  4. GNU LIBRARY GENERAL PUBLIC LICENSE
  5. Version 2, June 1991
  6. Copyright (C) 1991 Free Software Foundation, Inc.
  7. 675 Mass Ave, Cambridge, MA 02139, USA
  8. Everyone is permitted to copy and distribute verbatim copies
  9. of this license document, but changing it is not allowed.
  10. [This is the first released version of the library GPL. It is
  11. numbered 2 because it goes with version 2 of the ordinary GPL.]
  12. Preamble
  13. The licenses for most software are designed to take away your
  14. freedom to share and change it. By contrast, the GNU General Public
  15. Licenses are intended to guarantee your freedom to share and change
  16. free software--to make sure the software is free for all its users.
  17. This license, the Library General Public License, applies to some
  18. specially designated Free Software Foundation software, and to any
  19. other libraries whose authors decide to use it. You can use it for
  20. your libraries, too.
  21. When we speak of free software, we are referring to freedom, not
  22. price. Our General Public Licenses are designed to make sure that you
  23. have the freedom to distribute copies of free software (and charge for
  24. this service if you wish), that you receive source code or can get it
  25. if you want it, that you can change the software or use pieces of it
  26. in new free programs; and that you know you can do these things.
  27. To protect your rights, we need to make restrictions that forbid
  28. anyone to deny you these rights or to ask you to surrender the rights.
  29. These restrictions translate to certain responsibilities for you if
  30. you distribute copies of the library, or if you modify it.
  31. For example, if you distribute copies of the library, whether gratis
  32. or for a fee, you must give the recipients all the rights that we gave
  33. you. You must make sure that they, too, receive or can get the source
  34. code. If you link a program with the library, you must provide
  35. complete object files to the recipients so that they can relink them
  36. with the library, after making changes to the library and recompiling
  37. it. And you must show them these terms so they know their rights.
  38. Our method of protecting your rights has two steps: (1) copyright
  39. the library, and (2) offer you this license which gives you legal
  40. permission to copy, distribute and/or modify the library.
  41. Also, for each distributor's protection, we want to make certain
  42. that everyone understands that there is no warranty for this free
  43. library. If the library is modified by someone else and passed on, we
  44. want its recipients to know that what they have is not the original
  45. version, so that any problems introduced by others will not reflect on
  46. the original authors' reputations.
  47. Finally, any free program is threatened constantly by software
  48. patents. We wish to avoid the danger that companies distributing free
  49. software will individually obtain patent licenses, thus in effect
  50. transforming the program into proprietary software. To prevent this,
  51. we have made it clear that any patent must be licensed for everyone's
  52. free use or not licensed at all.
  53. Most GNU software, including some libraries, is covered by the ordinary
  54. GNU General Public License, which was designed for utility programs. This
  55. license, the GNU Library General Public License, applies to certain
  56. designated libraries. This license is quite different from the ordinary
  57. one; be sure to read it in full, and don't assume that anything in it is
  58. the same as in the ordinary license.
  59. The reason we have a separate public license for some libraries is that
  60. they blur the distinction we usually make between modifying or adding to a
  61. program and simply using it. Linking a program with a library, without
  62. changing the library, is in some sense simply using the library, and is
  63. analogous to running a utility program or application program. However, in
  64. a textual and legal sense, the linked executable is a combined work, a
  65. derivative of the original library, and the ordinary General Public License
  66. treats it as such.
  67. Because of this blurred distinction, using the ordinary General
  68. Public License for libraries did not effectively promote software
  69. sharing, because most developers did not use the libraries. We
  70. concluded that weaker conditions might promote sharing better.
  71. However, unrestricted linking of non-free programs would deprive the
  72. users of those programs of all benefit from the free status of the
  73. libraries themselves. This Library General Public License is intended to
  74. permit developers of non-free programs to use free libraries, while
  75. preserving your freedom as a user of such programs to change the free
  76. libraries that are incorporated in them. (We have not seen how to achieve
  77. this as regards changes in header files, but we have achieved it as regards
  78. changes in the actual functions of the Library.) The hope is that this
  79. will lead to faster development of free libraries.
