I foresee problems with using constants from the python runtime as
they currently stand. Only for the simple reason that the existing
'constants' were good 5 years ago. But won't be good - next year.

For example, 'win32' refers to a specific windows because windows 
can now be 64 bit. 

Does win32 mean win64? It does now - but it shouldn't.

I propose windows and 32 and 64 as further qualifiers. So for example,
'windows' or 'windows-32' or 'windows-64'. Not to mention 'windows-xp-32' 
and 'windows-xp-64' and 'windows-ce'.

Maybe windows-128 is around the corner - who knows..

I respect those sys python constants.. but they are too unspecific
to be used here.

And for linux, what is 'linux2' ? It should just be linux.. to
make it less confusing.

Anyway, I'm coding this all up now into an example.

So far I have in my table..

standard_platform_bits = ('windows','linux','mac',

I think we need new constants for package installation. It
will be less confusing. Whichever way we go.
