5 1.1 skrll Everyone is permitted to copy and distribute verbatim copies
6 1.1 skrll of this license document, but changing it is not allowed.
7 1.1 skrll
8 1.1 skrll Preamble
9 1.1 skrll
10 1.1 skrll The GNU General Public License is a free, copyleft license for
11 1.1 skrll software and other kinds of works.
12 1.1 skrll
13 1.1 skrll The licenses for most software and other practical works are designed
14 1.1 skrll to take away your freedom to share and change the works. By contrast,
15 1.1 skrll the GNU General Public License is intended to guarantee your freedom to
16 1.1 skrll share and change all versions of a program--to make sure it remains free
17 1.1 skrll software for all its users. We, the Free Software Foundation, use the
18 1.1 skrll GNU General Public License for most of our software; it applies also to
19 1.1 skrll any other work released this way by its authors. You can apply it to
20 1.1 skrll your programs, too.
21 1.1 skrll
22 1.1 skrll When we speak of free software, we are referring to freedom, not
23 1.1 skrll price. Our General Public Licenses are designed to make sure that you
24 1.1 skrll have the freedom to distribute copies of free software (and charge for
25 1.1 skrll them if you wish), that you receive source code or can get it if you
26 1.1 skrll want it, that you can change the software or use pieces of it in new
27 1.1 skrll free programs, and that you know you can do these things.
28 1.1 skrll
29 1.1 skrll To protect your rights, we need to prevent others from denying you
30 1.1 skrll these rights or asking you to surrender the rights. Therefore, you have
31 1.1 skrll certain responsibilities if you distribute copies of the software, or if
32 1.1 skrll you modify it: responsibilities to respect the freedom of others.
33 1.1 skrll
34 1.1 skrll For example, if you distribute copies of such a program, whether
35 1.1 skrll gratis or for a fee, you must pass on to the recipients the same
36 1.1 skrll freedoms that you received. You must make sure that they, too, receive
37 1.1 skrll or can get the source code. And you must show them these terms so they
38 1.1 skrll know their rights.
39 1.1 skrll
40 1.1 skrll Developers that use the GNU GPL protect your rights with two steps:
41 1.1 skrll (1) assert copyright on the software, and (2) offer you this License
42 1.1 skrll giving you legal permission to copy, distribute and/or modify it.
43 1.1 skrll
44 1.1 skrll For the developers' and authors' protection, the GPL clearly explains
45 1.1 skrll that there is no warranty for this free software. For both users' and
46 1.1 skrll authors' sake, the GPL requires that modified versions be marked as
47 1.1 skrll changed, so that their problems will not be attributed erroneously to
48 1.1 skrll authors of previous versions.
49 1.1 skrll
50 1.1 skrll Some devices are designed to deny users access to install or run
51 1.1 skrll modified versions of the software inside them, although the manufacturer
52 1.1 skrll can do so. This is fundamentally incompatible with the aim of
53 1.1 skrll protecting users' freedom to change the software. The systematic
54 1.1 skrll pattern of such abuse occurs in the area of products for individuals to
55 1.1 skrll use, which is precisely where it is most unacceptable. Therefore, we
56 1.1 skrll have designed this version of the GPL to prohibit the practice for those
57 1.1 skrll products. If such problems arise substantially in other domains, we
58 1.1 skrll stand ready to extend this provision to those domains in future versions
59 1.1 skrll of the GPL, as needed to protect the freedom of users.
60 1.1 skrll
61 1.1 skrll Finally, every program is threatened constantly by software patents.
62 1.1 skrll States should not allow patents to restrict development and use of
63 1.1 skrll software on general-purpose computers, but in those that do, we wish to
64 1.1 skrll avoid the special danger that patents applied to a free program could
65 1.1 skrll make it effectively proprietary. To prevent this, the GPL assures that
66 1.1 skrll patents cannot be used to render the program non-free.
67 1.1 skrll
68 1.1 skrll The precise terms and conditions for copying, distribution and
69 1.1 skrll modification follow.
70 1.1 skrll
71 1.1 skrll TERMS AND CONDITIONS
72 1.1 skrll
73 1.1 skrll 0. Definitions.
74 1.1 skrll
75 1.1 skrll "This License" refers to version 3 of the GNU General Public License.
76 1.1 skrll
77 1.1 skrll "Copyright" also means copyright-like laws that apply to other kinds of
78 1.1 skrll works, such as semiconductor masks.
79 1.1 skrll
80 1.1 skrll "The Program" refers to any copyrightable work licensed under this
81 1.1 skrll License. Each licensee is addressed as "you". "Licensees" and
82 1.1 skrll "recipients" may be individuals or organizations.
83 1.1 skrll
84 1.1 skrll To "modify" a work means to copy from or adapt all or part of the work
85 1.1 skrll in a fashion requiring copyright permission, other than the making of an
86 1.1 skrll exact copy. The resulting work is called a "modified version" of the
87 1.1 skrll earlier work or a work "based on" the earlier work.
88 1.1 skrll
89 1.1 skrll A "covered work" means either the unmodified Program or a work based
90 1.1 skrll on the Program.
91 1.1 skrll
92 1.1 skrll To "propagate" a work means to do anything with it that, without
93 1.1 skrll permission, would make you directly or secondarily liable for
94 1.1 skrll infringement under applicable copyright law, except executing it on a
95 1.1 skrll computer or modifying a private copy. Propagation includes copying,
96 1.1 skrll distribution (with or without modification), making available to the
97 1.1 skrll public, and in some countries other activities as well.
98 1.1 skrll
99 1.1 skrll To "convey" a work means any kind of propagation that enables other
100 1.1 skrll parties to make or receive copies. Mere interaction with a user through
101 1.1 skrll a computer network, with no transfer of a copy, is not conveying.
102 1.1 skrll
103 1.1 skrll An interactive user interface displays "Appropriate Legal Notices"
104 1.1 skrll to the extent that it includes a convenient and prominently visible
105 1.1 skrll feature that (1) displays an appropriate copyright notice, and (2)
106 1.1 skrll tells the user that there is no warranty for the work (except to the
107 1.1 skrll extent that warranties are provided), that licensees may convey the
108 1.1 skrll work under this License, and how to view a copy of this License. If
109 1.1 skrll the interface presents a list of user commands or options, such as a
110 1.1 skrll menu, a prominent item in the list meets this criterion.
111 1.1 skrll
112 1.1 skrll 1. Source Code.
113 1.1 skrll
114 1.1 skrll The "source code" for a work means the preferred form of the work
115 1.1 skrll for making modifications to it. "Object code" means any non-source
116 1.1 skrll form of a work.
117 1.1 skrll
118 1.1 skrll A "Standard Interface" means an interface that either is an official
119 1.1 skrll standard defined by a recognized standards body, or, in the case of
120 1.1 skrll interfaces specified for a particular programming language, one that
121 1.1 skrll is widely used among developers working in that language.
122 1.1 skrll
123 1.1 skrll The "System Libraries" of an executable work include anything, other
124 1.1 skrll than the work as a whole, that (a) is included in the normal form of
125 1.1 skrll packaging a Major Component, but which is not part of that Major
126 1.1 skrll Component, and (b) serves only to enable use of the work with that
127 1.1 skrll Major Component, or to implement a Standard Interface for which an
128 1.1 skrll implementation is available to the public in source code form. A
129 1.1 skrll "Major Component", in this context, means a major essential component
130 1.1 skrll (kernel, window system, and so on) of the specific operating system
131 1.1 skrll (if any) on which the executable work runs, or a compiler used to
132 1.1 skrll produce the work, or an object code interpreter used to run it.
133 1.1 skrll
134 1.1 skrll The "Corresponding Source" for a work in object code form means all
135 1.1 skrll the source code needed to generate, install, and (for an executable
136 1.1 skrll work) run the object code and to modify the work, including scripts to
137 1.1 skrll control those activities. However, it does not include the work's
138 1.1 skrll System Libraries, or general-purpose tools or generally available free
139 1.1 skrll programs which are used unmodified in performing those activities but
140 1.1 skrll which are not part of the work. For example, Corresponding Source
141 1.1 skrll includes interface definition files associated with source files for
142 1.1 skrll the work, and the source code for shared libraries and dynamically
143 1.1 skrll linked subprograms that the work is specifically designed to require,
144 1.1 skrll such as by intimate data communication or control flow between those
145 1.1 skrll subprograms and other parts of the work.
146 1.1 skrll
147 1.1 skrll The Corresponding Source need not include anything that users
148 1.1 skrll can regenerate automatically from other parts of the Corresponding
149 1.1 skrll Source.
150 1.1 skrll
151 1.1 skrll The Corresponding Source for a work in source code form is that
152 1.1 skrll same work.
153 1.1 skrll
154 1.1 skrll 2. Basic Permissions.
155 1.1 skrll
156 1.1 skrll All rights granted under this License are granted for the term of
157 1.1 skrll copyright on the Program, and are irrevocable provided the stated
158 1.1 skrll conditions are met. This License explicitly affirms your unlimited
159 1.1 skrll permission to run the unmodified Program. The output from running a
160 1.1 skrll covered work is covered by this License only if the output, given its
161 1.1 skrll content, constitutes a covered work. This License acknowledges your
162 1.1 skrll rights of fair use or other equivalent, as provided by copyright law.
163 1.1 skrll
164 1.1 skrll You may make, run and propagate covered works that you do not
165 1.1 skrll convey, without conditions so long as your license otherwise remains
166 1.1 skrll in force. You may convey covered works to others for the sole purpose
167 1.1 skrll of having them make modifications exclusively for you, or provide you
168 1.1 skrll with facilities for running those works, provided that you comply with
169 1.1 skrll the terms of this License in conveying all material for which you do
170 1.1 skrll not control copyright. Those thus making or running the covered works
171 1.1 skrll for you must do so exclusively on your behalf, under your direction
172 1.1 skrll and control, on terms that prohibit them from making any copies of
173 1.1 skrll your copyrighted material outside their relationship with you.
