;;; 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.
