R2Doc is an improved generator for RDoc. It provides an improved output template for documentation, but also aims to be more extensible so that template authoring is an easier task with a wider set of options.

Installation
The generator is available as a gem from GitHub. If you haven't already, you'll first need to add GitHub as a gem source:

Then you just install the gem:
