Description: Piston is a utility that eases vendor branch management. This repository is a complete reimplementation of Piston to provide different backends, depending on the repositories and working copies you pistonize from.
Homepage: http://piston.rubyforge.org/
Clone URL: git://github.com/francois/piston.git
Search Repo: 
Remember the repository's class and URL at the top level in .piston.yml.

I wanted to implement this to not have to guess the repository type again, 
while implementing piston update.
