;;; Commentary:

|

;;; builds it.

|
||
;;; This file uses modules provided by the already-installed Guix. Those
|
||
;;; modules may be arbitrarily old compared to the version we want to
|
||
;;; build. Because of that, it must rely on the smallest set of features
|
||
;;; that are likely to be provided by the (guix) and (gnu) modules, and by
|

;;; Guile itself, forever and ever.
