Stephenson) +(Based on the BISON general public license, copyright 1988 Richard M. Stallman) + +Everyone is permitted to copy and distribute verbatim copies of this license, +but changing it is not allowed. You can also use this wording to make the terms +for other programs. +The license agreements of most software companies keep you at the mercy of +those companies. By contrast, our general public license is intended to give +everyone the right to share NetHack. To make sure that you get the rights we +want you to have, we need to make restrictions that forbid anyone to deny you +these rights or to ask you to surrender the rights. Hence this license +agreement. + +Specifically, we want to make sure that you have the right to give away copies +of NetHack, that you receive source code or else can get it if you want it, +that you can change NetHack or use pieces of it in new free programs, and that +you know you can do these things. + +To make sure that everyone has such rights, we have to forbid you to deprive +anyone else of these rights. For example, if you distribute copies of NetHack, +you must give the recipients all the rights that you have. You must make sure +that they, too, receive or can get the source code. And you must tell them +their rights. + +Also, for our own protection, we must make certain that everyone finds out that +there is no warranty for NetHack. If NetHack is modified by someone else and +passed on, we want its recipients to know that what they have is not what we +distributed. + +Therefore we (Mike Stephenson and other holders of NetHack copyrights) make the +following terms which say what you must do to be allowed to distribute or +change NetHack. + +COPYING POLICIES + +You may copy and distribute verbatim copies of NetHack source code as you +receive it, in any medium, provided that you keep intact the notices on all +files that refer to copyrights, to this License Agreement, and to the absence +of any warranty; and give any other recipients of the NetHack program a copy of +this License Agreement along with the program. +You may modify your copy or copies of NetHack or any portion of it, and copy +and distribute such modifications under the terms of Paragraph 1 above +(including distributing this License Agreement), provided that you also do the +following: +a) cause the modified files to carry prominent notices stating that you changed +the files and the date of any change; and + +b) cause the whole of any work that you distribute or publish, that in whole or +in part contains or is a derivative of NetHack or any part thereof, to be +licensed at no charge to all third parties on terms identical to those +contained in this License Agreement (except that you may choose to grant more +extensive warranty protection to some or all third parties, at your option) + +c) You may charge a distribution fee for the physical act of transferring a +copy, and you may at your option offer warranty protection in exchange for a +fee. + +You may copy and distribute NetHack (or a portion or derivative of it, under +Paragraph 2) in object code or executable form under the terms of Paragraphs 1 +and 2 above provided that you also do one of the following: +a) accompany it with the complete machine-readable source code, which must be +distributed under the terms of Paragraphs 1 and 2 above; or, + +b) accompany it with full information as to how to obtain the complete machine- +readable source code from an appropriate archive site. (This alternative is +allowed only for noncommercial distribution.) + +For these purposes, complete source code means either the full source +distribution as originally released over Usenet or updated copies of the files +in this distribution used to create the object code or executable. + +You may not copy, sublicense, distribute or transfer NetHack except as +expressly provided under this License Agreement. Any attempt otherwise to copy, +sublicense, distribute or transfer NetHack is void and your rights to use the +program under this License agreement shall be automatically terminated. +However, parties who have received computer software programs from you with +this License Agreement will not have their licenses terminated so long as such +parties remain in full compliance. +Stated plainly: You are permitted to modify NetHack, or otherwise use parts of +NetHack, provided that you comply with the conditions specified above; in +particular, your modified NetHack or program containing parts of NetHack must +remain freely available as provided in this License Agreement. In other words, +go ahead and share NetHack, but don't try to stop anyone else from sharing it +farther. +[ Home | Version 3.4.3 | Contact Us ] + + + +Hosted by: +NetHack is Copyright 1985-2003 by Stichting Mathematisch Centrum and M. +Stephenson.
