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 | 635 | Copyright (C) 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 | Copyright (C) 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 | -------------------------------------------------------------------------------- /README.md: -------------------------------------------------------------------------------- 1 | # k8s-debugbox 2 | 3 | k8s-debugbox is a tool for debugging Kubernetes pods based on minimal images. 4 | It works by copying statically linked tools, including a shell, into the pods you want to debug. 5 | 6 | ## Requirements 7 | 8 | Kubernetes cluster: 9 | * k8s-debugbox has no special requirements towards Kubernetes clusters 10 | 11 | Client: 12 | * Bash 3 or later 13 | * [kubectl (Kubernetes client)](https://kubernetes.io/docs/tasks/tools/install-kubectl/) or [oc (OpenShift client)](https://docs.okd.io/latest/cli_reference/get_started_cli.html) 14 | 15 | Most modern operating systems already come with Bash 3 or later. However on Windows you have to get it by either installing the full version of [Cmdr](http://cmder.net/) or [Windows Subsystem for Linux](https://docs.microsoft.com/en-us/windows/wsl/install-win10) (Windows 10 only). 16 | 17 | ## Installation 18 | 19 | 1. Download a [k8s-debugbox release](https://github.com/puzzle/k8s-debugbox/releases) 20 | 2. Extract the downloaded file 21 | 3. Change into the created directory 22 | 4. Run `install.sh` (`install.bat` on Windows) 23 | 24 | ## Usage 25 | 26 | ```sh 27 | $ k8s-debugbox --help 28 | Debug pods based on minimal images. 29 | 30 | Examples: 31 | # Open debugging shell for the first container of the specified pod, 32 | # install debugging tools into the container if they aren't installed yet. 33 | k8s-debugbox pod hello-42-dmj88 34 | 35 | # Open debugging shell for container 'proxy' of the specified pod, 36 | # install debugging tools into the container if they aren't installed yet. 37 | k8s-debugbox pod hello-42-dmj88 -c proxy 38 | 39 | # Install debugging tools into specified pod. 40 | k8s-debugbox pod hello-42-dmj88 --add 41 | 42 | # Uninstall debugging tools from specified pod. 43 | k8s-debugbox pod hello-42-dmj88 --remove 44 | 45 | # Open debugging shell for the first container of the first pod of the specified controller, 46 | # install debugging tools into all containers of the controller if they aren't installed yet. 47 | # Requires a redeployment. 48 | k8s-debugbox deployment hello 49 | 50 | # Open debugging shell for the first container of the first pod of the specified controller, 51 | # install debugging tools into all containers of the controller if they aren't installed yet. 52 | # Uses the specified Docker image for tool installation instead of the default one. 53 | # Requires a redeployment. 54 | k8s-debugbox deployment hello -i example.org/tools/k8s-debugbox 55 | 56 | # Uninstall debugging tools from specified controller. 57 | # Requires a redeployment. 58 | k8s-debugbox deployment hello --remove 59 | 60 | Options: 61 | -n, --namespace='': Namespace which contains the pod to debug, defaults to the namespace of the current kubectl context 62 | -c, --container='': Container name to open shell for, defaults to first container in pod 63 | -i, --image='puzzle/k8s-debugbox': Docker image for installation of debugging via controller.

