/* Interface between the opcode library and its callers.

Written by Cygnus Support, 1993.

|

The opcode library (libopcodes.a) provides instruction decoders for
|
5 |
a large variety of instruction sets, callable with an identical
|
6 |
interface, for making instruction-processing programs more independent
|
7 |
of the instruction set being processed. */
