1.1 root 1: GNU CHESS GENERAL PUBLIC LICENSE
2:
3: Copyright (C) 1986,1987 Free Software Foundation, Inc.
4: Everyone is permitted to copy and distribute verbatim copies
5: of this license, but changing it is not allowed.
6:
7: The license agreements of most software companies keep you at the
8: mercy of those companies. By contrast, our general public license is
9: intended to give everyone the right to share GNU Chess. To make
10: sure that you get the rights we want you to have, we need to make
11: restrictions that forbid anyone to deny you these rights or to ask you
12: to surrender the rights. Hence this license agreement.
13:
14: Specifically, we want to make sure that you have the right to give
15: away copies of GNU Chess, that you receive source code or else can get it
16: if you want it, that you can change GNU Chess or use pieces of it in new
17: free programs, and that you know you can do these things.
18:
19: To make sure that everyone has such rights, we have to forbid you to
20: deprive anyone else of these rights. For example, if you distribute
21: copies of GNU Chess, you must give the recipients all the rights that you
22: have. You must make sure that they, too, receive or can get the
23: source code. And you must tell them their rights.
24:
25: Also, for our own protection, we must make certain that everyone
26: finds out that there is no warranty for GNU Chess. If GNU Chess is
27: modified by someone else and passed on, we want its recipients to know
28: that what they have is not what we distributed, so that any problems
29: introduced by others will not reflect on our reputation.
30:
31: Therefore the Free Software Foundation, Inc. makes the following
32: terms which say what you must do to be allowed to distribute or change
33: GNU Chess.
34:
35: COPYING POLICIES
36:
37: 1. You may copy and distribute verbatim copies of GNU Chess source
38: code as you receive it, in any medium, provided that you conspicuously
39: and appropriately publish on each file a valid copyright notice
40: "Copyright (C) 1986,1987 Free Software Foundation, Inc.", containing the
41: year of last change for the file in question; keep intact the notices
42: on all files that refer to this License Agreement and to the absence
43: of any warranty; and give any other recipients of the GNU Chess
44: program a copy of this License Agreement along with the program.
45:
46: 2. You may modify your copy or copies of GNU Chess source code or
47: any portion of it, and copy and distribute such modifications under
48: the terms of Paragraph 1 above, provided that you also do the following:
49:
50: a) cause the modified files to carry prominent notices stating
51: who last changed such files and the date of any change; and
52:
53: b) cause the whole of any work that you distribute or publish,
54: that in whole or in part contains or is a derivative of GNU Chess
55: or any part thereof, to be freely distributed
56: and licensed to all third parties on terms identical to those
57: contained in this License Agreement (except that you may choose
58: to grant more extensive warranty protection to third parties,
59: at your option).
60:
61: c) if the modified program serves as a text editor, cause it
62: when started running in the simplest and usual way, to print
63: an announcement including a valid copyright notice ("Copyright
64: (C)", the year of authorship, and all copyright owners' names),
65: saying that there is no warranty (or else, saying that you provide
66: a warranty) and that users may redistribute the program under
67: these conditions, and telling the user how to view a copy of
68: this License Agreement.
69:
70: 3. You may copy and distribute GNU Chess or any portion of it in
71: compiled, executable or object code form under the terms of Paragraphs
72: 1 and 2 above provided that you do the following:
73:
74: a) cause each such copy of GNU Chess to be accompanied by the
75: corresponding machine-readable source code; or
76:
77: b) cause each such copy of GNU Chess to be accompanied by a
78: written offer, with no time limit, to give any third party
79: free (except for a nominal shipping charge) machine readable
80: copy of the corresponding source code; or
81:
82: c) in the case of a recipient of GNU Chess in compiled, executable
83: or object code form (without the corresponding source code) you
84: shall cause copies you distribute to be accompanied by a copy
85: of the written offer of source code which you received along
86: with the copy of GNU Chess.
87:
88: 4. You may not copy, sublicense, distribute or transfer GNU Chess
89: except as expressly provided under this License Agreement. Any attempt
90: otherwise to copy, sublicense, distribute or transfer GNU Chess is void and
91: your rights to use GNU Chess under this License agreement shall be
92: automatically terminated. However, parties who have received computer
93: software programs from you with this License Agreement will not have
94: their licenses terminated so long as such parties remain in full compliance.
95:
96: Your comments and suggestions about our licensing policies and our
97: software are welcome! Please contact the Free Software Foundation, Inc.,
98: 1000 Mass Ave, Cambridge, MA 02138, or call (617) 876-3296.
