I should do that. I used to use RCS for everything, and my recollection is that after I read the man page once or twice, I knew almost everything I needed to know. SCCS had a bit more of a learning curve. As for git, I almost always have to read not just the man page, but actually look on-line for clarification about almost anything. I think of git as the C++ of version control systems. (Not sure how far that analogy goes--I don't know what programming language I would compare RCS to, Pascal?)
