## To run the reconstruction, we need the following global variables:
## - JUGGLER_INSTALL_PREFIX: Install prefix for Juggler (simu/recon)
## - JUGGLER_DETECTOR:       the detector package we want to use for this benchmark
## - DETECTOR_PATH:          full path to the detector definitions
##
## You can ready config/env.sh for more in-depth explanations of the variables
## and how they can be controlled.
