  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 Lesser GPL. It also counts
  11. as the successor of the GNU Library Public License, version 2, hence the
  12. version number 2.1.]
  13. @end display
  14. @appendixsubsec Preamble
  15. The licenses for most software are designed to take away your
  16. freedom to share and change it. By contrast, the GNU General Public
  17. Licenses are intended to guarantee your freedom to share and change
  18. free software---to make sure the software is free for all its users.
  19. This license, the Lesser General Public License, applies to some
  20. specially designated software---typically libraries---of the Free
  21. Software Foundation and other authors who decide to use it. You can use
  22. it too, but we suggest you first think carefully about whether this
  23. license or the ordinary General Public License is the better strategy to
  24. use in any particular case, based on the explanations below.
  25. When we speak of free software, we are referring to freedom of use,
  26. not price. Our General Public Licenses are designed to make sure that
  27. you have the freedom to distribute copies of free software (and charge
  28. for this service if you wish); that you receive source code or can get
  29. it if you want it; that you can change the software and use pieces of it
  30. in new free programs; and that you are informed that you can do these
  31. things.
  32. To protect your rights, we need to make restrictions that forbid
  33. distributors to deny you these rights or to ask you to surrender these
  34. rights. These restrictions translate to certain responsibilities for
  35. you if you distribute copies of the library or if you modify it.
  36. For example, if you distribute copies of the library, whether gratis
  37. or for a fee, you must give the recipients all the rights that we gave
  38. you. You must make sure that they, too, receive or can get the source
  39. code. If you link other code with the library, you must provide
  40. complete object files to the recipients, so that they can relink them
  41. with the library after making changes to the library and recompiling
  42. it. And you must show them these terms so they know their rights.
  43. We protect your rights with a two-step method: (1) we copyright the
  44. library, and (2) we offer you this license, which gives you legal
  45. permission to copy, distribute and/or modify the library.
  46. To protect each distributor, we want to make it very clear that
  47. there is no warranty for the free library. Also, if the library is
  48. modified by someone else and passed on, the recipients should know
  49. that what they have is not the original version, so that the original
  50. author's reputation will not be affected by problems that might be
  51. introduced by others.
  52. Finally, software patents pose a constant threat to the existence of
  53. any free program. We wish to make sure that a company cannot
  54. effectively restrict the users of a free program by obtaining a
  55. restrictive license from a patent holder. Therefore, we insist that
  56. any patent license obtained for a version of the library must be
  57. consistent with the full freedom of use specified in this license.
  58. Most GNU software, including some libraries, is covered by the
  59. ordinary GNU General Public License. This license, the GNU Lesser
  60. General Public License, applies to certain designated libraries, and
  61. is quite different from the ordinary General Public License. We use
  62. this license for certain libraries in order to permit linking those
  63. libraries into non-free programs.
  64. When a program is linked with a library, whether statically or using
  65. a shared library, the combination of the two is legally speaking a
  66. combined work, a derivative of the original library. The ordinary
  67. General Public License therefore permits such linking only if the
  68. entire combination fits its criteria of freedom. The Lesser General
  69. Public License permits more lax criteria for linking other code with
  70. the library.
  71. We call this license the @dfn{Lesser} General Public License because it
  72. does @emph{Less} to protect the user's freedom than the ordinary General
  73. Public License. It also provides other free software developers Less
  74. of an advantage over competing non-free programs. These disadvantages
  75. are the reason we use the ordinary General Public License for many
  76. libraries. However, the Lesser license provides advantages in certain
  77. special circumstances.
  78. For example, on rare occasions, there may be a special need to
  79. encourage the widest possible use of a certain library, so that it becomes
  80. a de-facto standard. To achieve this, non-free programs must be
  81. allowed to use the library. A more frequent case is that a free
  82. library does the same job as widely used non-free libraries. In this
  83. case, there is little to gain by limiting the free library to free
  84. software only, so we use the Lesser General Public License.
  85. In other cases, permission to use a particular library in non-free
  86. programs enables a greater number of people to use a large body of
  87. free software. For example, permission to use the GNU C Library in
  88. non-free programs enables many more people to use the whole GNU
  89. operating system, as well as its variant, the GNU/Linux operating
  90. system.
  91. Although the Lesser General Public License is Less protective of the
  92. users' freedom, it does ensure that the user of a program that is
  93. linked with the Library has the freedom and the wherewithal to run
  94. that program using a modified version of the Library.
  95. The precise terms and conditions for copying, distribution and
  96. modification follow. Pay close attention to the difference between a
  97. ``work based on the library'' and a ``work that uses the library''. The
  98. former contains code derived from the library, whereas the latter must
  99. be combined with the library in order to run.

