1 **************************************************************** 2 3 Notice: Most of LinuxCNC is covered by the GNU General Public 4 License. Some portions are covered by the GNU Lesser 5 General Public License (mostly interface definitions). 6 Both licenses are included in their entirety below. 7 8 Much of LinuxCNC is derived from the Enhanced Machine Controller, a 9 work of Fred Proctor, Tom Kramer, Will Shackleford, and others. 10 That work was originally released into the public domain. It was 11 used as the basis of LinuxCNC, but received extensive modifications. 12 LinuxCNC is NOT public domain. Anyone wishing to use the public 13 domain code in a way that is not compatible with the (L)GPL must 14 locate the original the Enhanced Machine Controller code - they may 15 NOT use LinuxCNC. 16 17 ****************************************************************** 18 19 GNU GENERAL PUBLIC LICENSE 20 Version 2, June 1991 21 22 Copyright (C) 1989, 1991 Free Software Foundation, Inc., 23 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA 24 Everyone is permitted to copy and distribute verbatim copies 25 of this license document, but changing it is not allowed. 26 27 Preamble 28 29 The licenses for most software are designed to take away your 30 freedom to share and change it. By contrast, the GNU General Public 31 License is intended to guarantee your freedom to share and change free 32 software--to make sure the software is free for all its users. This 33 General Public License applies to most of the Free Software 34 Foundation's software and to any other program whose authors commit to 35 using it. (Some other Free Software Foundation software is covered by 36 the GNU Library General Public License instead.) You can apply it to 37 your programs, too. 38 39 When we speak of free software, we are referring to freedom, not 40 price. Our General Public Licenses are designed to make sure that you 41 have the freedom to distribute copies of free software (and charge for 42 this service if you wish), that you receive source code or can get it 43 if you want it, that you can change the software or use pieces of it 44 in new free programs; and that you know you can do these things. 45 46 To protect your rights, we need to make restrictions that forbid 47 anyone to deny you these rights or to ask you to surrender the rights. 48 These restrictions translate to certain responsibilities for you if you 49 distribute copies of the software, or if you modify it. 50 51 For example, if you distribute copies of such a program, whether 52 gratis or for a fee, you must give the recipients all the rights that 53 you have. You must make sure that they, too, receive or can get the 54 source code. And you must show them these terms so they know their 55 rights. 56 57 We protect your rights with two steps: (1) copyright the software, and 58 (2) offer you this license which gives you legal permission to copy, 59 distribute and/or modify the software. 60 61 Also, for each author's protection and ours, we want to make certain 62 that everyone understands that there is no warranty for this free 63 software. If the software is modified by someone else and passed on, we 64 want its recipients to know that what they have is not the original, so 65 that any problems introduced by others will not reflect on the original 66 authors' reputations. 67 68 Finally, any free program is threatened constantly by software 69 patents. We wish to avoid the danger that redistributors of a free 70 program will individually obtain patent licenses, in effect making the 71 program proprietary. To prevent this, we have made it clear that any 72 patent must be licensed for everyone's free use or not licensed at all. 73 74 The precise terms and conditions for copying, distribution and 75 modification follow. 76 77 GNU GENERAL PUBLIC LICENSE 78 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 79 80 0. This License applies to any program or other work which contains 81 a notice placed by the copyright holder saying it may be distributed 82 under the terms of this General Public License. The "Program", below, 83 refers to any such program or work, and a "work based on the Program" 84 means either the Program or any derivative work under copyright law: 85 that is to say, a work containing the Program or a portion of it, 86 either verbatim or with modifications and/or translated into another 87 language. (Hereinafter, translation is included without limitation in 88 the term "modification".) Each licensee is addressed as "you". 89 90 Activities other than copying, distribution and modification are not 91 covered by this License; they are outside its scope. The act of 92 running the Program is not restricted, and the output from the Program 93 is covered only if its contents constitute a work based on the 94 Program (independent of having been made by running the Program). 95 Whether that is true depends on what the Program does. 96 97 1. You may copy and distribute verbatim copies of the Program's 98 source code as you receive it, in any medium, provided that you 99 conspicuously and appropriately publish on each copy an appropriate 100 copyright notice and disclaimer of warranty; keep intact all the 101 notices that refer to this License and to the absence of any warranty; 102 and give any other recipients of the Program a copy of this License 103 along with the Program. 