+#		Prefix	Operation
+#		------	---------
+#		fast	Skip the pid check, and set rc_fast=yes
+#		force	Set ${rcvar} to YES, and set rc_force=yes
+#
+#	The following globals are used:
+#
+#	Name		Needed	Purpose
+#	----		------	-------
+#	name		y	Name of script.
+#
+#	command		n	Full path to command.
+#				Not needed if ${rc_arg}_cmd is set for
+#				each keyword.
+#
+#	command_args	n	Optional args/shell directives for command.
+#
+#	command_interpreter n	If not empty, command is interpreted, so
+#				call check_{pidfile,process}() appropriately.
+#
+#	extra_commands	n	List of extra commands supported.
+#
+#	pidfile		n	If set, use check_pidfile $pidfile $command,
+#				otherwise use check_process $command.
+#				In either case, only check if $command is set.
+#
+#	procname	n	Process name to check for instead of $command.
+#
+#	rcvar		n	This is checked with checkyesno to determine
+#				if the action should be run.
+#
+#	${name}_chroot	n	Directory to chroot to before running ${command}
+#				Requires /usr to be mounted.
+#
+#	${name}_chdir	n	Directory to cd to before running ${command}
+#				(if not using ${name}_chroot).
+#
+#	${name}_flags	n	Arguments to call ${command} with.
+#				NOTE:	$flags from the parent environment
+#					can be used to override this.
+#
+#	${name}_nice	n	Nice level to run ${command} at.
+#
+#	${name}_user	n	User to run ${command} as, using su(1) if not
+#				using ${name}_chroot.
+#				Requires /usr to be mounted.
+#
+#	${name}_group	n	Group to run chrooted ${command} as.

+#
+#	${name}_groups	n	Comma separated list of supplementary groups
+#				to run the chrooted ${command} with.
+#				Requires /usr to be mounted.
+#
+#	${name}_systrace n	Flags passed to systrace(1) if it is used.
+#				Setting this variable enables systracing
+# 				of the given program.  The use of "-a" is
+#				recommended so that the boot process is not
+#				stalled.  In order to pass no flags to
+#				systrace, set this variable to "--".
+#
+#	${rc_arg}_cmd	n	If set, use this as the method when invoked;
+#				Otherwise, use default command (see below)
+#
+#	${rc_arg}_precmd n	If set, run just before performing the
+#				${rc_arg}_cmd method in the default
+#				operation (i.e, after checking for required
+#				bits and process (non)existence).
+#				If this completes with a non-zero exit code,
+#				don't run ${rc_arg}_cmd.
+#
+#	${rc_arg}_postcmd n	If set, run just after performing the
+#				${rc_arg}_cmd method, if that method
+#				returned a zero exit code.
+#
+#	required_dirs	n	If set, check for the existence of the given
+#				directories before running the default
+#				(re)start command.
+#
+#	required_files	n	If set, check for the readability of the given
+#				files before running the default (re)start
+#				command.
+#
+#	required_vars	n	If set, perform checkyesno on each of the
+#				listed variables before running the default
+#				(re)start command.
+#
+#	Default behaviour for a given argument, if no override method is

+#			kill $sig_stop $rc_pid
+#			wait_for_pids $rc_pid
+#			($sig_stop defaults to TERM.)
+#
+#	reload		Similar to stop, except use $sig_reload instead,

+#			$sig_reload defaults to HUP.

+#	restart		Run `stop' then `start'.
