# note on build targets
#
# module-assistant makes some assumptions about targets, namely
#  <modulename>: must be present and build the module <modulename>
#		<modulename>.ko is not enough
# install: must be present (and should only install the module)
#
# we therefore make <modulename> a .PHONY alias to <modulename>.ko
# and remove utils-installation from 'install'
# call 'make install-all' if you want to install everything
