+# RDoc uses generators to turn parsed source code in the form of an
+# RDoc::CodeObject tree into some form of output.  RDoc comes with the HTML
+# generator RDoc::Generator::Darkfish and an ri data generator
+# RDoc::Generator::RI.
+#
+# == Registering a Generator
+#
+# Generators are registered by calling RDoc::RDoc.add_generator with the class
+# of the generator:
+#
+#   class My::Awesome::Generator
+#     RDoc::RDoc.add_generator self
+#   end
+#
+# == Adding Options to +rdoc+
+#
+# Before option processing in +rdoc+, RDoc::Options will call ::setup_options
+# on the generator class with an RDoc::Options instance.  The generator can
+# use RDoc::Options#option_parser to add command-line options to the +rdoc+
+# tool.  See RDoc::Options@Custom+Options for an example and see OptionParser
+# for details on how to add options.
+#
+# You can extend the RDoc::Options instance with additional accessors for your
+# generator.
+#
+# == Generator Instantiation
+#
+# After parsing, RDoc::RDoc will instantiate a generator by calling
+# #initialize with an RDoc::Store instance and an RDoc::Options instance.
+#
+# The RDoc::Store instance holds documentation for parsed source code.  In
+# RDoc 3 and earlier the RDoc::TopLevel class held this data.  When upgrading
+# a generator from RDoc 3 and earlier you should only need to replace
+# RDoc::TopLevel with the store instance.
+#
+# RDoc will then call #generate on the generator instance.  You can use the
+# various methods on RDoc::Store and in the RDoc::CodeObject tree to create
+# your desired output format.

+#
+#   var search_data = {
+#     "index": {
+#       "searchIndex":
+#         ["a", "b", ...],
+#       "longSearchIndex":
+#         ["a", "a::b", ...],
+#       "info": [
+#         ["A", "A", "A.html", "", ""],
+#         ["B", "A::B", "A::B.html", "", ""],
+#         ...
+#       ]
+#     }
+#   }
+#
+# The same item is described across the +searchIndex+, +longSearchIndex+ and
+# +info+ fields.  The +searchIndex+ field contains the item's short name, the
+# +longSearchIndex+ field contains the full_name (when appropriate) and the
+# +info+ field contains the item's name, full_name, path, parameters and a
+# snippet of the item's comment.

+# == Create .pot
+#

+#
+#   % rdoc --format pot
+#
+# It generates doc/rdoc.pot.
+#
+# == Create .po
+#
+# You create .po file from doc/rdoc.pot. This operation is needed only
+# the first time. This work flow assumes that you are a translator
+# for Japanese.
+#
+# You create locale/ja/rdoc.po from doc/rdoc.pot. You can use msginit
+# provided by GNU gettext or rmsginit provided by gettext gem. This
+# work flow uses gettext gem because it is more portable than GNU
+# gettext for Rubyists. Gettext gem is implemented by pure Ruby.
+#
+#   % gem install gettext
+#   % mkdir -p locale/ja
+#   % rmsginit --input doc/rdoc.pot --output locale/ja/rdoc.po --locale ja
+#
+# Translate messages in .po
+#
+# You translate messages in .po by a PO file editor. po-mode.el exists
+# for Emacs users. There are some GUI tools such as GTranslator.
+# There are some Web services such as POEditor and Tansifex. You can
+# edit by your favorite text editor because .po is a text file.
+# Generate localized documentation
+#
+# You can generate localized documentation with locale/ja/rdoc.po:
+#
+#   % rdoc --locale ja
+#
+# You can find documentation in Japanese in doc/. Yay!
+#
+# == Update translation
+#
+# You need to update translation when your application is added or
+# modified messages.
+#
+# You can update .po by the following command lines:
+#
+#   % rdoc --format pot
+#   % rmsgmerge --update locale/ja/rdoc.po doc/rdoc.pot

+ * SIL OPEN FONT LICENSE Version 1.1 - 26 February 2007
+ * -----------------------------------------------------------
+ *
+ * PREAMBLE
+ * The goals of the Open Font License (OFL) are to stimulate worldwide
+ * development of collaborative font projects, to support the font creation
+ * efforts of academic and linguistic communities, and to provide a free and
+ * open framework in which fonts may be shared and improved in partnership
+ * with others.
+ *
+ * The OFL allows the licensed fonts to be used, studied, modified and
+ * redistributed freely as long as they are not sold by themselves. The
+ * fonts, including any derivative works, can be bundled, embedded,
+ * redistributed and/or sold with any software provided that any reserved
+ * names are not used by derivative works. The fonts and derivatives,
+ * however, cannot be released under any other type of license. The
+ * requirement for fonts to remain under this license does not apply
+ * to any document created using the fonts or their derivatives.
+ *
+ * DEFINITIONS
+ * "Font Software" refers to the set of files released by the Copyright
+ * Holder(s) under this license and clearly marked as such. This may
+ * include source files, build scripts and documentation.
+ *
+ * "Reserved Font Name" refers to any names specified as such after the
+ * copyright statement(s).
+ *
+ * "Original Version" refers to the collection of Font Software components as
+ * distributed by the Copyright Holder(s).
+ *
+ * "Modified Version" refers to any derivative made by adding to, deleting,
+ * or substituting -- in part or in whole -- any of the components of the
+ * Original Version, by changing formats or by porting the Font Software to a
+ * new environment.
+ *
+ * "Author" refers to any designer, engineer, programmer, technical
+ * writer or other person who contributed to the Font Software.
+ *
+ * PERMISSION & CONDITIONS
+ * Permission is hereby granted, free of charge, to any person obtaining
+ * a copy of the Font Software, to use, study, copy, merge, embed, modify,
+ * redistribute, and sell modified and unmodified copies of the Font
+ * Software, subject to the following conditions:
+ *
+ * 1) Neither the Font Software nor any of its individual components,
+ * in Original or Modified Versions, may be sold by itself.
