CVS
CVS (Concurrent Versions System) was a version control system. The primary utility was cvs(1), a command-line executable.
Compare to Git.

Installation
Some distributions still offer a cvs package. Few offer critical scripts and libraries, like cvsps.
Usage
I can only recommend using cvs to migrate away from CVS.
rsync -av rsync://PROJECT.cvs.sourceforge.net/cvsroot/PROJECT/\* cvs git cvsimport -v -a -k -d $(realpath ./cvs) -C $(realpath ./git) MODULE
Available module names will be the top-level directories under cvs.
