+
+      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.

+# 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
+
+## Core classes updates
+
+Note: We're only listing outstanding class updates.
+
+* Method
+
+    * `Method#source_location`, `Proc#source_location`, and
+      `UnboundMethod#source_location` now return extended location
+      information with 5 elements: `[path, start_line, start_column,
+      end_line, end_column]`. The previous 2-element format `[path,
+      line]` can still be obtained by calling `.take(2)` on the result.
+      [[Feature #6012]]
+
+* Set
+
+    * A deprecated behavior, `Set#to_set`, `Range#to_set`, and
+      `Enumerable#to_set` accepting arguments, was removed.  [[Feature #21390]]
+
+## Stdlib updates
+
+### The following bundled gems are added.

-# What's Ruby
+[日本語](rdoc-ref:README.ja.md)
 
-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.
+# What is Ruby?
 
-## Features of Ruby
+Ruby is an interpreted object-oriented programming language often
+used for web development. It also offers many scripting features
+to process plain text and serialized files, or manage system tasks.
+It is simple, straightforward, and extensible.
 
-*   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, Mac OS X, BeOS, etc.) cf.

-## 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 instead of this document.
-
-2.  If `./configure` does not exist or is older than configure.in, 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.
+    join
 
-    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`.
+in the mail subject (not body) to the address [ruby-talk-request@ml.ruby-lang.org].
 
-    Usually this step will not be needed.
-
-6.  Run `make`.
-
-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.  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.
-
-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.

 /*
- *  Arrays are ordered, integer-indexed collections of any object.
+ *  An \Array object is an ordered, integer-indexed collection of objects,
+ *  called _elements_;
+ *  the object represents
+ *  an {array data structure}[https://en.wikipedia.org/wiki/Array_(data_structure)].
+ *
+ *  An element may be any object (even another array);
+ *  elements may be any mixture of objects of different types.
  *
- *  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.
+ *  Important data structures that use arrays include:
+ *
+ *  - {Coordinate vector}[https://en.wikipedia.org/wiki/Coordinate_vector].
+ *  - {Matrix}[https://en.wikipedia.org/wiki/Matrix_(mathematics)].
+ *  - {Heap}[https://en.wikipedia.org/wiki/Heap_(data_structure)].
+ *  - {Hash table}[https://en.wikipedia.org/wiki/Hash_table].
+ *  - {Deque (double-ended queue)}[https://en.wikipedia.org/wiki/Double-ended_queue].
+ *  - {Queue}[https://en.wikipedia.org/wiki/Queue_(abstract_data_type)].
+ *  - {Stack}[https://en.wikipedia.org/wiki/Stack_(abstract_data_type)].
+ *
+ *  There are also array-like data structures:
+ *
+ *  - {Associative array}[https://en.wikipedia.org/wiki/Associative_array] (see Hash).
+ *  - {Directory}[https://en.wikipedia.org/wiki/Directory_(computing)] (see Dir).
+ *  - {Environment}[https://en.wikipedia.org/wiki/Environment_variable] (see ENV).
+ *  - {Set}[https://en.wikipedia.org/wiki/Set_(abstract_data_type)] (see Set).
+ *  - {String}[https://en.wikipedia.org/wiki/String_(computer_science)] (see String).
+ *
+ *  == \Array Indexes
+ *
+ *  \Array indexing starts at 0, as in C or Java.
+ *
+ *  A non-negative index is an offset from the first element:
+ *
+ *  - Index 0 indicates the first element.
+ *  - Index 1 indicates the second element.
+ *  - ...
+ *
+ *  A negative index is an offset, backwards, from the end of the array:
+ *
+ *  - Index -1 indicates the last element.
+ *  - Index -2 indicates the next-to-last element.
+ *  - ...
+ *
+ *
+ *  === In-Range and Out-of-Range Indexes
+ *
+ *  A non-negative index is <i>in range</i> if and only if it is smaller than
+ *  the size of the array.  For a 3-element array:
+ *
+ *  - Indexes 0 through 2 are in range.
+ *  - Index 3 is out of range.
+ *
+ *  A negative index is <i>in range</i> if and only if its absolute value is
+ *  not larger than the size of the array.  For a 3-element array:
+ *
+ *  - Indexes -1 through -3 are in range.
+ *  - Index -4 is out of range.
+ *
+ *  === Effective Index
+ *
+ *  Although the effective index into an array is always an integer,
+ *  some methods (both within class \Array and elsewhere)
+ *  accept one or more non-integer arguments that are
+ *  {integer-convertible objects}[rdoc-ref:implicit_conversion.rdoc@Integer-Convertible+Objects].
  *
  *  == 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:
+ *  You can create an \Array object explicitly with:
+ *
+ *  - An {array literal}[rdoc-ref:syntax/literals.rdoc@Array+Literals]:
+ *
+ *      [1, 'one', :one, [2, 'two', :two]]
+ *
+ *  - A {%w or %W string-array Literal}[rdoc-ref:syntax/literals.rdoc@25w+and+-25W-3A+String-Array+Literals]:
+ *
+ *      %w[foo bar baz] # => ["foo", "bar", "baz"]
+ *      %w[1 % *]       # => ["1", "%", "*"]
  *
- *     ary = [1, "two", 3.0] #=> [1, "two", 3.0]
+ *  - A {%i or %I symbol-array Literal}[rdoc-ref:syntax/literals.rdoc@25i+and+-25I-3A+Symbol-Array+Literals]:
  *
- *  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).
+ *      %i[foo bar baz] # => [:foo, :bar, :baz]
+ *      %i[1 % *]       # => [:"1", :%, :*]
  *
- *     ary = Array.new    #=> []
- *     Array.new(3)       #=> [nil, nil, nil]
- *     Array.new(3, true) #=> [true, true, true]
+ *  - Method Kernel#Array:
  *
- *  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.
+ *      Array(["a", "b"])             # => ["a", "b"]
+ *      Array(1..5)                   # => [1, 2, 3, 4, 5]
+ *      Array(key: :value)            # => [[:key, :value]]
+ *      Array(nil)                    # => []
+ *      Array(1)                      # => [1]
+ *      Array({:a => "a", :b => "b"}) # => [[:a, "a"], [:b, "b"]]
  *
- *  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:
+ *  - Method Array.new:
  *
- *     Array.new(4) { Hash.new } #=> [{}, {}, {}, {}]
+ *      Array.new               # => []
+ *      Array.new(3)            # => [nil, nil, nil]
+ *      Array.new(4) {Hash.new} # => [{}, {}, {}, {}]
+ *      Array.new(3, true)      # => [true, true, true]
  *
- *  This is also a quick way to build up multi-dimensional arrays:
+ *    Note that the last example above populates the array
+ *    with references to the same object.
+ *    This is recommended only in cases where that object is a natively immutable object
+ *    such as a symbol, a numeric, +nil+, +true+, or +false+.
  *
- *     empty_table = Array.new(3) { Array.new(3) }
- *     #=> [[nil, nil, nil], [nil, nil, nil], [nil, nil, nil]]
+ *    Another way to create an array with various objects, using a block;
+ *    this usage is safe for mutable objects such as hashes, strings or
+ *    other arrays:
  *
- *  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.new(4) {|i| i.to_s } # => ["0", "1", "2", "3"]
  *
- *	Array({:a => "a", :b => "b"}) #=> [[:a, "a"], [:b, "b"]]
+ *    Here is a way to create a multi-dimensional array:
+ *
+ *      Array.new(3) {Array.new(3)}
+ *      # => [[nil, nil, nil], [nil, nil, nil], [nil, nil, nil]]
+ *
+ *  A number of Ruby methods, both in the core and in the standard library,
+ *  provide instance method +to_a+, which converts an object to an array.
+ *
+ *  - ARGF#to_a