104 105 You may charge a fee for the physical act of transferring a copy, and 106 you may at your option offer warranty protection in exchange for a fee. 107 108 2. You may modify your copy or copies of the Program or any portion 109 of it, thus forming a work based on the Program, and copy and 110 distribute such modifications or work under the terms of Section 1 111 above, provided that you also meet all of these conditions: 112 113 a) You must cause the modified files to carry prominent notices 114 stating that you changed the files and the date of any change. 115 116 b) You must cause any work that you distribute or publish, that in 117 whole or in part contains or is derived from the Program or any 118 part thereof, to be licensed as a whole at no charge to all third 119 parties under the terms of this License. 120 121 c) If the modified program normally reads commands interactively 122 when run, you must cause it, when started running for such 123 interactive use in the most ordinary way, to print or display an 124 announcement including an appropriate copyright notice and a 125 notice that there is no warranty (or else, saying that you provide 126 a warranty) and that users may redistribute the program under 127 these conditions, and telling the user how to view a copy of this 128 License. (Exception: if the Program itself is interactive but 129 does not normally print such an announcement, your work based on 130 the Program is not required to print an announcement.) 131 132 These requirements apply to the modified work as a whole. If 133 identifiable sections of that work are not derived from the Program, 134 and can be reasonably considered independent and separate works in 135 themselves, then this License, and its terms, do not apply to those 136 sections when you distribute them as separate works. But when you 137 distribute the same sections as part of a whole which is a work based 138 on the Program, the distribution of the whole must be on the terms of 139 this License, whose permissions for other licensees extend to the 140 entire whole, and thus to each and every part regardless of who wrote it. 141 142 Thus, it is not the intent of this section to claim rights or contest 143 your rights to work written entirely by you; rather, the intent is to 144 exercise the right to control the distribution of derivative or 145 collective works based on the Program. 146 147 In addition, mere aggregation of another work not based on the Program 148 with the Program (or with a work based on the Program) on a volume of 149 a storage or distribution medium does not bring the other work under 150 the scope of this License. 151 152 3. You may copy and distribute the Program (or a work based on it, 153 under Section 2) in object code or executable form under the terms of 154 Sections 1 and 2 above provided that you also do one of the following: 155 156 a) Accompany it with the complete corresponding machine-readable 157 source code, which must be distributed under the terms of Sections 158 1 and 2 above on a medium customarily used for software interchange; or, 159 160 b) Accompany it with a written offer, valid for at least three 161 years, to give any third party, for a charge no more than your 162 cost of physically performing source distribution, a complete 163 machine-readable copy of the corresponding source code, to be 164 distributed under the terms of Sections 1 and 2 above on a medium 165 customarily used for software interchange; or, 166 167 c) Accompany it with the information you received as to the offer 168 to distribute corresponding source code. (This alternative is 169 allowed only for noncommercial distribution and only if you 170 received the program in object code or executable form with such 171 an offer, in accord with Subsection b above.) 172 173 The source code for a work means the preferred form of the work for 174 making modifications to it. For an executable work, complete source 175 code means all the source code for all modules it contains, plus any 176 associated interface definition files, plus the scripts used to 177 control compilation and installation of the executable. However, as a 178 special exception, the source code distributed need not include 179 anything that is normally distributed (in either source or binary 180 form) with the major components (compiler, kernel, and so on) of the 181 operating system on which the executable runs, unless that component 182 itself accompanies the executable. 183 184 If distribution of executable or object code is made by offering 185 access to copy from a designated place, then offering equivalent 186 access to copy the source code from the same place counts as 187 distribution of the source code, even though third parties are not 188 compelled to copy the source along with the object code. 189 190 4. You may not copy, modify, sublicense, or distribute the Program 191 except as expressly provided under this License. Any attempt 192 otherwise to copy, modify, sublicense or distribute the Program is 193 void, and will automatically terminate your rights under this License. 194 However, parties who have received copies, or rights, from you under 195 this License will not have their licenses terminated so long as such 196 parties remain in full compliance. 