2 4347b5b9 2021-07-09 lh Version 3, 29 June 2007
4 4347b5b9 2021-07-09 lh Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
5 4347b5b9 2021-07-09 lh Everyone is permitted to copy and distribute verbatim copies
6 4347b5b9 2021-07-09 lh of this license document, but changing it is not allowed.
10 4347b5b9 2021-07-09 lh The GNU General Public License is a free, copyleft license for
11 4347b5b9 2021-07-09 lh software and other kinds of works.
13 4347b5b9 2021-07-09 lh The licenses for most software and other practical works are designed
14 4347b5b9 2021-07-09 lh to take away your freedom to share and change the works. By contrast,
15 4347b5b9 2021-07-09 lh the GNU General Public License is intended to guarantee your freedom to
16 4347b5b9 2021-07-09 lh share and change all versions of a program--to make sure it remains free
17 4347b5b9 2021-07-09 lh software for all its users. We, the Free Software Foundation, use the
18 4347b5b9 2021-07-09 lh GNU General Public License for most of our software; it applies also to
19 4347b5b9 2021-07-09 lh any other work released this way by its authors. You can apply it to
20 4347b5b9 2021-07-09 lh your programs, too.
22 4347b5b9 2021-07-09 lh When we speak of free software, we are referring to freedom, not
23 4347b5b9 2021-07-09 lh price. Our General Public Licenses are designed to make sure that you
24 4347b5b9 2021-07-09 lh have the freedom to distribute copies of free software (and charge for
25 4347b5b9 2021-07-09 lh them if you wish), that you receive source code or can get it if you
26 4347b5b9 2021-07-09 lh want it, that you can change the software or use pieces of it in new
27 4347b5b9 2021-07-09 lh free programs, and that you know you can do these things.
29 4347b5b9 2021-07-09 lh To protect your rights, we need to prevent others from denying you
30 4347b5b9 2021-07-09 lh these rights or asking you to surrender the rights. Therefore, you have
31 4347b5b9 2021-07-09 lh certain responsibilities if you distribute copies of the software, or if
32 4347b5b9 2021-07-09 lh you modify it: responsibilities to respect the freedom of others.
34 4347b5b9 2021-07-09 lh For example, if you distribute copies of such a program, whether
35 4347b5b9 2021-07-09 lh gratis or for a fee, you must pass on to the recipients the same
36 4347b5b9 2021-07-09 lh freedoms that you received. You must make sure that they, too, receive
37 4347b5b9 2021-07-09 lh or can get the source code. And you must show them these terms so they
38 4347b5b9 2021-07-09 lh know their rights.
40 4347b5b9 2021-07-09 lh Developers that use the GNU GPL protect your rights with two steps:
41 4347b5b9 2021-07-09 lh (1) assert copyright on the software, and (2) offer you this License
42 4347b5b9 2021-07-09 lh giving you legal permission to copy, distribute and/or modify it.
44 4347b5b9 2021-07-09 lh For the developers' and authors' protection, the GPL clearly explains
45 4347b5b9 2021-07-09 lh that there is no warranty for this free software. For both users' and
46 4347b5b9 2021-07-09 lh authors' sake, the GPL requires that modified versions be marked as
47 4347b5b9 2021-07-09 lh changed, so that their problems will not be attributed erroneously to
48 4347b5b9 2021-07-09 lh authors of previous versions.
50 4347b5b9 2021-07-09 lh Some devices are designed to deny users access to install or run
51 4347b5b9 2021-07-09 lh modified versions of the software inside them, although the manufacturer
52 4347b5b9 2021-07-09 lh can do so. This is fundamentally incompatible with the aim of
53 4347b5b9 2021-07-09 lh protecting users' freedom to change the software. The systematic
54 4347b5b9 2021-07-09 lh pattern of such abuse occurs in the area of products for individuals to
55 4347b5b9 2021-07-09 lh use, which is precisely where it is most unacceptable. Therefore, we
56 4347b5b9 2021-07-09 lh have designed this version of the GPL to prohibit the practice for those
57 4347b5b9 2021-07-09 lh products. If such problems arise substantially in other domains, we
58 4347b5b9 2021-07-09 lh stand ready to extend this provision to those domains in future versions
59 4347b5b9 2021-07-09 lh of the GPL, as needed to protect the freedom of users.
61 4347b5b9 2021-07-09 lh Finally, every program is threatened constantly by software patents.
62 4347b5b9 2021-07-09 lh States should not allow patents to restrict development and use of
63 4347b5b9 2021-07-09 lh software on general-purpose computers, but in those that do, we wish to
64 4347b5b9 2021-07-09 lh avoid the special danger that patents applied to a free program could
65 4347b5b9 2021-07-09 lh make it effectively proprietary. To prevent this, the GPL assures that
66 4347b5b9 2021-07-09 lh patents cannot be used to render the program non-free.
68 4347b5b9 2021-07-09 lh The precise terms and conditions for copying, distribution and
69 4347b5b9 2021-07-09 lh modification follow.
71 4347b5b9 2021-07-09 lh TERMS AND CONDITIONS
73 4347b5b9 2021-07-09 lh 0. Definitions.
75 4347b5b9 2021-07-09 lh "This License" refers to version 3 of the GNU General Public License.
77 4347b5b9 2021-07-09 lh "Copyright" also means copyright-like laws that apply to other kinds of
78 4347b5b9 2021-07-09 lh works, such as semiconductor masks.
80 4347b5b9 2021-07-09 lh "The Program" refers to any copyrightable work licensed under this
81 4347b5b9 2021-07-09 lh License. Each licensee is addressed as "you". "Licensees" and
82 4347b5b9 2021-07-09 lh "recipients" may be individuals or organizations.
84 4347b5b9 2021-07-09 lh To "modify" a work means to copy from or adapt all or part of the work
85 4347b5b9 2021-07-09 lh in a fashion requiring copyright permission, other than the making of an
86 4347b5b9 2021-07-09 lh exact copy. The resulting work is called a "modified version" of the
87 4347b5b9 2021-07-09 lh earlier work or a work "based on" the earlier work.
