+      This view demonstrated a tree structure, where there's a recursive relationship
+      between records on the same table.
+    <p>
+    <p>
+      It also demonstrates how to extend the builtin <em>list.html</em> template, and
+      pass your own parameters to the template. E.g. the parameter: <em>foo</em>, which
+      has the value <b>{{ foo }}</b>, passed in dynamically from the <em>{{ h.get_current_view().name }}</em> view.
+    </p>
