| | 4 | + | Version 3, 29 June 2007 |
| | 5 | + | |
| | 6 | + | Copyright © 2007 Free Software Foundation, Inc. <<https://www.fsf.org/>> |
| | 7 | + | |
| | 8 | + | Everyone is permitted to copy and distribute verbatim copies of this license |
| | 9 | + | document, but changing it is not allowed. |
| | 10 | + | |
| | 11 | + | ## Preamble |
| | 12 | + | |
| | 13 | + | The GNU General Public License is a free, copyleft license for software and other |
| | 14 | + | kinds of works. |
| | 15 | + | |
| | 16 | + | The licenses for most software and other practical works are designed to take away |
| | 17 | + | your freedom to share and change the works. By contrast, the GNU General Public |
| | 18 | + | License is intended to guarantee your freedom to share and change all versions of a |
| | 19 | + | program--to make sure it remains free software for all its users. We, the Free |
| | 20 | + | Software Foundation, use the GNU General Public License for most of our software; it |
| | 21 | + | applies also to any other work released this way by its authors. You can apply it to |
| | 22 | + | your programs, too. |
| | 23 | + | |
| | 24 | + | When we speak of free software, we are referring to freedom, not price. Our General |
| | 25 | + | Public Licenses are designed to make sure that you have the freedom to distribute |
| | 26 | + | copies of free software (and charge for them if you wish), that you receive source |
| | 27 | + | code or can get it if you want it, that you can change the software or use pieces of |
| | 28 | + | it in new free programs, and that you know you can do these things. |
| | 29 | + | |
| | 30 | + | To protect your rights, we need to prevent others from denying you these rights or |
| | 31 | + | asking you to surrender the rights. Therefore, you have certain responsibilities if |
| | 32 | + | you distribute copies of the software, or if you modify it: responsibilities to |
| | 33 | + | respect the freedom of others. |
| | 34 | + | |
| | 35 | + | For example, if you distribute copies of such a program, whether gratis or for a fee, |
| | 36 | + | you must pass on to the recipients the same freedoms that you received. You must make |
| | 37 | + | sure that they, too, receive or can get the source code. And you must show them these |
| | 38 | + | terms so they know their rights. |
| | 39 | + | |
| | 40 | + | Developers that use the GNU GPL protect your rights with two steps: (1) assert |
| | 41 | + | copyright on the software, and (2) offer you this License giving you legal permission |
| | 42 | + | to copy, distribute and/or modify it. |
| | 43 | + | |
| | 44 | + | For the developers' and authors' protection, the GPL clearly explains that there is |
| | 45 | + | no warranty for this free software. For both users' and authors' sake, the GPL |
| | 46 | + | requires that modified versions be marked as changed, so that their problems will not |
| | 47 | + | be attributed erroneously to authors of previous versions. |
| | 48 | + | |
| | 49 | + | Some devices are designed to deny users access to install or run modified versions of |
| | 50 | + | the software inside them, although the manufacturer can do so. This is fundamentally |
| | 51 | + | incompatible with the aim of protecting users' freedom to change the software. The |
| | 52 | + | systematic pattern of such abuse occurs in the area of products for individuals to |
| | 53 | + | use, which is precisely where it is most unacceptable. Therefore, we have designed |
| | 54 | + | this version of the GPL to prohibit the practice for those products. If such problems |
| | 55 | + | arise substantially in other domains, we stand ready to extend this provision to |
| | 56 | + | those domains in future versions of the GPL, as needed to protect the freedom of |
| | 57 | + | users. |
| | 58 | + | |
| | 59 | + | Finally, every program is threatened constantly by software patents. States should |
| | 60 | + | not allow patents to restrict development and use of software on general-purpose |
| | 61 | + | computers, but in those that do, we wish to avoid the special danger that patents |
| | 62 | + | applied to a free program could make it effectively proprietary. To prevent this, the |
| | 63 | + | GPL assures that patents cannot be used to render the program non-free. |
| | 64 | + | |
| | 65 | + | The precise terms and conditions for copying, distribution and modification follow. |
| | 66 | + | |
| | 67 | + | ## TERMS AND CONDITIONS |
| | 68 | + | |
| | 69 | + | ### 0. Definitions. |
| | 70 | + | |
| | 71 | + | “This License” refers to version 3 of the GNU General Public License. |
| | 72 | + | |
| | 73 | + | “Copyright” also means copyright-like laws that apply to other kinds of |
| | 74 | + | works, such as semiconductor masks. |
| | 75 | + | |
| | 76 | + | “The Program” refers to any copyrightable work licensed under this |
| | 77 | + | License. Each licensee is addressed as “you”. “Licensees” and |
| | 78 | + | “recipients” may be individuals or organizations. |
| | 79 | + | |
| | 80 | + | To “modify” a work means to copy from or adapt all or part of the work in |
| | 81 | + | a fashion requiring copyright permission, other than the making of an exact copy. The |
| | 82 | + | resulting work is called a “modified version” of the earlier work or a |
| | 83 | + | work “based on” the earlier work. |
| | 84 | + | |
| | 85 | + | A “covered work” means either the unmodified Program or a work based on |
| | 86 | + | the Program. |
| | 87 | + | |
| | 88 | + | To “propagate” a work means to do anything with it that, without |
| | 89 | + | permission, would make you directly or secondarily liable for infringement under |
| | 90 | + | applicable copyright law, except executing it on a computer or modifying a private |
| | 91 | + | copy. Propagation includes copying, distribution (with or without modification), |
| | 92 | + | making available to the public, and in some countries other activities as well. |
| | 93 | + | |
| | 94 | + | To “convey” a work means any kind of propagation that enables other |
| | 95 | + | parties to make or receive copies. Mere interaction with a user through a computer |
| | 96 | + | network, with no transfer of a copy, is not conveying. |
| | 97 | + | |
| | 98 | + | An interactive user interface displays “Appropriate Legal Notices” to the |
| | 99 | + | extent that it includes a convenient and prominently visible feature that (1) |
| | 100 | + | displays an appropriate copyright notice, and (2) tells the user that there is no |
| | 101 | + | warranty for the work (except to the extent that warranties are provided), that |
| | 102 | + | licensees may convey the work under this License, and how to view a copy of this |
| | 103 | + | License. If the interface presents a list of user commands or options, such as a |
| | 104 | + | menu, a prominent item in the list meets this criterion. |
| | 105 | + | |
| | 106 | + | ### 1. Source Code. |
| | 107 | + | |
| | 108 | + | The “source code” for a work means the preferred form of the work for |
| | 109 | + | making modifications to it. “Object code” means any non-source form of a |
| | 110 | + | work. |
| | 111 | + | |
| | 112 | + | A “Standard Interface” means an interface that either is an official |
| | 113 | + | standard defined by a recognized standards body, or, in the case of interfaces |
| | 114 | + | specified for a particular programming language, one that is widely used among |
| | 115 | + | developers working in that language. |
| | 116 | + | |
| | 117 | + | The “System Libraries” of an executable work include anything, other than |
| | 118 | + | the work as a whole, that (a) is included in the normal form of packaging a Major |
| | 119 | + | Component, but which is not part of that Major Component, and (b) serves only to |
| | 120 | + | enable use of the work with that Major Component, or to implement a Standard |
| | 121 | + | Interface for which an implementation is available to the public in source code form. |
| | 122 | + | A “Major Component”, in this context, means a major essential component |
| | 123 | + | (kernel, window system, and so on) of the specific operating system (if any) on which |
| | 124 | + | the executable work runs, or a compiler used to produce the work, or an object code |
| | 125 | + | interpreter used to run it. |
| | 126 | + | |
| | 127 | + | The “Corresponding Source” for a work in object code form means all the |
| | 128 | + | source code needed to generate, install, and (for an executable work) run the object |
| | 129 | + | code and to modify the work, including scripts to control those activities. However, |
| | 130 | + | it does not include the work's System Libraries, or general-purpose tools or |
| | 131 | + | generally available free programs which are used unmodified in performing those |
| | 132 | + | activities but which are not part of the work. For example, Corresponding Source |
| | 133 | + | includes interface definition files associated with source files for the work, and |
| | 134 | + | the source code for shared libraries and dynamically linked subprograms that the work |
| | 135 | + | is specifically designed to require, such as by intimate data communication or |
| | 136 | + | control flow between those subprograms and other parts of the work. |
| | 137 | + | |
| | 138 | + | The Corresponding Source need not include anything that users can regenerate |
| | 139 | + | automatically from other parts of the Corresponding Source. |
| | 140 | + | |
| | 141 | + | The Corresponding Source for a work in source code form is that same work. |
| | 142 | + | |
| | 143 | + | ### 2. Basic Permissions. |
| | 144 | + | |
| | 145 | + | All rights granted under this License are granted for the term of copyright on the |
| | 146 | + | Program, and are irrevocable provided the stated conditions are met. This License |
| | 147 | + | explicitly affirms your unlimited permission to run the unmodified Program. The |
| | 148 | + | output from running a covered work is covered by this License only if the output, |
| | 149 | + | given its content, constitutes a covered work. This License acknowledges your rights |
| | 150 | + | of fair use or other equivalent, as provided by copyright law. |
| | 151 | + | |
| | 152 | + | You may make, run and propagate covered works that you do not convey, without |
| | 153 | + | conditions so long as your license otherwise remains in force. You may convey covered |
| | 154 | + | works to others for the sole purpose of having them make modifications exclusively |
| | 155 | + | for you, or provide you with facilities for running those works, provided that you |
| | 156 | + | comply with the terms of this License in conveying all material for which you do not |
| | 157 | + | control copyright. Those thus making or running the covered works for you must do so |
