18: Everyone is permitted to copy and distribute verbatim copies
19: of this license document, but changing it is not allowed.
20:
21: Preamble
22:
23: The licenses for most software are designed to take away your
24: freedom to share and change it. By contrast, the GNU General Public
25: License is intended to guarantee your freedom to share and change free
26: software--to make sure the software is free for all its users. This
27: General Public License applies to most of the Free Software
28: Foundation's software and to any other program whose authors commit to
29: using it. (Some other Free Software Foundation software is covered by
30: the GNU Library General Public License instead.) You can apply it to
31: your programs, too.
32:
33: When we speak of free software, we are referring to freedom, not
34: price. Our General Public Licenses are designed to make sure that you
35: have the freedom to distribute copies of free software (and charge for
36: this service if you wish), that you receive source code or can get it
37: if you want it, that you can change the software or use pieces of it
38: in new free programs; and that you know you can do these things.
39:
40: To protect your rights, we need to make restrictions that forbid
41: anyone to deny you these rights or to ask you to surrender the rights.
42: These restrictions translate to certain responsibilities for you if you
43: distribute copies of the software, or if you modify it.
44:
45: For example, if you distribute copies of such a program, whether
46: gratis or for a fee, you must give the recipients all the rights that
47: you have. You must make sure that they, too, receive or can get the
48: source code. And you must show them these terms so they know their
49: rights.
50:
51: We protect your rights with two steps: (1) copyright the software, and
52: (2) offer you this license which gives you legal permission to copy,
53: distribute and/or modify the software.
54:
55: Also, for each author's protection and ours, we want to make certain
56: that everyone understands that there is no warranty for this free
57: software. If the software is modified by someone else and passed on, we
58: want its recipients to know that what they have is not the original, so
59: that any problems introduced by others will not reflect on the original
60: authors' reputations.
61:
62: Finally, any free program is threatened constantly by software
63: patents. We wish to avoid the danger that redistributors of a free
64: program will individually obtain patent licenses, in effect making the
65: program proprietary. To prevent this, we have made it clear that any
66: patent must be licensed for everyone's free use or not licensed at all.
67:
68: The precise terms and conditions for copying, distribution and
69: modification follow.
70:
71: GNU GENERAL PUBLIC LICENSE
72: TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
73:
74: 0. This License applies to any program or other work which contains
75: a notice placed by the copyright holder saying it may be distributed
76: under the terms of this General Public License. The "Program", below,
77: refers to any such program or work, and a "work based on the Program"
78: means either the Program or any derivative work under copyright law:
79: that is to say, a work containing the Program or a portion of it,
80: either verbatim or with modifications and/or translated into another
81: language. (Hereinafter, translation is included without limitation in
82: the term "modification".) Each licensee is addressed as "you".
83:
84: Activities other than copying, distribution and modification are not
85: covered by this License; they are outside its scope. The act of
86: running the Program is not restricted, and the output from the Program
87: is covered only if its contents constitute a work based on the
88: Program (independent of having been made by running the Program).
89: Whether that is true depends on what the Program does.
90:
91: 1. You may copy and distribute verbatim copies of the Program's
92: source code as you receive it, in any medium, provided that you
93: conspicuously and appropriately publish on each copy an appropriate
94: copyright notice and disclaimer of warranty; keep intact all the
95: notices that refer to this License and to the absence of any warranty;
96: and give any other recipients of the Program a copy of this License
97: along with the Program.
98:
99: You may charge a fee for the physical act of transferring a copy, and
100: you may at your option offer warranty protection in exchange for a fee.
101:
102: 2. You may modify your copy or copies of the Program or any portion
103: of it, thus forming a work based on the Program, and copy and
104: distribute such modifications or work under the terms of Section 1
105: above, provided that you also meet all of these conditions:
106:
107: a) You must cause the modified files to carry prominent notices
108: stating that you changed the files and the date of any change.
109:
110: b) You must cause any work that you distribute or publish, that in
111: whole or in part contains or is derived from the Program or any
112: part thereof, to be licensed as a whole at no charge to all third
113: parties under the terms of this License.
114:
115: c) If the modified program normally reads commands interactively
116: when run, you must cause it, when started running for such
117: interactive use in the most ordinary way, to print or display an
118: announcement including an appropriate copyright notice and a
119: notice that there is no warranty (or else, saying that you provide
120: a warranty) and that users may redistribute the program under
121: these conditions, and telling the user how to view a copy of this
122: License. (Exception: if the Program itself is interactive but
123: does not normally print such an announcement, your work based on
124: the Program is not required to print an announcement.)
