  10. GNU LESSER GENERAL PUBLIC LICENSE
  11. Version 3, 29 June 2007
  12. Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
  13. Everyone is permitted to copy and distribute verbatim copies
  14. of this license document, but changing it is not allowed.
  15. This version of the GNU Lesser General Public License incorporates
  16. the terms and conditions of version 3 of the GNU General Public
  17. License, supplemented by the additional permissions listed below.
  18. 0. Additional Definitions.
  19. As used herein, "this License" refers to version 3 of the GNU Lesser
  20. General Public License, and the "GNU GPL" refers to version 3 of the GNU
  21. General Public License.
  22. "The Library" refers to a covered work governed by this License,
  23. other than an Application or a Combined Work as defined below.
  24. An "Application" is any work that makes use of an interface provided
  25. by the Library, but which is not otherwise based on the Library.
  26. Defining a subclass of a class defined by the Library is deemed a mode
  27. of using an interface provided by the Library.
  28. A "Combined Work" is a work produced by combining or linking an
  29. Application with the Library. The particular version of the Library
  30. with which the Combined Work was made is also called the "Linked
  31. Version".
  32. The "Minimal Corresponding Source" for a Combined Work means the
  33. Corresponding Source for the Combined Work, excluding any source code
  34. for portions of the Combined Work that, considered in isolation, are
  35. based on the Application, and not on the Linked Version.
  36. The "Corresponding Application Code" for a Combined Work means the
  37. object code and/or source code for the Application, including any data
  38. and utility programs needed for reproducing the Combined Work from the
  39. Application, but excluding the System Libraries of the Combined Work.
  40. 1. Exception to Section 3 of the GNU GPL.
  41. You may convey a covered work under sections 3 and 4 of this License
  42. without being bound by section 3 of the GNU GPL.
  43. 2. Conveying Modified Versions.
  44. If you modify a copy of the Library, and, in your modifications, a
  45. facility refers to a function or data to be supplied by an Application
  46. that uses the facility (other than as an argument passed when the
  47. facility is invoked), then you may convey a copy of the modified
  48. version:
  49. a) under this License, provided that you make a good faith effort to
  50. ensure that, in the event an Application does not supply the
  51. function or data, the facility still operates, and performs
  52. whatever part of its purpose remains meaningful, or
  53. b) under the GNU GPL, with none of the additional permissions of
  54. this License applicable to that copy.
  55. 3. Object Code Incorporating Material from Library Header Files.
  56. The object code form of an Application may incorporate material from
  57. a header file that is part of the Library. You may convey such object
  58. code under terms of your choice, provided that, if the incorporated
  59. material is not limited to numerical parameters, data structure
  60. layouts and accessors, or small macros, inline functions and templates
  61. (ten or fewer lines in length), you do both of the following:
  62. a) Give prominent notice with each copy of the object code that the
  63. Library is used in it and that the Library and its use are
  64. covered by this License.
  65. b) Accompany the object code with a copy of the GNU GPL and this license
  66. document.
  67. 4. Combined Works.
  68. You may convey a Combined Work under terms of your choice that,
  69. taken together, effectively do not restrict modification of the
  70. portions of the Library contained in the Combined Work and reverse
  71. engineering for debugging such modifications, if you also do each of
  72. the following:
  73. a) Give prominent notice with each copy of the Combined Work that
  74. the Library is used in it and that the Library and its use are
  75. covered by this License.
  76. b) Accompany the Combined Work with a copy of the GNU GPL and this license
  77. document.
  78. c) For a Combined Work that displays copyright notices during
  79. execution, include the copyright notice for the Library among
  80. these notices, as well as a reference directing the user to the
  81. copies of the GNU GPL and this license document.
  82. d) Do one of the following:
  83. 0) Convey the Minimal Corresponding Source under the terms of this
  84. License, and the Corresponding Application Code in a form
  85. suitable for, and under terms that permit, the user to
  86. recombine or relink the Application with a modified version of
  87. the Linked Version to produce a modified Combined Work, in the
  88. manner specified by section 6 of the GNU GPL for conveying
  89. Corresponding Source.
  90. 1) Use a suitable shared library mechanism for linking with the
  91. Library. A suitable mechanism is one that (a) uses at run time
  92. a copy of the Library already present on the user's computer
  93. system, and (b) will operate properly with a modified version
  94. of the Library that is interface-compatible with the Linked
  95. Version.
  96. e) Provide Installation Information, but only if you would otherwise
  97. be required to provide such information under section 6 of the
  98. GNU GPL, and only to the extent that such information is
  99. necessary to install and execute a modified version of the
  100. Combined Work produced by recombining or relinking the
  101. Application with a modified version of the Linked Version. (If
  102. you use option 4d0, the Installation Information must accompany
  103. the Minimal Corresponding Source and Corresponding Application
  104. Code. If you use option 4d1, you must provide the Installation
  105. Information in the manner specified by section 6 of the GNU GPL
  106. for conveying Corresponding Source.)
