Scriptabulous! - PHP Script Directory and Archive

Nexus is an open source, web-based, extensible document management system that you can install on your own host.Easy-to-use, simple to administrate and incredibly powerful, Nexus can centralize and bring order to your document library. Unlike X-Drive, Box.net and all the other hosted solutions Nexus gives you the power to deploy wherever you want leveraging existing hardware and technology. Nexus is built on cross-platform, open-source technology - it will run on any machine: Windows, Unix-variants, Macintosh, etc. as long as that machine has PHP 5 or later, MySQL 4 or later and any type of web server that supports server-side scripting (IIS or Apache, for example)
