  20. GNU LESSER GENERAL PUBLIC LICENSE
  21. Version 2.1, February 1999
  22. Copyright (C) 1991, 1999 Free Software Foundation, Inc.
  23. 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
  24. Everyone is permitted to copy and distribute verbatim copies
  25. of this license document, but changing it is not allowed.
  26. [This is the first released version of the Lesser GPL. It also counts
  27. as the successor of the GNU Library Public License, version 2, hence
  28. the version number 2.1.]
  29. Preamble
  30. The licenses for most software are designed to take away your
  31. freedom to share and change it. By contrast, the GNU General Public
  32. Licenses are intended to guarantee your freedom to share and change
  33. free software--to make sure the software is free for all its users.
  34. This license, the Lesser General Public License, applies to some
  35. specially designated software packages--typically libraries--of the
  36. Free Software Foundation and other authors who decide to use it. You
  37. can use it too, but we suggest you first think carefully about whether
  38. this license or the ordinary General Public License is the better
  39. strategy to use in any particular case, based on the explanations below.
  40. When we speak of free software, we are referring to freedom of use,
  41. not price. Our General Public Licenses are designed to make sure that
  42. you have the freedom to distribute copies of free software (and charge
  43. for this service if you wish); that you receive source code or can get
  44. it if you want it; that you can change the software and use pieces of
  45. it in new free programs; and that you are informed that you can do
  46. these things.
  47. To protect your rights, we need to make restrictions that forbid
  48. distributors to deny you these rights or to ask you to surrender these
  49. rights. These restrictions translate to certain responsibilities for
  50. you if you distribute copies of the library or if you modify it.
  51. For example, if you distribute copies of the library, whether gratis
  52. or for a fee, you must give the recipients all the rights that we gave
  53. you. You must make sure that they, too, receive or can get the source
  54. code. If you link other code with the library, you must provide
  55. complete object files to the recipients, so that they can relink them
  56. with the library after making changes to the library and recompiling
  57. it. And you must show them these terms so they know their rights.
  58. We protect your rights with a two-step method: (1) we copyright the
  59. library, and (2) we offer you this license, which gives you legal
  60. permission to copy, distribute and/or modify the library.
  61. To protect each distributor, we want to make it very clear that
  62. there is no warranty for the free library. Also, if the library is
  63. modified by someone else and passed on, the recipients should know
  64. that what they have is not the original version, so that the original
  65. author's reputation will not be affected by problems that might be
  66. introduced by others.
  67. Finally, software patents pose a constant threat to the existence of
  68. any free program. We wish to make sure that a company cannot
  69. effectively restrict the users of a free program by obtaining a
  70. restrictive license from a patent holder. Therefore, we insist that
  71. any patent license obtained for a version of the library must be
  72. consistent with the full freedom of use specified in this license.
  73. Most GNU software, including some libraries, is covered by the
  74. ordinary GNU General Public License. This license, the GNU Lesser
  75. General Public License, applies to certain designated libraries, and
  76. is quite different from the ordinary General Public License. We use
  77. this license for certain libraries in order to permit linking those
  78. libraries into non-free programs.
  79. When a program is linked with a library, whether statically or using
  80. a shared library, the combination of the two is legally speaking a
  81. combined work, a derivative of the original library. The ordinary
  82. General Public License therefore permits such linking only if the
  83. entire combination fits its criteria of freedom. The Lesser General
  84. Public License permits more lax criteria for linking other code with
  85. the library.
  86. We call this license the "Lesser" General Public License because it
  87. does Less to protect the user's freedom than the ordinary General
  88. Public License. It also provides other free software developers Less
  89. of an advantage over competing non-free programs. These disadvantages
  90. are the reason we use the ordinary General Public License for many
  91. libraries. However, the Lesser license provides advantages in certain
  92. special circumstances.
  93. For example, on rare occasions, there may be a special need to
  94. encourage the widest possible use of a certain library, so that it becomes
  95. a de-facto standard. To achieve this, non-free programs must be
  96. allowed to use the library. A more frequent case is that a free
  97. library does the same job as widely used non-free libraries. In this
  98. case, there is little to gain by limiting the free library to free
  99. software only, so we use the Lesser General Public License.
