48Preamble
Spyridon Mastorakis460f57c2014-12-17 00:44:14 -080049========
Alexander Afanasyevf34fe562013-08-09 17:16:12 -070050
Spyridon Mastorakis460f57c2014-12-17 00:44:14 -080051The GNU General Public License is a free, copyleft license for software and other kinds of works.
Alexander Afanasyevf34fe562013-08-09 17:16:12 -070052
Spyridon Mastorakis460f57c2014-12-17 00:44:14 -080053The licenses for most software and other practical works are designed to take away your freedom to
54share and change the works. By contrast, the GNU General Public License is intended to guarantee
55your freedom to share and change all versions of a program--to make sure it remains free software
56for all its users. We, the Free Software Foundation, use the GNU General Public License for most of
57our software; it applies also to any other work released this way by its authors. You can apply it
58to your programs, too.
Alexander Afanasyevf34fe562013-08-09 17:16:12 -070059
Spyridon Mastorakis460f57c2014-12-17 00:44:14 -080060When we speak of free software, we are referring to freedom, not price. Our General Public Licenses
61are designed to make sure that you have the freedom to distribute copies of free software (and
62charge for them if you wish), that you receive source code or can get it if you want it, that you
63can change the software or use pieces of it in new free programs, and that you know you can do these
64things.
Alexander Afanasyevf34fe562013-08-09 17:16:12 -070065
Spyridon Mastorakis460f57c2014-12-17 00:44:14 -080066To protect your rights, we need to prevent others from denying you these rights or asking you to
67surrender the rights. Therefore, you have certain responsibilities if you distribute copies of the
68software, or if you modify it: responsibilities to respect the freedom of others.
Alexander Afanasyevf34fe562013-08-09 17:16:12 -070069
Spyridon Mastorakis460f57c2014-12-17 00:44:14 -080070For example, if you distribute copies of such a program, whether gratis or for a fee, you must pass
71on to the recipients the same freedoms that you received. You must make sure that they, too, receive
72or can get the source code. And you must show them these terms so they know their rights.
Alexander Afanasyevf34fe562013-08-09 17:16:12 -070073
Spyridon Mastorakis460f57c2014-12-17 00:44:14 -080074Developers that use the GNU GPL protect your rights with two steps: (1) assert copyright on the
75software, and (2) offer you this License giving you legal permission to copy, distribute and/or
76modify it.
Alexander Afanasyevf34fe562013-08-09 17:16:12 -070077
Spyridon Mastorakis460f57c2014-12-17 00:44:14 -080078For the developers' and authors' protection, the GPL clearly explains that there is no warranty for
79this free software. For both users' and authors' sake, the GPL requires that modified versions be
80marked as changed, so that their problems will not be attributed erroneously to authors of previous
81versions.
Alexander Afanasyevf34fe562013-08-09 17:16:12 -070082
Spyridon Mastorakis460f57c2014-12-17 00:44:14 -080083Some devices are designed to deny users access to install or run modified versions of the software
84inside them, although the manufacturer can do so. This is fundamentally incompatible with the aim of
85protecting users' freedom to change the software. The systematic pattern of such abuse occurs in the
86area of products for individuals to use, which is precisely where it is most unacceptable.
87Therefore, we have designed this version of the GPL to prohibit the practice for those products. If
88such problems arise substantially in other domains, we stand ready to extend this provision to those
89domains in future versions of the GPL, as needed to protect the freedom of users.
Alexander Afanasyevf34fe562013-08-09 17:16:12 -070090
Spyridon Mastorakis460f57c2014-12-17 00:44:14 -080091Finally, every program is threatened constantly by software patents. States should not allow patents
92to restrict development and use of software on general-purpose computers, but in those that do, we
93wish to avoid the special danger that patents applied to a free program could make it effectively
94proprietary. To prevent this, the GPL assures that patents cannot be used to render the program
95non-free.
