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