                   GNU LESSER GENERAL PUBLIC LICENSE
14
                       Version 3, 29 June 2007
15

    
16
 Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
17
 Everyone is permitted to copy and distribute verbatim copies
18
 of this license document, but changing it is not allowed.
19

    
20

    
21
  This version of the GNU Lesser General Public License incorporates
22
the terms and conditions of version 3 of the GNU General Public
23
License, supplemented by the additional permissions listed below.
24

    
25
  0. Additional Definitions.
26

    
27
  As used herein, "this License" refers to version 3 of the GNU Lesser
28
General Public License, and the "GNU GPL" refers to version 3 of the GNU
29
General Public License.
30

    
31
  "The Library" refers to a covered work governed by this License,
32
other than an Application or a Combined Work as defined below.
33

    
34
  An "Application" is any work that makes use of an interface provided
35
by the Library, but which is not otherwise based on the Library.
36
Defining a subclass of a class defined by the Library is deemed a mode
37
of using an interface provided by the Library.
38

    
39
  A "Combined Work" is a work produced by combining or linking an
40
Application with the Library.  The particular version of the Library
41
with which the Combined Work was made is also called the "Linked
42
Version".
43

    
44
  The "Minimal Corresponding Source" for a Combined Work means the
45
Corresponding Source for the Combined Work, excluding any source code
46
for portions of the Combined Work that, considered in isolation, are
47
based on the Application, and not on the Linked Version.
48

    
49
  The "Corresponding Application Code" for a Combined Work means the
50
object code and/or source code for the Application, including any data
51
and utility programs needed for reproducing the Combined Work from the
52
Application, but excluding the System Libraries of the Combined Work.
53

    
54
  1. Exception to Section 3 of the GNU GPL.
55

    
56
  You may convey a covered work under sections 3 and 4 of this License
57
without being bound by section 3 of the GNU GPL.
58

    
59
  2. Conveying Modified Versions.
60

    
61
  If you modify a copy of the Library, and, in your modifications, a
62
facility refers to a function or data to be supplied by an Application
63
that uses the facility (other than as an argument passed when the
64
facility is invoked), then you may convey a copy of the modified
65
version:
66

    
67
   a) under this License, provided that you make a good faith effort to
68
   ensure that, in the event an Application does not supply the
69
   function or data, the facility still operates, and performs
70
   whatever part of its purpose remains meaningful, or
71

    
72
   b) under the GNU GPL, with none of the additional permissions of
73
   this License applicable to that copy.
74

    
75
  3. Object Code Incorporating Material from Library Header Files.
76

    
77
  The object code form of an Application may incorporate material from
78
a header file that is part of the Library.  You may convey such object
79
code under terms of your choice, provided that, if the incorporated
80
material is not limited to numerical parameters, data structure
81
layouts and accessors, or small macros, inline functions and templates
82
(ten or fewer lines in length), you do both of the following:
83

    
84
   a) Give prominent notice with each copy of the object code that the
85
   Library is used in it and that the Library and its use are
86
   covered by this License.
87

    
88
   b) Accompany the object code with a copy of the GNU GPL and this license
89
   document.
90

    
91
  4. Combined Works.
92

    
93
  You may convey a Combined Work under terms of your choice that,
94
taken together, effectively do not restrict modification of the
95
portions of the Library contained in the Combined Work and reverse
96
engineering for debugging such modifications, if you also do each of
97
the following:
98

    
99
   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.
102

    
103
   b) Accompany the Combined Work with a copy of the GNU GPL and this license
104
   document.
105

    
106
   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.
110

    
111
   d) Do one of the following:
112

    
113
       0) Convey the Minimal Corresponding Source under the terms of this
114
       License, and the Corresponding Application Code in a form
115
       suitable for, and under terms that permit, the user to
116
       recombine or relink the Application with a modified version of
117
       the Linked Version to produce a modified Combined Work, in the
118
       manner specified by section 6 of the GNU GPL for conveying
119
       Corresponding Source.
120

    
121
       1) Use a suitable shared library mechanism for linking with the
122
       Library.  A suitable mechanism is one that (a) uses at run time
123
       a copy of the Library already present on the user's computer
124
       system, and (b) will operate properly with a modified version
125
       of the Library that is interface-compatible with the Linked
126
       Version.
127

