That's what I'm trying to do.  I get my help with Pod::Usage, which
pulls the help text from the pod and then exits.  If there's a way to
prevent it from exiting, it isn't documented.

The catch, here, is that a user using --help will get the Gnome help and
not be told that the other help exists.  They'd probably figure it out
before too long, but it's not ideal.

I was aiming at getting both my help and the Gnome help for
completeness.  That said, there are screenfulls of Gnome options that
are probably never going to be used, so perhaps I'm better-off without
them.  I could just add a note to say standard Gnome options can also be
used.

Ahh.  I had forgotten all about "--".  More evidence that it's always
best to leave a job to a module when you can :-)

Thanks for the ideas.
