By contrast, 15 | the GNU General Public License is intended to guarantee your freedom to 16 | share and change all versions of a program--to make sure it remains free 17 | software for all its users. We, the Free Software Foundation, use the 18 | GNU General Public License for most of our software; it applies also to 19 | any other work released this way by its authors. You can apply it to 20 | your programs, too. 21 | 22 | When we speak of free software, we are referring to freedom, not 23 | price. Our General Public Licenses are designed to make sure that you 24 | have the freedom to distribute copies of free software (and charge for 25 | them if you wish), that you receive source code or can get it if you 26 | want it, that you can change the software or use pieces of it in new 27 | free programs, and that you know you can do these things. 28 | 29 | To protect your rights, we need to prevent others from denying you 30 | these rights or asking you to surrender the rights. Therefore, you have 31 | certain responsibilities if you distribute copies of the software, or if 32 | you modify it: responsibilities to respect the freedom of others. 33 | 34 | For example, if you distribute copies of such a program, whether 35 | gratis or for a fee, you must pass on to the recipients the same 36 | freedoms that you received. You must make sure that they, too, receive 37 | or can get the source code. And you must show them these terms so they 38 | know their rights. 39 | 40 | Developers that use the GNU GPL protect your rights with two steps: 41 | (1) assert copyright on the software, and (2) offer you this License 42 | giving you legal permission to copy, distribute and/or modify it. 43 | 44 | For the developers' and authors' protection, the GPL clearly explains 45 | that there is no warranty for this free software. For both users' and 46 | authors' sake, the GPL requires that modified versions be marked as 47 | changed, so that their problems will not be attributed erroneously to 48 | authors of previous versions. 49 | 50 | Some devices are designed to deny users access to install or run 51 | modified versions of the software inside them, although the manufacturer 52 | can do so. This is fundamentally incompatible with the aim of 53 | protecting users' freedom to change the software. The systematic 54 | pattern of such abuse occurs in the area of products for individuals to 55 | use, which is precisely where it is most unacceptable. Therefore, we 56 | have designed this version of the GPL to prohibit the practice for those 57 | products. If such problems arise substantially in other domains, we 58 | stand ready to extend this provision to those domains in future versions 59 | of the GPL, as needed to protect the freedom of users. 60 | 61 | Finally, every program is threatened constantly by software patents. 62 | States should not allow patents to restrict development and use of 63 | software on general-purpose computers, but in those that do, we wish to 64 | avoid the special danger that patents applied to a free program could 65 | make it effectively proprietary. To prevent this, the GPL assures that 66 | patents cannot be used to render the program non-free. 67 | 68 | The precise terms and conditions for copying, distribution and 69 | modification follow. 70 | 71 | TERMS AND CONDITIONS 72 | 73 | 0. Definitions. 74 | 75 | "This License" refers to version 3 of the GNU General Public License. 76 | 77 | "Copyright" also means copyright-like laws that apply to other kinds of 78 | works, such as semiconductor masks. 79 | 80 | "The Program" refers to any copyrightable work licensed under this 81 | License. Each licensee is addressed as "you". "Licensees" and 82 | "recipients" may be individuals or organizations. 83 | 84 | To "modify" a work means to copy from or adapt all or part of the work 85 | in a fashion requiring copyright permission, other than the making of an 86 | exact copy. The resulting work is called a "modified version" of the 87 | earlier work or a work "based on" the earlier work. 88 | 89 | A "covered work" means either the unmodified Program or a work based 90 | on the Program. 91 | 92 | To "propagate" a work means to do anything with it that, without 93 | permission, would make you directly or secondarily liable for 94 | infringement under applicable copyright law, except executing it on a 95 | computer or modifying a private copy. Propagation includes copying, 96 | distribution (with or without modification), making available to the 97 | public, and in some countries other activities as well. 98 | 99 | To "convey" a work means any kind of propagation that enables other 100 | parties to make or receive copies. Mere interaction with a user through 101 | a computer network, with no transfer of a copy, is not conveying. 102 | 103 | An interactive user interface displays "Appropriate Legal Notices" 104 | to the extent that it includes a convenient and prominently visible 105 | feature that (1) displays an appropriate copyright notice, and (2) 106 | tells the user that there is no warranty for the work (except to the 107 | extent that warranties are provided), that licensees may convey the 108 | work under this License, and how to view a copy of this License. If 109 | the interface presents a list of user commands or options, such as a 110 | menu, a prominent item in the list meets this criterion. 111 | 112 | 1. Source Code. 113 | 114 | The "source code" for a work means the preferred form of the work 115 | for making modifications to it. "Object code" means any non-source 116 | form of a work. 117 | 118 | A "Standard Interface" means an interface that either is an official 119 | standard defined by a recognized standards body, or, in the case of 120 | interfaces specified for a particular programming language, one that 121 | is widely used among developers working in that language. 122 | 123 | The "System Libraries" of an executable work include anything, other 124 | than the work as a whole, that (a) is included in the normal form of 125 | packaging a Major Component, but which is not part of that Major 126 | Component, and (b) serves only to enable use of the work with that 127 | Major Component, or to implement a Standard Interface for which an 128 | implementation is available to the public in source code form. A 129 | "Major Component", in this context, means a major essential component 130 | (kernel, window system, and so on) of the specific operating system 131 | (if any) on which the executable work runs, or a compiler used to 132 | produce the work, or an object code interpreter used to run it. 133 | 134 | The "Corresponding Source" for a work in object code form means all 135 | the source code needed to generate, install, and (for an executable 136 | work) run the object code and to modify the work, including scripts to 137 | control those activities. However, it does not include the work's 138 | System Libraries, or general-purpose tools or generally available free 139 | programs which are used unmodified in performing those activities but 140 | which are not part of the work. For example, Corresponding Source 141 | includes interface definition files associated with source files for 142 | the work, and the source code for shared libraries and dynamically 143 | linked subprograms that the work is specifically designed to require, 144 | such as by intimate data communication or control flow between those 145 | subprograms and other parts of the work. 146 | 147 | The Corresponding Source need not include anything that users 148 | can regenerate automatically from other parts of the Corresponding 149 | Source. 150 | 151 | The Corresponding Source for a work in source code form is that 152 | same work. 153 | 154 | 2. Basic Permissions. 155 | 156 | All rights granted under this License are granted for the term of 157 | copyright on the Program, and are irrevocable provided the stated 158 | conditions are met. This License explicitly affirms your unlimited 159 | permission to run the unmodified Program. The output from running a 160 | covered work is covered by this License only if the output, given its 161 | content, constitutes a covered work. This License acknowledges your 162 | rights of fair use or other equivalent, as provided by copyright law. 163 | 164 | You may make, run and propagate covered works that you do not 165 | convey, without conditions so long as your license otherwise remains 166 | in force. You may convey covered works to others for the sole purpose 167 | of having them make modifications exclusively for you, or provide you 168 | with facilities for running those works, provided that you comply with 169 | the terms of this License in conveying all material for which you do 170 | not control copyright. Those thus making or running the covered works 171 | for you must do so exclusively on your behalf, under your direction 172 | and control, on terms that prohibit them from making any copies of 173 | your copyrighted material outside their relationship with you. 174 | 175 | Conveying under any other circumstances is permitted solely under 176 | the conditions stated below. Sublicensing is not allowed; section 10 177 | makes it unnecessary. 178 | 179 | 3. Protecting Users' Legal Rights From Anti-Circumvention Law. 180 | 181 | No covered work shall be deemed part of an effective technological 182 | measure under any applicable law fulfilling obligations under article 183 | 11 of the WIPO copyright treaty adopted on 20 December 1996, or 184 | similar laws prohibiting or restricting circumvention of such 185 | measures. 