  100. In other cases, permission to use a particular library in non-free
  101. programs enables a greater number of people to use a large body of
  102. free software. For example, permission to use the GNU C Library in
  103. non-free programs enables many more people to use the whole GNU
  104. operating system, as well as its variant, the GNU/Linux operating
  105. system.
  106. Although the Lesser General Public License is Less protective of the
  107. users' freedom, it does ensure that the user of a program that is
  108. linked with the Library has the freedom and the wherewithal to run
  109. that program using a modified version of the Library.
  110. The precise terms and conditions for copying, distribution and
  111. modification follow. Pay close attention to the difference between a
  112. "work based on the library" and a "work that uses the library". The
  113. former contains code derived from the library, whereas the latter must
  114. be combined with the library in order to run.
  115. GNU LESSER GENERAL PUBLIC LICENSE
  116. TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
  117. 0. This License Agreement applies to any software library or other
  118. program which contains a notice placed by the copyright holder or
  119. other authorized party saying it may be distributed under the terms of
  120. this Lesser General Public License (also called "this License").
  121. Each licensee is addressed as "you".
  122. A "library" means a collection of software functions and/or data
  123. prepared so as to be conveniently linked with application programs
  124. (which use some of those functions and data) to form executables.
  125. The "Library", below, refers to any such software library or work
  126. which has been distributed under these terms. A "work based on the
  127. Library" means either the Library or any derivative work under
  128. copyright law: that is to say, a work containing the Library or a
  129. portion of it, either verbatim or with modifications and/or translated
  130. straightforwardly into another language. (Hereinafter, translation is
  131. included without limitation in the term "modification".)
  132. "Source code" for a work means the preferred form of the work for
  133. making modifications to it. For a library, complete source code means
  134. all the source code for all modules it contains, plus any associated
  135. interface definition files, plus the scripts used to control compilation
  136. and installation of the library.
  137. Activities other than copying, distribution and modification are not
  138. covered by this License; they are outside its scope. The act of
  139. running a program using the Library is not restricted, and output from
  140. such a program is covered only if its contents constitute a work based
  141. on the Library (independent of the use of the Library in a tool for
  142. writing it). Whether that is true depends on what the Library does
  143. and what the program that uses the Library does.
  144. 1. You may copy and distribute verbatim copies of the Library's
  145. complete source code as you receive it, in any medium, provided that
  146. you conspicuously and appropriately publish on each copy an
  147. appropriate copyright notice and disclaimer of warranty; keep intact
  148. all the notices that refer to this License and to the absence of any
  149. warranty; and distribute a copy of this License along with the
  150. Library.
  151. You may charge a fee for the physical act of transferring a copy,
  152. and you may at your option offer warranty protection in exchange for a
  153. fee.
  154. 2. You may modify your copy or copies of the Library or any portion
  155. of it, thus forming a work based on the Library, and copy and
  156. distribute such modifications or work under the terms of Section 1
  157. above, provided that you also meet all of these conditions:
  158. a) The modified work must itself be a software library.
  159. b) You must cause the files modified to carry prominent notices
  160. stating that you changed the files and the date of any change.
  161. c) You must cause the whole of the work to be licensed at no
  162. charge to all third parties under the terms of this License.
  163. d) If a facility in the modified Library refers to a function or a
  164. table of data to be supplied by an application program that uses
  165. the facility, other than as an argument passed when the facility
  166. is invoked, then you must make a good faith effort to ensure that,
  167. in the event an application does not supply such function or
  168. table, the facility still operates, and performs whatever part of
  169. its purpose remains meaningful.
  170. (For example, a function in a library to compute square roots has
  171. a purpose that is entirely well-defined independent of the
  172. application. Therefore, Subsection 2d requires that any
  173. application-supplied function or table used by this function must
  174. be optional: if the application does not supply it, the square
  175. root function must still compute square roots.)
  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. 3. You may opt to apply the terms of the ordinary GNU General Public
  195. License instead of this License to a given copy of the Library. To do
  196. this, you must alter all the notices that refer to this License, so
  197. that they refer to the ordinary GNU General Public License, version 2,
  198. instead of to this License. (If a newer version than version 2 of the
  199. ordinary GNU General Public License has appeared, then you can specify
  200. that version instead if you wish.) Do not make any other change in
  201. these notices.
  202. Once this change is made in a given copy, it is irreversible for
  203. that copy, so the ordinary GNU General Public License applies to all
  204. subsequent copies and derivative works made from that copy.
  205. This option is useful when you wish to copy part of the code of
  206. the Library into a program that is not a library.
  207. 4. You may copy and distribute the Library (or a portion or
  208. derivative of it, under Section 2) in object code or executable form
  209. under the terms of Sections 1 and 2 above provided that you accompany
  210. it with the complete corresponding machine-readable source code, which
  211. must be distributed under the terms of Sections 1 and 2 above on a
  212. medium customarily used for software interchange.
  213. If distribution of object code is made by offering access to copy
  214. from a designated place, then offering equivalent access to copy the
  215. source code from the same place satisfies the requirement to
  216. distribute the source code, even though third parties are not
  217. compelled to copy the source along with the object code.
  218. 5. A program that contains no derivative of any portion of the
  219. Library, but is designed to work with the Library by being compiled or
  220. linked with it, is called a "work that uses the Library". Such a
  221. work, in isolation, is not a derivative work of the Library, and
  222. therefore falls outside the scope of this License.
  223. However, linking a "work that uses the Library" with the Library
  224. creates an executable that is a derivative of the Library (because it
  225. contains portions of the Library), rather than a "work that uses the
  226. library". The executable is therefore covered by this License.
  227. Section 6 states terms for distribution of such executables.
  228. When a "work that uses the Library" uses material from a header file
  229. that is part of the Library, the object code for the work may be a
  230. derivative work of the Library even though the source code is not.
  231. Whether this is true is especially significant if the work can be
  232. linked without the Library, or if the work is itself a library. The
  233. threshold for this to be true is not precisely defined by law.
  234. If such an object file uses only numerical parameters, data
  235. structure layouts and accessors, and small macros and small inline
  236. functions (ten lines or less in length), then the use of the object
  237. file is unrestricted, regardless of whether it is legally a derivative
  238. work. (Executables containing this object code plus portions of the
  239. Library will still fall under Section 6.)
  240. Otherwise, if the work is a derivative of the Library, you may
  241. distribute the object code for the work under the terms of Section 6.
  242. Any executables containing that work also fall under Section 6,
  243. whether or not they are linked directly with the Library itself.
  244. 6. As an exception to the Sections above, you may also combine or
  245. link a "work that uses the Library" with the Library to produce a
  246. work containing portions of the Library, and distribute that work
  247. under terms of your choice, provided that the terms permit
  248. modification of the work for the customer's own use and reverse
  249. engineering for debugging such modifications.
  250. You must give prominent notice with each copy of the work that the
  251. Library is used in it and that the Library and its use are covered by
  252. this License. You must supply a copy of this License. If the work
  253. during execution displays copyright notices, you must include the
  254. copyright notice for the Library among them, as well as a reference
  255. directing the user to the copy of this License. Also, you must do one
  256. of these things:
  257. a) Accompany the work with the complete corresponding
  258. machine-readable source code for the Library including whatever
  259. changes were used in the work (which must be distributed under
  260. Sections 1 and 2 above); and, if the work is an executable linked
  261. with the Library, with the complete machine-readable "work that
  262. uses the Library", as object code and/or source code, so that the
  263. user can modify the Library and then relink to produce a modified
  264. executable containing the modified Library. (It is understood
  265. that the user who changes the contents of definitions files in the
  266. Library will not necessarily be able to recompile the application
  267. to use the modified definitions.)
  268. b) Use a suitable shared library mechanism for linking with the
  269. Library. A suitable mechanism is one that (1) uses at run time a
  270. copy of the library already present on the user's computer system,
  271. rather than copying library functions into the executable, and (2)
  272. will operate properly with a modified version of the library, if
  273. the user installs one, as long as the modified version is
  274. interface-compatible with the version that the work was made with.
  275. c) Accompany the work with a written offer, valid for at
  276. least three years, to give the same user the materials
  277. specified in Subsection 6a, above, for a charge no more
  278. than the cost of performing this distribution.
  279. d) If distribution of the work is made by offering access to copy
  280. from a designated place, offer equivalent access to copy the above
  281. specified materials from the same place.
  282. e) Verify that the user has already received a copy of these
  283. materials or that you have already sent this user a copy.
