+<p>
+There are multiple head revisions of the branch $branch. You can access the method '$proxy_to' on 
+each of these revisions by clicking on the links provided below. If you are attempting to access 
+this method in a script, perhaps consider using this 
+#filter Filter
+$anyhead
+#filter WebSafe
+which will always go directly to one of the head revisions.
+</p>

+<ul>
+#for $head_link in $head_links

+    <li>$head_link</li>
