# `stack_snapshot` in the very bottom of this file. If a package or version is
# not available on Stackage, add it to the custom stack snapshot in

# `http_archive` and add it to the `vendored_packages` attribute of
# `stack_snapshot`. Executables are defined in an `http_archive` using
# `haskell_cabal_binary`.
