` がほとんどの差異を吸収してくれるはずですが，思わぬ見落としがあった場合(ある事が多い)，作者にその
-ことを報告すれば，解決できる可能性があります．
-
-アーキテクチャにもっとも依存するのはGC部です．RubyのGCは対象
-のアーキテクチャが`setjmp()`または`getcontext()`によって全てのレジスタを `jmp_buf` や `ucontext_t`
-に格納することと， `jmp_buf` や `ucontext_t` とスタックが32bitアラインメントされていることを仮定
-しています．特に前者が成立しない場合の対応は非常に困難でしょう． 後者の解決は比較的簡単で， `gc.c` でスタックをマークしている
-部分にアラインメントのバイト数だけずらしてマークするコードを追加するだけで済みます．`defined(_\*mc68000*\_)`で括られてい
-る部分を参考にしてください．
-
-レジスタウィンドウを持つCPUでは，レジスタウィンドウをスタックにフラッシュするアセンブラコードを追加する必要があるかもしれません．
-
-## 配布条件
-
-`COPYING.ja` ファイルを参照してください。
-
-## 著者
-
-コメント，バグレポートその他は mailto:matz@ruby-lang.org まで．

-# What's Ruby
-
-Ruby is the interpreted scripting language for quick and easy object-oriented
-programming.  It has many features to process text files and to do system
-management tasks (as in Perl).  It is simple, straight-forward, and
-extensible.
-
-## Features of Ruby
-
-*   Simple Syntax
-*   **Normal** Object-Oriented features(ex. class, method calls)
-*   **Advanced** Object-Oriented features(ex. Mix-in, Singleton-method)
-*   Operator Overloading
-*   Exception Handling
-*   Iterators and Closures
-*   Garbage Collection
-*   Dynamic Loading of Object files(on some architecture)
-*   Highly Portable (works on many Unix-like/POSIX compatible platforms as
-    well as Windows, Mac OS X, BeOS etc.) cf.
-    http://bugs.ruby-lang.org/projects/ruby-trunk/wiki/SupportedPlatforms
-
-
-## How to get Ruby
-
-For a complete list of ways to install Ruby, including using third party tools
-like rvm, see:
-
-http://www.ruby-lang.org/en/downloads/
-
-The Ruby distribution files can be found in the following FTP site:
-
-ftp://ftp.ruby-lang.org/pub/ruby/
-
-The trunk of the Ruby source tree can be checked out with the following
-command:
-
-    $ svn co http://svn.ruby-lang.org/repos/ruby/trunk/ ruby
-
-Or if you are using git then use the following command:
-
-    $ git clone git://github.com/ruby/ruby.git
-
-There are some other branches under development.  Try the following command
-and see the list of branches:
-
-    $ svn ls http://svn.ruby-lang.org/repos/ruby/branches/
-
-Or if you are using git then use the following command:
-
-    $ git ls-remote git://github.com/ruby/ruby.git
-
-## Ruby home-page
-
-The URL of the Ruby home-page is:
-
-http://www.ruby-lang.org/
-
-## Mailing list
-
-There is a mailing list to talk about Ruby. To subscribe this list, please
-send the following phrase
-
-    subscribe
-
-in the mail body (not subject) to the address
-<mailto:ruby-talk-request@ruby-lang.org>.
-
-## How to compile and install
-
-This is what you need to do to compile and install Ruby:
-
-1.  If you want to use Microsoft Visual C++ to compile ruby, read
-    win32/README.win32 instead of this document.
-
-2.  If `./configure` does not exist or is older than configure.in, run
-    autoconf to (re)generate configure.
-
-3.  Run `./configure`, which will generate config.h and Makefile.
-
-    Some C compiler flags may be added by default depending on your
-    environment.  Specify `optflags=..` and `warnflags=..` as necessary to
-    override them.
-
-4.  Edit `defines.h` if you need. Usually this step will not be needed.
-
-5.  Remove comment mark(`#`) before the module names from `ext/Setup` (or add
-    module names if not present), if you want to link modules statically.
-
-    If you don't want to compile non static extension modules (probably on
-    architectures which do not allow dynamic loading), remove comment mark
-    from the line "`#option nodynamic`" in `ext/Setup`.
-
-    Usually this step will not be needed.
-
-6.  Run `make`.
-
-7.  Optionally, run '`make check`' to check whether the compiled Ruby
-    interpreter works well. If you see the message "`check succeeded`", your
-    ruby works as it should (hopefully).
-
-8.  Run '`make install`'
-
-    This command will create following directories and install files onto
-    them.
-
-    *   `${DESTDIR}${prefix}/bin`
-    *   `${DESTDIR}${prefix}/include/ruby-${MAJOR}.${MINOR}.${TEENY}`
-    *   `${DESTDIR}${prefix}/include/ruby-${MAJOR}.${MINOR}.${TEENY}/${PLATFOR
-        M}`
-    *   `${DESTDIR}${prefix}/lib`
-    *   `${DESTDIR}${prefix}/lib/ruby`
-    *   `${DESTDIR}${prefix}/lib/ruby/${MAJOR}.${MINOR}.${TEENY}`
-    *   `${DESTDIR}${prefix}/lib/ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}`
-    *   `${DESTDIR}${prefix}/lib/ruby/site_ruby`
-    *   `${DESTDIR}${prefix}/lib/ruby/site_ruby/${MAJOR}.${MINOR}.${TEENY}`
-    *   `${DESTDIR}${prefix}/lib/ruby/site_ruby/${MAJOR}.${MINOR}.${TEENY}/${P
-        LATFORM}`
-    *   `${DESTDIR}${prefix}/lib/ruby/vendor_ruby`
-    *   `${DESTDIR}${prefix}/lib/ruby/vendor_ruby/${MAJOR}.${MINOR}.${TEENY}`
-    *   `${DESTDIR}${prefix}/lib/ruby/vendor_ruby/${MAJOR}.${MINOR}.${TEENY}/$
-        {PLATFORM}`
-    *   `${DESTDIR}${prefix}/lib/ruby/gems/${MAJOR}.${MINOR}.${TEENY}`
-    *   `${DESTDIR}${prefix}/share/man/man1`
-    *   `${DESTDIR}${prefix}/share/ri/${MAJOR}.${MINOR}.${TEENY}/system`
-
-
-    If Ruby's API version is '*x.y.z*', the `${MAJOR}` is '*x*', the
-    `${MINOR}` is '*y*', and the `${TEENY}` is '*z*'.
-
-    **NOTE**: teeny of the API version may be different from one of Ruby's
-    program version
-
-    You may have to be a super user to install ruby.
-
-
-If you fail to compile ruby, please send the detailed error report with the
-error log and machine/OS type, to help others.
-
-Some extension libraries may not get compiled because of lack of necessary
-external libraries and/or headers, then you will need to run '`make
-distclean-ext`' to remove old configuration after installing them in such
-case.
-
-## Copying
-
-See the file `COPYING`.
-
-## Feedback
-
-Questions about the Ruby language can be asked on the Ruby-Talk mailing list
-(http://www.ruby-lang.org/en/community/mailing-lists) or on websites like
-(http://stackoverflow.com).
-
-Bug reports should be filed at http://bugs.ruby-lang.org
-
-## The Author
-
-Ruby was originally designed and developed by Yukihiro Matsumoto (Matz) in
-1995.

