      # applications its closure names, and this line is what keeps `:xmerl`
      # in it if that closure ever stops needing it. `:eex` is named for the

      # `EEx.eval_string/3` while its own application names no `:eex`, which
      # reaches the release today only through other dependencies' closures,
      # plug's and ecto's among them — so this line is what keeps every render
      # working if those ever stop needing it.
