-;;; 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.
