+/* 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.  */
