      These are the libraries that are part of the Nix project. They are used
      by the Nix CLI and other tools.

      If you need to use these libraries in your project, we recommend to use
      the `-c` C API libraries exclusively, if possible.

      We also recommend that you build the complete package to ensure that the unit tests pass.
      You could do this in CI, or by passing it in an unused environment variable. e.g in a `mkDerivation` call:

      ```nix
        buildInputs = [ nix.libs.nix-util-c nix.libs.nix-store-c ];
        # Make sure the nix libs we use are ok
        unusedInputsForTests = [ nix ];
        disallowedReferences = nix.all;
      ```