186 | 187 | When you convey a covered work, you waive any legal power to forbid 188 | circumvention of technological measures to the extent such circumvention 189 | is effected by exercising rights under this License with respect to 190 | the covered work, and you disclaim any intention to limit operation or 191 | modification of the work as a means of enforcing, against the work's 192 | users, your or third parties' legal rights to forbid circumvention of 193 | technological measures. 194 | 195 | 4. Conveying Verbatim Copies. 196 | 197 | You may convey verbatim copies of the Program's source code as you 198 | receive it, in any medium, provided that you conspicuously and 199 | appropriately publish on each copy an appropriate copyright notice; 200 | keep intact all notices stating that this License and any 201 | non-permissive terms added in accord with section 7 apply to the code; 202 | keep intact all notices of the absence of any warranty; and give all 203 | recipients a copy of this License along with the Program. 204 | 205 | You may charge any price or no price for each copy that you convey, 206 | and you may offer support or warranty protection for a fee. 207 | 208 | 5. Conveying Modified Source Versions. 209 | 210 | You may convey a work based on the Program, or the modifications to 211 | produce it from the Program, in the form of source code under the 212 | terms of section 4, provided that you also meet all of these conditions: 213 | 214 | a) The work must carry prominent notices stating that you modified 215 | it, and giving a relevant date. 216 | 217 | b) The work must carry prominent notices stating that it is 218 | released under this License and any conditions added under section 219 | 7. This requirement modifies the requirement in section 4 to 220 | "keep intact all notices". 221 | 222 | c) You must license the entire work, as a whole, under this 223 | License to anyone who comes into possession of a copy. This 224 | License will therefore apply, along with any applicable section 7 225 | additional terms, to the whole of the work, and all its parts, 226 | regardless of how they are packaged. This License gives no 227 | permission to license the work in any other way, but it does not 228 | invalidate such permission if you have separately received it. 229 | 230 | d) If the work has interactive user interfaces, each must display 231 | Appropriate Legal Notices; however, if the Program has interactive 232 | interfaces that do not display Appropriate Legal Notices, your 233 | work need not make them do so. 234 | 235 | A compilation of a covered work with other separate and independent 236 | works, which are not by their nature extensions of the covered work, 237 | and which are not combined with it such as to form a larger program, 238 | in or on a volume of a storage or distribution medium, is called an 239 | "aggregate" if the compilation and its resulting copyright are not 240 | used to limit the access or legal rights of the compilation's users 241 | beyond what the individual works permit. Inclusion of a covered work 242 | in an aggregate does not cause this License to apply to the other 243 | parts of the aggregate. 244 | 245 | 6. Conveying Non-Source Forms. 246 | 247 | You may convey a covered work in object code form under the terms 248 | of sections 4 and 5, provided that you also convey the 249 | machine-readable Corresponding Source under the terms of this License, 250 | in one of these ways: 251 | 252 | a) Convey the object code in, or embodied in, a physical product 253 | (including a physical distribution medium), accompanied by the 254 | Corresponding Source fixed on a durable physical medium 255 | customarily used for software interchange. 256 | 257 | b) Convey the object code in, or embodied in, a physical product 258 | (including a physical distribution medium), accompanied by a 259 | written offer, valid for at least three years and valid for as 260 | long as you offer spare parts or customer support for that product 261 | model, to give anyone who possesses the object code either (1) a 262 | copy of the Corresponding Source for all the software in the 263 | product that is covered by this License, on a durable physical 264 | medium customarily used for software interchange, for a price no 265 | more than your reasonable cost of physically performing this 266 | conveying of source, or (2) access to copy the 267 | Corresponding Source from a network server at no charge. 268 | 269 | c) Convey individual copies of the object code with a copy of the 270 | written offer to provide the Corresponding Source. This 271 | alternative is allowed only occasionally and noncommercially, and 272 | only if you received the object code with such an offer, in accord 273 | with subsection 6b. 274 | 275 | d) Convey the object code by offering access from a designated 276 | place (gratis or for a charge), and offer equivalent access to the 277 | Corresponding Source in the same way through the same place at no 278 | further charge. You need not require recipients to copy the 279 | Corresponding Source along with the object code. If the place to 280 | copy the object code is a network server, the Corresponding Source 281 | may be on a different server (operated by you or a third party) 282 | that supports equivalent copying facilities, provided you maintain 283 | clear directions next to the object code saying where to find the 284 | Corresponding Source. Regardless of what server hosts the 285 | Corresponding Source, you remain obligated to ensure that it is 286 | available for as long as needed to satisfy these requirements. 287 | 288 | e) Convey the object code using peer-to-peer transmission, provided 289 | you inform other peers where the object code and Corresponding 290 | Source of the work are being offered to the general public at no 291 | charge under subsection 6d. 292 | 293 | A separable portion of the object code, whose source code is excluded 294 | from the Corresponding Source as a System Library, need not be 295 | included in conveying the object code work. 296 | 297 | A "User Product" is either (1) a "consumer product", which means any 298 | tangible personal property which is normally used for personal, family, 299 | or household purposes, or (2) anything designed or sold for incorporation 300 | into a dwelling. In determining whether a product is a consumer product, 301 | doubtful cases shall be resolved in favor of coverage. For a particular 302 | product received by a particular user, "normally used" refers to a 303 | typical or common use of that class of product, regardless of the status 304 | of the particular user or of the way in which the particular user 305 | actually uses, or expects or is expected to use, the product. A product 306 | is a consumer product regardless of whether the product has substantial 307 | commercial, industrial or non-consumer uses, unless such uses represent 308 | the only significant mode of use of the product. 309 | 310 | "Installation Information" for a User Product means any methods, 311 | procedures, authorization keys, or other information required to install 312 | and execute modified versions of a covered work in that User Product from 313 | a modified version of its Corresponding Source. The information must 314 | suffice to ensure that the continued functioning of the modified object 315 | code is in no case prevented or interfered with solely because 316 | modification has been made. 317 | 318 | If you convey an object code work under this section in, or with, or 319 | specifically for use in, a User Product, and the conveying occurs as 320 | part of a transaction in which the right of possession and use of the 321 | User Product is transferred to the recipient in perpetuity or for a 322 | fixed term (regardless of how the transaction is characterized), the 323 | Corresponding Source conveyed under this section must be accompanied 324 | by the Installation Information. But this requirement does not apply 325 | if neither you nor any third party retains the ability to install 326 | modified object code on the User Product (for example, the work has 327 | been installed in ROM). 328 | 329 | The requirement to provide Installation Information does not include a 330 | requirement to continue to provide support service, warranty, or updates 331 | for a work that has been modified or installed by the recipient, or for 332 | the User Product in which it has been modified or installed. Access to a 333 | network may be denied when the modification itself materially and 334 | adversely affects the operation of the network or violates the rules and 335 | protocols for communication across the network. 336 | 337 | Corresponding Source conveyed, and Installation Information provided, 338 | in accord with this section must be in a format that is publicly 339 | documented (and with an implementation available to the public in 340 | source code form), and must require no special password or key for 341 | unpacking, reading or copying. 342 | 343 | 7. Additional Terms. 344 | 345 | "Additional permissions" are terms that supplement the terms of this 346 | License by making exceptions from one or more of its conditions. 347 | Additional permissions that are applicable to the entire Program shall 348 | be treated as though they were included in this License, to the extent 349 | that they are valid under applicable law. If additional permissions 350 | apply only to part of the Program, that part may be used separately 351 | under those permissions, but the entire Program remains governed by 352 | this License without regard to the additional permissions. 