  165. LICENSE</a></h3>
  166. <p>
  167. Version 2, June 1991
  168. </p>
  169. <pre>
  170. Copyright (C) 1991 Free Software Foundation, Inc.
  171. 51 Franklin St, Fifth Floor, Boston, MA 02110-1301, USA
  172. Everyone is permitted to copy and distribute verbatim copies
  173. of this license document, but changing it is not allowed.
  174. [This is the first released version of the library GPL. It is
  175. numbered 2 because it goes with version 2 of the ordinary GPL.]
  176. </pre>
  177. <h3><a id="SEC2">Preamble</a></h3>
  178. <p>
  179. The licenses for most software are designed to take away your
  180. freedom to share and change it. By contrast, the GNU General Public
  181. Licenses are intended to guarantee your freedom to share and change
  182. free software--to make sure the software is free for all its users.
  183. </p>
  184. <p>
  185. This license, the Library General Public License, applies to some
  186. specially designated Free Software Foundation software, and to any
  187. other libraries whose authors decide to use it. You can use it for
  188. your libraries, too.
  189. </p>
  190. <p>
  191. When we speak of free software, we are referring to freedom, not
  192. price. Our General Public Licenses are designed to make sure that you
  193. have the freedom to distribute copies of free software (and charge for
  194. this service if you wish), that you receive source code or can get it
  195. if you want it, that you can change the software or use pieces of it
  196. in new free programs; and that you know you can do these things.
  197. </p>
  198. <p>
  199. To protect your rights, we need to make restrictions that forbid
  200. anyone to deny you these rights or to ask you to surrender the rights.
  201. These restrictions translate to certain responsibilities for you if
  202. you distribute copies of the library, or if you modify it.
  203. </p>
  204. <p>
  205. For example, if you distribute copies of the library, whether gratis
  206. or for a fee, you must give the recipients all the rights that we gave
  207. you. You must make sure that they, too, receive or can get the source
  208. code. If you link a program with the library, you must provide
  209. complete object files to the recipients so that they can relink them
  210. with the library, after making changes to the library and recompiling
  211. it. And you must show them these terms so they know their rights.
  212. </p>
  213. <p>
  214. Our method of protecting your rights has two steps: (1) copyright
  215. the library, and (2) offer you this license which gives you legal
  216. permission to copy, distribute and/or modify the library.
  217. </p>
  218. <p>
  219. Also, for each distributor's protection, we want to make certain
  220. that everyone understands that there is no warranty for this free
  221. library. If the library is modified by someone else and passed on, we
  222. want its recipients to know that what they have is not the original
  223. version, so that any problems introduced by others will not reflect on
  224. the original authors' reputations.
  225. </p>
  226. <p>
  227. Finally, any free program is threatened constantly by software
  228. patents. We wish to avoid the danger that companies distributing free
  229. software will individually obtain patent licenses, thus in effect
  230. transforming the program into proprietary software. To prevent this,
  231. we have made it clear that any patent must be licensed for everyone's
  232. free use or not licensed at all.
  233. </p>
  234. <p>
  235. Most GNU software, including some libraries, is covered by the ordinary
  236. GNU General Public License, which was designed for utility programs. This
  237. license, the GNU Library General Public License, applies to certain
  238. designated libraries. This license is quite different from the ordinary
  239. one; be sure to read it in full, and don't assume that anything in it is
  240. the same as in the ordinary license.
  241. </p>
  242. <p>
  243. The reason we have a separate public license for some libraries is that
  244. they blur the distinction we usually make between modifying or adding to a
  245. program and simply using it. Linking a program with a library, without
  246. changing the library, is in some sense simply using the library, and is
  247. analogous to running a utility program or application program. However, in
  248. a textual and legal sense, the linked executable is a combined work, a
  249. derivative of the original library, and the ordinary General Public License
  250. treats it as such.
  251. </p>
  252. <p>
  253. Because of this blurred distinction, using the ordinary General
  254. Public License for libraries did not effectively promote software
  255. sharing, because most developers did not use the libraries. We
  256. concluded that weaker conditions might promote sharing better.
  257. </p>
  258. <p>
  259. However, unrestricted linking of non-free programs would deprive the
  260. users of those programs of all benefit from the free status of the
  261. libraries themselves. This Library General Public License is intended to
  262. permit developers of non-free programs to use free libraries, while
  263. preserving your freedom as a user of such programs to change the free
  264. libraries that are incorporated in them. (We have not seen how to achieve
  265. this as regards changes in header files, but we have achieved it as regards
  266. changes in the actual functions of the Library.) The hope is that this
  267. will lead to faster development of free libraries.