+ *
+ * 2) Original or Modified Versions of the Font Software may be bundled,
+ * redistributed and/or sold with any software, provided that each copy
+ * contains the above copyright notice and this license. These can be
+ * included either as stand-alone text files, human-readable headers or
+ * in the appropriate machine-readable metadata fields within text or
+ * binary files as long as those fields can be easily viewed by the user.
+ *
+ * 3) No Modified Version of the Font Software may use the Reserved Font
+ * Name(s) unless explicit written permission is granted by the corresponding
+ * Copyright Holder. This restriction only applies to the primary font name as
+ * presented to the users.
+ *
+ * 4) The name(s) of the Copyright Holder(s) or the Author(s) of the Font
+ * Software shall not be used to promote, endorse or advertise any
+ * Modified Version, except to acknowledge the contribution(s) of the
+ * Copyright Holder(s) and the Author(s) or with their explicit written
+ * permission.
+ *
+ * 5) The Font Software, modified or unmodified, in part or in whole,
+ * must be distributed entirely under this license, and must not be
+ * distributed under any other license. The requirement for fonts to
+ * remain under this license does not apply to any document created
+ * using the Font Software.
+ *
+ * TERMINATION
+ * This license becomes null and void if any of the above conditions are
+ * not met.
+ *
+ * DISCLAIMER
+ * THE FONT SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND,

+# RDoc::Markdown as described by the [markdown syntax][syntax].
+#
+# To choose Markdown as your only default format see
+# RDoc::Options@Saved+Options for instructions on setting up a `.doc_options`
+# file to store your project default.
+#
+# ## Usage
+#
+# Here is a brief example of using this parse to read a markdown file by hand.
+#
+#     data = File.read("README.md")
+#     formatter = RDoc::Markup::ToHtml.new(RDoc::Options.new, nil)
+#     html = RDoc::Markdown.parse(data).accept(@formatter)
+#
+#     # do something with html
+#
+# ## Extensions
+#
+# The following markdown extensions are supported by the parser, but not all
+# are used in RDoc output by default.
+#
+# ### RDoc
+#
+# The RDoc Markdown parser has the following built-in behaviors that cannot be
+# disabled.
+#
+# Underscores embedded in words are never interpreted as emphasis.  (While the
+# [markdown dingus][dingus] emphasizes in-word underscores, neither the
+# Markdown syntax nor MarkdownTest mention this behavior.)
+#
+# For HTML output, RDoc always auto-links bare URLs.
+#
+# ### Break on Newline
+#
+# The break_on_newline extension converts all newlines into hard line breaks
+# as in [Github Flavored Markdown][GFM].  This extension is disabled by
+# default.
+#
+# ### CSS
+#
+# The #css extension enables CSS blocks to be included in the output, but they
+# are not used for any built-in RDoc output format.  This extension is disabled
+# by default.
+#
+# Example:
+#
+#     <style type="text/css">
+#     h1 { font-size: 3em }
+#     </style>
+#
+# ### Definition Lists
+#
+# The definition_lists extension allows definition lists using the [PHP
+# Markdown Extra syntax][PHPE], but only one label and definition are supported
+# at this time.  This extension is enabled by default.
+#
+# Example:
+#
+# ```
+# cat
+# :   A small furry mammal
+# that seems to sleep a lot
+#
+# ant
+# :   A little insect that is known
+# to enjoy picnics
+#
+# ```
+#
+# Produces:
+#
+# cat
+# :   A small furry mammal
+# that seems to sleep a lot
+#
+# ant
+# :   A little insect that is known
+# to enjoy picnics
+#
+# ### Github
+#
+# The #github extension enables a partial set of [Github Flavored Markdown]
+# [GFM].  This extension is enabled by default.
+#
+# Supported github extensions include:
+#
+# #### Fenced code blocks
+#
+# Use ` ``` ` around a block of code instead of indenting it four spaces.
+#
+# #### Syntax highlighting
+#
+# Use ` ``` ruby ` as the start of a code fence to add syntax highlighting.
+# (Currently only `ruby` syntax is supported).
+#
+# ### HTML
+#
+# Enables raw HTML to be included in the output.  This extension is enabled by
+# default.
+#
+# Example:
+#
+#     <table>
+#     ...
+#     </table>
+#
+# ### Notes
+#
+# The #notes extension enables footnote support.  This extension is enabled by
+# default.
+#
+# Example:
+#
+#     Here is some text[^1] including an inline footnote ^[for short footnotes]
+#
+#     ...
+#
+#     [^1]: With the footnote text down at the bottom
+#
+# Produces:
+#
+# Here is some text[^1] including an inline footnote ^[for short footnotes]
+#
+# [^1]: With the footnote text down at the bottom
+#
+# ## Limitations
+#
+# * Link titles are not used
+# * Footnotes are collapsed into a single paragraph

+# RDoc::Markup parses plain text documents and attempts to decompose them into
+# their constituent parts.  Some of these parts are high-level: paragraphs,
+# chunks of verbatim text, list entries and the like.  Other parts happen at
+# the character level: a piece of bold text, a word in code font.  This markup
+# is similar in spirit to that used on WikiWiki webs, where folks create web
+# pages using a simple set of formatting rules.
+#
+# RDoc::Markup and other markup formats do no output formatting, this is
+# handled by the RDoc::Markup::Formatter subclasses.
+#
+# = Supported Formats
+#
+# Besides the RDoc::Markup format, the following formats are built in to RDoc:
+#
+# markdown::
+#   The markdown format as described by
+#   http://daringfireball.net/projects/markdown/.  See RDoc::Markdown for
+#   details on the parser and supported extensions.
