16 | Version 3, 29 June 2007 |
---|
17 | |
---|
18 | Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/> |
---|
19 | Everyone is permitted to copy and distribute verbatim copies |
---|
20 | of this license document, but changing it is not allowed. |
---|
21 | |
---|
22 | |
---|
23 | This version of the GNU Lesser General Public License incorporates |
---|
24 | the terms and conditions of version 3 of the GNU General Public |
---|
25 | License, supplemented by the additional permissions listed below. |
---|
26 | |
---|
27 | 0. Additional Definitions. |
---|
28 | |
---|
29 | As used herein, "this License" refers to version 3 of the GNU Lesser |
---|
30 | General Public License, and the "GNU GPL" refers to version 3 of the GNU |
---|
31 | General Public License. |
---|
32 | |
---|
33 | "The Library" refers to a covered work governed by this License, |
---|
34 | other than an Application or a Combined Work as defined below. |
---|
35 | |
---|
36 | An "Application" is any work that makes use of an interface provided |
---|
37 | by the Library, but which is not otherwise based on the Library. |
---|
38 | Defining a subclass of a class defined by the Library is deemed a mode |
---|
39 | of using an interface provided by the Library. |
---|
40 | |
---|
41 | A "Combined Work" is a work produced by combining or linking an |
---|
42 | Application with the Library. The particular version of the Library |
---|
43 | with which the Combined Work was made is also called the "Linked |
---|
44 | Version". |
---|
45 | |
---|
46 | The "Minimal Corresponding Source" for a Combined Work means the |
---|
47 | Corresponding Source for the Combined Work, excluding any source code |
---|
48 | for portions of the Combined Work that, considered in isolation, are |
---|
49 | based on the Application, and not on the Linked Version. |
---|
50 | |
---|
51 | The "Corresponding Application Code" for a Combined Work means the |
---|
52 | object code and/or source code for the Application, including any data |
---|
53 | and utility programs needed for reproducing the Combined Work from the |
---|
54 | Application, but excluding the System Libraries of the Combined Work. |
---|
55 | |
---|
56 | 1. Exception to Section 3 of the GNU GPL. |
---|
57 | |
---|
58 | You may convey a covered work under sections 3 and 4 of this License |
---|
59 | without being bound by section 3 of the GNU GPL. |
---|
60 | |
---|
61 | 2. Conveying Modified Versions. |
---|
62 | |
---|
63 | If you modify a copy of the Library, and, in your modifications, a |
---|
64 | facility refers to a function or data to be supplied by an Application |
---|
65 | that uses the facility (other than as an argument passed when the |
---|
66 | facility is invoked), then you may convey a copy of the modified |
---|
67 | version: |
---|
68 | |
---|
69 | a) under this License, provided that you make a good faith effort to |
---|
70 | ensure that, in the event an Application does not supply the |
---|
71 | function or data, the facility still operates, and performs |
---|
72 | whatever part of its purpose remains meaningful, or |
---|
73 | |
---|
74 | b) under the GNU GPL, with none of the additional permissions of |
---|
75 | this License applicable to that copy. |
---|
76 | |
---|
77 | 3. Object Code Incorporating Material from Library Header Files. |
---|
78 | |
---|
79 | The object code form of an Application may incorporate material from |
---|
80 | a header file that is part of the Library. You may convey such object |
---|
81 | code under terms of your choice, provided that, if the incorporated |
---|
82 | material is not limited to numerical parameters, data structure |
---|
83 | layouts and accessors, or small macros, inline functions and templates |
---|
84 | (ten or fewer lines in length), you do both of the following: |
---|
85 | |
---|
86 | a) Give prominent notice with each copy of the object code that the |
---|
87 | Library is used in it and that the Library and its use are |
---|
88 | covered by this License. |
---|
89 | |
---|
90 | b) Accompany the object code with a copy of the GNU GPL and this license |
---|
91 | document. |
---|
92 | |
---|
93 | 4. Combined Works. |
---|
94 | |
---|
95 | You may convey a Combined Work under terms of your choice that, |
---|
96 | taken together, effectively do not restrict modification of the |
---|
97 | portions of the Library contained in the Combined Work and reverse |
---|
98 | engineering for debugging such modifications, if you also do each of |
---|
99 | the following: |
---|
100 | |
---|
101 | a) Give prominent notice with each copy of the Combined Work that |
---|
102 | the Library is used in it and that the Library and its use are |
---|
103 | covered by this License. |
---|
104 | |
---|
105 | b) Accompany the Combined Work with a copy of the GNU GPL and this license |
---|
106 | document. |
---|
107 | |
---|
108 | c) For a Combined Work that displays copyright notices during |
---|
109 | execution, include the copyright notice for the Library among |
---|
110 | these notices, as well as a reference directing the user to the |
---|
111 | copies of the GNU GPL and this license document. |
---|
112 | |
---|
113 | d) Do one of the following: |
---|
114 | |
---|
115 | 0) Convey the Minimal Corresponding Source under the terms of this |
---|
116 | License, and the Corresponding Application Code in a form |
---|
117 | suitable for, and under terms that permit, the user to |
---|
118 | recombine or relink the Application with a modified version of |
---|
119 | the Linked Version to produce a modified Combined Work, in the |
---|
120 | manner specified by section 6 of the GNU GPL for conveying |
---|
121 | Corresponding Source. |
---|
122 | |
---|
123 | 1) Use a suitable shared library mechanism for linking with the |
---|
124 | Library. A suitable mechanism is one that (a) uses at run time |
---|
125 | a copy of the Library already present on the user's computer |
---|
126 | system, and (b) will operate properly with a modified version |
---|
127 | of the Library that is interface-compatible with the Linked |
---|
128 | Version. |
---|
129 | |
---|
130 | e) Provide Installation Information, but only if you would otherwise |
---|
131 | be required to provide such information under section 6 of the |
---|
132 | GNU GPL, and only to the extent that such information is |
---|
133 | necessary to install and execute a modified version of the |
---|
134 | Combined Work produced by recombining or relinking the |
---|
135 | Application with a modified version of the Linked Version. (If |
---|
136 | you use option 4d0, the Installation Information must accompany |
---|
137 | the Minimal Corresponding Source and Corresponding Application |
---|
138 | Code. If you use option 4d1, you must provide the Installation |
---|
139 | Information in the manner specified by section 6 of the GNU GPL |
---|
140 | for conveying Corresponding Source.) |
---|
141 | |
---|
142 | 5. Combined Libraries. |
---|
143 | |
---|
144 | You may place library facilities that are a work based on the |
---|
145 | Library side by side in a single library together with other library |
---|
146 | facilities that are not Applications and are not covered by this |
---|
147 | License, and convey such a combined library under terms of your |
---|
148 | choice, if you do both of the following: |
---|
149 | |
---|
150 | a) Accompany the combined library with a copy of the same work based |
---|
151 | on the Library, uncombined with any other library facilities, |
---|
152 | conveyed under the terms of this License. |
---|
153 | |
---|
154 | b) Give prominent notice with the combined library that part of it |
---|
155 | is a work based on the Library, and explaining where to find the |
---|
156 | accompanying uncombined form of the same work. |
---|
157 | |
---|
158 | 6. Revised Versions of the GNU Lesser General Public License. |
---|
159 | |
---|
160 | The Free Software Foundation may publish revised and/or new versions |
---|
161 | of the GNU Lesser General Public License from time to time. Such new |
---|
162 | versions will be similar in spirit to the present version, but may |
---|
163 | differ in detail to address new problems or concerns. |
---|
164 | |
---|
165 | Each version is given a distinguishing version number. If the |
---|
166 | Library as you received it specifies that a certain numbered version |
---|
167 | of the GNU Lesser General Public License "or any later version" |
---|
168 | applies to it, you have the option of following the terms and |
---|
169 | conditions either of that published version or of any later version |
---|
170 | published by the Free Software Foundation. If the Library as you |
---|
171 | received it does not specify a version number of the GNU Lesser |
---|
172 | General Public License, you may choose any version of the GNU Lesser |
---|
173 | General Public License ever published by the Free Software Foundation. |
---|
174 | |
---|
175 | If the Library as you received it specifies that a proxy can decide |
---|
176 | whether future versions of the GNU Lesser General Public License shall |
---|
177 | apply, that proxy's public statement of acceptance of any version is |
---|
178 | permanent authorization for you to choose that version for the |
---|
179 | Library. |
---|

184 | GNU GENERAL PUBLIC LICENSE |
---|
185 | Version 3, 29 June 2007 |
---|
186 | |
---|
187 | Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/> |
---|
188 | Everyone is permitted to copy and distribute verbatim copies |
---|
189 | of this license document, but changing it is not allowed. |
---|
190 | |
---|
191 | Preamble |
---|
192 | |
---|
193 | The GNU General Public License is a free, copyleft license for |
---|
194 | software and other kinds of works. |
---|
195 | |
---|
196 | The licenses for most software and other practical works are designed |
---|
197 | to take away your freedom to share and change the works. By contrast, |
---|
198 | the GNU General Public License is intended to guarantee your freedom to |
---|
199 | share and change all versions of a program--to make sure it remains free |
---|
200 | software for all its users. We, the Free Software Foundation, use the |
---|
201 | GNU General Public License for most of our software; it applies also to |
---|
202 | any other work released this way by its authors. You can apply it to |
---|
203 | your programs, too. |
---|
204 | |
---|
205 | When we speak of free software, we are referring to freedom, not |
---|
206 | price. Our General Public Licenses are designed to make sure that you |
---|
207 | have the freedom to distribute copies of free software (and charge for |
---|
208 | them if you wish), that you receive source code or can get it if you |
---|
209 | want it, that you can change the software or use pieces of it in new |
---|
210 | free programs, and that you know you can do these things. |
---|
211 | |
---|
212 | To protect your rights, we need to prevent others from denying you |
---|
213 | these rights or asking you to surrender the rights. Therefore, you have |
---|
214 | certain responsibilities if you distribute copies of the software, or if |
---|
215 | you modify it: responsibilities to respect the freedom of others. |
---|
216 | |
---|
217 | For example, if you distribute copies of such a program, whether |
---|
218 | gratis or for a fee, you must pass on to the recipients the same |
---|
219 | freedoms that you received. You must make sure that they, too, receive |
---|
220 | or can get the source code. And you must show them these terms so they |
---|
221 | know their rights. |
---|
222 | |
---|
223 | Developers that use the GNU GPL protect your rights with two steps: |
---|
224 | (1) assert copyright on the software, and (2) offer you this License |
---|
225 | giving you legal permission to copy, distribute and/or modify it. |
---|
226 | |
---|
227 | For the developers' and authors' protection, the GPL clearly explains |
---|
228 | that there is no warranty for this free software. For both users' and |
---|
229 | authors' sake, the GPL requires that modified versions be marked as |
---|
230 | changed, so that their problems will not be attributed erroneously to |
---|
231 | authors of previous versions. |
---|
232 | |
---|
233 | Some devices are designed to deny users access to install or run |
---|
234 | modified versions of the software inside them, although the manufacturer |
---|
235 | can do so. This is fundamentally incompatible with the aim of |
---|
236 | protecting users' freedom to change the software. The systematic |
---|
237 | pattern of such abuse occurs in the area of products for individuals to |
---|
238 | use, which is precisely where it is most unacceptable. Therefore, we |
---|
239 | have designed this version of the GPL to prohibit the practice for those |
---|