+# AbstractSyntaxTree provides methods to parse Ruby code into
+# abstract syntax trees. The nodes in the tree
+# are instances of RubyVM::AbstractSyntaxTree::Node.
+#
+# This module is MRI specific as it exposes implementation details
+# of the MRI abstract syntax tree.
+#
+# This module is experimental and its API is not stable, therefore it might
+# change without notice. As examples, the order of children nodes is not
+# guaranteed, the number of children nodes might change, there is no way to
+# access children nodes by name, etc.
+#
+# If you are looking for a stable API or an API working under multiple Ruby
+# implementations, consider using the _prism_ gem, which is the official
+# Ruby API to parse Ruby code.

+  #  Parses the given _string_ into an abstract syntax tree,

+## 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 vm benchmarks
+make benchmark ITEM=vm
+
+# Run some limited benchmarks in ITEM-matched files
+make benchmark ITEM=vm 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=vm_bigarray OPTS="-r peak"
+```

-# determines if a board is punable, meaning that there is no possibility that it
-# can be filled up with pieces.  A board is prunable if there is a grouping of unfilled spaces
-# that are not a multiple of five.  The following board is an example of a prunable board:
-#    0 0 1 0 0
-#     0 1 0 0 0
-#    1 1 0 0 0
-#     0 1 0 0 0
-#    0 0 0 0 0
-#       ...
-#
-# This board is prunable because the top left corner is only 3 bits in area, no piece will ever fit it
-# parameters:
-#   board -- an initial bit board (6 bit padded rows, see blank_board for format)
-#   location -- starting location, everything above and to the left is already full
-#   slotting -- set to true only when testing initial pieces, when filling normally
-#               additional assumptions are possible
-#
-# Algorithm:
-#    The algorithm starts at the top row (as determined by location) and iterates a row at a time
-#    maintainng counts of active open areas (kept in the collector array) each collector contains
-#    three values at the start of an iteration:
-#          0: mask of bits that would be adjacent to the collector in this row
-#          1: the number of bits collected so far
-#          2: a scratch space starting as zero, but used during the computation to represent

-#   in the cycle.  We still need to keep checking all the permutations, but our probability of finding one will
-#   diminsh over time.  Since we are TOLD how many to search for this lets us exit before checking all pieces

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

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

- * \defgroup defmethod Defining methods
- * There are some APIs to define a method from C.
- * These API takes a C function as a method body.
- *
- * \par Method body functions
- * Method body functions must return a VALUE and
- * can be one of the following form:
- * <dl>
- * <dt>Fixed number of parameters</dt>
- * <dd>
- *     This form is a normal C function, excepting it takes
- *     a receiver object as the first argument.
- *

- *     \endcode
- * </dd>
- * <dt>argc and argv style</dt>
- * <dd>
- *     This form takes three parameters: \a argc, \a argv and \a self.
- *     \a self is the receiver. \a argc is the number of arguments.
- *     \a argv is a pointer to an array of the arguments.
- *
- *     \code
- *     static VALUE my_method(int argc, VALUE *argv, VALUE self);
- *     \endcode
- * </dd>
- * <dt>Ruby array style</dt>
- * <dd>
- *     This form takes two parameters: self and args.
- *     \a self is the receiver. \a args is an Array object which
- *     contains the arguments.

- * </dd>
- *
- * \par Number of parameters
- * Method defining APIs takes the number of parameters which the
- * method will takes. This number is called \a argc.
- * \a argc can be:
- * <dl>
- * <dt>zero or positive number</dt>
- * <dd>This means the method body function takes a fixed number of parameters</dd>
- * <dt>-1</dt>
- * <dd>This means the method body function is "argc and argv" style.</dd>

