5 406d7b4d 2020-12-26 op Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
6 406d7b4d 2020-12-26 op Everyone is permitted to copy and distribute verbatim copies
7 406d7b4d 2020-12-26 op of this license document, but changing it is not allowed.
11 406d7b4d 2020-12-26 op The GNU General Public License is a free, copyleft license for
12 406d7b4d 2020-12-26 op software and other kinds of works.
14 406d7b4d 2020-12-26 op The licenses for most software and other practical works are designed
15 406d7b4d 2020-12-26 op to take away your freedom to share and change the works. By contrast,
16 406d7b4d 2020-12-26 op the GNU General Public License is intended to guarantee your freedom to
17 406d7b4d 2020-12-26 op share and change all versions of a program--to make sure it remains free
18 406d7b4d 2020-12-26 op software for all its users. We, the Free Software Foundation, use the
19 406d7b4d 2020-12-26 op GNU General Public License for most of our software; it applies also to
20 406d7b4d 2020-12-26 op any other work released this way by its authors. You can apply it to
21 406d7b4d 2020-12-26 op your programs, too.
23 406d7b4d 2020-12-26 op When we speak of free software, we are referring to freedom, not
24 406d7b4d 2020-12-26 op price. Our General Public Licenses are designed to make sure that you
25 406d7b4d 2020-12-26 op have the freedom to distribute copies of free software (and charge for
26 406d7b4d 2020-12-26 op them if you wish), that you receive source code or can get it if you
27 406d7b4d 2020-12-26 op want it, that you can change the software or use pieces of it in new
28 406d7b4d 2020-12-26 op free programs, and that you know you can do these things.
30 406d7b4d 2020-12-26 op To protect your rights, we need to prevent others from denying you
31 406d7b4d 2020-12-26 op these rights or asking you to surrender the rights. Therefore, you have
32 406d7b4d 2020-12-26 op certain responsibilities if you distribute copies of the software, or if
33 406d7b4d 2020-12-26 op you modify it: responsibilities to respect the freedom of others.
35 406d7b4d 2020-12-26 op For example, if you distribute copies of such a program, whether
36 406d7b4d 2020-12-26 op gratis or for a fee, you must pass on to the recipients the same
37 406d7b4d 2020-12-26 op freedoms that you received. You must make sure that they, too, receive
38 406d7b4d 2020-12-26 op or can get the source code. And you must show them these terms so they
39 406d7b4d 2020-12-26 op know their rights.
41 406d7b4d 2020-12-26 op Developers that use the GNU GPL protect your rights with two steps:
42 406d7b4d 2020-12-26 op (1) assert copyright on the software, and (2) offer you this License
43 406d7b4d 2020-12-26 op giving you legal permission to copy, distribute and/or modify it.
45 406d7b4d 2020-12-26 op For the developers' and authors' protection, the GPL clearly explains
46 406d7b4d 2020-12-26 op that there is no warranty for this free software. For both users' and
47 406d7b4d 2020-12-26 op authors' sake, the GPL requires that modified versions be marked as
48 406d7b4d 2020-12-26 op changed, so that their problems will not be attributed erroneously to
49 406d7b4d 2020-12-26 op authors of previous versions.
51 406d7b4d 2020-12-26 op Some devices are designed to deny users access to install or run
52 406d7b4d 2020-12-26 op modified versions of the software inside them, although the manufacturer
53 406d7b4d 2020-12-26 op can do so. This is fundamentally incompatible with the aim of
54 406d7b4d 2020-12-26 op protecting users' freedom to change the software. The systematic
55 406d7b4d 2020-12-26 op pattern of such abuse occurs in the area of products for individuals to
56 406d7b4d 2020-12-26 op use, which is precisely where it is most unacceptable. Therefore, we
57 406d7b4d 2020-12-26 op have designed this version of the GPL to prohibit the practice for those
58 406d7b4d 2020-12-26 op products. If such problems arise substantially in other domains, we
59 406d7b4d 2020-12-26 op stand ready to extend this provision to those domains in future versions
60 406d7b4d 2020-12-26 op of the GPL, as needed to protect the freedom of users.
62 406d7b4d 2020-12-26 op Finally, every program is threatened constantly by software patents.
63 406d7b4d 2020-12-26 op States should not allow patents to restrict development and use of
64 406d7b4d 2020-12-26 op software on general-purpose computers, but in those that do, we wish to
65 406d7b4d 2020-12-26 op avoid the special danger that patents applied to a free program could
66 406d7b4d 2020-12-26 op make it effectively proprietary. To prevent this, the GPL assures that
67 406d7b4d 2020-12-26 op patents cannot be used to render the program non-free.
69 406d7b4d 2020-12-26 op The precise terms and conditions for copying, distribution and
70 406d7b4d 2020-12-26 op modification follow.
72 406d7b4d 2020-12-26 op TERMS AND CONDITIONS
74 406d7b4d 2020-12-26 op 0. Definitions.
76 406d7b4d 2020-12-26 op "This License" refers to version 3 of the GNU General Public License.
78 406d7b4d 2020-12-26 op "Copyright" also means copyright-like laws that apply to other kinds of
79 406d7b4d 2020-12-26 op works, such as semiconductor masks.
81 406d7b4d 2020-12-26 op "The Program" refers to any copyrightable work licensed under this
82 406d7b4d 2020-12-26 op License. Each licensee is addressed as "you". "Licensees" and
83 406d7b4d 2020-12-26 op "recipients" may be individuals or organizations.
85 406d7b4d 2020-12-26 op To "modify" a work means to copy from or adapt all or part of the work
86 406d7b4d 2020-12-26 op in a fashion requiring copyright permission, other than the making of an
87 406d7b4d 2020-12-26 op exact copy. The resulting work is called a "modified version" of the
88 406d7b4d 2020-12-26 op earlier work or a work "based on" the earlier work.
