## Global configuration variables for the benchmark scripts
## The script defines the following environment variables that are meant to
## be overriden by the Gitlab continuous integration (CI)
##
## - JUGGLER_DETECTOR: detector package to be used for the benchmark
## - JUGGLER_N_EVENTS: #events processed by simulation/reconstruction
## - JUGGLER_INSTALL_PREFIX: location where Juggler (digi/recon) is installed
## - JUGGLER_N_THREADS: Number of threads/processes to spawn in parallel
## - JUGGLER_RNG_SEED: Random seed for the RNG
##
## It also defines the following additional variables for internal usage
## - LOCAL_PREFIX: prefix for packages installed during the benchmark
## - DETECTOR_PREFIX: prefix for the detector definitions
## - DETECTOR_PATH: actual path with the detector definitions
##
## Finally, it makes sure LOCAL_PREFIX and JUGGLER_PREFIX are added to PATH
## and LD_LIBRARY_PATH