  108. @item
  109. This License Agreement applies to any software library or other program
  110. which contains a notice placed by the copyright holder or other
  111. authorized party saying it may be distributed under the terms of this
  112. Lesser General Public License (also called ``this License''). Each
  113. licensee is addressed as ``you''.
  114. A ``library'' means a collection of software functions and/or data
  115. prepared so as to be conveniently linked with application programs
  116. (which use some of those functions and data) to form executables.
  117. The ``Library'', below, refers to any such software library or work
  118. which has been distributed under these terms. A ``work based on the
  119. Library'' means either the Library or any derivative work under
  120. copyright law: that is to say, a work containing the Library or a
  121. portion of it, either verbatim or with modifications and/or translated
  122. straightforwardly into another language. (Hereinafter, translation is
  123. included without limitation in the term ``modification''.)
  124. ``Source code'' for a work means the preferred form of the work for
  125. making modifications to it. For a library, complete source code means
  126. all the source code for all modules it contains, plus any associated
  127. interface definition files, plus the scripts used to control compilation
  128. and installation of the library.
  129. Activities other than copying, distribution and modification are not
  130. covered by this License; they are outside its scope. The act of
  131. running a program using the Library is not restricted, and output from
  132. such a program is covered only if its contents constitute a work based
  133. on the Library (independent of the use of the Library in a tool for
  134. writing it). Whether that is true depends on what the Library does
  135. and what the program that uses the Library does.
  136. @item
  137. You may copy and distribute verbatim copies of the Library's
  138. complete source code as you receive it, in any medium, provided that
  139. you conspicuously and appropriately publish on each copy an
  140. appropriate copyright notice and disclaimer of warranty; keep intact
  141. all the notices that refer to this License and to the absence of any
  142. warranty; and distribute a copy of this License along with the
  143. Library.
  144. You may charge a fee for the physical act of transferring a copy,
  145. and you may at your option offer warranty protection in exchange for a
  146. fee.
  147. @item
  148. You may modify your copy or copies of the Library or any portion
  149. of it, thus forming a work based on the Library, and copy and
  150. distribute such modifications or work under the terms of Section 1
  151. above, provided that you also meet all of these conditions:
  152. @enumerate a
  153. @item
  154. The modified work must itself be a software library.
  155. @item
  156. You must cause the files modified to carry prominent notices
  157. stating that you changed the files and the date of any change.
  158. @item
  159. You must cause the whole of the work to be licensed at no
  160. charge to all third parties under the terms of this License.
  161. @item
  162. If a facility in the modified Library refers to a function or a
  163. table of data to be supplied by an application program that uses
  164. the facility, other than as an argument passed when the facility
  165. is invoked, then you must make a good faith effort to ensure that,
  166. in the event an application does not supply such function or
  167. table, the facility still operates, and performs whatever part of
  168. its purpose remains meaningful.
  169. (For example, a function in a library to compute square roots has
  170. a purpose that is entirely well-defined independent of the
  171. application. Therefore, Subsection 2d requires that any
  172. application-supplied function or table used by this function must
  173. be optional: if the application does not supply it, the square
  174. root function must still compute square roots.)
  175. @end enumerate
  176. These requirements apply to the modified work as a whole. If
  177. identifiable sections of that work are not derived from the Library,
  178. and can be reasonably considered independent and separate works in
  179. themselves, then this License, and its terms, do not apply to those
  180. sections when you distribute them as separate works. But when you
