I have worked with Mojave framework for more than 1 year while i was in ECBBBD. This is a true MVC(Model View Controller) Framework.
With this framework its easy to develop any kind of site and web application. Smarty is intigrated with this framework.
The original project site can be found at http://www.mojavi.org
This site’s development is currently stopped. But you can have a brief idea there.
If you’re looking for the Mojavi 2.0 API Documentation it can now be found at http://www.tannerburson.com/docs/mojavi/api please update your bookmarks accordingly.
I have worked on many projects using this framework. Though its not that much famous framework, its simple and easy.
