# - 2025, Feb -- Riccardo Maria BIANCHI <riccardo.maria.bianchi@cern.ch>
#                Added dedicated DumpGeo flags as GeoModel.DumpGeo; 
#                also,  support the use of DumpGeo transforms and other
#                Athena jobs -- that is, not standalone. This is useful 
#                when we want to dump the geometry that comes out as the 
#                output of an Athena job.
