Payago is a lightweight content management system written in Python, designed for easy maintenance of web sites containing both static and dynamic content. It uses Nevow, a templating and rendering engine for web applications, which is in turn built using the Twisted framework.

Payago has not been released, and it probably won't. The days when I had free time to work on reinventing the CMS wheel, just to satisfy my own interest in the problem, are long gone. However, if you still want to check out the current version from SVN, you can get it at:
