Davide Pesavento1fd00242018-05-20 00:11:01 -040057As used herein, "this License" refers to version 3 of the GNU Lesser
58General Public License, and the "GNU GPL" refers to version 3 of the
59GNU General Public License.
Alexander Afanasyevc169a812014-05-20 20:37:29 -040060
Davide Pesavento1fd00242018-05-20 00:11:01 -040061"The Library" refers to a covered work governed by this License, other
62than an Application or a Combined Work as defined below.
Alexander Afanasyevc169a812014-05-20 20:37:29 -040063
Davide Pesavento1fd00242018-05-20 00:11:01 -040064An "Application" is any work that makes use of an interface provided
Alexander Afanasyevc169a812014-05-20 20:37:29 -040065by the Library, but which is not otherwise based on the Library.
66Defining a subclass of a class defined by the Library is deemed a mode
67of using an interface provided by the Library.
68
Davide Pesavento1fd00242018-05-20 00:11:01 -040069A "Combined Work" is a work produced by combining or linking an
70Application with the Library. The particular version of the Library
71with which the Combined Work was made is also called the "Linked
72Version".
Alexander Afanasyevc169a812014-05-20 20:37:29 -040073
Davide Pesavento1fd00242018-05-20 00:11:01 -040074The "Minimal Corresponding Source" for a Combined Work means the
Alexander Afanasyevc169a812014-05-20 20:37:29 -040075Corresponding Source for the Combined Work, excluding any source code
76for portions of the Combined Work that, considered in isolation, are
77based on the Application, and not on the Linked Version.
78
Davide Pesavento1fd00242018-05-20 00:11:01 -040079The "Corresponding Application Code" for a Combined Work means the
Alexander Afanasyevc169a812014-05-20 20:37:29 -040080object code and/or source code for the Application, including any data
81and utility programs needed for reproducing the Combined Work from the
82Application, but excluding the System Libraries of the Combined Work.
83
Davide Pesavento1fd00242018-05-20 00:11:01 -040084#### 1. Exception to Section 3 of the GNU GPL.
Alexander Afanasyevc169a812014-05-20 20:37:29 -040085
86You may convey a covered work under sections 3 and 4 of this License
87without being bound by section 3 of the GNU GPL.
88
Davide Pesavento1fd00242018-05-20 00:11:01 -040089#### 2. Conveying Modified Versions.
Alexander Afanasyevc169a812014-05-20 20:37:29 -040090
91If you modify a copy of the Library, and, in your modifications, a
92facility refers to a function or data to be supplied by an Application
93that uses the facility (other than as an argument passed when the
94facility is invoked), then you may convey a copy of the modified
95version:
96
Davide Pesavento1fd00242018-05-20 00:11:01 -040097- a) under this License, provided that you make a good faith effort
98 to ensure that, in the event an Application does not supply the
99 function or data, the facility still operates, and performs
100 whatever part of its purpose remains meaningful, or
101- b) under the GNU GPL, with none of the additional permissions of
102 this License applicable to that copy.
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400103
Davide Pesavento1fd00242018-05-20 00:11:01 -0400104#### 3. Object Code Incorporating Material from Library Header Files.
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400105
Davide Pesavento1fd00242018-05-20 00:11:01 -0400106The object code form of an Application may incorporate material from a
107header file that is part of the Library. You may convey such object
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400108code under terms of your choice, provided that, if the incorporated
109material is not limited to numerical parameters, data structure
110layouts and accessors, or small macros, inline functions and templates
111(ten or fewer lines in length), you do both of the following:
112
Davide Pesavento1fd00242018-05-20 00:11:01 -0400113- a) Give prominent notice with each copy of the object code that
114 the Library is used in it and that the Library and its use are
115 covered by this License.
116- b) Accompany the object code with a copy of the GNU GPL and this
117 license document.

Alexander Afanasyevc169a812014-05-20 20:37:29 -0400120
Davide Pesavento1fd00242018-05-20 00:11:01 -0400121You may convey a Combined Work under terms of your choice that, taken
122together, effectively do not restrict modification of the portions of
123the Library contained in the Combined Work and reverse engineering for
124debugging such modifications, if you also do each of the following:
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400125
Davide Pesavento1fd00242018-05-20 00:11:01 -0400126- a) Give prominent notice with each copy of the Combined Work that
127 the Library is used in it and that the Library and its use are
128 covered by this License.
129- b) Accompany the Combined Work with a copy of the GNU GPL and this
130 license document.
131- c) For a Combined Work that displays copyright notices during
132 execution, include the copyright notice for the Library among
133 these notices, as well as a reference directing the user to the
134 copies of the GNU GPL and this license document.
135- d) Do one of the following:
136 - 0) Convey the Minimal Corresponding Source under the terms of
137 this License, and the Corresponding Application Code in a form
138 suitable for, and under terms that permit, the user to
139 recombine or relink the Application with a modified version of
140 the Linked Version to produce a modified Combined Work, in the
141 manner specified by section 6 of the GNU GPL for conveying
142 Corresponding Source.
143 - 1) Use a suitable shared library mechanism for linking with
144 the Library. A suitable mechanism is one that (a) uses at run
145 time a copy of the Library already present on the user's
146 computer system, and (b) will operate properly with a modified
147 version of the Library that is interface-compatible with the
148 Linked Version.
149- e) Provide Installation Information, but only if you would
150 otherwise be required to provide such information under section 6
151 of the GNU GPL, and only to the extent that such information is
152 necessary to install and execute a modified version of the
153 Combined Work produced by recombining or relinking the Application
154 with a modified version of the Linked Version. (If you use option
155 4d0, the Installation Information must accompany the Minimal
156 Corresponding Source and Corresponding Application Code. If you
157 use option 4d1, you must provide the Installation Information in
158 the manner specified by section 6 of the GNU GPL for conveying
159 Corresponding Source.)

Alexander Afanasyevc169a812014-05-20 20:37:29 -0400162
Davide Pesavento1fd00242018-05-20 00:11:01 -0400163You may place library facilities that are a work based on the Library
164side by side in a single library together with other library
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400165facilities that are not Applications and are not covered by this
166License, and convey such a combined library under terms of your
167choice, if you do both of the following:
168
Davide Pesavento1fd00242018-05-20 00:11:01 -0400169- a) Accompany the combined library with a copy of the same work
170 based on the Library, uncombined with any other library
171 facilities, conveyed under the terms of this License.
172- b) Give prominent notice with the combined library that part of it
173 is a work based on the Library, and explaining where to find the
174 accompanying uncombined form of the same work.

Davide Pesavento1fd00242018-05-20 00:11:01 -0400176#### 6. Revised Versions of the GNU Lesser General Public License.
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400177
178The Free Software Foundation may publish revised and/or new versions
179of the GNU Lesser General Public License from time to time. Such new
180versions will be similar in spirit to the present version, but may
181differ in detail to address new problems or concerns.
182
Davide Pesavento1fd00242018-05-20 00:11:01 -0400183Each version is given a distinguishing version number. If the Library
184as you received it specifies that a certain numbered version of the
185GNU Lesser General Public License "or any later version" applies to
186it, you have the option of following the terms and conditions either
187of that published version or of any later version published by the
188Free Software Foundation. If the Library as you received it does not
189specify a version number of the GNU Lesser General Public License, you
190may choose any version of the GNU Lesser General Public License ever
191published by the Free Software Foundation.
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400192
193If the Library as you received it specifies that a proxy can decide
194whether future versions of the GNU Lesser General Public License shall
195apply, that proxy's public statement of acceptance of any version is
196permanent authorization for you to choose that version for the
197Library.

Davide Pesavento1fd00242018-05-20 00:11:01 -0400211### Preamble
212
213The GNU General Public License is a free, copyleft license for
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400214software and other kinds of works.
215
Davide Pesavento1fd00242018-05-20 00:11:01 -0400216The licenses for most software and other practical works are designed
217to take away your freedom to share and change the works. By contrast,
218the GNU General Public License is intended to guarantee your freedom
219to share and change all versions of a program--to make sure it remains
220free software for all its users. We, the Free Software Foundation, use
221the GNU General Public License for most of our software; it applies
222also to any other work released this way by its authors. You can apply
223it to your programs, too.
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400224
Davide Pesavento1fd00242018-05-20 00:11:01 -0400225When we speak of free software, we are referring to freedom, not
226price. Our General Public Licenses are designed to make sure that you
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400227have the freedom to distribute copies of free software (and charge for
228them if you wish), that you receive source code or can get it if you
229want it, that you can change the software or use pieces of it in new
230free programs, and that you know you can do these things.
231
Davide Pesavento1fd00242018-05-20 00:11:01 -0400232To protect your rights, we need to prevent others from denying you
233these rights or asking you to surrender the rights. Therefore, you
234have certain responsibilities if you distribute copies of the
235software, or if you modify it: responsibilities to respect the freedom
236of others.
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400237
Davide Pesavento1fd00242018-05-20 00:11:01 -0400238For example, if you distribute copies of such a program, whether
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400239gratis or for a fee, you must pass on to the recipients the same
Davide Pesavento1fd00242018-05-20 00:11:01 -0400240freedoms that you received. You must make sure that they, too, receive
241or can get the source code. And you must show them these terms so they
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400242know their rights.
243
Davide Pesavento1fd00242018-05-20 00:11:01 -0400244Developers that use the GNU GPL protect your rights with two steps:
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400245(1) assert copyright on the software, and (2) offer you this License
246giving you legal permission to copy, distribute and/or modify it.
247
Davide Pesavento1fd00242018-05-20 00:11:01 -0400248For the developers' and authors' protection, the GPL clearly explains
249that there is no warranty for this free software. For both users' and
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400250authors' sake, the GPL requires that modified versions be marked as
251changed, so that their problems will not be attributed erroneously to
252authors of previous versions.
253
Davide Pesavento1fd00242018-05-20 00:11:01 -0400254Some devices are designed to deny users access to install or run
255modified versions of the software inside them, although the
256manufacturer can do so. This is fundamentally incompatible with the
257aim of protecting users' freedom to change the software. The
258systematic pattern of such abuse occurs in the area of products for
259individuals to use, which is precisely where it is most unacceptable.
260Therefore, we have designed this version of the GPL to prohibit the
261practice for those products. If such problems arise substantially in
262other domains, we stand ready to extend this provision to those
263domains in future versions of the GPL, as needed to protect the
264freedom of users.
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400265
Davide Pesavento1fd00242018-05-20 00:11:01 -0400266Finally, every program is threatened constantly by software patents.
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400267States should not allow patents to restrict development and use of
Davide Pesavento1fd00242018-05-20 00:11:01 -0400268software on general-purpose computers, but in those that do, we wish
269to avoid the special danger that patents applied to a free program
270could make it effectively proprietary. To prevent this, the GPL
271assures that patents cannot be used to render the program non-free.
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400272
Davide Pesavento1fd00242018-05-20 00:11:01 -0400273The precise terms and conditions for copying, distribution and
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400274modification follow.

290in a fashion requiring copyright permission, other than the making of
291an exact copy. The resulting work is called a "modified version" of
292the earlier work or a work "based on" the earlier work.
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400293
Davide Pesavento1fd00242018-05-20 00:11:01 -0400294A "covered work" means either the unmodified Program or a work based
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400295on the Program.
296
Davide Pesavento1fd00242018-05-20 00:11:01 -0400297To "propagate" a work means to do anything with it that, without
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400298permission, would make you directly or secondarily liable for
299infringement under applicable copyright law, except executing it on a
Davide Pesavento1fd00242018-05-20 00:11:01 -0400300computer or modifying a private copy. Propagation includes copying,
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400301distribution (with or without modification), making available to the
302public, and in some countries other activities as well.
303
Davide Pesavento1fd00242018-05-20 00:11:01 -0400304To "convey" a work means any kind of propagation that enables other
305parties to make or receive copies. Mere interaction with a user
306through a computer network, with no transfer of a copy, is not
307conveying.
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400308
Davide Pesavento1fd00242018-05-20 00:11:01 -0400309An interactive user interface displays "Appropriate Legal Notices" to
310the extent that it includes a convenient and prominently visible
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400311feature that (1) displays an appropriate copyright notice, and (2)
312tells the user that there is no warranty for the work (except to the
313extent that warranties are provided), that licensees may convey the
Davide Pesavento1fd00242018-05-20 00:11:01 -0400314work under this License, and how to view a copy of this License. If
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400315the interface presents a list of user commands or options, such as a
316menu, a prominent item in the list meets this criterion.
317
Davide Pesavento1fd00242018-05-20 00:11:01 -0400318#### 1. Source Code.
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400319
Davide Pesavento1fd00242018-05-20 00:11:01 -0400320The "source code" for a work means the preferred form of the work for
321making modifications to it. "Object code" means any non-source form of
322a work.
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400323
Davide Pesavento1fd00242018-05-20 00:11:01 -0400324A "Standard Interface" means an interface that either is an official
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400325standard defined by a recognized standards body, or, in the case of
326interfaces specified for a particular programming language, one that
327is widely used among developers working in that language.
328
Davide Pesavento1fd00242018-05-20 00:11:01 -0400329The "System Libraries" of an executable work include anything, other
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400330than the work as a whole, that (a) is included in the normal form of
331packaging a Major Component, but which is not part of that Major
332Component, and (b) serves only to enable use of the work with that
333Major Component, or to implement a Standard Interface for which an
Davide Pesavento1fd00242018-05-20 00:11:01 -0400334implementation is available to the public in source code form. A
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400335"Major Component", in this context, means a major essential component
336(kernel, window system, and so on) of the specific operating system
337(if any) on which the executable work runs, or a compiler used to
338produce the work, or an object code interpreter used to run it.
339
Davide Pesavento1fd00242018-05-20 00:11:01 -0400340The "Corresponding Source" for a work in object code form means all
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400341the source code needed to generate, install, and (for an executable
342work) run the object code and to modify the work, including scripts to
Davide Pesavento1fd00242018-05-20 00:11:01 -0400343control those activities. However, it does not include the work's
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400344System Libraries, or general-purpose tools or generally available free
345programs which are used unmodified in performing those activities but
Davide Pesavento1fd00242018-05-20 00:11:01 -0400346which are not part of the work. For example, Corresponding Source
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400347includes interface definition files associated with source files for
348the work, and the source code for shared libraries and dynamically
349linked subprograms that the work is specifically designed to require,
350such as by intimate data communication or control flow between those
351subprograms and other parts of the work.
352
Davide Pesavento1fd00242018-05-20 00:11:01 -0400353The Corresponding Source need not include anything that users can
354regenerate automatically from other parts of the Corresponding Source.
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400355
Davide Pesavento1fd00242018-05-20 00:11:01 -0400356The Corresponding Source for a work in source code form is that same
357work.
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400358
Davide Pesavento1fd00242018-05-20 00:11:01 -0400359#### 2. Basic Permissions.
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400360
Davide Pesavento1fd00242018-05-20 00:11:01 -0400361All rights granted under this License are granted for the term of
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400362copyright on the Program, and are irrevocable provided the stated
Davide Pesavento1fd00242018-05-20 00:11:01 -0400363conditions are met. This License explicitly affirms your unlimited
364permission to run the unmodified Program. The output from running a
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400365covered work is covered by this License only if the output, given its
Davide Pesavento1fd00242018-05-20 00:11:01 -0400366content, constitutes a covered work. This License acknowledges your
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400367rights of fair use or other equivalent, as provided by copyright law.
368
Davide Pesavento1fd00242018-05-20 00:11:01 -0400369You may make, run and propagate covered works that you do not convey,
370without conditions so long as your license otherwise remains in force.
371You may convey covered works to others for the sole purpose of having
372them make modifications exclusively for you, or provide you with
373facilities for running those works, provided that you comply with the
374terms of this License in conveying all material for which you do not
375control copyright. Those thus making or running the covered works for
376you must do so exclusively on your behalf, under your direction and
377control, on terms that prohibit them from making any copies of your
378copyrighted material outside their relationship with you.
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400379
Davide Pesavento1fd00242018-05-20 00:11:01 -0400380Conveying under any other circumstances is permitted solely under the
381conditions stated below. Sublicensing is not allowed; section 10 makes
382it unnecessary.
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400383
Davide Pesavento1fd00242018-05-20 00:11:01 -0400384#### 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400385
Davide Pesavento1fd00242018-05-20 00:11:01 -0400386No covered work shall be deemed part of an effective technological
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400387measure under any applicable law fulfilling obligations under article
38811 of the WIPO copyright treaty adopted on 20 December 1996, or
389similar laws prohibiting or restricting circumvention of such
390measures.
391
Davide Pesavento1fd00242018-05-20 00:11:01 -0400392When you convey a covered work, you waive any legal power to forbid
393circumvention of technological measures to the extent such
394circumvention is effected by exercising rights under this License with
395respect to the covered work, and you disclaim any intention to limit
396operation or modification of the work as a means of enforcing, against
397the work's users, your or third parties' legal rights to forbid
398circumvention of technological measures.
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400399
Davide Pesavento1fd00242018-05-20 00:11:01 -0400400#### 4. Conveying Verbatim Copies.
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400401
Davide Pesavento1fd00242018-05-20 00:11:01 -0400402You may convey verbatim copies of the Program's source code as you
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400403receive it, in any medium, provided that you conspicuously and
404appropriately publish on each copy an appropriate copyright notice;
405keep intact all notices stating that this License and any
406non-permissive terms added in accord with section 7 apply to the code;
407keep intact all notices of the absence of any warranty; and give all
408recipients a copy of this License along with the Program.
409
Davide Pesavento1fd00242018-05-20 00:11:01 -0400410You may charge any price or no price for each copy that you convey,
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400411and you may offer support or warranty protection for a fee.
412
Davide Pesavento1fd00242018-05-20 00:11:01 -0400413#### 5. Conveying Modified Source Versions.
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400414
Davide Pesavento1fd00242018-05-20 00:11:01 -0400415You may convey a work based on the Program, or the modifications to
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400416produce it from the Program, in the form of source code under the
Davide Pesavento1fd00242018-05-20 00:11:01 -0400417terms of section 4, provided that you also meet all of these
418conditions:
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400419
Davide Pesavento1fd00242018-05-20 00:11:01 -0400420- a) The work must carry prominent notices stating that you modified
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400421 it, and giving a relevant date.
Davide Pesavento1fd00242018-05-20 00:11:01 -0400422- b) The work must carry prominent notices stating that it is
423 released under this License and any conditions added under
424 section 7. This requirement modifies the requirement in section 4
425 to "keep intact all notices".
426- c) You must license the entire work, as a whole, under this
427 License to anyone who comes into possession of a copy. This
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400428 License will therefore apply, along with any applicable section 7
429 additional terms, to the whole of the work, and all its parts,
Davide Pesavento1fd00242018-05-20 00:11:01 -0400430 regardless of how they are packaged. This License gives no
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400431 permission to license the work in any other way, but it does not
432 invalidate such permission if you have separately received it.
Davide Pesavento1fd00242018-05-20 00:11:01 -0400433- d) If the work has interactive user interfaces, each must display
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400434 Appropriate Legal Notices; however, if the Program has interactive
435 interfaces that do not display Appropriate Legal Notices, your
436 work need not make them do so.
437
Davide Pesavento1fd00242018-05-20 00:11:01 -0400438A compilation of a covered work with other separate and independent
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400439works, which are not by their nature extensions of the covered work,
440and which are not combined with it such as to form a larger program,
441in or on a volume of a storage or distribution medium, is called an
442"aggregate" if the compilation and its resulting copyright are not
443used to limit the access or legal rights of the compilation's users
Davide Pesavento1fd00242018-05-20 00:11:01 -0400444beyond what the individual works permit. Inclusion of a covered work
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400445in an aggregate does not cause this License to apply to the other
446parts of the aggregate.
447
Davide Pesavento1fd00242018-05-20 00:11:01 -0400448#### 6. Conveying Non-Source Forms.
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400449
Davide Pesavento1fd00242018-05-20 00:11:01 -0400450You may convey a covered work in object code form under the terms of
451sections 4 and 5, provided that you also convey the machine-readable
452Corresponding Source under the terms of this License, in one of these
453ways:
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400454
Davide Pesavento1fd00242018-05-20 00:11:01 -0400455- a) Convey the object code in, or embodied in, a physical product
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400456 (including a physical distribution medium), accompanied by the
457 Corresponding Source fixed on a durable physical medium
458 customarily used for software interchange.
Davide Pesavento1fd00242018-05-20 00:11:01 -0400459- b) Convey the object code in, or embodied in, a physical product
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400460 (including a physical distribution medium), accompanied by a
461 written offer, valid for at least three years and valid for as
462 long as you offer spare parts or customer support for that product
463 model, to give anyone who possesses the object code either (1) a
464 copy of the Corresponding Source for all the software in the
465 product that is covered by this License, on a durable physical
466 medium customarily used for software interchange, for a price no
467 more than your reasonable cost of physically performing this
Davide Pesavento1fd00242018-05-20 00:11:01 -0400468 conveying of source, or (2) access to copy the Corresponding
469 Source from a network server at no charge.
470- c) Convey individual copies of the object code with a copy of the
471 written offer to provide the Corresponding Source. This
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400472 alternative is allowed only occasionally and noncommercially, and
473 only if you received the object code with such an offer, in accord
474 with subsection 6b.
Davide Pesavento1fd00242018-05-20 00:11:01 -0400475- d) Convey the object code by offering access from a designated
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400476 place (gratis or for a charge), and offer equivalent access to the
477 Corresponding Source in the same way through the same place at no
Davide Pesavento1fd00242018-05-20 00:11:01 -0400478 further charge. You need not require recipients to copy the
479 Corresponding Source along with the object code. If the place to
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400480 copy the object code is a network server, the Corresponding Source
481 may be on a different server (operated by you or a third party)
482 that supports equivalent copying facilities, provided you maintain
483 clear directions next to the object code saying where to find the
Davide Pesavento1fd00242018-05-20 00:11:01 -0400484 Corresponding Source. Regardless of what server hosts the
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400485 Corresponding Source, you remain obligated to ensure that it is
486 available for as long as needed to satisfy these requirements.
Davide Pesavento1fd00242018-05-20 00:11:01 -0400487- e) Convey the object code using peer-to-peer transmission,
488 provided you inform other peers where the object code and
489 Corresponding Source of the work are being offered to the general
490 public at no charge under subsection 6d.
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400491
Davide Pesavento1fd00242018-05-20 00:11:01 -0400492A separable portion of the object code, whose source code is excluded
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400493from the Corresponding Source as a System Library, need not be
494included in conveying the object code work.
495
Davide Pesavento1fd00242018-05-20 00:11:01 -0400496A "User Product" is either (1) a "consumer product", which means any
497tangible personal property which is normally used for personal,
498family, or household purposes, or (2) anything designed or sold for
499incorporation into a dwelling. In determining whether a product is a
500consumer product, doubtful cases shall be resolved in favor of
501coverage. For a particular product received by a particular user,
502"normally used" refers to a typical or common use of that class of
503product, regardless of the status of the particular user or of the way
504in which the particular user actually uses, or expects or is expected
505to use, the product. A product is a consumer product regardless of
506whether the product has substantial commercial, industrial or
507non-consumer uses, unless such uses represent the only significant
508mode of use of the product.
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400509
Davide Pesavento1fd00242018-05-20 00:11:01 -0400510"Installation Information" for a User Product means any methods,
511procedures, authorization keys, or other information required to
512install and execute modified versions of a covered work in that User
513Product from a modified version of its Corresponding Source. The
514information must suffice to ensure that the continued functioning of
515the modified object code is in no case prevented or interfered with
516solely because modification has been made.
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400517
Davide Pesavento1fd00242018-05-20 00:11:01 -0400518If you convey an object code work under this section in, or with, or
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400519specifically for use in, a User Product, and the conveying occurs as
520part of a transaction in which the right of possession and use of the
521User Product is transferred to the recipient in perpetuity or for a
522fixed term (regardless of how the transaction is characterized), the
523Corresponding Source conveyed under this section must be accompanied
Davide Pesavento1fd00242018-05-20 00:11:01 -0400524by the Installation Information. But this requirement does not apply
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400525if neither you nor any third party retains the ability to install
526modified object code on the User Product (for example, the work has
527been installed in ROM).
528
Davide Pesavento1fd00242018-05-20 00:11:01 -0400529The requirement to provide Installation Information does not include a
530requirement to continue to provide support service, warranty, or
531updates for a work that has been modified or installed by the
532recipient, or for the User Product in which it has been modified or
533installed. Access to a network may be denied when the modification
534itself materially and adversely affects the operation of the network
535or violates the rules and protocols for communication across the
536network.
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400537
Davide Pesavento1fd00242018-05-20 00:11:01 -0400538Corresponding Source conveyed, and Installation Information provided,
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400539in accord with this section must be in a format that is publicly
540documented (and with an implementation available to the public in
541source code form), and must require no special password or key for
542unpacking, reading or copying.
543
Davide Pesavento1fd00242018-05-20 00:11:01 -0400544#### 7. Additional Terms.
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400545
Davide Pesavento1fd00242018-05-20 00:11:01 -0400546"Additional permissions" are terms that supplement the terms of this
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400547License by making exceptions from one or more of its conditions.
548Additional permissions that are applicable to the entire Program shall
549be treated as though they were included in this License, to the extent
Davide Pesavento1fd00242018-05-20 00:11:01 -0400550that they are valid under applicable law. If additional permissions
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400551apply only to part of the Program, that part may be used separately
552under those permissions, but the entire Program remains governed by
553this License without regard to the additional permissions.
554
Davide Pesavento1fd00242018-05-20 00:11:01 -0400555When you convey a copy of a covered work, you may at your option
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400556remove any additional permissions from that copy, or from any part of
Davide Pesavento1fd00242018-05-20 00:11:01 -0400557it. (Additional permissions may be written to require their own
558removal in certain cases when you modify the work.) You may place
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400559additional permissions on material, added by you to a covered work,
560for which you have or can give appropriate copyright permission.
561
Davide Pesavento1fd00242018-05-20 00:11:01 -0400562Notwithstanding any other provision of this License, for material you
563add to a covered work, you may (if authorized by the copyright holders
564of that material) supplement the terms of this License with terms:
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400565
Davide Pesavento1fd00242018-05-20 00:11:01 -0400566- a) Disclaiming warranty or limiting liability differently from the
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400567 terms of sections 15 and 16 of this License; or
Davide Pesavento1fd00242018-05-20 00:11:01 -0400568- b) Requiring preservation of specified reasonable legal notices or
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400569 author attributions in that material or in the Appropriate Legal
570 Notices displayed by works containing it; or
Davide Pesavento1fd00242018-05-20 00:11:01 -0400571- c) Prohibiting misrepresentation of the origin of that material,
572 or requiring that modified versions of such material be marked in
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400573 reasonable ways as different from the original version; or
Davide Pesavento1fd00242018-05-20 00:11:01 -0400574- d) Limiting the use for publicity purposes of names of licensors
575 or authors of the material; or
576- e) Declining to grant rights under trademark law for use of some
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400577 trade names, trademarks, or service marks; or
Davide Pesavento1fd00242018-05-20 00:11:01 -0400578- f) Requiring indemnification of licensors and authors of that
579 material by anyone who conveys the material (or modified versions
580 of it) with contractual assumptions of liability to the recipient,
581 for any liability that these contractual assumptions directly
582 impose on those licensors and authors.
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400583
Davide Pesavento1fd00242018-05-20 00:11:01 -0400584All other non-permissive additional terms are considered "further
585restrictions" within the meaning of section 10. If the Program as you
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400586received it, or any part of it, contains a notice stating that it is
587governed by this License along with a term that is a further
Davide Pesavento1fd00242018-05-20 00:11:01 -0400588restriction, you may remove that term. If a license document contains
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400589a further restriction but permits relicensing or conveying under this
590License, you may add to a covered work material governed by the terms
591of that license document, provided that the further restriction does
592not survive such relicensing or conveying.
593
Davide Pesavento1fd00242018-05-20 00:11:01 -0400594If you add terms to a covered work in accord with this section, you
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400595must place, in the relevant source files, a statement of the
596additional terms that apply to those files, or a notice indicating
597where to find the applicable terms.
598
Davide Pesavento1fd00242018-05-20 00:11:01 -0400599Additional terms, permissive or non-permissive, may be stated in the
600form of a separately written license, or stated as exceptions; the
601above requirements apply either way.
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400602
Davide Pesavento1fd00242018-05-20 00:11:01 -0400603#### 8. Termination.
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400604
Davide Pesavento1fd00242018-05-20 00:11:01 -0400605You may not propagate or modify a covered work except as expressly
606provided under this License. Any attempt otherwise to propagate or
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400607modify it is void, and will automatically terminate your rights under
608this License (including any patent licenses granted under the third
609paragraph of section 11).
610
Davide Pesavento1fd00242018-05-20 00:11:01 -0400611However, if you cease all violation of this License, then your license
612from a particular copyright holder is reinstated (a) provisionally,
613unless and until the copyright holder explicitly and finally
614terminates your license, and (b) permanently, if the copyright holder
615fails to notify you of the violation by some reasonable means prior to
61660 days after the cessation.
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400617
Davide Pesavento1fd00242018-05-20 00:11:01 -0400618Moreover, your license from a particular copyright holder is
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400619reinstated permanently if the copyright holder notifies you of the
620violation by some reasonable means, this is the first time you have
621received notice of violation of this License (for any work) from that
622copyright holder, and you cure the violation prior to 30 days after
623your receipt of the notice.
624
Davide Pesavento1fd00242018-05-20 00:11:01 -0400625Termination of your rights under this section does not terminate the
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400626licenses of parties who have received copies or rights from you under
Davide Pesavento1fd00242018-05-20 00:11:01 -0400627this License. If your rights have been terminated and not permanently
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400628reinstated, you do not qualify to receive new licenses for the same
629material under section 10.
630
Davide Pesavento1fd00242018-05-20 00:11:01 -0400631#### 9. Acceptance Not Required for Having Copies.
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400632
Davide Pesavento1fd00242018-05-20 00:11:01 -0400633You are not required to accept this License in order to receive or run
634a copy of the Program. Ancillary propagation of a covered work
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400635occurring solely as a consequence of using peer-to-peer transmission
Davide Pesavento1fd00242018-05-20 00:11:01 -0400636to receive a copy likewise does not require acceptance. However,
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400637nothing other than this License grants you permission to propagate or
Davide Pesavento1fd00242018-05-20 00:11:01 -0400638modify any covered work. These actions infringe copyright if you do
639not accept this License. Therefore, by modifying or propagating a
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400640covered work, you indicate your acceptance of this License to do so.
641
Davide Pesavento1fd00242018-05-20 00:11:01 -0400642#### 10. Automatic Licensing of Downstream Recipients.
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400643
Davide Pesavento1fd00242018-05-20 00:11:01 -0400644Each time you convey a covered work, the recipient automatically
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400645receives a license from the original licensors, to run, modify and
Davide Pesavento1fd00242018-05-20 00:11:01 -0400646propagate that work, subject to this License. You are not responsible
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400647for enforcing compliance by third parties with this License.
648
Davide Pesavento1fd00242018-05-20 00:11:01 -0400649An "entity transaction" is a transaction transferring control of an
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400650organization, or substantially all assets of one, or subdividing an
Davide Pesavento1fd00242018-05-20 00:11:01 -0400651organization, or merging organizations. If propagation of a covered
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400652work results from an entity transaction, each party to that
653transaction who receives a copy of the work also receives whatever
654licenses to the work the party's predecessor in interest had or could
655give under the previous paragraph, plus a right to possession of the
656Corresponding Source of the work from the predecessor in interest, if
657the predecessor has it or can get it with reasonable efforts.
658
Davide Pesavento1fd00242018-05-20 00:11:01 -0400659You may not impose any further restrictions on the exercise of the
660rights granted or affirmed under this License. For example, you may
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400661not impose a license fee, royalty, or other charge for exercise of
662rights granted under this License, and you may not initiate litigation
663(including a cross-claim or counterclaim in a lawsuit) alleging that
664any patent claim is infringed by making, using, selling, offering for
665sale, or importing the Program or any portion of it.
666
Davide Pesavento1fd00242018-05-20 00:11:01 -0400667#### 11. Patents.
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400668
Davide Pesavento1fd00242018-05-20 00:11:01 -0400669A "contributor" is a copyright holder who authorizes use under this
670License of the Program or a work on which the Program is based. The
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400671work thus licensed is called the contributor's "contributor version".
672
Davide Pesavento1fd00242018-05-20 00:11:01 -0400673A contributor's "essential patent claims" are all patent claims owned
674or controlled by the contributor, whether already acquired or
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400675hereafter acquired, that would be infringed by some manner, permitted
676by this License, of making, using, or selling its contributor version,
677but do not include claims that would be infringed only as a
Davide Pesavento1fd00242018-05-20 00:11:01 -0400678consequence of further modification of the contributor version. For
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400679purposes of this definition, "control" includes the right to grant
680patent sublicenses in a manner consistent with the requirements of
681this License.
682
Davide Pesavento1fd00242018-05-20 00:11:01 -0400683Each contributor grants you a non-exclusive, worldwide, royalty-free
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400684patent license under the contributor's essential patent claims, to
685make, use, sell, offer for sale, import and otherwise run, modify and
686propagate the contents of its contributor version.
687
Davide Pesavento1fd00242018-05-20 00:11:01 -0400688In the following three paragraphs, a "patent license" is any express
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400689agreement or commitment, however denominated, not to enforce a patent
690(such as an express permission to practice a patent or covenant not to
Davide Pesavento1fd00242018-05-20 00:11:01 -0400691sue for patent infringement). To "grant" such a patent license to a
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400692party means to make such an agreement or commitment not to enforce a
693patent against the party.
694
Davide Pesavento1fd00242018-05-20 00:11:01 -0400695If you convey a covered work, knowingly relying on a patent license,
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400696and the Corresponding Source of the work is not available for anyone
697to copy, free of charge and under the terms of this License, through a
698publicly available network server or other readily accessible means,
699then you must either (1) cause the Corresponding Source to be so
700available, or (2) arrange to deprive yourself of the benefit of the
701patent license for this particular work, or (3) arrange, in a manner
702consistent with the requirements of this License, to extend the patent
Davide Pesavento1fd00242018-05-20 00:11:01 -0400703license to downstream recipients. "Knowingly relying" means you have
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400704actual knowledge that, but for the patent license, your conveying the
705covered work in a country, or your recipient's use of the covered work
706in a country, would infringe one or more identifiable patents in that
707country that you have reason to believe are valid.
708
Davide Pesavento1fd00242018-05-20 00:11:01 -0400709If, pursuant to or in connection with a single transaction or
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400710arrangement, you convey, or propagate by procuring conveyance of, a
711covered work, and grant a patent license to some of the parties
712receiving the covered work authorizing them to use, propagate, modify
713or convey a specific copy of the covered work, then the patent license
714you grant is automatically extended to all recipients of the covered
715work and works based on it.
716
Davide Pesavento1fd00242018-05-20 00:11:01 -0400717A patent license is "discriminatory" if it does not include within the
718scope of its coverage, prohibits the exercise of, or is conditioned on
719the non-exercise of one or more of the rights that are specifically
720granted under this License. You may not convey a covered work if you
721are a party to an arrangement with a third party that is in the
722business of distributing software, under which you make payment to the
723third party based on the extent of your activity of conveying the
724work, and under which the third party grants, to any of the parties
725who would receive the covered work from you, a discriminatory patent
726license (a) in connection with copies of the covered work conveyed by
727you (or copies made from those copies), or (b) primarily for and in
728connection with specific products or compilations that contain the
729covered work, unless you entered into that arrangement, or that patent
730license was granted, prior to 28 March 2007.
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400731
Davide Pesavento1fd00242018-05-20 00:11:01 -0400732Nothing in this License shall be construed as excluding or limiting
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400733any implied license or other defenses to infringement that may
734otherwise be available to you under applicable patent law.
735
Davide Pesavento1fd00242018-05-20 00:11:01 -0400736#### 12. No Surrender of Others' Freedom.
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400737
Davide Pesavento1fd00242018-05-20 00:11:01 -0400738If conditions are imposed on you (whether by court order, agreement or
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400739otherwise) that contradict the conditions of this License, they do not
Davide Pesavento1fd00242018-05-20 00:11:01 -0400740excuse you from the conditions of this License. If you cannot convey a
741covered work so as to satisfy simultaneously your obligations under
742this License and any other pertinent obligations, then as a
743consequence you may not convey it at all. For example, if you agree to
744terms that obligate you to collect a royalty for further conveying
745from those to whom you convey the Program, the only way you could
746satisfy both those terms and this License would be to refrain entirely
747from conveying the Program.
