I almost did that myself.

Yes, I knew about that. This is the API that an IDE and/or dependency
manager (i.e. - leiningen) needs to use to do #1 and #2. It is not,
however, a replacement for an IDE or dependency manager actually doing
those things.

Cool. This one is my bad - I had gotten the idea that it wouldn't find
dependencies, and had always filled them in by hand. And I had figured
this would be the hard one of the three to do.
