Mercury is a git repository setup module. It's Sinatra app that wait for queries to create git repositories, setup the authorized_keys file, return the status of a specific repository and say if it's alive or not.
Mercury doesn't have much brain and all the data about repository creation (paths, names, etc...) must come from another app.
It also setup a post receive hook to update repository status on the main web interface.
