-		       Version 2, June 1991
+Ruby is copyrighted free software by Yukihiro Matsumoto <matz@netlab.jp>.
+You can redistribute it and/or modify it under either the terms of the
+2-clause BSDL (see the file BSDL), or the conditions below:
 
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.
-     59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
+  1. You may make and give away verbatim copies of the source form of the
+     software without restriction, provided that you duplicate all of the
+     original copyright notices and associated disclaimers.
 
-			    Preamble
+  2. You may modify your copy of the software in any way, provided that
+     you do at least ONE of the following:
 
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users.  This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it.  (Some other Free Software Foundation software is covered by
-the GNU Library General Public License instead.)  You can apply it to
-your programs, too.
+       a) place your modifications in the Public Domain or otherwise
+          make them Freely Available, such as by posting said
+	  modifications to Usenet or an equivalent medium, or by allowing
+	  the author to include your modifications in the software.
 
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
+       b) use the modified software only within your corporation or
+          organization.
 
-  To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
+       c) give non-standard binaries non-standard names, with
+          instructions on where to get the original software distribution.
 
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have.  You must make sure that they, too, receive or can get the
-source code.  And you must show them these terms so they know their
-rights.
+       d) make other distribution arrangements with the author.
 
-  We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
+  3. You may distribute the software in object code or binary form,
+     provided that you do at least ONE of the following:
 
-  Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software.  If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
+       a) distribute the binaries and library files of the software,
+	  together with instructions (in the manual page or equivalent)
+	  on where to get the original distribution.
 
-  Finally, any free program is threatened constantly by software
-patents.  We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary.  To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
+       b) accompany the distribution with the machine-readable source of
+	  the software.
 
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-		    GNU GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+       c) give non-standard binaries non-standard names, with
+          instructions on where to get the original software distribution.
 
-  0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License.  The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language.  (Hereinafter, translation is included without limitation in
-the term "modification".)  Each licensee is addressed as "you".
+       d) make other distribution arrangements with the author.
 
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
+  4. You may modify and include the part of the software into any other
+     software (possibly commercial).  But some files in the distribution
+     are not written by the author, so that they are not under these terms.
 
-  1. You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
+     For the list of those files and their copying conditions, see the
+     file LEGAL.
 
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
+  5. The scripts and library files supplied as input to or produced as 
+     output from the software do not automatically fall under the
+     copyright of the software, but belong to whomever generated them, 
+     and may be sold commercially, and may be aggregated with this
+     software.
 
-  2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-    a) You must cause the modified files to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    b) You must cause any work that you distribute or publish, that in
-    whole or in part contains or is derived from the Program or any
-    part thereof, to be licensed as a whole at no charge to all third
-    parties under the terms of this License.
-
-    c) If the modified program normally reads commands interactively
-    when run, you must cause it, when started running for such
-    interactive use in the most ordinary way, to print or display an
-    announcement including an appropriate copyright notice and a
-    notice that there is no warranty (or else, saying that you provide
-    a warranty) and that users may redistribute the program under
-    these conditions, and telling the user how to view a copy of this
-    License.  (Exception: if the Program itself is interactive but
-    does not normally print such an announcement, your work based on
-    the Program is not required to print an announcement.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
-    a) Accompany it with the complete corresponding machine-readable
-    source code, which must be distributed under the terms of Sections
-    1 and 2 above on a medium customarily used for software interchange; or,
-
-    b) Accompany it with a written offer, valid for at least three
-    years, to give any third party, for a charge no more than your
-    cost of physically performing source distribution, a complete
-    machine-readable copy of the corresponding source code, to be
-    distributed under the terms of Sections 1 and 2 above on a medium
-    customarily used for software interchange; or,
-
-    c) Accompany it with the information you received as to the offer
-    to distribute corresponding source code.  (This alternative is
-    allowed only for noncommercial distribution and only if you
-    received the program in object code or executable form with such
-    an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it.  For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable.  However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License.  Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
-  5. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Program or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
-  6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
-  7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded.  In such case, this License incorporates
-the limitation as if written in the body of this License.
-
-  9. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time.  Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number.  If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation.  If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
-  10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission.  For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this.  Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
-			    NO WARRANTY
-
-  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
-  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.
-
-		     END OF TERMS AND CONDITIONS
-
-	    How to Apply These Terms to Your New Programs
-
-  If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
-  To do so, attach the following notices to the program.  It is safest
-to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the program's name and a brief idea of what it does.>
-    Copyright (C) 19yy  <name of author>
-
-    This program is free software; you can redistribute it and/or modify
-    it under the terms of the GNU General Public License as published by
-    the Free Software Foundation; either version 2 of the License, or
-    (at your option) any later version.
-
-    This program is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
-    GNU General Public License for more details.
-
-    You should have received a copy of the GNU General Public License
-    along with this program; if not, write to the Free Software
-    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
-
-
-Also add information on how to contact you by electronic and paper mail.
-
-If the program is interactive, make it output a short notice like this
-when it starts in an interactive mode:
-
-    Gnomovision version 69, Copyright (C) 19yy name of author
-    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
-    This is free software, and you are welcome to redistribute it
-    under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License.  Of course, the commands you use may
-be called something other than `show w' and `show c'; they could even be
-mouse-clicks or menu items--whatever suits your program.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the program, if
-necessary.  Here is a sample; alter the names:
-
-  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
-  `Gnomovision' (which makes passes at compilers) written by James Hacker.
-
-  <signature of Ty Coon>, 1 April 1989
-  Ty Coon, President of Vice
-
-This General Public License does not permit incorporating your program into
-proprietary programs.  If your program is a subroutine library, you may
-consider it more useful to permit linking proprietary applications with the
-library.  If this is what you want to do, use the GNU Library General
-Public License instead of this License.

+     WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR

+
+	* gc.c: change RGENGC_CHECK_MODE (>= 2) logic.
+	  Basically, make an object graph of all of living objects before and
+	  after marking and check status.
+
+	  [Before marking: check WB sanity]
+	  If there is a non-old object `obj' pointed from old object
+	  (`parent') then `parent' or `obj' should be remembered.
+
+	  [After marking: check marking miss]
+	  Traversible objects with the object graph should be marked.
+	  (However, this alert about objects pointed by machine context
+	   can be false positive. We only display alert.)
+
+	  [Implementation memo]
+	  objspace_allrefs() creates an object graph.
+	  The object graph is represented by st_table, key is object (VALUE)
+	  and value is referring objects. Referring objects are stored by
+	  "struct reflist".
+
+	* gc.c (init_mark_stack): do not use push_mark_stack_chunk() at init.
+	  This pre-allocation causes failure on is_mark_stack_empty()
+	  without any pushing.

+
+	* gc.c: add support to estimate increase of oldspace memory usage.
+	  This is another approach to solve an issue discussed at r43530.
+	  This feature is disabled as default.
+
+	  This feature measures an increment of memory consumption by oldgen
+	  objects. It measures memory consumption for each objects when
+	  the object is promoted. However, measurement of memory consumption
+	  is not accurate now. So that this measurement is `estimation'.
+
+	  To implement this feature, move memsize_of() function from
+	  ext/objspace/objspace.c and expose rb_obj_memsize_of().
+
+	  Some memsize() functions for T_DATA (T_TYPEDDATA) have problem to
+	  measure memory size, so that we ignores T_DATA objects now.
+	  For example, some functions skip NULL check for pointer.
+
+	  The macro RGENGC_ESTIMATE_OLDSPACE enables/disables this feature,
+	  and turned off as default.
+
+	  We need to compare 3gen GC and this feature carefully.
+	  (it is possible to enable both feature)
+	  We need a help to compare them.
+
+	* internal.h: expose rb_obj_memsize_of().
+
+	* ext/objspace/objspace.c: use rb_obj_memsize_of() function.

+
+	* gc.c: add 3gen GC patch, but disabled as default.
+
+	  RGenGC is designed as 2 generational GC, young and old generation.
+	  Young objects will be promoted to old objects after one GC.
+	  Old objects are not collect until major (full) GC.
+
+	  The issue of this approach is some objects can promoted as old
+	  objects accidentally and not freed until major GC.
+	  Major GC is not frequently so short-lived but accidentally becoming
+	  old objects are not freed.
+
+	  For example, the program "loop{Array.new(1_000_000)}" consumes huge
+	  memories because short lived objects (an array which has 1M
+	  elements) are promoted while GC and they are not freed before major
+	  GC.
+
+	  To solve this problem, generational GC with more generations
+	  technique is known. This patch implements three generations gen GC.
+
+	  At first, newly created objects are "Infant" objects.
+	  After surviving one GC, "Infant" objects are promoted to "Young"
+	  objects.
+	  "Young" objects are promoted to "Old" objects after surviving
+	  next GC.
+	  "Infant" and "Young" objects are collected if it is not marked
+	  while minor GC. So that this technique solves this problem.
+
+	  Representation of generations:
+	  * Infant: !FL_PROMOTED and !oldgen_bitmap [00]
+	  * Young :  FL_PROMOTED and !oldgen_bitmap [10]
+	  * Old   :  FL_PROMOTED and  oldgen_bitmap [11]
+
+	  The macro "RGENGC_THREEGEN" enables/disables this feature, and
+	  turned off as default because there are several problems.
+	  (1) Failed sometimes (Heisenbugs).
+	  (2) Performance down.
+	      Especially on write barriers. We need to detect Young or Old
+	      object by oldgen_bitmap. It is slower than checking flags.
+
+	  To evaluate this feature on more applications, I commit this patch.
+	  Reports are very welcome.
+
+	  This patch includes some refactoring (renaming names, etc).
+
+	* include/ruby/ruby.h: catch up 3gen GC.

+
+	  WBs had located before creating reference between a klass
+	  and constant value. It causes GC bug.
+
+	    # pseudo code:
+	    WB(klass, value); # WB and remember klass
+	    st_insert(klass->const_table, const_id, value);
+
+	  `st_insert()' can cause GC before inserting `value' and
+	  forget `klass' from the remember set. After that, relationship
+	  between `klass' and `value' are created with constant table.
+	  Now, `value' can be young (shady) object and `klass' can be old
+	  object, without remembering `klass' object.
+	  At the next GC, old `klass' object will be skipped and
+	  young (shady) `value' will be miss-collected. -> GC bug
+
+	  Lesson: The place of a WB is important.

