#!nix-shell -p nix -i "nix-env -qaP --no-name --out-path --arg checkMeta true --argstr path $PWD -f"

  hydraJobs = import (path + "/pkgs/top-level/release.nix")
    # Compromise: accuracy vs. resources needed for evaluation.
    {
      supportedSystems = [
        "aarch64-linux"
        "aarch64-darwin"
        #"i686-linux"  # !!!

        "x86_64-darwin"
      ];

      nixpkgsArgs = {
