31@heading Preamble
32
33The GNU General Public License is a free, copyleft license for
34software and other kinds of works.
5796c8dc 35
cf7f2e2d
JM
36The licenses for most software and other practical works are designed
37to take away your freedom to share and change the works. By contrast,
38the GNU General Public License is intended to guarantee your freedom
39to share and change all versions of a program---to make sure it remains
40free software for all its users. We, the Free Software Foundation,
41use the GNU General Public License for most of our software; it
42applies also to any other work released this way by its authors. You
43can apply it to your programs, too.
5796c8dc 44
cf7f2e2d 45When we speak of free software, we are referring to freedom, not
5796c8dc
SS
46price. Our General Public Licenses are designed to make sure that you
47have the freedom to distribute copies of free software (and charge for
cf7f2e2d
JM
48them if you wish), that you receive source code or can get it if you
49want it, that you can change the software or use pieces of it in new
50free programs, and that you know you can do these things.
51
52To protect your rights, we need to prevent others from denying you
53these rights or asking you to surrender the rights. Therefore, you
54have certain responsibilities if you distribute copies of the
55software, or if you modify it: responsibilities to respect the freedom
56of others.
57
58For example, if you distribute copies of such a program, whether
59gratis or for a fee, you must pass on to the recipients the same
60freedoms that you received. You must make sure that they, too,
61receive or can get the source code. And you must show them these
62terms so they know their rights.
63
64Developers that use the GNU GPL protect your rights with two steps:
65(1) assert copyright on the software, and (2) offer you this License
66giving you legal permission to copy, distribute and/or modify it.
67
68For the developers' and authors' protection, the GPL clearly explains
69that there is no warranty for this free software. For both users' and
70authors' sake, the GPL requires that modified versions be marked as
71changed, so that their problems will not be attributed erroneously to
72authors of previous versions.
73
74Some devices are designed to deny users access to install or run
75modified versions of the software inside them, although the
76manufacturer can do so. This is fundamentally incompatible with the
77aim of protecting users' freedom to change the software. The
78systematic pattern of such abuse occurs in the area of products for
79individuals to use, which is precisely where it is most unacceptable.
80Therefore, we have designed this version of the GPL to prohibit the
81practice for those products. If such problems arise substantially in
82other domains, we stand ready to extend this provision to those
83domains in future versions of the GPL, as needed to protect the
84freedom of users.
85
86Finally, every program is threatened constantly by software patents.
87States should not allow patents to restrict development and use of
88software on general-purpose computers, but in those that do, we wish
89to avoid the special danger that patents applied to a free program
90could make it effectively proprietary. To prevent this, the GPL
91assures that patents cannot be used to render the program non-free.
92
93The precise terms and conditions for copying, distribution and
5796c8dc

94modification follow.

5796c8dc
SS
97
98@enumerate 0
cf7f2e2d
JM
99@item Definitions.
100
101``This License'' refers to version 3 of the GNU General Public License.
102
103``Copyright'' also means copyright-like laws that apply to other kinds
104of works, such as semiconductor masks.
105
106``The Program'' refers to any copyrightable work licensed under this
107License. Each licensee is addressed as ``you''. ``Licensees'' and
108``recipients'' may be individuals or organizations.
109
110To ``modify'' a work means to copy from or adapt all or part of the work
111in a fashion requiring copyright permission, other than the making of
112an exact copy. The resulting work is called a ``modified version'' of
113the earlier work or a work ``based on'' the earlier work.
114
115A ``covered work'' means either the unmodified Program or a work based
116on the Program.
117
118To ``propagate'' a work means to do anything with it that, without
119permission, would make you directly or secondarily liable for
120infringement under applicable copyright law, except executing it on a
121computer or modifying a private copy. Propagation includes copying,
122distribution (with or without modification), making available to the
123public, and in some countries other activities as well.
124
125To ``convey'' a work means any kind of propagation that enables other
126parties to make or receive copies. Mere interaction with a user
127through a computer network, with no transfer of a copy, is not
128conveying.