  80. The precise terms and conditions for copying, distribution and
  81. modification follow. Pay close attention to the difference between a
  82. "work based on the library" and a "work that uses the library". The
  83. former contains code derived from the library, while the latter only
  84. works together with the library.
  85. Note that it is possible for a library to be covered by the ordinary
  86. General Public License rather than by this special one.
  87. GNU LIBRARY GENERAL PUBLIC LICENSE
  88. TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
  89. 0. This License Agreement applies to any software library which
  90. contains a notice placed by the copyright holder or other authorized
  91. party saying it may be distributed under the terms of this Library
  92. General Public License (also called "this License"). Each licensee is
  93. addressed as "you".
  94. A "library" means a collection of software functions and/or data
  95. prepared so as to be conveniently linked with application programs
  96. (which use some of those functions and data) to form executables.
  97. The "Library", below, refers to any such software library or work
  98. which has been distributed under these terms. A "work based on the
  99. Library" means either the Library or any derivative work under
  100. copyright law: that is to say, a work containing the Library or a
  101. portion of it, either verbatim or with modifications and/or translated
  102. straightforwardly into another language. (Hereinafter, translation is
  103. included without limitation in the term "modification".)
  104. "Source code" for a work means the preferred form of the work for
  105. making modifications to it. For a library, complete source code means
  106. all the source code for all modules it contains, plus any associated
  107. interface definition files, plus the scripts used to control compilation
  108. and installation of the library.
  109. Activities other than copying, distribution and modification are not
  110. covered by this License; they are outside its scope. The act of
  111. running a program using the Library is not restricted, and output from
  112. such a program is covered only if its contents constitute a work based
  113. on the Library (independent of the use of the Library in a tool for
  114. writing it). Whether that is true depends on what the Library does
  115. and what the program that uses the Library does.
  116. 1. You may copy and distribute verbatim copies of the Library's
  117. complete source code as you receive it, in any medium, provided that
  118. you conspicuously and appropriately publish on each copy an
  119. appropriate copyright notice and disclaimer of warranty; keep intact
  120. all the notices that refer to this License and to the absence of any
  121. warranty; and distribute a copy of this License along with the
  122. Library.
  123. You may charge a fee for the physical act of transferring a copy,
  124. and you may at your option offer warranty protection in exchange for a
  125. fee.
  126. 2. You may modify your copy or copies of the Library or any portion
  127. of it, thus forming a work based on the Library, and copy and
  128. distribute such modifications or work under the terms of Section 1
  129. above, provided that you also meet all of these conditions:
  130. a) The modified work must itself be a software library.
  131. b) You must cause the files modified to carry prominent notices
  132. stating that you changed the files and the date of any change.
  133. c) You must cause the whole of the work to be licensed at no
  134. charge to all third parties under the terms of this License.
  135. d) If a facility in the modified Library refers to a function or a
  136. table of data to be supplied by an application program that uses
  137. the facility, other than as an argument passed when the facility
  138. is invoked, then you must make a good faith effort to ensure that,
  139. in the event an application does not supply such function or
  140. table, the facility still operates, and performs whatever part of
  141. its purpose remains meaningful.
  142. (For example, a function in a library to compute square roots has
  143. a purpose that is entirely well-defined independent of the
  144. application. Therefore, Subsection 2d requires that any
  145. application-supplied function or table used by this function must
  146. be optional: if the application does not supply it, the square
  147. root function must still compute square roots.)
  148. These requirements apply to the modified work as a whole. If
  149. identifiable sections of that work are not derived from the Library,
  150. and can be reasonably considered independent and separate works in
  151. themselves, then this License, and its terms, do not apply to those
  152. sections when you distribute them as separate works. But when you
  153. distribute the same sections as part of a whole which is a work based
  154. on the Library, the distribution of the whole must be on the terms of
  155. this License, whose permissions for other licensees extend to the
  156. entire whole, and thus to each and every part regardless of who wrote
  157. it.
