// Version 3, 29 June 2007
|

//
|

// Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
|
10 |
// Everyone is permitted to copy and distribute verbatim copies
|
11 |
// of this license document, but changing it is not allowed.
|
12 |
//
|
13 |
// Preamble
|
14 |
//
|
15 |
// The GNU General Public License is a free, copyleft license for
|
16 |
//software and other kinds of works.
|
17 |
//
|
18 |
// The licenses for most software and other practical works are designed
|
19 |
//to take away your freedom to share and change the works. By contrast,
|
20 |
//the GNU General Public License is intended to guarantee your freedom to
|
21 |
//share and change all versions of a program--to make sure it remains free
|
22 |
//software for all its users. We, the Free Software Foundation, use the
|
23 |
//GNU General Public License for most of our software; it applies also to
|
24 |
//any other work released this way by its authors. You can apply it to
|
25 |
//your programs, too.
|
26 |
//
|
27 |
// When we speak of free software, we are referring to freedom, not
|
28 |
//price. Our General Public Licenses are designed to make sure that you
|
29 |
//have the freedom to distribute copies of free software (and charge for
|
30 |
//them if you wish), that you receive source code or can get it if you
|
31 |
//want it, that you can change the software or use pieces of it in new
|
32 |
//free programs, and that you know you can do these things.
|
33 |
//
|
34 |
// To protect your rights, we need to prevent others from denying you
|
35 |
//these rights or asking you to surrender the rights. Therefore, you have
|
36 |
//certain responsibilities if you distribute copies of the software, or if
|
37 |
//you modify it: responsibilities to respect the freedom of others.
|
38 |
//
|
39 |
// For example, if you distribute copies of such a program, whether
|
40 |
//gratis or for a fee, you must pass on to the recipients the same
|
41 |
//freedoms that you received. You must make sure that they, too, receive
|
42 |
//or can get the source code. And you must show them these terms so they
|
43 |
//know their rights.
|
44 |
//
|
45 |
// Developers that use the GNU GPL protect your rights with two steps:
|
46 |
//(1) assert copyright on the software, and (2) offer you this License
|
47 |
//giving you legal permission to copy, distribute and/or modify it.
|
48 |
//
|
49 |
// For the developers' and authors' protection, the GPL clearly explains
|
50 |
//that there is no warranty for this free software. For both users' and
|
51 |
//authors' sake, the GPL requires that modified versions be marked as
|
52 |
//changed, so that their problems will not be attributed erroneously to
|
53 |
//authors of previous versions.
|
54 |
//
|
55 |
// Some devices are designed to deny users access to install or run
|
56 |
//modified versions of the software inside them, although the manufacturer
|
57 |
//can do so. This is fundamentally incompatible with the aim of
|
58 |
//protecting users' freedom to change the software. The systematic
|
59 |
//pattern of such abuse occurs in the area of products for individuals to
|
60 |
//use, which is precisely where it is most unacceptable. Therefore, we
|
61 |
//have designed this version of the GPL to prohibit the practice for those
|
62 |
//products. If such problems arise substantially in other domains, we
|
63 |
//stand ready to extend this provision to those domains in future versions
|
64 |
//of the GPL, as needed to protect the freedom of users.
|
65 |
//
|
66 |
// Finally, every program is threatened constantly by software patents.
|
67 |
//States should not allow patents to restrict development and use of
|
68 |
//software on general-purpose computers, but in those that do, we wish to
|
69 |
//avoid the special danger that patents applied to a free program could
|
70 |
//make it effectively proprietary. To prevent this, the GPL assures that
|
71 |
//patents cannot be used to render the program non-free.
|
72 |
//
|
73 |
// The precise terms and conditions for copying, distribution and
|
74 |
//modification follow.
|
75 |
//
|
76 |
// TERMS AND CONDITIONS
|
77 |
//
|
78 |
// 0. Definitions.
|
79 |
//
|
80 |
// "This License" refers to version 3 of the GNU General Public License.
|
81 |
//
|
82 |
// "Copyright" also means copyright-like laws that apply to other kinds of
|
83 |
//works, such as semiconductor masks.
|
84 |
//
|
85 |
// "The Program" refers to any copyrightable work licensed under this
|
86 |
//License. Each licensee is addressed as "you". "Licensees" and
|
87 |
//"recipients" may be individuals or organizations.
|
88 |
//
|
89 |
// To "modify" a work means to copy from or adapt all or part of the work
|
90 |
//in a fashion requiring copyright permission, other than the making of an
|
91 |
//exact copy. The resulting work is called a "modified version" of the
|
92 |
//earlier work or a work "based on" the earlier work.
|
93 |
//
|
94 |
// A "covered work" means either the unmodified Program or a work based
|
95 |
//on the Program.
|
96 |
//
|
97 |
// To "propagate" a work means to do anything with it that, without
|
98 |
//permission, would make you directly or secondarily liable for
|
99 |
//infringement under applicable copyright law, except executing it on a
|
100 |
//computer or modifying a private copy. Propagation includes copying,
|
101 |
//distribution (with or without modification), making available to the
|
102 |
//public, and in some countries other activities as well.
|
103 |
//
|
104 |
// To "convey" a work means any kind of propagation that enables other
|
105 |
//parties to make or receive copies. Mere interaction with a user through
|
106 |
//a computer network, with no transfer of a copy, is not conveying.
|
107 |
//
|
108 |
// An interactive user interface displays "Appropriate Legal Notices"
|
109 |
//to the extent that it includes a convenient and prominently visible
|
110 |
//feature that (1) displays an appropriate copyright notice, and (2)
|
111 |
//tells the user that there is no warranty for the work (except to the
|
112 |
//extent that warranties are provided), that licensees may convey the
|
113 |
//work under this License, and how to view a copy of this License. If
|
114 |
//the interface presents a list of user commands or options, such as a
|
115 |
//menu, a prominent item in the list meets this criterion.
|
116 |
//
|
117 |
// 1. Source Code.
|
118 |
//
|
119 |
// The "source code" for a work means the preferred form of the work
|
120 |
//for making modifications to it. "Object code" means any non-source
|
121 |
//form of a work.
|
122 |
//
|
123 |
// A "Standard Interface" means an interface that either is an official
|
124 |
//standard defined by a recognized standards body, or, in the case of
|
125 |
//interfaces specified for a particular programming language, one that
|
126 |
//is widely used among developers working in that language.
|
127 |
//
|
128 |
// The "System Libraries" of an executable work include anything, other
|
129 |
//than the work as a whole, that (a) is included in the normal form of
|
130 |
//packaging a Major Component, but which is not part of that Major
|
131 |
//Component, and (b) serves only to enable use of the work with that
|
132 |
//Major Component, or to implement a Standard Interface for which an
|
133 |
//implementation is available to the public in source code form. A
|
134 |
//"Major Component", in this context, means a major essential component
|
135 |
//(kernel, window system, and so on) of the specific operating system
|
136 |
//(if any) on which the executable work runs, or a compiler used to
|
137 |
//produce the work, or an object code interpreter used to run it.
|
138 |
//
|
139 |
// The "Corresponding Source" for a work in object code form means all
|
140 |
//the source code needed to generate, install, and (for an executable
|
141 |
//work) run the object code and to modify the work, including scripts to
|
142 |
//control those activities. However, it does not include the work's
|
143 |
//System Libraries, or general-purpose tools or generally available free
|
144 |
//programs which are used unmodified in performing those activities but
|
145 |
//which are not part of the work. For example, Corresponding Source
|
146 |
//includes interface definition files associated with source files for
|
147 |
//the work, and the source code for shared libraries and dynamically
|
148 |
//linked subprograms that the work is specifically designed to require,
|
149 |
//such as by intimate data communication or control flow between those
|
150 |
//subprograms and other parts of the work.
|
151 |
//
|
152 |
// The Corresponding Source need not include anything that users
|
153 |
//can regenerate automatically from other parts of the Corresponding
|
154 |
//Source.
|
155 |
//
|
156 |
// The Corresponding Source for a work in source code form is that
|
157 |
//same work.
|
158 |
//
|
159 |
// 2. Basic Permissions.
|
160 |
//
|
161 |
// All rights granted under this License are granted for the term of
|
162 |
//copyright on the Program, and are irrevocable provided the stated
|
163 |
//conditions are met. This License explicitly affirms your unlimited
|
164 |
//permission to run the unmodified Program. The output from running a
|
165 |
//covered work is covered by this License only if the output, given its
|
166 |
//content, constitutes a covered work. This License acknowledges your
|
167 |
//rights of fair use or other equivalent, as provided by copyright law.
|
168 |
//
|
169 |
// You may make, run and propagate covered works that you do not
|
170 |
//convey, without conditions so long as your license otherwise remains
|
171 |
//in force. You may convey covered works to others for the sole purpose
|
172 |
//of having them make modifications exclusively for you, or provide you
|
173 |
//with facilities for running those works, provided that you comply with
|
174 |
//the terms of this License in conveying all material for which you do
|
175 |
//not control copyright. Those thus making or running the covered works
|
176 |
//for you must do so exclusively on your behalf, under your direction
|
177 |
//and control, on terms that prohibit them from making any copies of
|
178 |
//your copyrighted material outside their relationship with you.
|
179 |
//
|
180 |
// Conveying under any other circumstances is permitted solely under
|
181 |
//the conditions stated below. Sublicensing is not allowed; section 10
|
182 |
//makes it unnecessary.
|
183 |
//
|
184 |
// 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
|
185 |
//
|
186 |
// No covered work shall be deemed part of an effective technological
|
187 |
//measure under any applicable law fulfilling obligations under article
|
188 |
//11 of the WIPO copyright treaty adopted on 20 December 1996, or
|
189 |
//similar laws prohibiting or restricting circumvention of such
|
190 |
//measures.
|
191 |
//
|
192 |
// When you convey a covered work, you waive any legal power to forbid
|
193 |
//circumvention of technological measures to the extent such circumvention
|
194 |
//is effected by exercising rights under this License with respect to
|
195 |
//the covered work, and you disclaim any intention to limit operation or
|
196 |
//modification of the work as a means of enforcing, against the work's
|
197 |
//users, your or third parties' legal rights to forbid circumvention of
|
198 |
//technological measures.
|
199 |
//
|
200 |
// 4. Conveying Verbatim Copies.
|
201 |
//
|
202 |
// You may convey verbatim copies of the Program's source code as you
|
203 |
//receive it, in any medium, provided that you conspicuously and
|
204 |
//appropriately publish on each copy an appropriate copyright notice;
|
205 |
//keep intact all notices stating that this License and any
|
206 |
//non-permissive terms added in accord with section 7 apply to the code;
|
207 |
//keep intact all notices of the absence of any warranty; and give all
|
208 |
//recipients a copy of this License along with the Program.
|
209 |
//
|
210 |
// You may charge any price or no price for each copy that you convey,
|
211 |
//and you may offer support or warranty protection for a fee.
|
212 |
//
|
213 |
// 5. Conveying Modified Source Versions.
|
214 |
//
|
215 |
// You may convey a work based on the Program, or the modifications to
|
216 |
//produce it from the Program, in the form of source code under the
|
217 |
//terms of section 4, provided that you also meet all of these conditions:
|
218 |
//
|
219 |
// a) The work must carry prominent notices stating that you modified
|
220 |
// it, and giving a relevant date.
|
221 |
//
|
222 |
// b) The work must carry prominent notices stating that it is
|
223 |
// released under this License and any conditions added under section
|
224 |
// 7. This requirement modifies the requirement in section 4 to
|
225 |
// "keep intact all notices".
|
226 |
//
|
227 |
// c) You must license the entire work, as a whole, under this
|
228 |
// License to anyone who comes into possession of a copy. This
|
229 |
// License will therefore apply, along with any applicable section 7
|
230 |
// additional terms, to the whole of the work, and all its parts,
|
231 |
// regardless of how they are packaged. This License gives no
|
232 |
// permission to license the work in any other way, but it does not
|
233 |
// invalidate such permission if you have separately received it.
|
234 |
//
|
235 |
// d) If the work has interactive user interfaces, each must display
|
236 |
// Appropriate Legal Notices; however, if the Program has interactive
|
237 |
// interfaces that do not display Appropriate Legal Notices, your
|
238 |
// work need not make them do so.
|
239 |
//
|
240 |
// A compilation of a covered work with other separate and independent
|
241 |
//works, which are not by their nature extensions of the covered work,
|
242 |
//and which are not combined with it such as to form a larger program,
|
243 |
//in or on a volume of a storage or distribution medium, is called an
|
244 |
//"aggregate" if the compilation and its resulting copyright are not
|
245 |
//used to limit the access or legal rights of the compilation's users
|
246 |
//beyond what the individual works permit. Inclusion of a covered work
|
247 |
//in an aggregate does not cause this License to apply to the other
|
248 |
//parts of the aggregate.