197 198 5. You are not required to accept this License, since you have not 199 signed it. However, nothing else grants you permission to modify or 200 distribute the Program or its derivative works. These actions are 201 prohibited by law if you do not accept this License. Therefore, by 202 modifying or distributing the Program (or any work based on the 203 Program), you indicate your acceptance of this License to do so, and 204 all its terms and conditions for copying, distributing or modifying 205 the Program or works based on it. 206 207 6. Each time you redistribute the Program (or any work based on the 208 Program), the recipient automatically receives a license from the 209 original licensor to copy, distribute or modify the Program subject to 210 these terms and conditions. You may not impose any further 211 restrictions on the recipients' exercise of the rights granted herein. 212 You are not responsible for enforcing compliance by third parties to 213 this License. 214 215 7. If, as a consequence of a court judgment or allegation of patent 216 infringement or for any other reason (not limited to patent issues), 217 conditions are imposed on you (whether by court order, agreement or 218 otherwise) that contradict the conditions of this License, they do not 219 excuse you from the conditions of this License. If you cannot 220 distribute so as to satisfy simultaneously your obligations under this 221 License and any other pertinent obligations, then as a consequence you 222 may not distribute the Program at all. For example, if a patent 223 license would not permit royalty-free redistribution of the Program by 224 all those who receive copies directly or indirectly through you, then 225 the only way you could satisfy both it and this License would be to 226 refrain entirely from distribution of the Program. 227 228 If any portion of this section is held invalid or unenforceable under 229 any particular circumstance, the balance of the section is intended to 230 apply and the section as a whole is intended to apply in other 231 circumstances. 232 233 It is not the purpose of this section to induce you to infringe any 234 patents or other property right claims or to contest validity of any 235 such claims; this section has the sole purpose of protecting the 236 integrity of the free software distribution system, which is 237 implemented by public license practices. Many people have made 238 generous contributions to the wide range of software distributed 239 through that system in reliance on consistent application of that 240 system; it is up to the author/donor to decide if he or she is willing 241 to distribute software through any other system and a licensee cannot 242 impose that choice. 243 244 This section is intended to make thoroughly clear what is believed to 245 be a consequence of the rest of this License. 246 247 8. If the distribution and/or use of the Program is restricted in 248 certain countries either by patents or by copyrighted interfaces, the 249 original copyright holder who places the Program under this License 250 may add an explicit geographical distribution limitation excluding 251 those countries, so that distribution is permitted only in or among 252 countries not thus excluded. In such case, this License incorporates 253 the limitation as if written in the body of this License. 254 255 9. The Free Software Foundation may publish revised and/or new versions 256 of the General Public License from time to time. Such new versions will 257 be similar in spirit to the present version, but may differ in detail to 258 address new problems or concerns. 259 260 Each version is given a distinguishing version number. If the Program 261 specifies a version number of this License which applies to it and "any 262 later version", you have the option of following the terms and conditions 263 either of that version or of any later version published by the Free 264 Software Foundation. If the Program does not specify a version number of 265 this License, you may choose any version ever published by the Free Software 266 Foundation. 267 268 10. If you wish to incorporate parts of the Program into other free 269 programs whose distribution conditions are different, write to the author 270 to ask for permission. For software which is copyrighted by the Free 271 Software Foundation, write to the Free Software Foundation; we sometimes 272 make exceptions for this. Our decision will be guided by the two goals 273 of preserving the free status of all derivatives of our free software and 274 of promoting the sharing and reuse of software generally. 275 276 NO WARRANTY 277 278 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY 279 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN 280 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES 281 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED 282 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF 283 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS 284 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE 285 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, 286 REPAIR OR CORRECTION. 287 288 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 289 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR 290 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, 291 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING 292 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED 293 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY 294 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER 295 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE 296 POSSIBILITY OF SUCH DAMAGES. 297 298 END OF TERMS AND CONDITIONS 299 300 How to Apply These Terms to Your New Programs 301 302 If you develop a new program, and you want it to be of the greatest 303 possible use to the public, the best way to achieve this is to make it 304 free software which everyone can redistribute and change under these terms. 305 306 To do so, attach the following notices to the program. It is safest 307 to attach them to the start of each source file to most effectively 308 convey the exclusion of warranty; and each file should have at least 309 the "copyright" line and a pointer to where the full notice is found. 310 311 <one line to give the program's name and a brief idea of what it does.> 312 Copyright (C) <year> <name of author> 313 314 This program is free software; you can redistribute it and/or modify 315 it under the terms of the GNU General Public License as published by 316 the Free Software Foundation; either version 2 of the License, or 317 (at your option) any later version. 318 319 This program is distributed in the hope that it will be useful, 320 but WITHOUT ANY WARRANTY; without even the implied warranty of 321 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the 322 GNU General Public License for more details. 323 324 You should have received a copy of the GNU General Public License 325 along with this program; if not, write to the Free Software 326 Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA. 327 328 329 Also add information on how to contact you by electronic and paper mail. 330 331 If the program is interactive, make it output a short notice like this 332 when it starts in an interactive mode: 333 334 Gnomovision version 69, Copyright (C) year name of author 335 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. 336 This is free software, and you are welcome to redistribute it 337 under certain conditions; type `show c' for details. 338 339 The hypothetical commands `show w' and `show c' should show the appropriate 340 parts of the General Public License. Of course, the commands you use may 341 be called something other than `show w' and `show c'; they could even be 342 mouse-clicks or menu items--whatever suits your program. 343 344 You should also get your employer (if you work as a programmer) or your 345 school, if any, to sign a "copyright disclaimer" for the program, if 346 necessary. Here is a sample; alter the names: 347 348 Yoyodyne, Inc., hereby disclaims all copyright interest in the program 349 `Gnomovision' (which makes passes at compilers) written by James Hacker. 350 351 <signature of Ty Coon>, 1 April 1989 352 Ty Coon, President of Vice 353 354 This General Public License does not permit incorporating your program into 355 proprietary programs. If your program is a subroutine library, you may 356 consider it more useful to permit linking proprietary applications with the 357 library. If this is what you want to do, use the GNU Library General 358 Public License instead of this License. 359 360 ****************************************************************************** 361 362 GNU LESSER GENERAL PUBLIC LICENSE 363 364 Version 2.1, February 1999 365 366 Copyright (C) 1991, 1999 Free Software Foundation, Inc. 367 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA 368 Everyone is permitted to copy and distribute verbatim copies 369 of this license document, but changing it is not allowed. 370 371 [This is the first released version of the Lesser GPL. It also counts 372 as the successor of the GNU Library Public License, version 2, hence 373 the version number 2.1.] 374 375 Preamble 376 377 The licenses for most software are designed to take away your freedom to 378 share and change it. By contrast, the GNU General Public Licenses are 379 intended to guarantee your freedom to share and change free software--to 380 make sure the software is free for all its users. 381 382 This license, the Lesser General Public License, applies to some specially 383 designated software packages--typically libraries--of the Free Software 384 Foundation and other authors who decide to use it. You can use it too, but 385 we suggest you first think carefully about whether this license or the 386 ordinary General Public License is the better strategy to use in any 387 particular case, based on the explanations below. 388 389 When we speak of free software, we are referring to freedom of use, not 390 price. Our General Public Licenses are designed to make sure that you 391 have the freedom to distribute copies of free software (and charge for 392 this service if you wish); that you receive source code or can get it 393 if you want it; that you can change the software and use pieces of it 394 in new free programs; and that you are informed that you can do these 395 things. 396 397 To protect your rights, we need to make restrictions that forbid 398 distributors to deny you these rights or to ask you to surrender these 399 rights. These restrictions translate to certain responsibilities for 400 you if you distribute copies of the library or if you modify it. 401 402 For example, if you distribute copies of the library, whether gratis or 403 for a fee, you must give the recipients all the rights that we gave you. 404 You must make sure that they, too, receive or can get the source code. 405 If you link other code with the library, you must provide complete object 406 files to the recipients, so that they can relink them with the library 407 after making changes to the library and recompiling it. And you must show 408 them these terms so they know their rights. 409 410 We protect your rights with a two-step method: (1) we copyright the 411 library, and (2) we offer you this license, which gives you legal 412 permission to copy, distribute and/or modify the library. 