174 1.1 skrll
175 1.1 skrll Conveying under any other circumstances is permitted solely under
176 1.1 skrll the conditions stated below. Sublicensing is not allowed; section 10
177 1.1 skrll makes it unnecessary.
178 1.1 skrll
179 1.1 skrll 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
180 1.1 skrll
181 1.1 skrll No covered work shall be deemed part of an effective technological
182 1.1 skrll measure under any applicable law fulfilling obligations under article
183 1.1 skrll 11 of the WIPO copyright treaty adopted on 20 December 1996, or
184 1.1 skrll similar laws prohibiting or restricting circumvention of such
185 1.1 skrll measures.
186 1.1 skrll
187 1.1 skrll When you convey a covered work, you waive any legal power to forbid
188 1.1 skrll circumvention of technological measures to the extent such circumvention
189 1.1 skrll is effected by exercising rights under this License with respect to
190 1.1 skrll the covered work, and you disclaim any intention to limit operation or
191 1.1 skrll modification of the work as a means of enforcing, against the work's
192 1.1 skrll users, your or third parties' legal rights to forbid circumvention of
193 1.1 skrll technological measures.
194 1.1 skrll
195 1.1 skrll 4. Conveying Verbatim Copies.
196 1.1 skrll
197 1.1 skrll You may convey verbatim copies of the Program's source code as you
198 1.1 skrll receive it, in any medium, provided that you conspicuously and
199 1.1 skrll appropriately publish on each copy an appropriate copyright notice;
200 1.1 skrll keep intact all notices stating that this License and any
201 1.1 skrll non-permissive terms added in accord with section 7 apply to the code;
202 1.1 skrll keep intact all notices of the absence of any warranty; and give all
203 1.1 skrll recipients a copy of this License along with the Program.
204 1.1 skrll
205 1.1 skrll You may charge any price or no price for each copy that you convey,
206 1.1 skrll and you may offer support or warranty protection for a fee.
207 1.1 skrll
208 1.1 skrll 5. Conveying Modified Source Versions.
209 1.1 skrll
210 1.1 skrll You may convey a work based on the Program, or the modifications to
211 1.1 skrll produce it from the Program, in the form of source code under the
212 1.1 skrll terms of section 4, provided that you also meet all of these conditions:
213 1.1 skrll
214 1.1 skrll a) The work must carry prominent notices stating that you modified
215 1.1 skrll it, and giving a relevant date.
216 1.1 skrll
217 1.1 skrll b) The work must carry prominent notices stating that it is
218 1.1 skrll released under this License and any conditions added under section
219 1.1 skrll 7. This requirement modifies the requirement in section 4 to
220 1.1 skrll "keep intact all notices".
221 1.1 skrll
222 1.1 skrll c) You must license the entire work, as a whole, under this
223 1.1 skrll License to anyone who comes into possession of a copy. This
224 1.1 skrll License will therefore apply, along with any applicable section 7
225 1.1 skrll additional terms, to the whole of the work, and all its parts,
226 1.1 skrll regardless of how they are packaged. This License gives no
227 1.1 skrll permission to license the work in any other way, but it does not
228 1.1 skrll invalidate such permission if you have separately received it.
229 1.1 skrll
230 1.1 skrll d) If the work has interactive user interfaces, each must display
231 1.1 skrll Appropriate Legal Notices; however, if the Program has interactive
232 1.1 skrll interfaces that do not display Appropriate Legal Notices, your
233 1.1 skrll work need not make them do so.
234 1.1 skrll
235 1.1 skrll A compilation of a covered work with other separate and independent
236 1.1 skrll works, which are not by their nature extensions of the covered work,
237 1.1 skrll and which are not combined with it such as to form a larger program,
238 1.1 skrll in or on a volume of a storage or distribution medium, is called an
239 1.1 skrll "aggregate" if the compilation and its resulting copyright are not
240 1.1 skrll used to limit the access or legal rights of the compilation's users
241 1.1 skrll beyond what the individual works permit. Inclusion of a covered work
242 1.1 skrll in an aggregate does not cause this License to apply to the other
243 1.1 skrll parts of the aggregate.
244 1.1 skrll
245 1.1 skrll 6. Conveying Non-Source Forms.
246 1.1 skrll
247 1.1 skrll You may convey a covered work in object code form under the terms
248 1.1 skrll of sections 4 and 5, provided that you also convey the
249 1.1 skrll machine-readable Corresponding Source under the terms of this License,
250 1.1 skrll in one of these ways:
251 1.1 skrll
252 1.1 skrll a) Convey the object code in, or embodied in, a physical product
253 1.1 skrll (including a physical distribution medium), accompanied by the
254 1.1 skrll Corresponding Source fixed on a durable physical medium
255 1.1 skrll customarily used for software interchange.