- *
- *  By using binary search, finds a value from this array which meets
- *  the given condition in O(log n) where n is the size of the array.
- *
- *  You can use this method in two use cases: a find-minimum mode and
- *  a find-any mode.  In either case, the elements of the array must be
- *  monotone (or sorted) with respect to the block.
- *
- *  In find-minimum mode (this is a good choice for typical use case),
- *  the block must return true or false, and there must be an index i
- *  (0 <= i <= ary.size) so that:
- *
- *  - the block returns false for any element whose index is less than
- *    i, and
- *  - the block returns true for any element whose index is greater
- *    than or equal to i.
- *
- *  This method returns the i-th element.  If i is equal to ary.size,
- *  it returns nil.

- *     ary.bsearch {|x| x >=  -1 } #=> 0
- *     ary.bsearch {|x| x >= 100 } #=> nil
- *
- *  In find-any mode (this behaves like libc's bsearch(3)), the block
- *  must return a number, and there must be two indices i and j
- *  (0 <= i <= j <= ary.size) so that:
- *
- *  - the block returns a positive number for ary[k] if 0 <= k < i,
- *  - the block returns zero for ary[k] if i <= k < j, and
- *  - the block returns a negative number for ary[k] if
- *    j <= k < ary.size.
- *
- *  Under this condition, this method returns any element whose index
- *  is within i...j.  If i is equal to j (i.e., there is no element
- *  that satisfies the block), this method returns nil.
- *
- *     ary = [0, 4, 7, 10, 12]
- *     # try to find v such that 4 <= v < 8
- *     ary.bsearch {|x| 1 - x / 4 } #=> 4 or 7
- *     # try to find v such that 8 <= v < 10
- *     ary.bsearch {|x| 4 - x / 2 } #=> nil
- *
- *  You must not mix the two modes at a time; the block must always
- *  return either true/false, or always return a number.  It is
- *  undefined which value is actually picked up at each iteration.

- *  is compared with the first one of +other_ary+ using the <=> operator, then
- *  each of the second elements, etc...
- *  As soon as the result of any such comparison is non zero (i.e. the two
- *  corresponding elements are not equal), that result is returned for the
- *  whole array comparison.
- *
- *  If all the elements are equal, then the result is based on a comparison of
- *  the array lengths. Thus, two arrays are "equal" according to Array#<=> if,
- *  and only if, they have the same length and the value of each element is
- *  equal to the value of the corresponding element in the other array.
- *
- *  +nil+ is returned if the +other_ary+ is not an array or if the comparison
- *  of two elements returned +nil+.
- *
- *     [ "a", "a", "c" ]    <=> [ "a", "b", "c" ]   #=> -1
- *     [ 1, 2, 3, 4, 5, 6 ] <=> [ 1, 2 ]            #=> +1
- *     [ 1, 2 ]             <=> [ 1, :two ]         #=> nil

