Aha! Yes, it should do exactly that. I think I know what the problem is as
well. parse_opts detects the difference between the options and the help
text because the latter follows tab characters, and the former is before
any tab characters. The documentation is correct about this, but I wouldn't
expect you to have read all that anyway.

However, I should say that the ever wonderful Lotus *#?! Notes program here
has carefully converted my tabs to spaces and totally stuffed it up. So if
you could put 'yes' into emacs and M-x tabify with the whole thing
selected, or something else similar, it should start working properly.
Sorry about that - just more ammo for my personal vendetta against the
worst email program in the universe.

Ah, ok. I haven't used the state machine facilities yet, but I can see how
that might be handy.

Cheers,
