I forgot that this bit requires making an OptionGroup wrapper.
from optparse import OptionGroup as _OptionGroup
class OptionGroup(_OptionGroup):
def __enter__(self):
return self
def __exit__(self, *exc_info):
self.parser.add_option_group(self)
Also I have been thinking about this and I think the way I did it is
clunkier than necessary. Better would be to do two passes of
optparse--one to figure out what plugins to load, then load their
options into the OptionParser, and parse the options again. This would
require special handling for help and option conflicts, but would be a
better user experience.
