This document lists the different user modes, channel modes, and channel
user modes that ngIRCd supports.

Channel modes are attributes of specific channels which are valid for all

users to lists (e.g. "invite list", "ban list"), others have parameters
(like "channel key"), most are simple flags (like "moderated").

(1) This mode is not set by ngIRCd itself but by services. ngIRCd handles
    the mode transparently and possibly adjusts its behaviour.
