:wizard mode: [from {rogue}] n. A special access mode of a
program or system, usually passworded, that permits some users
godlike privileges. Generally not used for operating systems
themselves (`root mode' or `wheel mode' would be used
instead). This term is often used with respect to games that have
editable state.
