I'm planning on making a hard push for git on the team I just joined (that isn't using any VCS). This and OP are going in my bookmarks.
I'm genuinely curious how they manage source without any VCS. Is it just a bunch of zip files for old versions? No judgment, nobody is born knowing this stuff, just that I'm surprised to hear this is still out in the wild.
I have seen it as files on a shared drive. I have seen it as files on a sharepoint drive. I have seen it as files inside of an SVN repository.
