-#
-# Script for configuring a vif in routed-nat mode.
-# The hotplugging system will call this script if it is specified either in
-# the device configuration given to Xend, or the default Xend configuration
-# in /etc/xen/xend-config.sxp.  If the script is specified in neither of those
-# places, then vif-bridge is the default.
-#
-# Usage:
-# vif-nat (add|remove|online|offline)
-#
-# Environment vars:
-# vif         vif interface name (required).
-# XENBUS_PATH path to this device's details in the XenStore (required).
-#
-# Parameters:
-# dhcp        Whether to alter the local DHCP configuration to include this
-#             new host (default no).
-#
-# Read from the store:
-# ip      list of IP networks for the vif, space-separated (default given in
-#         this script).