  181. distribute the same sections as part of a whole which is a work based
  182. on the Library, the distribution of the whole must be on the terms of
  183. this License, whose permissions for other licensees extend to the
  184. entire whole, and thus to each and every part regardless of who wrote
  185. it.
  186. Thus, it is not the intent of this section to claim rights or contest
  187. your rights to work written entirely by you; rather, the intent is to
  188. exercise the right to control the distribution of derivative or
  189. collective works based on the Library.
  190. In addition, mere aggregation of another work not based on the Library
  191. with the Library (or with a work based on the Library) on a volume of
  192. a storage or distribution medium does not bring the other work under
  193. the scope of this License.
  194. @item
  195. You may opt to apply the terms of the ordinary GNU General Public
  196. License instead of this License to a given copy of the Library. To do
  197. this, you must alter all the notices that refer to this License, so
  198. that they refer to the ordinary GNU General Public License, version 2,
  199. instead of to this License. (If a newer version than version 2 of the
  200. ordinary GNU General Public License has appeared, then you can specify
  201. that version instead if you wish.) Do not make any other change in
  202. these notices.
  203. Once this change is made in a given copy, it is irreversible for
  204. that copy, so the ordinary GNU General Public License applies to all
  205. subsequent copies and derivative works made from that copy.
  206. This option is useful when you wish to copy part of the code of
  207. the Library into a program that is not a library.
  208. @item
  209. You may copy and distribute the Library (or a portion or
  210. derivative of it, under Section 2) in object code or executable form
  211. under the terms of Sections 1 and 2 above provided that you accompany
  212. it with the complete corresponding machine-readable source code, which
  213. must be distributed under the terms of Sections 1 and 2 above on a
  214. medium customarily used for software interchange.
  215. If distribution of object code is made by offering access to copy
  216. from a designated place, then offering equivalent access to copy the
  217. source code from the same place satisfies the requirement to
  218. distribute the source code, even though third parties are not
  219. compelled to copy the source along with the object code.
  220. @item
  221. A program that contains no derivative of any portion of the
  222. Library, but is designed to work with the Library by being compiled or
  223. linked with it, is called a ``work that uses the Library''. Such a
  224. work, in isolation, is not a derivative work of the Library, and
  225. therefore falls outside the scope of this License.
  226. However, linking a ``work that uses the Library'' with the Library
  227. creates an executable that is a derivative of the Library (because it
  228. contains portions of the Library), rather than a ``work that uses the
  229. library''. The executable is therefore covered by this License.
  230. Section 6 states terms for distribution of such executables.
  231. When a ``work that uses the Library'' uses material from a header file
  232. that is part of the Library, the object code for the work may be a
  233. derivative work of the Library even though the source code is not.
  234. Whether this is true is especially significant if the work can be
  235. linked without the Library, or if the work is itself a library. The
  236. threshold for this to be true is not precisely defined by law.
  237. If such an object file uses only numerical parameters, data
  238. structure layouts and accessors, and small macros and small inline
  239. functions (ten lines or less in length), then the use of the object
  240. file is unrestricted, regardless of whether it is legally a derivative
  241. work. (Executables containing this object code plus portions of the
  242. Library will still fall under Section 6.)
  243. Otherwise, if the work is a derivative of the Library, you may
  244. distribute the object code for the work under the terms of Section 6.
  245. Any executables containing that work also fall under Section 6,
  246. whether or not they are linked directly with the Library itself.
  247. @item
  248. As an exception to the Sections above, you may also combine or