+# rd::
+#   The rdtool format.  See RDoc::RD for details on the parser and format.
+# tomdoc::
+#   The TomDoc format as described by http://tomdoc.org/.  See RDoc::TomDoc
+#   for details on the parser and supported extensions.
+#
+# You can choose a markup format using the following methods:
+#
+# per project::
+#   If you build your documentation with rake use RDoc::Task#markup.
+#
+#   If you build your documentation by hand run:
+#
+#      rdoc --markup your_favorite_format --write-options
+#
+#   and commit <tt>.rdoc_options</tt> and ship it with your packaged gem.
+# per file::
+#   At the top of the file use the <tt>:markup:</tt> directive to set the
+#   default format for the rest of the file.
+# per comment::
+#   Use the <tt>:markup:</tt> directive at the top of a comment you want
+#   to write in a different format.
+#
+# = RDoc::Markup
+#
+# RDoc::Markup is extensible at runtime: you can add \new markup elements to
+# be recognized in the documents that RDoc::Markup parses.
+#
+# RDoc::Markup is intended to be the basis for a family of tools which share
+# the common requirement that simple, plain-text should be rendered in a
+# variety of different output formats and media.  It is envisaged that
+# RDoc::Markup could be the basis for formatting RDoc style comment blocks,
+# Wiki entries, and online FAQs.
+#
+# == Synopsis
+#
+# This code converts +input_string+ to HTML.  The conversion takes place in
+# the +convert+ method, so you can use the same RDoc::Markup converter to
+# convert multiple input strings.
+#
+#   require 'rdoc'
+#
+#   h = RDoc::Markup::ToHtml.new(RDoc::Options.new)
+#
+#   puts h.convert(input_string)
+#
+# You can extend the RDoc::Markup parser to recognize new markup
+# sequences, and to add special processing for text that matches a
+# regular expression.  Here we make WikiWords significant to the parser,
+# and also make the sequences {word} and \<no>text...</no> signify
+# strike-through text.  We then subclass the HTML output class to deal
+# with these:
+#
+#   require 'rdoc'
+#
+#   class WikiHtml < RDoc::Markup::ToHtml
+#     def handle_special_WIKIWORD(special)
+#       "<font color=red>" + special.text + "</font>"
+#     end
+#   end
+#
+#   markup = RDoc::Markup.new
+#   markup.add_word_pair("{", "}", :STRIKE)
+#   markup.add_html("no", :STRIKE)
+#
+#   markup.add_special(/\b([A-Z][a-z]+[A-Z]\w+)/, :WIKIWORD)
+#
+#   wh = WikiHtml.new RDoc::Options.new, markup
+#   wh.add_tag(:STRIKE, "<strike>", "</strike>")
+#
+#   puts "<body>#{wh.convert ARGF.read}</body>"
+#
+# == Encoding
+#
+# Where Encoding support is available, RDoc will automatically convert all
+# documents to the same output encoding.  The output encoding can be set via
+# RDoc::Options#encoding and defaults to Encoding.default_external.
+#
+# = \RDoc Markup Reference
+#
+# == Block Markup
+#
+# === Paragraphs and Verbatim
+#
+# The markup engine looks for a document's natural left margin.  This is
+# used as the initial margin for the document.
+#
+# Consecutive lines starting at this margin are considered to be a
+# paragraph. Empty lines separate paragraphs.
+#
+# Any line that starts to the right of the current margin is treated
+# as verbatim text.  This is useful for code listings:
+#
+#   3.times { puts "Ruby" }
+#
+# In verbatim text, two or more blank lines are collapsed into one,
+# and trailing blank lines are removed:
+#
+#   This is the first line
+#
+#
+#   This is the second non-blank line,
+#   after 2 blank lines in the source markup.
+#
+#
+# There were two trailing blank lines right above this paragraph, that
+# have been removed. In addition, the verbatim text has been shifted
+# left, so the amount of indentation of verbatim text is unimportant.
+#
+# For HTML output RDoc makes a small effort to determine if a verbatim section
+# contains Ruby source code.  If so, the verbatim block will be marked up as
+# HTML.  Triggers include "def", "class", "module", "require", the "hash
+# rocket"# (=>) or a block call with a parameter.
+#
+# === Headers
+#
+# A line starting with an equal sign (=) is treated as a
+# heading.  Level one headings have one equals sign, level two headings
+# have two, and so on until level six, which is the maximum
+# (seven hyphens or more result in a level six heading).
+#
+# For example, the above header was obtained with:
+#
+#   === Headers
+#
+# In HTML output headers have an id matching their name.  The above example's
+# HTML is:
+#
+#   <h3 id="label-Headers">Headers</h3>
+#
+# If a heading is inside a method body the id will be prefixed with the
+# method's id.  If the above header where in the documentation for a method
+# such as:
+#
+#   ##
+#   # This method does fun things
+#   #
+#   # = Example
+#   #
+#   #   Example of fun things goes here ...
+#
+#   def do_fun_things
+#   end
+#
+# The header's id would be:
+#
+#   <h1 id="method-i-do_fun_things-label-Example">Example</h1>
+#
+# The label can be linked-to using <tt>SomeClass@Headers</tt>.  See
+# {Links}[RDoc::Markup@Links] for further details.
+#
+# === Rules
+#
+# A line starting with three or more hyphens (at the current indent)
+# generates a horizontal rule.
