+ *  ======== dbgce.c ========
+ *  Purpose:
+ *      Provide debugging services for DSP/BIOS Bridge Mini Drivers.
+ *
+ *  Public Functions:
+ *      DBG_Exit
+ *      DBG_Init
+ *      DBG_Trace
+ *
+ *  Notes:
+ *      Requires gt.h.
+ *
+ *      This implementation does not create GT masks on a per WMD basis.
+ *      There is currently no facility for a WMD to alter the GT mask.
+ *
+ *! Revision History:
+ *! ================
+ *! 15-Feb-2000 rr: DBG_Trace prints based on the DebugZones.
+ *! 03-Feb-2000 rr: Module init/exit is handled by SERVICES Init/Exit.
+ *!             GT Changes.
+ *! 29-Oct-1999 kc: Cleaned up for code review.
+ *! 10-Oct-1997 cr: Added DBG_Printf service.
+ *! 28-May-1997 cr: Added reference counting.
+ *! 23-May-1997 cr: Updated DBG_Trace to new gt interface.
+ *! 29-May-1996 gp: Removed WCD_ prefix.
+ *! 20-May-1996 gp: Remove DEBUG conditional compilation.
+ *! 15-May-1996 gp: Created.