353 | 354 | When you convey a copy of a covered work, you may at your option 355 | remove any additional permissions from that copy, or from any part of 356 | it. (Additional permissions may be written to require their own 357 | removal in certain cases when you modify the work.) You may place 358 | additional permissions on material, added by you to a covered work, 359 | for which you have or can give appropriate copyright permission. 360 | 361 | Notwithstanding any other provision of this License, for material you 362 | add to a covered work, you may (if authorized by the copyright holders of 363 | that material) supplement the terms of this License with terms: 364 | 365 | a) Disclaiming warranty or limiting liability differently from the 366 | terms of sections 15 and 16 of this License; or 367 | 368 | b) Requiring preservation of specified reasonable legal notices or 369 | author attributions in that material or in the Appropriate Legal 370 | Notices displayed by works containing it; or 371 | 372 | c) Prohibiting misrepresentation of the origin of that material, or 373 | requiring that modified versions of such material be marked in 374 | reasonable ways as different from the original version; or 375 | 376 | d) Limiting the use for publicity purposes of names of licensors or 377 | authors of the material; or 378 | 379 | e) Declining to grant rights under trademark law for use of some 380 | trade names, trademarks, or service marks; or 381 | 382 | f) Requiring indemnification of licensors and authors of that 383 | material by anyone who conveys the material (or modified versions of 384 | it) with contractual assumptions of liability to the recipient, for 385 | any liability that these contractual assumptions directly impose on 386 | those licensors and authors. 387 | 388 | All other non-permissive additional terms are considered "further 389 | restrictions" within the meaning of section 10. If the Program as you 390 | received it, or any part of it, contains a notice stating that it is 391 | governed by this License along with a term that is a further 392 | restriction, you may remove that term. If a license document contains 393 | a further restriction but permits relicensing or conveying under this 394 | License, you may add to a covered work material governed by the terms 395 | of that license document, provided that the further restriction does 396 | not survive such relicensing or conveying. 397 | 398 | If you add terms to a covered work in accord with this section, you 399 | must place, in the relevant source files, a statement of the 400 | additional terms that apply to those files, or a notice indicating 401 | where to find the applicable terms. 402 | 403 | Additional terms, permissive or non-permissive, may be stated in the 404 | form of a separately written license, or stated as exceptions; 405 | the above requirements apply either way. 406 | 407 | 8. Termination. 408 | 409 | You may not propagate or modify a covered work except as expressly 410 | provided under this License. Any attempt otherwise to propagate or 411 | modify it is void, and will automatically terminate your rights under 412 | this License (including any patent licenses granted under the third 413 | paragraph of section 11). 414 | 415 | However, if you cease all violation of this License, then your 416 | license from a particular copyright holder is reinstated (a) 417 | provisionally, unless and until the copyright holder explicitly and 418 | finally terminates your license, and (b) permanently, if the copyright 419 | holder fails to notify you of the violation by some reasonable means 420 | prior to 60 days after the cessation. 421 | 422 | Moreover, your license from a particular copyright holder is 423 | reinstated permanently if the copyright holder notifies you of the 424 | violation by some reasonable means, this is the first time you have 425 | received notice of violation of this License (for any work) from that 426 | copyright holder, and you cure the violation prior to 30 days after 427 | your receipt of the notice. 428 | 429 | Termination of your rights under this section does not terminate the 430 | licenses of parties who have received copies or rights from you under 431 | this License. If your rights have been terminated and not permanently 432 | reinstated, you do not qualify to receive new licenses for the same 433 | material under section 10. 434 | 435 | 9. Acceptance Not Required for Having Copies. 436 | 437 | You are not required to accept this License in order to receive or 438 | run a copy of the Program. Ancillary propagation of a covered work 439 | occurring solely as a consequence of using peer-to-peer transmission 440 | to receive a copy likewise does not require acceptance. However, 441 | nothing other than this License grants you permission to propagate or 442 | modify any covered work. These actions infringe copyright if you do 443 | not accept this License. Therefore, by modifying or propagating a 444 | covered work, you indicate your acceptance of this License to do so. 445 | 446 | 10. Automatic Licensing of Downstream Recipients. 447 | 448 | Each time you convey a covered work, the recipient automatically 449 | receives a license from the original licensors, to run, modify and 450 | propagate that work, subject to this License. You are not responsible 451 | for enforcing compliance by third parties with this License. 452 | 453 | An "entity transaction" is a transaction transferring control of an 454 | organization, or substantially all assets of one, or subdividing an 455 | organization, or merging organizations. If propagation of a covered 456 | work results from an entity transaction, each party to that 457 | transaction who receives a copy of the work also receives whatever 458 | licenses to the work the party's predecessor in interest had or could 459 | give under the previous paragraph, plus a right to possession of the 460 | Corresponding Source of the work from the predecessor in interest, if 461 | the predecessor has it or can get it with reasonable efforts. 462 | 463 | You may not impose any further restrictions on the exercise of the 464 | rights granted or affirmed under this License. For example, you may 465 | not impose a license fee, royalty, or other charge for exercise of 466 | rights granted under this License, and you may not initiate litigation 467 | (including a cross-claim or counterclaim in a lawsuit) alleging that 468 | any patent claim is infringed by making, using, selling, offering for 469 | sale, or importing the Program or any portion of it. 470 | 471 | 11. Patents. 472 | 473 | A "contributor" is a copyright holder who authorizes use under this 474 | License of the Program or a work on which the Program is based. The 475 | work thus licensed is called the contributor's "contributor version". 476 | 477 | A contributor's "essential patent claims" are all patent claims 478 | owned or controlled by the contributor, whether already acquired or 479 | hereafter acquired, that would be infringed by some manner, permitted 480 | by this License, of making, using, or selling its contributor version, 481 | but do not include claims that would be infringed only as a 482 | consequence of further modification of the contributor version. For 483 | purposes of this definition, "control" includes the right to grant 484 | patent sublicenses in a manner consistent with the requirements of 485 | this License. 486 | 487 | Each contributor grants you a non-exclusive, worldwide, royalty-free 488 | patent license under the contributor's essential patent claims, to 489 | make, use, sell, offer for sale, import and otherwise run, modify and 490 | propagate the contents of its contributor version. 491 | 492 | In the following three paragraphs, a "patent license" is any express 493 | agreement or commitment, however denominated, not to enforce a patent 494 | (such as an express permission to practice a patent or covenant not to 495 | sue for patent infringement). To "grant" such a patent license to a 496 | party means to make such an agreement or commitment not to enforce a 497 | patent against the party. 498 | 499 | If you convey a covered work, knowingly relying on a patent license, 500 | and the Corresponding Source of the work is not available for anyone 501 | to copy, free of charge and under the terms of this License, through a 502 | publicly available network server or other readily accessible means, 503 | then you must either (1) cause the Corresponding Source to be so 504 | available, or (2) arrange to deprive yourself of the benefit of the 505 | patent license for this particular work, or (3) arrange, in a manner 506 | consistent with the requirements of this License, to extend the patent 507 | license to downstream recipients. "Knowingly relying" means you have 508 | actual knowledge that, but for the patent license, your conveying the 509 | covered work in a country, or your recipient's use of the covered work 510 | in a country, would infringe one or more identifiable patents in that 511 | country that you have reason to believe are valid. 