Base class for creating commandline python scripts using optparse

example

class MyScript(OptionParserScript):
    usage = "Usage: %prog <command> [arguments]"
    options = {
        ('-v','--verbose'): {'help':"Be verbose", 'action': 'store_true', 'default': False},
    }

        import pprint
        pprint.pprint(args)
        pprint.pprint(kwargs)
        return 0


if __name__ == '__main__':
    script = MyScript()
    sys.exit(script())
