+	* 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.

-	  The issue of this approach is some objects can promoted as old

-	  old objects are not freed.
+Sun Sep 24 12:11:16 2006  Tadayoshi Funaba  <tadf@dotrb.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.
+	* lib/date.rb, lib/date/format.rb: updated based on date2 3.9.3.
 
-	  To solve this problem, generational GC with more generations
-	  technique is known. This patch implements three generations gen GC.
+Sat Sep 23 23:24:57 2006  why the lucky stiff  <why@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.
+	* eval.c (rb_thread_save_context, rb_thread_restore_context):
+	  sandbox hook to save and restore sandbox state.
 
-	  Representation of generations:
-	  * Infant: !FL_PROMOTED and !oldgen_bitmap [00]

-	  * Old   :  FL_PROMOTED and  oldgen_bitmap [11]
+	* eval.c (thread_no_ensure): added THREAD_NO_ENSURE thread flag.
 
-	  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

-	  Based on patch by Juanito Fatas [Fixes GH-360]
-	  https://github.com/ruby/ruby/pull/360
+	  * WSDLDriver capitalized name operation bug fixed.  from

+	    KeywordSearchRequest in AWS) is defined as a method having
+	    uncapitalized name. (converted with GenSupport.safemethodname
+	    to handle operation name 'foo-bar').  it introduced serious

+
+	* 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>
+
+	* 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.
+
+	* 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.
+
+	* 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.
+
+	* 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.
+
+	* 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.
+
+	* main.c: also create hard reference to objc_msgSend() on NeXT
+	  platforms (in addition to Apple platforms).
+
+	* 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').
+
+	* 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()
+
+	* 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.
+
+	* 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.
+
+	* ext/pty/pty.c: include "util.h" for strdup()/ruby_strdup() for
+	  platforms such as NextStep and OpenStep which lack strdup().
+
+	* ext/socket/getaddrinfo.c: cast first argument of getservbyname(),
+	  gethostbyaddr(), and gethostbyname() from (const char*) to non-const
+	  (char*) for older platforms such as NextStep and OpenStep.
+
+	* ext/socket/socket.c: include "util.h" for strdup()/ruby_strdup() for
+	  platforms such as NextStep and OpenStep which lack strdup(); include
+	  <netinet/in_systm.h> if present for NextStep and OpenStep; cast first
+	  argument of gethostbyaddr() and getservbyname() from (const char*) to
+	  non-const (char*) for older platforms.
+
+	* ext/syslog/syslog.c: include "util.h" for strdup()/ruby_strdup() for
+	  platforms such as NextStep and OpenStep which lack strdup().

+		  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!

 This document is a list of user visible feature changes made between
-releases except for bug fixes.
+releases excluding 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.
-
-=== 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
-  * improvements:
-    * introduced the generational GC a.k.a RGenGC.
-  * added environment variables:
-    * RUBY_GC_HEAP_INIT_SLOTS
-    * RUBY_GC_HEAP_FREE_SLOTS
-    * RUBY_GC_HEAP_GROWTH_FACTOR
-    * RUBY_GC_HEAP_GROWTH_MAX_SLOTS
-    * RUBY_GC_MALLOC_LIMIT_MAX
-    * 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:
-      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
-
-* String
-  * "literal".freeze is now optimized to return the same object
-  * New methods:
-    * String#scrub and String#scrub! verify and fix invalid byte sequence.
-      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_sourceline
-    * 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 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).

+
+* fileutils
+
+  * New option for FileUtils.cp_r(): :remove_destination

+* thread
+
+  * Replaced with much faster mutex implementation in C.
+    The former implementation is available with a
+    configure option `--disable-fastthread'.
 
-    * 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.

-    to #readpartial and #read.
+  * New method: WEBrick::Cookie.parse_set_cookies()
 
-* 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.
+=== Compatibility issues (excluding feature bug fixes)
 
-=== Stdlib compatibility issues (excluding feature bug fixes)
+* builtin classes
 
-* Set
-  * incompatible changes:
-    * Set#to_set now returns self instead of generating a copy.
+  * String#intern now raises SecurityError when $SAFE level is greater
+    than zero.
 
-* 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.
+* fileutils
 
-=== C API updates
-
-* rb_gc_set_params() is deprecated. This is only used in Ruby internal.
+  * A minor implementation change breaks Rake <=0.7.1.
+    Updating Rake to 0.7.2 fixes the problem.
 
