I like the general direction but one thing makes me a little confused...

How does "opt" know that I am looking for the arguments to the --num command line argument and not the --file one? I guess I would expect an interface more like:

for o, value in opt: if o=='-n' or o=='--num': ncopies = optparser.needtype(value, 'integer')
