+;;; 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.
+;;;