Alexander Afanasyevf34fe562013-08-09 17:16:12 -070096
Spyridon Mastorakis460f57c2014-12-17 00:44:14 -080097The precise terms and conditions for copying, distribution and modification follow.

Spyridon Mastorakis460f57c2014-12-17 00:44:14 -080099TERMS AND CONDITIONS
100====================
Alexander Afanasyevf34fe562013-08-09 17:16:12 -0700101
Spyridon Mastorakis460f57c2014-12-17 00:44:14 -08001020. Definitions.
103---------------
Alexander Afanasyevf34fe562013-08-09 17:16:12 -0700104
Spyridon Mastorakis460f57c2014-12-17 00:44:14 -0800105*"This License"* refers to version 3 of the GNU General Public License.
Alexander Afanasyevf34fe562013-08-09 17:16:12 -0700106
Spyridon Mastorakis460f57c2014-12-17 00:44:14 -0800107*"Copyright"* also means copyright-like laws that apply to other kinds of works, such as
108semiconductor masks.
Alexander Afanasyevf34fe562013-08-09 17:16:12 -0700109
Spyridon Mastorakis460f57c2014-12-17 00:44:14 -0800110*"The Program"* refers to any copyrightable work licensed under this License. Each licensee is
111addressed as *"you"*. *"Licensees"* and "recipients" may be individuals or organizations.
Alexander Afanasyevf34fe562013-08-09 17:16:12 -0700112
Spyridon Mastorakis460f57c2014-12-17 00:44:14 -0800113To *"modify"* a work means to copy from or adapt all or part of the work in a fashion requiring
114copyright permission, other than the making of an exact copy. The resulting work is called a
115*"modified version"* of the earlier work or a work *"based on"* the earlier work.
Alexander Afanasyevf34fe562013-08-09 17:16:12 -0700116
Spyridon Mastorakis460f57c2014-12-17 00:44:14 -0800117A *"covered work"* means either the unmodified Program or a work based on the Program.
Alexander Afanasyevf34fe562013-08-09 17:16:12 -0700118
Spyridon Mastorakis460f57c2014-12-17 00:44:14 -0800119To *"propagate"* a work means to do anything with it that, without permission, would make you
120directly or secondarily liable for infringement under applicable copyright law, except executing it
121on a computer or modifying a private copy. Propagation includes copying, distribution (with or
122without modification), making available to the public, and in some countries other activities as
123well.
Alexander Afanasyevf34fe562013-08-09 17:16:12 -0700124
Spyridon Mastorakis460f57c2014-12-17 00:44:14 -0800125To *"convey"* a work means any kind of propagation that enables other parties to make or receive
126copies. Mere interaction with a user through a computer network, with no transfer of a copy, is not
127conveying.
Alexander Afanasyevf34fe562013-08-09 17:16:12 -0700128
Spyridon Mastorakis460f57c2014-12-17 00:44:14 -0800129An interactive user interface displays "Appropriate Legal Notices" to the extent that it includes a
130convenient and prominently visible feature that (1) displays an appropriate copyright notice, and
131(2) tells the user that there is no warranty for the work (except to the extent that warranties are
132provided), that licensees may convey the work under this License, and how to view a copy of this
133License. If the interface presents a list of user commands or options, such as a menu, a prominent
134item in the list meets this criterion.
Alexander Afanasyevf34fe562013-08-09 17:16:12 -0700135
Spyridon Mastorakis460f57c2014-12-17 00:44:14 -08001361. Source Code.
137---------------
Alexander Afanasyevf34fe562013-08-09 17:16:12 -0700138
Spyridon Mastorakis460f57c2014-12-17 00:44:14 -0800139The *"source code"* for a work means the preferred form of the work for making modifications to it.
140*"Object code"* means any non-source form of a work.
Alexander Afanasyevf34fe562013-08-09 17:16:12 -0700141
Spyridon Mastorakis460f57c2014-12-17 00:44:14 -0800142A *"Standard Interface"* means an interface that either is an official standard defined by a
143recognized standards body, or, in the case of interfaces specified for a particular programming
144language, one that is widely used among developers working in that language.