125:
126: These requirements apply to the modified work as a whole. If
127: identifiable sections of that work are not derived from the Program,
128: and can be reasonably considered independent and separate works in
129: themselves, then this License, and its terms, do not apply to those
130: sections when you distribute them as separate works. But when you
131: distribute the same sections as part of a whole which is a work based
132: on the Program, the distribution of the whole must be on the terms of
133: this License, whose permissions for other licensees extend to the
134: entire whole, and thus to each and every part regardless of who wrote it.
135:
136: Thus, it is not the intent of this section to claim rights or contest
137: your rights to work written entirely by you; rather, the intent is to
138: exercise the right to control the distribution of derivative or
139: collective works based on the Program.
140:
141: In addition, mere aggregation of another work not based on the Program
142: with the Program (or with a work based on the Program) on a volume of
143: a storage or distribution medium does not bring the other work under
144: the scope of this License.
145:
146: 3. You may copy and distribute the Program (or a work based on it,
147: under Section 2) in object code or executable form under the terms of
148: Sections 1 and 2 above provided that you also do one of the following:
149:
150: a) Accompany it with the complete corresponding machine-readable
151: source code, which must be distributed under the terms of Sections
152: 1 and 2 above on a medium customarily used for software interchange; or,
153:
154: b) Accompany it with a written offer, valid for at least three
155: years, to give any third party, for a charge no more than your
156: cost of physically performing source distribution, a complete
157: machine-readable copy of the corresponding source code, to be
158: distributed under the terms of Sections 1 and 2 above on a medium
159: customarily used for software interchange; or,
160:
161: c) Accompany it with the information you received as to the offer
162: to distribute corresponding source code. (This alternative is
163: allowed only for noncommercial distribution and only if you
164: received the program in object code or executable form with such
165: an offer, in accord with Subsection b above.)
166:
167: The source code for a work means the preferred form of the work for
168: making modifications to it. For an executable work, complete source
169: code means all the source code for all modules it contains, plus any
170: associated interface definition files, plus the scripts used to
171: control compilation and installation of the executable. However, as a
172: special exception, the source code distributed need not include
173: anything that is normally distributed (in either source or binary
174: form) with the major components (compiler, kernel, and so on) of the
175: operating system on which the executable runs, unless that component
176: itself accompanies the executable.
177:
178: If distribution of executable or object code is made by offering
179: access to copy from a designated place, then offering equivalent
180: access to copy the source code from the same place counts as
181: distribution of the source code, even though third parties are not
182: compelled to copy the source along with the object code.
183:
184: 4. You may not copy, modify, sublicense, or distribute the Program
185: except as expressly provided under this License. Any attempt
186: otherwise to copy, modify, sublicense or distribute the Program is
187: void, and will automatically terminate your rights under this License.
188: However, parties who have received copies, or rights, from you under
189: this License will not have their licenses terminated so long as such
190: parties remain in full compliance.
191:
192: 5. You are not required to accept this License, since you have not
193: signed it. However, nothing else grants you permission to modify or
194: distribute the Program or its derivative works. These actions are
195: prohibited by law if you do not accept this License. Therefore, by
196: modifying or distributing the Program (or any work based on the
197: Program), you indicate your acceptance of this License to do so, and
198: all its terms and conditions for copying, distributing or modifying
199: the Program or works based on it.
200:
201: 6. Each time you redistribute the Program (or any work based on the
202: Program), the recipient automatically receives a license from the
203: original licensor to copy, distribute or modify the Program subject to
204: these terms and conditions. You may not impose any further
205: restrictions on the recipients' exercise of the rights granted herein.
206: You are not responsible for enforcing compliance by third parties to
207: this License.
208:
209: 7. If, as a consequence of a court judgment or allegation of patent
210: infringement or for any other reason (not limited to patent issues),
211: conditions are imposed on you (whether by court order, agreement or
212: otherwise) that contradict the conditions of this License, they do not
213: excuse you from the conditions of this License. If you cannot
214: distribute so as to satisfy simultaneously your obligations under this
215: License and any other pertinent obligations, then as a consequence you
216: may not distribute the Program at all. For example, if a patent
217: license would not permit royalty-free redistribution of the Program by
218: all those who receive copies directly or indirectly through you, then
219: the only way you could satisfy both it and this License would be to
220: refrain entirely from distribution of the Program.