  284. For an executable, the required form of the "work that uses the
  285. Library" must include any data and utility programs needed for
  286. reproducing the executable from it. However, as a special exception,
  287. the materials to be distributed need not include anything that is
  288. normally distributed (in either source or binary form) with the major
  289. components (compiler, kernel, and so on) of the operating system on
  290. which the executable runs, unless that component itself accompanies
  291. the executable.
  292. It may happen that this requirement contradicts the license
  293. restrictions of other proprietary libraries that do not normally
  294. accompany the operating system. Such a contradiction means you cannot
  295. use both them and the Library together in an executable that you
  296. distribute.
  297. 7. You may place library facilities that are a work based on the
  298. Library side-by-side in a single library together with other library
  299. facilities not covered by this License, and distribute such a combined
  300. library, provided that the separate distribution of the work based on
  301. the Library and of the other library facilities is otherwise
  302. permitted, and provided that you do these two things:
  303. a) Accompany the combined library with a copy of the same work
  304. based on the Library, uncombined with any other library
  305. facilities. This must be distributed under the terms of the
  306. Sections above.
  307. b) Give prominent notice with the combined library of the fact
  308. that part of it is a work based on the Library, and explaining
  309. where to find the accompanying uncombined form of the same work.
  310. 8. You may not copy, modify, sublicense, link with, or distribute
  311. the Library except as expressly provided under this License. Any
  312. attempt otherwise to copy, modify, sublicense, link with, or
  313. distribute the Library is void, and will automatically terminate your
  314. rights under this License. However, parties who have received copies,
  315. or rights, from you under this License will not have their licenses
  316. terminated so long as such parties remain in full compliance.
  317. 9. You are not required to accept this License, since you have not
  318. signed it. However, nothing else grants you permission to modify or
  319. distribute the Library or its derivative works. These actions are
  320. prohibited by law if you do not accept this License. Therefore, by
  321. modifying or distributing the Library (or any work based on the
  322. Library), you indicate your acceptance of this License to do so, and
  323. all its terms and conditions for copying, distributing or modifying
  324. the Library or works based on it.
  325. 10. Each time you redistribute the Library (or any work based on the
  326. Library), the recipient automatically receives a license from the
  327. original licensor to copy, distribute, link with or modify the Library
  328. subject to these terms and conditions. You may not impose any further
  329. restrictions on the recipients' exercise of the rights granted herein.
  330. You are not responsible for enforcing compliance by third parties with
  331. this License.
  332. 11. If, as a consequence of a court judgment or allegation of patent
  333. infringement or for any other reason (not limited to patent issues),
  334. conditions are imposed on you (whether by court order, agreement or
  335. otherwise) that contradict the conditions of this License, they do not
  336. excuse you from the conditions of this License. If you cannot
  337. distribute so as to satisfy simultaneously your obligations under this
  338. License and any other pertinent obligations, then as a consequence you
  339. may not distribute the Library at all. For example, if a patent
  340. license would not permit royalty-free redistribution of the Library by
  341. all those who receive copies directly or indirectly through you, then
  342. the only way you could satisfy both it and this License would be to
  343. refrain entirely from distribution of the Library.
  344. If any portion of this section is held invalid or unenforceable under any
  345. particular circumstance, the balance of the section is intended to apply,
  346. and the section as a whole is intended to apply in other circumstances.
  347. It is not the purpose of this section to induce you to infringe any
  348. patents or other property right claims or to contest validity of any
  349. such claims; this section has the sole purpose of protecting the
  350. integrity of the free software distribution system which is
  351. implemented by public license practices. Many people have made
  352. generous contributions to the wide range of software distributed
  353. through that system in reliance on consistent application of that
  354. system; it is up to the author/donor to decide if he or she is willing
  355. to distribute software through any other system and a licensee cannot
  356. impose that choice.
  357. This section is intended to make thoroughly clear what is believed to
  358. be a consequence of the rest of this License.
  359. 12. If the distribution and/or use of the Library is restricted in
  360. certain countries either by patents or by copyrighted interfaces, the
  361. original copyright holder who places the Library under this License may add
  362. an explicit geographical distribution limitation excluding those countries,
  363. so that distribution is permitted only in or among countries not thus
  364. excluded. In such case, this License incorporates the limitation as if
  365. written in the body of this License.
  366. 13. The Free Software Foundation may publish revised and/or new
  367. versions of the Lesser General Public License from time to time.
  368. Such new versions will be similar in spirit to the present version,
  369. but may differ in detail to address new problems or concerns.
