0001 GNU LESSER GENERAL PUBLIC LICENSE 0002 0003 Version 2.1, February 1999 0004 0005 Copyright (C) 1991, 1999 Free Software Foundation, Inc. 0006 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA 0007 0008 Everyone is permitted to copy and distribute verbatim copies of this license 0009 document, but changing it is not allowed. 0010 0011 [This is the first released version of the Lesser GPL. It also counts as 0012 the successor of the GNU Library Public License, version 2, hence the version 0013 number 2.1.] 0014 0015 Preamble 0016 0017 The licenses for most software are designed to take away your freedom to share 0018 and change it. By contrast, the GNU General Public Licenses are intended to 0019 guarantee your freedom to share and change free software--to make sure the 0020 software is free for all its users. 0021 0022 This license, the Lesser General Public License, applies to some specially 0023 designated software packages--typically libraries--of the Free Software Foundation 0024 and other authors who decide to use it. You can use it too, but we suggest 0025 you first think carefully about whether this license or the ordinary General 0026 Public License is the better strategy to use in any particular case, based 0027 on the explanations below. 0028 0029 When we speak of free software, we are referring to freedom of use, not price. 0030 Our General Public Licenses are designed to make sure that you have the freedom 0031 to distribute copies of free software (and charge for this service if you 0032 wish); that you receive source code or can get it if you want it; that you 0033 can change the software and use pieces of it in new free programs; and that 0034 you are informed that you can do these things. 0035 0036 To protect your rights, we need to make restrictions that forbid distributors 0037 to deny you these rights or to ask you to surrender these rights. These restrictions 0038 translate to certain responsibilities for you if you distribute copies of 0039 the library or if you modify it. 0040 0041 For example, if you distribute copies of the library, whether gratis or for 0042 a fee, you must give the recipients all the rights that we gave you. You must 0043 make sure that they, too, receive or can get the source code. If you link 0044 other code with the library, you must provide complete object files to the 0045 recipients, so that they can relink them with the library after making changes 0046 to the library and recompiling it. And you must show them these terms so they 0047 know their rights. 0048 0049 We protect your rights with a two-step method: (1) we copyright the library, 0050 and (2) we offer you this license, which gives you legal permission to copy, 0051 distribute and/or modify the library. 0052 0053 To protect each distributor, we want to make it very clear that there is no 0054 warranty for the free library. Also, if the library is modified by someone 0055 else and passed on, the recipients should know that what they have is not 0056 the original version, so that the original author's reputation will not be 0057 affected by problems that might be introduced by others. 0058 0059 Finally, software patents pose a constant threat to the existence of any free 0060 program. We wish to make sure that a company cannot effectively restrict the 0061 users of a free program by obtaining a restrictive license from a patent holder. 0062 Therefore, we insist that any patent license obtained for a version of the 0063 library must be consistent with the full freedom of use specified in this 0064 license. 0065 0066 Most GNU software, including some libraries, is covered by the ordinary GNU 0067 General Public License. This license, the GNU Lesser General Public License, 0068 applies to certain designated libraries, and is quite different from the ordinary 0069 General Public License. We use this license for certain libraries in order 0070 to permit linking those libraries into non-free programs. 0071 0072 When a program is linked with a library, whether statically or using a shared 0073 library, the combination of the two is legally speaking a combined work, a 0074 derivative of the original library. The ordinary General Public License therefore 0075 permits such linking only if the entire combination fits its criteria of freedom. 0076 The Lesser General Public License permits more lax criteria for linking other 0077 code with the library. 0078 0079 We call this license the "Lesser" General Public License because it does Less 0080 to protect the user's freedom than the ordinary General Public License. It 0081 also provides other free software developers Less of an advantage over competing 0082 non-free programs. These disadvantages are the reason we use the ordinary 0083 General Public License for many libraries. However, the Lesser license provides 0084 advantages in certain special circumstances. 0085 0086 For example, on rare occasions, there may be a special need to encourage the 0087 widest possible use of a certain library, so that it becomes a de-facto standard. 0088 To achieve this, non-free programs must be allowed to use the library. A more 0089 frequent case is that a free library does the same job as widely used non-free 0090 libraries. In this case, there is little to gain by limiting the free library 0091 to free software only, so we use the Lesser General Public License. 