I install the different packages for my friend.
Log4perl is just for me. Putting it at FATAL or WARN is just a way for me to "almost turn it off".

My friend doesn't want to see a source, or have to use the command line. The best i can ask him is "put your information in the configuration file, and double click the icon to start the program."
Make him read the source code, i tried, i tried... ;o)
Maybe i'm being too kind to him :oP
But it's not too hard for me to make his life easy, so... =o)
