+<H3>Creating Widget hierarchies</H3>
+
+<P>Widgets are commonly ordered into functional groups, which 
+in turn may be grouped again, creating a hierarchy of widgets. 
+FLTK makes it easy to fill groups by automatically adding all widgets 
+that are created between a <tt>myGroup-&gt;begin()</tt> and 
+<tt>myGroup-&gt;end()</tt>. In this example, <tt>myGroup</tt>  
+would be the <i>current</i> group.</P>
+
+<P>Newly created groups and their derived widgets implicitly call
+<tt>begin()</tt> in the constructor, effectively adding all 
+subsequently created widgets to itself until <tt>end()</tt> 
+is called.</P>
+
+<P>Setting the current group to <tt>NULL</tt> will stop automatic
+hierarchies. New widgets can now be added manually using 
+<tt>Fl_Group::add(...)</tt> and <tt>Fl_Group::insert(...)</tt>.</P>
