Everyone is permitted to copy and distribute verbatim copies |
16 |
of this license document, but changing it is not allowed.</p>
|
17 |
|

<h3><a name="preamble"></a>Preamble</h3> |
19 |
|
20 |
<p>The GNU General Public License is a free, copyleft license for
|
21 |
software and other kinds of works.</p>
|
22 |
|
23 |
<p>The licenses for most software and other practical works are designed
|
24 |
to take away your freedom to share and change the works. By contrast, |
25 |
the GNU General Public License is intended to guarantee your freedom to |
26 |
share and change all versions of a program--to make sure it remains free |
27 |
software for all its users. We, the Free Software Foundation, use the |
28 |
GNU General Public License for most of our software; it applies also to |
29 |
any other work released this way by its authors. You can apply it to |
30 |
your programs, too.</p>
|
31 |
|
32 |
<p>When we speak of free software, we are referring to freedom, not
|
33 |
price. Our General Public Licenses are designed to make sure that you |
34 |
have the freedom to distribute copies of free software (and charge for |
35 |
them if you wish), that you receive source code or can get it if you |
36 |
want it, that you can change the software or use pieces of it in new |
37 |
free programs, and that you know you can do these things.</p>
|
38 |
|
39 |
<p>To protect your rights, we need to prevent others from denying you
|
40 |
these rights or asking you to surrender the rights. Therefore, you have |
41 |
certain responsibilities if you distribute copies of the software, or if |
42 |
you modify it: responsibilities to respect the freedom of others.</p>
|
43 |
|
44 |
<p>For example, if you distribute copies of such a program, whether
|
45 |
gratis or for a fee, you must pass on to the recipients the same |
46 |
freedoms that you received. You must make sure that they, too, receive |
47 |
or can get the source code. And you must show them these terms so they |
48 |
know their rights.</p>
|
49 |
|
50 |
<p>Developers that use the GNU GPL protect your rights with two steps:
|
51 |
(1) assert copyright on the software, and (2) offer you this License |
52 |
giving you legal permission to copy, distribute and/or modify it.</p>
|
53 |
|
54 |
<p>For the developers' and authors' protection, the GPL clearly explains
|
55 |
that there is no warranty for this free software. For both users' and |
56 |
authors' sake, the GPL requires that modified versions be marked as |
57 |
changed, so that their problems will not be attributed erroneously to |
58 |
authors of previous versions.</p>
|
59 |
|
60 |
<p>Some devices are designed to deny users access to install or run
|
61 |
modified versions of the software inside them, although the manufacturer |
62 |
can do so. This is fundamentally incompatible with the aim of |
63 |
protecting users' freedom to change the software. The systematic |
64 |
pattern of such abuse occurs in the area of products for individuals to |
65 |
use, which is precisely where it is most unacceptable. Therefore, we |
66 |
have designed this version of the GPL to prohibit the practice for those |
67 |
products. If such problems arise substantially in other domains, we |
68 |
stand ready to extend this provision to those domains in future versions |
69 |
of the GPL, as needed to protect the freedom of users.</p>
|
70 |
|
71 |
<p>Finally, every program is threatened constantly by software patents.