Alexander Afanasyevf34fe562013-08-09 17:16:12 -0700145
Spyridon Mastorakis460f57c2014-12-17 00:44:14 -0800146The *"System Libraries"* of an executable work include anything, other than the work as a whole,
147that (a) is included in the normal form of packaging a Major Component, but which is not part of
148that Major Component, and (b) serves only to enable use of the work with that Major Component, or to
149implement a Standard Interface for which an implementation is available to the public in source code
150form. A "Major Component", in this context, means a major essential component (kernel, window
151system, and so on) of the specific operating system (if any) on which the executable work runs, or a
152compiler used to produce the work, or an object code interpreter used to run it.
Alexander Afanasyevf34fe562013-08-09 17:16:12 -0700153
Spyridon Mastorakis460f57c2014-12-17 00:44:14 -0800154The *"Corresponding Source"* for a work in object code form means all the source code needed to
155generate, install, and (for an executable work) run the object code and to modify the work,
156including scripts to control those activities. However, it does not include the work's System
157Libraries, or general-purpose tools or generally available free programs which are used unmodified
158in performing those activities but which are not part of the work. For example, Corresponding Source
159includes interface definition files associated with source files for the work, and the source code
160for shared libraries and dynamically linked subprograms that the work is specifically designed to
161require, such as by intimate data communication or control flow between those subprograms and other
162parts of the work.
Alexander Afanasyevf34fe562013-08-09 17:16:12 -0700163
Spyridon Mastorakis460f57c2014-12-17 00:44:14 -0800164The Corresponding Source need not include anything that users can regenerate automatically from
165other parts of the Corresponding Source.
Alexander Afanasyevf34fe562013-08-09 17:16:12 -0700166
Spyridon Mastorakis460f57c2014-12-17 00:44:14 -0800167The Corresponding Source for a work in source code form is that same work.
Alexander Afanasyevf34fe562013-08-09 17:16:12 -0700168
Spyridon Mastorakis460f57c2014-12-17 00:44:14 -08001692. Basic Permissions.
170---------------------
Alexander Afanasyevf34fe562013-08-09 17:16:12 -0700171
Spyridon Mastorakis460f57c2014-12-17 00:44:14 -0800172All rights granted under this License are granted for the term of copyright on the Program, and are
173irrevocable provided the stated conditions are met. This License explicitly affirms your unlimited
174permission to run the unmodified Program. The output from running a covered work is covered by this
175License only if the output, given its content, constitutes a covered work. This License acknowledges
176your rights of fair use or other equivalent, as provided by copyright law.
Alexander Afanasyevf34fe562013-08-09 17:16:12 -0700177
Spyridon Mastorakis460f57c2014-12-17 00:44:14 -0800178You may make, run and propagate covered works that you do not convey, without conditions so long as
179your license otherwise remains in force. You may convey covered works to others for the sole purpose
180of having them make modifications exclusively for you, or provide you with facilities for running
181those works, provided that you comply with the terms of this License in conveying all material for
182which you do not control copyright. Those thus making or running the covered works for you must do
183so exclusively on your behalf, under your direction and control, on terms that prohibit them from
184making any copies of your copyrighted material outside their relationship with you.
Alexander Afanasyevf34fe562013-08-09 17:16:12 -0700185
Spyridon Mastorakis460f57c2014-12-17 00:44:14 -0800186Conveying under any other circumstances is permitted solely under the conditions stated below.
187Sublicensing is not allowed; section 10 makes it unnecessary.

Spyridon Mastorakis460f57c2014-12-17 00:44:14 -08001893. Protecting Users' Legal Rights From Anti-Circumvention Law.
190--------------------------------------------------------------
Alexander Afanasyevf34fe562013-08-09 17:16:12 -0700191
Spyridon Mastorakis460f57c2014-12-17 00:44:14 -0800192No covered work shall be deemed part of an effective technological measure under any applicable law
193fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or
194similar laws prohibiting or restricting circumvention of such measures.
