"""
 Worldwind Java SDK example using Jython.
 Based on the AWT1Up.java demo included with WWJ (by Tom Gaskins).
 
 You must have wwj and jython installed to run this.
   jython wwj_demo.py

 You'll probably have to set two environment vars to get this working:
   export CLASSPATH=/opt/wwj/worldwind.jar
   export LD_LIBRARY_PATH=/opt/wwj:$LD_LIBRARY_PATH

 TO DO:
   - Add event listeners
   - work up support for other formats (via geotools)
