I'm a bit confused myself... PEP-345 says it "describes a mechanism
for adding metadata to Python packages", but I think they really mean
"distributions" (the things available at the PyPI).
Also, it looks like pep345 describes what fields can go into a
PKG-INFO file, but not how you get them in there. AFAIK, I'm not
supposed to write my own PKG-INFO file -- setup.py does it for me.
What I'm really asking about here is, what args go in the `setup()`
call in the `setup.py` file?
If my FooBar-0.1.0 distribution depends upon packages and modules in
CoolStuff-2.0.0 and ReallyNeatStuff-1.5.5, what's the current best way
to say so, and what's going to be the standard going forward?
