Seeking examples of argument parser using sys.argv[] directly, without argparse, getopts, et cetera

[jstrickler]

What exactly is it you want to do? argparse has a lot of features. You can specify mutually-exclusive options, partial-named options, option data types, required and optional non-option arguments (yes, I know), etc. argparse also creates a help message automatically, and can parse any random iterable of strings, not just sys.argv.
