hum, it's a feature that has been of use to some people.

sure, but this is what setuptools creates, it's not what
py/bin/py.test specifies and what gets installed with a
distutils install.

i guess i could and probably also the others.  I'll think about it. 

If others like to chime in here, please do so. 

I can also imagine to just use a normal distutils setup.py 
for 0.9.2 based on what you did.  I recently i even had someone
not wanting to use setuptools based installs (for a different
project).  Btw, I actually assumed that python 2.5 came with setuptools 
but that is not the case, has just been discussed at some point, right?
