I'm a new python user, so pardon my simple question.  I'd like to
do some simple raster math within Python.  For example, I'd like
to read in 2 Geotiffs and add one to the other -- creating a new
output Geotiff.  I've experimented with the gdal and Numpy
libraries, but I haven't made much progress on my own.  Can
somebody send me some example code?
