Subversion is a bit of a learning curve for most people (except those who use CVS probably!), but is a very popular and capable Version Control System which happens to be opensource. FinalBuilder has a whole bunch of built in actions for Subversion: Add, Checkout, Cleanup, Commit, Copy, Export, Import, Mkdir, Revert, Status, Switch, Update, and a Generic action so you can use other Subversion functions which don't have a specific FB action.
