Falt4 CMS
Falt4 is a web content management system designed for small to midrange websites. The whole system has been released under the LGPL (lesser GPL License) and is, so called, "free software". The system comes with a lot of modules and even more core features, which come in very handy for daily use. Falt4 is easy to use and has been tested during the developmentphase on a lot of customers, where some of them had no website experience at all. Also included is a lesser seen feature in OpenSource systems: Falt4 is Multilingual in every aspect - and this is just the beginning. Including a system wide media database to manage all your files, a template editor and an integrated publishing system with versioning support are just a few of the strong core features of falt4.
