13
 Everyone is permitted to copy and distribute verbatim copies
14
 of this license document, but changing it is not allowed.</p>
15
16
<p>This version of the GNU Lesser General Public License incorporates
17
the terms and conditions of version 3 of the GNU General Public
18
License, supplemented by the additional permissions listed below.</p>
19
20
<h4><a name="section0"></a>0. Additional Definitions.</h4>
21
22
<p>As used herein, “this License” refers to version 3 of the GNU Lesser
23
General Public License, and the “GNU GPL” refers to version 3 of the GNU
24
General Public License.</p>
25
26
<p>“The Library” refers to a covered work governed by this License,
27
other than an Application or a Combined Work as defined below.</p>
28
29
<p>An “Application” is any work that makes use of an interface provided
30
by the Library, but which is not otherwise based on the Library.
31
Defining a subclass of a class defined by the Library is deemed a mode
32
of using an interface provided by the Library.</p>
33
34
<p>A “Combined Work” is a work produced by combining or linking an
35
Application with the Library.  The particular version of the Library
36
with which the Combined Work was made is also called the “Linked
37
Version”.</p>
38
39
<p>The “Minimal Corresponding Source” for a Combined Work means the
40
Corresponding Source for the Combined Work, excluding any source code
41
for portions of the Combined Work that, considered in isolation, are
42
based on the Application, and not on the Linked Version.</p>
43
44
<p>The “Corresponding Application Code” for a Combined Work means the
45
object code and/or source code for the Application, including any data
46
and utility programs needed for reproducing the Combined Work from the
47
Application, but excluding the System Libraries of the Combined Work.</p>
48
49
<h4><a name="section1"></a>1. Exception to Section 3 of the GNU GPL.</h4>
50
51
<p>You may convey a covered work under sections 3 and 4 of this License
52
without being bound by section 3 of the GNU GPL.</p>
53
54
<h4><a name="section2"></a>2. Conveying Modified Versions.</h4>
55
56
<p>If you modify a copy of the Library, and, in your modifications, a
57
facility refers to a function or data to be supplied by an Application
58
that uses the facility (other than as an argument passed when the
59
facility is invoked), then you may convey a copy of the modified
60
version:</p>
61
62
<ul>
63
<li>a) under this License, provided that you make a good faith effort to
64
   ensure that, in the event an Application does not supply the
65
   function or data, the facility still operates, and performs
66
   whatever part of its purpose remains meaningful, or</li>
67
68
<li>b) under the GNU GPL, with none of the additional permissions of
69
   this License applicable to that copy.</li>
70
</ul>
71
72
<h4><a name="section3"></a>3. Object Code Incorporating Material from Library Header Files.</h4>
73
74
<p>The object code form of an Application may incorporate material from
75
a header file that is part of the Library.  You may convey such object
76
code under terms of your choice, provided that, if the incorporated
77
material is not limited to numerical parameters, data structure
78
layouts and accessors, or small macros, inline functions and templates
79
(ten or fewer lines in length), you do both of the following:</p>
80
81
<ul>
82
<li>a) Give prominent notice with each copy of the object code that the
83
   Library is used in it and that the Library and its use are
84
   covered by this License.</li>
85
86
<li>b) Accompany the object code with a copy of the GNU GPL and this license
87
   document.</li>
88
</ul>
89
90
<h4><a name="section4"></a>4. Combined Works.</h4>
91
92
<p>You may convey a Combined Work under terms of your choice that,
93
taken together, effectively do not restrict modification of the
94
portions of the Library contained in the Combined Work and reverse
95
engineering for debugging such modifications, if you also do each of
96
the following:</p>
97
98
<ul>
99
<li>a) Give prominent notice with each copy of the Combined Work that
100
   the Library is used in it and that the Library and its use are
101
   covered by this License.</li>
102
103
<li>b) Accompany the Combined Work with a copy of the GNU GPL and this license
104
   document.</li>
105
106
<li>c) For a Combined Work that displays copyright notices during
107
   execution, include the copyright notice for the Library among
108
   these notices, as well as a reference directing the user to the
109
   copies of the GNU GPL and this license document.</li>
110
111
<li>d) Do one of the following:
112
113
<ul>
114
<li>0) Convey the Minimal Corresponding Source under the terms of this
115
       License, and the Corresponding Application Code in a form
116
       suitable for, and under terms that permit, the user to
117
       recombine or relink the Application with a modified version of
118
       the Linked Version to produce a modified Combined Work, in the
119
       manner specified by section 6 of the GNU GPL for conveying
120
       Corresponding Source.</li>
121
122
<li>1) Use a suitable shared library mechanism for linking with the
123
       Library.  A suitable mechanism is one that (a) uses at run time
124
       a copy of the Library already present on the user's computer
125
       system, and (b) will operate properly with a modified version
126
       of the Library that is interface-compatible with the Linked
127
       Version.</li>
128
</ul></li>
129
130
<li>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.)</li>
141
</ul>
142
143
<h4><a name="section5"></a>5. Combined Libraries.</h4>
144
145
<p>You may place library facilities that are a work based on the
146
Library side by side in a single library together with other library
147
facilities that are not Applications and are not covered by this
148
License, and convey such a combined library under terms of your
149
choice, if you do both of the following:</p>
150
151
<ul>
152
<li>a) Accompany the combined library with a copy of the same work based
153
   on the Library, uncombined with any other library facilities,
154
   conveyed under the terms of this License.</li>
155
156
<li>b) Give prominent notice with the combined library that part of it
157
   is a work based on the Library, and explaining where to find the
158
   accompanying uncombined form of the same work.</li>
159
</ul>
160
161
<h4><a name="section6"></a>6. Revised Versions of the GNU Lesser General Public License.</h4>
162
163
<p>The Free Software Foundation may publish revised and/or new versions
164
of the GNU Lesser General Public License from time to time. Such new
165
versions will be similar in spirit to the present version, but may
166
differ in detail to address new problems or concerns.</p>
167
168
<p>Each version is given a distinguishing version number. If the
169
Library as you received it specifies that a certain numbered version
170
of the GNU Lesser General Public License “or any later version”
171
applies to it, you have the option of following the terms and
172
conditions either of that published version or of any later version
173
published by the Free Software Foundation. If the Library as you
174
received it does not specify a version number of the GNU Lesser
175
General Public License, you may choose any version of the GNU Lesser
176
General Public License ever published by the Free Software Foundation.</p>
177
178
<p>If the Library as you received it specifies that a proxy can decide
179
whether future versions of the GNU Lesser General Public License shall
180
apply, that proxy's public statement of acceptance of any version is
181
permanent authorization for you to choose that version for the
182
Library.</p>

<p>Copyright © 2007 Free Software Foundation, Inc.

 &lt;<a href="http://fsf.org/">http://fsf.org/</a>&gt;</p><p>
191
 Everyone is permitted to copy and distribute verbatim copies
192
 of this license document, but changing it is not allowed.</p>
193
194
<h3><a name="preamble"></a>Preamble</h3>
195
196
<p>The GNU General Public License is a free, copyleft license for
197
software and other kinds of works.</p>
198
199
<p>The licenses for most software and other practical works are designed
200
to take away your freedom to share and change the works.  By contrast,
201
the GNU General Public License is intended to guarantee your freedom to
202
share and change all versions of a program--to make sure it remains free
203
software for all its users.  We, the Free Software Foundation, use the
204
GNU General Public License for most of our software; it applies also to
205
any other work released this way by its authors.  You can apply it to
206
your programs, too.</p>
207
208
<p>When we speak of free software, we are referring to freedom, not
209
price.  Our General Public Licenses are designed to make sure that you
210
have the freedom to distribute copies of free software (and charge for
211
them if you wish), that you receive source code or can get it if you
212
want it, that you can change the software or use pieces of it in new
213
free programs, and that you know you can do these things.</p>
214
215
<p>To protect your rights, we need to prevent others from denying you
216
these rights or asking you to surrender the rights.  Therefore, you have
217
certain responsibilities if you distribute copies of the software, or if
218
you modify it: responsibilities to respect the freedom of others.</p>
219
220
<p>For example, if you distribute copies of such a program, whether
221
gratis or for a fee, you must pass on to the recipients the same
222
freedoms that you received.  You must make sure that they, too, receive
223
or can get the source code.  And you must show them these terms so they
224
know their rights.</p>
225
226
<p>Developers that use the GNU GPL protect your rights with two steps:
227
(1) assert copyright on the software, and (2) offer you this License
228
giving you legal permission to copy, distribute and/or modify it.</p>
229
230
<p>For the developers' and authors' protection, the GPL clearly explains
231
that there is no warranty for this free software.  For both users' and
232
authors' sake, the GPL requires that modified versions be marked as
233
changed, so that their problems will not be attributed erroneously to
234
authors of previous versions.</p>
235
236
<p>Some devices are designed to deny users access to install or run
237
modified versions of the software inside them, although the manufacturer
238
can do so.  This is fundamentally incompatible with the aim of
239
protecting users' freedom to change the software.  The systematic
240
pattern of such abuse occurs in the area of products for individuals to
241
use, which is precisely where it is most unacceptable.  Therefore, we
242
have designed this version of the GPL to prohibit the practice for those
243
products.  If such problems arise substantially in other domains, we
244
stand ready to extend this provision to those domains in future versions
245
of the GPL, as needed to protect the freedom of users.</p>
246
247
<p>Finally, every program is threatened constantly by software patents.
248
States should not allow patents to restrict development and use of
249
software on general-purpose computers, but in those that do, we wish to
250
avoid the special danger that patents applied to a free program could
251
make it effectively proprietary.  To prevent this, the GPL assures that
252
patents cannot be used to render the program non-free.</p>
253
254
<p>The precise terms and conditions for copying, distribution and
255
modification follow.</p>
256
257
<h3><a name="terms"></a>TERMS AND CONDITIONS</h3>
258
259
<h4><a name="section0"></a>0. Definitions.</h4>
260
261
<p>“This License” refers to version 3 of the GNU General Public License.</p>
262
263
<p>“Copyright” also means copyright-like laws that apply to other kinds of
264
works, such as semiconductor masks.</p>
265
 
266
<p>“The Program” refers to any copyrightable work licensed under this
267
License.  Each licensee is addressed as “you”.  “Licensees” and
268
“recipients” may be individuals or organizations.</p>
269
270
<p>To “modify” a work means to copy from or adapt all or part of the work
271
in a fashion requiring copyright permission, other than the making of an
272
exact copy.  The resulting work is called a “modified version” of the
273
earlier work or a work “based on” the earlier work.</p>
274
275
<p>A “covered work” means either the unmodified Program or a work based
276
on the Program.</p>
277
278
<p>To “propagate” a work means to do anything with it that, without
279
permission, would make you directly or secondarily liable for
280
infringement under applicable copyright law, except executing it on a
281
computer or modifying a private copy.  Propagation includes copying,
282
distribution (with or without modification), making available to the
283
public, and in some countries other activities as well.</p>
284
285
<p>To “convey” a work means any kind of propagation that enables other
286
parties to make or receive copies.  Mere interaction with a user through
287
a computer network, with no transfer of a copy, is not conveying.</p>
288
289
<p>An interactive user interface displays “Appropriate Legal Notices”
290
to the extent that it includes a convenient and prominently visible
291
feature that (1) displays an appropriate copyright notice, and (2)
292
tells the user that there is no warranty for the work (except to the
293
extent that warranties are provided), that licensees may convey the
294
work under this License, and how to view a copy of this License.  If
295
the interface presents a list of user commands or options, such as a
296
menu, a prominent item in the list meets this criterion.</p>
297
298
<h4><a name="section1"></a>1. Source Code.</h4>
299
300
<p>The “source code” for a work means the preferred form of the work
301
for making modifications to it.  “Object code” means any non-source
302
form of a work.</p>
303
304
<p>A “Standard Interface” means an interface that either is an official
305
standard defined by a recognized standards body, or, in the case of
306
interfaces specified for a particular programming language, one that
307
is widely used among developers working in that language.</p>
308
309
<p>The “System Libraries” of an executable work include anything, other
310
than the work as a whole, that (a) is included in the normal form of
311
packaging a Major Component, but which is not part of that Major
312
Component, and (b) serves only to enable use of the work with that
313
Major Component, or to implement a Standard Interface for which an
314
implementation is available to the public in source code form.  A
315
“Major Component”, in this context, means a major essential component
316
(kernel, window system, and so on) of the specific operating system
317
(if any) on which the executable work runs, or a compiler used to
318
produce the work, or an object code interpreter used to run it.</p>
319
320
<p>The “Corresponding Source” for a work in object code form means all
321
the source code needed to generate, install, and (for an executable
322
work) run the object code and to modify the work, including scripts to
323
control those activities.  However, it does not include the work's
324
System Libraries, or general-purpose tools or generally available free
325
programs which are used unmodified in performing those activities but
326
which are not part of the work.  For example, Corresponding Source
327
includes interface definition files associated with source files for
328
the work, and the source code for shared libraries and dynamically
329
linked subprograms that the work is specifically designed to require,
330
such as by intimate data communication or control flow between those
331
subprograms and other parts of the work.</p>
332
333
<p>The Corresponding Source need not include anything that users
334
can regenerate automatically from other parts of the Corresponding
335
Source.</p>
336
337
<p>The Corresponding Source for a work in source code form is that
338
same work.</p>
339
340
<h4><a name="section2"></a>2. Basic Permissions.</h4>
341
342
<p>All rights granted under this License are granted for the term of
343
copyright on the Program, and are irrevocable provided the stated
344
conditions are met.  This License explicitly affirms your unlimited
345
permission to run the unmodified Program.  The output from running a
346
covered work is covered by this License only if the output, given its
347
