5 "The Program" refers to any copyrightable work licensed under this
6 License. Each licensee is addressed as "you".
8 To "modify" a work means to copy from or adapt all or part of the work
9 in a fashion requiring copyright permission, other than the making of an
10 exact copy. The resulting work is called a "modified version" of the
11 earlier work or a work "based on" the earlier work.
13 A "Covered Work" means either the unmodified Program or a work based
16 To "propagate" a work means to do anything with it that, without
17 permission, would make you directly or secondarily liable for
18 infringement under applicable copyright law, except executing it on a
19 computer or modifying a private copy. Propagation includes copying,
20 distribution (with or without modification), making available to the
21 public, and in some countries other activities as well.
23 To "convey" a work means any kind of propagation that enables other
24 parties to make or receive copies. Mere interaction with a user through
25 a computer network, with no transfer of a copy, is not conveying.
27 An interactive user interface displays "Appropriate Legal Notices"
28 to the extent that it includes a convenient and prominently visible
29 feature that (1) displays an appropriate copyright notice, and (2)
30 tells the user that there is no warranty for the work (except to the
31 extent that warranties are provided), that licensees may convey the
32 work under this License, and how to view a copy of this License. If
33 the interface presents a list of user commands or options, such as a
34 menu, a prominent item in the list meets this criterion.
36 "License Steward" is left undefined for the time being.
40 The "source code" for a work means the preferred form of the work
41 for making modifications to it. "Object code" means any non-source
44 A "Standard Interface" means an interface that either is an official
45 standard defined by a recognized standards body, or, in the case of
46 interfaces specified for a particular programming language, one that
47 is widely used among developers working in that language.
49 The "System Libraries" of an executable work include anything, other
50 than the work as a whole, that (a) is included in the normal form of
51 packaging a Major Component, but which is not part of that Major
52 Component, and (b) serves only to enable use of the work with that
53 Major Component, or to implement a Standard Interface for which an
54 implementation is available to the public in source code form. A
55 "Major Component", in this context, means a major essential component
56 (kernel, window system, and so on) of the specific operating system
57 (if any) on which the executable work runs, or a compiler used to
58 produce the work, or an object code interpreter used to run it.
60 The "Corresponding Source" for a work in object code form means all
61 the source code needed to generate, install, and (for an executable
62 work) run the object code and to modify the work, including scripts to
63 control those activities. However, it does not include the work's
64 System Libraries, or general-purpose tools or generally available free
65 programs which are used unmodified in performing those activities but
66 which are not part of the work. For example, Corresponding Source
67 includes interface definition files associated with source files for
68 the work, and the source code for shared libraries and dynamically
69 linked subprograms that the work is specifically designed to require,
70 such as by intimate data communication or control flow between those
71 subprograms and other parts of the work.
75 All rights granted under this License are granted for the term of
76 copyright on the Program, and are irrevocable provided the stated
77 conditions are met. This License explicitly affirms your unlimited
78 permission to run the unmodified Program. The output from running a
79 Covered Work is covered by this License only if the output, given its
80 content, constitutes a Covered Work. This License acknowledges your
81 rights of fair use or other equivalent, as provided by copyright law.
83 You may make, run and propagate Covered Works that you do not
84 convey, without conditions so long as your license otherwise remains
85 in force. You may convey Covered Works to others for the sole purpose
86 of having them make modifications exclusively for you, or provide you
87 with facilities for running those works, provided that you comply with
88 the terms of this License in conveying all material for which you do
89 not control copyright. Those thus making or running the Covered Works
90 for you must do so exclusively on your behalf, under your direction
91 and control, on terms that prohibit them from making any copies of
92 your copyrighted material outside their relationship with you.
94 Conveying under any other circumstances is permitted solely under
95 the conditions stated below. Sublicensing is not allowed; section 10
98 3. Anti-Circumvention Law.