|
249 |
//
|
250 |
// 6. Conveying Non-Source Forms.
|
251 |
//
|
252 |
// You may convey a covered work in object code form under the terms
|
253 |
//of sections 4 and 5, provided that you also convey the
|
254 |
//machine-readable Corresponding Source under the terms of this License,
|
255 |
//in one of these ways:
|
256 |
//
|
257 |
// a) Convey the object code in, or embodied in, a physical product
|
258 |
// (including a physical distribution medium), accompanied by the
|
259 |
// Corresponding Source fixed on a durable physical medium
|
260 |
// customarily used for software interchange.
|
261 |
//
|
262 |
// b) Convey the object code in, or embodied in, a physical product
|
263 |
// (including a physical distribution medium), accompanied by a
|
264 |
// written offer, valid for at least three years and valid for as
|
265 |
// long as you offer spare parts or customer support for that product
|
266 |
// model, to give anyone who possesses the object code either (1) a
|
267 |
// copy of the Corresponding Source for all the software in the
|
268 |
// product that is covered by this License, on a durable physical
|
269 |
// medium customarily used for software interchange, for a price no
|
270 |
// more than your reasonable cost of physically performing this
|
271 |
// conveying of source, or (2) access to copy the
|
272 |
// Corresponding Source from a network server at no charge.
|
273 |
//
|
274 |
// c) Convey individual copies of the object code with a copy of the
|
275 |
// written offer to provide the Corresponding Source. This
|
276 |
// alternative is allowed only occasionally and noncommercially, and
|
277 |
// only if you received the object code with such an offer, in accord
|
278 |
// with subsection 6b.
|
279 |
//
|
280 |
// d) Convey the object code by offering access from a designated
|
281 |
// place (gratis or for a charge), and offer equivalent access to the
|
282 |
// Corresponding Source in the same way through the same place at no
|
283 |
// further charge. You need not require recipients to copy the
|
284 |
// Corresponding Source along with the object code. If the place to
|
285 |
// copy the object code is a network server, the Corresponding Source
|
286 |
// may be on a different server (operated by you or a third party)
|
287 |
// that supports equivalent copying facilities, provided you maintain
|
288 |
// clear directions next to the object code saying where to find the
|
289 |
// Corresponding Source. Regardless of what server hosts the
|
290 |
// Corresponding Source, you remain obligated to ensure that it is
|
291 |
// available for as long as needed to satisfy these requirements.
|
292 |
//
|
293 |
// e) Convey the object code using peer-to-peer transmission, provided
|
294 |
// you inform other peers where the object code and Corresponding
|
295 |
// Source of the work are being offered to the general public at no
|
296 |
// charge under subsection 6d.
|
297 |
//
|
298 |
// A separable portion of the object code, whose source code is excluded
|
299 |
//from the Corresponding Source as a System Library, need not be
|
300 |
//included in conveying the object code work.
|
301 |
//
|
302 |
// A "User Product" is either (1) a "consumer product", which means any
|
303 |
//tangible personal property which is normally used for personal, family,
|
304 |
//or household purposes, or (2) anything designed or sold for incorporation
|
305 |
//into a dwelling. In determining whether a product is a consumer product,
|
306 |
//doubtful cases shall be resolved in favor of coverage. For a particular
|
307 |
//product received by a particular user, "normally used" refers to a
|
308 |
//typical or common use of that class of product, regardless of the status
|
309 |
//of the particular user or of the way in which the particular user
|
310 |
//actually uses, or expects or is expected to use, the product. A product
|
311 |
//is a consumer product regardless of whether the product has substantial
|
312 |
//commercial, industrial or non-consumer uses, unless such uses represent
|
313 |
//the only significant mode of use of the product.
|
314 |
//
|
315 |
// "Installation Information" for a User Product means any methods,
|
316 |
//procedures, authorization keys, or other information required to install
|
317 |
//and execute modified versions of a covered work in that User Product from
|
318 |
//a modified version of its Corresponding Source. The information must
|
319 |
//suffice to ensure that the continued functioning of the modified object
|
320 |
//code is in no case prevented or interfered with solely because
|
321 |
//modification has been made.
