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

-
-	* signal.c  (rb_atomic_t): GCC (of  at least  recent versions)
-	  has  ubiquitous  support  for  atomic operations.   On  that
-	  compiler a C program can  issue a memory barrier using these
-	  dedicated  instructions.  According to  the GCC  manual they
-	  cargo culted  this feature form  the Itanium ABI  so chances
-	  are that  other compilers  could also support  this feature.

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

+      TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+      1. Definitions.
+
+         "License" shall mean the terms and conditions for use, reproduction,
+         and distribution as defined by Sections 1 through 9 of this document.
+
+         "Licensor" shall mean the copyright owner or entity authorized by
+         the copyright owner that is granting the License.
+
+         "Legal Entity" shall mean the union of the acting entity and all
+         other entities that control, are controlled by, or are under common
+         control with that entity. For the purposes of this definition,
+         "control" means (i) the power, direct or indirect, to cause the
+         direction or management of such entity, whether by contract or
+         otherwise, or (ii) ownership of fifty percent (50%) or more of the
+         outstanding shares, or (iii) beneficial ownership of such entity.
+
+         "You" (or "Your") shall mean an individual or Legal Entity
+         exercising permissions granted by this License.
+
+         "Source" form shall mean the preferred form for making modifications,
+         including but not limited to software source code, documentation
+         source, and configuration files.
+
+         "Object" form shall mean any form resulting from mechanical
+         transformation or translation of a Source form, including but
+         not limited to compiled object code, generated documentation,
+         and conversions to other media types.
+
+         "Work" shall mean the work of authorship, whether in Source or
+         Object form, made available under the License, as indicated by a
+         copyright notice that is included in or attached to the work
+         (an example is provided in the Appendix below).
+
+         "Derivative Works" shall mean any work, whether in Source or Object
+         form, that is based on (or derived from) the Work and for which the
+         editorial revisions, annotations, elaborations, or other modifications
+         represent, as a whole, an original work of authorship. For the purposes
+         of this License, Derivative Works shall not include works that remain
+         separable from, or merely link (or bind by name) to the interfaces of,
+         the Work and Derivative Works thereof.
+
+         "Contribution" shall mean any work of authorship, including
+         the original version of the Work and any modifications or additions
+         to that Work or Derivative Works thereof, that is intentionally
+         submitted to Licensor for inclusion in the Work by the copyright owner
+         or by an individual or Legal Entity authorized to submit on behalf of
+         the copyright owner. For the purposes of this definition, "submitted"
+         means any form of electronic, verbal, or written communication sent
+         to the Licensor or its representatives, including but not limited to
+         communication on electronic mailing lists, source code control systems,
+         and issue tracking systems that are managed by, or on behalf of, the
+         Licensor for the purpose of discussing and improving the Work, but
+         excluding communication that is conspicuously marked or otherwise
+         designated in writing by the copyright owner as "Not a Contribution."
+
+         "Contributor" shall mean Licensor and any individual or Legal Entity
+         on behalf of whom a Contribution has been received by Licensor and
+         subsequently incorporated within the Work.
+
+      2. Grant of Copyright License. Subject to the terms and conditions of
+         this License, each Contributor hereby grants to You a perpetual,
+         worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+         copyright license to reproduce, prepare Derivative Works of,
+         publicly display, publicly perform, sublicense, and distribute the
+         Work and such Derivative Works in Source or Object form.
+
+      3. Grant of Patent License. Subject to the terms and conditions of
+         this License, each Contributor hereby grants to You a perpetual,
+         worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+         (except as stated in this section) patent license to make, have made,
+         use, offer to sell, sell, import, and otherwise transfer the Work,
+         where such license applies only to those patent claims licensable
+         by such Contributor that are necessarily infringed by their
+         Contribution(s) alone or by combination of their Contribution(s)
+         with the Work to which such Contribution(s) was submitted. If You
+         institute patent litigation against any entity (including a
+         cross-claim or counterclaim in a lawsuit) alleging that the Work
+         or a Contribution incorporated within the Work constitutes direct
+         or contributory patent infringement, then any patent licenses
+         granted to You under this License for that Work shall terminate
+         as of the date such litigation is filed.
+
+      4. Redistribution. You may reproduce and distribute copies of the
+         Work or Derivative Works thereof in any medium, with or without
+         modifications, and in Source or Object form, provided that You
+         meet the following conditions:
+
+         a.  You must give any other recipients of the Work or
+             Derivative Works a copy of this License; and
+
+         b.  You must cause any modified files to carry prominent notices
+             stating that You changed the files; and
+
+         c.  You must retain, in the Source form of any Derivative Works
+             that You distribute, all copyright, patent, trademark, and
+             attribution notices from the Source form of the Work,
+             excluding those notices that do not pertain to any part of
+             the Derivative Works; and
+
+         d.  If the Work includes a "NOTICE" text file as part of its
+             distribution, then any Derivative Works that You distribute must
+             include a readable copy of the attribution notices contained
+             within such NOTICE file, excluding those notices that do not
+             pertain to any part of the Derivative Works, in at least one
+             of the following places: within a NOTICE text file distributed
+             as part of the Derivative Works; within the Source form or
+             documentation, if provided along with the Derivative Works; or,
+             within a display generated by the Derivative Works, if and
+             wherever such third-party notices normally appear. The contents
+             of the NOTICE file are for informational purposes only and
+             do not modify the License. You may add Your own attribution
+             notices within Derivative Works that You distribute, alongside
+             or as an addendum to the NOTICE text from the Work, provided
+             that such additional attribution notices cannot be construed
+             as modifying the License.
+
+         You may add Your own copyright statement to Your modifications and
+         may provide additional or different license terms and conditions
+         for use, reproduction, or distribution of Your modifications, or
+         for any such Derivative Works as a whole, provided Your use,
+         reproduction, and distribution of the Work otherwise complies with
+         the conditions stated in this License.
+
+      5. Submission of Contributions. Unless You explicitly state otherwise,
+         any Contribution intentionally submitted for inclusion in the Work
+         by You to the Licensor shall be under the terms and conditions of
+         this License, without any additional terms or conditions.
+         Notwithstanding the above, nothing herein shall supersede or modify
+         the terms of any separate license agreement you may have executed
+         with Licensor regarding such Contributions.
+
+      6. Trademarks. This License does not grant permission to use the trade
+         names, trademarks, service marks, or product names of the Licensor,
+         except as required for reasonable and customary use in describing the
+         origin of the Work and reproducing the content of the NOTICE file.
+
+      7. Disclaimer of Warranty. Unless required by applicable law or
+         agreed to in writing, Licensor provides the Work (and each
+         Contributor provides its Contributions) on an "AS IS" BASIS,
+         WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+         implied, including, without limitation, any warranties or conditions
+         of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+         PARTICULAR PURPOSE. You are solely responsible for determining the
+         appropriateness of using or redistributing the Work and assume any
+         risks associated with Your exercise of permissions under this License.
+
+      8. Limitation of Liability. In no event and under no legal theory,
+         whether in tort (including negligence), contract, or otherwise,
+         unless required by applicable law (such as deliberate and grossly
+         negligent acts) or agreed to in writing, shall any Contributor be
+         liable to You for damages, including any direct, indirect, special,
+         incidental, or consequential damages of any character arising as a
+         result of this License or out of the use or inability to use the
+         Work (including but not limited to damages for loss of goodwill,
+         work stoppage, computer failure or malfunction, or any and all
+         other commercial damages or losses), even if such Contributor
+         has been advised of the possibility of such damages.
+
+      9. Accepting Warranty or Additional Liability. While redistributing
+         the Work or Derivative Works thereof, You may choose to offer,
+         and charge a fee for, acceptance of support, warranty, indemnity,
+         or other liability obligations and/or rights consistent with this
+         License. However, in accepting such obligations, You may act only
+         on Your own behalf and on Your sole responsibility, not on behalf
+         of any other Contributor, and only if You agree to indemnify,
+         defend, and hold each Contributor harmless for any liability
+         incurred by, or claims asserted against, such Contributor by reason
+         of your accepting any such warranty or additional liability.

-
-=== C API updates
-
-* rb_scan_args() is enhanced with support for option hash argument
-  extraction.
-
-* ruby_vm_at_exit() added.  This enables extension libs to hook a VM
-  termination.
-
-=== Library updates (outstanding ones only)
-
-* builtin classes
-
-  * ARGF
-    * new methods:
-      * ARGF.print
-      * ARGF.printf
-      * ARGF.putc
-      * ARGF.puts
-      * ARGF.read_nonblock
-      * ARGF.to_write_io
-      * ARGF.write
-
-  * Array
-    * extended method:
-      * Array#pack supports endian modifiers
-
-  * Encoding
-    * new encodings:
-      * CP950
-      * CP951
-      * UTF-16
-      * UTF-32
-    * change alias:
-      * SJIS is Windows-31J
-
-  * File
-    * new constant:
-      * File::NULL
-        name of NULL device.
-
-  * IO
-    * extended method:
-      * IO#putc supports multibyte characters
-    * new method:
-      * IO#advise
-
-  * Kernel
-    * Kernel#respond_to? now returns false for protected methods.
-    * move #__id__ to BasicObject.
-
-  * Module
-    * new methods:
-      * Module#private_constant
-      * Module#public_constant
-
-  * String
-    * extended method:
-      * String#unpack supports endian modifiers
-    * new method:
-      * String#prepend

-
-* zlib
-  * new methods:
-    * Zlib.deflate
-    * Zlib.inflate
-

+# NEWS for Ruby 4.1.0
+
+This document is a list of user-visible feature changes
+since the **4.0.0** release, except for bug fixes.
+
+Note that each entry is kept to a minimum, see links for details.
+
+## Language changes
+
+* `Module#clone` and `Module#dup` no longer rewrite the lexical scope of
+  copied methods. Constants and class variables resolve through the
+  original class, consistent with inheritance and mixins.
+  [[Feature #21981]]
+
+## Core classes updates
+
+Note: We're only listing outstanding class updates.
+
+* Array
+
+    * `Array#pack` accepts a new format `R` and `r` for unpacking unsigned
+      and signed LEB128 encoded integers. [[Feature #21785]]
+    * `Array#pack` accepts a new format `^` that returns the current offset.
+      Useful when combined with variable width formats like LEB128. [[Feature #21796]]
+
+* ENV
+
+    * `ENV.fetch_values` is added. It returns an array of values for the
+      given names, raising `KeyError` for missing names unless a block is
+      given. [[Feature #21781]]
+
+* Kernel
+
+    * `Kernel#autoload_relative` and `Module#autoload_relative` are added.
+      These methods work like `autoload`, but resolve the file path relative
+      to the file where the method is called, similar to `require_relative`.
+      This makes it easier to autoload constants from files in the same
+      directory without hardcoding absolute paths or manipulating `$LOAD_PATH`.
+      [[Feature #15330]]
+
+* MatchData
+
+    * `MatchData#integer_at` is added.  It converts the matched substring to
+      integer and return the result.  [[Feature #21932]]
+
+* Regexp
+
+    * All instances of `Regexp` are now frozen, not just literals.
+      Subclasses of `Regexp` are not frozen for compatibility.
+      [[Feature #8948]]
+
+* Set
+
+    * A deprecated behavior, `Set#to_set`, `Range#to_set`, and
+      `Enumerable#to_set` accepting arguments, was removed.  [[Feature #21390]]
+

+### RubyGems and Bundler
+
+Ruby 4.0 bundled RubyGems and Bundler version 4. see the following links for details.
+
+## Supported platforms
+
+## Compatibility issues
+
+## Stdlib compatibility issues
+
+## C API updates
+
+### Embedded TypedData
+
+* The `RUBY_TYPED_EMBEDDABLE` flag is now public and documented and can be used by C extensions.
+  It allows allocating C structs directly into Ruby object slots, which reduces pointer chasing,
+  and in some case memory usage.
+  See the C extension documentation for details. [[Feature #21853]]
+
+* Added new C23 inspired allocator functions, that takes the previous memory size.
+  This allow the Ruby GC to better keep track of memory usage, improving its heuristics.
+  It also improves the performance of system allocators that support C23 `free_sized`.
+
+  However, it is important to note that passing an incorrect size to these function is undefined
+  behavior and may result in crashes or memory leaks.
+
+  - `ruby_xfree_sized(void *ptr, size_t size)`
+  - `ruby_xrealloc_sized(void *ptr, size_t newsiz, size_t oldsiz)`
+  - `ruby_xrealloc2_sized(void *ptr, size_t newelems, size_t newsiz, size_t oldelems)`
+
+  [[Feature #21861]]
+
+### Removed APIs
+
+The following APIs, which have been deprecated for many years, are removed.
+[[Feature #21768]]
+
+* old postponed job functions,
+* untyped data object type/functions,
+* old APIs to allocate a data object,
+* taintedness/trustedness enums/macros,
+* `rb_gc_force_recycle` function,
+* `rb_iterate` function,
+* and some functions and constants for internal use.
+
+## Implementation improvements
+
+### Ractor
+
+A lot of work has gone into making Ractors more stable, performant, and usable. These improvements bring Ractor implementation closer to leaving experimental status.

