> Currently there are a lot of {{System.out.println()}} calls in the code, mostly in the {{sharelib}}.
> This solution is inferior to using a logger library, where we can fine-tune a lot of different things. It's desirable that we migrate these calls to Log4j.
> The preferred solution would be to use {{log4j}} {{Logger}} in our code, redirected per default to the console using {{ConsoleAppender}}. That way we wouldn't be breaking compatibility, but some of the users could redirect to another {{Appender}} s.
