tune: vt. [from automotive or musical usage] To optimize a
program or system for a particular environment, esp. by adjusting
numerical parameters designed as hooks for tuning, e.g., by
changing `#define' lines in C. One may `tune for time' (fastest
execution), `tune for space' (least memory use), or `tune for
configuration' (most efficient use of hardware). See bum, hot
spot, hand-hacking.
