-# OpenVPN road warrior installer for Debian, Ubuntu and CentOS
-
-# This script will work on Debian, Ubuntu, CentOS and probably other distros
-# of the same families, although no support is offered for them. It isn't
-# bulletproof but it will probably work if you simply want to setup a VPN on
-# your Debian/Ubuntu/CentOS box. It has been designed to be as unobtrusive and
-# universal as possible.
