;;; Commentary:
;;;
;;; This is the commencement, this is where things start. Before the
;;; commencement, of course, there's the 'bootstrap' module, which provides us
;;; with the initial binaries. This module uses those bootstrap binaries to
;;; actually build up the whole tool chain that make up the implicit inputs of
;;; 'gnu-build-system'.
;;;
;;; To avoid circular dependencies, this module should not be imported
;;; directly from anywhere.
;;;
;;; Code:
