/* 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.  */
