Locomotive CMS

Today, I found a really good CMS. I'm looking for ruby 3 CMS for a while. I found this CMS solution that use my favorite NoSQL database system: MongoDB. I think multi site feature is rare in ror applications. Locomotive CMS do it.

Locomotive is an open source CMS for Rails 3. It's super flexible and integrates with Heroku and Amazon

Some features from technical Specs:
My favorite point: MongoDB with Mongoid
I've already used in some project: Devise authentication solution. I think this is the best authentication gem.
HAML: HTML Abstraction Markup Language. I think SASS and HAML make easy html writing.
The following items were totally new for me:

• Liquid
  Safe, customer facing template language
• Formtastic
  Form builder with semantically rich / accessible markup
• InheritedResources
  Makes controllers more powerful and cleaner
• Carrierwave
  Classier solution for file uploads
• Jammit-S3
  Industrial Strength Asset Packaging

I try this awesome CMS and I will post about my experiences.
