I think PJE was referring to something like this:
$ cat foo.egg-info/requires.txt
which is defined in setup.py like this:
$ cat setup.py
Currently you have to manually specify, say, "easy_install
foo[platform-eq-win32,python-lt-26]" if you are installing on Windows
Python 2.5. But with a little modification, this can be made automatic.
Zope packages makes use of this kind of 'extras' feature a lot .. eg:
"easy_install foo[tests]" would also install nose.
Setuptools already has this feature. I suggest we make this a standard of
doing things and extend the extras syntax to implement conditional
