-	* ext/digest, test/digest/test_digest.rb: Merge from trunk:
-	  - Introduce versioning in Digest::Base API, and prefix C
-	    constants with RUBY_ and C type names with rb_ to avoid name
-	    clash in writing extensions.
-	  - Introduce Digest::Class and Digest::Instance for ease of
-	    implementing subclasses and add-ons.
-	  - Digest::Instance module requires and assumes that any instance
-	    be resettable and clonable.  An instance method #new() is
-	    added so digest instances work just like digest classes.
-	  - The constructor does no longer take an initial string to feed;
-	    digest() and hexdigest() now do, instead.  This allows digest
-	    classes to take their own hashing parameters.
-	  - Make some changes to digest() and hexdigest() class methods,
-	    which now take extra arguments, which are passed through to
-	    the constructor in an internal call.
-	  - Add #digest_length/size/length() and #block_length(),
-	  - Add the Digest::SHA2 class to wrap up SHA2 variants: SHA256,
-	    SHA384 and SHA512, hoping this module would make a decent
-	    example of a digest subclass written in Ruby.
-	  - Rip BubbleBabble support out of the base class and have a
-	    separate module named digest/bubblebabble.
-	  - Remove RD documents in favor of newly written and embedded
-	    RDoc documentation.
+	* ext/psych/lib/psych/visitors/to_ruby.rb: process merge keys before

-Sun Oct 22 16:47:56 2006  Nobuyoshi Nakada  <nobu@ruby-lang.org>
+	* 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.
 
-	* string.c (rb_str_substr): should be infected with only original
-	  string, but not the shared string.  fixed: [ruby-core:09152]
+	  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'.
 
-	* string.c (rb_str_new4): keep shared string untainted when orignal
-	  string is tainted.  fixed: [ruby-dev:29672]
+	  To implement this feature, move memsize_of() function from
+	  ext/objspace/objspace.c and expose rb_obj_memsize_of().
 
-Sun Oct 22 05:20:34 2006  URABE Shyouhei  <shyouhei@ice.uec.ac.jp>
+	  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.
 
-	* configure.in: alloca is broken; use C_ALLOCA instead.
-	  [ruby-dev:29416]
+	  The macro RGENGC_ESTIMATE_OLDSPACE enables/disables this feature,
+	  and turned off as default.
 
-Fri Oct 20 10:47:43 2006  NAKAMURA Usaku  <usa@ruby-lang.org>
+	  We need to compare 3gen GC and this feature carefully.
+	  (it is possible to enable both feature)
+	  We need a help to compare them.
 
-	* lib/mkmf.rb: fixed the bug of handling COMMON_MACROS.
+	* internal.h: expose rb_obj_memsize_of().
 
-Fri Oct 20 08:42:38 2006  Nobuyoshi Nakada  <nobu@ruby-lang.org>
+	* ext/objspace/objspace.c: use rb_obj_memsize_of() function.
 
-	* common.mk (NULLCMD): dummy command.
+	* cont.c (fiber_memsize): fix to check NULL.
 
-	* bcc32/Makefile.sub (post-install-*): Borland make cannot ignore
-	  command-less double-colon rules.  [ruby-dev:29676]

+Tue Nov  5 04:03:07 2013  Koichi Sasada  <ko1@atdot.net>
 
-	* ext/extmk.rb: workaround for Borland make.
+	* gc.c (GC_MALLOC_LIMIT_MAX): fix default value 512MB -> 384MB.
+	  512MB is huge.

-	* array.c (rb_ary_shift): shorten copy size.  fixed: [ruby-list:42907]
+	* gc.c: add 3gen GC patch, but disabled as default.
 
-	* signal.c (Init_signal): handle SIGTERM.  fixed: [ruby-list:42895]
+	  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.
 
-	* win32/win32.c (rb_w32_utime): allow NULL to set the current time.
-	  [ruby-talk:219248]
+	  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.
 
-Wed Oct 18 00:55:33 2006  Nobuyoshi Nakada  <nobu@ruby-lang.org>
+	  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.
 
-	* parse.y (parser_yylex): use particular enums.  [ruby-core:09221]
+	  To solve this problem, generational GC with more generations
+	  technique is known. This patch implements three generations gen GC.
 