+#
+#   ---
+#
+# produces:
+#
+# ---
+#
+# === Simple Lists
+#
+# If a paragraph starts with a "*", "-", "<digit>." or "<letter>.",
+# then it is taken to be the start of a list.  The margin is increased to be
+# the first non-space following the list start flag.  Subsequent lines
+# should be indented to this new margin until the list ends.  For example:
+#
+#   * this is a list with three paragraphs in
+#     the first item.  This is the first paragraph.
+#
+#     And this is the second paragraph.
+#
+#     1. This is an indented, numbered list.
+#     2. This is the second item in that list
+#
+#     This is the third conventional paragraph in the
+#     first list item.
+#
+#   * This is the second item in the original list
+#
+# produces:
+#
+# * this is a list with three paragraphs in
+#   the first item.  This is the first paragraph.
+#
+#   And this is the second paragraph.
+#
+#   1. This is an indented, numbered list.
+#   2. This is the second item in that list
+#
+#   This is the third conventional paragraph in the
+#   first list item.
+#
+# * This is the second item in the original list
+#
+# === Labeled Lists
+#
+# You can also construct labeled lists, sometimes called description
+# or definition lists.  Do this by putting the label in square brackets
+# and indenting the list body:
+#
+#   [cat]  a small furry mammal
+#          that seems to sleep a lot
+#
+#   [ant]  a little insect that is known
+#          to enjoy picnics
+#
+# produces:
+#
+# [cat]  a small furry mammal
+#        that seems to sleep a lot
+#
+# [ant]  a little insect that is known
+#        to enjoy picnics
+#
+# If you want the list bodies to line up to the left of the labels,
+# use two colons:
+#
+#   cat::  a small furry mammal
+#          that seems to sleep a lot
+#
+#   ant::  a little insect that is known
+#          to enjoy picnics
+#
+# produces:
+#
+# cat::  a small furry mammal
+#        that seems to sleep a lot
+#
+# ant::  a little insect that is known
+#        to enjoy picnics
+#
+# Notice that blank lines right after the label are ignored in labeled lists:
+#
+#   [one]
+#
+#       definition 1
+#
+#   [two]
+#
+#       definition 2
+#
+# produces the same output as
+#
+#   [one]  definition 1
+#   [two]  definition 2
+#
+#
+# === Lists and Verbatim
+#
+# If you want to introduce a verbatim section right after a list, it has to be
+# less indented than the list item bodies, but more indented than the list
+# label, letter, digit or bullet. For instance:
+#
+#   *   point 1
+#
+#   *   point 2, first paragraph
+#
+#       point 2, second paragraph
+#         verbatim text inside point 2
+#       point 2, third paragraph
+#     verbatim text outside of the list (the list is therefore closed)
+#   regular paragraph after the list
+#
+# produces:
+#
+# *   point 1
+#
+# *   point 2, first paragraph
+#
+#     point 2, second paragraph
+#       verbatim text inside point 2
+#     point 2, third paragraph
+#   verbatim text outside of the list (the list is therefore closed)
+# regular paragraph after the list
+#
+# == Text Markup
+#
+# === Bold, Italic, Typewriter Text
+#
+# You can use markup within text (except verbatim) to change the
+# appearance of parts of that text.  Out of the box, RDoc::Markup
+# supports word-based and general markup.
+#
+# Word-based markup uses flag characters around individual words:
+#
+# <tt>\*_word_\*</tt>::  displays _word_ in a *bold* font
+# <tt>\__word_\_</tt>::  displays _word_ in an _emphasized_ font
+# <tt>\+_word_\+</tt>::  displays _word_ in a +code+ font
+#
+# General markup affects text between a start delimiter and an end
+# delimiter.  Not surprisingly, these delimiters look like HTML markup.
+#
+# <tt>\<b>_text_</b></tt>::    displays _text_ in a *bold* font
+# <tt>\<em>_text_</em></tt>::  displays _text_ in an _emphasized_ font
+#                              (alternate tag: <tt>\<i></tt>)
+# <tt>\<tt>_text_\</tt></tt>:: displays _text_ in a +code+ font
+#                              (alternate tag: <tt>\<code></tt>)
+#
+# Unlike conventional Wiki markup, general markup can cross line
+# boundaries.  You can turn off the interpretation of markup by
+# preceding the first character with a backslash (see <i>Escaping
+# Text Markup</i>, below).
+#
+# === Links
+#
+# Links to starting with +http:+, +https:+, +mailto:+, +ftp:+ or +www.+
+# are recognized.  An HTTP url that references an external image is converted
+# into an inline image element.
+#
+# Classes and methods will be automatically linked to their definition.  For
+# example, <tt>RDoc::Markup</tt> will link to this documentation.  By default
+# methods will only be automatically linked if they contain an <tt>_</tt> (all
+# methods can be automatically linked through the <tt>--hyperlink-all</tt>
+# command line option).
+#
+# Single-word methods can be linked by using the <tt>#</tt> character for
+# instance methods or <tt>::</tt> for class methods.  For example,
+# <tt>#convert</tt> links to #convert.  A class or method may be combined like
+# <tt>RDoc::Markup#convert</tt>.
+#
+# A heading inside the documentation can be linked by following the class
+# or method by an <tt>@</tt> then the heading name.
+# <tt>RDoc::Markup@Links</tt> will link to this section like this:
+# RDoc::Markup@Links.  Spaces in headings with multiple words must be escaped
+# with <tt>+</tt> like <tt>RDoc::Markup@Escaping+Text+Markup</tt>.
+# Punctuation and other special characters must be escaped like CGI.escape.
+#
+# The <tt>@</tt> can also be used to link to sections.  If a section and a
+# heading share the same name the section is preferred for the link.
+#
+# Links can also be of the form <tt>label[url]</tt>, in which case +label+ is
+# used in the displayed text, and +url+ is used as the target.  If +label+
+# contains multiple words, put it in braces: <tt>{multi word label}[url]</tt>.
