I used sccs on Sun workstations back in the 1990s. It wasn’t terrible but if you had more than a few team members then chasing people to check their code in for a build was painful and sometimes you’d hit a point where the project wouldn’t compile because of incompatible changes. We switched to PVCS which made it easier to have isolated work spaces, plus a bunch of scripts to build those so developers could effectively emulate feature branches. Merging was a bit painful but at least you could work without holding other people up. I’ve used other tools since but git is damn good compared to those older tools. I do miss being able to embed version strings but in reality tagging is superior if you have disciplined release control.
