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