413 414 To protect each distributor, we want to make it very clear that there is 415 no warranty for the free library. Also, if the library is modified by 416 someone else and passed on, the recipients should know that what they 417 have is not the original version, so that the original author's reputation 418 will not be affected by problems that might be introduced by others. 419 420 Finally, software patents pose a constant threat to the existence of any 421 free program. We wish to make sure that a company cannot effectively 422 restrict the users of a free program by obtaining a restrictive license 423 from a patent holder. Therefore, we insist that any patent license 424 obtained for a version of the library must be consistent with the full 425 freedom of use specified in this license. 426 427 Most GNU software, including some libraries, is covered by the ordinary 428 GNU General Public License. This license, the GNU Lesser General Public 429 License, applies to certain designated libraries, and is quite different 430 from the ordinary General Public License. We use this license for certain 431 libraries in order to permit linking those libraries into non-free programs. 432 433 When a program is linked with a library, whether statically or using a 434 shared library, the combination of the two is legally speaking a combined 435 work, a derivative of the original library. The ordinary General Public 436 License therefore permits such linking only if the entire combination fits 437 its criteria of freedom. The Lesser General Public License permits more lax 438 criteria for linking other code with the library. 439 440 We call this license the "Lesser" General Public License because it does 441 Less to protect the user's freedom than the ordinary General Public License. 442 It also provides other free software developers Less of an advantage over 443 competing non-free programs. These disadvantages are the reason we use the 444 ordinary General Public License for many libraries. However, the Lesser 445 license provides advantages in certain special circumstances. 446 447 For example, on rare occasions, there may be a special need to encourage 448 the widest possible use of a certain library, so that it becomes a de-facto 449 standard. To achieve this, non-free programs must be allowed to use the 450 library. A more frequent case is that a free library does the same job as 451 widely used non-free libraries. In this case, there is little to gain by 452 limiting the free library to free software only, so we use the Lesser 453 General Public License. 454 455 In other cases, permission to use a particular library in non-free programs 456 enables a greater number of people to use a large body of free software. 457 For example, permission to use the GNU C Library in non-free programs 458 enables many more people to use the whole GNU operating system, as well 459 as its variant, the GNU/Linux operating system. 460 461 Although the Lesser General Public License is Less protective of the users' 462 freedom, it does ensure that the user of a program that is linked with the 463 Library has the freedom and the wherewithal to run that program using a 464 modified version of the Library. 465 466 The precise terms and conditions for copying, distribution and modification 467 follow. Pay close attention to the difference between a "work based on the 468 library" and a "work that uses the library". The former contains code derived 469 from the library, whereas the latter must be combined with the library in 470 order to run. 471 472 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 473 474 0. This License Agreement applies to any software library or other program 475 which contains a notice placed by the copyright holder or other authorized 476 party saying it may be distributed under the terms of this Lesser General 477 Public License (also called "this License"). Each licensee is addressed as 478 "you". 479 480 A "library" means a collection of software functions and/or data prepared 481 so as to be conveniently linked with application programs (which use some 482 of those functions and data) to form executables. 483 484 The "Library", below, refers to any such software library or work which 485 has been distributed under these terms. A "work based on the Library" 486 means either the Library or any derivative work under copyright law: 487 that is to say, a work containing the Library or a portion of it, either 488 verbatim or with modifications and/or translated straightforwardly into 489 another language. (Hereinafter, translation is included without limitation 490 in the term "modification".) 491 492 "Source code" for a work means the preferred form of the work for making 493 modifications to it. For a library, complete source code means all the 494 source code for all modules it contains, plus any associated interface 495 definition files, plus the scripts used to control compilation and 496 installation of the library. 497 498 Activities other than copying, distribution and modification are not covered 499 by this License; they are outside its scope. The act of running a program 500 using the Library is not restricted, and output from such a program is 501 covered only if its contents constitute a work based on the Library 502 (independent of the use of the Library in a tool for writing it). Whether 503 that is true depends on what the Library does and what the program that 504 uses the Library does. 505 506 1. You may copy and distribute verbatim copies of the Library's complete 507 source code as you receive it, in any medium, provided that you conspicuously 508 and appropriately publish on each copy an appropriate copyright notice and 509 disclaimer of warranty; keep intact all the notices that refer to this 510 License and to the absence of any warranty; and distribute a copy of this 511 License along with the Library. 