89 4347b5b9 2021-07-09 lh A "covered work" means either the unmodified Program or a work based
90 4347b5b9 2021-07-09 lh on the Program.
92 4347b5b9 2021-07-09 lh To "propagate" a work means to do anything with it that, without
93 4347b5b9 2021-07-09 lh permission, would make you directly or secondarily liable for
94 4347b5b9 2021-07-09 lh infringement under applicable copyright law, except executing it on a
95 4347b5b9 2021-07-09 lh computer or modifying a private copy. Propagation includes copying,
96 4347b5b9 2021-07-09 lh distribution (with or without modification), making available to the
97 4347b5b9 2021-07-09 lh public, and in some countries other activities as well.
99 4347b5b9 2021-07-09 lh To "convey" a work means any kind of propagation that enables other
100 4347b5b9 2021-07-09 lh parties to make or receive copies. Mere interaction with a user through
101 4347b5b9 2021-07-09 lh a computer network, with no transfer of a copy, is not conveying.
103 4347b5b9 2021-07-09 lh An interactive user interface displays "Appropriate Legal Notices"
104 4347b5b9 2021-07-09 lh to the extent that it includes a convenient and prominently visible
105 4347b5b9 2021-07-09 lh feature that (1) displays an appropriate copyright notice, and (2)
106 4347b5b9 2021-07-09 lh tells the user that there is no warranty for the work (except to the
107 4347b5b9 2021-07-09 lh extent that warranties are provided), that licensees may convey the
108 4347b5b9 2021-07-09 lh work under this License, and how to view a copy of this License. If
109 4347b5b9 2021-07-09 lh the interface presents a list of user commands or options, such as a
110 4347b5b9 2021-07-09 lh menu, a prominent item in the list meets this criterion.
112 4347b5b9 2021-07-09 lh 1. Source Code.
114 4347b5b9 2021-07-09 lh The "source code" for a work means the preferred form of the work
115 4347b5b9 2021-07-09 lh for making modifications to it. "Object code" means any non-source
116 4347b5b9 2021-07-09 lh form of a work.
118 4347b5b9 2021-07-09 lh A "Standard Interface" means an interface that either is an official
119 4347b5b9 2021-07-09 lh standard defined by a recognized standards body, or, in the case of
120 4347b5b9 2021-07-09 lh interfaces specified for a particular programming language, one that
121 4347b5b9 2021-07-09 lh is widely used among developers working in that language.
123 4347b5b9 2021-07-09 lh The "System Libraries" of an executable work include anything, other
124 4347b5b9 2021-07-09 lh than the work as a whole, that (a) is included in the normal form of
125 4347b5b9 2021-07-09 lh packaging a Major Component, but which is not part of that Major
126 4347b5b9 2021-07-09 lh Component, and (b) serves only to enable use of the work with that
127 4347b5b9 2021-07-09 lh Major Component, or to implement a Standard Interface for which an
128 4347b5b9 2021-07-09 lh implementation is available to the public in source code form. A
129 4347b5b9 2021-07-09 lh "Major Component", in this context, means a major essential component
130 4347b5b9 2021-07-09 lh (kernel, window system, and so on) of the specific operating system
131 4347b5b9 2021-07-09 lh (if any) on which the executable work runs, or a compiler used to
132 4347b5b9 2021-07-09 lh produce the work, or an object code interpreter used to run it.
134 4347b5b9 2021-07-09 lh The "Corresponding Source" for a work in object code form means all
135 4347b5b9 2021-07-09 lh the source code needed to generate, install, and (for an executable
136 4347b5b9 2021-07-09 lh work) run the object code and to modify the work, including scripts to
137 4347b5b9 2021-07-09 lh control those activities. However, it does not include the work's
138 4347b5b9 2021-07-09 lh System Libraries, or general-purpose tools or generally available free
139 4347b5b9 2021-07-09 lh programs which are used unmodified in performing those activities but
140 4347b5b9 2021-07-09 lh which are not part of the work. For example, Corresponding Source
141 4347b5b9 2021-07-09 lh includes interface definition files associated with source files for
142 4347b5b9 2021-07-09 lh the work, and the source code for shared libraries and dynamically
143 4347b5b9 2021-07-09 lh linked subprograms that the work is specifically designed to require,
144 4347b5b9 2021-07-09 lh such as by intimate data communication or control flow between those
145 4347b5b9 2021-07-09 lh subprograms and other parts of the work.
147 4347b5b9 2021-07-09 lh The Corresponding Source need not include anything that users
148 4347b5b9 2021-07-09 lh can regenerate automatically from other parts of the Corresponding
151 4347b5b9 2021-07-09 lh The Corresponding Source for a work in source code form is that
154 4347b5b9 2021-07-09 lh 2. Basic Permissions.
156 4347b5b9 2021-07-09 lh All rights granted under this License are granted for the term of
157 4347b5b9 2021-07-09 lh copyright on the Program, and are irrevocable provided the stated
158 4347b5b9 2021-07-09 lh conditions are met. This License explicitly affirms your unlimited
159 4347b5b9 2021-07-09 lh permission to run the unmodified Program. The output from running a
160 4347b5b9 2021-07-09 lh covered work is covered by this License only if the output, given its
161 4347b5b9 2021-07-09 lh content, constitutes a covered work. This License acknowledges your
162 4347b5b9 2021-07-09 lh rights of fair use or other equivalent, as provided by copyright law.
164 4347b5b9 2021-07-09 lh You may make, run and propagate covered works that you do not
165 4347b5b9 2021-07-09 lh convey, without conditions so long as your license otherwise remains
166 4347b5b9 2021-07-09 lh in force. You may convey covered works to others for the sole purpose
167 4347b5b9 2021-07-09 lh of having them make modifications exclusively for you, or provide you
168 4347b5b9 2021-07-09 lh with facilities for running those works, provided that you comply with
169 4347b5b9 2021-07-09 lh the terms of this License in conveying all material for which you do
170 4347b5b9 2021-07-09 lh not control copyright. Those thus making or running the covered works
171 4347b5b9 2021-07-09 lh for you must do so exclusively on your behalf, under your direction
172 4347b5b9 2021-07-09 lh and control, on terms that prohibit them from making any copies of
173 4347b5b9 2021-07-09 lh your copyrighted material outside their relationship with you.
