92 * The RELAY command has a special purpose. It is always built the following way:
93 * <sender> RELAY <destination> <command>[ <list of parameters>]
94 * The <sender> is a single numeric nick of a server or user. <destination> can be:
95 * - a numeric-nick of a server (2 characters long): eg., AD
96 * - a numeric-nick of a user (5 characters long): eg., ADAAB
97 * - a numeric-nick of an unregistered user (6 characters long): eg., !ADAAB
98 * <command> is a subcommdn of RELAY.
100 * If we receive such a message, we relay the message to the server of <destination>.
101 * If we are the target, we check <command> and call the related subcommand handler.
103 * Therefore, this interface can be used to relay messages through the network without
104 * specifying new commands.
