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

|
|
|
8 Preamble
|
|
|
9
|
|
|
10 The GNU General Public License is a free, copyleft license for
|
|
|
11 software and other kinds of works.
|
|
|
12
|
|
|
13 The licenses for most software and other practical works are designed
|
|
|
14 to take away your freedom to share and change the works. By contrast,
|
|
|
15 the GNU General Public License is intended to guarantee your freedom to
|
|
|
16 share and change all versions of a program--to make sure it remains free
|
|
|
17 software for all its users. We, the Free Software Foundation, use the
|
|
|
18 GNU General Public License for most of our software; it applies also to
|
|
|
19 any other work released this way by its authors. You can apply it to
|
|
|
20 your programs, too.
|
|
|
21
|
|
|
22 When we speak of free software, we are referring to freedom, not
|
|
|
23 price. Our General Public Licenses are designed to make sure that you
|
|
|
24 have the freedom to distribute copies of free software (and charge for
|
|
|
25 them if you wish), that you receive source code or can get it if you
|
|
|
26 want it, that you can change the software or use pieces of it in new
|
|
|
27 free programs, and that you know you can do these things.
|
|
|
28
|
|
|
29 To protect your rights, we need to prevent others from denying you
|
|
|
30 these rights or asking you to surrender the rights. Therefore, you have
|
|
|
31 certain responsibilities if you distribute copies of the software, or if
|
|
|
32 you modify it: responsibilities to respect the freedom of others.
|
|
|
33
|
|
|
34 For example, if you distribute copies of such a program, whether
|
|
|
35 gratis or for a fee, you must pass on to the recipients the same
|
|
|
36 freedoms that you received. You must make sure that they, too, receive
|
|
|
37 or can get the source code. And you must show them these terms so they
|
|
|
38 know their rights.
|
|
|
39
|
|
|
40 Developers that use the GNU GPL protect your rights with two steps:
|
|
|
41 (1) assert copyright on the software, and (2) offer you this License
|
|
|
42 giving you legal permission to copy, distribute and/or modify it.
|
|
|
43
|
|
|
44 For the developers' and authors' protection, the GPL clearly explains
|
|
|
45 that there is no warranty for this free software. For both users' and
|
|
|
46 authors' sake, the GPL requires that modified versions be marked as
|
|
|
47 changed, so that their problems will not be attributed erroneously to
|
|
|
48 authors of previous versions.
|
|
|
49
|
|
|
50 Some devices are designed to deny users access to install or run
|
|
|
51 modified versions of the software inside them, although the manufacturer
|
|
|
52 can do so. This is fundamentally incompatible with the aim of
|
|
|
53 protecting users' freedom to change the software. The systematic
|
|
|
54 pattern of such abuse occurs in the area of products for individuals to
|
|
|
55 use, which is precisely where it is most unacceptable. Therefore, we
|
|
|
56 have designed this version of the GPL to prohibit the practice for those
|
|
|
57 products. If such problems arise substantially in other domains, we
|
|
|
58 stand ready to extend this provision to those domains in future versions
|
|
|
59 of the GPL, as needed to protect the freedom of users.
|
|
|
60
|
|
|
61 Finally, every program is threatened constantly by software patents.
|
|
|
62 States should not allow patents to restrict development and use of
|
|
|
63 software on general-purpose computers, but in those that do, we wish to
|
|
|
64 avoid the special danger that patents applied to a free program could
|
|
|
65 make it effectively proprietary. To prevent this, the GPL assures that
|
|
|
66 patents cannot be used to render the program non-free.
|
|
|
67
|
|
|
68 The precise terms and conditions for copying, distribution and
|
|
|
69 modification follow.
|
|
|
70
|
|
|
71 TERMS AND CONDITIONS
|
|
|
72
|
|
|
73 0. Definitions.
|
|
|
74
|
|
|
75 "This License" refers to version 3 of the GNU General Public License.
|
|
|
76
|
|
|
77 "Copyright" also means copyright-like laws that apply to other kinds of
|
|
|
78 works, such as semiconductor masks.
|
|
|
79
|
|
|
80 "The Program" refers to any copyrightable work licensed under this
|
|
|
81 License. Each licensee is addressed as "you". "Licensees" and
|
|
|
82 "recipients" may be individuals or organizations.
|
|
|
83
|
|
|
84 To "modify" a work means to copy from or adapt all or part of the work
|
|
|
85 in a fashion requiring copyright permission, other than the making of an
|
|
|
86 exact copy. The resulting work is called a "modified version" of the
|
|
|
87 earlier work or a work "based on" the earlier work.
|
|
|
88
|
|
|
89 A "covered work" means either the unmodified Program or a work based
|
|
|
90 on the Program.
|
|
|
91
|
|
|
92 To "propagate" a work means to do anything with it that, without
|
|
|
93 permission, would make you directly or secondarily liable for
|
|
|
94 infringement under applicable copyright law, except executing it on a
|
|
|
95 computer or modifying a private copy. Propagation includes copying,
|
|
|
96 distribution (with or without modification), making available to the
|
|
|
97 public, and in some countries other activities as well.
|
|
|
98
|
|
|
99 To "convey" a work means any kind of propagation that enables other
|
|
|
100 parties to make or receive copies. Mere interaction with a user through
|
|
|
101 a computer network, with no transfer of a copy, is not conveying.
|
|
|
102
|
|
|
103 An interactive user interface displays "Appropriate Legal Notices"
|
|
|
104 to the extent that it includes a convenient and prominently visible
|
|
|
105 feature that (1) displays an appropriate copyright notice, and (2)
|
|
|
106 tells the user that there is no warranty for the work (except to the
|
|
|
107 extent that warranties are provided), that licensees may convey the
|
|
|
108 work under this License, and how to view a copy of this License. If
|
|
|
109 the interface presents a list of user commands or options, such as a
|
|
|
110 menu, a prominent item in the list meets this criterion.
|
|
|
111
|
|
|
112 1. Source Code.
|
|
|
113
|
|
|
114 The "source code" for a work means the preferred form of the work
|
|
|
115 for making modifications to it. "Object code" means any non-source
|
|
|
116 form of a work.
|
|
|
117
|
|
|
118 A "Standard Interface" means an interface that either is an official
|
|
|
119 standard defined by a recognized standards body, or, in the case of
|
|
|
120 interfaces specified for a particular programming language, one that
|
|
|
121 is widely used among developers working in that language.
|
|
|
122
|
|
|
123 The "System Libraries" of an executable work include anything, other
|
|
|
124 than the work as a whole, that (a) is included in the normal form of
|
|
|
125 packaging a Major Component, but which is not part of that Major
|
|
|
126 Component, and (b) serves only to enable use of the work with that
|
|
|
127 Major Component, or to implement a Standard Interface for which an
|
|
|
128 implementation is available to the public in source code form. A
|
|
|
129 "Major Component", in this context, means a major essential component
|
|
|
130 (kernel, window system, and so on) of the specific operating system
|
|
|
131 (if any) on which the executable work runs, or a compiler used to
|
|
|
132 produce the work, or an object code interpreter used to run it.
|
|
|
133
|
|
|
134 The "Corresponding Source" for a work in object code form means all
|
|
|
135 the source code needed to generate, install, and (for an executable
|
|
|
136 work) run the object code and to modify the work, including scripts to
|
|
|
137 control those activities. However, it does not include the work's
|
|
|
138 System Libraries, or general-purpose tools or generally available free
|
|
|
139 programs which are used unmodified in performing those activities but
|
|
|
140 which are not part of the work. For example, Corresponding Source
|
|
|
141 includes interface definition files associated with source files for
|
|
|
142 the work, and the source code for shared libraries and dynamically
|
|
|
143 linked subprograms that the work is specifically designed to require,
|
|
|
144 such as by intimate data communication or control flow between those
|
|
|
145 subprograms and other parts of the work.
|
|
|
146
|
|
|
147 The Corresponding Source need not include anything that users
|
|
|
148 can regenerate automatically from other parts of the Corresponding
|
|
|
149 Source.
|
|
|
150
|
|
|
151 The Corresponding Source for a work in source code form is that
|
|
|
152 same work.
|
|
|
153
|
|
|
154 2. Basic Permissions.
|
|
|
155
|
|
|
156 All rights granted under this License are granted for the term of
|
|
|
157 copyright on the Program, and are irrevocable provided the stated
|
|
|
158 conditions are met. This License explicitly affirms your unlimited
|
|
|
159 permission to run the unmodified Program. The output from running a
|
|
|
160 covered work is covered by this License only if the output, given its
|
|
|
161 content, constitutes a covered work. This License acknowledges your
|
|
|
162 rights of fair use or other equivalent, as provided by copyright law.
|
|
|
163
|
|
|
164 You may make, run and propagate covered works that you do not
|
|
|
165 convey, without conditions so long as your license otherwise remains
|
|
|
166 in force. You may convey covered works to others for the sole purpose
|
|
|
167 of having them make modifications exclusively for you, or provide you
|
|
|
168 with facilities for running those works, provided that you comply with
|
|
|
169 the terms of this License in conveying all material for which you do
|
|
|
170 not control copyright. Those thus making or running the covered works
|
|
|
171 for you must do so exclusively on your behalf, under your direction
|
|
|
172 and control, on terms that prohibit them from making any copies of
|
|
|
173 your copyrighted material outside their relationship with you.
|
|
|
174
|
|
|
175 Conveying under any other circumstances is permitted solely under
|
|
|
176 the conditions stated below. Sublicensing is not allowed; section 10
|
|
|
177 makes it unnecessary.
|
|
|
178
|
|
|
179 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
|
|
|
180
|
|
|
181 No covered work shall be deemed part of an effective technological
|
|
|
182 measure under any applicable law fulfilling obligations under article
|
|
|
183 11 of the WIPO copyright treaty adopted on 20 December 1996, or
|
|
|
184 similar laws prohibiting or restricting circumvention of such
|
|
|
185 measures.
|
|
|
186
|
|
|
187 When you convey a covered work, you waive any legal power to forbid
|
|
|
188 circumvention of technological measures to the extent such circumvention
|
|
|
189 is effected by exercising rights under this License with respect to
|
|
|
190 the covered work, and you disclaim any intention to limit operation or
|
|
|
191 modification of the work as a means of enforcing, against the work's
|
|
|
192 users, your or third parties' legal rights to forbid circumvention of
|
|
|
193 technological measures.
|
|
|
194
|
|
|
195 4. Conveying Verbatim Copies.
|
|
|
196
|
|
|
197 You may convey verbatim copies of the Program's source code as you
|
|
|
198 receive it, in any medium, provided that you conspicuously and
|
|
|
199 appropriately publish on each copy an appropriate copyright notice;
|
|
|
200 keep intact all notices stating that this License and any
|
|
|
201 non-permissive terms added in accord with section 7 apply to the code;
|
|
|
202 keep intact all notices of the absence of any warranty; and give all
|
|
|
203 recipients a copy of this License along with the Program.
|
|
|
204
|
|
|
205 You may charge any price or no price for each copy that you convey,
|
|
|
206 and you may offer support or warranty protection for a fee.
|
|
|
207
|
|
|
208 5. Conveying Modified Source Versions.
|
|
|
209
|
|
|
210 You may convey a work based on the Program, or the modifications to
|
|
|
211 produce it from the Program, in the form of source code under the
|
|
|
212 terms of section 4, provided that you also meet all of these conditions:
|
|
|
213
|
|
|
214 a) The work must carry prominent notices stating that you modified
|
|
|
215 it, and giving a relevant date.
|
|
|
216
|
|
|
217 b) The work must carry prominent notices stating that it is
|
|
|
218 released under this License and any conditions added under section
|
|
|
219 7. This requirement modifies the requirement in section 4 to
|
|
|
220 "keep intact all notices".
|
|
|
221
|
|
|
222 c) You must license the entire work, as a whole, under this
|
|
|
223 License to anyone who comes into possession of a copy. This
|
|
|
224 License will therefore apply, along with any applicable section 7
|
|
|
225 additional terms, to the whole of the work, and all its parts,
|
|
|
226 regardless of how they are packaged. This License gives no
|
|
|
227 permission to license the work in any other way, but it does not
|
|
|
228 invalidate such permission if you have separately received it.
|
|
|
229
|
|
|
230 d) If the work has interactive user interfaces, each must display
|
|
|
231 Appropriate Legal Notices; however, if the Program has interactive
|
|
|
232 interfaces that do not display Appropriate Legal Notices, your
|
|
|
233 work need not make them do so.
|
|
|
234
|
|
|
235 A compilation of a covered work with other separate and independent
|
|
|
236 works, which are not by their nature extensions of the covered work,
|
|
|
237 and which are not combined with it such as to form a larger program,
|
|
|
238 in or on a volume of a storage or distribution medium, is called an
|
|
|
239 "aggregate" if the compilation and its resulting copyright are not
|
|
|
240 used to limit the access or legal rights of the compilation's users
|
|
|
241 beyond what the individual works permit. Inclusion of a covered work
|
|
|
242 in an aggregate does not cause this License to apply to the other
|
|
|
243 parts of the aggregate.
|
|
|
244
|
|
|
245 6. Conveying Non-Source Forms.
|
|
|
246
|
|
|
247 You may convey a covered work in object code form under the terms
|
|
|
248 of sections 4 and 5, provided that you also convey the
|
|
|
249 machine-readable Corresponding Source under the terms of this License,
|
|
|
250 in one of these ways:
|
|
|
251
|
|
|
252 a) Convey the object code in, or embodied in, a physical product
|
|
|
253 (including a physical distribution medium), accompanied by the
|
|
|
254 Corresponding Source fixed on a durable physical medium
|
|
|
255 customarily used for software interchange.
|
|
|
256
|
|
|
257 b) Convey the object code in, or embodied in, a physical product
|
|
|
258 (including a physical distribution medium), accompanied by a
|
|
|
259 written offer, valid for at least three years and valid for as
|
|
|
260 long as you offer spare parts or customer support for that product
|
|
|
261 model, to give anyone who possesses the object code either (1) a
|
|
|
262 copy of the Corresponding Source for all the software in the
|
|
|
263 product that is covered by this License, on a durable physical
|
|
|
264 medium customarily used for software interchange, for a price no
|
|
|
265 more than your reasonable cost of physically performing this
|
|
|
266 conveying of source, or (2) access to copy the
|
|
|
267 Corresponding Source from a network server at no charge.
|
|
|
268
|
|
|
269 c) Convey individual copies of the object code with a copy of the
|
|
|
270 written offer to provide the Corresponding Source. This
|
|
|
271 alternative is allowed only occasionally and noncommercially, and
|
|
|
272 only if you received the object code with such an offer, in accord
|
|
|
273 with subsection 6b.
|
|
|
274
|
|
|
275 d) Convey the object code by offering access from a designated
|
|
|
276 place (gratis or for a charge), and offer equivalent access to the
|
|
|
277 Corresponding Source in the same way through the same place at no
|
|
|
278 further charge. You need not require recipients to copy the
|
|
|
279 Corresponding Source along with the object code. If the place to
|
|
|
280 copy the object code is a network server, the Corresponding Source
|
|
|
281 may be on a different server (operated by you or a third party)
|
|
|
282 that supports equivalent copying facilities, provided you maintain
|
|
|
283 clear directions next to the object code saying where to find the
|
|
|
284 Corresponding Source. Regardless of what server hosts the
|
|
|
285 Corresponding Source, you remain obligated to ensure that it is
|
|
|
286 available for as long as needed to satisfy these requirements.
|
|
|
287
|
|
|
288 e) Convey the object code using peer-to-peer transmission, provided
|
|
|
289 you inform other peers where the object code and Corresponding
|
|
|
290 Source of the work are being offered to the general public at no
|
|
|
291 charge under subsection 6d.
|
|
|
292
|
|
|
293 A separable portion of the object code, whose source code is excluded
|
|
|
294 from the Corresponding Source as a System Library, need not be
|
|
|
295 included in conveying the object code work.
|
|
|
296
|
|
|
297 A "User Product" is either (1) a "consumer product", which means any
|
|
|
298 tangible personal property which is normally used for personal, family,
|
|
|
299 or household purposes, or (2) anything designed or sold for incorporation
|
|
|
300 into a dwelling. In determining whether a product is a consumer product,
|
|
|
301 doubtful cases shall be resolved in favor of coverage. For a particular
|
|
|
302 product received by a particular user, "normally used" refers to a
|
|
|
303 typical or common use of that class of product, regardless of the status
|
|
|
304 of the particular user or of the way in which the particular user
|
|
|
305 actually uses, or expects or is expected to use, the product. A product
|
|
|
306 is a consumer product regardless of whether the product has substantial
|
|
|
307 commercial, industrial or non-consumer uses, unless such uses represent
|
|
|
308 the only significant mode of use of the product.
|
|
|
309
|
|
|
310 "Installation Information" for a User Product means any methods,
|
|
|
311 procedures, authorization keys, or other information required to install
|
|
|
312 and execute modified versions of a covered work in that User Product from
|
|
|
313 a modified version of its Corresponding Source. The information must
|
|
|
314 suffice to ensure that the continued functioning of the modified object
|
|
|
315 code is in no case prevented or interfered with solely because
|
|
|
316 modification has been made.
|
|
|
317
|
|
|
318 If you convey an object code work under this section in, or with, or
|
|
|
319 specifically for use in, a User Product, and the conveying occurs as
|
|
|
320 part of a transaction in which the right of possession and use of the
|
|
|
321 User Product is transferred to the recipient in perpetuity or for a
|
|
|
322 fixed term (regardless of how the transaction is characterized), the
|
|
|
323 Corresponding Source conveyed under this section must be accompanied
|
|
|
324 by the Installation Information. But this requirement does not apply
|
|
|
325 if neither you nor any third party retains the ability to install
|
|
|
326 modified object code on the User Product (for example, the work has
|
|
|
327 been installed in ROM).
|
|
|
328
|
|
|
329 The requirement to provide Installation Information does not include a
|
|
|
330 requirement to continue to provide support service, warranty, or updates
|
|
|
331 for a work that has been modified or installed by the recipient, or for
|
|
|
332 the User Product in which it has been modified or installed. Access to a
|
|
|
333 network may be denied when the modification itself materially and
|
|
|
334 adversely affects the operation of the network or violates the rules and
|
|
|
335 protocols for communication across the network.
|
|
|
336
|
|
|
337 Corresponding Source conveyed, and Installation Information provided,
|
|
|
338 in accord with this section must be in a format that is publicly
|
|
|
339 documented (and with an implementation available to the public in
|
|
|
340 source code form), and must require no special password or key for
|
|
|
341 unpacking, reading or copying.
|
|
|
342
|
|
|
343 7. Additional Terms.
|
|
|
344
|
|
|
345 "Additional permissions" are terms that supplement the terms of this
|
|
|
346 License by making exceptions from one or more of its conditions.
|
|
|
347 Additional permissions that are applicable to the entire Program shall
|
|
|
348 be treated as though they were included in this License, to the extent
|
|
|
349 that they are valid under applicable law. If additional permissions
|
|
|
350 apply only to part of the Program, that part may be used separately
|
|
|
351 under those permissions, but the entire Program remains governed by
|
|
|
352 this License without regard to the additional permissions.
|
|
|
353
|
|
|
354 When you convey a copy of a covered work, you may at your option
|
|
|
355 remove any additional permissions from that copy, or from any part of
|
|
|
356 it. (Additional permissions may be written to require their own
|
|
|
357 removal in certain cases when you modify the work.) You may place
|
|
|
358 additional permissions on material, added by you to a covered work,
|
|
|
359 for which you have or can give appropriate copyright permission.
|
|
|
360
|
|
|
361 Notwithstanding any other provision of this License, for material you
|
|
|
362 add to a covered work, you may (if authorized by the copyright holders of
|
|
|
363 that material) supplement the terms of this License with terms:
|
|
|
364
|
|
|
365 a) Disclaiming warranty or limiting liability differently from the
|
|
|
366 terms of sections 15 and 16 of this License; or
|
|
|
367
|
|
|
368 b) Requiring preservation of specified reasonable legal notices or
|
|
|
369 author attributions in that material or in the Appropriate Legal
|
|
|
370 Notices displayed by works containing it; or
|
|
|
371
|
|
|
372 c) Prohibiting misrepresentation of the origin of that material, or
|
|
|
373 requiring that modified versions of such material be marked in
|
|
|
374 reasonable ways as different from the original version; or
|
|
|
375
|
|
|
376 d) Limiting the use for publicity purposes of names of licensors or
|
|
|
377 authors of the material; or
|
|
|
378
|
|
|
379 e) Declining to grant rights under trademark law for use of some
|
|
|
380 trade names, trademarks, or service marks; or
|
|
|
381
|
|
|
382 f) Requiring indemnification of licensors and authors of that
|
|
|
383 material by anyone who conveys the material (or modified versions of
|
|
|
384 it) with contractual assumptions of liability to the recipient, for
|
|
|
385 any liability that these contractual assumptions directly impose on
|
|
|
386 those licensors and authors.
|
|
|
387
|
|
|
388 All other non-permissive additional terms are considered "further
|
|
|
389 restrictions" within the meaning of section 10. If the Program as you
|
|
|
390 received it, or any part of it, contains a notice stating that it is
|
|
|
391 governed by this License along with a term that is a further
|
|
|
392 restriction, you may remove that term. If a license document contains
|
|
|
393 a further restriction but permits relicensing or conveying under this
|
|
|
394 License, you may add to a covered work material governed by the terms
|
|
|
395 of that license document, provided that the further restriction does
|
|
|
396 not survive such relicensing or conveying.
|
|
|
397
|
|
|
398 If you add terms to a covered work in accord with this section, you
|
|
|
399 must place, in the relevant source files, a statement of the
|
|
|
400 additional terms that apply to those files, or a notice indicating
|
|
|
401 where to find the applicable terms.
|
|
|
402
|
|
|
403 Additional terms, permissive or non-permissive, may be stated in the
|
|
|
404 form of a separately written license, or stated as exceptions;
|
|
|
405 the above requirements apply either way.
|
|
|
406
|
|
|
407 8. Termination.
|
|
|
408
|
|
|
409 You may not propagate or modify a covered work except as expressly
|
|
|
410 provided under this License. Any attempt otherwise to propagate or
|
|
|
411 modify it is void, and will automatically terminate your rights under
|
|
|
412 this License (including any patent licenses granted under the third
|
|
|
413 paragraph of section 11).
|
|
|
414
|
|
|
415 However, if you cease all violation of this License, then your
|
|
|
416 license from a particular copyright holder is reinstated (a)
|
|
|
417 provisionally, unless and until the copyright holder explicitly and
|
|
|
418 finally terminates your license, and (b) permanently, if the copyright
|
|
|
419 holder fails to notify you of the violation by some reasonable means
|
|
|
420 prior to 60 days after the cessation.
|
|
|
421
|
|
|
422 Moreover, your license from a particular copyright holder is
|
|
|
423 reinstated permanently if the copyright holder notifies you of the
|
|
|
424 violation by some reasonable means, this is the first time you have
|
|
|
425 received notice of violation of this License (for any work) from that
|
|
|
426 copyright holder, and you cure the violation prior to 30 days after
|
|
|
427 your receipt of the notice.
|
|
|
428
|
|
|
429 Termination of your rights under this section does not terminate the
|
|
|
430 licenses of parties who have received copies or rights from you under
|
|
|
431 this License. If your rights have been terminated and not permanently
|
|
|
432 reinstated, you do not qualify to receive new licenses for the same
|
|
|
433 material under section 10.
|
|
|
434
|
|
|
435 9. Acceptance Not Required for Having Copies.
|
|
|
436
|
|
|
437 You are not required to accept this License in order to receive or
|
|
|
438 run a copy of the Program. Ancillary propagation of a covered work
|
|
|
439 occurring solely as a consequence of using peer-to-peer transmission
|
|
|
440 to receive a copy likewise does not require acceptance. However,
|
|
|
441 nothing other than this License grants you permission to propagate or
|
|
|
442 modify any covered work. These actions infringe copyright if you do
|
|
|
443 not accept this License. Therefore, by modifying or propagating a
|
|
|
444 covered work, you indicate your acceptance of this License to do so.
|
|
|
445
|
|
|
446 10. Automatic Licensing of Downstream Recipients.
|
|
|
447
|
|
|
448 Each time you convey a covered work, the recipient automatically
|
|
|
449 receives a license from the original licensors, to run, modify and
|
|
|
450 propagate that work, subject to this License. You are not responsible
|
|
|
451 for enforcing compliance by third parties with this License.
|
|
|
452
|
|
|
453 An "entity transaction" is a transaction transferring control of an
|
|
|
454 organization, or substantially all assets of one, or subdividing an
|
|
|
455 organization, or merging organizations. If propagation of a covered
|
|
|
456 work results from an entity transaction, each party to that
|
|
|
457 transaction who receives a copy of the work also receives whatever
|
|
|
458 licenses to the work the party's predecessor in interest had or could
|
|
|
459 give under the previous paragraph, plus a right to possession of the
|
|
|
460 Corresponding Source of the work from the predecessor in interest, if
|
|
|
461 the predecessor has it or can get it with reasonable efforts.
|
|
|
462
|
|
|
463 You may not impose any further restrictions on the exercise of the
|
|
|
464 rights granted or affirmed under this License. For example, you may
|
|
|
465 not impose a license fee, royalty, or other charge for exercise of
|
|
|
466 rights granted under this License, and you may not initiate litigation
|
|
|
467 (including a cross-claim or counterclaim in a lawsuit) alleging that
|
|
|
468 any patent claim is infringed by making, using, selling, offering for
|
|
|
469 sale, or importing the Program or any portion of it.
|
|
|
470
|
|
|
471 11. Patents.
|
|
|
472
|
|
|
473 A "contributor" is a copyright holder who authorizes use under this
|
|
|
474 License of the Program or a work on which the Program is based. The
|
|
|
475 work thus licensed is called the contributor's "contributor version".
|
|
|
476
|
|
|
477 A contributor's "essential patent claims" are all patent claims
|
|
|
478 owned or controlled by the contributor, whether already acquired or
|
|
|
479 hereafter acquired, that would be infringed by some manner, permitted
|
|
|
480 by this License, of making, using, or selling its contributor version,
|
|
|
481 but do not include claims that would be infringed only as a
|
|
|
482 consequence of further modification of the contributor version. For
|
|
|
483 purposes of this definition, "control" includes the right to grant
|
|
|
484 patent sublicenses in a manner consistent with the requirements of
|
|
|
485 this License.
|
|
|
486
|
|
|
487 Each contributor grants you a non-exclusive, worldwide, royalty-free
|
|
|
488 patent license under the contributor's essential patent claims, to
|
|
|
489 make, use, sell, offer for sale, import and otherwise run, modify and
|
|
|
490 propagate the contents of its contributor version.
|
|
|
491
|
|
|
492 In the following three paragraphs, a "patent license" is any express
|
|
|
493 agreement or commitment, however denominated, not to enforce a patent
|
|
|
494 (such as an express permission to practice a patent or covenant not to
|
|
|
495 sue for patent infringement). To "grant" such a patent license to a
|
|
|
496 party means to make such an agreement or commitment not to enforce a
|
|
|
497 patent against the party.
|
|
|
498
|
|
|
499 If you convey a covered work, knowingly relying on a patent license,
|
|
|
500 and the Corresponding Source of the work is not available for anyone
|
|
|
501 to copy, free of charge and under the terms of this License, through a
|
|
|
502 publicly available network server or other readily accessible means,
|
|
|
503 then you must either (1) cause the Corresponding Source to be so
|
|
|
504 available, or (2) arrange to deprive yourself of the benefit of the
|
|
|
505 patent license for this particular work, or (3) arrange, in a manner
|
|
|
506 consistent with the requirements of this License, to extend the patent
|
|
|
507 license to downstream recipients. "Knowingly relying" means you have
|
|
|
508 actual knowledge that, but for the patent license, your conveying the
|
|
|
509 covered work in a country, or your recipient's use of the covered work
|
|
|
510 in a country, would infringe one or more identifiable patents in that
|
|
|
511 country that you have reason to believe are valid.
|
|
|
512
|
|
|
513 If, pursuant to or in connection with a single transaction or
|
|
|
514 arrangement, you convey, or propagate by procuring conveyance of, a
|
|
|
515 covered work, and grant a patent license to some of the parties
|
|
|
516 receiving the covered work authorizing them to use, propagate, modify
|
|
|
517 or convey a specific copy of the covered work, then the patent license
|
|
|
518 you grant is automatically extended to all recipients of the covered
|
|
|
519 work and works based on it.
|
|
|
520
|
|
|
521 A patent license is "discriminatory" if it does not include within
|
|
|
522 the scope of its coverage, prohibits the exercise of, or is
|
|
|
523 conditioned on the non-exercise of one or more of the rights that are
|
|
|
524 specifically granted under this License. You may not convey a covered
|
|
|
525 work if you are a party to an arrangement with a third party that is
|
|
|
526 in the business of distributing software, under which you make payment
|
|
|
527 to the third party based on the extent of your activity of conveying
|
|
|
528 the work, and under which the third party grants, to any of the
|
|
|
529 parties who would receive the covered work from you, a discriminatory
|
|
|
530 patent license (a) in connection with copies of the covered work
|
|
|
531 conveyed by you (or copies made from those copies), or (b) primarily
|
|
|
532 for and in connection with specific products or compilations that
|
|
|
533 contain the covered work, unless you entered into that arrangement,
|
|
|
534 or that patent license was granted, prior to 28 March 2007.
|
|
|
535
|
|
|
536 Nothing in this License shall be construed as excluding or limiting
|
|
|
537 any implied license or other defenses to infringement that may
|
|
|
538 otherwise be available to you under applicable patent law.
|
|
|
539
|
|
|
540 12. No Surrender of Others' Freedom.
|
|
|
541
|
|
|
542 If conditions are imposed on you (whether by court order, agreement or
|
|
|
543 otherwise) that contradict the conditions of this License, they do not
|
|
|
544 excuse you from the conditions of this License. If you cannot convey a
|
|
|
545 covered work so as to satisfy simultaneously your obligations under this
|
|
|
546 License and any other pertinent obligations, then as a consequence you may
|
|
|
547 not convey it at all. For example, if you agree to terms that obligate you
|
|
|
548 to collect a royalty for further conveying from those to whom you convey
|
|
|
549 the Program, the only way you could satisfy both those terms and this
|
|
|
550 License would be to refrain entirely from conveying the Program.
|
|
|
551
|
|
|
552 13. Use with the GNU Affero General Public License.
|
|
|
553
|
|
|
554 Notwithstanding any other provision of this License, you have
|
|
|
555 permission to link or combine any covered work with a work licensed
|
|
|
556 under version 3 of the GNU Affero General Public License into a single
|
|
|
557 combined work, and to convey the resulting work. The terms of this
|
|
|
558 License will continue to apply to the part which is the covered work,
|
|
|
559 but the special requirements of the GNU Affero General Public License,
|
|
|
560 section 13, concerning interaction through a network will apply to the
|
|
|
561 combination as such.
|
|
|
562
|
|
|
563 14. Revised Versions of this License.
|
|
|
564
|
|
|
565 The Free Software Foundation may publish revised and/or new versions of
|
|
|
566 the GNU General Public License from time to time. Such new versions will
|
|
|
567 be similar in spirit to the present version, but may differ in detail to
|
|
|
568 address new problems or concerns.
|
|
|
569
|
|
|
570 Each version is given a distinguishing version number. If the
|
|
|
571 Program specifies that a certain numbered version of the GNU General
|
|
|
572 Public License "or any later version" applies to it, you have the
|
|
|
573 option of following the terms and conditions either of that numbered
|
|
|
574 version or of any later version published by the Free Software
|
|
|
575 Foundation. If the Program does not specify a version number of the
|
|
|
576 GNU General Public License, you may choose any version ever published
|
|
|
577 by the Free Software Foundation.
|
|
|
578
|
|
|
579 If the Program specifies that a proxy can decide which future
|
|
|
580 versions of the GNU General Public License can be used, that proxy's
|
|
|
581 public statement of acceptance of a version permanently authorizes you
|
|
|
582 to choose that version for the Program.
|
|
|
583
|
|
|
584 Later license versions may give you additional or different
|
|
|
585 permissions. However, no additional obligations are imposed on any
|
|
|
586 author or copyright holder as a result of your choosing to follow a
|
|
|
587 later version.
|
|
|
588
|
|
|
589 15. Disclaimer of Warranty.
|
|
|
590
|
|
|
591 THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
|
|
|
592 APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
|
|
|
593 HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
|
|
|
594 OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
|
|
|
595 THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
|
|
|
596 PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
|
|
|
597 IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
|
|
|
598 ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
|
|
|
599
|
|
|
600 16. Limitation of Liability.
|
|
|
601
|
|
|
602 IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
|
|
|
603 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
|
|
|
604 THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
|
|
|
605 GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
|
|
|
606 USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
|
|
|
607 DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
|
|
|
608 PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
|
|
|
609 EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
|
|
|
610 SUCH DAMAGES.
|
|
|
611
|
|
|
612 17. Interpretation of Sections 15 and 16.
|
|
|
613
|
|
|
614 If the disclaimer of warranty and limitation of liability provided
|
|
|
615 above cannot be given local legal effect according to their terms,
|
|
|
616 reviewing courts shall apply local law that most closely approximates
|
|
|
617 an absolute waiver of all civil liability in connection with the
|
|
|
618 Program, unless a warranty or assumption of liability accompanies a
|
|
|
619 copy of the Program in return for a fee.