    
128
   e) Provide Installation Information, but only if you would otherwise
129
   be required to provide such information under section 6 of the
130
   GNU GPL, and only to the extent that such information is
131
   necessary to install and execute a modified version of the
132
   Combined Work produced by recombining or relinking the
133
   Application with a modified version of the Linked Version. (If
134
   you use option 4d0, the Installation Information must accompany
135
   the Minimal Corresponding Source and Corresponding Application
136
   Code. If you use option 4d1, you must provide the Installation
137
   Information in the manner specified by section 6 of the GNU GPL
138
   for conveying Corresponding Source.)
139

    
140
  5. Combined Libraries.
141

    
142
  You may place library facilities that are a work based on the
143
Library side by side in a single library together with other library
144
facilities that are not Applications and are not covered by this
145
License, and convey such a combined library under terms of your
146
choice, if you do both of the following:
147

    
148
   a) Accompany the combined library with a copy of the same work based
149
   on the Library, uncombined with any other library facilities,
150
   conveyed under the terms of this License.
151

    
152
   b) Give prominent notice with the combined library that part of it
153
   is a work based on the Library, and explaining where to find the
154
   accompanying uncombined form of the same work.
155

    
156
  6. Revised Versions of the GNU Lesser General Public License.
157

    
158
  The Free Software Foundation may publish revised and/or new versions
159
of the GNU Lesser General Public License from time to time. Such new
160
versions will be similar in spirit to the present version, but may
161
differ in detail to address new problems or concerns.
162

    
163
  Each version is given a distinguishing version number. If the
164
Library as you received it specifies that a certain numbered version
165
of the GNU Lesser General Public License "or any later version"
166
applies to it, you have the option of following the terms and
167
conditions either of that published version or of any later version
168
published by the Free Software Foundation. If the Library as you
169
received it does not specify a version number of the GNU Lesser
170
General Public License, you may choose any version of the GNU Lesser
171
General Public License ever published by the Free Software Foundation.
172

    
173
  If the Library as you received it specifies that a proxy can decide
174
whether future versions of the GNU Lesser General Public License shall
175
apply, that proxy's public statement of acceptance of any version is
176
permanent authorization for you to choose that version for the
177
Library.
178

                    GNU GENERAL PUBLIC LICENSE
183
                       Version 3, 29 June 2007
184

    
185
 Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
186
 Everyone is permitted to copy and distribute verbatim copies
187
 of this license document, but changing it is not allowed.
188

    
189
                            Preamble
190

    
191
  The GNU General Public License is a free, copyleft license for
192
software and other kinds of works.
193

    
194
  The licenses for most software and other practical works are designed
195
to take away your freedom to share and change the works.  By contrast,
196
the GNU General Public License is intended to guarantee your freedom to
197
share and change all versions of a program--to make sure it remains free
198
software for all its users.  We, the Free Software Foundation, use the
199
GNU General Public License for most of our software; it applies also to
200
any other work released this way by its authors.  You can apply it to
201
your programs, too.
202

    
203
  When we speak of free software, we are referring to freedom, not
204
price.  Our General Public Licenses are designed to make sure that you
205
have the freedom to distribute copies of free software (and charge for
206
them if you wish), that you receive source code or can get it if you
207
want it, that you can change the software or use pieces of it in new
208
free programs, and that you know you can do these things.
209

    
210
  To protect your rights, we need to prevent others from denying you
211
these rights or asking you to surrender the rights.  Therefore, you have
212
certain responsibilities if you distribute copies of the software, or if
213
you modify it: responsibilities to respect the freedom of others.
214

    
215
  For example, if you distribute copies of such a program, whether
216
gratis or for a fee, you must pass on to the recipients the same
217
freedoms that you received.  You must make sure that they, too, receive
218
or can get the source code.  And you must show them these terms so they
219
know their rights.
220

    
221
  Developers that use the GNU GPL protect your rights with two steps:
222
(1) assert copyright on the software, and (2) offer you this License
223
giving you legal permission to copy, distribute and/or modify it.
224

    
225
  For the developers' and authors' protection, the GPL clearly explains
226
that there is no warranty for this free software.  For both users' and
227
authors' sake, the GPL requires that modified versions be marked as
228
changed, so that their problems will not be attributed erroneously to
229
authors of previous versions.
230

    
231
  Some devices are designed to deny users access to install or run
232
modified versions of the software inside them, although the manufacturer
233
can do so.  This is fundamentally incompatible with the aim of
234
protecting users' freedom to change the software.  The systematic
235
pattern of such abuse occurs in the area of products for individuals to
236
use, which is precisely where it is most unacceptable.  Therefore, we
237
have designed this version of the GPL to prohibit the practice for those
238
products.  If such problems arise substantially in other domains, we
239
stand ready to extend this provision to those domains in future versions
240
of the GPL, as needed to protect the freedom of users.
241

