+= Access a top level package from the Nixpkgs/NixOS repo
+
+In <<_introducing_a_dependency>>, we wrote a shell script that needed
+access to the Linux `cowsay` command.
+To accomplish this, we added a step to the `installPhase` that
+modified that script by including the full path to `cowsay`.
+
+Let's see a different approach.
+This time we won't start with an existing script;
+we'll create it during installation.