+Mon May 27 18:57:28 2013  Koichi Sasada  <ko1@atdot.net>
+
+	* ext/objspace/objspace.c: support ObjectSpace.trace_object_allocations.
+	  Read the following test to know HOWTO.
+	  This feature is a sample of RUBY_INTERNAL_EVENT.
+
+	* test/objspace/test_objspace.rb: add a test.

+
+	* vm_trace.c (rb_postponed_job_flush, rb_postponed_job_register): use

+
+Mon May 27 09:24:03 2013  Koichi Sasada  <ko1@atdot.net>
+
+	* test/-ext-/postponed_job/test_postponed_job.rb: fix typo and class name.
+
+Mon May 27 09:05:17 2013  Koichi Sasada  <ko1@atdot.net>
+
+	* include/ruby/ruby.h, gc.c, vm_trace.c: add internal events.
+	  * RUBY_INTERNAL_EVENT_NEWOBJ: object created.
+	  * RUBY_INTERNAL_EVENT_FREE: object freed.
+	  * RUBY_INTERNAL_EVENT_GC_START: GC started.
+	  And rename `RUBY_EVENT_SWITCH' to `RUBY_INTERNAL_EVENT_SWITCH'.
+
+	  Internal events can not invoke any Ruby program because the tracing
+	  timing may be critical (under huge restriction).
+	  These events can be hooked only by C-extensions.
+	  We recommend to use rb_postponed_job_register() API to call Ruby
+	  program safely.
+
+	  This change is mostly written by Aman Gupta (tmm1).

+
+Mon May 27 06:22:41 2013  Koichi Sasada  <ko1@atdot.net>
+
+	* include/ruby/debug.h, vm_trace.c: add rb_postponed_job API.
+	  Postponed jobs are registered with this API. Registered jobs
+	  are invoked at `ruby-running-safe-point' as soon as possible.
+	  This timing is completely same as finalizer timing.
+
+	  There are two APIs:
+	  * rb_postponed_job_register(flags, func, data): register a
+	    postponed job with data. flags are reserved.
+	  * rb_postponed_job_register_one(flags, func, data): same as
+	    `rb_postponed_job_register', but only one `func' job is
+	    registered (skip if `func' is already registered).

+	  This change is mostly written by Aman Gupta (tmm1).
+	  https://bugs.ruby-lang.org/issues/8107#note-15

+
+	* gc.c (gc_stat): collect shade_operation_count,

+
+Mon May 27 01:15:22 2013  Koichi Sasada  <ko1@atdot.net>
+
+	* hash.c (rb_hash_tbl_raw), internal.h: added.

+
+	* include/ruby/intern.h: declare rb_hash_set_ifnone(hash, ifnone).

+
+	* proc.c (rb_method_entry_min_max_arity): fix missing break in switch.
+	  This was introduced in r38236, which is not intentional apparently.
+	  This has caused no actual harm because VM_METHOD_TYPE_OPTIMIZED is
+	  not used except for OPTIMIZED_METHOD_TYPE_SEND, but may do in

+
+Sat May 25 18:08:06 2013  Yusuke Endoh  <mame@tsg.ne.jp>

+

+Tue May 14 00:48:55 2013  Koichi Sasada  <ko1@atdot.net>
+
+	* include/ruby/ruby.h: constify RRational::(num,den) and

+
+Mon May 13 20:23:24 2013  NAKAMURA Usaku  <usa@ruby-lang.org>
+
+	* win32/win32.c, include/ruby/win32.h (getipaddrs): [experimental]
+	  emulate getipaddrs(3) on Unix.
+
+	* win32/Makefile.sub, configure.in (LIBS): need iphlpapi.lib for above
+	  function.
+
+	* include/ruby/win32.h (socketpair): rb_w32_socketpair() doesn't
+	  substitute for any function, so use non-prefixed name.

+	  This change is a part of RGENGC branch [ruby-trunk - Feature #8339].
+
+	* object.c: add new function rb_obj_reveal().
+	  This function reveal internal (hidden) object by rb_obj_hide().
+	  Note that do not change class before and after hiding.
+	  Only permitted example is:
+	    klass = RBASIC_CLASS(obj);
+	    rb_obj_hide(obj);
+	    ....
+	    rb_obj_reveal(obj, klass);
+
+	  TODO: API design. rb_obj_reveal() should be replaced with others.
+
+	  TODO: modify constified variables using cast may be harmful for
+	        compiler's analysis and optimization.
+	        Any idea to prohibit inserting RBasic::klass directly?
+	        If rename RBasic::klass and force to use RBASIC_CLASS(obj),
+	        then all codes such as `RBASIC(obj)->klass' will be
+	        compilation error. Is it acceptable? (We have similar

+	  operations that 1) release GVL 2) read 3) acquire gvl and
+	  (1) invoke context switch to main thread. and then, main
+	  thread's th.kill resume (1), but not (2). Thus read interrupt
+	  need TIME_QUANTUM_USEC. Then maximum iteration is 30sec/100msec

+                    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

+
+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.

+= NEWS for Ruby 2.1.0
+
+This document is a list of user visible feature changes made between
+releases except for bug fixes.
+
+Note that each entry is kept so brief that no reason behind or
+reference information is supplied with.  For a full list of changes
+with all sufficient information, see the ChangeLog file.
+
+== Changes since the 2.0.0 release
+
+=== Language changes
+
+* Now the default values of keyword arguments can be omitted.  Those
+  "required keyword arguments" need giving explicitly at the call time.

