[Python-3000] PEP to change how the main module is delineated

[Neal Norwitz]

Can you add refs to all the PEPs?

Will this go into 2.6 also?  If so, you should send to python-dev too.
If this is accepted, can you update the 2.6 PEP 361.

What happens when no file is passed in (ie, interactive) or when -c is used?
Will sys.main be set?  If so, to what?
