I just did a "remove the alt- functionality" pass, which I'm testing,  
and next I'm adding logic so that if a directory packages/package  
exists for a package, it'll ignore the tarball and use that directly  
instead. (In this case it won't patch it, you'll have to patch it  
yourself.)

This basically means you can supply your own extracted source for a  
package (git repo, mercurial, subversion: I don't care) and it'll just  
use it.

I'm also taking out the "hardlink vs softlink" thing and making it so  
it tries hardlink first, and falls back to softlink if that doesn't  
work. (I.E. not on same filesystem.)
