This processing step requires that you have both an 
'epsg' database and the database that is specified in ../settings.py.

GDAL requires data in the 'epsg' database to process for its csv files.  We 
additionally refresh the epsg_ data in the settings.DATABASE_NAME as well.

The server's GDAL_DATA must point at the the gdal directory below this one to
ensure the freshest conversion data.  This directory is an svn:external to GDAL's 
trunk data directory.


To load, run:

./process_epsg.sh 

from a bash prompt.
