Background
----------

I've been looking for a tool that would visually "replay" the programmer's work, like a 24h/24 screencast of their editor, but played at an accelerated speed. The aim is to :
1. See the evolution of the whole project.
2. See the evolution of the contents of a single file.

[Gource](http://code.google.com/p/gource/) provides a soluion for aim #1, and Apple's "time machine" (Mac OS X) seems to provide something somehow related. But both seem to work with a granularity of files & folders, which is too big for aim #2 (I want to see the acual code being modified).

So I created a short script that allows you to navigate through the different versions of a single file.
