And /please/ have long-option alternatives for each of the short
opts. E.g. --dry-run. It is okay for there to only be a long-opt
version of a switch. Also, always have -h/--help and (probably)
-V/--version. Try to find a similar existing too and match its
options where appropriate (e.g. patch(1) has the essential --dry-run
and -b/--backup). I don't know if there are standards for this kind
of thing, so make consistency a goal, but don't freak out if it's an
impossible goal to meet <wink>

Please, no tilde files. AFAIK, that's an Emacs-ism that some other
editors have adopted, but few command line oriented programs have.
One of the beautiful things about using vc-mode or cvs-mode under
(X)Emacs is the total lack of dumb ~ files that need cleaning up
('cause they're all backed up under RCS or CVS anyway, so why make ~
backups?).

Oh jeez, acronym explosion time. Some How, I Think Not Obvious.
