I have a script to which I'd like to add a --version flag. It should print
the version number then exit, much in the same way --help prints the help

complaint about the required positional argument.
I think I could use something like nargs='*', but that would push off
detection of the presence of the positional arg to the application.
Shouldn't I be able to tell argparse I'm going to process --verbose, then
exit?
ummm, hate to say this, but have you checked the documentation? this
case is supported using an action named 'version' without doing very much.
