Ok, a little guidance please.  As I understand it if I import setuptools 
into my app setup.py and I subclass my install from 
setuptools.command.install, then I can also use the option 
'--single-version-externally-managed' to make the install behave like 
the distutils style install.  Is that correct?
If this is true then what I would like to do is to force this option on 
in the code.  How can I do that?  I know I can probably put it into 
setup.cfg but I just think it would be better hardwired into the code.
