      The Pygments reStructuredText directive
      ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  
      This fragment is a Docutils_ 0.5 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.
