-# LUFA GCC Compiler Buildsystem Makefile Module.
-# -----------------------------------------------------------------------------
-# DESCRIPTION:
-# Provides a set of targets to build a C, C++ and/or Assembly application
-# via the AVR-GCC compiler.
-# -----------------------------------------------------------------------------
-# TARGETS:
-#
-# size - List built application size
-# symbol-sizes - Print application symbols from the binary ELF
-# file as a list sorted by size in bytes
-# all - Build application and list size
-# lib - Build and archive source files into a library
-# elf - Build application ELF debug object file
-# bin - Build application BIN binary object file
-# hex - Build application HEX object file
-# lss - Build application LSS assembly listing file
-# clean - Remove all project intermediary and binary
-# output files
-# mostlyclean - Remove intermediary output files, but
-# preserve binaries
-# <filename>.s - Compile C/C++ source file into an assembly file
-# for manual code inspection
-#
-# MANDATORY PARAMETERS:
-#
-# TARGET - Application name
-# ARCH - Device architecture name
-# MCU - Microcontroller device model name
-# SRC - List of input source files (*.c, *.cpp, *.S)
-# F_USB - Speed of the input clock of the USB controller
-# in Hz
-# LUFA_PATH - Path to the LUFA library core
-#
-# OPTIONAL PARAMETERS:
-#
-# BOARD - LUFA board hardware
-# OPTIMIZATION - Optimization level
-# C_STANDARD - C Language Standard to use
-# CPP_STANDARD - C++ Language Standard to use
-# F_CPU - Speed of the CPU, in Hz
-# C_FLAGS - Flags to pass to the C compiler only
-# CPP_FLAGS - Flags to pass to the C++ compiler only
-# ASM_FLAGS - Flags to pass to the assembler only
-# CC_FLAGS - Common flags to pass to the C/C++ compiler and
-# assembler
-# LD_FLAGS - Flags to pass to the linker
-# LINKER_RELAXATIONS - Enable or disable linker relaxations to
-# decrease binary size (note: can cause link
-# failures on systems with an unpatched binutils)
-# OBJDIR - Directory for the output object and dependency
-# files; if equal to ".", the output files will
-# be generated in the same folder as the sources
-# OBJECT_FILES - Extra object files to link in to the binaries
-# DEBUG_FORMAT - Format of the debugging information to
-# generate in the compiled object files
-# DEBUG_LEVEL - Level the debugging information to generate in
-# the compiled object files
-# COMPILER_PATH - Location of the GCC toolchain to use
-#
-# PROVIDED VARIABLES:
-#
-# (None)
-#
-# PROVIDED MACROS:
-#
-# (None)
