 Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>

 Everyone is permitted to copy and distribute verbatim copies
6
 of this license document, but changing it is not allowed.

  This version of the GNU Lesser General Public License incorporates
10
the terms and conditions of version 3 of the GNU General Public
11
License, supplemented by the additional permissions listed below.
12

    
13
  0. Additional Definitions.
14

    
15
  As used herein, "this License" refers to version 3 of the GNU Lesser
16
General Public License, and the "GNU GPL" refers to version 3 of the GNU
17
General Public License.
18

    
19
  "The Library" refers to a covered work governed by this License,
20
other than an Application or a Combined Work as defined below.
21

    
22
  An "Application" is any work that makes use of an interface provided
23
by the Library, but which is not otherwise based on the Library.
24
Defining a subclass of a class defined by the Library is deemed a mode
25
of using an interface provided by the Library.
26

    
27
  A "Combined Work" is a work produced by combining or linking an
28
Application with the Library.  The particular version of the Library
29
with which the Combined Work was made is also called the "Linked
30
Version".
31

    
32
  The "Minimal Corresponding Source" for a Combined Work means the
33
Corresponding Source for the Combined Work, excluding any source code
34
for portions of the Combined Work that, considered in isolation, are
35
based on the Application, and not on the Linked Version.
36

    
37
  The "Corresponding Application Code" for a Combined Work means the
38
object code and/or source code for the Application, including any data
39
and utility programs needed for reproducing the Combined Work from the
40
Application, but excluding the System Libraries of the Combined Work.
41

    
42
  1. Exception to Section 3 of the GNU GPL.
43

    
44
  You may convey a covered work under sections 3 and 4 of this License
45
without being bound by section 3 of the GNU GPL.
46

    
47
  2. Conveying Modified Versions.
48

    
49
  If you modify a copy of the Library, and, in your modifications, a
50
facility refers to a function or data to be supplied by an Application
51
that uses the facility (other than as an argument passed when the
52
facility is invoked), then you may convey a copy of the modified
53
version:
54

    
55
   a) under this License, provided that you make a good faith effort to
56
   ensure that, in the event an Application does not supply the
57
   function or data, the facility still operates, and performs
58
   whatever part of its purpose remains meaningful, or
59

    
60
   b) under the GNU GPL, with none of the additional permissions of
61
   this License applicable to that copy.
62

    
63
  3. Object Code Incorporating Material from Library Header Files.
64

    
65
  The object code form of an Application may incorporate material from
66
a header file that is part of the Library.  You may convey such object
67
code under terms of your choice, provided that, if the incorporated
68
material is not limited to numerical parameters, data structure
69
layouts and accessors, or small macros, inline functions and templates
70
(ten or fewer lines in length), you do both of the following:
71

    
72
   a) Give prominent notice with each copy of the object code that the
73
   Library is used in it and that the Library and its use are
74
   covered by this License.
75

    
76
   b) Accompany the object code with a copy of the GNU GPL and this license
77
   document.
78

    
79
  4. Combined Works.
80

    
81
  You may convey a Combined Work under terms of your choice that,
82
taken together, effectively do not restrict modification of the
83
portions of the Library contained in the Combined Work and reverse
84
engineering for debugging such modifications, if you also do each of
85
the following:
86

    
87
   a) Give prominent notice with each copy of the Combined Work that
88
   the Library is used in it and that the Library and its use are
89
   covered by this License.
90

    
91
   b) Accompany the Combined Work with a copy of the GNU GPL and this license
92
   document.
93

    
94
   c) For a Combined Work that displays copyright notices during
95
   execution, include the copyright notice for the Library among
96
   these notices, as well as a reference directing the user to the
97
   copies of the GNU GPL and this license document.
98

    
99
   d) Do one of the following:
100

    
101
       0) Convey the Minimal Corresponding Source under the terms of this
102
       License, and the Corresponding Application Code in a form
103
       suitable for, and under terms that permit, the user to
104
       recombine or relink the Application with a modified version of
105
       the Linked Version to produce a modified Combined Work, in the
106
       manner specified by section 6 of the GNU GPL for conveying
107
       Corresponding Source.
108

    
109
       1) Use a suitable shared library mechanism for linking with the
110
       Library.  A suitable mechanism is one that (a) uses at run time
111
       a copy of the Library already present on the user's computer
112
       system, and (b) will operate properly with a modified version
113
       of the Library that is interface-compatible with the Linked
114
       Version.
115

