2: GNU GENERAL PUBLIC LICENSE
3: Version 1, February 1989
4:
5: Copyright (C) 1989 Free Software Foundation, Inc.
6: 675 Mass Ave, Cambridge, MA 02139, USA
7: Everyone is permitted to copy and distribute verbatim copies
8: of this license document, but changing it is not allowed.
9:
10: Preamble
11:
12: The license agreements of most software companies try to keep users
13: at the mercy of those companies. By contrast, our General Public
14: License is intended to guarantee your freedom to share and change free
15: software--to make sure the software is free for all its users. The
16: General Public License applies to the Free Software Foundation's
17: software and to any other program whose authors commit to using it.
18: You can use it for your programs, too.
19:
20: When we speak of free software, we are referring to freedom, not
21: price. Specifically, the General Public License is designed to make
22: sure that you have the freedom to give away or sell copies of free
23: software, that you receive source code or can get it if you want it,
24: that you can change the software or use pieces of it in new free
25: programs; and that you know you can do these things.
26:
27: To protect your rights, we need to make restrictions that forbid
28: anyone to deny you these rights or to ask you to surrender the rights.
29: These restrictions translate to certain responsibilities for you if you
30: distribute copies of the software, or if you modify it.
31:
32: For example, if you distribute copies of a such a program, whether
33: gratis or for a fee, you must give the recipients all the rights that
34: you have. You must make sure that they, too, receive or can get the
35: source code. And you must tell them their rights.
36:
37: We protect your rights with two steps: (1) copyright the software, and
38: (2) offer you this license which gives you legal permission to copy,
39: distribute and/or modify the software.
40:
41: Also, for each author's protection and ours, we want to make certain
42: that everyone understands that there is no warranty for this free
43: software. If the software is modified by someone else and passed on, we
44: want its recipients to know that what they have is not the original, so
45: that any problems introduced by others will not reflect on the original
46: authors' reputations.
47:
48: The precise terms and conditions for copying, distribution and
49: modification follow.
50:
51: GNU GENERAL PUBLIC LICENSE
52: TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
53:
54: 0. This License Agreement applies to any program or other work which
55: contains a notice placed by the copyright holder saying it may be
56: distributed under the terms of this General Public License. The
57: "Program", below, refers to any such program or work, and a "work based
58: on the Program" means either the Program or any work containing the
59: Program or a portion of it, either verbatim or with modifications. Each
60: licensee is addressed as "you".
61:
62: 1. You may copy and distribute verbatim copies of the Program's source
63: code as you receive it, in any medium, provided that you conspicuously and
64: appropriately publish on each copy an appropriate copyright notice and
65: disclaimer of warranty; keep intact all the notices that refer to this
66: General Public License and to the absence of any warranty; and give any
67: other recipients of the Program a copy of this General Public License
68: along with the Program. You may charge a fee for the physical act of
69: transferring a copy.
70:
71: 2. You may modify your copy or copies of the Program or any portion of
72: it, and copy and distribute such modifications under the terms of Paragraph
73: 1 above, provided that you also do the following:
74:
75: a) cause the modified files to carry prominent notices stating that
76: you changed the files and the date of any change; and
77:
78: b) cause the whole of any work that you distribute or publish, that
79: in whole or in part contains the Program or any part thereof, either
80: with or without modifications, to be licensed at no charge to all
81: third parties under the terms of this General Public License (except
82: that you may choose to grant warranty protection to some or all
83: third parties, at your option).
84:
85: c) If the modified program normally reads commands interactively when
86: run, you must cause it, when started running for such interactive use
87: in the simplest and most usual way, to print or display an
88: announcement including an appropriate copyright notice and a notice
89: that there is no warranty (or else, saying that you provide a
90: warranty) and that users may redistribute the program under these
91: conditions, and telling the user how to view a copy of this General
92: Public License.
93:
94: d) You may charge a fee for the physical act of transferring a
95: copy, and you may at your option offer warranty protection in
96: exchange for a fee.
97:
98: Mere aggregation of another independent work with the Program (or its
99: derivative) on a volume of a storage or distribution medium does not bring
100: the other work under the scope of these terms.
101:
102: 3. You may copy and distribute the Program (or a portion or derivative of
103: it, under Paragraph 2) in object code or executable form under the terms of
104: Paragraphs 1 and 2 above provided that you also do one of the following:
105:
106: a) accompany it with the complete corresponding machine-readable
107: source code, which must be distributed under the terms of
108: Paragraphs 1 and 2 above; or,
109:
110: b) accompany it with a written offer, valid for at least three
111: years, to give any third party free (except for a nominal charge
112: for the cost of distribution) a complete machine-readable copy of the
113: corresponding source code, to be distributed under the terms of
114: Paragraphs 1 and 2 above; or,
115:
116: c) accompany it with the information you received as to where the
117: corresponding source code may be obtained. (This alternative is
118: allowed only for noncommercial distribution and only if you
119: received the program in object code or executable form alone.)
120:
121: Source code for a work means the preferred form of the work for making
122: modifications to it. For an executable file, complete source code means
123: all the source code for all modules it contains; but, as a special
124: exception, it need not include source code for modules which are standard
125: libraries that accompany the operating system on which the executable
126: file runs, or for standard header files or definitions files that
127: accompany that operating system.
128:
129: 4. You may not copy, modify, sublicense, distribute or transfer the
130: Program except as expressly provided under this General Public License.
131: Any attempt otherwise to copy, modify, sublicense, distribute or transfer
132: the Program is void, and will automatically terminate your rights to use
133: the Program under this License. However, parties who have received
134: copies, or rights to use copies, from you under this General Public
135: License will not have their licenses terminated so long as such parties
136: remain in full compliance.
137:
138: 5. By copying, distributing or modifying the Program (or any work based
139: on the Program) you indicate your acceptance of this license to do so,
140: and all its terms and conditions.
141:
142: 6. Each time you redistribute the Program (or any work based on the
143: Program), the recipient automatically receives a license from the original
144: licensor to copy, distribute or modify the Program subject to these
145: terms and conditions. You may not impose any further restrictions on the
146: recipients' exercise of the rights granted herein.
147:
148: 7. The Free Software Foundation may publish revised and/or new versions
149: of the General Public License from time to time. Such new versions will
150: be similar in spirit to the present version, but may differ in detail to
151: address new problems or concerns.
152:
153: Each version is given a distinguishing version number. If the Program
154: specifies a version number of the license which applies to it and "any
155: later version", you have the option of following the terms and conditions
156: either of that version or of any later version published by the Free
157: Software Foundation. If the Program does not specify a version number of
158: the license, you may choose any version ever published by the Free Software
159: Foundation.
160:
161: 8. If you wish to incorporate parts of the Program into other free
162: programs whose distribution conditions are different, write to the author
163: to ask for permission. For software which is copyrighted by the Free
164: Software Foundation, write to the Free Software Foundation; we sometimes
165: make exceptions for this. Our decision will be guided by the two goals
166: of preserving the free status of all derivatives of our free software and
167: of promoting the sharing and reuse of software generally.
168:
169: NO WARRANTY
170:
171: 9. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
172: FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
173: OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
174: PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
175: OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
176: MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
177: TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
178: PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
179: REPAIR OR CORRECTION.
180:
181: 10. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
182: WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
183: REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
184: INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
185: OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
186: TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
187: YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
188: PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
189: POSSIBILITY OF SUCH DAMAGES.
190:
191: END OF TERMS AND CONDITIONS
192:
193: Appendix: How to Apply These Terms to Your New Programs
194:
195: If you develop a new program, and you want it to be of the greatest
196: possible use to humanity, the best way to achieve this is to make it
197: free software which everyone can redistribute and change under these
198: terms.
199:
200: To do so, attach the following notices to the program. It is safest to
201: attach them to the start of each source file to most effectively convey
202: the exclusion of warranty; and each file should have at least the
203: "copyright" line and a pointer to where the full notice is found.
204:
205: <one line to give the program's name and a brief idea of what it does.>
206: Copyright (C) 19yy <name of author>
207:
208: This program is free software; you can redistribute it and/or modify
209: it under the terms of the GNU General Public License as published by
210: the Free Software Foundation; either version 1, or (at your option)
211: any later version.
212:
213: This program is distributed in the hope that it will be useful,
214: but WITHOUT ANY WARRANTY; without even the implied warranty of
215: MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
216: GNU General Public License for more details.
217:
218: You should have received a copy of the GNU General Public License
219: along with this program; if not, write to the Free Software
220: Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
221:
222: Also add information on how to contact you by electronic and paper mail.
223:
224: If the program is interactive, make it output a short notice like this
225: when it starts in an interactive mode:
226:
227: Gnomovision version 69, Copyright (C) 19xx name of author
228: Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
229: This is free software, and you are welcome to redistribute it
230: under certain conditions; type `show c' for details.
231:
232: The hypothetical commands `show w' and `show c' should show the
233: appropriate parts of the General Public License. Of course, the
234: commands you use may be called something other than `show w' and `show
235: c'; they could even be mouse-clicks or menu items--whatever suits your
236: program.
237:
238: You should also get your employer (if you work as a programmer) or your
239: school, if any, to sign a "copyright disclaimer" for the program, if
240: necessary. Here a sample; alter the names:
241:
242: Yoyodyne, Inc., hereby disclaims all copyright interest in the
243: program `Gnomovision' (a program to direct compilers to make passes
244: at assemblers) written by James Hacker.
245:

249: That's all there is to it!