    
242
  Finally, every program is threatened constantly by software patents.
243
States should not allow patents to restrict development and use of
244
software on general-purpose computers, but in those that do, we wish to
245
avoid the special danger that patents applied to a free program could
246
make it effectively proprietary.  To prevent this, the GPL assures that
247
patents cannot be used to render the program non-free.
248

    
249
  The precise terms and conditions for copying, distribution and
250
modification follow.
251

    
252
                       TERMS AND CONDITIONS
253

    
254
  0. Definitions.
255

    
256
  "This License" refers to version 3 of the GNU General Public License.
257

    
258
  "Copyright" also means copyright-like laws that apply to other kinds of
259
works, such as semiconductor masks.
260

    
261
  "The Program" refers to any copyrightable work licensed under this
262
License.  Each licensee is addressed as "you".  "Licensees" and
263
"recipients" may be individuals or organizations.
264

    
265
  To "modify" a work means to copy from or adapt all or part of the work
266
in a fashion requiring copyright permission, other than the making of an
267
exact copy.  The resulting work is called a "modified version" of the
268
earlier work or a work "based on" the earlier work.
269

    
270
  A "covered work" means either the unmodified Program or a work based
271
on the Program.
272

    
273
  To "propagate" a work means to do anything with it that, without
274
permission, would make you directly or secondarily liable for
275
infringement under applicable copyright law, except executing it on a
276
computer or modifying a private copy.  Propagation includes copying,
277
distribution (with or without modification), making available to the
278
public, and in some countries other activities as well.
279

    
280
  To "convey" a work means any kind of propagation that enables other
281
parties to make or receive copies.  Mere interaction with a user through
282
a computer network, with no transfer of a copy, is not conveying.
283

    
284
  An interactive user interface displays "Appropriate Legal Notices"
285
to the extent that it includes a convenient and prominently visible
286
feature that (1) displays an appropriate copyright notice, and (2)
287
tells the user that there is no warranty for the work (except to the
288
extent that warranties are provided), that licensees may convey the
289
work under this License, and how to view a copy of this License.  If
290
the interface presents a list of user commands or options, such as a
291
menu, a prominent item in the list meets this criterion.
292

    
293
  1. Source Code.
294

    
295
  The "source code" for a work means the preferred form of the work
296
for making modifications to it.  "Object code" means any non-source
297
form of a work.
298

    
299
  A "Standard Interface" means an interface that either is an official
300
standard defined by a recognized standards body, or, in the case of
301
interfaces specified for a particular programming language, one that
302
is widely used among developers working in that language.
303

    
304
  The "System Libraries" of an executable work include anything, other
305
than the work as a whole, that (a) is included in the normal form of
306
packaging a Major Component, but which is not part of that Major
307
Component, and (b) serves only to enable use of the work with that
308
Major Component, or to implement a Standard Interface for which an
309
implementation is available to the public in source code form.  A
310
"Major Component", in this context, means a major essential component
311
(kernel, window system, and so on) of the specific operating system
312
(if any) on which the executable work runs, or a compiler used to
313
produce the work, or an object code interpreter used to run it.
314

    
315
  The "Corresponding Source" for a work in object code form means all
316
the source code needed to generate, install, and (for an executable
317
work) run the object code and to modify the work, including scripts to
318
control those activities.  However, it does not include the work's
319
System Libraries, or general-purpose tools or generally available free
320
programs which are used unmodified in performing those activities but
321
which are not part of the work.  For example, Corresponding Source
322
includes interface definition files associated with source files for
323
the work, and the source code for shared libraries and dynamically
324
linked subprograms that the work is specifically designed to require,
325
such as by intimate data communication or control flow between those
326
subprograms and other parts of the work.
327

    
328
  The Corresponding Source need not include anything that users
329
can regenerate automatically from other parts of the Corresponding
330
Source.
331

    
332
  The Corresponding Source for a work in source code form is that
333
same work.
334

    
335
  2. Basic Permissions.
336

    
337
  All rights granted under this License are granted for the term of
338
copyright on the Program, and are irrevocable provided the stated
339
conditions are met.  This License explicitly affirms your unlimited
340
permission to run the unmodified Program.  The output from running a
341
covered work is covered by this License only if the output, given its
342
content, constitutes a covered work.  This License acknowledges your
343
rights of fair use or other equivalent, as provided by copyright law.
344

