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 + + 1. 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. + + 2. 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. + + 3. 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. + + 4. 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. -- cgit v1.2.3
