;;; Commentary:
;;;
;;; This module defines a procedure that can be used to create a complete
;;; avr-toolchain package.  The procedure must not be used at the top level,
;;; to avoid cyclic module dependencies caused by the (gnu packages
;;; cross-base) module referring to top level bindings from (gnu packages
;;; gcc).
;;;
;;; It also contains packages for working with or targeting the AVR system.
