4# The include file <bsd.kmod.mk> handles installing Kernel Loadable Device
5# drivers (KLD's).

10# CLEANFILES Additional files to remove for the clean and cleandir targets.
11#
12# KMOD The name of the kernel module to build.

24# KMODUNLOAD Command to unload a kernel module [/sbin/kldunload]
25#
26# NOMAN KLD does not have a manual page if set.
27#
28# PROG The name of the kernel module to build.
29# If not supplied, ${KMOD}.o is used.

38# This file contains a default list of interfaces.
39#
40# +++ targets +++
41#
42# install:
43# install the kernel module and its manual pages; if the Makefile
44# does not itself define the target install, the targets
45# beforeinstall and afterinstall may also be used to cause
46# actions immediately before and after the install target
47# is executed.

50# Load KLD.

53# Unload KLD.
