In Linux (maybe in Windows) you can tell an application to stop
processing args by using '--'. Given this code:
import sys
from optparse import OptionParser
op = OptionParser()
op.add_option('--a', dest='a', action='store_true', default=False)
op.add_option('--b', dest='b', action='store_true', default=False)
opts, args = op.parse_args(sys.argv)
print 'opts:', opts
print 'args:', args
Here is an example use:
eee0:~% python junk.py --a -- --c
{'a': True, 'b': False}
['junk.py', '--c']
