operating systems.
+=item B<Interface> I<Interface name>
+
+Set the outgoing or incoming interface for IP packets. This applies at least
+to IPv6 packets and if possible to IPv4. If this option is not applicable,
+undefined or a non-existent interface name is specified, the default
+behaviour is to let the kernel choose the appropriate interface. Be warned
+that the manual selection of an interface for unicast traffic is only
+necessary in rare cases.

Sets how the values are cumulated. I<Type> is one of:
the identifier of a value. If multiple regular expressions are given, B<all>
regexen must match for a value to match.

+
+When set to B<true>, the result of the match is inverted, i.e. all value lists
+where all regular expressions apply are not matched, all other value lists are
+matched. Defaults to B<false>.
