# verify_artifact.sh is the top-level script that implements the logic to decide
# which individual verification script to invoke. It decides which verification
# script to use based on artifact name it is given. By putting the logic in here,
# it keeps the workflow file simpler and easier to manage. It also doubles as a means
# to run verifications locally when necessary.

# set this so we can locate and execute the individual verification scripts.