  249. link a ``work that uses the Library'' with the Library to produce a
  250. work containing portions of the Library, and distribute that work
  251. under terms of your choice, provided that the terms permit
  252. modification of the work for the customer's own use and reverse
  253. engineering for debugging such modifications.
  254. You must give prominent notice with each copy of the work that the
  255. Library is used in it and that the Library and its use are covered by
  256. this License. You must supply a copy of this License. If the work
  257. during execution displays copyright notices, you must include the
  258. copyright notice for the Library among them, as well as a reference
  259. directing the user to the copy of this License. Also, you must do one
  260. of these things:
  261. @enumerate a
  262. @item
  263. Accompany the work with the complete corresponding
  264. machine-readable source code for the Library including whatever
  265. changes were used in the work (which must be distributed under
  266. Sections 1 and 2 above); and, if the work is an executable linked
  267. with the Library, with the complete machine-readable ``work that
  268. uses the Library'', as object code and/or source code, so that the
  269. user can modify the Library and then relink to produce a modified
  270. executable containing the modified Library. (It is understood
  271. that the user who changes the contents of definitions files in the
  272. Library will not necessarily be able to recompile the application
  273. to use the modified definitions.)
  274. @item
  275. Use a suitable shared library mechanism for linking with the Library. A
  276. suitable mechanism is one that (1) uses at run time a copy of the
  277. library already present on the user's computer system, rather than
  278. copying library functions into the executable, and (2) will operate
  279. properly with a modified version of the library, if the user installs
  280. one, as long as the modified version is interface-compatible with the
  281. version that the work was made with.
  282. @item
  283. Accompany the work with a written offer, valid for at
  284. least three years, to give the same user the materials
  285. specified in Subsection 6a, above, for a charge no more
  286. than the cost of performing this distribution.
  287. @item
  288. If distribution of the work is made by offering access to copy
  289. from a designated place, offer equivalent access to copy the above
  290. specified materials from the same place.
  291. @item
  292. Verify that the user has already received a copy of these
  293. materials or that you have already sent this user a copy.
  294. @end enumerate
  295. For an executable, the required form of the ``work that uses the
  296. Library'' must include any data and utility programs needed for
  297. reproducing the executable from it. However, as a special exception,
  298. the materials to be distributed need not include anything that is
  299. normally distributed (in either source or binary form) with the major
  300. components (compiler, kernel, and so on) of the operating system on
  301. which the executable runs, unless that component itself accompanies the
  302. executable.
  303. It may happen that this requirement contradicts the license
  304. restrictions of other proprietary libraries that do not normally
  305. accompany the operating system. Such a contradiction means you cannot
  306. use both them and the Library together in an executable that you
  307. distribute.
  308. @item
  309. You may place library facilities that are a work based on the
  310. Library side-by-side in a single library together with other library
  311. facilities not covered by this License, and distribute such a combined
  312. library, provided that the separate distribution of the work based on
  313. the Library and of the other library facilities is otherwise
  314. permitted, and provided that you do these two things:
  315. @enumerate a
  316. @item
  317. Accompany the combined library with a copy of the same work
  318. based on the Library, uncombined with any other library
  319. facilities. This must be distributed under the terms of the
  320. Sections above.
  321. @item
  322. Give prominent notice with the combined library of the fact
  323. that part of it is a work based on the Library, and explaining
  324. where to find the accompanying uncombined form of the same work.

