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

-
-	* ext/tk/*: full update Ruby/Tk to support Ruby(1.9|1.8) and Tc/Tk8.5.
-
-	* ext/tk/lib/tkextlib/tile.rb: [incompatible] remove TileWidgets' 
-	  instate/state/identify method to avoid the conflict with standard
-	  widget options. Those methods are renamed to ttk_instate/ttk_state/
-	  ttk_identify (tile_instate/tile_state/tile_identify are available 
-	  too). Although I don't recommend, if you realy need old methods, 
-	  please define "Tk::USE_OBSOLETE_TILE_STATE_METHOD = true" before 
-	  "require 'tkextlib/tile'".
-
-	* ext/tk/lib/tkextlib/tile.rb: "Tk::Tile::__Import_Tile_Widgets__!"
-	  is obsolete. It outputs warning. To control default widget set, 
-	  use "Tk.default_widget_set = :Ttk".
-
-	* ext/tk/lib/tk.rb: __IGNORE_UNKNOWN_CONFIGURE_OPTION__ method and 
-	  __set_IGNORE_UNKNOWN_CONFIGURE_OPTION__!(mode) method are defind 
-	  as module methods of TkConfigMethod. It may help users to wrap old 
-	  Ruby/Tk scripts (use standard widgets) to force to use Ttk widgets.
-	  Ttk widgets don't have some options of standard widgets which are 
-	  control the view of widgets. When set ignore-mode true, configure 
-	  method tries to ignoure such unknown options with no exception. 
-	  Of course, it may raise other troubles on the GUI design. 
-	  So, those are a little danger methods. 
-
-	* ext/tk/lib/tk/itemconfig.rb: __IGNORE_UNKNOWN_CONFIGURE_OPTION__ 
-	  method and __set_IGNORE_UNKNOWN_CONFIGURE_OPTION__!(mode) method 
-	  are defind as module methods of TkItemConfigMethod as the same 
-	  purpose as TkConfigMethod's ones.
-
-	* ext/tk/sample/ttk_wrapper.rb: A new example. This is a tool for 
-	  wrapping old Ruby/Tk scripts (which use standard widgets) to use 
-	  Ttk (Tile) widgets as default.
-
-	* ext/tk/sample/tkextlib/tile/demo.rb: use ttk_instate/ttk_state 
-	  method instead of instate/state method.
-
-	* ext/tk/lib/tk/root, ext/tk/lib/tk/namespace.rb,
-	  ext/tk/lib/tk/text.rb, ext/tk/lib/tkextlib/*: some 'instance_eval's  
-	  are replaced to "instance_exec(self)".
-
-	* ext/tk/lib/tk/event.rb: bug fix on KEY_TBL and PROC_TBL (?x is not 
-	  a character code on Ruby1.9).
-
-	* ext/tk/lib/tk/variable.rb: support new style of operation argument 
-	  on Tcl/Tk's 'trace' command for variables. 
-
-	* ext/tk/sample/demos-jp/widget, ext/tk/sample/demos-en/widget: bug fix
-
-	* ext/tk/sammple/demos-jp/textpeer.rb,

-
-	* ext/tk/lib/tk.rb: remove Thread.critical access if Ruby1.9
-
-	* ext/tk/lib/tk/multi-tk.rb: support Ruby1.9 (probably)
-
-	* ext/tk/lib/tkextlib/tile.rb: add method to define Tcl/Tk command 
-	  to make Tcl/Tk theme sources (based on different version of Tile 
-	  extension) available. 
-	  (Tk::Tile::__define_LoadImages_proc_for_comaptibility__)
-
-	* ext/tk/lib/tk.rb, ext/tk/lib/tk/wm.rb: support dockable frames
-	  (Tcl/Tk8.5 feature). 'wm' command can treat many kinds of widgets 
-	  as toplevel widgets.
-
-	* ext/tk/lib/tkextlib/tile/style.rb: ditto.
-	  (Tk::Tile::Style.__define_wrapper_proc_for_compatibility__)
-
-	* ext/tk/lib/tk/font.rb: add actual_hash and metrics_hash to get 
-	  properties as a hash. metrics_hash method returns a boolean value 
-	  for 'fixed' option. But metrics method returns numeric value 
-	  (0 or 1) for 'fixed' option, because of backward compatibility. 
-
-	* ext/tk/lib/tk/timer.rb: somtimes fail to set callback procedure.
-
-	* ext/tk/lib/tk.rb: add Tk.sleep and Tk.wakeup method. Tk.sleep 
-	  doesn't block the eventloop. It will be better to use the method 
-	  in event callbacks.
-
-	* ext/tk/sample/tksleep_sample.rb: sample script about Tk.sleep.

-
-	* ext/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.

-
-	* lib/{soap,wsdl,xsd}, test/{soap,wsdl,xsd}: imported soap4r/1.5.4.
-
-	  == SOAP client and server ==
-
-	  === for both client side and server side ===
-
-	  * improved document/literal service support.
-	    style(rpc,document)/use(encoding, literal) combination are all
-	    supported.  for the detail about combination, see
-	    test/soap/test_style.rb.
-
-	  * let WSDLEncodedRegistry#soap2obj map SOAP/OM to Ruby according to
-	    WSDL as well as obj2soap.  closes #70.
-
-	  * let SOAP::Mapping::Object handle XML attribute for doc/lit service.
-	    you can set/get XML attribute via accessor methods which as a name
-	    'xmlattr_' prefixed (<foo name="bar"/> -> Foo#xmlattr_name).
-
-	  === client side ===
-
-	  * WSDLDriver capitalized name operation bug fixed.  from
-	    1.5.3-ruby1.8.2, operation which has capitalized name (such as
-	    KeywordSearchRequest in AWS) is defined as a method having
-	    uncapitalized name. (converted with GenSupport.safemethodname
-	    to handle operation name 'foo-bar').  it introduced serious
-	    incompatibility; in the past, it was defined as a capitalized.
-	    define capitalized method as well under that circumstance.
-
-	  * added new factory interface 'WSDLDriverFactory#create_rpc_driver'
-	    to create RPC::Driver, not WSDLDriver (RPC::Driver and WSDLDriver
-	    are merged).  'WSDLDriverFactory#create_driver' still creates
-	    WSDLDriver for compatibility but it warns that the method is
-	    deprecated.  please use create_rpc_driver instead of create_driver.
-
-	  * allow to use an URI object as an endpoint_url even with net/http,
-	    not http-access2.
-
-	  === server side ===
-
-	  * added mod_ruby support to SOAP::CGIStub.  rename a CGI script
-	    server.cgi to server.rb and let mod_ruby's RubyHandler handles the
-	    script.  CGIStub detects if it's running under mod_ruby environment
-	    or not.
-
-	  * added fcgi support to SOAP::CGIStub.  see the sample at
-	    sample/soap/calc/server.fcgi.  (almost same as server.cgi but has
-	    fcgi handler at the bottom.)
-
-	  * allow to return a SOAPFault object to respond customized SOAP fault.
-
-	  * added the interface 'generate_explicit_type' for server side
-	    (CGIStub, HTTPServer).  call 'self.generate_explicit_type = true'
-	    if you want to return simplified XML even if it's rpc/encoded
-	    service.
-
-	  == WSDL ==
-
-	  === WSDL definition ===
-
-	  * improved XML Schema support such as extension, restriction,
-	    simpleType, complexType + simpleContent, ref, length, import,
-	    include.
-
-	  * reduced "unknown element/attribute" warnings (warn only 1 time for
-	    each QName).
-
-	  * importing XSD file at schemaLocation with xsd:import.
-
-	  === code generation from WSDL ===
-
-	  * generator crashed when there's '-' in defined element/attribute
-	    name.
-
-	  * added ApacheMap WSDL definition.
-
-	* sample/{soap,wsdl}: removed.

-
-	* 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.

-	* test/csv/test_csv.rb: updated.

-	* test/ruby/test_float.rb: added test_strtod to test Float("0").

-	  _thread_tkwait.
-
-	* ext/tk/lib/tk.rb: now, TkVariable#wait has 2 arguments.

-	  Find it.  :-)
-

-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!

+(e.g. <tt>https://bugs.ruby-lang.org/issues/$FEATURE_OR_BUG_NUMBER</tt>)
 
-* REXML
+== Changes since the 2.5.0 release
 
-  * REXML::Document.entity_expansion_limit=
+=== Language changes
 
-    New method to set the entity expansion limit. By default the limit is
-    set to 10000.  See the following URL for details.
+* <code>$SAFE</code> is a process global state and we can set 0 again. [Feature #14250]
 
-    http://www.ruby-lang.org/en/news/2008/08/23/dos-vulnerability-in-rexml/
+* refinements take place at block passing.  [Feature #14223]
 
-== Changes since the 1.8.6 release
+* refinements take place at Kernel#public_send.  [Feature #15326]
 
-=== Configuration changes
+* refinements take place at Kernel#respond_to?.  [Feature #15327]
 
-* vendor_ruby directory
+* +else+ without +rescue+ now causes a syntax error.  [EXPERIMENTAL] [Feature #14606]
 
-  A new library directory named `vendor_ruby' is introduced in
-  addition to `site_ruby'.  The idea is to separate libraries
-  installed by the package system (`vendor') from manually (`site')
-  installed libraries preventing the former from getting overwritten
-  by the latter, while preserving the user option to override vendor
-  libraries with site libraries. (`site_ruby' takes precedence over
-  `vendor_ruby')
+* constant names may start with a non-ASCII capital letter. [Feature #13770]
 
-  If you are a package maintainer, make each library package configure
-  the library passing the `--vendor' option to `extconf.rb' so that
-  the library files will get installed under `vendor_ruby'.
+* An endless range is introduced.  You can write a range that has no end,
+  like <code>(0..)</code> (or similarly <code>(0...)</code>).
+  The following shows typical use cases.  [Feature #12912]
 
-  You can change the directory locations using configure options such
-  as `--with-sitedir=DIR' and `--with-vendordir=DIR'.
+    ary[1..]                              # identical to ary[1..-1]
+    (1...).each {|index| block }          # infinite loop from index 1
+    ary.zip(1..) {|elem, index| block }   # ary.each.with_index(1) { }
 
-=== Global constants
+* Non-Symbol key in keyword arguments hash causes an exception.
 
-* new constants
+* "shadowing outer local variable" warning was removed.  [Feature #12490]
+  You can now write the following without warning.
 
-  * RUBY_COPYRIGHT
-  * RUBY_DESCRIPTION
+    user = users.find {|user| cond(user) }
 
-=== Library updates (outstanding ones only)
+* Print exception backtrace and error message in reverse order when the
+  exception is not caught and STDOUT is unchanged and a tty. [Feature #8661]
 
-* new library
+* Print +cause+ of the exception if the exception is not caught and printed
+  its backtraces and error message [Feature #8257]
 
-  * securerandom
+* Flip-flop syntax is deprecated. [Feature #5400]
 
-* builtin classes
+=== Core classes updates (outstanding ones only)
 
-  * Array#flatten
-  * Array#flatten!
+[Array]
 
-    Takes an optional argument that determines the level of recursion
-    to flatten.
+  [New methods]
 
-  * Array#eql?
-  * Array#hash
-  * Array#==
-  * Array#<=>
+    * Added Array#union and Array#difference instance methods.  [Feature #14097]

-  * Array#pop
-  * Array#shift
+    * added Binding#source_location.  [Feature #14230]
 
-    Take an optional argument specifying the number of elements to
-    remove.
+      This method returns the source location of the binding, a 2-element
+      array of <code>__FILE__</code> and <code>__LINE__</code>.
+      Traditionally, the same information could be retrieved by
+      <code>eval("[__FILE__, __LINE__]", binding)</code>, but we are
+      planning to change this behavior so that Kernel#eval ignores
+      binding's source location [Bug #4352].  So, users should use this
+      newly-introduced method instead of Kernel#eval.

+    single enumerator, generated by such methods as Enumerable#chain and
+    Enumerator#+.
 
-    Note that #map and #collect still return an array unlike Ruby 1.9
-    to keep compatibility.

+
+=== C API updates
+
+=== Implementation improvements
+
+* Speedup Proc#call because we don't need to care about <code>$SAFE</code>
+  any more. [Feature #14318]
+
+  With +lc_fizzbuzz+ benchmark which uses so many Proc#call we can
+  measure x1.4 improvements.  [Bug #10212]
+
+* Speedup block.call where +block+ is passed block parameter. [Feature #14330]
+
+  Ruby 2.5 improves block passing performance. [Feature #14045]
+
+  Additionally, Ruby 2.6 improves the performance of passed block calling.
+
+* Introduce an initial implementation of JIT (Just-in-time) compiler. [Feature #14235] [experimental]
+
+  * <tt>--jit</tt> command line option is added to enable JIT. <tt>--jit-verbose=1</tt>
+    is good for inspection.  See <tt>ruby --help</tt> for others.
+  * To generate machine code, this JIT compiler uses C compiler used for building
+    the interpreter. Currently GCC, Clang, and Microsoft Visual C++ are supported for it.
+  * <tt>--disable-mjit-support</tt> option is added to configure. This is added for JIT debugging,
+    but if you get an error on building a header file for JIT, you can use this option to skip
+    building it as a workaround.
+  * rb_waitpid reimplemented on Unix-like platforms to maintain
+    compatibility with processes created for JIT [Bug #14867]
 
-  * String#intern now raises SecurityError when $SAFE level is greater
-    than zero.
+* VM generator script renewal; makes the generated VM more optimized. [GH-1779]
 
-* date
+* Thread cache enabled for pthreads platforms (for Thread.new and
+  Thread.start).  [Feature #14757]
 
-  * Time#to_date and Time#to_datetime are added as private methods.
-    They cause name conflict error in ActiveSupport 1.4.1 and prior,
-    which comes with Rails 1.2.2 and prior.  Updating ActiveSupport
-    and/or Rails to the latest versions fixes the problem.
+* timer thread is eliminated for platforms with POSIX timers [Misc #14937]
 
-* digest
+* Transient Heap (theap) is supported. [Bug #14858] [Feature #14989]
+  theap is managed heap for short-living memory objects. For example,
+  making small and short-living Hash object is x2 faster. With rdoc benchmark,
+  we measured 6-7% performance improvement.
 
-  * The constructor does no longer take an initial string to feed.
-    The following examples show how to migrate:
+* Native implementations (arm32, arm64, ppc64le, win32, win64, x86, amd64) of
+  coroutines to improve performance of Fiber significantly. [Feature #14739]
 
-      # 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")
+=== Miscellaneous changes
 
-* fileutils
+* On macOS, shared libraries no longer include a full version number of Ruby
+  in their names.  This eliminates the burden of each teeny upgrade on the
+  platform that users need to rebuild every extension library.
 
-  * A minor implementation change breaks Rake <=0.7.1.
-    Updating Rake to 0.7.2 or higher fixes the problem.
+  [Before]
+    * libruby.2.6.0.dylib
+    * libruby.2.6.dylib -> libruby.2.6.0.dylib
+    * libruby.dylib -> libruby.2.6.0.dylib
 
-* tk
+  [After]
+    * libruby.2.6.dylib
+    * libruby.dylib -> libruby.2.6.dylib
 
-  * 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.

-
-* How to compile and install
-
-This is what you need to do to compile and install Ruby:
-
-  1. If ./configure does not exist or is older than configure.in,
-     run autoconf to (re)generate configure.
-
-  2. Run ./configure, which will generate config.h and Makefile.
-
-     Some C compiler flags may be added by default depending on your
-     environment.  Specify optflags=.. and warnflags=.. as necessary
-     to override them.
-
-  3. Edit defines.h if you need.  Usually this step will not be needed.
-
-  4. Remove comment mark(#) before the module names from ext/Setup (or
-     add module names if not present), if you want to link modules
-     statically.
-
-     If you don't want to compile non static extension modules
-     (probably on architectures which does not allow dynamic loading),
-     remove comment mark from the line "#option nodynamic" in
-     ext/Setup.
-
-  5. Run make.
-
-  6. Optionally, run 'make test' to check whether the compiled Ruby
-     interpreter works well.  If you see the message "test succeeded",
-     your ruby works as it should (hopefully).
-
-  7. Run 'make install'
-
-     You may have to be a super user to install ruby.
-
-If you fail to compile ruby, please send the detailed error report with
-the error log and machine/OS type, to help others.

