      # NOTE: --no-check option added to skip check on whether PLT file needs to
      # be updated. The version in the cached _build file will be used, hence
      # not slowing down the build while the PLT file gets rebuilt.
      # The --no-check option will have to be removed on a single build if
      # Elixir or Erlang versions update, but can then be re-instated.
