Gravey is a framework for developing Rich Internet Applications using standard design patterns like MVC, Command, AJAX, and REST.
It is distinct in being a completely stand-alone JavaScript library, hence it does not depend on any particular client or server frameworks or technologies (e.g. J2EE, .Net, jQuery, etc).
It is also unique in providing a framework for arbitrarily deep levels of undo/redo commands.