-* What's Ruby
-
-Ruby is the interpreted scripting language for quick and
-easy object-oriented programming.  It has many features to
-process text files and to do system management tasks (as in
-Perl).  It is simple, straight-forward, and extensible.
-
-
-* Features of Ruby
-
-  + Simple Syntax
-  + *Normal* Object-Oriented features(ex. class, method calls)
-  + *Advanced* Object-Oriented features(ex. Mix-in, Singleton-method)
-  + Operator Overloading
-  + Exception Handling
-  + Iterators and Closures
-  + Garbage Collection
-  + Dynamic Loading of Object files(on some architecture)
-  + Highly Portable (works on many Unix-like/POSIX compatible platforms
-    as well as Windows, Mac OS X, BeOS etc.)
-    cf. http://redmine.ruby-lang.org/wiki/ruby-19/SupportedPlatforms
-
-
-* How to get Ruby
-
-The Ruby distribution files can be found in the following FTP site:
-
-  ftp://ftp.ruby-lang.org/pub/ruby/
-
-The trunk of the Ruby source tree can be checked out with the
-following command:
-
-  $ svn co http://svn.ruby-lang.org/repos/ruby/trunk/ ruby
-
-There are some other branches under development.  Try the following
-command and see the list of branches:
-
-  $ svn ls http://svn.ruby-lang.org/repos/ruby/branches/
-
-
-* Ruby home-page
-
-The URL of the Ruby home-page is:
-
-   http://www.ruby-lang.org/
-
-
-* Mailing list
-
-There is a mailing list to talk about Ruby.
-To subscribe this list, please send the following phrase
-
-	subscribe YourFirstName YourFamilyName
-e.g.
-        subscribe Joseph Smith
-
-in the mail body (not subject) to the address <ruby-talk-ctl@ruby-lang.org>.
-
-
-* How to compile and install
-
-This is what you need to do to compile and install Ruby:
-
-  1. If ./configure does not exist or is older than configure.in,
-     run autoconf to (re)generate configure.
-
-  2. Run ./configure, which will generate config.h and Makefile.
-
-     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'
-
-     This command will create following directories and install files
-     onto them.
-
-       * ${DESTDIR}${prefix}/bin
-       * ${DESTDIR}${prefix}/include/ruby-${MAJOR}.${MINOR}.${TEENY}
-       * ${DESTDIR}${prefix}/include/ruby-${MAJOR}.${MINOR}.${TEENY}/${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.
-
-