-
-This document explains how to make extension libraries for Ruby.
-
-1. Basic knowledge
-
-In C, variables have types and data do not have types.  In contrast,
-Ruby variables do not have a static type, and data themselves have
-types, so data will need to be converted between the languages.
-
-Data in Ruby are represented by the C type `VALUE'.  Each VALUE data
-has its data-type.
-
-To retrieve C data from a VALUE, you need to:
-
- (1) Identify the VALUE's data type
- (2) Convert the VALUE into C data
-
-Converting to the wrong data type may cause serious problems.
-
-
-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_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
-	T_MATCH
-	T_UNDEF
-	T_VARMAP
-	T_SCOPE
-	T_NODE
-
-Most of the types are represented by C structures.
-
-1.2 Check Data Type of the VALUE
-
-The macro TYPE() defined in ruby.h shows the data type of the VALUE.
-TYPE() returns the constant number T_XXXX described above.  To handle
-data types, your code will look something like this:
-
-  switch (TYPE(obj)) {
-    case T_FIXNUM:
-      /* process Fixnum */
-      break;
-    case T_STRING:
-      /* process String */
-      break;
-    case T_ARRAY:
-      /* process Array */
-      break;
-    default:
-      /* raise exception */
-      rb_raise(rb_eTypeError, "not valid value");
-      break;
-  }
-
-There is the data-type check function
-
-  void Check_Type(VALUE value, int type)
-
-which raises an exception if the VALUE does not have the type specified.
-
-There are also faster check macros for fixnums and nil.
-
-  FIXNUM_P(obj)
-  NIL_P(obj)
-
-1.3 Convert VALUE into C data
-
-The data for type T_NIL, T_FALSE, T_TRUE are nil, true, false
-respectively.  They are singletons for the data type.
-
-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
-argument, to change the value of var in place.
-
-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".
-
-For example, `RSTRING(str)->len' is the way to get the size of the
-Ruby String object.  The allocated region can be accessed by
-`RSTRING(str)->ptr'.  For arrays, use `RARRAY(ary)->len' and
-`RARRAY(ary)->ptr' respectively.
-
-Notice: Do not change the value of the structure directly, unless you
-are responsible for the result.  This ends up being the cause of interesting
-bugs.
-
-1.4 Convert C data into VALUE
-
-To convert C data to Ruby values:
-
-  * FIXNUM
-
-    left shift 1 bit, and turn on LSB.
-
-  * Other pointer values
-
-    cast to VALUE.
-
-You can determine whether a VALUE is pointer or not by checking its LSB.  
-
-Notice Ruby does not allow arbitrary pointer values to be a VALUE.  They
-should be pointers to the structures which Ruby knows about.  The known
-structures are defined in <ruby.h>.
-
-To convert C numbers to Ruby values, use these macros.
-
-  INT2FIX()	for integers within 31bits.
-  INT2NUM()	for arbitrary sized integer.
-
-INT2NUM() converts an integer into a Bignum if it is out of the FIXNUM
-range, but is a bit slower.
-
-1.5 Manipulating Ruby data
-
-As I already mentioned, it is not recommended to modify an object's internal
-structure.  To manipulate objects, use the functions supplied by the Ruby
-interpreter. Some (not all) of the useful functions are listed below:
-
- String functions
-
-  rb_str_new(const char *ptr, long len)
-
-    Creates a new Ruby string.
-
-  rb_str_new2(const char *ptr)
-
-    Creates a new Ruby string from a C string.  This is equivalent to
-    rb_str_new(ptr, strlen(ptr)).
-
-  rb_tainted_str_new(const char *ptr, long len)
-
-    Creates a new tainted Ruby string.  Strings from external data
-    sources should be tainted.
-
-  rb_tainted_str_new2(const char *ptr)
-
-    Creates a new tainted Ruby string from a C string.
-
-  rb_str_cat(VALUE str, const char *ptr, long len)
-
-    Appends len bytes of data from ptr to the Ruby string.
-
- Array functions
-
-  rb_ary_new()
-
-    Creates an array with no elements.
-
-  rb_ary_new2(long len)
-
-    Creates an array with no elements, allocating internal buffer
-    for len elements.
-
-  rb_ary_new3(long n, ...)
-
-    Creates an n-element array from the arguments.
-
-  rb_ary_new4(long n, VALUE *elts)
-
-    Creates an n-element array from a C array.
-
-  rb_ary_push(VALUE ary, VALUE val)
-  rb_ary_pop(VALUE ary)
-  rb_ary_shift(VALUE ary)
-  rb_ary_unshift(VALUE ary, VALUE val)
-
-    Array operations.  The first argument to each functions must be an 
-    array.  They may dump core if other types are given.
-
-2. Extending Ruby with C
-
-2.1 Addding new features to Ruby
-
-You can add new features (classes, methods, etc.) to the Ruby
-interpreter.  Ruby provides APIs for defining the following things:
-
- * Classes, Modules
- * Methods, Singleton Methods
- * Constants
-
-2.1.1 Class/module definition
-
-To define a class or module, use the functions below:
-
-  VALUE rb_define_class(const char *name, VALUE super)
-  VALUE rb_define_module(const char *name)
-
-These functions return the newly created class or module.  You may
-want to save this reference into a variable to use later.
-
-To define nested classes or modules, use the functions below:
-
-  VALUE rb_define_class_under(VALUE outer, const char *name, VALUE super)
-  VALUE rb_define_module_under(VALUE outer, const char *name)
-
-2.1.2 Method/singleton method definition
-
-To define methods or singleton methods, use these functions:
-
-  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)
-
-The `argc' represents the number of the arguments to the C function,
-which must be less than 17.  But I doubt you'll need that many.
-
-If `argc' is negative, it specifies the calling sequence, not number of
-the arguments.  
-
-If argc is -1, the function will be called as:
-
-  VALUE func(int argc, VALUE *argv, VALUE obj)
-
-where argc is the actual number of arguments, argv is the C array of
-the arguments, and obj is the receiver.
-
-If argc is -2, the arguments are passed in a Ruby array. The function
-will be called like:
-
-  VALUE func(VALUE obj, VALUE args)
-
-where obj is the receiver, and args is the Ruby array containing
-actual arguments.
-
-There are two more functions to define methods.  One is to define
-private methods:
-
-  void rb_define_private_method(VALUE klass, const char *name, 
-			        VALUE (*func)(), int argc)
-
-The other is to define module functions, which are private AND singleton
-methods of the module.  For example, sqrt is the module function
-defined in Math module.  It can be called in the following way:
-
-  Math.sqrt(4)
-
-or
-
-  include Math
-  sqrt(4)
-
-To define module functions, use:
-
-  void rb_define_module_function(VALUE module, const char *name, 
-				 VALUE (*func)(), int argc)
-
-Oh, in addition, function-like methods, which are private methods defined
-in the Kernel module, can be defined using:
-
-  void rb_define_global_function(const char *name, VALUE (*func)(), int argc)
-
-To define an alias for the method,
-
-  void rb_define_alias(VALUE module, const char* new, const char* old);
-
-To define and undefine the `allocate' class method,
-
-  void rb_define_alloc_func(VALUE klass, VALUE (*func)(VALUE klass));
-  void rb_undef_alloc_func(VALUE klass);
-
-func have to take the klass as the argument and return a newly
-allocated instance.  This instance should be empty as possible,
-without any expensive (including external) resources.
-
-2.1.3 Constant definition
-
-We have 2 functions to define constants:
-
-  void rb_define_const(VALUE klass, const char *name, VALUE val)
-  void rb_define_global_const(const char *name, VALUE val)
-
-The former is to define a constant under specified class/module.  The
-latter is to define a global constant.
-
-2.2 Use Ruby features from C
-
-There are several ways to invoke Ruby's features from C code.
-
-2.2.1 Evaluate Ruby Programs in a String
-
-The easiest way to use Ruby's functionality from a C program is to
-evaluate the string as Ruby program.  This function will do the job:
-
-  VALUE rb_eval_string(const char *str)
-
-Evaluation is done under the current context, thus current local variables
-of the innermost method (which is defined by Ruby) can be accessed.
-
-2.2.2 ID or Symbol
-
-You can invoke methods directly, without parsing the string.  First I need
-to explain about ID.  ID is the integer number to represent Ruby's
-identifiers such as variable names.  The Ruby data type corresponding to ID
-is Symbol.  It can be accessed from Ruby in the form:
-
- :Identifier
-
-You can get the ID value from a string within C code by using
-
-  rb_intern(const char *name)
-
-You can retrieve ID from Ruby object (Symbol or String) given as an
-argument by using
-
-  rb_to_id(VALUE symbol)
-
-You can convert C ID to Ruby Symbol by using
-
-  VALUE ID2SYM(ID id)
-
-and to convert Ruby Symbol object to ID, use
-
-  ID SYM2ID(VALUE symbol)
-
-2.2.3 Invoke Ruby method from C
-
-To invoke methods directly, you can use the function below
-
-  VALUE rb_funcall(VALUE recv, ID mid, int argc, ...)
-
-This function invokes a method on the recv, with the method name
-specified by the symbol mid.
-
-2.2.4 Accessing the variables and constants
-
-You can access class variables and instance variables using access
-functions.  Also, global variables can be shared between both environments.
-There's no way to access Ruby's local variables.
-
-The functions to access/modify instance variables are below:
-
-  VALUE rb_ivar_get(VALUE obj, ID id)
-  VALUE rb_ivar_set(VALUE obj, ID id, VALUE val)
