I don't like much the syntax of:
if __name__ == '__main__':
Some time ago I have read this PEP:
http://www.python.org/dev/peps/pep-0299/
And why it was refused:
http://mail.python.org/pipermail/pyt...ch/062955.html
I think the name of the standard main function may be just main(), so
there isn't the problem with the import (and *maybe* the problem with
multiple Python versions can be ignored with Python 3.0).
If a module contains the main(), the main() is executed when the module
is run alone. Otherwise you can import the module, with the main()
function managed as a normal function.
