"""A simple example bot.
This is an example bot that uses the SingleServerIRCBot class from
irc.bot.  The bot enters a channel and listens for commands in
private messages and channel traffic.  Commands in channel messages
are given by prefixing the text by the bot name followed by a colon.
It also responds to DCC CHAT invitations and echos data sent in such
sessions.
The known commands are:
    stats -- Prints some channel information.
    disconnect -- Disconnect the bot.  The bot will try to reconnect
                  after 60 seconds.
    die -- Let the bot cease to exist.
    dcc -- Let the bot invite you to a DCC CHAT connection.