    
116
   e) Provide Installation Information, but only if you would otherwise
117
   be required to provide such information under section 6 of the
118
   GNU GPL, and only to the extent that such information is
119
   necessary to install and execute a modified version of the
120
   Combined Work produced by recombining or relinking the
121
   Application with a modified version of the Linked Version. (If
122
   you use option 4d0, the Installation Information must accompany
123
   the Minimal Corresponding Source and Corresponding Application
124
   Code. If you use option 4d1, you must provide the Installation
125
   Information in the manner specified by section 6 of the GNU GPL
126
   for conveying Corresponding Source.)
127

    
128
  5. Combined Libraries.
129

    
130
  You may place library facilities that are a work based on the
131
Library side by side in a single library together with other library
132
facilities that are not Applications and are not covered by this
133
License, and convey such a combined library under terms of your
134
choice, if you do both of the following:
135

    
136
   a) Accompany the combined library with a copy of the same work based
137
   on the Library, uncombined with any other library facilities,
138
   conveyed under the terms of this License.
139

    
140
   b) Give prominent notice with the combined library that part of it
141
   is a work based on the Library, and explaining where to find the
142
   accompanying uncombined form of the same work.
143

    
144
  6. Revised Versions of the GNU Lesser General Public License.
145

    
146
  The Free Software Foundation may publish revised and/or new versions
147
of the GNU Lesser General Public License from time to time. Such new
148
versions will be similar in spirit to the present version, but may
149
differ in detail to address new problems or concerns.
150

    
151
  Each version is given a distinguishing version number. If the
152
Library as you received it specifies that a certain numbered version
153
of the GNU Lesser General Public License "or any later version"
154
applies to it, you have the option of following the terms and
155
conditions either of that published version or of any later version
156
published by the Free Software Foundation. If the Library as you
157
received it does not specify a version number of the GNU Lesser
158
General Public License, you may choose any version of the GNU Lesser
159
General Public License ever published by the Free Software Foundation.
160

    
161
  If the Library as you received it specifies that a proxy can decide
162
whether future versions of the GNU Lesser General Public License shall
163
apply, that proxy's public statement of acceptance of any version is
164
permanent authorization for you to choose that version for the
165
Library.
166

169
                    GNU GENERAL PUBLIC LICENSE
170
                       Version 3, 29 June 2007
171

    
172
 Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
173
 Everyone is permitted to copy and distribute verbatim copies
174
 of this license document, but changing it is not allowed.
175

    
176
                            Preamble
177

    
178
  The GNU General Public License is a free, copyleft license for
179
software and other kinds of works.
180

    
181
  The licenses for most software and other practical works are designed
182
to take away your freedom to share and change the works.  By contrast,
183
the GNU General Public License is intended to guarantee your freedom to
184
share and change all versions of a program--to make sure it remains free
185
software for all its users.  We, the Free Software Foundation, use the
186
GNU General Public License for most of our software; it applies also to
187
any other work released this way by its authors.  You can apply it to
188
your programs, too.
189

    
190
  When we speak of free software, we are referring to freedom, not
191
price.  Our General Public Licenses are designed to make sure that you
192
have the freedom to distribute copies of free software (and charge for
193
them if you wish), that you receive source code or can get it if you
194
want it, that you can change the software or use pieces of it in new
195
free programs, and that you know you can do these things.
196

    
197
  To protect your rights, we need to prevent others from denying you
198
these rights or asking you to surrender the rights.  Therefore, you have
199
certain responsibilities if you distribute copies of the software, or if
200
you modify it: responsibilities to respect the freedom of others.
201

    
202
  For example, if you distribute copies of such a program, whether
203
gratis or for a fee, you must pass on to the recipients the same
204
freedoms that you received.  You must make sure that they, too, receive
205
or can get the source code.  And you must show them these terms so they
206
know their rights.
207

    
208
  Developers that use the GNU GPL protect your rights with two steps:
209
(1) assert copyright on the software, and (2) offer you this License
210
giving you legal permission to copy, distribute and/or modify it.
211

    
212
  For the developers' and authors' protection, the GPL clearly explains
213
that there is no warranty for this free software.  For both users' and
214
authors' sake, the GPL requires that modified versions be marked as
215
changed, so that their problems will not be attributed erroneously to
216
authors of previous versions.
217

    
218
  Some devices are designed to deny users access to install or run
219
modified versions of the software inside them, although the manufacturer
220
can do so.  This is fundamentally incompatible with the aim of
221
protecting users' freedom to change the software.  The systematic
222
pattern of such abuse occurs in the area of products for individuals to
223
use, which is precisely where it is most unacceptable.  Therefore, we
224
have designed this version of the GPL to prohibit the practice for those
225
products.  If such problems arise substantially in other domains, we
226
stand ready to extend this provision to those domains in future versions
227
of the GPL, as needed to protect the freedom of users.
228

    
229
  Finally, every program is threatened constantly by software patents.
230
States should not allow patents to restrict development and use of
231
software on general-purpose computers, but in those that do, we wish to
232
avoid the special danger that patents applied to a free program could
233
make it effectively proprietary.  To prevent this, the GPL assures that
234
patents cannot be used to render the program non-free.
235

    
236
  The precise terms and conditions for copying, distribution and
237
modification follow.
238

    
239
                       TERMS AND CONDITIONS
240

    
241
  0. Definitions.
242

    
243
  "This License" refers to version 3 of the GNU General Public License.
244

    
245
  "Copyright" also means copyright-like laws that apply to other kinds of
246
works, such as semiconductor masks.
247

    
248
  "The Program" refers to any copyrightable work licensed under this
249
License.  Each licensee is addressed as "you".  "Licensees" and
250
"recipients" may be individuals or organizations.
251

    
252
  To "modify" a work means to copy from or adapt all or part of the work
253
in a fashion requiring copyright permission, other than the making of an
254
exact copy.  The resulting work is called a "modified version" of the
255
earlier work or a work "based on" the earlier work.
256

    
257
  A "covered work" means either the unmodified Program or a work based
258
on the Program.
259

    
260
  To "propagate" a work means to do anything with it that, without
261
permission, would make you directly or secondarily liable for
262
infringement under applicable copyright law, except executing it on a
263
computer or modifying a private copy.  Propagation includes copying,
264
distribution (with or without modification), making available to the
265
public, and in some countries other activities as well.
266

    
267
  To "convey" a work means any kind of propagation that enables other
268
parties to make or receive copies.  Mere interaction with a user through
269
a computer network, with no transfer of a copy, is not conveying.
270

    
271
  An interactive user interface displays "Appropriate Legal Notices"
272
to the extent that it includes a convenient and prominently visible
273
feature that (1) displays an appropriate copyright notice, and (2)
274
tells the user that there is no warranty for the work (except to the
275
extent that warranties are provided), that licensees may convey the
276
work under this License, and how to view a copy of this License.  If
277
the interface presents a list of user commands or options, such as a
278
menu, a prominent item in the list meets this criterion.
279

    
280
  1. Source Code.
281

    
282
  The "source code" for a work means the preferred form of the work
283
for making modifications to it.  "Object code" means any non-source
284
form of a work.
285

    
286
  A "Standard Interface" means an interface that either is an official
287
standard defined by a recognized standards body, or, in the case of
288
interfaces specified for a particular programming language, one that
289
is widely used among developers working in that language.
290

    
291
  The "System Libraries" of an executable work include anything, other
292
than the work as a whole, that (a) is included in the normal form of
293
packaging a Major Component, but which is not part of that Major
294
Component, and (b) serves only to enable use of the work with that
295
Major Component, or to implement a Standard Interface for which an
296
implementation is available to the public in source code form.  A
297
"Major Component", in this context, means a major essential component
298
(kernel, window system, and so on) of the specific operating system
299
(if any) on which the executable work runs, or a compiler used to
300
produce the work, or an object code interpreter used to run it.
301

    
302
  The "Corresponding Source" for a work in object code form means all
303
the source code needed to generate, install, and (for an executable
304
work) run the object code and to modify the work, including scripts to
305
control those activities.  However, it does not include the work's
306
System Libraries, or general-purpose tools or generally available free
307
programs which are used unmodified in performing those activities but
308
which are not part of the work.  For example, Corresponding Source
309
includes interface definition files associated with source files for
310
the work, and the source code for shared libraries and dynamically
311
linked subprograms that the work is specifically designed to require,
312
such as by intimate data communication or control flow between those
313
subprograms and other parts of the work.
314

    
315
  The Corresponding Source need not include anything that users
316
can regenerate automatically from other parts of the Corresponding
317
Source.
318

    
319
  The Corresponding Source for a work in source code form is that
320
same work.
321

    
322
  2. Basic Permissions.
323

    
324
  All rights granted under this License are granted for the term of
325
copyright on the Program, and are irrevocable provided the stated
326
conditions are met.  This License explicitly affirms your unlimited
327
permission to run the unmodified Program.  The output from running a
328
covered work is covered by this License only if the output, given its
329
content, constitutes a covered work.  This License acknowledges your
330
rights of fair use or other equivalent, as provided by copyright law.
331

    
332
  You may make, run and propagate covered works that you do not
333
convey, without conditions so long as your license otherwise remains
334
in force.  You may convey covered works to others for the sole purpose
335
of having them make modifications exclusively for you, or provide you
336
with facilities for running those works, provided that you comply with
337
the terms of this License in conveying all material for which you do
338
not control copyright.  Those thus making or running the covered works
339
for you must do so exclusively on your behalf, under your direction
340
and control, on terms that prohibit them from making any copies of
341
your copyrighted material outside their relationship with you.
342

    
343
  Conveying under any other circumstances is permitted solely under
344
the conditions stated below.  Sublicensing is not allowed; section 10
345
makes it unnecessary.
346

    
347
  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
348

    
349
  No covered work shall be deemed part of an effective technological
350
measure under any applicable law fulfilling obligations under article
351
11 of the WIPO copyright treaty adopted on 20 December 1996, or
352
similar laws prohibiting or restricting circumvention of such
353
measures.
354

    
355
  When you convey a covered work, you waive any legal power to forbid
356
circumvention of technological measures to the extent such circumvention
357
is effected by exercising rights under this License with respect to
358
the covered work, and you disclaim any intention to limit operation or
359
modification of the work as a means of enforcing, against the work's
360
users, your or third parties' legal rights to forbid circumvention of
361
technological measures.
362

    
363
  4. Conveying Verbatim Copies.
364

    
365
  You may convey verbatim copies of the Program's source code as you
366
receive it, in any medium, provided that you conspicuously and
367
appropriately publish on each copy an appropriate copyright notice;
368
keep intact all notices stating that this License and any
369
non-permissive terms added in accord with section 7 apply to the code;
370
keep intact all notices of the absence of any warranty; and give all
371
recipients a copy of this License along with the Program.
372

    
373
  You may charge any price or no price for each copy that you convey,
374
and you may offer support or warranty protection for a fee.
375

    
376
  5. Conveying Modified Source Versions.
377

    
378
  You may convey a work based on the Program, or the modifications to
379
produce it from the Program, in the form of source code under the
380
terms of section 4, provided that you also meet all of these conditions:
381

    
382
    a) The work must carry prominent notices stating that you modified
383
    it, and giving a relevant date.
384

    
385
    b) The work must carry prominent notices stating that it is
386
    released under this License and any conditions added under section
387
    7.  This requirement modifies the requirement in section 4 to
388
    "keep intact all notices".
389

    
390
    c) You must license the entire work, as a whole, under this
391
    License to anyone who comes into possession of a copy.  This
392
    License will therefore apply, along with any applicable section 7
393
    additional terms, to the whole of the work, and all its parts,
394
    regardless of how they are packaged.  This License gives no
395
    permission to license the work in any other way, but it does not
396
    invalidate such permission if you have separately received it.
397

    
398
    d) If the work has interactive user interfaces, each must display
399
    Appropriate Legal Notices; however, if the Program has interactive
400
    interfaces that do not display Appropriate Legal Notices, your
401
    work need not make them do so.
402

    
403
  A compilation of a covered work with other separate and independent
404
works, which are not by their nature extensions of the covered work,
405
and which are not combined with it such as to form a larger program,
406
in or on a volume of a storage or distribution medium, is called an
407
"aggregate" if the compilation and its resulting copyright are not
408
used to limit the access or legal rights of the compilation's users
409
beyond what the individual works permit.  Inclusion of a covered work
410
in an aggregate does not cause this License to apply to the other
411
parts of the aggregate.
412

    
413
  6. Conveying Non-Source Forms.
414

    
415
  You may convey a covered work in object code form under the terms
416
of sections 4 and 5, provided that you also convey the
417
machine-readable Corresponding Source under the terms of this License,
418
in one of these ways:
419

    
420
    a) Convey the object code in, or embodied in, a physical product
421
    (including a physical distribution medium), accompanied by the
422
    Corresponding Source fixed on a durable physical medium
423
    customarily used for software interchange.
424

