40 45of others.
41 For example, if you distribute copies of such a program, whether 46

43you have. You must make sure that they, too, receive or can get the 48gratis or for a fee, you must pass on to the recipients the same

45rights. 50receive or can get the source code. And you must show them these
46 51terms so they know their rights.
47 We protect your rights with two steps: (1) copyright the software, and 52
48(2) offer you this license which gives you legal permission to copy, 53Developers that use the GNU GPL protect your rights with two steps:
49distribute and/or modify the software. 54(1) assert copyright on the software, and (2) offer you this License
50 55giving you legal permission to copy, distribute and/or modify it.
51 Also, for each author's protection and ours, we want to make certain 56
52that everyone understands that there is no warranty for this free 57For the developers' and authors' protection, the GPL clearly explains
53software. If the software is modified by someone else and passed on, we 58that there is no warranty for this free software. For both users' and
54want its recipients to know that what they have is not the original, so 59authors' sake, the GPL requires that modified versions be marked as
55that any problems introduced by others will not reflect on the original 60changed, so that their problems will not be attributed erroneously to
56authors' reputations. 61authors of previous versions.
57 62
58 Finally, any free program is threatened constantly by software 63Some devices are designed to deny users access to install or run
59patents. We wish to avoid the danger that redistributors of a free 64modified versions of the software inside them, although the
60program will individually obtain patent licenses, in effect making the 65manufacturer can do so. This is fundamentally incompatible with the
61program proprietary. To prevent this, we have made it clear that any 66aim of protecting users' freedom to change the software. The
62patent must be licensed for everyone's free use or not licensed at all. 67systematic pattern of such abuse occurs in the area of products for
63 68individuals to use, which is precisely where it is most unacceptable.
64 The precise terms and conditions for copying, distribution and 69Therefore, we have designed this version of the GPL to prohibit the
70practice for those products. If such problems arise substantially in
71other domains, we stand ready to extend this provision to those
72domains in future versions of the GPL, as needed to protect the
73freedom of users.
74
75Finally, every program is threatened constantly by software patents.
76States should not allow patents to restrict development and use of
77software on general-purpose computers, but in those that do, we wish
78to avoid the special danger that patents applied to a free program
79could make it effectively proprietary. To prevent this, the GPL
80assures that patents cannot be used to render the program non-free.