  107. 5. Combined Libraries.
  108. You may place library facilities that are a work based on the
  109. Library side by side in a single library together with other library
  110. facilities that are not Applications and are not covered by this
  111. License, and convey such a combined library under terms of your
  112. choice, if you do both of the following:
  113. a) Accompany the combined library with a copy of the same work based
  114. on the Library, uncombined with any other library facilities,
  115. conveyed under the terms of this License.
  116. b) Give prominent notice with the combined library that part of it
  117. is a work based on the Library, and explaining where to find the
  118. accompanying uncombined form of the same work.
  119. 6. Revised Versions of the GNU Lesser General Public License.
  120. The Free Software Foundation may publish revised and/or new versions
  121. of the GNU Lesser General Public License from time to time. Such new
  122. versions will be similar in spirit to the present version, but may
  123. differ in detail to address new problems or concerns.
  124. Each version is given a distinguishing version number. If the
  125. Library as you received it specifies that a certain numbered version
  126. of the GNU Lesser General Public License "or any later version"
  127. applies to it, you have the option of following the terms and
  128. conditions either of that published version or of any later version
  129. published by the Free Software Foundation. If the Library as you
  130. received it does not specify a version number of the GNU Lesser
  131. General Public License, you may choose any version of the GNU Lesser
  132. General Public License ever published by the Free Software Foundation.
  133. If the Library as you received it specifies that a proxy can decide
  134. whether future versions of the GNU Lesser General Public License shall
  135. apply, that proxy's public statement of acceptance of any version is
  136. permanent authorization for you to choose that version for the
  137. Library.

  140. GNU GENERAL PUBLIC LICENSE
  141. Version 3, 29 June 2007
  142. Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
  143. Everyone is permitted to copy and distribute verbatim copies
  144. of this license document, but changing it is not allowed.
  145. Preamble
  146. The GNU General Public License is a free, copyleft license for
  147. software and other kinds of works.
  148. The licenses for most software and other practical works are designed
  149. to take away your freedom to share and change the works. By contrast,
  150. the GNU General Public License is intended to guarantee your freedom to
  151. share and change all versions of a program--to make sure it remains free
  152. software for all its users. We, the Free Software Foundation, use the
  153. GNU General Public License for most of our software; it applies also to
  154. any other work released this way by its authors. You can apply it to
  155. your programs, too.
  156. When we speak of free software, we are referring to freedom, not
  157. price. Our General Public Licenses are designed to make sure that you
  158. have the freedom to distribute copies of free software (and charge for
  159. them if you wish), that you receive source code or can get it if you
  160. want it, that you can change the software or use pieces of it in new
  161. free programs, and that you know you can do these things.
  162. To protect your rights, we need to prevent others from denying you
  163. these rights or asking you to surrender the rights. Therefore, you have
  164. certain responsibilities if you distribute copies of the software, or if
  165. you modify it: responsibilities to respect the freedom of others.
  166. For example, if you distribute copies of such a program, whether
  167. gratis or for a fee, you must pass on to the recipients the same
  168. freedoms that you received. You must make sure that they, too, receive
  169. or can get the source code. And you must show them these terms so they
  170. know their rights.
  171. Developers that use the GNU GPL protect your rights with two steps:
  172. (1) assert copyright on the software, and (2) offer you this License
  173. giving you legal permission to copy, distribute and/or modify it.
  174. For the developers' and authors' protection, the GPL clearly explains
  175. that there is no warranty for this free software. For both users' and
  176. authors' sake, the GPL requires that modified versions be marked as
  177. changed, so that their problems will not be attributed erroneously to
  178. authors of previous versions.