    
425
    b) Convey the object code in, or embodied in, a physical product
426
    (including a physical distribution medium), accompanied by a
427
    written offer, valid for at least three years and valid for as
428
    long as you offer spare parts or customer support for that product
429
    model, to give anyone who possesses the object code either (1) a
430
    copy of the Corresponding Source for all the software in the
431
    product that is covered by this License, on a durable physical
432
    medium customarily used for software interchange, for a price no
433
    more than your reasonable cost of physically performing this
434
    conveying of source, or (2) access to copy the
435
    Corresponding Source from a network server at no charge.
436

    
437
    c) Convey individual copies of the object code with a copy of the
438
    written offer to provide the Corresponding Source.  This
439
    alternative is allowed only occasionally and noncommercially, and
440
    only if you received the object code with such an offer, in accord
441
    with subsection 6b.
442

    
443
    d) Convey the object code by offering access from a designated
444
    place (gratis or for a charge), and offer equivalent access to the
445
    Corresponding Source in the same way through the same place at no
446
    further charge.  You need not require recipients to copy the
447
    Corresponding Source along with the object code.  If the place to
448
    copy the object code is a network server, the Corresponding Source
449
    may be on a different server (operated by you or a third party)
450
    that supports equivalent copying facilities, provided you maintain
451
    clear directions next to the object code saying where to find the
452
    Corresponding Source.  Regardless of what server hosts the
453
    Corresponding Source, you remain obligated to ensure that it is
454
    available for as long as needed to satisfy these requirements.
455

    
456
    e) Convey the object code using peer-to-peer transmission, provided
457
    you inform other peers where the object code and Corresponding
458
    Source of the work are being offered to the general public at no
459
    charge under subsection 6d.
460

    
461
  A separable portion of the object code, whose source code is excluded
462
from the Corresponding Source as a System Library, need not be
463
included in conveying the object code work.
464

    
465
  A "User Product" is either (1) a "consumer product", which means any
466
tangible personal property which is normally used for personal, family,
467
or household purposes, or (2) anything designed or sold for incorporation
468
into a dwelling.  In determining whether a product is a consumer product,
469
doubtful cases shall be resolved in favor of coverage.  For a particular
470
product received by a particular user, "normally used" refers to a
471
typical or common use of that class of product, regardless of the status
472
of the particular user or of the way in which the particular user
473
actually uses, or expects or is expected to use, the product.  A product
474
is a consumer product regardless of whether the product has substantial
475
commercial, industrial or non-consumer uses, unless such uses represent
476
the only significant mode of use of the product.
477

    
478
  "Installation Information" for a User Product means any methods,
479
procedures, authorization keys, or other information required to install
480
and execute modified versions of a covered work in that User Product from
481
a modified version of its Corresponding Source.  The information must
482
suffice to ensure that the continued functioning of the modified object
483
code is in no case prevented or interfered with solely because
484
modification has been made.
485

    
486
  If you convey an object code work under this section in, or with, or
487
specifically for use in, a User Product, and the conveying occurs as
488
part of a transaction in which the right of possession and use of the
489
User Product is transferred to the recipient in perpetuity or for a
490
fixed term (regardless of how the transaction is characterized), the
491
Corresponding Source conveyed under this section must be accompanied
492
by the Installation Information.  But this requirement does not apply
493
if neither you nor any third party retains the ability to install
494
modified object code on the User Product (for example, the work has
495
been installed in ROM).
496

    
497
  The requirement to provide Installation Information does not include a
498
requirement to continue to provide support service, warranty, or updates
499
for a work that has been modified or installed by the recipient, or for
500
the User Product in which it has been modified or installed.  Access to a
501
network may be denied when the modification itself materially and
502
adversely affects the operation of the network or violates the rules and
503
protocols for communication across the network.
504

    
505
  Corresponding Source conveyed, and Installation Information provided,
506
in accord with this section must be in a format that is publicly
507
documented (and with an implementation available to the public in
508
source code form), and must require no special password or key for
509
unpacking, reading or copying.
510

    
511
  7. Additional Terms.
512

    
513
  "Additional permissions" are terms that supplement the terms of this
514
License by making exceptions from one or more of its conditions.
515
Additional permissions that are applicable to the entire Program shall
516
be treated as though they were included in this License, to the extent
517
that they are valid under applicable law.  If additional permissions
518
apply only to part of the Program, that part may be used separately
519
under those permissions, but the entire Program remains governed by
520
this License without regard to the additional permissions.
521

    
522
  When you convey a copy of a covered work, you may at your option
523
remove any additional permissions from that copy, or from any part of
524
it.  (Additional permissions may be written to require their own
525
removal in certain cases when you modify the work.)  You may place
526
additional permissions on material, added by you to a covered work,
527
for which you have or can give appropriate copyright permission.
528

    
529
  Notwithstanding any other provision of this License, for material you
530
add to a covered work, you may (if authorized by the copyright holders of
531
that material) supplement the terms of this License with terms:
532

    
533
    a) Disclaiming warranty or limiting liability differently from the
534
    terms of sections 15 and 16 of this License; or
535

    
536
    b) Requiring preservation of specified reasonable legal notices or
537
    author attributions in that material or in the Appropriate Legal
538
    Notices displayed by works containing it; or
539

    
540
    c) Prohibiting misrepresentation of the origin of that material, or
541
    requiring that modified versions of such material be marked in
542
    reasonable ways as different from the original version; or
543

    
544
    d) Limiting the use for publicity purposes of names of licensors or
545
    authors of the material; or
546

    
547
    e) Declining to grant rights under trademark law for use of some
548
    trade names, trademarks, or service marks; or
549

    
550
    f) Requiring indemnification of licensors and authors of that
551
    material by anyone who conveys the material (or modified versions of
552
    it) with contractual assumptions of liability to the recipient, for
553
    any liability that these contractual assumptions directly impose on
554
    those licensors and authors.
555

    
556
  All other non-permissive additional terms are considered "further
557
restrictions" within the meaning of section 10.  If the Program as you
558
received it, or any part of it, contains a notice stating that it is
559
governed by this License along with a term that is a further
560
restriction, you may remove that term.  If a license document contains
561
a further restriction but permits relicensing or conveying under this
562
License, you may add to a covered work material governed by the terms
563
of that license document, provided that the further restriction does
564
not survive such relicensing or conveying.
565

    
566
  If you add terms to a covered work in accord with this section, you
567
must place, in the relevant source files, a statement of the
568
additional terms that apply to those files, or a notice indicating
569
where to find the applicable terms.
570

    
571
  Additional terms, permissive or non-permissive, may be stated in the
572
form of a separately written license, or stated as exceptions;
573
the above requirements apply either way.
574

    
575
  8. Termination.
576

    
577
  You may not propagate or modify a covered work except as expressly
578
provided under this License.  Any attempt otherwise to propagate or
579
modify it is void, and will automatically terminate your rights under
580
this License (including any patent licenses granted under the third
581
paragraph of section 11).
582

    
583
  However, if you cease all violation of this License, then your
584
license from a particular copyright holder is reinstated (a)
585
provisionally, unless and until the copyright holder explicitly and
586
finally terminates your license, and (b) permanently, if the copyright
587
holder fails to notify you of the violation by some reasonable means
588
prior to 60 days after the cessation.
589

    
590
  Moreover, your license from a particular copyright holder is
591
reinstated permanently if the copyright holder notifies you of the
592
violation by some reasonable means, this is the first time you have
593
received notice of violation of this License (for any work) from that
594
copyright holder, and you cure the violation prior to 30 days after
595
your receipt of the notice.
596

    
597
  Termination of your rights under this section does not terminate the
598
licenses of parties who have received copies or rights from you under
599
this License.  If your rights have been terminated and not permanently
600
reinstated, you do not qualify to receive new licenses for the same
601
material under section 10.
602

    
603
  9. Acceptance Not Required for Having Copies.
604

    
605
  You are not required to accept this License in order to receive or
606
run a copy of the Program.  Ancillary propagation of a covered work
607
occurring solely as a consequence of using peer-to-peer transmission
608
to receive a copy likewise does not require acceptance.  However,
609
nothing other than this License grants you permission to propagate or
610
modify any covered work.  These actions infringe copyright if you do
611
not accept this License.  Therefore, by modifying or propagating a
612
covered work, you indicate your acceptance of this License to do so.
613

    
614
  10. Automatic Licensing of Downstream Recipients.
615

    
616
  Each time you convey a covered work, the recipient automatically
617
receives a license from the original licensors, to run, modify and
618
propagate that work, subject to this License.  You are not responsible
619
for enforcing compliance by third parties with this License.
620

    
621
  An "entity transaction" is a transaction transferring control of an
622
organization, or substantially all assets of one, or subdividing an
623
organization, or merging organizations.  If propagation of a covered
624
work results from an entity transaction, each party to that
625
transaction who receives a copy of the work also receives whatever
626
licenses to the work the party's predecessor in interest had or could
627
give under the previous paragraph, plus a right to possession of the
628
Corresponding Source of the work from the predecessor in interest, if
629
the predecessor has it or can get it with reasonable efforts.
630

