+     "This module provides an XPath engine, that can be re-used by other
+modules/classes that implement trees.
+
+In order to use the XPath engine, nodes in the user module need to mimick DOM
+nodes.  The degree of similitude between the user tree and a DOM dictates how
+much of the XPath features can be used.  A module implementing all of the DOM
+should be able to use this module very easily (you might need to add the
address@hidden method on nodes in order to get ordered result sets).")