-/*
- *  Arrays are ordered, integer-indexed collections of any object.
- *
- *  Array indexing starts at 0, as in C or Java.  A negative index is assumed
- *  to be relative to the end of the array---that is, an index of -1 indicates
- *  the last element of the array, -2 is the next to last element in the
- *  array, and so on.
- *
- *  == Creating Arrays
- *
- *  A new array can be created by using the literal constructor
- *  <code>[]</code>.  Arrays can contain different types of objects.  For
- *  example, the array below contains an Integer, a String and a Float:
- *
- *     ary = [1, "two", 3.0] #=> [1, "two", 3.0]
- *
- *  An array can also be created by explicitly calling Array.new with zero, one
- *  (the initial size of the Array) or two arguments (the initial size and a
- *  default object).
- *
- *     ary = Array.new    #=> []
- *     Array.new(3)       #=> [nil, nil, nil]
- *     Array.new(3, true) #=> [true, true, true]
- *
- *  Note that the second argument populates the array with references to the
- *  same object.  Therefore, it is only recommended in cases when you need to
- *  instantiate arrays with natively immutable objects such as Symbols,
- *  numbers, true or false.
- *
- *  To create an array with separate objects a block can be passed instead.
- *  This method is safe to use with mutable objects such as hashes, strings or
- *  other arrays:
- *
- *     Array.new(4) { Hash.new } #=> [{}, {}, {}, {}]
- *
- *  This is also a quick way to build up multi-dimensional arrays:
- *
- *     empty_table = Array.new(3) { Array.new(3) }
- *     #=> [[nil, nil, nil], [nil, nil, nil], [nil, nil, nil]]
- *
- *  An array can also be created by using the Array() method, provided by
- *  Kernel, which tries to call #to_ary, then #to_a on its argument.
- *
- *	Array({:a => "a", :b => "b"}) #=> [[:a, "a"], [:b, "b"]]
- *
- *  == Example Usage
- *
- *  In addition to the methods it mixes in through the Enumerable module, the
- *  Array class has proprietary methods for accessing, searching and otherwise
- *  manipulating arrays.
- *
- *  Some of the more common ones are illustrated below.
- *
- *  == Accessing Elements
- *
- *  Elements in an array can be retrieved using the Array#[] method.  It can
- *  take a single integer argument (a numeric index), a pair of arguments
- *  (start and length) or a range. Negative indices start counting from the end,
- *  with -1 being the last element.
- *
- *     arr = [1, 2, 3, 4, 5, 6]
- *     arr[2]    #=> 3
- *     arr[100]  #=> nil
- *     arr[-3]   #=> 4
- *     arr[2, 3] #=> [3, 4, 5]
- *     arr[1..4] #=> [2, 3, 4, 5]
- *     arr[1..-3] #=> [2, 3, 4]
- *
- *  Another way to access a particular array element is by using the #at method
- *
- *     arr.at(0) #=> 1
- *
- *  The #slice method works in an identical manner to Array#[].
- *
- *  To raise an error for indices outside of the array bounds or else to
- *  provide a default value when that happens, you can use #fetch.
- *
- *     arr = ['a', 'b', 'c', 'd', 'e', 'f']
- *     arr.fetch(100) #=> IndexError: index 100 outside of array bounds: -6...6
- *     arr.fetch(100, "oops") #=> "oops"
- *
- *  The special methods #first and #last will return the first and last
- *  elements of an array, respectively.
- *
- *     arr.first #=> 1
- *     arr.last  #=> 6
- *
- *  To return the first +n+ elements of an array, use #take
- *
- *     arr.take(3) #=> [1, 2, 3]
- *
- *  #drop does the opposite of #take, by returning the elements after +n+
- *  elements have been dropped:
- *
- *     arr.drop(3) #=> [4, 5, 6]
- *
- *  == Obtaining Information about an Array
- *
- *  Arrays keep track of their own length at all times.  To query an array
- *  about the number of elements it contains, use #length, #count or #size.
- *
- *    browsers = ['Chrome', 'Firefox', 'Safari', 'Opera', 'IE']
- *    browsers.length #=> 5
- *    browsers.count #=> 5
- *
- *  To check whether an array contains any elements at all
- *
- *    browsers.empty? #=> false
- *
- *  To check whether a particular item is included in the array
- *
- *    browsers.include?('Konqueror') #=> false
- *
- *  == Adding Items to Arrays
- *
- *  Items can be added to the end of an array by using either #push or #<<
- *
- *    arr = [1, 2, 3, 4]
- *    arr.push(5) #=> [1, 2, 3, 4, 5]
- *    arr << 6    #=> [1, 2, 3, 4, 5, 6]
- *
- *  #unshift will add a new item to the beginning of an array.
- *
- *     arr.unshift(0) #=> [0, 1, 2, 3, 4, 5, 6]
- *
- *  With #insert you can add a new element to an array at any position.
- *
- *     arr.insert(3, 'apple')  #=> [0, 1, 2, 'apple', 3, 4, 5, 6]
- *
- *  Using the #insert method, you can also insert multiple values at once:
- *
- *     arr.insert(3, 'orange', 'pear', 'grapefruit')
- *     #=> [0, 1, 2, "orange", "pear", "grapefruit", "apple", 3, 4, 5, 6]
- *
- *  == Removing Items from an Array
- *
- *  The method #pop removes the last element in an array and returns it:
- *
- *     arr =  [1, 2, 3, 4, 5, 6]
- *     arr.pop #=> 6
- *     arr #=> [1, 2, 3, 4, 5]
- *
- *  To retrieve and at the same time remove the first item, use #shift:
- *
- *     arr.shift #=> 1
- *     arr #=> [2, 3, 4, 5]
- *
- *  To delete an element at a particular index:
- *
- *     arr.delete_at(2) #=> 4
- *     arr #=> [2, 3, 5]
- *
- *  To delete a particular element anywhere in an array, use #delete:
- *
- *     arr = [1, 2, 2, 3]
- *     arr.delete(2) #=> 2
- *     arr #=> [1,3]
- *
- *  A useful method if you need to remove +nil+ values from an array is
- *  #compact:
- *
- *     arr = ['foo', 0, nil, 'bar', 7, 'baz', nil]
- *     arr.compact  #=> ['foo', 0, 'bar', 7, 'baz']
- *     arr          #=> ['foo', 0, nil, 'bar', 7, 'baz', nil]
- *     arr.compact! #=> ['foo', 0, 'bar', 7, 'baz']
- *     arr          #=> ['foo', 0, 'bar', 7, 'baz']
- *
- *  Another common need is to remove duplicate elements from an array.
- *
- *  It has the non-destructive #uniq, and destructive method #uniq!
- *
- *     arr = [2, 5, 6, 556, 6, 6, 8, 9, 0, 123, 556]
- *     arr.uniq #=> [2, 5, 6, 556, 8, 9, 0, 123]
- *
- *  == Iterating over Arrays
- *
- *  Like all classes that include the Enumerable module, Array has an each
- *  method, which defines what elements should be iterated over and how.  In
- *  case of Array's #each, all elements in the Array instance are yielded to
- *  the supplied block in sequence.
- *
- *  Note that this operation leaves the array unchanged.
- *
- *     arr = [1, 2, 3, 4, 5]
- *     arr.each { |a| print a -= 10, " " }
- *     # prints: -9 -8 -7 -6 -5
- *     #=> [1, 2, 3, 4, 5]
- *
- *  Another sometimes useful iterator is #reverse_each which will iterate over
- *  the elements in the array in reverse order.
- *
- *     words = %w[first second third fourth fifth sixth]
- *     str = ""
- *     words.reverse_each { |word| str += "#{word} " }
- *     p str #=> "sixth fifth fourth third second first "
- *
- *  The #map method can be used to create a new array based on the original
- *  array, but with the values modified by the supplied block:
- *
- *     arr.map { |a| 2*a }   #=> [2, 4, 6, 8, 10]
- *     arr                   #=> [1, 2, 3, 4, 5]
- *     arr.map! { |a| a**2 } #=> [1, 4, 9, 16, 25]
- *     arr                   #=> [1, 4, 9, 16, 25]
- *
- *  == Selecting Items from an Array
- *
- *  Elements can be selected from an array according to criteria defined in a
- *  block.  The selection can happen in a destructive or a non-destructive
- *  manner.  While the destructive operations will modify the array they were
- *  called on, the non-destructive methods usually return a new array with the
- *  selected elements, but leave the original array unchanged.
- *
- *  === Non-destructive Selection
- *
- *     arr = [1, 2, 3, 4, 5, 6]
- *     arr.select { |a| a > 3 }     #=> [4, 5, 6]
- *     arr.reject { |a| a < 3 }     #=> [3, 4, 5, 6]
- *     arr.drop_while { |a| a < 4 } #=> [4, 5, 6]
- *     arr                          #=> [1, 2, 3, 4, 5, 6]
- *
- *  === Destructive Selection
- *
- *  #select! and #reject! are the corresponding destructive methods to #select
- *  and #reject
- *
- *  Similar to #select vs. #reject, #delete_if and #keep_if have the exact
- *  opposite result when supplied with the same block:
- *
- *     arr.delete_if { |a| a < 4 } #=> [4, 5, 6]
- *     arr                         #=> [4, 5, 6]
- *
- *     arr = [1, 2, 3, 4, 5, 6]
- *     arr.keep_if { |a| a < 4 } #=> [1, 2, 3]
- *     arr                       #=> [1, 2, 3]
- *