Alexander Afanasyevf34fe562013-08-09 17:16:12 -0700195
Spyridon Mastorakis460f57c2014-12-17 00:44:14 -0800196When you convey a covered work, you waive any legal power to forbid circumvention of technological
197measures to the extent such circumvention is effected by exercising rights under this License with
198respect to the covered work, and you disclaim any intention to limit operation or modification of
199the work as a means of enforcing, against the work's users, your or third parties' legal rights to
200forbid circumvention of technological measures.
Alexander Afanasyevf34fe562013-08-09 17:16:12 -0700201
Spyridon Mastorakis460f57c2014-12-17 00:44:14 -08002024. Conveying Verbatim Copies.
203-----------------------------
Alexander Afanasyevf34fe562013-08-09 17:16:12 -0700204
Spyridon Mastorakis460f57c2014-12-17 00:44:14 -0800205You may convey verbatim copies of the Program's source code as you receive it, in any medium,
206provided that you conspicuously and appropriately publish on each copy an appropriate copyright
207notice; keep intact all notices stating that this License and any non-permissive terms added in
208accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and
209give all recipients a copy of this License along with the Program.
210
211You may charge any price or no price for each copy that you convey, and you may offer support or
212warranty protection for a fee.
213
2145. Conveying Modified Source Versions.
215--------------------------------------
216
217You may convey a work based on the Program, or the modifications to produce it from the Program, in
218the form of source code under the terms of section 4, provided that you also meet all of these
219conditions:
220
221 a) The work must carry prominent notices stating that you modified
222 it, and giving a relevant date.
223
224 b) The work must carry prominent notices stating that it is
225 released under this License and any conditions added under section
226 7. This requirement modifies the requirement in section 4 to
227 "keep intact all notices".
228
229 c) You must license the entire work, as a whole, under this
230 License to anyone who comes into possession of a copy. This
231 License will therefore apply, along with any applicable section 7
232 additional terms, to the whole of the work, and all its parts,
233 regardless of how they are packaged. This License gives no
234 permission to license the work in any other way, but it does not
235 invalidate such permission if you have separately received it.
236
237 d) If the work has interactive user interfaces, each must display
238 Appropriate Legal Notices; however, if the Program has interactive
239 interfaces that do not display Appropriate Legal Notices, your
240 work need not make them do so.
241
242A compilation of a covered work with other separate and independent works, which are not by their
243nature extensions of the covered work, and which are not combined with it such as to form a larger
244program, in or on a volume of a storage or distribution medium, is called an "aggregate" if the
245compilation and its resulting copyright are not used to limit the access or legal rights of the
246compilation's users beyond what the individual works permit. Inclusion of a covered work in an
247aggregate does not cause this License to apply to the other parts of the aggregate.
248
2496. Conveying Non-Source Forms.
250------------------------------
251
252You may convey a covered work in object code form under the terms of sections 4 and 5, provided that
253you also convey the machine-readable Corresponding Source under the terms of this License, in one of
254these ways:
255
256 a) Convey the object code in, or embodied in, a physical product
257 (including a physical distribution medium), accompanied by the
258 Corresponding Source fixed on a durable physical medium
259 customarily used for software interchange.
260
261 b) Convey the object code in, or embodied in, a physical product
262 (including a physical distribution medium), accompanied by a
263 written offer, valid for at least three years and valid for as
264 long as you offer spare parts or customer support for that product
265 model, to give anyone who possesses the object code either (1) a
266 copy of the Corresponding Source for all the software in the
267 product that is covered by this License, on a durable physical
268 medium customarily used for software interchange, for a price no
269 more than your reasonable cost of physically performing this
270 conveying of source, or (2) access to copy the
271 Corresponding Source from a network server at no charge.
272
273 c) Convey individual copies of the object code with a copy of the
274 written offer to provide the Corresponding Source. This
275 alternative is allowed only occasionally and noncommercially, and
276 only if you received the object code with such an offer, in accord
277 with subsection 6b.
