Aether is a wiki-esque CGI script for creating and editing Web pages and Weblogs via a Web interface. It consists of a single easy-to-install script and uses a simple markup language to lay out pages. Unicode is supported in both page text and URLs. It can produce Atom syndication feeds for each Weblog in a site. A simple revision tracking system allows previous versions of a page to be restored.
