[Zope] Newbie:Navigational bar

[Alexander Staubo]

Yep. Once upon a time I wrote this. It might not be the best or most
efficient way to do it, but darn, it works (it would have been the best
way if #in supported reverse iteration, because then we could skip the
temporary "dirs" variable).

The use of absolute_url() might not be to your taste -- if you use
recursive acquisition, the navigation bar will link to the true location
of the object, not to the acquired path. You can fix this by maintaining
a temporarily variable for the URL.

<!--#call "REQUEST.set('dirs', [])"-->
<!--#in PARENTS skip_unauthorized-->
  <!--#call "dirs.insert(0, _['sequence-item'])"-->
<!--#/in-->
<!--#in dirs skip_unauthorized-->
  <!--#if "not _['sequence-start']"--> : <!--#/if-->
  <a href="<!--#var "_['sequence-item'].absolute_url()"-->"><!--#var
"_['sequence-item'].title_or_id()"--></a>
<!--#/in-->

Now I'll let the more experienced Zopistas tear this code to pieces and
tell you the Right Way. :-)
