+;;; Commentary:
+;;;
+;;; This module provides packages for cross compilation toolchains.  These
+;;; packages must not be used at the top level to avoid cyclic module
+;;; dependencies caused by the (gnu packages cross-base) module referring to
+;;; to top level bindings from (gnu packages gcc).
+;;;
+;;; The real purpose of these packages is for installation on profiles by users
+;;; and other packages should make use of the toolchain through the usual cross
+;;; compilation methods. For example, by using the `#:target' argument on
+;;; packages or `--target' on the command line.