278
279 d) Convey the object code by offering access from a designated
280 place (gratis or for a charge), and offer equivalent access to the
281 Corresponding Source in the same way through the same place at no
282 further charge. You need not require recipients to copy the
283 Corresponding Source along with the object code. If the place to
284 copy the object code is a network server, the Corresponding Source
285 may be on a different server (operated by you or a third party)
286 that supports equivalent copying facilities, provided you maintain
287 clear directions next to the object code saying where to find the
288 Corresponding Source. Regardless of what server hosts the
289 Corresponding Source, you remain obligated to ensure that it is
290 available for as long as needed to satisfy these requirements.
291
292 e) Convey the object code using peer-to-peer transmission, provided
293 you inform other peers where the object code and Corresponding
294 Source of the work are being offered to the general public at no
295 charge under subsection 6d.
296
297A separable portion of the object code, whose source code is excluded from the Corresponding Source
298as a System Library, need not be included in conveying the object code work.
299
300A *"User Product"* is either (1) a *"consumer product"*, which means any tangible personal property
301which is normally used for personal, family, or household purposes, or (2) anything designed or sold
302for incorporation into a dwelling. In determining whether a product is a consumer product, doubtful
303cases shall be resolved in favor of coverage. For a particular product received by a particular
304user, "normally used" refers to a typical or common use of that class of product, regardless of the
305status of the particular user or of the way in which the particular user actually uses, or expects
306or is expected to use, the product. A product is a consumer product regardless of whether the
307product has substantial commercial, industrial or non-consumer uses, unless such uses represent the
308only significant mode of use of the product.
309
310*"Installation Information"* for a User Product means any methods, procedures, authorization keys,
311or other information required to install and execute modified versions of a covered work in that
312User Product from a modified version of its Corresponding Source. The information must suffice to
313ensure that the continued functioning of the modified object code is in no case prevented or
314interfered with solely because modification has been made.
315
316If you convey an object code work under this section in, or with, or specifically for use in, a User
317Product, and the conveying occurs as part of a transaction in which the right of possession and use
318of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of
319how the transaction is characterized), the Corresponding Source conveyed under this section must be
320accompanied by the Installation Information. But this requirement does not apply if neither you nor
321any third party retains the ability to install modified object code on the User Product (for
322example, the work has been installed in ROM).
323
324The requirement to provide Installation Information does not include a requirement to continue to
325provide support service, warranty, or updates for a work that has been modified or installed by the
326recipient, or for the User Product in which it has been modified or installed. Access to a network
327may be denied when the modification itself materially and adversely affects the operation of the
328network or violates the rules and protocols for communication across the network.
329
330Corresponding Source conveyed, and Installation Information provided, in accord with this section
331must be in a format that is publicly documented (and with an implementation available to the public
332in source code form), and must require no special password or key for unpacking, reading or copying.
333
3347. Additional Terms.
335--------------------
336
337*"Additional permissions"* are terms that supplement the terms of this License by making exceptions
338from one or more of its conditions. Additional permissions that are applicable to the entire Program
339shall be treated as though they were included in this License, to the extent that they are valid
340under applicable law. If additional permissions apply only to part of the Program, that part may be
341used separately under those permissions, but the entire Program remains governed by this License
342without regard to the additional permissions.
343
344When you convey a copy of a covered work, you may at your option remove any additional permissions
345from that copy, or from any part of it. (Additional permissions may be written to require their own
346removal in certain cases when you modify the work.) You may place additional permissions on
347material, added by you to a covered work, for which you have or can give appropriate copyright
348permission.