-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_HASH		associative array
-	T_STRUCT	(Ruby) structure
-	T_BIGNUM	multi precision integer
-	T_FIXNUM	Fixnum(31bit or 63bit integer)
-	T_COMPLEX       complex number
-	T_RATIONAL      rational number
-	T_FILE		IO
-	T_TRUE		true
-	T_FALSE		false
-	T_DATA		data
-	T_SYMBOL        symbol
-
-In addition, there are several other types used internally:
-
-	T_ICLASS
-	T_MATCH
-	T_UNDEF
-	T_NODE
-	T_ZOMBIE
-
-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, false, true
-respectively.  They are singletons for the data type.
-The equivalent C constants are: Qnil, Qfalse, Qtrue.
-Note that Qfalse is false in C also (i.e. 0), but not Qnil.
-
-The T_FIXNUM data is a 31bit or 63bit length fixed integer.
-This size is depend on the size of long: if long is 32bit then
-T_FIXNUM is 31bit, if long is 64bit then T_FIXNUM is 63bit.
-T_FIXNUM can be converted to a C integer by using the
-FIX2INT() macro or FIX2LONG().  Though you have to check that the
-data is really FIXNUM before using them, they are faster.  FIX2LONG()
-never raises exceptions, but FIX2INT() raises RangeError if the
-result is bigger or smaller than the size of int.
-There are also NUM2INT() and NUM2LONG() which converts any Ruby
-numbers into C integers.  These macros includes a type check,
-so an exception will be raised if the conversion failed.  NUM2DBL()
-can be used to retrieve the double float value in the same way.
-
-You can use the macros
-StringValue() and StringValuePtr() to get a char* from a VALUE.
-StringValue(var) replaces var's value with the result of "var.to_str()".
-StringValuePtr(var) does same replacement and returns char*
-representation of var.  These macros will skip the replacement if var
-is a String.  Notice that the macros take only the lvalue as their
-argument, to change the value of var in place.
-
-You can also use the macro named StringValueCStr(). This is just
-like StringValuePtr(), but always add nul character at the end of
-the result. If the result contains nul character, this macro causes
-the ArgumentError exception.
-StringValuePtr() doesn't guarantee the existence of a nul at the end
-of the result, and the result may contain nul.
-
-Other data types have corresponding C structures, e.g. struct RArray
-for T_ARRAY etc. 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".
-
-There are some accessing macros for structure members, for example
-`RSTRING_LEN(str)' to get the size of the Ruby String object.  The
-allocated region can be accessed by `RSTRING_PTR(str)'.  For arrays,
-use `RARRAY_LEN(ary)' and `RARRAY_PTR(ary)' 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)
-  rb_str_new_cstr(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)
-  rb_tainted_str_new_cstr(const char *ptr)
-
-    Creates a new tainted Ruby string from a C string.
-
-  rb_sprintf(const char *format, ...)
-  rb_vsprintf(const char *format, va_list ap)
-
-    Creates a new Ruby string with printf(3) format.
-
-  rb_str_cat(VALUE str, const char *ptr, long len)
-
-    Appends len bytes of data from ptr to the Ruby string.
-
-  rb_str_cat2(VALUE str, const char* ptr)
-
-    Appends C string ptr to Ruby string str.  This function is
-    equivalent to rb_str_cat(str, ptr, strlen(ptr)).
-
-  rb_str_catf(VALUE str, const char* format, ...)
-  rb_str_vcatf(VALUE str, const char* format, va_list ap)
-
-    Appends C string format and successive arguments to Ruby string
-    str according to a printf-like format.  These functions are
-    equivalent to rb_str_cat2(str, rb_sprintf(format, ...)) and
-    rb_str_cat2(str, rb_vsprintf(format, ap)), respectively.
-
-  rb_enc_str_new(const char *ptr, long len, rb_encoding *enc)
-  
-    Creates a new Ruby string with the specified encoding.
-     
-  rb_usascii_str_new(const char *ptr, long len)
-  rb_usascii_str_new_cstr(const char *ptr)
-
-    Creates a new Ruby string with encoding US-ASCII.
-
-  rb_str_resize(VALUE str, long len)
-
-    Resizes Ruby string to len bytes.  If str is not modifiable, this
-    function raises an exception.  The length of str must be set in
-    advance.  If len is less than the old length the content beyond
-    len bytes is discarded, else if len is greater than the old length
-    the content beyond the old length bytes will not be preserved but
-    will be garbage.  Note that RSTRING_PTR(str) may change by calling
