1 GNU GENERAL PUBLIC LICENSE | |
2 | |
3 Version 2, June 1991 | |
4 | |
5 Copyright (C) 1989, 1991 Free Software Foundation, Inc. 675 Mass Ave, | |
6 Cambridge, MA 02139, USA. Everyone is permitted to copy and distribute | |
7 verbatim copies of this license document, but changing it is not allowed. | |
8 | |
9 Preamble | |
10 | |
11 The licenses for most software are designed to take away your freedom to | |
12 share and change it. By contrast, the GNU General Public License is | |
13 intended to guarantee your freedom to share and change free software--to | |
14 make sure the software is free for all its users. This General Public License | |
15 applies to most of the Free Software Foundation's software and to any other | |
16 program whose authors commit to using it. (Some other Free Software | |
17 Foundation software is covered by the GNU Library General Public License | |
18 instead.) You can apply it to your programs, too. | |
19 | |
20 When we speak of free software, we are referring to freedom, not price. Our | |
21 General Public Licenses are designed to make sure that you have the | |
22 freedom to distribute copies of free software (and charge for this service if | |
23 you wish), that you receive source code or can get it if you want it, that you | |
24 can change the software or use pieces of it in new free programs; and that | |
25 you know you can do these things. | |
26 | |
27 To protect your rights, we need to make restrictions that forbid anyone to | |
28 deny you these rights or to ask you to surrender the rights. These restrictions | |
29 translate to certain responsibilities for you if you distribute copies of the | |
30 software, or if you modify it. | |
31 | |
32 For example, if you distribute copies of such a program, whether gratis or for | |
33 a fee, you must give the recipients all the rights that you have. You must make | |
34 sure that they, too, receive or can get the source code. And you must show | |
35 them these terms so they know their rights. | |
36 | |
37 We protect your rights with two steps: (1) copyright the software, and (2) | |
38 offer you this license which gives you legal permission to copy, distribute | |
39 and/or modify the software. | |
40 | |
41 Also, for each author's protection and ours, we want to make certain that | |
42 everyone understands that there is no warranty for this free software. If the | |
43 software is modified by someone else and passed on, we want its recipients | |
44 to know that what they have is not the original, so that any problems | |
45 introduced by others will not reflect on the original authors' reputations. | |
46 | |
47 Finally, any free program is threatened constantly by software patents. We | |
48 wish to avoid the danger that redistributors of a free program will individually | |
49 obtain patent licenses, in effect making the program proprietary. To prevent | |
50 this, we have made it clear that any patent must be licensed for everyone's | |
51 free use or not licensed at all. | |
52 | |
53 The precise terms and conditions for copying, distribution and modification | |
54 follow. | |
55 | |
56 GNU GENERAL PUBLIC LICENSE | |
57 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND | |
58 MODIFICATION | |
59 | |
60 0. This License applies to any program or other work which contains a notice | |
61 placed by the copyright holder saying it may be distributed under the terms | |
62 of this General Public License. The "Program", below, refers to any such | |
63 program or work, and a "work based on the Program" means either the | |
64 Program or any derivative work under copyright law: that is to say, a work | |
65 containing the Program or a portion of it, either verbatim or with | |
66 modifications and/or translated into another language. (Hereinafter, translation | |
67 is included without limitation in the term "modification".) Each licensee is | |
68 addressed as "you". | |
69 | |
70 Activities other than copying, distribution and modification are not covered | |
71 by this License; they are outside its scope. The act of running the Program is | |
72 not restricted, and the output from the Program is covered only if its contents | |
73 constitute a work based on the Program (independent of having been made | |
74 by running the Program). Whether that is true depends on what the Program | |
75 does. | |
76 | |
77 1. You may copy and distribute verbatim copies of the Program's source | |
78 code as you receive it, in any medium, provided that you conspicuously and | |
79 appropriately publish on each copy an appropriate copyright notice and | |
80 disclaimer of warranty; keep intact all the notices that refer to this License | |
81 and to the absence of any warranty; and give any other recipients of the | |
82 Program a copy of this License along with the Program. | |
83 | |
84 You may charge a fee for the physical act of transferring a copy, and you | |
85 may at your option offer warranty protection in exchange for a fee. | |
86 | |
87 2. You may modify your copy or copies of the Program or any portion of it, | |
88 thus forming a work based on the Program, and copy and distribute such | |
89 modifications or work under the terms of Section 1 above, provided that you | |
90 also meet all of these conditions: | |
91 | |
92 a) You must cause the modified files to carry prominent notices stating that | |
93 you changed the files and the date of any change. | |
94 | |
95 b) You must cause any work that you distribute or publish, that in whole or in | |
96 part contains or is derived from the Program or any part thereof, to be | |
97 licensed as a whole at no charge to all third parties under the terms of this | |
