+For OpenVPN to work as a server, you will need to do the following:
+
+1) Create configuration file in #{etc}/openvpn, samples can be
+   found in #{share}/doc/openvpn
+
+2) Install the launchd item in /Library/LaunchDaemons, like so:
+
+   sudo cp -vf #{prefix}/org.openvpn.plist /Library/LaunchDaemons/.
+   sudo chown -v root:wheel /Library/LaunchDaemons/org.openvpn.plist
+
+3) Start the daemon using:
+
+   sudo launchctl load /Library/LaunchDaemons/org.openvpn.plist
+
+Next boot of system will automatically start OpenVPN.
