The section "Managing X.509 Certificates" is based on portions of the OpenVPN HOWTO (http://openvpn.net/howto.html), which is copyright (C) 2002-2005 by James Yonan and released under the GNU Free Documentation License.

Felipe Gasper helped with proofreading and offered suggestions for generalizing some aspects of the presentation, including the shell scripts.

I also owe a large debt to the members of the Gentoo Linux Forums (http://forums.gentoo.org/) for helping solve the niggling problems needed to make my own system work, and thus make this document possible.