-Mon Oct 16 08:30:43 2006  Nobuyoshi Nakada  <nobu@ruby-lang.org>
+	  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.
 
-	* mkconfig.rb: *OBJS are not needed for extension libraries.
+	  Representation of generations:
+	  * Infant: !FL_PROMOTED and !oldgen_bitmap [00]
+	  * Young :  FL_PROMOTED and !oldgen_bitmap [10]
+	  * Old   :  FL_PROMOTED and  oldgen_bitmap [11]
 
-	* {bcc32,wince,win32}/Makefile.sub (config.status): fixed typo,
-	  missing comma.
+	  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.
 
-Sun Oct 15 01:03:08 2006  Nobuyoshi Nakada  <nobu@ruby-lang.org>
+	  To evaluate this feature on more applications, I commit this patch.
+	  Reports are very welcome.

-
-	* lib/logger.rb: leading 0 padding of timestamp usec part.
-
-	* lib/csv.rb (CSV.parse): [CAUTION] behavior changed.  in the past,
-	  CSV.parse accepts a filename to be read-opened (it was just a
-	  shortcut of CSV.open(filename, 'r')).  now CSV.parse accepts a
-	  string or a stream to be parsed e.g.
-	  CSV.parse("1,2\n3,r") #=> [['1', '2'], ['3', '4']]
-
-	* lib/csv.rb: CSV::Row and CSV::Cell are deprecated.  these classes
-	  are removed in the future.  in the new csv.rb, row is represented
-	  as just an Array.  since CSV::Row was a subclass of Array, it won't
-	  hurt almost all programs except one which depended CSV::Row#match.
-	  and a cell is represented as just a String or nil(NULL).  this
-	  change will cause widespread destruction.
-
-	      CSV.open("foo.csv", "r") do |row|
-		row.each do |cell|
-		  if cell.is_null       # using Cell#is_null
-		    p "(NULL)"
-		  else
-		    p cell.data         # using Cell#data
-		  end
-		end
-	      end
-
-	    must be just;
-
-	      CSV.open("foo.csv", "r") do |row|
-		row.each do |cell|
-		  if cell.nil?
-		    p "(NULL)"
-		  else
-		    p cell
-		  end
-		end
-	      end
-
-	* lib/csv.rb: [CAUTION] record separator(CR, LF, CR+LF) behavior
-	  change.  CSV.open, CSV.parse, and CSV,generate now do not force
-	  opened file binmode.  formerly it set binmode explicitly.
-
-	  with CSV.open, binmode of opened file depends the given mode
-	  parameter "r", "w", "rb", and "wb".  CSV.parse and CSV.generate open
-	  file with "r" and "w".
-
-	  setting mode properly is user's responsibility now.
-
-	* lib/csv.rb: accepts String as a fs (field separator/column separator)
-	  and rs (record separator/row separator)
-
-	* lib/csv.rb (CSV.read, CSV.readlines): added.  works as IO.read and
-	  IO.readlines in CSV format.
-
-	* lib/csv.rb: added CSV.foreach(path, rs = nil, &block).  CSV.foreach
-	  now does not handle "| cmd" as a path different from IO.foreach.

-Thu Oct  9 12:05:46 2003  Eric Sunshine  <sunshine@sunshineco.com>
+	* thread_pthread.c (timer_thread_sleep): adjust the above changes.
 
-	* configure.in: revived NextStep, OpenStep, and Rhapsody ports which
-	  had become unbuildable; enhanced --enable-fat-binary option so that
-	  it accepts a list of desired architectures (rather than assuming a
-	  fixed list), or defaults to a platform-appropriate list if user does
-	  not provide an explicit list; made the default list of architectures
-	  for MAB (fat binary) more comprehensive; now uses -fno-common even
-	  when building the interpreter (in addition to using it for
-	  extensions), thus allowing the interpreter to be embedded into a
-	  plugin module of an external project (in addition to allowing
-	  embedding directly into an application); added checks for
-	  <netinet/in_systm.h> (needed by `socket' extension) and getcwd(); now
-	  ensures that -I/usr/local/include is employed when extensions'
-	  extconf.rb scripts invoke have_header() since extension checks on
-	  NextStep and OpenStep will fail without it if the desired resource
-	  resides in the /usr/local tree; fixed formatting of --help message.
+	* thread_pthread.c (setup_communication_pipe_internal): factor
+	  out pipe initialize logic.
 
