		| Abstract: | 
		Each Keck instrument presents a consistent software view to the applications programmer. A set of ``plug compatible'' applications has been developed that can be used with any instrument. Because image capture software uses the same keyword library to collect data for the image header, a given observation can be ``replayed'' by extracting keyword-value pairs from the image header and passing them back to the control system. |
