Alive CMS
Download Alive CMS here. Alive CMS is a Django project that does not need configuration as you might be used to, the only thing you might want to change are the DB settings in settings.py. By default it will use sqlite3 and to use another DB like MySQL, you need to change settings.py.
After unzipping the archive you need to create an admin user with the 'create_admin' program found inside the project directory. This will also set up user storage. Then you need to create an Alive CMS application, see the tutorials for details.
