As Joseph Method already mentioned, you are probably confusing the
existance of a Python package ('worldcookery') in lib/python with
publishable objects. A Python package like lib/python/worldcookery is
just a piece of software. Somethign that is accessible via URL
("publishable") is an *object* that usually lives in the ZODB (see
chapter 6 of my book) and is presented through views (chapter 7).
Remember, Zope is called the Z Object Publishing Environment...

In other words, Zope 3 development does NOT work like PHP or ASP
development where something on the filesystem immediately represents
something that is accessible via a URL.

My advice for you is to go to Chapter 7 and follow the instructions on
how to create and add recipes (through the add forms, accessible from
the Add menu). I'm sure it'll all be clearer after that.