+* Added suffixes for integer and float literals: 'r', 'i', and 'ri'.
+  * "42r" and "3.14r" are evaluated as Rational(42, 1) and 3.14.rationalize,
+    respectively.  But exponential form with 'r' suffix like "6.022e+23r" is
+    not accepted because it is misleading.
+  * "42i" and "3.14i" are evaluated as Complex(0, 42) and Complex(0, 3.14),
+    respectively.
+  * "42ri" and "3.14ri" are evaluated as Complex(0, 42r) and Complex(0, 3.14r),
+    respectively.
+
+* def-expr now returns the symbol of its name instead of nil.

+    * RUBY_GC_MALLOC_LIMIT_GROWTH_FACTOR
+    * RUBY_GC_OLDMALLOC_LIMIT
+    * RUBY_GC_OLDMALLOC_LIMIT_MAX
+    * RUBY_GC_OLDMALLOC_LIMIT_GROWTH_FACTOR
+  * obsoleted environment variables:
+    * RUBY_FREE_MIN (Use RUBY_GC_HEAP_FREE_SLOTS instead)
+    * RUBY_HEAP_MIN_SLOTS (Use RUBY_GC_HEAP_INIT_SLOTS instead)
+
+* Integer
+  * New methods
+    * Fixnum#bit_length
+    * Bignum#bit_length
+  * Bignum performance improvement
+    * Use GMP if available.
+      GMP is used only for several operations:

+    * IO#seek supports SEEK_DATA and SEEK_HOLE as whence.
+    * IO#seek accepts symbols (:CUR, :END, :SET, :DATA, :HOLE) for 2nd argument.
+    * IO#read_nonblock accepts optional `exception: false` to return symbols
+    * IO#write_nonblock accepts optional `exception: false` to return symbols
+
+* Kernel
+  * New methods:
+    * Kernel#singleton_method
+
+* Module
+  * New methods:
+    * Module#using, which activates refinements of the specified module only
+      in the current class or module definition.
+    * Module#singleton_class? returns true if the receiver is a singleton class
+      or false if it is an ordinary class or module.
+  * extended methods:
+    * Module#refine is no longer experimental.
+    * Module#include and Module#prepend are now public methods.
+
+* Mutex
+  * misc
+    * Mutex#owned? is no longer experimental.
+
+* Numeric
+  * extended methods:
+    * Numeric#step allows the limit argument to be omitted, in which
+      case an infinite sequence of numbers is generated.  Keyword
+      arguments `to` and `by` are introduced for ease of use.
+
+* Process
+  * New methods:
+    * alternative methods to $0/$0=:
+      * Process.argv0() returns the original value of $0.

+      If you want to use this function with older Ruby,
+      consider to use string-scrub.gem.
+
+* Symbol
+  * All symbols are now frozen.
+
+* pack/unpack (Array/String)
+  * Q! and q! directives for long long type if platform has the type.
+
+* toplevel
+  * extended methods:
+    * main.using is no longer experimental. The method activates refinements
+      in the ancestors of the argument module to support refinement
+      inheritance by Module#include.
+
+=== Core classes compatibility issues (excluding feature bug fixes)
+
+* Dir
+  * incompatible changes:
+    * Dir#glob returns composed characters (previously Apple Modofied UTF-8).
+
+* Hash
+  * incompatible changes:
+    * Hash#reject will return plain Hash object in the future versions, that
+      is the original object's subclass, instance variables, default value,
+      and taintedness will be no longer copied, so now warnings are emitted
+      when called with such Hash.
+
+* IO
+  * incompatible changes:
+    * open ignore internal encoding if external encoding is ASCII-8BIT.
+
+* Kernel#eval, Kernel#instance_eval, and Module#module_eval.
+  * Copies the scope information of the original environment, which means
+    that private, protected, public, and module_function without arguments
+    do not affect the environment outside the eval string.
+    For example, `class Foo; eval "private"; def foo; end; end' doesn't make
+    Foo#foo private.
+
+* Kernel#untrusted?, untrust, and trust
+  * These methods are deprecated and their behavior is same as tainted?,
+    taint, and untaint, respectively.  If $VERBOSE is true, they show warnings.
+
+* Module#ancestors
+  * The ancestors of a singleton class now include singleton classes,
+    in particular itself.
+
+* Module#define_method and Object#define_singleton_method
+  * Now they return the symbols of the defined methods, not the methods/procs
+    themselves.
+
+* Numeric#quo
+  * Raises TypeError instead of ArgumentError if the receiver doesn't have
+    to_r method.
+
+* Proc
+  * Returning from lambda proc now always exits from the Proc, not from the
+    method where the lambda is created.  Returning from non-lambda proc exits
+    from the method, same as the former behavior.
+
+String
+  * If invalid: :replace is specified for String#encode, replace
+    invalid byte sequence even if the destination encoding equals to
+    the source encoding.
+
+=== Stdlib updates (outstanding ones only)
+
+* CGI::Util
+  * All class methods modulized.
+
+* Digest
+  * extended methods:
+    * Digest::Class.file takes optional arguments for its constructor
+
+* Matrix
+  * Added Vector#cross_product.
+
+* Net::SMTP
+  * Added Net::SMTP#rset to implement the RSET command
+
+* objspace
+  * new method:
+    * ObjectSpace.trace_object_allocations
+    * ObjectSpace.trace_object_allocations_start
+    * ObjectSpace.trace_object_allocations_stop
+    * ObjectSpace.trace_object_allocations_clear
+    * ObjectSpace.allocation_sourcefile

