#
# very simple makefile (SunOS!)
#
# Possible defines:
# DEBUG_DCF:	include debug code (STREAMS mechanism and parsing)
# DEBUG_CD:	include signal propagation to sun4c LED (sun4c only)
#
# Possible defines (parsestreams variants only):
# KERNEL:	must define
# VDDRV:	loadable driver support - recommended
# KARCH:	must define at make call for correct kernel module
#               (currently only needed for parsestreams variants)