|
72 |
States should not allow patents to restrict development and use of |
73 |
software on general-purpose computers, but in those that do, we wish to |
74 |
avoid the special danger that patents applied to a free program could |
75 |
make it effectively proprietary. To prevent this, the GPL assures that |
76 |
patents cannot be used to render the program non-free.</p>
|
77 |
|
78 |
<p>The precise terms and conditions for copying, distribution and
|
79 |
modification follow.</p>
|
80 |
|
81 |
<h3><a name="terms"></a>TERMS AND CONDITIONS</h3> |
82 |
|
83 |
<h4><a name="section0"></a>0. Definitions.</h4> |
84 |
|
85 |
<p>“This License” refers to version 3 of the GNU General Public License.</p> |
86 |
|
87 |
<p>“Copyright” also means copyright-like laws that apply to other kinds of
|
88 |
works, such as semiconductor masks.</p>
|
89 |
|
90 |
<p>“The Program” refers to any copyrightable work licensed under this
|
91 |
License. Each licensee is addressed as “you”. “Licensees” and |
92 |
“recipients” may be individuals or organizations.</p>
|
93 |
|
94 |
<p>To “modify” a work means to copy from or adapt all or part of the work
|
95 |
in a fashion requiring copyright permission, other than the making of an |
96 |
exact copy. The resulting work is called a “modified version” of the |
97 |
earlier work or a work “based on” the earlier work.</p>
|
98 |
|
99 |
<p>A “covered work” means either the unmodified Program or a work based
|
100 |
on the Program.</p>
|
101 |
|
102 |
<p>To “propagate” a work means to do anything with it that, without
|
103 |
permission, would make you directly or secondarily liable for |
104 |
infringement under applicable copyright law, except executing it on a |
105 |
computer or modifying a private copy. Propagation includes copying, |
106 |
distribution (with or without modification), making available to the |
107 |
public, and in some countries other activities as well.</p>
|
108 |
|
109 |
<p>To “convey” a work means any kind of propagation that enables other
|
110 |
parties to make or receive copies. Mere interaction with a user through |
111 |
a computer network, with no transfer of a copy, is not conveying.</p>
|
112 |
|
113 |
<p>An interactive user interface displays “Appropriate Legal Notices”
|
114 |
to the extent that it includes a convenient and prominently visible |
115 |
feature that (1) displays an appropriate copyright notice, and (2) |
116 |
tells the user that there is no warranty for the work (except to the |
117 |
extent that warranties are provided), that licensees may convey the |
118 |
work under this License, and how to view a copy of this License. If |
119 |
the interface presents a list of user commands or options, such as a |
120 |
menu, a prominent item in the list meets this criterion.</p>
|
121 |
|
122 |
<h4><a name="section1"></a>1. Source Code.</h4> |
123 |
|
124 |
<p>The “source code” for a work means the preferred form of the work
|
125 |
for making modifications to it. “Object code” means any non-source |
126 |
form of a work.</p>
|
127 |
|
128 |
<p>A “Standard Interface” means an interface that either is an official
|
129 |
standard defined by a recognized standards body, or, in the case of |
130 |
interfaces specified for a particular programming language, one that |
131 |
is widely used among developers working in that language.</p>
|
132 |
|
133 |
<p>The “System Libraries” of an executable work include anything, other
|
134 |
than the work as a whole, that (a) is included in the normal form of |
135 |
packaging a Major Component, but which is not part of that Major |
136 |
Component, and (b) serves only to enable use of the work with that |
137 |
Major Component, or to implement a Standard Interface for which an |
138 |
implementation is available to the public in source code form. A |
139 |
“Major Component”, in this context, means a major essential component |
140 |
(kernel, window system, and so on) of the specific operating system |
141 |
(if any) on which the executable work runs, or a compiler used to |
142 |
produce the work, or an object code interpreter used to run it.</p>
|
143 |
|
144 |
<p>The “Corresponding Source” for a work in object code form means all
|
145 |
the source code needed to generate, install, and (for an executable |
146 |
work) run the object code and to modify the work, including scripts to |
147 |
control those activities. However, it does not include the work's |
148 |
System Libraries, or general-purpose tools or generally available free |
149 |
programs which are used unmodified in performing those activities but |
150 |
which are not part of the work. For example, Corresponding Source |
151 |
includes interface definition files associated with source files for |
152 |
the work, and the source code for shared libraries and dynamically |
153 |
linked subprograms that the work is specifically designed to require, |
154 |
such as by intimate data communication or control flow between those |
155 |
