# This is a wrapper script that sets EPN-related env variables needed for the PDP DPL Topology generation.
# Author: David Rohr

# A reference version of this script is contained in the O2DPG repository: https://github.com/AliceO2Group/O2DPG/blob/master/DATA/tools/epn/gen_topo.sh

# The purpose of this script is to separate the topology generation (which is in O2DPG) from the setting of the EPN-related settings

# Settings for some EPN paths / names / etc.
