It also counts 104 as the successor of the GNU Library Public License, version 2, hence 105 the version number 2.1.] 106 107 Preamble 108 109 The licenses for most software are designed to take away your 110 freedom to share and change it. By contrast, the GNU General Public 111 Licenses are intended to guarantee your freedom to share and change 112 free software--to make sure the software is free for all its users. 113 114 This license, the Lesser General Public License, applies to some 115 specially designated software packages--typically libraries--of the 116 Free Software Foundation and other authors who decide to use it. You 117 can use it too, but we suggest you first think carefully about whether 118 this license or the ordinary General Public License is the better 119 strategy to use in any particular case, based on the explanations below. 120 121 When we speak of free software, we are referring to freedom of use, 122 not price. Our General Public Licenses are designed to make sure that 123 you have the freedom to distribute copies of free software (and charge 124 for this service if you wish); that you receive source code or can get 125 it if you want it; that you can change the software and use pieces of 126 it in new free programs; and that you are informed that you can do 127 these things. 128 129 To protect your rights, we need to make restrictions that forbid 130 distributors to deny you these rights or to ask you to surrender these 131 rights. These restrictions translate to certain responsibilities for 132 you if you distribute copies of the library or if you modify it. 133 134 For example, if you distribute copies of the library, whether gratis 135 or for a fee, you must give the recipients all the rights that we gave 136 you. You must make sure that they, too, receive or can get the source 137 code. If you link other code with the library, you must provide 138 complete object files to the recipients, so that they can relink them 139 with the library after making changes to the library and recompiling 140 it. And you must show them these terms so they know their rights. 141 142 We protect your rights with a two-step method: (1) we copyright the 143 library, and (2) we offer you this license, which gives you legal 144 permission to copy, distribute and/or modify the library. 145 146 To protect each distributor, we want to make it very clear that 147 there is no warranty for the free library. Also, if the library is 148 modified by someone else and passed on, the recipients should know 149 that what they have is not the original version, so that the original 150 author's reputation will not be affected by problems that might be 151 introduced by others. 152 153 Finally, software patents pose a constant threat to the existence of 154 any free program. We wish to make sure that a company cannot 155 effectively restrict the users of a free program by obtaining a 156 restrictive license from a patent holder. Therefore, we insist that 157 any patent license obtained for a version of the library must be 158 consistent with the full freedom of use specified in this license. 159 160 Most GNU software, including some libraries, is covered by the 161 ordinary GNU General Public License. This license, the GNU Lesser 162 General Public License, applies to certain designated libraries, and 163 is quite different from the ordinary General Public License. We use 164 this license for certain libraries in order to permit linking those 165 libraries into non-free programs. 166 167 When a program is linked with a library, whether statically or using 168 a shared library, the combination of the two is legally speaking a 169 combined work, a derivative of the original library. The ordinary 170 General Public License therefore permits such linking only if the 171 entire combination fits its criteria of freedom. The Lesser General 172 Public License permits more lax criteria for linking other code with 173 the library. 174 175 We call this license the "Lesser" General Public License because it 176 does Less to protect the user's freedom than the ordinary General 177 Public License. It also provides other free software developers Less 178 of an advantage over competing non-free programs. These disadvantages 179 are the reason we use the ordinary General Public License for many 180 libraries. However, the Lesser license provides advantages in certain 181 special circumstances. 182 183 For example, on rare occasions, there may be a special need to 184 encourage the widest possible use of a certain library, so that it becomes 185 a de-facto standard. To achieve this, non-free programs must be 186 allowed to use the library. A more frequent case is that a free 187 library does the same job as widely used non-free libraries. In this 188 case, there is little to gain by limiting the free library to free 189 software only, so we use the Lesser General Public License. 190 191 In other cases, permission to use a particular library in non-free 192 programs enables a greater number of people to use a large body of 193 free software. For example, permission to use the GNU C Library in 194 non-free programs enables many more people to use the whole GNU 195 operating system, as well as its variant, the GNU/Linux operating 196 system. 