PRCS: The Project Revision Control System

PRCS is an attempt to provide a version-control system for collections of les with a simple operational model, a clean user interface, and high performance. PRCS is characterized by the use of project description les to input most commands, instead of a point-and-click or a line-oriented interface. It employs optimistic concurrency control and encourages operations on the entire project rather than individual les. Although its current implementation uses RCS in the back-end, the interface completely hides its presence. PRCS is free. This paper describes the advantages and disadvantages of our approach, and discusses implementation issues.
