What is "textpattern"

Textpattern is an open source content management system originally developed by Dean Allen. While it is often listed among weblogging tools, its aim is to be a general-purpose content management system suitable for deployment in many contexts. Textpattern is written in PHP using a MySQL database backend. Unlike many other CMS, Textpattern does not support any other database servers. The current stable version is Textpattern 4.5.7.
