MPW: Well, I can't really give it a review in spite of my efforts.

This was back when I was learning programming in high school, and the only really free C++ compiler to be had was Macintosh Programming Workbench, which I kept on a zip disk and popped into whichever Performa was available in the lab.

MPW came with dozens of tools (none of which were resedit, that was a separate download), and one of them was a version control utility. It popped open a small window with a single line of text, and you were to drag and drop your projects or files onto it. It had no documentation that I was ever able to discover, unusual considering everything else seemed to have great docs, and so I never quite worked out how to use it.

That was my first brush with VC, and the last one for a good long while. Now I use git for everything.