98 License. | |
99 | |
100 c) If the modified program normally reads commands interactively when run, | |
101 you must cause it, when started running for such interactive use in the most | |
102 ordinary way, to print or display an announcement including an appropriate | |
103 copyright notice and a notice that there is no warranty (or else, saying that | |
104 you provide a warranty) and that users may redistribute the program under | |
105 these conditions, and telling the user how to view a copy of this License. | |
106 (Exception: if the Program itself is interactive but does not normally print such | |
107 an announcement, your work based on the Program is not required to print | |
108 an announcement.) | |
109 | |
110 These requirements apply to the modified work as a whole. If identifiable | |
111 sections of that work are not derived from the Program, and can be | |
112 reasonably considered independent and separate works in themselves, then | |
113 this License, and its terms, do not apply to those sections when you distribute | |
114 them as separate works. But when you distribute the same sections as part | |
115 of a whole which is a work based on the Program, the distribution of the | |
116 whole must be on the terms of this License, whose permissions for other | |
117 licensees extend to the entire whole, and thus to each and every part | |
118 regardless of who wrote it. | |
119 | |
120 Thus, it is not the intent of this section to claim rights or contest your rights to | |
121 work written entirely by you; rather, the intent is to exercise the right to | |
122 control the distribution of derivative or collective works based on the | |
123 Program. | |
124 | |
125 In addition, mere aggregation of another work not based on the Program | |
126 with the Program (or with a work based on the Program) on a volume of a | |
127 storage or distribution medium does not bring the other work under the scope | |
128 of this License. | |
129 | |
130 3. You may copy and distribute the Program (or a work based on it, under | |
131 Section 2) in object code or executable form under the terms of Sections 1 | |
132 and 2 above provided that you also do one of the following: | |
133 | |
134 a) Accompany it with the complete corresponding machine-readable source | |
135 code, which must be distributed under the terms of Sections 1 and 2 above | |
136 on a medium customarily used for software interchange; or, | |
137 | |
138 b) Accompany it with a written offer, valid for at least three years, to give | |
139 any third party, for a charge no more than your cost of physically performing | |
140 source distribution, a complete machine-readable copy of the corresponding | |
141 source code, to be distributed under the terms of Sections 1 and 2 above on | |
142 a medium customarily used for software interchange; or, | |
143 | |
144 c) Accompany it with the information you received as to the offer to distribute | |
145 corresponding source code. (This alternative is allowed only for | |
146 noncommercial distribution and only if you received the program in object | |
147 code or executable form with such an offer, in accord with Subsection b | |
148 above.) | |
149 | |
150 The source code for a work means the preferred form of the work for | |
151 making modifications to it. For an executable work, complete source code | |
152 means all the source code for all modules it contains, plus any associated | |
153 interface definition files, plus the scripts used to control compilation and | |
154 installation of the executable. However, as a special exception, the source | |
155 code distributed need not include anything that is normally distributed (in | |
156 either source or binary form) with the major components (compiler, kernel, | |
157 and so on) of the operating system on which the executable runs, unless that | |
158 component itself accompanies the executable. | |
159 | |
160 If distribution of executable or object code is made by offering access to | |
161 copy from a designated place, then offering equivalent access to copy the | |
162 source code from the same place counts as distribution of the source code, | |
163 even though third parties are not compelled to copy the source along with the | |
164 object code. | |
165 | |
166 4. You may not copy, modify, sublicense, or distribute the Program except as | |
167 expressly provided under this License. Any attempt otherwise to copy, | |
168 modify, sublicense or distribute the Program is void, and will automatically | |
169 terminate your rights under this License. However, parties who have received | |
170 copies, or rights, from you under this License will not have their licenses | |
171 terminated so long as such parties remain in full compliance. | |
172 | |
173 5. You are not required to accept this License, since you have not signed it. | |
174 However, nothing else grants you permission to modify or distribute the | |
175 Program or its derivative works. These actions are prohibited by law if you | |
176 do not accept this License. Therefore, by modifying or distributing the | |
177 Program (or any work based on the Program), you indicate your acceptance | |
178 of this License to do so, and all its terms and conditions for copying, | |
179 distributing or modifying the Program or works based on it. | |
180 | |
181 6. Each time you redistribute the Program (or any work based on the | |
182 Program), the recipient automatically receives a license from the original | |
183 licensor to copy, distribute or modify the Program subject to these terms and | |