-    this function.
-
-  rb_str_set_len(VALUE str, long len)
-
-    Sets the length of Ruby string.  If str is not modifiable, this
-    function raises an exception.  This function preserves the content
-    upto len bytes, regardless RSTRING_LEN(str).  len must not exceed
-    the capacity of str.
-
- 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_to_ary(VALUE obj)
-
-    Converts the object into an array.
-    Equivalent to Object#to_ary.
-
- There are many functions to operate an array.
- They may dump core if other types are given.
-
-  rb_ary_aref(argc, VALUE *argv, VALUE ary)
-
-    Equivaelent to Array#[].
-
-  rb_ary_entry(VALUE ary, long offset)
-
-    ary[offset]
-
-  rb_ary_subseq(VALUE ary, long beg, long len)
-
-    ary[beg, len]
-
-  rb_ary_push(VALUE ary, VALUE val)
-  rb_ary_pop(VALUE ary)
-  rb_ary_shift(VALUE ary)
-  rb_ary_unshift(VALUE ary, VALUE val)
-
-
-2. Extending Ruby with C
-
-2.1 Adding 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 some more functions to define methods. One takes an ID
-as the name of method to be defined. See 2.2.2 for IDs.
-
-  void rb_define_method_id(VALUE klass, ID name, 
-                           VALUE (*func)(ANYARGS), int argc)
-
-There are two functions to define private/protected methods:
-
-  void rb_define_private_method(VALUE klass, const char *name, 
-			        VALUE (*func)(), int argc)
-  void rb_define_protected_method(VALUE klass, const char *name, 
-			          VALUE (*func)(), int argc)
-
-At last, rb_define_module_function defines a 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)
-
-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 a reader/writer for an attribute,
-
-  void rb_define_attr(VALUE klass, const char *name, int read, int write)
-
-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 has to take the klass as the argument and return a newly
-allocated instance.  This instance should be as 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.
-
-Note that the evaluation can raise an exception. There is a safer 
-function:
-
-  VALUE rb_eval_string_protect(const char *str, int *state)
-
-It returns nil when an error occur. Moreover, *state is zero if str was
-successfully evaluated, or nonzero otherwise.
-
-
-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
-or
- :"any kind of string"
-
-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
-
-As stated in section 1.3,
-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(const char *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().
-
-The prototypes of the getter and setter functions are as follows:
-
-  VALUE (*getter)(ID id, VALUE *var);
-  void (*setter)(VALUE val, ID id, VALUE *var);
-
-
-Also you can define a Ruby global variable without a corresponding C
-variable.  The value of the variable will be set/get only by hooks.
-
-  void rb_define_virtual_variable(const char *name,
-				  VALUE (*getter)(), void (*setter)())
-
-The prototypes of the getter and setter functions are as follows:
-
-  VALUE (*getter)(ID id);
-  void (*setter)(VALUE val, ID id);
-
-
-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.
-
-These mark / free functions are invoked during GC execution.  No
-object allocations are allowed during it, so do not allocate ruby
-objects inside them.
-
-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.
-Note that some functions in mkmf library described below generate
-a file ``conftest.c'' for checking with compilation.  You shouldn't
-choose ``conftest.c'' as a name of a source file.
-
-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.
-
---
-void
-Init_dbm(void)
-{
-    /* 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(VALUE obj, VALUE 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(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.  The third argument is a string that specifies how to
-capture method arguments and assign them to the following VALUE
-references.
-
-
-The following is an example of a method that takes arguments by Ruby's
-array:
-
---
-static VALUE
-thread_initialize(VALUE thread, VALUE 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
-
-TYPE(value)
-FIXNUM_P(value)
-NIL_P(value)
-void Check_Type(VALUE value, int type)
-void Check_SafeStr(VALUE value)
-
-** Data type conversion
-
-FIX2INT(value), INT2FIX(i)
-FIX2LONG(value), LONG2FIX(l)
-NUM2INT(value), INT2NUM(i)
-NUM2UINT(value), UINT2NUM(ui)

