[Zope] uses for lines, token properties?

Tokens are just a list of words, lines are a list of lines. In each case
you can scan through them. If you need spaces use lines.

I think Ztables does tuples but I haven't had time to look at it yet.

Here is some code that I originally stole from zope.org. Don't tell! :)

<!--#if menu_contents-->
  <H4><!--#var title_or_id--></h4>
  <p>
  <!--#in menu_contents-->
    <!--#if sequence-item-->
    <!--#var expr="REQUEST.set('sc',
_.string.split(_vars['sequence-item'],'|'))" fmt=""-->
      <!--#if expr="PATH_INFO == sc[1]"-->
        <IMG WIDTH="8" HEIGHT="12" ALIGN="top" SRC="<!--#var
BASE1-->/images/arrow" BORDER="0" VALIGN="center">
        <STRONG> <!--#var expr="sc[0]"--><BR></STRONG>
      <!--#else-->
        <IMG WIDTH="8" HEIGHT="12" ALIGN="top" SRC="<!--#var
BASE1-->/images/blank" BORDER="0" VALIGN="center">
        <A HREF="<!--#var BASE1--><!--#var expr="sc[1]"-->">
        <!--#var expr="sc[0]"--></A><BR>
      <!--#/if-->
    <!--#/if-->
  <!--#/in-->
  </P>
<!--#/if menu_contents-->

menu_contents is a lines property of the folder. If it doesn't exist is
is inherited. So you only need to declare it when you want the menu to
change. Each line is a menu item and a URL seperated by a '|'. The code
splits it. It even checks if a URL is the current URL and puts in a
pointer and the menu item in bold.

(Full credit to zope.org, It would have taken me forever to come up with
this!)

This code should help with this, too!