221:
222: If any portion of this section is held invalid or unenforceable under
223: any particular circumstance, the balance of the section is intended to
224: apply and the section as a whole is intended to apply in other
225: circumstances.
226:
227: It is not the purpose of this section to induce you to infringe any
228: patents or other property right claims or to contest validity of any
229: such claims; this section has the sole purpose of protecting the
230: integrity of the free software distribution system, which is
231: implemented by public license practices. Many people have made
232: generous contributions to the wide range of software distributed
233: through that system in reliance on consistent application of that
234: system; it is up to the author/donor to decide if he or she is willing
235: to distribute software through any other system and a licensee cannot
236: impose that choice.
237:
238: This section is intended to make thoroughly clear what is believed to
239: be a consequence of the rest of this License.
240:
241: 8. If the distribution and/or use of the Program is restricted in
242: certain countries either by patents or by copyrighted interfaces, the
243: original copyright holder who places the Program under this License
244: may add an explicit geographical distribution limitation excluding
245: those countries, so that distribution is permitted only in or among
246: countries not thus excluded. In such case, this License incorporates
247: the limitation as if written in the body of this License.
248:
249: 9. The Free Software Foundation may publish revised and/or new versions
250: of the General Public License from time to time. Such new versions will
251: be similar in spirit to the present version, but may differ in detail to
252: address new problems or concerns.
253:
254: Each version is given a distinguishing version number. If the Program
255: specifies a version number of this License which applies to it and "any
256: later version", you have the option of following the terms and conditions
257: either of that version or of any later version published by the Free
258: Software Foundation. If the Program does not specify a version number of
259: this License, you may choose any version ever published by the Free Software
260: Foundation.
261:
262: 10. If you wish to incorporate parts of the Program into other free
263: programs whose distribution conditions are different, write to the author
264: to ask for permission. For software which is copyrighted by the Free
265: Software Foundation, write to the Free Software Foundation; we sometimes
266: make exceptions for this. Our decision will be guided by the two goals
267: of preserving the free status of all derivatives of our free software and
268: of promoting the sharing and reuse of software generally.
269:
270: NO WARRANTY
271:
272: 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
273: FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
274: OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
275: PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
276: OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
277: MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
278: TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
279: PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
280: REPAIR OR CORRECTION.
281:
282: 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
283: WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
284: REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
285: INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
286: OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
287: TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
288: YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
289: PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
290: POSSIBILITY OF SUCH DAMAGES.
291:
292: END OF TERMS AND CONDITIONS
293:
294: Appendix: How to Apply These Terms to Your New Programs
295:
296: If you develop a new program, and you want it to be of the greatest
297: possible use to the public, the best way to achieve this is to make it
298: free software which everyone can redistribute and change under these terms.
299:
300: To do so, attach the following notices to the program. It is safest
301: to attach them to the start of each source file to most effectively
302: convey the exclusion of warranty; and each file should have at least
303: the "copyright" line and a pointer to where the full notice is found.
304:
305: <one line to give the program's name and a brief idea of what it does.>
306: Copyright (C) 19yy <name of author>
307:
308: This program is free software; you can redistribute it and/or modify
309: it under the terms of the GNU General Public License as published by
310: the Free Software Foundation; either version 2 of the License, or
311: (at your option) any later version.
312:
313: This program is distributed in the hope that it will be useful,
314: but WITHOUT ANY WARRANTY; without even the implied warranty of
315: MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
316: GNU General Public License for more details.
317:
318: You should have received a copy of the GNU General Public License
319: along with this program; if not, write to the Free Software
320: Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
321:
322: Also add information on how to contact you by electronic and paper mail.
323:
324: If the program is interactive, make it output a short notice like this
325: when it starts in an interactive mode:
326:
327: Gnomovision version 69, Copyright (C) 19yy name of author
328: Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
329: This is free software, and you are welcome to redistribute it
330: under certain conditions; type `show c' for details.
331:
332: The hypothetical commands `show w' and `show c' should show the appropriate
333: parts of the General Public License. Of course, the commands you use may
334: be called something other than `show w' and `show c'; they could even be
335: mouse-clicks or menu items--whatever suits your program.
336:
337: You should also get your employer (if you work as a programmer) or your
338: school, if any, to sign a "copyright disclaimer" for the program, if
339: necessary. Here is a sample; alter the names:
340:
341: Yoyodyne, Inc., hereby disclaims all copyright interest in the program
342: `Gnomovision' (which makes passes at compilers) written by James Hacker.
