#               LUFA Sources Buildsystem Makefile Module.
# -----------------------------------------------------------------------------
# DESCRIPTION:
#   Provides a set of makefile variables for the various LUFA module sources.
#   Once included, the sources required to use a given LUFA module will become
#   available using the makefile variable names listed in the LUFA project
#   documentation.
# -----------------------------------------------------------------------------
# TARGETS:
#
#    (None)
#
# MANDATORY PARAMETERS:
#
#    LUFA_PATH                 - Path to the LUFA library core
#    ARCH                      - Device architecture name
#
# OPTIONAL PARAMETERS:
#
#    (None)
#
# PROVIDED VARIABLES:
#
#    LUFA_SRC_USB              - List of LUFA USB driver source files
#    LUFA_SRC_USBCLASS         - List of LUFA USB Class driver source files
#    LUFA_SRC_TEMPERATURE      - List of LUFA temperature sensor driver source
#                                files
#    LUFA_SRC_SERIAL           - List of LUFA Serial U(S)ART driver source files