-# determines if a board is punable, meaning that there is no possibility that it
-# can be filled up with pieces.  A board is prunable if there is a grouping of unfilled spaces
-# that are not a multiple of five.  The following board is an example of a prunable board:
-#    0 0 1 0 0
-#     0 1 0 0 0
-#    1 1 0 0 0
-#     0 1 0 0 0
-#    0 0 0 0 0
-#       ...
-#
-# This board is prunable because the top left corner is only 3 bits in area, no piece will ever fit it
-# parameters:
-#   board -- an initial bit board (6 bit padded rows, see blank_board for format)
-#   location -- starting location, everything above and to the left is already full
-#   slotting -- set to true only when testing initial pieces, when filling normally
-#               additional assumptions are possible
-#
-# Algorithm:
-#    The algorithm starts at the top row (as determined by location) and iterates a row at a time
-#    maintainng counts of active open areas (kept in the collector array) each collector contains
-#    three values at the start of an iteration:
-#          0: mask of bits that would be adjacent to the collector in this row
-#          1: the number of bits collected so far
-#          2: a scratch space starting as zero, but used during the computation to represent

-#   in the cycle.  We still need to keep checking all the permutations, but our probability of finding one will
-#   diminsh over time.  Since we are TOLD how many to search for this lets us exit before checking all pieces

-Hello there, Izchak Miller was my father.  When I was younger I spent 
-many a night, hunched over the keyboard with a cup of tea, playing 
-nethack with him and my brother.  my dad was a philosopher with a strong 
-weakness for fantasy/sci fi.  I remember when he started to get involved 
-with the Nethack team- my brother's Dungeons and Dragons monster book 
-found a regular place beside my dad's desk. it's nice to see him living 
-on in the game he loved so much :-).