343:
344: <signature of Ty Coon>, 1 April 1989
345: Ty Coon, President of Vice
346:
347: This General Public License does not permit incorporating your program into
348: proprietary programs. If your program is a subroutine library, you may
349: consider it more useful to permit linking proprietary applications with the
350: library. If this is what you want to do, use the GNU Library General
351: Public License instead of this License.
352:
353: ttyplay.c, io.c and ttyrec.c fall under a 4-clause BSD license,
354: which follows.

386:
387: mygetnstr.c follows the BSD licence as well but only the first two clauses
388: of the one reproduced above.
389:
390: stripgfx.c is derived from drawing.c in the NetHack source distribution,
391: and falls under the NetHack General Public License, which follows.
392:
393: NETHACK GENERAL PUBLIC LICENSE
394: (Copyright 1989 M. Stephenson)
395: .
396: (Based on the BISON general public license,
397: copyright 1988 Richard M. Stallman)
398:
399: Everyone is permitted to copy and distribute verbatim copies of this
400: license, but changing it is not allowed. You can also use this wording to
401: make the terms for other programs.
402:
403: The license agreements of most software companies keep you at the mercy of
404: those companies. By contrast, our general public license is intended to give
405: everyone the right to share NetHack. To make sure that you get the rights we
406: want you to have, we need to make restrictions that forbid anyone to deny you
407: these rights or to ask you to surrender the rights. Hence this license
408: agreement.
409:
410: Specifically, we want to make sure that you have the right to give away
411: copies of NetHack, that you receive source code or else can get it if you
412: want it, that you can change NetHack or use pieces of it in new free
413: programs, and that you know you can do these things.
414:
415: To make sure that everyone has such rights, we have to forbid you to
416: deprive anyone else of these rights. For example, if you distribute copies
417: of NetHack, you must give the recipients all the rights that you have. You
418: must make sure that they, too, receive or can get the source code. And you
419: must tell them their rights.
420:
421: Also, for our own protection, we must make certain that everyone finds out
422: that there is no warranty for NetHack. If NetHack is modified by someone
423: else and passed on, we want its recipients to know that what they have is
424: not what we distributed.
425:
426: Therefore we (Mike Stephenson and other holders of NetHack copyrights) make
427: the following terms which say what you must do to be allowed to distribute or
428: change NetHack.
429:
430:
431: COPYING POLICIES
432:
433: 1. You may copy and distribute verbatim copies of NetHack source code as
434: you receive it, in any medium, provided that you keep intact the notices on
435: all files that refer to copyrights, to this License Agreement, and to the
436: absence of any warranty; and give any other recipients of the NetHack
437: program a copy of this License Agreement along with the program.
438:
439: 2. You may modify your copy or copies of NetHack or any portion of it, and
440: copy and distribute such modifications under the terms of Paragraph 1 above
441: (including distributing this License Agreement), provided that you also do the
442: following:
443:
444: a) cause the modified files to carry prominent notices stating that you
445: changed the files and the date of any change; and
446:
447: b) cause the whole of any work that you distribute or publish, that in
448: whole or in part contains or is a derivative of NetHack or any part
449: thereof, to be licensed at no charge to all third parties on terms
450: identical to those contained in this License Agreement (except that you
451: may choose to grant more extensive warranty protection to some or all
452: third parties, at your option)
453:
454: c) You may charge a distribution fee for the physical act of
455: transferring a copy, and you may at your option offer warranty protection
456: in exchange for a fee.
457:
458: 3. You may copy and distribute NetHack (or a portion or derivative of it,
459: under Paragraph 2) in object code or executable form under the terms of
460: Paragraphs 1 and 2 above provided that you also do one of the following:
461:
462: a) accompany it with the complete machine-readable source code, which
463: must be distributed under the terms of Paragraphs 1 and 2 above; or,
464:
465: b) accompany it with full information as to how to obtain the complete
466: machine-readable source code from an appropriate archive site. (This
467: alternative is allowed only for noncommercial distribution.)
468:
469: For these purposes, complete source code means either the full source
470: distribution as originally released over Usenet or updated copies of the
471: files in this distribution used to create the object code or executable.
472:
473: 4. You may not copy, sublicense, distribute or transfer NetHack except as
474: expressly provided under this License Agreement. Any attempt otherwise to