197 198 Although the Lesser General Public License is Less protective of the 199 users' freedom, it does ensure that the user of a program that is 200 linked with the Library has the freedom and the wherewithal to run 201 that program using a modified version of the Library. 202 203 The precise terms and conditions for copying, distribution and 204 modification follow. Pay close attention to the difference between a 205 "work based on the library" and a "work that uses the library". The 206 former contains code derived from the library, whereas the latter must 207 be combined with the library in order to run. 208 209 GNU LESSER GENERAL PUBLIC LICENSE 210 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 211 212 0. This License Agreement applies to any software library or other 213 program which contains a notice placed by the copyright holder or 214 other authorized party saying it may be distributed under the terms of 215 this Lesser General Public License (also called "this License"). 216 Each licensee is addressed as "you". 217 218 A "library" means a collection of software functions and/or data 219 prepared so as to be conveniently linked with application programs 220 (which use some of those functions and data) to form executables. 221 222 The "Library", below, refers to any such software library or work 223 which has been distributed under these terms. A "work based on the 224 Library" means either the Library or any derivative work under 225 copyright law: that is to say, a work containing the Library or a 226 portion of it, either verbatim or with modifications and/or translated 227 straightforwardly into another language. (Hereinafter, translation is 228 included without limitation in the term "modification".) 229 230 "Source code" for a work means the preferred form of the work for 231 making modifications to it. For a library, complete source code means 232 all the source code for all modules it contains, plus any associated 233 interface definition files, plus the scripts used to control compilation 234 and installation of the library. 235 236 Activities other than copying, distribution and modification are not 237 covered by this License; they are outside its scope. The act of 238 running a program using the Library is not restricted, and output from 239 such a program is covered only if its contents constitute a work based 240 on the Library (independent of the use of the Library in a tool for 241 writing it). Whether that is true depends on what the Library does 242 and what the program that uses the Library does. 243 244 1. You may copy and distribute verbatim copies of the Library's 245 complete source code as you receive it, in any medium, provided that 246 you conspicuously and appropriately publish on each copy an 247 appropriate copyright notice and disclaimer of warranty; keep intact 248 all the notices that refer to this License and to the absence of any 249 warranty; and distribute a copy of this License along with the 250 Library. 251 252 You may charge a fee for the physical act of transferring a copy, 253 and you may at your option offer warranty protection in exchange for a 254 fee. 255 256 2. You may modify your copy or copies of the Library or any portion 257 of it, thus forming a work based on the Library, and copy and 258 distribute such modifications or work under the terms of Section 1 259 above, provided that you also meet all of these conditions: 260 261 a) The modified work must itself be a software library. 262 263 b) You must cause the files modified to carry prominent notices 264 stating that you changed the files and the date of any change. 265 266 c) You must cause the whole of the work to be licensed at no 267 charge to all third parties under the terms of this License. 268 269 d) If a facility in the modified Library refers to a function or a 270 table of data to be supplied by an application program that uses 271 the facility, other than as an argument passed when the facility 272 is invoked, then you must make a good faith effort to ensure that, 273 in the event an application does not supply such function or 274 table, the facility still operates, and performs whatever part of 275 its purpose remains meaningful. 276 277 (For example, a function in a library to compute square roots has 278 a purpose that is entirely well-defined independent of the 279 application. Therefore, Subsection 2d requires that any 280 application-supplied function or table used by this function must 281 be optional: if the application does not supply it, the square 282 root function must still compute square roots.) 283 284 These requirements apply to the modified work as a whole. If 285 identifiable sections of that work are not derived from the Library, 286 and can be reasonably considered independent and separate works in 287 themselves, then this License, and its terms, do not apply to those 288 sections when you distribute them as separate works. But when you 289 distribute the same sections as part of a whole which is a work based 290 on the Library, the distribution of the whole must be on the terms of 291 this License, whose permissions for other licensees extend to the 292 entire whole, and thus to each and every part regardless of who wrote 293 it. 294 295 Thus, it is not the intent of this section to claim rights or contest 296 your rights to work written entirely by you; rather, the intent is to 297 exercise the right to control the distribution of derivative or 298 collective works based on the Library. 