	Change History (most recent first):

		<14>	 7/30/91	JL		Updated Copyright.
		<13>	  2/4/91	JL		change parameter names from pPSN to PSN.  Deleted
									registerOnNetwork.
		<12>	 1/28/91	LN		Checked in Database Generated File from DSG. RegisterOnNetwork
									came back because their was no note on its removal.
		<11>	 1/25/91	stb		JDR: change systemOptionMask to systemOptionsMask
		<10>	12/14/90	JWM		do some beautification of the header file
		 <9>	12/13/90	JWM		New error code, noUserInteractionAllowed (-610) for
									PostHighLevelEvent which is returned if we are establishing a
									remote connection and the application is not frontmost or is
									being coerced.
		 <8>	 9/27/90	ngk		Define GetSpecificFilterProcPtr type.
		 <7>	 9/27/90	ngk		Changed "VAR params: LONGINT" to "yourDataPtr: UNIV Ptr" in
									GetSpecificHighLevelEvent
		 <6>	 9/15/90	ngk		update to new ppctoolbox namesPortName -> PPCPortRec,
									LocationName -> LocationNameRec
		 <5>	 4/10/90	JWM		add GetPortNameFromProcessSerialNumber interface and remove two
									postingOptions that will not be implemented.
		 <4>	 3/20/90	JM		changing API for (hopefully) the last time before beta. See
									comments in the file.

		** 3.0  jwm 03/20/1990 updated for 7.0a8 changes to the API.	
		** 1.2	ngk 11/07/1989  Added registerOnNetwork and authenticateNetRequest
		** 1.1	ngk 11/04/1989 fixed GetPSNfromPort
		** 1.0	ngk 11/02/1989 initial EASE submission


	To Do:
