Davide Pesavento16cbadb2018-11-23 13:21:39 -050040### Preamble
41
42The GNU General Public License is a free, copyleft license for
Alexander Afanasyev08eecea2014-03-28 10:23:30 -070043software and other kinds of works.
44
Davide Pesavento16cbadb2018-11-23 13:21:39 -050045The licenses for most software and other practical works are designed
46to take away your freedom to share and change the works. By contrast,
47the GNU General Public License is intended to guarantee your freedom
48to share and change all versions of a program--to make sure it remains
49free software for all its users. We, the Free Software Foundation, use
50the GNU General Public License for most of our software; it applies
51also to any other work released this way by its authors. You can apply
52it to your programs, too.
Alexander Afanasyev08eecea2014-03-28 10:23:30 -070053
Davide Pesavento16cbadb2018-11-23 13:21:39 -050054When we speak of free software, we are referring to freedom, not
55price. Our General Public Licenses are designed to make sure that you
Alexander Afanasyev08eecea2014-03-28 10:23:30 -070056have the freedom to distribute copies of free software (and charge for
57them if you wish), that you receive source code or can get it if you
58want it, that you can change the software or use pieces of it in new
59free programs, and that you know you can do these things.
60
Davide Pesavento16cbadb2018-11-23 13:21:39 -050061To protect your rights, we need to prevent others from denying you
62these rights or asking you to surrender the rights. Therefore, you
63have certain responsibilities if you distribute copies of the
64software, or if you modify it: responsibilities to respect the freedom
65of others.
Alexander Afanasyev08eecea2014-03-28 10:23:30 -070066
Davide Pesavento16cbadb2018-11-23 13:21:39 -050067For example, if you distribute copies of such a program, whether
Alexander Afanasyev08eecea2014-03-28 10:23:30 -070068gratis or for a fee, you must pass on to the recipients the same
Davide Pesavento16cbadb2018-11-23 13:21:39 -050069freedoms that you received. You must make sure that they, too, receive
70or can get the source code. And you must show them these terms so they
Alexander Afanasyev08eecea2014-03-28 10:23:30 -070071know their rights.
72
Davide Pesavento16cbadb2018-11-23 13:21:39 -050073Developers that use the GNU GPL protect your rights with two steps:
Alexander Afanasyev08eecea2014-03-28 10:23:30 -070074(1) assert copyright on the software, and (2) offer you this License
75giving you legal permission to copy, distribute and/or modify it.
76
Davide Pesavento16cbadb2018-11-23 13:21:39 -050077For the developers' and authors' protection, the GPL clearly explains
78that there is no warranty for this free software. For both users' and
Alexander Afanasyev08eecea2014-03-28 10:23:30 -070079authors' sake, the GPL requires that modified versions be marked as
80changed, so that their problems will not be attributed erroneously to
81authors of previous versions.
82
Davide Pesavento16cbadb2018-11-23 13:21:39 -050083Some devices are designed to deny users access to install or run
84modified versions of the software inside them, although the
85manufacturer can do so. This is fundamentally incompatible with the
86aim of protecting users' freedom to change the software. The
87systematic pattern of such abuse occurs in the area of products for
88individuals to use, which is precisely where it is most unacceptable.
89Therefore, we have designed this version of the GPL to prohibit the
90practice for those products. If such problems arise substantially in
91other domains, we stand ready to extend this provision to those
92domains in future versions of the GPL, as needed to protect the
93freedom of users.
Alexander Afanasyev08eecea2014-03-28 10:23:30 -070094
Davide Pesavento16cbadb2018-11-23 13:21:39 -050095Finally, every program is threatened constantly by software patents.
Alexander Afanasyev08eecea2014-03-28 10:23:30 -070096States should not allow patents to restrict development and use of
Davide Pesavento16cbadb2018-11-23 13:21:39 -050097software on general-purpose computers, but in those that do, we wish
98to avoid the special danger that patents applied to a free program
99could make it effectively proprietary. To prevent this, the GPL
100assures that patents cannot be used to render the program non-free.
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700101
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500102The precise terms and conditions for copying, distribution and
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700103modification follow.
104
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500105### TERMS AND CONDITIONS
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700106
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500107#### 0. Definitions.
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700108
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500109"This License" refers to version 3 of the GNU General Public License.
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700110
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500111"Copyright" also means copyright-like laws that apply to other kinds
112of works, such as semiconductor masks.
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700113
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500114"The Program" refers to any copyrightable work licensed under this
115License. Each licensee is addressed as "you". "Licensees" and
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700116"recipients" may be individuals or organizations.
117
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500118To "modify" a work means to copy from or adapt all or part of the work
119in a fashion requiring copyright permission, other than the making of
120an exact copy. The resulting work is called a "modified version" of
121the earlier work or a work "based on" the earlier work.
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700122
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500123A "covered work" means either the unmodified Program or a work based
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700124on the Program.
125
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500126To "propagate" a work means to do anything with it that, without
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700127permission, would make you directly or secondarily liable for
128infringement under applicable copyright law, except executing it on a
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500129computer or modifying a private copy. Propagation includes copying,
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700130distribution (with or without modification), making available to the
131public, and in some countries other activities as well.
132
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500133To "convey" a work means any kind of propagation that enables other
134parties to make or receive copies. Mere interaction with a user
135through a computer network, with no transfer of a copy, is not
136conveying.
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700137
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500138An interactive user interface displays "Appropriate Legal Notices" to
139the extent that it includes a convenient and prominently visible
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700140feature that (1) displays an appropriate copyright notice, and (2)
141tells the user that there is no warranty for the work (except to the
142extent that warranties are provided), that licensees may convey the
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500143work under this License, and how to view a copy of this License. If
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700144the interface presents a list of user commands or options, such as a
145menu, a prominent item in the list meets this criterion.
146
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500147#### 1. Source Code.
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700148
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500149The "source code" for a work means the preferred form of the work for
150making modifications to it. "Object code" means any non-source form of
151a work.
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700152
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500153A "Standard Interface" means an interface that either is an official
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700154standard defined by a recognized standards body, or, in the case of
155interfaces specified for a particular programming language, one that
156is widely used among developers working in that language.
157
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500158The "System Libraries" of an executable work include anything, other
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700159than the work as a whole, that (a) is included in the normal form of
160packaging a Major Component, but which is not part of that Major
161Component, and (b) serves only to enable use of the work with that
162Major Component, or to implement a Standard Interface for which an
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500163implementation is available to the public in source code form. A
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700164"Major Component", in this context, means a major essential component
165(kernel, window system, and so on) of the specific operating system
166(if any) on which the executable work runs, or a compiler used to
167produce the work, or an object code interpreter used to run it.
168
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500169The "Corresponding Source" for a work in object code form means all
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700170the source code needed to generate, install, and (for an executable
171work) run the object code and to modify the work, including scripts to
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500172control those activities. However, it does not include the work's
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700173System Libraries, or general-purpose tools or generally available free
174programs which are used unmodified in performing those activities but
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500175which are not part of the work. For example, Corresponding Source
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700176includes interface definition files associated with source files for
177the work, and the source code for shared libraries and dynamically
178linked subprograms that the work is specifically designed to require,
179such as by intimate data communication or control flow between those
180subprograms and other parts of the work.
181
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500182The Corresponding Source need not include anything that users can
183regenerate automatically from other parts of the Corresponding Source.
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700184
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500185The Corresponding Source for a work in source code form is that same
186work.
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700187
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500188#### 2. Basic Permissions.
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700189
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500190All rights granted under this License are granted for the term of
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700191copyright on the Program, and are irrevocable provided the stated
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500192conditions are met. This License explicitly affirms your unlimited
193permission to run the unmodified Program. The output from running a
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700194covered work is covered by this License only if the output, given its
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500195content, constitutes a covered work. This License acknowledges your
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700196rights of fair use or other equivalent, as provided by copyright law.
197
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500198You may make, run and propagate covered works that you do not convey,
199without conditions so long as your license otherwise remains in force.
200You may convey covered works to others for the sole purpose of having
201them make modifications exclusively for you, or provide you with
202facilities for running those works, provided that you comply with the
203terms of this License in conveying all material for which you do not
204control copyright. Those thus making or running the covered works for
205you must do so exclusively on your behalf, under your direction and
206control, on terms that prohibit them from making any copies of your
207copyrighted material outside their relationship with you.
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700208
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500209Conveying under any other circumstances is permitted solely under the
210conditions stated below. Sublicensing is not allowed; section 10 makes
211it unnecessary.
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700212
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500213#### 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700214
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500215No covered work shall be deemed part of an effective technological
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700216measure under any applicable law fulfilling obligations under article
21711 of the WIPO copyright treaty adopted on 20 December 1996, or
218similar laws prohibiting or restricting circumvention of such
219measures.
220
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500221When you convey a covered work, you waive any legal power to forbid
222circumvention of technological measures to the extent such
223circumvention is effected by exercising rights under this License with
224respect to the covered work, and you disclaim any intention to limit
225operation or modification of the work as a means of enforcing, against
226the work's users, your or third parties' legal rights to forbid
227circumvention of technological measures.
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700228
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500229#### 4. Conveying Verbatim Copies.
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700230
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500231You may convey verbatim copies of the Program's source code as you
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700232receive it, in any medium, provided that you conspicuously and
233appropriately publish on each copy an appropriate copyright notice;
234keep intact all notices stating that this License and any
235non-permissive terms added in accord with section 7 apply to the code;
236keep intact all notices of the absence of any warranty; and give all
237recipients a copy of this License along with the Program.
238
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500239You may charge any price or no price for each copy that you convey,
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700240and you may offer support or warranty protection for a fee.
241
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500242#### 5. Conveying Modified Source Versions.
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700243
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500244You may convey a work based on the Program, or the modifications to
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700245produce it from the Program, in the form of source code under the
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500246terms of section 4, provided that you also meet all of these
247conditions:
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700248
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500249- a) The work must carry prominent notices stating that you modified
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700250 it, and giving a relevant date.
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500251- b) The work must carry prominent notices stating that it is
252 released under this License and any conditions added under
253 section 7. This requirement modifies the requirement in section 4
254 to "keep intact all notices".
255- c) You must license the entire work, as a whole, under this
256 License to anyone who comes into possession of a copy. This
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700257 License will therefore apply, along with any applicable section 7
258 additional terms, to the whole of the work, and all its parts,
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500259 regardless of how they are packaged. This License gives no
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700260 permission to license the work in any other way, but it does not
261 invalidate such permission if you have separately received it.
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500262- d) If the work has interactive user interfaces, each must display
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700263 Appropriate Legal Notices; however, if the Program has interactive
264 interfaces that do not display Appropriate Legal Notices, your
265 work need not make them do so.
266
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500267A compilation of a covered work with other separate and independent
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700268works, which are not by their nature extensions of the covered work,
269and which are not combined with it such as to form a larger program,
270in or on a volume of a storage or distribution medium, is called an
271"aggregate" if the compilation and its resulting copyright are not
272used to limit the access or legal rights of the compilation's users
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500273beyond what the individual works permit. Inclusion of a covered work
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700274in an aggregate does not cause this License to apply to the other
275parts of the aggregate.
276
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500277#### 6. Conveying Non-Source Forms.
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700278
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500279You may convey a covered work in object code form under the terms of
280sections 4 and 5, provided that you also convey the machine-readable
281Corresponding Source under the terms of this License, in one of these
282ways:
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700283
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500284- a) Convey the object code in, or embodied in, a physical product
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700285 (including a physical distribution medium), accompanied by the
286 Corresponding Source fixed on a durable physical medium
287 customarily used for software interchange.
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500288- b) Convey the object code in, or embodied in, a physical product
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700289 (including a physical distribution medium), accompanied by a
290 written offer, valid for at least three years and valid for as
291 long as you offer spare parts or customer support for that product
292 model, to give anyone who possesses the object code either (1) a
293 copy of the Corresponding Source for all the software in the
294 product that is covered by this License, on a durable physical
295 medium customarily used for software interchange, for a price no
296 more than your reasonable cost of physically performing this
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500297 conveying of source, or (2) access to copy the Corresponding
298 Source from a network server at no charge.
299- c) Convey individual copies of the object code with a copy of the
300 written offer to provide the Corresponding Source. This
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700301 alternative is allowed only occasionally and noncommercially, and
302 only if you received the object code with such an offer, in accord
303 with subsection 6b.
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500304- d) Convey the object code by offering access from a designated
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700305 place (gratis or for a charge), and offer equivalent access to the
306 Corresponding Source in the same way through the same place at no
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500307 further charge. You need not require recipients to copy the
308 Corresponding Source along with the object code. If the place to
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700309 copy the object code is a network server, the Corresponding Source
310 may be on a different server (operated by you or a third party)
311 that supports equivalent copying facilities, provided you maintain
312 clear directions next to the object code saying where to find the
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500313 Corresponding Source. Regardless of what server hosts the
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700314 Corresponding Source, you remain obligated to ensure that it is
315 available for as long as needed to satisfy these requirements.
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500316- e) Convey the object code using peer-to-peer transmission,
317 provided you inform other peers where the object code and
318 Corresponding Source of the work are being offered to the general
319 public at no charge under subsection 6d.
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700320
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500321A separable portion of the object code, whose source code is excluded
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700322from the Corresponding Source as a System Library, need not be
323included in conveying the object code work.
324
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500325A "User Product" is either (1) a "consumer product", which means any
326tangible personal property which is normally used for personal,
327family, or household purposes, or (2) anything designed or sold for
328incorporation into a dwelling. In determining whether a product is a
329consumer product, doubtful cases shall be resolved in favor of
330coverage. For a particular product received by a particular user,
331"normally used" refers to a typical or common use of that class of
332product, regardless of the status of the particular user or of the way
333in which the particular user actually uses, or expects or is expected
334to use, the product. A product is a consumer product regardless of
335whether the product has substantial commercial, industrial or
336non-consumer uses, unless such uses represent the only significant
337mode of use of the product.
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700338
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500339"Installation Information" for a User Product means any methods,
340procedures, authorization keys, or other information required to
341install and execute modified versions of a covered work in that User
342Product from a modified version of its Corresponding Source. The
343information must suffice to ensure that the continued functioning of
344the modified object code is in no case prevented or interfered with
345solely because modification has been made.
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700346
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500347If you convey an object code work under this section in, or with, or
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700348specifically for use in, a User Product, and the conveying occurs as
349part of a transaction in which the right of possession and use of the
350User Product is transferred to the recipient in perpetuity or for a
351fixed term (regardless of how the transaction is characterized), the
352Corresponding Source conveyed under this section must be accompanied
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500353by the Installation Information. But this requirement does not apply
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700354if neither you nor any third party retains the ability to install
355modified object code on the User Product (for example, the work has
356been installed in ROM).
357
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500358The requirement to provide Installation Information does not include a
359requirement to continue to provide support service, warranty, or
360updates for a work that has been modified or installed by the
361recipient, or for the User Product in which it has been modified or
362installed. Access to a network may be denied when the modification
363itself materially and adversely affects the operation of the network
364or violates the rules and protocols for communication across the
365network.
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700366
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500367Corresponding Source conveyed, and Installation Information provided,
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700368in accord with this section must be in a format that is publicly
369documented (and with an implementation available to the public in
370source code form), and must require no special password or key for
371unpacking, reading or copying.
372
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500373#### 7. Additional Terms.
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700374
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500375"Additional permissions" are terms that supplement the terms of this
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700376License by making exceptions from one or more of its conditions.
377Additional permissions that are applicable to the entire Program shall
378be treated as though they were included in this License, to the extent
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500379that they are valid under applicable law. If additional permissions
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700380apply only to part of the Program, that part may be used separately
381under those permissions, but the entire Program remains governed by
382this License without regard to the additional permissions.
383
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500384When you convey a copy of a covered work, you may at your option
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700385remove any additional permissions from that copy, or from any part of
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500386it. (Additional permissions may be written to require their own
387removal in certain cases when you modify the work.) You may place
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700388additional permissions on material, added by you to a covered work,
389for which you have or can give appropriate copyright permission.
390
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500391Notwithstanding any other provision of this License, for material you
392add to a covered work, you may (if authorized by the copyright holders
393of that material) supplement the terms of this License with terms:
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700394
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500395- a) Disclaiming warranty or limiting liability differently from the
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700396 terms of sections 15 and 16 of this License; or
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500397- b) Requiring preservation of specified reasonable legal notices or
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700398 author attributions in that material or in the Appropriate Legal
399 Notices displayed by works containing it; or
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500400- c) Prohibiting misrepresentation of the origin of that material,
401 or requiring that modified versions of such material be marked in
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700402 reasonable ways as different from the original version; or
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500403- d) Limiting the use for publicity purposes of names of licensors
404 or authors of the material; or
405- e) Declining to grant rights under trademark law for use of some
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700406 trade names, trademarks, or service marks; or
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500407- f) Requiring indemnification of licensors and authors of that
408 material by anyone who conveys the material (or modified versions
409 of it) with contractual assumptions of liability to the recipient,
410 for any liability that these contractual assumptions directly
411 impose on those licensors and authors.
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700412
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500413All other non-permissive additional terms are considered "further
414restrictions" within the meaning of section 10. If the Program as you
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700415received it, or any part of it, contains a notice stating that it is
416governed by this License along with a term that is a further
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500417restriction, you may remove that term. If a license document contains
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700418a further restriction but permits relicensing or conveying under this
419License, you may add to a covered work material governed by the terms
420of that license document, provided that the further restriction does
421not survive such relicensing or conveying.
422
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500423If you add terms to a covered work in accord with this section, you
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700424must place, in the relevant source files, a statement of the
425additional terms that apply to those files, or a notice indicating
426where to find the applicable terms.
427
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500428Additional terms, permissive or non-permissive, may be stated in the
429form of a separately written license, or stated as exceptions; the
430above requirements apply either way.
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700431
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500432#### 8. Termination.
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700433
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500434You may not propagate or modify a covered work except as expressly
435provided under this License. Any attempt otherwise to propagate or
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700436modify it is void, and will automatically terminate your rights under
437this License (including any patent licenses granted under the third
438paragraph of section 11).
439
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500440However, if you cease all violation of this License, then your license
441from a particular copyright holder is reinstated (a) provisionally,
442unless and until the copyright holder explicitly and finally
443terminates your license, and (b) permanently, if the copyright holder
444fails to notify you of the violation by some reasonable means prior to
44560 days after the cessation.
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700446
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500447Moreover, your license from a particular copyright holder is
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700448reinstated permanently if the copyright holder notifies you of the
449violation by some reasonable means, this is the first time you have
450received notice of violation of this License (for any work) from that
451copyright holder, and you cure the violation prior to 30 days after
452your receipt of the notice.
453
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500454Termination of your rights under this section does not terminate the
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700455licenses of parties who have received copies or rights from you under
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500456this License. If your rights have been terminated and not permanently
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700457reinstated, you do not qualify to receive new licenses for the same
458material under section 10.
459
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500460#### 9. Acceptance Not Required for Having Copies.
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700461
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500462You are not required to accept this License in order to receive or run
463a copy of the Program. Ancillary propagation of a covered work
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700464occurring solely as a consequence of using peer-to-peer transmission
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500465to receive a copy likewise does not require acceptance. However,
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700466nothing other than this License grants you permission to propagate or
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500467modify any covered work. These actions infringe copyright if you do
468not accept this License. Therefore, by modifying or propagating a
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700469covered work, you indicate your acceptance of this License to do so.
470
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500471#### 10. Automatic Licensing of Downstream Recipients.
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700472
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500473Each time you convey a covered work, the recipient automatically
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700474receives a license from the original licensors, to run, modify and
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500475propagate that work, subject to this License. You are not responsible
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700476for enforcing compliance by third parties with this License.
477
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500478An "entity transaction" is a transaction transferring control of an
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700479organization, or substantially all assets of one, or subdividing an
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500480organization, or merging organizations. If propagation of a covered
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700481work results from an entity transaction, each party to that
482transaction who receives a copy of the work also receives whatever
483licenses to the work the party's predecessor in interest had or could
484give under the previous paragraph, plus a right to possession of the
485Corresponding Source of the work from the predecessor in interest, if
486the predecessor has it or can get it with reasonable efforts.
487
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500488You may not impose any further restrictions on the exercise of the
489rights granted or affirmed under this License. For example, you may
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700490not impose a license fee, royalty, or other charge for exercise of
491rights granted under this License, and you may not initiate litigation
492(including a cross-claim or counterclaim in a lawsuit) alleging that
493any patent claim is infringed by making, using, selling, offering for
494sale, or importing the Program or any portion of it.
495
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500496#### 11. Patents.
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700497
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500498A "contributor" is a copyright holder who authorizes use under this
499License of the Program or a work on which the Program is based. The
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700500work thus licensed is called the contributor's "contributor version".
501
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500502A contributor's "essential patent claims" are all patent claims owned
503or controlled by the contributor, whether already acquired or
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700504hereafter acquired, that would be infringed by some manner, permitted
505by this License, of making, using, or selling its contributor version,
506but do not include claims that would be infringed only as a
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500507consequence of further modification of the contributor version. For
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700508purposes of this definition, "control" includes the right to grant
509patent sublicenses in a manner consistent with the requirements of
510this License.
511
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500512Each contributor grants you a non-exclusive, worldwide, royalty-free
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700513patent license under the contributor's essential patent claims, to
514make, use, sell, offer for sale, import and otherwise run, modify and
515propagate the contents of its contributor version.
516
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500517In the following three paragraphs, a "patent license" is any express
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700518agreement or commitment, however denominated, not to enforce a patent
519(such as an express permission to practice a patent or covenant not to
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500520sue for patent infringement). To "grant" such a patent license to a
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700521party means to make such an agreement or commitment not to enforce a
522patent against the party.
523
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500524If you convey a covered work, knowingly relying on a patent license,
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700525and the Corresponding Source of the work is not available for anyone
526to copy, free of charge and under the terms of this License, through a
527publicly available network server or other readily accessible means,
528then you must either (1) cause the Corresponding Source to be so
529available, or (2) arrange to deprive yourself of the benefit of the
530patent license for this particular work, or (3) arrange, in a manner
531consistent with the requirements of this License, to extend the patent
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500532license to downstream recipients. "Knowingly relying" means you have
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700533actual knowledge that, but for the patent license, your conveying the
534covered work in a country, or your recipient's use of the covered work
535in a country, would infringe one or more identifiable patents in that
536country that you have reason to believe are valid.
537
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500538If, pursuant to or in connection with a single transaction or
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700539arrangement, you convey, or propagate by procuring conveyance of, a
540covered work, and grant a patent license to some of the parties
541receiving the covered work authorizing them to use, propagate, modify
542or convey a specific copy of the covered work, then the patent license
543you grant is automatically extended to all recipients of the covered
544work and works based on it.
545
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500546A patent license is "discriminatory" if it does not include within the
547scope of its coverage, prohibits the exercise of, or is conditioned on
548the non-exercise of one or more of the rights that are specifically
549granted under this License. You may not convey a covered work if you
550are a party to an arrangement with a third party that is in the
551business of distributing software, under which you make payment to the
552third party based on the extent of your activity of conveying the
553work, and under which the third party grants, to any of the parties
554who would receive the covered work from you, a discriminatory patent
555license (a) in connection with copies of the covered work conveyed by
556you (or copies made from those copies), or (b) primarily for and in
557connection with specific products or compilations that contain the
558covered work, unless you entered into that arrangement, or that patent
559license was granted, prior to 28 March 2007.

Davide Pesavento16cbadb2018-11-23 13:21:39 -0500561Nothing in this License shall be construed as excluding or limiting
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700562any implied license or other defenses to infringement that may
563otherwise be available to you under applicable patent law.

Davide Pesavento16cbadb2018-11-23 13:21:39 -0500565#### 12. No Surrender of Others' Freedom.
