update : 23/12/2020 DotClear

Dotclear is an open source web publishing solution created in 2002 by Olivier Meunier. Dotclear’s software was designed first and foremost for its users, who regularly contribute to its development. In June 2009, Xavier Plantefève took over the project.

Dotclear's functional depth makes it a high quality publishing tool, equal and in some cases far superior to other tools of the same type. Over and above its functionalities, Dotclear was designed for maximum user comfort, with its two step automated installation. In addition, many themes and plug-ins are available for easy personalisation. It generates pages with a structure that optimises their natural referencing.
Dotclear is distributed under the GPL v2.
It is developed in PHP and supports PostgreSQL (8.0 and above), MySQL (at least 4.1 with InnoDB) and SQLite databases.