175 4347b5b9 2021-07-09 lh Conveying under any other circumstances is permitted solely under
176 4347b5b9 2021-07-09 lh the conditions stated below. Sublicensing is not allowed; section 10
177 4347b5b9 2021-07-09 lh makes it unnecessary.
179 4347b5b9 2021-07-09 lh 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
181 4347b5b9 2021-07-09 lh No covered work shall be deemed part of an effective technological
182 4347b5b9 2021-07-09 lh measure under any applicable law fulfilling obligations under article
183 4347b5b9 2021-07-09 lh 11 of the WIPO copyright treaty adopted on 20 December 1996, or
184 4347b5b9 2021-07-09 lh similar laws prohibiting or restricting circumvention of such
187 4347b5b9 2021-07-09 lh When you convey a covered work, you waive any legal power to forbid
188 4347b5b9 2021-07-09 lh circumvention of technological measures to the extent such circumvention
189 4347b5b9 2021-07-09 lh is effected by exercising rights under this License with respect to
190 4347b5b9 2021-07-09 lh the covered work, and you disclaim any intention to limit operation or
191 4347b5b9 2021-07-09 lh modification of the work as a means of enforcing, against the work's
192 4347b5b9 2021-07-09 lh users, your or third parties' legal rights to forbid circumvention of
193 4347b5b9 2021-07-09 lh technological measures.
195 4347b5b9 2021-07-09 lh 4. Conveying Verbatim Copies.
197 4347b5b9 2021-07-09 lh You may convey verbatim copies of the Program's source code as you
198 4347b5b9 2021-07-09 lh receive it, in any medium, provided that you conspicuously and
199 4347b5b9 2021-07-09 lh appropriately publish on each copy an appropriate copyright notice;
200 4347b5b9 2021-07-09 lh keep intact all notices stating that this License and any
201 4347b5b9 2021-07-09 lh non-permissive terms added in accord with section 7 apply to the code;
202 4347b5b9 2021-07-09 lh keep intact all notices of the absence of any warranty; and give all
203 4347b5b9 2021-07-09 lh recipients a copy of this License along with the Program.
205 4347b5b9 2021-07-09 lh You may charge any price or no price for each copy that you convey,
206 4347b5b9 2021-07-09 lh and you may offer support or warranty protection for a fee.
208 4347b5b9 2021-07-09 lh 5. Conveying Modified Source Versions.
210 4347b5b9 2021-07-09 lh You may convey a work based on the Program, or the modifications to
211 4347b5b9 2021-07-09 lh produce it from the Program, in the form of source code under the
212 4347b5b9 2021-07-09 lh terms of section 4, provided that you also meet all of these conditions:
214 4347b5b9 2021-07-09 lh a) The work must carry prominent notices stating that you modified
215 4347b5b9 2021-07-09 lh it, and giving a relevant date.
217 4347b5b9 2021-07-09 lh b) The work must carry prominent notices stating that it is
218 4347b5b9 2021-07-09 lh released under this License and any conditions added under section
219 4347b5b9 2021-07-09 lh 7. This requirement modifies the requirement in section 4 to
220 4347b5b9 2021-07-09 lh "keep intact all notices".
222 4347b5b9 2021-07-09 lh c) You must license the entire work, as a whole, under this
223 4347b5b9 2021-07-09 lh License to anyone who comes into possession of a copy. This
224 4347b5b9 2021-07-09 lh License will therefore apply, along with any applicable section 7
225 4347b5b9 2021-07-09 lh additional terms, to the whole of the work, and all its parts,
226 4347b5b9 2021-07-09 lh regardless of how they are packaged. This License gives no
227 4347b5b9 2021-07-09 lh permission to license the work in any other way, but it does not
228 4347b5b9 2021-07-09 lh invalidate such permission if you have separately received it.
230 4347b5b9 2021-07-09 lh d) If the work has interactive user interfaces, each must display
231 4347b5b9 2021-07-09 lh Appropriate Legal Notices; however, if the Program has interactive
232 4347b5b9 2021-07-09 lh interfaces that do not display Appropriate Legal Notices, your
233 4347b5b9 2021-07-09 lh work need not make them do so.
235 4347b5b9 2021-07-09 lh A compilation of a covered work with other separate and independent
236 4347b5b9 2021-07-09 lh works, which are not by their nature extensions of the covered work,
237 4347b5b9 2021-07-09 lh and which are not combined with it such as to form a larger program,
238 4347b5b9 2021-07-09 lh in or on a volume of a storage or distribution medium, is called an
239 4347b5b9 2021-07-09 lh "aggregate" if the compilation and its resulting copyright are not
240 4347b5b9 2021-07-09 lh used to limit the access or legal rights of the compilation's users
241 4347b5b9 2021-07-09 lh beyond what the individual works permit. Inclusion of a covered work
242 4347b5b9 2021-07-09 lh in an aggregate does not cause this License to apply to the other
243 4347b5b9 2021-07-09 lh parts of the aggregate.
245 4347b5b9 2021-07-09 lh 6. Conveying Non-Source Forms.
247 4347b5b9 2021-07-09 lh You may convey a covered work in object code form under the terms
248 4347b5b9 2021-07-09 lh of sections 4 and 5, provided that you also convey the
249 4347b5b9 2021-07-09 lh machine-readable Corresponding Source under the terms of this License,
250 4347b5b9 2021-07-09 lh in one of these ways:
252 4347b5b9 2021-07-09 lh a) Convey the object code in, or embodied in, a physical product
253 4347b5b9 2021-07-09 lh (including a physical distribution medium), accompanied by the
254 4347b5b9 2021-07-09 lh Corresponding Source fixed on a durable physical medium
255 4347b5b9 2021-07-09 lh customarily used for software interchange.