90 406d7b4d 2020-12-26 op A "covered work" means either the unmodified Program or a work based
91 406d7b4d 2020-12-26 op on the Program.
93 406d7b4d 2020-12-26 op To "propagate" a work means to do anything with it that, without
94 406d7b4d 2020-12-26 op permission, would make you directly or secondarily liable for
95 406d7b4d 2020-12-26 op infringement under applicable copyright law, except executing it on a
96 406d7b4d 2020-12-26 op computer or modifying a private copy. Propagation includes copying,
97 406d7b4d 2020-12-26 op distribution (with or without modification), making available to the
98 406d7b4d 2020-12-26 op public, and in some countries other activities as well.
100 406d7b4d 2020-12-26 op To "convey" a work means any kind of propagation that enables other
101 406d7b4d 2020-12-26 op parties to make or receive copies. Mere interaction with a user through
102 406d7b4d 2020-12-26 op a computer network, with no transfer of a copy, is not conveying.
104 406d7b4d 2020-12-26 op An interactive user interface displays "Appropriate Legal Notices"
105 406d7b4d 2020-12-26 op to the extent that it includes a convenient and prominently visible
106 406d7b4d 2020-12-26 op feature that (1) displays an appropriate copyright notice, and (2)
107 406d7b4d 2020-12-26 op tells the user that there is no warranty for the work (except to the
108 406d7b4d 2020-12-26 op extent that warranties are provided), that licensees may convey the
109 406d7b4d 2020-12-26 op work under this License, and how to view a copy of this License. If
110 406d7b4d 2020-12-26 op the interface presents a list of user commands or options, such as a
111 406d7b4d 2020-12-26 op menu, a prominent item in the list meets this criterion.
113 406d7b4d 2020-12-26 op 1. Source Code.
115 406d7b4d 2020-12-26 op The "source code" for a work means the preferred form of the work
116 406d7b4d 2020-12-26 op for making modifications to it. "Object code" means any non-source
117 406d7b4d 2020-12-26 op form of a work.
119 406d7b4d 2020-12-26 op A "Standard Interface" means an interface that either is an official
120 406d7b4d 2020-12-26 op standard defined by a recognized standards body, or, in the case of
121 406d7b4d 2020-12-26 op interfaces specified for a particular programming language, one that
122 406d7b4d 2020-12-26 op is widely used among developers working in that language.
124 406d7b4d 2020-12-26 op The "System Libraries" of an executable work include anything, other
125 406d7b4d 2020-12-26 op than the work as a whole, that (a) is included in the normal form of
126 406d7b4d 2020-12-26 op packaging a Major Component, but which is not part of that Major
127 406d7b4d 2020-12-26 op Component, and (b) serves only to enable use of the work with that
128 406d7b4d 2020-12-26 op Major Component, or to implement a Standard Interface for which an
129 406d7b4d 2020-12-26 op implementation is available to the public in source code form. A
130 406d7b4d 2020-12-26 op "Major Component", in this context, means a major essential component
131 406d7b4d 2020-12-26 op (kernel, window system, and so on) of the specific operating system
132 406d7b4d 2020-12-26 op (if any) on which the executable work runs, or a compiler used to
133 406d7b4d 2020-12-26 op produce the work, or an object code interpreter used to run it.
135 406d7b4d 2020-12-26 op The "Corresponding Source" for a work in object code form means all
136 406d7b4d 2020-12-26 op the source code needed to generate, install, and (for an executable
137 406d7b4d 2020-12-26 op work) run the object code and to modify the work, including scripts to
138 406d7b4d 2020-12-26 op control those activities. However, it does not include the work's
139 406d7b4d 2020-12-26 op System Libraries, or general-purpose tools or generally available free
140 406d7b4d 2020-12-26 op programs which are used unmodified in performing those activities but
141 406d7b4d 2020-12-26 op which are not part of the work. For example, Corresponding Source
142 406d7b4d 2020-12-26 op includes interface definition files associated with source files for
143 406d7b4d 2020-12-26 op the work, and the source code for shared libraries and dynamically
144 406d7b4d 2020-12-26 op linked subprograms that the work is specifically designed to require,
145 406d7b4d 2020-12-26 op such as by intimate data communication or control flow between those
146 406d7b4d 2020-12-26 op subprograms and other parts of the work.
148 406d7b4d 2020-12-26 op The Corresponding Source need not include anything that users
149 406d7b4d 2020-12-26 op can regenerate automatically from other parts of the Corresponding
152 406d7b4d 2020-12-26 op The Corresponding Source for a work in source code form is that
155 406d7b4d 2020-12-26 op 2. Basic Permissions.
157 406d7b4d 2020-12-26 op All rights granted under this License are granted for the term of
158 406d7b4d 2020-12-26 op copyright on the Program, and are irrevocable provided the stated
159 406d7b4d 2020-12-26 op conditions are met. This License explicitly affirms your unlimited
160 406d7b4d 2020-12-26 op permission to run the unmodified Program. The output from running a
161 406d7b4d 2020-12-26 op covered work is covered by this License only if the output, given its
162 406d7b4d 2020-12-26 op content, constitutes a covered work. This License acknowledges your
163 406d7b4d 2020-12-26 op rights of fair use or other equivalent, as provided by copyright law.
165 406d7b4d 2020-12-26 op You may make, run and propagate covered works that you do not
166 406d7b4d 2020-12-26 op convey, without conditions so long as your license otherwise remains
167 406d7b4d 2020-12-26 op in force. You may convey covered works to others for the sole purpose
168 406d7b4d 2020-12-26 op of having them make modifications exclusively for you, or provide you
169 406d7b4d 2020-12-26 op with facilities for running those works, provided that you comply with
170 406d7b4d 2020-12-26 op the terms of this License in conveying all material for which you do
171 406d7b4d 2020-12-26 op not control copyright. Those thus making or running the covered works
172 406d7b4d 2020-12-26 op for you must do so exclusively on your behalf, under your direction
173 406d7b4d 2020-12-26 op and control, on terms that prohibit them from making any copies of
174 406d7b4d 2020-12-26 op your copyrighted material outside their relationship with you.
176 406d7b4d 2020-12-26 op Conveying under any other circumstances is permitted solely under
177 406d7b4d 2020-12-26 op the conditions stated below. Sublicensing is not allowed; section 10
178 406d7b4d 2020-12-26 op makes it unnecessary.
180 406d7b4d 2020-12-26 op 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
182 406d7b4d 2020-12-26 op No covered work shall be deemed part of an effective technological
183 406d7b4d 2020-12-26 op measure under any applicable law fulfilling obligations under article
184 406d7b4d 2020-12-26 op 11 of the WIPO copyright treaty adopted on 20 December 1996, or
185 406d7b4d 2020-12-26 op similar laws prohibiting or restricting circumvention of such
188 406d7b4d 2020-12-26 op When you convey a covered work, you waive any legal power to forbid
189 406d7b4d 2020-12-26 op circumvention of technological measures to the extent such circumvention
190 406d7b4d 2020-12-26 op is effected by exercising rights under this License with respect to
191 406d7b4d 2020-12-26 op the covered work, and you disclaim any intention to limit operation or
192 406d7b4d 2020-12-26 op modification of the work as a means of enforcing, against the work's
193 406d7b4d 2020-12-26 op users, your or third parties' legal rights to forbid circumvention of
194 406d7b4d 2020-12-26 op technological measures.
196 406d7b4d 2020-12-26 op 4. Conveying Verbatim Copies.
198 406d7b4d 2020-12-26 op You may convey verbatim copies of the Program's source code as you
199 406d7b4d 2020-12-26 op receive it, in any medium, provided that you conspicuously and
200 406d7b4d 2020-12-26 op appropriately publish on each copy an appropriate copyright notice;
201 406d7b4d 2020-12-26 op keep intact all notices stating that this License and any
202 406d7b4d 2020-12-26 op non-permissive terms added in accord with section 7 apply to the code;
203 406d7b4d 2020-12-26 op keep intact all notices of the absence of any warranty; and give all
204 406d7b4d 2020-12-26 op recipients a copy of this License along with the Program.
206 406d7b4d 2020-12-26 op You may charge any price or no price for each copy that you convey,
207 406d7b4d 2020-12-26 op and you may offer support or warranty protection for a fee.
209 406d7b4d 2020-12-26 op 5. Conveying Modified Source Versions.
211 406d7b4d 2020-12-26 op You may convey a work based on the Program, or the modifications to
212 406d7b4d 2020-12-26 op produce it from the Program, in the form of source code under the
213 406d7b4d 2020-12-26 op terms of section 4, provided that you also meet all of these conditions:
215 406d7b4d 2020-12-26 op a) The work must carry prominent notices stating that you modified
216 406d7b4d 2020-12-26 op it, and giving a relevant date.
218 406d7b4d 2020-12-26 op b) The work must carry prominent notices stating that it is
219 406d7b4d 2020-12-26 op released under this License and any conditions added under section
220 406d7b4d 2020-12-26 op 7. This requirement modifies the requirement in section 4 to
221 406d7b4d 2020-12-26 op "keep intact all notices".
223 406d7b4d 2020-12-26 op c) You must license the entire work, as a whole, under this
224 406d7b4d 2020-12-26 op License to anyone who comes into possession of a copy. This
225 406d7b4d 2020-12-26 op License will therefore apply, along with any applicable section 7
226 406d7b4d 2020-12-26 op additional terms, to the whole of the work, and all its parts,
227 406d7b4d 2020-12-26 op regardless of how they are packaged. This License gives no
228 406d7b4d 2020-12-26 op permission to license the work in any other way, but it does not
229 406d7b4d 2020-12-26 op invalidate such permission if you have separately received it.
231 406d7b4d 2020-12-26 op d) If the work has interactive user interfaces, each must display
232 406d7b4d 2020-12-26 op Appropriate Legal Notices; however, if the Program has interactive
233 406d7b4d 2020-12-26 op interfaces that do not display Appropriate Legal Notices, your
234 406d7b4d 2020-12-26 op work need not make them do so.
236 406d7b4d 2020-12-26 op A compilation of a covered work with other separate and independent
237 406d7b4d 2020-12-26 op works, which are not by their nature extensions of the covered work,
238 406d7b4d 2020-12-26 op and which are not combined with it such as to form a larger program,
239 406d7b4d 2020-12-26 op in or on a volume of a storage or distribution medium, is called an
240 406d7b4d 2020-12-26 op "aggregate" if the compilation and its resulting copyright are not
241 406d7b4d 2020-12-26 op used to limit the access or legal rights of the compilation's users
242 406d7b4d 2020-12-26 op beyond what the individual works permit. Inclusion of a covered work
243 406d7b4d 2020-12-26 op in an aggregate does not cause this License to apply to the other
244 406d7b4d 2020-12-26 op parts of the aggregate.
246 406d7b4d 2020-12-26 op 6. Conveying Non-Source Forms.
248 406d7b4d 2020-12-26 op You may convey a covered work in object code form under the terms
249 406d7b4d 2020-12-26 op of sections 4 and 5, provided that you also convey the
250 406d7b4d 2020-12-26 op machine-readable Corresponding Source under the terms of this License,
251 406d7b4d 2020-12-26 op in one of these ways:
253 406d7b4d 2020-12-26 op a) Convey the object code in, or embodied in, a physical product
254 406d7b4d 2020-12-26 op (including a physical distribution medium), accompanied by the
255 406d7b4d 2020-12-26 op Corresponding Source fixed on a durable physical medium
256 406d7b4d 2020-12-26 op customarily used for software interchange.
258 406d7b4d 2020-12-26 op b) Convey the object code in, or embodied in, a physical product
259 406d7b4d 2020-12-26 op (including a physical distribution medium), accompanied by a
260 406d7b4d 2020-12-26 op written offer, valid for at least three years and valid for as
261 406d7b4d 2020-12-26 op long as you offer spare parts or customer support for that product
262 406d7b4d 2020-12-26 op model, to give anyone who possesses the object code either (1) a
263 406d7b4d 2020-12-26 op copy of the Corresponding Source for all the software in the
264 406d7b4d 2020-12-26 op product that is covered by this License, on a durable physical
265 406d7b4d 2020-12-26 op medium customarily used for software interchange, for a price no
266 406d7b4d 2020-12-26 op more than your reasonable cost of physically performing this
267 406d7b4d 2020-12-26 op conveying of source, or (2) access to copy the
268 406d7b4d 2020-12-26 op Corresponding Source from a network server at no charge.
270 406d7b4d 2020-12-26 op c) Convey individual copies of the object code with a copy of the
271 406d7b4d 2020-12-26 op written offer to provide the Corresponding Source. This
272 406d7b4d 2020-12-26 op alternative is allowed only occasionally and noncommercially, and
273 406d7b4d 2020-12-26 op only if you received the object code with such an offer, in accord
274 406d7b4d 2020-12-26 op with subsection 6b.
276 406d7b4d 2020-12-26 op d) Convey the object code by offering access from a designated
277 406d7b4d 2020-12-26 op place (gratis or for a charge), and offer equivalent access to the
278 406d7b4d 2020-12-26 op Corresponding Source in the same way through the same place at no
279 406d7b4d 2020-12-26 op further charge. You need not require recipients to copy the
280 406d7b4d 2020-12-26 op Corresponding Source along with the object code. If the place to
281 406d7b4d 2020-12-26 op copy the object code is a network server, the Corresponding Source
282 406d7b4d 2020-12-26 op may be on a different server (operated by you or a third party)
283 406d7b4d 2020-12-26 op that supports equivalent copying facilities, provided you maintain
284 406d7b4d 2020-12-26 op clear directions next to the object code saying where to find the
285 406d7b4d 2020-12-26 op Corresponding Source. Regardless of what server hosts the
286 406d7b4d 2020-12-26 op Corresponding Source, you remain obligated to ensure that it is
287 406d7b4d 2020-12-26 op available for as long as needed to satisfy these requirements.
289 406d7b4d 2020-12-26 op e) Convey the object code using peer-to-peer transmission, provided
290 406d7b4d 2020-12-26 op you inform other peers where the object code and Corresponding
291 406d7b4d 2020-12-26 op Source of the work are being offered to the general public at no
292 406d7b4d 2020-12-26 op charge under subsection 6d.
294 406d7b4d 2020-12-26 op A separable portion of the object code, whose source code is excluded
295 406d7b4d 2020-12-26 op from the Corresponding Source as a System Library, need not be
296 406d7b4d 2020-12-26 op included in conveying the object code work.
298 406d7b4d 2020-12-26 op A "User Product" is either (1) a "consumer product", which means any
299 406d7b4d 2020-12-26 op tangible personal property which is normally used for personal, family,
300 406d7b4d 2020-12-26 op or household purposes, or (2) anything designed or sold for incorporation
301 406d7b4d 2020-12-26 op into a dwelling. In determining whether a product is a consumer product,
302 406d7b4d 2020-12-26 op doubtful cases shall be resolved in favor of coverage. For a particular
303 406d7b4d 2020-12-26 op product received by a particular user, "normally used" refers to a
304 406d7b4d 2020-12-26 op typical or common use of that class of product, regardless of the status
305 406d7b4d 2020-12-26 op of the particular user or of the way in which the particular user
306 406d7b4d 2020-12-26 op actually uses, or expects or is expected to use, the product. A product
307 406d7b4d 2020-12-26 op is a consumer product regardless of whether the product has substantial
308 406d7b4d 2020-12-26 op commercial, industrial or non-consumer uses, unless such uses represent
309 406d7b4d 2020-12-26 op the only significant mode of use of the product.
311 406d7b4d 2020-12-26 op "Installation Information" for a User Product means any methods,
312 406d7b4d 2020-12-26 op procedures, authorization keys, or other information required to install
313 406d7b4d 2020-12-26 op and execute modified versions of a covered work in that User Product from
314 406d7b4d 2020-12-26 op a modified version of its Corresponding Source. The information must
315 406d7b4d 2020-12-26 op suffice to ensure that the continued functioning of the modified object
316 406d7b4d 2020-12-26 op code is in no case prevented or interfered with solely because
317 406d7b4d 2020-12-26 op modification has been made.
319 406d7b4d 2020-12-26 op If you convey an object code work under this section in, or with, or
320 406d7b4d 2020-12-26 op specifically for use in, a User Product, and the conveying occurs as
321 406d7b4d 2020-12-26 op part of a transaction in which the right of possession and use of the
322 406d7b4d 2020-12-26 op User Product is transferred to the recipient in perpetuity or for a
323 406d7b4d 2020-12-26 op fixed term (regardless of how the transaction is characterized), the
324 406d7b4d 2020-12-26 op Corresponding Source conveyed under this section must be accompanied
325 406d7b4d 2020-12-26 op by the Installation Information. But this requirement does not apply
326 406d7b4d 2020-12-26 op if neither you nor any third party retains the ability to install
327 406d7b4d 2020-12-26 op modified object code on the User Product (for example, the work has
328 406d7b4d 2020-12-26 op been installed in ROM).
330 406d7b4d 2020-12-26 op The requirement to provide Installation Information does not include a
331 406d7b4d 2020-12-26 op requirement to continue to provide support service, warranty, or updates
332 406d7b4d 2020-12-26 op for a work that has been modified or installed by the recipient, or for
333 406d7b4d 2020-12-26 op the User Product in which it has been modified or installed. Access to a
334 406d7b4d 2020-12-26 op network may be denied when the modification itself materially and
335 406d7b4d 2020-12-26 op adversely affects the operation of the network or violates the rules and
336 406d7b4d 2020-12-26 op protocols for communication across the network.
338 406d7b4d 2020-12-26 op Corresponding Source conveyed, and Installation Information provided,
339 406d7b4d 2020-12-26 op in accord with this section must be in a format that is publicly
340 406d7b4d 2020-12-26 op documented (and with an implementation available to the public in
341 406d7b4d 2020-12-26 op source code form), and must require no special password or key for
342 406d7b4d 2020-12-26 op unpacking, reading or copying.
344 406d7b4d 2020-12-26 op 7. Additional Terms.
346 406d7b4d 2020-12-26 op "Additional permissions" are terms that supplement the terms of this
347 406d7b4d 2020-12-26 op License by making exceptions from one or more of its conditions.
348 406d7b4d 2020-12-26 op Additional permissions that are applicable to the entire Program shall
349 406d7b4d 2020-12-26 op be treated as though they were included in this License, to the extent
350 406d7b4d 2020-12-26 op that they are valid under applicable law. If additional permissions
351 406d7b4d 2020-12-26 op apply only to part of the Program, that part may be used separately
352 406d7b4d 2020-12-26 op under those permissions, but the entire Program remains governed by
353 406d7b4d 2020-12-26 op this License without regard to the additional permissions.
355 406d7b4d 2020-12-26 op When you convey a copy of a covered work, you may at your option
356 406d7b4d 2020-12-26 op remove any additional permissions from that copy, or from any part of
357 406d7b4d 2020-12-26 op it. (Additional permissions may be written to require their own
358 406d7b4d 2020-12-26 op removal in certain cases when you modify the work.) You may place
359 406d7b4d 2020-12-26 op additional permissions on material, added by you to a covered work,
360 406d7b4d 2020-12-26 op for which you have or can give appropriate copyright permission.
362 406d7b4d 2020-12-26 op Notwithstanding any other provision of this License, for material you
363 406d7b4d 2020-12-26 op add to a covered work, you may (if authorized by the copyright holders of
364 406d7b4d 2020-12-26 op that material) supplement the terms of this License with terms:
366 406d7b4d 2020-12-26 op a) Disclaiming warranty or limiting liability differently from the
367 406d7b4d 2020-12-26 op terms of sections 15 and 16 of this License; or
369 406d7b4d 2020-12-26 op b) Requiring preservation of specified reasonable legal notices or
370 406d7b4d 2020-12-26 op author attributions in that material or in the Appropriate Legal
371 406d7b4d 2020-12-26 op Notices displayed by works containing it; or
373 406d7b4d 2020-12-26 op c) Prohibiting misrepresentation of the origin of that material, or
374 406d7b4d 2020-12-26 op requiring that modified versions of such material be marked in
375 406d7b4d 2020-12-26 op reasonable ways as different from the original version; or
377 406d7b4d 2020-12-26 op d) Limiting the use for publicity purposes of names of licensors or
378 406d7b4d 2020-12-26 op authors of the material; or
380 406d7b4d 2020-12-26 op e) Declining to grant rights under trademark law for use of some
381 406d7b4d 2020-12-26 op trade names, trademarks, or service marks; or
383 406d7b4d 2020-12-26 op f) Requiring indemnification of licensors and authors of that
384 406d7b4d 2020-12-26 op material by anyone who conveys the material (or modified versions of
385 406d7b4d 2020-12-26 op it) with contractual assumptions of liability to the recipient, for
386 406d7b4d 2020-12-26 op any liability that these contractual assumptions directly impose on
387 406d7b4d 2020-12-26 op those licensors and authors.
389 406d7b4d 2020-12-26 op All other non-permissive additional terms are considered "further
390 406d7b4d 2020-12-26 op restrictions" within the meaning of section 10. If the Program as you
391 406d7b4d 2020-12-26 op received it, or any part of it, contains a notice stating that it is
392 406d7b4d 2020-12-26 op governed by this License along with a term that is a further
393 406d7b4d 2020-12-26 op restriction, you may remove that term. If a license document contains
394 406d7b4d 2020-12-26 op a further restriction but permits relicensing or conveying under this
395 406d7b4d 2020-12-26 op License, you may add to a covered work material governed by the terms
396 406d7b4d 2020-12-26 op of that license document, provided that the further restriction does
397 406d7b4d 2020-12-26 op not survive such relicensing or conveying.
399 406d7b4d 2020-12-26 op If you add terms to a covered work in accord with this section, you
400 406d7b4d 2020-12-26 op must place, in the relevant source files, a statement of the
401 406d7b4d 2020-12-26 op additional terms that apply to those files, or a notice indicating
402 406d7b4d 2020-12-26 op where to find the applicable terms.
404 406d7b4d 2020-12-26 op Additional terms, permissive or non-permissive, may be stated in the
405 406d7b4d 2020-12-26 op form of a separately written license, or stated as exceptions;
406 406d7b4d 2020-12-26 op the above requirements apply either way.
408 406d7b4d 2020-12-26 op 8. Termination.
410 406d7b4d 2020-12-26 op You may not propagate or modify a covered work except as expressly
411 406d7b4d 2020-12-26 op provided under this License. Any attempt otherwise to propagate or
412 406d7b4d 2020-12-26 op modify it is void, and will automatically terminate your rights under
413 406d7b4d 2020-12-26 op this License (including any patent licenses granted under the third
414 406d7b4d 2020-12-26 op paragraph of section 11).