512 | 513 | If, pursuant to or in connection with a single transaction or 514 | arrangement, you convey, or propagate by procuring conveyance of, a 515 | covered work, and grant a patent license to some of the parties 516 | receiving the covered work authorizing them to use, propagate, modify 517 | or convey a specific copy of the covered work, then the patent license 518 | you grant is automatically extended to all recipients of the covered 519 | work and works based on it. 520 | 521 | A patent license is "discriminatory" if it does not include within 522 | the scope of its coverage, prohibits the exercise of, or is 523 | conditioned on the non-exercise of one or more of the rights that are 524 | specifically granted under this License. You may not convey a covered 525 | work if you are a party to an arrangement with a third party that is 526 | in the business of distributing software, under which you make payment 527 | to the third party based on the extent of your activity of conveying 528 | the work, and under which the third party grants, to any of the 529 | parties who would receive the covered work from you, a discriminatory 530 | patent license (a) in connection with copies of the covered work 531 | conveyed by you (or copies made from those copies), or (b) primarily 532 | for and in connection with specific products or compilations that 533 | contain the covered work, unless you entered into that arrangement, 534 | or that patent license was granted, prior to 28 March 2007. 535 | 536 | Nothing in this License shall be construed as excluding or limiting 537 | any implied license or other defenses to infringement that may 538 | otherwise be available to you under applicable patent law. 539 | 540 | 12. No Surrender of Others' Freedom. 541 | 542 | If conditions are imposed on you (whether by court order, agreement or 543 | otherwise) that contradict the conditions of this License, they do not 544 | excuse you from the conditions of this License. If you cannot convey a 545 | covered work so as to satisfy simultaneously your obligations under this 546 | License and any other pertinent obligations, then as a consequence you may 547 | not convey it at all. For example, if you agree to terms that obligate you 548 | to collect a royalty for further conveying from those to whom you convey 549 | the Program, the only way you could satisfy both those terms and this 550 | License would be to refrain entirely from conveying the Program. 551 | 552 | 13. Use with the GNU Affero General Public License. 553 | 554 | Notwithstanding any other provision of this License, you have 555 | permission to link or combine any covered work with a work licensed 556 | under version 3 of the GNU Affero General Public License into a single 557 | combined work, and to convey the resulting work. The terms of this 558 | License will continue to apply to the part which is the covered work, 559 | but the special requirements of the GNU Affero General Public License, 560 | section 13, concerning interaction through a network will apply to the 561 | combination as such. 562 | 563 | 14. Revised Versions of this License. 564 | 565 | The Free Software Foundation may publish revised and/or new versions of 566 | the GNU General Public License from time to time. Such new versions will 567 | be similar in spirit to the present version, but may differ in detail to 568 | address new problems or concerns. 569 | 570 | Each version is given a distinguishing version number. If the 571 | Program specifies that a certain numbered version of the GNU General 572 | Public License "or any later version" applies to it, you have the 573 | option of following the terms and conditions either of that numbered 574 | version or of any later version published by the Free Software 575 | Foundation. If the Program does not specify a version number of the 576 | GNU General Public License, you may choose any version ever published 577 | by the Free Software Foundation. 578 | 579 | If the Program specifies that a proxy can decide which future 580 | versions of the GNU General Public License can be used, that proxy's 581 | public statement of acceptance of a version permanently authorizes you 582 | to choose that version for the Program. 583 | 584 | Later license versions may give you additional or different 585 | permissions. However, no additional obligations are imposed on any 586 | author or copyright holder as a result of your choosing to follow a 587 | later version. 588 | 589 | 15. Disclaimer of Warranty. 590 | 591 | THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY 592 | APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT 593 | HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY 594 | OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, 595 | THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR 596 | PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM 597 | IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF 598 | ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 599 | 600 | 16. Limitation of Liability. 601 | 602 | IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 603 | WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS 604 | THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY 605 | GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE 606 | USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF 607 | DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD 608 | PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), 609 | EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF 610 | SUCH DAMAGES. 611 | 612 | 17. Interpretation of Sections 15 and 16. 613 | 614 | If the disclaimer of warranty and limitation of liability provided 615 | above cannot be given local legal effect according to their terms, 616 | reviewing courts shall apply local law that most closely approximates 617 | an absolute waiver of all civil liability in connection with the 618 | Program, unless a warranty or assumption of liability accompanies a 619 | copy of the Program in return for a fee. 620 | 621 | END OF TERMS AND CONDITIONS 622 | 623 | How to Apply These Terms to Your New Programs 624 | 625 | If you develop a new program, and you want it to be of the greatest 626 | possible use to the public, the best way to achieve this is to make it 627 | free software which everyone can redistribute and change under these terms. 628 | 629 | To do so, attach the following notices to the program. It is safest 630 | to attach them to the start of each source file to most effectively 631 | state the exclusion of warranty; and each file should have at least 632 | the "copyright" line and a pointer to where the full notice is found. 633 | 634 | {one line to give the program's name and a brief idea of what it does.} 635 | Copyright (C) {year} {name of author} 636 | 637 | This program is free software: you can redistribute it and/or modify 638 | it under the terms of the GNU General Public License as published by 639 | the Free Software Foundation, either version 3 of the License, or 640 | (at your option) any later version. 641 | 642 | This program is distributed in the hope that it will be useful, 643 | but WITHOUT ANY WARRANTY; without even the implied warranty of 644 | MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the 645 | GNU General Public License for more details. 646 | 647 | You should have received a copy of the GNU General Public License 648 | along with this program. If not, see . 649 | 650 | Also add information on how to contact you by electronic and paper mail. 651 | 652 | If the program does terminal interaction, make it output a short 653 | notice like this when it starts in an interactive mode: 654 | 655 | {project} Copyright (C) {year} {fullname} 656 | This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. 657 | This is free software, and you are welcome to redistribute it 658 | under certain conditions; type `show c' for details. 659 | 660 | The hypothetical commands `show w' and `show c' should show the appropriate 661 | parts of the General Public License. Of course, your program's commands 662 | might be different; for a GUI interface, you would use an "about box". 663 | 664 | You should also get your employer (if you work as a programmer) or school, 665 | if any, to sign a "copyright disclaimer" for the program, if necessary. 666 | For more information on this, and how to apply and follow the GNU GPL, see 667 | . 668 | 669 | The GNU General Public License does not permit incorporating your program 670 | into proprietary programs. If your program is a subroutine library, you 671 | may consider it more useful to permit linking proprietary applications with 672 | the library. If this is what you want to do, use the GNU Lesser General 673 | Public License instead of this License. But first, please read 674 | . 675 | -------------------------------------------------------------------------------- /OPENSOURCELICENSES: -------------------------------------------------------------------------------- 1 | ### runnergroup 2 | 3 | https://github.com/txthinking/runnergroup 4 | 5 | The MIT License (MIT) 6 | 7 | Copyright (c) 2020-present Cloud https://www.txthinking.com 8 | 9 | Permission is hereby granted, free of charge, to any person obtaining a copy 10 | of this software and associated documentation files (the "Software"), to deal 11 | in the Software without restriction, including without limitation the rights 12 | to use, copy, modify, merge, publish, distribute, sublicense, and/or sell 13 | copies of the Software, and to permit persons to whom the Software is 14 | furnished to do so, subject to the following conditions: 15 | 16 | The above copyright notice and this permission notice shall be included in all 17 | copies or substantial portions of the Software. 18 | 19 | THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR 20 | IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, 21 | FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

By contrast, 45 | the GNU General Public License is intended to guarantee your freedom to 46 | share and change all versions of a program--to make sure it remains free 47 | software for all its users. We, the Free Software Foundation, use the 48 | GNU General Public License for most of our software; it applies also to 49 | any other work released this way by its authors. You can apply it to 50 | your programs, too. 51 | 52 | When we speak of free software, we are referring to freedom, not 53 | price. Our General Public Licenses are designed to make sure that you 54 | have the freedom to distribute copies of free software (and charge for 55 | them if you wish), that you receive source code or can get it if you 56 | want it, that you can change the software or use pieces of it in new 57 | free programs, and that you know you can do these things. 58 | 59 | To protect your rights, we need to prevent others from denying you 60 | these rights or asking you to surrender the rights. Therefore, you have 61 | certain responsibilities if you distribute copies of the software, or if 62 | you modify it: responsibilities to respect the freedom of others. 63 | 64 | For example, if you distribute copies of such a program, whether 65 | gratis or for a fee, you must pass on to the recipients the same 66 | freedoms that you received. You must make sure that they, too, receive 67 | or can get the source code. And you must show them these terms so they 68 | know their rights. 69 | 70 | Developers that use the GNU GPL protect your rights with two steps: 71 | (1) assert copyright on the software, and (2) offer you this License 72 | giving you legal permission to copy, distribute and/or modify it. 73 | 74 | For the developers' and authors' protection, the GPL clearly explains 75 | that there is no warranty for this free software. For both users' and 76 | authors' sake, the GPL requires that modified versions be marked as 77 | changed, so that their problems will not be attributed erroneously to 78 | authors of previous versions. 79 | 80 | Some devices are designed to deny users access to install or run 81 | modified versions of the software inside them, although the manufacturer 82 | can do so. This is fundamentally incompatible with the aim of 83 | protecting users' freedom to change the software. The systematic 84 | pattern of such abuse occurs in the area of products for individuals to 85 | use, which is precisely where it is most unacceptable. Therefore, we 86 | have designed this version of the GPL to prohibit the practice for those 87 | products. If such problems arise substantially in other domains, we 88 | stand ready to extend this provision to those domains in future versions 89 | of the GPL, as needed to protect the freedom of users. 90 | 91 | Finally, every program is threatened constantly by software patents. 92 | States should not allow patents to restrict development and use of 93 | software on general-purpose computers, but in those that do, we wish to 94 | avoid the special danger that patents applied to a free program could 95 | make it effectively proprietary. To prevent this, the GPL assures that 96 | patents cannot be used to render the program non-free. 97 | 98 | The precise terms and conditions for copying, distribution and 99 | modification follow. 100 | 101 | TERMS AND CONDITIONS 102 | 103 | 0. Definitions. 104 | 105 | "This License" refers to version 3 of the GNU General Public License. 106 | 107 | "Copyright" also means copyright-like laws that apply to other kinds of 108 | works, such as semiconductor masks. 109 | 110 | "The Program" refers to any copyrightable work licensed under this 111 | License. Each licensee is addressed as "you". "Licensees" and 112 | "recipients" may be individuals or organizations. 113 | 114 | To "modify" a work means to copy from or adapt all or part of the work 115 | in a fashion requiring copyright permission, other than the making of an 116 | exact copy. The resulting work is called a "modified version" of the 117 | earlier work or a work "based on" the earlier work. 118 | 119 | A "covered work" means either the unmodified Program or a work based 120 | on the Program. 121 | 122 | To "propagate" a work means to do anything with it that, without 123 | permission, would make you directly or secondarily liable for 124 | infringement under applicable copyright law, except executing it on a 125 | computer or modifying a private copy. Propagation includes copying, 126 | distribution (with or without modification), making available to the 127 | public, and in some countries other activities as well. 128 | 129 | To "convey" a work means any kind of propagation that enables other 130 | parties to make or receive copies. Mere interaction with a user through 131 | a computer network, with no transfer of a copy, is not conveying. 132 | 133 | An interactive user interface displays "Appropriate Legal Notices" 134 | to the extent that it includes a convenient and prominently visible 135 | feature that (1) displays an appropriate copyright notice, and (2) 136 | tells the user that there is no warranty for the work (except to the 137 | extent that warranties are provided), that licensees may convey the 138 | work under this License, and how to view a copy of this License. If 139 | the interface presents a list of user commands or options, such as a 140 | menu, a prominent item in the list meets this criterion. 141 | 142 | 1. Source Code. 143 | 144 | The "source code" for a work means the preferred form of the work 145 | for making modifications to it. "Object code" means any non-source 146 | form of a work. 147 | 148 | A "Standard Interface" means an interface that either is an official 149 | standard defined by a recognized standards body, or, in the case of 150 | interfaces specified for a particular programming language, one that 151 | is widely used among developers working in that language. 152 | 153 | The "System Libraries" of an executable work include anything, other 154 | than the work as a whole, that (a) is included in the normal form of 155 | packaging a Major Component, but which is not part of that Major 156 | Component, and (b) serves only to enable use of the work with that 157 | Major Component, or to implement a Standard Interface for which an 158 | implementation is available to the public in source code form. A 159 | "Major Component", in this context, means a major essential component 160 | (kernel, window system, and so on) of the specific operating system 161 | (if any) on which the executable work runs, or a compiler used to 162 | produce the work, or an object code interpreter used to run it. 163 | 164 | The "Corresponding Source" for a work in object code form means all 165 | the source code needed to generate, install, and (for an executable 166 | work) run the object code and to modify the work, including scripts to 167 | control those activities. However, it does not include the work's 168 | System Libraries, or general-purpose tools or generally available free 169 | programs which are used unmodified in performing those activities but 170 | which are not part of the work. For example, Corresponding Source 171 | includes interface definition files associated with source files for 172 | the work, and the source code for shared libraries and dynamically 173 | linked subprograms that the work is specifically designed to require, 174 | such as by intimate data communication or control flow between those 175 | subprograms and other parts of the work. 176 | 177 | The Corresponding Source need not include anything that users 178 | can regenerate automatically from other parts of the Corresponding 179 | Source. 180 | 181 | The Corresponding Source for a work in source code form is that 182 | same work. 183 | 184 | 2. Basic Permissions. 185 | 186 | All rights granted under this License are granted for the term of 187 | copyright on the Program, and are irrevocable provided the stated 188 | conditions are met. This License explicitly affirms your unlimited 189 | permission to run the unmodified Program. The output from running a 190 | covered work is covered by this License only if the output, given its 191 | content, constitutes a covered work. This License acknowledges your 192 | rights of fair use or other equivalent, as provided by copyright law. 193 | 194 | You may make, run and propagate covered works that you do not 195 | convey, without conditions so long as your license otherwise remains 196 | in force. You may convey covered works to others for the sole purpose 197 | of having them make modifications exclusively for you, or provide you 198 | with facilities for running those works, provided that you comply with 199 | the terms of this License in conveying all material for which you do 200 | not control copyright. Those thus making or running the covered works 201 | for you must do so exclusively on your behalf, under your direction 202 | and control, on terms that prohibit them from making any copies of 203 | your copyrighted material outside their relationship with you. 204 | 205 | Conveying under any other circumstances is permitted solely under 206 | the conditions stated below. Sublicensing is not allowed; section 10 207 | makes it unnecessary. 208 | 209 | 3. Protecting Users' Legal Rights From Anti-Circumvention Law. 210 | 211 | No covered work shall be deemed part of an effective technological 212 | measure under any applicable law fulfilling obligations under article 213 | 11 of the WIPO copyright treaty adopted on 20 December 1996, or 214 | similar laws prohibiting or restricting circumvention of such 215 | measures. 