  370. Each version is given a distinguishing version number. If the Library
  371. specifies a version number of this License which applies to it and
  372. "any later version", you have the option of following the terms and
  373. conditions either of that version or of any later version published by
  374. the Free Software Foundation. If the Library does not specify a
  375. license version number, you may choose any version ever published by
  376. the Free Software Foundation.
  377. 14. If you wish to incorporate parts of the Library into other free
  378. programs whose distribution conditions are incompatible with these,
  379. write to the author to ask for permission. For software which is
  380. copyrighted by the Free Software Foundation, write to the Free
  381. Software Foundation; we sometimes make exceptions for this. Our
  382. decision will be guided by the two goals of preserving the free status
  383. of all derivatives of our free software and of promoting the sharing
  384. and reuse of software generally.
  385. NO WARRANTY
  386. 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
  387. WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
  388. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
  389. OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
  390. KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
  391. IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
  392. PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
  393. LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
  394. THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
  395. 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
  396. WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
  397. AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
  398. FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
  399. CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
  400. LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
  401. RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
  402. FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
  403. SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
  404. DAMAGES.

  409. GNU GENERAL PUBLIC LICENSE
  410. Version 2, June 1991
  411. Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
  412. 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
  413. Everyone is permitted to copy and distribute verbatim copies
  414. of this license document, but changing it is not allowed.
  415. Preamble
  416. The licenses for most software are designed to take away your
  417. freedom to share and change it. By contrast, the GNU General Public
  418. License is intended to guarantee your freedom to share and change free
  419. software--to make sure the software is free for all its users. This
  420. General Public License applies to most of the Free Software
  421. Foundation's software and to any other program whose authors commit to
  422. using it. (Some other Free Software Foundation software is covered by
  423. the GNU Lesser General Public License instead.) You can apply it to
  424. your programs, too.
  425. When we speak of free software, we are referring to freedom, not
  426. price. Our General Public Licenses are designed to make sure that you
  427. have the freedom to distribute copies of free software (and charge for
  428. this service if you wish), that you receive source code or can get it
  429. if you want it, that you can change the software or use pieces of it
  430. in new free programs; and that you know you can do these things.
  431. To protect your rights, we need to make restrictions that forbid
  432. anyone to deny you these rights or to ask you to surrender the rights.
  433. These restrictions translate to certain responsibilities for you if you
  434. distribute copies of the software, or if you modify it.
  435. For example, if you distribute copies of such a program, whether
  436. gratis or for a fee, you must give the recipients all the rights that
  437. you have. You must make sure that they, too, receive or can get the
  438. source code. And you must show them these terms so they know their
  439. rights.
  440. We protect your rights with two steps: (1) copyright the software, and
  441. (2) offer you this license which gives you legal permission to copy,
  442. distribute and/or modify the software.
  443. Also, for each author's protection and ours, we want to make certain
  444. that everyone understands that there is no warranty for this free
  445. software. If the software is modified by someone else and passed on, we
  446. want its recipients to know that what they have is not the original, so
  447. that any problems introduced by others will not reflect on the original
  448. authors' reputations.
  449. Finally, any free program is threatened constantly by software
  450. patents. We wish to avoid the danger that redistributors of a free
  451. program will individually obtain patent licenses, in effect making the
  452. program proprietary. To prevent this, we have made it clear that any
  453. patent must be licensed for everyone's free use or not licensed at all.
  454. The precise terms and conditions for copying, distribution and
  455. modification follow.
  456. GNU GENERAL PUBLIC LICENSE
  457. TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
  458. 0. This License applies to any program or other work which contains
  459. a notice placed by the copyright holder saying it may be distributed
  460. under the terms of this General Public License. The "Program", below,
  461. refers to any such program or work, and a "work based on the Program"
  462. means either the Program or any derivative work under copyright law:
  463. that is to say, a work containing the Program or a portion of it,
  464. either verbatim or with modifications and/or translated into another
  465. language. (Hereinafter, translation is included without limitation in
  466. the term "modification".) Each licensee is addressed as "you".