416 406d7b4d 2020-12-26 op However, if you cease all violation of this License, then your
417 406d7b4d 2020-12-26 op license from a particular copyright holder is reinstated (a)
418 406d7b4d 2020-12-26 op provisionally, unless and until the copyright holder explicitly and
419 406d7b4d 2020-12-26 op finally terminates your license, and (b) permanently, if the copyright
420 406d7b4d 2020-12-26 op holder fails to notify you of the violation by some reasonable means
421 406d7b4d 2020-12-26 op prior to 60 days after the cessation.
423 406d7b4d 2020-12-26 op Moreover, your license from a particular copyright holder is
424 406d7b4d 2020-12-26 op reinstated permanently if the copyright holder notifies you of the
425 406d7b4d 2020-12-26 op violation by some reasonable means, this is the first time you have
426 406d7b4d 2020-12-26 op received notice of violation of this License (for any work) from that
427 406d7b4d 2020-12-26 op copyright holder, and you cure the violation prior to 30 days after
428 406d7b4d 2020-12-26 op your receipt of the notice.
430 406d7b4d 2020-12-26 op Termination of your rights under this section does not terminate the
431 406d7b4d 2020-12-26 op licenses of parties who have received copies or rights from you under
432 406d7b4d 2020-12-26 op this License. If your rights have been terminated and not permanently
433 406d7b4d 2020-12-26 op reinstated, you do not qualify to receive new licenses for the same
434 406d7b4d 2020-12-26 op material under section 10.
436 406d7b4d 2020-12-26 op 9. Acceptance Not Required for Having Copies.
438 406d7b4d 2020-12-26 op You are not required to accept this License in order to receive or
439 406d7b4d 2020-12-26 op run a copy of the Program. Ancillary propagation of a covered work
440 406d7b4d 2020-12-26 op occurring solely as a consequence of using peer-to-peer transmission
441 406d7b4d 2020-12-26 op to receive a copy likewise does not require acceptance. However,
442 406d7b4d 2020-12-26 op nothing other than this License grants you permission to propagate or
443 406d7b4d 2020-12-26 op modify any covered work. These actions infringe copyright if you do
444 406d7b4d 2020-12-26 op not accept this License. Therefore, by modifying or propagating a
445 406d7b4d 2020-12-26 op covered work, you indicate your acceptance of this License to do so.
447 406d7b4d 2020-12-26 op 10. Automatic Licensing of Downstream Recipients.
449 406d7b4d 2020-12-26 op Each time you convey a covered work, the recipient automatically
450 406d7b4d 2020-12-26 op receives a license from the original licensors, to run, modify and
451 406d7b4d 2020-12-26 op propagate that work, subject to this License. You are not responsible
452 406d7b4d 2020-12-26 op for enforcing compliance by third parties with this License.
454 406d7b4d 2020-12-26 op An "entity transaction" is a transaction transferring control of an
455 406d7b4d 2020-12-26 op organization, or substantially all assets of one, or subdividing an
456 406d7b4d 2020-12-26 op organization, or merging organizations. If propagation of a covered
457 406d7b4d 2020-12-26 op work results from an entity transaction, each party to that
458 406d7b4d 2020-12-26 op transaction who receives a copy of the work also receives whatever
459 406d7b4d 2020-12-26 op licenses to the work the party's predecessor in interest had or could
460 406d7b4d 2020-12-26 op give under the previous paragraph, plus a right to possession of the
461 406d7b4d 2020-12-26 op Corresponding Source of the work from the predecessor in interest, if
462 406d7b4d 2020-12-26 op the predecessor has it or can get it with reasonable efforts.
464 406d7b4d 2020-12-26 op You may not impose any further restrictions on the exercise of the
465 406d7b4d 2020-12-26 op rights granted or affirmed under this License. For example, you may
466 406d7b4d 2020-12-26 op not impose a license fee, royalty, or other charge for exercise of
467 406d7b4d 2020-12-26 op rights granted under this License, and you may not initiate litigation
468 406d7b4d 2020-12-26 op (including a cross-claim or counterclaim in a lawsuit) alleging that
469 406d7b4d 2020-12-26 op any patent claim is infringed by making, using, selling, offering for
470 406d7b4d 2020-12-26 op sale, or importing the Program or any portion of it.
474 406d7b4d 2020-12-26 op A "contributor" is a copyright holder who authorizes use under this
475 406d7b4d 2020-12-26 op License of the Program or a work on which the Program is based. The
476 406d7b4d 2020-12-26 op work thus licensed is called the contributor's "contributor version".
478 406d7b4d 2020-12-26 op A contributor's "essential patent claims" are all patent claims
479 406d7b4d 2020-12-26 op owned or controlled by the contributor, whether already acquired or
480 406d7b4d 2020-12-26 op hereafter acquired, that would be infringed by some manner, permitted
481 406d7b4d 2020-12-26 op by this License, of making, using, or selling its contributor version,
482 406d7b4d 2020-12-26 op but do not include claims that would be infringed only as a
483 406d7b4d 2020-12-26 op consequence of further modification of the contributor version. For
484 406d7b4d 2020-12-26 op purposes of this definition, "control" includes the right to grant
485 406d7b4d 2020-12-26 op patent sublicenses in a manner consistent with the requirements of
486 406d7b4d 2020-12-26 op this License.
488 406d7b4d 2020-12-26 op Each contributor grants you a non-exclusive, worldwide, royalty-free
489 406d7b4d 2020-12-26 op patent license under the contributor's essential patent claims, to
490 406d7b4d 2020-12-26 op make, use, sell, offer for sale, import and otherwise run, modify and
491 406d7b4d 2020-12-26 op propagate the contents of its contributor version.
493 406d7b4d 2020-12-26 op In the following three paragraphs, a "patent license" is any express
494 406d7b4d 2020-12-26 op agreement or commitment, however denominated, not to enforce a patent
495 406d7b4d 2020-12-26 op (such as an express permission to practice a patent or covenant not to
496 406d7b4d 2020-12-26 op sue for patent infringement). To "grant" such a patent license to a
497 406d7b4d 2020-12-26 op party means to make such an agreement or commitment not to enforce a
498 406d7b4d 2020-12-26 op patent against the party.
