How do you setup subversion?

I think what you're talking about would involve using SVN externals. Google it and there are some links to help get you up and running with something like that. I've never done it myself though, so I can't vouch for the process. Personally, I like doing the CI updates manually because it gives me more control over when I update (or if I update).
