How to convert netcdf to ascii

[Tennessee Leeuwenburg]

ncdump doesn't come from Grads. It comes from a suite of tools made
available by Unidata, and may have to be compiled and installed
separately. I'm not a grads expert, so maybe grads does leverage off
those tools or something, but they are certainly available independently
also.