- * INTEGER_PACK_2COMP is not set:
- *   0 <= val < 2**(numwords*(wordsize*CHAR_BIT-nails)) if !INTEGER_PACK_NEGATIVE
- *   -2**(numwords*(wordsize*CHAR_BIT-nails)) < val <= 0 if INTEGER_PACK_NEGATIVE
- *
- * INTEGER_PACK_2COMP is set:
- *   -2**(numwords*(wordsize*CHAR_BIT-nails)-1) <= val <= 2**(numwords*(wordsize*CHAR_BIT-nails)-1)-1 if !INTEGER_PACK_NEGATIVE
- *   -2**(numwords*(wordsize*CHAR_BIT-nails)) <= val <= -1 if INTEGER_PACK_NEGATIVE
- *
- * INTEGER_PACK_2COMP without INTEGER_PACK_NEGATIVE means sign extension.
- * INTEGER_PACK_2COMP with INTEGER_PACK_NEGATIVE mean assuming the higher bits are 1.
- *
- * Note that this function returns 0 when numwords is zero and
- * INTEGER_PACK_2COMP is set but INTEGER_PACK_NEGATIVE is not set.

-Statement of Purpose
-
-The laws of most jurisdictions throughout the world automatically confer exclusive Copyright and Related Rights (defined below) upon the creator and subsequent owner(s) (each and all, an "owner") of an original work of authorship and/or a database (each, a "Work").
-
-Certain owners wish to permanently relinquish those rights to a Work for the purpose of contributing to a commons of creative, cultural and scientific works ("Commons") that the public can reliably and without fear of later claims of infringement build upon, modify, incorporate in other works, reuse and redistribute as freely as possible in any form whatsoever and for any purposes, including without limitation commercial purposes. These owners may contribute to the Commons to promote the ideal of a free culture and the further production of creative, cultural and scientific works, or to gain reputation or greater distribution for their Work in part through the use and efforts of others.
-
-For these and/or other purposes and motivations, and without any expectation of additional consideration or compensation, the person associating CC0 with a Work (the "Affirmer"), to the extent that he or she is an owner of Copyright and Related Rights in the Work, voluntarily elects to apply CC0 to the Work and publicly distribute the Work under its terms, with knowledge of his or her Copyright and Related Rights in the Work and the meaning and intended legal effect of CC0 on those rights.
-
-1. Copyright and Related Rights. A Work made available under CC0 may be protected by copyright and related or neighboring rights ("Copyright and Related Rights"). Copyright and Related Rights include, but are not limited to, the following:
-
-    the right to reproduce, adapt, distribute, perform, display, communicate, and translate a Work;
-    moral rights retained by the original author(s) and/or performer(s);
-    publicity and privacy rights pertaining to a person's image or likeness depicted in a Work;
-    rights protecting against unfair competition in regards to a Work, subject to the limitations in paragraph 4(a), below;
-    rights protecting the extraction, dissemination, use and reuse of data in a Work;
-    database rights (such as those arising under Directive 96/9/EC of the European Parliament and of the Council of 11 March 1996 on the legal protection of databases, and under any national implementation thereof, including any amended or successor version of such directive); and
-    other similar, equivalent or corresponding rights throughout the world based on applicable law or treaty, and any national implementations thereof.
-
-2. Waiver. To the greatest extent permitted by, but not in contravention of, applicable law, Affirmer hereby overtly, fully, permanently, irrevocably and unconditionally waives, abandons, and surrenders all of Affirmer's Copyright and Related Rights and associated claims and causes of action, whether now known or unknown (including existing as well as future claims and causes of action), in the Work (i) in all territories worldwide, (ii) for the maximum duration provided by applicable law or treaty (including future time extensions), (iii) in any current or future medium and for any number of copies, and (iv) for any purpose whatsoever, including without limitation commercial, advertising or promotional purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each member of the public at large and to the detriment of Affirmer's heirs and successors, fully intending that such Waiver shall not be subject to revocation, rescission, cancellation, termination, or any other legal or equitable action to disrupt the quiet enjoyment of the Work by the public as contemplated by Affirmer's express Statement of Purpose.
-
-3. Public License Fallback. Should any part of the Waiver for any reason be judged legally invalid or ineffective under applicable law, then the Waiver shall be preserved to the maximum extent permitted taking into account Affirmer's express Statement of Purpose. In addition, to the extent the Waiver is so judged Affirmer hereby grants to each affected person a royalty-free, non transferable, non sublicensable, non exclusive, irrevocable and unconditional license to exercise Affirmer's Copyright and Related Rights in the Work (i) in all territories worldwide, (ii) for the maximum duration provided by applicable law or treaty (including future time extensions), (iii) in any current or future medium and for any number of copies, and (iv) for any purpose whatsoever, including without limitation commercial, advertising or promotional purposes (the "License"). The License shall be deemed effective as of the date CC0 was applied by Affirmer to the Work. Should any part of the License for any reason be judged legally invalid or ineffective under applicable law, such partial invalidity or ineffectiveness shall not invalidate the remainder of the License, and in such case Affirmer hereby affirms that he or she will not (i) exercise any of his or her remaining Copyright and Related Rights in the Work or (ii) assert any associated claims and causes of action with respect to the Work, in either case contrary to Affirmer's express Statement of Purpose.
-
-4. Limitations and Disclaimers.
-
-    No trademark or patent rights held by Affirmer are waived, abandoned, surrendered, licensed or otherwise affected by this document.
-    Affirmer offers the Work as-is and makes no representations or warranties of any kind concerning the Work, express, implied, statutory or otherwise, including without limitation warranties of title, merchantability, fitness for a particular purpose, non infringement, or the absence of latent or other defects, accuracy, or the present or absence of errors, whether or not discoverable, all to the greatest extent permissible under applicable law.
-    Affirmer disclaims responsibility for clearing rights of other persons that may apply to the Work or any use thereof, including without limitation any person's Copyright and Related Rights in the Work. Further, Affirmer disclaims responsibility for obtaining any necessary consents, permissions or other rights required for any use of the Work.