+/* Multiple Assignment Handling
+ *
+ * In order to handle evaluation of multiple assignment such that the left hand side
+ * is evaluated before the right hand side, we need to process the left hand side
+ * and see if there are any attributes that need to be assigned, or constants set
+ * on explicit objects.  If so, we add instructions to evaluate the receiver of
+ * any assigned attributes or constants before we process the right hand side.
+ *
+ * For a multiple assignment such as:
+ *
+ *   l1.m1, l2[0] = r3, r4
+ *
+ * We start off evaluating l1 and l2, then we evaluate r3 and r4, then we
+ * assign the result of r3 to l1.m1, and then the result of r4 to l2.m2.
+ * On the VM stack, this looks like:
+ *
+ *     self                               # putself
+ *     l1                                 # send
+ *     l1, self                           # putself
+ *     l1, l2                             # send
+ *     l1, l2, 0                          # putobject 0
+ *     l1, l2, 0, [r3, r4]                # after evaluation of RHS
+ *     l1, l2, 0, [r3, r4], r4, r3        # expandarray
+ *     l1, l2, 0, [r3, r4], r4, r3, l1    # topn 5
+ *     l1, l2, 0, [r3, r4], r4, l1, r3    # swap
+ *     l1, l2, 0, [r3, r4], r4, m1=       # send
+ *     l1, l2, 0, [r3, r4], r4            # pop
+ *     l1, l2, 0, [r3, r4], r4, l2        # topn 3
+ *     l1, l2, 0, [r3, r4], r4, l2, 0     # topn 3
+ *     l1, l2, 0, [r3, r4], r4, l2, 0, r4 # topn 2
+ *     l1, l2, 0, [r3, r4], r4, []=       # send
+ *     l1, l2, 0, [r3, r4], r4            # pop
+ *     l1, l2, 0, [r3, r4]                # pop
+ *     [r3, r4], l2, 0, [r3, r4]          # setn 3
+ *     [r3, r4], l2, 0                    # pop
+ *     [r3, r4], l2                       # pop
+ *     [r3, r4]                           # pop
+ *
+ * This is made more complex when you have to handle splats, post args,
+ * and arbitrary levels of nesting.  You need to keep track of the total
+ * number of attributes to set, and for each attribute, how many entries
+ * are on the stack before the final attribute, in order to correctly
+ * calculate the topn value to use to get the receiver of the attribute
+ * setter method.
+ *
+ * A brief description of the VM stack for simple multiple assignment
+ * with no splat (rhs_array will not be present if the return value of
+ * the multiple assignment is not needed):
+ *
+ *     lhs_attr1, lhs_attr2, ..., rhs_array, ..., rhs_arg2, rhs_arg1
+ *
+ * For multiple assignment with splats, while processing the part before
+ * the splat (splat+post here is an array of the splat and the post arguments):
+ *
+ *     lhs_attr1, lhs_attr2, ..., rhs_array, splat+post, ..., rhs_arg2, rhs_arg1
+ *
+ * When processing the splat and post arguments:
+ *
+ *     lhs_attr1, lhs_attr2, ..., rhs_array, ..., post_arg2, post_arg1, splat
+ *
+ * When processing nested multiple assignment, existing values on the stack
+ * are kept.  So for:
+ *
+ *     (l1.m1, l2.m2), l3.m3, l4* = [r1, r2], r3, r4
+ *
+ * The stack layout would be the following before processing the nested
+ * multiple assignment:
+ *
+ *     l1, l2, [[r1, r2], r3, r4], [r4], r3, [r1, r2]
+ *
+ * In order to handle this correctly, we need to keep track of the nesting
+ * level for each attribute assignment, as well as the attribute number
+ * (left hand side attributes are processed left to right) and number of
+ * arguments to pass to the setter method. struct masgn_lhs_node tracks
+ * this information.
+ *
+ * We also need to track information for the entire multiple assignment, such
+ * as the total number of arguments, and the current nesting level, to
+ * handle both nested multiple assignment as well as cases where the
+ * rhs is not needed.  We also need to keep track of all attribute
+ * assignments in this, which we do using a linked listed. struct masgn_state
+ * tracks this information.

+ * <b>In Brief</b>
+ *

+ *
+ * <b>Parsed Values</b>
+ *
+ * The parsing may be thought of as searching for numeric literals
+ * embedded in the substring.
+ *
+ * This section shows how the method parses numeric values from leading substrings.
+ * The examples show real-only or imaginary-only parsing;
+ * the parsing is the same for each part.
+ *
+ *   '1foo'.to_c # => (1+0i)      # Ignores trailing unparsed characters.
+ *   ' 1 '.to_c  # => (1+0i)      # Ignores leading and trailing whitespace.
+ *   'x1'.to_c   # => (0+0i)      # Finds no leading numeric.
+ *
+ *   # Integer literal embedded in the substring.
+ *   '1'.to_c       # => (1+0i)
+ *   '-1'.to_c      # => (-1+0i)
+ *   '1i'.to_c      # => (0+1i)
+ *
+ *   # Integer literals that don't work.
+ *   '0b100'.to_c   # => (0+0i)   # Not parsed as binary.
+ *   '0o100'.to_c   # => (0+0i)   # Not parsed as octal.
+ *   '0d100'.to_c   # => (0+0i)   # Not parsed as decimal.
+ *   '0x100'.to_c   # => (0+0i)   # Not parsed as hexadecimal.
+ *   '010'.to_c     # => (10+0i)  # Not parsed as octal.
+ *
+ *   # Float literals:
+ *   '3.14'.to_c    # => (3.14+0i)
+ *   '3.14i'.to_c   # => (0+3.14i)
+ *   '1.23e4'.to_c  # => (12300.0+0i)
+ *   '1.23e+4'.to_c # => (12300.0+0i)
+ *   '1.23e-4'.to_c # => (0.000123+0i)
+ *
+ *   # Rational literals:
+ *   '1/2'.to_c     # => ((1/2)+0i)
+ *   '-1/2'.to_c    # => ((-1/2)+0i)
+ *   '1/2r'.to_c    # => ((1/2)+0i)
+ *   '-1/2r'.to_c   # => ((-1/2)+0i)
+ *
+ * <b>Rectangular Coordinates</b>
+ *
+ * With separator <tt>'+'</tt> or <tt>'-'</tt>,
+ * or with no separator,
+ * interprets the values as rectangular coordinates: real and imaginary.
+ *
+ * With no separator, assigns a single value to either the real or the imaginary part:
+ *
+ *   ''.to_c  # => (0+0i)  # Defaults to zero.
+ *  '1'.to_c  # => (1+0i)  # Real (no trailing 'i').
+ *  '1i'.to_c # => (0+1i)  # Imaginary (trailing 'i').
+ *  'i'.to_c  # => (0+1i)  # Special case (imaginary 1).
+ *
+ * With separator <tt>'+'</tt>, both parts positive (or zero):
+ *
+ *   # Without trailing 'i'.
+ *   '+'.to_c    # => (0+0i)  # No values: defaults to zero.
+ *   '+1'.to_c   # => (1+0i)  # Value after '+': real only.
+ *   '1+'.to_c   # => (1+0i)  # Value before '+': real only.
+ *   '2+1'.to_c  # => (2+0i)  # Values before and after '+': real and imaginary.

+ *   '2+i'.to_c  # => (2+1i)  # Value before '+': real and imaginary 1.
+ *   '2+1i'.to_c # => (2+1i)  # Values before and after '+': real and imaginary.
+ *
+ * With separator <tt>'-'</tt>, negative imaginary part:
+ *
+ *   # Without trailing 'i'.
+ *   '-'.to_c    # => (0+0i)   # No values: defaults to zero.
+ *   '-1'.to_c   # => (-1+0i)  # Value after '-': negative real, zero imaginary.
+ *   '1-'.to_c   # => (1+0i)   # Value before '-': positive real, zero imaginary.
+ *   '2-1'.to_c  # => (2+0i)   # Values before and after '-': positive real, zero imaginary.
+ *   # With trailing 'i'.
+ *   '-1i'.to_c  # => (0-1i)   # Value after '-': negative real, zero imaginary.
+ *   '2-i'.to_c  # => (2-1i)   # Value before '-': positive real, negative imaginary.
+ *   '2-1i'.to_c # => (2-1i)   # Values before and after '-': positive real, negative imaginary.
+ *
+ * Note that the suffixed character <tt>'i'</tt>
+ * may instead be one of <tt>'I'</tt>, <tt>'j'</tt>, or <tt>'J'</tt>,
+ * with the same effect.
+ *
+ * <b>Polar Coordinates</b>
+ *
+ * With separator <tt>'@'</tt>)
+ * interprets the values as polar coordinates: magnitude and angle.
+ *
+ *   '2@'.to_c.polar  # => [2, 0.0]    # Value before '@': magnitude only.
+ *    # Values before and after '@': magnitude and angle.
+ *   '2@1'.to_c.polar # => [2.0, 1.0]
+ *   "1.0@#{Math::PI/2}".to_c # => (0.0+1i)
+ *   "1.0@#{Math::PI}".to_c   # => (-1+0.0i)
+ *   # Magnitude not given: defaults to zero.
+ *   '@'.to_c.polar   # => [0, 0.0]
+ *   '@1'.to_c.polar  # => [0, 0.0]
+ *
+ *   '1.0@0'.to_c             # => (1+0.0i)
+ *
+ * Note that in all cases, the suffixed character <tt>'i'</tt>