100 No Covered Work shall be deemed part of an effective technological
101 measure under any applicable law fulfilling obligations under article
102 11 of the WIPO copyright treaty adopted on 20 December 1996, or
103 similar laws prohibiting or restricting circumvention of such
106 When you convey a Covered Work, you waive any legal power to forbid
107 circumvention of technological measures to the extent such circumvention
108 is effected by exercising rights under this License with respect to
109 the Covered Work, and you disclaim any intention to limit operation or
110 modification of the work as a means of enforcing, against the work's
111 users, your or third parties' legal rights to forbid circumvention of
112 technological measures.
114 4. Conveying Verbatim Copies.
116 You may convey verbatim copies of the Program's source code as you
117 receive it, in any medium, provided that you conspicuously and
118 appropriately publish on each copy an appropriate copyright notice;
119 keep intact all notices stating that this License and any
120 non-permissive terms added in accord with section 7 apply to the code;
121 keep intact all notices of the absence of any warranty; and give all
122 recipients a copy of this License along with the Program.
124 You may charge any price or no price for each copy that you convey,
125 and you may offer support or warranty protection for a fee.
127 5. Conveying Modified Source Versions.
129 You may convey a work based on the Program, or the modifications to
130 produce it from the Program, in the form of source code under the
131 terms of section 4, provided that you also meet all of these conditions:
133 a) The work must carry prominent notices stating that you modified
134 it, and giving a relevant date.
136 b) The work must carry prominent notices stating that it is
137 released under this License and any conditions added under section
138 7. This requirement modifies the requirement in section 4 to
139 "keep intact all notices".
141 c) You must license the entire work, as a whole, under this
142 License to anyone who comes into possession of a copy. This
143 License will therefore apply, along with any applicable section 7
144 additional terms, to the whole of the work, and all its parts,
145 regardless of how they are packaged. This License gives no
146 permission to license the work in any other way, but it does not
147 invalidate such permission if you have separately received it.
149 d) If the work has interactive user interfaces, each must display
150 Appropriate Legal Notices; however, if the Program has interactive
151 interfaces that do not display Appropriate Legal Notices, your
152 work need not make them do so.
154 A compilation of a Covered Work with other separate and independent
155 works, which are not by their nature extensions of the Covered Work,
156 and which are not combined with it such as to form a larger program,
157 in or on a volume of a storage or distribution medium, is called an
158 "aggregate" if the compilation and its resulting copyright are not
159 used to limit the access or legal rights of the compilation's users
160 beyond what the individual works permit. Inclusion of a Covered Work
161 in an aggregate does not cause this License to apply to the other
162 parts of the aggregate.
164 6. Conveying Non-Source Forms.
166 You may convey a Covered Work in object code form under the terms
167 of sections 4 and 5, provided that you also convey the
168 machine-readable Corresponding Source under the terms of this License,
169 in one of these ways:
171 a) Convey the object code in, or embodied in, a physical product
172 (including a physical distribution medium), accompanied by the
173 Corresponding Source fixed on a durable physical medium
174 customarily used for software interchange.
176 b) Convey the object code in, or embodied in, a physical product
177 (including a physical distribution medium), accompanied by a
178 written offer, valid for at least three years and valid for as
179 long as you offer spare parts or customer support for that product
180 model, to give anyone who possesses the object code either (1) a
181 copy of the Corresponding Source for all the software in the
182 product that is covered by this License, on a durable physical
183 medium customarily used for software interchange, for a price no
184 more than your reasonable cost of physically performing this
185 conveying of source, or (2) access to copy the
186 Corresponding Source from a network server at no charge.
188 c) Convey individual copies of the object code with a copy of the
189 written offer to provide the Corresponding Source. This
190 alternative is allowed only occasionally and noncommercially, and
191 only if you received the object code with such an offer, in accord
194 d) Convey the object code by offering access from a designated
195 place (gratis or for a charge), and offer equivalent access to the
196 Corresponding Source in the same way through the same place at no
197 further charge. You need not require recipients to copy the
198 Corresponding Source along with the object code. If the place to
199 copy the object code is a network server, the Corresponding Source
200 may be on a different server (operated by you or a third party)
201 that supports equivalent copying facilities, provided you maintain
202 clear directions next to the object code saying where to find the
203 Corresponding Source. Regardless of what server hosts the
204 Corresponding Source, you remain obligated to ensure that it is
205 available for as long as needed to satisfy these requirements.
