-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 
     and  as well).
-
-For more information about Markdown's syntax, see:
-

-Bugs

-
-To file bug reports please send email to:
-
-
-
-Please include with your report: (1) the example input; (2) the output you
-expected; (3) the output Markdown actually produced.
