Modernize command-line options #2

Closed rrthomas closed 3 years ago

rrthomas commented 3 years ago

Add long options, use getopt_long (use gengetopt?), and as a result use help2man to generate the options documentation for the man page.

Gengetopt-based overhaul done; it remains to use help2man.