content, constitutes a covered work.  This License acknowledges your
348
rights of fair use or other equivalent, as provided by copyright law.</p>
349
350
<p>You may make, run and propagate covered works that you do not
351
convey, without conditions so long as your license otherwise remains
352
in force.  You may convey covered works to others for the sole purpose
353
of having them make modifications exclusively for you, or provide you
354
with facilities for running those works, provided that you comply with
355
the terms of this License in conveying all material for which you do
356
not control copyright.  Those thus making or running the covered works
357
for you must do so exclusively on your behalf, under your direction
358
and control, on terms that prohibit them from making any copies of
359
your copyrighted material outside their relationship with you.</p>
360
361
<p>Conveying under any other circumstances is permitted solely under
362
the conditions stated below.  Sublicensing is not allowed; section 10
363
makes it unnecessary.</p>
364
365
<h4><a name="section3"></a>3. Protecting Users' Legal Rights From Anti-Circumvention Law.</h4>
366
367
<p>No covered work shall be deemed part of an effective technological
368
measure under any applicable law fulfilling obligations under article
369
11 of the WIPO copyright treaty adopted on 20 December 1996, or
370
similar laws prohibiting or restricting circumvention of such
371
measures.</p>
372
373
<p>When you convey a covered work, you waive any legal power to forbid
374
circumvention of technological measures to the extent such circumvention
375
is effected by exercising rights under this License with respect to
376
the covered work, and you disclaim any intention to limit operation or
377
modification of the work as a means of enforcing, against the work's
378
users, your or third parties' legal rights to forbid circumvention of
379
technological measures.</p>
380
381
<h4><a name="section4"></a>4. Conveying Verbatim Copies.</h4>
382
383
<p>You may convey verbatim copies of the Program's source code as you
384
receive it, in any medium, provided that you conspicuously and
385
appropriately publish on each copy an appropriate copyright notice;
386
keep intact all notices stating that this License and any
387
non-permissive terms added in accord with section 7 apply to the code;
388
keep intact all notices of the absence of any warranty; and give all
389
recipients a copy of this License along with the Program.</p>
390
391
<p>You may charge any price or no price for each copy that you convey,
392
and you may offer support or warranty protection for a fee.</p>
393
394
<h4><a name="section5"></a>5. Conveying Modified Source Versions.</h4>
395
396
<p>You may convey a work based on the Program, or the modifications to
397
produce it from the Program, in the form of source code under the
398
terms of section 4, provided that you also meet all of these conditions:</p>
399
400
<ul>
401
<li>a) The work must carry prominent notices stating that you modified
402
    it, and giving a relevant date.</li>
403
404
<li>b) The work must carry prominent notices stating that it is
405
    released under this License and any conditions added under section
406
    7.  This requirement modifies the requirement in section 4 to
407
    “keep intact all notices”.</li>
408
409
<li>c) You must license the entire work, as a whole, under this
410
    License to anyone who comes into possession of a copy.  This
411
    License will therefore apply, along with any applicable section 7
412
    additional terms, to the whole of the work, and all its parts,
413
    regardless of how they are packaged.  This License gives no
414
    permission to license the work in any other way, but it does not
415
    invalidate such permission if you have separately received it.</li>
416
417
<li>d) If the work has interactive user interfaces, each must display
418
    Appropriate Legal Notices; however, if the Program has interactive
419
    interfaces that do not display Appropriate Legal Notices, your
420
    work need not make them do so.</li>
421
</ul>
422
423
<p>A compilation of a covered work with other separate and independent
424
works, which are not by their nature extensions of the covered work,
425
and which are not combined with it such as to form a larger program,
426
in or on a volume of a storage or distribution medium, is called an
427
“aggregate” if the compilation and its resulting copyright are not
428
used to limit the access or legal rights of the compilation's users
429
beyond what the individual works permit.  Inclusion of a covered work
430
in an aggregate does not cause this License to apply to the other
431
parts of the aggregate.</p>
432
433
<h4><a name="section6"></a>6. Conveying Non-Source Forms.</h4>
434
435
<p>You may convey a covered work in object code form under the terms
436
of sections 4 and 5, provided that you also convey the
437
machine-readable Corresponding Source under the terms of this License,
438
in one of these ways:</p>
439
440
<ul>
441
<li>a) Convey the object code in, or embodied in, a physical product
442
    (including a physical distribution medium), accompanied by the
443
    Corresponding Source fixed on a durable physical medium
444
    customarily used for software interchange.</li>
445
446
<li>b) Convey the object code in, or embodied in, a physical product
447
    (including a physical distribution medium), accompanied by a