+# The +url+ may be an +http:+-type link or a cross-reference to a class,
+# module or method with a label.
+#
+# Links with the <code>rdoc-image:</code> scheme will create an image tag for
+# HTML output.  Only fully-qualified URLs are supported.
+#
+# Links with the <tt>rdoc-ref:</tt> scheme will link to the referenced class,
+# module, method, file, etc.  If the referenced item is does not exist
+# no link will be generated and <tt>rdoc-ref:</tt> will be removed from the
+# resulting text.
+#
+# Links starting with <tt>rdoc-label:label_name</tt> will link to the
+# +label_name+.  You can create a label for the current link (for
+# bidirectional links) by supplying a name for the current link like
+# <tt>rdoc-label:label-other:label-mine</tt>.
+#
+# Links starting with +link:+ refer to local files whose path is relative to
+# the <tt>--op</tt> directory.  Use <tt>rdoc-ref:</tt> instead of
+# <tt>link:</tt> to link to files generated by RDoc as the link target may
+# be different across RDoc generators.
+#
+# Example links:
+#
+#   https://github.com/rdoc/rdoc
+#   mailto:user@example.com
+#   {RDoc Documentation}[http://rdoc.rubyforge.org]
+#   {RDoc Markup}[rdoc-ref:RDoc::Markup]
+#
+# === Escaping Text Markup
+#
+# Text markup can be escaped with a backslash, as in \<tt>, which was obtained
+# with <tt>\\<tt></tt>.  Except in verbatim sections and between \<tt> tags,
+# to produce a backslash you have to double it unless it is followed by a
+# space, tab or newline. Otherwise, the HTML formatter will discard it, as it
+# is used to escape potential links:
+#
+#   * The \ must be doubled if not followed by white space: \\.
+#   * But not in \<tt> tags: in a Regexp, <tt>\S</tt> matches non-space.
+#   * This is a link to {ruby-lang}[www.ruby-lang.org].
+#   * This is not a link, however: \{ruby-lang.org}[www.ruby-lang.org].
+#   * This will not be linked to \RDoc::RDoc#document
+#
+# generates:
+#
+# * The \ must be doubled if not followed by white space: \\.
+# * But not in \<tt> tags: in a Regexp, <tt>\S</tt> matches non-space.
+# * This is a link to {ruby-lang}[www.ruby-lang.org]
+# * This is not a link, however: \{ruby-lang.org}[www.ruby-lang.org]
+# * This will not be linked to \RDoc::RDoc#document
+#
+# Inside \<tt> tags, more precisely, leading backslashes are removed only if
+# followed by a markup character (<tt><*_+</tt>), a backslash, or a known link
+# reference (a known class or method). So in the example above, the backslash
+# of <tt>\S</tt> would be removed if there was a class or module named +S+ in
+# the current context.
+#
+# This behavior is inherited from RDoc version 1, and has been kept for
+# compatibility with existing RDoc documentation.
+#
+# === Conversion of characters
+#
+# HTML will convert two/three dashes to an em-dash. Other common characters are
+# converted as well:
+#
+#   em-dash::  -- or ---
+#   ellipsis:: ...
+#
+#   single quotes:: 'text' or `text'
+#   double quotes:: "text" or ``text''
+#
+#   copyright:: (c)
+#   registered trademark:: (r)
+#
+# produces:
+#
+# em-dash::  -- or ---
+# ellipsis:: ...
+#
+# single quotes:: 'text' or `text'
+# double quotes:: "text" or ``text''
+#
+# copyright:: (c)
+# registered trademark:: (r)
+#
+#
+# == Documenting Source Code
+#
+# Comment blocks can be written fairly naturally, either using <tt>#</tt> on
+# successive lines of the comment, or by including the comment in
+# a <tt>=begin</tt>/<tt>=end</tt> block.  If you use the latter form,
+# the <tt>=begin</tt> line _must_ be flagged with an +rdoc+ tag:
+#
+#   =begin rdoc
+#   Documentation to be processed by RDoc.
+#
+#   ...
+#   =end
+#
+# RDoc stops processing comments if it finds a comment line starting
+# with <tt>--</tt> right after the <tt>#</tt> character (otherwise,
+# it will be treated as a rule if it has three dashes or more).
+# This can be used to separate external from internal comments,
+# or to stop a comment being associated with a method, class, or module.
+# Commenting can be turned back on with a line that starts with <tt>++</tt>.
+#
+#   ##
+#   # Extract the age and calculate the date-of-birth.
+#   #--
+#   # FIXME: fails if the birthday falls on February 29th
+#   #++
+#   # The DOB is returned as a Time object.
+#
+#   def get_dob(person)
+#     # ...
+#   end
+#
+# Names of classes, files, and any method names containing an underscore or
+# preceded by a hash character are automatically linked from comment text to
+# their description. This linking works inside the current class or module,
+# and with ancestor methods (in included modules or in the superclass).
+#
+# Method parameter lists are extracted and displayed with the method
+# description.  If a method calls +yield+, then the parameters passed to yield
+# will also be displayed:
+#
+#   def fred
+#     ...
+#     yield line, address
+#
+# This will get documented as:
+#
+#   fred() { |line, address| ... }
+#
+# You can override this using a comment containing ':yields: ...' immediately
+# after the method definition
+#
+#   def fred # :yields: index, position
+#     # ...
+#
+#     yield line, address
+#
+# which will get documented as
+#
+#    fred() { |index, position| ... }
+#
+# +:yields:+ is an example of a documentation directive.  These appear
+# immediately after the start of the document element they are modifying.
+#
+# RDoc automatically cross-references words with underscores or camel-case.
