#
# The include file <bsd.kmod.mk> handles installing Loadable Kernel Modules.
# <bsd.kmod.mk> includes the file named "../Makefile.inc" if it exists,
# as well as the include file <bsd.obj.mk>, <bsd.dep.mk>, and
# may be <bsd.man.mk>
#
#
# +++ variables +++
#
# CLEANFILES Additional files to remove for the clean and cleandir targets.
#
# DISTRIBUTION Name of distribution. [bin]
#
# EXPORT_SYMS ???
#
# KERN Main Kernel source directory. [${.CURDIR}/../../sys/kern]
#
# KMOD The name of the loadable kernel module to build.
#
# KMODDIR Base path for loadable kernel modules
# (see lkm(4)). [/lkm]
#
# KMODOWN LKM owner. [${BINOWN}]
#
# KMODGRP LKM group. [${BINGRP}]
#
# KMODMODE LKM mode. [${BINMODE}]
#
# LINKS The list of LKM 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
# /lkm/master and /lkm/meister, use:
#
# LINKS= /lkm/master /lkm/meister
#
# LN_FLAGS Flags for ln(1) (see variable LINKS)
#
# NOMAN LKM does not have a manual page if set.
#
# PROG The name of the loadable kernel module to build.
# If not supplied, ${KMOD} is used.
#
# PSEUDO_LKM ???
#
# 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.
#
# DESTDIR, DISTDIR are set by other Makefiles (e.g. bsd.own.mk)
#
#
# +++ 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 LKM.
#
# tags:
# Create a tags file for the source files.
#
# unload:
# Unload LKM.
#
# bsd.obj.mk: clean, cleandir and obj
# bsd.dep.mk: depend
# bsd.man.mk: maninstall
