# In particular, Geant4Py must be matched exactly to a given Geant4 release

# Require Python 3 or newer, calling Interp before Libs to help find a consistent set
# Boost python requirement is reliant on correct user config (not yet known how to check
# which Python an install of Boost Python uses)...
