Well, as I am writing stuff on my home computer, I need to step into the modern world and get into a DSCM. I put out an email to the rspec group to get people's opinions on what I should use. David Chelimsky likes mercurial and git, then bazaar came up. Git doesn't run on windows, so it is out. Mercurial and Bazaar are written in Python, so they'll run on my system. After reading this comparison of Mercurial and Bazaar (yeah, I know, it was written by the Bazaar people), I decided to give Bazaar a chance first.
If I find anything interesting, I'll post. I'm going to give Bazaar two weeks of use, then Mercurial two weeks of use.
