version control api

So that's that. After having used the past two months for improving filefield and imagefield, it's about time that I get started with my RCS abstraction project. aclight has been as kind as to publish his work and findings in time with the Summer of Code, so that's a good starting point already. His work on the xcvs scripts (...bootstrapping Drupal, yay) benefits my project a lot, and the issues with password storage are good to know of.

In order to come up with a set of good questions that I'll need to research, I had a first shot on the database schema and the overall idea of how this thing should work. I thought it would be a good idea to see what we want to achieve and what we can rely on, before figuring out how to abstract all the stuff that's supposed to be different among the various revision control systems. Bullet points galore.