257 4347b5b9 2021-07-09 lh b) Convey the object code in, or embodied in, a physical product
258 4347b5b9 2021-07-09 lh (including a physical distribution medium), accompanied by a
259 4347b5b9 2021-07-09 lh written offer, valid for at least three years and valid for as
260 4347b5b9 2021-07-09 lh long as you offer spare parts or customer support for that product
261 4347b5b9 2021-07-09 lh model, to give anyone who possesses the object code either (1) a
262 4347b5b9 2021-07-09 lh copy of the Corresponding Source for all the software in the
263 4347b5b9 2021-07-09 lh product that is covered by this License, on a durable physical
264 4347b5b9 2021-07-09 lh medium customarily used for software interchange, for a price no
265 4347b5b9 2021-07-09 lh more than your reasonable cost of physically performing this
266 4347b5b9 2021-07-09 lh conveying of source, or (2) access to copy the
267 4347b5b9 2021-07-09 lh Corresponding Source from a network server at no charge.
269 4347b5b9 2021-07-09 lh c) Convey individual copies of the object code with a copy of the
270 4347b5b9 2021-07-09 lh written offer to provide the Corresponding Source. This
271 4347b5b9 2021-07-09 lh alternative is allowed only occasionally and noncommercially, and
272 4347b5b9 2021-07-09 lh only if you received the object code with such an offer, in accord
273 4347b5b9 2021-07-09 lh with subsection 6b.
275 4347b5b9 2021-07-09 lh d) Convey the object code by offering access from a designated
276 4347b5b9 2021-07-09 lh place (gratis or for a charge), and offer equivalent access to the
277 4347b5b9 2021-07-09 lh Corresponding Source in the same way through the same place at no
278 4347b5b9 2021-07-09 lh further charge. You need not require recipients to copy the
279 4347b5b9 2021-07-09 lh Corresponding Source along with the object code. If the place to
280 4347b5b9 2021-07-09 lh copy the object code is a network server, the Corresponding Source
281 4347b5b9 2021-07-09 lh may be on a different server (operated by you or a third party)
282 4347b5b9 2021-07-09 lh that supports equivalent copying facilities, provided you maintain
283 4347b5b9 2021-07-09 lh clear directions next to the object code saying where to find the
284 4347b5b9 2021-07-09 lh Corresponding Source. Regardless of what server hosts the
285 4347b5b9 2021-07-09 lh Corresponding Source, you remain obligated to ensure that it is
286 4347b5b9 2021-07-09 lh available for as long as needed to satisfy these requirements.
288 4347b5b9 2021-07-09 lh e) Convey the object code using peer-to-peer transmission, provided
289 4347b5b9 2021-07-09 lh you inform other peers where the object code and Corresponding
290 4347b5b9 2021-07-09 lh Source of the work are being offered to the general public at no
291 4347b5b9 2021-07-09 lh charge under subsection 6d.
293 4347b5b9 2021-07-09 lh A separable portion of the object code, whose source code is excluded
294 4347b5b9 2021-07-09 lh from the Corresponding Source as a System Library, need not be
295 4347b5b9 2021-07-09 lh included in conveying the object code work.
297 4347b5b9 2021-07-09 lh A "User Product" is either (1) a "consumer product", which means any
298 4347b5b9 2021-07-09 lh tangible personal property which is normally used for personal, family,
299 4347b5b9 2021-07-09 lh or household purposes, or (2) anything designed or sold for incorporation
300 4347b5b9 2021-07-09 lh into a dwelling. In determining whether a product is a consumer product,
301 4347b5b9 2021-07-09 lh doubtful cases shall be resolved in favor of coverage. For a particular
302 4347b5b9 2021-07-09 lh product received by a particular user, "normally used" refers to a
303 4347b5b9 2021-07-09 lh typical or common use of that class of product, regardless of the status
304 4347b5b9 2021-07-09 lh of the particular user or of the way in which the particular user
305 4347b5b9 2021-07-09 lh actually uses, or expects or is expected to use, the product. A product
306 4347b5b9 2021-07-09 lh is a consumer product regardless of whether the product has substantial
307 4347b5b9 2021-07-09 lh commercial, industrial or non-consumer uses, unless such uses represent
308 4347b5b9 2021-07-09 lh the only significant mode of use of the product.
310 4347b5b9 2021-07-09 lh "Installation Information" for a User Product means any methods,
311 4347b5b9 2021-07-09 lh procedures, authorization keys, or other information required to install
312 4347b5b9 2021-07-09 lh and execute modified versions of a covered work in that User Product from
313 4347b5b9 2021-07-09 lh a modified version of its Corresponding Source. The information must
314 4347b5b9 2021-07-09 lh suffice to ensure that the continued functioning of the modified object
315 4347b5b9 2021-07-09 lh code is in no case prevented or interfered with solely because
316 4347b5b9 2021-07-09 lh modification has been made.
318 4347b5b9 2021-07-09 lh If you convey an object code work under this section in, or with, or
319 4347b5b9 2021-07-09 lh specifically for use in, a User Product, and the conveying occurs as
320 4347b5b9 2021-07-09 lh part of a transaction in which the right of possession and use of the
321 4347b5b9 2021-07-09 lh User Product is transferred to the recipient in perpetuity or for a
322 4347b5b9 2021-07-09 lh fixed term (regardless of how the transaction is characterized), the
323 4347b5b9 2021-07-09 lh Corresponding Source conveyed under this section must be accompanied
324 4347b5b9 2021-07-09 lh by the Installation Information. But this requirement does not apply
325 4347b5b9 2021-07-09 lh if neither you nor any third party retains the ability to install
326 4347b5b9 2021-07-09 lh modified object code on the User Product (for example, the work has
327 4347b5b9 2021-07-09 lh been installed in ROM).
329 4347b5b9 2021-07-09 lh The requirement to provide Installation Information does not include a
330 4347b5b9 2021-07-09 lh requirement to continue to provide support service, warranty, or updates
331 4347b5b9 2021-07-09 lh for a work that has been modified or installed by the recipient, or for
332 4347b5b9 2021-07-09 lh the User Product in which it has been modified or installed. Access to a
333 4347b5b9 2021-07-09 lh network may be denied when the modification itself materially and
334 4347b5b9 2021-07-09 lh adversely affects the operation of the network or violates the rules and
335 4347b5b9 2021-07-09 lh protocols for communication across the network.
337 4347b5b9 2021-07-09 lh Corresponding Source conveyed, and Installation Information provided,
338 4347b5b9 2021-07-09 lh in accord with this section must be in a format that is publicly
339 4347b5b9 2021-07-09 lh documented (and with an implementation available to the public in
340 4347b5b9 2021-07-09 lh source code form), and must require no special password or key for
341 4347b5b9 2021-07-09 lh unpacking, reading or copying.
343 4347b5b9 2021-07-09 lh 7. Additional Terms.
345 4347b5b9 2021-07-09 lh "Additional permissions" are terms that supplement the terms of this
346 4347b5b9 2021-07-09 lh License by making exceptions from one or more of its conditions.
347 4347b5b9 2021-07-09 lh Additional permissions that are applicable to the entire Program shall
348 4347b5b9 2021-07-09 lh be treated as though they were included in this License, to the extent
349 4347b5b9 2021-07-09 lh that they are valid under applicable law. If additional permissions
350 4347b5b9 2021-07-09 lh apply only to part of the Program, that part may be used separately
351 4347b5b9 2021-07-09 lh under those permissions, but the entire Program remains governed by
352 4347b5b9 2021-07-09 lh this License without regard to the additional permissions.
354 4347b5b9 2021-07-09 lh When you convey a copy of a covered work, you may at your option
355 4347b5b9 2021-07-09 lh remove any additional permissions from that copy, or from any part of
356 4347b5b9 2021-07-09 lh it. (Additional permissions may be written to require their own
357 4347b5b9 2021-07-09 lh removal in certain cases when you modify the work.) You may place
358 4347b5b9 2021-07-09 lh additional permissions on material, added by you to a covered work,
359 4347b5b9 2021-07-09 lh for which you have or can give appropriate copyright permission.
361 4347b5b9 2021-07-09 lh Notwithstanding any other provision of this License, for material you
362 4347b5b9 2021-07-09 lh add to a covered work, you may (if authorized by the copyright holders of
363 4347b5b9 2021-07-09 lh that material) supplement the terms of this License with terms:
365 4347b5b9 2021-07-09 lh a) Disclaiming warranty or limiting liability differently from the
366 4347b5b9 2021-07-09 lh terms of sections 15 and 16 of this License; or
368 4347b5b9 2021-07-09 lh b) Requiring preservation of specified reasonable legal notices or
369 4347b5b9 2021-07-09 lh author attributions in that material or in the Appropriate Legal
370 4347b5b9 2021-07-09 lh Notices displayed by works containing it; or
372 4347b5b9 2021-07-09 lh c) Prohibiting misrepresentation of the origin of that material, or
373 4347b5b9 2021-07-09 lh requiring that modified versions of such material be marked in
374 4347b5b9 2021-07-09 lh reasonable ways as different from the original version; or
376 4347b5b9 2021-07-09 lh d) Limiting the use for publicity purposes of names of licensors or
377 4347b5b9 2021-07-09 lh authors of the material; or
379 4347b5b9 2021-07-09 lh e) Declining to grant rights under trademark law for use of some
380 4347b5b9 2021-07-09 lh trade names, trademarks, or service marks; or
382 4347b5b9 2021-07-09 lh f) Requiring indemnification of licensors and authors of that
383 4347b5b9 2021-07-09 lh material by anyone who conveys the material (or modified versions of
384 4347b5b9 2021-07-09 lh it) with contractual assumptions of liability to the recipient, for
385 4347b5b9 2021-07-09 lh any liability that these contractual assumptions directly impose on
386 4347b5b9 2021-07-09 lh those licensors and authors.
388 4347b5b9 2021-07-09 lh All other non-permissive additional terms are considered "further
389 4347b5b9 2021-07-09 lh restrictions" within the meaning of section 10. If the Program as you
390 4347b5b9 2021-07-09 lh received it, or any part of it, contains a notice stating that it is
391 4347b5b9 2021-07-09 lh governed by this License along with a term that is a further
392 4347b5b9 2021-07-09 lh restriction, you may remove that term. If a license document contains
393 4347b5b9 2021-07-09 lh a further restriction but permits relicensing or conveying under this
394 4347b5b9 2021-07-09 lh License, you may add to a covered work material governed by the terms
395 4347b5b9 2021-07-09 lh of that license document, provided that the further restriction does
396 4347b5b9 2021-07-09 lh not survive such relicensing or conveying.
398 4347b5b9 2021-07-09 lh If you add terms to a covered work in accord with this section, you
399 4347b5b9 2021-07-09 lh must place, in the relevant source files, a statement of the
400 4347b5b9 2021-07-09 lh additional terms that apply to those files, or a notice indicating
401 4347b5b9 2021-07-09 lh where to find the applicable terms.
403 4347b5b9 2021-07-09 lh Additional terms, permissive or non-permissive, may be stated in the
404 4347b5b9 2021-07-09 lh form of a separately written license, or stated as exceptions;
405 4347b5b9 2021-07-09 lh the above requirements apply either way.
407 4347b5b9 2021-07-09 lh 8. Termination.
409 4347b5b9 2021-07-09 lh You may not propagate or modify a covered work except as expressly
410 4347b5b9 2021-07-09 lh provided under this License. Any attempt otherwise to propagate or
411 4347b5b9 2021-07-09 lh modify it is void, and will automatically terminate your rights under
412 4347b5b9 2021-07-09 lh this License (including any patent licenses granted under the third
413 4347b5b9 2021-07-09 lh paragraph of section 11).