129
130An interactive user interface displays ``Appropriate Legal Notices'' to
131the extent that it includes a convenient and prominently visible
132feature that (1) displays an appropriate copyright notice, and (2)
133tells the user that there is no warranty for the work (except to the
134extent that warranties are provided), that licensees may convey the
135work under this License, and how to view a copy of this License. If
136the interface presents a list of user commands or options, such as a
137menu, a prominent item in the list meets this criterion.
138
139@item Source Code.
140
141The ``source code'' for a work means the preferred form of the work for
142making modifications to it. ``Object code'' means any non-source form
143of a work.
144
145A ``Standard Interface'' means an interface that either is an official
146standard defined by a recognized standards body, or, in the case of
147interfaces specified for a particular programming language, one that
148is widely used among developers working in that language.
149
150The ``System Libraries'' of an executable work include anything, other
151than the work as a whole, that (a) is included in the normal form of
152packaging a Major Component, but which is not part of that Major
153Component, and (b) serves only to enable use of the work with that
154Major Component, or to implement a Standard Interface for which an
155implementation is available to the public in source code form. A
156``Major Component'', in this context, means a major essential component
157(kernel, window system, and so on) of the specific operating system
158(if any) on which the executable work runs, or a compiler used to
159produce the work, or an object code interpreter used to run it.
160
161The ``Corresponding Source'' for a work in object code form means all
162the source code needed to generate, install, and (for an executable
163work) run the object code and to modify the work, including scripts to
164control those activities. However, it does not include the work's
165System Libraries, or general-purpose tools or generally available free
166programs which are used unmodified in performing those activities but
167which are not part of the work. For example, Corresponding Source
168includes interface definition files associated with source files for
169the work, and the source code for shared libraries and dynamically
170linked subprograms that the work is specifically designed to require,
171such as by intimate data communication or control flow between those
172subprograms and other parts of the work.
173
174The Corresponding Source need not include anything that users can
175regenerate automatically from other parts of the Corresponding Source.
176
177The Corresponding Source for a work in source code form is that same
178work.
179
180@item Basic Permissions.
181
182All rights granted under this License are granted for the term of
183copyright on the Program, and are irrevocable provided the stated
184conditions are met. This License explicitly affirms your unlimited
185permission to run the unmodified Program. The output from running a
186covered work is covered by this License only if the output, given its
187content, constitutes a covered work. This License acknowledges your
188rights of fair use or other equivalent, as provided by copyright law.
189
190You may make, run and propagate covered works that you do not convey,
191without conditions so long as your license otherwise remains in force.
192You may convey covered works to others for the sole purpose of having
193them make modifications exclusively for you, or provide you with
194facilities for running those works, provided that you comply with the
195terms of this License in conveying all material for which you do not
196control copyright. Those thus making or running the covered works for
197you must do so exclusively on your behalf, under your direction and
198control, on terms that prohibit them from making any copies of your
199copyrighted material outside their relationship with you.
200
201Conveying under any other circumstances is permitted solely under the
202conditions stated below. Sublicensing is not allowed; section 10
203makes it unnecessary.
204
205@item Protecting Users' Legal Rights From Anti-Circumvention Law.
206
207No covered work shall be deemed part of an effective technological
208measure under any applicable law fulfilling obligations under article
20911 of the WIPO copyright treaty adopted on 20 December 1996, or
210similar laws prohibiting or restricting circumvention of such
211measures.
212
213When you convey a covered work, you waive any legal power to forbid
214circumvention of technological measures to the extent such
215circumvention is effected by exercising rights under this License with
216respect to the covered work, and you disclaim any intention to limit
217operation or modification of the work as a means of enforcing, against
218the work's users, your or third parties' legal rights to forbid
219circumvention of technological measures.
220
221@item Conveying Verbatim Copies.
222
223You may convey verbatim copies of the Program's source code as you
224receive it, in any medium, provided that you conspicuously and
225appropriately publish on each copy an appropriate copyright notice;
226keep intact all notices stating that this License and any
227non-permissive terms added in accord with section 7 apply to the code;
228keep intact all notices of the absence of any warranty; and give all
229recipients a copy of this License along with the Program.
230
231You may charge any price or no price for each copy that you convey,
232and you may offer support or warranty protection for a fee.
233
234@item Conveying Modified Source Versions.
