[Distutils] licenses for ez_setup and virtual_python

[Chris McDonough]

We'd like to distribute ez_setup.py and virtual_python.py with a good  
number of our packages.  I suspect ez_setup.py is licensed under the  
same dual ZPL/PSF license as is setuptools.  I'm not sure how  
virtual_python.py is licensed (I got it from From http:// 
peak.telecommunity.com/dist/virtual-python.py).

I'd like to do the right thing for licensing and attribution.  What  
would the authors of these packages like to see as far as attribution  
and licensing artifacts in packages that include them?