    
345
  You may make, run and propagate covered works that you do not
346
convey, without conditions so long as your license otherwise remains
347
in force.  You may convey covered works to others for the sole purpose
348
of having them make modifications exclusively for you, or provide you
349
with facilities for running those works, provided that you comply with
350
the terms of this License in conveying all material for which you do
351
not control copyright.  Those thus making or running the covered works
352
for you must do so exclusively on your behalf, under your direction
353
and control, on terms that prohibit them from making any copies of
354
your copyrighted material outside their relationship with you.
355

    
356
  Conveying under any other circumstances is permitted solely under
357
the conditions stated below.  Sublicensing is not allowed; section 10
358
makes it unnecessary.
359

    
360
  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
361

    
362
  No covered work shall be deemed part of an effective technological
363
measure under any applicable law fulfilling obligations under article
364
11 of the WIPO copyright treaty adopted on 20 December 1996, or
365
similar laws prohibiting or restricting circumvention of such
366
measures.
367

    
368
  When you convey a covered work, you waive any legal power to forbid
369
circumvention of technological measures to the extent such circumvention
370
is effected by exercising rights under this License with respect to
371
the covered work, and you disclaim any intention to limit operation or
372
modification of the work as a means of enforcing, against the work's
373
users, your or third parties' legal rights to forbid circumvention of
374
technological measures.
375

    
376
  4. Conveying Verbatim Copies.
377

    
378
  You may convey verbatim copies of the Program's source code as you
379
receive it, in any medium, provided that you conspicuously and
380
appropriately publish on each copy an appropriate copyright notice;
381
keep intact all notices stating that this License and any
382
non-permissive terms added in accord with section 7 apply to the code;
383
keep intact all notices of the absence of any warranty; and give all
384
recipients a copy of this License along with the Program.
385

    
386
  You may charge any price or no price for each copy that you convey,
387
and you may offer support or warranty protection for a fee.
388

    
389
  5. Conveying Modified Source Versions.
390

    
391
  You may convey a work based on the Program, or the modifications to
392
produce it from the Program, in the form of source code under the
393
terms of section 4, provided that you also meet all of these conditions:
394

    
395
    a) The work must carry prominent notices stating that you modified
396
    it, and giving a relevant date.
397

    
398
    b) The work must carry prominent notices stating that it is
399
    released under this License and any conditions added under section
400
    7.  This requirement modifies the requirement in section 4 to
401
    "keep intact all notices".
402

    
403
    c) You must license the entire work, as a whole, under this
404
    License to anyone who comes into possession of a copy.  This
405
    License will therefore apply, along with any applicable section 7
406
    additional terms, to the whole of the work, and all its parts,
407
    regardless of how they are packaged.  This License gives no
408
    permission to license the work in any other way, but it does not
409
    invalidate such permission if you have separately received it.
410

    
411
    d) If the work has interactive user interfaces, each must display
412
    Appropriate Legal Notices; however, if the Program has interactive
413
    interfaces that do not display Appropriate Legal Notices, your
414
    work need not make them do so.
415

    
416
  A compilation of a covered work with other separate and independent
417
works, which are not by their nature extensions of the covered work,
418
and which are not combined with it such as to form a larger program,
419
in or on a volume of a storage or distribution medium, is called an
420
"aggregate" if the compilation and its resulting copyright are not
421
used to limit the access or legal rights of the compilation's users
422
beyond what the individual works permit.  Inclusion of a covered work
423
in an aggregate does not cause this License to apply to the other
424
parts of the aggregate.
425

    
426
  6. Conveying Non-Source Forms.
427

    
428
  You may convey a covered work in object code form under the terms
429
of sections 4 and 5, provided that you also convey the
430
machine-readable Corresponding Source under the terms of this License,
431
in one of these ways:
432

    
433
    a) Convey the object code in, or embodied in, a physical product
434
    (including a physical distribution medium), accompanied by the
435
    Corresponding Source fixed on a durable physical medium
436
    customarily used for software interchange.
437

    
438
    b) Convey the object code in, or embodied in, a physical product
439
    (including a physical distribution medium), accompanied by a
440
    written offer, valid for at least three years and valid for as
441
    long as you offer spare parts or customer support for that product
442
    model, to give anyone who possesses the object code either (1) a
443
    copy of the Corresponding Source for all the software in the
444
    product that is covered by this License, on a durable physical
445
    medium customarily used for software interchange, for a price no
446
    more than your reasonable cost of physically performing this
447
    conveying of source, or (2) access to copy the
448
    Corresponding Source from a network server at no charge.
449

