>Description:
	The ipfw(8) manpage has an example of using ipfw sets of rules,
        but the example does not work.

	Try to execute commands from EXAMPLES/SETS OF RULES manpage section

	# id
	uid=0(root) gid=0(wheel) groups=0(wheel), 5(operator)
        # ipfw disable set 18
        ipfw: unrecognize enable/disable keyword: set

	 .Ss SETS OF RULES
	 To add a set of rules atomically, e.g. set 18:
	 .Pp
	-.Dl "ipfw disable set 18"

	-.Dl "ipfw enable set 18"
	+.Dl "ipfw set enable 18"
	 .Pp
	 To delete a set of rules atomically the command is simply:
	 .Pp
	_at__at_ -2011,9 +2011,9 _at__at_
	 .Pp
	 To test a ruleset and disable it and regain control if something goes wrong:
	 .Pp
	-.Dl "ipfw disable set 18"
	+.Dl "ipfw set disable 18"
	 .Dl "ipfw add NN set 18 ...         # repeat as needed"
	-.Dl "ipfw enable set 18 ; echo done; sleep 30 && ipfw disable set 18"
	+.Dl "ipfw set enable 18 ; echo done; sleep 30 && ipfw set disable 18"
	 .Pp
	 Here if everything goes well, you press control-C before the "sleep"
	 terminates, and your ruleset will be left active. Otherwise, e.g. if