| | 158 | + | exclusively on your behalf, under your direction and control, on terms that prohibit |
| | 159 | + | them from making any copies of your copyrighted material outside their relationship |
| | 160 | + | with you. |
| | 161 | + | |
| | 162 | + | Conveying under any other circumstances is permitted solely under the conditions |
| | 163 | + | stated below. Sublicensing is not allowed; section 10 makes it unnecessary. |
| | 164 | + | |
| | 165 | + | ### 3. Protecting Users' Legal Rights From Anti-Circumvention Law. |
| | 166 | + | |
| | 167 | + | No covered work shall be deemed part of an effective technological measure under any |
| | 168 | + | applicable law fulfilling obligations under article 11 of the WIPO copyright treaty |
| | 169 | + | adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention |
| | 170 | + | of such measures. |
| | 171 | + | |
| | 172 | + | When you convey a covered work, you waive any legal power to forbid circumvention of |
| | 173 | + | technological measures to the extent such circumvention is effected by exercising |
| | 174 | + | rights under this License with respect to the covered work, and you disclaim any |
| | 175 | + | intention to limit operation or modification of the work as a means of enforcing, |
| | 176 | + | against the work's users, your or third parties' legal rights to forbid circumvention |
| | 177 | + | of technological measures. |
| | 178 | + | |
| | 179 | + | ### 4. Conveying Verbatim Copies. |
| | 180 | + | |
| | 181 | + | You may convey verbatim copies of the Program's source code as you receive it, in any |
| | 182 | + | medium, provided that you conspicuously and appropriately publish on each copy an |
| | 183 | + | appropriate copyright notice; keep intact all notices stating that this License and |
| | 184 | + | any non-permissive terms added in accord with section 7 apply to the code; keep |
| | 185 | + | intact all notices of the absence of any warranty; and give all recipients a copy of |
| | 186 | + | this License along with the Program. |
| | 187 | + | |
| | 188 | + | You may charge any price or no price for each copy that you convey, and you may offer |
| | 189 | + | support or warranty protection for a fee. |
| | 190 | + | |
| | 191 | + | ### 5. Conveying Modified Source Versions. |
| | 192 | + | |
| | 193 | + | You may convey a work based on the Program, or the modifications to produce it from |
| | 194 | + | the Program, in the form of source code under the terms of section 4, provided that |
| | 195 | + | you also meet all of these conditions: |
| | 196 | + | |
| | 197 | + | * **a)** The work must carry prominent notices stating that you modified it, and giving a |
| | 198 | + | relevant date. |
| | 199 | + | * **b)** The work must carry prominent notices stating that it is released under this |
| | 200 | + | License and any conditions added under section 7. This requirement modifies the |
| | 201 | + | requirement in section 4 to “keep intact all notices”. |
| | 202 | + | * **c)** You must license the entire work, as a whole, under this License to anyone who |
| | 203 | + | comes into possession of a copy. This License will therefore apply, along with any |
| | 204 | + | applicable section 7 additional terms, to the whole of the work, and all its parts, |
| | 205 | + | regardless of how they are packaged. This License gives no permission to license the |
| | 206 | + | work in any other way, but it does not invalidate such permission if you have |
| | 207 | + | separately received it. |
| | 208 | + | * **d)** If the work has interactive user interfaces, each must display Appropriate Legal |
| | 209 | + | Notices; however, if the Program has interactive interfaces that do not display |
| | 210 | + | Appropriate Legal Notices, your work need not make them do so. |
| | 211 | + | |
| | 212 | + | A compilation of a covered work with other separate and independent works, which are |
| | 213 | + | not by their nature extensions of the covered work, and which are not combined with |
| | 214 | + | it such as to form a larger program, in or on a volume of a storage or distribution |
| | 215 | + | medium, is called an “aggregate” if the compilation and its resulting |
| | 216 | + | copyright are not used to limit the access or legal rights of the compilation's users |
| | 217 | + | beyond what the individual works permit. Inclusion of a covered work in an aggregate |
| | 218 | + | does not cause this License to apply to the other parts of the aggregate. |
| | 219 | + | |
| | 220 | + | ### 6. Conveying Non-Source Forms. |
| | 221 | + | |
| | 222 | + | You may convey a covered work in object code form under the terms of sections 4 and |
| | 223 | + | 5, provided that you also convey the machine-readable Corresponding Source under the |
| | 224 | + | terms of this License, in one of these ways: |
| | 225 | + | |
| | 226 | + | * **a)** Convey the object code in, or embodied in, a physical product (including a |
| | 227 | + | physical distribution medium), accompanied by the Corresponding Source fixed on a |
| | 228 | + | durable physical medium customarily used for software interchange. |
| | 229 | + | * **b)** Convey the object code in, or embodied in, a physical product (including a |
| | 230 | + | physical distribution medium), accompanied by a written offer, valid for at least |
| | 231 | + | three years and valid for as long as you offer spare parts or customer support for |
