+Python-Markdown Extra Extension
+===============================
+
+A compilation of various Python-Markdown extensions that imitates
+[PHP Markdown Extra](http://michelf.com/projects/php-markdown/extra/).
+
+Note that each of the individual extensions still need to be available
+on your PYTHONPATH. This extension simply wraps them all up as a 
+convenience so that only one extension needs to be listed when
+initiating Markdown. See the documentation for each individual
+extension for specifics about that extension.
+
+In the event that one or more of the supported extensions are not 
+available for import, Markdown will issue a warning and simply continue 
+without that extension. 
+
+There may be additional extensions that are distributed with 
+Python-Markdown that are not included here in Extra. Those extensions
+are not part of PHP Markdown Extra, and therefore, not part of
+Python-Markdown Extra. If you really would like Extra to include
+additional extensions, we suggest creating your own clone of Extra
+under a differant name. You could also edit the `extensions` global 
+variable defined below, but be aware that such changes may be lost 
+when you upgrade to any future version of Python-Markdown.