+    * ObjectSpace.allocation_class_path
+    * ObjectSpace.allocation_method_id
+    * ObjectSpace.allocation_generation
+    * ObjectSpace.reachable_objects_from_root
+    * ObjectSpace.dump
+    * ObjectSpace.dump_all
+
+* OpenSSL::BN
+  * extended methods:
+    * OpenSSL::BN.new allows Fixnum/Bignum argument.
+
+* open-uri
+  * Support multiple fields with same field name (like Set-Cookie).
+
+* Pathname
+  * New methods:
+    * Pathname#write
+    * Pathname#binwrite
+
+* rake
+  * Updated to 10.1.0.  Major changes include removal of the class namespace,
+    Rake::DSL to hold the rake DSL methods and removal of support for legacy
+    rake features.
+
+    For a complete list of changes since rake 0.9.6 see:
+
+    http://rake.rubyforge.org/doc/release_notes/rake-10_1_0_rdoc.html
+
+    http://rake.rubyforge.org/doc/release_notes/rake-10_0_3_rdoc.html
+
+* RbConfig
+  * New constants:
+    * RbConfig::SIZEOF is added to provide the size of C types.
+
+* RDoc
+  * Updated to 4.1.0.  Major enhancements include a modified default template
+  * and accessibility enhancements.
+
+    For a list of minor enhancements and bug fixes see:
+    https://github.com/rdoc/rdoc/blob/v4.1.0.preview.1/History.rdoc
+
+* Resolv
+  * New methods:
+    * Resolv::DNS.fetch_resource
+  * One-shot multicast DNS support
+  * Support LOC resources
+
+* REXML::Parsers::SAX2Parser
+  * Fixes wrong number of arguments of entitydecl event. Document of the event
+    says "an array of the entity declaration" but implementation passes two
+    or more arguments. It is an implementation bug but it breaks backward
+    compatibility.
+
+* REXML::Parsers::StreamParser
+  * Supports "entity" event.
+
+* REXML::Text
+  * REXML::Text#<< supports method chain like 'text << "XXX" << "YYY"'.
+  * REXML::Text#<< supports not "raw" mode.
+
+* Rinda::RingServer, Rinda::RingFinger
+  * Rinda now supports multicast sockets.  See Rinda::RingServer and
+    Rinda::RingFinger for details.
+
+* RubyGems
+  * Updated to 2.2.0.  Notable new features include:
+
+    * Gemfile or gem.deps.rb support including Gem.file.lock (experimental)
+    * Improved, iterative resolver (compared to RubyGems 2.1 and earlier)
+    * Support for a sharing a GEM_HOME across ruby platforms and versions
+
+  * Updated to 2.2.2.  Fixes some minor bugs and performance regressions.
+
+    For a complete list of enhancements and bug fixes see:
+    https://github.com/rubygems/rubygems/tree/master/History.txt
+
+* Set
+  * New methods:
+    * Set#intersect?
+    * Set#disjoint?
+
+* Socket
+  * New methods:
+    * Socket.getifaddrs
+
+* StringScanner
+  * extended methods:
+    * StringScanner#[] supports named captures.
+
+* Syslog::Logger
+  * Added facility.
+
+* Tempfile
+  * New methods:
+    * Tempfile.create
+
+* Timeout
+  * The exception to terminate the given block can no longer be rescued
+    inside the block, by default, unless the exception class is given
+    explicitly.
+
+* TSort
+  * New methods:
+    * TSort.tsort
+    * TSort.tsort_each
+    * TSort.strongly_connected_components
+    * TSort.each_strongly_connected_component
+    * TSort.each_strongly_connected_component_from
+
+* WEBrick
+  * The body of a response may now be a StringIO or other IO-like that responds
+    to #readpartial and #read.
+
+* XMLRPC::Client
+  * New methods:
+    * XMLRPC::Client#http. It returns Net::HTTP for the client. Normally,
+      it is not needed. It is useful when you want to change minor HTTP client
+      options. You can change major HTTP client options by XMLRPC::Client
+      methods. You should use XMLRPC::Client methods for changing major
+      HTTP client options instead of XMLRPC::Client#http.
+
+=== Stdlib compatibility issues (excluding feature bug fixes)
+
+* Set
+  * incompatible changes:
+    * Set#to_set now returns self instead of generating a copy.
+
+* URI
+  * incompatible changes:
+    * URI.decode_www_form follows current WHATWG URL Standard.
+      It gets encoding argument to specify the character encoding.
+      It now allows loose percent encoded strings, but denies ;-separator.
+    * URI.encode_www_form follows current WHATWG URL Standard.
+      It gets encoding argument to convert before percent encode.
+      UTF-16 strings aren't converted to UTF-8 before percent encode by default.
+
+* curses
+  * Removed.
+    curses is now available as a gem.
+    See https://rubygems.org/gems/curses for details.
+
+=== Built-in global variables compatibility issues
+
+* $SAFE
+  * $SAFE=4 is obsolete.  If $SAFE is set to 4 or larger, an ArgumentError
+    is raised.
+
+=== C API updates
+
+* rb_gc_set_params() is deprecated. This is only used in Ruby internal.
+
+* rb_gc_count() added. This returns the number of times GC occurred.
+
+* rb_gc_stat() added. This allows access to specific GC.stat() values from C
+  without any allocation overhead.
+
+* rb_gc_latest_gc_info() added. This allows access to GC.latest_gc_info().
+
+* rb_postponed_job_register() added. Takes a function callback which is invoked
+  when the VM is in a consistent state, i.e. to perform work from a C signal
+  handler.
+
+* rb_profile_frames() added. Provides low-cost access to the current ruby stack
+  for callstack profiling.
+
+* rb_tracepoint_new() supports new internal events accessible only from C:
+  * RUBY_INTERNAL_EVENT_NEWOBJ
+  * RUBY_INTERNAL_EVENT_FREEOBJ
+  * RUBY_INTERNAL_EVENT_GC_START
+  * RUBY_INTERNAL_EVENT_GC_END_MARK
+  * RUBY_INTERNAL_EVENT_GC_END_SWEEP
+  * Note that you *can not* specify "internal events" with normal events
+    (such as RUBY_EVENT_CALL, RUBY_EVENT_RETURN) simultaneously.