256 1.1 skrll
257 1.1 skrll b) Convey the object code in, or embodied in, a physical product
258 1.1 skrll (including a physical distribution medium), accompanied by a
259 1.1 skrll written offer, valid for at least three years and valid for as
260 1.1 skrll long as you offer spare parts or customer support for that product
261 1.1 skrll model, to give anyone who possesses the object code either (1) a
262 1.1 skrll copy of the Corresponding Source for all the software in the
263 1.1 skrll product that is covered by this License, on a durable physical
264 1.1 skrll medium customarily used for software interchange, for a price no
265 1.1 skrll more than your reasonable cost of physically performing this
266 1.1 skrll conveying of source, or (2) access to copy the
267 1.1 skrll Corresponding Source from a network server at no charge.
268 1.1 skrll
269 1.1 skrll c) Convey individual copies of the object code with a copy of the
270 1.1 skrll written offer to provide the Corresponding Source. This
271 1.1 skrll alternative is allowed only occasionally and noncommercially, and
272 1.1 skrll only if you received the object code with such an offer, in accord
273 1.1 skrll with subsection 6b.
274 1.1 skrll
275 1.1 skrll d) Convey the object code by offering access from a designated
276 1.1 skrll place (gratis or for a charge), and offer equivalent access to the
277 1.1 skrll Corresponding Source in the same way through the same place at no
278 1.1 skrll further charge. You need not require recipients to copy the
279 1.1 skrll Corresponding Source along with the object code. If the place to
280 1.1 skrll copy the object code is a network server, the Corresponding Source
281 1.1 skrll may be on a different server (operated by you or a third party)
282 1.1 skrll that supports equivalent copying facilities, provided you maintain
283 1.1 skrll clear directions next to the object code saying where to find the
284 1.1 skrll Corresponding Source. Regardless of what server hosts the
285 1.1 skrll Corresponding Source, you remain obligated to ensure that it is
286 1.1 skrll available for as long as needed to satisfy these requirements.
287 1.1 skrll
288 1.1 skrll e) Convey the object code using peer-to-peer transmission, provided
289 1.1 skrll you inform other peers where the object code and Corresponding
290 1.1 skrll Source of the work are being offered to the general public at no
291 1.1 skrll charge under subsection 6d.
292 1.1 skrll
293 1.1 skrll A separable portion of the object code, whose source code is excluded
294 1.1 skrll from the Corresponding Source as a System Library, need not be
295 1.1 skrll included in conveying the object code work.
296 1.1 skrll
297 1.1 skrll A "User Product" is either (1) a "consumer product", which means any
298 1.1 skrll tangible personal property which is normally used for personal, family,
299 1.1 skrll or household purposes, or (2) anything designed or sold for incorporation
300 1.1 skrll into a dwelling. In determining whether a product is a consumer product,
301 1.1 skrll doubtful cases shall be resolved in favor of coverage. For a particular
302 1.1 skrll product received by a particular user, "normally used" refers to a
303 1.1 skrll typical or common use of that class of product, regardless of the status
304 1.1 skrll of the particular user or of the way in which the particular user
305 1.1 skrll actually uses, or expects or is expected to use, the product. A product
306 1.1 skrll is a consumer product regardless of whether the product has substantial
307 1.1 skrll commercial, industrial or non-consumer uses, unless such uses represent
308 1.1 skrll the only significant mode of use of the product.
309 1.1 skrll
310 1.1 skrll "Installation Information" for a User Product means any methods,
311 1.1 skrll procedures, authorization keys, or other information required to install
312 1.1 skrll and execute modified versions of a covered work in that User Product from
313 1.1 skrll a modified version of its Corresponding Source. The information must
314 1.1 skrll suffice to ensure that the continued functioning of the modified object
315 1.1 skrll code is in no case prevented or interfered with solely because
316 1.1 skrll modification has been made.
317 1.1 skrll
318 1.1 skrll If you convey an object code work under this section in, or with, or
319 1.1 skrll specifically for use in, a User Product, and the conveying occurs as
320 1.1 skrll part of a transaction in which the right of possession and use of the
321 1.1 skrll User Product is transferred to the recipient in perpetuity or for a
322 1.1 skrll fixed term (regardless of how the transaction is characterized), the
323 1.1 skrll Corresponding Source conveyed under this section must be accompanied
324 1.1 skrll by the Installation Information. But this requirement does not apply
325 1.1 skrll if neither you nor any third party retains the ability to install
326 1.1 skrll modified object code on the User Product (for example, the work has
327 1.1 skrll been installed in ROM).
328 1.1 skrll
329 1.1 skrll The requirement to provide Installation Information does not include a
330 1.1 skrll requirement to continue to provide support service, warranty, or updates
331 1.1 skrll for a work that has been modified or installed by the recipient, or for
332 1.1 skrll the User Product in which it has been modified or installed. Access to a
333 1.1 skrll network may be denied when the modification itself materially and
334 1.1 skrll adversely affects the operation of the network or violates the rules and
335 1.1 skrll protocols for communication across the network.