349
350Notwithstanding any other provision of this License, for material you add to a covered work, you may
351(if authorized by the copyright holders of that material) supplement the terms of this License with
352terms:
353
354 a) Disclaiming warranty or limiting liability differently from the
355 terms of sections 15 and 16 of this License; or
356
357 b) Requiring preservation of specified reasonable legal notices or
358 author attributions in that material or in the Appropriate Legal
359 Notices displayed by works containing it; or
360
361 c) Prohibiting misrepresentation of the origin of that material, or
362 requiring that modified versions of such material be marked in
363 reasonable ways as different from the original version; or
364
365 d) Limiting the use for publicity purposes of names of licensors or
366 authors of the material; or
367
368 e) Declining to grant rights under trademark law for use of some
369 trade names, trademarks, or service marks; or
370
371 f) Requiring indemnification of licensors and authors of that
372 material by anyone who conveys the material (or modified versions of
373 it) with contractual assumptions of liability to the recipient, for
374 any liability that these contractual assumptions directly impose on
375 those licensors and authors.
376
377All other non-permissive additional terms are considered "further restrictions" within the meaning
378of section 10. If the Program as you received it, or any part of it, contains a notice stating that
379it is governed by this License along with a term that is a further restriction, you may remove that
380term. If a license document contains a further restriction but permits relicensing or conveying
381under this License, you may add to a covered work material governed by the terms of that license
382document, provided that the further restriction does not survive such relicensing or conveying.
383
384If you add terms to a covered work in accord with this section, you must place, in the relevant
385source files, a statement of the additional terms that apply to those files, or a notice indicating
386where to find the applicable terms.
387
388Additional terms, permissive or non-permissive, may be stated in the form of a separately written
389license, or stated as exceptions; the above requirements apply either way.
390
3918. Termination.
392---------------
393
394You may not propagate or modify a covered work except as expressly provided under this License. Any
395attempt otherwise to propagate or modify it is void, and will automatically terminate your rights
396under this License (including any patent licenses granted under the third paragraph of section 11).
397
398However, if you cease all violation of this License, then your license from a particular copyright
399holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally
400terminates your license, and (b) permanently, if the copyright holder fails to notify you of the
401violation by some reasonable means prior to 60 days after the cessation.
402
403Moreover, your license from a particular copyright holder is reinstated permanently if the copyright
404holder notifies you of the violation by some reasonable means, this is the first time you have
405received notice of violation of this License (for any work) from that copyright holder, and you cure
406the violation prior to 30 days after your receipt of the notice.
407
408Termination of your rights under this section does not terminate the licenses of parties who have
409received copies or rights from you under this License. If your rights have been terminated and not
410permanently reinstated, you do not qualify to receive new licenses for the same material under
411section 10.
412
4139. Acceptance Not Required for Having Copies.
414---------------------------------------------
415
416You are not required to accept this License in order to receive or run a copy of the Program.
417Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer
418transmission to receive a copy likewise does not require acceptance. However, nothing other than
419this License grants you permission to propagate or modify any covered work. These actions infringe
420copyright if you do not accept this License. Therefore, by modifying or propagating a covered work,
421you indicate your acceptance of this License to do so.
422
42310. Automatic Licensing of Downstream Recipients.
424-------------------------------------------------
425
426Each time you convey a covered work, the recipient automatically receives a license from the
427original licensors, to run, modify and propagate that work, subject to this License. You are not
428responsible for enforcing compliance by third parties with this License.
429
430An *"entity transaction"* is a transaction transferring control of an organization, or substantially
431all assets of one, or subdividing an organization, or merging organizations. If propagation of a
432covered work results from an entity transaction, each party to that transaction who receives a copy
433of the work also receives whatever licenses to the work the party's predecessor in interest had or
434could give under the previous paragraph, plus a right to possession of the Corresponding Source of
435the work from the predecessor in interest, if the predecessor has it or can get it with reasonable
436efforts.
437
438You may not impose any further restrictions on the exercise of the rights granted or affirmed under
439this License. For example, you may not impose a license fee, royalty, or other charge for exercise
440of rights granted under this License, and you may not initiate litigation (including a cross-claim
441or counterclaim in a lawsuit) alleging that any patent claim is infringed by making, using, selling,
442offering for sale, or importing the Program or any portion of it.
