Doesn't need to be autogenerated, I have long used an array of text
strings as usage-help, with the first line serving as the heading as
well as the one-line description.

I like the idea of incorporating it all in a getopt()-style function.  In
such case, one needs to make it practical for the new getopt() thing to
extract the options from the description, perhaps even the validation
criteria (regexps?).