|
|
|
623 How to Apply These Terms to Your New Programs
|
|
|
624
|
|
|
625 If you develop a new program, and you want it to be of the greatest
|
|
|
626 possible use to the public, the best way to achieve this is to make it
|
|
|
627 free software which everyone can redistribute and change under these terms.
|
|
|
628
|
|
|
629 To do so, attach the following notices to the program. It is safest
|
|
|
630 to attach them to the start of each source file to most effectively
|
|
|
631 state the exclusion of warranty; and each file should have at least
|
|
|
632 the "copyright" line and a pointer to where the full notice is found.
|
|
|
633
|
|
|
634 <one line to give the program's name and a brief idea of what it does.>
|
|
|
635 Copyright (C) <year> <name of author>

|

641
|
|
|
642 This program is distributed in the hope that it will be useful,
|
|
|
643 but WITHOUT ANY WARRANTY; without even the implied warranty of
|
|
|
644 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
|
|
|
645 GNU General Public License for more details.

647 You should have received a copy of the GNU General Public License
|
|

649
|
|
|
650 Also add information on how to contact you by electronic and paper mail.
|
|
|
651
|
|
|
652 If the program does terminal interaction, make it output a short
|
|
|
653 notice like this when it starts in an interactive mode:
|
|
|
654
|
|
|

659
|

|
660 The hypothetical commands `show w' and `show c' should show the appropriate
|
|
|
661 parts of the General Public License. Of course, your program's commands
|

662 might be different; for a GUI interface, you would use an "about box".
|
|

663
|
|
|
664 You should also get your employer (if you work as a programmer) or school,
|
|
|
665 if any, to sign a "copyright disclaimer" for the program, if necessary.

669 The GNU General Public License does not permit incorporating your program

671 may consider it more useful to permit linking proprietary applications with
|
|
|
672 the library. If this is what you want to do, use the GNU Lesser General

