+If no configuration if given, the B<iwinfo>-plugin will collect data from all
+detected wireless interfaces. You can use the B<Interface>-option to pick the
+interfaces you're interested in. Sometimes, however, it's easier/preferred to
+collect all interfaces I<except> a few ones. This option enables you to do
+that: By setting B<IgnoreSelected> to I<true> the effect of B<Interface> is
+inverted: All selected interfaces are ignored and all other interfaces are
