     /class ExampleAppEngine
     /brief Implements the playback engine and DLNA interface for the UI.
+    In general this class calls the private implementation functions for
+    a minimal implementation required to enable media rendering on a
+    DLNA rendering device.
+
+    For a real application implementing this functionality, more robust
+    error handling should be applied, this version mostly relies on the
+    function calls to return succesfully.
