The format here is a bit inconsistent. Perhaps:

  options ([+] can be repeated, [?] are flags):

I think actually sticking ^ on the option name itself is a little bizarre and
might lead to some minor confusion.

Also, we should probably figure out a way to have aliases for some of these
options so we can fully normalize the scheme. Consider:

> +   -y --noninteractive^   do not prompt, automatically pick the first choice

Having --no-noninteractive seems really sad. We could make --noninteractive
hidden and then advertise --no-interactive as the long version.

Also, I don't think --no-no-backup is a good idea. --backup should be its
negation.

Wat. That's maybe a little too generalized.
