I decided to create a fork of rouge as rouge lacks a HTML formatter with the required options such as wrapping a line with <span> tags. Furthermore I was not really convinced about the clarity of rouge's source code. Rugments 1.0.0beta3 for now only includes some basic linting and a new HTML formatter. Everything else should behave the same.