subprograms and other parts of the work.</p>
|
156 |
|
157 |
<p>The Corresponding Source need not include anything that users
|
158 |
can regenerate automatically from other parts of the Corresponding |
159 |
Source.</p>
|
160 |
|
161 |
<p>The Corresponding Source for a work in source code form is that
|
162 |
same work.</p>
|
163 |
|
164 |
<h4><a name="section2"></a>2. Basic Permissions.</h4> |
165 |
|
166 |
<p>All rights granted under this License are granted for the term of
|
167 |
copyright on the Program, and are irrevocable provided the stated |
168 |
conditions are met. This License explicitly affirms your unlimited |
169 |
permission to run the unmodified Program. The output from running a |
170 |
covered work is covered by this License only if the output, given its |
171 |
content, constitutes a covered work. This License acknowledges your |
172 |
rights of fair use or other equivalent, as provided by copyright law.</p>
|
173 |
|
174 |
<p>You may make, run and propagate covered works that you do not
|
175 |
convey, without conditions so long as your license otherwise remains |
176 |
in force. You may convey covered works to others for the sole purpose |
177 |
of having them make modifications exclusively for you, or provide you |
178 |
with facilities for running those works, provided that you comply with |
179 |
the terms of this License in conveying all material for which you do |
180 |
not control copyright. Those thus making or running the covered works |
181 |
for you must do so exclusively on your behalf, under your direction |
182 |
and control, on terms that prohibit them from making any copies of |
183 |
your copyrighted material outside their relationship with you.</p>
|
184 |
|
185 |
<p>Conveying under any other circumstances is permitted solely under
|
186 |
the conditions stated below. Sublicensing is not allowed; section 10 |
187 |
makes it unnecessary.</p>
|
188 |
|
189 |
<h4><a name="section3"></a>3. Protecting Users' Legal Rights From Anti-Circumvention Law.</h4> |
190 |
|
191 |
<p>No covered work shall be deemed part of an effective technological
|
192 |
measure under any applicable law fulfilling obligations under article |
193 |
11 of the WIPO copyright treaty adopted on 20 December 1996, or |
194 |
similar laws prohibiting or restricting circumvention of such |
195 |
measures.</p>
|
196 |
|
197 |
<p>When you convey a covered work, you waive any legal power to forbid
|
198 |
circumvention of technological measures to the extent such circumvention |
199 |
is effected by exercising rights under this License with respect to |
200 |
the covered work, and you disclaim any intention to limit operation or |
201 |
modification of the work as a means of enforcing, against the work's |
202 |
users, your or third parties' legal rights to forbid circumvention of |
203 |
technological measures.</p>
|
204 |
|
205 |
<h4><a name="section4"></a>4. Conveying Verbatim Copies.</h4> |
206 |
|
207 |
<p>You may convey verbatim copies of the Program's source code as you
|
208 |
receive it, in any medium, provided that you conspicuously and |
209 |
appropriately publish on each copy an appropriate copyright notice; |
210 |
keep intact all notices stating that this License and any |
211 |
non-permissive terms added in accord with section 7 apply to the code; |
212 |
keep intact all notices of the absence of any warranty; and give all |
213 |
recipients a copy of this License along with the Program.</p>
|
214 |
|
215 |
<p>You may charge any price or no price for each copy that you convey,
|
216 |
and you may offer support or warranty protection for a fee.</p>
|
217 |
|
218 |
<h4><a name="section5"></a>5. Conveying Modified Source Versions.</h4> |
219 |
|
220 |
<p>You may convey a work based on the Program, or the modifications to
|
221 |
produce it from the Program, in the form of source code under the |
222 |
terms of section 4, provided that you also meet all of these conditions:</p>
|
223 |
|
224 |
<ul>
|
225 |
<li>a) The work must carry prominent notices stating that you modified
|
226 |
it, and giving a relevant date.</li>
|
227 |
|
228 |
<li>b) The work must carry prominent notices stating that it is
|
229 |
released under this License and any conditions added under section |
230 |
7. This requirement modifies the requirement in section 4 to |
231 |
“keep intact all notices”.</li>
|
232 |
|
233 |
<li>c) You must license the entire work, as a whole, under this
|
234 |
License to anyone who comes into possession of a copy. This |
235 |
License will therefore apply, along with any applicable section 7 |
236 |
additional terms, to the whole of the work, and all its parts, |
237 |
regardless of how they are packaged. This License gives no |
238 |
permission to license the work in any other way, but it does not |
239 |
invalidate such permission if you have separately received it.</li>
|
240 |
|
241 |
<li>d) If the work has interactive user interfaces, each must display
|
242 |
Appropriate Legal Notices; however, if the Program has interactive |
