There's dozens of logging modules on CPAN. When it comes to logging, people typically think: "Aha. Writing out debug and error messages. Debug is lower than error. Easy. I'm gonna write my own." Writing a logging module is like a rite of passage for every Perl programmer, just like writing your own templating system.Of course, after getting the basics right, features need to be added. You'd like to write a timestamp with every message. Then timestamps with microseconds. Then messages need to be written to both the screen and a log file.And, as your application grows in size you might wonder: Why doesn't my logging system scale along with it?
