+"""
+ The Pygments reStructuredText directive
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+ This fragment is a Docutils_ 0.4 directive that renders source code
+ (to HTML only, currently) via Pygments.
+
+ To use it, adjust the options below and copy the code into a module
+ that you import on initialization. The code then automatically
+ registers a ``sourcecode`` directive that you can use instead of
+ normal code blocks like this::
+
+ .. sourcecode:: python
+
+ My code goes here.
+
+ If you want to have different code styles, e.g. one with line numbers
+ and one without, add formatters with their names in the VARIANTS dict
+ below. You can invoke them instead of the DEFAULT one by using a
+ directive option::
+
+ .. sourcecode:: python
+ :linenos:
+
+ My code goes here.
+
+ Look at the `directive documentation`_ to get all the gory details.
+