207 e) Convey the object code using peer-to-peer transmission, provided
208 you inform other peers where the object code and Corresponding
209 Source of the work are being offered to the general public at no
210 charge under subsection 6d.
212 A "User Product" is either (1) a "consumer product", which means any
213 tangible personal property which is normally used for personal, family,
214 or household purposes, or (2) anything designed or sold for incorporation
215 into a dwelling. In determining whether a product is a consumer product,
216 doubtful cases shall be resolved in favor of coverage. For a particular
217 product received by a particular user, "normally used" refers to a
218 typical or common use of that class of product, regardless of the status
219 of the particular user or of the way in which the particular user
220 actually uses, or expects or is expected to use, the product. A product
221 is a consumer product regardless of whether the product has substantial
222 commercial, industrial or non-consumer uses, unless such uses represent
223 the only significant mode of use of the product.
225 "Installation Information" for a User Product means any methods,
226 procedures, authorization keys, or other information required to install
227 and execute modified versions of a Covered Work in that User Product from
228 a modified version of its Corresponding Source. The information must
229 suffice to ensure that the continued functioning of the modified object
230 code is in no case prevented or interfered with solely because
231 modification has been made.
233 If you convey an object code work under this section in, or with, or
234 specifically for use in, a User Product, and the conveying occurs as
235 part of a transaction in which the right of possession and use of the
236 User Product is transferred to the recipient in perpetuity or for a
237 fixed term (regardless of how the transaction is characterized), the
238 Corresponding Source conveyed under this section must be accompanied
239 by the Installation Information. But this requirement does not apply
240 if neither you nor any third party retains the ability to install
241 modified object code on the User Product (for example, the work has
242 been installed in ROM).
244 The requirement to provide Installation Information does not include a
245 requirement to continue to provide support service, warranty, or updates
246 for a work that has been modified or installed by the recipient, or for
247 the User Product in which it has been modified or installed. Access to a
248 network may be denied when the modification itself materially and
249 adversely affects the operation of the network or violates the rules and
250 protocols for communication across the network.
252 Corresponding Source conveyed, and Installation Information provided,
253 in accord with this section must be in a format that is publicly
254 documented (and with an implementation available to the public in
255 source code form), and must require no special password or key for
256 unpacking, reading or copying.
260 "Additional permissions" are terms that supplement the terms of this
261 License by making exceptions from one or more of its conditions.
262 Additional permissions that are applicable to the entire Program shall
263 be treated as though they were included in this License, to the extent
264 that they are valid under applicable law. If additional permissions
265 apply only to part of the Program, that part may be used separately
266 under those permissions, but the entire Program remains governed by
267 this License without regard to the additional permissions.
269 When you convey a copy of a Covered Work, you may at your option
270 remove any additional permissions from that copy, or from any part of
271 it. (Additional permissions may be written to require their own
272 removal in certain cases when you modify the work.) You may place
273 additional permissions on material, added by you to a Covered Work,
274 for which you have or can give appropriate copyright permission.
276 Notwithstanding any other provision of this License, for material you
277 add to a Covered Work, you may (if authorized by the copyright holders of
278 that material) supplement the terms of this License with terms:
280 a) Disclaiming warranty or limiting liability differently from the
281 terms of sections 15 and 16 of this License; or
283 b) Requiring preservation of specified reasonable legal notices or
284 author attributions in that material; or
286 c) Prohibiting misrepresentation of the origin of that material, or
287 requiring that modified versions of such material be marked in
288 reasonable ways as different from the original version; or
290 d) Limiting the use for publicity purposes of names of licensors or
291 authors of the material; or
293 e) Declining to grant rights under trademark law for use of some
294 trade names, trademarks, or service marks; or
296 f) Requiring indemnification of licensors and authors of that
297 material by anyone who conveys the material (or modified versions of
298 it) with contractual assumptions of liability to the recipient, for
299 any liability that these contractual assumptions directly impose on
300 those licensors and authors.
