#	From: @(#)bsd.prog.mk	5.26 (Berkeley) 6/25/91
# $FreeBSD$
#
# 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.
#
# DISTRIBUTION  Name of distribution. [bin]
#
# KMOD          The name of the kernel module to build.
#
# KMODDIR	Base path for kernel modules (see kld(4)). [/boot/kernel]
#
# KMODOWN	KLD owner. [${BINOWN}]
#
# KMODGRP	KLD group. [${BINGRP}]
#
# KMODMODE	KLD mode. [${BINMODE}]
#
# LINKS		The list of KLD links; should be full pathnames, the
#               linked-to file coming first, followed by the linked
#               file.  The files are hard-linked.  For example, to link
#               /modules/master and /modules/meister, use:
#
#			LINKS=  /modules/master /modules/meister
#
# 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
#
# SUBDIR        A list of subdirectories that should be built as well.
#               Each of the targets will execute the same target in the
#               subdirectories.
#
# SYMLINKS	Same as LINKS, except it creates symlinks and the
#		linked-to pathname may be relative.
#
# DESTDIR, DISTDIR are set by other Makefiles (e.g. bsd.own.mk)
#
# MFILES	Optionally a list of interfaces used by the module.
#		This file contains a default list of interfaces.
#
# +++ targets +++
#
#       distribute:
#               This is a variant of install, which will
#               put the stuff into the right "distribution".
#
# 	install:
#               install the program 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
#
