+	  <CS11>	11/16/97	djb		Change Unicode.h to UnicodeConverter.h.
+	  <CS10>	 11/7/97	msd		Remove prototype for CompareUnicodeNames(). Add prototype for
+									FastUnicodeCompare().
+	   <CS9>	10/13/97	djb		Add encoding/index macros and add prototypes for new Get/Set
+									encodding routines.
+	   <CS8>	 9/15/97	djb		InitUnicodeConverter now takes a boolean.
+	   <CS7>	 9/10/97	msd		Add prototype for InitializeEncodingContext.
+	   <CS6>	 6/26/97	DSH		Include  "MockConverter" prototype for DFA usage.
+	   <CS5>	 6/25/97	DSH		Removed Prototype definitions, and checked in Unicode.h and
+									TextCommon.h from Julio Gonzales into InternalInterfaces.
+	   <CS4>	 6/25/97	msd		Add prototypes for some new Unicode routines that haven't
+									appeared in MasterInterfaces yet.
+	   <CS3>	 6/18/97	djb		Add more ConversionContexts routines.
+	   <CS2>	 6/13/97	djb		Switched to ConvertUnicodeToHFSName, ConvertHFSNameToUnicode, &
+									CompareUnicodeNames.
