I've been reacquainting myself with classic Mac OS programming (e.g. the Toolbox, MacsBug, THINK Pascal/C, etc.) and became curious how software engineering best practices were ...practiced... using the platform's tools of the day.
Specifically, I've been looking into source code management: what tools did classic Mac OS programmers use for source control?
My beard is grey enough to have personally worked with eight or nine different SCM tools, but all of them have been for DOS/Windows, *NIX, and "big(-ish) iron" environments. My Google-Fu is apparently weak in this area, as the only thing I've been able to find being "discussed" "widely" is MPW's Projector and SourceServer tools. Was that the standard? Were there other options in common use?
