3#
4# The include file <bsd.kmod.mk> handles installing Kernel Loadable Device
5# drivers (KLD's).
6#
7#
8# +++ variables +++
9#
10# CLEANFILES	Additional files to remove for the clean and cleandir targets.
11#
12# DISTRIBUTION  Name of distribution. [bin]
13#
14# KERN		Main Kernel source directory. [${.CURDIR}/../../sys/kern]
15#
16# KMOD          The name of the kernel module to build.
17#
18# KMODDIR	Base path for kernel modules (see kld(4)). [/modules]
19#
20# KMODOWN	KLD owner. [${BINOWN}]
21#
22# KMODGRP	KLD group. [${BINGRP}]
23#
24# KMODMODE	KLD mode. [${BINMODE}]
25#
26# LINKS		The list of KLD links; should be full pathnames, the
27#               linked-to file coming first, followed by the linked
28#               file.  The files are hard-linked.  For example, to link
29#               /modules/master and /modules/meister, use:
30#
31#			LINKS=  /modules/master /modules/meister
32#
33# KMODLOAD	Command to load a kernel module [/sbin/kldload]
34#
35# KMODUNLOAD	Command to unload a kernel module [/sbin/kldunload]
36#
37# NOMAN		KLD does not have a manual page if set.
38#
39# PROG          The name of the kernel module to build. 
40#		If not supplied, ${KMOD}.o is used.
41#
42# SRCS          List of source files 
43#
44# KMODDEPS	List of modules which this one is dependant on
45#
46# SUBDIR        A list of subdirectories that should be built as well.
47#               Each of the targets will execute the same target in the
48#               subdirectories.
49#
50# SYMLINKS	Same as LINKS, except it creates symlinks and the
51#		linked-to pathname may be relative.
52#
53# DESTDIR, DISTDIR are set by other Makefiles (e.g. bsd.own.mk)
54#
55#

57#
58#       distribute:
59#               This is a variant of install, which will
60#               put the stuff into the right "distribution".
61#
62# 	install:
63#               install the program and its manual pages; if the Makefile
64#               does not itself define the target install, the targets
65#               beforeinstall and afterinstall may also be used to cause
66#               actions immediately before and after the install target
67#		is executed.
68#
69# 	load:	
70#		Load KLD.
71#
72# 	unload:
73#		Unload KLD.
74#
75# bsd.obj.mk: clean, cleandir and obj
76# bsd.dep.mk: cleandepend, depend and tags
