+
+    \title Qt Distribution Example
+
+    This example program modifies the hard-coded paths that are
+    compiled into the Qt library.
+
+    When distributing the Qt library, the final installation prefix is
+    very rarely the same as the prefix used when doing development.
+    You can use the code from this example to modify the following
+    hard-coded paths in Qt library:
+
+    \list
+
+    \i Prefix - Normally, all other paths are relative to the \e
+    Prefix.
+
+    \i Binaries - Location of binaries distributed with Qt (for
+    example, \e{Qt Assistant}).
+
+    \i Documentation - Location of the Qt documentation.
+
+    \i Headers - Location of the Qt headers.
+
+    \i Libraries - Location of addition libraries distributed with Qt
+    (for example, the \e qui library).
+
+    \i Plugins - Location of the Qt plugins.
+
+    \i Data - Location of applicaton specific data for all programs
+    distributed with Qt.
+
+    \endlist
+
+    <hr>
+
+    Implementation:
+
+    \include distributor/distributor.ui.h
