All that is obvious.  What isn't clear from the man page is where they are
allowed, as they should be documented at the top level of things if they
are allowed everywhere, instead of being mentioned in a couple of the
commands that con use them.

Rusty's iptables HOWTO is better, and I think I'm starting to make a good
mental model.
