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

275 | The Artistic License |
---|
276 | |
---|
277 | Preamble |
---|
278 | |
---|
279 | The intent of this document is to state the conditions under which a Package |
---|
280 | may be copied, such that the Copyright Holder maintains some semblance of |
---|
281 | artistic control over the development of the package, while giving the users of the |
---|
282 | package the right to use and distribute the Package in a more-or-less customary |
---|
283 | fashion, plus the right to make reasonable modifications. |
---|
284 | |
---|
285 | Definitions: |
---|
286 | |
---|
287 | - "Package" refers to the collection of files distributed by the Copyright |
---|
288 | Holder, and derivatives of that collection of files created through textual |
---|
289 | modification. |
---|
290 | - "Standard Version" refers to such a Package if it has not been modified, |
---|
291 | or has been modified in accordance with the wishes of the Copyright |
---|
292 | Holder. |
---|
293 | - "Copyright Holder" is whoever is named in the copyright or copyrights for |
---|
294 | the package. |
---|
295 | - "You" is you, if you're thinking about copying or distributing this Package. |
---|
296 | - "Reasonable copying fee" is whatever you can justify on the basis of |
---|
297 | media cost, duplication charges, time of people involved, and so on. (You |
---|
298 | will not be required to justify it to the Copyright Holder, but only to the |
---|
299 | computing community at large as a market that must bear the fee.) |
---|
300 | - "Freely Available" means that no fee is charged for the item itself, though |
---|
301 | there may be fees involved in handling the item. It also means that |
---|
302 | recipients of the item may redistribute it under the same conditions they |
---|
303 | received it. |
---|
304 | |
---|
305 | 1. You may make and give away verbatim copies of the source form of the |
---|
306 | Standard Version of this Package without restriction, provided that you duplicate |
---|
307 | all of the original copyright notices and associated disclaimers. |
---|
308 | |
---|
309 | 2. You may apply bug fixes, portability fixes and other modifications derived from |
---|
310 | the Public Domain or from the Copyright Holder. A Package modified in such a |
---|
311 | way shall still be considered the Standard Version. |
---|
312 | |
---|
313 | 3. You may otherwise modify your copy of this Package in any way, provided |
---|
314 | that you insert a prominent notice in each changed file stating how and when |
---|
315 | you changed that file, and provided that you do at least ONE of the following: |
---|
316 | |
---|
317 | a) place your modifications in the Public Domain or otherwise |
---|
318 | make them Freely Available, such as by posting said modifications |
---|
319 | to Usenet or an equivalent medium, or placing the modifications on |
---|
320 | a major archive site such as ftp.uu.net, or by allowing the |
---|
321 | Copyright Holder to include your modifications in the Standard |
---|
322 | Version of the Package. |
---|
323 | |
---|
324 | b) use the modified Package only within your corporation or |
---|
325 | organization. |
---|
326 | |
---|
327 | c) rename any non-standard executables so the names do not |
---|
328 | conflict with standard executables, which must also be provided, |
---|
329 | and provide a separate manual page for each non-standard |
---|
330 | executable that clearly documents how it differs from the Standard |
---|
331 | Version. |
---|
332 | |
---|
333 | d) make other distribution arrangements with the Copyright Holder. |
---|
334 | |
---|
335 | 4. You may distribute the programs of this Package in object code or executable |
---|
336 | form, provided that you do at least ONE of the following: |
---|
337 | |
---|
338 | a) distribute a Standard Version of the executables and library |
---|
339 | files, together with instructions (in the manual page or equivalent) |
---|
340 | on where to get the Standard Version. |
---|
341 | |
---|
342 | b) accompany the distribution with the machine-readable source of |
---|
343 | the Package with your modifications. |
---|
344 | |
---|
345 | c) accompany any non-standard executables with their |
---|
346 | corresponding Standard Version executables, giving the |
---|
347 | non-standard executables non-standard names, and clearly |
---|
348 | documenting the differences in manual pages (or equivalent), |
---|
349 | together with instructions on where to get the Standard Version. |
---|
350 | |
---|
351 | d) make other distribution arrangements with the Copyright Holder. |
---|
352 | |
---|
353 | 5. You may charge a reasonable copying fee for any distribution of this Package. |
---|
354 | You may charge any fee you choose for support of this Package. You may not |
---|
355 | charge a fee for this Package itself. However, you may distribute this Package in |
---|
356 | aggregate with other (possibly commercial) programs as part of a larger |
---|
357 | (possibly commercial) software distribution provided that you do not advertise |
---|
358 | this Package as a product of your own. |
---|
359 | |
---|
360 | 6. The scripts and library files supplied as input to or produced as output from |
---|
361 | the programs of this Package do not automatically fall under the copyright of this |
---|
362 | Package, but belong to whomever generated them, and may be sold |
---|
363 | commercially, and may be aggregated with this Package. |
---|
364 | |
---|
365 | 7. C or perl subroutines supplied by you and linked into this Package shall not |
---|
366 | be considered part of this Package. |
---|
367 | |
---|
368 | 8. The name of the Copyright Holder may not be used to endorse or promote |
---|
369 | products derived from this software without specific prior written permission. |
---|