  467. Activities other than copying, distribution and modification are not
  468. covered by this License; they are outside its scope. The act of
  469. running the Program is not restricted, and the output from the Program
  470. is covered only if its contents constitute a work based on the
  471. Program (independent of having been made by running the Program).
  472. Whether that is true depends on what the Program does.
  473. 1. You may copy and distribute verbatim copies of the Program's
  474. source code as you receive it, in any medium, provided that you
  475. conspicuously and appropriately publish on each copy an appropriate
  476. copyright notice and disclaimer of warranty; keep intact all the
  477. notices that refer to this License and to the absence of any warranty;
  478. and give any other recipients of the Program a copy of this License
  479. along with the Program.
  480. You may charge a fee for the physical act of transferring a copy, and
  481. you may at your option offer warranty protection in exchange for a fee.
  482. 2. You may modify your copy or copies of the Program or any portion
  483. of it, thus forming a work based on the Program, and copy and
  484. distribute such modifications or work under the terms of Section 1
  485. above, provided that you also meet all of these conditions:
  486. a) You must cause the modified files to carry prominent notices
  487. stating that you changed the files and the date of any change.
  488. b) You must cause any work that you distribute or publish, that in
  489. whole or in part contains or is derived from the Program or any
  490. part thereof, to be licensed as a whole at no charge to all third
  491. parties under the terms of this License.
  492. c) If the modified program normally reads commands interactively
  493. when run, you must cause it, when started running for such
  494. interactive use in the most ordinary way, to print or display an
  495. announcement including an appropriate copyright notice and a
  496. notice that there is no warranty (or else, saying that you provide
  497. a warranty) and that users may redistribute the program under
  498. these conditions, and telling the user how to view a copy of this
  499. License. (Exception: if the Program itself is interactive but
  500. does not normally print such an announcement, your work based on
  501. the Program is not required to print an announcement.)
  502. These requirements apply to the modified work as a whole. If
  503. identifiable sections of that work are not derived from the Program,
  504. and can be reasonably considered independent and separate works in
  505. themselves, then this License, and its terms, do not apply to those
  506. sections when you distribute them as separate works. But when you
  507. distribute the same sections as part of a whole which is a work based
  508. on the Program, the distribution of the whole must be on the terms of
  509. this License, whose permissions for other licensees extend to the
  510. entire whole, and thus to each and every part regardless of who wrote it.
  511. Thus, it is not the intent of this section to claim rights or contest
  512. your rights to work written entirely by you; rather, the intent is to
  513. exercise the right to control the distribution of derivative or
  514. collective works based on the Program.
  515. In addition, mere aggregation of another work not based on the Program
  516. with the Program (or with a work based on the Program) on a volume of
  517. a storage or distribution medium does not bring the other work under
  518. the scope of this License.
  519. 3. You may copy and distribute the Program (or a work based on it,
  520. under Section 2) in object code or executable form under the terms of
  521. Sections 1 and 2 above provided that you also do one of the following:
  522. a) Accompany it with the complete corresponding machine-readable
  523. source code, which must be distributed under the terms of Sections
  524. 1 and 2 above on a medium customarily used for software interchange; or,
  525. b) Accompany it with a written offer, valid for at least three
  526. years, to give any third party, for a charge no more than your
  527. cost of physically performing source distribution, a complete
  528. machine-readable copy of the corresponding source code, to be
  529. distributed under the terms of Sections 1 and 2 above on a medium
  530. customarily used for software interchange; or,
  531. c) Accompany it with the information you received as to the offer
  532. to distribute corresponding source code. (This alternative is
  533. allowed only for noncommercial distribution and only if you
  534. received the program in object code or executable form with such
  535. an offer, in accord with Subsection b above.)
  536. The source code for a work means the preferred form of the work for
  537. making modifications to it. For an executable work, complete source
  538. code means all the source code for all modules it contains, plus any
  539. associated interface definition files, plus the scripts used to
  540. control compilation and installation of the executable. However, as a
  541. special exception, the source code distributed need not include
  542. anything that is normally distributed (in either source or binary
  543. form) with the major components (compiler, kernel, and so on) of the
  544. operating system on which the executable runs, unless that component
  545. itself accompanies the executable.
  546. If distribution of executable or object code is made by offering
  547. access to copy from a designated place, then offering equivalent
  548. access to copy the source code from the same place counts as
  549. distribution of the source code, even though third parties are not
  550. compelled to copy the source along with the object code.
