Fwd: [Question #189464]: How to run __main__ programs inside python-mode?

I'm probably missing something obvious, but what's the best way to use 
python-mode to run/debug python scripts that are designed to be run from 
the command line? In particular, the problem I face is that while 
__main__ is set fine, if my code tries to access sys.argv, it gets 
information that is not very useful, e.g.,

In [5]: sys.argv
Out[5]: ['/Library/Frameworks/EPD64.framework/Versions/7.2/bin/ipython', 
'-i']

I could always write a main() function, set up my own argument list, and 
then call main(myargs), or something similar, but this isn't so 
convenient when all I want to do is run someone else's sample code.

How do others deal with this? Is there a facility in python-mode (or 
should there be) to pass a user-defined sys.argv to scripts run by 
pressing C-c C-c?