By contrast, the GNU General Public 21 | License is intended to guarantee your freedom to share and change free 22 | software--to make sure the software is free for all its users. This 23 | General Public License applies to most of the Free Software 24 | Foundation's software and to any other program whose authors commit to 25 | using it. (Some other Free Software Foundation software is covered by 26 | the GNU Library General Public License instead.) You can apply it to 27 | your programs, too. 28 | 29 | When we speak of free software, we are referring to freedom, not 30 | price. Our General Public Licenses are designed to make sure that you 31 | have the freedom to distribute copies of free software (and charge for 32 | this service if you wish), that you receive source code or can get it 33 | if you want it, that you can change the software or use pieces of it 34 | in new free programs; and that you know you can do these things. 35 | 36 | To protect your rights, we need to make restrictions that forbid 37 | anyone to deny you these rights or to ask you to surrender the rights. 38 | These restrictions translate to certain responsibilities for you if you 39 | distribute copies of the software, or if you modify it. 40 | 41 | For example, if you distribute copies of such a program, whether 42 | gratis or for a fee, you must give the recipients all the rights that 43 | you have. You must make sure that they, too, receive or can get the 44 | source code. And you must show them these terms so they know their 45 | rights. 46 | 47 | We protect your rights with two steps: (1) copyright the software, and 48 | (2) offer you this license which gives you legal permission to copy, 49 | distribute and/or modify the software. 50 | 51 | Also, for each author's protection and ours, we want to make certain 52 | that everyone understands that there is no warranty for this free 53 | software. If the software is modified by someone else and passed on, we 54 | want its recipients to know that what they have is not the original, so 55 | that any problems introduced by others will not reflect on the original 56 | authors' reputations. 57 | 58 | Finally, any free program is threatened constantly by software 59 | patents. We wish to avoid the danger that redistributors of a free 60 | program will individually obtain patent licenses, in effect making the 61 | program proprietary. To prevent this, we have made it clear that any 62 | patent must be licensed for everyone's free use or not licensed at all. 63 | 64 | The precise terms and conditions for copying, distribution and 65 | modification follow. 66 | 67 | GNU GENERAL PUBLIC LICENSE 68 | TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 69 | 70 | 0. This License applies to any program or other work which contains 71 | a notice placed by the copyright holder saying it may be distributed 72 | under the terms of this General Public License. The "Program", below, 73 | refers to any such program or work, and a "work based on the Program" 74 | means either the Program or any derivative work under copyright law: 75 | that is to say, a work containing the Program or a portion of it, 76 | either verbatim or with modifications and/or translated into another 77 | language. (Hereinafter, translation is included without limitation in 78 | the term "modification".) Each licensee is addressed as "you". 79 | 80 | Activities other than copying, distribution and modification are not 81 | covered by this License; they are outside its scope. The act of 82 | running the Program is not restricted, and the output from the Program 83 | is covered only if its contents constitute a work based on the 84 | Program (independent of having been made by running the Program). 85 | Whether that is true depends on what the Program does. 86 | 87 | 1. You may copy and distribute verbatim copies of the Program's 88 | source code as you receive it, in any medium, provided that you 89 | conspicuously and appropriately publish on each copy an appropriate 90 | copyright notice and disclaimer of warranty; keep intact all the 91 | notices that refer to this License and to the absence of any warranty; 92 | and give any other recipients of the Program a copy of this License 93 | along with the Program. 94 | 95 | You may charge a fee for the physical act of transferring a copy, and 96 | you may at your option offer warranty protection in exchange for a fee. 97 | 98 | 2. You may modify your copy or copies of the Program or any portion 99 | of it, thus forming a work based on the Program, and copy and 100 | distribute such modifications or work under the terms of Section 1 101 | above, provided that you also meet all of these conditions: 102 | 103 | a) You must cause the modified files to carry prominent notices 104 | stating that you changed the files and the date of any change. 105 | 106 | b) You must cause any work that you distribute or publish, that in 107 | whole or in part contains or is derived from the Program or any 108 | part thereof, to be licensed as a whole at no charge to all third 109 | parties under the terms of this License. 110 | 111 | c) If the modified program normally reads commands interactively 112 | when run, you must cause it, when started running for such 113 | interactive use in the most ordinary way, to print or display an 114 | announcement including an appropriate copyright notice and a 115 | notice that there is no warranty (or else, saying that you provide 116 | a warranty) and that users may redistribute the program under 117 | these conditions, and telling the user how to view a copy of this 118 | License. (Exception: if the Program itself is interactive but 119 | does not normally print such an announcement, your work based on 120 | the Program is not required to print an announcement.) 