Consider this version 0.1 - a preview, if you will. Some stuff that still needs to be done:\n\n* Proper racket-style packaging of the libraries\n* Better abstraction of functions for changing keys, using intelligent macros\n* Use other sound backends (rsound is currently the only one supported)\n* Provide options for changing instrumentation/timbre/etc.\n\n\nLicense\n--------\n\n*Play That Racket!* is free software licensed under version 3 of the GNU Affero General Public License, available in the COPYING file (also symlinked from LICENSE).\n\nCopyright (C) 2013 Aditya Mukerjee\n\nThis program is free software: you can redistribute it and/or modify it under the terms of the GNU Affero General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version.\n\nThis program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