  268. </p>
  269. <p>
  270. The precise terms and conditions for copying, distribution and
  271. modification follow. Pay close attention to the difference between a
  272. "work based on the library" and a "work that uses the library". The
  273. former contains code derived from the library, while the latter only
  274. works together with the library.
  275. </p>
  276. <p>
  277. Note that it is possible for a library to be covered by the ordinary
  278. General Public License rather than by this special one.
  279. </p>
  280. <h3><a id="SEC3">TERMS AND CONDITIONS FOR
  281. COPYING, DISTRIBUTION AND MODIFICATION</a></h3>
  282. <p>
  283. <strong>0.</strong>
  284. This License Agreement applies to any software library which
  285. contains a notice placed by the copyright holder or other authorized
  286. party saying it may be distributed under the terms of this Library
  287. General Public License (also called "this License"). Each licensee is
  288. addressed as "you".
  289. </p>
  290. <p>
  291. A "library" means a collection of software functions and/or data
  292. prepared so as to be conveniently linked with application programs
  293. (which use some of those functions and data) to form executables.
  294. </p>
  295. <p>
  296. The "Library", below, refers to any such software library or work
  297. which has been distributed under these terms. A "work based on the
  298. Library" means either the Library or any derivative work under
  299. copyright law: that is to say, a work containing the Library or a
  300. portion of it, either verbatim or with modifications and/or translated
  301. straightforwardly into another language. (Hereinafter, translation is
  302. included without limitation in the term "modification".)
  303. </p>
  304. <p>
  305. "Source code" for a work means the preferred form of the work for
  306. making modifications to it. For a library, complete source code means
  307. all the source code for all modules it contains, plus any associated
  308. interface definition files, plus the scripts used to control compilation
  309. and installation of the library.
  310. </p>
  311. <p>
  312. Activities other than copying, distribution and modification are not
  313. covered by this License; they are outside its scope. The act of
  314. running a program using the Library is not restricted, and output from
  315. such a program is covered only if its contents constitute a work based
  316. on the Library (independent of the use of the Library in a tool for
  317. writing it). Whether that is true depends on what the Library does
  318. and what the program that uses the Library does.
  319. </p>
  320. <p>
  321. <strong>1.</strong>
  322. You may copy and distribute verbatim copies of the Library's
  323. complete source code as you receive it, in any medium, provided that
  324. you conspicuously and appropriately publish on each copy an
  325. appropriate copyright notice and disclaimer of warranty; keep intact
  326. all the notices that refer to this License and to the absence of any
  327. warranty; and distribute a copy of this License along with the
  328. Library.
  329. </p>
  330. <p>
  331. You may charge a fee for the physical act of transferring a copy,
  332. and you may at your option offer warranty protection in exchange for a
  333. fee.
  334. </p>
  335. <p>
  336. <strong>2.</strong>
  337. You may modify your copy or copies of the Library or any portion
  338. of it, thus forming a work based on the Library, and copy and
  339. distribute such modifications or work under the terms of Section 1
  340. above, provided that you also meet all of these conditions:
  341. </p>
  342. <!-- we use this doubled UL to get the sub-sections indented, -->
  343. <!-- while making the bullets as unobvious as possible. -->
  344. <ul>
  345. <li><strong>a)</strong>
  346. The modified work must itself be a software library.
  347. </li>
  348. <li><strong>b)</strong>
  349. You must cause the files modified to carry prominent notices
  350. stating that you changed the files and the date of any change.
  351. </li>
  352. <li><strong>c)</strong>
  353. You must cause the whole of the work to be licensed at no
  354. charge to all third parties under the terms of this License.
  355. </li>
  356. <li><strong>d)</strong>
  357. If a facility in the modified Library refers to a function or a
  358. table of data to be supplied by an application program that uses
  359. the facility, other than as an argument passed when the facility
  360. is invoked, then you must make a good faith effort to ensure that,
  361. in the event an application does not supply such function or
  362. table, the facility still operates, and performs whatever part of
  363. its purpose remains meaningful.
  364. <p>
  365. (For example, a function in a library to compute square roots has
  366. a purpose that is entirely well-defined independent of the
  367. application. Therefore, Subsection 2d requires that any
  368. application-supplied function or table used by this function must
  369. be optional: if the application does not supply it, the square
  370. root function must still compute square roots.)</p>
  371. </li>
  372. </ul>
  373. <p>
  374. These requirements apply to the modified work as a whole. If
  375. identifiable sections of that work are not derived from the Library,
  376. and can be reasonably considered independent and separate works in
  377. themselves, then this License, and its terms, do not apply to those
  378. sections when you distribute them as separate works. But when you
  379. distribute the same sections as part of a whole which is a work based
  380. on the Library, the distribution of the whole must be on the terms of
  381. this License, whose permissions for other licensees extend to the
  382. entire whole, and thus to each and every part regardless of who wrote
  383. it.
  384. </p>
  385. <p>
  386. Thus, it is not the intent of this section to claim rights or contest
  387. your rights to work written entirely by you; rather, the intent is to
  388. exercise the right to control the distribution of derivative or
  389. collective works based on the Library.
  390. </p>
  391. <p>
  392. In addition, mere aggregation of another work not based on the Library
  393. with the Library (or with a work based on the Library) on a volume of
  394. a storage or distribution medium does not bring the other work under
  395. the scope of this License.
  396. </p>
  397. <p>
  398. <strong>3.</strong>
  399. You may opt to apply the terms of the ordinary GNU General Public
  400. License instead of this License to a given copy of the Library. To do
  401. this, you must alter all the notices that refer to this License, so
  402. that they refer to the ordinary GNU General Public License, version 2,
  403. instead of to this License. (If a newer version than version 2 of the
  404. ordinary GNU General Public License has appeared, then you can specify
  405. that version instead if you wish.) Do not make any other change in
  406. these notices.
  407. </p>
  408. <p>
  409. Once this change is made in a given copy, it is irreversible for
  410. that copy, so the ordinary GNU General Public License applies to all
  411. subsequent copies and derivative works made from that copy.
  412. </p>
  413. <p>
  414. This option is useful when you wish to copy part of the code of
  415. the Library into a program that is not a library.
  416. </p>
  417. <p>
  418. <strong>4.</strong>
  419. You may copy and distribute the Library (or a portion or
  420. derivative of it, under Section 2) in object code or executable form
  421. under the terms of Sections 1 and 2 above provided that you accompany
  422. it with the complete corresponding machine-readable source code, which
  423. must be distributed under the terms of Sections 1 and 2 above on a
  424. medium customarily used for software interchange.
  425. </p>
  426. <p>
  427. If distribution of object code is made by offering access to copy
  428. from a designated place, then offering equivalent access to copy the
  429. source code from the same place satisfies the requirement to
  430. distribute the source code, even though third parties are not
  431. compelled to copy the source along with the object code.
  432. </p>
  433. <p>
  434. <strong>5.</strong>
  435. A program that contains no derivative of any portion of the
  436. Library, but is designed to work with the Library by being compiled or
  437. linked with it, is called a "work that uses the Library". Such a
  438. work, in isolation, is not a derivative work of the Library, and
  439. therefore falls outside the scope of this License.
  440. </p>
  441. <p>
  442. However, linking a "work that uses the Library" with the Library
  443. creates an executable that is a derivative of the Library (because it
  444. contains portions of the Library), rather than a "work that uses the
  445. library". The executable is therefore covered by this License.
  446. Section 6 states terms for distribution of such executables.
  447. </p>
  448. <p>
  449. When a "work that uses the Library" uses material from a header file
  450. that is part of the Library, the object code for the work may be a
  451. derivative work of the Library even though the source code is not.
  452. Whether this is true is especially significant if the work can be
  453. linked without the Library, or if the work is itself a library. The
  454. threshold for this to be true is not precisely defined by law.
  455. </p>
  456. <p>
  457. If such an object file uses only numerical parameters, data
  458. structure layouts and accessors, and small macros and small inline
  459. functions (ten lines or less in length), then the use of the object
  460. file is unrestricted, regardless of whether it is legally a derivative
  461. work. (Executables containing this object code plus portions of the
  462. Library will still fall under Section 6.)
  463. </p>
  464. <p>
  465. Otherwise, if the work is a derivative of the Library, you may
  466. distribute the object code for the work under the terms of Section 6.
  467. Any executables containing that work also fall under Section 6,
  468. whether or not they are linked directly with the Library itself.
  469. </p>
  470. <p>
  471. <strong>6.</strong>
  472. As an exception to the Sections above, you may also compile or
  473. link a "work that uses the Library" with the Library to produce a
  474. work containing portions of the Library, and distribute that work
  475. under terms of your choice, provided that the terms permit
  476. modification of the work for the customer's own use and reverse
  477. engineering for debugging such modifications.
  478. </p>
  479. <p>
  480. You must give prominent notice with each copy of the work that the
  481. Library is used in it and that the Library and its use are covered by
  482. this License. You must supply a copy of this License. If the work
  483. during execution displays copyright notices, you must include the
  484. copyright notice for the Library among them, as well as a reference
  485. directing the user to the copy of this License. Also, you must do one
  486. of these things:
  487. </p>
  488. <!-- we use this doubled UL to get the sub-sections indented, -->
  489. <!-- while making the bullets as unobvious as possible. -->
  490. <ul>
  491. <li><strong>a)</strong>
  492. Accompany the work with the complete corresponding
  493. machine-readable source code for the Library including whatever
  494. changes were used in the work (which must be distributed under
  495. Sections 1 and 2 above); and, if the work is an executable linked
  496. with the Library, with the complete machine-readable "work that
  497. uses the Library", as object code and/or source code, so that the
  498. user can modify the Library and then relink to produce a modified
  499. executable containing the modified Library. (It is understood
  500. that the user who changes the contents of definitions files in the
  501. Library will not necessarily be able to recompile the application
  502. to use the modified definitions.)
  503. </li>
  504. <li><strong>b)</strong>
  505. Accompany the work with a written offer, valid for at
  506. least three years, to give the same user the materials
  507. specified in Subsection 6a, above, for a charge no more
  508. than the cost of performing this distribution.
  509. </li>
  510. <li><strong>c)</strong>
  511. If distribution of the work is made by offering access to copy
  512. from a designated place, offer equivalent access to copy the above
  513. specified materials from the same place.
  514. </li>
  515. <li><strong>d)</strong>
  516. Verify that the user has already received a copy of these
  517. materials or that you have already sent this user a copy.
  518. </li>
  519. </ul>
  520. <p>
  521. For an executable, the required form of the "work that uses the
  522. Library" must include any data and utility programs needed for
  523. reproducing the executable from it. However, as a special exception,
  524. the source code distributed need not include anything that is normally
  525. distributed (in either source or binary form) with the major
  526. components (compiler, kernel, and so on) of the operating system on
  527. which the executable runs, unless that component itself accompanies
  528. the executable.
  529. </p>
  530. <p>
  531. It may happen that this requirement contradicts the license
  532. restrictions of other proprietary libraries that do not normally
  533. accompany the operating system. Such a contradiction means you cannot
  534. use both them and the Library together in an executable that you
  535. distribute.
  536. </p>
  537. <p>
  538. <strong>7.</strong>
  539. You may place library facilities that are a work based on the
  540. Library side-by-side in a single library together with other library
  541. facilities not covered by this License, and distribute such a combined
  542. library, provided that the separate distribution of the work based on
  543. the Library and of the other library facilities is otherwise
  544. permitted, and provided that you do these two things:
  545. </p>
  546. <!-- we use this doubled UL to get the sub-sections indented, -->
  547. <!-- while making the bullets as unobvious as possible. -->
  548. <ul>
  549. <li><strong>a)</strong>
  550. Accompany the combined library with a copy of the same work
  551. based on the Library, uncombined with any other library
  552. facilities. This must be distributed under the terms of the
  553. Sections above.
  554. </li>
  555. <li><strong>b)</strong>
  556. Give prominent notice with the combined library of the fact
  557. that part of it is a work based on the Library, and explaining
  558. where to find the accompanying uncombined form of the same work.
  559. </li>
  560. </ul>
  561. <p>
  562. <strong>8.</strong>
  563. You may not copy, modify, sublicense, link with, or distribute
  564. the Library except as expressly provided under this License. Any
  565. attempt otherwise to copy, modify, sublicense, link with, or
  566. distribute the Library is void, and will automatically terminate your
  567. rights under this License. However, parties who have received copies,
  568. or rights, from you under this License will not have their licenses
  569. terminated so long as such parties remain in full compliance.
  570. </p>
  571. <p>
  572. <strong>9.</strong>
  573. You are not required to accept this License, since you have not
  574. signed it. However, nothing else grants you permission to modify or
  575. distribute the Library or its derivative works. These actions are
  576. prohibited by law if you do not accept this License. Therefore, by
  577. modifying or distributing the Library (or any work based on the
  578. Library), you indicate your acceptance of this License to do so, and
  579. all its terms and conditions for copying, distributing or modifying
  580. the Library or works based on it.
  581. </p>
  582. <p>
  583. <strong>10.</strong>
  584. Each time you redistribute the Library (or any work based on the
  585. Library), the recipient automatically receives a license from the
  586. original licensor to copy, distribute, link with or modify the Library
  587. subject to these terms and conditions. You may not impose any further
  588. restrictions on the recipients' exercise of the rights granted herein.
  589. You are not responsible for enforcing compliance by third parties to
  590. this License.