  158. Thus, it is not the intent of this section to claim rights or contest
  159. your rights to work written entirely by you; rather, the intent is to
  160. exercise the right to control the distribution of derivative or
  161. collective works based on the Library.
  162. In addition, mere aggregation of another work not based on the Library
  163. with the Library (or with a work based on the Library) on a volume of
  164. a storage or distribution medium does not bring the other work under
  165. the scope of this License.
  166. 3. You may opt to apply the terms of the ordinary GNU General Public
  167. License instead of this License to a given copy of the Library. To do
  168. this, you must alter all the notices that refer to this License, so
  169. that they refer to the ordinary GNU General Public License, version 2,
  170. instead of to this License. (If a newer version than version 2 of the
  171. ordinary GNU General Public License has appeared, then you can specify
  172. that version instead if you wish.) Do not make any other change in
  173. these notices.
  174. Once this change is made in a given copy, it is irreversible for
  175. that copy, so the ordinary GNU General Public License applies to all
  176. subsequent copies and derivative works made from that copy.
  177. This option is useful when you wish to copy part of the code of
  178. the Library into a program that is not a library.
  179. 4. You may copy and distribute the Library (or a portion or
  180. derivative of it, under Section 2) in object code or executable form
  181. under the terms of Sections 1 and 2 above provided that you accompany
  182. it with the complete corresponding machine-readable source code, which
  183. must be distributed under the terms of Sections 1 and 2 above on a
  184. medium customarily used for software interchange.
  185. If distribution of object code is made by offering access to copy
  186. from a designated place, then offering equivalent access to copy the
  187. source code from the same place satisfies the requirement to
  188. distribute the source code, even though third parties are not
  189. compelled to copy the source along with the object code.
  190. 5. A program that contains no derivative of any portion of the
  191. Library, but is designed to work with the Library by being compiled or
  192. linked with it, is called a "work that uses the Library". Such a
  193. work, in isolation, is not a derivative work of the Library, and
  194. therefore falls outside the scope of this License.
  195. However, linking a "work that uses the Library" with the Library
  196. creates an executable that is a derivative of the Library (because it
  197. contains portions of the Library), rather than a "work that uses the
  198. library". The executable is therefore covered by this License.
  199. Section 6 states terms for distribution of such executables.
  200. When a "work that uses the Library" uses material from a header file
  201. that is part of the Library, the object code for the work may be a
  202. derivative work of the Library even though the source code is not.
  203. Whether this is true is especially significant if the work can be
  204. linked without the Library, or if the work is itself a library. The
  205. threshold for this to be true is not precisely defined by law.
  206. If such an object file uses only numerical parameters, data
  207. structure layouts and accessors, and small macros and small inline
  208. functions (ten lines or less in length), then the use of the object
  209. file is unrestricted, regardless of whether it is legally a derivative
  210. work. (Executables containing this object code plus portions of the
  211. Library will still fall under Section 6.)
  212. Otherwise, if the work is a derivative of the Library, you may
  213. distribute the object code for the work under the terms of Section 6.
  214. Any executables containing that work also fall under Section 6,
  215. whether or not they are linked directly with the Library itself.
  216. 6. As an exception to the Sections above, you may also compile or
  217. link a "work that uses the Library" with the Library to produce a
  218. work containing portions of the Library, and distribute that work
  219. under terms of your choice, provided that the terms permit
  220. modification of the work for the customer's own use and reverse
  221. engineering for debugging such modifications.
  222. You must give prominent notice with each copy of the work that the
  223. Library is used in it and that the Library and its use are covered by
  224. this License. You must supply a copy of this License. If the work
  225. during execution displays copyright notices, you must include the
  226. copyright notice for the Library among them, as well as a reference
  227. directing the user to the copy of this License. Also, you must do one
  228. of these things:
  229. a) Accompany the work with the complete corresponding
  230. machine-readable source code for the Library including whatever
  231. changes were used in the work (which must be distributed under
  232. Sections 1 and 2 above); and, if the work is an executable linked
  233. with the Library, with the complete machine-readable "work that
  234. uses the Library", as object code and/or source code, so that the
  235. user can modify the Library and then relink to produce a modified
  236. executable containing the modified Library. (It is understood
  237. that the user who changes the contents of definitions files in the
  238. Library will not necessarily be able to recompile the application
  239. to use the modified definitions.)