500 406d7b4d 2020-12-26 op If you convey a covered work, knowingly relying on a patent license,
501 406d7b4d 2020-12-26 op and the Corresponding Source of the work is not available for anyone
502 406d7b4d 2020-12-26 op to copy, free of charge and under the terms of this License, through a
503 406d7b4d 2020-12-26 op publicly available network server or other readily accessible means,
504 406d7b4d 2020-12-26 op then you must either (1) cause the Corresponding Source to be so
505 406d7b4d 2020-12-26 op available, or (2) arrange to deprive yourself of the benefit of the
506 406d7b4d 2020-12-26 op patent license for this particular work, or (3) arrange, in a manner
507 406d7b4d 2020-12-26 op consistent with the requirements of this License, to extend the patent
508 406d7b4d 2020-12-26 op license to downstream recipients. "Knowingly relying" means you have
509 406d7b4d 2020-12-26 op actual knowledge that, but for the patent license, your conveying the
510 406d7b4d 2020-12-26 op covered work in a country, or your recipient's use of the covered work
511 406d7b4d 2020-12-26 op in a country, would infringe one or more identifiable patents in that
512 406d7b4d 2020-12-26 op country that you have reason to believe are valid.
514 406d7b4d 2020-12-26 op If, pursuant to or in connection with a single transaction or
515 406d7b4d 2020-12-26 op arrangement, you convey, or propagate by procuring conveyance of, a
516 406d7b4d 2020-12-26 op covered work, and grant a patent license to some of the parties
517 406d7b4d 2020-12-26 op receiving the covered work authorizing them to use, propagate, modify
518 406d7b4d 2020-12-26 op or convey a specific copy of the covered work, then the patent license
519 406d7b4d 2020-12-26 op you grant is automatically extended to all recipients of the covered
520 406d7b4d 2020-12-26 op work and works based on it.
522 406d7b4d 2020-12-26 op A patent license is "discriminatory" if it does not include within
523 406d7b4d 2020-12-26 op the scope of its coverage, prohibits the exercise of, or is
524 406d7b4d 2020-12-26 op conditioned on the non-exercise of one or more of the rights that are
525 406d7b4d 2020-12-26 op specifically granted under this License. You may not convey a covered
526 406d7b4d 2020-12-26 op work if you are a party to an arrangement with a third party that is
527 406d7b4d 2020-12-26 op in the business of distributing software, under which you make payment
528 406d7b4d 2020-12-26 op to the third party based on the extent of your activity of conveying
529 406d7b4d 2020-12-26 op the work, and under which the third party grants, to any of the
530 406d7b4d 2020-12-26 op parties who would receive the covered work from you, a discriminatory
531 406d7b4d 2020-12-26 op patent license (a) in connection with copies of the covered work
532 406d7b4d 2020-12-26 op conveyed by you (or copies made from those copies), or (b) primarily
533 406d7b4d 2020-12-26 op for and in connection with specific products or compilations that
534 406d7b4d 2020-12-26 op contain the covered work, unless you entered into that arrangement,
535 406d7b4d 2020-12-26 op or that patent license was granted, prior to 28 March 2007.
537 406d7b4d 2020-12-26 op Nothing in this License shall be construed as excluding or limiting
538 406d7b4d 2020-12-26 op any implied license or other defenses to infringement that may
539 406d7b4d 2020-12-26 op otherwise be available to you under applicable patent law.
541 406d7b4d 2020-12-26 op 12. No Surrender of Others' Freedom.
543 406d7b4d 2020-12-26 op If conditions are imposed on you (whether by court order, agreement or
544 406d7b4d 2020-12-26 op otherwise) that contradict the conditions of this License, they do not
545 406d7b4d 2020-12-26 op excuse you from the conditions of this License. If you cannot convey a
546 406d7b4d 2020-12-26 op covered work so as to satisfy simultaneously your obligations under this
547 406d7b4d 2020-12-26 op License and any other pertinent obligations, then as a consequence you may
548 406d7b4d 2020-12-26 op not convey it at all. For example, if you agree to terms that obligate you
549 406d7b4d 2020-12-26 op to collect a royalty for further conveying from those to whom you convey
550 406d7b4d 2020-12-26 op the Program, the only way you could satisfy both those terms and this
551 406d7b4d 2020-12-26 op License would be to refrain entirely from conveying the Program.
553 406d7b4d 2020-12-26 op 13. Use with the GNU Affero General Public License.
555 406d7b4d 2020-12-26 op Notwithstanding any other provision of this License, you have
556 406d7b4d 2020-12-26 op permission to link or combine any covered work with a work licensed
557 406d7b4d 2020-12-26 op under version 3 of the GNU Affero General Public License into a single
558 406d7b4d 2020-12-26 op combined work, and to convey the resulting work. The terms of this
559 406d7b4d 2020-12-26 op License will continue to apply to the part which is the covered work,
560 406d7b4d 2020-12-26 op but the special requirements of the GNU Affero General Public License,
561 406d7b4d 2020-12-26 op section 13, concerning interaction through a network will apply to the
562 406d7b4d 2020-12-26 op combination as such.
564 406d7b4d 2020-12-26 op 14. Revised Versions of this License.
566 406d7b4d 2020-12-26 op The Free Software Foundation may publish revised and/or new versions of
567 406d7b4d 2020-12-26 op the GNU General Public License from time to time. Such new versions will
568 406d7b4d 2020-12-26 op be similar in spirit to the present version, but may differ in detail to
569 406d7b4d 2020-12-26 op address new problems or concerns.
