      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.