    
631
  You may not impose any further restrictions on the exercise of the
632
rights granted or affirmed under this License.  For example, you may
633
not impose a license fee, royalty, or other charge for exercise of
634
rights granted under this License, and you may not initiate litigation
635
(including a cross-claim or counterclaim in a lawsuit) alleging that
636
any patent claim is infringed by making, using, selling, offering for
637
sale, or importing the Program or any portion of it.
638

    
639
  11. Patents.
640

    
641
  A "contributor" is a copyright holder who authorizes use under this
642
License of the Program or a work on which the Program is based.  The
643
work thus licensed is called the contributor's "contributor version".
644

    
645
  A contributor's "essential patent claims" are all patent claims
646
owned or controlled by the contributor, whether already acquired or
647
hereafter acquired, that would be infringed by some manner, permitted
648
by this License, of making, using, or selling its contributor version,
649
but do not include claims that would be infringed only as a
650
consequence of further modification of the contributor version.  For
651
purposes of this definition, "control" includes the right to grant
652
patent sublicenses in a manner consistent with the requirements of
653
this License.
654

    
655
  Each contributor grants you a non-exclusive, worldwide, royalty-free
656
patent license under the contributor's essential patent claims, to
657
make, use, sell, offer for sale, import and otherwise run, modify and
658
propagate the contents of its contributor version.
659

    
660
  In the following three paragraphs, a "patent license" is any express
661
agreement or commitment, however denominated, not to enforce a patent
662
(such as an express permission to practice a patent or covenant not to
663
sue for patent infringement).  To "grant" such a patent license to a
664
party means to make such an agreement or commitment not to enforce a
665
patent against the party.
666

    
667
  If you convey a covered work, knowingly relying on a patent license,
668
and the Corresponding Source of the work is not available for anyone
669
to copy, free of charge and under the terms of this License, through a
670
publicly available network server or other readily accessible means,
671
then you must either (1) cause the Corresponding Source to be so
672
available, or (2) arrange to deprive yourself of the benefit of the
673
patent license for this particular work, or (3) arrange, in a manner
674
consistent with the requirements of this License, to extend the patent
675
license to downstream recipients.  "Knowingly relying" means you have
676
actual knowledge that, but for the patent license, your conveying the
677
covered work in a country, or your recipient's use of the covered work
678
in a country, would infringe one or more identifiable patents in that
679
country that you have reason to believe are valid.
680

    
681
  If, pursuant to or in connection with a single transaction or
682
arrangement, you convey, or propagate by procuring conveyance of, a
683
covered work, and grant a patent license to some of the parties
684
receiving the covered work authorizing them to use, propagate, modify
685
or convey a specific copy of the covered work, then the patent license
686
you grant is automatically extended to all recipients of the covered
687
work and works based on it.
688

    
689
  A patent license is "discriminatory" if it does not include within
690
the scope of its coverage, prohibits the exercise of, or is
691
conditioned on the non-exercise of one or more of the rights that are
692
specifically granted under this License.  You may not convey a covered
693
work if you are a party to an arrangement with a third party that is
694
in the business of distributing software, under which you make payment
695
to the third party based on the extent of your activity of conveying
696
the work, and under which the third party grants, to any of the
697
parties who would receive the covered work from you, a discriminatory
698
patent license (a) in connection with copies of the covered work
699
conveyed by you (or copies made from those copies), or (b) primarily
700
for and in connection with specific products or compilations that
701
contain the covered work, unless you entered into that arrangement,
702
or that patent license was granted, prior to 28 March 2007.
703

    
704
  Nothing in this License shall be construed as excluding or limiting
705
any implied license or other defenses to infringement that may
706
otherwise be available to you under applicable patent law.
707

    
708
  12. No Surrender of Others' Freedom.
709

    
710
  If conditions are imposed on you (whether by court order, agreement or
711
otherwise) that contradict the conditions of this License, they do not
712
excuse you from the conditions of this License.  If you cannot convey a
713
covered work so as to satisfy simultaneously your obligations under this
714
License and any other pertinent obligations, then as a consequence you may
715
not convey it at all.  For example, if you agree to terms that obligate you
716
to collect a royalty for further conveying from those to whom you convey
717
the Program, the only way you could satisfy both those terms and this
718
License would be to refrain entirely from conveying the Program.
719

