# This script uses the data pulled with
# maintainers/scripts/haskell/hydra-report.hs get-report to produce a list of
# failing builds that get written to the hackage2nix config. Then
# hackage-packages.nix gets regenerated and transitive-broken packages get
# marked as dont-distribute in the config as well.
# This should disable builds for most failing jobs in the haskell-updates jobset.