+# To suppress cross-references, prefix the word with a \ character.  To
+# include special characters like "<tt>\n</tt>", you'll need to use
+# two \ characters in normal text, but only one in \<tt> text:
+#
+#   "\\n" or "<tt>\n</tt>"
+#
+# produces:
+#
+# "\\n" or "<tt>\n</tt>"
+#
+# == Directives
+#
+# Directives are keywords surrounded by ":" characters.
+#
+# === Controlling what is documented
+#
+# [+:nodoc:+ / <tt>:nodoc: all</tt>]
+#   This directive prevents documentation for the element from
+#   being generated.  For classes and modules, methods, aliases,
+#   constants, and attributes directly within the affected class or
+#   module also will be omitted.  By default, though, modules and
+#   classes within that class or module _will_ be documented.  This is
+#   turned off by adding the +all+ modifier.
+#
+#     module MyModule # :nodoc:
+#       class Input
+#       end
+#     end
+#
+#     module OtherModule # :nodoc: all
+#       class Output
+#       end
+#     end
+#
+#   In the above code, only class <tt>MyModule::Input</tt> will be documented.
+#
+#   The +:nodoc:+ directive, like +:enddoc:+, +:stopdoc:+ and +:startdoc:+
+#   presented below, is local to the current file: if you do not want to
+#   document a module that appears in several files, specify +:nodoc:+ on each
+#   appearance, at least once per file.
+#
+# [+:stopdoc:+ / +:startdoc:+]
+#   Stop and start adding new documentation elements to the current container.
+#   For example, if a class has a number of constants that you don't want to
+#   document, put a +:stopdoc:+ before the first, and a +:startdoc:+ after the
+#   last.  If you don't specify a +:startdoc:+ by the end of the container,
+#   disables documentation for the rest of the current file.
+#
+# [+:doc:+]
+#   Forces a method or attribute to be documented even if it wouldn't be
+#   otherwise.  Useful if, for example, you want to include documentation of a
+#   particular private method.
+#
+# [+:enddoc:+]
+#   Document nothing further at the current level: directives +:startdoc:+ and
+#   +:doc:+ that appear after this will not be honored for the current container
+#   (file, class or module), in the current file.
+#
+# [+:notnew:+ / +:not_new:+ / +:not-new:+ ]
+#   Only applicable to the +initialize+ instance method.  Normally RDoc
+#   assumes that the documentation and parameters for +initialize+ are
+#   actually for the +new+ method, and so fakes out a +new+ for the class.
+#   The +:notnew:+ directive stops this.  Remember that +initialize+ is private,
+#   so you won't see the documentation unless you use the +-a+ command line
+#   option.
+#
+# === Method arguments
+#
+# [+:arg:+ or +:args:+ _parameters_]
+#   Overrides the default argument handling with exactly these parameters.
+#
+#     ##
+#     #  :args: a, b
+#
+#     def some_method(*a)
+#     end
+#
+# [+:yield:+ or +:yields:+ _parameters_]
+#   Overrides the default yield discovery with these parameters.
+#
+#     ##
+#     # :yields: key, value
+#
+#     def each_thing &block
+#       @things.each(&block)
+#     end
+#
+# [+:call-seq:+]
+#   Lines up to the next blank line or lines with a common prefix in the
+#   comment are treated as the method's calling sequence, overriding the
+#   default parsing of method parameters and yield arguments.
+#
+#   Multiple lines may be used.
+#
+#     # :call-seq:
+#     #   ARGF.readlines(sep=$/)     -> array
+#     #   ARGF.readlines(limit)      -> array
+#     #   ARGF.readlines(sep, limit) -> array
+#     #
+#     #   ARGF.to_a(sep=$/)     -> array
+#     #   ARGF.to_a(limit)      -> array
+#     #   ARGF.to_a(sep, limit) -> array
+#     #
+#     # The remaining lines are documentation ...
+#
+# === Sections
+#
+# Sections allow you to group methods in a class into sensible containers.  If
+# you use the sections 'Public', 'Internal' and 'Deprecated' (the three
+# allowed method statuses from TomDoc) the sections will be displayed in that
+# order placing the most useful methods at the top.  Otherwise, sections will
+# be displayed in alphabetical order.
+#
+# [+:category:+ _section_]
+#   Adds this item to the named +section+ overriding the current section.  Use
+#   this to group methods by section in RDoc output while maintaining a
+#   sensible ordering (like alphabetical).
+#
+#     # :category: Utility Methods
+#     #
+#     # CGI escapes +text+
+#
+#     def convert_string text
+#       CGI.escapeHTML text
+#     end
+#
+#   An empty category will place the item in the default category:
+#
+#     # :category:
+#     #
+#     # This method is in the default category
+#
+#     def some_method
+#       # ...
+#     end
+#
+#   Unlike the :section: directive, :category: is not sticky.  The category
+#   only applies to the item immediately following the comment.
+#
+#   Use the :section: directive to provide introductory text for a section of
+#   documentation.
+#
+# [+:section:+ _title_]
+#   Provides section introductory text in RDoc output.  The title following
+#   +:section:+ is used as the section name and the remainder of the comment
+#   containing the section is used as introductory text.  A section's comment
+#   block must be separated from following comment blocks.  Use an empty title
+#   to switch to the default section.
+#
+#   The :section: directive is sticky, so subsequent methods, aliases,
+#   attributes, and classes will be contained in this section until the
+#   section is changed.  The :category: directive will override the :section:
+#   directive.
+#
+#   A :section: comment block may have one or more lines before the :section:
+#   directive.  These will be removed, and any identical lines at the end of
+#   the block are also removed.  This allows you to add visual cues to the
+#   section.
+#
+#   Example:
+#
+#     # ----------------------------------------
+#     # :section: My Section
+#     # This is the section that I wrote.
