26 | ;;; Commentary: | |
27 | ;;; | |
28 | ;;; When loaded, this module returns a monadic procedure of at least one | |
29 | ;;; argument: the source tree to build. It returns a derivation that | |
30 | ;;; builds it. | |
31 | ;;; | |
32 | ;;; This file uses modules provided by the already-installed Guix. Those | |
33 | ;;; modules may be arbitrarily old compared to the version we want to | |
34 | ;;; build. Because of that, it must rely on the smallest set of features | |
35 | ;;; that are likely to be provided by the (guix) and (gnu) modules, and by | |
36 | ;;; Guile itself, forever and ever. | |
