d-mapper is the start of dungeon map drawing and viewing tool.
It is currently built on HTML5 Boilerplate, jQuery, jQuery UI, Class.js, es5-shim, and Raphael.
All existing code is available under its original license. New code is available under the terms of GNU GPL v3.
For the love of god, please don't look at the code yet. In an attempt to bootstrap this quickly it has been thrown together incredibly quickly and sloppily. Once core functionality has been added the code will be cleaned up and refactored into something a bit more sane.