121 | 122 | These requirements apply to the modified work as a whole. If 123 | identifiable sections of that work are not derived from the Program, 124 | and can be reasonably considered independent and separate works in 125 | themselves, then this License, and its terms, do not apply to those 126 | sections when you distribute them as separate works. But when you 127 | distribute the same sections as part of a whole which is a work based 128 | on the Program, the distribution of the whole must be on the terms of 129 | this License, whose permissions for other licensees extend to the 130 | entire whole, and thus to each and every part regardless of who wrote it. 131 | 132 | Thus, it is not the intent of this section to claim rights or contest 133 | your rights to work written entirely by you; rather, the intent is to 134 | exercise the right to control the distribution of derivative or 135 | collective works based on the Program. 136 | 137 | In addition, mere aggregation of another work not based on the Program 138 | with the Program (or with a work based on the Program) on a volume of 139 | a storage or distribution medium does not bring the other work under 140 | the scope of this License. 141 | 142 | 3. You may copy and distribute the Program (or a work based on it, 143 | under Section 2) in object code or executable form under the terms of 144 | Sections 1 and 2 above provided that you also do one of the following: 145 | 146 | a) Accompany it with the complete corresponding machine-readable 147 | source code, which must be distributed under the terms of Sections 148 | 1 and 2 above on a medium customarily used for software interchange; or, 149 | 150 | b) Accompany it with a written offer, valid for at least three 151 | years, to give any third party, for a charge no more than your 152 | cost of physically performing source distribution, a complete 153 | machine-readable copy of the corresponding source code, to be 154 | distributed under the terms of Sections 1 and 2 above on a medium 155 | customarily used for software interchange; or, 156 | 157 | c) Accompany it with the information you received as to the offer 158 | to distribute corresponding source code. (This alternative is 159 | allowed only for noncommercial distribution and only if you 160 | received the program in object code or executable form with such 161 | an offer, in accord with Subsection b above.) 162 | 163 | The source code for a work means the preferred form of the work for 164 | making modifications to it. For an executable work, complete source 165 | code means all the source code for all modules it contains, plus any 166 | associated interface definition files, plus the scripts used to 167 | control compilation and installation of the executable. However, as a 168 | special exception, the source code distributed need not include 169 | anything that is normally distributed (in either source or binary 170 | form) with the major components (compiler, kernel, and so on) of the 171 | operating system on which the executable runs, unless that component 172 | itself accompanies the executable. 173 | 174 | If distribution of executable or object code is made by offering 175 | access to copy from a designated place, then offering equivalent 176 | access to copy the source code from the same place counts as 177 | distribution of the source code, even though third parties are not 178 | compelled to copy the source along with the object code. 179 | 180 | 4. You may not copy, modify, sublicense, or distribute the Program 181 | except as expressly provided under this License. Any attempt 182 | otherwise to copy, modify, sublicense or distribute the Program is 183 | void, and will automatically terminate your rights under this License. 184 | However, parties who have received copies, or rights, from you under 185 | this License will not have their licenses terminated so long as such 186 | parties remain in full compliance. 187 | 188 | 5. You are not required to accept this License, since you have not 189 | signed it. However, nothing else grants you permission to modify or 190 | distribute the Program or its derivative works. These actions are 191 | prohibited by law if you do not accept this License. Therefore, by 192 | modifying or distributing the Program (or any work based on the 193 | Program), you indicate your acceptance of this License to do so, and 194 | all its terms and conditions for copying, distributing or modifying 195 | the Program or works based on it. 196 | 197 | 6. Each time you redistribute the Program (or any work based on the 198 | Program), the recipient automatically receives a license from the 199 | original licensor to copy, distribute or modify the Program subject to 200 | these terms and conditions. You may not impose any further 201 | restrictions on the recipients' exercise of the rights granted herein. 202 | You are not responsible for enforcing compliance by third parties to 203 | this License. 204 | 205 | 7. If, as a consequence of a court judgment or allegation of patent 206 | infringement or for any other reason (not limited to patent issues), 207 | conditions are imposed on you (whether by court order, agreement or 208 | otherwise) that contradict the conditions of this License, they do not 209 | excuse you from the conditions of this License. If you cannot 210 | distribute so as to satisfy simultaneously your obligations under this 211 | License and any other pertinent obligations, then as a consequence you 212 | may not distribute the Program at all. For example, if a patent 213 | license would not permit royalty-free redistribution of the Program by 214 | all those who receive copies directly or indirectly through you, then 215 | the only way you could satisfy both it and this License would be to 216 | refrain entirely from distribution of the Program. 217 | 218 | If any portion of this section is held invalid or unenforceable under 219 | any particular circumstance, the balance of the section is intended to 220 | apply and the section as a whole is intended to apply in other 221 | circumstances. 222 | 223 | It is not the purpose of this section to induce you to infringe any 224 | patents or other property right claims or to contest validity of any 225 | such claims; this section has the sole purpose of protecting the 226 | integrity of the free software distribution system, which is 227 | implemented by public license practices. Many people have made 228 | generous contributions to the wide range of software distributed 229 | through that system in reliance on consistent application of that 230 | system; it is up to the author/donor to decide if he or she is willing 231 | to distribute software through any other system and a licensee cannot 232 | impose that choice. 