-
-id must be the symbol, which can be retrieved by rb_intern().
-
-To access the constants of the class/module:
-
-  VALUE rb_const_get(VALUE obj, ID id)
-
-See 2.1.3 for defining new constant.
-
-3. Information sharing between Ruby and C
-
-3.1 Ruby constants that C can be accessed from C
-
-The following Ruby constants can be referred from C.
-
-  Qtrue
-  Qfalse
-
-Boolean values.  Qfalse is false in C also (i.e. 0).
-
-  Qnil
-
-Ruby nil in C scope.
-
-3.2 Global variables shared between C and Ruby
-
-Information can be shared between the two environments using shared global
-variables.  To define them, you can use functions listed below:
-
-  void rb_define_variable(const char *name, VALUE *var)
-
-This function defines the variable which is shared by both environments.
-The value of the global variable pointed to by `var' can be accessed
-through Ruby's global variable named `name'.
-
-You can define read-only (from Ruby, of course) variables using the
-function below.
-
-  void rb_define_readonly_variable(const char *name, VALUE *var)
-
-You can defined hooked variables.  The accessor functions (getter and
-setter) are called on access to the hooked variables.
-
-  void rb_define_hooked_variable(constchar *name, VALUE *var,
-				 VALUE (*getter)(), void (*setter)())
-
-If you need to supply either setter or getter, just supply 0 for the
-hook you don't need.  If both hooks are 0, rb_define_hooked_variable()
-works just like rb_define_variable().
-
-  void rb_define_virtual_variable(const char *name,
-				  VALUE (*getter)(), void (*setter)())
-
-This function defines a Ruby global variable without a corresponding C
-variable.  The value of the variable will be set/get only by hooks.
-
-The prototypes of the getter and setter functions are as follows:
-
-  (*getter)(ID id, void *data, struct global_entry* entry);
-  (*setter)(VALUE val, ID id, void *data, struct global_entry* entry);
-
-3.3 Encapsulate C data into a Ruby object
-
-To wrap and objectify a C pointer as a Ruby object (so called
-DATA), use Data_Wrap_Struct().
-
-  Data_Wrap_Struct(klass, mark, free, ptr)
-
-Data_Wrap_Struct() returns a created DATA object.  The klass argument
-is the class for the DATA object.  The mark argument is the function
-to mark Ruby objects pointed by this data.  The free argument is the
-function to free the pointer allocation.  If this is -1, the pointer
-will be just freed.  The functions mark and free will be called from
-garbage collector.
-
-You can allocate and wrap the structure in one step.
-
-  Data_Make_Struct(klass, type, mark, free, sval)
-
-This macro returns an allocated Data object, wrapping the pointer to
-the structure, which is also allocated.  This macro works like:
-
-  (sval = ALLOC(type), Data_Wrap_Struct(klass, mark, free, sval))
-
-Arguments klass, mark, and free work like their counterparts in
-Data_Wrap_Struct().  A pointer to the allocated structure will be
-assigned to sval, which should be a pointer of the type specified.
-
-To retrieve the C pointer from the Data object, use the macro
-Data_Get_Struct().
-
-  Data_Get_Struct(obj, type, sval)
-
-A pointer to the structure will be assigned to the variable sval.
-
-See the example below for details. 
-
-4. Example - Creating dbm extension
-
-OK, here's the example of making an extension library.  This is the
-extension to access DBMs.  The full source is included in the ext/
-directory in the Ruby's source tree.
-
-(1) make the directory
-
-  % mkdir ext/dbm
-
-Make a directory for the extension library under ext directory.
-
-(2) design the library
-
-You need to design the library features, before making it.
-
-(3) write C code.
-
-You need to write C code for your extension library.  If your library
-has only one source file, choosing ``LIBRARY.c'' as a file name is
-preferred.  On the other hand, in case your library has multiple source
-files, avoid choosing ``LIBRARY.c'' for a file name.  It may conflict
-with an intermediate file ``LIBRARY.o'' on some platforms.
-
-Ruby will execute the initializing function named ``Init_LIBRARY'' in
-the library.  For example, ``Init_dbm()'' will be executed when loading
-the library.
-
-Here's the example of an initializing function.
-
---
-Init_dbm()
-{
-    /* define DBM class */
-    cDBM = rb_define_class("DBM", rb_cObject);
-    /* DBM includes Enumerate module */
-    rb_include_module(cDBM, rb_mEnumerable);
-
-    /* DBM has class method open(): arguments are received as C array */
-    rb_define_singleton_method(cDBM, "open", fdbm_s_open, -1);
-
-    /* DBM instance method close(): no args */
-    rb_define_method(cDBM, "close", fdbm_close, 0);
-    /* DBM instance method []: 1 argument */
-    rb_define_method(cDBM, "[]", fdbm_fetch, 1);
-		:
-
-    /* ID for a instance variable to store DBM data */
-    id_dbm = rb_intern("dbm");
-}
---
-
-The dbm extension wraps the dbm struct in the C environment using 
-Data_Make_Struct.
-
---
-struct dbmdata {
-    int  di_size;
-    DBM *di_dbm;
-};
-
-
-obj = Data_Make_Struct(klass, struct dbmdata, 0, free_dbm, dbmp);
---
-
-This code wraps the dbmdata structure into a Ruby object.  We avoid wrapping
-DBM* directly, because we want to cache size information.
-
-To retrieve the dbmdata structure from a Ruby object, we define the
-following macro:
-
---
-#define GetDBM(obj, dbmp) {\
-    Data_Get_Struct(obj, struct dbmdata, dbmp);\
-    if (dbmp->di_dbm == 0) closed_dbm();\
-}
---
-
-This sort of complicated macro does the retrieving and close checking for
-the DBM.
-
-There are three kinds of way to receive method arguments.  First,
-methods with a fixed number of arguments receive arguments like this:
-
---
-static VALUE
-fdbm_delete(obj, keystr)
-    VALUE obj, keystr;
-{
-	:
-}
---
-
-The first argument of the C function is the self, the rest are the
-arguments to the method.
-
-Second, methods with an arbitrary number of arguments receive
-arguments like this:
-
---
-static VALUE
-fdbm_s_open(argc, argv, klass)
-    int argc;
-    VALUE *argv;
-    VALUE klass;
-{
-	:
-    if (rb_scan_args(argc, argv, "11", &file, &vmode) == 1) {
-	mode = 0666;		/* default value */
-    }
-	:
-}
---
-
-The first argument is the number of method arguments, the second
-argument is the C array of the method arguments, and the third
-argument is the receiver of the method.
-
-You can use the function rb_scan_args() to check and retrieve the
-arguments.  For example, "11" means that the method requires at least one
-argument, and at most receives two arguments.
-
-Methods with an arbitrary number of arguments can receive arguments
-by Ruby's array, like this:
-
---
-static VALUE
-fdbm_indexes(obj, args)
-    VALUE obj, args;
-{
-	:
-}
---
-
-The first argument is the receiver, the second one is the Ruby array
-which contains the arguments to the method.
-
-** Notice
-
-GC should know about global variables which refer to Ruby's objects, but
-are not exported to the Ruby world.  You need to protect them by
-
-  void rb_global_variable(VALUE *var)
-
-(4) prepare extconf.rb
-
-If the file named extconf.rb exists, it will be executed to generate
-Makefile.
-
-extconf.rb is the file for checking compilation conditions etc.  You
-need to put
-
-  require 'mkmf'
-
-at the top of the file.  You can use the functions below to check
-various conditions.
-
-  have_library(lib, func): check whether library containing function exists.
-  have_func(func, header): check whether function exists
-  have_header(header): check whether header file exists
-  create_makefile(target): generate Makefile
-
-The value of the variables below will affect the Makefile.
-
-  $CFLAGS: included in CFLAGS make variable (such as -O)
-  $CPPFLAGS: included in CPPFLAGS make variable (such as -I, -D)
-  $LDFLAGS: included in LDFLAGS make variable (such as -L)
-  $objs: list of object file names
-
-Normally, the object files list is automatically generated by searching
-source files, but you must define them explicitly if any sources will
-be generated while building.
-
-If a compilation condition is not fulfilled, you should not call
-``create_makefile''.  The Makefile will not be generated, compilation will
-not be done.
-
-(5) prepare depend (optional)
-
-If the file named depend exists, Makefile will include that file to
-check dependencies.  You can make this file by invoking
-
-  % gcc -MM *.c > depend
-
-It's harmless.  Prepare it.
-
-(6) generate Makefile
-
-Try generating the Makefile by:
-
-  ruby extconf.rb
-
-If the library should be installed under vendor_ruby directory
-instead of site_ruby directory, use --vendor option as follows.
-
-  ruby extconf.rb --vendor
-
-You don't need this step if you put the extension library under the ext
-directory of the ruby source tree.  In that case, compilation of the
-interpreter will do this step for you.
-
-(7) make
-
-Type
-
-  make
-
-to compile your extension.  You don't need this step either if you have
-put the extension library under the ext directory of the ruby source tree.
-
-(8) debug
-
-You may need to rb_debug the extension.  Extensions can be linked
-statically by adding the directory name in the ext/Setup file so that
-you can inspect the extension with the debugger.
-
-(9) done, now you have the extension library
-
-You can do anything you want with your library.  The author of Ruby
-will not claim any restrictions on your code depending on the Ruby API.
-Feel free to use, modify, distribute or sell your program.