 /*
- * A complex number can be represented as a paired real number with
- * imaginary unit; a+bi.  Where a is real part, b is imaginary part
- * and i is imaginary unit.  Real a equals complex a+0i
- * mathematically.
+ * A \Complex object houses a pair of values,
+ * given when the object is created as either <i>rectangular coordinates</i>
+ * or <i>polar coordinates</i>.
+ *
+ * == Rectangular Coordinates
+ *
+ * The rectangular coordinates of a complex number
+ * are called the _real_ and _imaginary_ parts;
+ * see {Complex number definition}[https://en.wikipedia.org/wiki/Complex_number#Definition_and_basic_operations].
+ *
+ * You can create a \Complex object from rectangular coordinates with:
+ *
+ * - A {complex literal}[rdoc-ref:syntax/literals.rdoc@Complex+Literals].
+ * - Method Complex.rect.
+ * - Method Kernel#Complex, either with numeric arguments or with certain string arguments.
+ * - Method String#to_c, for certain strings.
+ *
+ * Note that each of the stored parts may be a an instance one of the classes
+ * Complex, Float, Integer, or Rational;
+ * they may be retrieved:
+ *
+ * - Separately, with methods Complex#real and Complex#imaginary.
+ * - Together, with method Complex#rect.
+ *
+ * The corresponding (computed) polar values may be retrieved:
+ *
+ * - Separately, with methods Complex#abs and Complex#arg.
+ * - Together, with method Complex#polar.
  *
- * Complex object can be created as literal, and also by using
- * Kernel#Complex, Complex::rect, Complex::polar or to_c method.
+ * == Polar Coordinates
  *
- *    2+1i                 #=> (2+1i)
- *    Complex(1)           #=> (1+0i)
- *    Complex(2, 3)        #=> (2+3i)
- *    Complex.polar(2, 3)  #=> (-1.9799849932008908+0.2822400161197344i)
- *    3.to_c               #=> (3+0i)
+ * The polar coordinates of a complex number
+ * are called the _absolute_ and _argument_ parts;
+ * see {Complex polar plane}[https://en.wikipedia.org/wiki/Complex_number#Polar_form].
  *
- * You can also create complex object from floating-point numbers or
- * strings.
+ * In this class, the argument part
+ * in expressed {radians}[https://en.wikipedia.org/wiki/Radian]
+ * (not {degrees}[https://en.wikipedia.org/wiki/Degree_(angle)]).
  *
- *    Complex(0.3)         #=> (0.3+0i)

- *    Complex('1@2')       #=> (-0.4161468365471424+0.9092974268256817i)
+ * You can create a \Complex object from polar coordinates with:
  *
- *    0.3.to_c             #=> (0.3+0i)
- *    '0.3-0.5i'.to_c      #=> (0.3-0.5i)
- *    '2/3+3/4i'.to_c      #=> ((2/3)+(3/4)*i)
- *    '1@2'.to_c           #=> (-0.4161468365471424+0.9092974268256817i)
+ * - Method Complex.polar.
+ * - Method Kernel#Complex, with certain string arguments.
+ * - Method String#to_c, for certain strings.
  *
- * A complex object is either an exact or an inexact number.
+ * Note that each of the stored parts may be a an instance one of the classes
+ * Complex, Float, Integer, or Rational;
+ * they may be retrieved:
+ *
+ * - Separately, with methods Complex#abs and Complex#arg.
+ * - Together, with method Complex#polar.
+ *
+ * The corresponding (computed) rectangular values may be retrieved:
+ *
+ * - Separately, with methods Complex#real and Complex#imag.
+ * - Together, with method Complex#rect.
+ *
+ * == What's Here
+ *
+ * First, what's elsewhere:
+ *
+ * - Class \Complex inherits (directly or indirectly)
+ *   from classes {Numeric}[rdoc-ref:Numeric@What-27s+Here]
+ *   and {Object}[rdoc-ref:Object@What-27s+Here].
+ * - Includes (indirectly) module {Comparable}[rdoc-ref:Comparable@What-27s+Here].
+ *
+ * Here, class \Complex has methods for:
+ *
+ * === Creating \Complex Objects
+ *
+ * - ::polar: Returns a new \Complex object based on given polar coordinates.
+ * - ::rect (and its alias ::rectangular):
+ *   Returns a new \Complex object based on given rectangular coordinates.
+ *
+ * === Querying
+ *
+ * - #abs (and its alias #magnitude): Returns the absolute value for +self+.
+ * - #arg (and its aliases #angle and #phase):
+ *   Returns the argument (angle) for +self+ in radians.
+ * - #denominator: Returns the denominator of +self+.
+ * - #finite?: Returns whether both +self.real+ and +self.image+ are finite.
+ * - #hash: Returns the integer hash value for +self+.

+ * - #real?: Returns +false+; for compatibility with Numeric#real?.
+ * - #rect (and its alias #rectangular):
+ *   Returns the array <tt>[self.real, self.imag]</tt>.
+ *
+ * === Comparing
+ *
+ * - #<=>: Returns whether +self+ is less than, equal to, or greater than the given argument.
+ * - #==: Returns whether +self+ is equal to the given argument.
+ *
+ * === Converting
+ *
+ * - #rationalize: Returns a Rational object whose value is exactly
+ *   or approximately equivalent to that of <tt>self.real</tt>.
+ * - #to_c: Returns +self+.
+ * - #to_d: Returns the value as a BigDecimal object.
+ * - #to_f: Returns the value of <tt>self.real</tt> as a Float, if possible.
+ * - #to_i: Returns the value of <tt>self.real</tt> as an Integer, if possible.
+ * - #to_r: Returns the value of <tt>self.real</tt> as a Rational, if possible.
+ * - #to_s: Returns a string representation of +self+.
+ *
+ * === Performing Complex Arithmetic
+ *
+ * - #*: Returns the product of +self+ and the given numeric.
+ * - #**: Returns +self+ raised to power of the given numeric.
+ * - #+: Returns the sum of +self+ and the given numeric.
+ * - #-: Returns the difference of +self+ and the given numeric.
+ * - #-@: Returns the negation of +self+.
+ * - #/: Returns the quotient of +self+ and the given numeric.
+ * - #abs2: Returns square of the absolute value (magnitude) for +self+.
+ * - #conj (and its alias #conjugate): Returns the conjugate of +self+.
+ * - #fdiv: Returns <tt>Complex.rect(self.real/numeric, self.imag/numeric)</tt>.
+ *
+ * === Working with JSON
+ *
+ * - ::json_create: Returns a new \Complex object,
+ *   deserialized from the given serialized hash.
+ * - #as_json: Returns a serialized hash constructed from +self+.
+ * - #to_json: Returns a JSON string representing +self+.
+ *
+ * These methods are provided by the {JSON gem}[https://github.com/ruby/json]. To make these methods available:
+ *
+ *   require 'json/add/complex'
  *
- *    Complex(1, 1) / 2    #=> ((1/2)+(1/2)*i)
- *    Complex(1, 1) / 2.0  #=> (0.5+0.5i)