  551. 4. You may not copy, modify, sublicense, or distribute the Program
  552. except as expressly provided under this License. Any attempt
  553. otherwise to copy, modify, sublicense or distribute the Program is
  554. void, and will automatically terminate your rights under this License.
  555. However, parties who have received copies, or rights, from you under
  556. this License will not have their licenses terminated so long as such
  557. parties remain in full compliance.
  558. 5. You are not required to accept this License, since you have not
  559. signed it. However, nothing else grants you permission to modify or
  560. distribute the Program or its derivative works. These actions are
  561. prohibited by law if you do not accept this License. Therefore, by
  562. modifying or distributing the Program (or any work based on the
  563. Program), you indicate your acceptance of this License to do so, and
  564. all its terms and conditions for copying, distributing or modifying
  565. the Program or works based on it.
  566. 6. Each time you redistribute the Program (or any work based on the
  567. Program), the recipient automatically receives a license from the
  568. original licensor to copy, distribute or modify the Program subject to
  569. these terms and conditions. You may not impose any further
  570. restrictions on the recipients' exercise of the rights granted herein.
  571. You are not responsible for enforcing compliance by third parties to
  572. this License.
  573. 7. If, as a consequence of a court judgment or allegation of patent
  574. infringement or for any other reason (not limited to patent issues),
  575. conditions are imposed on you (whether by court order, agreement or
  576. otherwise) that contradict the conditions of this License, they do not
  577. excuse you from the conditions of this License. If you cannot
  578. distribute so as to satisfy simultaneously your obligations under this
  579. License and any other pertinent obligations, then as a consequence you
  580. may not distribute the Program at all. For example, if a patent
  581. license would not permit royalty-free redistribution of the Program by
  582. all those who receive copies directly or indirectly through you, then
  583. the only way you could satisfy both it and this License would be to
  584. refrain entirely from distribution of the Program.
  585. If any portion of this section is held invalid or unenforceable under
  586. any particular circumstance, the balance of the section is intended to
  587. apply and the section as a whole is intended to apply in other
  588. circumstances.
  589. It is not the purpose of this section to induce you to infringe any
  590. patents or other property right claims or to contest validity of any
  591. such claims; this section has the sole purpose of protecting the
  592. integrity of the free software distribution system, which is
  593. implemented by public license practices. Many people have made
  594. generous contributions to the wide range of software distributed
  595. through that system in reliance on consistent application of that
  596. system; it is up to the author/donor to decide if he or she is willing
  597. to distribute software through any other system and a licensee cannot
  598. impose that choice.
  599. This section is intended to make thoroughly clear what is believed to
  600. be a consequence of the rest of this License.
  601. 8. If the distribution and/or use of the Program is restricted in
  602. certain countries either by patents or by copyrighted interfaces, the
  603. original copyright holder who places the Program under this License
  604. may add an explicit geographical distribution limitation excluding
  605. those countries, so that distribution is permitted only in or among
  606. countries not thus excluded. In such case, this License incorporates
  607. the limitation as if written in the body of this License.
  608. 9. The Free Software Foundation may publish revised and/or new versions
  609. of the General Public License from time to time. Such new versions will
  610. be similar in spirit to the present version, but may differ in detail to
  611. address new problems or concerns.
  612. Each version is given a distinguishing version number. If the Program
  613. specifies a version number of this License which applies to it and "any
  614. later version", you have the option of following the terms and conditions
  615. either of that version or of any later version published by the Free
  616. Software Foundation. If the Program does not specify a version number of
  617. this License, you may choose any version ever published by the Free Software
  618. Foundation.
  619. 10. If you wish to incorporate parts of the Program into other free
  620. programs whose distribution conditions are different, write to the author
  621. to ask for permission. For software which is copyrighted by the Free
  622. Software Foundation, write to the Free Software Foundation; we sometimes
  623. make exceptions for this. Our decision will be guided by the two goals
  624. of preserving the free status of all derivatives of our free software and
  625. of promoting the sharing and reuse of software generally.
  626. NO WARRANTY
  627. 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
  628. FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
  629. OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
  630. PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
  631. OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
  632. MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
  633. TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
  634. PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
  635. REPAIR OR CORRECTION.
  636. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
  637. WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
  638. REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
  639. INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
  640. OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
  641. TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
  642. YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
  643. PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
  644. POSSIBILITY OF SUCH DAMAGES.
  645. END OF TERMS AND CONDITIONS
