Error running scripts but not in python interactive window.

[Davin-C]

Got the below response when running as a script in the form "python test.py" with one of the examples in the code. However, it works in a python interactive window perfectly. Thought I should flag this and thanks for the lib.

    This probably means that you are not using fork to start your
    child processes and you have forgotten to use the proper idiom
    in the main module:

        if __name__ == '__main__':
            freeze_support()
            ...

    The "freeze_support()" line can be omitted if the program
    is not going to be frozen to produce an executable.

you have to encapsulate your test code in a function and call it from a main

def your_test_code_here():
    ....

if __name__ == '__main__':
            your_test_code_here()
