	Change History (most recent first):

		<10>	  5/6/92	DCL		NIIM: Moved KeyTrans back from TextUtils to Events and added
									synonym KeyTranslate.
		 <9>	 3/26/92	JSM		Rolled this file into SuperMario project.
		 <8>	 2/27/92	DCL		Moved OSEvents into Events.p for NIIM (New Improved Inside Mac).
		 <7>	 7/30/91	JL		Updated Copyright. Restored comments.
		 <6>	 1/28/91	LN		Checked in Database Generated File from DSG. Took out an Inside
									Mac comment. Matched parameter names to .h file.
		 <5>	11/12/90	DFH		Add highLevelEventMask, remove childDiedMessage. Isolate
									obsolete equates.
		 <4>	10/19/90	gbm		Fix Dave’s mistake. Actually, his REAL mistake was checking in a
									file that he hadn’t compiled... if he had, then he would have
									noticed the missing semi-colon!
		 <3>	10/19/90	DFH		Added convertClipboardFlag.
		 <2>	10/19/90	DFH		Added resumeFlag.
