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