216 | 217 | When you convey a covered work, you waive any legal power to forbid 218 | circumvention of technological measures to the extent such circumvention 219 | is effected by exercising rights under this License with respect to 220 | the covered work, and you disclaim any intention to limit operation or 221 | modification of the work as a means of enforcing, against the work's 222 | users, your or third parties' legal rights to forbid circumvention of 223 | technological measures. 224 | 225 | 4. Conveying Verbatim Copies. 226 | 227 | You may convey verbatim copies of the Program's source code as you 228 | receive it, in any medium, provided that you conspicuously and 229 | appropriately publish on each copy an appropriate copyright notice; 230 | keep intact all notices stating that this License and any 231 | non-permissive terms added in accord with section 7 apply to the code; 232 | keep intact all notices of the absence of any warranty; and give all 233 | recipients a copy of this License along with the Program. 234 | 235 | You may charge any price or no price for each copy that you convey, 236 | and you may offer support or warranty protection for a fee. 237 | 238 | 5. Conveying Modified Source Versions. 239 | 240 | You may convey a work based on the Program, or the modifications to 241 | produce it from the Program, in the form of source code under the 242 | terms of section 4, provided that you also meet all of these conditions: 243 | 244 | a) The work must carry prominent notices stating that you modified 245 | it, and giving a relevant date. 246 | 247 | b) The work must carry prominent notices stating that it is 248 | released under this License and any conditions added under section 249 | 7. This requirement modifies the requirement in section 4 to 250 | "keep intact all notices". 251 | 252 | c) You must license the entire work, as a whole, under this 253 | License to anyone who comes into possession of a copy. This 254 | License will therefore apply, along with any applicable section 7 255 | additional terms, to the whole of the work, and all its parts, 256 | regardless of how they are packaged. This License gives no 257 | permission to license the work in any other way, but it does not 258 | invalidate such permission if you have separately received it. 259 | 260 | d) If the work has interactive user interfaces, each must display 261 | Appropriate Legal Notices; however, if the Program has interactive 262 | interfaces that do not display Appropriate Legal Notices, your 263 | work need not make them do so. 264 | 265 | A compilation of a covered work with other separate and independent 266 | works, which are not by their nature extensions of the covered work, 267 | and which are not combined with it such as to form a larger program, 268 | in or on a volume of a storage or distribution medium, is called an 269 | "aggregate" if the compilation and its resulting copyright are not 270 | used to limit the access or legal rights of the compilation's users 271 | beyond what the individual works permit. Inclusion of a covered work 272 | in an aggregate does not cause this License to apply to the other 273 | parts of the aggregate. 274 | 275 | 6. Conveying Non-Source Forms. 276 | 277 | You may convey a covered work in object code form under the terms 278 | of sections 4 and 5, provided that you also convey the 279 | machine-readable Corresponding Source under the terms of this License, 280 | in one of these ways: 281 | 282 | a) Convey the object code in, or embodied in, a physical product 283 | (including a physical distribution medium), accompanied by the 284 | Corresponding Source fixed on a durable physical medium 285 | customarily used for software interchange. 286 | 287 | b) Convey the object code in, or embodied in, a physical product 288 | (including a physical distribution medium), accompanied by a 289 | written offer, valid for at least three years and valid for as 290 | long as you offer spare parts or customer support for that product 291 | model, to give anyone who possesses the object code either (1) a 292 | copy of the Corresponding Source for all the software in the 293 | product that is covered by this License, on a durable physical 294 | medium customarily used for software interchange, for a price no 295 | more than your reasonable cost of physically performing this 296 | conveying of source, or (2) access to copy the 297 | Corresponding Source from a network server at no charge. 298 | 299 | c) Convey individual copies of the object code with a copy of the 300 | written offer to provide the Corresponding Source. This 301 | alternative is allowed only occasionally and noncommercially, and 302 | only if you received the object code with such an offer, in accord 303 | with subsection 6b. 304 | 305 | d) Convey the object code by offering access from a designated 306 | place (gratis or for a charge), and offer equivalent access to the 307 | Corresponding Source in the same way through the same place at no 308 | further charge. You need not require recipients to copy the 309 | Corresponding Source along with the object code. If the place to 310 | copy the object code is a network server, the Corresponding Source 311 | may be on a different server (operated by you or a third party) 312 | that supports equivalent copying facilities, provided you maintain 313 | clear directions next to the object code saying where to find the 314 | Corresponding Source. Regardless of what server hosts the 315 | Corresponding Source, you remain obligated to ensure that it is 316 | available for as long as needed to satisfy these requirements. 317 | 318 | e) Convey the object code using peer-to-peer transmission, provided 319 | you inform other peers where the object code and Corresponding 320 | Source of the work are being offered to the general public at no 321 | charge under subsection 6d. 322 | 323 | A separable portion of the object code, whose source code is excluded 324 | from the Corresponding Source as a System Library, need not be 325 | included in conveying the object code work. 326 | 327 | A "User Product" is either (1) a "consumer product", which means any 328 | tangible personal property which is normally used for personal, family, 329 | or household purposes, or (2) anything designed or sold for incorporation 330 | into a dwelling. In determining whether a product is a consumer product, 331 | doubtful cases shall be resolved in favor of coverage. For a particular 332 | product received by a particular user, "normally used" refers to a 333 | typical or common use of that class of product, regardless of the status 334 | of the particular user or of the way in which the particular user 335 | actually uses, or expects or is expected to use, the product. A product 336 | is a consumer product regardless of whether the product has substantial 337 | commercial, industrial or non-consumer uses, unless such uses represent 338 | the only significant mode of use of the product. 339 | 340 | "Installation Information" for a User Product means any methods, 341 | procedures, authorization keys, or other information required to install 342 | and execute modified versions of a covered work in that User Product from 343 | a modified version of its Corresponding Source. The information must 344 | suffice to ensure that the continued functioning of the modified object 345 | code is in no case prevented or interfered with solely because 346 | modification has been made. 347 | 348 | If you convey an object code work under this section in, or with, or 349 | specifically for use in, a User Product, and the conveying occurs as 350 | part of a transaction in which the right of possession and use of the 351 | User Product is transferred to the recipient in perpetuity or for a 352 | fixed term (regardless of how the transaction is characterized), the 353 | Corresponding Source conveyed under this section must be accompanied 354 | by the Installation Information. But this requirement does not apply 355 | if neither you nor any third party retains the ability to install 356 | modified object code on the User Product (for example, the work has 357 | been installed in ROM). 358 | 359 | The requirement to provide Installation Information does not include a 360 | requirement to continue to provide support service, warranty, or updates 361 | for a work that has been modified or installed by the recipient, or for 362 | the User Product in which it has been modified or installed. Access to a 363 | network may be denied when the modification itself materially and 364 | adversely affects the operation of the network or violates the rules and 365 | protocols for communication across the network. 366 | 367 | Corresponding Source conveyed, and Installation Information provided, 368 | in accord with this section must be in a format that is publicly 369 | documented (and with an implementation available to the public in 370 | source code form), and must require no special password or key for 371 | unpacking, reading or copying. 372 | 373 | 7. Additional Terms. 374 | 375 | "Additional permissions" are terms that supplement the terms of this 376 | License by making exceptions from one or more of its conditions. 377 | Additional permissions that are applicable to the entire Program shall 378 | be treated as though they were included in this License, to the extent 379 | that they are valid under applicable law. If additional permissions 380 | apply only to part of the Program, that part may be used separately 381 | under those permissions, but the entire Program remains governed by 382 | this License without regard to the additional permissions. 