+
+  \title Outliner to show use of DOM
+ 
+  This example presents a small outliner program to show the basic usage of
+  the \link xml.html#dom DOM classes \endlink. The format of the outlines
+  is the OPML format as described in http://www.opml.org/spec.
+
+  This example shows how to load a DOM tree from an XML file and how to
+  traverse it.
+ 
+  <hr>
+ 
+  Sample XML file (todos.opml):
+ 
+  \include xml/outliner/todos.opml
+ 
+  <hr>
+ 
+  Header file (outlinetree.h):
+ 
+  \include xml/outliner/outlinetree.h
+ 
+  <hr>
+ 
+  Implementation (outlinetree.cpp):

+  \include xml/outliner/outlinetree.cpp
+ 
+  <hr>
+ 
+  Main (main.cpp):
