        // activity on a server and the client not receiving data even

        // CTCP PING sporadically to ensure that its connection is still
        // functioning and, if not, terminates the bot.

        // 'Ping',

        // Sometimes it's desirable to have the bot disconnect gracefully
        // when issued a command to do so via a PRIVMSG event. The Quit
