# This is a simple simulation example showing the following things
#
# a) how to run a simple background event simulation with some parameter customization
# b) how to run a simulation producing signal events based on a custom external generator
# that can adapt its behaviour depending on the characteristics of the background event.
set -x
# PART a)

# PART b)
# produce pythia8 events generated according to the configuration given in a file 'adaptive_pythia8.macro'.
# the settings as such that pythia8 is initialised using the 'pythia8_inel.cfg' configuration file.
# the customisation allows the user to generator to receive and react to a notification that signals
# the embedding status of the simulation, giving the header of the background event for determination
# of subsequent actions. In this case, the number of pythia8 events to be embedded is calculated according
# to a formula that uses the number of primary particles of the background events