  179. Some devices are designed to deny users access to install or run
  180. modified versions of the software inside them, although the manufacturer
  181. can do so. This is fundamentally incompatible with the aim of
  182. protecting users' freedom to change the software. The systematic
  183. pattern of such abuse occurs in the area of products for individuals to
  184. use, which is precisely where it is most unacceptable. Therefore, we
  185. have designed this version of the GPL to prohibit the practice for those
  186. products. If such problems arise substantially in other domains, we
  187. stand ready to extend this provision to those domains in future versions
  188. of the GPL, as needed to protect the freedom of users.
  189. Finally, every program is threatened constantly by software patents.
  190. States should not allow patents to restrict development and use of
  191. software on general-purpose computers, but in those that do, we wish to
  192. avoid the special danger that patents applied to a free program could
  193. make it effectively proprietary. To prevent this, the GPL assures that
  194. patents cannot be used to render the program non-free.
  195. The precise terms and conditions for copying, distribution and
  196. modification follow.
  197. TERMS AND CONDITIONS
  198. 0. Definitions.
  199. "This License" refers to version 3 of the GNU General Public License.
  200. "Copyright" also means copyright-like laws that apply to other kinds of
  201. works, such as semiconductor masks.
  202. "The Program" refers to any copyrightable work licensed under this
  203. License. Each licensee is addressed as "you". "Licensees" and
  204. "recipients" may be individuals or organizations.
  205. To "modify" a work means to copy from or adapt all or part of the work
  206. in a fashion requiring copyright permission, other than the making of an
  207. exact copy. The resulting work is called a "modified version" of the
  208. earlier work or a work "based on" the earlier work.
  209. A "covered work" means either the unmodified Program or a work based
  210. on the Program.
  211. To "propagate" a work means to do anything with it that, without
  212. permission, would make you directly or secondarily liable for
  213. infringement under applicable copyright law, except executing it on a
  214. computer or modifying a private copy. Propagation includes copying,
  215. distribution (with or without modification), making available to the
  216. public, and in some countries other activities as well.
  217. To "convey" a work means any kind of propagation that enables other
  218. parties to make or receive copies. Mere interaction with a user through
  219. a computer network, with no transfer of a copy, is not conveying.
  220. An interactive user interface displays "Appropriate Legal Notices"
  221. to the extent that it includes a convenient and prominently visible
  222. feature that (1) displays an appropriate copyright notice, and (2)
  223. tells the user that there is no warranty for the work (except to the
  224. extent that warranties are provided), that licensees may convey the
  225. work under this License, and how to view a copy of this License. If
  226. the interface presents a list of user commands or options, such as a
  227. menu, a prominent item in the list meets this criterion.
  228. 1. Source Code.
  229. The "source code" for a work means the preferred form of the work
  230. for making modifications to it. "Object code" means any non-source
  231. form of a work.
  232. A "Standard Interface" means an interface that either is an official
  233. standard defined by a recognized standards body, or, in the case of
  234. interfaces specified for a particular programming language, one that
  235. is widely used among developers working in that language.
  236. The "System Libraries" of an executable work include anything, other
  237. than the work as a whole, that (a) is included in the normal form of
  238. packaging a Major Component, but which is not part of that Major
  239. Component, and (b) serves only to enable use of the work with that
  240. Major Component, or to implement a Standard Interface for which an
  241. implementation is available to the public in source code form. A
  242. "Major Component", in this context, means a major essential component
  243. (kernel, window system, and so on) of the specific operating system
  244. (if any) on which the executable work runs, or a compiler used to
  245. produce the work, or an object code interpreter used to run it.
  246. The "Corresponding Source" for a work in object code form means all
  247. the source code needed to generate, install, and (for an executable
  248. work) run the object code and to modify the work, including scripts to
  249. control those activities. However, it does not include the work's
  250. System Libraries, or general-purpose tools or generally available free
  251. programs which are used unmodified in performing those activities but
  252. which are not part of the work. For example, Corresponding Source
  253. includes interface definition files associated with source files for
  254. the work, and the source code for shared libraries and dynamically
  255. linked subprograms that the work is specifically designed to require,
  256. such as by intimate data communication or control flow between those
  257. subprograms and other parts of the work.
  258. The Corresponding Source need not include anything that users
  259. can regenerate automatically from other parts of the Corresponding
  260. Source.
  261. The Corresponding Source for a work in source code form is that
  262. same work.
  263. 2. Basic Permissions.
