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

640 1.1 christos (at your option) any later version.

642 1.1 christos This program is distributed in the hope that it will be useful,
643 1.1 christos but WITHOUT ANY WARRANTY; without even the implied warranty of
644 1.1 christos MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
645 1.1 christos GNU General Public License for more details.
646 1.1 christos
647 1.1 christos You should have received a copy of the GNU General Public License
648 1.1 christos along with this program. If not, see <http://www.gnu.org/licenses/>.
649 1.1 christos
650 1.1 christos Also add information on how to contact you by electronic and paper mail.
651 1.1 christos
652 1.1 christos If the program does terminal interaction, make it output a short
653 1.1 christos notice like this when it starts in an interactive mode:
654 1.1 christos
655 1.1 christos <program> Copyright (C) <year> <name of author>

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

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