Doug, thank you for the reply.

I did checked out the usage.html there, it is offering no help other
than confusion. If you do register_options(), you will definitely fail.
It will throw me back to the initial question about passing what kind of
a conf to setup() or register_options().

What I can do now is be patient and wait for a stable API/release. :)
