---------------

    Zope defines a small set of built-in variables such as 'request'
    and 'user', which are described in the chapter entitled "Advanced
    Page Templates":AdvZPT.stx. You will also learn how to define your
    own variables in that chapter.

       The example 'path expressions' we've seen so far are:

       here/title
       here/insertme
       template/title
       request/URL
       user/getUserName
       container/ObjectIDs

       Perhaps just a very small introductory discussion of these top-level paths (built in variables ?): 'here',
       'template', 'request', 'user' and 'container' might not go astray... and of course examples, examples,
       examples of how they can be used and why they are cool.
