The Layout page has been updated with a fairly detailed description of how YourOtherMind Layouts work.
Also, initial compiled versions of the software are deployed. These are untested, so use at your own risk (I just wanted to get the deploy framework put into place). Also, I am aiming to release the source code by mid-May.
Please keep in mind that this software is not supported! If you start using it, you do so at your own risk.