240 | products. If such problems arise substantially in other domains, we |
---|
241 | stand ready to extend this provision to those domains in future versions |
---|
242 | of the GPL, as needed to protect the freedom of users. |
---|
243 | |
---|
244 | Finally, every program is threatened constantly by software patents. |
---|
245 | States should not allow patents to restrict development and use of |
---|
246 | software on general-purpose computers, but in those that do, we wish to |
---|
247 | avoid the special danger that patents applied to a free program could |
---|
248 | make it effectively proprietary. To prevent this, the GPL assures that |
---|
249 | patents cannot be used to render the program non-free. |
---|
250 | |
---|
251 | The precise terms and conditions for copying, distribution and |
---|
252 | modification follow. |
---|
253 | |
---|
254 | TERMS AND CONDITIONS |
---|
255 | |
---|
256 | 0. Definitions. |
---|
257 | |
---|
258 | "This License" refers to version 3 of the GNU General Public License. |
---|
259 | |
---|
260 | "Copyright" also means copyright-like laws that apply to other kinds of |
---|
261 | works, such as semiconductor masks. |
---|
262 | |
---|
263 | "The Program" refers to any copyrightable work licensed under this |
---|
264 | License. Each licensee is addressed as "you". "Licensees" and |
---|
265 | "recipients" may be individuals or organizations. |
---|
266 | |
---|
267 | To "modify" a work means to copy from or adapt all or part of the work |
---|
268 | in a fashion requiring copyright permission, other than the making of an |
---|
269 | exact copy. The resulting work is called a "modified version" of the |
---|
270 | earlier work or a work "based on" the earlier work. |
---|
271 | |
---|
272 | A "covered work" means either the unmodified Program or a work based |
---|
273 | on the Program. |
---|
274 | |
---|
275 | To "propagate" a work means to do anything with it that, without |
---|
276 | permission, would make you directly or secondarily liable for |
---|
277 | infringement under applicable copyright law, except executing it on a |
---|
278 | computer or modifying a private copy. Propagation includes copying, |
---|
279 | distribution (with or without modification), making available to the |
---|
280 | public, and in some countries other activities as well. |
---|
281 | |
---|
282 | To "convey" a work means any kind of propagation that enables other |
---|
283 | parties to make or receive copies. Mere interaction with a user through |
---|
284 | a computer network, with no transfer of a copy, is not conveying. |
---|
285 | |
---|
286 | An interactive user interface displays "Appropriate Legal Notices" |
---|
287 | to the extent that it includes a convenient and prominently visible |
---|
288 | feature that (1) displays an appropriate copyright notice, and (2) |
---|
289 | tells the user that there is no warranty for the work (except to the |
---|
290 | extent that warranties are provided), that licensees may convey the |
---|
291 | work under this License, and how to view a copy of this License. If |
---|
292 | the interface presents a list of user commands or options, such as a |
---|
293 | menu, a prominent item in the list meets this criterion. |
---|
294 | |
---|
295 | 1. Source Code. |
---|
296 | |
---|
297 | The "source code" for a work means the preferred form of the work |
---|
298 | for making modifications to it. "Object code" means any non-source |
---|
299 | form of a work. |
---|
300 | |
---|
301 | A "Standard Interface" means an interface that either is an official |
---|
302 | standard defined by a recognized standards body, or, in the case of |
---|
303 | interfaces specified for a particular programming language, one that |
---|
304 | is widely used among developers working in that language. |
---|
305 | |
---|
306 | The "System Libraries" of an executable work include anything, other |
---|
307 | than the work as a whole, that (a) is included in the normal form of |
---|
308 | packaging a Major Component, but which is not part of that Major |
---|
309 | Component, and (b) serves only to enable use of the work with that |
---|
310 | Major Component, or to implement a Standard Interface for which an |
---|
311 | implementation is available to the public in source code form. A |
---|
312 | "Major Component", in this context, means a major essential component |
---|
313 | (kernel, window system, and so on) of the specific operating system |
---|
314 | (if any) on which the executable work runs, or a compiler used to |
---|
315 | produce the work, or an object code interpreter used to run it. |
---|
316 | |
---|
317 | The "Corresponding Source" for a work in object code form means all |
---|
318 | the source code needed to generate, install, and (for an executable |
---|
319 | work) run the object code and to modify the work, including scripts to |
---|
320 | control those activities. However, it does not include the work's |
---|
321 | System Libraries, or general-purpose tools or generally available free |
---|
322 | programs which are used unmodified in performing those activities but |
---|
323 | which are not part of the work. For example, Corresponding Source |
---|
324 | includes interface definition files associated with source files for |
---|
325 | the work, and the source code for shared libraries and dynamically |
---|
326 | linked subprograms that the work is specifically designed to require, |
---|
327 | such as by intimate data communication or control flow between those |
---|
328 | subprograms and other parts of the work. |
---|
329 | |
---|
330 | The Corresponding Source need not include anything that users |
---|
331 | can regenerate automatically from other parts of the Corresponding |
---|
332 | Source. |
---|
333 | |
---|
334 | The Corresponding Source for a work in source code form is that |
---|
335 | same work. |
---|
336 | |
---|
337 | 2. Basic Permissions. |
---|
338 | |
---|
339 | All rights granted under this License are granted for the term of |
---|
340 | copyright on the Program, and are irrevocable provided the stated |
---|
341 | conditions are met. This License explicitly affirms your unlimited |
---|
342 | permission to run the unmodified Program. The output from running a |
---|
343 | covered work is covered by this License only if the output, given its |
---|
344 | content, constitutes a covered work. This License acknowledges your |
---|
345 | rights of fair use or other equivalent, as provided by copyright law. |
---|
346 | |
---|
347 | You may make, run and propagate covered works that you do not |
---|
348 | convey, without conditions so long as your license otherwise remains |
---|
349 | in force. You may convey covered works to others for the sole purpose |
---|
350 | of having them make modifications exclusively for you, or provide you |
---|
351 | with facilities for running those works, provided that you comply with |
---|
352 | the terms of this License in conveying all material for which you do |
---|
353 | not control copyright. Those thus making or running the covered works |
---|
354 | for you must do so exclusively on your behalf, under your direction |
---|
355 | and control, on terms that prohibit them from making any copies of |
---|
356 | your copyrighted material outside their relationship with you. |
---|
357 | |
---|
358 | Conveying under any other circumstances is permitted solely under |
---|
359 | the conditions stated below. Sublicensing is not allowed; section 10 |
---|
360 | makes it unnecessary. |
---|
361 | |
---|
362 | 3. Protecting Users' Legal Rights From Anti-Circumvention Law. |
---|
363 | |
---|
364 | No covered work shall be deemed part of an effective technological |
---|
365 | measure under any applicable law fulfilling obligations under article |
---|
366 | 11 of the WIPO copyright treaty adopted on 20 December 1996, or |
---|
367 | similar laws prohibiting or restricting circumvention of such |
---|
368 | measures. |
---|
369 | |
---|
370 | When you convey a covered work, you waive any legal power to forbid |
---|
371 | circumvention of technological measures to the extent such circumvention |
---|
372 | is effected by exercising rights under this License with respect to |
---|
373 | the covered work, and you disclaim any intention to limit operation or |
---|
374 | modification of the work as a means of enforcing, against the work's |
---|
375 | users, your or third parties' legal rights to forbid circumvention of |
---|
376 | technological measures. |
---|
377 | |
---|
378 | 4. Conveying Verbatim Copies. |
---|
379 | |
---|
380 | You may convey verbatim copies of the Program's source code as you |
---|
381 | receive it, in any medium, provided that you conspicuously and |
---|
382 | appropriately publish on each copy an appropriate copyright notice; |
---|
383 | keep intact all notices stating that this License and any |
---|
384 | non-permissive terms added in accord with section 7 apply to the code; |
---|
385 | keep intact all notices of the absence of any warranty; and give all |
---|
386 | recipients a copy of this License along with the Program. |
---|
387 | |
---|
388 | You may charge any price or no price for each copy that you convey, |
---|
389 | and you may offer support or warranty protection for a fee. |
---|
390 | |
---|
391 | 5. Conveying Modified Source Versions. |
---|
392 | |
---|
393 | You may convey a work based on the Program, or the modifications to |
---|
394 | produce it from the Program, in the form of source code under the |
---|
395 | terms of section 4, provided that you also meet all of these conditions: |
---|
396 | |
---|
397 | a) The work must carry prominent notices stating that you modified |
---|
398 | it, and giving a relevant date. |
---|
399 | |
---|
400 | b) The work must carry prominent notices stating that it is |
---|
401 | released under this License and any conditions added under section |
---|
402 | 7. This requirement modifies the requirement in section 4 to |
---|
403 | "keep intact all notices". |
---|
404 | |
---|
405 | c) You must license the entire work, as a whole, under this |
---|
406 | License to anyone who comes into possession of a copy. This |
---|
407 | License will therefore apply, along with any applicable section 7 |
---|
408 | additional terms, to the whole of the work, and all its parts, |
---|
409 | regardless of how they are packaged. This License gives no |
---|
410 | permission to license the work in any other way, but it does not |
---|
411 | invalidate such permission if you have separately received it. |
---|
412 | |
---|
413 | d) If the work has interactive user interfaces, each must display |
---|
414 | Appropriate Legal Notices; however, if the Program has interactive |
---|
415 | interfaces that do not display Appropriate Legal Notices, your |
---|
416 | work need not make them do so. |
---|
417 | |
---|
418 | A compilation of a covered work with other separate and independent |
---|
419 | works, which are not by their nature extensions of the covered work, |
---|
420 | and which are not combined with it such as to form a larger program, |
---|
421 | in or on a volume of a storage or distribution medium, is called an |
---|
422 | "aggregate" if the compilation and its resulting copyright are not |
---|
423 | used to limit the access or legal rights of the compilation's users |
---|
424 | beyond what the individual works permit. Inclusion of a covered work |
---|
425 | in an aggregate does not cause this License to apply to the other |
---|
426 | parts of the aggregate. |
---|
427 | |
---|
428 | 6. Conveying Non-Source Forms. |
---|
429 | |
---|
430 | You may convey a covered work in object code form under the terms |
---|
431 | of sections 4 and 5, provided that you also convey the |
---|
432 | machine-readable Corresponding Source under the terms of this License, |
---|
433 | in one of these ways: |
---|
434 | |
---|
435 | a) Convey the object code in, or embodied in, a physical product |
---|
436 | (including a physical distribution medium), accompanied by the |
---|
437 | Corresponding Source fixed on a durable physical medium |
---|
438 | customarily used for software interchange. |
---|
439 | |
---|
440 | b) Convey the object code in, or embodied in, a physical product |
---|
441 | (including a physical distribution medium), accompanied by a |
---|
442 | written offer, valid for at least three years and valid for as |
---|
443 | long as you offer spare parts or customer support for that product |
---|
444 | model, to give anyone who possesses the object code either (1) a |
---|
445 | copy of the Corresponding Source for all the software in the |
---|
446 | product that is covered by this License, on a durable physical |
---|
447 | medium customarily used for software interchange, for a price no |