-
-** Types
-
- VALUE
-
-The type for the Ruby object.  Actual structures are defined in ruby.h,
-such as struct RString, etc.  To refer the values in structures, use
-casting macros like RSTRING(obj).
-
-** Variables and constants
-
- Qnil
-
-const: nil object
-
- Qtrue
-
-const: true object(default true value)
-
- Qfalse
-
-const: false object
-
-** C pointer wrapping
-
- Data_Wrap_Struct(VALUE klass, void (*mark)(), void (*free)(), void *sval)
-
-Wrap a C pointer into a Ruby object.  If object has references to other
-Ruby objects, they should be marked by using the mark function during
-the GC process.  Otherwise, mark should be 0.  When this object is no
-longer referred by anywhere, the pointer will be discarded by free
-function.
-
- Data_Make_Struct(klass, type, mark, free, sval)
-
-This macro allocates memory using malloc(), assigns it to the variable
-sval, and returns the DATA encapsulating the pointer to memory region.
-
- Data_Get_Struct(data, type, sval)
-
-This macro retrieves the pointer value from DATA, and assigns it to
-the variable sval. 
-
-** Checking data types

-
- void rb_define_virtual_variable(const char *name,
-				 VALUE (*getter)(), VALUE (*setter)())
-
-Defines a virtual variable, whose behavior is defined by a pair of C
-functions.  The getter function is called when the variable is
-referenced.  The setter function is called when the variable is set to a
-value.  The prototype for getter/setter functions are:
-
-	VALUE getter(ID id)
-	void setter(VALUE val, ID id)
-
-The getter function must return the value for the access.
-
- void rb_define_hooked_variable(const char *name, VALUE *var,
-				VALUE (*getter)(), VALUE (*setter)())
-
-Defines hooked variable.  It's a virtual variable with a C variable.  
-The getter is called as
-
-	VALUE getter(ID id, VALUE *var)
-
-returning a new value.  The setter is called as

-
-** Method Definition
-
- rb_define_method(VALUE klass, const char *name, VALUE (*func)(), int argc)
-
-Defines a method for the class.  func is the function pointer.  argc
-is the number of arguments.  if argc is -1, the function will receive

-
-Retrieve argument from argc, argv.  The fmt is the format string for
-the arguments, such as "12" for 1 non-optional argument, 2 optional
-arguments.  If `*' appears at the end of fmt, it means the rest of
-the arguments are assigned to the corresponding variable, packed in
-an array.
-
-** Invoking Ruby method
-
- VALUE rb_funcall(VALUE recv, ID mid, int narg, ...)
-
-Invokes a method.  To retrieve mid from a method name, use rb_intern().

-
- char *rb_class2name(VALUE klass)
-
-Returns the name of the class.
-
- int rb_respond_to(VALUE object, ID id)
-
-Returns true if the object responds to the message specified by id.
-
-** Instance Variables
-
- VALUE rb_iv_get(VALUE obj, const char *name)

-
-** Control Structure
-
- VALUE rb_iterate(VALUE (*func1)(), void *arg1, VALUE (*func2)(), void *arg2)
-
-Calls the function func1, supplying func2 as the block.  func1 will be
-called with the argument arg1.  func2 receives the value from yield as
-the first argument, arg2 as the second argument.
- 
- VALUE rb_yield(VALUE val)
-
-Evaluates the block with value val.
-
- VALUE rb_rescue(VALUE (*func1)(), void *arg1, VALUE (*func2)(), void *arg2)
-
-Calls the function func1, with arg1 as the argument.  If an exception
-occurs during func1, it calls func2 with arg2 as the argument.  The
-return value of rb_rescue() is the return value from func1 if no
-exception occurs, from func2 otherwise.
-
- VALUE rb_ensure(VALUE (*func1)(), void *arg1, void (*func2)(), void *arg2)
-
-Calls the function func1 with arg1 as the argument, then calls func2

-
-Raises a class exception.  The fmt is a format string just like printf().
-
- void rb_fatal(const char *fmt, ...)
-
-Raises a fatal error, terminates the interpreter.  No exception handling
-will be done for fatal errors, but ensure blocks will be executed.
-
- void rb_bug(const char *fmt, ...)
-
-Terminates the interpreter immediately.  This function should be
-called under the situation caused by the bug in the interpreter.  No
-exception handling nor ensure execution will be done.

- 				      VALUE self, ID id, VALUE klass)
-
- int rb_remove_event_hook(rb_event_hook_func_t func)

-
-Checks whether macro is defined with header.  Returns true if the macro
-is defined.
-
- have_library(lib, func)
-
-Checks whether the library exists, containing the specified function.
-Returns true if the library exists.
-
- find_library(lib, func, path...)
-
-Checks whether a library which contains the specified function exists in
-path.  Returns true if the library exists.
-
- have_func(func, header)
-
-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().
-
- have_var(var, header)
-
-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().
-
- have_header(header)
-
-Checks whether header exists.  Returns true if the header file exists.
-
- find_header(header, path...)
-
-Checks whether header exists in path.  Returns true if the header file
-exists.
-
- have_struct_member(type, member, header)
-
-Checks whether type has member with header.  Returns true if the type
-is defined and has the member.
-
- have_type(type, header, opt)
-
-Checks whether type is defined with header.  Returns true if the type
-is defined.
-
- check_sizeof(type, header)
-
-Checks the size of type in char with header.  Returns the size if the
-type is defined, otherwise nil.
-
- create_makefile(target)
-
-Generates the Makefile for the extension library.  If you don't invoke
-this method, the compilation will not be done.
-
- find_executable(bin, path)
-
-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.
-
- with_config(withval[, default=nil])
-
-Parses the command line options and returns the value specified by
---with-<withval>.
-
- enable_config(config, *defaults)
- disable_config(config, *defaults)
-
-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.
-
- dir_config(target[, default_dir])
- dir_config(target[, default_include, default_lib])
-
-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]).
-
- pkg_config(pkg)
-
-Obtains the information for pkg by pkg-config command.  The actual
-command name can be overriden by --with-pkg-config command line
-option.

+# Rubyとは
+
+Rubyはシンプルかつ強力なオブジェクト指向スクリプト言語です． Rubyは純粋なオブジェクト指向言語として設計されているので，
+オブジェクト指向プログラミングを手軽に行う事が出来ます．もちろん普通の手続き型のプログラミングも可能です．
+
+Rubyはテキスト処理関係の能力などに優れ，Perlと同じくらい強力です．さらにシンプルな文法と，
+例外処理やイテレータなどの機構によって，より分かりやすいプログラミングが出来ます．
+
+## Rubyの特長
+
+*   シンプルな文法
+*   普通のオブジェクト指向機能(クラス，メソッドコールなど)
+*   特殊なオブジェクト指向機能(Mixin, 特異メソッドなど)
+*   演算子オーバーロード
+*   例外処理機能
+*   イテレータとクロージャ
+*   ガーベージコレクタ
+*   ダイナミックローディング (アーキテクチャによる)
+*   移植性が高い．多くのUnix-like/POSIX互換プラットフォーム上で動くだけでなく，Windows， macOS，
+    Haikuなどの上でも動く cf.
+    https://github.com/ruby/ruby/blob/trunk/doc/contributing.rdoc#platform-maintainers
+
+
+## 入手法
+
+サードパーティーツールを使った方法を含むRubyのインストール方法の一覧は
+
+https://www.ruby-lang.org/ja/downloads/
+
+を参照してください．
+
+### Subversionで
+
+開発先端のソースコードは次のコマンドで取得できます．
+
+    $ svn co https://svn.ruby-lang.org/repos/ruby/trunk/ ruby
+
+他に開発中のブランチの一覧は次のコマンドで見られます．
+
+    $ svn ls https://svn.ruby-lang.org/repos/ruby/branches/
+
+### Gitで
+
+SubversionのミラーをGitHubに公開しています． 以下のコマンドでリポジトリを取得できます．
+
+    $ git clone https://github.com/ruby/ruby.git
+
+## ホームページ
+
+RubyのホームページのURLは
+
+https://www.ruby-lang.org/
+
+です．
+
+## メーリングリスト
+
+Rubyのメーリングリストがあります．参加希望の方は
+
+mailto:ruby-list-request@ruby-lang.org
+
+まで本文に
+
+    subscribe
+
+と書いて送って下さい．
+
+Ruby開発者向けメーリングリストもあります．こちらではrubyのバグ，将来の仕様拡張など実装上の問題について議論されています． 参加希望の方は
+
+mailto:ruby-dev-request@ruby-lang.org
+
+までruby-listと同様の方法でメールしてください．
+
+Ruby拡張モジュールについて話し合うruby-extメーリングリストと数学関係の話題について話し合うruby-mathメーリングリストと
+英語でrubyについて話し合うruby-talkメーリングリストもあります．参加方法はどれも同じです．
+
+## コンパイル・インストール
+
+以下の手順で行ってください．
+
+1.  もし `configure` ファイルが見つからない，もしくは `configure.ac` より古いようなら， `autoconf` を実行して
+    新しく `configure` を生成する
+
+2.  `configure` を実行して `Makefile` などを生成する
+
+    環境によってはデフォルトのCコンパイラ用オプションが付きます． `configure` オプションで `optflags=..`
+    `warnflags=..` 等で上書きできます．
+
+3.  (必要ならば)`defines.h` を編集する
+
+    多分，必要無いと思います．
+
+4.  (必要ならば)`ext/Setup` に静的にリンクする拡張モジュールを指定する
+
+    `ext/Setup` に記述したモジュールは静的にリンクされます．
+
+    ダイナミックローディングをサポートしていないアーキテクチャでは `Setup` の1行目の「`option nodynamic`」という行のコ
+    メントを外す必要があります．また，このアーキテクチャで拡張モジュールを利用するためには，あらかじめ静的にリンクをしておく必要があります．
+
+5.  `make` を実行してコンパイルする
+
+6.  `make check`でテストを行う．
+
+    「`check succeeded`」と表示されれば成功です．ただしテストに成功しても完璧だと保証されている訳ではありません．
+
+7.  `make install`
+
+    以下のディレクトリを作って，そこにファイルをインストー ルします．
+
+    *   `${DESTDIR}${prefix}/bin`
+    *   `${DESTDIR}${prefix}/include/ruby-${MAJOR}.${MINOR}.${TEENY}`
+    *   `${DESTDIR}${prefix}/include/ruby-${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}`
+    *   `${DESTDIR}${prefix}/lib`
+    *   `${DESTDIR}${prefix}/lib/ruby`
+    *   `${DESTDIR}${prefix}/lib/ruby/${MAJOR}.${MINOR}.${TEENY}`
+    *   `${DESTDIR}${prefix}/lib/ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}`
+    *   `${DESTDIR}${prefix}/lib/ruby/site_ruby`
+    *   `${DESTDIR}${prefix}/lib/ruby/site_ruby/${MAJOR}.${MINOR}.${TEENY}`
+    *   `${DESTDIR}${prefix}/lib/ruby/site_ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}`
+    *   `${DESTDIR}${prefix}/lib/ruby/vendor_ruby`
+    *   `${DESTDIR}${prefix}/lib/ruby/vendor_ruby/${MAJOR}.${MINOR}.${TEENY}`
+    *   `${DESTDIR}${prefix}/lib/ruby/vendor_ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}`
+    *   `${DESTDIR}${prefix}/lib/ruby/gems/${MAJOR}.${MINOR}.${TEENY}`
+    *   `${DESTDIR}${prefix}/share/man/man1`
+    *   `${DESTDIR}${prefix}/share/ri/${MAJOR}.${MINOR}.${TEENY}/system`
+
+
+    RubyのAPIバージョンが'*x.y.z*'であれば，`${MAJOR}`は
+    '*x*'で，`${MINOR}`は'*y*'，`${TEENY}`は'*z*'です．
+
+    **注意**: APIバージョンの `teeny` は，Rubyプログラムのバージョンとは異なることがあります．
+
+    `root` で作業する必要があるかもしれません．
+
+
+もし，コンパイル時にエラーが発生した場合にはエラーのログとマシン，OSの種類を含むできるだけ詳しいレポートを作者に送って下さると他の方のためにもなります．
+
+## 移植
+
+UNIXであれば `configure` がほとんどの差異を吸収してくれるはずですが，思わぬ見落としがあった場合(ある事が多い)，作者にその
+ことを報告すれば，解決できる可能性があります．
+
+アーキテクチャにもっとも依存するのはGC部です．RubyのGCは対象
+のアーキテクチャが`setjmp()`または`getcontext()`によって全てのレジスタを `jmp_buf` や `ucontext_t`
+に格納することと， `jmp_buf` や `ucontext_t` とスタックが32bitアラインメントされていることを仮定
+しています．特に前者が成立しない場合の対応は非常に困難でしょう． 後者の解決は比較的簡単で， `gc.c` でスタックをマークしている
+部分にアラインメントのバイト数だけずらしてマークするコードを追加するだけで済みます．`defined(__mc68000__)`で括られてい
+る部分を参考にしてください．
+
+レジスタウィンドウを持つCPUでは，レジスタウィンドウをスタックにフラッシュするアセンブラコードを追加する必要があるかもしれません．

