Yes just thought I'd mention/remind that the EPSG file isn't used for 
anything at all except displaying it to the user in the Tcl/Tk GUI 
startup. All the data used in the GPJ_ GRASS functions comes from data 
files contained within the GRASS source code. This is really a whole lot 
of fuss over something that isn't very important! Perhaps a copy of the 
file could just be kept in the GRASS source code? It needs a python script 
to generate it from the .csv files in lib/proj --it is one of the scripts 
in the pymod directory in the GDAL source treem, not sure which one.