  264. All rights granted under this License are granted for the term of
  265. copyright on the Program, and are irrevocable provided the stated
  266. conditions are met. This License explicitly affirms your unlimited
  267. permission to run the unmodified Program. The output from running a
  268. covered work is covered by this License only if the output, given its
  269. content, constitutes a covered work. This License acknowledges your
  270. rights of fair use or other equivalent, as provided by copyright law.
  271. You may make, run and propagate covered works that you do not
  272. convey, without conditions so long as your license otherwise remains
  273. in force. You may convey covered works to others for the sole purpose
  274. of having them make modifications exclusively for you, or provide you
  275. with facilities for running those works, provided that you comply with
  276. the terms of this License in conveying all material for which you do
  277. not control copyright. Those thus making or running the covered works
  278. for you must do so exclusively on your behalf, under your direction
  279. and control, on terms that prohibit them from making any copies of
  280. your copyrighted material outside their relationship with you.
  281. Conveying under any other circumstances is permitted solely under
  282. the conditions stated below. Sublicensing is not allowed; section 10
  283. makes it unnecessary.
  284. 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
  285. No covered work shall be deemed part of an effective technological
  286. measure under any applicable law fulfilling obligations under article
  287. 11 of the WIPO copyright treaty adopted on 20 December 1996, or
  288. similar laws prohibiting or restricting circumvention of such
  289. measures.
  290. When you convey a covered work, you waive any legal power to forbid
  291. circumvention of technological measures to the extent such circumvention
  292. is effected by exercising rights under this License with respect to
  293. the covered work, and you disclaim any intention to limit operation or
  294. modification of the work as a means of enforcing, against the work's
  295. users, your or third parties' legal rights to forbid circumvention of
  296. technological measures.
  297. 4. Conveying Verbatim Copies.
  298. You may convey verbatim copies of the Program's source code as you
  299. receive it, in any medium, provided that you conspicuously and
  300. appropriately publish on each copy an appropriate copyright notice;
  301. keep intact all notices stating that this License and any
  302. non-permissive terms added in accord with section 7 apply to the code;
  303. keep intact all notices of the absence of any warranty; and give all
  304. recipients a copy of this License along with the Program.
  305. You may charge any price or no price for each copy that you convey,
  306. and you may offer support or warranty protection for a fee.
  307. 5. Conveying Modified Source Versions.
  308. You may convey a work based on the Program, or the modifications to
  309. produce it from the Program, in the form of source code under the
  310. terms of section 4, provided that you also meet all of these conditions:
  311. a) The work must carry prominent notices stating that you modified
  312. it, and giving a relevant date.
  313. b) The work must carry prominent notices stating that it is
  314. released under this License and any conditions added under section
  315. 7. This requirement modifies the requirement in section 4 to
  316. "keep intact all notices".
  317. c) You must license the entire work, as a whole, under this
  318. License to anyone who comes into possession of a copy. This
  319. License will therefore apply, along with any applicable section 7
  320. additional terms, to the whole of the work, and all its parts,
  321. regardless of how they are packaged. This License gives no
  322. permission to license the work in any other way, but it does not
  323. invalidate such permission if you have separately received it.
  324. d) If the work has interactive user interfaces, each must display
  325. Appropriate Legal Notices; however, if the Program has interactive
  326. interfaces that do not display Appropriate Legal Notices, your
  327. work need not make them do so.
  328. A compilation of a covered work with other separate and independent
  329. works, which are not by their nature extensions of the covered work,
  330. and which are not combined with it such as to form a larger program,
  331. in or on a volume of a storage or distribution medium, is called an
  332. "aggregate" if the compilation and its resulting copyright are not
  333. used to limit the access or legal rights of the compilation's users
  334. beyond what the individual works permit. Inclusion of a covered work
  335. in an aggregate does not cause this License to apply to the other
  336. parts of the aggregate.
  337. 6. Conveying Non-Source Forms.
  338. You may convey a covered work in object code form under the terms
  339. of sections 4 and 5, provided that you also convey the
  340. machine-readable Corresponding Source under the terms of this License,
  341. in one of these ways:
  342. a) Convey the object code in, or embodied in, a physical product
  343. (including a physical distribution medium), accompanied by the
  344. Corresponding Source fixed on a durable physical medium
  345. customarily used for software interchange.