---|
448 | more than your reasonable cost of physically performing this |
---|
449 | conveying of source, or (2) access to copy the |
---|
450 | Corresponding Source from a network server at no charge. |
---|
451 | |
---|
452 | c) Convey individual copies of the object code with a copy of the |
---|
453 | written offer to provide the Corresponding Source. This |
---|
454 | alternative is allowed only occasionally and noncommercially, and |
---|
455 | only if you received the object code with such an offer, in accord |
---|
456 | with subsection 6b. |
---|
457 | |
---|
458 | d) Convey the object code by offering access from a designated |
---|
459 | place (gratis or for a charge), and offer equivalent access to the |
---|
460 | Corresponding Source in the same way through the same place at no |
---|
461 | further charge. You need not require recipients to copy the |
---|
462 | Corresponding Source along with the object code. If the place to |
---|
463 | copy the object code is a network server, the Corresponding Source |
---|
464 | may be on a different server (operated by you or a third party) |
---|
465 | that supports equivalent copying facilities, provided you maintain |
---|
466 | clear directions next to the object code saying where to find the |
---|
467 | Corresponding Source. Regardless of what server hosts the |
---|
468 | Corresponding Source, you remain obligated to ensure that it is |
---|
469 | available for as long as needed to satisfy these requirements. |
---|
470 | |
---|
471 | e) Convey the object code using peer-to-peer transmission, provided |
---|
472 | you inform other peers where the object code and Corresponding |
---|
473 | Source of the work are being offered to the general public at no |
---|
474 | charge under subsection 6d. |
---|
475 | |
---|
476 | A separable portion of the object code, whose source code is excluded |
---|
477 | from the Corresponding Source as a System Library, need not be |
---|
478 | included in conveying the object code work. |
---|
479 | |
---|
480 | A "User Product" is either (1) a "consumer product", which means any |
---|
481 | tangible personal property which is normally used for personal, family, |
---|
482 | or household purposes, or (2) anything designed or sold for incorporation |
---|
483 | into a dwelling. In determining whether a product is a consumer product, |
---|
484 | doubtful cases shall be resolved in favor of coverage. For a particular |
---|
485 | product received by a particular user, "normally used" refers to a |
---|
486 | typical or common use of that class of product, regardless of the status |
---|
487 | of the particular user or of the way in which the particular user |
---|
488 | actually uses, or expects or is expected to use, the product. A product |
---|
489 | is a consumer product regardless of whether the product has substantial |
---|
490 | commercial, industrial or non-consumer uses, unless such uses represent |
---|
491 | the only significant mode of use of the product. |
---|
492 | |
---|
493 | "Installation Information" for a User Product means any methods, |
---|
494 | procedures, authorization keys, or other information required to install |
---|
495 | and execute modified versions of a covered work in that User Product from |
---|
496 | a modified version of its Corresponding Source. The information must |
---|
497 | suffice to ensure that the continued functioning of the modified object |
---|
498 | code is in no case prevented or interfered with solely because |
---|
499 | modification has been made. |
---|
500 | |
---|
501 | If you convey an object code work under this section in, or with, or |
---|
502 | specifically for use in, a User Product, and the conveying occurs as |
---|
503 | part of a transaction in which the right of possession and use of the |
---|
504 | User Product is transferred to the recipient in perpetuity or for a |
---|
505 | fixed term (regardless of how the transaction is characterized), the |
---|
506 | Corresponding Source conveyed under this section must be accompanied |
---|
507 | by the Installation Information. But this requirement does not apply |
---|
508 | if neither you nor any third party retains the ability to install |
---|
509 | modified object code on the User Product (for example, the work has |
---|
510 | been installed in ROM). |
---|
511 | |
---|
512 | The requirement to provide Installation Information does not include a |
---|
513 | requirement to continue to provide support service, warranty, or updates |
---|
514 | for a work that has been modified or installed by the recipient, or for |
---|
515 | the User Product in which it has been modified or installed. Access to a |
---|
516 | network may be denied when the modification itself materially and |
---|
517 | adversely affects the operation of the network or violates the rules and |
---|
518 | protocols for communication across the network. |
---|
519 | |
---|
520 | Corresponding Source conveyed, and Installation Information provided, |
---|
521 | in accord with this section must be in a format that is publicly |
---|
522 | documented (and with an implementation available to the public in |
---|
523 | source code form), and must require no special password or key for |
---|
524 | unpacking, reading or copying. |
---|
525 | |
---|
526 | 7. Additional Terms. |
---|
527 | |
---|
528 | "Additional permissions" are terms that supplement the terms of this |
---|
529 | License by making exceptions from one or more of its conditions. |
---|
530 | Additional permissions that are applicable to the entire Program shall |
---|
531 | be treated as though they were included in this License, to the extent |
---|
532 | that they are valid under applicable law. If additional permissions |
---|
533 | apply only to part of the Program, that part may be used separately |
---|
534 | under those permissions, but the entire Program remains governed by |
---|
535 | this License without regard to the additional permissions. |
---|
536 | |
---|
537 | When you convey a copy of a covered work, you may at your option |
---|
538 | remove any additional permissions from that copy, or from any part of |
---|
539 | it. (Additional permissions may be written to require their own |
---|
540 | removal in certain cases when you modify the work.) You may place |
---|
541 | additional permissions on material, added by you to a covered work, |
---|