448
    written offer, valid for at least three years and valid for as
449
    long as you offer spare parts or customer support for that product
450
    model, to give anyone who possesses the object code either (1) a
451
    copy of the Corresponding Source for all the software in the
452
    product that is covered by this License, on a durable physical
453
    medium customarily used for software interchange, for a price no
454
    more than your reasonable cost of physically performing this
455
    conveying of source, or (2) access to copy the
456
    Corresponding Source from a network server at no charge.</li>
457
458
<li>c) Convey individual copies of the object code with a copy of the
459
    written offer to provide the Corresponding Source.  This
460
    alternative is allowed only occasionally and noncommercially, and
461
    only if you received the object code with such an offer, in accord
462
    with subsection 6b.</li>
463
464
<li>d) Convey the object code by offering access from a designated
465
    place (gratis or for a charge), and offer equivalent access to the
466
    Corresponding Source in the same way through the same place at no
467
    further charge.  You need not require recipients to copy the
468
    Corresponding Source along with the object code.  If the place to
469
    copy the object code is a network server, the Corresponding Source
470
    may be on a different server (operated by you or a third party)
471
    that supports equivalent copying facilities, provided you maintain
472
    clear directions next to the object code saying where to find the
473
    Corresponding Source.  Regardless of what server hosts the
474
    Corresponding Source, you remain obligated to ensure that it is
475
    available for as long as needed to satisfy these requirements.</li>
476
477
<li>e) Convey the object code using peer-to-peer transmission, provided
478
    you inform other peers where the object code and Corresponding
479
    Source of the work are being offered to the general public at no
480
    charge under subsection 6d.</li>
481
</ul>
482
483
<p>A separable portion of the object code, whose source code is excluded
484
from the Corresponding Source as a System Library, need not be
485
included in conveying the object code work.</p>
486
487
<p>A “User Product” is either (1) a “consumer product”, which means any
488
tangible personal property which is normally used for personal, family,
489
or household purposes, or (2) anything designed or sold for incorporation
490
into a dwelling.  In determining whether a product is a consumer product,
491
doubtful cases shall be resolved in favor of coverage.  For a particular
492
product received by a particular user, “normally used” refers to a
493
typical or common use of that class of product, regardless of the status
494
of the particular user or of the way in which the particular user
495
actually uses, or expects or is expected to use, the product.  A product
496
is a consumer product regardless of whether the product has substantial
497
commercial, industrial or non-consumer uses, unless such uses represent
498
the only significant mode of use of the product.</p>
499
500
<p>“Installation Information” for a User Product means any methods,
501
procedures, authorization keys, or other information required to install
502
and execute modified versions of a covered work in that User Product from
503
a modified version of its Corresponding Source.  The information must
504
suffice to ensure that the continued functioning of the modified object
505
code is in no case prevented or interfered with solely because
506
modification has been made.</p>
507
508
<p>If you convey an object code work under this section in, or with, or
509
specifically for use in, a User Product, and the conveying occurs as
510
part of a transaction in which the right of possession and use of the
511
User Product is transferred to the recipient in perpetuity or for a
512
fixed term (regardless of how the transaction is characterized), the
513
Corresponding Source conveyed under this section must be accompanied
514
by the Installation Information.  But this requirement does not apply
515
if neither you nor any third party retains the ability to install
516
modified object code on the User Product (for example, the work has
517
been installed in ROM).</p>
518
519
<p>The requirement to provide Installation Information does not include a
520
requirement to continue to provide support service, warranty, or updates
521
for a work that has been modified or installed by the recipient, or for
522
the User Product in which it has been modified or installed.  Access to a
523
network may be denied when the modification itself materially and
524
adversely affects the operation of the network or violates the rules and
525
protocols for communication across the network.</p>
526
527
<p>Corresponding Source conveyed, and Installation Information provided,
528
in accord with this section must be in a format that is publicly
529
documented (and with an implementation available to the public in
530
source code form), and must require no special password or key for
531
unpacking, reading or copying.</p>
532
533
<h4><a name="section7"></a>7. Additional Terms.</h4>
534
535
<p>“Additional permissions” are terms that supplement the terms of this
536
License by making exceptions from one or more of its conditions.