|
|
|
745 Preamble
|
|
|
746
|
|
|
747 The licenses for most software are designed to take away your
|
|
|
748 freedom to share and change it. By contrast, the GNU General Public
|
|
|
749 Licenses are intended to guarantee your freedom to share and change
|
|
|
750 free software--to make sure the software is free for all its users.
|
|
|
751
|
|
|
752 This license, the Library General Public License, applies to some
|
|
|
753 specially designated Free Software Foundation software, and to any
|
|
|
754 other libraries whose authors decide to use it. You can use it for
|
|
|
755 your libraries, too.
|
|
|
756
|
|
|
757 When we speak of free software, we are referring to freedom, not
|
|
|
758 price. Our General Public Licenses are designed to make sure that you
|
|
|
759 have the freedom to distribute copies of free software (and charge for
|
|
|
760 this service if you wish), that you receive source code or can get it
|
|
|
761 if you want it, that you can change the software or use pieces of it
|
|
|
762 in new free programs; and that you know you can do these things.
|
|
|
763
|
|
|
764 To protect your rights, we need to make restrictions that forbid
|
|
|
765 anyone to deny you these rights or to ask you to surrender the rights.
|
|
|
766 These restrictions translate to certain responsibilities for you if
|
|
|
767 you distribute copies of the library, or if you modify it.
|
|
|
768
|
|
|
769 For example, if you distribute copies of the library, whether gratis
|
|
|
770 or for a fee, you must give the recipients all the rights that we gave
|
|
|
771 you. You must make sure that they, too, receive or can get the source
|
|
|
772 code. If you link a program with the library, you must provide
|
|
|
773 complete object files to the recipients so that they can relink them
|
|
|
774 with the library, after making changes to the library and recompiling
|
|
|
775 it. And you must show them these terms so they know their rights.
|
|
|
776
|
|
|
777 Our method of protecting your rights has two steps: (1) copyright
|
|
|
778 the library, and (2) offer you this license which gives you legal
|
|
|
779 permission to copy, distribute and/or modify the library.
|
|
|
780
|
|
|
781 Also, for each distributor's protection, we want to make certain
|
|
|
782 that everyone understands that there is no warranty for this free
|
|
|
783 library. If the library is modified by someone else and passed on, we
|
|
|
784 want its recipients to know that what they have is not the original
|
|
|
785 version, so that any problems introduced by others will not reflect on
|
|
|
786 the original authors' reputations.
|
|
|
787
|
|
|
788 Finally, any free program is threatened constantly by software
|
|
|
789 patents. We wish to avoid the danger that companies distributing free
|
|
|
790 software will individually obtain patent licenses, thus in effect
|
|
|
791 transforming the program into proprietary software. To prevent this,
|
|
|
792 we have made it clear that any patent must be licensed for everyone's
|
|
|
793 free use or not licensed at all.
|
|
|
794
|
|
|
795 Most GNU software, including some libraries, is covered by the ordinary
|
|
|
796 GNU General Public License, which was designed for utility programs. This
|
|
|
797 license, the GNU Library General Public License, applies to certain
|
|
|
798 designated libraries. This license is quite different from the ordinary
|
|
|
799 one; be sure to read it in full, and don't assume that anything in it is
|
|
|
800 the same as in the ordinary license.
|
|
|
801
|
|
|
802 The reason we have a separate public license for some libraries is that
|
|
|
803 they blur the distinction we usually make between modifying or adding to a
|
|
|
804 program and simply using it. Linking a program with a library, without
|
|
|
805 changing the library, is in some sense simply using the library, and is
|
|
|
806 analogous to running a utility program or application program. However, in
|
|
|
807 a textual and legal sense, the linked executable is a combined work, a
|
|
|
808 derivative of the original library, and the ordinary General Public License
|
|
|
809 treats it as such.
|
|
|
810
|
|
|
811 Because of this blurred distinction, using the ordinary General
|
|
|
812 Public License for libraries did not effectively promote software
|
|
|
813 sharing, because most developers did not use the libraries. We
|
|
|
814 concluded that weaker conditions might promote sharing better.
|
|
|
815
|
|
|
816 However, unrestricted linking of non-free programs would deprive the
|
|
|
817 users of those programs of all benefit from the free status of the
|
|
|
818 libraries themselves. This Library General Public License is intended to
|
|
|
819 permit developers of non-free programs to use free libraries, while
|
|
|
820 preserving your freedom as a user of such programs to change the free
|
|
|
821 libraries that are incorporated in them. (We have not seen how to achieve
|
|
|
822 this as regards changes in header files, but we have achieved it as regards
|
|
|
823 changes in the actual functions of the Library.) The hope is that this
|
|
|
824 will lead to faster development of free libraries.
|
|
|
825
|
|
|
826 The precise terms and conditions for copying, distribution and
|
|
|
827 modification follow. Pay close attention to the difference between a
|
|
|
828 "work based on the library" and a "work that uses the library". The
|
|
|
829 former contains code derived from the library, while the latter only
|
|
|
830 works together with the library.
|
|
|
831
|
|
|
832 Note that it is possible for a library to be covered by the ordinary
|
|
|
833 General Public License rather than by this special one.
|
|
|
834
|
|
|
835 GNU LIBRARY GENERAL PUBLIC LICENSE
|
|
|
836 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
|
|
|
837
|
|
|
838 0. This License Agreement applies to any software library which
|
|
|
839 contains a notice placed by the copyright holder or other authorized
|
|
|
840 party saying it may be distributed under the terms of this Library
|
|
|
841 General Public License (also called "this License"). Each licensee is
|
|
|
842 addressed as "you".
|
|
|
843
|
|
|
844 A "library" means a collection of software functions and/or data
|
|
|
845 prepared so as to be conveniently linked with application programs
|
|
|
846 (which use some of those functions and data) to form executables.
|
|
|
847
|
|
|
848 The "Library", below, refers to any such software library or work
|
|
|
849 which has been distributed under these terms. A "work based on the
|
|
|
850 Library" means either the Library or any derivative work under
|
|
|
851 copyright law: that is to say, a work containing the Library or a
|
|
|
852 portion of it, either verbatim or with modifications and/or translated
|
|
|
853 straightforwardly into another language. (Hereinafter, translation is
|
|
|
854 included without limitation in the term "modification".)
|
|
|
855
|
|
|
856 "Source code" for a work means the preferred form of the work for
|
|
|
857 making modifications to it. For a library, complete source code means
|
|
|
858 all the source code for all modules it contains, plus any associated
|
|
|
859 interface definition files, plus the scripts used to control compilation
|
|
|
860 and installation of the library.
|
|
|
861
|
|
|
862 Activities other than copying, distribution and modification are not
|
|
|
863 covered by this License; they are outside its scope. The act of
|
|
|
864 running a program using the Library is not restricted, and output from
|
|
|
865 such a program is covered only if its contents constitute a work based
|
|
|
866 on the Library (independent of the use of the Library in a tool for
|
|
|
867 writing it). Whether that is true depends on what the Library does
|
|
|
868 and what the program that uses the Library does.
|
|
|
869
|
|
|
870 1. You may copy and distribute verbatim copies of the Library's
|
|
|
871 complete source code as you receive it, in any medium, provided that
|
|
|
872 you conspicuously and appropriately publish on each copy an
|
|
|
873 appropriate copyright notice and disclaimer of warranty; keep intact
|
|
|
874 all the notices that refer to this License and to the absence of any
|
|
|
875 warranty; and distribute a copy of this License along with the
|
|
|
876 Library.
|
|
|
877
|
|
|
878 You may charge a fee for the physical act of transferring a copy,
|
|
|
879 and you may at your option offer warranty protection in exchange for a
|
|
|
880 fee.
|
|
|
881
|
|
|
882 2. You may modify your copy or copies of the Library or any portion
|
|
|
883 of it, thus forming a work based on the Library, and copy and
|
|
|
884 distribute such modifications or work under the terms of Section 1
|
|
|
885 above, provided that you also meet all of these conditions:
|
|
|
886
|
|
|
887 a) The modified work must itself be a software library.
|
|
|
888
|
|
|
889 b) You must cause the files modified to carry prominent notices
|
|
|
890 stating that you changed the files and the date of any change.
|
|
|
891
|
|
|
892 c) You must cause the whole of the work to be licensed at no
|
|
|
893 charge to all third parties under the terms of this License.
|
|
|
894
|
|
|
895 d) If a facility in the modified Library refers to a function or a
|
|
|
896 table of data to be supplied by an application program that uses
|
|
|
897 the facility, other than as an argument passed when the facility
|
|
|
898 is invoked, then you must make a good faith effort to ensure that,
|
|
|
899 in the event an application does not supply such function or
|
|
|
900 table, the facility still operates, and performs whatever part of
|
|
|
901 its purpose remains meaningful.
|
|
|
902
|
|
|
903 (For example, a function in a library to compute square roots has
|
|
|
904 a purpose that is entirely well-defined independent of the
|
|
|
905 application. Therefore, Subsection 2d requires that any
|
|
|
906 application-supplied function or table used by this function must
|
|
|
907 be optional: if the application does not supply it, the square
|
|
|
908 root function must still compute square roots.)
|
|
|
909
|
|
|
910 These requirements apply to the modified work as a whole. If
|
|
|
911 identifiable sections of that work are not derived from the Library,
|
|
|
912 and can be reasonably considered independent and separate works in
|
|
|
913 themselves, then this License, and its terms, do not apply to those
|
|
|
914 sections when you distribute them as separate works. But when you
|
|
|
915 distribute the same sections as part of a whole which is a work based
|
|
|
916 on the Library, the distribution of the whole must be on the terms of
|
|
|
917 this License, whose permissions for other licensees extend to the
|
|
|
918 entire whole, and thus to each and every part regardless of who wrote
|
|
|
919 it.
|
|
|
920
|
|
|
921 Thus, it is not the intent of this section to claim rights or contest
|
|
|
922 your rights to work written entirely by you; rather, the intent is to
|
|
|
923 exercise the right to control the distribution of derivative or
|
|
|
924 collective works based on the Library.
|
|
|
925
|
|
|
926 In addition, mere aggregation of another work not based on the Library
|
|
|
927 with the Library (or with a work based on the Library) on a volume of
|
|
|
928 a storage or distribution medium does not bring the other work under
|
|
|
929 the scope of this License.
|
|
|
930
|
|
|
931 3. You may opt to apply the terms of the ordinary GNU General Public
|
|
|
932 License instead of this License to a given copy of the Library. To do
|
|
|
933 this, you must alter all the notices that refer to this License, so
|
|
|
934 that they refer to the ordinary GNU General Public License, version 2,
|
|
|
935 instead of to this License. (If a newer version than version 2 of the
|
|
|
936 ordinary GNU General Public License has appeared, then you can specify
|
|
|
937 that version instead if you wish.) Do not make any other change in
|
|
|
938 these notices.
|
|
|
939
|
|
|
940 Once this change is made in a given copy, it is irreversible for
|
|
|
941 that copy, so the ordinary GNU General Public License applies to all
|
|
|
942 subsequent copies and derivative works made from that copy.
|
|
|
943
|
|
|
944 This option is useful when you wish to copy part of the code of
|
|
|
945 the Library into a program that is not a library.
|
|
|
946
|
|
|
947 4. You may copy and distribute the Library (or a portion or
|
|
|
948 derivative of it, under Section 2) in object code or executable form
|
|
|
949 under the terms of Sections 1 and 2 above provided that you accompany
|
|
|
950 it with the complete corresponding machine-readable source code, which
|
|
|
951 must be distributed under the terms of Sections 1 and 2 above on a
|
|
|
952 medium customarily used for software interchange.
|
|
|
953
|
|
|
954 If distribution of object code is made by offering access to copy
|
|
|
955 from a designated place, then offering equivalent access to copy the
|
|
|
956 source code from the same place satisfies the requirement to
|
|
|
957 distribute the source code, even though third parties are not
|
|
|
958 compelled to copy the source along with the object code.
|
|
|
959
|
|
|
960 5. A program that contains no derivative of any portion of the
|
|
|
961 Library, but is designed to work with the Library by being compiled or
|
|
|
962 linked with it, is called a "work that uses the Library". Such a
|
|
|
963 work, in isolation, is not a derivative work of the Library, and
|
|
|
964 therefore falls outside the scope of this License.
|
|
|
965
|
|
|
966 However, linking a "work that uses the Library" with the Library
|
|
|
967 creates an executable that is a derivative of the Library (because it
|
|
|
968 contains portions of the Library), rather than a "work that uses the
|
|
|
969 library". The executable is therefore covered by this License.
|
|
|
970 Section 6 states terms for distribution of such executables.
|
|
|
971
|
|
|
972 When a "work that uses the Library" uses material from a header file
|
|
|
973 that is part of the Library, the object code for the work may be a
|
|
|
974 derivative work of the Library even though the source code is not.
|
|
|
975 Whether this is true is especially significant if the work can be
|
|
|
976 linked without the Library, or if the work is itself a library. The
|
|
|
977 threshold for this to be true is not precisely defined by law.
|
|
|
978
|
|
|
979 If such an object file uses only numerical parameters, data
|
|
|
980 structure layouts and accessors, and small macros and small inline
|
|
|
981 functions (ten lines or less in length), then the use of the object
|
|
|
982 file is unrestricted, regardless of whether it is legally a derivative
|
|
|
983 work. (Executables containing this object code plus portions of the
|
|
|
984 Library will still fall under Section 6.)
|
|
|
985
|
|
|
986 Otherwise, if the work is a derivative of the Library, you may
|
|
|
987 distribute the object code for the work under the terms of Section 6.
|
|
|
988 Any executables containing that work also fall under Section 6,
|
|
|
989 whether or not they are linked directly with the Library itself.
|
|
|
990
|
|
|
991 6. As an exception to the Sections above, you may also compile or
|
|
|
992 link a "work that uses the Library" with the Library to produce a
|
|
|
993 work containing portions of the Library, and distribute that work
|
|
|
994 under terms of your choice, provided that the terms permit
|
|
|
995 modification of the work for the customer's own use and reverse
|
|
|
996 engineering for debugging such modifications.
|
|
|
997
|
|
|
998 You must give prominent notice with each copy of the work that the
|
|
|
999 Library is used in it and that the Library and its use are covered by
|
|
|
1000 this License. You must supply a copy of this License. If the work
|
|
|
1001 during execution displays copyright notices, you must include the
|
|
|
1002 copyright notice for the Library among them, as well as a reference
|
|
|
1003 directing the user to the copy of this License. Also, you must do one
|
|
|
1004 of these things:
|
|
|
1005
|
|
|
1006 a) Accompany the work with the complete corresponding
|
|
|
1007 machine-readable source code for the Library including whatever
|
|
|
1008 changes were used in the work (which must be distributed under
|
|
|
1009 Sections 1 and 2 above); and, if the work is an executable linked
|
|
|
1010 with the Library, with the complete machine-readable "work that
|
|
|
1011 uses the Library", as object code and/or source code, so that the
|
|
|
1012 user can modify the Library and then relink to produce a modified
|
|
|
1013 executable containing the modified Library. (It is understood
|
|
|
1014 that the user who changes the contents of definitions files in the
|
|
|
1015 Library will not necessarily be able to recompile the application
|
|
|
1016 to use the modified definitions.)
|
|
|
1017
|
|
|
1018 b) Accompany the work with a written offer, valid for at
|
|
|
1019 least three years, to give the same user the materials
|
|
|
1020 specified in Subsection 6a, above, for a charge no more
|
|
|
1021 than the cost of performing this distribution.
|
|
|
1022
|
|
|
1023 c) If distribution of the work is made by offering access to copy
|
|
|
1024 from a designated place, offer equivalent access to copy the above
|
|
|
1025 specified materials from the same place.
|
|
|
1026
|
|
|
1027 d) Verify that the user has already received a copy of these
|
|
|
1028 materials or that you have already sent this user a copy.
|
|
|
1029
|
|
|
1030 For an executable, the required form of the "work that uses the
|
|
|
1031 Library" must include any data and utility programs needed for
|
|
|
1032 reproducing the executable from it. However, as a special exception,
|
|
|
1033 the source code distributed need not include anything that is normally
|
|
|
1034 distributed (in either source or binary form) with the major
|
|
|
1035 components (compiler, kernel, and so on) of the operating system on
|
|
|
1036 which the executable runs, unless that component itself accompanies
|
|
|
1037 the executable.
|
|
|
1038
|
|
|
1039 It may happen that this requirement contradicts the license
|
|
|
1040 restrictions of other proprietary libraries that do not normally
|
|
|
1041 accompany the operating system. Such a contradiction means you cannot
|
|
|
1042 use both them and the Library together in an executable that you
|
|
|
1043 distribute.
|
|
|
1044
|
|
|
1045 7. You may place library facilities that are a work based on the
|
|
|
1046 Library side-by-side in a single library together with other library
|
|
|
1047 facilities not covered by this License, and distribute such a combined
|
|
|
1048 library, provided that the separate distribution of the work based on
|
|
|
1049 the Library and of the other library facilities is otherwise
|
|
|
1050 permitted, and provided that you do these two things:
|
|
|
1051
|
|
|
1052 a) Accompany the combined library with a copy of the same work
|
|
|
1053 based on the Library, uncombined with any other library
|
|
|
1054 facilities. This must be distributed under the terms of the
|
|
|
1055 Sections above.
|
|
|
1056
|
|
|
1057 b) Give prominent notice with the combined library of the fact
|
|
|
1058 that part of it is a work based on the Library, and explaining
|
|
|
1059 where to find the accompanying uncombined form of the same work.
|
|
|
1060
|
|
|
1061 8. You may not copy, modify, sublicense, link with, or distribute
|
|
|
1062 the Library except as expressly provided under this License. Any
|
|
|
1063 attempt otherwise to copy, modify, sublicense, link with, or
|
|
|
1064 distribute the Library is void, and will automatically terminate your
|
|
|
1065 rights under this License. However, parties who have received copies,
|
|
|
1066 or rights, from you under this License will not have their licenses
|
|
|
1067 terminated so long as such parties remain in full compliance.
|
|
|
1068
|
|
|
1069 9. You are not required to accept this License, since you have not
|
|
|
1070 signed it. However, nothing else grants you permission to modify or
|
|
|
1071 distribute the Library or its derivative works. These actions are
|
|
|
1072 prohibited by law if you do not accept this License. Therefore, by
|
|
|
1073 modifying or distributing the Library (or any work based on the
|
|
|
1074 Library), you indicate your acceptance of this License to do so, and
|
|
|
1075 all its terms and conditions for copying, distributing or modifying
|
|
|
1076 the Library or works based on it.
|
|
|
1077
|
|
|
1078 10. Each time you redistribute the Library (or any work based on the
|
|
|
1079 Library), the recipient automatically receives a license from the
|
|
|
1080 original licensor to copy, distribute, link with or modify the Library
|
|
|
1081 subject to these terms and conditions. You may not impose any further
|
|
|
1082 restrictions on the recipients' exercise of the rights granted herein.
|
|
|
1083 You are not responsible for enforcing compliance by third parties to
|
|
|
1084 this License.
|
|
|
1085
|
|
|
1086 11. If, as a consequence of a court judgment or allegation of patent
|
|
|
1087 infringement or for any other reason (not limited to patent issues),
|
|
|
1088 conditions are imposed on you (whether by court order, agreement or
|
|
|
1089 otherwise) that contradict the conditions of this License, they do not
|
|
|
1090 excuse you from the conditions of this License. If you cannot
|
|
|
1091 distribute so as to satisfy simultaneously your obligations under this
|
|
|
1092 License and any other pertinent obligations, then as a consequence you
|
|
|
1093 may not distribute the Library at all. For example, if a patent
|
|
|
1094 license would not permit royalty-free redistribution of the Library by
|
|
|
1095 all those who receive copies directly or indirectly through you, then
|
|
|
1096 the only way you could satisfy both it and this License would be to
|
|
|
1097 refrain entirely from distribution of the Library.
|
|
|
1098
|
|
|
1099 If any portion of this section is held invalid or unenforceable under any
|
|
|
1100 particular circumstance, the balance of the section is intended to apply,
|
|
|
1101 and the section as a whole is intended to apply in other circumstances.
|
|
|
1102
|
|
|
1103 It is not the purpose of this section to induce you to infringe any
|
|
|
1104 patents or other property right claims or to contest validity of any
|
|
|
1105 such claims; this section has the sole purpose of protecting the
|
|
|
1106 integrity of the free software distribution system which is
|
|
|
1107 implemented by public license practices. Many people have made
|
|
|
1108 generous contributions to the wide range of software distributed
|
|
|
1109 through that system in reliance on consistent application of that
|
|
|
1110 system; it is up to the author/donor to decide if he or she is willing
|
|
|
1111 to distribute software through any other system and a licensee cannot
|
|
|
1112 impose that choice.
|
|
|
1113
|
|
|
1114 This section is intended to make thoroughly clear what is believed to
|
|
|
1115 be a consequence of the rest of this License.
|
|
|
1116
|
|
|
1117 12. If the distribution and/or use of the Library is restricted in
|
|
|
1118 certain countries either by patents or by copyrighted interfaces, the
|
|
|
1119 original copyright holder who places the Library under this License may add
|
|
|
1120 an explicit geographical distribution limitation excluding those countries,
|
|
|
1121 so that distribution is permitted only in or among countries not thus
|
|
|
1122 excluded. In such case, this License incorporates the limitation as if
|
|
|
1123 written in the body of this License.
|
|
|
1124
|
|
|
1125 13. The Free Software Foundation may publish revised and/or new
|
|
|
1126 versions of the Library General Public License from time to time.
|
|
|
1127 Such new versions will be similar in spirit to the present version,
|
|
|
1128 but may differ in detail to address new problems or concerns.
|
|
|
1129
|
|
|
1130 Each version is given a distinguishing version number. If the Library
|
|
|
1131 specifies a version number of this License which applies to it and
|
|
|
1132 "any later version", you have the option of following the terms and
|
|
|
1133 conditions either of that version or of any later version published by
|
|
|
1134 the Free Software Foundation. If the Library does not specify a
|
|
|
1135 license version number, you may choose any version ever published by
|
|
|
1136 the Free Software Foundation.
|
|
|
1137
|
|
|
1138 14. If you wish to incorporate parts of the Library into other free
|
|
|
1139 programs whose distribution conditions are incompatible with these,
|
|
|
1140 write to the author to ask for permission. For software which is
|
|
|
1141 copyrighted by the Free Software Foundation, write to the Free
|
|
|
1142 Software Foundation; we sometimes make exceptions for this. Our
|
|
|
1143 decision will be guided by the two goals of preserving the free status
|
|
|
1144 of all derivatives of our free software and of promoting the sharing
|
|
|
1145 and reuse of software generally.
|
|
|
1146
|
|
|
1147 NO WARRANTY
|
|
|
1148
|
|
|
1149 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
|
|
|
1150 WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
|
|
|
1151 EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
|
|
|
1152 OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
|
|
|
1153 KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
|
|
|
1154 IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
|
|
|
1155 PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
|
|
|
1156 LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
|
|
|
1157 THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
|
|
|
1158
|
|
|
1159 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
|
|
|
1160 WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
|
|
|
1161 AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
|
|
|
1162 FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
|
|
|
1163 CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
|
|
|
1164 LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
|
|
|
1165 RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
|
|
|
1166 FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
|
|
|
1167 SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
|
|
|
1168 DAMAGES.

