action = accept | reject | deny
target = ip | ip/cidr | "client_ip"
rule = <action> <target> | "default" <action>


It works like a firewall : you define a set of hosts you want/don't want
to scan, and you finish your statement with a default policy.

The order of the policies is :

	nessusd.rules
	$prefix/var/nessus/users/<login>/auth/rules

And then the user can restrict his scope thru the GTK client.
Once a scope has been defined in nessusd.rules, it can only be reduced
furthermore, not be expanded.