    
450
    c) Convey individual copies of the object code with a copy of the
451
    written offer to provide the Corresponding Source.  This
452
    alternative is allowed only occasionally and noncommercially, and
453
    only if you received the object code with such an offer, in accord
454
    with subsection 6b.
455

    
456
    d) Convey the object code by offering access from a designated
457
    place (gratis or for a charge), and offer equivalent access to the
458
    Corresponding Source in the same way through the same place at no
459
    further charge.  You need not require recipients to copy the
460
    Corresponding Source along with the object code.  If the place to
461
    copy the object code is a network server, the Corresponding Source
462
    may be on a different server (operated by you or a third party)
463
    that supports equivalent copying facilities, provided you maintain
464
    clear directions next to the object code saying where to find the
465
    Corresponding Source.  Regardless of what server hosts the
466
    Corresponding Source, you remain obligated to ensure that it is
467
    available for as long as needed to satisfy these requirements.
468

    
469
    e) Convey the object code using peer-to-peer transmission, provided
470
    you inform other peers where the object code and Corresponding
471
    Source of the work are being offered to the general public at no
472
    charge under subsection 6d.
473

    
474
  A separable portion of the object code, whose source code is excluded
475
from the Corresponding Source as a System Library, need not be
476
included in conveying the object code work.
477

    
478
  A "User Product" is either (1) a "consumer product", which means any
479
tangible personal property which is normally used for personal, family,
480
or household purposes, or (2) anything designed or sold for incorporation
481
into a dwelling.  In determining whether a product is a consumer product,
482
doubtful cases shall be resolved in favor of coverage.  For a particular
483
product received by a particular user, "normally used" refers to a
484
typical or common use of that class of product, regardless of the status
485
of the particular user or of the way in which the particular user
486
actually uses, or expects or is expected to use, the product.  A product
487
is a consumer product regardless of whether the product has substantial
488
commercial, industrial or non-consumer uses, unless such uses represent
489
the only significant mode of use of the product.
490

    
491
  "Installation Information" for a User Product means any methods,
492
procedures, authorization keys, or other information required to install
493
and execute modified versions of a covered work in that User Product from
494
a modified version of its Corresponding Source.  The information must
495
suffice to ensure that the continued functioning of the modified object
496
code is in no case prevented or interfered with solely because
497
modification has been made.
498

    
499
  If you convey an object code work under this section in, or with, or
500
specifically for use in, a User Product, and the conveying occurs as
501
part of a transaction in which the right of possession and use of the
502
User Product is transferred to the recipient in perpetuity or for a
503
fixed term (regardless of how the transaction is characterized), the
504
Corresponding Source conveyed under this section must be accompanied
505
by the Installation Information.  But this requirement does not apply
506
if neither you nor any third party retains the ability to install
507
modified object code on the User Product (for example, the work has
508
been installed in ROM).
509

    
510
  The requirement to provide Installation Information does not include a
511
requirement to continue to provide support service, warranty, or updates
512
for a work that has been modified or installed by the recipient, or for
513
the User Product in which it has been modified or installed.  Access to a
514
network may be denied when the modification itself materially and
515
adversely affects the operation of the network or violates the rules and
516
protocols for communication across the network.
517

    
518
  Corresponding Source conveyed, and Installation Information provided,
519
in accord with this section must be in a format that is publicly
520
documented (and with an implementation available to the public in
521
source code form), and must require no special password or key for
522
unpacking, reading or copying.
523

    
524
  7. Additional Terms.
525

    
526
  "Additional permissions" are terms that supplement the terms of this
527
License by making exceptions from one or more of its conditions.
528
Additional permissions that are applicable to the entire Program shall
529
be treated as though they were included in this License, to the extent
530
that they are valid under applicable law.  If additional permissions
531
apply only to part of the Program, that part may be used separately
532
under those permissions, but the entire Program remains governed by
533
this License without regard to the additional permissions.
534

    
535
  When you convey a copy of a covered work, you may at your option
536
remove any additional permissions from that copy, or from any part of
537
it.  (Additional permissions may be written to require their own
538
removal in certain cases when you modify the work.)  You may place
539
additional permissions on material, added by you to a covered work,
540
for which you have or can give appropriate copyright permission.
541

