Free and open source newspaper content management system

I came across ProsePoint - a Newspaper management system built on the top of Drupal.

This is what website says.
ProsePoint is a software package that lets you quickly and easily publish your own newspaper or magazine online. You can upload stories, edit stories online, and organise stories into editions, all through the user-friendly and convenient web interface. You do not need to know any programming or html.

ProsePoint aims to have as many commonly used features as possible available and ready to go out of the box. For a new publication, this means no customising or searching around for extra modules. If you find a theme you like, you don't even a web designer. Just install ProsePoint and you're ready to publish!
