How to package a command-line tool in Nix?

Suppose you have a simple collection of bash scripts making up a command line tool, with a primary script in bin/ and some library scripts in lib/, all to be packaged with Nix using tool.nix with a default.nix for convenience:

scriptdir
 └─ bin/
     └─ tool
 └─ lib/
 └─ default.nix
 └─ tool.nix

What should tool.nix look like in order to correctly package this tool, allowing to execute tool in the shell with tool <args>?

After some help from IRC, the following tool.nix works:

{ stdenv }:

let

    version = "0.0.1";

in stdenv.mkDerivation 
rec 
{

    name = "tool-${version}";

    src = ./.;

    installPhase =
        ''
            mkdir -p $out
            cp -R ./bin $out/bin
            cp -R ./lib $out/lib
        '';

}

For completeness, default.nix would look like

{ pkgs ? import <nixpkgs> {} }:

pkgs.callPackage ./tool.nix {}

and can be installed by calling nix-env -f ./default.nix -i from scriptdir.