542 | for which you have or can give appropriate copyright permission. |
---|
543 | |
---|
544 | Notwithstanding any other provision of this License, for material you |
---|
545 | add to a covered work, you may (if authorized by the copyright holders of |
---|
546 | that material) supplement the terms of this License with terms: |
---|
547 | |
---|
548 | a) Disclaiming warranty or limiting liability differently from the |
---|
549 | terms of sections 15 and 16 of this License; or |
---|
550 | |
---|
551 | b) Requiring preservation of specified reasonable legal notices or |
---|
552 | author attributions in that material or in the Appropriate Legal |
---|
553 | Notices displayed by works containing it; or |
---|
554 | |
---|
555 | c) Prohibiting misrepresentation of the origin of that material, or |
---|
556 | requiring that modified versions of such material be marked in |
---|
557 | reasonable ways as different from the original version; or |
---|
558 | |
---|
559 | d) Limiting the use for publicity purposes of names of licensors or |
---|
560 | authors of the material; or |
---|
561 | |
---|
562 | e) Declining to grant rights under trademark law for use of some |
---|
563 | trade names, trademarks, or service marks; or |
---|
564 | |
---|
565 | f) Requiring indemnification of licensors and authors of that |
---|
566 | material by anyone who conveys the material (or modified versions of |
---|
567 | it) with contractual assumptions of liability to the recipient, for |
---|
568 | any liability that these contractual assumptions directly impose on |
---|
569 | those licensors and authors. |
---|
570 | |
---|
571 | All other non-permissive additional terms are considered "further |
---|
572 | restrictions" within the meaning of section 10. If the Program as you |
---|
573 | received it, or any part of it, contains a notice stating that it is |
---|
574 | governed by this License along with a term that is a further |
---|
575 | restriction, you may remove that term. If a license document contains |
---|
576 | a further restriction but permits relicensing or conveying under this |
---|
577 | License, you may add to a covered work material governed by the terms |
---|
578 | of that license document, provided that the further restriction does |
---|
579 | not survive such relicensing or conveying. |
---|
580 | |
---|
581 | If you add terms to a covered work in accord with this section, you |
---|
582 | must place, in the relevant source files, a statement of the |
---|
583 | additional terms that apply to those files, or a notice indicating |
---|
584 | where to find the applicable terms. |
---|
585 | |
---|
586 | Additional terms, permissive or non-permissive, may be stated in the |
---|
587 | form of a separately written license, or stated as exceptions; |
---|
588 | the above requirements apply either way. |
---|
589 | |
---|
590 | 8. Termination. |
---|
591 | |
---|
592 | You may not propagate or modify a covered work except as expressly |
---|
593 | provided under this License. Any attempt otherwise to propagate or |
---|
594 | modify it is void, and will automatically terminate your rights under |
---|
595 | this License (including any patent licenses granted under the third |
---|
596 | paragraph of section 11). |
---|
597 | |
---|
598 | However, if you cease all violation of this License, then your |
---|
599 | license from a particular copyright holder is reinstated (a) |
---|
600 | provisionally, unless and until the copyright holder explicitly and |
---|
601 | finally terminates your license, and (b) permanently, if the copyright |
---|
602 | holder fails to notify you of the violation by some reasonable means |
---|
603 | prior to 60 days after the cessation. |
---|
604 | |
---|
605 | Moreover, your license from a particular copyright holder is |
---|
606 | reinstated permanently if the copyright holder notifies you of the |
---|
607 | violation by some reasonable means, this is the first time you have |
---|
608 | received notice of violation of this License (for any work) from that |
---|
609 | copyright holder, and you cure the violation prior to 30 days after |
---|
610 | your receipt of the notice. |
---|
611 | |
---|
612 | Termination of your rights under this section does not terminate the |
---|
613 | licenses of parties who have received copies or rights from you under |
---|
614 | this License. If your rights have been terminated and not permanently |
---|
615 | reinstated, you do not qualify to receive new licenses for the same |
---|
616 | material under section 10. |
---|
617 | |
---|
618 | 9. Acceptance Not Required for Having Copies. |
---|
619 | |
---|
620 | You are not required to accept this License in order to receive or |
---|
621 | run a copy of the Program. Ancillary propagation of a covered work |
---|
622 | occurring solely as a consequence of using peer-to-peer transmission |
---|
623 | to receive a copy likewise does not require acceptance. However, |
---|
624 | nothing other than this License grants you permission to propagate or |
---|
625 | modify any covered work. These actions infringe copyright if you do |
---|
626 | not accept this License. Therefore, by modifying or propagating a |
---|
627 | covered work, you indicate your acceptance of this License to do so. |
---|
628 | |
---|
629 | 10. Automatic Licensing of Downstream Recipients. |
---|
630 | |
---|
631 | Each time you convey a covered work, the recipient automatically |
---|
632 | receives a license from the original licensors, to run, modify and |
---|
633 | propagate that work, subject to this License. You are not responsible |
---|
634 | for enforcing compliance by third parties with this License. |
---|
635 | |
---|
636 | An "entity transaction" is a transaction transferring control of an |
---|
637 | organization, or substantially all assets of one, or subdividing an |
---|
638 | organization, or merging organizations. If propagation of a covered |
---|
639 | work results from an entity transaction, each party to that |
---|
640 | transaction who receives a copy of the work also receives whatever |
---|
641 | licenses to the work the party's predecessor in interest had or could |
---|
642 | give under the previous paragraph, plus a right to possession of the |
---|
643 | Corresponding Source of the work from the predecessor in interest, if |
---|
644 | the predecessor has it or can get it with reasonable efforts. |