299 300 In addition, mere aggregation of another work not based on the Library 301 with the Library (or with a work based on the Library) on a volume of 302 a storage or distribution medium does not bring the other work under 303 the scope of this License. 304 305 3. You may opt to apply the terms of the ordinary GNU General Public 306 License instead of this License to a given copy of the Library. To do 307 this, you must alter all the notices that refer to this License, so 308 that they refer to the ordinary GNU General Public License, version 2, 309 instead of to this License. (If a newer version than version 2 of the 310 ordinary GNU General Public License has appeared, then you can specify 311 that version instead if you wish.) Do not make any other change in 312 these notices. 313 314 Once this change is made in a given copy, it is irreversible for 315 that copy, so the ordinary GNU General Public License applies to all 316 subsequent copies and derivative works made from that copy. 317 318 This option is useful when you wish to copy part of the code of 319 the Library into a program that is not a library. 320 321 4. You may copy and distribute the Library (or a portion or 322 derivative of it, under Section 2) in object code or executable form 323 under the terms of Sections 1 and 2 above provided that you accompany 324 it with the complete corresponding machine-readable source code, which 325 must be distributed under the terms of Sections 1 and 2 above on a 326 medium customarily used for software interchange. 327 328 If distribution of object code is made by offering access to copy 329 from a designated place, then offering equivalent access to copy the 330 source code from the same place satisfies the requirement to 331 distribute the source code, even though third parties are not 332 compelled to copy the source along with the object code. 333 334 5. A program that contains no derivative of any portion of the 335 Library, but is designed to work with the Library by being compiled or 336 linked with it, is called a "work that uses the Library". Such a 337 work, in isolation, is not a derivative work of the Library, and 338 therefore falls outside the scope of this License. 339 340 However, linking a "work that uses the Library" with the Library 341 creates an executable that is a derivative of the Library (because it 342 contains portions of the Library), rather than a "work that uses the 343 library". The executable is therefore covered by this License. 344 Section 6 states terms for distribution of such executables. 345 346 When a "work that uses the Library" uses material from a header file 347 that is part of the Library, the object code for the work may be a 348 derivative work of the Library even though the source code is not. 349 Whether this is true is especially significant if the work can be 350 linked without the Library, or if the work is itself a library. The 351 threshold for this to be true is not precisely defined by law. 352 353 If such an object file uses only numerical parameters, data 354 structure layouts and accessors, and small macros and small inline 355 functions (ten lines or less in length), then the use of the object 356 file is unrestricted, regardless of whether it is legally a derivative 357 work. (Executables containing this object code plus portions of the 358 Library will still fall under Section 6.) 359 360 Otherwise, if the work is a derivative of the Library, you may 361 distribute the object code for the work under the terms of Section 6. 362 Any executables containing that work also fall under Section 6, 363 whether or not they are linked directly with the Library itself. 364 365 6. As an exception to the Sections above, you may also combine or 366 link a "work that uses the Library" with the Library to produce a 367 work containing portions of the Library, and distribute that work 368 under terms of your choice, provided that the terms permit 369 modification of the work for the customer's own use and reverse 370 engineering for debugging such modifications. 371 372 You must give prominent notice with each copy of the work that the 373 Library is used in it and that the Library and its use are covered by 374 this License. You must supply a copy of this License. If the work 375 during execution displays copyright notices, you must include the 376 copyright notice for the Library among them, as well as a reference 377 directing the user to the copy of this License. Also, you must do one 378 of these things: 379 380 a) Accompany the work with the complete corresponding 381 machine-readable source code for the Library including whatever 382 changes were used in the work (which must be distributed under 383 Sections 1 and 2 above); and, if the work is an executable linked 384 with the Library, with the complete machine-readable "work that 385 uses the Library", as object code and/or source code, so that the 386 user can modify the Library and then relink to produce a modified 387 executable containing the modified Library. (It is understood 388 that the user who changes the contents of definitions files in the 389 Library will not necessarily be able to recompile the application 390 to use the modified definitions.) 391 392 b) Use a suitable shared library mechanism for linking with the 393 Library. A suitable mechanism is one that (1) uses at run time a 394 copy of the library already present on the user's computer system, 395 rather than copying library functions into the executable, and (2) 396 will operate properly with a modified version of the library, if 397 the user installs one, as long as the modified version is 398 interface-compatible with the version that the work was made with. 399 400 c) Accompany the work with a written offer, valid for at 401 least three years, to give the same user the materials 402 specified in Subsection 6a, above, for a charge no more 403 than the cost of performing this distribution. 404 405 d) If distribution of the work is made by offering access to copy 406 from a designated place, offer equivalent access to copy the above 407 specified materials from the same place. 408 409 e) Verify that the user has already received a copy of these 410 materials or that you have already sent this user a copy. 411 412 For an executable, the required form of the "work that uses the 413 Library" must include any data and utility programs needed for 414 reproducing the executable from it. However, as a special exception, 415 the materials to be distributed need not include anything that is 416 normally distributed (in either source or binary form) with the major 417 components (compiler, kernel, and so on) of the operating system on 418 which the executable runs, unless that component itself accompanies 419 the executable. 420 421 It may happen that this requirement contradicts the license 422 restrictions of other proprietary libraries that do not normally 423 accompany the operating system. Such a contradiction means you cannot 424 use both them and the Library together in an executable that you 425 distribute. 426 427 7. You may place library facilities that are a work based on the 428 Library side-by-side in a single library together with other library 429 facilities not covered by this License, and distribute such a combined 430 library, provided that the separate distribution of the work based on 431 the Library and of the other library facilities is otherwise 432 permitted, and provided that you do these two things: 433 434 a) Accompany the combined library with a copy of the same work 435 based on the Library, uncombined with any other library 436 facilities. This must be distributed under the terms of the 437 Sections above. 438 439 b) Give prominent notice with the combined library of the fact 440 that part of it is a work based on the Library, and explaining 441 where to find the accompanying uncombined form of the same work. 442 443 8. You may not copy, modify, sublicense, link with, or distribute 444 the Library except as expressly provided under this License. Any 445 attempt otherwise to copy, modify, sublicense, link with, or 446 distribute the Library is void, and will automatically terminate your 447 rights under this License. However, parties who have received copies, 448 or rights, from you under this License will not have their licenses 449 terminated so long as such parties remain in full compliance. 450 451 9. You are not required to accept this License, since you have not 452 signed it. However, nothing else grants you permission to modify or 453 distribute the Library or its derivative works. These actions are 454 prohibited by law if you do not accept this License. Therefore, by 455 modifying or distributing the Library (or any work based on the 456 Library), you indicate your acceptance of this License to do so, and 457 all its terms and conditions for copying, distributing or modifying 458 the Library or works based on it. 459 460 10. Each time you redistribute the Library (or any work based on the 461 Library), the recipient automatically receives a license from the 462 original licensor to copy, distribute, link with or modify the Library 463 subject to these terms and conditions. You may not impose any further 464 restrictions on the recipients' exercise of the rights granted herein. 465 You are not responsible for enforcing compliance by third parties with 466 this License. 467 468 11. If, as a consequence of a court judgment or allegation of patent 469 infringement or for any other reason (not limited to patent issues), 470 conditions are imposed on you (whether by court order, agreement or 471 otherwise) that contradict the conditions of this License, they do not 472 excuse you from the conditions of this License. If you cannot 473 distribute so as to satisfy simultaneously your obligations under this 474 License and any other pertinent obligations, then as a consequence you 475 may not distribute the Library at all. For example, if a patent 476 license would not permit royalty-free redistribution of the Library by 477 all those who receive copies directly or indirectly through you, then 478 the only way you could satisfy both it and this License would be to 479 refrain entirely from distribution of the Library. 