|
322 |
//
|
323 |
// If you convey an object code work under this section in, or with, or
|
324 |
//specifically for use in, a User Product, and the conveying occurs as
|
325 |
//part of a transaction in which the right of possession and use of the
|
326 |
//User Product is transferred to the recipient in perpetuity or for a
|
327 |
//fixed term (regardless of how the transaction is characterized), the
|
328 |
//Corresponding Source conveyed under this section must be accompanied
|
329 |
//by the Installation Information. But this requirement does not apply
|
330 |
//if neither you nor any third party retains the ability to install
|
331 |
//modified object code on the User Product (for example, the work has
|
332 |
//been installed in ROM).
|
333 |
//
|
334 |
// The requirement to provide Installation Information does not include a
|
335 |
//requirement to continue to provide support service, warranty, or updates
|
336 |
//for a work that has been modified or installed by the recipient, or for
|
337 |
//the User Product in which it has been modified or installed. Access to a
|
338 |
//network may be denied when the modification itself materially and
|
339 |
//adversely affects the operation of the network or violates the rules and
|
340 |
//protocols for communication across the network.
|
341 |
//
|
342 |
// Corresponding Source conveyed, and Installation Information provided,
|
343 |
//in accord with this section must be in a format that is publicly
|
344 |
//documented (and with an implementation available to the public in
|
345 |
//source code form), and must require no special password or key for
|
346 |
//unpacking, reading or copying.
|
347 |
//
|
348 |
// 7. Additional Terms.
|
349 |
//
|
350 |
// "Additional permissions" are terms that supplement the terms of this
|
351 |
//License by making exceptions from one or more of its conditions.
|
352 |
//Additional permissions that are applicable to the entire Program shall
|
353 |
//be treated as though they were included in this License, to the extent
|
354 |
//that they are valid under applicable law. If additional permissions
|
355 |
//apply only to part of the Program, that part may be used separately
|
356 |
//under those permissions, but the entire Program remains governed by
|
357 |
//this License without regard to the additional permissions.
|
358 |
//
|
359 |
// When you convey a copy of a covered work, you may at your option
|
360 |
//remove any additional permissions from that copy, or from any part of
|
361 |
//it. (Additional permissions may be written to require their own
|
362 |
//removal in certain cases when you modify the work.) You may place
|
363 |
//additional permissions on material, added by you to a covered work,
|
364 |
//for which you have or can give appropriate copyright permission.
|
365 |
//
|
366 |
// Notwithstanding any other provision of this License, for material you
|
367 |
//add to a covered work, you may (if authorized by the copyright holders of
|
368 |
//that material) supplement the terms of this License with terms:
|
369 |
//
|
370 |
// a) Disclaiming warranty or limiting liability differently from the
|
371 |
// terms of sections 15 and 16 of this License; or
|
372 |
//
|
373 |
// b) Requiring preservation of specified reasonable legal notices or
|
374 |
// author attributions in that material or in the Appropriate Legal
|
375 |
// Notices displayed by works containing it; or
|
376 |
//
|
377 |
// c) Prohibiting misrepresentation of the origin of that material, or
|
378 |
// requiring that modified versions of such material be marked in
|
379 |
// reasonable ways as different from the original version; or
|
380 |
//
|
381 |
// d) Limiting the use for publicity purposes of names of licensors or
|
382 |
// authors of the material; or
|
383 |
//
|
384 |
// e) Declining to grant rights under trademark law for use of some
|
385 |
// trade names, trademarks, or service marks; or
|
386 |
//
|
387 |
// f) Requiring indemnification of licensors and authors of that
|
388 |
// material by anyone who conveys the material (or modified versions of
|
389 |
// it) with contractual assumptions of liability to the recipient, for
|
390 |
// any liability that these contractual assumptions directly impose on
|
391 |
// those licensors and authors.
|
392 |
//
|
393 |
// All other non-permissive additional terms are considered "further
|
394 |
//restrictions" within the meaning of section 10. If the Program as you
|
395 |
//received it, or any part of it, contains a notice stating that it is
|
396 |
//governed by this License along with a term that is a further
|
397 |
//restriction, you may remove that term. If a license document contains
|
398 |
//a further restriction but permits relicensing or conveying under this
|
399 |
//License, you may add to a covered work material governed by the terms
|
400 |
//of that license document, provided that the further restriction does
|
401 |
//not survive such relicensing or conveying.