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700566
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500567If conditions are imposed on you (whether by court order, agreement or
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700568otherwise) that contradict the conditions of this License, they do not
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500569excuse you from the conditions of this License. If you cannot convey a
570covered work so as to satisfy simultaneously your obligations under
571this License and any other pertinent obligations, then as a
572consequence you may not convey it at all. For example, if you agree to
573terms that obligate you to collect a royalty for further conveying
574from those to whom you convey the Program, the only way you could
575satisfy both those terms and this License would be to refrain entirely
576from conveying the Program.
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700577
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500578#### 13. Use with the GNU Affero General Public License.
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700579
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500580Notwithstanding any other provision of this License, you have
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700581permission to link or combine any covered work with a work licensed
582under version 3 of the GNU Affero General Public License into a single
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500583combined work, and to convey the resulting work. The terms of this
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700584License will continue to apply to the part which is the covered work,
585but the special requirements of the GNU Affero General Public License,
586section 13, concerning interaction through a network will apply to the
587combination as such.
588
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500589#### 14. Revised Versions of this License.
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700590
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500591The Free Software Foundation may publish revised and/or new versions
592of the GNU General Public License from time to time. Such new versions
593will be similar in spirit to the present version, but may differ in
594detail to address new problems or concerns.
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700595
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500596Each version is given a distinguishing version number. If the Program
597specifies that a certain numbered version of the GNU General Public
598License "or any later version" applies to it, you have the option of
599following the terms and conditions either of that numbered version or
600of any later version published by the Free Software Foundation. If the
601Program does not specify a version number of the GNU General Public
602License, you may choose any version ever published by the Free
603Software Foundation.
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700604
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500605If the Program specifies that a proxy can decide which future versions
606of the GNU General Public License can be used, that proxy's public
607statement of acceptance of a version permanently authorizes you to
608choose that version for the Program.
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700609
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500610Later license versions may give you additional or different
611permissions. However, no additional obligations are imposed on any
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700612author or copyright holder as a result of your choosing to follow a
613later version.
614
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500615#### 15. Disclaimer of Warranty.
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700616
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500617THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
618APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
619HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT
620WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT
621LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR
622A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND
623PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE
624DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
625CORRECTION.
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700626
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500627#### 16. Limitation of Liability.
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700628
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500629IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
630WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR
631CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
632INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES
633ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT
634NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR
635LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM
636TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER
637PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

Davide Pesavento16cbadb2018-11-23 13:21:39 -0500639#### 17. Interpretation of Sections 15 and 16.
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700640
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500641If the disclaimer of warranty and limitation of liability provided
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700642above cannot be given local legal effect according to their terms,
643reviewing courts shall apply local law that most closely approximates
644an absolute waiver of all civil liability in connection with the
645Program, unless a warranty or assumption of liability accompanies a
646copy of the Program in return for a fee.

Davide Pesavento16cbadb2018-11-23 13:21:39 -0500650### How to Apply These Terms to Your New Programs
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700651
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500652If you develop a new program, and you want it to be of the greatest
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700653possible use to the public, the best way to achieve this is to make it
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500654free software which everyone can redistribute and change under these
655terms.
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700656
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500657To do so, attach the following notices to the program. It is safest to
658attach them to the start of each source file to most effectively state
659the exclusion of warranty; and each file should have at least the
660"copyright" line and a pointer to where the full notice is found.
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700661

Davide Pesavento16cbadb2018-11-23 13:21:39 -0500681If the program does terminal interaction, make it output a short
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700682notice like this when it starts in an interactive mode:

Davide Pesavento16cbadb2018-11-23 13:21:39 -0500689The hypothetical commands \`show w' and \`show c' should show the
690appropriate parts of the General Public License. Of course, your
691program's commands might be different; for a GUI interface, you would
692use an "about box".
Alexander Afanasyev08eecea2014-03-28 10:23:30 -0700693
Davide Pesavento16cbadb2018-11-23 13:21:39 -0500694You should also get your employer (if you work as a programmer) or

696necessary. For more information on this, and how to apply and follow
697the GNU GPL, see <https://www.gnu.org/licenses/>.
