# by geant4/examples main programs, the C-pre-processor variables
# corresponding to the original environment variables are set, but
# there is no dependency in the Geant4 kernel; a user may instantiate
# a session from this list without setting any environment variables.
# However, if he/she sets no environment variables, then the
# C-pre-processor variable G4UI_USE_TERMINAL is set by default, although
# there is no need to use it.
