I wanted to have a look into this but currently my computer is
downloading (and then compiling) the 2Gig tetex-live... I will
investigate it tomorrow.

Hint: The manual and guix-cookbook sources are in the main Guix git
repository under the "doc/" directory.

The website is in the maintenance.git repository under "hydra/". In
hydra/berlin.scm, you will find reference on how the Cookbook is built:

GUIX_MANUAL=guix-cookbook guix build -f doc/build.scm

I think a partial answer to the problem is that the Cookbook's texi
source is only available in English and German language: There is no
es/fr/ru/ch translation in the Guix source repository.

I think the 

(define %languages

should either be controlled by environment variables like with the
GUIX_MANUAL or should be dependent on the value of %manual.

BTW, the link to the translation project 404s too:

https://translationproject.org/domain/guix-cookbook.html

Yes, I stumbled upon this comment in doc/build.scm :-):

;; alphabets doesn't work:

Thanks for your report,
