# This install script provides a fully automated installation of the MBP.                                               #
# It requires systemd as the running init system.                                                                       #
# It installs Java, Mosquitto, MongoDB and Tomcat8 to run the MBP.                                                      #
# Moreover it installs maven to build the necessary files.                                                              #
