# Short-Description: Starts the The Multi Router Traffic Grapher

# Description: The Multi Router Traffic Grapher (MRTG) is a tool to monitor \

#              the traffic load on network-links. MRTG generates HTML pages \

#              containing GIF/PNG images which provide a live visual \

#              representation of this traffic.