-* rb_gc_count() added. This returns the number of times GC occurred.
+* digest
 
-* rb_gc_stat() added. This allows access to specific GC.stat() values from C
-  without any allocation overhead.
+  * The constructor does no longer take an initial
+    string to feed; digest() and hexdigest() now do,
+    instead.  The following examples show how to
+    migrate:
 
-* 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.

-== Data-Types
+
+1.1 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
+	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_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

+	T_MATCH
+	T_UNDEF
+	T_VARMAP
+	T_SCOPE
+	T_NODE
 
 Most of the types are represented by C structures.

+The data for type T_NIL, T_FALSE, T_TRUE are nil, true, false
 respectively.  They are singletons for the data type.
-The equivalent C constants are: Qnil, Qfalse, Qtrue.
-Note that Qfalse is false in C also (i.e. 0), but not Qnil.
-
-The T_FIXNUM data is a 31bit or 63bit length fixed integer.
-This size 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,

-can be used to retrieve the double float value in the same way.

+The T_FIXNUM data is a 31bit length fixed integer (63bit length on
+some machines), which can be converted to a C integer by using the
+FIX2INT() macro.  There is also NUM2INT() which converts any Ruby
+numbers into C integers.  The NUM2INT() macro 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.
+
+In version 1.7 or later it is recommended that you use the new 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 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.
+In version 1.6 or earlier, STR2CSTR() was used to do the same thing
+but now it is deprecated in version 1.7, because STR2CSTR() has a risk
+of a dangling pointer problem in the to_str() impliclit conversion.
 
 Other data types have corresponding C structures, e.g. struct RArray
-for T_ARRAY etc. The VALUE of the type which has the corresponding
-structure can be cast to retrieve the pointer to the struct.  The
-casting macro will be of the form RXXXX for each data type; for
-instance, RARRAY(obj).  See "ruby.h".  However, we do not recommend
-to access RXXXX data directly because these data 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).
-
-There are some accessing macros for structure members, for example
-`RSTRING_LEN(str)' to get the size of the Ruby String object.  The

-
-Some macros to check API compatibilities are available by default.
-

-
-  Means that NORETURN macro is functional style instead of prefix.
-
-HAVE_RB_DEFINE_ALLOC_FUNC ::
-
-  Means that function rb_define_alloc_func() is provided, that means the
-  allocation framework is used.  This is same as the result of
-  have_func("rb_define_alloc_func", "ruby.h").
-
-HAVE_RB_REG_NEW_STR ::
-
-  Means that function rb_reg_new_str() is provided, that creates Regexp
-  object from String object.  This is same as the result of
-  have_func("rb_reg_new_str", "ruby.h").
-
-HAVE_RB_IO_T ::
-
-  Means that type rb_io_t is provided.
-
-USE_SYMBOL_AS_METHOD_NAME ::
-
-  Means that Symbols will be returned as method names, e.g.,
-  Module#methods, #singleton_methods and so on.
-
-HAVE_RUBY_*_H ::
-
-  Defined in ruby.h and means corresponding header is available.  For
-  instance, when HAVE_RUBY_ST_H is defined you should use ruby/st.h not
-  mere st.h.
-
-RB_EVENT_HOOKS_HAVE_CALLBACK_DATA ::
+Appendix C. Functions Available in extconf.rb
 
-  Means that rb_add_event_hook() takes the third argument `data', to be
-  passed to the given event hook function.
+These functions are available in extconf.rb:
 
-= Appendix C. Functions available for use in extconf.rb
+ have_macro(macro, headers)
 
-See documentation for {mkmf}[rdoc-ref:MakeMakefile].
+Checks whether macro is defined with header.  Returns true if the macro
+is defined.
 
-= Appendix D. Generational GC
+ have_library(lib, func)
 
-Ruby 2.1 introduced a generational garbage collector (called RGenGC).
-RGenGC (mostly) keeps compatibility.
+Checks whether the library exists, containing the specified function.
+Returns true if the library exists.
 
-Generally, the use of the technique called write barriers is required in
-extension libraries for generational GC
-(http://en.wikipedia.org/wiki/Garbage_collection_%28computer_science%29).
-RGenGC works fine without write barriers in extension libraries.
+ find_library(lib, func, path...)
 