243 |
interfaces that do not display Appropriate Legal Notices, your |
244 |
work need not make them do so.</li>
|
245 |
</ul>
|
246 |
|
247 |
<p>A compilation of a covered work with other separate and independent
|
248 |
works, which are not by their nature extensions of the covered work, |
249 |
and which are not combined with it such as to form a larger program, |
250 |
in or on a volume of a storage or distribution medium, is called an |
251 |
“aggregate” if the compilation and its resulting copyright are not |
252 |
used to limit the access or legal rights of the compilation's users |
253 |
beyond what the individual works permit. Inclusion of a covered work |
254 |
in an aggregate does not cause this License to apply to the other |
255 |
parts of the aggregate.</p>
|
256 |
|
257 |
<h4><a name="section6"></a>6. Conveying Non-Source Forms.</h4> |
258 |
|
259 |
<p>You may convey a covered work in object code form under the terms
|
260 |
of sections 4 and 5, provided that you also convey the |
261 |
machine-readable Corresponding Source under the terms of this License, |
262 |
in one of these ways:</p>
|
263 |
|
264 |
<ul>
|
265 |
<li>a) Convey the object code in, or embodied in, a physical product
|
266 |
(including a physical distribution medium), accompanied by the |
267 |
Corresponding Source fixed on a durable physical medium |
268 |
customarily used for software interchange.</li>
|
269 |
|
270 |
<li>b) Convey the object code in, or embodied in, a physical product
|
271 |
(including a physical distribution medium), accompanied by a |
272 |
written offer, valid for at least three years and valid for as |
273 |
long as you offer spare parts or customer support for that product |
274 |
model, to give anyone who possesses the object code either (1) a |
275 |
copy of the Corresponding Source for all the software in the |
276 |
product that is covered by this License, on a durable physical |
277 |
medium customarily used for software interchange, for a price no |
278 |
more than your reasonable cost of physically performing this |
279 |
conveying of source, or (2) access to copy the |
280 |
Corresponding Source from a network server at no charge.</li>
|
281 |
|
282 |
<li>c) Convey individual copies of the object code with a copy of the
|
283 |
written offer to provide the Corresponding Source. This |
284 |
alternative is allowed only occasionally and noncommercially, and |
285 |
only if you received the object code with such an offer, in accord |
286 |
with subsection 6b.</li>
|
287 |
|
288 |
<li>d) Convey the object code by offering access from a designated
|
289 |
place (gratis or for a charge), and offer equivalent access to the |
290 |
Corresponding Source in the same way through the same place at no |
291 |
further charge. You need not require recipients to copy the |
292 |
Corresponding Source along with the object code. If the place to |
293 |
copy the object code is a network server, the Corresponding Source |
294 |
may be on a different server (operated by you or a third party) |
295 |
that supports equivalent copying facilities, provided you maintain |
296 |
clear directions next to the object code saying where to find the |
297 |
Corresponding Source. Regardless of what server hosts the |
298 |
Corresponding Source, you remain obligated to ensure that it is |
299 |
available for as long as needed to satisfy these requirements.</li>
|
300 |
|
301 |
<li>e) Convey the object code using peer-to-peer transmission, provided
|
302 |
you inform other peers where the object code and Corresponding |
303 |
Source of the work are being offered to the general public at no |
304 |
charge under subsection 6d.</li>
|
305 |
</ul>
|
306 |
|
307 |
<p>A separable portion of the object code, whose source code is excluded
|
308 |
from the Corresponding Source as a System Library, need not be |
309 |
included in conveying the object code work.</p>
|
310 |
|
311 |
<p>A “User Product” is either (1) a “consumer product”, which means any
|
312 |
tangible personal property which is normally used for personal, family, |
313 |
or household purposes, or (2) anything designed or sold for incorporation |
314 |
into a dwelling. In determining whether a product is a consumer product, |
315 |
doubtful cases shall be resolved in favor of coverage. For a particular |
316 |
product received by a particular user, “normally used” refers to a |
317 |
typical or common use of that class of product, regardless of the status |
318 |
of the particular user or of the way in which the particular user |
319 |
actually uses, or expects or is expected to use, the product. A product |
320 |
is a consumer product regardless of whether the product has substantial |
321 |
commercial, industrial or non-consumer uses, unless such uses represent |
322 |
the only significant mode of use of the product.</p>
|
323 |
|
324 |
<p>“Installation Information” for a User Product means any methods,
|
325 |
procedures, authorization keys, or other information required to install |
326 |
and execute modified versions of a covered work in that User Product from |
327 |
a modified version of its Corresponding Source. The information must |
328 |
suffice to ensure that the continued functioning of the modified object |
329 |
code is in no case prevented or interfered with solely because |
330 |
modification has been made.</p>
|
331 |
|
332 |
<p>If you convey an object code work under this section in, or with, or
|
333 |
specifically for use in, a User Product, and the conveying occurs as |
334 |
part of a transaction in which the right of possession and use of the |
335 |
User Product is transferred to the recipient in perpetuity or for a |
336 |
fixed term (regardless of how the transaction is characterized), the |
337 |
Corresponding Source conveyed under this section must be accompanied |
338 |
by the Installation Information. But this requirement does not apply |
339 |
if neither you nor any third party retains the ability to install |
340 |
modified object code on the User Product (for example, the work has |
341 |
been installed in ROM).</p>
|
342 |
|
343 |
<p>The requirement to provide Installation Information does not include a
|
344 |
requirement to continue to provide support service, warranty, or updates |
345 |
for a work that has been modified or installed by the recipient, or for |
346 |
the User Product in which it has been modified or installed. Access to a |
347 |
network may be denied when the modification itself materially and |
348 |
adversely affects the operation of the network or violates the rules and |
349 |
protocols for communication across the network.</p>
|
350 |
|
351 |
<p>Corresponding Source conveyed, and Installation Information provided,
|
352 |
in accord with this section must be in a format that is publicly |
353 |
documented (and with an implementation available to the public in |
354 |
source code form), and must require no special password or key for |
355 |
unpacking, reading or copying.</p>
|
356 |
|
357 |
<h4><a name="section7"></a>7. Additional Terms.</h4> |
358 |
|
359 |
<p>“Additional permissions” are terms that supplement the terms of this
|
360 |
License by making exceptions from one or more of its conditions. |
361 |
Additional permissions that are applicable to the entire Program shall |
362 |
be treated as though they were included in this License, to the extent |
363 |
that they are valid under applicable law. If additional permissions |
364 |
apply only to part of the Program, that part may be used separately |
365 |
under those permissions, but the entire Program remains governed by |
366 |
this License without regard to the additional permissions.</p>
|
367 |
|
368 |
<p>When you convey a copy of a covered work, you may at your option
|
369 |
remove any additional permissions from that copy, or from any part of |
370 |
it. (Additional permissions may be written to require their own |
371 |
removal in certain cases when you modify the work.) You may place |
372 |
additional permissions on material, added by you to a covered work, |
373 |
for which you have or can give appropriate copyright permission.</p>
|
374 |
|
375 |
<p>Notwithstanding any other provision of this License, for material you
|
376 |
add to a covered work, you may (if authorized by the copyright holders of |
377 |
that material) supplement the terms of this License with terms:</p>
|
378 |
|
379 |
<ul>
|
380 |
<li>a) Disclaiming warranty or limiting liability differently from the
|
381 |
terms of sections 15 and 16 of this License; or</li>
|
382 |
|
383 |
<li>b) Requiring preservation of specified reasonable legal notices or

those licensors and authors.</li>

</ul>
|
403 |
|
404 |
<p>All other non-permissive additional terms are considered “further
|
405 |
restrictions” within the meaning of section 10. If the Program as you |
406 |
received it, or any part of it, contains a notice stating that it is |
407 |
governed by this License along with a term that is a further |
408 |
restriction, you may remove that term. If a license document contains |
409 |
a further restriction but permits relicensing or conveying under this |
410 |
License, you may add to a covered work material governed by the terms |
411 |
of that license document, provided that the further restriction does |
412 |
not survive such relicensing or conveying.</p>
|
413 |
|
414 |
<p>If you add terms to a covered work in accord with this section, you
|
415 |
must place, in the relevant source files, a statement of the |
416 |
additional terms that apply to those files, or a notice indicating |
417 |
where to find the applicable terms.</p>
|
418 |
|
419 |
<p>Additional terms, permissive or non-permissive, may be stated in the
|
420 |
form of a separately written license, or stated as exceptions; |
421 |
the above requirements apply either way.</p>
|
422 |
|
423 |
<h4><a name="section8"></a>8. Termination.</h4> |
424 |
|
425 |
<p>You may not propagate or modify a covered work except as expressly
|
426 |
provided under this License. Any attempt otherwise to propagate or |
427 |
modify it is void, and will automatically terminate your rights under |
428 |
this License (including any patent licenses granted under the third |
429 |
paragraph of section 11).</p>
|
430 |
|
431 |
<p>However, if you cease all violation of this License, then your
|
432 |
license from a particular copyright holder is reinstated (a) |
433 |
provisionally, unless and until the copyright holder explicitly and |
434 |
finally terminates your license, and (b) permanently, if the copyright |
435 |
holder fails to notify you of the violation by some reasonable means |
436 |
prior to 60 days after the cessation.</p>
|
437 |
|
438 |
<p>Moreover, your license from a particular copyright holder is
|
439 |
reinstated permanently if the copyright holder notifies you of the |
440 |
violation by some reasonable means, this is the first time you have |
441 |
received notice of violation of this License (for any work) from that |
442 |
copyright holder, and you cure the violation prior to 30 days after |
443 |
your receipt of the notice.</p>
|
444 |
|
445 |
<p>Termination of your rights under this section does not terminate the
|
446 |
licenses of parties who have received copies or rights from you under |
447 |
this License. If your rights have been terminated and not permanently |
448 |
reinstated, you do not qualify to receive new licenses for the same |
449 |
material under section 10.</p>
|
450 |
|
451 |
<h4><a name="section9"></a>9. Acceptance Not Required for Having Copies.</h4> |
452 |
|
453 |
<p>You are not required to accept this License in order to receive or
|
454 |
run a copy of the Program. Ancillary propagation of a covered work |
455 |
occurring solely as a consequence of using peer-to-peer transmission |
456 |
to receive a copy likewise does not require acceptance. However, |
457 |
nothing other than this License grants you permission to propagate or |
458 |
modify any covered work. These actions infringe copyright if you do |
459 |
not accept this License. Therefore, by modifying or propagating a |
460 |
covered work, you indicate your acceptance of this License to do so.</p>
|
461 |
|
462 |
<h4><a name="section10"></a>10. Automatic Licensing of Downstream Recipients.</h4> |
463 |
|
464 |
<p>Each time you convey a covered work, the recipient automatically
|
465 |
receives a license from the original licensors, to run, modify and |
466 |
propagate that work, subject to this License. You are not responsible |
467 |
for enforcing compliance by third parties with this License.</p>
|
468 |
|
469 |
<p>An “entity transaction” is a transaction transferring control of an
|
470 |
organization, or substantially all assets of one, or subdividing an |
471 |
organization, or merging organizations. If propagation of a covered |
472 |
work results from an entity transaction, each party to that |
473 |
transaction who receives a copy of the work also receives whatever |
474 |
licenses to the work the party's predecessor in interest had or could |
475 |
give under the previous paragraph, plus a right to possession of the |
476 |
Corresponding Source of the work from the predecessor in interest, if |
477 |
the predecessor has it or can get it with reasonable efforts.</p>
|
478 |
|
479 |
<p>You may not impose any further restrictions on the exercise of the
|
480 |
rights granted or affirmed under this License. For example, you may |
481 |
not impose a license fee, royalty, or other charge for exercise of |
482 |
rights granted under this License, and you may not initiate litigation |
483 |
(including a cross-claim or counterclaim in a lawsuit) alleging that |
484 |
any patent claim is infringed by making, using, selling, offering for |
485 |
sale, or importing the Program or any portion of it.</p>
|
486 |
|
487 |
<h4><a name="section11"></a>11. Patents.</h4> |
488 |
|
489 |
<p>A “contributor” is a copyright holder who authorizes use under this
|
490 |
License of the Program or a work on which the Program is based. The |
491 |
work thus licensed is called the contributor's “contributor version”.</p>
|
492 |
|
493 |
<p>A contributor's “essential patent claims” are all patent claims
|
494 |
owned or controlled by the contributor, whether already acquired or |
495 |
hereafter acquired, that would be infringed by some manner, permitted |
496 |
by this License, of making, using, or selling its contributor version, |
497 |
but do not include claims that would be infringed only as a |
498 |
consequence of further modification of the contributor version. For |
499 |
purposes of this definition, “control” includes the right to grant |
500 |
patent sublicenses in a manner consistent with the requirements of |
501 |
this License.</p>
|
502 |
|
503 |
<p>Each contributor grants you a non-exclusive, worldwide, royalty-free
|
504 |
patent license under the contributor's essential patent claims, to |
505 |
make, use, sell, offer for sale, import and otherwise run, modify and |
506 |
propagate the contents of its contributor version.</p>
|
507 |
|
508 |
<p>In the following three paragraphs, a “patent license” is any express
|
509 |
agreement or commitment, however denominated, not to enforce a patent |
510 |
(such as an express permission to practice a patent or covenant not to |
511 |
sue for patent infringement). To “grant” such a patent license to a |
512 |
party means to make such an agreement or commitment not to enforce a |
513 |
patent against the party.</p>
|
514 |
|
515 |
<p>If you convey a covered work, knowingly relying on a patent license,
|
516 |
and the Corresponding Source of the work is not available for anyone |
517 |
to copy, free of charge and under the terms of this License, through a |
518 |
publicly available network server or other readily accessible means, |
519 |
then you must either (1) cause the Corresponding Source to be so |
520 |
available, or (2) arrange to deprive yourself of the benefit of the |
521 |
patent license for this particular work, or (3) arrange, in a manner |
522 |
consistent with the requirements of this License, to extend the patent |
523 |
license to downstream recipients. “Knowingly relying” means you have |
524 |
actual knowledge that, but for the patent license, your conveying the |
525 |
covered work in a country, or your recipient's use of the covered work |
526 |
in a country, would infringe one or more identifiable patents in that |
527 |
country that you have reason to believe are valid.</p>
|
528 |
|
529 |
<p>If, pursuant to or in connection with a single transaction or
|
530 |
arrangement, you convey, or propagate by procuring conveyance of, a |
531 |
covered work, and grant a patent license to some of the parties |
532 |
receiving the covered work authorizing them to use, propagate, modify |
533 |
or convey a specific copy of the covered work, then the patent license |
534 |
you grant is automatically extended to all recipients of the covered |
535 |
work and works based on it.</p>
|
536 |
|
537 |
<p>A patent license is “discriminatory” if it does not include within
|
538 |
the scope of its coverage, prohibits the exercise of, or is |
539 |
conditioned on the non-exercise of one or more of the rights that are |
540 |
specifically granted under this License. You may not convey a covered |
541 |
work if you are a party to an arrangement with a third party that is |
542 |
in the business of distributing software, under which you make payment |
543 |
to the third party based on the extent of your activity of conveying |
544 |
the work, and under which the third party grants, to any of the |
545 |
parties who would receive the covered work from you, a discriminatory |
546 |
patent license (a) in connection with copies of the covered work |
547 |
conveyed by you (or copies made from those copies), or (b) primarily |
548 |
for and in connection with specific products or compilations that |
549 |
contain the covered work, unless you entered into that arrangement, |
550 |
or that patent license was granted, prior to 28 March 2007.</p>
|
551 |
|
552 |
<p>Nothing in this License shall be construed as excluding or limiting
|
553 |
any implied license or other defenses to infringement that may |
554 |
otherwise be available to you under applicable patent law.</p>
|
555 |
|
556 |
<h4><a name="section12"></a>12. No Surrender of Others' Freedom.</h4> |
557 |
|
558 |
<p>If conditions are imposed on you (whether by court order, agreement or
|
559 |
otherwise) that contradict the conditions of this License, they do not |
560 |
excuse you from the conditions of this License. If you cannot convey a |
561 |
covered work so as to satisfy simultaneously your obligations under this |
562 |
License and any other pertinent obligations, then as a consequence you may |
563 |
not convey it at all. For example, if you agree to terms that obligate you |
564 |
to collect a royalty for further conveying from those to whom you convey |
565 |
the Program, the only way you could satisfy both those terms and this |
566 |
License would be to refrain entirely from conveying the Program.</p>
|
567 |
|
568 |
<h4><a name="section13"></a>13. Use with the GNU Affero General Public License.</h4> |
569 |
|
570 |
<p>Notwithstanding any other provision of this License, you have
|
571 |
permission to link or combine any covered work with a work licensed |
572 |
under version 3 of the GNU Affero General Public License into a single |
573 |
combined work, and to convey the resulting work. The terms of this |
574 |
License will continue to apply to the part which is the covered work, |
575 |
but the special requirements of the GNU Affero General Public License, |
576 |
section 13, concerning interaction through a network will apply to the |
577 |
combination as such.</p>
|
578 |
|
579 |
<h4><a name="section14"></a>14. Revised Versions of this License.</h4> |
580 |
|
581 |
<p>The Free Software Foundation may publish revised and/or new versions of
|
582 |
the GNU General Public License from time to time. Such new versions will |
583 |
be similar in spirit to the present version, but may differ in detail to |
584 |
address new problems or concerns.</p>
|
585 |
|
586 |
<p>Each version is given a distinguishing version number. If the
|
587 |
Program specifies that a certain numbered version of the GNU General |
588 |
Public License “or any later version” applies to it, you have the |
589 |
option of following the terms and conditions either of that numbered |
590 |
version or of any later version published by the Free Software |
591 |
Foundation. If the Program does not specify a version number of the |
592 |
GNU General Public License, you may choose any version ever published |
593 |
by the Free Software Foundation.</p>
|
594 |
|
595 |
<p>If the Program specifies that a proxy can decide which future
|
596 |
versions of the GNU General Public License can be used, that proxy's |
597 |
public statement of acceptance of a version permanently authorizes you |
598 |
to choose that version for the Program.</p>
|
599 |
|
600 |
<p>Later license versions may give you additional or different
|
601 |
permissions. However, no additional obligations are imposed on any |
602 |
author or copyright holder as a result of your choosing to follow a |
603 |
later version.</p>
|
604 |
|
605 |
<h4><a name="section15"></a>15. Disclaimer of Warranty.</h4> |
606 |
|
607 |
<p>THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
|
608 |
APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT |
609 |
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM “AS IS” WITHOUT WARRANTY |
610 |
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, |
611 |
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR |
612 |
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM |
613 |
IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF |
614 |
ALL NECESSARY SERVICING, REPAIR OR CORRECTION.</p>
|
615 |
|
616 |
<h4><a name="section16"></a>16. Limitation of Liability.</h4> |
617 |
|
618 |
<p>IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
|
619 |
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS |
620 |
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY |
621 |
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE |
622 |
USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF |
623 |
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD |
624 |
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), |
625 |
EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF |
626 |
SUCH DAMAGES.</p>
|
627 |
|
628 |
<h4><a name="section17"></a>17. Interpretation of Sections 15 and 16.</h4> |
629 |
|
630 |
<p>If the disclaimer of warranty and limitation of liability provided
|
631 |
above cannot be given local legal effect according to their terms, |
632 |
reviewing courts shall apply local law that most closely approximates |
633 |
an absolute waiver of all civil liability in connection with the |
634 |
Program, unless a warranty or assumption of liability accompanies a |
635 |
copy of the Program in return for a fee.</p>

<p>END OF TERMS AND CONDITIONS</p> |

|
639 |
<h3><a name="howto"></a>How to Apply These Terms to Your New Programs</h3> |
640 |
|
641 |
<p>If you develop a new program, and you want it to be of the greatest
|
642 |
possible use to the public, the best way to achieve this is to make it |
643 |
free software which everyone can redistribute and change under these terms.</p>
|
644 |
|
645 |
<p>To do so, attach the following notices to the program. It is safest
|
646 |
to attach them to the start of each source file to most effectively |
647 |
state the exclusion of warranty; and each file should have at least |
648 |
the “copyright” line and a pointer to where the full notice is found.</p>
|
649 |
|
650 |
<pre> <one line to give the program's name and a brief idea of what it does.> |

This program is distributed in the hope that it will be useful, |
659 |

You should have received a copy of the GNU General Public License |
664 |

</pre>
|
666 |
|
667 |
<p>Also add information on how to contact you by electronic and paper mail.</p> |
668 |
|
669 |
<p>If the program does terminal interaction, make it output a short
|
670 |
notice like this when it starts in an interactive mode:</p>
|
671 |
|
672 |
<pre> <program> Copyright (C) <year> <name of author> |

675 |
under certain conditions; type `show c' for details. |
676 |
</pre>
|
677 |
|
678 |
<p>The hypothetical commands `show w' and `show c' should show the appropriate
|
679 |
parts of the General Public License. Of course, your program's commands |
680 |
might be different; for a GUI interface, you would use an “about box”.</p>
|
681 |
|
682 |
<p>You should also get your employer (if you work as a programmer) or school,
|
683 |
if any, to sign a “copyright disclaimer” for the program, if necessary. |

<p>The GNU General Public License does not permit incorporating your program