  326. @item
  327. You may not copy, modify, sublicense, link with, or distribute
  328. the Library except as expressly provided under this License. Any
  329. attempt otherwise to copy, modify, sublicense, link with, or
  330. distribute the Library is void, and will automatically terminate your
  331. rights under this License. However, parties who have received copies,
  332. or rights, from you under this License will not have their licenses
  333. terminated so long as such parties remain in full compliance.
  334. @item
  335. You are not required to accept this License, since you have not
  336. signed it. However, nothing else grants you permission to modify or
  337. distribute the Library or its derivative works. These actions are
  338. prohibited by law if you do not accept this License. Therefore, by
  339. modifying or distributing the Library (or any work based on the
  340. Library), you indicate your acceptance of this License to do so, and
  341. all its terms and conditions for copying, distributing or modifying
  342. the Library or works based on it.
  343. @item
  344. Each time you redistribute the Library (or any work based on the
  345. Library), the recipient automatically receives a license from the
  346. original licensor to copy, distribute, link with or modify the Library

  348. restrictions on the recipients' exercise of the rights granted herein.
  349. You are not responsible for enforcing compliance by third parties with
  350. this License.

  352. If, as a consequence of a court judgment or allegation of patent
  353. infringement or for any other reason (not limited to patent issues),
  354. conditions are imposed on you (whether by court order, agreement or
  355. otherwise) that contradict the conditions of this License, they do not
  356. excuse you from the conditions of this License. If you cannot
  357. distribute so as to satisfy simultaneously your obligations under this
  358. License and any other pertinent obligations, then as a consequence you
  359. may not distribute the Library at all. For example, if a patent
  360. license would not permit royalty-free redistribution of the Library by
  361. all those who receive copies directly or indirectly through you, then
  362. the only way you could satisfy both it and this License would be to
  363. refrain entirely from distribution of the Library.
  364. If any portion of this section is held invalid or unenforceable under any
  365. particular circumstance, the balance of the section is intended to apply,
  366. and the section as a whole is intended to apply in other circumstances.
  367. It is not the purpose of this section to induce you to infringe any
  368. patents or other property right claims or to contest validity of any
  369. such claims; this section has the sole purpose of protecting the
  370. integrity of the free software distribution system which is
  371. implemented by public license practices. Many people have made
  372. generous contributions to the wide range of software distributed
  373. through that system in reliance on consistent application of that
  374. system; it is up to the author/donor to decide if he or she is willing
  375. to distribute software through any other system and a licensee cannot
  376. impose that choice.
  377. This section is intended to make thoroughly clear what is believed to
  378. be a consequence of the rest of this License.

  380. If the distribution and/or use of the Library is restricted in
  381. certain countries either by patents or by copyrighted interfaces, the
  382. original copyright holder who places the Library under this License may add
  383. an explicit geographical distribution limitation excluding those countries,
  384. so that distribution is permitted only in or among countries not thus
  385. excluded. In such case, this License incorporates the limitation as if
  386. written in the body of this License.

  388. The Free Software Foundation may publish revised and/or new
  389. versions of the Lesser General Public License from time to time.
  390. Such new versions will be similar in spirit to the present version,
  391. but may differ in detail to address new problems or concerns.
  392. Each version is given a distinguishing version number. If the Library
  393. specifies a version number of this License which applies to it and
  394. ``any later version'', you have the option of following the terms and
  395. conditions either of that version or of any later version published by
  396. the Free Software Foundation. If the Library does not specify a
  397. license version number, you may choose any version ever published by
  398. the Free Software Foundation.
  399. @item
  400. If you wish to incorporate parts of the Library into other free
  401. programs whose distribution conditions are incompatible with these,
  402. write to the author to ask for permission. For software which is
  403. copyrighted by the Free Software Foundation, write to the Free
  404. Software Foundation; we sometimes make exceptions for this. Our
  405. decision will be guided by the two goals of preserving the free status
  406. of all derivatives of our free software and of promoting the sharing
  407. and reuse of software generally.
  408. @center NO WARRANTY

  410. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
  411. WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
  412. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
  413. OTHER PARTIES PROVIDE THE LIBRARY ``AS IS'' WITHOUT WARRANTY OF ANY
  414. KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
  415. IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
  416. PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE

  423. FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
  424. CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
  425. LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
  426. RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
  427. FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF

  438. @appendixsubsec How to Apply These Terms to Your New Libraries
  439. If you develop a new library, and you want it to be of the greatest
  440. possible use to the public, we recommend making it free software that
  441. everyone can redistribute and change. You can do so by permitting
  442. redistribution under these terms (or, alternatively, under the terms of the
  443. ordinary General Public License).
  444. To apply these terms, attach the following notices to the library. It is
  445. safest to attach them to the start of each source file to most effectively
  446. convey the exclusion of warranty; and each file should have at least the
  447. ``copyright'' line and a pointer to where the full notice is found.

  464. Also add information on how to contact you by electronic and paper mail.
  465. You should also get your employer (if you work as a programmer) or your
  466. school, if any, to sign a ``copyright disclaimer'' for the library, if
  467. necessary. Here is a sample; alter the names:
