#  Arguments: 
#    1 - relative path regression test file staging location 
#    2 - absolute path to location of software under test
#    3 - build identifier for software under test
#  
#  Note: 
#    Tests and benchmark files are stored in the epanet-example-networks repo.
#    This script retreives them using a stable URL associated with a release on 
#    GitHub and stages the files for nrtest to run. The script assumes that 
#    before-test.sh and gen-config.sh are located together in the same folder.
