+#
+# Version = 1.0.3
+# Date = 2007-09-14
+#
+# Maintainer(s) = Ron Terry - ron (at) pronetworkconsulting (dot) com
+#
+# The latest version can be found at:

+#    http://pronetworkconsulting.com/linux/scripts/xend-relocation.html
+#
+# Description:
+#
+# This script is used to enable or disable the VM relocation (migration)
+#  feature of xend.  It can be used to manage the local instance of xend
+#  or both the local instance and instances of xend on the other machines
+#  to/from which VMs can be relocated.
+# To manage the instances of xend on other machines this script communicates
+#  using ssh so it is recomended that if you use this feature you 
+#  pre-distribute ssh keys between the servers.
+#
+# Depends on:
+#
+# Can use:           /etc/sysconfig/xend
+#
+# Usage:             xend-relocation (start|stop|status)
+#                 or
+#                    xend-relocation (on|off|status)
+#
+# Vars:
+#
+#  XEN_CONFIG_FILE
+#
+#  RELOCATION_NODELIST
+#
+#  MANAGE_ALL_RELOCATION_NODES
+#
+#  XEN_RELOCATION_PORT
