SPIP is a publishing system for the Internet in which great importance is attached to collaborative working, to multilingual environments, and to simplicity of use for web authors. It consists of a collection of files installed on a web server which allow you to take advantage of a number of automated tasks: multi-user management, laying out your articles without the need to use HTML, easily modifying the structure of your site, etc. Using the very same application as used to browse a site (Netscape, Microsoft Internet Explorer, Mozilla, Opera...), SPIP enables you to build and update your site thanks to a very simple user interface.
