Hi QingFeng, I think you should join the PUPS mailing list ( see
http://minnie.tuhs.org/mailman/listinfo/pups ), as the people on
the list should be able to answer your questions.

Hope this helps, and if you have other questions please e-mail them
to the PUPS mailing list, so that we can all help you out.
