A comment to the paragraph below was recently added via http://www.zope.org/Documentation/Books/ZopeBook/current/SimpleExamples.stx#3-35
Now the method tests to see if the current object has any parents
before it display a link to the parent. *PARENTS* is a list of the
current object's parents, and *len* is a utility function which
returns the length of a list. See Appendix A for more information
on DTML utility functions. Now view the site. Notice that now
there is no parent link when you're viewing the main zoo page.

"_" is DTMLs namespace variable (where names are looked up).
Usually this is a default, hence doesnt show up.
