1. [techspeak] A quantitative change, especially a

small or incremental one (this use is general in physics and

engineering). "I just doubled the speed of my program!" "What

was the delta on program size?" "About 30 percent." (He

doubled the speed of his program, but increased its size by only 30

percent.) 2. [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). 3. n. 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

isn't epsilon, but it's delta" means that the cost isn't 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'.
