command options arguments <input >output
Options start with a dash, and are, y’know, optional.
An option might have its own option-argument, or it might not—it
could be -f or -o foo, depending on the command.
An argument could be pretty much anything. It might be a filename,
as in cat food, or it might be a word, like echo Hello.

Is foo an option argument, or a regular argument?
