GMCP for Developers

GMCP Specification
MoralDecay pushes structured out-of-band data over GMCP — vitals, room info, combat targets, chat, and Mudlet GUI/map auto-configuration. If you're building or scripting a client, this spec documents every package, field, and quirk, including Char.Vitals, Room.Info, Target.Info, and more.