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400748
Davide Pesavento1fd00242018-05-20 00:11:01 -0400749#### 13. Use with the GNU Affero General Public License.
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400750
Davide Pesavento1fd00242018-05-20 00:11:01 -0400751Notwithstanding any other provision of this License, you have
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400752permission to link or combine any covered work with a work licensed
753under version 3 of the GNU Affero General Public License into a single
Davide Pesavento1fd00242018-05-20 00:11:01 -0400754combined work, and to convey the resulting work. The terms of this
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400755License will continue to apply to the part which is the covered work,
756but the special requirements of the GNU Affero General Public License,
757section 13, concerning interaction through a network will apply to the
758combination as such.
759
Davide Pesavento1fd00242018-05-20 00:11:01 -0400760#### 14. Revised Versions of this License.
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400761
Davide Pesavento1fd00242018-05-20 00:11:01 -0400762The Free Software Foundation may publish revised and/or new versions
763of the GNU General Public License from time to time. Such new versions
764will be similar in spirit to the present version, but may differ in
765detail to address new problems or concerns.
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400766
Davide Pesavento1fd00242018-05-20 00:11:01 -0400767Each version is given a distinguishing version number. If the Program
768specifies that a certain numbered version of the GNU General Public
769License "or any later version" applies to it, you have the option of
770following the terms and conditions either of that numbered version or
771of any later version published by the Free Software Foundation. If the
772Program does not specify a version number of the GNU General Public
773License, you may choose any version ever published by the Free
774Software Foundation.
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400775
Davide Pesavento1fd00242018-05-20 00:11:01 -0400776If the Program specifies that a proxy can decide which future versions
777of the GNU General Public License can be used, that proxy's public
778statement of acceptance of a version permanently authorizes you to
779choose that version for the Program.
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400780
Davide Pesavento1fd00242018-05-20 00:11:01 -0400781Later license versions may give you additional or different
782permissions. However, no additional obligations are imposed on any
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400783author or copyright holder as a result of your choosing to follow a
784later version.
785
Davide Pesavento1fd00242018-05-20 00:11:01 -0400786#### 15. Disclaimer of Warranty.
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400787
Davide Pesavento1fd00242018-05-20 00:11:01 -0400788THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
789APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
790HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT
791WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT
792LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR
793A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND
794PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE
795DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
796CORRECTION.
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400797
Davide Pesavento1fd00242018-05-20 00:11:01 -0400798#### 16. Limitation of Liability.
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400799
Davide Pesavento1fd00242018-05-20 00:11:01 -0400800IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
801WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR
802CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
803INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES
804ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT
805NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR
806LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM
807TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER
808PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400809
Davide Pesavento1fd00242018-05-20 00:11:01 -0400810#### 17. Interpretation of Sections 15 and 16.
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400811
Davide Pesavento1fd00242018-05-20 00:11:01 -0400812If the disclaimer of warranty and limitation of liability provided
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400813above cannot be given local legal effect according to their terms,
814reviewing courts shall apply local law that most closely approximates
815an absolute waiver of all civil liability in connection with the
816Program, unless a warranty or assumption of liability accompanies a
817copy of the Program in return for a fee.

Davide Pesavento1fd00242018-05-20 00:11:01 -0400821### How to Apply These Terms to Your New Programs
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400822
Davide Pesavento1fd00242018-05-20 00:11:01 -0400823If you develop a new program, and you want it to be of the greatest
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400824possible use to the public, the best way to achieve this is to make it
Davide Pesavento1fd00242018-05-20 00:11:01 -0400825free software which everyone can redistribute and change under these
826terms.
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400827
Davide Pesavento1fd00242018-05-20 00:11:01 -0400828To do so, attach the following notices to the program. It is safest to
829attach them to the start of each source file to most effectively state
830the exclusion of warranty; and each file should have at least the
831"copyright" line and a pointer to where the full notice is found.

Davide Pesavento1fd00242018-05-20 00:11:01 -0400846 You should have received a copy of the GNU General Public License

Davide Pesavento1fd00242018-05-20 00:11:01 -0400849Also add information on how to contact you by electronic and paper
850mail.
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400851
Davide Pesavento1fd00242018-05-20 00:11:01 -0400852If the program does terminal interaction, make it output a short
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400853notice like this when it starts in an interactive mode:
854

856 This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
857 This is free software, and you are welcome to redistribute it
858 under certain conditions; type `show c' for details.
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400859
Davide Pesavento1fd00242018-05-20 00:11:01 -0400860The hypothetical commands \`show w' and \`show c' should show the
861appropriate parts of the General Public License. Of course, your
862program's commands might be different; for a GUI interface, you would
863use an "about box".
Alexander Afanasyevc169a812014-05-20 20:37:29 -0400864
Davide Pesavento1fd00242018-05-20 00:11:01 -0400865You should also get your employer (if you work as a programmer) or
866school, if any, to sign a "copyright disclaimer" for the program, if
867necessary. For more information on this, and how to apply and follow
868the GNU GPL, see <https://www.gnu.org/licenses/>.

Davide Pesavento1fd00242018-05-20 00:11:01 -0400870The GNU General Public License does not permit incorporating your
871program into proprietary programs. If your program is a subroutine
872library, you may consider it more useful to permit linking proprietary
873applications with the library. If this is what you want to do, use the
874GNU Lesser General Public License instead of this License. But first,
875please read <https://www.gnu.org/licenses/why-not-lgpl.html>.