-
-** defining class/module
-
- VALUE rb_define_class(const char *name, VALUE super)
-
-Defines a new Ruby class as a subclass of super.
-
- VALUE rb_define_class_under(VALUE module, const char *name, VALUE super)
-
-Creates a new Ruby class as a subclass of super, under the module's
-namespace.
-
- VALUE rb_define_module(const char *name)
-
-Defines a new Ruby module.
-
- VALUE rb_define_module_under(VALUE module, const char *name)
-
-Defines a new Ruby module under the module's namespace.
-
- void rb_include_module(VALUE klass, VALUE module)
-
-Includes module into class.  If class already includes it, just
-ignored.
-
- void rb_extend_object(VALUE object, VALUE module)
-
-Extend the object with the module's attributes.
-
-** Defining Global Variables
-
- void rb_define_variable(const char *name, VALUE *var)
-
-Defines a global variable which is shared between C and Ruby.  If name
-contains a character which is not allowed to be part of the symbol,
-it can't be seen from Ruby programs.
-
- void rb_define_readonly_variable(const char *name, VALUE *var)
-
-Defines a read-only global variable.  Works just like
-rb_define_variable(), except the defined variable is read-only.
-
- 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
-
-	void setter(VALUE val, ID id, VALUE *var)
-
-GC requires C global variables which hold Ruby values to be marked.
-
- void rb_global_variable(VALUE *var)
-
-Tells GC to protect these variables.
-
-** Constant Definition
-
- void rb_define_const(VALUE klass, const char *name, VALUE val)
-
-Defines a new constant under the class/module.
-
- void rb_define_global_const(const char *name, VALUE val)
-
-Defines a global constant.  This is just the same as
-
-     rb_define_const(cKernal, name, val)
-
-** 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
-3 arguments: argc, argv, and self.  if argc is -2, the function will
-receive 2 arguments, self and args, where args is a Ruby array of
-the method arguments.
-
- rb_define_private_method(VALUE klass, const char *name, VALUE (*func)(), int argc)
-
-Defines a private method for the class.  Arguments are same as
-rb_define_method().
-
- rb_define_singleton_method(VALUE klass, const char *name, VALUE (*func)(), int argc)
-
-Defines a singleton method.  Arguments are same as rb_define_method().
-
- rb_scan_args(int argc, VALUE *argv, const char *fmt, ...)
-
-Retrieve argument from argc and argv to given VALUE references
-according to the format string.  The format can be described in ABNF
-as follows:
-
---
-scan-arg-spec  := param-arg-spec [option-hash-arg-spec] [block-arg-spec]
-
-param-arg-spec := pre-arg-spec [post-arg-spec] / post-arg-spec / pre-opt-post-arg-spec
-pre-arg-spec   := num-of-leading-mandatory-args [num-of-optional-args]

