A.11. OpenCM

"OpenCM is designed as a secure, high-integrity replacement for CVS. A list of the key features can be found on the features page. While not as `feature rich' as CVS, it supports some useful things that CVS lacks. Briefly, OpenCM provides first-class support for renames and configuration, cryptographic authentication and access control, and first-class branches."
