<dtml-in expr="_.getitem(foldername).objectValues()"
sort="bobobase_modification_time" reverse>
 <dtml-unless name="index_hide">
   <li>
   <a href="<dtml-var absolute_url>"><dtml-var title></a><br>
   Maintained by <dtml-var maintainer missing="No maintainer">.

 </dtml-unless>
</dtml-in>

This will work assuming there is no property "index_hide" set on the
document or containing folders and there is no object in the namespace
or name in REQUEST called "index_hide". If there is, you could put
<dtml-let index_hide="0">...</dtml-let> around the whole thing.
