	Change History (most recent first):

            2.0			08/13/2008			Add Leopard user client API for supporting 64-bit user processes.
											Now requires Xcode 3.0 or later to build.
			
            1.1			05/22/2007			Perform endian swapping when called from a user process running
											under Rosetta. Updated to produce a universal binary. Now requires
											Xcode 2.2.1 or later to build.
			
			1.0d3	 	01/14/2003			New sample.
