List of overlays to use with the Nix Packages collection. (For

details, see the Nixpkgs documentation.) It allows you to

override packages globally. This is a function that takes as

an argument the <emphasis>original</emphasis> Nixpkgs. The

first argument should be used for finding dependencies, and
|
|
the second should be used for overriding recipes.
