34Python-Markdown Extra Extension
35===============================
36
37A compilation of various Python-Markdown extensions that imitates
38[PHP Markdown Extra](http://michelf.com/projects/php-markdown/extra/).
39
40Note that each of the individual extensions still need to be available
41on your PYTHONPATH. This extension simply wraps them all up as a
42convenience so that only one extension needs to be listed when
43initiating Markdown. See the documentation for each individual
44extension for specifics about that extension.
45
46In the event that one or more of the supported extensions are not
47available for import, Markdown will issue a warning and simply continue
48without that extension.
49
50There may be additional extensions that are distributed with
51Python-Markdown that are not included here in Extra. Those extensions
52are not part of PHP Markdown Extra, and therefore, not part of
53Python-Markdown Extra. If you really would like Extra to include
54additional extensions, we suggest creating your own clone of Extra
55under a differant name. You could also edit the `extensions` global
56variable defined below, but be aware that such changes may be lost
57when you upgrade to any future version of Python-Markdown.
