32  * Disassembler Implementation
33  *
34  * Each disassembler provides a string name (for selection with $V or -V),
35  * a brief description, and the set of operations defined in mdb_dis_ops_t.
36  * Currently the interface defined here is very primitive, but we hope to
37  * greatly enhance it in the future if we have a two-pass disassembler.
