Support for inline text styling using custom roles.
Support for inline text styling using custom roles.

For example, suppose you want the word "red" to be shown red, you would define a
redtext style and use this:
  
  
.. role:: redtext

This is :redtext:`red`.

The bad news is that to define custom styles right now you need to edit styles.py, 
but don't worry, that's getting fixed very very soon.
