				# PROVIDE: openvpn
				# REQUIRE: DAEMON
				# KEYWORD: shutdown

				# -----------------------------------------------------------------------------
				#
				# This script supports running multiple instances of openvpn.
				# To run additional instances link this script to something like
				# % ln -s openvpn openvpn_foo
				# and define additional openvpn_foo_* variables in one of
				# /etc/rc.conf, /etc/rc.conf.local or /etc/rc.conf.d/openvpn_foo
				#
				# Below NAME should be substituted with the name of this script. By default
				# it is openvpn, so read as openvpn_enable. If you linked the script to
				# openvpn_foo, then read as openvpn_foo_enable etc.
				#
				# The following variables are supported (defaults are shown).
				# You can place them in any of
				# /etc/rc.conf, /etc/rc.conf.local or /etc/rc.conf.d/NAME
				#
				# NAME_enable="NO" # set to YES to enable openvpn
				# NAME_if= # driver(s) to load, set to "tun", "tap" or "tun tap"
				# # it is OK to specify the if_ prefix.
				#
				# # optional:
				# NAME_flags= # additional command line arguments
				# NAME_configfile="%%PREFIX%%/etc/openvpn/NAME.conf" # --config file
				# NAME_dir="%%PREFIX%%/etc/openvpn" # --cd directory
				#
				# You also need to set NAME_configfile and NAME_dir, if the configuration
				# file and directory where keys and certificates reside differ from the above
				# settings.
				#
				# Note that we deliberately refrain from unloading drivers.
				#
				# For further documentation, please see openvpn(8).