  240. b) Accompany the work with a written offer, valid for at
  241. least three years, to give the same user the materials
  242. specified in Subsection 6a, above, for a charge no more
  243. than the cost of performing this distribution.
  244. c) If distribution of the work is made by offering access to copy
  245. from a designated place, offer equivalent access to copy the above
  246. specified materials from the same place.
  247. d) Verify that the user has already received a copy of these
  248. materials or that you have already sent this user a copy.
  249. For an executable, the required form of the "work that uses the
  250. Library" must include any data and utility programs needed for
  251. reproducing the executable from it. However, as a special exception,
  252. the source code distributed need not include anything that is normally
  253. distributed (in either source or binary form) with the major
  254. components (compiler, kernel, and so on) of the operating system on
  255. which the executable runs, unless that component itself accompanies
  256. the executable.
  257. It may happen that this requirement contradicts the license
  258. restrictions of other proprietary libraries that do not normally
  259. accompany the operating system. Such a contradiction means you cannot
  260. use both them and the Library together in an executable that you
  261. distribute.
  262. 7. You may place library facilities that are a work based on the
  263. Library side-by-side in a single library together with other library
  264. facilities not covered by this License, and distribute such a combined
  265. library, provided that the separate distribution of the work based on
  266. the Library and of the other library facilities is otherwise
  267. permitted, and provided that you do these two things:
  268. a) Accompany the combined library with a copy of the same work
  269. based on the Library, uncombined with any other library
  270. facilities. This must be distributed under the terms of the
  271. Sections above.
  272. b) Give prominent notice with the combined library of the fact
  273. that part of it is a work based on the Library, and explaining
  274. where to find the accompanying uncombined form of the same work.
  275. 8. You may not copy, modify, sublicense, link with, or distribute
  276. the Library except as expressly provided under this License. Any
  277. attempt otherwise to copy, modify, sublicense, link with, or
  278. distribute the Library is void, and will automatically terminate your
  279. rights under this License. However, parties who have received copies,
  280. or rights, from you under this License will not have their licenses
  281. terminated so long as such parties remain in full compliance.
  282. 9. You are not required to accept this License, since you have not
  283. signed it. However, nothing else grants you permission to modify or
  284. distribute the Library or its derivative works. These actions are
  285. prohibited by law if you do not accept this License. Therefore, by
  286. modifying or distributing the Library (or any work based on the
  287. Library), you indicate your acceptance of this License to do so, and
  288. all its terms and conditions for copying, distributing or modifying
  289. the Library or works based on it.
  290. 10. Each time you redistribute the Library (or any work based on the
  291. Library), the recipient automatically receives a license from the
  292. original licensor to copy, distribute, link with or modify the Library
  293. subject to these terms and conditions. You may not impose any further
  294. restrictions on the recipients' exercise of the rights granted herein.
  295. You are not responsible for enforcing compliance by third parties to
  296. this License.
  297. 11. If, as a consequence of a court judgment or allegation of patent
  298. infringement or for any other reason (not limited to patent issues),
  299. conditions are imposed on you (whether by court order, agreement or
  300. otherwise) that contradict the conditions of this License, they do not
  301. excuse you from the conditions of this License. If you cannot
  302. distribute so as to satisfy simultaneously your obligations under this
  303. License and any other pertinent obligations, then as a consequence you
  304. may not distribute the Library at all. For example, if a patent
  305. license would not permit royalty-free redistribution of the Library by
  306. all those who receive copies directly or indirectly through you, then
  307. the only way you could satisfy both it and this License would be to
  308. refrain entirely from distribution of the Library.
  309. If any portion of this section is held invalid or unenforceable under any
  310. particular circumstance, the balance of the section is intended to apply,
  311. and the section as a whole is intended to apply in other circumstances.
