   2  * Ingest NEXRAD (wsr88d) data and output 3 gif images representing
   3  * Reflectivity, Velocity and Spectrum width.

   5  * This example is the most minimum of coding that you need to do
   6  * to achieve good results from using the RSL code.
   7  *
   8  * This is short and sweet to demonstrate the simplicity of use for
   9  * the RSL.