0092 0093 In other cases, permission to use a particular library in non-free programs 0094 enables a greater number of people to use a large body of free software. For 0095 example, permission to use the GNU C Library in non-free programs enables 0096 many more people to use the whole GNU operating system, as well as its variant, 0097 the GNU/Linux operating system. 0098 0099 Although the Lesser General Public License is Less protective of the users' 0100 freedom, it does ensure that the user of a program that is linked with the 0101 Library has the freedom and the wherewithal to run that program using a modified 0102 version of the Library. 0103 0104 The precise terms and conditions for copying, distribution and modification 0105 follow. Pay close attention to the difference between a "work based on the 0106 library" and a "work that uses the library". The former contains code derived 0107 from the library, whereas the latter must be combined with the library in 0108 order to run. 0109 0110 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0111 0112 0. This License Agreement applies to any software library or other program 0113 which contains a notice placed by the copyright holder or other authorized 0114 party saying it may be distributed under the terms of this Lesser General 0115 Public License (also called "this License"). Each licensee is addressed as 0116 "you". 0117 0118 A "library" means a collection of software functions and/or data prepared 0119 so as to be conveniently linked with application programs (which use some 0120 of those functions and data) to form executables. 0121 0122 The "Library", below, refers to any such software library or work which has 0123 been distributed under these terms. A "work based on the Library" means either 0124 the Library or any derivative work under copyright law: that is to say, a 0125 work containing the Library or a portion of it, either verbatim or with modifications 0126 and/or translated straightforwardly into another language. (Hereinafter, translation 0127 is included without limitation in the term "modification".) 0128 0129 "Source code" for a work means the preferred form of the work for making modifications 0130 to it. For a library, complete source code means all the source code for all 0131 modules it contains, plus any associated interface definition files, plus 0132 the scripts used to control compilation and installation of the library. 0133 0134 Activities other than copying, distribution and modification are not covered 0135 by this License; they are outside its scope. The act of running a program 0136 using the Library is not restricted, and output from such a program is covered 0137 only if its contents constitute a work based on the Library (independent of 0138 the use of the Library in a tool for writing it). Whether that is true depends 0139 on what the Library does and what the program that uses the Library does. 0140 0141 1. You may copy and distribute verbatim copies of the Library's complete source 0142 code as you receive it, in any medium, provided that you conspicuously and 0143 appropriately publish on each copy an appropriate copyright notice and disclaimer 0144 of warranty; keep intact all the notices that refer to this License and to 0145 the absence of any warranty; and distribute a copy of this License along with 0146 the Library. 0147 0148 You may charge a fee for the physical act of transferring a copy, and you 0149 may at your option offer warranty protection in exchange for a fee. 0150 0151 2. You may modify your copy or copies of the Library or any portion of it, 0152 thus forming a work based on the Library, and copy and distribute such modifications 0153 or work under the terms of Section 1 above, provided that you also meet all 0154 of these conditions: 0155 0156 a) The modified work must itself be a software library. 0157 0158 b) You must cause the files modified to carry prominent notices stating that 0159 you changed the files and the date of any change. 0160 0161 c) You must cause the whole of the work to be licensed at no charge to all 0162 third parties under the terms of this License. 0163 0164 d) If a facility in the modified Library refers to a function or a table of 0165 data to be supplied by an application program that uses the facility, other 0166 than as an argument passed when the facility is invoked, then you must make 0167 a good faith effort to ensure that, in the event an application does not supply 0168 such function or table, the facility still operates, and performs whatever 0169 part of its purpose remains meaningful. 0170 0171 (For example, a function in a library to compute square roots has a purpose 0172 that is entirely well-defined independent of the application. Therefore, Subsection 0173 2d requires that any application-supplied function or table used by this function 0174 must be optional: if the application does not supply it, the square root function 0175 must still compute square roots.) 0176 0177 These requirements apply to the modified work as a whole. If identifiable 0178 sections of that work are not derived from the Library, and can be reasonably 0179 considered independent and separate works in themselves, then this License, 0180 and its terms, do not apply to those sections when you distribute them as 0181 separate works. But when you distribute the same sections as part of a whole 0182 which is a work based on the Library, the distribution of the whole must be 0183 on the terms of this License, whose permissions for other licensees extend 0184 to the entire whole, and thus to each and every part regardless of who wrote 0185 it. 0186 0187 Thus, it is not the intent of this section to claim rights or contest your 0188 rights to work written entirely by you; rather, the intent is to exercise 0189 the right to control the distribution of derivative or collective works based 0190 on the Library. 0191 0192 In addition, mere aggregation of another work not based on the Library with 0193 the Library (or with a work based on the Library) on a volume of a storage 0194 or distribution medium does not bring the other work under the scope of this 0195 License. 0196 0197 3. You may opt to apply the terms of the ordinary GNU General Public License 0198 instead of this License to a given copy of the Library. To do this, you must 0199 alter all the notices that refer to this License, so that they refer to the 0200 ordinary GNU General Public License, version 2, instead of to this License. 0201 (If a newer version than version 2 of the ordinary GNU General Public License 0202 has appeared, then you can specify that version instead if you wish.) Do not 0203 make any other change in these notices. 0204 0205 Once this change is made in a given copy, it is irreversible for that copy, 0206 so the ordinary GNU General Public License applies to all subsequent copies 0207 and derivative works made from that copy. 0208 0209 This option is useful when you wish to copy part of the code of the Library 0210 into a program that is not a library. 0211 0212 4. You may copy and distribute the Library (or a portion or derivative of 0213 it, under Section 2) in object code or executable form under the terms of 0214 Sections 1 and 2 above provided that you accompany it with the complete corresponding 0215 machine-readable source code, which must be distributed under the terms of 0216 Sections 1 and 2 above on a medium customarily used for software interchange. 0217 0218 If distribution of object code is made by offering access to copy from a designated 0219 place, then offering equivalent access to copy the source code from the same 0220 place satisfies the requirement to distribute the source code, even though 0221 third parties are not compelled to copy the source along with the object code. 0222 0223 5. A program that contains no derivative of any portion of the Library, but 0224 is designed to work with the Library by being compiled or linked with it, 0225 is called a "work that uses the Library". Such a work, in isolation, is not 0226 a derivative work of the Library, and therefore falls outside the scope of 0227 this License. 0228 0229 However, linking a "work that uses the Library" with the Library creates an 0230 executable that is a derivative of the Library (because it contains portions 0231 of the Library), rather than a "work that uses the library". The executable 0232 is therefore covered by this License. Section 6 states terms for distribution 0233 of such executables. 0234 0235 When a "work that uses the Library" uses material from a header file that 0236 is part of the Library, the object code for the work may be a derivative work 0237 of the Library even though the source code is not. Whether this is true is 0238 especially significant if the work can be linked without the Library, or if 0239 the work is itself a library. The threshold for this to be true is not precisely 0240 defined by law. 0241 0242 If such an object file uses only numerical parameters, data structure layouts 0243 and accessors, and small macros and small inline functions (ten lines or less 0244 in length), then the use of the object file is unrestricted, regardless of 0245 whether it is legally a derivative work. (Executables containing this object 0246 code plus portions of the Library will still fall under Section 6.) 0247 0248 Otherwise, if the work is a derivative of the Library, you may distribute 0249 the object code for the work under the terms of Section 6. Any executables 0250 containing that work also fall under Section 6, whether or not they are linked 0251 directly with the Library itself. 0252 0253 6. As an exception to the Sections above, you may also combine or link a "work 0254 that uses the Library" with the Library to produce a work containing portions 0255 of the Library, and distribute that work under terms of your choice, provided 0256 that the terms permit modification of the work for the customer's own use 0257 and reverse engineering for debugging such modifications. 0258 0259 You must give prominent notice with each copy of the work that the Library 0260 is used in it and that the Library and its use are covered by this License. 0261 You must supply a copy of this License. If the work during execution displays 0262 copyright notices, you must include the copyright notice for the Library among 0263 them, as well as a reference directing the user to the copy of this License. 0264 Also, you must do one of these things: 0265 0266 a) Accompany the work with the complete corresponding machine-readable source 0267 code for the Library including whatever changes were used in the work (which 0268 must be distributed under Sections 1 and 2 above); and, if the work is an 0269 executable linked with the Library, with the complete machine-readable "work 0270 that uses the Library", as object code and/or source code, so that the user 0271 can modify the Library and then relink to produce a modified executable containing 0272 the modified Library. (It is understood that the user who changes the contents 0273 of definitions files in the Library will not necessarily be able to recompile 0274 the application to use the modified definitions.) 