+# What's Ruby
+
+Ruby is the interpreted scripting language for quick and easy object-oriented
+programming. It has many features to process text files and to do system
+management tasks (as in Perl). It is simple, straight-forward, and
+extensible.
+
+## Features of Ruby
+
+*   Simple Syntax
+*   **Normal** Object-oriented Features (e.g. class, method calls)
+*   **Advanced** Object-oriented Features (e.g. mix-in, singleton-method)
+*   Operator Overloading
+*   Exception Handling
+*   Iterators and Closures
+*   Garbage Collection
+*   Dynamic Loading of Object Files (on some architectures)
+*   Highly Portable (works on many Unix-like/POSIX compatible platforms as
+    well as Windows, macOS, Haiku, etc.) cf.
+    https://github.com/ruby/ruby/blob/trunk/doc/contributing.rdoc#platform-maintainers
+
+
+## How to get Ruby
+
+For a complete list of ways to install Ruby, including using third-party tools
+like rvm, see:
+
+https://www.ruby-lang.org/en/downloads/
+
+The trunk of the Ruby source tree can be checked out with the following
+command:
+
+    $ svn co https://svn.ruby-lang.org/repos/ruby/trunk/ ruby
+
+Or if you are using git then use the following command:
+
+    $ git clone https://github.com/ruby/ruby.git
+
+There are some other branches under development. Try the following command
+to see the list of branches:
+
+    $ svn ls https://svn.ruby-lang.org/repos/ruby/branches/
+
+Or if you are using git then use the following command:
+
+    $ git ls-remote https://github.com/ruby/ruby.git
+
+## Ruby home page
+
+The URL of the Ruby home page is:
+
+https://www.ruby-lang.org/
+
+## Mailing list
+
+There is a mailing list to talk about Ruby. To subscribe to this list, please
+send the following phrase:
+
+    subscribe
+
+in the mail body (not subject) to the address
+<ruby-talk-request@ruby-lang.org>.
+
+## How to compile and install
+
+This is what you need to do to compile and install Ruby:
+
+1.  If you want to use Microsoft Visual C++ to compile Ruby, read
+    [win32/README.win32](win32/README.win32) instead of this document.
+
+2.  If `./configure` does not exist or is older than `configure.ac`, run
+    `autoconf` to (re)generate configure.
+
+3.  Run `./configure`, which will generate `config.h` and `Makefile`.
+
+    Some C compiler flags may be added by default depending on your
+    environment. Specify `optflags=..` and `warnflags=..` as necessary to
+    override them.
+
+4.  Edit `defines.h` if you need. Usually this step will not be needed.
+
+5.  Remove comment mark(`#`) before the module names from `ext/Setup` (or add
+    module names if not present), if you want to link modules statically.
+
+    If you don't want to compile non static extension modules (probably on
+    architectures which do not allow dynamic loading), remove comment mark
+    from the line "`#option nodynamic`" in `ext/Setup`.
+
+    Usually this step will not be needed.
+
+6.  Run `make`.
+
+    * On Mac, set RUBY\_CODESIGN environment variable with a signing identity.
+      It uses the identity to sign `ruby` binary. See also codesign(1).
+
+7.  Optionally, run '`make check`' to check whether the compiled Ruby
+    interpreter works well. If you see the message "`check succeeded`", your
+    Ruby works as it should (hopefully).
+
+8.  Optionally, run `make update-gems` and `make extract-gems`.
+
+    If you want to install bundled gems, run `make update-gems` and
+    `make extract-gems` before running `make install`.
+
+9.  Run '`make install`'.
+
+    This command will create the following directories and install files into
+    them.
+
+    *   `${DESTDIR}${prefix}/bin`
+    *   `${DESTDIR}${prefix}/include/ruby-${MAJOR}.${MINOR}.${TEENY}`
+    *   `${DESTDIR}${prefix}/include/ruby-${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}`
+    *   `${DESTDIR}${prefix}/lib`
+    *   `${DESTDIR}${prefix}/lib/ruby`
+    *   `${DESTDIR}${prefix}/lib/ruby/${MAJOR}.${MINOR}.${TEENY}`
+    *   `${DESTDIR}${prefix}/lib/ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}`
+    *   `${DESTDIR}${prefix}/lib/ruby/site_ruby`
+    *   `${DESTDIR}${prefix}/lib/ruby/site_ruby/${MAJOR}.${MINOR}.${TEENY}`
+    *   `${DESTDIR}${prefix}/lib/ruby/site_ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}`
+    *   `${DESTDIR}${prefix}/lib/ruby/vendor_ruby`
+    *   `${DESTDIR}${prefix}/lib/ruby/vendor_ruby/${MAJOR}.${MINOR}.${TEENY}`
+    *   `${DESTDIR}${prefix}/lib/ruby/vendor_ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}`
+    *   `${DESTDIR}${prefix}/lib/ruby/gems/${MAJOR}.${MINOR}.${TEENY}`
+    *   `${DESTDIR}${prefix}/share/man/man1`
+    *   `${DESTDIR}${prefix}/share/ri/${MAJOR}.${MINOR}.${TEENY}/system`
+
+
+    If Ruby's API version is '*x.y.z*', the `${MAJOR}` is '*x*', the
+    `${MINOR}` is '*y*', and the `${TEENY}` is '*z*'.
+
+    **NOTE**: teeny of the API version may be different from one of Ruby's
+    program version
+
+    You may have to be a super user to install Ruby.
+
+
+If you fail to compile Ruby, please send the detailed error report with the
+error log and machine/OS type, to help others.
+
+Some extension libraries may not get compiled because of lack of necessary
+external libraries and/or headers, then you will need to run '`make distclean-ext`'
+to remove old configuration after installing them in such case.

+ *
+ *  In find-any mode (this behaves like libc's bsearch(3)), the block
+ *  must always 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

+/*
+ *  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}    #=> [{}, {}, {}, {}]
+ *     Array.new(4) {|i| i.to_s } #=> ["0", "1", "2", "3"]
+ *
+ *  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

+# ruby/benchmark
+
+This directory has benchmark definitions to be run with
+[benchmark\_driver.gem](https://github.com/benchmark-driver/benchmark-driver).
+
+## Normal usage
+
+Execute `gem install benchmark_driver` and run a command like:
+
+```bash
+# Run a benchmark script with the ruby in the $PATH
+benchmark-driver benchmark/app_fib.rb
+
+# Run benchmark scripts with multiple Ruby executables or options
+benchmark-driver benchmark/*.rb -e /path/to/ruby -e '/path/to/ruby --jit'
+
+# Or compare Ruby versions managed by rbenv
+benchmark-driver benchmark/*.rb --rbenv '2.5.1;2.6.0-preview2 --jit'
+
+# You can collect many metrics in many ways
+benchmark-driver benchmark/*.rb --runner memory --output markdown
+
+# Some are defined with YAML for complex setup or accurate measurement
+benchmark-driver benchmark/*.yml
+```
+
+See also:
+
+```console
+Usage: benchmark-driver [options] RUBY|YAML...
+    -r, --runner TYPE                Specify runner type: ips, time, memory, once (default: ips)
+    -o, --output TYPE                Specify output type: compare, simple, markdown, record (default: compare)
+    -e, --executables EXECS          Ruby executables (e1::path1 arg1; e2::path2 arg2;...)
+        --rbenv VERSIONS             Ruby executables in rbenv (x.x.x arg1;y.y.y arg2;...)
+        --repeat-count NUM           Try benchmark NUM times and use the fastest result or the worst memory usage
+        --repeat-result TYPE         Yield "best", "average" or "worst" result with --repeat-count (default: best)
+        --bundler                    Install and use gems specified in Gemfile
+        --filter REGEXP              Filter out benchmarks with given regexp
+        --run-duration SECONDS       Warmup estimates loop_count to run for this duration (default: 3)
+    -v, --verbose                    Verbose mode. Multiple -v options increase visilibity (max: 2)
+```
+
+## make benchmark
+
+Using `make benchmark`, `make update-benchmark-driver` automatically downloads
+the supported version of benchmark\_driver, and it runs benchmarks with the downloaded
+benchmark\_driver.
+
+```bash
+# Run all benchmarks with the ruby in the $PATH and the built ruby
+make benchmark
+
+# Or compare with specific ruby binary
+make benchmark COMPARE_RUBY="/path/to/ruby --jit"
+
+# Run vm1 benchmarks
+make benchmark ITEM=vm1
+
+# Run some limited benchmarks in ITEM-matched files
+make benchmark ITEM=vm1 OPTS=--filter=block
+
+# You can specify the benchmark by an exact filename instead of using the default argument:
+# ARGS = $$(find $(srcdir)/benchmark -maxdepth 1 -name '*$(ITEM)*.yml' -o -name '*$(ITEM)*.rb')
+make benchmark ARGS=../benchmark/erb_render.yml
+
+# You can specify any option via $OPTS
+make benchmark OPTS="--help"
+
+# With `make benchmark`, some special runner plugins are available:
+#   -r peak, -r size, -r total, -r utime, -r stime, -r cutime, -r cstime
+make benchmark ITEM=vm2_bigarray OPTS="-r peak"
+```
