from optparse import OptionParser

usage = \
"""%prog [args]

parser = OptionParser(usage=usage)
parser.add_option("-k", "--keywords", dest="keywords", help="keywords to search")
parser.add_option("-n", "--number", dest="number_threads", type="int", help="number of threads", default=10)
parser.add_option("-s", "--skip", dest="skip", action="store_true", help="whether skip snonymous account or not", default=False)
(options, args) = parser.parse_args()