- *
- *  Note that this pattern is not a regexp, it's closer to a shell glob.  See

- *  <code>*</code>::
- *    Matches any file. Can be restricted by other values in the glob.
- *    Equivalent to <code>/ .* /x</code> in regexp.

- *
- *    Note, this will not match Unix-like hidden files (dotfiles).  In order

- *
- *  <code>**</code>::
- *    Matches directories recursively.
- *
- *  <code>?</code>::
- *    Matches any one character. Equivalent to <code>/.{1}/</code> in regexp.
- *
- *  <code>[set]</code>::
- *    Matches any one character in +set+.  Behaves exactly like character sets
- *    in Regexp, including set negation (<code>[^a-z]</code>).
- *
- *  <code>{p,q}</code>::
- *    Matches either literal <code>p</code> or literal <code>q</code>.
- *    Equivalent to pattern alternation in regexp.
- *

+# An object of class \Dir represents a directory in the underlying file system.
+#
+# It consists mainly of:
+#
+# - A string _path_, given when the object is created,
+#   that specifies a directory in the underlying file system;
+#   method #path returns the path.
+# - A collection of string <i>entry names</i>,
+#   each of which is the name of a directory or file in the underlying file system;
+#   the entry names may be retrieved
+#   in an {array-like fashion}[rdoc-ref:Dir@Dir+As+Array-Like]
+#   or in a {stream-like fashion}[rdoc-ref:Dir@Dir+As+Stream-Like].
+#
+# == About the Examples
+#
+# Some examples on this page use this simple file tree:
+#
+#   example/
+#   ├── config.h
+#   ├── lib/
+#   │   ├── song/
+#   │   │   └── karaoke.rb
+#   │   └── song.rb
+#   └── main.rb
+#
+# Others use the file tree for the
+# {Ruby project itself}[https://github.com/ruby/ruby].
+#
+# == \Dir As \Array-Like
+#
+# A \Dir object is in some ways array-like:
+#
+# - It has instance methods #children, #each, and #each_child.
+# - It includes {module Enumerable}[rdoc-ref:Enumerable@What-27s+Here].
+#
+# == \Dir As Stream-Like
+#
+# A \Dir object is in some ways stream-like.
+#
+# The stream is initially open for reading,
+# but may be closed manually (using method #close),
+# and will be closed on block exit if created by Dir.open called with a block.
+# The closed stream may not be further manipulated,
+# and may not be reopened.
+#
+# The stream has a _position_, which is the index of an entry in the directory:
+#
+# - The initial position is zero (before the first entry).
+# - Method #tell (aliased as #pos) returns the position.
+# - Method #pos= sets the position (but ignores a value outside the stream),
+#   and returns the position.
+# - Method #seek is like #pos=, but returns +self+ (convenient for chaining).
+# - Method #read, if not at end-of-stream, reads the next entry and increments
+#   the position;
+#   if at end-of-stream, does not increment the position.
+# - Method #rewind sets the position to zero.
+#
+# Examples (using the {simple file tree}[rdoc-ref:Dir@About+the+Examples]):
+#
+#   dir = Dir.new('example') # => #<Dir:example>
+#   dir.pos                  # => 0
+#
+#   dir.read # => "."
+#   dir.read # => ".."
+#   dir.read # => "config.h"
+#   dir.read # => "lib"
+#   dir.read # => "main.rb"
+#   dir.pos  # => 5
+#   dir.read # => nil
+#   dir.pos  # => 5
+#
+#   dir.rewind # => #<Dir:example>
+#   dir.pos    # => 0
+#
+#   dir.pos = 3 # => 3
+#   dir.pos     # => 3
+#
+#   dir.seek(4) # => #<Dir:example>
+#   dir.pos     # => 4
+#
+#   dir.close # => nil
+#   dir.read  # Raises IOError.
+#
+# == What's Here
+#
+# First, what's elsewhere. Class \Dir:
+#
+# - Inherits from {class Object}[rdoc-ref:Object@What-27s+Here].
+# - Includes {module Enumerable}[rdoc-ref:Enumerable@What-27s+Here],
+#   which provides dozens of additional methods.
+#
+# Here, class \Dir provides methods that are useful for:
+#
+# - {Reading}[rdoc-ref:Dir@Reading]
+# - {Setting}[rdoc-ref:Dir@Setting]
+# - {Querying}[rdoc-ref:Dir@Querying]
+# - {Iterating}[rdoc-ref:Dir@Iterating]
+# - {Other}[rdoc-ref:Dir@Other]
+#
+# === Reading
+#
+# - #close: Closes the directory stream for +self+.
+# - #pos=: Sets the position in the directory stream for +self+.
+# - #read: Reads and returns the next entry in the directory stream for +self+.
+# - #rewind: Sets the position in the directory stream for +self+ to the first entry.
+# - #seek: Sets the position in the directory stream for +self+
+#   the entry at the given offset.
+#
+# === Setting
+#
+# - ::chdir: Changes the working directory of the current process
+#   to the given directory.
+# - ::chroot: Changes the file-system root for the current process
+#   to the given directory.
+#
+# === Querying
+#
+# - ::[]: Same as ::glob without the ability to pass flags.
+# - ::children: Returns an array of names of the children
+#   (both files and directories) of the given directory,
+#   but not including <tt>.</tt> or <tt>..</tt>.
+# - ::empty?: Returns whether the given path is an empty directory.
+# - ::entries: Returns an array of names of the children
+#   (both files and directories) of the given directory,
+#   including <tt>.</tt> and <tt>..</tt>.
+# - ::exist?: Returns whether the given path is a directory.
+# - ::getwd (aliased as #pwd): Returns the path to the current working directory.
+# - ::glob: Returns an array of file paths matching the given pattern and flags.
+# - ::home: Returns the home directory path for a given user or the current user.
+# - #children: Returns an array of names of the children
+#   (both files and directories) of +self+,
+#   but not including <tt>.</tt> or <tt>..</tt>.
+# - #fileno: Returns the integer file descriptor for +self+.
+# - #path (aliased as #to_path): Returns the path used to create +self+.
+# - #tell (aliased as #pos): Returns the integer position
+#   in the directory stream for +self+.
+#
+# === Iterating
+#
+# - ::each_child: Calls the given block with each entry in the given directory,
+#   but not including <tt>.</tt> or <tt>..</tt>.
+# - ::foreach: Calls the given block with each entry in the given directory,
+#   including <tt>.</tt> and <tt>..</tt>.
+# - #each: Calls the given block with each entry in +self+,
+#   including <tt>.</tt> and <tt>..</tt>.
+# - #each_child: Calls the given block with each entry in +self+,
+#   but not including <tt>.</tt> or <tt>..</tt>.
+#
+# === Other
+#
+# - ::mkdir: Creates a directory at the given path, with optional permissions.
+# - ::new: Returns a new \Dir for the given path, with optional encoding.
+# - ::open: Same as ::new, but if a block is given, yields the \Dir to the block,
+#   closing it upon block exit.
+# - ::unlink (aliased as ::delete and ::rmdir): Removes the given directory.
+# - #inspect: Returns a string description of +self+.

