/* Interface between the opcode library and its callers.
   Written by Cygnus Support, 1993.

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