;	Change History (most recent first):
;
;		 <3>	 2/17/92	kc		Change case of SETUPNOTIFICATIONMGR, USENEWNMTASK,
;									KILLOLDNMGLOBAL GLUNMINST, and GLUNMRMV.
;		 <2>	 2/13/92	RLM		Patch roll-in
;		 <3>	 12/4/91	csd		#1016448: Added support for Scruffy. Changed the patch to
;									InitApplZone which calls FlushApplNM when Scruffy is running
;									because Scruffy’s version of InitApplZone already calls
;									FlushApplNM.
;		 <2>	 9/21/90	VL		Added patches to patch out routines in ci and portable ROMs for
;									Notification Manager.
;		 <1>	 6/26/90	DTY		First checked in.  This file was Originally
;									NotificationMgrPatchTail.  Since the Notification Manager is now
;									a linked patch, NotificationMgrPatchHead is no longer necessary.
;									This file now uses the new LinkedPatchMacros, instead of the old
;									PatchMacros.

; The Notification Manager needs to be implemented on the Plus, SE, and II ROMs.
; And it needs to be patched on IIci and Portable ROMs. The only routine that is
; currently patched is NMTask but we also have to initialize the globals (after getting
; rid of the old ones).