302 All other non-permissive additional terms are considered "further
303 restrictions" within the meaning of section 10. If the Program as you
304 received it, or any part of it, contains a notice stating that it is
305 governed by this License along with a term that is a further
306 restriction, you may remove that term. If a license document contains
307 a further restriction but permits relicensing or conveying under this
308 License, you may add to a Covered Work material governed by the terms
309 of that license document, provided that the further restriction does
310 not survive such relicensing or conveying.
312 Additional terms may be stated in the form of a separately written
313 license or stated as exceptions to or qualifications of this License.
317 You may not propagate or modify a Covered Work except as expressly
318 provided under this License. Any unauthorized act of propagation or
319 modification automatically terminates your rights under this License
320 (including any patent licenses granted under the third paragraph of
323 However, if you cease all violation of this License, then your
324 license from a particular copyright holder is reinstated (a)
325 provisionally, unless and until the copyright holder explicitly and
326 finally terminates your license, and (b) permanently, if the copyright
327 holder fails to notify you of the violation by some reasonable means
328 prior to 60 days after the cessation.
330 Moreover, your license from a particular copyright holder is
331 reinstated permanently if the copyright holder notifies you of the
332 violation by some reasonable means, this is the first time you have
333 received notice of violation of this License (for any work) from that
334 copyright holder, and you cure the violation prior to 30 days after
335 your receipt of the notice.
337 Termination of your rights under this section does not terminate the
338 licenses of parties who have received copies or rights from you under
339 this License. If your rights have been terminated and not permanently
340 reinstated, you do not qualify to receive new licenses for the same
341 material under section 10.
343 9. Automatic Licensing of Downstream Recipients.
345 Each time you convey a Covered Work, the recipient automatically
346 receives a license from the original licensors, to run, modify and
347 propagate that work, subject to this License. You are not responsible
348 for enforcing compliance by third parties with this License.
350 You may not impose any further restrictions on the exercise of the
351 rights granted or affirmed under this License. For example, you may
352 not impose a license fee, royalty, or other charge for exercise of
353 rights granted under this License, and you may not initiate litigation
354 (including a cross-claim or counterclaim in a lawsuit) alleging that
355 any patent claim is infringed by making, using, selling, offering for
356 sale, or importing the Program or any portion of it.
360 A "contributor" is a copyright holder who authorizes use under this
361 License of the Program or a work on which the Program is based. The
362 work thus licensed is called the contributor's "contributor version".
364 A contributor's "essential patent claims" are all patent claims
365 owned or controlled by the contributor, whether already acquired or
366 hereafter acquired, that would be infringed by some manner, permitted
367 by this License, of making, using, or selling its contributor version,
368 but do not include claims that would be infringed only as a
369 consequence of further modification of the contributor version. For
370 purposes of this definition, "control" includes the right to grant
371 patent sublicenses in a manner consistent with the requirements of
374 Each contributor grants you a non-exclusive, worldwide, royalty-free
375 patent license under the contributor's essential patent claims, to
376 make, use, sell, offer for sale, import and otherwise run, modify and
377 propagate the contents of its contributor version.
379 In the following two paragraphs, a "patent license" is any express
380 agreement or commitment, however denominated, not to enforce a patent
381 (such as an express permission to practice a patent or covenant not to
382 sue for patent infringement). To "grant" such a patent license to a
383 party means to make such an agreement or commitment not to enforce a
384 patent against the party.
386 If you convey a Covered Work, knowingly relying on a patent license,
387 and the Corresponding Source of the work is not available for anyone
388 to copy, free of charge and under the terms of this License, through a
389 publicly available network server or other readily accessible means,
390 then you must either (1) cause the Corresponding Source to be so
391 available, or (2) arrange to deprive yourself of the benefit of the
392 patent license for this particular work, or (3) arrange, in a manner
393 consistent with the requirements of this License, to extend the patent
394 license to downstream recipients. "Knowingly relying" means you have
395 actual knowledge that, but for the patent license, your conveying the
396 Covered Work in a country, or your recipient's use of the Covered Work
397 in a country, would infringe one or more identifiable patents in that
398 country that you have reason to believe are valid.