1178
|
|
|
1179 Copyright (C) 1989, 1991 Free Software Foundation, Inc.
|
|
|
1180 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
|
|
|
1181 Everyone is permitted to copy and distribute verbatim copies
|
|
|
1182 of this license document, but changing it is not allowed.
|
|
|
1183
|
|
|
1184 Preamble
|
|
|
1185
|
|
|
1186 The licenses for most software are designed to take away your
|
|
|
1187 freedom to share and change it. By contrast, the GNU General Public
|
|
|
1188 License is intended to guarantee your freedom to share and change free
|
|
|
1189 software--to make sure the software is free for all its users. This
|
|
|
1190 General Public License applies to most of the Free Software
|
|
|
1191 Foundation's software and to any other program whose authors commit to
|
|
|
1192 using it. (Some other Free Software Foundation software is covered by
|
|
|
1193 the GNU Library General Public License instead.) You can apply it to
|
|
|
1194 your programs, too.
|
|
|
1195
|
|
|
1196 When we speak of free software, we are referring to freedom, not
|
|
|
1197 price. Our General Public Licenses are designed to make sure that you
|
|
|
1198 have the freedom to distribute copies of free software (and charge for
|
|
|
1199 this service if you wish), that you receive source code or can get it
|
|
|
1200 if you want it, that you can change the software or use pieces of it
|
|
|
1201 in new free programs; and that you know you can do these things.
|
|
|
1202
|
|
|
1203 To protect your rights, we need to make restrictions that forbid
|
|
|
1204 anyone to deny you these rights or to ask you to surrender the rights.
|
|
|
1205 These restrictions translate to certain responsibilities for you if you
|
|
|
1206 distribute copies of the software, or if you modify it.
|
|
|
1207
|
|
|
1208 For example, if you distribute copies of such a program, whether
|
|
|
1209 gratis or for a fee, you must give the recipients all the rights that
|
|
|
1210 you have. You must make sure that they, too, receive or can get the
|
|
|
1211 source code. And you must show them these terms so they know their
|
|
|
1212 rights.
|
|
|
1213
|
|
|
1214 We protect your rights with two steps: (1) copyright the software, and
|
|
|
1215 (2) offer you this license which gives you legal permission to copy,
|
|
|
1216 distribute and/or modify the software.
|
|
|
1217
|
|
|
1218 Also, for each author's protection and ours, we want to make certain
|
|
|
1219 that everyone understands that there is no warranty for this free
|
|
|
1220 software. If the software is modified by someone else and passed on, we
|
|
|
1221 want its recipients to know that what they have is not the original, so
|
|
|
1222 that any problems introduced by others will not reflect on the original
|
|
|
1223 authors' reputations.
|
|
|
1224
|
|
|
1225 Finally, any free program is threatened constantly by software
|
|
|
1226 patents. We wish to avoid the danger that redistributors of a free
|
|
|
1227 program will individually obtain patent licenses, in effect making the
|
|
|
1228 program proprietary. To prevent this, we have made it clear that any
|
|
|
1229 patent must be licensed for everyone's free use or not licensed at all.
|
|
|
1230
|
|
|
1231 The precise terms and conditions for copying, distribution and
|
|
|
1232 modification follow.
|
|
|
1233
|
|
|
1234 GNU GENERAL PUBLIC LICENSE
|
|
|
1235 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
|
|
|
1236
|
|
|
1237 0. This License applies to any program or other work which contains
|
|
|
1238 a notice placed by the copyright holder saying it may be distributed
|
|
|
1239 under the terms of this General Public License. The "Program", below,
|
|
|
1240 refers to any such program or work, and a "work based on the Program"
|
|
|
1241 means either the Program or any derivative work under copyright law:
|
|
|
1242 that is to say, a work containing the Program or a portion of it,
|
|
|
1243 either verbatim or with modifications and/or translated into another
|
|
|
1244 language. (Hereinafter, translation is included without limitation in
|
|
|
1245 the term "modification".) Each licensee is addressed as "you".
|
|
|
1246
|
|
|
1247 Activities other than copying, distribution and modification are not
|
|
|
1248 covered by this License; they are outside its scope. The act of
|
|
|
1249 running the Program is not restricted, and the output from the Program
|
|
|
1250 is covered only if its contents constitute a work based on the
|
|
|
1251 Program (independent of having been made by running the Program).
|
|
|
1252 Whether that is true depends on what the Program does.
|
|
|
1253
|
|
|
1254 1. You may copy and distribute verbatim copies of the Program's
|
|
|
1255 source code as you receive it, in any medium, provided that you
|
|
|
1256 conspicuously and appropriately publish on each copy an appropriate
|
|
|
1257 copyright notice and disclaimer of warranty; keep intact all the
|
|
|
1258 notices that refer to this License and to the absence of any warranty;
|
|
|
1259 and give any other recipients of the Program a copy of this License
|
|
|
1260 along with the Program.
|
|
|
1261
|
|
|
1262 You may charge a fee for the physical act of transferring a copy, and
|
|
|
1263 you may at your option offer warranty protection in exchange for a fee.
|
|
|
1264
|
|
|
1265 2. You may modify your copy or copies of the Program or any portion
|
|
|
1266 of it, thus forming a work based on the Program, and copy and
|
|
|
1267 distribute such modifications or work under the terms of Section 1
|
|
|
1268 above, provided that you also meet all of these conditions:
|
|
|
1269
|
|
|
1270 a) You must cause the modified files to carry prominent notices
|
|
|
1271 stating that you changed the files and the date of any change.
|
|
|
1272
|
|
|
1273 b) You must cause any work that you distribute or publish, that in
|
|
|
1274 whole or in part contains or is derived from the Program or any
|
|
|
1275 part thereof, to be licensed as a whole at no charge to all third
|
|
|
1276 parties under the terms of this License.
|
|
|
1277
|
|
|
1278 c) If the modified program normally reads commands interactively
|
|
|
1279 when run, you must cause it, when started running for such
|
|
|
1280 interactive use in the most ordinary way, to print or display an
|
|
|
1281 announcement including an appropriate copyright notice and a
|
|
|
1282 notice that there is no warranty (or else, saying that you provide
|
|
|
1283 a warranty) and that users may redistribute the program under
|
|
|
1284 these conditions, and telling the user how to view a copy of this
|
|
|
1285 License. (Exception: if the Program itself is interactive but
|
|
|
1286 does not normally print such an announcement, your work based on
|
|
|
1287 the Program is not required to print an announcement.)
|
|
|
1288
|
|
|
1289 These requirements apply to the modified work as a whole. If
|
|
|
1290 identifiable sections of that work are not derived from the Program,
|
|
|
1291 and can be reasonably considered independent and separate works in
|
|
|
1292 themselves, then this License, and its terms, do not apply to those
|
|
|
1293 sections when you distribute them as separate works. But when you
|
|
|
1294 distribute the same sections as part of a whole which is a work based
|
|
|
1295 on the Program, the distribution of the whole must be on the terms of
|
|
|
1296 this License, whose permissions for other licensees extend to the
|
|
|
1297 entire whole, and thus to each and every part regardless of who wrote it.
|

