Perforce

Perforce, the Fast Software Configuration Management (SCM) System, provides powerful version control and workspace management with a unique branching model. Perforce provides software developers with fast and reliable SCM to manage source, document and Web content. The client/server architecture scales to hundreds of users and millions of codelines. Perforce works well even on limited bandwidth networks. The server's repository sits on a central host; client workspaces can be anywhere on the network -- around the office or the world.
