+# -----------------------------------------------------------------------------
+# 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
+# check-source - Print a list of SRC source files that cannot
+# be found
+# all - Build application and list size
+# lib - Build and archive source files into a library
+# elf - Build application ELF debug object file
+# hex - Build application HEX object files
+# lss - Build application LSS assembly listing file
+# clean - Remove all project intermediatary and binary
+# output files
+# mostlyclean - Remove intermediatary output files, but
+# preserve binaries
+#
+# 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
+# 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
+#
+# PROVIDED VARIABLES:
+#
+# (None)
+#
+# PROVIDED MACROS:
+#
+# (None)
+#