443
44411. Patents.
445------------
446
447A *"contributor"* is a copyright holder who authorizes use under this License of the Program or a
448work on which the Program is based. The work thus licensed is called the contributor's "contributor
449version".
450
451A contributor's *"essential patent claims"* are all patent claims owned or controlled by the
452contributor, whether already acquired or hereafter acquired, that would be infringed by some manner,
453permitted by this License, of making, using, or selling its contributor version, but do not include
454claims that would be infringed only as a consequence of further modification of the contributor
455version. For purposes of this definition, "control" includes the right to grant patent sublicenses
456in a manner consistent with the requirements of this License.
457
458Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the
459contributor's essential patent claims, to make, use, sell, offer for sale, import and otherwise run,
460modify and propagate the contents of its contributor version.
461
462In the following three paragraphs, a "patent license" is any express agreement or commitment,
463however denominated, not to enforce a patent (such as an express permission to practice a patent or
464covenant not to sue for patent infringement). To "grant" such a patent license to a party means to
465make such an agreement or commitment not to enforce a patent against the party.
466
467If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of
468the work is not available for anyone to copy, free of charge and under the terms of this License,
469through a publicly available network server or other readily accessible means, then you must either
470(1) cause the Corresponding Source to be so available, or (2) arrange to deprive yourself of the
471benefit of the patent license for this particular work, or (3) arrange, in a manner consistent with
472the requirements of this License, to extend the patent license to downstream recipients. "Knowingly
473relying" means you have actual knowledge that, but for the patent license, your conveying the
474covered work in a country, or your recipient's use of the covered work in a country, would infringe
475one or more identifiable patents in that country that you have reason to believe are valid.
476
477If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate
478by procuring conveyance of, a covered work, and grant a patent license to some of the parties
479receiving the covered work authorizing them to use, propagate, modify or convey a specific copy of
480the covered work, then the patent license you grant is automatically extended to all recipients of
481the covered work and works based on it.
482
483A patent license is "discriminatory" if it does not include within the scope of its coverage,
484prohibits the exercise of, or is conditioned on the non-exercise of one or more of the rights that
485are specifically granted under this License. You may not convey a covered work if you are a party to
486an arrangement with a third party that is in the business of distributing software, under which you
487make payment to the third party based on the extent of your activity of conveying the work, and
488under which the third party grants, to any of the parties who would receive the covered work from
489you, a discriminatory patent license (a) in connection with copies of the covered work conveyed by
490you (or copies made from those copies), or (b) primarily for and in connection with specific
491products or compilations that contain the covered work, unless you entered into that arrangement, or
492that patent license was granted, prior to 28 March 2007.
493
494Nothing in this License shall be construed as excluding or limiting any implied license or other
495defenses to infringement that may otherwise be available to you under applicable patent law.
496
49712. No Surrender of Others' Freedom.
498------------------------------------
499
500If conditions are imposed on you (whether by court order, agreement or otherwise) that contradict
501the conditions of this License, they do not excuse you from the conditions of this License. If you
502cannot convey a covered work so as to satisfy simultaneously your obligations under this License and
503any other pertinent obligations, then as a consequence you may not convey it at all. For example, if
504you agree to terms that obligate you to collect a royalty for further conveying from those to whom
505you convey the Program, the only way you could satisfy both those terms and this License would be to
506refrain entirely from conveying the Program.
507
50813. Use with the GNU Affero General Public License.
509---------------------------------------------------
510
511Notwithstanding any other provision of this License, you have permission to link or combine any
512covered work with a work licensed under version 3 of the GNU Affero General Public License into a
513single combined work, and to convey the resulting work. The terms of this License will continue to
514apply to the part which is the covered work, but the special requirements of the GNU Affero General
515Public License, section 13, concerning interaction through a network will apply to the combination
516as such.
517
51814. Revised Versions of this License.
519-------------------------------------
520
521The Free Software Foundation may publish revised and/or new versions of the GNU General Public
522License from time to time. Such new versions will be similar in spirit to the present version, but
523may differ in detail to address new problems or concerns.
