4# The include file <bsd.kmod.mk> handles installing Loadable Kernel Modules.
5# <bsd.kmod.mk> includes the file named "../Makefile.inc" if it exists,
6# as well as the include file <bsd.obj.mk>, <bsd.dep.mk>, and
7# may be <bsd.man.mk>
8#

10# +++ variables +++
11#
12# CLEANFILES	Additional files to remove for the clean and cleandir targets.
13#
14# DISTRIBUTION  Name of distribution. [bin]
15#
16# EXPORT_SYMS	???
17#
18# KERN		Main Kernel source directory. [${.CURDIR}/../../sys/kern]
19#
20# KMOD          The name of the loadable kernel module to build.
21#
22# KMODDIR	Base path for loadable kernel modules
23#		(see lkm(4)). [/lkm]
24#
25# KMODOWN	LKM owner. [${BINOWN}]
26#
27# KMODGRP	LKM group. [${BINGRP}]
28#
29# KMODMODE	LKM mode. [${BINMODE}]
30#
31# LINKS		The list of LKM links; should be full pathnames, the
32#               linked-to file coming first, followed by the linked
33#               file.  The files are hard-linked.  For example, to link
34#               /lkm/master and /lkm/meister, use:
35#
36#			LINKS=  /lkm/master /lkm/meister
37#
38# LN_FLAGS	Flags for ln(1) (see variable LINKS)
39#
40# MODLOAD	Command to load a kernel module [/sbin/modload]
41#
42# MODUNLOAD	Command to unload a kernel module [/sbin/modunload]
43#
44# NOMAN		LKM does not have a manual page if set.
45#
46# PROG          The name of the loadable kernel module to build. 
47#		If not supplied, ${KMOD}.o is used.
48#
49# PSEUDO_LKM	???
50#
51# SRCS          List of source files 
52#
53# SUBDIR        A list of subdirectories that should be built as well.
54#               Each of the targets will execute the same target in the
55#               subdirectories.
56#
57# DESTDIR, DISTDIR are set by other Makefiles (e.g. bsd.own.mk)

62#       distribute:
63#               This is a variant of install, which will
64#               put the stuff into the right "distribution".
65#
66# 	install:
67#               install the program and its manual pages; if the Makefile
68#               does not itself define the target install, the targets
69#               beforeinstall and afterinstall may also be used to cause
70#               actions immediately before and after the install target
71#		is executed.
72#
73# 	load:	
74#		Load LKM.
75#
76# 	tags:
77#		Create a tags file for the source files.
78#

80#		Unload LKM.
