We have just released a new app to the market called GitPull, v1.0.0!
This app will download any Git repository to some place inside your $XP_HOME folder, with just some simple configuration. It is a handy feature if you want to keep version control on your configuration or set up Continuous Delivery environment on a live site. It may also be handy in development and testing.
