[Tutor] Main program confusion

[Hazlett, Les]

Hello,

 

I am trying to understand some sample code that includes the following
for a main program:

 

def runTest(frame, nb, log):

    win = TestPanel(nb, log)

    return win

 

if __name__ == '__main__':

    import sys,os

    import run

    run.main(['', os.path.basename(sys.argv[0])] + sys.argv[1:])

 

I understand that win is an object of the class TestPanel.  The class
code for TestPanel preceded

the code which I copied above.  The object win clearly is instantiated.
I understand how the 

if__name__=='__main__' only runs when this program file is executed.

But, I can't find any reference to a module run and I don't see how the
"run.main([" line casues 

the "runTest(" function to run.

 

What am I missing?

 

Thanks for any help.
