Hi all, I just released the new version of my CMS AdminPages as a Rails
engine.
It uses the Dojo Toolkit for UI elements.
Features:
Manipulate pages and content with Drag n Drop,
Pages in a sortable tree,
easy to define new page elements,
“Nice” URLs,
Page Caching,
Rich Text Editor,
multiple columns per page,
custom content types,
Layout scaffolding
BSD license
(…)
There’s a running demo at http://adminpages.flowdev.de
The server is pretty bad, so expect downtimes.
Here’s a screenshot:

The project homepage is http://rubyforge.org/projects/adminpages
Download:
http://rubyforge.org/frs/download.php/9541/admin_pages_engine_0.2.0.tar.gz
A whopping 37 kb! 
It should run under recent IE and firefox versions, I did not yet test
with Safari or Opera. The tree does not appear under Konqueror, I’m sure
it will work in the future.
So if you like the system, you are very welcome to contribute! We need
more page elements, and of course a lot of testing.
Documentation is in the README file included in the package.
