+-
+-PHP Markdown Extra
+-==================
+-
+-Description
+------------
+-
+-This is a PHP port of the original Markdown formatter written in Perl
+-by John Gruber. This special "Extra" version of PHP Markdown features
+-further enhancements to the syntax for making additional constructs
+-such as tables and definition list.
+-
+-Markdown is a text-to-HTML filter; it translates an easy-to-read /
+-easy-to-write structured text format into HTML. Markdown's text format
+-is most similar to that of plain text email, and supports features such
+-as headers, *emphasis*, code blocks, blockquotes, and links.
+-
+-Markdown's syntax is designed not as a generic markup language, but
+-specifically to serve as a front-end to (X)HTML. You can use span-level
+-HTML tags anywhere in a Markdown document, and you can use block level
+-HTML tags (like <div> and <table> as well).
+-
+-For more information about Markdown's syntax, see:
+-
+-<http://daringfireball.net/projects/markdown/>
+-
+-
+-Bugs
+-----
+-
+-To file bug reports please send email to:
+-
+-<michel.fortin@michelf.com>
+-
+-Please include with your report: (1) the example input; (2) the output you
+-expected; (3) the output Markdown actually produced.
