+
+# PURPOSE: This script automatically removes the /etc/resolv.conf entries previously
+# set by the companion script "client.up".
+
+# INSTALL NOTES:
+# Place this in /etc/openvpn/client.down
+# Then, add the following to your /etc/openvpn/<clientconfig>.conf:
+#   client
+#   up /etc/openvpn/client.up
+#   down /etc/openvpn/client.down
+# Next, "chmod a+x /etc/openvpn/client.down"
+
+# USAGE NOTES:
+# Note that this script is best served with the companion "client.up"
+# script.
+
+# Tested under Debian lenny with OpenVPN 2.1_rc11
+# It should work with any UNIX with a POSIX sh, /etc/resolv.conf or resolvconf
+
+# This runs with the context of the OpenVPN UID/GID 
+# at the time of execution. This generally means that
+# the client "up" script will run fine, but the "down" script
+# will require the use of the OpenVPN "down-root" plugin
+# which is in the plugins/ directory of the OpenVPN source tree
+
+# A horrid work around, from a security perspective,
+# is to run OpenVPN as root. THIS IS NOT RECOMMENDED. You have
+# been WARNED.