76This License applies to any program or other work which contains 89
77a notice placed by the copyright holder saying it may be distributed 90``This License'' refers to version 3 of the GNU General Public License.
78under the terms of this General Public License. The ``Program'', below, 91
79refers to any such program or work, and a ``work based on the Program'' 92``Copyright'' also means copyright-like laws that apply to other kinds
80means either the Program or any derivative work under copyright law: 93of works, such as semiconductor masks.
81that is to say, a work containing the Program or a portion of it, 94
82either verbatim or with modifications and/or translated into another 95``The Program'' refers to any copyrightable work licensed under this
83language. (Hereinafter, translation is included without limitation in 96License. Each licensee is addressed as ``you''. ``Licensees'' and
84the term ``modification''.) Each licensee is addressed as ``you''. 97``recipients'' may be individuals or organizations.
85 98
86Activities other than copying, distribution and modification are not 99To ``modify'' a work means to copy from or adapt all or part of the work
87covered by this License; they are outside its scope. The act of 100in a fashion requiring copyright permission, other than the making of
88running the Program is not restricted, and the output from the Program 101an exact copy. The resulting work is called a ``modified version'' of
89is covered only if its contents constitute a work based on the 102the earlier work or a work ``based on'' the earlier work.
90Program (independent of having been made by running the Program). 103
91Whether that is true depends on what the Program does. 104A ``covered work'' means either the unmodified Program or a work based
105on the Program.
106
107To ``propagate'' a work means to do anything with it that, without
108permission, would make you directly or secondarily liable for
109infringement under applicable copyright law, except executing it on a
110computer or modifying a private copy. Propagation includes copying,
111distribution (with or without modification), making available to the
112public, and in some countries other activities as well.
113
114To ``convey'' a work means any kind of propagation that enables other
115parties to make or receive copies. Mere interaction with a user
116through a computer network, with no transfer of a copy, is not
117conveying.
118
119An interactive user interface displays ``Appropriate Legal Notices'' to
120the extent that it includes a convenient and prominently visible
121feature that (1) displays an appropriate copyright notice, and (2)
122tells the user that there is no warranty for the work (except to the
123extent that warranties are provided), that licensees may convey the
124work under this License, and how to view a copy of this License. If
125the interface presents a list of user commands or options, such as a
126menu, a prominent item in the list meets this criterion.
127
128@item Source Code.
129
130The ``source code'' for a work means the preferred form of the work for
131making modifications to it. ``Object code'' means any non-source form
132of a work.
133
134A ``Standard Interface'' means an interface that either is an official
135standard defined by a recognized standards body, or, in the case of
136interfaces specified for a particular programming language, one that
137is widely used among developers working in that language.
138
139The ``System Libraries'' of an executable work include anything, other
140than the work as a whole, that (a) is included in the normal form of
141packaging a Major Component, but which is not part of that Major
142Component, and (b) serves only to enable use of the work with that
143Major Component, or to implement a Standard Interface for which an
144implementation is available to the public in source code form. A
145``Major Component'', in this context, means a major essential component
146(kernel, window system, and so on) of the specific operating system
147(if any) on which the executable work runs, or a compiler used to
148produce the work, or an object code interpreter used to run it.
149
150The ``Corresponding Source'' for a work in object code form means all
151the source code needed to generate, install, and (for an executable
152work) run the object code and to modify the work, including scripts to
153control those activities. However, it does not include the work's
154System Libraries, or general-purpose tools or generally available free
155programs which are used unmodified in performing those activities but
156which are not part of the work. For example, Corresponding Source
157includes interface definition files associated with source files for
158the work, and the source code for shared libraries and dynamically
159linked subprograms that the work is specifically designed to require,
160such as by intimate data communication or control flow between those
161subprograms and other parts of the work.
162
163The Corresponding Source need not include anything that users can
164regenerate automatically from other parts of the Corresponding Source.
165
166The Corresponding Source for a work in source code form is that same
167work.
168
169@item Basic Permissions.
170
171All rights granted under this License are granted for the term of
172copyright on the Program, and are irrevocable provided the stated
173conditions are met. This License explicitly affirms your unlimited
174permission to run the unmodified Program. The output from running a
175covered work is covered by this License only if the output, given its
176content, constitutes a covered work. This License acknowledges your
177rights of fair use or other equivalent, as provided by copyright law.
178
179You may make, run and propagate covered works that you do not convey,
180without conditions so long as your license otherwise remains in force.
181You may convey covered works to others for the sole purpose of having
182them make modifications exclusively for you, or provide you with
183facilities for running those works, provided that you comply with the
184terms of this License in conveying all material for which you do not
185control copyright. Those thus making or running the covered works for
186you must do so exclusively on your behalf, under your direction and
187control, on terms that prohibit them from making any copies of your
188copyrighted material outside their relationship with you.
189
190Conveying under any other circumstances is permitted solely under the
191conditions stated below. Sublicensing is not allowed; section 10
192makes it unnecessary.
193
194@item Protecting Users' Legal Rights From Anti-Circumvention Law.
195
196No covered work shall be deemed part of an effective technological
197measure under any applicable law fulfilling obligations under article
19811 of the WIPO copyright treaty adopted on 20 December 1996, or
199similar laws prohibiting or restricting circumvention of such
200measures.
201
202When you convey a covered work, you waive any legal power to forbid
203circumvention of technological measures to the extent such
204circumvention is effected by exercising rights under this License with
205respect to the covered work, and you disclaim any intention to limit
206operation or modification of the work as a means of enforcing, against
207the work's users, your or third parties' legal rights to forbid
208circumvention of technological measures.
209
210@item Conveying Verbatim Copies.
211
212You may convey verbatim copies of the Program's source code as you
213receive it, in any medium, provided that you conspicuously and
214appropriately publish on each copy an appropriate copyright notice;
215keep intact all notices stating that this License and any
216non-permissive terms added in accord with section 7 apply to the code;
217keep intact all notices of the absence of any warranty; and give all
218recipients a copy of this License along with the Program.
219
220You may charge any price or no price for each copy that you convey,
221and you may offer support or warranty protection for a fee.
222
223@item Conveying Modified Source Versions.
224
225You may convey a work based on the Program, or the modifications to
226produce it from the Program, in the form of source code under the
227terms of section 4, provided that you also meet all of these
228conditions:

245to the whole of the work, and all its parts, regardless of how they
246are packaged. This License gives no permission to license the work in
247any other way, but it does not invalidate such permission if you have
248separately received it.

262used to limit the access or legal rights of the compilation's users

322A separable portion of the object code, whose source code is excluded
323from the Corresponding Source as a System Library, need not be
324included in conveying the object code work.
325
326A ``User Product'' is either (1) a ``consumer product'', which means any
327tangible personal property which is normally used for personal,
328family, or household purposes, or (2) anything designed or sold for
329incorporation into a dwelling. In determining whether a product is a
330consumer product, doubtful cases shall be resolved in favor of
331coverage. For a particular product received by a particular user,
332``normally used'' refers to a typical or common use of that class of
333product, regardless of the status of the particular user or of the way
334in which the particular user actually uses, or expects or is expected
335to use, the product. A product is a consumer product regardless of
336whether the product has substantial commercial, industrial or
337non-consumer uses, unless such uses represent the only significant
338mode of use of the product.
339
340``Installation Information'' for a User Product means any methods,
341procedures, authorization keys, or other information required to
342install and execute modified versions of a covered work in that User
343Product from a modified version of its Corresponding Source. The
344information must suffice to ensure that the continued functioning of
345the modified object code is in no case prevented or interfered with
346solely because modification has been made.
347
348If you convey an object code work under this section in, or with, or
349specifically for use in, a User Product, and the conveying occurs as
350part of a transaction in which the right of possession and use of the
351User Product is transferred to the recipient in perpetuity or for a
352fixed term (regardless of how the transaction is characterized), the
353Corresponding Source conveyed under this section must be accompanied
354by the Installation Information. But this requirement does not apply
355if neither you nor any third party retains the ability to install
356modified object code on the User Product (for example, the work has
357been installed in ROM).
358
359The requirement to provide Installation Information does not include a
360requirement to continue to provide support service, warranty, or
361updates for a work that has been modified or installed by the
362recipient, or for the User Product in which it has been modified or
363installed. Access to a network may be denied when the modification
364itself materially and adversely affects the operation of the network
365or violates the rules and protocols for communication across the
366network.
367
368Corresponding Source conveyed, and Installation Information provided,
369in accord with this section must be in a format that is publicly
370documented (and with an implementation available to the public in
371source code form), and must require no special password or key for
372unpacking, reading or copying.

374@item Additional Terms.
375
376``Additional permissions'' are terms that supplement the terms of this
377License by making exceptions from one or more of its conditions.
378Additional permissions that are applicable to the entire Program shall
379be treated as though they were included in this License, to the extent
380that they are valid under applicable law. If additional permissions
381apply only to part of the Program, that part may be used separately
382under those permissions, but the entire Program remains governed by
383this License without regard to the additional permissions.
384
385When you convey a copy of a covered work, you may at your option
386remove any additional permissions from that copy, or from any part of
387it. (Additional permissions may be written to require their own
388removal in certain cases when you modify the work.) You may place
389additional permissions on material, added by you to a covered work,
390for which you have or can give appropriate copyright permission.
391
392Notwithstanding any other provision of this License, for material you
393add to a covered work, you may (if authorized by the copyright holders
394of that material) supplement the terms of this License with terms:

181
182The source code for a work means the preferred form of the work for
183making modifications to it. For an executable work, complete source
184code means all the source code for all modules it contains, plus any
185associated interface definition files, plus the scripts used to
186control compilation and installation of the executable. However, as a
187special exception, the source code distributed need not include
188anything that is normally distributed (in either source or binary
189form) with the major components (compiler, kernel, and so on) of the
190operating system on which the executable runs, unless that component
191itself accompanies the executable.
192
193If distribution of executable or object code is made by offering
194access to copy from a designated place, then offering equivalent
195access to copy the source code from the same place counts as
196distribution of the source code, even though third parties are not
197compelled to copy the source along with the object code.