- * <dt>Fixed number of parameters</dt>
- * <dd>
- *     This form is a normal C function, excepting it takes

- *  Document-class: Continuation
- *
- *  Continuation objects are generated by Kernel#callcc,
- *  after having +require+d <i>continuation</i>. They hold
- *  a return address and execution context, allowing a nonlocal return
- *  to the end of the <code>callcc</code> block from anywhere within a
- *  program. Continuations are somewhat analogous to a structured
- *  version of C's <code>setjmp/longjmp</code> (although they contain
- *  more state, so you might consider them closer to threads).
- *
- *  For instance:
- *
- *     require "continuation"
- *     arr = [ "Freddie", "Herbie", "Ron", "Max", "Ringo" ]
- *     callcc{|cc| $cc = cc}
- *     puts(message = arr.shift)
- *     $cc.call unless message =~ /Max/
- *
- *  <em>produces:</em>
- *
- *     Freddie
- *     Herbie
- *     Ron
- *     Max
- *
- *  This (somewhat contrived) example allows the inner loop to abandon
- *  processing early:
- *
- *     require "continuation"
- *     callcc {|cont|
- *       for i in 0..4
- *         print "\n#{i}: "
- *         for j in i*5...(i+1)*5
- *           cont.call() if j == 17
- *           printf "%3d", j
- *         end
- *       end
- *     }
- *     puts
- *
- *  <em>produces:</em>
- *
- *     0:   0  1  2  3  4
- *     1:   5  6  7  8  9
- *     2:  10 11 12 13 14

- *  Document-class: Fiber
- *
- *  Fibers are primitives for implementing light weight cooperative
- *  concurrency in Ruby. Basically they are a means of creating code blocks
- *  that can be paused and resumed, much like threads. The main difference
- *  is that they are never preempted and that the scheduling must be done by
- *  the programmer and not the VM.
- *
- *  As opposed to other stackless light weight concurrency models, each fiber
- *  comes with a small 4KB stack. This enables the fiber to be paused from deeply
- *  nested function calls within the fiber block.
- *
- *  When a fiber is created it will not run automatically. Rather it must
- *  be explicitly asked to run using the <code>Fiber#resume</code> method.
- *  The code running inside the fiber can give up control by calling
- *  <code>Fiber.yield</code> in which case it yields control back to caller
- *  (the caller of the <code>Fiber#resume</code>).
- *
- *  Upon yielding or termination the Fiber returns the value of the last
- *  executed expression
- *
- *  For instance:
- *
- *    fiber = Fiber.new do
- *      Fiber.yield 1
- *      2
- *    end
- *
- *    puts fiber.resume
- *    puts fiber.resume
- *    puts fiber.resume
- *
- *  <em>produces</em>
- *
- *    1
- *    2
- *    FiberError: dead fiber called
- *
- *  The <code>Fiber#resume</code> method accepts an arbitrary number of
- *  parameters, if it is the first call to <code>resume</code> then they
- *  will be passed as block arguments. Otherwise they will be the return
- *  value of the call to <code>Fiber.yield</code>
- *
- *  Example:
- *
- *    fiber = Fiber.new do |first|
- *      second = Fiber.yield first + 2
- *    end
- *
- *    puts fiber.resume 10
- *    puts fiber.resume 14
- *    puts fiber.resume 18
- *
- *  <em>produces</em>
- *
- *    12
- *    14

-Usage
-
-The make task `update-coverage' retrieves simplecov for coverage report.
-
-COVERAGE=1 make test-all TESTS=test/cgi
-
-it generate test coverage to coverage directory.
-
-Limitation
-
- * test_coverage.rb and test_process.rb broke test suit with SimpleCov
- * some tests failed randomly.
-
-TODO
-
- * more reduce bundled simplecov(additional configuration, formatter, etc)
- * measure rubyspec coverage

- *
- *  <code>*</code>::

- *
- *  <code>**</code>::

- *  <code>?</code>::

- *
- *  <code>[set]</code>::

- *  <code>{p,q}</code>::

- *
- *  <code> \\ </code>::

- *
- *    Note that this means you cannot use backslash on windows as part of a

+* 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
+     and ext/extmk.rb(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'

-
-	* include/ruby/intern.h, thread_pthread.c (rb_reserved_fd_p,
-	  RB_RESERVED_FD_P): added.  This C API is to limit to access

-	  CRuby, return 1 if fd is communication pipe.
-	  If your application needs to close all file descriptors to
-	  present resource leak, skip internal fds using this C API.
-	  We also define a macro RB_RESERVED_FD_P(fd).  So you can write
-	    #ifndef RB_RESERVED_FD_P
-	    #define RB_RESERVED_FD_P(fd) 0