336 1.1 skrll
337 1.1 skrll Corresponding Source conveyed, and Installation Information provided,
338 1.1 skrll in accord with this section must be in a format that is publicly
339 1.1 skrll documented (and with an implementation available to the public in
340 1.1 skrll source code form), and must require no special password or key for
341 1.1 skrll unpacking, reading or copying.
342 1.1 skrll
343 1.1 skrll 7. Additional Terms.
344 1.1 skrll
345 1.1 skrll "Additional permissions" are terms that supplement the terms of this
346 1.1 skrll License by making exceptions from one or more of its conditions.
347 1.1 skrll Additional permissions that are applicable to the entire Program shall
348 1.1 skrll be treated as though they were included in this License, to the extent
349 1.1 skrll that they are valid under applicable law. If additional permissions
350 1.1 skrll apply only to part of the Program, that part may be used separately
351 1.1 skrll under those permissions, but the entire Program remains governed by
352 1.1 skrll this License without regard to the additional permissions.
353 1.1 skrll
354 1.1 skrll When you convey a copy of a covered work, you may at your option
355 1.1 skrll remove any additional permissions from that copy, or from any part of
356 1.1 skrll it. (Additional permissions may be written to require their own
357 1.1 skrll removal in certain cases when you modify the work.) You may place
358 1.1 skrll additional permissions on material, added by you to a covered work,
359 1.1 skrll for which you have or can give appropriate copyright permission.
360 1.1 skrll
361 1.1 skrll Notwithstanding any other provision of this License, for material you
362 1.1 skrll add to a covered work, you may (if authorized by the copyright holders of
363 1.1 skrll that material) supplement the terms of this License with terms:
364 1.1 skrll
365 1.1 skrll a) Disclaiming warranty or limiting liability differently from the
366 1.1 skrll terms of sections 15 and 16 of this License; or
367 1.1 skrll
368 1.1 skrll b) Requiring preservation of specified reasonable legal notices or
369 1.1 skrll author attributions in that material or in the Appropriate Legal
370 1.1 skrll Notices displayed by works containing it; or
371 1.1 skrll
372 1.1 skrll c) Prohibiting misrepresentation of the origin of that material, or
373 1.1 skrll requiring that modified versions of such material be marked in
374 1.1 skrll reasonable ways as different from the original version; or
375 1.1 skrll
376 1.1 skrll d) Limiting the use for publicity purposes of names of licensors or
377 1.1 skrll authors of the material; or
378 1.1 skrll
379 1.1 skrll e) Declining to grant rights under trademark law for use of some
380 1.1 skrll trade names, trademarks, or service marks; or
381 1.1 skrll
382 1.1 skrll f) Requiring indemnification of licensors and authors of that
383 1.1 skrll material by anyone who conveys the material (or modified versions of
384 1.1 skrll it) with contractual assumptions of liability to the recipient, for
385 1.1 skrll any liability that these contractual assumptions directly impose on
386 1.1 skrll those licensors and authors.
387 1.1 skrll
388 1.1 skrll All other non-permissive additional terms are considered "further
389 1.1 skrll restrictions" within the meaning of section 10. If the Program as you
390 1.1 skrll received it, or any part of it, contains a notice stating that it is
391 1.1 skrll governed by this License along with a term that is a further
392 1.1 skrll restriction, you may remove that term. If a license document contains
393 1.1 skrll a further restriction but permits relicensing or conveying under this
394 1.1 skrll License, you may add to a covered work material governed by the terms
395 1.1 skrll of that license document, provided that the further restriction does
396 1.1 skrll not survive such relicensing or conveying.
397 1.1 skrll
398 1.1 skrll If you add terms to a covered work in accord with this section, you
399 1.1 skrll must place, in the relevant source files, a statement of the
400 1.1 skrll additional terms that apply to those files, or a notice indicating
401 1.1 skrll where to find the applicable terms.
402 1.1 skrll
403 1.1 skrll Additional terms, permissive or non-permissive, may be stated in the
404 1.1 skrll form of a separately written license, or stated as exceptions;
405 1.1 skrll the above requirements apply either way.
406 1.1 skrll
407 1.1 skrll 8. Termination.
408 1.1 skrll
409 1.1 skrll You may not propagate or modify a covered work except as expressly
410 1.1 skrll provided under this License. Any attempt otherwise to propagate or
411 1.1 skrll modify it is void, and will automatically terminate your rights under
412 1.1 skrll this License (including any patent licenses granted under the third
413 1.1 skrll paragraph of section 11).
414 1.1 skrll
415 1.1 skrll However, if you cease all violation of this License, then your
416 1.1 skrll license from a particular copyright holder is reinstated (a)
417 1.1 skrll provisionally, unless and until the copyright holder explicitly and
418 1.1 skrll finally terminates your license, and (b) permanently, if the copyright
419 1.1 skrll holder fails to notify you of the violation by some reasonable means
420 1.1 skrll prior to 60 days after the cessation.