+  # Each pattern string is expanded
+  # according to certain metacharacters;
+  # examples below use the {Ruby file tree}[rdoc-ref:Dir@About+the+Examples]:
+  #
+  # - <tt>'*'</tt>: Matches any substring in an entry name,
+  #   similar in meaning to regexp <tt>/.*/mx</tt>;
+  #   may be restricted by other values in the pattern strings:
+  #
+  #   - <tt>'*'</tt> matches all entry names:
+  #
+  #       Dir.glob('*').take(3)  # => ["BSDL", "CONTRIBUTING.md", "COPYING"]
+  #
+  #   - <tt>'c*'</tt> matches entry names beginning with <tt>'c'</tt>:
+  #
+  #       Dir.glob('c*').take(3) # => ["CONTRIBUTING.md", "COPYING", "COPYING.ja"]
+  #
+  #   - <tt>'*c'</tt> matches entry names ending with <tt>'c'</tt>:
+  #
+  #       Dir.glob('*c').take(3) # => ["addr2line.c", "array.c", "ast.c"]
+  #
+  #   - <tt>'\*c\*'</tt> matches entry names that contain <tt>'c'</tt>,
+  #     even at the beginning or end:
+  #
+  #       Dir.glob('*c*').take(3) # => ["CONTRIBUTING.md", "COPYING", "COPYING.ja"]
+  #
+  #   Does not match Unix-like hidden entry names ("dot files").
+  #   To include those in the matched entry names,
+  #   use flag IO::FNM_DOTMATCH or something like <tt>'{*,.*}'</tt>.
+  #
+  #  - <tt>'**'</tt>: Matches entry names recursively
+  #    if followed by  the slash character <tt>'/'</tt>:
+  #
+  #      Dir.glob('**/').take(3) # => ["basictest/", "benchmark/", "benchmark/gc/"]
+  #
+  #    If the string pattern contains other characters
+  #    or is not followed by a slash character,
+  #    it is equivalent to <tt>'*'</tt>.
+  #
+  # - <tt>'?'</tt> Matches any single character;
+  #   similar in meaning to regexp <tt>/./</tt>:
+  #
+  #     Dir.glob('io.?') # => ["io.c"]
+  #
+  # - <tt>'[set]'</tt>: Matches any one character in the string _set_;
+  #   behaves like a {Regexp character class}[rdoc-ref:Regexp@Character+Classes],
+  #   including set negation (<tt>'[^a-z]'</tt>):
+  #
+  #     Dir.glob('*.[a-z][a-z]').take(3)
+  #     # => ["CONTRIBUTING.md", "COPYING.ja", "KNOWNBUGS.rb"]
+  #
+  # - <tt>'{abc,xyz}'</tt>:
+  #   Matches either string _abc_ or string _xyz_;
+  #   behaves like {Regexp alternation}[rdoc-ref:Regexp@Alternation]:
+  #
+  #     Dir.glob('{LEGAL,BSDL}') # => ["LEGAL", "BSDL"]
+  #
+  #   More than two alternatives may be given.
+  #
+  # - <tt>\\</tt>: Escapes the following metacharacter.
+  #
+  #   Note that on Windows, the backslash character may not be used
+  #   in a string pattern:
+  #   <tt>Dir['c:\\foo*']</tt> will not work, use <tt>Dir['c:/foo*']</tt> instead.
+  #
+  # More examples (using the {simple file tree}[rdoc-ref:Dir@About+the+Examples]):
+  #
+  #   # We're in the example directory.

+  # <b>Flags</b>
+  #
+  # If optional keyword argument +flags+ is given (the default is zero -- no flags),
+  # its value should be the bitwise OR of one or more of the constants
+  # defined in module File::Constants.
+  #
+  # Example:
+  #
+  #   flags = File::FNM_EXTGLOB | File::FNM_DOTMATCH
+  #
+  # Specifying flags can extend, restrict, or otherwise modify the matching.
+  #
+  # The flags for this method (other constants in File::Constants do not apply):
+  #
+  # - File::FNM_DOTMATCH:
+  #   specifies that entry names beginning with <tt>'.'</tt>
+  #   should be considered for matching:
+  #
+  #     Dir.glob('*').take(5)
+  #     # => ["BSDL", "CONTRIBUTING.md", "COPYING", "COPYING.ja", "GPL"]
+  #     Dir.glob('*', flags: File::FNM_DOTMATCH).take(5)
+  #     # => [".", ".appveyor.yml", ".cirrus.yml", ".dir-locals.el", ".document"]
+  #
+  # - File::FNM_EXTGLOB:
+  #   enables the pattern extension
+  #   <tt>'{a,b}'</tt>, which matches pattern _a_ and pattern _b_;
+  #   behaves like a
+  #   {regexp union}[rdoc-ref:Regexp.union]
+  #   (e.g., <tt>'(?:a|b)'</tt>):
+  #
+  #     pattern = '{LEGAL,BSDL}'
+  #     Dir.glob(pattern)      # => ["LEGAL", "BSDL"]
+  #
+  # - File::FNM_NOESCAPE:
+  #   specifies that escaping with the backslash character <tt>'\'</tt>
+  #   is disabled; the character is not an escape character.
+  #
+  # - File::FNM_PATHNAME:
+  #   specifies that metacharacters <tt>'*'</tt> and <tt>'?'</tt>
+  #   do not match directory separators.
+  #
+  # - File::FNM_SHORTNAME:
+  #   specifies that patterns may match short names if they exist; Windows only.

