   3 ///             Helper program to isolate the actual syncing into its
   4 ///             own process.  Communicates with the main barrydesktop
   5 ///             via wxWidgets IPC communication.  This belongs in its
   6 ///             own process since the sync can hang, and may need to
   7 ///             be killed from the GUI.
