Hi Chris,
Good to have you around! One unrelated question. JSR47 has a ConsoleHandler that logs
to System.err. JLog has a ConsoleHandler that logs to System.out and ErrorHandler that
logs to System.out. Do you know why Graham chose to have ConsoleHandler log only to
System.err? Your model seems to make more sense... Just curious. Ceki
