=head1 NAME

Bot::IRC::Greeting - Bot::IRC greet joining users to channels

=head1 VERSION

version 1.39

=head1 SYNOPSIS

    use Bot::IRC;

    Bot::IRC->new(
        connect => { server => 'irc.perl.org' },
        plugins => ['Greeting'],
        vars    => {
            greeting => {
                greeting => 'morning',
                channels => [ '#perl', '#perl-help' ],
            },
        },
    )->run;

=head1 DESCRIPTION

This L<Bot::IRC> plugin causes the bot to greet joining users to channels.
By default, it will say something like "greetings" to whomever joins. The bot
will change the style of "greetings" to somewhat match the user's nick style.
For example, if "John" joins, the bot will say "Greetings" to him. If
"joan_" joins, the bot will say "greetings_" to her.

You can specify the greeting word and channel list with C<vars>.

    greeting => 'morning',
    channels => [ '#perl', '#perl-help' ],

If greeting isn't specified, the bot will use "greetings" as the greeting. If
a channel list isn't supplied, the bot will greet on all channels it's on. If
you specify a greeting of empty string or some other false value, the greeting
will get skipped.
