For more information on Owl, please refer to its homepage at:

In particular, please be aware that currently the installation procedure requires Linux system administration experience. If you're used to specifying a custom Linux kernel configuration for each box then Owl is just for you!
<p>
Owl is free software, both in the sense of freedom (http://www.gnu.org/philosophy/free-sw.html) and price.<br>
You are, however, encouraged to buy Owl on CD which saves you the download time and supports the project.<br>
You may also order remote installation of Owl (you just boot off the CD, we do the rest), commercial support and/or donate money to support future work on Owl and related community activities.
