having take a quick look at DummySR, i have a question.

    if __name__ == '__main__':
        SRCommand.run(DummySR, DRIVER_INFO)
    else:
        SR.registerSR(DummySR)

i understand that the SRCommnad.run part is for XMLRPC with
sm_type Executable.  what is the SR.registerSR part for?
i couldn't find any python code which imports this file.
