I will plug in my own work on plac: http://pypi.python.org/pypi/plac
Your problem would be solved as follows:

import plac

@plac.annotations(test=('a flag', 'flag', 't'))
def main(test, *ignore):
    print test, ignore

if __name__ == '__main__':
    plac.call(main, ["-t","--ignoreme_and_dont_fail"])
