Crazy thought... would it make sense to have the following implicitly
use "--version" as the option flag:
parser.add_argument(action='version', version='<details>')
There are two things about the explicit '--version' that bother me:
1. It reduces the automatic provision of "standard" option spellings
2. The repetition in reading/writing 'version' 3 times is kind of annoying
(Probably a bad idea, since adding "-V" would mean having to add
"--version" as well, but figured it was worth mentioning).
Cheers,
Nick.