| | 232 | + | that product model, to give anyone who possesses the object code either (1) a copy of |
| | 233 | + | the Corresponding Source for all the software in the product that is covered by this |
| | 234 | + | License, on a durable physical medium customarily used for software interchange, for |
| | 235 | + | a price no more than your reasonable cost of physically performing this conveying of |
| | 236 | + | source, or (2) access to copy the Corresponding Source from a network server at no |
| | 237 | + | charge. |
| | 238 | + | * **c)** Convey individual copies of the object code with a copy of the written offer to |
| | 239 | + | provide the Corresponding Source. This alternative is allowed only occasionally and |
| | 240 | + | noncommercially, and only if you received the object code with such an offer, in |
| | 241 | + | accord with subsection 6b. |
| | 242 | + | * **d)** Convey the object code by offering access from a designated place (gratis or for |
| | 243 | + | a charge), and offer equivalent access to the Corresponding Source in the same way |
| | 244 | + | through the same place at no further charge. You need not require recipients to copy |
| | 245 | + | the Corresponding Source along with the object code. If the place to copy the object |
| | 246 | + | code is a network server, the Corresponding Source may be on a different server |
| | 247 | + | (operated by you or a third party) that supports equivalent copying facilities, |
| | 248 | + | provided you maintain clear directions next to the object code saying where to find |
| | 249 | + | the Corresponding Source. Regardless of what server hosts the Corresponding Source, |
| | 250 | + | you remain obligated to ensure that it is available for as long as needed to satisfy |
| | 251 | + | these requirements. |
| | 252 | + | * **e)** Convey the object code using peer-to-peer transmission, provided you inform |
| | 253 | + | other peers where the object code and Corresponding Source of the work are being |
| | 254 | + | offered to the general public at no charge under subsection 6d. |
| | 255 | + | |
| | 256 | + | A separable portion of the object code, whose source code is excluded from the |
| | 257 | + | Corresponding Source as a System Library, need not be included in conveying the |
| | 258 | + | object code work. |
| | 259 | + | |
| | 260 | + | A “User Product” is either (1) a “consumer product”, which |
| | 261 | + | means any tangible personal property which is normally used for personal, family, or |
| | 262 | + | household purposes, or (2) anything designed or sold for incorporation into a |
| | 263 | + | dwelling. In determining whether a product is a consumer product, doubtful cases |
| | 264 | + | shall be resolved in favor of coverage. For a particular product received by a |
| | 265 | + | particular user, “normally used” refers to a typical or common use of |
| | 266 | + | that class of product, regardless of the status of the particular user or of the way |
| | 267 | + | in which the particular user actually uses, or expects or is expected to use, the |
| | 268 | + | product. A product is a consumer product regardless of whether the product has |
| | 269 | + | substantial commercial, industrial or non-consumer uses, unless such uses represent |
| | 270 | + | the only significant mode of use of the product. |
| | 271 | + | |
| | 272 | + | “Installation Information” for a User Product means any methods, |
| | 273 | + | procedures, authorization keys, or other information required to install and execute |
| | 274 | + | modified versions of a covered work in that User Product from a modified version of |
| | 275 | + | its Corresponding Source. The information must suffice to ensure that the continued |
| | 276 | + | functioning of the modified object code is in no case prevented or interfered with |
| | 277 | + | solely because modification has been made. |
| | 278 | + | |
| | 279 | + | If you convey an object code work under this section in, or with, or specifically for |
| | 280 | + | use in, a User Product, and the conveying occurs as part of a transaction in which |
| | 281 | + | the right of possession and use of the User Product is transferred to the recipient |
| | 282 | + | in perpetuity or for a fixed term (regardless of how the transaction is |
| | 283 | + | characterized), the Corresponding Source conveyed under this section must be |
| | 284 | + | accompanied by the Installation Information. But this requirement does not apply if |
| | 285 | + | neither you nor any third party retains the ability to install modified object code |
| | 286 | + | on the User Product (for example, the work has been installed in ROM). |
| | 287 | + | |
| | 288 | + | The requirement to provide Installation Information does not include a requirement to |
| | 289 | + | continue to provide support service, warranty, or updates for a work that has been |
| | 290 | + | modified or installed by the recipient, or for the User Product in which it has been |
| | 291 | + | modified or installed. Access to a network may be denied when the modification itself |
| | 292 | + | materially and adversely affects the operation of the network or violates the rules |
| | 293 | + | and protocols for communication across the network. |
| | 294 | + | |
| | 295 | + | Corresponding Source conveyed, and Installation Information provided, in accord with |
| | 296 | + | this section must be in a format that is publicly documented (and with an |
| | 297 | + | implementation available to the public in source code form), and must require no |
| | 298 | + | special password or key for unpacking, reading or copying. |
| | 299 | + | |
| | 300 | + | ### 7. Additional Terms. |
| | 301 | + | |
| | 302 | + | “Additional permissions” are terms that supplement the terms of this |
| | 303 | + | License by making exceptions from one or more of its conditions. Additional |
| | 304 | + | permissions that are applicable to the entire Program shall be treated as though they |
| | 305 | + | were included in this License, to the extent that they are valid under applicable |
| | 306 | + | law. If additional permissions apply only to part of the Program, that part may be |
| | 307 | + | used separately under those permissions, but the entire Program remains governed by |
| | 308 | + | this License without regard to the additional permissions. |
| | 309 | + | |
| | 310 | + | When you convey a copy of a covered work, you may at your option remove any |
| | 311 | + | additional permissions from that copy, or from any part of it. (Additional |
| | 312 | + | permissions may be written to require their own removal in certain cases when you |
| | 313 | + | modify the work.) You may place additional permissions on material, added by you to a |
| | 314 | + | covered work, for which you have or can give appropriate copyright permission. |
| | 315 | + | |
| | 316 | + | Notwithstanding any other provision of this License, for material you add to a |
| | 317 | + | covered work, you may (if authorized by the copyright holders of that material) |
| | 318 | + | supplement the terms of this License with terms: |
| | 319 | + | |
| | 320 | + | * **a)** Disclaiming warranty or limiting liability differently from the terms of |
| | 321 | + | sections 15 and 16 of this License; or |
| | 322 | + | * **b)** Requiring preservation of specified reasonable legal notices or author |
| | 323 | + | attributions in that material or in the Appropriate Legal Notices displayed by works |
| | 324 | + | containing it; or |
| | 325 | + | * **c)** Prohibiting misrepresentation of the origin of that material, or requiring that |
| | 326 | + | modified versions of such material be marked in reasonable ways as different from the |
| | 327 | + | original version; or |
| | 328 | + | * **d)** Limiting the use for publicity purposes of names of licensors or authors of the |
| | 329 | + | material; or |
| | 330 | + | * **e)** Declining to grant rights under trademark law for use of some trade names, |
| | 331 | + | trademarks, or service marks; or |
| | 332 | + | * **f)** Requiring indemnification of licensors and authors of that material by anyone |
| | 333 | + | who conveys the material (or modified versions of it) with contractual assumptions of |
| | 334 | + | liability to the recipient, for any liability that these contractual assumptions |
| | 335 | + | directly impose on those licensors and authors. |
| | 336 | + | |
| | 337 | + | All other non-permissive additional terms are considered “further |
| | 338 | + | restrictions” within the meaning of section 10. If the Program as you received |
| | 339 | + | it, or any part of it, contains a notice stating that it is governed by this License |
| | 340 | + | along with a term that is a further restriction, you may remove that term. If a |
| | 341 | + | license document contains a further restriction but permits relicensing or conveying |
| | 342 | + | under this License, you may add to a covered work material governed by the terms of |
| | 343 | + | that license document, provided that the further restriction does not survive such |
| | 344 | + | relicensing or conveying. |
| | 345 | + | |
| | 346 | + | If you add terms to a covered work in accord with this section, you must place, in |
| | 347 | + | the relevant source files, a statement of the additional terms that apply to those |
| | 348 | + | files, or a notice indicating where to find the applicable terms. |
| | 349 | + | |
| | 350 | + | Additional terms, permissive or non-permissive, may be stated in the form of a |
| | 351 | + | separately written license, or stated as exceptions; the above requirements apply |
| | 352 | + | either way. |
| | 353 | + | |
| | 354 | + | ### 8. Termination. |
| | 355 | + | |
| | 356 | + | You may not propagate or modify a covered work except as expressly provided under |
| | 357 | + | this License. Any attempt otherwise to propagate or modify it is void, and will |
| | 358 | + | automatically terminate your rights under this License (including any patent licenses |
| | 359 | + | granted under the third paragraph of section 11). |
| | 360 | + | |
| | 361 | + | However, if you cease all violation of this License, then your license from a |
| | 362 | + | particular copyright holder is reinstated (a) provisionally, unless and until the |
| | 363 | + | copyright holder explicitly and finally terminates your license, and (b) permanently, |
| | 364 | + | if the copyright holder fails to notify you of the violation by some reasonable means |
| | 365 | + | prior to 60 days after the cessation. |
| | 366 | + | |
| | 367 | + | Moreover, your license from a particular copyright holder is reinstated permanently |
| | 368 | + | if the copyright holder notifies you of the violation by some reasonable means, this |
| | 369 | + | is the first time you have received notice of violation of this License (for any |
