About Source tarball

[mj lane]

Hello,

 I thank you for giving me how to use a trick. I am a low-profile person in
the field of software and english. I am very interested in the construction
of creating an OS in the application of emacs. I have a question, what is
the function or purpose in GNU Guix 1.3.0 Source tarball? Source tarball
can replicate or modify the way I built the OS later? I hope team guix can
give you an answer.

thanks.