    
542
  Notwithstanding any other provision of this License, for material you
543
add to a covered work, you may (if authorized by the copyright holders of
544
that material) supplement the terms of this License with terms:
545

    
546
    a) Disclaiming warranty or limiting liability differently from the
547
    terms of sections 15 and 16 of this License; or
548

    
549
    b) Requiring preservation of specified reasonable legal notices or
550
    author attributions in that material or in the Appropriate Legal
551
    Notices displayed by works containing it; or
552

    
553
    c) Prohibiting misrepresentation of the origin of that material, or
554
    requiring that modified versions of such material be marked in
555
    reasonable ways as different from the original version; or
556

    
557
    d) Limiting the use for publicity purposes of names of licensors or
558
    authors of the material; or
559

    
560
    e) Declining to grant rights under trademark law for use of some
561
    trade names, trademarks, or service marks; or
562

    
563
    f) Requiring indemnification of licensors and authors of that
564
    material by anyone who conveys the material (or modified versions of
565
    it) with contractual assumptions of liability to the recipient, for
566
    any liability that these contractual assumptions directly impose on
567
    those licensors and authors.
568

    
569
  All other non-permissive additional terms are considered "further
570
restrictions" within the meaning of section 10.  If the Program as you
571
received it, or any part of it, contains a notice stating that it is
572
governed by this License along with a term that is a further
573
restriction, you may remove that term.  If a license document contains
574
a further restriction but permits relicensing or conveying under this
575
License, you may add to a covered work material governed by the terms
576
of that license document, provided that the further restriction does
577
not survive such relicensing or conveying.
578

    
579
  If you add terms to a covered work in accord with this section, you
580
must place, in the relevant source files, a statement of the
581
additional terms that apply to those files, or a notice indicating
582
where to find the applicable terms.
583

    
584
  Additional terms, permissive or non-permissive, may be stated in the
585
form of a separately written license, or stated as exceptions;
586
the above requirements apply either way.
587

    
588
  8. Termination.
589

    
590
  You may not propagate or modify a covered work except as expressly
591
provided under this License.  Any attempt otherwise to propagate or
592
modify it is void, and will automatically terminate your rights under
593
this License (including any patent licenses granted under the third
594
paragraph of section 11).
595

    
596
  However, if you cease all violation of this License, then your
597
license from a particular copyright holder is reinstated (a)
598
provisionally, unless and until the copyright holder explicitly and
599
finally terminates your license, and (b) permanently, if the copyright
600
holder fails to notify you of the violation by some reasonable means
601
prior to 60 days after the cessation.
602

    
603
  Moreover, your license from a particular copyright holder is
604
reinstated permanently if the copyright holder notifies you of the
605
violation by some reasonable means, this is the first time you have
606
received notice of violation of this License (for any work) from that
607
copyright holder, and you cure the violation prior to 30 days after
608
your receipt of the notice.
609

    
610
  Termination of your rights under this section does not terminate the
611
licenses of parties who have received copies or rights from you under
612
this License.  If your rights have been terminated and not permanently
613
reinstated, you do not qualify to receive new licenses for the same
614
material under section 10.
615

    
616
  9. Acceptance Not Required for Having Copies.
617

    
618
  You are not required to accept this License in order to receive or
619
run a copy of the Program.  Ancillary propagation of a covered work
620
occurring solely as a consequence of using peer-to-peer transmission
621
to receive a copy likewise does not require acceptance.  However,
622
nothing other than this License grants you permission to propagate or
623
modify any covered work.  These actions infringe copyright if you do
624
not accept this License.  Therefore, by modifying or propagating a
625
covered work, you indicate your acceptance of this License to do so.
626

    
627
  10. Automatic Licensing of Downstream Recipients.
628

    
629
  Each time you convey a covered work, the recipient automatically
630
receives a license from the original licensors, to run, modify and
631
propagate that work, subject to this License.  You are not responsible
632
for enforcing compliance by third parties with this License.
633

    
634
  An "entity transaction" is a transaction transferring control of an
635
organization, or substantially all assets of one, or subdividing an
636
organization, or merging organizations.  If propagation of a covered
637
work results from an entity transaction, each party to that
638
transaction who receives a copy of the work also receives whatever
639
licenses to the work the party's predecessor in interest had or could
640
give under the previous paragraph, plus a right to possession of the
641
Corresponding Source of the work from the predecessor in interest, if
642
the predecessor has it or can get it with reasonable efforts.
643