-
-	* thread_pthread.c (get_stack): pthread_attr_getstack() doesn't

-	* thread_pthread.c (thread_start_func_1): don't use inaccurate

-	  https://github.com/eregon/ruby/tree/benchmark
-	  patched by Benoit Daloze. [ruby-core:37593] [Bug #4940]
-
-	* lib/benchmark (Benchmark#bmbm): bmbm should be consistent with bm
-	  for the return value.
-
-	* test/benchmark: remove preemptive test instead of skipping
-	  I removed the preemptive test I wrote for Feature #4197.
-	  I'll add it back when the implementation will be able to satisfy it.
-
-	* lib/benchmark (Benchmark#bmbm): remove useless explicit call,
-	  #format is an alias of #to_s test/benchmark: add a test for
-	  format of long time.
-
-	* lib/benchmark: fix label width: always add 1 to ensure there is a
-	  space delimiter even with times over 100s
-	  When I asked for Feature #4197, I wanted to make delimiting spaces
-	  consistent for #bm and #bmbm.
-	  But with times over 100s, the output contains no space between the
-	  label and the first time (user).
-	  Now both ensure there is always a space, even if that means 3 spaces
-	  with times under 10s (because it is formatted as %10.6f)
-
-	* test/benchmark: let labels be a constant
-	  lib/benchmark (Benchmark#realtime): avoid creating an unused Proc
-	  lib/benchmark (Benchmark#benchmark): use ensure clause to restore

-	  several environment (we found a crash on FreeBSD).
-	  And remove const value "buff_size", and define CCP_READ_BUFF_SIZE
-	  macro.

-	  If outside-event such as signal or Thread#kill was occurred

-	  waits this communication-pipe with select(2)).

-
-	* ext/syck/rubyext.c (mktime_do): avoid buffer overrun, by
-	  silently ignoring lesser significant digits.  Required buffer
-	  length can be computable so you might at first think of
-	  allocating enough memory space on the fly using alloca().  That
-	  is a wrong idea because when using alloca there is always risk
-	  of integer overflow.  A function that accepts outer-process
-	  resources like this should not blindly trust its inputs.  In
-	  this particular case we just want to generate milliseconds
-	  resolution by strtod() so the string in question needs no more
-	  length than what we originally have.  Ignoring lesser
-	  significant digits should suffice I believe.

-	* test/test_syslog.rb:
-	  Skip syslog tests that rely on LOG_PERROR unless it's defined
-
-	  Instead of checking looking at the platform to determine if the tests
-	  relying on LOG_PERROR should be run, look for the definition of the
-	  constant as this will be robust against all platforms as long as the
-	  underlying syslog.c code sets it up correctly.
-
-	  This specifically addresses failures on Solaris 9.
-
-	  Use LOG_PID instead of LOG_PERROR in Syslog.open test
-
-	  LOG_PERROR isn't a POSIX option for syslog, so it fails on platforms
-	  that don't define it.  Solaris 9 and 10 are examples of this.
-
-	  Use LOG_PID instead.

-	  into a int (loses data here), and then casted back to char*
-	  by automatic integral promotion to fit to the prototype of

-	* class.c, constant.h, gc.c, method.h, object.c, variable.c,
-	  vm_insnhelper.c: use struct rb_constant_entry_t as entry of

-
-	* test/net/imap/test_imap.rb: "localhost" not guaranteed to
-	  resolve to "127.0.0.1".  On my machine it is "::1" instead.
-	  The problem is, you have to connect to the imaps server via
-	  the canonical name written in a server certificate, and that
-	  of the server.cert is "localhost".  So you have to listen to
-	  the address of what "localhost" resolves to.  I think this
-	  situation cannot be resolved in a handy manner because the
-	  test "test_imaps_post_connection_check" is actually
-	  expecting to connect to a server via an address other than
-	  the CN.  On my machine several assertions won't pass because
-	  the test cannot connect to the server.

-	* vm_method.c (rb_unlink_method_entry, rb_sweep_method_entry):
-	  added.  Unlinked method entries are collected to
-	  vm->unlinked_method_entry_list.  On the GC timing, mark all method
-	  entries which are on all living threads.  Only non-marked method
-	  entries are collected.  This hack prevents releasing living method
-	  entry.
-	  [Performance Consideration] Since this Method Entry GC (MEGC)
-	  doesn't occur frequently, MEGC will not be a performance bottleneck.
-	  However, to traverse living method entries, every control frame push
-	  needs to clear cfp->me field.  This will be a performance issue
-	  (because pushing control frame is occurred frequently).

-	  Now, support longnam-keys (e.g. '%CTT' on tkdnd-2.0; however, still
-	  not support tkdnd-2.0 on tkextlib), and symbols of parameters (e.g.
-	  :widget=>'%W', :keycode=>'%k', '%x'=>:x, '%X'=>:root_x, and so on;
-	  those are attributes of event object). It means that Ruby/Tk accepts
-	  not only "widget.bind(ev, '%W', '%k', ...){|w, k, ...| ... }", but
-	  also "widget.bind(ev, :widget, :keycode, ...){|w, k, ...| ... }".
-	  It is potentially incompatible, when user passes symbols to the
-	  arguments of the callback block (the block receives the symbols as
-	  strings). I think that is very rare case (probably, used by Ruby/Tk
-	  experts only). When causes such trouble, please give strings instead
-	  of such symbol parameters (e.g. call Symbol#to_s method).

