I'm interested in the Backtrack 4 "approved" method for dealing with sources. In a traditional Ubuntu distro, I would add a deb-src, and use build-deps to get dependencies. I haven't found any reference to a source URI for my BT4 R1 sources.list - what am I missing?

If there's no deb-src "source" URI, I'd like to know if there are plans for it...