| | 370 | + | work) from that copyright holder, and you cure the violation prior to 30 days after |
| | 371 | + | your receipt of the notice. |
| | 372 | + | |
| | 373 | + | Termination of your rights under this section does not terminate the licenses of |
| | 374 | + | parties who have received copies or rights from you under this License. If your |
| | 375 | + | rights have been terminated and not permanently reinstated, you do not qualify to |
| | 376 | + | receive new licenses for the same material under section 10. |
| | 377 | + | |
| | 378 | + | ### 9. Acceptance Not Required for Having Copies. |
| | 379 | + | |
| | 380 | + | You are not required to accept this License in order to receive or run a copy of the |
| | 381 | + | Program. Ancillary propagation of a covered work occurring solely as a consequence of |
| | 382 | + | using peer-to-peer transmission to receive a copy likewise does not require |
| | 383 | + | acceptance. However, nothing other than this License grants you permission to |
| | 384 | + | propagate or modify any covered work. These actions infringe copyright if you do not |
| | 385 | + | accept this License. Therefore, by modifying or propagating a covered work, you |
| | 386 | + | indicate your acceptance of this License to do so. |
| | 387 | + | |
| | 388 | + | ### 10. Automatic Licensing of Downstream Recipients. |
| | 389 | + | |
| | 390 | + | Each time you convey a covered work, the recipient automatically receives a license |
| | 391 | + | from the original licensors, to run, modify and propagate that work, subject to this |
| | 392 | + | License. You are not responsible for enforcing compliance by third parties with this |
| | 393 | + | License. |
| | 394 | + | |
| | 395 | + | An “entity transaction” is a transaction transferring control of an |
| | 396 | + | organization, or substantially all assets of one, or subdividing an organization, or |
| | 397 | + | merging organizations. If propagation of a covered work results from an entity |
| | 398 | + | transaction, each party to that transaction who receives a copy of the work also |
| | 399 | + | receives whatever licenses to the work the party's predecessor in interest had or |
| | 400 | + | could give under the previous paragraph, plus a right to possession of the |
| | 401 | + | Corresponding Source of the work from the predecessor in interest, if the predecessor |
| | 402 | + | has it or can get it with reasonable efforts. |
| | 403 | + | |
| | 404 | + | You may not impose any further restrictions on the exercise of the rights granted or |
| | 405 | + | affirmed under this License. For example, you may not impose a license fee, royalty, |
| | 406 | + | or other charge for exercise of rights granted under this License, and you may not |
| | 407 | + | initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging |
| | 408 | + | that any patent claim is infringed by making, using, selling, offering for sale, or |
| | 409 | + | importing the Program or any portion of it. |
| | 410 | + | |
| | 411 | + | ### 11. Patents. |
| | 412 | + | |
| | 413 | + | A “contributor” is a copyright holder who authorizes use under this |
| | 414 | + | License of the Program or a work on which the Program is based. The work thus |
| | 415 | + | licensed is called the contributor's “contributor version”. |
| | 416 | + | |
| | 417 | + | A contributor's “essential patent claims” are all patent claims owned or |
| | 418 | + | controlled by the contributor, whether already acquired or hereafter acquired, that |
| | 419 | + | would be infringed by some manner, permitted by this License, of making, using, or |
| | 420 | + | selling its contributor version, but do not include claims that would be infringed |
| | 421 | + | only as a consequence of further modification of the contributor version. For |
| | 422 | + | purposes of this definition, “control” includes the right to grant patent |
| | 423 | + | sublicenses in a manner consistent with the requirements of this License. |
| | 424 | + | |
| | 425 | + | Each contributor grants you a non-exclusive, worldwide, royalty-free patent license |
| | 426 | + | under the contributor's essential patent claims, to make, use, sell, offer for sale, |
| | 427 | + | import and otherwise run, modify and propagate the contents of its contributor |
| | 428 | + | version. |
| | 429 | + | |
| | 430 | + | In the following three paragraphs, a “patent license” is any express |
| | 431 | + | agreement or commitment, however denominated, not to enforce a patent (such as an |
| | 432 | + | express permission to practice a patent or covenant not to sue for patent |
| | 433 | + | infringement). To “grant” such a patent license to a party means to make |
| | 434 | + | such an agreement or commitment not to enforce a patent against the party. |
| | 435 | + | |
| | 436 | + | If you convey a covered work, knowingly relying on a patent license, and the |
| | 437 | + | Corresponding Source of the work is not available for anyone to copy, free of charge |
| | 438 | + | and under the terms of this License, through a publicly available network server or |
| | 439 | + | other readily accessible means, then you must either (1) cause the Corresponding |
| | 440 | + | Source to be so available, or (2) arrange to deprive yourself of the benefit of the |
| | 441 | + | patent license for this particular work, or (3) arrange, in a manner consistent with |
