Most of the code of KallistiOS proper is currently covered under the KOS License, which are the terms of the *new* BSD license with our names inserted as the copyright holders and the "advertising clause" removed entirely. In all files that state that they are part of the KallistiOS operating system, you can assume that the following text is inserted in the header: * * This program is free software; you can redistribute it and/or modify * it under the terms of the KOS License. * * This 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. See the * KOS License (README.KOS) for more details. * * You should have received a copy of the KOS License along with this * program; if not, please visit Cryptic Allusion Game Dev at: * * http://gamedev.allusion.net/ * The text of that license follows. In layman's terms, all it really says is that you have to give credit where credit is due (both in derived source files and binary compilations; a credit in the documentation is ok) and there is no warranty. Dan Potter Giving credit means giving credit to everyone involved. The AUTHORS file in the root directory of the KOS source tree is there to help. It should note all of the named contributors (those who have provided copyright notices in any files) to the KOS codebase, along with the years of their contributions. It's there to make it pretty easy to give credit where credit is due. :) Lawrence Sebald The actual license terms begin below this line: -------------------------------------------------------------------------------- All of the documentation and software included in the KallistiOS Releases is copyrighted (C) 1997-2016 by Dan Potter, Lawrence Sebald, and others (as noted in each file).
