Description
rgbasm, rgblink, rgbfix, and rgbgfx all support -V/--version to print the RGBDS version. But they do not have a way to print the basic help info, besides passing unrecognized flags ("--foobar"). Many programs support -h/--help, including GNU ones, Python ones that use argparse, and Rust ones that use clap. We could augment the usage info by suggesting to read the man page (at the gbdev URL, since the user's platform may not have man).