415 4347b5b9 2021-07-09 lh However, if you cease all violation of this License, then your
416 4347b5b9 2021-07-09 lh license from a particular copyright holder is reinstated (a)
417 4347b5b9 2021-07-09 lh provisionally, unless and until the copyright holder explicitly and
418 4347b5b9 2021-07-09 lh finally terminates your license, and (b) permanently, if the copyright
419 4347b5b9 2021-07-09 lh holder fails to notify you of the violation by some reasonable means
420 4347b5b9 2021-07-09 lh prior to 60 days after the cessation.
422 4347b5b9 2021-07-09 lh Moreover, your license from a particular copyright holder is
423 4347b5b9 2021-07-09 lh reinstated permanently if the copyright holder notifies you of the
424 4347b5b9 2021-07-09 lh violation by some reasonable means, this is the first time you have
425 4347b5b9 2021-07-09 lh received notice of violation of this License (for any work) from that
426 4347b5b9 2021-07-09 lh copyright holder, and you cure the violation prior to 30 days after
427 4347b5b9 2021-07-09 lh your receipt of the notice.
429 4347b5b9 2021-07-09 lh Termination of your rights under this section does not terminate the
430 4347b5b9 2021-07-09 lh licenses of parties who have received copies or rights from you under
431 4347b5b9 2021-07-09 lh this License. If your rights have been terminated and not permanently
432 4347b5b9 2021-07-09 lh reinstated, you do not qualify to receive new licenses for the same
433 4347b5b9 2021-07-09 lh material under section 10.
435 4347b5b9 2021-07-09 lh 9. Acceptance Not Required for Having Copies.
437 4347b5b9 2021-07-09 lh You are not required to accept this License in order to receive or
438 4347b5b9 2021-07-09 lh run a copy of the Program. Ancillary propagation of a covered work
439 4347b5b9 2021-07-09 lh occurring solely as a consequence of using peer-to-peer transmission
440 4347b5b9 2021-07-09 lh to receive a copy likewise does not require acceptance. However,
441 4347b5b9 2021-07-09 lh nothing other than this License grants you permission to propagate or
442 4347b5b9 2021-07-09 lh modify any covered work. These actions infringe copyright if you do
443 4347b5b9 2021-07-09 lh not accept this License. Therefore, by modifying or propagating a
444 4347b5b9 2021-07-09 lh covered work, you indicate your acceptance of this License to do so.
446 4347b5b9 2021-07-09 lh 10. Automatic Licensing of Downstream Recipients.
448 4347b5b9 2021-07-09 lh Each time you convey a covered work, the recipient automatically
449 4347b5b9 2021-07-09 lh receives a license from the original licensors, to run, modify and
450 4347b5b9 2021-07-09 lh propagate that work, subject to this License. You are not responsible
451 4347b5b9 2021-07-09 lh for enforcing compliance by third parties with this License.
453 4347b5b9 2021-07-09 lh An "entity transaction" is a transaction transferring control of an
454 4347b5b9 2021-07-09 lh organization, or substantially all assets of one, or subdividing an
455 4347b5b9 2021-07-09 lh organization, or merging organizations. If propagation of a covered
456 4347b5b9 2021-07-09 lh work results from an entity transaction, each party to that
457 4347b5b9 2021-07-09 lh transaction who receives a copy of the work also receives whatever
458 4347b5b9 2021-07-09 lh licenses to the work the party's predecessor in interest had or could
459 4347b5b9 2021-07-09 lh give under the previous paragraph, plus a right to possession of the
460 4347b5b9 2021-07-09 lh Corresponding Source of the work from the predecessor in interest, if
461 4347b5b9 2021-07-09 lh the predecessor has it or can get it with reasonable efforts.
463 4347b5b9 2021-07-09 lh You may not impose any further restrictions on the exercise of the
464 4347b5b9 2021-07-09 lh rights granted or affirmed under this License. For example, you may
465 4347b5b9 2021-07-09 lh not impose a license fee, royalty, or other charge for exercise of
466 4347b5b9 2021-07-09 lh rights granted under this License, and you may not initiate litigation
467 4347b5b9 2021-07-09 lh (including a cross-claim or counterclaim in a lawsuit) alleging that
468 4347b5b9 2021-07-09 lh any patent claim is infringed by making, using, selling, offering for
469 4347b5b9 2021-07-09 lh sale, or importing the Program or any portion of it.
473 4347b5b9 2021-07-09 lh A "contributor" is a copyright holder who authorizes use under this
474 4347b5b9 2021-07-09 lh License of the Program or a work on which the Program is based. The
475 4347b5b9 2021-07-09 lh work thus licensed is called the contributor's "contributor version".
477 4347b5b9 2021-07-09 lh A contributor's "essential patent claims" are all patent claims
478 4347b5b9 2021-07-09 lh owned or controlled by the contributor, whether already acquired or
479 4347b5b9 2021-07-09 lh hereafter acquired, that would be infringed by some manner, permitted
480 4347b5b9 2021-07-09 lh by this License, of making, using, or selling its contributor version,
481 4347b5b9 2021-07-09 lh but do not include claims that would be infringed only as a
482 4347b5b9 2021-07-09 lh consequence of further modification of the contributor version. For
483 4347b5b9 2021-07-09 lh purposes of this definition, "control" includes the right to grant
484 4347b5b9 2021-07-09 lh patent sublicenses in a manner consistent with the requirements of
485 4347b5b9 2021-07-09 lh this License.
487 4347b5b9 2021-07-09 lh Each contributor grants you a non-exclusive, worldwide, royalty-free
488 4347b5b9 2021-07-09 lh patent license under the contributor's essential patent claims, to
489 4347b5b9 2021-07-09 lh make, use, sell, offer for sale, import and otherwise run, modify and
490 4347b5b9 2021-07-09 lh propagate the contents of its contributor version.
492 4347b5b9 2021-07-09 lh In the following three paragraphs, a "patent license" is any express
493 4347b5b9 2021-07-09 lh agreement or commitment, however denominated, not to enforce a patent
494 4347b5b9 2021-07-09 lh (such as an express permission to practice a patent or covenant not to
495 4347b5b9 2021-07-09 lh sue for patent infringement). To "grant" such a patent license to a
496 4347b5b9 2021-07-09 lh party means to make such an agreement or commitment not to enforce a
497 4347b5b9 2021-07-09 lh patent against the party.
