Sometimes Marmotta just works,
sometimes another instance Tomcat starts on its own and needs to be shut
down first "sudo service tomcat7 stop",
sometimes the installation wizard looks weird at the last screen after
confirming the installation path,..and Marmotta does not start on its own
at the default localhost:8080 like it should (if I recall correctly)
