# examples of invoking this Makefile:
# make -fefm32-slstk3401a.mak  # make and run the tests in the current directory
# make -fefm32-slstk3401a.mak norun  # only make but not run the tests
# make -fefm32-slstk3401a.mak clean  # cleanup the build
#
# NOTE:
# To use this Makefile on Windows, you will need the GNU make utility, which
# is included in the Qtools collection for Windows, see:
