This is a tool written with node.js to keep a directory up to date and checked out with the current versions on the remote server.
You must create a config.json with at least a repo which points to a git repo, and a title which is used in the display. You may also change the output directory with output and the repo working area with working.
At that point, if you grunt it should clone the remote repo and start setting up a folder for each brach and tag.
If you create a file called build-command.sh it will be executed in the directory for each branch and tag after it is updated.
A cron.sh is provided to run grunt cron and surround it in a .lock check.
