+#!/bin/bash
+
+# This is a RackTables gateway for changing switch ports membership
+# across VLANs. It works accordingly to the gateway protocol described
+# in gateways.php and accepts the following commands on its stdin:
+# * listvlans: list all VLANs found on the switch, propably filtering
+# out those administratively prohibited. Only the VLANs from this
+# list will be allowed as new destination for 'set' command.
+# * listports: list all ports on the switch and their current status.
+# Untagged (switchport mode access) ports will be shown with their
+# VLAN ID and tagged ports will be shown as 'trunk' regardless of
+# how many VLANs they are members of.