|
1298
|
|
|
1299 Thus, it is not the intent of this section to claim rights or contest
|
|
|
1300 your rights to work written entirely by you; rather, the intent is to
|
|
|
1301 exercise the right to control the distribution of derivative or
|
|
|
1302 collective works based on the Program.
|
|
|
1303
|
|
|
1304 In addition, mere aggregation of another work not based on the Program
|
|
|
1305 with the Program (or with a work based on the Program) on a volume of
|
|
|
1306 a storage or distribution medium does not bring the other work under
|
|
|
1307 the scope of this License.
|
|
|
1308
|
|
|
1309 3. You may copy and distribute the Program (or a work based on it,
|
|
|
1310 under Section 2) in object code or executable form under the terms of
|
|
|
1311 Sections 1 and 2 above provided that you also do one of the following:
|
|
|
1312
|
|
|
1313 a) Accompany it with the complete corresponding machine-readable
|
|
|
1314 source code, which must be distributed under the terms of Sections
|
|
|
1315 1 and 2 above on a medium customarily used for software interchange; or,
|
|
|
1316
|
|
|
1317 b) Accompany it with a written offer, valid for at least three
|
|
|
1318 years, to give any third party, for a charge no more than your
|
|
|
1319 cost of physically performing source distribution, a complete
|
|
|
1320 machine-readable copy of the corresponding source code, to be
|
|
|
1321 distributed under the terms of Sections 1 and 2 above on a medium
|
|
|
1322 customarily used for software interchange; or,
|
|
|
1323
|
|
|
1324 c) Accompany it with the information you received as to the offer
|
|
|
1325 to distribute corresponding source code. (This alternative is
|
|
|
1326 allowed only for noncommercial distribution and only if you
|
|
|
1327 received the program in object code or executable form with such
|
|
|
1328 an offer, in accord with Subsection b above.)
|
|
|
1329
|
|
|
1330 The source code for a work means the preferred form of the work for
|
|
|
1331 making modifications to it. For an executable work, complete source
|
|
|
1332 code means all the source code for all modules it contains, plus any
|
|
|
1333 associated interface definition files, plus the scripts used to
|
|
|
1334 control compilation and installation of the executable. However, as a
|
|
|
1335 special exception, the source code distributed need not include
|
|
|
1336 anything that is normally distributed (in either source or binary
|
|
|
1337 form) with the major components (compiler, kernel, and so on) of the
|
|
|
1338 operating system on which the executable runs, unless that component
|
|
|
1339 itself accompanies the executable.
|
|
|
1340
|
|
|
1341 If distribution of executable or object code is made by offering
|
|
|
1342 access to copy from a designated place, then offering equivalent
|
|
|
1343 access to copy the source code from the same place counts as
|
|
|
1344 distribution of the source code, even though third parties are not
|
|
|
1345 compelled to copy the source along with the object code.
|
|
|
1346
|
|
|
1347 4. You may not copy, modify, sublicense, or distribute the Program
|
|
|
1348 except as expressly provided under this License. Any attempt
|
|
|
1349 otherwise to copy, modify, sublicense or distribute the Program is
|
|
|
1350 void, and will automatically terminate your rights under this License.
|
|
|
1351 However, parties who have received copies, or rights, from you under
|
|
|
1352 this License will not have their licenses terminated so long as such
|
|
|
1353 parties remain in full compliance.
|
|
|
1354
|
|
|
1355 5. You are not required to accept this License, since you have not
|
|
|
1356 signed it. However, nothing else grants you permission to modify or
|
|
|
1357 distribute the Program or its derivative works. These actions are
|
|
|
1358 prohibited by law if you do not accept this License. Therefore, by
|
|
|
1359 modifying or distributing the Program (or any work based on the
|
|
|
1360 Program), you indicate your acceptance of this License to do so, and
|
|
|
1361 all its terms and conditions for copying, distributing or modifying
|
|
|
1362 the Program or works based on it.
|
|
|
1363
|
|
|
1364 6. Each time you redistribute the Program (or any work based on the
|
|
|
1365 Program), the recipient automatically receives a license from the
|
|
|
1366 original licensor to copy, distribute or modify the Program subject to
|
|
|
1367 these terms and conditions. You may not impose any further
|
|
|
1368 restrictions on the recipients' exercise of the rights granted herein.
|
|
|
1369 You are not responsible for enforcing compliance by third parties to
|
|
|
1370 this License.
|
|
|
1371
|
|
|
1372 7. If, as a consequence of a court judgment or allegation of patent
|
|
|
1373 infringement or for any other reason (not limited to patent issues),
|
|
|
1374 conditions are imposed on you (whether by court order, agreement or
|
|
|
1375 otherwise) that contradict the conditions of this License, they do not
|
|
|
1376 excuse you from the conditions of this License. If you cannot
|
|
|
1377 distribute so as to satisfy simultaneously your obligations under this
|
|
|
1378 License and any other pertinent obligations, then as a consequence you
|
|
|
1379 may not distribute the Program at all. For example, if a patent
|
|
|
1380 license would not permit royalty-free redistribution of the Program by
|
|
|
1381 all those who receive copies directly or indirectly through you, then
|
|
|
1382 the only way you could satisfy both it and this License would be to
|
|
|
1383 refrain entirely from distribution of the Program.
|
|
|
1384
|
|
|
1385 If any portion of this section is held invalid or unenforceable under
|
|
|
1386 any particular circumstance, the balance of the section is intended to
|
|
|
1387 apply and the section as a whole is intended to apply in other
|
|
|
1388 circumstances.
|
|
|
1389
|
|
|
1390 It is not the purpose of this section to induce you to infringe any
|
|
|
1391 patents or other property right claims or to contest validity of any
|
|
|
1392 such claims; this section has the sole purpose of protecting the
|
|
|
1393 integrity of the free software distribution system, which is
|
|
|
1394 implemented by public license practices. Many people have made
|
|
|
1395 generous contributions to the wide range of software distributed
|
|
|
1396 through that system in reliance on consistent application of that
|
|
|
1397 system; it is up to the author/donor to decide if he or she is willing
|
|
|
1398 to distribute software through any other system and a licensee cannot
|
|
|
1399 impose that choice.
|
|
|
1400
|
|
|
1401 This section is intended to make thoroughly clear what is believed to
|
|
|
1402 be a consequence of the rest of this License.
|
|
|
1403
|
|
|
1404 8. If the distribution and/or use of the Program is restricted in
|
|
|
1405 certain countries either by patents or by copyrighted interfaces, the
|
|
|
1406 original copyright holder who places the Program under this License
|
|
|
1407 may add an explicit geographical distribution limitation excluding
|
|
|
1408 those countries, so that distribution is permitted only in or among
|
|
|
1409 countries not thus excluded. In such case, this License incorporates
|
|
|
1410 the limitation as if written in the body of this License.
|
|
|
1411
|
|
|
1412 9. The Free Software Foundation may publish revised and/or new versions
|
|
|
1413 of the General Public License from time to time. Such new versions will
|
|
|
1414 be similar in spirit to the present version, but may differ in detail to
|
|
|
1415 address new problems or concerns.
|
|
|
1416
|
|
|
1417 Each version is given a distinguishing version number. If the Program
|
|
|
1418 specifies a version number of this License which applies to it and "any
|
|
|
1419 later version", you have the option of following the terms and conditions
|
|
|
1420 either of that version or of any later version published by the Free
|
|
|
1421 Software Foundation. If the Program does not specify a version number of
|
|
|
1422 this License, you may choose any version ever published by the Free Software
|
|
|
1423 Foundation.
|
|
|
1424
|
|
|
1425 10. If you wish to incorporate parts of the Program into other free
|
|
|
1426 programs whose distribution conditions are different, write to the author
|
|
|
1427 to ask for permission. For software which is copyrighted by the Free
|
|
|
1428 Software Foundation, write to the Free Software Foundation; we sometimes
|
|
|
1429 make exceptions for this. Our decision will be guided by the two goals
|
|
|
1430 of preserving the free status of all derivatives of our free software and
|
|
|
1431 of promoting the sharing and reuse of software generally.
|
|
|
1432
|
|
|
1433 NO WARRANTY
|
|
|
1434
|
|
|
1435 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
|
|
|
1436 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
|
|
|
1437 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
|
|
|
1438 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
|
|
|
1439 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
|
|
|
1440 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
|
|
|
1441 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
|
|
|
1442 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
|
|
|
1443 REPAIR OR CORRECTION.
|
|
|
1444
|
|
|
1445 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
|
|
|
1446 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
|
|
|
1447 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
|
|
|
1448 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
|
|
|
1449 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
|
|
|
1450 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
|
|
|
1451 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
|
|
|
1452 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
|
|
|
1453 POSSIBILITY OF SUCH DAMAGES.
|
|
|
1454
|
|
|
1455 END OF TERMS AND CONDITIONS
|
|
|
1456
|
|
|
1457 How to Apply These Terms to Your New Programs
|
|
|
1458
|
|
|
1459 If you develop a new program, and you want it to be of the greatest
|
|
|
1460 possible use to the public, the best way to achieve this is to make it
|
|
|
1461 free software which everyone can redistribute and change under these terms.
|
|
|
1462
|
|
|
1463 To do so, attach the following notices to the program. It is safest
|
|
|
1464 to attach them to the start of each source file to most effectively
|
|
|
1465 convey the exclusion of warranty; and each file should have at least
|
|
|
1466 the "copyright" line and a pointer to where the full notice is found.
|
|
|
1467
|
|
|
1468 <one line to give the program's name and a brief idea of what it does.>
|
|
|