---|
645 | |
---|
646 | You may not impose any further restrictions on the exercise of the |
---|
647 | rights granted or affirmed under this License. For example, you may |
---|
648 | not impose a license fee, royalty, or other charge for exercise of |
---|
649 | rights granted under this License, and you may not initiate litigation |
---|
650 | (including a cross-claim or counterclaim in a lawsuit) alleging that |
---|
651 | any patent claim is infringed by making, using, selling, offering for |
---|
652 | sale, or importing the Program or any portion of it. |
---|
653 | |
---|
654 | 11. Patents. |
---|
655 | |
---|
656 | A "contributor" is a copyright holder who authorizes use under this |
---|
657 | License of the Program or a work on which the Program is based. The |
---|
658 | work thus licensed is called the contributor's "contributor version". |
---|
659 | |
---|
660 | A contributor's "essential patent claims" are all patent claims |
---|
661 | owned or controlled by the contributor, whether already acquired or |
---|
662 | hereafter acquired, that would be infringed by some manner, permitted |
---|
663 | by this License, of making, using, or selling its contributor version, |
---|
664 | but do not include claims that would be infringed only as a |
---|
665 | consequence of further modification of the contributor version. For |
---|
666 | purposes of this definition, "control" includes the right to grant |
---|
667 | patent sublicenses in a manner consistent with the requirements of |
---|
668 | this License. |
---|
669 | |
---|
670 | Each contributor grants you a non-exclusive, worldwide, royalty-free |
---|
671 | patent license under the contributor's essential patent claims, to |
---|
672 | make, use, sell, offer for sale, import and otherwise run, modify and |
---|
673 | propagate the contents of its contributor version. |
---|
674 | |
---|
675 | In the following three paragraphs, a "patent license" is any express |
---|
676 | agreement or commitment, however denominated, not to enforce a patent |
---|
677 | (such as an express permission to practice a patent or covenant not to |
---|
678 | sue for patent infringement). To "grant" such a patent license to a |
---|
679 | party means to make such an agreement or commitment not to enforce a |
---|
680 | patent against the party. |
---|
681 | |
---|
682 | If you convey a covered work, knowingly relying on a patent license, |
---|
683 | and the Corresponding Source of the work is not available for anyone |
---|
684 | to copy, free of charge and under the terms of this License, through a |
---|
685 | publicly available network server or other readily accessible means, |
---|
686 | then you must either (1) cause the Corresponding Source to be so |
---|
687 | available, or (2) arrange to deprive yourself of the benefit of the |
---|
688 | patent license for this particular work, or (3) arrange, in a manner |
---|
689 | consistent with the requirements of this License, to extend the patent |
---|
690 | license to downstream recipients. "Knowingly relying" means you have |
---|
691 | actual knowledge that, but for the patent license, your conveying the |
---|
692 | covered work in a country, or your recipient's use of the covered work |
---|
693 | in a country, would infringe one or more identifiable patents in that |
---|
694 | country that you have reason to believe are valid. |
---|
695 | |
---|
696 | If, pursuant to or in connection with a single transaction or |
---|
697 | arrangement, you convey, or propagate by procuring conveyance of, a |
---|
698 | covered work, and grant a patent license to some of the parties |
---|
699 | receiving the covered work authorizing them to use, propagate, modify |
---|
700 | or convey a specific copy of the covered work, then the patent license |
---|
701 | you grant is automatically extended to all recipients of the covered |
---|
702 | work and works based on it. |
---|
703 | |
---|
704 | A patent license is "discriminatory" if it does not include within |
---|
705 | the scope of its coverage, prohibits the exercise of, or is |
---|
706 | conditioned on the non-exercise of one or more of the rights that are |
---|
707 | specifically granted under this License. You may not convey a covered |
---|
708 | work if you are a party to an arrangement with a third party that is |
---|
709 | in the business of distributing software, under which you make payment |
---|
710 | to the third party based on the extent of your activity of conveying |
---|
711 | the work, and under which the third party grants, to any of the |
---|
712 | parties who would receive the covered work from you, a discriminatory |
---|
713 | patent license (a) in connection with copies of the covered work |
---|
714 | conveyed by you (or copies made from those copies), or (b) primarily |
---|
715 | for and in connection with specific products or compilations that |
---|
716 | contain the covered work, unless you entered into that arrangement, |
---|
717 | or that patent license was granted, prior to 28 March 2007. |
---|
718 | |
---|
719 | Nothing in this License shall be construed as excluding or limiting |
---|
720 | any implied license or other defenses to infringement that may |
---|
721 | otherwise be available to you under applicable patent law. |
---|
722 | |
---|
723 | 12. No Surrender of Others' Freedom. |
---|
724 | |
---|
725 | If conditions are imposed on you (whether by court order, agreement or |
---|
726 | otherwise) that contradict the conditions of this License, they do not |
---|
727 | excuse you from the conditions of this License. If you cannot convey a |
---|
728 | covered work so as to satisfy simultaneously your obligations under this |
---|
729 | License and any other pertinent obligations, then as a consequence you may |
---|
730 | not convey it at all. For example, if you agree to terms that obligate you |
---|
731 | to collect a royalty for further conveying from those to whom you convey |
---|
732 | the Program, the only way you could satisfy both those terms and this |
---|
733 | License would be to refrain entirely from conveying the Program. |
---|
734 | |
---|
735 | 13. Use with the GNU Affero General Public License. |
---|
736 | |
---|
737 | Notwithstanding any other provision of this License, you have |
---|
738 | permission to link or combine any covered work with a work licensed |
---|