| | 442 | + | the requirements of this License, to extend the patent license to downstream |
| | 443 | + | recipients. “Knowingly relying” means you have actual knowledge that, but |
| | 444 | + | for the patent license, your conveying the covered work in a country, or your |
| | 445 | + | recipient's use of the covered work in a country, would infringe one or more |
| | 446 | + | identifiable patents in that country that you have reason to believe are valid. |
| | 447 | + | |
| | 448 | + | If, pursuant to or in connection with a single transaction or arrangement, you |
| | 449 | + | convey, or propagate by procuring conveyance of, a covered work, and grant a patent |
| | 450 | + | license to some of the parties receiving the covered work authorizing them to use, |
| | 451 | + | propagate, modify or convey a specific copy of the covered work, then the patent |
| | 452 | + | license you grant is automatically extended to all recipients of the covered work and |
| | 453 | + | works based on it. |
| | 454 | + | |
| | 455 | + | A patent license is “discriminatory” if it does not include within the |
| | 456 | + | scope of its coverage, prohibits the exercise of, or is conditioned on the |
| | 457 | + | non-exercise of one or more of the rights that are specifically granted under this |
| | 458 | + | License. You may not convey a covered work if you are a party to an arrangement with |
| | 459 | + | a third party that is in the business of distributing software, under which you make |
| | 460 | + | payment to the third party based on the extent of your activity of conveying the |
| | 461 | + | work, and under which the third party grants, to any of the parties who would receive |
| | 462 | + | the covered work from you, a discriminatory patent license (a) in connection with |
| | 463 | + | copies of the covered work conveyed by you (or copies made from those copies), or (b) |
| | 464 | + | primarily for and in connection with specific products or compilations that contain |
| | 465 | + | the covered work, unless you entered into that arrangement, or that patent license |
| | 466 | + | was granted, prior to 28 March 2007. |
| | 467 | + | |
| | 468 | + | Nothing in this License shall be construed as excluding or limiting any implied |
| | 469 | + | license or other defenses to infringement that may otherwise be available to you |
| | 470 | + | under applicable patent law. |
| | 471 | + | |
| | 472 | + | ### 12. No Surrender of Others' Freedom. |
| | 473 | + | |
| | 474 | + | If conditions are imposed on you (whether by court order, agreement or otherwise) |
| | 475 | + | that contradict the conditions of this License, they do not excuse you from the |
| | 476 | + | conditions of this License. If you cannot convey a covered work so as to satisfy |
| | 477 | + | simultaneously your obligations under this License and any other pertinent |
| | 478 | + | obligations, then as a consequence you may not convey it at all. For example, if you |
| | 479 | + | agree to terms that obligate you to collect a royalty for further conveying from |
| | 480 | + | those to whom you convey the Program, the only way you could satisfy both those terms |
| | 481 | + | and this License would be to refrain entirely from conveying the Program. |
| | 482 | + | |
| | 483 | + | ### 13. Use with the GNU Affero General Public License. |
| | 484 | + | |
| | 485 | + | Notwithstanding any other provision of this License, you have permission to link or |
| | 486 | + | combine any covered work with a work licensed under version 3 of the GNU Affero |
| | 487 | + | General Public License into a single combined work, and to convey the resulting work. |
| | 488 | + | The terms of this License will continue to apply to the part which is the covered |
| | 489 | + | work, but the special requirements of the GNU Affero General Public License, section |
| | 490 | + | 13, concerning interaction through a network will apply to the combination as such. |
| | 491 | + | |
| | 492 | + | ### 14. Revised Versions of this License. |
| | 493 | + | |
| | 494 | + | The Free Software Foundation may publish revised and/or new versions of the GNU |
| | 495 | + | General Public License from time to time. Such new versions will be similar in spirit |
| | 496 | + | to the present version, but may differ in detail to address new problems or concerns. |
| | 497 | + | |
| | 498 | + | Each version is given a distinguishing version number. If the Program specifies that |
| | 499 | + | a certain numbered version of the GNU General Public License “or any later |
| | 500 | + | version” applies to it, you have the option of following the terms and |
| | 501 | + | conditions either of that numbered version or of any later version published by the |
| | 502 | + | Free Software Foundation. If the Program does not specify a version number of the GNU |
| | 503 | + | General Public License, you may choose any version ever published by the Free |
| | 504 | + | Software Foundation. |
| | 505 | + | |
| | 506 | + | If the Program specifies that a proxy can decide which future versions of the GNU |
| | 507 | + | General Public License can be used, that proxy's public statement of acceptance of a |
| | 508 | + | version permanently authorizes you to choose that version for the Program. |
| | 509 | + | |
| | 510 | + | Later license versions may give you additional or different permissions. However, no |
