I owe my career as a software developer to the Amiga. I might have learned the basics of programming on the Apple II+ and Commodore 64 - but on my Amiga I learned skills I've applied to my whole career. Recently I've been having great fun working my way through stacks of old floppies and finding half-finished projects, source code, graphics resources and generally weird stuff I produced almost 30 years ago! Now I'm trying to get everything organized and I started wondering what kinds of version control systems are available for the classic 68k Amiga.
My first inclination was to try and find a backport of Git, but my google searches came up empty. I remember vaguely there was a program called RCS (I think) that acted as a revision control system. What are people using for version control on a classic Amiga?
