# USAGE
#
# If you need to use different versions for tools like CBMC, modify this file:
# .github/workflows/proof_ci_resources/config.yaml
#
# If you want the CI to use a different GitHub-hosted runner (which must still
# be running Ubuntu 20.04), modify the value of this key:
# jobs.run_cbmc_proofs.runs-on