499 4347b5b9 2021-07-09 lh If you convey a covered work, knowingly relying on a patent license,
500 4347b5b9 2021-07-09 lh and the Corresponding Source of the work is not available for anyone
501 4347b5b9 2021-07-09 lh to copy, free of charge and under the terms of this License, through a
502 4347b5b9 2021-07-09 lh publicly available network server or other readily accessible means,
503 4347b5b9 2021-07-09 lh then you must either (1) cause the Corresponding Source to be so
504 4347b5b9 2021-07-09 lh available, or (2) arrange to deprive yourself of the benefit of the
505 4347b5b9 2021-07-09 lh patent license for this particular work, or (3) arrange, in a manner
506 4347b5b9 2021-07-09 lh consistent with the requirements of this License, to extend the patent
507 4347b5b9 2021-07-09 lh license to downstream recipients. "Knowingly relying" means you have
508 4347b5b9 2021-07-09 lh actual knowledge that, but for the patent license, your conveying the
509 4347b5b9 2021-07-09 lh covered work in a country, or your recipient's use of the covered work
510 4347b5b9 2021-07-09 lh in a country, would infringe one or more identifiable patents in that
511 4347b5b9 2021-07-09 lh country that you have reason to believe are valid.
513 4347b5b9 2021-07-09 lh If, pursuant to or in connection with a single transaction or
514 4347b5b9 2021-07-09 lh arrangement, you convey, or propagate by procuring conveyance of, a
515 4347b5b9 2021-07-09 lh covered work, and grant a patent license to some of the parties
516 4347b5b9 2021-07-09 lh receiving the covered work authorizing them to use, propagate, modify
517 4347b5b9 2021-07-09 lh or convey a specific copy of the covered work, then the patent license
518 4347b5b9 2021-07-09 lh you grant is automatically extended to all recipients of the covered
519 4347b5b9 2021-07-09 lh work and works based on it.
521 4347b5b9 2021-07-09 lh A patent license is "discriminatory" if it does not include within
522 4347b5b9 2021-07-09 lh the scope of its coverage, prohibits the exercise of, or is
523 4347b5b9 2021-07-09 lh conditioned on the non-exercise of one or more of the rights that are
524 4347b5b9 2021-07-09 lh specifically granted under this License. You may not convey a covered
525 4347b5b9 2021-07-09 lh work if you are a party to an arrangement with a third party that is
526 4347b5b9 2021-07-09 lh in the business of distributing software, under which you make payment
527 4347b5b9 2021-07-09 lh to the third party based on the extent of your activity of conveying
528 4347b5b9 2021-07-09 lh the work, and under which the third party grants, to any of the
529 4347b5b9 2021-07-09 lh parties who would receive the covered work from you, a discriminatory
530 4347b5b9 2021-07-09 lh patent license (a) in connection with copies of the covered work
531 4347b5b9 2021-07-09 lh conveyed by you (or copies made from those copies), or (b) primarily
532 4347b5b9 2021-07-09 lh for and in connection with specific products or compilations that
533 4347b5b9 2021-07-09 lh contain the covered work, unless you entered into that arrangement,
534 4347b5b9 2021-07-09 lh or that patent license was granted, prior to 28 March 2007.
536 4347b5b9 2021-07-09 lh Nothing in this License shall be construed as excluding or limiting
537 4347b5b9 2021-07-09 lh any implied license or other defenses to infringement that may
538 4347b5b9 2021-07-09 lh otherwise be available to you under applicable patent law.
540 4347b5b9 2021-07-09 lh 12. No Surrender of Others' Freedom.
542 4347b5b9 2021-07-09 lh If conditions are imposed on you (whether by court order, agreement or
543 4347b5b9 2021-07-09 lh otherwise) that contradict the conditions of this License, they do not
544 4347b5b9 2021-07-09 lh excuse you from the conditions of this License. If you cannot convey a
545 4347b5b9 2021-07-09 lh covered work so as to satisfy simultaneously your obligations under this
546 4347b5b9 2021-07-09 lh License and any other pertinent obligations, then as a consequence you may
547 4347b5b9 2021-07-09 lh not convey it at all. For example, if you agree to terms that obligate you
548 4347b5b9 2021-07-09 lh to collect a royalty for further conveying from those to whom you convey
549 4347b5b9 2021-07-09 lh the Program, the only way you could satisfy both those terms and this
550 4347b5b9 2021-07-09 lh License would be to refrain entirely from conveying the Program.
552 4347b5b9 2021-07-09 lh 13. Use with the GNU Affero General Public License.
554 4347b5b9 2021-07-09 lh Notwithstanding any other provision of this License, you have
555 4347b5b9 2021-07-09 lh permission to link or combine any covered work with a work licensed
556 4347b5b9 2021-07-09 lh under version 3 of the GNU Affero General Public License into a single
557 4347b5b9 2021-07-09 lh combined work, and to convey the resulting work. The terms of this
558 4347b5b9 2021-07-09 lh License will continue to apply to the part which is the covered work,
559 4347b5b9 2021-07-09 lh but the special requirements of the GNU Affero General Public License,
560 4347b5b9 2021-07-09 lh section 13, concerning interaction through a network will apply to the
561 4347b5b9 2021-07-09 lh combination as such.
563 4347b5b9 2021-07-09 lh 14. Revised Versions of this License.
565 4347b5b9 2021-07-09 lh The Free Software Foundation may publish revised and/or new versions of
566 4347b5b9 2021-07-09 lh the GNU General Public License from time to time. Such new versions will
567 4347b5b9 2021-07-09 lh be similar in spirit to the present version, but may differ in detail to
568 4347b5b9 2021-07-09 lh address new problems or concerns.