235
236You may convey a work based on the Program, or the modifications to
237produce it from the Program, in the form of source code under the
238terms of section 4, provided that you also meet all of these
239conditions:
240
241@enumerate a
5796c8dc 242@item
cf7f2e2d
JM
243The work must carry prominent notices stating that you modified it,
244and giving a relevant date.
5796c8dc
SS
245
246@item
cf7f2e2d
JM
247The work must carry prominent notices stating that it is released
248under this License and any conditions added under section 7. This
249requirement modifies the requirement in section 4 to ``keep intact all
250notices''.
5796c8dc 251
cf7f2e2d
JM
252@item
253You must license the entire work, as a whole, under this License to
254anyone who comes into possession of a copy. This License will
255therefore apply, along with any applicable section 7 additional terms,
256to the whole of the work, and all its parts, regardless of how they
257are packaged. This License gives no permission to license the work in
258any other way, but it does not invalidate such permission if you have
259separately received it.
5796c8dc
SS
260
261@item
cf7f2e2d
JM
262If the work has interactive user interfaces, each must display
263Appropriate Legal Notices; however, if the Program has interactive
264interfaces that do not display Appropriate Legal Notices, your work
265need not make them do so.
266@end enumerate
267
268A compilation of a covered work with other separate and independent
269works, which are not by their nature extensions of the covered work,
270and which are not combined with it such as to form a larger program,
271in or on a volume of a storage or distribution medium, is called an
272``aggregate'' if the compilation and its resulting copyright are not
273used to limit the access or legal rights of the compilation's users
274beyond what the individual works permit. Inclusion of a covered work
275in an aggregate does not cause this License to apply to the other
276parts of the aggregate.
277
278@item Conveying Non-Source Forms.
279
280You may convey a covered work in object code form under the terms of
281sections 4 and 5, provided that you also convey the machine-readable
282Corresponding Source under the terms of this License, in one of these
283ways:
5796c8dc
SS
284
285@enumerate a
286@item
cf7f2e2d
JM
287Convey the object code in, or embodied in, a physical product
288(including a physical distribution medium), accompanied by the
289Corresponding Source fixed on a durable physical medium customarily
290used for software interchange.
5796c8dc
SS
291
292@item
cf7f2e2d
JM
293Convey the object code in, or embodied in, a physical product
294(including a physical distribution medium), accompanied by a written
295offer, valid for at least three years and valid for as long as you
296offer spare parts or customer support for that product model, to give
297anyone who possesses the object code either (1) a copy of the
298Corresponding Source for all the software in the product that is
299covered by this License, on a durable physical medium customarily used
300for software interchange, for a price no more than your reasonable
301cost of physically performing this conveying of source, or (2) access
302to copy the Corresponding Source from a network server at no charge.
5796c8dc
SS
303
304@item
cf7f2e2d
JM
305Convey individual copies of the object code with a copy of the written
306offer to provide the Corresponding Source. This alternative is
307allowed only occasionally and noncommercially, and only if you
308received the object code with such an offer, in accord with subsection
3096b.
5796c8dc 310
cf7f2e2d
JM
311@item
312Convey the object code by offering access from a designated place
313(gratis or for a charge), and offer equivalent access to the
314Corresponding Source in the same way through the same place at no
315further charge. You need not require recipients to copy the
316Corresponding Source along with the object code. If the place to copy
317the object code is a network server, the Corresponding Source may be
318on a different server (operated by you or a third party) that supports
319equivalent copying facilities, provided you maintain clear directions
320next to the object code saying where to find the Corresponding Source.
321Regardless of what server hosts the Corresponding Source, you remain
322obligated to ensure that it is available for as long as needed to
323satisfy these requirements.
5796c8dc
SS
324
325@item
cf7f2e2d
JM
326Convey the object code using peer-to-peer transmission, provided you
327inform other peers where the object code and Corresponding Source of
328the work are being offered to the general public at no charge under
329subsection 6d.
330
331@end enumerate
332
333A separable portion of the object code, whose source code is excluded
334from the Corresponding Source as a System Library, need not be
335included in conveying the object code work.