233 | 234 | This section is intended to make thoroughly clear what is believed to 235 | be a consequence of the rest of this License. 236 | 237 | 8. If the distribution and/or use of the Program is restricted in 238 | certain countries either by patents or by copyrighted interfaces, the 239 | original copyright holder who places the Program under this License 240 | may add an explicit geographical distribution limitation excluding 241 | those countries, so that distribution is permitted only in or among 242 | countries not thus excluded. In such case, this License incorporates 243 | the limitation as if written in the body of this License. 244 | 245 | 9. The Free Software Foundation may publish revised and/or new versions 246 | of the General Public License from time to time. Such new versions will 247 | be similar in spirit to the present version, but may differ in detail to 248 | address new problems or concerns. 249 | 250 | Each version is given a distinguishing version number. If the Program 251 | specifies a version number of this License which applies to it and "any 252 | later version", you have the option of following the terms and conditions 253 | either of that version or of any later version published by the Free 254 | Software Foundation. If the Program does not specify a version number of 255 | this License, you may choose any version ever published by the Free Software 256 | Foundation. 257 | 258 | 10. If you wish to incorporate parts of the Program into other free 259 | programs whose distribution conditions are different, write to the author 260 | to ask for permission. For software which is copyrighted by the Free 261 | Software Foundation, write to the Free Software Foundation; we sometimes 262 | make exceptions for this. Our decision will be guided by the two goals 263 | of preserving the free status of all derivatives of our free software and 264 | of promoting the sharing and reuse of software generally. 265 | 266 | NO WARRANTY 267 | 268 | 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY 269 | FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN 270 | OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES 271 | PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED 272 | OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF 273 | MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS 274 | TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE 275 | PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, 276 | REPAIR OR CORRECTION. 277 | 278 | 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 279 | WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR 280 | REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, 281 | INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING 282 | OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED 283 | TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY 284 | YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER 285 | PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE 286 | POSSIBILITY OF SUCH DAMAGES. 287 | 288 | END OF TERMS AND CONDITIONS 289 | 290 | How to Apply These Terms to Your New Programs 291 | 292 | If you develop a new program, and you want it to be of the greatest 293 | possible use to the public, the best way to achieve this is to make it 294 | free software which everyone can redistribute and change under these terms. 295 | 296 | To do so, attach the following notices to the program. It is safest 297 | to attach them to the start of each source file to most effectively 298 | convey the exclusion of warranty; and each file should have at least 299 | the "copyright" line and a pointer to where the full notice is found. 300 | 301 | 302 | Copyright (C) 303 | 304 | This program is free software; you can redistribute it and/or modify 305 | it under the terms of the GNU General Public License as published by 306 | the Free Software Foundation; either version 2 of the License, or 307 | (at your option) any later version. 308 | 309 | This program is distributed in the hope that it will be useful, 310 | but WITHOUT ANY WARRANTY; without even the implied warranty of 311 | MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the 312 | GNU General Public License for more details. 313 | 314 | You should have received a copy of the GNU General Public License 315 | along with this program; if not, write to the Free Software 316 | Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA 317 | 318 | 319 | Also add information on how to contact you by electronic and paper mail. 320 | 321 | If the program is interactive, make it output a short notice like this 322 | when it starts in an interactive mode: 323 | 324 | Gnomovision version 69, Copyright (C) year name of author 325 | Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. 326 | This is free software, and you are welcome to redistribute it 327 | under certain conditions; type `show c' for details. 328 | 329 | The hypothetical commands `show w' and `show c' should show the appropriate 330 | parts of the General Public License. Of course, the commands you use may 331 | be called something other than `show w' and `show c'; they could even be 332 | mouse-clicks or menu items--whatever suits your program. 333 | 334 | You should also get your employer (if you work as a programmer) or your 335 | school, if any, to sign a "copyright disclaimer" for the program, if 336 | necessary. Here is a sample; alter the names: 337 | 338 | Yoyodyne, Inc., hereby disclaims all copyright interest in the program 339 | `Gnomovision' (which makes passes at compilers) written by James Hacker. 340 | 341 | , 1 April 1989 342 | Ty Coon, President of Vice 343 | 344 | This General Public License does not permit incorporating your program into 345 | proprietary programs.