480 481 If any portion of this section is held invalid or unenforceable under any 482 particular circumstance, the balance of the section is intended to apply, 483 and the section as a whole is intended to apply in other circumstances. 484 485 It is not the purpose of this section to induce you to infringe any 486 patents or other property right claims or to contest validity of any 487 such claims; this section has the sole purpose of protecting the 488 integrity of the free software distribution system which is 489 implemented by public license practices. Many people have made 490 generous contributions to the wide range of software distributed 491 through that system in reliance on consistent application of that 492 system; it is up to the author/donor to decide if he or she is willing 493 to distribute software through any other system and a licensee cannot 494 impose that choice. 495 496 This section is intended to make thoroughly clear what is believed to 497 be a consequence of the rest of this License. 498 499 12. If the distribution and/or use of the Library is restricted in 500 certain countries either by patents or by copyrighted interfaces, the 501 original copyright holder who places the Library under this License may add 502 an explicit geographical distribution limitation excluding those countries, 503 so that distribution is permitted only in or among countries not thus 504 excluded. In such case, this License incorporates the limitation as if 505 written in the body of this License. 506 507 13. The Free Software Foundation may publish revised and/or new 508 versions of the Lesser General Public License from time to time. 509 Such new versions will be similar in spirit to the present version, 510 but may differ in detail to address new problems or concerns. 511 512 Each version is given a distinguishing version number. If the Library 513 specifies a version number of this License which applies to it and 514 "any later version", you have the option of following the terms and 515 conditions either of that version or of any later version published by 516 the Free Software Foundation. If the Library does not specify a 517 license version number, you may choose any version ever published by 518 the Free Software Foundation. 519 520 14. If you wish to incorporate parts of the Library into other free 521 programs whose distribution conditions are incompatible with these, 522 write to the author to ask for permission. For software which is 523 copyrighted by the Free Software Foundation, write to the Free 524 Software Foundation; we sometimes make exceptions for this. Our 525 decision will be guided by the two goals of preserving the free status 526 of all derivatives of our free software and of promoting the sharing 527 and reuse of software generally. 528 529 NO WARRANTY 530 531 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO 532 WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. 533 EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR 534 OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY 535 KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE 536 IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR 537 PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE 538 LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME 539 THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 540 541 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN 542 WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY 543 AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU 544 FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR 545 CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE 546 LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING 547 RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A 548 FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF 549 SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH 550 DAMAGES. 551 552 END OF TERMS AND CONDITIONS 553 554 How to Apply These Terms to Your New Libraries 555 556 If you develop a new library, and you want it to be of the greatest 557 possible use to the public, we recommend making it free software that 558 everyone can redistribute and change. You can do so by permitting 559 redistribution under these terms (or, alternatively, under the terms of the 560 ordinary General Public License). 561 562 To apply these terms, attach the following notices to the library. It is 563 safest to attach them to the start of each source file to most effectively 564 convey the exclusion of warranty; and each file should have at least the 565 "copyright" line and a pointer to where the full notice is found. 566 567 <one line to give the library's name and a brief idea of what it does.> 568 Copyright (C) <year> <name of author> 569 570 This library is free software; you can redistribute it and/or 571 modify it under the terms of the GNU Lesser General Public 572 License as published by the Free Software Foundation; either 573 version 2.1 of the License, or (at your option) any later version. 574 575 This library is distributed in the hope that it will be useful, 576 but WITHOUT ANY WARRANTY; without even the implied warranty of 577 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
