;;; Commentary:
;;;
;;; When loaded, this module returns a monadic procedure of at least one
;;; argument: the source tree to build. It returns a derivation that
;;; 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.
;;;
;;; Code:
;; The dependencies. Don't refer explicitly to the variables because they
;; could be renamed or shuffled around in modules over time. Conversely,
;; 'find-best-packages-by-name' is expected to always have the same semantics.