You can use and copy it as much as you like, but you are 11 | encouraged to make a donation for needy children in Uganda. Please see |kcc| 12 | below or visit the ICCF web site, available at these URLs: 13 | 14 | http://iccf-holland.org/ 15 | http://www.vim.org/iccf/ 16 | http://www.iccf.nl/ 17 | 18 | You can also sponsor the development of Vim. Vim sponsors can vote for 19 | features. See |sponsor|. The money goes to Uganda anyway. 20 | 21 | The Open Publication License applies to the Vim documentation, see 22 | |manual-copyright|. 23 | 24 | === begin of license === 25 | 26 | VIM LICENSE 27 | 28 | I) There are no restrictions on distributing unmodified copies of Vim except 29 | that they must include this license text. You can also distribute 30 | unmodified parts of Vim, likewise unrestricted except that they must 31 | include this license text. You are also allowed to include executables 32 | that you made from the unmodified Vim sources, plus your own usage 33 | examples and Vim scripts. 34 | 35 | II) It is allowed to distribute a modified (or extended) version of Vim, 36 | including executables and/or source code, when the following four 37 | conditions are met: 38 | 1) This license text must be included unmodified. 39 | 2) The modified Vim must be distributed in one of the following five ways: 40 | a) If you make changes to Vim yourself, you must clearly describe in 41 | the distribution how to contact you. When the maintainer asks you 42 | (in any way) for a copy of the modified Vim you distributed, you 43 | must make your changes, including source code, available to the 44 | maintainer without fee. The maintainer reserves the right to 45 | include your changes in the official version of Vim. What the 46 | maintainer will do with your changes and under what license they 47 | will be distributed is negotiable. If there has been no negotiation 48 | then this license, or a later version, also applies to your changes. 49 | The current maintainer is Bram Moolenaar . If this 50 | changes it will be announced in appropriate places (most likely 51 | vim.sf.net, www.vim.org and/or comp.editors). When it is completely 52 | impossible to contact the maintainer, the obligation to send him 53 | your changes ceases. Once the maintainer has confirmed that he has 54 | received your changes they will not have to be sent again. 55 | b) If you have received a modified Vim that was distributed as 56 | mentioned under a) you are allowed to further distribute it 57 | unmodified, as mentioned at I). If you make additional changes the 58 | text under a) applies to those changes. 59 | c) Provide all the changes, including source code, with every copy of 60 | the modified Vim you distribute. This may be done in the form of a 61 | context diff. You can choose what license to use for new code you 62 | add. The changes and their license must not restrict others from 63 | making their own changes to the official version of Vim. 64 | d) When you have a modified Vim which includes changes as mentioned 65 | under c), you can distribute it without the source code for the 66 | changes if the following three conditions are met: 67 | - The license that applies to the changes permits you to distribute 68 | the changes to the Vim maintainer without fee or restriction, and 69 | permits the Vim maintainer to include the changes in the official 70 | version of Vim without fee or restriction. 71 | - You keep the changes for at least three years after last 72 | distributing the corresponding modified Vim. When the maintainer 73 | or someone who you distributed the modified Vim to asks you (in 74 | any way) for the changes within this period, you must make them 75 | available to him. 76 | - You clearly describe in the distribution how to contact you. This 77 | contact information must remain valid for at least three years 78 | after last distributing the corresponding modified Vim, or as long 79 | as possible. 80 | e) When the GNU General Public License (GPL) applies to the changes, 81 | you can distribute the modified Vim under the GNU GPL version 2 or 82 | any later version. 83 | 3) A message must be added, at least in the output of the ":version" 84 | command and in the intro screen, such that the user of the modified Vim 85 | is able to see that it was modified. When distributing as mentioned 86 | under 2)e) adding the message is only required for as far as this does 87 | not conflict with the license used for the changes. 