739 | under version 3 of the GNU Affero General Public License into a single |
---|
740 | combined work, and to convey the resulting work. The terms of this |
---|
741 | License will continue to apply to the part which is the covered work, |
---|
742 | but the special requirements of the GNU Affero General Public License, |
---|
743 | section 13, concerning interaction through a network will apply to the |
---|
744 | combination as such. |
---|
745 | |
---|
746 | 14. Revised Versions of this License. |
---|
747 | |
---|
748 | The Free Software Foundation may publish revised and/or new versions of |
---|
749 | the GNU General Public License from time to time. Such new versions will |
---|
750 | be similar in spirit to the present version, but may differ in detail to |
---|
751 | address new problems or concerns. |
---|
752 | |
---|
753 | Each version is given a distinguishing version number. If the |
---|
754 | Program specifies that a certain numbered version of the GNU General |
---|
755 | Public License "or any later version" applies to it, you have the |
---|
756 | option of following the terms and conditions either of that numbered |
---|
757 | version or of any later version published by the Free Software |
---|
758 | Foundation. If the Program does not specify a version number of the |
---|
759 | GNU General Public License, you may choose any version ever published |
---|
760 | by the Free Software Foundation. |
---|
761 | |
---|
762 | If the Program specifies that a proxy can decide which future |
---|
763 | versions of the GNU General Public License can be used, that proxy's |
---|
764 | public statement of acceptance of a version permanently authorizes you |
---|
765 | to choose that version for the Program. |
---|
766 | |
---|
767 | Later license versions may give you additional or different |
---|
768 | permissions. However, no additional obligations are imposed on any |
---|
769 | author or copyright holder as a result of your choosing to follow a |

771 | |

772 | 15. Disclaimer of Warranty. |
---|
773 | |
---|
774 | THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY |
---|
775 | APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT |
---|
776 | HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY |
---|
777 | OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, |
---|
778 | THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR |
---|
779 | PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM |
---|
780 | IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF |

---|
786 | WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS |
---|
787 | THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY |
---|
788 | GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE |
---|
789 | USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF |
---|
790 | DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD |
---|
791 | PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), |

---|
796 | |
---|
797 | If the disclaimer of warranty and limitation of liability provided |
---|
798 | above cannot be given local legal effect according to their terms, |
---|
799 | reviewing courts shall apply local law that most closely approximates |
---|
800 | an absolute waiver of all civil liability in connection with the |
---|
801 | Program, unless a warranty or assumption of liability accompanies a |
---|
802 | copy of the Program in return for a fee. |

805 | |
---|
806 | How to Apply These Terms to Your New Programs |
---|
807 | |
---|
808 | If you develop a new program, and you want it to be of the greatest |
---|
809 | possible use to the public, the best way to achieve this is to make it |
---|
810 | free software which everyone can redistribute and change under these terms. |
---|
811 | |
---|
812 | To do so, attach the following notices to the program. It is safest |
---|
813 | to attach them to the start of each source file to most effectively |
---|
814 | state the exclusion of warranty; and each file should have at least |
---|
815 | the "copyright" line and a pointer to where the full notice is found. |
---|
816 | |
---|
817 | <one line to give the program's name and a brief idea of what it does.> |
---|
818 | Copyright (C) <year> <name of author> |
---|
819 | |
---|
820 | This program is free software: you can redistribute it and/or modify |
---|
821 | it under the terms of the GNU General Public License as published by |
---|
822 | the Free Software Foundation, either version 3 of the License, or |
---|
823 | (at your option) any later version. |
---|
824 | |
---|
825 | This program is distributed in the hope that it will be useful, |
---|
826 | but WITHOUT ANY WARRANTY; without even the implied warranty of |
---|
827 | MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the |
---|
828 | GNU General Public License for more details. |
---|
829 | |

830 | You should have received a copy of the GNU General Public License |
---|
831 | along with this program. If not, see <http://www.gnu.org/licenses/>. |
---|
832 | |
---|
833 | Also add information on how to contact you by electronic and paper mail. |
---|
834 | |
---|
835 | If the program does terminal interaction, make it output a short |
---|
836 | notice like this when it starts in an interactive mode: |
---|
837 | |
---|
838 | <program> Copyright (C) <year> <name of author> |
---|
839 | This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. |
---|
840 | This is free software, and you are welcome to redistribute it |
---|
841 | under certain conditions; type `show c' for details. |
---|
842 | |
---|
843 | The hypothetical commands `show w' and `show c' should show the appropriate |
---|
844 | parts of the General Public License. Of course, your program's commands |
---|
845 | might be different; for a GUI interface, you would use an "about box". |
---|
846 | |
---|
847 | You should also get your employer (if you work as a programmer) or school, |
---|
848 | if any, to sign a "copyright disclaimer" for the program, if necessary. |
---|

851 | |
---|
852 | The GNU General Public License does not permit incorporating your program |
---|
853 | into proprietary programs. If your program is a subroutine library, you |
---|
854 | may consider it more useful to permit linking proprietary applications with |
---|
855 | the library. If this is what you want to do, use the GNU Lesser General |
---|
856 | Public License instead of this License. But first, please read |
