PHP-Nuke is a content management system written in PHP. It is currently available under
the GNU/GPL licence as a free download, but there are plans for a commercial licence
without the copyright information becoming available in the near future.
It is designed to be a flexible way of people to organise their web sites, including user
management, news, forums, reviews, and many more features, all organised and
administered through a centralised administration system.
In laymen's terms - it's a fancy way of controlling what's on your site
