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.