571 406d7b4d 2020-12-26 op Each version is given a distinguishing version number. If the
572 406d7b4d 2020-12-26 op Program specifies that a certain numbered version of the GNU General
573 406d7b4d 2020-12-26 op Public License "or any later version" applies to it, you have the
574 406d7b4d 2020-12-26 op option of following the terms and conditions either of that numbered
575 406d7b4d 2020-12-26 op version or of any later version published by the Free Software
576 406d7b4d 2020-12-26 op Foundation. If the Program does not specify a version number of the
577 406d7b4d 2020-12-26 op GNU General Public License, you may choose any version ever published
578 406d7b4d 2020-12-26 op by the Free Software Foundation.
580 406d7b4d 2020-12-26 op If the Program specifies that a proxy can decide which future
581 406d7b4d 2020-12-26 op versions of the GNU General Public License can be used, that proxy's
582 406d7b4d 2020-12-26 op public statement of acceptance of a version permanently authorizes you
583 406d7b4d 2020-12-26 op to choose that version for the Program.
585 406d7b4d 2020-12-26 op Later license versions may give you additional or different
586 406d7b4d 2020-12-26 op permissions. However, no additional obligations are imposed on any
587 406d7b4d 2020-12-26 op author or copyright holder as a result of your choosing to follow a
588 406d7b4d 2020-12-26 op later version.
590 406d7b4d 2020-12-26 op 15. Disclaimer of Warranty.
592 406d7b4d 2020-12-26 op THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
593 406d7b4d 2020-12-26 op APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
594 406d7b4d 2020-12-26 op HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
595 406d7b4d 2020-12-26 op OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
596 406d7b4d 2020-12-26 op THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
597 406d7b4d 2020-12-26 op PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
598 406d7b4d 2020-12-26 op IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
599 406d7b4d 2020-12-26 op ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
601 406d7b4d 2020-12-26 op 16. Limitation of Liability.
603 406d7b4d 2020-12-26 op IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
604 406d7b4d 2020-12-26 op WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
605 406d7b4d 2020-12-26 op THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
606 406d7b4d 2020-12-26 op GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
607 406d7b4d 2020-12-26 op USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
608 406d7b4d 2020-12-26 op DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
609 406d7b4d 2020-12-26 op PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
610 406d7b4d 2020-12-26 op EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
611 406d7b4d 2020-12-26 op SUCH DAMAGES.
613 406d7b4d 2020-12-26 op 17. Interpretation of Sections 15 and 16.
615 406d7b4d 2020-12-26 op If the disclaimer of warranty and limitation of liability provided
616 406d7b4d 2020-12-26 op above cannot be given local legal effect according to their terms,
617 406d7b4d 2020-12-26 op reviewing courts shall apply local law that most closely approximates
618 406d7b4d 2020-12-26 op an absolute waiver of all civil liability in connection with the
619 406d7b4d 2020-12-26 op Program, unless a warranty or assumption of liability accompanies a
620 406d7b4d 2020-12-26 op copy of the Program in return for a fee.
622 406d7b4d 2020-12-26 op END OF TERMS AND CONDITIONS
624 406d7b4d 2020-12-26 op How to Apply These Terms to Your New Programs
626 406d7b4d 2020-12-26 op If you develop a new program, and you want it to be of the greatest
627 406d7b4d 2020-12-26 op possible use to the public, the best way to achieve this is to make it
628 406d7b4d 2020-12-26 op free software which everyone can redistribute and change under these terms.
630 406d7b4d 2020-12-26 op To do so, attach the following notices to the program. It is safest
631 406d7b4d 2020-12-26 op to attach them to the start of each source file to most effectively
632 406d7b4d 2020-12-26 op state the exclusion of warranty; and each file should have at least
633 406d7b4d 2020-12-26 op the "copyright" line and a pointer to where the full notice is found.
635 406d7b4d 2020-12-26 op <one line to give the program's name and a brief idea of what it does.>
636 406d7b4d 2020-12-26 op Copyright (C) <year> <name of author>
638 406d7b4d 2020-12-26 op This program is free software: you can redistribute it and/or modify
639 406d7b4d 2020-12-26 op it under the terms of the GNU General Public License as published by
640 406d7b4d 2020-12-26 op the Free Software Foundation, either version 3 of the License, or
641 406d7b4d 2020-12-26 op (at your option) any later version.
643 406d7b4d 2020-12-26 op This program is distributed in the hope that it will be useful,
644 406d7b4d 2020-12-26 op but WITHOUT ANY WARRANTY; without even the implied warranty of
645 406d7b4d 2020-12-26 op MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the

648 406d7b4d 2020-12-26 op You should have received a copy of the GNU General Public License
649 406d7b4d 2020-12-26 op along with this program. If not, see <http://www.gnu.org/licenses/>.
651 406d7b4d 2020-12-26 op Also add information on how to contact you by electronic and paper mail.
653 406d7b4d 2020-12-26 op If the program does terminal interaction, make it output a short
654 406d7b4d 2020-12-26 op notice like this when it starts in an interactive mode:
656 406d7b4d 2020-12-26 op <program> Copyright (C) <year> <name of author>
657 406d7b4d 2020-12-26 op This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
658 406d7b4d 2020-12-26 op This is free software, and you are welcome to redistribute it
659 406d7b4d 2020-12-26 op under certain conditions; type `show c' for details.
661 406d7b4d 2020-12-26 op The hypothetical commands `show w' and `show c' should show the appropriate
662 406d7b4d 2020-12-26 op parts of the General Public License. Of course, your program's commands
663 406d7b4d 2020-12-26 op might be different; for a GUI interface, you would use an "about box".
665 406d7b4d 2020-12-26 op You should also get your employer (if you work as a programmer) or school,
666 406d7b4d 2020-12-26 op if any, to sign a "copyright disclaimer" for the program, if necessary.

672 406d7b4d 2020-12-26 op may consider it more useful to permit linking proprietary applications with