-If your library adheres to the following tips, performance can
-be further improved. Especially, the "Don't touch pointers directly" section is
-important.
+Checks whether a library which contains the specified function exists in
+path.  Returns true if the library exists.
 
-== Incompatibility
+ have_func(func, header)
 
-You can't write RBASIC(obj)->klass field directly because it is const
-value now.
+Checks whether func exists with header.  Returns true if the function
+exists.  To check functions in an additional library, you need to
+check that library first using have_library().
 
-Basically you should not write this field because MRI expects it to be
-an immutable field, but if you want to do it in your extension you can
-use the following functions:
+ have_var(var, header)
 
-VALUE rb_obj_hide(VALUE obj) ::
+Checks whether var exists with header.  Returns true if the variable
+exists.  To check variables in an additional library, you need to
+check that library first using have_library().
 
-  Clear RBasic::klass field. The object will be an internal object.
-  ObjectSpace::each_object can't find this object.
+ have_header(header)
 
-VALUE rb_obj_reveal(VALUE obj, VALUE klass) ::
+Checks whether header exists.  Returns true if the header file exists.
 
-  Reset RBasic::klass to be klass.
-  We expect the `klass' is hidden class by rb_obj_hide().
+ find_header(header, path...)
 
-== Write barriers
+Checks whether header exists in path.  Returns true if the header file
+exists.
 
-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.
+ have_struct_member(type, member, header)
 
-=== Don't touch pointers directly
+Checks whether type has member with header.  Returns true if the type
+is defined and has the member.
 
-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.
+ have_type(type, header, opt)
 
-DO NOT USE THESE MACROS and instead use the corresponding C-APIs such as
-rb_ary_aref(), rb_ary_store() and so on.
+Checks whether type is defined with header.  Returns true if the type
+is defined.
 
-=== Consider whether to insert write barriers
+ check_sizeof(type, header)
 
-You don't need to care about write barriers if you only use built-in
-types.
+Checks the size of type in char with header.  Returns the size if the
+type is defined, otherwise nil.
 
-If you support T_DATA objects, you may consider using write barriers.
+ create_makefile(target)
 
-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.
+Generates the Makefile for the extension library.  If you don't invoke
+this method, the compilation will not be done.
 
-(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.
+ find_executable(bin, path)
 
-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.
+Finds command in path, which is File::PATH_SEPARATOR-separated list of
+directories.  If path is nil or omitted, environment varialbe PATH
+will be used.  Returns the path name of the command if it is found,
+otherwise nil.
 
-=== Combine with built-in types
+ with_config(withval[, default=nil])
 
-Please consider utilizing built-in types. Most built-in types support
-write barrier, so you can use them to avoid manually inserting write
-barriers.
+Parses the command line options and returns the value specified by
+--with-<withval>.
 
-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.
+ enable_config(config, *defaults)
+ disable_config(config, *defaults)
 
-With use of such techniques, you don't need to insert write barriers
-anymore.
+Parses the command line options for boolean.  Returns true if
+--enable-<config> is given, or false if --disable-<config> is given.
+Otherwise, yields defaults to the given block and returns the result
+if it is called with a block, or returns defaults.
 
-=== Insert write barriers
+ dir_config(target[, default_dir])
+ dir_config(target[, default_include, default_lib])
 
-[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.
+Parses the command line options and adds the directories specified by
+--with-<target>-dir, --with-<target>-include, and/or --with-<target>-lib
+to $CFLAGS and/or $LDFLAGS.  --with-<target>-dir=/path is equivalent to
+--with-<target>-include=/path/include --with-<target>-lib=/path/lib.
+Returns an array of the added directories ([include_dir, lib_dir]).
 
-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.
+ pkg_config(pkg)
 
-For a complete guide for RGenGC and write barriers, please refer to
-<https://bugs.ruby-lang.org/projects/ruby-trunk/wiki/RGenGC>.
+Obtains the information for pkg by pkg-config command.  The actual
+command name can be overriden by --with-pkg-config command line
+option.

