If the user gives the /bar argument, the program should save the
downloaded files to /bar. But I'm assuming that the user could be dumb or
too lazy, in which case --fetch-udpate should use the parser.set_defaults
value i.e. /foo

Hi,
I'm using optparse module to parse all options and arguments.
My program uses mostly option arguments hence my len(args) value is always
zero. I need to check if the user has passed the correct number of option
arguments. Something like:

I don't think that's actually what you want to do. Yes arguments are
not to be used directly as option arguments (otherwise why have option
arguments anyways ;-) but each option argument is usually evaluated
under the evaluation of the actual option and optparse will error on
invalid use of the
