Python – How to Import a Module as __main__

I have a module that has the usual

if __name__ == '__main__':
    do stuff...

idiom.

I'd like to import that from another module, and fool it into running that code. Is there any way of doing this?

I should mention, for reasons I won't go into here, I'm not in a position to change the code in the imported module. I need to somehow modify the import procedure so that it's name is main when imported, perhaps using ihooks or similar.
