Thanks, but as I wrote in my first posting I am aware of sys.argv and
was hoping to _avoid_ using it because I'd then have to kind of
re-implement a lot of the stuff already there in argparse, e.g. parsing
sys.argv for short/long options, flag/parameter options etc.
I was thinking of maybe some sort of flag that argparse sets on those
optional arguments created with add_argument() that are really given on
the command line, i.e. those that it stumbles upon them during parse_args().