0275 0276 b) Use a suitable shared library mechanism for linking with the Library. A 0277 suitable mechanism is one that (1) uses at run time a copy of the library 0278 already present on the user's computer system, rather than copying library 0279 functions into the executable, and (2) will operate properly with a modified 0280 version of the library, if the user installs one, as long as the modified 0281 version is interface-compatible with the version that the work was made with. 0282 0283 c) Accompany the work with a written offer, valid for at least three years, 0284 to give the same user the materials specified in Subsection 6a, above, for 0285 a charge no more than the cost of performing this distribution. 0286 0287 d) If distribution of the work is made by offering access to copy from a designated 0288 place, offer equivalent access to copy the above specified materials from 0289 the same place. 0290 0291 e) Verify that the user has already received a copy of these materials or 0292 that you have already sent this user a copy. 0293 0294 For an executable, the required form of the "work that uses the Library" must 0295 include any data and utility programs needed for reproducing the executable 0296 from it. However, as a special exception, the materials to be distributed 0297 need not include anything that is normally distributed (in either source or 0298 binary form) with the major components (compiler, kernel, and so on) of the 0299 operating system on which the executable runs, unless that component itself 0300 accompanies the executable. 0301 0302 It may happen that this requirement contradicts the license restrictions of 0303 other proprietary libraries that do not normally accompany the operating system. 0304 Such a contradiction means you cannot use both them and the Library together 0305 in an executable that you distribute. 0306 0307 7. You may place library facilities that are a work based on the Library side-by-side 0308 in a single library together with other library facilities not covered by 0309 this License, and distribute such a combined library, provided that the separate 0310 distribution of the work based on the Library and of the other library facilities 0311 is otherwise permitted, and provided that you do these two things: 0312 0313 a) Accompany the combined library with a copy of the same work based on the 0314 Library, uncombined with any other library facilities. This must be distributed 0315 under the terms of the Sections above. 0316 0317 b) Give prominent notice with the combined library of the fact that part of 0318 it is a work based on the Library, and explaining where to find the accompanying 0319 uncombined form of the same work. 0320 0321 8. You may not copy, modify, sublicense, link with, or distribute the Library 0322 except as expressly provided under this License. Any attempt otherwise to 0323 copy, modify, sublicense, link with, or distribute the Library is void, and 0324 will automatically terminate your rights under this License. However, parties 0325 who have received copies, or rights, from you under this License will not 0326 have their licenses terminated so long as such parties remain in full compliance. 0327 0328 9. You are not required to accept this License, since you have not signed 0329 it. However, nothing else grants you permission to modify or distribute the 0330 Library or its derivative works. These actions are prohibited by law if you 0331 do not accept this License. Therefore, by modifying or distributing the Library 0332 (or any work based on the Library), you indicate your acceptance of this License 0333 to do so, and all its terms and conditions for copying, distributing or modifying 0334 the Library or works based on it. 0335 0336 10. Each time you redistribute the Library (or any work based on the Library), 0337 the recipient automatically receives a license from the original licensor 0338 to copy, distribute, link with or modify the Library subject to these terms 0339 and conditions. You may not impose any further restrictions on the recipients' 0340 exercise of the rights granted herein. You are not responsible for enforcing 0341 compliance by third parties with this License. 0342 0343 11. If, as a consequence of a court judgment or allegation of patent infringement 0344 or for any other reason (not limited to patent issues), conditions are imposed 0345 on you (whether by court order, agreement or otherwise) that contradict the 0346 conditions of this License, they do not excuse you from the conditions of 0347 this License. If you cannot distribute so as to satisfy simultaneously your 0348 obligations under this License and any other pertinent obligations, then as 0349 a consequence you may not distribute the Library at all. For example, if a 0350 patent license would not permit royalty-free redistribution of the Library 0351 by all those who receive copies directly or indirectly through you, then the 0352 only way you could satisfy both it and this License would be to refrain entirely 0353 from distribution of the Library. 0354 0355 If any portion of this section is held invalid or unenforceable under any 0356 particular circumstance, the balance of the section is intended to apply, 0357 and the section as a whole is intended to apply in other circumstances. 0358 0359 It is not the purpose of this section to induce you to infringe any patents 0360 or other property right claims or to contest validity of any such claims; 0361 this section has the sole purpose of protecting the integrity of the free 0362 software distribution system which is implemented by public license practices. 