+#     # See it glisten in the noon-day sun.
+#     # ----------------------------------------
+#
+#     ##
+#     # Comment for some_method
+#
+#     def some_method
+#       # ...
+#     end
+#
+# === Other directives
+#
+# [+:markup:+ _type_]
+#   Overrides the default markup type for this comment with the specified
+#   markup type.  For Ruby files, if the first comment contains this directive
+#   it is applied automatically to all comments in the file.
+#
+#   Unless you are converting between markup formats you should use a
+#   <code>.rdoc_options</code> file to specify the default documentation
+#   format for your entire project.  See RDoc::Options@Saved+Options for
+#   instructions.
+#
+#   At the top of a file the +:markup:+ directive applies to the entire file:
+#
+#     # coding: UTF-8
+#     # :markup: TomDoc
+#
+#     # TomDoc comment here ...
+#
+#     class MyClass
+#       # ...
+#
+#   For just one comment:
+#
+#       # ...
+#     end
+#
+#     # :markup: RDoc
+#     #
+#     # This is a comment in RDoc markup format ...
+#
+#     def some_method
+#       # ...
+#
+#   See Markup@CONTRIBUTING for instructions on adding a new markup format.
+#
+# [+:include:+ _filename_]
+#   Include the contents of the named file at this point. This directive
+#   must appear alone on one line, possibly preceded by spaces. In this
+#   position, it can be escaped with a \ in front of the first colon.
+#
+#   The file will be searched for in the directories listed by the +--include+
+#   option, or in the current directory by default.  The contents of the file
+#   will be shifted to have the same indentation as the ':' at the start of
+#   the +:include:+ directive.
+#
+# [+:title:+ _text_]
+#   Sets the title for the document.  Equivalent to the <tt>--title</tt>
+#   command line parameter.  (The command line parameter overrides any :title:
+#   directive in the source).
+#
+# [+:main:+ _name_]
+#   Equivalent to the <tt>--main</tt> command line parameter.

+# Test case for creating new RDoc::Markup formatters.  See
+# test/test_rdoc_markup_to_*.rb for examples.
+#
+# This test case adds a variety of tests to your subclass when
+# #add_visitor_tests is called.  Most tests set up a scenario then call a
+# method you will provide to perform the assertion on the output.
+#
+# Your subclass must instantiate a visitor and assign it to <tt>@to</tt>.
+#
+# For example, test_accept_blank_line sets up a RDoc::Markup::BlockLine then
+# calls accept_blank_line on your visitor.  You are responsible for asserting
+# that the output is correct.
+#
+# Example:
+#
+#  class TestRDocMarkupToNewFormat < RDoc::Markup::FormatterTestCase
+#
+#    add_visitor_tests
+#
+#    def setup
+#      super
+#
+#      @to = RDoc::Markup::ToNewFormat.new
+#    end
+#
+#    def accept_blank_line
+#      assert_equal :junk, @to.res.join
+#    end

+# The parser tokenizes an input string then parses the tokens into a Document.
+# Documents can be converted into output formats by writing a visitor like
+# RDoc::Markup::ToHTML.
+#
+# The parser only handles the block-level constructs Paragraph, List,
+# ListItem, Heading, Verbatim, BlankLine and Rule.  Inline markup such as
+# <tt>\+blah\+</tt> is handled separately by RDoc::Markup::AttributeManager.
+#
+# To see what markup the Parser implements read RDoc.  To see how to use
+# RDoc markup to format text in your program read RDoc::Markup.

+# RDoc::Options handles the parsing and storage of options
+#
+# == Saved Options
+#
+# You can save some options like the markup format in the
+# <tt>.rdoc_options</tt> file in your gem.  The easiest way to do this is:
+#
+#   rdoc --markup tomdoc --write-options
+#
+# Which will automatically create the file and fill it with the options you
+# specified.
+#
+# The following options will not be saved since they interfere with the user's
+# preferences or with the normal operation of RDoc:
+#
+# * +--coverage-report+
+# * +--dry-run+
+# * +--encoding+
+# * +--force-update+
+# * +--format+
+# * +--pipe+
+# * +--quiet+
+# * +--template+
+# * +--verbose+
+#
+# == Custom Options
+#
+# Generators can hook into RDoc::Options to add generator-specific command
+# line options.
+#
+# When <tt>--format</tt> is encountered in ARGV, RDoc calls ::setup_options on
+# the generator class to add extra options to the option parser.  Options for
+# custom generators must occur after <tt>--format</tt>.  <tt>rdoc --help</tt>
+# will list options for all installed generators.
+#
+# Example:
+#
+#   class RDoc::Generator::Spellcheck
+#     RDoc::RDoc.add_generator self
+#
+#     def self.setup_options rdoc_options
+#       op = rdoc_options.option_parser
+#
+#       op.on('--spell-dictionary DICTIONARY',
+#             RDoc::Options::Path) do |dictionary|
+#         rdoc_options.spell_dictionary = dictionary
+#       end
+#     end
+#   end
+#
+# Of course, RDoc::Options does not respond to +spell_dictionary+ by default
+# so you will need to add it:
+#
+#   class RDoc::Options
+#
+#     ##
+#     # The spell dictionary used by the spell-checking plugin.
+#
+#     attr_accessor :spell_dictionary

+# == Option Validators
+#
+# OptionParser validators will validate and cast user input values.  In
+# addition to the validators that ship with OptionParser (String, Integer,
+# Float, TrueClass, FalseClass, Array, Regexp, Date, Time, URI, etc.),
+# RDoc::Options adds Path, PathArray and Template.

+Usage: #{opt.program_name} [options] [names...]
