 * Description: platform independant top-level API for
 *              remote control of graphPackage-applications
 * Exported functions:
 *              graphRemoteRegister - called by applications during
 *			initialisation phase to register the application
 *			specific function that handles textual commands 
 *			and performs the appropriate actions.
 *              graphRemoteCommand - called by the remote-control client
 *			to place a command. The returned status gives an
 *			indication whether the command was received by 
 *			a graph-application and whether it could be
 *			correctly parsed and executed.
 * HISTORY:
 * Last edited: Nov 10 15:07 1999 (fw)
 * * Apr 29 16:05 1999 (edgrif): Changed call to xt level remote command
 *              to be graphdev call.
