On *nix, there's a very nice utility that lets you parse command-line flags and arguments in a very straightforward way. There's a nice example of its use on the same page.

You would then run your program and pass arguments to it in a very standardised way:

$ ./my_app -a -b -c argument1 argument2

You can do without it and just parse them on your own but if you're aiming to make your app useful to other people it's definitely worth the effort of making it conforming.