421 1.1 skrll
422 1.1 skrll Moreover, your license from a particular copyright holder is
423 1.1 skrll reinstated permanently if the copyright holder notifies you of the
424 1.1 skrll violation by some reasonable means, this is the first time you have
425 1.1 skrll received notice of violation of this License (for any work) from that
426 1.1 skrll copyright holder, and you cure the violation prior to 30 days after
427 1.1 skrll your receipt of the notice.
428 1.1 skrll
429 1.1 skrll Termination of your rights under this section does not terminate the
430 1.1 skrll licenses of parties who have received copies or rights from you under
431 1.1 skrll this License. If your rights have been terminated and not permanently
432 1.1 skrll reinstated, you do not qualify to receive new licenses for the same
433 1.1 skrll material under section 10.
434 1.1 skrll
435 1.1 skrll 9. Acceptance Not Required for Having Copies.
436 1.1 skrll
437 1.1 skrll You are not required to accept this License in order to receive or
438 1.1 skrll run a copy of the Program. Ancillary propagation of a covered work
439 1.1 skrll occurring solely as a consequence of using peer-to-peer transmission
440 1.1 skrll to receive a copy likewise does not require acceptance. However,
441 1.1 skrll nothing other than this License grants you permission to propagate or
442 1.1 skrll modify any covered work. These actions infringe copyright if you do
443 1.1 skrll not accept this License. Therefore, by modifying or propagating a
444 1.1 skrll covered work, you indicate your acceptance of this License to do so.
445 1.1 skrll
446 1.1 skrll 10. Automatic Licensing of Downstream Recipients.
447 1.1 skrll
448 1.1 skrll Each time you convey a covered work, the recipient automatically
449 1.1 skrll receives a license from the original licensors, to run, modify and
450 1.1 skrll propagate that work, subject to this License. You are not responsible
451 1.1 skrll for enforcing compliance by third parties with this License.
452 1.1 skrll
453 1.1 skrll An "entity transaction" is a transaction transferring control of an
454 1.1 skrll organization, or substantially all assets of one, or subdividing an
455 1.1 skrll organization, or merging organizations. If propagation of a covered
456 1.1 skrll work results from an entity transaction, each party to that
457 1.1 skrll transaction who receives a copy of the work also receives whatever
458 1.1 skrll licenses to the work the party's predecessor in interest had or could
459 1.1 skrll give under the previous paragraph, plus a right to possession of the
460 1.1 skrll Corresponding Source of the work from the predecessor in interest, if
461 1.1 skrll the predecessor has it or can get it with reasonable efforts.
462 1.1 skrll
463 1.1 skrll You may not impose any further restrictions on the exercise of the
464 1.1 skrll rights granted or affirmed under this License. For example, you may
465 1.1 skrll not impose a license fee, royalty, or other charge for exercise of
466 1.1 skrll rights granted under this License, and you may not initiate litigation
467 1.1 skrll (including a cross-claim or counterclaim in a lawsuit) alleging that
468 1.1 skrll any patent claim is infringed by making, using, selling, offering for
469 1.1 skrll sale, or importing the Program or any portion of it.
470 1.1 skrll
471 1.1 skrll 11. Patents.
472 1.1 skrll
473 1.1 skrll A "contributor" is a copyright holder who authorizes use under this
474 1.1 skrll License of the Program or a work on which the Program is based. The
475 1.1 skrll work thus licensed is called the contributor's "contributor version".
476 1.1 skrll
477 1.1 skrll A contributor's "essential patent claims" are all patent claims
478 1.1 skrll owned or controlled by the contributor, whether already acquired or
479 1.1 skrll hereafter acquired, that would be infringed by some manner, permitted
480 1.1 skrll by this License, of making, using, or selling its contributor version,
481 1.1 skrll but do not include claims that would be infringed only as a
482 1.1 skrll consequence of further modification of the contributor version. For
483 1.1 skrll purposes of this definition, "control" includes the right to grant
484 1.1 skrll patent sublicenses in a manner consistent with the requirements of
485 1.1 skrll this License.
486 1.1 skrll
487 1.1 skrll Each contributor grants you a non-exclusive, worldwide, royalty-free
488 1.1 skrll patent license under the contributor's essential patent claims, to
489 1.1 skrll make, use, sell, offer for sale, import and otherwise run, modify and
490 1.1 skrll propagate the contents of its contributor version.
491 1.1 skrll
492 1.1 skrll In the following three paragraphs, a "patent license" is any express
493 1.1 skrll agreement or commitment, however denominated, not to enforce a patent
494 1.1 skrll (such as an express permission to practice a patent or covenant not to
495 1.1 skrll sue for patent infringement). To "grant" such a patent license to a
496 1.1 skrll party means to make such an agreement or commitment not to enforce a
497 1.1 skrll patent against the party.
