  * Remote ClipBoard services via PLP

+ * feature of the Psion. The Psion uses a file C:\System\Data\Clpboard.cbd
+ * for storing the content of its clipboard. This file can be accessed like
+ * any other regular file on the Psion using the @ref rfsv implementation.
+ * This class handles notification about changes of this file.
+ * There are two methods of notification implemented. Using @ref waitNotify ,
+ * a blocking method can be used and using @ref sendListen followed by
+ * @ref checkNotify , a polling approach (usable for GUI programs) can
+ * be implemented.
