o nuke another big chunk of the old code, looking for available versions is used internally and once all the methods are shed we'll supply a pure metadata resolution for clients, like IDEs, that need to nicely show versions. we'll also provide a graph too so people aren't going to have to do all the extra crap to get decent information.