498 1.1 skrll
499 1.1 skrll If you convey a covered work, knowingly relying on a patent license,
500 1.1 skrll and the Corresponding Source of the work is not available for anyone
501 1.1 skrll to copy, free of charge and under the terms of this License, through a
502 1.1 skrll publicly available network server or other readily accessible means,
503 1.1 skrll then you must either (1) cause the Corresponding Source to be so
504 1.1 skrll available, or (2) arrange to deprive yourself of the benefit of the
505 1.1 skrll patent license for this particular work, or (3) arrange, in a manner
506 1.1 skrll consistent with the requirements of this License, to extend the patent
507 1.1 skrll license to downstream recipients. "Knowingly relying" means you have
508 1.1 skrll actual knowledge that, but for the patent license, your conveying the
509 1.1 skrll covered work in a country, or your recipient's use of the covered work
510 1.1 skrll in a country, would infringe one or more identifiable patents in that
511 1.1 skrll country that you have reason to believe are valid.
512 1.1 skrll
513 1.1 skrll If, pursuant to or in connection with a single transaction or
514 1.1 skrll arrangement, you convey, or propagate by procuring conveyance of, a
515 1.1 skrll covered work, and grant a patent license to some of the parties
516 1.1 skrll receiving the covered work authorizing them to use, propagate, modify
517 1.1 skrll or convey a specific copy of the covered work, then the patent license
518 1.1 skrll you grant is automatically extended to all recipients of the covered
519 1.1 skrll work and works based on it.
520 1.1 skrll
521 1.1 skrll A patent license is "discriminatory" if it does not include within
522 1.1 skrll the scope of its coverage, prohibits the exercise of, or is
523 1.1 skrll conditioned on the non-exercise of one or more of the rights that are
524 1.1 skrll specifically granted under this License. You may not convey a covered
525 1.1 skrll work if you are a party to an arrangement with a third party that is
526 1.1 skrll in the business of distributing software, under which you make payment
527 1.1 skrll to the third party based on the extent of your activity of conveying
528 1.1 skrll the work, and under which the third party grants, to any of the
529 1.1 skrll parties who would receive the covered work from you, a discriminatory
530 1.1 skrll patent license (a) in connection with copies of the covered work
531 1.1 skrll conveyed by you (or copies made from those copies), or (b) primarily
532 1.1 skrll for and in connection with specific products or compilations that
533 1.1 skrll contain the covered work, unless you entered into that arrangement,
534 1.1 skrll or that patent license was granted, prior to 28 March 2007.
535 1.1 skrll
536 1.1 skrll Nothing in this License shall be construed as excluding or limiting
537 1.1 skrll any implied license or other defenses to infringement that may
538 1.1 skrll otherwise be available to you under applicable patent law.
539 1.1 skrll
540 1.1 skrll 12. No Surrender of Others' Freedom.
541 1.1 skrll
542 1.1 skrll If conditions are imposed on you (whether by court order, agreement or
543 1.1 skrll otherwise) that contradict the conditions of this License, they do not
544 1.1 skrll excuse you from the conditions of this License. If you cannot convey a
545 1.1 skrll covered work so as to satisfy simultaneously your obligations under this
546 1.1 skrll License and any other pertinent obligations, then as a consequence you may
547 1.1 skrll not convey it at all. For example, if you agree to terms that obligate you
548 1.1 skrll to collect a royalty for further conveying from those to whom you convey
549 1.1 skrll the Program, the only way you could satisfy both those terms and this
550 1.1 skrll License would be to refrain entirely from conveying the Program.
551 1.1 skrll
552 1.1 skrll 13. Use with the GNU Affero General Public License.
553 1.1 skrll
554 1.1 skrll Notwithstanding any other provision of this License, you have
555 1.1 skrll permission to link or combine any covered work with a work licensed
556 1.1 skrll under version 3 of the GNU Affero General Public License into a single
557 1.1 skrll combined work, and to convey the resulting work. The terms of this
558 1.1 skrll License will continue to apply to the part which is the covered work,
559 1.1 skrll but the special requirements of the GNU Affero General Public License,
560 1.1 skrll section 13, concerning interaction through a network will apply to the
561 1.1 skrll combination as such.
562 1.1 skrll
563 1.1 skrll 14. Revised Versions of this License.
564 1.1 skrll
565 1.1 skrll The Free Software Foundation may publish revised and/or new versions of
566 1.1 skrll the GNU General Public License from time to time. Such new versions will
567 1.1 skrll be similar in spirit to the present version, but may differ in detail to
568 1.1 skrll address new problems or concerns.
569 1.1 skrll
570 1.1 skrll Each version is given a distinguishing version number. If the
571 1.1 skrll Program specifies that a certain numbered version of the GNU General
572 1.1 skrll Public License "or any later version" applies to it, you have the
573 1.1 skrll option of following the terms and conditions either of that numbered
574 1.1 skrll version or of any later version published by the Free Software
575 1.1 skrll Foundation. If the Program does not specify a version number of the
576 1.1 skrll GNU General Public License, you may choose any version ever published
577 1.1 skrll by the Free Software Foundation.