512 513 You may charge a fee for the physical act of transferring a copy, and 514 you may at your option offer warranty protection in exchange for a fee. 515 516 2. You may modify your copy or copies of the Library or any portion of it, 517 thus forming a work based on the Library, and copy and distribute such 518 modifications or work under the terms of Section 1 above, provided that 519 you also meet all of these conditions: 520 521 a) The modified work must itself be a software library. 522 b) You must cause the files modified to carry prominent notices stating 523 that you changed the files and the date of any change. 524 c) You must cause the whole of the work to be licensed at no charge 525 to all third parties under the terms of this License. 526 d) If a facility in the modified Library refers to a function or a 527 table of data to be supplied by an application program that uses the 528 facility, other than as an argument passed when the facility is invoked, 529 then you must make a good faith effort to ensure that, in the event an 530 application does not supply such function or table, the facility still 531 operates, and performs whatever part of its purpose remains meaningful. 532 533 (For example, a function in a library to compute square roots has a 534 purpose that is entirely well-defined independent of the application. 535 Therefore, Subsection 2d requires that any application-supplied function 536 or table used by this function must be optional: if the application does 537 not supply it, the square root function must still compute square roots.) 538 539 These requirements apply to the modified work as a whole. If identifiable 540 sections of that work are not derived from the Library, and can be reasonably 541 considered independent and separate works in themselves, then this License, 542 and its terms, do not apply to those sections when you distribute them as 543 separate works. But when you distribute the same sections as part of a whole 544 which is a work based on the Library, the distribution of the whole must be 545 on the terms of this License, whose permissions for other licensees extend 546 to the entire whole, and thus to each and every part regardless of who wrote 547 it. 548 549 Thus, it is not the intent of this section to claim rights or contest your 550 rights to work written entirely by you; rather, the intent is to exercise 551 the right to control the distribution of derivative or collective works 552 based on the Library. 553 554 In addition, mere aggregation of another work not based on the Library with 555 the Library (or with a work based on the Library) on a volume of a storage 556 or distribution medium does not bring the other work under the scope of 557 this License. 558 559 3. You may opt to apply the terms of the ordinary GNU General Public License 560 instead of this License to a given copy of the Library. To do this, you must 561 alter all the notices that refer to this License, so that they refer to the 562 ordinary GNU General Public License, version 2, instead of to this License. 563 (If a newer version than version 2 of the ordinary GNU General Public License 564 has appeared, then you can specify that version instead if you wish.) Do not 565 make any other change in these notices. 566 567 Once this change is made in a given copy, it is irreversible for that copy, 568 so the ordinary GNU General Public License applies to all subsequent copies 569 and derivative works made from that copy. 570 571 This option is useful when you wish to copy part of the code of the Library 572 into a program that is not a library. 573 574 4. You may copy and distribute the Library (or a portion or derivative of 575 it, under Section 2) in object code or executable form under the terms of 576 Sections 1 and 2 above provided that you accompany it with the complete 577 corresponding machine-readable source code, which must be distributed under 578 the terms of Sections 1 and 2 above on a medium customarily used for software 579 interchange. 580 581 If distribution of object code is made by offering access to copy from a 582 designated place, then offering equivalent access to copy the source code 583 from the same place satisfies the requirement to distribute the source 584 code, even though third parties are not compelled to copy the source 585 along with the object code. 586 587 5. A program that contains no derivative of any portion of the Library, 588 but is designed to work with the Library by being compiled or linked with 589 it, is called a "work that uses the Library". Such a work, in isolation, 590 is not a derivative work of the Library, and therefore falls outside the 591 scope of this License. 592 593 However, linking a "work that uses the Library" with the Library creates 594 an executable that is a derivative of the Library (because it contains 595 portions of the Library), rather than a "work that uses the library". 596 The executable is therefore covered by this License. Section 6 states 597 terms for distribution of such executables. 598 599 When a "work that uses the Library" uses material from a header file 600 that is part of the Library, the object code for the work may be a 601 derivative work of the Library even though the source code is not. 602 Whether this is true is especially significant if the work can be 603 linked without the Library, or if the work is itself a library. 