Git

Total control

Git is the version control system written by Linus Torvalds, creator of Linux.

Git allows developers to work with ease on multiple versions of a project without being connected to the net. It allows deployments of websites to be managed in a way that will not hinder feature development while deployment issues are being fixed.

Its bisect feature is awesome for discovering when a bug was introduced.

On top of all this, it's lightning quick. If you've ever waited for a Subversion checkout of a Rails project that contains a frozen version of Rails, you'll appreciate this.

Git busy

If you haven't already, git on board. Apologies.
