I am not submitting here, I just want to discuss it first.
1. what do you think of this syntax I invented:
--option "list of items"
I don't like it, but not sure how else to do it.
2. should I leave in --debug? I really meant it for debugging, but I can see
it
being handy to debug the "list of items" and such.
Why does the current code has 'json' listed in 2 places:
make_option('--format', default='json'
options.get('format', 'json')
note: "default - Deprecated; use parser.set_defaults() instead. "
