However, this is normally not a lot of use, unless you turn on additional debugging output when you run MediaTomb -by adding the -D option on the command line as follows:
sudo mediatomb -D -u <User that MediaTomb runs Under> -c <MediaTomb Config File Location>
$ sudo mediatomb -D -u mediatomb -c /etc/mediatomb/config.xml
