pactree gives a graphical picture of all the dependencies. It's not used
in the current code, since I refactored it to drop a lot of
dependencies. But, as a tool it will still tell you what depends on what.

Not sure I understand here to be honest.

Oh yeah, that's funny.

The no-deps version should work fine all by itself. Indeed, this used to
be the only form of Emacs distribution for windows. It just won't do
some things.

Yes, I know.
