;;; 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.

(description
"Microscheme, or @code{(ms)} for short, is a functional programming
language for the Arduino, and for Atmel 8-bit AVR microcontrollers in general.
Microscheme is a subset of Scheme, in the sense that every valid @code{(ms)}
program is also a valid Scheme program (with the exception of Arduino
hardware-specific primitives). The @code{(ms)} compiler performs function
inlining, and features an aggressive tree-shaker, eliminating unused top-level
definitions. Microscheme has a robust @dfn{Foreign Function Interface} (FFI)
meaning that C code may be invoked directly from (ms) programs.")
