Comment (by russellm):
If the issue is maintaining source code compatibility with both trunk
(which has the change) and v1.0.X (which doesn't), there is a solution -
check whether --verbosity is available as an option before adding it. The
following code will allow you to maintain a single code base, but support
both branches:
{{{
class Command(BaseCommand):
option_list = BaseCommand.option_list + (
make_option('--blah', action='store_false', dest='blah',
default=True),
)
if '--verbosity' not in [opt.get_opt_string() for opt in
BaseCommand.option_list]:
option_list += make_option('-v','--verbosity', action='store',
dest='verbosity', default='1',
type='choice', choices=['0', '1', '2'],
help='Verbosity level; 0=minimal output, 1=normal output,
2=all output'),
...
}}}