-	* Makefile.in: $(LIBRUBY_A) rule now deletes the archive before
-	  invoking $(AR) since `ar' on Apple/NeXT can not "update" MAB archives
-	  (see configure's --enable-fat-binary option); added rule for new
-	  missing/getcwd.c.
+Wed Mar  6 22:56:14 2013  KOSAKI Motohiro  <kosaki.motohiro@gmail.com>
 
-	* defines.h: fixed endian handling during MAB build (see configure's
-	  --enable-fat-binary option) to ensure that all portions of the
-	  project see the correct WORDS_BIGENDIAN value (some extension modules
-	  were getting the wrong endian setting); added missing constants
-	  GETPGRP_VOID, WNOHANG, WUNTRACED, X_OK, and type pid_t for NextStep
-	  and OpenStep; removed unnecessary and problematic HAVE_SYS_WAIT_H
-	  define in NeXT section.
+	* thread_pthread.c (ubf_select): add to small comments why we
+	  need to call rb_thread_wakeup_timer_thread().
 
-	* dir.c: do not allow NAMLEN() macro to trust dirent::d_namlen on
-	  NextStep since, on some installations, this value always resolves
-	  uselessly to zero.
+Wed Mar  6 21:42:24 2013  KOSAKI Motohiro  <kosaki.motohiro@gmail.com>
 
-	* dln.c: added error reporting to NextStep extension loader since the
-	  previous behavior of failing silently was not useful; now ensures
-	  that NSLINKMODULE_OPTION_BINDNOW compatibility constant is defined
-	  for OpenStep and Rhapsody; no longer includes <mach-o/dyld.h> twice
-	  on Rhapsody since this header lacks multiple-include protection,
-	  which resulted in "redefinition" compilation errors.
+	* thread_pthread.c (rb_thread_create_timer_thread): factor out
+	  creating communication pipe logic into separate function.
+	* thread_pthread.c (setup_communication_pipe): new helper function.
+	* thread_pthread.c (set_nonblock): moves a definition before
+	  setup_communication_pipe.
 
-	* main.c: also create hard reference to objc_msgSend() on NeXT
-	  platforms (in addition to Apple platforms).
+Sun Mar  3 02:42:29 2013  KOSAKI Motohiro  <kosaki.motohiro@gmail.com>
 
-	* lib/mkmf.rb: now exports XCFLAGS from configure script to extension
-	  makefiles so that extensions can be built MAB (see configure's
-	  --enable-fat-binary option); also utilize XCFLAGS in cc_command()
-	  (but not cpp_command() because MAB flags are incompatible with
-	  direct invocation of `cpp').
+	* thread_pthread.c (consume_communication_pipe): retry when
+	  read returned CCP_READ_BUFF_SIZE.
 
-	* ext/curses/extconf.rb: now additionally checks for presence of these
-	  curses functions which are not present on NextStep or Openstep:
-	  bkgd(), bkgdset(), color(), curs(), getbkgd(), init(), scrl(), set(),
-	  setscrreg(), wattroff(), wattron(), wattrset(), wbkgd(), wbkgdset(),
-	  wscrl(), wsetscrreg()
+Wed Mar  6 21:31:35 2013  KOSAKI Motohiro  <kosaki.motohiro@gmail.com>
 
-	* ext/curses/curses.c: added appropriate #ifdef's for additional set of
-	  curses functions now checked by extconf.rb; fixed curses_bkgd() and
-	  window_bkgd() to correctly return boolean result rather than numeric
-	  result; fixed window_getbkgd() to correctly signal an error by
-	  returning nil rather than -1.
+	* thread_pthread.c (timer_thread_sleep): use poll() instead of
+	  select(). select doesn't work if timer_thread_pipe[0] is
+	  greater than FD_SETSIZE.
+	* thread_pthread.c (USE_SLEEPY_TIMER_THREAD): add a dependency
+	  against poll.
 
