	Usage:
	  $PROGNAME [-hV] [-t timeout] [-w savefile] {[rulesfile]|-c [runcmd]}

The script will try to apply a new rulesfile (as output by iptables-save,
	read by iptables-restore) or run a command to configure iptables and then
	prompt the user whether the changes are okay. If the new iptables rules cut
	the existing connection, the user will not be able to answer affirmatively.
	In this case, the script rolls back to the previous working iptables rules
	after the timeout expires.

Successfully applied rules can also be written to savefile and later used
	to roll back to this state. This can be used to implement a store last good
	configuration mechanism when experimenting with an iptables setup script:
	  $PROGNAME -w $DEF_SAVEFILE -c $DEF_RUNCMD

When called as ip6tables-apply, the script will use ip6tables-save/-restore
	and IPv6 default values instead. Default value for rulesfile is
	'$DEF_RULESFILE'.

Options:

-t seconds, --timeout seconds
	  Specify the timeout in seconds (default: $DEF_TIMEOUT).
	-w savefile, --write savefile
	  Specify the savefile where successfully applied rules will be written to
	  (default if empty string is given: $DEF_SAVEFILE).
	-c runcmd, --command runcmd
	  Run command runcmd to configure iptables instead of applying a rulesfile
	  (default: $DEF_RUNCMD).
	-h, --help
	  Display this help text.
	-V, --version
	  Display version information.