383 | 384 | When you convey a copy of a covered work, you may at your option 385 | remove any additional permissions from that copy, or from any part of 386 | it. (Additional permissions may be written to require their own 387 | removal in certain cases when you modify the work.) You may place 388 | additional permissions on material, added by you to a covered work, 389 | for which you have or can give appropriate copyright permission. 390 | 391 | Notwithstanding any other provision of this License, for material you 392 | add to a covered work, you may (if authorized by the copyright holders of 393 | that material) supplement the terms of this License with terms: 394 | 395 | a) Disclaiming warranty or limiting liability differently from the 396 | terms of sections 15 and 16 of this License; or 397 | 398 | b) Requiring preservation of specified reasonable legal notices or 399 | author attributions in that material or in the Appropriate Legal 400 | Notices displayed by works containing it; or 401 | 402 | c) Prohibiting misrepresentation of the origin of that material, or 403 | requiring that modified versions of such material be marked in 404 | reasonable ways as different from the original version; or 405 | 406 | d) Limiting the use for publicity purposes of names of licensors or 407 | authors of the material; or 408 | 409 | e) Declining to grant rights under trademark law for use of some 410 | trade names, trademarks, or service marks; or 411 | 412 | f) Requiring indemnification of licensors and authors of that 413 | material by anyone who conveys the material (or modified versions of 414 | it) with contractual assumptions of liability to the recipient, for 415 | any liability that these contractual assumptions directly impose on 416 | those licensors and authors. 417 | 418 | All other non-permissive additional terms are considered "further 419 | restrictions" within the meaning of section 10. If the Program as you 420 | received it, or any part of it, contains a notice stating that it is 421 | governed by this License along with a term that is a further 422 | restriction, you may remove that term. If a license document contains 423 | a further restriction but permits relicensing or conveying under this 424 | License, you may add to a covered work material governed by the terms 425 | of that license document, provided that the further restriction does 426 | not survive such relicensing or conveying. 427 | 428 | If you add terms to a covered work in accord with this section, you 429 | must place, in the relevant source files, a statement of the 430 | additional terms that apply to those files, or a notice indicating 431 | where to find the applicable terms. 432 | 433 | Additional terms, permissive or non-permissive, may be stated in the 434 | form of a separately written license, or stated as exceptions; 435 | the above requirements apply either way. 436 | 437 | 8. Termination. 438 | 439 | You may not propagate or modify a covered work except as expressly 440 | provided under this License. Any attempt otherwise to propagate or 441 | modify it is void, and will automatically terminate your rights under 442 | this License (including any patent licenses granted under the third 443 | paragraph of section 11). 444 | 445 | However, if you cease all violation of this License, then your 446 | license from a particular copyright holder is reinstated (a) 447 | provisionally, unless and until the copyright holder explicitly and 448 | finally terminates your license, and (b) permanently, if the copyright 449 | holder fails to notify you of the violation by some reasonable means 450 | prior to 60 days after the cessation. 451 | 452 | Moreover, your license from a particular copyright holder is 453 | reinstated permanently if the copyright holder notifies you of the 454 | violation by some reasonable means, this is the first time you have 455 | received notice of violation of this License (for any work) from that 456 | copyright holder, and you cure the violation prior to 30 days after 457 | your receipt of the notice. 458 | 459 | Termination of your rights under this section does not terminate the 460 | licenses of parties who have received copies or rights from you under 461 | this License. If your rights have been terminated and not permanently 462 | reinstated, you do not qualify to receive new licenses for the same 463 | material under section 10. 464 | 465 | 9. Acceptance Not Required for Having Copies. 466 | 467 | You are not required to accept this License in order to receive or 468 | run a copy of the Program. Ancillary propagation of a covered work 469 | occurring solely as a consequence of using peer-to-peer transmission 470 | to receive a copy likewise does not require acceptance. However, 471 | nothing other than this License grants you permission to propagate or 472 | modify any covered work. These actions infringe copyright if you do 473 | not accept this License. Therefore, by modifying or propagating a 474 | covered work, you indicate your acceptance of this License to do so. 475 | 476 | 10. Automatic Licensing of Downstream Recipients. 477 | 478 | Each time you convey a covered work, the recipient automatically 479 | receives a license from the original licensors, to run, modify and 480 | propagate that work, subject to this License. You are not responsible 481 | for enforcing compliance by third parties with this License. 482 | 483 | An "entity transaction" is a transaction transferring control of an 484 | organization, or substantially all assets of one, or subdividing an 485 | organization, or merging organizations. If propagation of a covered 486 | work results from an entity transaction, each party to that 487 | transaction who receives a copy of the work also receives whatever 488 | licenses to the work the party's predecessor in interest had or could 489 | give under the previous paragraph, plus a right to possession of the 490 | Corresponding Source of the work from the predecessor in interest, if 491 | the predecessor has it or can get it with reasonable efforts. 492 | 493 | You may not impose any further restrictions on the exercise of the 494 | rights granted or affirmed under this License. For example, you may 495 | not impose a license fee, royalty, or other charge for exercise of 496 | rights granted under this License, and you may not initiate litigation 497 | (including a cross-claim or counterclaim in a lawsuit) alleging that 498 | any patent claim is infringed by making, using, selling, offering for 499 | sale, or importing the Program or any portion of it. 500 | 501 | 11. Patents. 502 | 503 | A "contributor" is a copyright holder who authorizes use under this 504 | License of the Program or a work on which the Program is based. The 505 | work thus licensed is called the contributor's "contributor version". 506 | 507 | A contributor's "essential patent claims" are all patent claims 508 | owned or controlled by the contributor, whether already acquired or 509 | hereafter acquired, that would be infringed by some manner, permitted 510 | by this License, of making, using, or selling its contributor version, 511 | but do not include claims that would be infringed only as a 512 | consequence of further modification of the contributor version. For 513 | purposes of this definition, "control" includes the right to grant 514 | patent sublicenses in a manner consistent with the requirements of 515 | this License. 516 | 517 | Each contributor grants you a non-exclusive, worldwide, royalty-free 518 | patent license under the contributor's essential patent claims, to 519 | make, use, sell, offer for sale, import and otherwise run, modify and 520 | propagate the contents of its contributor version. 521 | 522 | In the following three paragraphs, a "patent license" is any express 523 | agreement or commitment, however denominated, not to enforce a patent 524 | (such as an express permission to practice a patent or covenant not to 525 | sue for patent infringement). To "grant" such a patent license to a 526 | party means to make such an agreement or commitment not to enforce a 527 | patent against the party. 528 | 529 | If you convey a covered work, knowingly relying on a patent license, 530 | and the Corresponding Source of the work is not available for anyone 531 | to copy, free of charge and under the terms of this License, through a 532 | publicly available network server or other readily accessible means, 533 | then you must either (1) cause the Corresponding Source to be so 534 | available, or (2) arrange to deprive yourself of the benefit of the 535 | patent license for this particular work, or (3) arrange, in a manner 536 | consistent with the requirements of this License, to extend the patent 537 | license to downstream recipients. "Knowingly relying" means you have 538 | actual knowledge that, but for the patent license, your conveying the 539 | covered work in a country, or your recipient's use of the covered work 540 | in a country, would infringe one or more identifiable patents in that 541 | country that you have reason to believe are valid. 