If you don't use Emacs, please run ./etc/indent-code.el before
submitting packages.  :-)

I used (string-append "CC=" ,(cc-for-target)) here to aid
cross-compilation.

And added #:tests? #f instead of deleting the phase.

I removed the last sentence, because that URL just redirects to the home
page and did not actually contain a detailed format description.  Also,
it was missing punctuation, and lacked two spaces after the previous
punctuation (did you forget to use 'guix lint'?).

This is GPL2+, as explicitly stated in the README.

Applied with those changes, thanks!