|
402 |
//
|
403 |
// If you add terms to a covered work in accord with this section, you
|
404 |
//must place, in the relevant source files, a statement of the
|
405 |
//additional terms that apply to those files, or a notice indicating
|
406 |
//where to find the applicable terms.
|
407 |
//
|
408 |
// Additional terms, permissive or non-permissive, may be stated in the
|
409 |
//form of a separately written license, or stated as exceptions;
|
410 |
//the above requirements apply either way.
|
411 |
//
|
412 |
// 8. Termination.
|
413 |
//
|
414 |
// You may not propagate or modify a covered work except as expressly
|
415 |
//provided under this License. Any attempt otherwise to propagate or
|
416 |
//modify it is void, and will automatically terminate your rights under
|
417 |
//this License (including any patent licenses granted under the third
|
418 |
//paragraph of section 11).
|
419 |
//
|
420 |
// However, if you cease all violation of this License, then your
|
421 |
//license from a particular copyright holder is reinstated (a)
|
422 |
//provisionally, unless and until the copyright holder explicitly and
|
423 |
//finally terminates your license, and (b) permanently, if the copyright
|
424 |
//holder fails to notify you of the violation by some reasonable means
|
425 |
//prior to 60 days after the cessation.
|
426 |
//
|
427 |
// Moreover, your license from a particular copyright holder is
|
428 |
//reinstated permanently if the copyright holder notifies you of the
|
429 |
//violation by some reasonable means, this is the first time you have
|
430 |
//received notice of violation of this License (for any work) from that
|
431 |
//copyright holder, and you cure the violation prior to 30 days after
|
432 |
//your receipt of the notice.
|
433 |
//
|
434 |
// Termination of your rights under this section does not terminate the
|
435 |
//licenses of parties who have received copies or rights from you under
|
436 |
//this License. If your rights have been terminated and not permanently
|
437 |
//reinstated, you do not qualify to receive new licenses for the same
|
438 |
//material under section 10.
|
439 |
//
|
440 |
// 9. Acceptance Not Required for Having Copies.
|
441 |
//
|
442 |
// You are not required to accept this License in order to receive or
|
443 |
//run a copy of the Program. Ancillary propagation of a covered work
|
444 |
//occurring solely as a consequence of using peer-to-peer transmission
|
445 |
//to receive a copy likewise does not require acceptance. However,
|
446 |
//nothing other than this License grants you permission to propagate or
|
447 |
//modify any covered work. These actions infringe copyright if you do
|
448 |
//not accept this License. Therefore, by modifying or propagating a
|
449 |
//covered work, you indicate your acceptance of this License to do so.
|
450 |
//
|
451 |
// 10. Automatic Licensing of Downstream Recipients.
|
452 |
//
|
453 |
// Each time you convey a covered work, the recipient automatically
|
454 |
//receives a license from the original licensors, to run, modify and
|
455 |
//propagate that work, subject to this License. You are not responsible
|
456 |
//for enforcing compliance by third parties with this License.
|
457 |
//
|
458 |
// An "entity transaction" is a transaction transferring control of an
|
459 |
//organization, or substantially all assets of one, or subdividing an
|
460 |
//organization, or merging organizations. If propagation of a covered
|
461 |
//work results from an entity transaction, each party to that
|
462 |
//transaction who receives a copy of the work also receives whatever
|
463 |
//licenses to the work the party's predecessor in interest had or could
|
464 |
//give under the previous paragraph, plus a right to possession of the
|
465 |
//Corresponding Source of the work from the predecessor in interest, if
|
466 |
//the predecessor has it or can get it with reasonable efforts.
|
467 |
//
|
468 |
// You may not impose any further restrictions on the exercise of the
|
469 |
//rights granted or affirmed under this License. For example, you may
|
470 |
//not impose a license fee, royalty, or other charge for exercise of
|
471 |
//rights granted under this License, and you may not initiate litigation
|
472 |
//(including a cross-claim or counterclaim in a lawsuit) alleging that
|
473 |
//any patent claim is infringed by making, using, selling, offering for
|
474 |
//sale, or importing the Program or any portion of it.
|
475 |
//
|
476 |
// 11. Patents.