-	* ext/etc/etc.c: setup_passwd() and setup_group() now check for null
-	  pointers before invoking rb_tainted_str_new2() upon fields extracted
-	  from `struct passwd' and `struct group' since null pointers in some
-	  fields are common on NextStep/OpenStep (especially so for the
-	  `pw_comment' field) and rb_tainted_str_new2() throws an exception
-	  when it receives a null pointer.

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

+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 with Ruby 1.8.5
-
-=== New platforms/build tools support
-
-* IA64 HP-UX
-
-* Visual C++ 8 SP1
-
-* autoconf 2.6x
-
-=== Library updates (outstanding ones only)

-* date
-
-  * Updated based on date2 4.0.3.
-
-* digest
-
-  * New internal APIs for C and Ruby.
-
-  * Support for autoloading.
-
-  * See below for new features and compatibility issues.
-
-* nkf
-
-  * Updated based on nkf as of 2007-01-28.
-
-* tk
-
-  * Tk::X_Scrollable (Y_Scrollable) is renamed to Tk::XScrollable
-    (YScrollable). Tk::X_Scrollable (Y_Scrollable) is still available,
-    but it is an alias name.
-
-  * Updated Tile extension support based on Tile 0.7.8.
-
-  * Support --without-X11 configure option for non-X11 versions of
-    Tcl/Tk (e.g. Tcl/Tk Aqua).
-
-  * New sample script: irbtkw.rbw -- IRB on Ruby/Tk. It has no trouble
-    about STDIN blocking on Windows.
-
-=== New methods and features
-
-* builtin classes
-
-  * New method: Kernel#instance_variable_defined?
-
-  * New method: Module#class_variable_defined?
-
-  * New feature: Dir::glob() can now take an array of glob patterns.
-
-* digest
-
-  * New digest class methods: file
-
-  * New digest instance methods: clone, reset, new,
-    inspect, digest_length (alias size or length),
-    block_length()
-
-  * New library: digest/bubblebabble
-
-  * New function: Digest(name)
-
-* fileutils
-
-  * New option for FileUtils.cp_r(): :remove_destination

-
-  * New method: WEBrick::Cookie.parse_set_cookies()
-
-=== Compatibility issues (excluding feature bug fixes)
-
-* builtin classes
-
-  * String#intern now raises SecurityError when $SAFE level is greater
-    than zero.
-
-* fileutils
-
-  * A minor implementation change breaks Rake <=0.7.1.
-    Updating Rake to 0.7.2 fixes the problem.
-
-* digest
-
-  * The constructor does no longer take an initial
-    string to feed; digest() and hexdigest() now do,
-    instead.  The following examples show how to
-    migrate:
-
-      # Before
-      md = Digest::MD5.new("string")
-      # After (works with any version)
-      md = Digest::MD5.new.update("string")
-        
-      # Before
-      hd = Digest::MD5.new("string").hexdigest
-      # After (works with any version)
-      hd = Digest::MD5.hexdigest("string")
+== 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.
+
+=== Core classes updates (outstanding ones only)
+
+* Array
+  * New methods
+    * Array#to_h converts an array of key-value pairs into a Hash.
+
+* Binding
+  * New methods
+    * Binding#local_variable_get(symbol)
+    * Binding#local_variable_set(symbol, obj)
+    * Binding#local_variable_defined?(symbol)
+
+* Enumerable
+  * New methods
+    * Enumerable#to_h converts a list of key-value pairs into a Hash.
+
+* Exception
+  * New methods
+    * Exception#cause provides the previous exception which has been caught
+      at where raising the new exception.
+
+* GC
+  * added environment variable:
+    * RUBY_HEAP_SLOTS_GROWTH_FACTOR: growth rate of the heap.
+
+* Integer
+  * New methods
+    * Fixnum#bit_length
+    * Bignum#bit_length
+  * Bignum performance improvement
+    * Use GMP if available.
+      GMP is used only for several operations:
+      multiplication, division, radix conversion, GCD
+
+* IO
+  * extended methods:
+    * 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.
+      * Process.setproctitle() sets the process title without affecting $0.
+    * Process.clock_gettime
+    * Process.clock_getres
+
+* RbConfig
+  * New constants:
+    * RbConfig::SIZEOF is added to provide the size of C types.
+
+* String
+  * New methods:
+    * String#scrub and String#scrub! verify and fix invalid byte sequence.
+  * extended methods:
+    * If invalid: :replace is specified for String#encode, replace
+      invalid byte sequence even if the destination encoding equals to
+      the source encoding.
+
+* 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)
+
+* 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.
+
+=== 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_sourceline
+    * ObjectSpace.allocation_class_path
+    * ObjectSpace.allocation_method_id
+    * ObjectSpace.allocation_generation
+    * ObjectSpace.reachable_objects_from_root
+
+* 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
+
+* RDoc
+  * Updated to 4.1.0.preview.2.  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 backword
+    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.preview.2  For a list of enhancements and bug fixes see:
+    https://github.com/rubygems/rubygems/blob/v2.2.0.preview.1/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.
+
+=== 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

