Codebases

Servers grouped by the codebase reported via MSSP. The CODEBASE field is used when available, falling back to FAMILY. Version numbers are stripped and known aliases are normalized (e.g. FluffOS and LDMud become LPMud, PennMUSH and ProtoMUCK become TinyMUD). Servers that do not report either field are listed under Unknown.