578 1.1 skrll
579 1.1 skrll If the Program specifies that a proxy can decide which future
580 1.1 skrll versions of the GNU General Public License can be used, that proxy's
581 1.1 skrll public statement of acceptance of a version permanently authorizes you
582 1.1 skrll to choose that version for the Program.
583 1.1 skrll
584 1.1 skrll Later license versions may give you additional or different
585 1.1 skrll permissions. However, no additional obligations are imposed on any
586 1.1 skrll author or copyright holder as a result of your choosing to follow a
587 1.1 skrll later version.
588 1.1 skrll
589 1.1 skrll 15. Disclaimer of Warranty.
590 1.1 skrll
591 1.1 skrll THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
592 1.1 skrll APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
593 1.1 skrll HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
594 1.1 skrll OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
595 1.1 skrll THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
596 1.1 skrll PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
597 1.1 skrll IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
598 1.1 skrll ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
599 1.1 skrll
600 1.1 skrll 16. Limitation of Liability.
601 1.1 skrll
602 1.1 skrll IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
603 1.1 skrll WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
604 1.1 skrll THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
605 1.1 skrll GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
606 1.1 skrll USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
607 1.1 skrll DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
608 1.1 skrll PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
609 1.1 skrll EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
610 1.1 skrll SUCH DAMAGES.
611 1.1 skrll
612 1.1 skrll 17. Interpretation of Sections 15 and 16.
613 1.1 skrll
614 1.1 skrll If the disclaimer of warranty and limitation of liability provided
615 1.1 skrll above cannot be given local legal effect according to their terms,
616 1.1 skrll reviewing courts shall apply local law that most closely approximates
617 1.1 skrll an absolute waiver of all civil liability in connection with the
618 1.1 skrll Program, unless a warranty or assumption of liability accompanies a
619 1.1 skrll copy of the Program in return for a fee.
620 1.1 skrll
621 1.1 skrll END OF TERMS AND CONDITIONS
622 1.1 skrll
623 1.1 skrll How to Apply These Terms to Your New Programs
624 1.1 skrll
625 1.1 skrll If you develop a new program, and you want it to be of the greatest
626 1.1 skrll possible use to the public, the best way to achieve this is to make it
627 1.1 skrll free software which everyone can redistribute and change under these terms.
628 1.1 skrll
629 1.1 skrll To do so, attach the following notices to the program. It is safest
630 1.1 skrll to attach them to the start of each source file to most effectively
631 1.1 skrll state the exclusion of warranty; and each file should have at least
632 1.1 skrll the "copyright" line and a pointer to where the full notice is found.
633 1.1 skrll
634 1.1 skrll <one line to give the program's name and a brief idea of what it does.>
635 1.1 skrll Copyright (C) <year> <name of author>
636 1.1 skrll
637 1.1 skrll This program is free software: you can redistribute it and/or modify
638 1.1 skrll it under the terms of the GNU General Public License as published by
639 1.1 skrll the Free Software Foundation, either version 3 of the License, or
640 1.1 skrll (at your option) any later version.
641 1.1 skrll
642 1.1 skrll This program is distributed in the hope that it will be useful,
643 1.1 skrll but WITHOUT ANY WARRANTY; without even the implied warranty of
644 1.1 skrll MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
645 1.1 skrll GNU General Public License for more details.
646 1.1 skrll
647 1.1 skrll You should have received a copy of the GNU General Public License
648 1.1 skrll along with this program. If not, see <http://www.gnu.org/licenses/>.
649 1.1 skrll
650 1.1 skrll Also add information on how to contact you by electronic and paper mail.
651 1.1 skrll
652 1.1 skrll If the program does terminal interaction, make it output a short
653 1.1 skrll notice like this when it starts in an interactive mode:
654 1.1 skrll
655 1.1 skrll <program> Copyright (C) <year> <name of author>

658 1.1 skrll under certain conditions; type `show c' for details.
659 1.1 skrll
660 1.1 skrll The hypothetical commands `show w' and `show c' should show the appropriate
661 1.1 skrll parts of the General Public License. Of course, your program's commands
662 1.1 skrll might be different; for a GUI interface, you would use an "about box".
663 1.1 skrll
664 1.1 skrll You should also get your employer (if you work as a programmer) or school,
665 1.1 skrll if any, to sign a "copyright disclaimer" for the program, if necessary.

668 1.1 skrll
669 1.1 skrll The GNU General Public License does not permit incorporating your program
670 1.1 skrll into proprietary programs. If your program is a subroutine library, you
671 1.1 skrll may consider it more useful to permit linking proprietary applications with
672 1.1 skrll the library. If this is what you want to do, use the GNU Lesser General
