If \f(CW\*(C`stderr\*(C'\fR is set to a false value, it will log to \s-1STDOUT\s0. The default setting for \f(CW\*(C`stderr\*(C'\fR is 1, so messages will be logged to \s-1STDERR\s0 by default. The constructor can also take an optional parameter \f(CW\*(C`color\*(C'\fR, whose value is a hashref of color configuration options, any levels that are not included in the hashref will be set to their default values. .SH "COPYRIGHT AND LICENSE" .IX Header "COPYRIGHT AND LICENSE" Copyright 2002\-2009 by Mike Schilli and Kevin Goess . .PP This library is free software; you can redistribute it and/or modify it under the same terms as Perl itself.