200You may not copy, modify, sublicense, or distribute the Program 412Limiting the use for publicity purposes of names of licensors or
201except as expressly provided under this License. Any attempt 413authors of the material; or
202otherwise to copy, modify, sublicense or distribute the Program is
203void, and will automatically terminate your rights under this License.
204However, parties who have received copies, or rights, from you under
205this License will not have their licenses terminated so long as such
206parties remain in full compliance.

208@item 415@item
209You are not required to accept this License, since you have not 416Declining to grant rights under trademark law for use of some trade

211distribute the Program or its derivative works. These actions are
212prohibited by law if you do not accept this License. Therefore, by
213modifying or distributing the Program (or any work based on the
214Program), you indicate your acceptance of this License to do so, and
215all its terms and conditions for copying, distributing or modifying
216the Program or works based on it.

219Each time you redistribute the Program (or any work based on the 420Requiring indemnification of licensors and authors of that material by
220Program), the recipient automatically receives a license from the 421anyone who conveys the material (or modified versions of it) with
221original licensor to copy, distribute or modify the Program subject to 422contractual assumptions of liability to the recipient, for any
222these terms and conditions. You may not impose any further 423liability that these contractual assumptions directly impose on those
223restrictions on the recipients' exercise of the rights granted herein. 424licensors and authors.
224You are not responsible for enforcing compliance by third parties to 425@end enumerate
426
427All other non-permissive additional terms are considered ``further
428restrictions'' within the meaning of section 10. If the Program as you
429received it, or any part of it, contains a notice stating that it is
430governed by this License along with a term that is a further
431restriction, you may remove that term. If a license document contains
432a further restriction but permits relicensing or conveying under this
433License, you may add to a covered work material governed by the terms
434of that license document, provided that the further restriction does
435not survive such relicensing or conveying.
436
437If you add terms to a covered work in accord with this section, you
438must place, in the relevant source files, a statement of the
439additional terms that apply to those files, or a notice indicating
440where to find the applicable terms.
441
442Additional terms, permissive or non-permissive, may be stated in the
443form of a separately written license, or stated as exceptions; the
444above requirements apply either way.
445
446@item Termination.
447
448You may not propagate or modify a covered work except as expressly
449provided under this License. Any attempt otherwise to propagate or
450modify it is void, and will automatically terminate your rights under
451this License (including any patent licenses granted under the third
452paragraph of section 11).
453
454However, if you cease all violation of this License, then your license
455from a particular copyright holder is reinstated (a) provisionally,
456unless and until the copyright holder explicitly and finally
457terminates your license, and (b) permanently, if the copyright holder
458fails to notify you of the violation by some reasonable means prior to
45960 days after the cessation.
460
461Moreover, your license from a particular copyright holder is
462reinstated permanently if the copyright holder notifies you of the
463violation by some reasonable means, this is the first time you have
464received notice of violation of this License (for any work) from that
465copyright holder, and you cure the violation prior to 30 days after
466your receipt of the notice.
467
468Termination of your rights under this section does not terminate the
469licenses of parties who have received copies or rights from you under
470this License. If your rights have been terminated and not permanently
471reinstated, you do not qualify to receive new licenses for the same
472material under section 10.
473
474@item Acceptance Not Required for Having Copies.
475
476You are not required to accept this License in order to receive or run
477a copy of the Program. Ancillary propagation of a covered work
478occurring solely as a consequence of using peer-to-peer transmission
479to receive a copy likewise does not require acceptance. However,
480nothing other than this License grants you permission to propagate or
481modify any covered work. These actions infringe copyright if you do
482not accept this License. Therefore, by modifying or propagating a
483covered work, you indicate your acceptance of this License to do so.
484
485@item Automatic Licensing of Downstream Recipients.
486
487Each time you convey a covered work, the recipient automatically
488receives a license from the original licensors, to run, modify and
489propagate that work, subject to this License. You are not responsible
490for enforcing compliance by third parties with this License.
491
492An ``entity transaction'' is a transaction transferring control of an
493organization, or substantially all assets of one, or subdividing an
494organization, or merging organizations. If propagation of a covered
495work results from an entity transaction, each party to that
496transaction who receives a copy of the work also receives whatever
497licenses to the work the party's predecessor in interest had or could
498give under the previous paragraph, plus a right to possession of the
499Corresponding Source of the work from the predecessor in interest, if
500the predecessor has it or can get it with reasonable efforts.
501
502You may not impose any further restrictions on the exercise of the
503rights granted or affirmed under this License. For example, you may
504not impose a license fee, royalty, or other charge for exercise of
505rights granted under this License, and you may not initiate litigation
506(including a cross-claim or counterclaim in a lawsuit) alleging that
507any patent claim is infringed by making, using, selling, offering for
508sale, or importing the Program or any portion of it.
509
510@item Patents.
511
512A ``contributor'' is a copyright holder who authorizes use under this
513License of the Program or a work on which the Program is based. The
514work thus licensed is called the contributor's ``contributor version''.
515
516A contributor's ``essential patent claims'' are all patent claims owned
517or controlled by the contributor, whether already acquired or
518hereafter acquired, that would be infringed by some manner, permitted
519by this License, of making, using, or selling its contributor version,
520but do not include claims that would be infringed only as a
521consequence of further modification of the contributor version. For
522purposes of this definition, ``control'' includes the right to grant
523patent sublicenses in a manner consistent with the requirements of
225this License. 524this License.

