	Examine the input file to see if it's a MacBinary file.  If it is

	converted, the original file is deleted and the resulting file is
	designated by 'outPGPSpec'.
	
	creator and type code pointers may be

	The output file may have a different name than the original because
	its Mac creator/type codes may be mapped into a file name extension.