88 | 4) The contact information as required under 2)a) and 2)d) must not be 89 | removed or changed, except that the person himself can make 90 | corrections. 91 | 92 | III) If you distribute a modified version of Vim, you are encouraged to use 93 | the Vim license for your changes and make them available to the 94 | maintainer, including the source code. The preferred way to do this is 95 | by e-mail or by uploading the files to a server and e-mailing the URL. 96 | If the number of changes is small (e.g., a modified Makefile) e-mailing a 97 | context diff will do. The e-mail address to be used is 98 | 99 | 100 | IV) It is not allowed to remove this license from the distribution of the Vim 101 | sources, parts of it or from a modified version. You may use this 102 | license for previous Vim releases instead of the license that they came 103 | with, at your option. 104 | 105 | === end of license === 106 | 107 | Note: 108 | 109 | - If you are happy with Vim, please express that by reading the rest of this 110 | file and consider helping needy children in Uganda. 111 | 112 | - If you want to support further Vim development consider becoming a 113 | |sponsor|. The money goes to Uganda anyway. 114 | 115 | - According to Richard Stallman the Vim license is GNU GPL compatible. 116 | A few minor changes have been made since he checked it, but that should not 117 | make a difference. 118 | 119 | - If you link Vim with a library that goes under the GNU GPL, this limits 120 | further distribution to the GNU GPL. Also when you didn't actually change 121 | anything in Vim. 122 | 123 | - Once a change is included that goes under the GNU GPL, this forces all 124 | further changes to also be made under the GNU GPL or a compatible license. 125 | 126 | - If you distribute a modified version of Vim, you can include your name and 127 | contact information with the "--with-modified-by" configure argument or the 128 | MODIFIED_BY define. 129 | 130 | ============================================================================== 131 | Kibaale Children's Centre *kcc* *Kibaale* *charity* 132 | 133 | Kibaale Children's Centre (KCC) is located in Kibaale, a small town in the 134 | south of Uganda, near Tanzania, in East Africa. The area is known as Rakai 135 | District. The population is mostly farmers. Although people are poor, there 136 | is enough food. But this district is suffering from AIDS more than any other 137 | part of the world. Some say that it started there. Estimations are that 10 138 | to 30% of the Ugandans are infected with HIV. Because parents die, there are 139 | many orphans. In this district about 60,000 children have lost one or both 140 | parents, out of a population of 350,000. And this is still continuing. 141 | 142 | The children need a lot of help. The KCC is working hard to provide the needy 143 | with food, medical care and education. Food and medical care to keep them 144 | healthy now, and education so that they can take care of themselves in the 145 | future. KCC works on a Christian base, but help is given to children of any 146 | religion. 147 | 148 | The key to solving the problems in this area is education. This has been 149 | neglected in the past years with president Idi Amin and the following civil 150 | wars. Now that the government is stable again, the children and parents have 151 | to learn how to take care of themselves and how to avoid infections. There is 152 | also help for people who are ill and hungry, but the primary goal is to 153 | prevent people from getting ill and to teach them how to grow healthy food. 154 | 155 | Most of the orphans are living in an extended family. An uncle or older 156 | sister is taking care of them. Because these families are big and the income 157 | (if any) is low, a child is lucky if it gets healthy food. Clothes, medical 158 | care and schooling is beyond its reach. To help these needy children, a 159 | sponsorship program was put into place. A child can be financially adopted. 