$usage = "Usage: netmond2tput.pl <elab-file> <planet-file> <planet-logfile>

Takes two files in the format generated by netmond, and an magent log
file and creates an xplot throughput graph with both of them
comparable. The vertical green bars are the throughput numbers
generated by the magent. The elab-file is red. The planet-file is
blue. Limitation: This only gives the *aggregate* throughput for the
nodes involved. The aggregate of all streams. This is because there is
no way to correlate individual streams on one elab with those on
PlanetLab with streams of the other without more information.";
