You can select what you want. I would do it like this.
my $log_conf = qq(
log4perl.rootLogger = DEBUG, LOG
log4perl.appender.LOG = Log::Log4perl::Appender:
+:File
log4perl.appender.LOG.filename = $ref->{config}->{Log}
log4perl.appender.LOG.mode = append
log4perl.appender.LOG.layout = Log::Log4perl::Layout::P
+atternLayout
log4perl.appender.LOG.layout.ConversionPattern = %d %p %m %n
);
"We can't all be happy, we can't all be rich, we can't all be lucky – and it would be so much less fun if we were. There must be the dark background to show up the bright colours."
Jean Rhys (1890-1979)