537
Additional permissions that are applicable to the entire Program shall
538
be treated as though they were included in this License, to the extent
539
that they are valid under applicable law.  If additional permissions
540
apply only to part of the Program, that part may be used separately
541
under those permissions, but the entire Program remains governed by
542
this License without regard to the additional permissions.</p>
543
544
<p>When you convey a copy of a covered work, you may at your option
545
remove any additional permissions from that copy, or from any part of
546
it.  (Additional permissions may be written to require their own
547
removal in certain cases when you modify the work.)  You may place
548
additional permissions on material, added by you to a covered work,
549
for which you have or can give appropriate copyright permission.</p>
550
551
<p>Notwithstanding any other provision of this License, for material you
552
add to a covered work, you may (if authorized by the copyright holders of
553
that material) supplement the terms of this License with terms:</p>
554
555
<ul>
556
<li>a) Disclaiming warranty or limiting liability differently from the
557
    terms of sections 15 and 16 of this License; or</li>
558
559
<li>b) Requiring preservation of specified reasonable legal notices or
560
    author attributions in that material or in the Appropriate Legal
561
    Notices displayed by works containing it; or</li>
562
563
<li>c) Prohibiting misrepresentation of the origin of that material, or
564
    requiring that modified versions of such material be marked in
565
    reasonable ways as different from the original version; or</li>
566
567
<li>d) Limiting the use for publicity purposes of names of licensors or
568
    authors of the material; or</li>
569
570
<li>e) Declining to grant rights under trademark law for use of some
571
    trade names, trademarks, or service marks; or</li>
572
573
<li>f) Requiring indemnification of licensors and authors of that
574
    material by anyone who conveys the material (or modified versions of
575
    it) with contractual assumptions of liability to the recipient, for
576
    any liability that these contractual assumptions directly impose on
577
    those licensors and authors.</li>
578
</ul>
579
580
<p>All other non-permissive additional terms are considered “further
581
restrictions” within the meaning of section 10.  If the Program as you
582
received it, or any part of it, contains a notice stating that it is
583
governed by this License along with a term that is a further
584
restriction, you may remove that term.  If a license document contains
585
a further restriction but permits relicensing or conveying under this
586
License, you may add to a covered work material governed by the terms
587
of that license document, provided that the further restriction does
588
not survive such relicensing or conveying.</p>
589
590
<p>If you add terms to a covered work in accord with this section, you
591
must place, in the relevant source files, a statement of the
592
additional terms that apply to those files, or a notice indicating
593
where to find the applicable terms.</p>
594
595
<p>Additional terms, permissive or non-permissive, may be stated in the
596
form of a separately written license, or stated as exceptions;
597
the above requirements apply either way.</p>
598
599
<h4><a name="section8"></a>8. Termination.</h4>
600
601
<p>You may not propagate or modify a covered work except as expressly
602
provided under this License.  Any attempt otherwise to propagate or
603
modify it is void, and will automatically terminate your rights under
604
this License (including any patent licenses granted under the third
605
paragraph of section 11).</p>
606
607
<p>However, if you cease all violation of this License, then your
608
license from a particular copyright holder is reinstated (a)
609
provisionally, unless and until the copyright holder explicitly and
610
finally terminates your license, and (b) permanently, if the copyright
611
holder fails to notify you of the violation by some reasonable means
612
prior to 60 days after the cessation.</p>
613
614
<p>Moreover, your license from a particular copyright holder is
615
reinstated permanently if the copyright holder notifies you of the
616
violation by some reasonable means, this is the first time you have
617
received notice of violation of this License (for any work) from that
618
copyright holder, and you cure the violation prior to 30 days after
619
your receipt of the notice.</p>
620
621
<p>Termination of your rights under this section does not terminate the
622
licenses of parties who have received copies or rights from you under
623
this License.  If your rights have been terminated and not permanently
624
reinstated, you do not qualify to receive new licenses for the same
625
material under section 10.</p>
626
627
<h4><a name="section9"></a>9. Acceptance Not Required for Having Copies.</h4>
628
629
<p>You are not required to accept this License in order to receive or
630
run a copy of the Program.  Ancillary propagation of a covered work
631
occurring solely as a consequence of using peer-to-peer transmission
632
to receive a copy likewise does not require acceptance.  However,
633
nothing other than this License grants you permission to propagate or
634
modify any covered work.  These actions infringe copyright if you do
635
not accept this License.  Therefore, by modifying or propagating a
636
covered work, you indicate your acceptance of this License to do so.</p>
637
638
<h4><a name="section10"></a>10. Automatic Licensing of Downstream Recipients.</h4>
639
640
<p>Each time you convey a covered work, the recipient automatically
641
receives a license from the original licensors, to run, modify and
642
propagate that work, subject to this License.  You are not responsible
643
for enforcing compliance by third parties with this License.</p>
644
645
<p>An “entity transaction” is a transaction transferring control of an
646
organization, or substantially all assets of one, or subdividing an
647
organization, or merging organizations.  If propagation of a covered
648
work results from an entity transaction, each party to that
649
transaction who receives a copy of the work also receives whatever
650
licenses to the work the party's predecessor in interest had or could
651
give under the previous paragraph, plus a right to possession of the
652
Corresponding Source of the work from the predecessor in interest, if
653
the predecessor has it or can get it with reasonable efforts.</p>
654
655
<p>You may not impose any further restrictions on the exercise of the
656
rights granted or affirmed under this License.  For example, you may
657
not impose a license fee, royalty, or other charge for exercise of
658
rights granted under this License, and you may not initiate litigation
659
(including a cross-claim or counterclaim in a lawsuit) alleging that
660
any patent claim is infringed by making, using, selling, offering for
661
sale, or importing the Program or any portion of it.</p>
662
663
<h4><a name="section11"></a>11. Patents.</h4>
664
665
<p>A “contributor” is a copyright holder who authorizes use under this
666
License of the Program or a work on which the Program is based.  The
667
work thus licensed is called the contributor's “contributor version”.</p>
668
669
<p>A contributor's “essential patent claims” are all patent claims
670
owned or controlled by the contributor, whether already acquired or
671
hereafter acquired, that would be infringed by some manner, permitted
672
by this License, of making, using, or selling its contributor version,
673
but do not include claims that would be infringed only as a
674
consequence of further modification of the contributor version.  For
675
purposes of this definition, “control” includes the right to grant
676
patent sublicenses in a manner consistent with the requirements of
677
this License.</p>
678
679
<p>Each contributor grants you a non-exclusive, worldwide, royalty-free
680
patent license under the contributor's essential patent claims, to
681
make, use, sell, offer for sale, import and otherwise run, modify and
682
propagate the contents of its contributor version.</p>
683
684
<p>In the following three paragraphs, a “patent license” is any express
685
agreement or commitment, however denominated, not to enforce a patent
686
(such as an express permission to practice a patent or covenant not to
687
sue for patent infringement).  To “grant” such a patent license to a
688
party means to make such an agreement or commitment not to enforce a
689
patent against the party.</p>
690
691
<p>If you convey a covered work, knowingly relying on a patent license,
692
and the Corresponding Source of the work is not available for anyone
693
to copy, free of charge and under the terms of this License, through a
694
publicly available network server or other readily accessible means,
695
then you must either (1) cause the Corresponding Source to be so
696
available, or (2) arrange to deprive yourself of the benefit of the
697
patent license for this particular work, or (3) arrange, in a manner
698
consistent with the requirements of this License, to extend the patent
699
license to downstream recipients.  “Knowingly relying” means you have
700
actual knowledge that, but for the patent license, your conveying the
701
covered work in a country, or your recipient's use of the covered work
702
in a country, would infringe one or more identifiable patents in that
703
country that you have reason to believe are valid.</p>
704
  
705
<p>If, pursuant to or in connection with a single transaction or
706
arrangement, you convey, or propagate by procuring conveyance of, a
707
covered work, and grant a patent license to some of the parties
708
receiving the covered work authorizing them to use, propagate, modify
709
or convey a specific copy of the covered work, then the patent license
710
you grant is automatically extended to all recipients of the covered
711
work and works based on it.</p>
712
713
<p>A patent license is “discriminatory” if it does not include within
714
the scope of its coverage, prohibits the exercise of, or is
715
conditioned on the non-exercise of one or more of the rights that are
716
specifically granted under this License.  You may not convey a covered
717
work if you are a party to an arrangement with a third party that is
718
in the business of distributing software, under which you make payment
719
to the third party based on the extent of your activity of conveying
720
the work, and under which the third party grants, to any of the
721
parties who would receive the covered work from you, a discriminatory
722
patent license (a) in connection with copies of the covered work
723
conveyed by you (or copies made from those copies), or (b) primarily
724
for and in connection with specific products or compilations that
725
contain the covered work, unless you entered into that arrangement,
726
or that patent license was granted, prior to 28 March 2007.</p>
727
728
<p>Nothing in this License shall be construed as excluding or limiting
729
any implied license or other defenses to infringement that may
730
otherwise be available to you under applicable patent law.</p>
731
732
<h4><a name="section12"></a>12. No Surrender of Others' Freedom.</h4>
733
734
<p>If conditions are imposed on you (whether by court order, agreement or
735
otherwise) that contradict the conditions of this License, they do not
736
excuse you from the conditions of this License.  If you cannot convey a
737
covered work so as to satisfy simultaneously your obligations under this
738
License and any other pertinent obligations, then as a consequence you may
739
not convey it at all.  For example, if you agree to terms that obligate you
740
to collect a royalty for further conveying from those to whom you convey
741
the Program, the only way you could satisfy both those terms and this
742
License would be to refrain entirely from conveying the Program.</p>
743
744
<h4><a name="section13"></a>13. Use with the GNU Affero General Public License.</h4>