336
337A ``User Product'' is either (1) a ``consumer product'', which means any
338tangible personal property which is normally used for personal,
339family, or household purposes, or (2) anything designed or sold for
340incorporation into a dwelling. In determining whether a product is a
341consumer product, doubtful cases shall be resolved in favor of
342coverage. For a particular product received by a particular user,
343``normally used'' refers to a typical or common use of that class of
344product, regardless of the status of the particular user or of the way
345in which the particular user actually uses, or expects or is expected
346to use, the product. A product is a consumer product regardless of
347whether the product has substantial commercial, industrial or
348non-consumer uses, unless such uses represent the only significant
349mode of use of the product.
350
351``Installation Information'' for a User Product means any methods,
352procedures, authorization keys, or other information required to
353install and execute modified versions of a covered work in that User
354Product from a modified version of its Corresponding Source. The
355information must suffice to ensure that the continued functioning of
356the modified object code is in no case prevented or interfered with
357solely because modification has been made.
358
359If you convey an object code work under this section in, or with, or
360specifically for use in, a User Product, and the conveying occurs as
361part of a transaction in which the right of possession and use of the
362User Product is transferred to the recipient in perpetuity or for a
363fixed term (regardless of how the transaction is characterized), the
364Corresponding Source conveyed under this section must be accompanied
365by the Installation Information. But this requirement does not apply
366if neither you nor any third party retains the ability to install
367modified object code on the User Product (for example, the work has
368been installed in ROM).
369
370The requirement to provide Installation Information does not include a
371requirement to continue to provide support service, warranty, or
372updates for a work that has been modified or installed by the
373recipient, or for the User Product in which it has been modified or
374installed. Access to a network may be denied when the modification
375itself materially and adversely affects the operation of the network
376or violates the rules and protocols for communication across the
377network.
378
379Corresponding Source conveyed, and Installation Information provided,
380in accord with this section must be in a format that is publicly
381documented (and with an implementation available to the public in
382source code form), and must require no special password or key for
383unpacking, reading or copying.
384
385@item Additional Terms.
386
387``Additional permissions'' are terms that supplement the terms of this
388License by making exceptions from one or more of its conditions.
389Additional permissions that are applicable to the entire Program shall
390be treated as though they were included in this License, to the extent
391that they are valid under applicable law. If additional permissions
392apply only to part of the Program, that part may be used separately
393under those permissions, but the entire Program remains governed by
394this License without regard to the additional permissions.
395
396When you convey a copy of a covered work, you may at your option
397remove any additional permissions from that copy, or from any part of
398it. (Additional permissions may be written to require their own
399removal in certain cases when you modify the work.) You may place
400additional permissions on material, added by you to a covered work,
401for which you have or can give appropriate copyright permission.
402
403Notwithstanding any other provision of this License, for material you
404add to a covered work, you may (if authorized by the copyright holders
405of that material) supplement the terms of this License with terms:
5796c8dc

432anyone who conveys the material (or modified versions of it) with
433contractual assumptions of liability to the recipient, for any
434liability that these contractual assumptions directly impose on those
435licensors and authors.
436@end enumerate
437
438All other non-permissive additional terms are considered ``further
439restrictions'' within the meaning of section 10. If the Program as you
440received it, or any part of it, contains a notice stating that it is
441governed by this License along with a term that is a further
442restriction, you may remove that term. If a license document contains
443a further restriction but permits relicensing or conveying under this
444License, you may add to a covered work material governed by the terms
445of that license document, provided that the further restriction does
446not survive such relicensing or conveying.
447
448If you add terms to a covered work in accord with this section, you
449must place, in the relevant source files, a statement of the
450additional terms that apply to those files, or a notice indicating
451where to find the applicable terms.
452
453Additional terms, permissive or non-permissive, may be stated in the
454form of a separately written license, or stated as exceptions; the
455above requirements apply either way.
456
457@item Termination.
458
459You may not propagate or modify a covered work except as expressly
460provided under this License. Any attempt otherwise to propagate or
461modify it is void, and will automatically terminate your rights under
462this License (including any patent licenses granted under the third
463paragraph of section 11).
464
465However, if you cease all violation of this License, then your license
466from a particular copyright holder is reinstated (a) provisionally,
467unless and until the copyright holder explicitly and finally
468terminates your license, and (b) permanently, if the copyright holder
469fails to notify you of the violation by some reasonable means prior to
47060 days after the cessation.
471
472Moreover, your license from a particular copyright holder is
473reinstated permanently if the copyright holder notifies you of the
474violation by some reasonable means, this is the first time you have
475received notice of violation of this License (for any work) from that
476copyright holder, and you cure the violation prior to 30 days after
477your receipt of the notice.
478
479Termination of your rights under this section does not terminate the
480licenses of parties who have received copies or rights from you under
481this License. If your rights have been terminated and not permanently
482reinstated, you do not qualify to receive new licenses for the same
483material under section 10.
484
485@item Acceptance Not Required for Having Copies.
486
487You are not required to accept this License in order to receive or run
488a copy of the Program. Ancillary propagation of a covered work
489occurring solely as a consequence of using peer-to-peer transmission
490to receive a copy likewise does not require acceptance. However,
491nothing other than this License grants you permission to propagate or
492modify any covered work. These actions infringe copyright if you do
493not accept this License. Therefore, by modifying or propagating a
494covered work, you indicate your acceptance of this License to do so.
495
496@item Automatic Licensing of Downstream Recipients.
497
498Each time you convey a covered work, the recipient automatically
499receives a license from the original licensors, to run, modify and
500propagate that work, subject to this License. You are not responsible
501for enforcing compliance by third parties with this License.
502
503An ``entity transaction'' is a transaction transferring control of an
504organization, or substantially all assets of one, or subdividing an
505organization, or merging organizations. If propagation of a covered
506work results from an entity transaction, each party to that
507transaction who receives a copy of the work also receives whatever
508licenses to the work the party's predecessor in interest had or could
509give under the previous paragraph, plus a right to possession of the
510Corresponding Source of the work from the predecessor in interest, if
511the predecessor has it or can get it with reasonable efforts.
512
513You may not impose any further restrictions on the exercise of the
514rights granted or affirmed under this License. For example, you may
515not impose a license fee, royalty, or other charge for exercise of
516rights granted under this License, and you may not initiate litigation
517(including a cross-claim or counterclaim in a lawsuit) alleging that
518any patent claim is infringed by making, using, selling, offering for
519sale, or importing the Program or any portion of it.
520
521@item Patents.
522
523A ``contributor'' is a copyright holder who authorizes use under this
524License of the Program or a work on which the Program is based. The
525work thus licensed is called the contributor's ``contributor version''.
526
527A contributor's ``essential patent claims'' are all patent claims owned
528or controlled by the contributor, whether already acquired or
529hereafter acquired, that would be infringed by some manner, permitted
530by this License, of making, using, or selling its contributor version,
531but do not include claims that would be infringed only as a
532consequence of further modification of the contributor version. For
533purposes of this definition, ``control'' includes the right to grant
534patent sublicenses in a manner consistent with the requirements of
5796c8dc
SS
535this License.
536
cf7f2e2d
JM
537Each contributor grants you a non-exclusive, worldwide, royalty-free
538patent license under the contributor's essential patent claims, to
539make, use, sell, offer for sale, import and otherwise run, modify and
540propagate the contents of its contributor version.
541
542In the following three paragraphs, a ``patent license'' is any express
543agreement or commitment, however denominated, not to enforce a patent
544(such as an express permission to practice a patent or covenant not to
545sue for patent infringement). To ``grant'' such a patent license to a
546party means to make such an agreement or commitment not to enforce a
547patent against the party.
548
549If you convey a covered work, knowingly relying on a patent license,
550and the Corresponding Source of the work is not available for anyone
551to copy, free of charge and under the terms of this License, through a
552publicly available network server or other readily accessible means,
553then you must either (1) cause the Corresponding Source to be so
554available, or (2) arrange to deprive yourself of the benefit of the
555patent license for this particular work, or (3) arrange, in a manner
556consistent with the requirements of this License, to extend the patent
557license to downstream recipients. ``Knowingly relying'' means you have
558actual knowledge that, but for the patent license, your conveying the
559covered work in a country, or your recipient's use of the covered work
560in a country, would infringe one or more identifiable patents in that
561country that you have reason to believe are valid.
