+# This script polls gnunet-stats repeatedly to create statistics plots. 
+# Use 'collect' to collect statistics and 'plot' to plot whats been
+# collected. All plots will be written to $STATDIR as separate .png files.
+#
+# WARNING: calling 'collect' will delete all files in $STATDIR.
+#
+# Requires: gnuplot
+#
+# Note: gnuplot syntax has changed across versions. This
+# script perhaps will not produce color images with older gnuplots.
+# The script should work atleast with gnuplot 3.8k patchlevel 1.
