Crawl contains no code from + Nethack in any shape or form. + + Based on the NETHACK GENERAL PUBLIC LICENCE + (Copyright 1989 M. Stephenson) + + Based on the BISON GENERAL PUBLIC LICENCE + (Copyright 1988 Richard M. Stallman) + + Everyone is permitted to copy and distribute verbatim copies of + this licence, but changing it is not allowed. You can also use this + wording to make the terms for other programs. + + The licence agreements of most software companies keep you at the + mercy of those companies. By contrast, our general public licence + is intended to give everyone the right to share Crawl. 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 licence agreement. + + Specifically, we want to make sure that you have the right to give + away copies of Crawl, that you receive source code or else can get + it if you want it, that you can change Crawl 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 Crawl, 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 Crawl. If Crawl is modified + by someone else and passed on, we want its recipients to know that + what they have is not what we distributed. + + Therefore I (Linley Henzell, the copyright holder of Crawl) make + the following terms which say what you must do to be allowed to + distribute or change Crawl. + + COPYING POLICIES + + 1. You may copy and distribute verbatim copies of Crawl 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 Licence + Agreement, and to the absence of any warranty; and give any other + recipients of the Crawl program a copy of this Licence Agreement + along with the program. + 2. You may modify your copy or copies of Crawl or any portion of it, + and copy and distribute such modifications under the terms of + Paragraph 1 above (including distributing this Licence 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 Crawl + or any part thereof, to be licensed at no charge to all third + parties on terms identical to those contained in this Licence + 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 Crawl (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 available from my web site or updated + copies of the files in this distribution used to create the object + code or executable. + 4. You may not copy, sublicence, distribute or transfer Crawl except + as expressly provided under this Licence Agreement. Any attempt + otherwise to copy, sublicence, distribute or transfer Crawl is + void and your rights to use the program under this Licence + agreement shall be automatically terminated. However, parties who + have received computer software programs from you with this + Licence Agreement will not have their licences terminated so long + as such parties remain in full compliance. + + Stated plainly: You are prohibited by the terms of this Licence + Agreement from using Crawl for gainful purposes. You are permitted + to modify Crawl, or otherwise use parts of Crawl, provided that you + comply with the conditions specified above; in particular, your + modified Crawl or program containing parts of Crawl must remain + freely available as provided in this Licence Agreement. In other + words, go ahead and share Crawl, but don't try to stop anyone else + from sharing it farther. -- cgit v1.2.3-54-g00ecf
