+# this is a very rustic script for generating png maps from a model
+# the model is expected in /var/www/html/sites/map.png
+# and the output is located in the same dir as livemap.png
+#
+# this has many drawbacks, as it needs a cylindric projection map
+# (there's almost no such map out there) and manual calibration
+# you want to use the kml-based googlemap applet instead
