+
+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.
