LinCVS for Mac

From CrossVC:

LinCVS is a graphical Interface for the cvs client commandline tool on the Unix, Windows and Mac OS X platform. It allows ato load modules from a server (checkout), create modules on the server (import), as well as checking the state of directories and individual files or updating them. Basic operations like add, remove and commit are supported as matter of course, just like showing the actual differences between the server version and the local sandbox, graphical display of the version tree, and manifoldy graphical support of project maintenance. All actions are logged on the cvs server (configurable via history), and are therewith comprehensible.

To keep LinCVS independant of the cvs version, LinCVS uses the local but separately installed cvs and therefore always should work with the latest version.
