+# Script for configuring a vif in routed 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-route (add|remove|online|offline)
+#
+# Environment vars:
+# vif vif interface name (required).
+# XENBUS_PATH path to this device's details in the XenStore (required).
+# Read from the store:
+# ip list of IP networks for the vif, space-separated (default given in
+# this script).
+# V6PREFIX prefix of v6 address to use
+# Note that the v6 support is kind of broken because there's not really a way to populate the v6 prefix
+# This script will set up proxy arp for any ip addresses that are being routed
+# type read to determine if the device is ioemu
