[Unix] A diff, especially a diff stored under the set of version-control tools called SCCS Source Code Control System or RCS Revision Control System. See change management. 3. A small quantity, but not as small as epsilon. The jargon usage of delta and epsilon stems from the traditional use of these letters in mathematics for very small numerical quantities, particularly in "epsilon-delta" proofs in limit theory as in the differential calculus. The term delta is often used, once epsilon has been mentioned, to mean a quantity that is slightly bigger than epsilon but still very small. "The cost isnt epsilon, but its delta" means that the cost isnt totally negligible, but it is nevertheless very small. Common constructions include "within delta of ---", "within epsilon of ---": that is, "close to" and "even closer to". [Jargon File]
