CSSC is the GNU project's replacement for the traditional Unix SCCS suite. It aims for full compatibility (including precise nuances of behaviour, support for all command-line options, and in most cases bug-for-bug compatibility) and comes with an extensive automated test suite. If you currently use SCCS for version control, you should be able to just drop in CSSC, even if you have a large number of shell scripts which are layered on top of SCCS and depend on it. This will let you to develop on and for GNU/Linux if your source code exists only in an SCCS repository. CSSC also lets you migrate to a more modern version control system.