    
720
  13. Use with the GNU Affero General Public License.
721

    
722
  Notwithstanding any other provision of this License, you have
723
permission to link or combine any covered work with a work licensed
724
under version 3 of the GNU Affero General Public License into a single
725
combined work, and to convey the resulting work.  The terms of this
726
License will continue to apply to the part which is the covered work,
727
but the special requirements of the GNU Affero General Public License,
728
section 13, concerning interaction through a network will apply to the
729
combination as such.
730

    
731
  14. Revised Versions of this License.
732

    
733
  The Free Software Foundation may publish revised and/or new versions of
734
the GNU General Public License from time to time.  Such new versions will
735
be similar in spirit to the present version, but may differ in detail to
736
address new problems or concerns.
737

    
738
  Each version is given a distinguishing version number.  If the
739
Program specifies that a certain numbered version of the GNU General
740
Public License "or any later version" applies to it, you have the
741
option of following the terms and conditions either of that numbered
742
version or of any later version published by the Free Software
743
Foundation.  If the Program does not specify a version number of the
744
GNU General Public License, you may choose any version ever published
745
by the Free Software Foundation.
746

    
747
  If the Program specifies that a proxy can decide which future
748
versions of the GNU General Public License can be used, that proxy's
749
public statement of acceptance of a version permanently authorizes you
750
to choose that version for the Program.
751

    
752
  Later license versions may give you additional or different
753
permissions.  However, no additional obligations are imposed on any
754
author or copyright holder as a result of your choosing to follow a
755
later version.
756

    
757
  15. Disclaimer of Warranty.
758

    
759
  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
760
APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
761
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
762
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
763
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
764
PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
765
IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
766
ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
767

    
768
  16. Limitation of Liability.
769

    
770
  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
771
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
772
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
773
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
774
USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
775
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
776
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
777
EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
778
SUCH DAMAGES.
779

    
780
  17. Interpretation of Sections 15 and 16.
781

    
782
  If the disclaimer of warranty and limitation of liability provided
783
above cannot be given local legal effect according to their terms,
784
reviewing courts shall apply local law that most closely approximates
785
an absolute waiver of all civil liability in connection with the
786
Program, unless a warranty or assumption of liability accompanies a
787
copy of the Program in return for a fee.
788

    
789
                     END OF TERMS AND CONDITIONS
790

    
791
            How to Apply These Terms to Your New Programs
792

    
793
  If you develop a new program, and you want it to be of the greatest
794
possible use to the public, the best way to achieve this is to make it
795
free software which everyone can redistribute and change under these terms.
796

    
797
  To do so, attach the following notices to the program.  It is safest
798
to attach them to the start of each source file to most effectively
799
state the exclusion of warranty; and each file should have at least
800
the "copyright" line and a pointer to where the full notice is found.
801

    
802
    <one line to give the program's name and a brief idea of what it does.>
803
    Copyright (C) <year>  <name of author>
804

    
805
    This program is free software: you can redistribute it and/or modify
806
    it under the terms of the GNU General Public License as published by
807
    the Free Software Foundation, either version 3 of the License, or
808
    (at your option) any later version.
809

    
810
    This program is distributed in the hope that it will be useful,
811
    but WITHOUT ANY WARRANTY; without even the implied warranty of
812
    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
813
    GNU General Public License for more details.
814

    
815
    You should have received a copy of the GNU General Public License
816
    along with this program.  If not, see <http://www.gnu.org/licenses/>.
817

    
818
Also add information on how to contact you by electronic and paper mail.
819

    
820
  If the program does terminal interaction, make it output a short
821
notice like this when it starts in an interactive mode:
822

    
823
    <program>  Copyright (C) <year>  <name of author>
824
    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
825
    This is free software, and you are welcome to redistribute it
826
    under certain conditions; type `show c' for details.
827

    
828
The hypothetical commands `show w' and `show c' should show the appropriate
829
parts of the General Public License.  Of course, your program's commands
830
might be different; for a GUI interface, you would use an "about box".
831

    
832
  You should also get your employer (if you work as a programmer) or school,
833
if any, to sign a "copyright disclaimer" for the program, if necessary.
834

835
<http://www.gnu.org/licenses/>.
836

    
837
  The GNU General Public License does not permit incorporating your program
838
into proprietary programs.  If your program is a subroutine library, you
839
may consider it more useful to permit linking proprietary applications with
840
the library.  If this is what you want to do, use the GNU Lesser General
841
Public License instead of this License.  But first, please read
842
<http://www.gnu.org/philosophy/why-not-lgpl.html>.
