=head1 NAME

POE::Component::IRC::Plugin::BotTraffic - A PoCo-IRC plugin that generates
events when you send messages

=head1 SYNOPSIS

 use POE::Component::IRC::Plugin::BotTraffic;

 $irc->plugin_add( 'BotTraffic', POE::Component::IRC::Plugin::BotTraffic->new() );

 sub irc_bot_public {
     my ($kernel, $heap) = @_[KERNEL, HEAP];
     my $channel = $_[ARG0]->[0];
     my $what = $_[ARG1];

     print "I said '$what' on channel $channel\n";
     return;
 }

=head1 DESCRIPTION

POE::Component::IRC::Plugin::BotTraffic is a L<POE::Component::IRC|POE::Component::IRC>
plugin. It watches for when your bot sends privmsgs to the server. If your bot
sends a privmsg to a channel (ie. the recipient is prefixed with '#', '&', or
'+') it generates an C<irc_bot_public> event, otherwise it will generate an
C<irc_bot_msg> event.

These events are useful for logging what your bot says.

=head1 METHODS

=head2 C<new>

No arguments required. Returns a plugin object suitable for feeding to
L<POE::Component::IRC|POE::Component::IRC>'s C<plugin_add> method.

=head1 OUTPUT

These are the events generated by the plugin. Both events have C<ARG0> set
to an arrayref of recipients and C<ARG1> the text that was sent.

=head2 C<irc_bot_public>

C<ARG0> will be an arrayref of recipients. C<ARG1> will be the text sent.

=head2 C<irc_bot_msg>

C<ARG0> will be an arrayref of recipients. C<ARG1> will be the text sent.

=head2 C<irc_bot_action>

C<ARG0> will be an arrayref of recipients. C<ARG1> will be the text sent.