524
525Each version is given a distinguishing version number. If the Program specifies that a certain
526numbered version of the GNU General Public License "or any later version" applies to it, you have
527the option of following the terms and conditions either of that numbered version or of any later
528version published by the Free Software Foundation. If the Program does not specify a version number
529of the GNU General Public License, you may choose any version ever published by the Free Software
Alexander Afanasyevf34fe562013-08-09 17:16:12 -0700530Foundation.
531
Spyridon Mastorakis460f57c2014-12-17 00:44:14 -0800532If the Program specifies that a proxy can decide which future versions of the GNU General Public
533License can be used, that proxy's public statement of acceptance of a version permanently authorizes
534you to choose that version for the Program.
Alexander Afanasyevf34fe562013-08-09 17:16:12 -0700535
Spyridon Mastorakis460f57c2014-12-17 00:44:14 -0800536Later license versions may give you additional or different permissions. However, no additional
537obligations are imposed on any author or copyright holder as a result of your choosing to follow a
538later version.
Alexander Afanasyevf34fe562013-08-09 17:16:12 -0700539
Spyridon Mastorakis460f57c2014-12-17 00:44:14 -080054015. Disclaimer of Warranty.
541---------------------------
Alexander Afanasyevf34fe562013-08-09 17:16:12 -0700542
Spyridon Mastorakis460f57c2014-12-17 00:44:14 -0800543THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
544OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS"
545WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
546IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO
547THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU
548ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
Alexander Afanasyevf34fe562013-08-09 17:16:12 -0700549
Spyridon Mastorakis460f57c2014-12-17 00:44:14 -080055016. Limitation of Liability.
551----------------------------
552
553IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR
554ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR
555DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE
556OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
557INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH
558ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
559DAMAGES.
560
56117. Interpretation of Sections 15 and 16.
562-----------------------------------------
563
564If the disclaimer of warranty and limitation of liability provided above cannot be given local legal
565effect according to their terms, reviewing courts shall apply local law that most closely
566approximates an absolute waiver of all civil liability in connection with the Program, unless a
567warranty or assumption of liability accompanies a copy of the Program in return for a fee.
568
569# END OF TERMS AND CONDITIONS

572How to Apply These Terms to Your New Programs
Spyridon Mastorakis460f57c2014-12-17 00:44:14 -0800573=============================================
Alexander Afanasyevf34fe562013-08-09 17:16:12 -0700574
Spyridon Mastorakis460f57c2014-12-17 00:44:14 -0800575If you develop a new program, and you want it to be of the greatest possible use to the public, the
576best way to achieve this is to make it free software which everyone can redistribute and change
577under these terms.
Alexander Afanasyevf34fe562013-08-09 17:16:12 -0700578
Spyridon Mastorakis460f57c2014-12-17 00:44:14 -0800579To do so, attach the following notices to the program. It is safest to attach them to the start of
580each source file to most effectively state the exclusion of warranty; and each file should have at
581least the "copyright" line and a pointer to where the full notice is found.

602
Spyridon Mastorakis460f57c2014-12-17 00:44:14 -0800603If the program does terminal interaction, make it output a short notice like this when it starts in
604an interactive mode:

615would use an "about box".

Spyridon Mastorakis460f57c2014-12-17 00:44:14 -0800617You should also get your employer (if you work as a programmer) or school, if any, to sign a
618"copyright disclaimer" for the program, if necessary. For more information on this, and how to apply
619and follow the GNU GPL, see http://www.gnu.org/licenses/.

Spyridon Mastorakis460f57c2014-12-17 00:44:14 -0800621The GNU General Public License does not permit incorporating your program into proprietary programs.
622If your program is a subroutine library, you may consider it more useful to permit linking
623proprietary applications with the library. If this is what you want to do, use the GNU Lesser
624General Public License instead of this License. But first, please read
