I've not really spent any time with RCS lately but I can tell you there is a "branding" method folks use in RCS to specify a release. PVCS went a step further with this concept, and introduced CM, or configuration management as an add-on product. This essentially allows you to build an alpha, then beta, then c-release. You can do this with essentially all the products mentioned so far, however the CM component of PVCS is quite comprehensive, and addresses specific releases where a company is dealing with several releases at one time. I'm sure Informix uses something like this. ( And I've seen RCS comments in some of the Informix objects. ( .o ) ) I'm not endorsing PVCS per se, but the methodology <IS> available either through commercial products or RCS. This was one of the key selling points of RCS over SCCS, however, as I say, I've forgotten specifically how this is accomplished. You can find a wealth of information in the O'reilly book on Applying RCS and SCCS. The authors favor RCS, but get the book, and form your own opinion.