  591. </p>
  592. <p>
  593. <strong>11.</strong>
  594. If, as a consequence of a court judgment or allegation of patent
  595. infringement or for any other reason (not limited to patent issues),
  596. conditions are imposed on you (whether by court order, agreement or
  597. otherwise) that contradict the conditions of this License, they do not
  598. excuse you from the conditions of this License. If you cannot
  599. distribute so as to satisfy simultaneously your obligations under this
  600. License and any other pertinent obligations, then as a consequence you
  601. may not distribute the Library at all. For example, if a patent
  602. license would not permit royalty-free redistribution of the Library by
  603. all those who receive copies directly or indirectly through you, then
  604. the only way you could satisfy both it and this License would be to
  605. refrain entirely from distribution of the Library.
  606. </p>
  607. <p>
  608. If any portion of this section is held invalid or unenforceable under any
  609. particular circumstance, the balance of the section is intended to apply,
  610. and the section as a whole is intended to apply in other circumstances.
  611. </p>
  612. <p>
  613. It is not the purpose of this section to induce you to infringe any
  614. patents or other property right claims or to contest validity of any
  615. such claims; this section has the sole purpose of protecting the
  616. integrity of the free software distribution system which is
  617. implemented by public license practices. Many people have made
  618. generous contributions to the wide range of software distributed
  619. through that system in reliance on consistent application of that
  620. system; it is up to the author/donor to decide if he or she is willing
  621. to distribute software through any other system and a licensee cannot
  622. impose that choice.
  623. </p>
  624. <p>
  625. This section is intended to make thoroughly clear what is believed to
  626. be a consequence of the rest of this License.
  627. </p>
  628. <p>
  629. <strong>12.</strong>
  630. If the distribution and/or use of the Library is restricted in
  631. certain countries either by patents or by copyrighted interfaces, the
  632. original copyright holder who places the Library under this License may add
  633. an explicit geographical distribution limitation excluding those countries,
  634. so that distribution is permitted only in or among countries not thus
  635. excluded. In such case, this License incorporates the limitation as if
  636. written in the body of this License.
  637. </p>
  638. <p>
  639. <strong>13.</strong>
  640. The Free Software Foundation may publish revised and/or new
  641. versions of the Library General Public License from time to time.
  642. Such new versions will be similar in spirit to the present version,
  643. but may differ in detail to address new problems or concerns.
  644. </p>
  645. <p>
  646. Each version is given a distinguishing version number. If the Library
  647. specifies a version number of this License which applies to it and
  648. "any later version", you have the option of following the terms and
  649. conditions either of that version or of any later version published by
  650. the Free Software Foundation. If the Library does not specify a
  651. license version number, you may choose any version ever published by
  652. the Free Software Foundation.
  653. </p>
  654. <p>
  655. <strong>14.</strong>
  656. If you wish to incorporate parts of the Library into other free
  657. programs whose distribution conditions are incompatible with these,
  658. write to the author to ask for permission. For software which is
  659. copyrighted by the Free Software Foundation, write to the Free
  660. Software Foundation; we sometimes make exceptions for this. Our
  661. decision will be guided by the two goals of preserving the free status
  662. of all derivatives of our free software and of promoting the sharing
  663. and reuse of software generally.
  664. </p>
  665. <p><strong>NO WARRANTY</strong></p>
  666. <p>
  667. <strong>15.</strong>
  668. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
  669. WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
  670. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
  671. OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
  672. KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
  673. IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
  674. PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
  675. LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
  676. THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
  677. </p>
  678. <p>
  679. <strong>16.</strong>
  680. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
  681. WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
  682. AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
  683. FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
  684. CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
  685. LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
  686. RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
  687. FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
  688. SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
  689. DAMAGES.
  690. </p>
  691. <h3>END OF TERMS AND CONDITIONS</h3>
  692. <h3><a id="SEC4">How to Apply These Terms
  693. to Your New Libraries</a></h3>
  694. <p>
  695. If you develop a new library, and you want it to be of the greatest
  696. possible use to the public, we recommend making it free software that
  697. everyone can redistribute and change. You can do so by permitting
  698. redistribution under these terms (or, alternatively, under the terms of the
  699. ordinary General Public License).
  700. </p>
  701. <p>
  702. To apply these terms, attach the following notices to the library. It is
  703. safest to attach them to the start of each source file to most effectively
  704. convey the exclusion of warranty; and each file should have at least the
  705. "copyright" line and a pointer to where the full notice is found.
  706. </p>

  710. This library is free software; you can redistribute it and/or
  711. modify it under the terms of the GNU Library General Public