562
563If, pursuant to or in connection with a single transaction or
564arrangement, you convey, or propagate by procuring conveyance of, a
565covered work, and grant a patent license to some of the parties
566receiving the covered work authorizing them to use, propagate, modify
567or convey a specific copy of the covered work, then the patent license
568you grant is automatically extended to all recipients of the covered
569work and works based on it.
570
571A patent license is ``discriminatory'' if it does not include within the
572scope of its coverage, prohibits the exercise of, or is conditioned on
573the non-exercise of one or more of the rights that are specifically
574granted under this License. You may not convey a covered work if you
575are a party to an arrangement with a third party that is in the
576business of distributing software, under which you make payment to the
577third party based on the extent of your activity of conveying the
578work, and under which the third party grants, to any of the parties
579who would receive the covered work from you, a discriminatory patent
580license (a) in connection with copies of the covered work conveyed by
581you (or copies made from those copies), or (b) primarily for and in
582connection with specific products or compilations that contain the
583covered work, unless you entered into that arrangement, or that patent
584license was granted, prior to 28 March 2007.
585
586Nothing in this License shall be construed as excluding or limiting
587any implied license or other defenses to infringement that may
588otherwise be available to you under applicable patent law.
589
590@item No Surrender of Others' Freedom.
591
592If conditions are imposed on you (whether by court order, agreement or
5796c8dc 593otherwise) that contradict the conditions of this License, they do not
cf7f2e2d
JM
594excuse you from the conditions of this License. If you cannot convey
595a covered work so as to satisfy simultaneously your obligations under
596this License and any other pertinent obligations, then as a
597consequence you may not convey it at all. For example, if you agree
598to terms that obligate you to collect a royalty for further conveying
599from those to whom you convey the Program, the only way you could
600satisfy both those terms and this License would be to refrain entirely
601from conveying the Program.
602
603@item Use with the GNU Affero General Public License.
604
605Notwithstanding any other provision of this License, you have
606permission to link or combine any covered work with a work licensed
607under version 3 of the GNU Affero General Public License into a single
608combined work, and to convey the resulting work. The terms of this
609License will continue to apply to the part which is the covered work,
610but the special requirements of the GNU Affero General Public License,
611section 13, concerning interaction through a network will apply to the
612combination as such.
613
614@item Revised Versions of this License.
5796c8dc 615
5796c8dc 616The Free Software Foundation may publish revised and/or new versions
cf7f2e2d
JM
617of the GNU General Public License from time to time. Such new
618versions will be similar in spirit to the present version, but may
619differ in detail to address new problems or concerns.
5796c8dc
SS
620
621Each version is given a distinguishing version number. If the Program
cf7f2e2d
JM
622specifies that a certain numbered version of the GNU General Public
623License ``or any later version'' applies to it, you have the option of
624following the terms and conditions either of that numbered version or
625of any later version published by the Free Software Foundation. If
626the Program does not specify a version number of the GNU General
627Public License, you may choose any version ever published by the Free
628Software Foundation.
629
630If the Program specifies that a proxy can decide which future versions
631of the GNU General Public License can be used, that proxy's public
632statement of acceptance of a version permanently authorizes you to
633choose that version for the Program.
634
635Later license versions may give you additional or different
636permissions. However, no additional obligations are imposed on any
637author or copyright holder as a result of your choosing to follow a
638later version.
639
640@item Disclaimer of Warranty.
641
642THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
643APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
644HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM ``AS IS'' WITHOUT
645WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT
646LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR
647A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND
648PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE
649DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
650CORRECTION.
651
652@item Limitation of Liability.
5796c8dc 653
5796c8dc 654IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
cf7f2e2d
JM
655WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR
656CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
657INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES
658ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT
659NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR
660LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM
661TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER
662PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
663
664@item Interpretation of Sections 15 and 16.
665
666If the disclaimer of warranty and limitation of liability provided
667above cannot be given local legal effect according to their terms,
668reviewing courts shall apply local law that most closely approximates
669an absolute waiver of all civil liability in connection with the
670Program, unless a warranty or assumption of liability accompanies a
671copy of the Program in return for a fee.

cf7f2e2d 684To do so, attach the following notices to the program. It is safest
