Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions:
The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.
THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT. IN NO EVENT SHALL THE AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN AN ACTION OF CONTRACT, TORT OR OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION WITH THE SOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE.
By using the Software, you acknowledge that the author(s) want you to use the Software to do something positive in the world, such as advancing creative coding and signal processing, and that the author(s) wish that any of your deeds, good or bad, done in relation to the Software, shall reflect back on you tenfold. As an example, should you use the Software to help realize an art project, the author(s) wish that you shall get ten times as much help as a result. However, should you use the Software to make products designed to harm people, and even just one innocent person is being harmed by those products, the author(s) wish from the bottom of their hearts that you and all those who directed or commissioned the actions causing the harm be harmed in the same way ten times over. "Innocent" shall be defined using common sense and "person" isn't even up for definition. You do NOT get to define en entire population, religion, or ethnicity as guilty, and you DEFINITELY DO NOT get to define who is human and who is not. If you feel called out now, please reconsider your life choices. Also, if you have read the license all the way up to here and you believe that wiping out an entire civilization is a good thing, please do NOT use the Software, as your morals are clearly not compatible with the spirit of this agreement.