160 | For a few dollars a month KCC sees to it that the child gets indispensable 161 | items, is healthy, goes to school and KCC takes care of anything else that 162 | needs to be done for the child and the family that supports it. 163 | 164 | Besides helping the child directly, the environment where the child grows up 165 | needs to be improved. KCC helps schools to improve their teaching methods. 166 | There is a demonstration school at the centre and teacher trainings are given. 167 | Health workers are being trained, hygiene education is carried out and 168 | households are stimulated to build a proper latrine. I helped setting up a 169 | production site for cement slabs. These are used to build a good latrine. 170 | They are sold below cost price. 171 | 172 | There is a small clinic at the project, which provides children and their 173 | family with medical help. When needed, transport to a hospital is offered. 174 | Immunization programs are carried out and help is provided when an epidemic is 175 | breaking out (measles and cholera have been a problem). 176 | *donate* 177 | Summer 1994 to summer 1995 I spent a whole year at the centre, working as a 178 | volunteer. I have helped to expand the centre and worked in the area of water 179 | and sanitation. I learned that the help that the KCC provides really helps. 180 | When I came back to Holland, I wanted to continue supporting KCC. To do this 181 | I'm raising funds and organizing the sponsorship program. Please consider one 182 | of these possibilities: 183 | 184 | 1. Sponsor a child in primary school: 17 euro a month (or more). 185 | 2. Sponsor a child in secondary school: 25 euro a month (or more). 186 | 3. Sponsor the clinic: Any amount a month or quarter 187 | 4. A one-time donation 188 | 189 | Compared with other organizations that do child sponsorship the amounts are 190 | very low. This is because the money goes directly to the centre. Less than 191 | 5% is used for administration. This is possible because this is a small 192 | organization that works with volunteers. If you would like to sponsor a 193 | child, you should have the intention to do this for at least one year. 194 | 195 | How do you know that the money will be spent right? First of all you have my 196 | personal guarantee as the author of Vim. I trust the people that are working 197 | at the centre, I know them personally. Furthermore, the centre has been 198 | co-sponsored and inspected by World Vision, Save the Children Fund and is now 199 | under the supervision of Pacific Academy Outreach Society. The centre is 200 | visited about once a year to check the progress (at our own cost). I have 201 | visited the centre myself many times, starting in 1993. The visit reports are 202 | on the ICCF web site. 203 | 204 | If you have any further questions, send me e-mail: . 205 | 206 | The address of the centre is: 207 | Kibaale Children's Centre 208 | p.o. box 1658 209 | Masaka, Uganda, East Africa 210 | 211 | Sending money: *iccf-donations* 212 | 213 | Check the ICCF web site for the latest information! See |iccf| for the URL. 214 | 215 | 216 | USA: The methods mentioned below can be used. 217 | Sending a check to the Nehemiah Group Outreach Society (NGOS) 218 | is no longer possible, unfortunately. We are looking for 219 | another way to get you an IRS tax receipt. 220 | For sponsoring a child contact KCF in Canada (see below). US 221 | checks can be sent to them to lower banking costs. 222 | 223 | Canada: Contact Kibaale Children's Fund (KCF) in Surrey, Canada. They 224 | take care of the Canadian sponsors for the children in 225 | Kibaale. KCF forwards 100% of the money to the project in 226 | Uganda. You can send them a one time donation directly. 227 | Please send me a note so that I know what has been donated 228 | because of Vim. Ask KCF for information about sponsorship. 229 | Kibaale Children's Fund c/o Pacific Academy 230 | 10238-168 Street 231 | Surrey, B.C.

Use Euro for the 250 | currency if possible. 251 | 252 | Europe: Use a bank transfer if possible. Your bank should have a form 253 | that you can use for this. See "Others" below for the swift 254 | code and IBAN number. 255 | Any other method should work. Ask for information about 256 | sponsorship. 257 | 258 | Credit Card: You can use PayPal to send money with a Credit card. This is 259 | the most widely used Internet based payment system.