531In the following three paragraphs, a ``patent license'' is any express
532agreement or commitment, however denominated, not to enforce a patent
533(such as an express permission to practice a patent or covenant not to
534sue for patent infringement). To ``grant'' such a patent license to a
535party means to make such an agreement or commitment not to enforce a
536patent against the party.
537
538If you convey a covered work, knowingly relying on a patent license,
539and the Corresponding Source of the work is not available for anyone
540to copy, free of charge and under the terms of this License, through a
541publicly available network server or other readily accessible means,
542then you must either (1) cause the Corresponding Source to be so
543available, or (2) arrange to deprive yourself of the benefit of the
544patent license for this particular work, or (3) arrange, in a manner
545consistent with the requirements of this License, to extend the patent
546license to downstream recipients. ``Knowingly relying'' means you have
547actual knowledge that, but for the patent license, your conveying the
548covered work in a country, or your recipient's use of the covered work
549in a country, would infringe one or more identifiable patents in that
550country that you have reason to believe are valid.
551
552If, pursuant to or in connection with a single transaction or
553arrangement, you convey, or propagate by procuring conveyance of, a
554covered work, and grant a patent license to some of the parties
555receiving the covered work authorizing them to use, propagate, modify
556or convey a specific copy of the covered work, then the patent license
557you grant is automatically extended to all recipients of the covered
558work and works based on it.
559
560A patent license is ``discriminatory'' if it does not include within the
561scope of its coverage, prohibits the exercise of, or is conditioned on
562the non-exercise of one or more of the rights that are specifically
563granted under this License. You may not convey a covered work if you
564are a party to an arrangement with a third party that is in the
565business of distributing software, under which you make payment to the
566third party based on the extent of your activity of conveying the
567work, and under which the third party grants, to any of the parties
568who would receive the covered work from you, a discriminatory patent
569license (a) in connection with copies of the covered work conveyed by
570you (or copies made from those copies), or (b) primarily for and in
571connection with specific products or compilations that contain the
572covered work, unless you entered into that arrangement, or that patent
573license was granted, prior to 28 March 2007.
574
575Nothing in this License shall be construed as excluding or limiting
576any implied license or other defenses to infringement that may
577otherwise be available to you under applicable patent law.