    
644
  You may not impose any further restrictions on the exercise of the
645
rights granted or affirmed under this License.  For example, you may
646
not impose a license fee, royalty, or other charge for exercise of
647
rights granted under this License, and you may not initiate litigation
648
(including a cross-claim or counterclaim in a lawsuit) alleging that
649
any patent claim is infringed by making, using, selling, offering for
650
sale, or importing the Program or any portion of it.
651

    
652
  11. Patents.
653

    
654
  A "contributor" is a copyright holder who authorizes use under this
655
License of the Program or a work on which the Program is based.  The
656
work thus licensed is called the contributor's "contributor version".
657

    
658
  A contributor's "essential patent claims" are all patent claims
659
owned or controlled by the contributor, whether already acquired or
660
hereafter acquired, that would be infringed by some manner, permitted
661
by this License, of making, using, or selling its contributor version,
662
but do not include claims that would be infringed only as a
663
consequence of further modification of the contributor version.  For
664
purposes of this definition, "control" includes the right to grant
665
patent sublicenses in a manner consistent with the requirements of
666
this License.
667

    
668
  Each contributor grants you a non-exclusive, worldwide, royalty-free
669
patent license under the contributor's essential patent claims, to
670
make, use, sell, offer for sale, import and otherwise run, modify and
671
propagate the contents of its contributor version.
672

    
673
  In the following three paragraphs, a "patent license" is any express
674
agreement or commitment, however denominated, not to enforce a patent
675
(such as an express permission to practice a patent or covenant not to
676
sue for patent infringement).  To "grant" such a patent license to a
677
party means to make such an agreement or commitment not to enforce a
678
patent against the party.
679

    
680
  If you convey a covered work, knowingly relying on a patent license,
681
and the Corresponding Source of the work is not available for anyone
682
to copy, free of charge and under the terms of this License, through a
683
publicly available network server or other readily accessible means,
684
then you must either (1) cause the Corresponding Source to be so
685
available, or (2) arrange to deprive yourself of the benefit of the
686
patent license for this particular work, or (3) arrange, in a manner
687
consistent with the requirements of this License, to extend the patent
688
license to downstream recipients.  "Knowingly relying" means you have
689
actual knowledge that, but for the patent license, your conveying the
690
covered work in a country, or your recipient's use of the covered work
691
in a country, would infringe one or more identifiable patents in that
692
country that you have reason to believe are valid.
693

    
694
  If, pursuant to or in connection with a single transaction or
695
arrangement, you convey, or propagate by procuring conveyance of, a
696
covered work, and grant a patent license to some of the parties
697
receiving the covered work authorizing them to use, propagate, modify
698
or convey a specific copy of the covered work, then the patent license
699
you grant is automatically extended to all recipients of the covered
700
work and works based on it.
701

    
702
  A patent license is "discriminatory" if it does not include within
703
the scope of its coverage, prohibits the exercise of, or is
704
conditioned on the non-exercise of one or more of the rights that are
705
specifically granted under this License.  You may not convey a covered
706
work if you are a party to an arrangement with a third party that is
707
in the business of distributing software, under which you make payment
708
to the third party based on the extent of your activity of conveying
709
the work, and under which the third party grants, to any of the
710
parties who would receive the covered work from you, a discriminatory
711
patent license (a) in connection with copies of the covered work
712
conveyed by you (or copies made from those copies), or (b) primarily
713
for and in connection with specific products or compilations that
714
contain the covered work, unless you entered into that arrangement,
715
or that patent license was granted, prior to 28 March 2007.
716

    
717
  Nothing in this License shall be construed as excluding or limiting
718
any implied license or other defenses to infringement that may
719
otherwise be available to you under applicable patent law.
720

    
721
  12. No Surrender of Others' Freedom.
722

    
723
  If conditions are imposed on you (whether by court order, agreement or
724
otherwise) that contradict the conditions of this License, they do not
725
excuse you from the conditions of this License.  If you cannot convey a
726
covered work so as to satisfy simultaneously your obligations under this
727
License and any other pertinent obligations, then as a consequence you may
728
not convey it at all.  For example, if you agree to terms that obligate you
729
to collect a royalty for further conveying from those to whom you convey
730
the Program, the only way you could satisfy both those terms and this
731
License would be to refrain entirely from conveying the Program.
732