-
-	* ext/tk/*: full update Ruby/Tk to support Ruby(1.9|1.8) and Tc/Tk8.5.
-
-	* ext/tk/lib/tkextlib/tile.rb: [incompatible] remove TileWidgets'
-	  instate/state/identify method to avoid the conflict with standard
-	  widget options. Those methods are renamed to ttk_instate/ttk_state/
-	  ttk_identify (tile_instate/tile_state/tile_identify are available
-	  too). Although I don't recommend, if you really need old methods,
-	  please define "Tk::USE_OBSOLETE_TILE_STATE_METHOD = true" before
-	  "require 'tkextlib/tile'".
-
-	* ext/tk/lib/tkextlib/tile.rb: "Tk::Tile::__Import_Tile_Widgets__!"
-	  is obsolete. It outputs warning. To control default widget set,
-	  use "Tk.default_widget_set = :Ttk".
-
-	* ext/tk/lib/tk.rb: __IGNORE_UNKNOWN_CONFIGURE_OPTION__ method and
-	  __set_IGNORE_UNKNOWN_CONFIGURE_OPTION__!(mode) method are defined
-	  as module methods of TkConfigMethod. It may help users to wrap old
-	  Ruby/Tk scripts (use standard widgets) to force to use Ttk widgets.
-	  Ttk widgets don't have some options of standard widgets which are
-	  control the view of widgets. When set ignore-mode true, configure
-	  method tries to ignore such unknown options with no exception.
-	  Of course, it may raise other troubles on the GUI design.
-	  So, those are a little danger methods.
-
-	* ext/tk/lib/tk/itemconfig.rb: __IGNORE_UNKNOWN_CONFIGURE_OPTION__
-	  method and __set_IGNORE_UNKNOWN_CONFIGURE_OPTION__!(mode) method
-	  are defined as module methods of TkItemConfigMethod as the same
-	  purpose as TkConfigMethod's ones.
-
-	* ext/tk/sample/ttk_wrapper.rb: A new example. This is a tool for
-	  wrapping old Ruby/Tk scripts (which use standard widgets) to use
-	  Ttk (Tile) widgets as default.
-
-	* ext/tk/sample/tkextlib/tile/demo.rb: use ttk_instate/ttk_state
-	  method instead of instate/state method.
-
-	* ext/tk/lib/tk/root, ext/tk/lib/tk/namespace.rb,
-	  ext/tk/lib/tk/text.rb, ext/tk/lib/tkextlib/*: some 'instance_eval's
-	  are replaced to "instance_exec(self)".
-
-	* ext/tk/lib/tk/event.rb: bug fix on KEY_TBL and PROC_TBL (?x is not
-	  a character code on Ruby1.9).
-
-	* ext/tk/lib/tk/variable.rb: support new style of operation argument
-	  on Tcl/Tk's 'trace' command for variables.
-
-	* ext/tk/sample/demos-jp/widget, ext/tk/sample/demos-en/widget: bug fix
-
-	* ext/tk/sample/demos-jp/textpeer.rb,
-	  ext/tk/sample/demos-en/textpeer.rb: new widget demo.
-
-	* ext/tk/tcltklib.c: decrease SEGV troubles (probably)
-
-	* ext/tk/lib/tk.rb: remove Thread.critical access if Ruby1.9
-
-	* ext/tk/lib/tk/multi-tk.rb: support Ruby1.9 (probably)
-
-	* ext/tk/lib/tkextlib/tile.rb: add method to define Tcl/Tk command
-	  to make Tcl/Tk theme sources (based on different version of Tile
-	  extension) available.
-	  (Tk::Tile::__define_LoadImages_proc_for_compatibility__)
-
-	* ext/tk/lib/tk.rb, ext/tk/lib/tk/wm.rb: support dockable frames
-	  (Tcl/Tk8.5 feature). 'wm' command can treat many kinds of widgets
-	  as toplevel widgets.
-
-	* ext/tk/lib/tkextlib/tile/style.rb: ditto.
-	  (Tk::Tile::Style.__define_wrapper_proc_for_compatibility__)
-
-	* ext/tk/lib/tk/font.rb: add actual_hash and metrics_hash to get
-	  properties as a hash. metrics_hash method returns a boolean value
-	  for 'fixed' option. But metrics method returns numeric value
-	  (0 or 1) for 'fixed' option, because of backward compatibility.
-
-	* ext/tk/lib/tk/timer.rb: sometimes fail to set callback procedure.
-
-	* ext/tk/lib/tk.rb: add Tk.sleep and Tk.wakeup method. Tk.sleep
-	  doesn't block the eventloop. It will be better to use the method
-	  in event callbacks.
-
-	* ext/tk/sample/tksleep_sample.rb: sample script about Tk.sleep.

-
-	* ext/tk/lib/tk.rb, ext/tk/lib/*: make default widget set
-	  switchable between Tk (standard Tcl/Tk widget set) and
-	  Ttk (Tile). Initial default widget set is Tk. Now, toplevel
-	  widget classes are removed and defined as aliases.
-	  For example, "TkButton" is an alias of the "Tk::Button" class.
-	  Those aliases are replaced when switching default widget set.
-	  "Tk.default_widget_set=" is the method for switching default
-	  widget set. "Tk.default_widget_set = :Ttk" defines Ttk (Tile)
-	  widget set as default. It means that "TkButton" denotes
-	  "Tk::Tile::Button" class. And then, "TkButton.new" creates
-	  a Tk::Tile::Button widget. Of course, you can back to use
-	  standard Tk widgets as the default widget set by calling
-	  "Tk.default_widget_set = :Tk", whenever you want. Based on
-	  the feature, you can use Ttk widget styling engine on your
-	  old Ruby/Tk application without modifying its source, if you
-	  don't use widget options unsupported on Ttk widgets (At first,
-	  call "Tk.default_widget_set = :Ttk", and next load and run
-	  your application).
-	  This is one step for supporting Tcl/Tk8.5 features.
