[Zope] Zope 2.7 and zhttp_handler

I'm starting to play with Zope 2.7 and I can't figure out how to publish my scripts as described in "How To Publish Your Own Python Modules" (http://www.zope.org/Members/Amos/ZPublisher) by Amos. I used this technique for older versions of Zope. Is there a 'how to' for Zope 2.7 that covers publishing your own modules? Ray