+  #    File.fnmatch( pattern, path, [flags] ) -> (true or false)
+  #    File.fnmatch?( pattern, path, [flags] ) -> (true or false)
+  #
+  # Returns true if +path+ matches against +pattern+.  The pattern is not a
+  # regular expression; instead it follows rules similar to shell filename
+  # globbing.  It may contain the following metacharacters:
+  #
+  # <code>*</code>::
+  #   Matches any file. Can be restricted by other values in the glob.
+  #   Equivalent to <code>/.*/x</code> in regexp.
+  #
+  #   <code>*</code>::    Matches all regular files
+  #   <code>c*</code>::   Matches all files beginning with <code>c</code>
+  #   <code>*c</code>::   Matches all files ending with <code>c</code>
+  #   <code>\*c*</code>:: Matches all files that have <code>c</code> in them
+  #                       (including at the beginning or end).
+  #
+  #   To match hidden files (that start with a <code>.</code>) set the
+  #   File::FNM_DOTMATCH flag.
+  #
+  # <code>**</code>::
+  #   Matches directories recursively or files expansively.
+  #
+  # <code>?</code>::
+  #   Matches any one character. Equivalent to <code>/.{1}/</code> in regexp.
+  #
+  # <code>[set]</code>::
+  #   Matches any one character in +set+.  Behaves exactly like character sets
+  #   in Regexp, including set negation (<code>[^a-z]</code>).
+  #
+  # <code>\\</code>::
+  #   Escapes the next metacharacter.
+  #
+  # <code>{a,b}</code>::
+  #   Matches pattern a and pattern b if File::FNM_EXTGLOB flag is enabled.
+  #   Behaves like a Regexp union (<code>(?:a|b)</code>).
+  #
+  # +flags+ is a bitwise OR of the <code>FNM_XXX</code> constants. The same
+  # glob pattern and flags are used by Dir::glob.
+  #

-	* include/ruby/intern.h, thread_pthread.c (rb_reserved_fd_p,

-	* lib/benchmark.rb: merge eregon/benchmark.
-	  https://github.com/eregon/ruby/tree/benchmark
-	  patched by Benoit Daloze. [ruby-core:37593] [Bug #4940]
-
-	* lib/benchmark (Benchmark#bmbm): bmbm should be consistent with bm
-	  for the return value.
-
-	* test/benchmark: remove preemptive test instead of skipping
-	  I removed the preemptive test I wrote for Feature #4197.
-	  I'll add it back when the implementation will be able to satisfy it.
-
-	* lib/benchmark (Benchmark#bmbm): remove useless explicit call,
-	  #format is an alias of #to_s test/benchmark: add a test for
-	  format of long time.
-
-	* lib/benchmark: fix label width: always add 1 to ensure there is a
-	  space delimiter even with times over 100s
-	  When I asked for Feature #4197, I wanted to make delimiting spaces
-	  consistent for #bm and #bmbm.
-	  But with times over 100s, the output contains no space between the
-	  label and the first time (user).
-	  Now both ensure there is always a space, even if that means 3 spaces
-	  with times under 10s (because it is formatted as %10.6f)
-
-	* test/benchmark: let labels be a constant
-	  lib/benchmark (Benchmark#realtime): avoid creating an unused Proc
-	  lib/benchmark (Benchmark#benchmark): use ensure clause to restore

-	  "buff" (1024 byte) on stack may cause stack overflow on
-	  several environment (we found a crash on FreeBSD).
-	  And remove const value "buff_size", and define CCP_READ_BUFF_SIZE
-	  macro.

-	* thread_pthread.c: Stop polling in the timer thread when there are
-	  no waiting thread.  If there are 2 or more runnable threads,

-	  If outside-event such as signal or Thread#kill was occurred
-	  when the timer thread does not do polling, then wake-up

-	  waits this communication-pipe with select(2)).

-
-	* 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.

-	  Skip syslog tests that rely on LOG_PERROR unless it's defined
-
-	  Instead of checking looking at the platform to determine if the tests
-	  relying on LOG_PERROR should be run, look for the definition of the
-	  constant as this will be robust against all platforms as long as the
-	  underlying syslog.c code sets it up correctly.
-
-	  This specifically addresses failures on Solaris 9.
-
-	  Use LOG_PID instead of LOG_PERROR in Syslog.open test
-
-	  LOG_PERROR isn't a POSIX option for syslog, so it fails on platforms
-	  that don't define it.  Solaris 9 and 10 are examples of this.
-
-	  Use LOG_PID instead.

-	* 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.

-	* vm_method.c (rb_unlink_method_entry, rb_sweep_method_entry):
-	  added.  Unlinked method entries are collected to
-	  vm->unlinked_method_entry_list.  On the GC timing, mark all method
-	  entries which are on all living threads.  Only non-marked method
-	  entries are collected.  This hack prevents releasing living method
-	  entry.
-	  [Performance Consideration] Since this Method Entry GC (MEGC)
-	  doesn't occur frequently, MEGC will not be a performance bottleneck.
-	  However, to traverse living method entries, every control frame push
-	  needs to clear cfp->me field.  This will be a performance issue
-	  (because pushing control frame is occurred frequently).

-	  content in history when specifies the negative offset for the

-	  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 really 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 defined
-	  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 ignore 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 defined 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/sample/demos-jp/textpeer.rb,
-	  ext/tk/sample/demos-en/textpeer.rb: new widget demo.
-
-	* ext/tk/tcltklib.c: decrease SEGV troubles (probably)
-
-	* 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_compatibility__)
-
-	* 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: sometimes 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/tk/lib/tk.rb, ext/tk/lib/*: make default widget set
-	  switchable between Tk (standard Tcl/Tk widget set) and
-	  Ttk (Tile). Initial default widget set is Tk. Now, toplevel
-	  widget classes are removed and defined as aliases.
-	  For example, "TkButton" is an alias of the "Tk::Button" class.
-	  Those aliases are replaced when switching default widget set.
-	  "Tk.default_widget_set=" is the method for switching default
-	  widget set. "Tk.default_widget_set = :Ttk" defines Ttk (Tile)
-	  widget set as default. It means that "TkButton" denotes
-	  "Tk::Tile::Button" class. And then, "TkButton.new" creates
-	  a Tk::Tile::Button widget. Of course, you can back to use
-	  standard Tk widgets as the default widget set by calling
-	  "Tk.default_widget_set = :Tk", whenever you want. Based on
-	  the feature, you can use Ttk widget styling engine on your
-	  old Ruby/Tk application without modifying its source, if you
-	  don't use widget options unsupported on Ttk widgets (At first,
-	  call "Tk.default_widget_set = :Ttk", and next load and run
-	  your application).
-	  This is one step for supporting Tcl/Tk8.5 features.

-	  convenient instance methods such as "new()", for creating a new
-	  copy, parameter taking "digest()" and "hexdigest()", for instant
-	  calculation.  These methods make digest instances work just like
-	  digest classes.
-
-	* ext/digest/sha2/lib/digest/sha2.rb:
-	  Add the Digest::SHA2 class to wrap up SHA2 variants: SHA256,

-
-	* ext/digest/lib/digest/hmac.rb: Completely redesign the somewhat

-	* ext/digest/digest.c (Init_digest): Digest::Base.new() does no
-	  longer take an initial string to feed.  This change allows
-	  subclasses to take hashing parameters.  A statement such as

-	  ``md = Digest::MD5.new << s'' or
-	  ``md = Digest::MD5.new.update(s)''.

-
-Thu Oct 12 02:12:31 2006  Akinori MUSHA  <knu@iDaemons.org>
-
-	* ext/digest/digest.c (get_digest_base_metadata): Use an instance
-	  variable of a class object instead of a class variable for
-	  metadata.  This change is only crucial for ruby 1.8 because
-	  class variables are inherited to subclasses prior to 1.9, but

-
-Mon Dec 19 23:09:24 2005  Hirokazu Yamamoto  <ocean@m2.ccsnet.ne.jp>
-
-	* st.c: uses malloc instead of xmalloc to avoid GC. syck uses st_insert
-	  in gram.c to insert node from rb_syck_bad_anchor_handler into
-	  SyckParser's hash table. if GC occurs in st_insert, it's not under
-	  SyckParser's mark system yet. so RString can be released wrongly.
-
-	* ext/syck/syck.h (S_FREE): small hack. no need to check if pointer is
-	  NULL or not before S_FREE.
-
-	* ext/syck/rubyext.c (syck_parser_assign_io): rb_check_string_type can
-	  return new RString. if so, it becomes unreachable from GC after
-	  returns syck_parser_assign_io, and can be freed by GC. (dangling
-	  in syck io system) so extends its life time till syck_parse is called.
-
-	* ext/syck/rubyext.c (syck_parser_s_alloc): always allocates bonus,
-	  so no need to check if NULL, and "volatile VALUE hash"
-	  is not needed. (bonus->port was not protected in syck_emitter_reset)

-	* ext/syck/rubyext.c (syck_mark_parser): ditto.

-
-	* ext/syck/rubyext.c: sorry, I reverted my "should set newly
-	  allocated memory instead of RString's internal storage" stuff.
-	  node allocated in rubyext.c seems to be freed by rb_syck_free_node
-	  not syck_free_node, and it won't free data.str->ptr and type_id.
-
-	 (I still think this is unsafe because RString(foo)->ptr becomes
-	  dangling pointer when RString is modified or freed, but anyway
-	  I misunderstood, so go back to original code for now)

-
-	* win32/win32.c (rb_w32_select): fixed deadlock bug.
-	  because select(2) modifies its fd_set arguments, it must be
-	  restored sometimes.
-
-	* win32/win32.c (rb_w32_select): performance improvement when
-	 'always readable/writable handles' and sockets are passed.
-	  sockets should be polled every time.
-
-	    require "net/http"
-
-	    Thread.new {
-	      loop do

-
-	* win32/win32.c (rb_w32_select): console support is back.
-	  but still has performance problem because I loosely took 1 second
-	  for wait time. I'll fix it later. (The reason I drastically changed
-	  the code is that I wanted to implement the fileset management as
-	  single function, and I was worried that if pipe or console
-	  was always available, socket may not be processed any time)
-
-Sat Sep 17 11:24:16 2005  Hirokazu Yamamoto  <ocean@m2.ccsnet.ne.jp>
-
-	* win32/win32.c (rb_w32_select): select for socket didn't work.
-	  this caused deadlock in drb test. this happened because GetFileType
-	  for socket handle returns FILE_TYPE_PIPE. Of course, it's not a
-	  pipe. So socket handle didn't reach winsock's select function.
-
-	* win32/win32.c (rb_w32_select): read for pipe was still blocked
-	  even if writer handle was closed.
-
-	    r,w = IO.pipe
-
-	    Thread.new {
-	      sleep 3; puts "------- 1"
-	      w.puts("foo")
-	      sleep 3; puts "------- 2"
-	      w.puts("boo")
-	      sleep 3; puts "------- 3"
-	      w.close
-	    }
-
-	    until r.eof? # should break by w.close but didn't.
-	      puts r.gets
-	    end
-
-	* win32/win32.c (rb_w32_select): temporary reverted console support
-	  but it'll be back soon.

-
-	* ext/tk/lib/multi-tk.rb: MultiTkIp#eval_string and bg_eval_string
-	  should call Kernel.eval on caller's safe-level instead of slave's
-	  safe-level (Of course, the given script should be evaluated on
-	  slave's safe-level).

-Sat Sep 17 09:45:26 2005  Yukihiro Matsumoto  <matz@ruby-lang.org>

-	  Daniel Berger.
-
-	* lib/logger.rb (Logger): added VERSION constant.
-
-	* lib/logger.rb: removed document for LogDevice. It is an

-	* ext/syck/rubyext.c: new emitter code.  yaml_new and yaml_initialize
-	  get called, should they be present.  consolidated all the diaspora of 	  internal node types into the family below YAML::Syck::Node -- Map,
-	  Seq, Scalar -- all of whom are SyckNode structs pointing to
-	  Ruby data.  moved Object#yaml_new into the node_import and made it
-	  the default behavior.  the target_class is always called with
-	  yaml_new, prepended a parameter, which is the klass.  loaded nodes
-	  through GenericResolver show their style.
-	  new Resolver#tagurize converts type ids to taguris.
-
-	* ext/syck/implicit.re: were 'y' and 'n' seriously omitted??
-
-	* ext/syck/emitter.c: renovated emitter, walks the tree in advance.
-	  consolidated redundant block_styles struct into
-	  the scalar_style struct.  (this means loaded nodes can now
-	  be sent back to emitter and preserve at least its very basic
-	  formatting.)
-
-	* ext/syck/gram.c: headless documents of any kind allowed.
-
-	* ext/syck/node.c: new syck_replace_str methods and syck_empty_*
-	  methods for rewriting node contents, while keeping the ID
-	  and other setup info.  added syck_seq_assign.
-
-	* ext/syck/syck.h: reflect block_styles and new node functions.

-
-	* 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.

-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().