 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.

-You can redistribute it and/or modify it under either the terms of the GPL
-(see COPYING file), or the conditions below:
+1.   If +./configure+ does not exist or is older than configure.in,
+     run autoconf to (re)generate configure.
 
-  1. You may make and give away verbatim copies of the source form of the
-     software without restriction, provided that you duplicate all of the
-     original copyright notices and associated disclaimers.
+2.   Run +./configure+, which will generate config.h and Makefile.
 
-  2. You may modify your copy of the software in any way, provided that
-     you do at least ONE of the following:
+     Some C compiler flags may be added by default depending on your
+     environment.  Specify <tt>optflags=..</tt> and <tt>warnflags=..</tt> as
+     necessary to override them.
 
-       a) place your modifications in the Public Domain or otherwise
-          make them Freely Available, such as by posting said
-	  modifications to Usenet or an equivalent medium, or by allowing
-	  the author to include your modifications in the software.
+3.   Edit +defines.h+ if you need. Usually this step will not be needed.
 
-       b) use the modified software only within your corporation or
-          organization.
+4.   Remove comment mark(<tt>#</tt>) before the module names from +ext/Setup+
+     (or add module names if not present), if you want to link modules
+     statically.
 
-       c) rename any non-standard executables so the names do not conflict
-	  with standard executables, which must also be provided.
+     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 "<tt>#option nodynamic</tt>" in

-       d) make other distribution arrangements with the author.
+     Usually this step will not be needed.
 
-  3. You may distribute the software in object code or executable
-     form, provided that you do at least ONE of the following:
+5.   Run +make+.
 
-       a) distribute the executables and library files of the software,
-	  together with instructions (in the manual page or equivalent)
-	  on where to get the original distribution.
+6.   Optionally, run '<tt>make check</tt>' to check whether the compiled Ruby
+     interpreter works well. If you see the message "<tt>check succeeded</tt>",
+     your ruby works as it should (hopefully).
 
-       b) accompany the distribution with the machine-readable source of
-	  the software.
+7.   Run '<tt>make install</tt>'
+
+     This command will create following directories and install files
+     onto them.
+
+     * <tt>${DESTDIR}${prefix}/bin</tt>

-     files under the ./missing directory.  See each file for the copying
-     condition.
+Some extension libraries may not get compiled because of lack of
+necessary external libraries and/or headers, then you will need to run

 In C, variables have types and data do not have types.  In contrast,
-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
-
-Otherwise, there are several other types used internally:
-
-	T_ICLASS
-	T_MATCH
-	T_VARMAP
-	T_SCOPE
-	T_NODE
+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
 
 Most of the types are represented by C structures.

-The data for type T_NIL, T_FALSE, T_TRUE are nil, true, false
+The data for type T_NIL, T_FALSE, T_TRUE are nil, false, true
 respectively.  They are singletons for the data type.
-
-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.
+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 is depend 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 includes a type check,
+so an exception will be raised if the conversion failed.  NUM2DBL()
+can be used to retrieve the double float value in 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 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.
 
 Other data types have corresponding C structures, e.g. struct RArray
-for T_ARRAY etc.  VALUE of the type which has corresponding structure
-can be cast to retrieve the pointer to the struct.  The casting macro
-RXXXX for each data type like RARRAY(obj).  see "ruby.h".
-
-For example, `RSTRING(size)->len' is the way to get the size of the
-Ruby String object.  The allocated region can be accessed by
-`RSTRING(str)->ptr'.  For arrays, `RARRAY(ary)->len' and
-`RARRAY(ary)->ptr' respectively.
+for T_ARRAY etc. The VALUE of the type which has the corresponding

+instance, RARRAY(obj).  See "ruby.h".  However, we do not recommend
+to access RXXXX data directly because these data structure is complex.
+Use corresponding rb_xxx() functions to access internal struct.
+For example, to access an entry of array, use rb_ary_entry(ary, offset)
+and rb_ary_store(ary, offset, obj).

+`RSTRING_LEN(str)' to get the size of the Ruby String object.  The

- void rb_warning(char *fmt, ...)
+Generally, the use of the technique called write barriers is required in

+== Write barriers
 
- void ruby_init()
+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.
 
