[cups.general] Minimum EPSGS file requirement for CUPS

[John Frankish]

In order to minimise the footprint of cups-1.3.5 on my system, I'd 
like to use only the files from epsgs-8.15.4 that are absolutely 
required for cups to function properly. If I understand correctly, 
this is the ps to raster driver for cups and associated files.

Is there a list of cups required files from epsgs somewhere?

Thanks
John