570 4347b5b9 2021-07-09 lh Each version is given a distinguishing version number. If the
571 4347b5b9 2021-07-09 lh Program specifies that a certain numbered version of the GNU General
572 4347b5b9 2021-07-09 lh Public License "or any later version" applies to it, you have the
573 4347b5b9 2021-07-09 lh option of following the terms and conditions either of that numbered
574 4347b5b9 2021-07-09 lh version or of any later version published by the Free Software
575 4347b5b9 2021-07-09 lh Foundation. If the Program does not specify a version number of the
576 4347b5b9 2021-07-09 lh GNU General Public License, you may choose any version ever published
577 4347b5b9 2021-07-09 lh by the Free Software Foundation.
579 4347b5b9 2021-07-09 lh If the Program specifies that a proxy can decide which future
580 4347b5b9 2021-07-09 lh versions of the GNU General Public License can be used, that proxy's
581 4347b5b9 2021-07-09 lh public statement of acceptance of a version permanently authorizes you
582 4347b5b9 2021-07-09 lh to choose that version for the Program.
584 4347b5b9 2021-07-09 lh Later license versions may give you additional or different
585 4347b5b9 2021-07-09 lh permissions. However, no additional obligations are imposed on any
586 4347b5b9 2021-07-09 lh author or copyright holder as a result of your choosing to follow a
587 4347b5b9 2021-07-09 lh later version.
589 4347b5b9 2021-07-09 lh 15. Disclaimer of Warranty.
591 4347b5b9 2021-07-09 lh THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
592 4347b5b9 2021-07-09 lh APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
593 4347b5b9 2021-07-09 lh HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
594 4347b5b9 2021-07-09 lh OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
595 4347b5b9 2021-07-09 lh THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
596 4347b5b9 2021-07-09 lh PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
597 4347b5b9 2021-07-09 lh IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
598 4347b5b9 2021-07-09 lh ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
600 4347b5b9 2021-07-09 lh 16. Limitation of Liability.
602 4347b5b9 2021-07-09 lh IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
603 4347b5b9 2021-07-09 lh WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
604 4347b5b9 2021-07-09 lh THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
605 4347b5b9 2021-07-09 lh GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
606 4347b5b9 2021-07-09 lh USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
607 4347b5b9 2021-07-09 lh DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
608 4347b5b9 2021-07-09 lh PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
609 4347b5b9 2021-07-09 lh EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
610 4347b5b9 2021-07-09 lh SUCH DAMAGES.
612 4347b5b9 2021-07-09 lh 17. Interpretation of Sections 15 and 16.
614 4347b5b9 2021-07-09 lh If the disclaimer of warranty and limitation of liability provided
615 4347b5b9 2021-07-09 lh above cannot be given local legal effect according to their terms,
616 4347b5b9 2021-07-09 lh reviewing courts shall apply local law that most closely approximates
617 4347b5b9 2021-07-09 lh an absolute waiver of all civil liability in connection with the
618 4347b5b9 2021-07-09 lh Program, unless a warranty or assumption of liability accompanies a
619 4347b5b9 2021-07-09 lh copy of the Program in return for a fee.
621 4347b5b9 2021-07-09 lh END OF TERMS AND CONDITIONS
623 4347b5b9 2021-07-09 lh How to Apply These Terms to Your New Programs
625 4347b5b9 2021-07-09 lh If you develop a new program, and you want it to be of the greatest
626 4347b5b9 2021-07-09 lh possible use to the public, the best way to achieve this is to make it
627 4347b5b9 2021-07-09 lh free software which everyone can redistribute and change under these terms.
629 4347b5b9 2021-07-09 lh To do so, attach the following notices to the program. It is safest
630 4347b5b9 2021-07-09 lh to attach them to the start of each source file to most effectively
631 4347b5b9 2021-07-09 lh state the exclusion of warranty; and each file should have at least
632 4347b5b9 2021-07-09 lh the "copyright" line and a pointer to where the full notice is found.
634 4347b5b9 2021-07-09 lh <one line to give the program's name and a brief idea of what it does.>
635 4347b5b9 2021-07-09 lh Copyright (C) <year> <name of author>
637 4347b5b9 2021-07-09 lh This program is free software: you can redistribute it and/or modify
638 4347b5b9 2021-07-09 lh it under the terms of the GNU General Public License as published by
639 4347b5b9 2021-07-09 lh the Free Software Foundation, either version 3 of the License, or
640 4347b5b9 2021-07-09 lh (at your option) any later version.
642 4347b5b9 2021-07-09 lh This program is distributed in the hope that it will be useful,
643 4347b5b9 2021-07-09 lh but WITHOUT ANY WARRANTY; without even the implied warranty of
644 4347b5b9 2021-07-09 lh MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
645 4347b5b9 2021-07-09 lh GNU General Public License for more details.
647 4347b5b9 2021-07-09 lh You should have received a copy of the GNU General Public License
648 4347b5b9 2021-07-09 lh along with this program. If not, see <https://www.gnu.org/licenses/>.
650 4347b5b9 2021-07-09 lh Also add information on how to contact you by electronic and paper mail.
652 4347b5b9 2021-07-09 lh If the program does terminal interaction, make it output a short
653 4347b5b9 2021-07-09 lh notice like this when it starts in an interactive mode:
655 4347b5b9 2021-07-09 lh <program> Copyright (C) <year> <name of author>
656 4347b5b9 2021-07-09 lh This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
657 4347b5b9 2021-07-09 lh This is free software, and you are welcome to redistribute it
658 4347b5b9 2021-07-09 lh under certain conditions; type `show c' for details.
660 4347b5b9 2021-07-09 lh The hypothetical commands `show w' and `show c' should show the appropriate
661 4347b5b9 2021-07-09 lh parts of the General Public License. Of course, your program's commands
662 4347b5b9 2021-07-09 lh might be different; for a GUI interface, you would use an "about box".
664 4347b5b9 2021-07-09 lh You should also get your employer (if you work as a programmer) or school,
665 4347b5b9 2021-07-09 lh if any, to sign a "copyright disclaimer" for the program, if necessary.

671 4347b5b9 2021-07-09 lh may consider it more useful to permit linking proprietary applications with