-Initializes the interpreter.
+=== Don't touch pointers directly
 
- void ruby_options(int argc, char **argv)
+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.
 
-Process command line arguments for the interpreter.
+DO NOT USE THESE MACROS and instead use the corresponding C-APIs such as
+rb_ary_aref(), rb_ary_store() and so on.
 
- void ruby_run()
+=== Consider whether to insert write barriers
 
-Starts execution of the interpreter.
+You don't need to care about write barriers if you only use built-in
+types.
 
- void ruby_script(char *name)
+If you support T_DATA objects, you may consider using write barriers.
 
-Specifies the name of the script ($0).
+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.
 
-Appendix B. Functions Available in extconf.rb
+(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.
 
-These functions are available in extconf.rb:
+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.

+=== Combine with built-in types
 
-Checks whether library which contains specified function exists.
-Returns true if the library exists.
+Please consider utilizing built-in types. Most built-in types support
+write barrier, so you can use them to avoid manually inserting write
+barriers.
 
- have_func(func)
+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.
 
-Checks whether func exists.  Returns true if the function exists.  To
-check functions in the additional library, you need to check that
-library first using have_library().
+With use of such techniques, you don't need to insert write barriers
+anymore.
 
- have_header(header)
+=== Insert write barriers
 
-Checks for the header files.  Returns true if the header file exists.
+[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.
 
- create_makefile(target)
+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.
 
-Generates the Makefile for the extension library.  If you don't invoke
-this method, the compilation will not be done.
+For a complete guide for RGenGC and write barriers, please refer to
+<https://bugs.ruby-lang.org/projects/ruby-trunk/wiki/RGenGC>.

+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
+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_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: %iはObject#to_s('+'フラグが指定されているときはObject#inspect)を
+  使ったVALUEの出力に使用されているため，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)
+
+  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)
+
+  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strに追加する．この関数の機能は，それぞれ
+  rb_str_cat2(str, rb_sprintf(format, ...)) や
+  rb_str_cat2(str, rb_vsprintf(format, ap)) と同等である．
+
+rb_enc_str_new(const char *ptr, long len, rb_encoding *enc)
+rb_enc_str_new_cstr(const char *ptr, rb_encoding *enc)
+
+  指定されたエンコーディングでRubyの文字列を生成する.
+
+rb_usascii_str_new(const char *ptr, long len)
+rb_usascii_str_new_cstr(const char *ptr)
+
+  エンコーディングがUS-ASCIIのRubyの文字列を生成する.
+
+rb_str_resize(VALUE str, long len)
+
+  Rubyの文字列のサイズをlenバイトに変更する．strの長さは前
+  以てセットされていなければならない．lenが元の長さよりも短
+  い時は，lenバイトを越えた部分の内容は捨てられる．lenが元
+  の長さよりも長い時は，元の長さを越えた部分の内容は保存さ
+  れないでゴミになるだろう．この関数の呼び出しによって
+  RSTRING_PTR(str)が変更されるかもしれないことに注意．
+
+rb_str_set_len(VALUE str, long len)
+
+  Rubyの文字列のサイズをlenバイトにセットする．strが変更可
+  能でなければ例外が発生する．RSTRING_LEN(str)とは無関係に，
+  lenバイトまでの内容は保存される．lenはstrの容量を越えてい
+  てはならない．
+
+
+== 配列に対する関数
+
+rb_ary_new()
+
+  要素が0の配列を生成する．
+
+rb_ary_new2(long len)
+rb_ary_new_capa(long len)
+
+  要素が0の配列を生成する．len要素分の領域をあらかじめ割り
+  当てておく．
+
+rb_ary_new3(long n, ...)
+rb_ary_new_from_args(long n, ...)
+
+  引数で指定したn要素を含む配列を生成する．
+
+rb_ary_new4(long n, VALUE *elts)
+rb_ary_new_from_values(long n, VALUE *elts)
+
+  配列で与えたn要素の配列を生成する．
+
+rb_ary_to_ary(VALUE obj)
+
+  オブジェクトを配列に変換する.
+  Object#to_aryと同等である.
+
+他にも配列を操作する関数が多数ある. これらは
+引数aryに配列を渡さなければならない. さもないと
+コアを吐く.
+
+rb_ary_aref(argc, VALUE *argv, VALUE ary)
+
+  Array#[]と同等.
+
+rb_ary_entry(VALUE ary, long offset)
+
+  ary[offset]
+
+rb_ary_store(VALUE ary, long offset, VALUE obj) ::
+
+  ary[offset] = obj
+
+rb_ary_subseq(VALUE ary, long beg, long len)
+
+  ary[beg, len]
+
+rb_ary_push(VALUE ary, VALUE val)
+rb_ary_pop(VALUE ary)
+rb_ary_shift(VALUE ary)
+rb_ary_unshift(VALUE ary, VALUE val)
+
+rb_ary_cat(VALUE ary, const VALUE *ptr, long len)
+
+  配列aryにptrからlen個のオブジェクトを追加する．
+
+= 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．
+
+=== 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．
+
+=== 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 */
+      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) {\
+      Data_Get_Struct(obj, struct dbmdata, dbmp);\
+      if (dbmp->di_dbm == 0) closed_dbm();\
+  }
+
+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
+述されたプログラムがあり，Rubyライブラリに置きたい場合には，
+拡張ライブラリ用のディレクトリの下に lib というディレクトリ
+を作り，そこに 拡張子 .rb のファイルを置いておけば同時にイン
+ストールされます．
+
+== デバッグ
+
+まあ，デバッグしないと動かないでしょうね．ext/Setupにディレ
+クトリ名を書くと静的にリンクするのでデバッガが使えるようにな
+ります．その分コンパイルが遅くなりますけど．
+
+== できあがり
+
+後はこっそり使うなり，広く公開するなり，売るなり，ご自由にお
+使いください．Rubyの作者は拡張ライブラリに関して一切の権利を
+主張しません．

+= 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は最初から純粋なオブジェクト指向言語として設計されていま
+すから，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．もちろん通常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
+
+== 入手法
+
+=== FTPで
+
+以下の場所においてあります．
+
+ftp://ftp.ruby-lang.org/pub/ruby/
+
+=== Subversionで
+
+開発先端のソースコードは次のコマンドで取得できます．
+
+  $ svn co http://svn.ruby-lang.org/repos/ruby/trunk/ ruby
+
+他に開発中のブランチの一覧は次のコマンドで見られます．
+
+  $ svn ls http://svn.ruby-lang.org/repos/ruby/branches/
+
+=== Gitで
+
+SubversionのミラーをGitHubに公開しています．
+以下のコマンドでリポジトリを取得できます．
+
+  $ git clone git://github.com/ruby/ruby.git
+
+== 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-ctl@ruby-lang.org
+
+まで本文に
+
+   subscribe YourFirstName YourFamilyName
+
+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-ctl@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 <tt>optflags=..</tt> <tt>warnflags=..</tt> 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「<tt>option nodynamic</tt>」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.   <tt>make check</tt>でテストを行う．
+
+     「<tt>check succeeded</tt>」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.   <tt>make install</tt>
+
+     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．
+
+     * <tt>${DESTDIR}${prefix}/bin</tt>
+     * <tt>${DESTDIR}${prefix}/include/ruby-${MAJOR}.${MINOR}.${TEENY}</tt>
+     * <tt>${DESTDIR}${prefix}/include/ruby-${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}</tt>
+     * <tt>${DESTDIR}${prefix}/lib</tt>
+     * <tt>${DESTDIR}${prefix}/lib/ruby</tt>
+     * <tt>${DESTDIR}${prefix}/lib/ruby/${MAJOR}.${MINOR}.${TEENY}</tt>
+     * <tt>${DESTDIR}${prefix}/lib/ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}</tt>
+     * <tt>${DESTDIR}${prefix}/lib/ruby/site_ruby</tt>
+     * <tt>${DESTDIR}${prefix}/lib/ruby/site_ruby/${MAJOR}.${MINOR}.${TEENY}</tt>
+     * <tt>${DESTDIR}${prefix}/lib/ruby/site_ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}</tt>
+     * <tt>${DESTDIR}${prefix}/lib/ruby/vendor_ruby</tt>
+     * <tt>${DESTDIR}${prefix}/lib/ruby/vendor_ruby/${MAJOR}.${MINOR}.${TEENY}</tt>
+     * <tt>${DESTDIR}${prefix}/lib/ruby/vendor_ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}</tt>
+     * <tt>${DESTDIR}${prefix}/lib/ruby/gems/${MAJOR}.${MINOR}.${TEENY}</tt>
+     * <tt>${DESTDIR}${prefix}/share/man/man1</tt>
+     * <tt>${DESTDIR}${prefix}/share/ri/${MAJOR}.${MINOR}.${TEENY}/system</tt>
+
+     RubyのAPIバージョンが'_x.y.z_'であれば，<tt>${MAJOR}</tt>は
+     '_x_'で，<tt>${MINOR}</tt>は'_y_'，<tt>${TEENY}</tt>は'_z_'です．
+
+     <b>注意</b>: 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く
+だ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(あるに違いない)，作者にその
+ことをレポートすれば，解決できるかも知れません．
+
+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<tt>setjmp()</tt>または<tt>getcontext()</tt>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．<tt>defined(\_\_mc68000\_\_)</tt>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知
+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．

-
-* compile time string concatenation, "hello" "world" => "helloworld"
-* ../... outside condition invokes operator method too.
-* %w(a\ b\ c abc) => ["a b c", "abc"]
-* package or access control for global variables
-* class variable (prefix?)
-* named arguments like foo(nation:="german") or foo(nation: "german").
-* method to retrieve argument information (need new C API)
-* multiple return values, yield values.  maybe incompatible ???
-* cascading method invocation ???
-* def Class#method .. end ??
-* class Foo::Bar<Baz .. end, module Boo::Bar .. end
-* def Foo::Bar::baz() .. end ??
-
-Hacking Interpreter
-
-* hash[key] = nil may not remove entry; hashes may have nil as the value.
-* RUBYOPT environment variable
-* non-blocking open (e.g. named pipe) for thread
-* avoid blocking with gethostbyname/gethostbyaddr
-* objectify interpreters
-* remove rb_eval() recursions
-* syntax tree -> bytecode ???
-* scrambled script, or script filter
-* setuid ruby

-* method to detect non-number trailer for to_i/to_f.
-* Stream or Port, abstract superclass of IO ?
-* String#{pred,prev}, String#downto
-* optional stepsize argument for succ()
-* Dir.glob(pat){|f|...}
