How to compile nixpkgs.emacsPackages against this flake

[lafrenierejm]

As a Nix newb, it's unclear to me how I would go about compiling Emacs package recipes from nixpkgs against an Emacs built via this flake. Would it be feasible to add instructions to the readme for doing so?

@lafrenierejm I'm newb too, but I think you could specify different name for this package (such as emacs-nightly) as following

{ inputs =
  { emacs.url = "github:cmacrae/emacs"; };
  outputs =
  { overlays = { emacs-nightly = inputs.emacs.overlay; }; };
}

Please correct me if I'm wrong.