-option-hash-arg-spec := sym-for-option-hash-arg
-block-arg-spec := sym-for-block-arg
-
-num-of-leading-mandatory-args  := DIGIT ; The number of leading
-                                        ; mandatory arguments
-num-of-optional-args           := DIGIT ; The number of optional
-                                        ; arguments
-sym-for-variable-length-args   := "*"   ; Indicates that variable
-                                        ; length arguments are
-                                        ; captured as a ruby array
-num-of-trailing-mandatory-args := DIGIT ; The number of trailing

-sym-for-option-hash-arg        := ":"   ; Indicates that an option
-                                        ; hash is captured if the last
-                                        ; argument is a hash or can be

-                                        ; #to_hash.  When the last
-                                        ; argument is nil, it is
-                                        ; captured if it is not
-                                        ; ambiguous to take it as

---
-
-For example, "12" means that the method requires at least one
-argument, and at most receives three (1+2) arguments.  So, the format
-string must be followed by three variable references, which are to be
-assigned to captured arguments.  For omitted arguments, variables are
-set to Qnil.  NULL can be put in place of a variable reference, which
-means the corresponding captured argument(s) should be just dropped.
-
-The number of given arguments, excluding an option hash or iterator
-block, is returned.
-
-** 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().
-
- VALUE rb_funcall2(VALUE recv, ID mid, int argc, VALUE *argv)
-
-Invokes a method, passing arguments by an array of values.
-
- VALUE rb_eval_string(const char *str)
-
-Compiles and executes the string as a Ruby program.
-
- ID rb_intern(const char *name)
-
-Returns ID corresponding to the name.
-
- char *rb_id2name(ID id)
-
-Returns the name corresponding ID.
-
- 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)
-
-Retrieve the value of the instance variable.  If the name is not
-prefixed by `@', that variable shall be inaccessible from Ruby.
-
- VALUE rb_iv_set(VALUE obj, const char *name, VALUE val)
-
-Sets the value of the instance variable.
-
-** Control Structure
-
- VALUE rb_block_call(VALUE recv, ID mid, int argc, VALUE * argv,
-		     VALUE (*func) (ANYARGS), VALUE data2)
-
-Calls a method on the recv, with the method name specified by the
-symbol mid, with argc arguments in argv, supplying func as the
-block. When func is called as the block, it will receive the value
-from yield as the first argument, and data2 as the second argument.
-When yielded with multiple values (in C, rb_yield_values(),
-rb_yield_values2() and rb_yield_splat()), data2 is packed as an Array,
-whereas yielded values can be gotten via argc/argv of the third/fourth
-arguments.
-
- [OBSOLETE] 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.
- 
-When rb_iterate is used in 1.9, func1 has to call some Ruby-level method.
-This function is obsolete since 1.9; use rb_block_call instead.
-
- VALUE rb_yield(VALUE val)
-
-Evaluates the block with value val.
-
- VALUE rb_rescue(VALUE (*func1)(), VALUE arg1, VALUE (*func2)(), VALUE 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)(), VALUE arg1, VALUE (*func2)(), VALUE arg2)
-
-Calls the function func1 with arg1 as the argument, then calls func2
-with arg2 if execution terminated.  The return value from
-rb_ensure() is that of func1 when no exception occured.
-
- VALUE rb_protect(VALUE (*func) (VALUE), VALUE arg, int *state)
-
-Calls the function func with arg as the argument.  If no exception
-occured during func, it returns the result of func and *state is zero.
-Otherwise, it returns Qnil and sets *state to nonzero.  If state is
-NULL, it is not set in both cases.
-
- void rb_jump_tag(int state)
-
-Continues the exception caught by rb_protect() and rb_eval_string_protect().
-state must be the returned value from those functions.  This function
-never return to the caller.
-
-** Exceptions and Errors
-
- void rb_warn(const char *fmt, ...)
-
-Prints a warning message according to a printf-like format.
-
- void rb_warning(const char *fmt, ...)
-
-Prints a warning message according to a printf-like format, if
-$VERBOSE is true.
-
-void rb_raise(rb_eRuntimeError, const char *fmt, ...)
-
-Raises RuntimeError.  The fmt is a format string just like printf().
-
- void rb_raise(VALUE exception, const char *fmt, ...)
-
-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.
-
-** Initialize and Start the Interpreter

