Change all license headers, except guix/build/* and ld-wrapper.scm, with
this code:
(use-modules (guix build utils)
(srfi srfi-1))
(fluid-set! %default-port-encoding "UTF-8")
(substitute* (remove (lambda (f)
(or (string-contains f ".tar.")

(string-contains f ".so")
(string-suffix? ".o" f)
(string-suffix? ".a" f)
(string-suffix? ".go" f)
(string-suffix? ".pdf" f)
(string-suffix? ".png" f)
(string-suffix? ".info" f)
(equal? (basename f) "guix-daemon")
(equal? (basename f) "nix-setuid-helper")
(string-contains f "nix-upstream/")
(string-contains f "distro/packages/bootstrap/")))
(find-files "." "\\.[a-z]+$"))
(("^([[:graph:]]+) This file is part of Guix." _ comment-start)
(string-append comment-start " This file is part of GNU Guix."))
(("^([[:graph:]]+) Guix --- Nix package management.*" _ comment-start)
(string-append comment-start
" GNU Guix --- Functional package management for GNU\n"))
(("^([[:graph:]]+) Guix is " _ comment-start)
(string-append comment-start " GNU Guix is "))

(string-append comment-start " along with GNU Guix."))
(("^([[:graph:]]+) Copyright \\(C\\)" _ comment-start)
(string-append comment-start " Copyright ©")))
Change headers using C-style comments manually.