542 | 543 | If, pursuant to or in connection with a single transaction or 544 | arrangement, you convey, or propagate by procuring conveyance of, a 545 | covered work, and grant a patent license to some of the parties 546 | receiving the covered work authorizing them to use, propagate, modify 547 | or convey a specific copy of the covered work, then the patent license 548 | you grant is automatically extended to all recipients of the covered 549 | work and works based on it. 550 | 551 | A patent license is "discriminatory" if it does not include within 552 | the scope of its coverage, prohibits the exercise of, or is 553 | conditioned on the non-exercise of one or more of the rights that are 554 | specifically granted under this License. You may not convey a covered 555 | work if you are a party to an arrangement with a third party that is 556 | in the business of distributing software, under which you make payment 557 | to the third party based on the extent of your activity of conveying 558 | the work, and under which the third party grants, to any of the 559 | parties who would receive the covered work from you, a discriminatory 560 | patent license (a) in connection with copies of the covered work 561 | conveyed by you (or copies made from those copies), or (b) primarily 562 | for and in connection with specific products or compilations that 563 | contain the covered work, unless you entered into that arrangement, 564 | or that patent license was granted, prior to 28 March 2007. 565 | 566 | Nothing in this License shall be construed as excluding or limiting 567 | any implied license or other defenses to infringement that may 568 | otherwise be available to you under applicable patent law. 569 | 570 | 12. No Surrender of Others' Freedom. 571 | 572 | If conditions are imposed on you (whether by court order, agreement or 573 | otherwise) that contradict the conditions of this License, they do not 574 | excuse you from the conditions of this License. If you cannot convey a 575 | covered work so as to satisfy simultaneously your obligations under this 576 | License and any other pertinent obligations, then as a consequence you may 577 | not convey it at all. For example, if you agree to terms that obligate you 578 | to collect a royalty for further conveying from those to whom you convey 579 | the Program, the only way you could satisfy both those terms and this 580 | License would be to refrain entirely from conveying the Program. 581 | 582 | 13. Use with the GNU Affero General Public License. 583 | 584 | Notwithstanding any other provision of this License, you have 585 | permission to link or combine any covered work with a work licensed 586 | under version 3 of the GNU Affero General Public License into a single 587 | combined work, and to convey the resulting work. The terms of this 588 | License will continue to apply to the part which is the covered work, 589 | but the special requirements of the GNU Affero General Public License, 590 | section 13, concerning interaction through a network will apply to the 591 | combination as such. 592 | 593 | 14. Revised Versions of this License. 594 | 595 | The Free Software Foundation may publish revised and/or new versions of 596 | the GNU General Public License from time to time. Such new versions will 597 | be similar in spirit to the present version, but may differ in detail to 598 | address new problems or concerns. 599 | 600 | Each version is given a distinguishing version number. If the 601 | Program specifies that a certain numbered version of the GNU General 602 | Public License "or any later version" applies to it, you have the 603 | option of following the terms and conditions either of that numbered 604 | version or of any later version published by the Free Software 605 | Foundation. If the Program does not specify a version number of the 606 | GNU General Public License, you may choose any version ever published 607 | by the Free Software Foundation. 608 | 609 | If the Program specifies that a proxy can decide which future 610 | versions of the GNU General Public License can be used, that proxy's 611 | public statement of acceptance of a version permanently authorizes you 612 | to choose that version for the Program. 613 | 614 | Later license versions may give you additional or different 615 | permissions. However, no additional obligations are imposed on any 616 | author or copyright holder as a result of your choosing to follow a 617 | later version. 618 | 619 | 15. Disclaimer of Warranty. 620 | 621 | THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY 622 | APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT 623 | HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY 624 | OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, 625 | THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR 626 | PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM 627 | IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF 628 | ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 629 | 630 | 16. Limitation of Liability. 631 | 632 | IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 633 | WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS 634 | THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY 635 | GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE 636 | USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF 637 | DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD 638 | PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), 639 | EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF 640 | SUCH DAMAGES. 641 | 642 | 17. Interpretation of Sections 15 and 16. 643 | 644 | If the disclaimer of warranty and limitation of liability provided 645 | above cannot be given local legal effect according to their terms, 646 | reviewing courts shall apply local law that most closely approximates 647 | an absolute waiver of all civil liability in connection with the 648 | Program, unless a warranty or assumption of liability accompanies a 649 | copy of the Program in return for a fee. 650 | 651 | END OF TERMS AND CONDITIONS 652 | 653 | How to Apply These Terms to Your New Programs 654 | 655 | If you develop a new program, and you want it to be of the greatest 656 | possible use to the public, the best way to achieve this is to make it 657 | free software which everyone can redistribute and change under these terms. 658 | 659 | To do so, attach the following notices to the program. It is safest 660 | to attach them to the start of each source file to most effectively 661 | state the exclusion of warranty; and each file should have at least 662 | the "copyright" line and a pointer to where the full notice is found. 663 | 664 | {one line to give the program's name and a brief idea of what it does.} 665 | Copyright (C) {year} {name of author} 666 | 667 | This program is free software: you can redistribute it and/or modify 668 | it under the terms of the GNU General Public License as published by 669 | the Free Software Foundation, either version 3 of the License, or 670 | (at your option) any later version. 671 | 672 | This program is distributed in the hope that it will be useful, 673 | but WITHOUT ANY WARRANTY; without even the implied warranty of 674 | MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the 675 | GNU General Public License for more details. 676 | 677 | You should have received a copy of the GNU General Public License 678 | along with this program. If not, see . 679 | 680 | Also add information on how to contact you by electronic and paper mail. 681 | 682 | If the program does terminal interaction, make it output a short 683 | notice like this when it starts in an interactive mode: 684 | 685 | {project} Copyright (C) {year} {fullname} 686 | This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. 687 | This is free software, and you are welcome to redistribute it 688 | under certain conditions; type `show c' for details. 689 | 690 | The hypothetical commands `show w' and `show c' should show the appropriate 691 | parts of the General Public License. Of course, your program's commands 692 | might be different; for a GUI interface, you would use an "about box". 693 | 694 | You should also get your employer (if you work as a programmer) or school, 695 | if any, to sign a "copyright disclaimer" for the program, if necessary. 696 | For more information on this, and how to apply and follow the GNU GPL, see 697 | . 698 | 699 | The GNU General Public License does not permit incorporating your program 700 | into proprietary programs. If your program is a subroutine library, you 701 | may consider it more useful to permit linking proprietary applications with 702 | the library. If this is what you want to do, use the GNU Lesser General 703 | Public License instead of this License. But first, please read 704 | . 705 | 706 | ### quic-go 707 | 708 | https://github.com/lucas-clemente/quic-go 709 | 710 | MIT License 711 | 712 | Copyright (c) 2016 the quic-go authors & Google, Inc. 713 | 714 | Permission is hereby granted, free of charge, to any person obtaining a copy 715 | of this software and associated documentation files (the "Software"), to deal 716 | in the Software without restriction, including without limitation the rights 717 | to use, copy, modify, merge, publish, distribute, sublicense, and/or sell 718 | copies of the Software, and to permit persons to whom the Software is 719 | furnished to do so, subject to the following conditions: 720 | 721 | The above copyright notice and this permission notice shall be included in all 722 | copies or substantial portions of the Software. 723 | 724 | THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR 725 | IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, 726 | FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