-= 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．
+���饹��⥸�塼���������뤿��ˤϡ��ʲ��δؿ���Ȥ��ޤ���
 
   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．
+�����δؿ��Ͽ�����������줿���饹��⥸�塼����֤��ޤ���
+�᥽�åɤ����������ˤ������ͤ�ɬ�פʤΤǡ��ۤȤ�ɤξ��
+������ͤ��ѿ��˳�Ǽ���Ƥ���ɬ�פ�����Ǥ��礦��
 
-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．
+���饹��⥸�塼���¾�Υ��饹�������˥ͥ��Ȥ�������������
+�ϰʲ��δؿ���Ȥ��ޤ���
 
   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．
+2.1.2 �᥽�å�/�ðۥ᥽�å����
 
-  void rb_define_method(VALUE klass, const char *name,
-                        VALUE (*func)(), int argc)
+�᥽�åɤ��ðۥ᥽�åɤ��������ˤϰʲ��δؿ���Ȥ��ޤ���
 
-  void rb_define_singleton_method(VALUE object, const char *name,
-                                  VALUE (*func)(), int argc)
+  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．

-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
+�⤦�ҤȤĤϥ⥸�塼��ؿ�����������ΤǤ����⥸�塼��ؿ�

+�ʲ����̤�Ǥ���
 
   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

-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
+(1) �ǥ��쥯�ȥ����
 
   % 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．

+Language Spec.
+
+- 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.

- *
- *  You can use this method in two use cases: a find-minimum mode and
- *  a find-any mode.  In either case, the elements of the array must be
- *  monotone (or sorted) with respect to the block.
- *
- *  In find-minimum mode (this is a good choice for typical use case),
- *  the block must return true or false, and there must be an index i
- *  (0 <= i <= ary.size) so that:
- *
- *  - the block returns false for any element whose index is less than
- *    i, and
- *  - the block returns true for any element whose index is greater
- *    than or equal to i.

- *  This method returns the i-th element.  If i is equal to ary.size,

- *     ary.bsearch {|x| x >=  -1 } #=> 0
- *     ary.bsearch {|x| x >= 100 } #=> nil
- *
- *  In find-any mode (this behaves like libc's bsearch(3)), the block
- *  must return a number, and there must be two indices i and j
- *  (0 <= i <= j <= ary.size) so that:
- *
- *  - the block returns a positive number for ary[k] if 0 <= k < i,
- *  - the block returns zero for ary[k] if i <= k < j, and
- *  - the block returns a negative number for ary[k] if
- *    j <= k < ary.size.
- *
- *  Under this condition, this method returns any element whose index
- *  is within i...j.  If i is equal to j (i.e., there is no element
- *  that satisfies the block), this method returns nil.
- *
- *     ary = [0, 4, 7, 10, 12]

- *     # try to find v such that 8 <= v < 10
- *     ary.bsearch {|x| 4 - x / 2 } #=> nil
- *
- *  You must not mix the two modes at a time; the block must always

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

+= How to build ruby using Borland C++
+
+== Requirement
+
+(1) Borland C++ 5.0 or later.
+
+(2) Please set environment variable (({PATH}))
+    to run required commands properly from the command line.
+
+    Note: building ruby requires following commands.
+     * make
+     * bcc32
+     * tlib
+     * ilink32
+
+(3) If you want to build from CVS source, following commands are required.
+     * byacc ((<URL:http://gnuwin32.sourceforge.net/packages/byacc.htm>))
+     * 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. -))
+

-# WHY?
-#   Since any found solution has an inverse we want to maximize finding solutions that are not already found
-#   as an inverse.  The inverse will ALWAYS be 3 one of the piece configurations that is exactly 3 rotations away
-#   (an odd number).  Checking even vs odd then produces a higher probability of finding more pieces earlier
-#   in the cycle.  We still need to keep checking all the permutations, but our probability of finding one will
-#   diminsh over time.  Since we are TOLD how many to search for this lets us exit before checking all pieces

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

- *
- * This function returns the signedness and overflow condition.
- * The overflow condition depends on INTEGER_PACK_2COMP.

- *   2 : positive overflow.  2**(numwords*(wordsize*CHAR_BIT-nails)) <= val
- *
- * INTEGER_PACK_2COMP is specified:
- *   -2 : negative overflow.  val < -2**(numwords*(wordsize*CHAR_BIT-nails))
- *   -1 : negative without overflow.  -2**(numwords*(wordsize*CHAR_BIT-nails)) <= val < 0

- *
- * The value, -2**(numwords*(wordsize*CHAR_BIT-nails)), is representable