|
477 |
//
|
478 |
// A "contributor" is a copyright holder who authorizes use under this
|
479 |
//License of the Program or a work on which the Program is based. The
|
480 |
//work thus licensed is called the contributor's "contributor version".
|
481 |
//
|
482 |
// A contributor's "essential patent claims" are all patent claims
|
483 |
//owned or controlled by the contributor, whether already acquired or
|
484 |
//hereafter acquired, that would be infringed by some manner, permitted
|
485 |
//by this License, of making, using, or selling its contributor version,
|
486 |
//but do not include claims that would be infringed only as a
|
487 |
//consequence of further modification of the contributor version. For
|
488 |
//purposes of this definition, "control" includes the right to grant
|
489 |
//patent sublicenses in a manner consistent with the requirements of
|
490 |
//this License.
|
491 |
//
|
492 |
// Each contributor grants you a non-exclusive, worldwide, royalty-free
|
493 |
//patent license under the contributor's essential patent claims, to
|
494 |
//make, use, sell, offer for sale, import and otherwise run, modify and
|
495 |
//propagate the contents of its contributor version.
|
496 |
//
|
497 |
// In the following three paragraphs, a "patent license" is any express
|
498 |
//agreement or commitment, however denominated, not to enforce a patent
|
499 |
//(such as an express permission to practice a patent or covenant not to
|
500 |
//sue for patent infringement). To "grant" such a patent license to a
|
501 |
//party means to make such an agreement or commitment not to enforce a
|
502 |
//patent against the party.
|
503 |
//
|
504 |
// If you convey a covered work, knowingly relying on a patent license,
|
505 |
//and the Corresponding Source of the work is not available for anyone
|
506 |
//to copy, free of charge and under the terms of this License, through a
|
507 |
//publicly available network server or other readily accessible means,
|
508 |
//then you must either (1) cause the Corresponding Source to be so
|
509 |
//available, or (2) arrange to deprive yourself of the benefit of the
|
510 |
//patent license for this particular work, or (3) arrange, in a manner
|
511 |
//consistent with the requirements of this License, to extend the patent
|
512 |
//license to downstream recipients. "Knowingly relying" means you have
|
513 |
//actual knowledge that, but for the patent license, your conveying the
|
514 |
//covered work in a country, or your recipient's use of the covered work
|
515 |
//in a country, would infringe one or more identifiable patents in that
|
516 |
//country that you have reason to believe are valid.
|
517 |
//
|
518 |
// If, pursuant to or in connection with a single transaction or
|
519 |
//arrangement, you convey, or propagate by procuring conveyance of, a
|
520 |
//covered work, and grant a patent license to some of the parties
|
521 |
//receiving the covered work authorizing them to use, propagate, modify
|
522 |
//or convey a specific copy of the covered work, then the patent license
|
523 |
//you grant is automatically extended to all recipients of the covered
|
524 |
//work and works based on it.
|
525 |
//
|
526 |
// A patent license is "discriminatory" if it does not include within
|
527 |
//the scope of its coverage, prohibits the exercise of, or is
|
528 |
//conditioned on the non-exercise of one or more of the rights that are
|
529 |
//specifically granted under this License. You may not convey a covered
|
530 |
//work if you are a party to an arrangement with a third party that is
|
531 |
//in the business of distributing software, under which you make payment
|
532 |
//to the third party based on the extent of your activity of conveying
|
533 |
//the work, and under which the third party grants, to any of the
|
534 |
//parties who would receive the covered work from you, a discriminatory
|
535 |
//patent license (a) in connection with copies of the covered work
|
536 |
//conveyed by you (or copies made from those copies), or (b) primarily
|
537 |
//for and in connection with specific products or compilations that
|
538 |
//contain the covered work, unless you entered into that arrangement,
|
539 |
//or that patent license was granted, prior to 28 March 2007.
|
540 |
//
|
541 |
// Nothing in this License shall be construed as excluding or limiting
|
542 |
//any implied license or other defenses to infringement that may
|
543 |
//otherwise be available to you under applicable patent law.
|
544 |
//
|
545 |
// 12. No Surrender of Others' Freedom.
