      It’s “inspired” by Nix, but they’re otherwise not related in any way.

          You’re actually right that it seems to use parts of it:

          It uses low-level mechanisms from the Nix package manager, but packages are defined as native Guile modules, using extensions to the Scheme language—which makes it nicely hackable.

          As such, the packages look largely different:

          (define-public hello
            (package
             (name "hello")
             (version "2.10")
             (source (origin
                      (method url-fetch)
                      (uri (string-append "mirror://gnu/hello/hello-" version
                                          ".tar.gz"))
                      (sha256
                       (base32
                        "0ssi1wpaf7plaswqqjwigppsg5fyh99vdlb9kzl7c9lng89ndq1i"))))
             (build-system gnu-build-system)
             (synopsis "Hello, GNU world: An example GNU package")
             (description
              "GNU Hello prints the message \"Hello, world!\" and then exits.  It
           serves as an example of standard GNU coding practices.  As such, it supports
           command-line arguments, multiple languages, and so on.")
             (home-page "https://www.gnu.org/software/hello/")
             (license gpl3+)))
