For a cursory explanation and example of how it works and what it can do, just watch the movie, it’s about 10 mins.
If you want to help out with the project and/or download the nugget for installation got to the ABAPJS project page.
Big thanks to the Prototype, script.aculo.us and the Ruby on Rails developers as all this work simply follows in there sufficiently large footsteps.
This is only a beta version of the framework, most of it is done, however, some of the helpers are missing. If there is interest I ( or someone in the community, hint hint ) will finish the rest of the helper methods and the remaining script.aculo.us controls.