+
+  Files are parsed, and the information they contain collected, before any
+  output is produced. This allows cross references between all files to be
+  resolved. If a name is a directory, it is traversed. If no names are
+  specified, all Ruby files in the current directory (and subdirectories) are
+  processed.
+
+  How RDoc generates output depends on the output formatter being used, and on
+  the options you give.
+
+  Options can be specified via the RDOCOPT environment variable, which
+  functions similar to the RUBYOPT environment variable for ruby.
+
+    $ export RDOCOPT="--show-hash"
+
+  will make rdoc show hashes in method links by default.  Command-line options
+  always will override those in RDOCOPT.
+
+  Available formatters:

+#{generator_descriptions}

+# The parser extracts the arguments from the method definition.  You can
+# override this with a custom argument definition using the :args: directive:
+#
+#   ##
+#   # This method tries over and over until it is tired
+#
+#   def go_go_go(thing_to_try, tries = 10) # :args: thing_to_try
+#     puts thing_to_try
+#     go_go_go thing_to_try, tries - 1
+#   end
+#
+# If you have a more-complex set of overrides you can use the :call-seq:
+# directive:
+#++
+#
+# The parser extracts the arguments from the method definition.  You can
+# override this with a custom argument definition using the :call-seq:
+# directive:
+#
+#   ##
+#   # This method can be called with a range or an offset and length
+#   #
+#   # :call-seq:
+#   #   my_method(Range)
+#   #   my_method(offset, length)
+#
+#   def my_method(*args)
+#   end
+#
+# The parser extracts +yield+ expressions from method bodies to gather the
+# yielded argument names.  If your method manually calls a block instead of
+# yielding or you want to override the discovered argument names use
+# the :yields: directive:
+#
+#   ##
+#   # My method is awesome
+#
+#   def my_method(&block) # :yields: happy, times
+#     block.call 1, 2
+#   end
+#
+# == Metaprogrammed Methods
+#
+# To pick up a metaprogrammed method, the parser looks for a comment starting
+# with '##' before an identifier:
+#
+#   ##
+#   # This is a meta-programmed method!
+#
+#   add_my_method :meta_method, :arg1, :arg2
+#
+# The parser looks at the token after the identifier to determine the name, in
+# this example, :meta_method.  If a name cannot be found, a warning is printed
+# and 'unknown is used.
+#
+# You can force the name of a method using the :method: directive:
+#
+#   ##
+#   # :method: some_method!
+#
+# By default, meta-methods are instance methods.  To indicate that a method is
+# a singleton method instead use the :singleton-method: directive:
+#
+#   ##
+#   # :singleton-method:
+#
+# You can also use the :singleton-method: directive with a name:
+#
+#   ##
+#   # :singleton-method: some_method!
+#
+# You can define arguments for metaprogrammed methods via either the
+# :call-seq:, :arg: or :args: directives.
+#
+# Additionally you can mark a method as an attribute by
+# using :attr:, :attr_reader:, :attr_writer: or :attr_accessor:.  Just like
+# for :method:, the name is optional.
+#
+#   ##
+#   # :attr_reader: my_attr_name
+#
+# == Hidden methods and attributes
+#
+# You can provide documentation for methods that don't appear using
+# the :method:, :singleton-method: and :attr: directives:
+#
+#   ##
+#   # :attr_writer: ghost_writer
+#   # There is an attribute here, but you can't see it!
+#
+#   ##
+#   # :method: ghost_method
+#   # There is a method here, but you can't see it!
+#
+#   ##
+#   # this is a comment for a regular method
+#
+#   def regular_method() end
+#
+# Note that by default, the :method: directive will be ignored if there is a
+# standard rdocable item following it.

+# RDoc::Task creates the following rake tasks to generate and clean up RDoc
+# output:
+#
+# [rdoc]
+#   Main task for this RDoc task.
+#
+# [clobber_rdoc]
+#   Delete all the rdoc files.  This target is automatically added to the main
+#   clobber target.
+#
+# [rerdoc]
+#   Rebuild the rdoc files from scratch, even if they are not out of date.
+#
+# Simple Example:
+#
+#   require 'rdoc/task'
+#
+#   RDoc::Task.new do |rdoc|
+#     rdoc.main = "README.rdoc"
+#     rdoc.rdoc_files.include("README.rdoc", "lib/**/*.rb")
+#   end
+#
+# The +rdoc+ object passed to the block is an RDoc::Task object. See the
+# attributes list for the RDoc::Task class for available customization options.
+#
+# == Specifying different task names
+#
+# You may wish to give the task a different name, such as if you are
+# generating two sets of documentation.  For instance, if you want to have a
+# development set of documentation including private methods:
+#
+#   require 'rdoc/task'
+#
+#   RDoc::Task.new :rdoc_dev do |rdoc|
+#     rdoc.main = "README.doc"
+#     rdoc.rdoc_files.include("README.rdoc", "lib/**/*.rb")
+#     rdoc.options << "--all"
+#   end
+#
+# The tasks would then be named :<em>rdoc_dev</em>,
+# :clobber_<em>rdoc_dev</em>, and :re<em>rdoc_dev</em>.
+#
+# If you wish to have completely different task names, then pass a Hash as
+# first argument. With the <tt>:rdoc</tt>, <tt>:clobber_rdoc</tt> and
+# <tt>:rerdoc</tt> options, you can customize the task names to your liking.
+#
+# For example:
+#
+#   require 'rdoc/task'
+#
+#   RDoc::Task.new(:rdoc => "rdoc", :clobber_rdoc => "rdoc:clean",
+#                  :rerdoc => "rdoc:force")
+#
+# This will create the tasks <tt>:rdoc</tt>, <tt>:rdoc:clean</tt> and
+# <tt>:rdoc:force</tt>.