  312. It is not the purpose of this section to induce you to infringe any
  313. patents or other property right claims or to contest validity of any
  314. such claims; this section has the sole purpose of protecting the
  315. integrity of the free software distribution system which is
  316. implemented by public license practices. Many people have made
  317. generous contributions to the wide range of software distributed
  318. through that system in reliance on consistent application of that
  319. system; it is up to the author/donor to decide if he or she is willing
  320. to distribute software through any other system and a licensee cannot
  321. impose that choice.
  322. This section is intended to make thoroughly clear what is believed to
  323. be a consequence of the rest of this License.
  324. 12. If the distribution and/or use of the Library is restricted in
  325. certain countries either by patents or by copyrighted interfaces, the
  326. original copyright holder who places the Library under this License may add
  327. an explicit geographical distribution limitation excluding those countries,
  328. so that distribution is permitted only in or among countries not thus
  329. excluded. In such case, this License incorporates the limitation as if
  330. written in the body of this License.
  331. 13. The Free Software Foundation may publish revised and/or new
  332. versions of the Library General Public License from time to time.
  333. Such new versions will be similar in spirit to the present version,
  334. but may differ in detail to address new problems or concerns.
  335. Each version is given a distinguishing version number. If the Library
  336. specifies a version number of this License which applies to it and
  337. "any later version", you have the option of following the terms and
  338. conditions either of that version or of any later version published by
  339. the Free Software Foundation. If the Library does not specify a
  340. license version number, you may choose any version ever published by
  341. the Free Software Foundation.
  342. 14. If you wish to incorporate parts of the Library into other free
  343. programs whose distribution conditions are incompatible with these,
  344. write to the author to ask for permission. For software which is
  345. copyrighted by the Free Software Foundation, write to the Free
  346. Software Foundation; we sometimes make exceptions for this. Our
  347. decision will be guided by the two goals of preserving the free status
  348. of all derivatives of our free software and of promoting the sharing
  349. and reuse of software generally.
  350. NO WARRANTY
  351. 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
  352. WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
  353. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
  354. OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
  355. KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
  356. IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
  357. PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
  358. LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
  359. THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
  360. 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
  361. WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
  362. AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
  363. FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
  364. CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
  365. LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
  366. RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
  367. FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
  368. SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
  369. DAMAGES.
  370. END OF TERMS AND CONDITIONS
  371. Appendix: How to Apply These Terms to Your New Libraries
  372. If you develop a new library, and you want it to be of the greatest
  373. possible use to the public, we recommend making it free software that
  374. everyone can redistribute and change. You can do so by permitting
  375. redistribution under these terms (or, alternatively, under the terms of the
  376. ordinary General Public License).
  377. To apply these terms, attach the following notices to the library. It is
  378. safest to attach them to the start of each source file to most effectively
  379. convey the exclusion of warranty; and each file should have at least the
  380. "copyright" line and a pointer to where the full notice is found.
  381. <one line to give the library's name and a brief idea of what it does.>
  382. Copyright (C) <year> <name of author>
  383. This library is free software; you can redistribute it and/or
  384. modify it under the terms of the GNU Library General Public
  385. License as published by the Free Software Foundation; either
  386. version 2 of the License, or (at your option) any later version.
  387. This library is distributed in the hope that it will be useful,
  388. but WITHOUT ANY WARRANTY; without even the implied warranty of
  389. MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
  390. Library General Public License for more details.
  391. You should have received a copy of the GNU Library General Public
  392. License along with this library; if not, write to the Free
  393. Software Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
  394. Also add information on how to contact you by electronic and paper mail.
  395. You should also get your employer (if you work as a programmer) or your
  396. school, if any, to sign a "copyright disclaimer" for the library, if
  397. necessary. Here is a sample; alter the names:
  398. Yoyodyne, Inc., hereby disclaims all copyright interest in the
  399. library `Frob' (a library for tweaking knobs) written by James Random Hacker.
  400. <signature of Ty Coon>, 1 April 1990
  401. Ty Coon, President of Vice
  402. That's all there is to it!
