33 | ;;; Commentary: | |
34 | ;;; | |
35 | ;;; When loaded, this module returns a monadic procedure of at least one | |
36 | ;;; argument: the source tree to build. It returns a derivation that | |
37 | ;;; builds it. | |
38 | ;;; | |
cd295fbe LC |
39 | ;;; This file uses modules provided by the already-installed Guix. Those |
40 | ;;; modules may be arbitrarily old compared to the version we want to | |
41 | ;;; build. Because of that, it must rely on the smallest set of features | |
42 | ;;; that are likely to be provided by the (guix) and (gnu) modules, and by | |
43 | ;;; Guile itself, forever and ever. | |
