This part should go under the “---” line, otherwise they will be part of

I am not a laywer, but is “Guix Together” a legal entity?  It’s probably
better to put the authors’ names here instead.

Nitpick: The new Gexp style could be used instead.

The ‘parallel-build?’ flag should also be respected.

This sounds like an advert; I suggest

  “Programming language that aims for control and simplicity”

Again, “fun” is probably not the best word.  “high quality” is
subjective and as a user, it doesn’t really tell me anything.

Capitalize “Rust” and “OCaml”.

Package builds fine!