    
733
  13. Use with the GNU Affero General Public License.
734

    
735
  Notwithstanding any other provision of this License, you have
736
permission to link or combine any covered work with a work licensed
737
under version 3 of the GNU Affero General Public License into a single
738
combined work, and to convey the resulting work.  The terms of this
739
License will continue to apply to the part which is the covered work,
740
but the special requirements of the GNU Affero General Public License,
741
section 13, concerning interaction through a network will apply to the
742
combination as such.
743

    
744
  14. Revised Versions of this License.
745

    
746
  The Free Software Foundation may publish revised and/or new versions of
747
the GNU General Public License from time to time.  Such new versions will
748
be similar in spirit to the present version, but may differ in detail to
749
address new problems or concerns.
750

    
751
  Each version is given a distinguishing version number.  If the
752
Program specifies that a certain numbered version of the GNU General
753
Public License "or any later version" applies to it, you have the
754
option of following the terms and conditions either of that numbered
755
version or of any later version published by the Free Software
756
Foundation.  If the Program does not specify a version number of the
757
GNU General Public License, you may choose any version ever published
758
by the Free Software Foundation.
759

    
760
  If the Program specifies that a proxy can decide which future
761
versions of the GNU General Public License can be used, that proxy's
762
public statement of acceptance of a version permanently authorizes you
763
to choose that version for the Program.
764

    
765
  Later license versions may give you additional or different
766
permissions.  However, no additional obligations are imposed on any
767
author or copyright holder as a result of your choosing to follow a
768
later version.
769

    
770
  15. Disclaimer of Warranty.
771

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

    
781
  16. Limitation of Liability.
782

    
783
  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
784
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
785
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
786
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
787
USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
788
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
789
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
790
EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
791
SUCH DAMAGES.
792

    
793
  17. Interpretation of Sections 15 and 16.
794

    
795
  If the disclaimer of warranty and limitation of liability provided
796
above cannot be given local legal effect according to their terms,
797
reviewing courts shall apply local law that most closely approximates
798
an absolute waiver of all civil liability in connection with the
799
Program, unless a warranty or assumption of liability accompanies a
800
copy of the Program in return for a fee.
801

    
802
                     END OF TERMS AND CONDITIONS
803

    
804
            How to Apply These Terms to Your New Programs
805

    
806
  If you develop a new program, and you want it to be of the greatest
807
possible use to the public, the best way to achieve this is to make it
808
free software which everyone can redistribute and change under these terms.
809

    
810
  To do so, attach the following notices to the program.  It is safest
811
to attach them to the start of each source file to most effectively
812
state the exclusion of warranty; and each file should have at least
813
the "copyright" line and a pointer to where the full notice is found.
814

    
815
    <one line to give the program's name and a brief idea of what it does.>
816
    Copyright (C) <year>  <name of author>
817

    
818
    This program is free software: you can redistribute it and/or modify
819
    it under the terms of the GNU General Public License as published by
820
    the Free Software Foundation, either version 3 of the License, or
821
    (at your option) any later version.
822

    
823
    This program is distributed in the hope that it will be useful,
824
    but WITHOUT ANY WARRANTY; without even the implied warranty of
825
    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
826
    GNU General Public License for more details.
827

    
828
    You should have received a copy of the GNU General Public License
829
    along with this program.  If not, see <http://www.gnu.org/licenses/>.
830

    
831
Also add information on how to contact you by electronic and paper mail.
832

    
833
  If the program does terminal interaction, make it output a short
834
notice like this when it starts in an interactive mode:
835

    
836
    <program>  Copyright (C) <year>  <name of author>
837
    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
838
    This is free software, and you are welcome to redistribute it
839
    under certain conditions; type `show c' for details.
840

    
841
The hypothetical commands `show w' and `show c' should show the appropriate
842
parts of the General Public License.  Of course, your program's commands
843
might be different; for a GUI interface, you would use an "about box".
844

    
845
  You should also get your employer (if you work as a programmer) or school,
846
if any, to sign a "copyright disclaimer" for the program, if necessary.
847
For more information on this, and how to apply and follow the GNU GPL, see
848
<http://www.gnu.org/licenses/>.
849

    
850
  The GNU General Public License does not permit incorporating your program
851
into proprietary programs.  If your program is a subroutine library, you
852
may consider it more useful to permit linking proprietary applications with
853
the library.  If this is what you want to do, use the GNU Lesser General
854
Public License instead of this License.  But first, please read
855
<http://www.gnu.org/philosophy/why-not-lgpl.html>.
