btw,
I just found this in one of my programs (which works but isn't very 
beautiful)

In the library fill under construction I put this main section:
(sb_test.py is the main program, that has a main section and uses the 
library under construction)

if __name__ == '__main__':
    import db_test
    new_globals = {}
    new_globals [ '__name__' ] = '__main__'
    new_globals [ '__file__' ] = 'not really valuable'
    execfile ( 'db_test.py', new_globals )
