# The include file <bsd.kmod.mk> handles installing Kernel Loadable Device
# drivers (KLD's).
#
#
# +++ variables +++
#
# CLEANFILES	Additional files to remove for the clean and cleandir targets.
#
# KMOD          The name of the kernel module to build.
#
# KMODDIR	Base path for kernel modules (see kld(4)). [/modules]
#
# KMODOWN	KLD owner. [${BINOWN}]
#
# KMODGRP	KLD group. [${BINGRP}]
#
# KMODMODE	KLD mode. [${BINMODE}]
#
# KMODLOAD	Command to load a kernel module [/sbin/kldload]
#
# KMODUNLOAD	Command to unload a kernel module [/sbin/kldunload]
#
# NOMAN		KLD does not have a manual page if set.
#
# PROG          The name of the kernel module to build.
#		If not supplied, ${KMOD}.o is used.
#
# SRCS          List of source files
#
# KMODDEPS	List of modules which this one is dependant on
#
# DESTDIR	Change the tree where the module gets installed. [not set]
#
# MFILES	Optionally a list of interfaces used by the module.
#		This file contains a default list of interfaces.
#
# +++ targets +++
#
# 	install:
#               install the kernel module and its manual pages; if the Makefile
#               does not itself define the target install, the targets
#               beforeinstall and afterinstall may also be used to cause
#               actions immediately before and after the install target
#		is executed.
#
# 	load:
#		Load KLD.
#
# 	unload:
#		Unload KLD.
#
# bsd.obj.mk: clean, cleandir and obj
# bsd.dep.mk: cleandepend, depend and tags
# bsd.man.mk: maninstall