745
746
<p>Notwithstanding any other provision of this License, you have
747
permission to link or combine any covered work with a work licensed
748
under version 3 of the GNU Affero General Public License into a single
749
combined work, and to convey the resulting work.  The terms of this
750
License will continue to apply to the part which is the covered work,
751
but the special requirements of the GNU Affero General Public License,
752
section 13, concerning interaction through a network will apply to the
753
combination as such.</p>
754
755
<h4><a name="section14"></a>14. Revised Versions of this License.</h4>
756
757
<p>The Free Software Foundation may publish revised and/or new versions of
758
the GNU General Public License from time to time.  Such new versions will
759
be similar in spirit to the present version, but may differ in detail to
760
address new problems or concerns.</p>
761
762
<p>Each version is given a distinguishing version number.  If the
763
Program specifies that a certain numbered version of the GNU General
764
Public License “or any later version” applies to it, you have the
765
option of following the terms and conditions either of that numbered
766
version or of any later version published by the Free Software
767
Foundation.  If the Program does not specify a version number of the
768
GNU General Public License, you may choose any version ever published
769
by the Free Software Foundation.</p>
770
771
<p>If the Program specifies that a proxy can decide which future
772
versions of the GNU General Public License can be used, that proxy's
773
public statement of acceptance of a version permanently authorizes you
774
to choose that version for the Program.</p>
775
776
<p>Later license versions may give you additional or different
777
permissions.  However, no additional obligations are imposed on any
778
author or copyright holder as a result of your choosing to follow a
779
later version.</p>
780
781
<h4><a name="section15"></a>15. Disclaimer of Warranty.</h4>
782
783
<p>THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
784
APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
785
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM “AS IS” WITHOUT WARRANTY
786
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
787
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
788
PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
789
IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
790
ALL NECESSARY SERVICING, REPAIR OR CORRECTION.</p>
791
792
<h4><a name="section16"></a>16. Limitation of Liability.</h4>
793
794
<p>IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
795
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
796
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
797
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
798
USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
799
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
800
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
801
EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
802
SUCH DAMAGES.</p>
803
804
<h4><a name="section17"></a>17. Interpretation of Sections 15 and 16.</h4>
805
806
<p>If the disclaimer of warranty and limitation of liability provided
807
above cannot be given local legal effect according to their terms,
808
reviewing courts shall apply local law that most closely approximates
809
an absolute waiver of all civil liability in connection with the
810
Program, unless a warranty or assumption of liability accompanies a
811
copy of the Program in return for a fee.</p>
812
813
<p>END OF TERMS AND CONDITIONS</p>
814
815
<h3><a name="howto"></a>How to Apply These Terms to Your New Programs</h3>
816
817
<p>If you develop a new program, and you want it to be of the greatest
818
possible use to the public, the best way to achieve this is to make it
819
free software which everyone can redistribute and change under these terms.</p>
820
821
<p>To do so, attach the following notices to the program.  It is safest
822
to attach them to the start of each source file to most effectively
823
state the exclusion of warranty; and each file should have at least
824
the “copyright” line and a pointer to where the full notice is found.</p>
825
826
<pre>    &lt;one line to give the program's name and a brief idea of what it does.&gt;
827
    Copyright (C) &lt;year&gt;  &lt;name of author&gt;

829
    This program is free software: you can redistribute it and/or modify
830
    it under the terms of the GNU General Public License as published by
831
    the Free Software Foundation, either version 3 of the License, or
832
    (at your option) any later version.
833
834
    This program is distributed in the hope that it will be useful,
835
    but WITHOUT ANY WARRANTY; without even the implied warranty of
836
    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
837
    GNU General Public License for more details.
838
839
    You should have received a copy of the GNU General Public License
840
    along with this program.  If not, see &lt;http://www.gnu.org/licenses/&gt;.
841
</pre>
842
843
<p>Also add information on how to contact you by electronic and paper mail.</p>
844
845
<p>If the program does terminal interaction, make it output a short
846
notice like this when it starts in an interactive mode:</p>
847
848
<pre>    &lt;program&gt;  Copyright (C) &lt;year&gt;  &lt;name of author&gt;
849
    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
850
    This is free software, and you are welcome to redistribute it
851
    under certain conditions; type `show c' for details.
852
</pre>
853
854
<p>The hypothetical commands `show w' and `show c' should show the appropriate
855
parts of the General Public License.  Of course, your program's commands
856
might be different; for a GUI interface, you would use an “about box”.</p>
857
858
<p>You should also get your employer (if you work as a programmer) or school,
859
if any, to sign a “copyright disclaimer” for the program, if necessary.
