Faking out __name__ == __main__

[Ed Leafe]

	I'm working on creating a generic runtime engine for the Dabo 
framework. Right now I'm focusing on Windows, since many of our 
potential users are running on that platform. I've got py2exe and Inno 
Setup running, so all that is well and good.

	My question concerns the ability to generically run scripts as if they 
were being run on an installed copy of Python. Many scripts have the 
following structure:

if __name__ == "__main__":
	method1()
	method2()
	...etc.
	methodN()

When such a script is run with the command 'python myscript.py', the 
various methods are called. However, when run with 'daborun 
myscript.py', (daborun is the name of the py2exe file), nothing gets 
executed, since when the call to 'myscript.py' is made, __name__ is now 
set to 'myscript', and the statements after the 'if __name__' test are 
never executed.

	I have several ways of working around this, such as requiring that all 
code after the 'if __name__' test be moved into a 'main()' method, and 
having daborun call the main() method, but it would *so* much cooler to 
be able to somehow fake out the value of __name__ when the call is made 
to the script. Is this something that might be possible, or is it so 
fundamental to the internals of Python that it can't be messed with?
