=head1 NAME
Log::Log4perl::Layout::PatternLayout::Multiline
=head1 SYNOPSIS
    use Log::Log4perl::Layout::PatternLayout::Multiline;
    my $layout = Log::Log4perl::Layout::PatternLayout::Multiline->new(
        "%d (%F:%L)> %m");
=head1 DESCRIPTION
C<Log::Log4perl::Layout::PatternLayout::Multiline> is a subclass
of Log4perl's PatternLayout and is helpful if you send multiline
messages to your appenders which appear as
    2007/04/04 23:59:01 This is
    a message with
    multiple lines
and you want them to appear as 
    2007/04/04 23:59:01 This is
    2007/04/04 23:59:01 a message with
    2007/04/04 23:59:01 multiple lines
instead. This layout class simply splits up the incoming message into
several chunks split by line breaks and renders them with PatternLayout
just as if it had arrived in separate chunks in the first place.
