OpenCVS is a BSD-licensed implementation of the popular Unix version control software called Concurrent Versions System. OpenCVS is developed as a part of the OpenBSD project by Jean-Francois Brousseau, Xavier Santolaria, Niall O'Higgins and others.
OpenCVS aims to be as compatible as possible with the GNU CVS implementation without compromising security or source code correctness, and to provide better access control. As of December 2004[update], the project website claims that "OpenCVS [is to be] released soon" and the project shows CVS activity as recent as January 2014. The project is still (occasionally actively) being developed.