400 A patent license is "discriminatory" if it does not include within
401 the scope of its coverage, prohibits the exercise of, or is
402 conditioned on the non-exercise of one or more of the rights that are
403 specifically granted under this License. You may not convey a covered
404 work if you are a party to an arrangement with a third party that is
405 in the business of distributing software, under which you make payment
406 to the third party based on the extent of your activity of conveying
407 the work, and under which the third party grants, to any of the
408 parties who would receive the Covered Work from you, a discriminatory
409 patent license (a) in connection with copies of the Covered Work
410 conveyed by you (or copies made from those copies), or (b) primarily
411 for and in connection with specific products or compilations that
412 contain the Covered Work, unless you entered into that arrangement,
413 or that patent license was granted, prior to 28 March 2007.
415 Nothing in this License shall be construed as excluding or limiting
416 any implied license or other defenses to infringement that may
417 otherwise be available to you under applicable patent law.
419 11. Liberty or Death for the Program.
421 If conditions are imposed on you (whether by court order, agreement or
422 otherwise) that contradict the conditions of this License, they do not
423 excuse you from the conditions of this License. If you cannot convey a
424 Covered Work so as to satisfy simultaneously your obligations under this
425 License and any other pertinent obligations, then as a consequence you may
426 not convey it at all. For example, if you agree to terms that obligate you
427 to collect a royalty for further conveying from those to whom you convey
428 the Program, the only way you could satisfy both those terms and this
429 License would be to refrain entirely from conveying the Program.
431 12. Compatibility with GNU GPL and GNU AGPL.
433 Notwithstanding any other provision of this License, you have
434 permission to relicense any Covered Work under the terms of any
435 version of the GNU General Public License and any version of the GNU
436 Affero General Public License published by the Free Software
439 13. Revised Versions of this License.
441 The License Steward may publish revised and/or new versions of
442 GPL.next from time to time. Such new versions will be similar in
443 spirit to the present version, but may differ in detail to address new
444 problems or concerns.
446 Each version is given a distinguishing version number. If the
447 Program specifies that a certain numbered version of GPL.next "or any
448 later version" applies to it, you have the option of following the
449 terms and conditions either of that numbered version or of any later
450 version published by the License Steward. If the Program does not
451 specify a version number of GPL.next, you may choose any version ever
452 published by the License Steward.
454 If the Program specifies that a proxy can decide which future
455 versions of GPL.next can be used, that proxy's public statement of
456 acceptance of a version permanently authorizes you to choose that
457 version for the Program.
459 Later license versions may give you additional or different
460 permissions. However, no additional obligations are imposed on any
461 author or copyright holder as a result of your choosing to follow a
464 14. Disclaimer of Warranty.
466 There is no warranty for the program, to the extent permitted by
467 applicable law. Except when otherwise stated in writing the
468 copyright holders and/or other parties provide the Program "as is"
469 without warranty of any kind, either express or implied, including,
470 but not limited to, the implied warranties of merchantability and
471 fitness for a particular purpose. The entire risk as to the quality
472 and performance of the Program is with you. Should the Program prove
473 defective, you assume the cost of all necessary servicing, repair or
476 15. Limitation of Liability.
478 In no event unless required by applicable law or agreed to in
479 writing will any copyright holder, or any other party who modifies
480 and/or conveys the Program as permitted above, be liable to you for
481 damages, including any general, special, incidental or consequential
482 damages arising out of the use or inability to use the Program
483 (including but not limited to loss of data or data being rendered
484 inaccurate or losses sustained by you or third parties or a failure of
485 the Program to operate with any other programs), even if such holder
486 or other party has been advised of the possibility of such damages.
