I'd like to give you an improved ESRI file, Frank which *only* includes 
codes used by ESRI. Note that ESRI included most (but not all) of the 
EPSG codes in their coding scheme. They also seem to have tried to avoid 
collisions. There were somem problems in the last file I gave you with 
Stateplane projections in feet.
