"""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.

Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
