The Perforce Software Configuration Management System features comprehensive SCM capabilities built around a scalable client/server architecture. Users can access the Perforce Server through a range of Perforce client software. Perforce can be deployed quickly and easily, and requires minimal administration even for large or distributed sites.

There is an old set of Perforce actions (Perforce Sync and Perforce Command) which are now deprecated, but are still available for backwards compatibility. We recommend that you disable or not install the old Perforce package if you don't need these actions.