+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
+representation of var.  These macros will skip the replacement if var

 argument, to change the value of var in place.
 
-In version 1.6 or earlier, STR2CSTR() was used to do the same thing

-of a dangling pointer problem in the to_str() impliclit conversion.
+You can also use the macro named StringValueCStr(). This is just

+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

+31bitに，longのサイズが64bitのプラットフォームであれば63bit

+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．

+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Enumerate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)

+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．

-- Class#allocate - basicNew
-- class Foo::Bar<Baz .. end, module Boo::Bar .. end
-* operator !! for rescue. ???
-* objectify characters
-* ../... outside condition invokes operator method too.
-* ... inside condition turns off just before right condition.???
-* package or access control for global variables??
-* named arguments like foo(nation:="german") or foo(nation: "german").
-* method to retrieve argument information (needs new C API)
-* multiple return values, yield values.  maybe incompatible ???
-* cascading method invocation ???
-* def Class#method .. end ??
-* def Foo::Bar::baz() .. end ??
-* I18N (or M17N) script/string/regexp
-* Fixnum 0 as false ????
-* discourage use of symbol variables (e.g. $/, etc.) in manual
-* discourage use of Perlish features by giving warnings.
-* non confusing in-block local variable (is it possible?)
-  + remove scope by block
-  + variables appears within block may have independent values.
-* Regexp: make /o thread safe.
-* decide whether begin with rescue or ensure make do..while loop.
-* a +1 to be a+1, not a(+1).
-* unify == and eql? again
-* to_i returns nil if str contains no digit.
-* raise exception by `` error
-* jar like combined library package. -> RubyGems?
-* resumable Exception via Exception#resume.
-* method combination, e.g. before, after, around, etc.
-* .. or something like defadvice in Emacs.
-* property - for methods, or for objects in general.
-* "in" modifier, to annotate, or to encourage assertion.
-* selector namespace - something like generic-flet in CLOS, to help RubyBehavior
-* private instance variable (as in Python?) @_foo in class Foo => @_Foo_foo
-* warn/error "bare word" method, like "foo",  you should type "foo()"
-* clarify evaluation order of operator argument (=~, .., ...)
-* :symbol => value hash in the form of {symbol: value, ...} ??
-
-Hacking Interpreter
-
-- generational GC
-* non-blocking open (e.g. for named pipe) for thread
-* avoid blocking with gethostbyname/gethostbyaddr (use fork ???)
-* objectify interpreters ???
-* remove rb_eval() recursions
-* syntax tree -> bytecode ???
-* scrambled script, or script filter
-* setuid ruby
-* performance tune for in-block (dynamic) local variables.
-* give warnings to assign magic variables.
-* export rb_io_{addstr,printf,puts,print}
-* autoload should work with threads [ruby-talk:4589]
-* remove stdio dependency from IOs.
-* warn for inconsistent local variable usage (lv m and method m at the same time). 
-* MicroRuby
-* Built-in Interactive Ruby.
-* Parser API
-* trap every method invocation, which can be enabled by e.g. trap_call :method.
-* unify Errno exceptions of same errno, or new exception comparison scheme.
-* 2.times{|i| if i==0 then a = 15 else puts eval("a") end} should print nil.
-* Thread#max_stack_size attribute (possible??)

-Standard Libraries
-
-- Module#define_method which takes a name and a body (block, proc or method).
-- Enume#inject
-- Array#fetch
-- IO::for_fd
-- Process::waitall [ruby-talk:4557]
-- Process::Status
-- File::lchown, File::lchmod; xxx - still need work for non existing platforms
-- move Time::times to Process.
-- Enumerable#sort_by for Schwartzian transformation
-- fork_and_kill_other_threads.
-- signal list (Signal::trap, Signal::list).
-- move NameError under StandardError.
-- Integer#to_s(base)
-- Hash::new{default}
-- hash etc. should handle self referenceing array/hash
-- Array#select(n1,n2...) works like Array#indexes(n1,n2...)
-- use Mersenne Twister RNG for random.
-- deprecate Array#indexes, and Array#indices.
-- remove dependency on MAXPATHLEN.
-* String#scanf(?)
-* Object#fmt(?)
-* Time::strptime
-* Integer[num], Float[num];  Fixnum[num]?
-* method to retrieve non-number trailer for to_i/to_f.
-* Stream or Port, abstract superclass of IO ?
-* String#{pred,prev}, String#downto
-* optional stepsize argument for succ()
-* Ruby module -- Ruby::Version, Ruby::Interpreter
-* introduce Boolean class; super of TrueClass, FalseClass
-* synchronized method - synchronized{...}, synchronized :foo, :bar
-* Array#&, Array#| to allow duplication. ???
-* way to specify immortal (fork endurance) thread;
-* or raise ForkException to every thread but fork caller.
-* new user-defined marshal scheme. _dump(dumper), _load(restorer)
-* library to load per-user profile seeking .ruby_profile or ruby.ini file.
-* warning framework (warn, warning for Ruby level)
-* marshal should not depend on sprintf (works bad with locale).
-* ternary arg pow: a.pow(b,c) == a**b%c
-* new caller(), e.g. call_stack; needs better name.
-* pointer share mechanism similar to one in String for Array.
-* require "1.6" etc. by /usr/lib/ruby/1.6/1.6.rb ;-)
-* save both "feature names" and "normalized path" in $"
-* implement Mutex_m (or MutexMixin) using Mutex.
-
-Extension Libraries
-
-* ptk.rb pTk wrapper that is compatible to tk.rb
-* Berkeley DB extension
-* BitVector
-* thread-safe fcgi
-
-Ruby Libraries
-
-* urllib.rb, nttplib.rb, etc.
-* format like perl's
-
-Tools
-
-* freeze or undump to bundle everything
-* bundle using zlib

+ *  You can use this method in two use cases: a find-minimum mode and

+ *  monotone (or sorted) with respect to the block.
+ *
+ *  In find-minimum mode (this is a good choice for typical use case),

+ *
+ *  - the block returns false for any element whose index is less than
+ *    i, and
+ *  - the block returns true for any element whose index is greater

+ *     ary.bsearch {|x| x >= 100 } #=> nil
+ *
+ *  In find-any mode (this behaves like libc's bsearch(3)), the block
+ *  must return a number, and there must be two indices i and j
+ *  (0 <= i <= j <= ary.size) so that:
+ *
+ *  - the block returns a positive number for ary[k] if 0 <= k < i,
+ *  - the block returns zero for ary[k] if i <= k < j, and
+ *  - the block returns a negative number for ary[k] if
+ *    j <= k < ary.size.
+ *
+ *  Under this condition, this method returns any element whose index

