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.