604 The threshold for this to be true is not precisely defined by law. 605 606 If such an object file uses only numerical parameters, data structure 607 layouts and accessors, and small macros and small inline functions 608 (ten lines or less in length), then the use of the object file is 609 unrestricted, regardless of whether it is legally a derivative work. 610 (Executables containing this object code plus portions of the Library 611 will still fall under Section 6.) 612 613 Otherwise, if the work is a derivative of the Library, you may 614 distribute the object code for the work under the terms of Section 6. 615 Any executables containing that work also fall under Section 6, whether 616 or not they are linked directly with the Library itself. 617 618 6. As an exception to the Sections above, you may also combine or link 619 a "work that uses the Library" with the Library to produce a work 620 containing portions of the Library, and distribute that work under 621 terms of your choice, provided that the terms permit modification of 622 the work for the customer's own use and reverse engineering for 623 debugging such modifications. 624 625 You must give prominent notice with each copy of the work that the 626 Library is used in it and that the Library and its use are covered 627 by this License. You must supply a copy of this License. If the work 628 during execution displays copyright notices, you must include the 629 copyright notice for the Library among them, as well as a reference 630 directing the user to the copy of this License. Also, you must do 631 one of these things: 632 633 a) Accompany the work with the complete corresponding machine-readable 634 source code for the Library including whatever changes were used in the 635 work (which must be distributed under Sections 1 and 2 above); and, if 636 the work is an executable linked with the Library, with the complete 637 machine-readable "work that uses the Library", as object code and/or 638 source code, so that the user can modify the Library and then relink 639 to produce a modified executable containing the modified Library. (It 640 is understood that the user who changes the contents of definitions 641 files in the Library will not necessarily be able to recompile the 642 application to use the modified definitions.) 643 b) Use a suitable shared library mechanism for linking with the Library. 644 A suitable mechanism is one that (1) uses at run time a copy of the 645 library already present on the user's computer system, rather than 646 copying library functions into the executable, and (2) will operate 647 properly with a modified version of the library, if the user installs 648 one, as long as the modified version is interface-compatible with the 649 version that the work was made with. 650 c) Accompany the work with a written offer, valid for at least three 651 years, to give the same user the materials specified in Subsection 6a, 652 above, for a charge no more than the cost of performing this distribution. 653 d) If distribution of the work is made by offering access to copy from a 654 designated place, offer equivalent access to copy the above specified 655 materials from the same place. 656 e) Verify that the user has already received a copy of these materials or 657 that you have already sent this user a copy. 658 659 For an executable, the required form of the "work that uses the Library" 660 must include any data and utility programs needed for reproducing the 661 executable from it. However, as a special exception, the materials to be 662 distributed need not include anything that is normally distributed (in 663 either source or binary form) with the major components (compiler, kernel, 664 and so on) of the operating system on which the executable runs, unless 665 that component itself accompanies the executable. 666 667 It may happen that this requirement contradicts the license restrictions of 668 other proprietary libraries that do not normally accompany the operating 669 system. Such a contradiction means you cannot use both them and the Library 670 together in an executable that you distribute. 671 672 7. You may place library facilities that are a work based on the Library 673 side-by-side in a single library together with other library facilities 674 not covered by this License, and distribute such a combined library, provided 675 that the separate distribution of the work based on the Library and of the 676 other library facilities is otherwise permitted, and provided that you do 677 these two things: 678 679 a) Accompany the combined library with a copy of the same work based on the 680 Library, uncombined with any other library facilities. This must be 681 distributed under the terms of the Sections above. 682 b) Give prominent notice with the combined library of the fact that part 683 of it is a work based on the Library, and explaining where to find the 684 accompanying uncombined form of the same work. 685 686 8. You may not copy, modify, sublicense, link with, or distribute the Library 687 except as expressly provided under this License. Any attempt otherwise to 688 copy, modify, sublicense, link with, or distribute the Library is void, and 689 will automatically terminate your rights under this License. However, parties 690 who have received copies, or rights, from you under this License will not have 691 their licenses terminated so long as such parties remain in full compliance. 