| | 511 | + | additional obligations are imposed on any author or copyright holder as a result of |
| | 512 | + | your choosing to follow a later version. |
| | 513 | + | |
| | 514 | + | ### 15. Disclaimer of Warranty. |
| | 515 | + | |
| | 516 | + | THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. |
| | 517 | + | EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES |
| | 518 | + | PROVIDE THE PROGRAM “AS IS” WITHOUT WARRANTY OF ANY KIND, EITHER |
| | 519 | + | EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF |
| | 520 | + | MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE |
| | 521 | + | QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE |
| | 522 | + | DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. |
| | 523 | + | |
| | 524 | + | ### 16. Limitation of Liability. |
| | 525 | + | |
| | 526 | + | IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY |
| | 527 | + | COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM AS |
| | 528 | + | PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, |
| | 529 | + | INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE |
| | 530 | + | PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE |
| | 531 | + | OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE |
| | 532 | + | WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE |
| | 533 | + | POSSIBILITY OF SUCH DAMAGES. |
| | 534 | + | |
| | 535 | + | ### 17. Interpretation of Sections 15 and 16. |
| | 536 | + | |
| | 537 | + | If the disclaimer of warranty and limitation of liability provided above cannot be |
| | 538 | + | given local legal effect according to their terms, reviewing courts shall apply local |
| | 539 | + | law that most closely approximates an absolute waiver of all civil liability in |
| | 540 | + | connection with the Program, unless a warranty or assumption of liability accompanies |
| | 541 | + | a copy of the Program in return for a fee. |
| | 542 | + | |
| | 543 | + | END OF TERMS AND CONDITIONS |
| | 544 | + | |
| | 545 | + | ## How to Apply These Terms to Your New Programs |
| | 546 | + | |
| | 547 | + | If you develop a new program, and you want it to be of the greatest possible use to |
| | 548 | + | the public, the best way to achieve this is to make it free software which everyone |
| | 549 | + | can redistribute and change under these terms. |
| | 550 | + | |
| | 551 | + | To do so, attach the following notices to the program. It is safest to attach them |
| | 552 | + | to the start of each source file to most effectively state the exclusion of warranty; |
| | 553 | + | and each file should have at least the “copyright” line and a pointer to |
| | 554 | + | where the full notice is found. |
| | 555 | + | |
| | 556 | + | <one line to give the program's name and a brief idea of what it does.> |
| | 557 | + | Copyright (C) <year> <name of author> |
| | 558 | + | |
| | 559 | + | This program is free software: you can redistribute it and/or modify |
| | 560 | + | it under the terms of the GNU General Public License as published by |
| | 561 | + | the Free Software Foundation, either version 3 of the License, or |
| | 562 | + | (at your option) any later version. |
| | 563 | + | |
| | 564 | + | This program is distributed in the hope that it will be useful, |
| | 565 | + | but WITHOUT ANY WARRANTY; without even the implied warranty of |
| | 566 | + | MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the |
| | 567 | + | GNU General Public License for more details. |
| | 568 | + | |
| | 569 | + | You should have received a copy of the GNU General Public License |
| | 570 | + | along with this program. If not, see <https://www.gnu.org/licenses/>. |
| | 571 | + | |
| | 572 | + | Also add information on how to contact you by electronic and paper mail. |
| | 573 | + | |
| | 574 | + | If the program does terminal interaction, make it output a short notice like this |
| | 575 | + | when it starts in an interactive mode: |
| | 576 | + | |
| | 577 | + | <program> Copyright (C) <year> <name of author> |
| | 578 | + | This program comes with ABSOLUTELY NO WARRANTY; for details type 'show w'. |
| | 579 | + | This is free software, and you are welcome to redistribute it |
| | 580 | + | under certain conditions; type 'show c' for details. |
| | 581 | + | |
| | 582 | + | The hypothetical commands 'show w' and 'show c' should show the appropriate parts of |
| | 583 | + | the General Public License. Of course, your program's commands might be different; |
| | 584 | + | for a GUI interface, you would use an “about box”. |
| | 585 | + | |
| | 586 | + | You should also get your employer (if you work as a programmer) or school, if any, to |
| | 587 | + | sign a “copyright disclaimer” for the program, if necessary. For more |
| | 588 | + | information on this, and how to apply and follow the GNU GPL, see |
| | 589 | + | <<https://www.gnu.org/licenses/>>. |
| | 590 | + | |
| | 591 | + | The GNU General Public License does not permit incorporating your program into |
| | 592 | + | proprietary programs. If your program is a subroutine library, you may consider it |
| | 593 | + | more useful to permit linking proprietary applications with the library. If this is |
| | 594 | + | what you want to do, use the GNU Lesser General Public License instead of this |
| | 595 | + | License. But first, please read |
| | 596 | + | <<https://www.gnu.org/philosophy/why-not-lgpl.html>>. |