|
546 |
//
|
547 |
// If conditions are imposed on you (whether by court order, agreement or
|
548 |
//otherwise) that contradict the conditions of this License, they do not
|
549 |
//excuse you from the conditions of this License. If you cannot convey a
|
550 |
//covered work so as to satisfy simultaneously your obligations under this
|
551 |
//License and any other pertinent obligations, then as a consequence you may
|
552 |
//not convey it at all. For example, if you agree to terms that obligate you
|
553 |
//to collect a royalty for further conveying from those to whom you convey
|
554 |
//the Program, the only way you could satisfy both those terms and this
|
555 |
//License would be to refrain entirely from conveying the Program.
|
556 |
//
|
557 |
// 13. Use with the GNU Affero General Public License.
|
558 |
//
|
559 |
// Notwithstanding any other provision of this License, you have
|
560 |
//permission to link or combine any covered work with a work licensed
|
561 |
//under version 3 of the GNU Affero General Public License into a single
|
562 |
//combined work, and to convey the resulting work. The terms of this
|
563 |
//License will continue to apply to the part which is the covered work,
|
564 |
//but the special requirements of the GNU Affero General Public License,
|
565 |
//section 13, concerning interaction through a network will apply to the
|
566 |
//combination as such.
|
567 |
//
|
568 |
// 14. Revised Versions of this License.
|
569 |
//
|
570 |
// The Free Software Foundation may publish revised and/or new versions of
|
571 |
//the GNU General Public License from time to time. Such new versions will
|
572 |
//be similar in spirit to the present version, but may differ in detail to
|
573 |
//address new problems or concerns.
|
574 |
//
|
575 |
// Each version is given a distinguishing version number. If the
|
576 |
//Program specifies that a certain numbered version of the GNU General
|
577 |
//Public License "or any later version" applies to it, you have the
|
578 |
//option of following the terms and conditions either of that numbered
|
579 |
//version or of any later version published by the Free Software
|
580 |
//Foundation. If the Program does not specify a version number of the
|
581 |
//GNU General Public License, you may choose any version ever published
|
582 |
//by the Free Software Foundation.
|
583 |
//
|
584 |
// If the Program specifies that a proxy can decide which future
|
585 |
//versions of the GNU General Public License can be used, that proxy's
|
586 |
//public statement of acceptance of a version permanently authorizes you
|
587 |
//to choose that version for the Program.
|
588 |
//
|
589 |
// Later license versions may give you additional or different
|
590 |
//permissions. However, no additional obligations are imposed on any
|
591 |
//author or copyright holder as a result of your choosing to follow a
|
592 |
//later version.
|
593 |
//
|
594 |
// 15. Disclaimer of Warranty.
|
595 |
//
|
596 |
// THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
|
597 |
//APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
|
598 |
//HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
|
599 |
//OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
|
600 |
//THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
|
601 |
//PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
|
602 |
//IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
|
603 |
//ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
|
604 |
//
|
605 |
// 16. Limitation of Liability.
|
606 |
//
|
607 |
// IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
|
608 |
//WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
|
609 |
//THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
|
610 |
//GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
|
611 |
//USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
|
612 |
//DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
|
613 |
//PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
|
614 |
//EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
|
615 |
//SUCH DAMAGES.
|
616 |
//
|
617 |
// 17. Interpretation of Sections 15 and 16.
|
618 |
//
|
619 |
// If the disclaimer of warranty and limitation of liability provided
|
620 |
//above cannot be given local legal effect according to their terms,
|
621 |
//reviewing courts shall apply local law that most closely approximates
|
622 |
//an absolute waiver of all civil liability in connection with the
|
623 |
//Program, unless a warranty or assumption of liability accompanies a
|
624 |
//copy of the Program in return for a fee.
|
625 |
//
|
626 |
// END OF TERMS AND CONDITIONS
|
627 |
//
|
628 |
// How to Apply These Terms to Your New Programs
|
629 |
//
|
630 |
// If you develop a new program, and you want it to be of the greatest
|
631 |
//possible use to the public, the best way to achieve this is to make it
|
632 |
//free software which everyone can redistribute and change under these terms.
|
633 |
//
|
634 |
// To do so, attach the following notices to the program. It is safest
|
635 |
//to attach them to the start of each source file to most effectively
|
636 |
//state the exclusion of warranty; and each file should have at least
|
637 |
//the "copyright" line and a pointer to where the full notice is found.
|
638 |
//
|
639 |
// <one line to give the program's name and a brief idea of what it does.>