692 693 9. You are not required to accept this License, since you have not signed 694 it. However, nothing else grants you permission to modify or distribute 695 the Library or its derivative works. These actions are prohibited by law 696 if you do not accept this License. Therefore, by modifying or distributing 697 the Library (or any work based on the Library), you indicate your acceptance 698 of this License to do so, and all its terms and conditions for copying, 699 distributing or modifying the Library or works based on it. 700 701 10. Each time you redistribute the Library (or any work based on the Library), 702 the recipient automatically receives a license from the original licensor to 703 copy, distribute, link with or modify the Library subject to these terms and 704 conditions. You may not impose any further restrictions on the recipients' 705 exercise of the rights granted herein. You are not responsible for enforcing 706 compliance by third parties with this License. 707 708 11. If, as a consequence of a court judgment or allegation of patent 709 infringement or for any other reason (not limited to patent issues), 710 conditions are imposed on you (whether by court order, agreement or 711 otherwise) that contradict the conditions of this License, they do not 712 excuse you from the conditions of this License. If you cannot distribute 713 so as to satisfy simultaneously your obligations under this License and 714 any other pertinent obligations, then as a consequence you may not distribute 715 the Library at all. For example, if a patent license would not permit 716 royalty-free redistribution of the Library by all those who receive 717 copies directly or indirectly through you, then the only way you could 718 satisfy both it and this License would be to refrain entirely from 719 distribution of the Library. 720 721 If any portion of this section is held invalid or unenforceable under 722 any particular circumstance, the balance of the section is intended to 723 apply, and the section as a whole is intended to apply in other 724 circumstances. 725 726 It is not the purpose of this section to induce you to infringe any 727 patents or other property right claims or to contest validity of any 728 such claims; this section has the sole purpose of protecting the 729 integrity of the free software distribution system which is implemented 730 by public license practices. Many people have made generous contributions 731 to the wide range of software distributed through that system in reliance 732 on consistent application of that system; it is up to the author/donor 733 to decide if he or she is willing to distribute software through any 734 other system and a licensee cannot impose that choice. 735 736 This section is intended to make thoroughly clear what is believed to 737 be a consequence of the rest of this License. 738 739 12. If the distribution and/or use of the Library is restricted in certain 740 countries either by patents or by copyrighted interfaces, the original 741 copyright holder who places the Library under this License may add an 742 explicit geographical distribution limitation excluding those countries, 743 so that distribution is permitted only in or among countries not thus 744 excluded. In such case, this License incorporates the limitation as if 745 written in the body of this License. 746 747 13. The Free Software Foundation may publish revised and/or new versions 748 of the Lesser General Public License from time to time. Such new versions 749 will be similar in spirit to the present version, but may differ in detail 750 to address new problems or concerns. 751 752 Each version is given a distinguishing version number. If the Library 753 specifies a version number of this License which applies to it and "any 754 later version", you have the option of following the terms and conditions 755 either of that version or of any later version published by the Free 756 Software Foundation. If the Library does not specify a license version 757 number, you may choose any version ever published by the Free Software 758 Foundation. 759 760 14. If you wish to incorporate parts of the Library into other free programs 761 whose distribution conditions are incompatible with these, write to the author 762 to ask for permission. For software which is copyrighted by the Free Software 763 Foundation, write to the Free Software Foundation; we sometimes make exceptions 764 for this. Our decision will be guided by the two goals of preserving the free 765 status of all derivatives of our free software and of promoting the sharing 766 and reuse of software generally. 767 768 NO WARRANTY 769 770 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR 771 THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE 772 STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE 773 LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, 774 INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND 775 FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND 776 PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, 777 YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 778 779 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL 780 ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE 781 THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY 782 GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE 783 OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA 784 OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES 785 OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF 786 SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. 787 788 END OF TERMS AND CONDITIONS 789 790
