##
# 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
