This has a pretty minimal amount of code compared to many alternatives I’ve seen. One minor nitpick; the default help output is a bit unlike most tools. For example, I’ve never seen a tool that says “OVERVIEW:”, they simply lead with a summary line; and, all-caps “USAGE:” doesn’t read as nicely to me as “Usage:” that almost any other command-line tool would print. (For some reason caps are common in man pages but not screen dumps.)