184 conditions. You may not impose any further restrictions on the recipients' | |
185 exercise of the rights granted herein. You are not responsible for enforcing | |
186 compliance by third parties to this License. | |
187 | |
188 7. If, as a consequence of a court judgment or allegation of patent | |
189 infringement or for any other reason (not limited to patent issues), conditions | |
190 are imposed on you (whether by court order, agreement or otherwise) that | |
191 contradict the conditions of this License, they do not excuse you from the | |
192 conditions of this License. If you cannot distribute so as to satisfy | |
193 simultaneously your obligations under this License and any other pertinent | |
194 obligations, then as a consequence you may not distribute the Program at all. | |
195 For example, if a patent license would not permit royalty-free redistribution | |
196 of the Program by all those who receive copies directly or indirectly through | |
197 you, then the only way you could satisfy both it and this License would be to | |
198 refrain entirely from distribution of the Program. | |
199 | |
200 If any portion of this section is held invalid or unenforceable under any | |
201 particular circumstance, the balance of the section is intended to apply and | |
202 the section as a whole is intended to apply in other circumstances. | |
203 | |
204 It is not the purpose of this section to induce you to infringe any patents or | |
205 other property right claims or to contest validity of any such claims; this | |
206 section has the sole purpose of protecting the integrity of the free software | |
207 distribution system, which is implemented by public license practices. Many | |
208 people have made generous contributions to the wide range of software | |
209 distributed through that system in reliance on consistent application of that | |
210 system; it is up to the author/donor to decide if he or she is willing to | |
211 distribute software through any other system and a licensee cannot impose | |
212 that choice. | |
213 | |
214 This section is intended to make thoroughly clear what is believed to be a | |
215 consequence of the rest of this License. | |
216 | |
217 8. If the distribution and/or use of the Program is restricted in certain | |
218 countries either by patents or by copyrighted interfaces, the original copyright | |
219 holder who places the Program under this License may add an explicit | |
220 geographical distribution limitation excluding those countries, so that | |
221 distribution is permitted only in or among countries not thus excluded. In such | |
222 case, this License incorporates the limitation as if written in the body of this | |
223 License. | |
224 | |
225 9. The Free Software Foundation may publish revised and/or new versions | |
226 of the General Public License from time to time. Such new versions will be | |
227 similar in spirit to the present version, but may differ in detail to address new | |
228 problems or concerns. | |
229 | |
230 Each version is given a distinguishing version number. If the Program specifies | |
231 a version number of this License which applies to it and "any later version", | |
232 you have the option of following the terms and conditions either of that | |
233 version or of any later version published by the Free Software Foundation. If | |
234 the Program does not specify a version number of this License, you may | |
235 choose any version ever published by the Free Software Foundation. | |
236 | |
237 10. If you wish to incorporate parts of the Program into other free programs | |
238 whose distribution conditions are different, write to the author to ask for | |
239 permission. For software which is copyrighted by the Free Software | |
240 Foundation, write to the Free Software Foundation; we sometimes make | |
241 exceptions for this. Our decision will be guided by the two goals of | |
242 preserving the free status of all derivatives of our free software and of | |
243 promoting the sharing and reuse of software generally. | |
244 | |
245 NO WARRANTY | |
246 | |
247 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, | |
248 THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT | |
249 PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE | |
250 STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR | |
251 OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT | |
252 WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, | |
253 INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES | |
254 OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR | |
255 PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND | |
256 PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE | |
257 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL | |
258 NECESSARY SERVICING, REPAIR OR CORRECTION. | |
259 | |
260 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR | |
261 AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR | |
262 ANY OTHER PARTY WHO MAY MODIFY AND/OR | |
263 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE | |
264 LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, | |
265 SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES | |
266 ARISING OUT OF THE USE OR INABILITY TO USE THE | |
267 PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA | |
268 OR DATA BEING RENDERED INACCURATE OR LOSSES | |
269 SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE | |
270 PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN | |
271 IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF | |
272 THE POSSIBILITY OF SUCH DAMAGES. | |
273 | |
274 END OF TERMS AND CONDITIONS |