0363 Many people have made generous contributions to the wide range of software 0364 distributed through that system in reliance on consistent application of that 0365 system; it is up to the author/donor to decide if he or she is willing to 0366 distribute software through any other system and a licensee cannot impose 0367 that choice. 0368 0369 This section is intended to make thoroughly clear what is believed to be a 0370 consequence of the rest of this License. 0371 0372 12. If the distribution and/or use of the Library is restricted in certain 0373 countries either by patents or by copyrighted interfaces, the original copyright 0374 holder who places the Library under this License may add an explicit geographical 0375 distribution limitation excluding those countries, so that distribution is 0376 permitted only in or among countries not thus excluded. In such case, this 0377 License incorporates the limitation as if written in the body of this License. 0378 0379 13. The Free Software Foundation may publish revised and/or new versions of 0380 the Lesser General Public License from time to time. Such new versions will 0381 be similar in spirit to the present version, but may differ in detail to address 0382 new problems or concerns. 0383 0384 Each version is given a distinguishing version number. If the Library specifies 0385 a version number of this License which applies to it and "any later version", 0386 you have the option of following the terms and conditions either of that version 0387 or of any later version published by the Free Software Foundation. If the 0388 Library does not specify a license version number, you may choose any version 0389 ever published by the Free Software Foundation. 0390 0391 14. If you wish to incorporate parts of the Library into other free programs 0392 whose distribution conditions are incompatible with these, write to the author 0393 to ask for permission. For software which is copyrighted by the Free Software 0394 Foundation, write to the Free Software Foundation; we sometimes make exceptions 0395 for this. Our decision will be guided by the two goals of preserving the free 0396 status of all derivatives of our free software and of promoting the sharing 0397 and reuse of software generally. 0398 0399 NO WARRANTY 0400 0401 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR 0402 THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE 0403 STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY 0404 "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, 0405 BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS 0406 FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE 0407 OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME 0408 THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 0409 0410 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 0411 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE 0412 THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY 0413 GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE 0414 OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA 0415 OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES 0416 OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH 0417 HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. 0418 0419 END OF TERMS AND CONDITIONS 0420 0421 How to Apply These Terms to Your New Libraries 0422 0423 If you develop a new library, and you want it to be of the greatest possible 0424 use to the public, we recommend making it free software that everyone can 0425 redistribute and change. You can do so by permitting redistribution under 0426 these terms (or, alternatively, under the terms of the ordinary General Public 0427 License). 0428 0429 To apply these terms, attach the following notices to the library. It is safest 0430 to attach them to the start of each source file to most effectively convey 0431 the exclusion of warranty; and each file should have at least the "copyright" 0432 line and a pointer to where the full notice is found. 0433 0434 one line to give the library's name and an idea of what it does. 0435 Copyright (C) year name of author 0436 0437 This library is free software; you can redistribute it and/or modify it under 0438 the terms of the GNU Lesser General Public License as published by the Free 0439 Software Foundation; either version 2.1 of the License, or (at your option) 0440 any later version. 0441 0442 This library is distributed in the hope that it will be useful, but WITHOUT 0443 ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS 0444 FOR A PARTICULAR PURPOSE. See the GNU Lesser General Public License for more 0445 details. 0446 0447 You should have received a copy of the GNU Lesser General Public License along 0448 with this library; if not, write to the Free Software Foundation, Inc., 51 0449 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA Also add information 0450 on how to contact you by electronic and paper mail. 0451 0452 You should also get your employer (if you work as a programmer) or your school, 0453 if any, to sign a "copyright disclaimer" for the library, if necessary. Here 0454 is a sample; alter the names: 0455 0456 Yoyodyne, Inc., hereby disclaims all copyright interest in 0457 the library `Frob' (a library for tweaking knobs) written 0458 by James Random Hacker. 0459 0460 signature of Ty Coon, 1 April 1990 0461 Ty Coon, President of Vice 0462 That's all there is to it!
