Yes that's not so nice, many projects write clearly the dependencies in 
the README file,
but that's annoying because it might get outdated.

And it's also sad that it's not automatically fetched from setuptools, 
because it's just

python setup.py egg-info && cat package.egg-info/requirements.txt

to actually extract them.
Should I file a bug maybe or is completely not feasible?