-The embedding API functions are below (not needed for extension libraries):
-
- void ruby_init()
-
-Initializes the interpreter.
-
- void ruby_options(int argc, char **argv)
-
-Process command line arguments for the interpreter.
-
- void ruby_run()
-
-Starts execution of the interpreter.
-
- void ruby_script(char *name)
-
-Specifies the name of the script ($0).
-
-** Hooks for the Interpreter Events
-
- void rb_add_event_hook(rb_event_hook_func_t func, rb_event_flag_t events, VALUE data)
-
-Adds a hook function for the specified interpreter events.
-events should be Or'ed value of:
-
-	RUBY_EVENT_LINE

-	RUBY_EVENT_CALL
-	RUBY_EVENT_RETURN
-	RUBY_EVENT_C_CALL
-	RUBY_EVENT_C_RETURN
-	RUBY_EVENT_RAISE
-	RUBY_EVENT_ALL
-

-
- typedef void (*rb_event_hook_func_t)(rb_event_t event, VALUE data,
- 				      VALUE self, ID id, VALUE klass)
-
-The third argument `data' to rb_add_event_hook() is passed to the hook
-function as the second argument, which was the pointer to the current
-NODE in 1.8.  See RB_EVENT_HOOKS_HAVE_CALLBACK_DATA below.
-
- int rb_remove_event_hook(rb_event_hook_func_t func)
-
-Removes the specified hook function.
-
-** Macros for the Compatibilities

-instance, when HAVE_RUBY_ST_H is defined you should use ruby/st.h not
-mere st.h.
-
- RB_EVENT_HOOKS_HAVE_CALLBACK_DATA
-
-Means that rb_add_event_hook() takes the third argument `data', to be
-passed to the given event hook function.

+
+# 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://docs.ruby-lang.org/en/master/maintainers_md.html#label-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．
+
+### Git
+
+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．
+
+```console
+$ git clone https://github.com/ruby/ruby.git
+```
+
+他のブランチの一覧は次のコマンドで見られます．
+
+```console
+$ git ls-remote https://github.com/ruby/ruby.git
+```
+
+Rubyリポジトリの本来のmasterは https://git.ruby-lang.org/ruby.git にあります．
+コミッタはこちらを使います．
+
+## 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 [ruby-list-request@ml.ruby-lang.org] まで件名に
+
+    join
+
+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 [ruby-dev-request@ml.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．
+
+[ruby-list-request@ml.ruby-lang.org]: mailto:ruby-list-request@ml.ruby-lang.org?subject=join
+[ruby-dev-request@ml.ruby-lang.org]: mailto:ruby-dev-request@ml.ruby-lang.org?subject=join
+
+## 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.  (Gitリポジトリから取得したソースをビルドする場合) `./autogen.sh` 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)`include/ruby/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．
