+Avoid showing title of toplevel index page
+------------------------------------------
+
+If you don't like having "index" appear on the top page of the wiki,
+but you do want to see the name of the page otherwise, you can use a
+special `HAS_PARENTLINKS` template variable that the plugin provides.
+It is true for every page *except* the toplevel index.
+
+Here is an example of using it to hide the title of the toplevel index
+page:
+
+       <TMPL_LOOP NAME="PARENTLINKS">
+       <a href="<TMPL_VAR NAME=URL>"><TMPL_VAR NAME=PAGE></a>/ 
+       </TMPL_LOOP>
+       <TMPL_IF HAS_PARENTLINKS>
+       <TMPL_VAR TITLE>
+       </TMPL_IF>