1471 This program is free software; you can redistribute it and/or modify
|

1472 it under the terms of the GNU General Public License as published by

|
|

|
|
1475
|
|
|
1476 This program is distributed in the hope that it will be useful,
|
|
|
1477 but WITHOUT ANY WARRANTY; without even the implied warranty of
|
|
|
1478 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
|
|
|
1479 GNU General Public License for more details.
|
|
|
1480
|
|
|
1481 You should have received a copy of the GNU General Public License
|
|
|
1482 along with this program; if not, write to the Free Software
|

1483 Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
|
|
|
1484
|
|
|
1485
|
|
|
1486 Also add information on how to contact you by electronic and paper mail.
|
|
|
1487
|
|
|
1488 If the program is interactive, make it output a short notice like this
|
|
|
1489 when it starts in an interactive mode:
|
|
|
1490
|
|
|
1491 Gnomovision version 69, Copyright (C) year name of author
|
|
|
1492 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
|
|
|
1493 This is free software, and you are welcome to redistribute it
|
|
|
1494 under certain conditions; type `show c' for details.
|
|
|
1495
|
|
|
1496 The hypothetical commands `show w' and `show c' should show the appropriate
|
|
|
1497 parts of the General Public License. Of course, the commands you use may
|
|
|
1498 be called something other than `show w' and `show c'; they could even be
|
|
|
1499 mouse-clicks or menu items--whatever suits your program.
|
|
|
1500
|
|
|
1501 You should also get your employer (if you work as a programmer) or your
|
|
|
1502 school, if any, to sign a "copyright disclaimer" for the program, if
|
|
|
1503 necessary. Here is a sample; alter the names:

1511 This General Public License does not permit incorporating your program into
|
|
|
1512 proprietary programs. If your program is a subroutine library, you may
|
|
|
1513 consider it more useful to permit linking proprietary applications with the
|
|
|
1514 library. If this is what you want to do, use the GNU Library General
|
|
|
1515 Public License instead of this License.
