             # = RedCloth
             #
             # RedCloth is a Ruby library for converting Textile and/or Markdown
             # into HTML.  You can use either format, intermingled or separately.
             # You can also extend RedCloth to honor your own custom text stylings.
             #
             # RedCloth users are encouraged to use Textile if they are generating
             # HTML and to use Markdown if others will be viewing the plain text.
             #
             # == What is Textile?
             #
             # Textile is a simple formatting style for text
             # documents, loosely based on some HTML conventions.
             #
             # == Sample Textile Text
             #
             #  h2. This is a title
             #
             #  h3. This is a subhead
             #
             #  This is a bit of paragraph.
             #
             #  bq. This is a blockquote.
             #
             # = Writing Textile
             #
             # A Textile document consists of paragraphs.  Paragraphs
             # can be specially formatted by adding a small instruction
             # to the beginning of the paragraph.
             #
             #  h[n].   Header of size [n].
             #  bq.     Blockquote.
             #  #       Numeric list.
             #  *       Bulleted list.
             #
             # == Quick Phrase Modifiers
             #
             # Quick phrase modifiers are also included, to allow formatting
             # of small portions of text within a paragraph.
             #
             #  \_emphasis\_
             #  \_\_italicized\_\_
             #  \*strong\*
             #  \*\*bold\*\*
             #  ??citation??
             #  -deleted text-
             #  +inserted text+
             #  ^superscript^
             #  ~subscript~
             #  @code@
             #  %(classname)span%
             #
             #  ==notextile== (leave text alone)
             #
             # == Links
             #
             # To make a hypertext link, put the link text in "quotation
             # marks" followed immediately by a colon and the URL of the link.
             #
             # Optional: text in (parentheses) following the link text,
             # but before the closing quotation mark, will become a Title
             # attribute for the link, visible as a tool tip when a cursor is above it.
             #
             # Example:
             #
             #  "This is a link (This is a title) ":http://www.textism.com
             #
             # Will become:
             #
             #  <a href="http://www.textism.com" title="This is a title">This is a link</a>
             #
             # == Images
             #
             # To insert an image, put the URL for the image inside exclamation marks.
             #
             # Optional: text that immediately follows the URL in (parentheses) will
             # be used as the Alt text for the image. Images on the web should always
             # have descriptive Alt text for the benefit of readers using non-graphical
             # browsers.
             #
             # Optional: place a colon followed by a URL immediately after the
             # closing ! to make the image into a link.
             #
             # Example:
             #
             #  !http://www.textism.com/common/textist.gif(Textist)!
             #
             # Will become:
             #
             #  <img src="http://www.textism.com/common/textist.gif" alt="Textist" />
             #
             # With a link:
             #
             #  !/common/textist.gif(Textist)!:http://textism.com
             #
             # Will become:
             #
             #  <a href="http://textism.com"><img src="/common/textist.gif" alt="Textist" /></a>
             #
             # == Defining Acronyms
             #
             # HTML allows authors to define acronyms via the tag. The definition appears as a
             # tool tip when a cursor hovers over the acronym. A crucial aid to clear writing,
             # this should be used at least once for each acronym in documents where they appear.
             #
             # To quickly define an acronym in Textile, place the full text in (parentheses)
             # immediately following the acronym.
             #
             # Example:
             #
             #  ACLU(American Civil Liberties Union)
             #
             # Will become:
             #
             #  <acronym title="American Civil Liberties Union">ACLU</acronym>
             #
             # == Adding Tables
             #
             # In Textile, simple tables can be added by seperating each column by
             # a pipe.
             #
             #     |a|simple|table|row|
             #     |And|Another|table|row|
             #
             # Attributes are defined by style definitions in parentheses.
             #
             #     table(border:1px solid black).
             #     (background:#ddd;color:red). |{}| | | |
             #
             # == Using RedCloth
             #
             # RedCloth is simply an extension of the String class, which can handle
             # Textile formatting.  Use it like a String and output HTML with its
             # RedCloth#to_html method.
             #
             #  doc = RedCloth.new "
             #
             #  h2. Test document
             #
             #  Just a simple test."
             #
             #  puts doc.to_html
             #
             # By default, RedCloth uses both Textile and Markdown formatting, with
             # Textile formatting taking precedence.  If you want to turn off Markdown
             # formatting, to boost speed and limit the processor:
             #
             #  class RedCloth::Textile.new( str )
             class RedCloth3 < String
                 VERSION = '3.0.4'
                 DEFAULT_RULES = [:textile, :markdown]
                 #
                 # Two accessor for setting security restrictions.
                 #
                 # This is a nice thing if you're using RedCloth for
                 # formatting in public places (e.g. Wikis) where you
                 # don't want users to abuse HTML for bad things.
                 #
                 # If +:filter_html+ is set, HTML which wasn't
                 # created by the Textile processor will be escaped.
                 #
                 # If +:filter_styles+ is set, it will also disable
                 # the style markup specifier. ('{color: red}')
                 #
                 attr_accessor :filter_html, :filter_styles
                 #
                 # Accessor for toggling hard breaks.
                 #
                 # If +:hard_breaks+ is set, single newlines will
                 # be converted to HTML break tags.  This is the
                 # default behavior for traditional RedCloth.
                 #
                 attr_accessor :hard_breaks
                 # Accessor for toggling lite mode.
                 #
                 # In lite mode, block-level rules are ignored.  This means
                 # that tables, paragraphs, lists, and such aren't available.
                 # Only the inline markup for bold, italics, entities and so on.
                 #
                 #   r = RedCloth.new( "And then? She *fell*!", [:lite_mode] )
                 #   r.to_html
                 #   #=> "And then? She <strong>fell</strong>!"
                 #
                 attr_accessor :lite_mode
                 #
                 # Accessor for toggling span caps.
                 #
                 # Textile places `span' tags around capitalized
                 # words by default, but this wreaks havoc on Wikis.