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

-     * sed   ((<URL:http://gnuwin32.sourceforge.net/packages/sed.htm>))
-
-(4) We strongly recommend to build ruby on C++Builder, to link following files.
-     * usebormm.lib
-     * memmgr.lib
-
-    RTL's internal memory manager cannot handle large memory block properly,
-    so we should use borlndmm.dll instead.
-     10000.times { "" << "." * 529671; GC.start } # crash
-
-== How to compile and install
-
-(1) Execute bcc32\configure.bat on your build directory.
-     ex. c:\ruby-1.6.7>bcc32\configure.bat
-     
-(2) Change ((|RUBY_INSTALL_NAME|)) and ((|RUBY_SO_NAME|)) in (({Makefile}))
-    if you want to change the name of the executable files. 
-    And add ((|RUBYW_INSTALL_NAME|)) to change the name of the
-    executable without console window if also you want.
-
-(3) Run `((%make%))'
-
-(4) Run `((%make test%))'
-
-(5) Run `((%make DESTDIR=<install_directory> install%))'
-
-    This command will create following directories and install files onto them.
-      * <install_directory>\bin
-      * <install_directory>\lib
-      * <install_directory>\lib\ruby
-      * <install_directory>\lib\ruby\<MAJOR>.<MINOR>
-      * <install_directory>\lib\ruby\<MAJOR>.<MINOR>\<PLATFORM>
-      * <install_directory>\lib\ruby\site_ruby
-      * <install_directory>\lib\ruby\site_ruby\<MAJOR>.<MINOR>
-      * <install_directory>\lib\ruby\site_ruby\<MAJOR>.<MINOR>\<PLATFORM>
-      * <install_directory>\man\man1
-    If Ruby's version is `x.y.z', the ((|<MAJOR>|)) is `x' and the ((|<MINOR>|)) is `y'.
-    The ((|<PLATFORM>|)) is usually `(({i586-bccwin32}))'.
-
-(6) Requires dynamic RTL (cc3250.dll on C++Builder5) and borlndmm.dll (If built with
-    usebormm.lib) to use installed binary. These files are ordinary in bcc32's bin
-    directory.
-
-== Icons
-
-Any icon files(*.ico) in the build directory, directories specified with
-((|icondirs|)) make variable and (({win32})) directory under the ruby
-source directory will be included in DLL or executable files, according
-to their base names.
-    $(RUBY_INSTALL_NAME).ico or ruby.ico   --> $(RUBY_INSTALL_NAME).exe
-    $(RUBYW_INSTALL_NAME).ico or rubyw.ico --> $(RUBYW_INSTALL_NAME).exe
-    the others                             --> $(RUBY_SO_NAME).dll
-
-Although no icons are distributed with the ruby source or in the official 
-site, you can use anything you like. For example, followings are written 
-in Japanese, but you can download at least.
-
-* ((<URL:http://member.nifty.ne.jp/ueivu/rubyico.html>)) or
-  ((<zipped icons|URL:http://member.nifty.ne.jp/ueivu/Ruby_ico.zip>))
-* ((<URL:http://homepage1.nifty.com/a_nakata/ruby/>)) or
-  ((<icon itself|URL:http://homepage1.nifty.com/a_nakata/ruby/RubyIcon.ico>))
-
-== Build examples
-
-* Build on the ruby source directory.
-
-  ex.)
-    ruby source directory:  C:\ruby
-    build directory:        C:\ruby
-    install directory:      C:\usr\local
-
-    C:
-    cd \ruby
-    bcc32\configure
-    make
-    make test
-    make DESTDIR=/usr/local install
-
-* Build on the relative directory from the ruby source directory and CPU type 
-  i386.
-
-  ex.)
-    ruby source directory:  C:\ruby
-    build directory:        C:\ruby\bccwin32
-    install directory:      C:\usr\local
-    CPU                     i386
-    
-    C:
-    cd \ruby
-    mkdir bccwin32
-    cd bccwin32
-    ..\bcc32\configure target i386-bccwin32
-    make
-    make test
-    make DESTDIR=/usr/local install
-
-* Build on the different drive.
-
-  ex.)
-    ruby source directory:  C:\src\ruby
-    build directory:        D:\build\ruby
-    install directory:      C:\usr\local
-
-    D:
-    cd D:\build\ruby
-    C:\src\ruby\bcc32\configure
-    make
-    make test
-    make DESTDIR=C:/usr/local install
-
-== Bugs
-
-You can ((*NOT*)) use a path name contains any white space characters as
-the ruby source directory, this restriction comes from the behavior of
-(({!INCLUDE})) directives of (({MAKE})).
-((- you may call it a bug. -))