  346. b) Convey the object code in, or embodied in, a physical product
  347. (including a physical distribution medium), accompanied by a
  348. written offer, valid for at least three years and valid for as
  349. long as you offer spare parts or customer support for that product
  350. model, to give anyone who possesses the object code either (1) a
  351. copy of the Corresponding Source for all the software in the
  352. product that is covered by this License, on a durable physical
  353. medium customarily used for software interchange, for a price no
  354. more than your reasonable cost of physically performing this
  355. conveying of source, or (2) access to copy the
  356. Corresponding Source from a network server at no charge.
  357. c) Convey individual copies of the object code with a copy of the
  358. written offer to provide the Corresponding Source. This
  359. alternative is allowed only occasionally and noncommercially, and
  360. only if you received the object code with such an offer, in accord
  361. with subsection 6b.
  362. d) Convey the object code by offering access from a designated
  363. place (gratis or for a charge), and offer equivalent access to the
  364. Corresponding Source in the same way through the same place at no
  365. further charge. You need not require recipients to copy the
  366. Corresponding Source along with the object code. If the place to
  367. copy the object code is a network server, the Corresponding Source
  368. may be on a different server (operated by you or a third party)
  369. that supports equivalent copying facilities, provided you maintain
  370. clear directions next to the object code saying where to find the
  371. Corresponding Source. Regardless of what server hosts the
  372. Corresponding Source, you remain obligated to ensure that it is
  373. available for as long as needed to satisfy these requirements.
  374. e) Convey the object code using peer-to-peer transmission, provided
  375. you inform other peers where the object code and Corresponding
  376. Source of the work are being offered to the general public at no
  377. charge under subsection 6d.
  378. A separable portion of the object code, whose source code is excluded
  379. from the Corresponding Source as a System Library, need not be
  380. included in conveying the object code work.
  381. A "User Product" is either (1) a "consumer product", which means any
  382. tangible personal property which is normally used for personal, family,
  383. or household purposes, or (2) anything designed or sold for incorporation
  384. into a dwelling. In determining whether a product is a consumer product,
  385. doubtful cases shall be resolved in favor of coverage. For a particular
  386. product received by a particular user, "normally used" refers to a
  387. typical or common use of that class of product, regardless of the status
  388. of the particular user or of the way in which the particular user
  389. actually uses, or expects or is expected to use, the product. A product
  390. is a consumer product regardless of whether the product has substantial
  391. commercial, industrial or non-consumer uses, unless such uses represent
  392. the only significant mode of use of the product.
  393. "Installation Information" for a User Product means any methods,
  394. procedures, authorization keys, or other information required to install
  395. and execute modified versions of a covered work in that User Product from
  396. a modified version of its Corresponding Source. The information must
  397. suffice to ensure that the continued functioning of the modified object
  398. code is in no case prevented or interfered with solely because
  399. modification has been made.
  400. If you convey an object code work under this section in, or with, or
  401. specifically for use in, a User Product, and the conveying occurs as
  402. part of a transaction in which the right of possession and use of the
  403. User Product is transferred to the recipient in perpetuity or for a
  404. fixed term (regardless of how the transaction is characterized), the
  405. Corresponding Source conveyed under this section must be accompanied
  406. by the Installation Information. But this requirement does not apply
  407. if neither you nor any third party retains the ability to install
  408. modified object code on the User Product (for example, the work has
  409. been installed in ROM).
  410. The requirement to provide Installation Information does not include a
  411. requirement to continue to provide support service, warranty, or updates
  412. for a work that has been modified or installed by the recipient, or for
  413. the User Product in which it has been modified or installed. Access to a
  414. network may be denied when the modification itself materially and
  415. adversely affects the operation of the network or violates the rules and
  416. protocols for communication across the network.
  417. Corresponding Source conveyed, and Installation Information provided,
  418. in accord with this section must be in a format that is publicly
  419. documented (and with an implementation available to the public in
  420. source code form), and must require no special password or key for
  421. unpacking, reading or copying.
  422. 7. Additional Terms.
  423. "Additional permissions" are terms that supplement the terms of this
  424. License by making exceptions from one or more of its conditions.
  425. Additional permissions that are applicable to the entire Program shall
  426. be treated as though they were included in this License, to the extent
  427. that they are valid under applicable law. If additional permissions
  428. apply only to part of the Program, that part may be used separately
  429. under those permissions, but the entire Program remains governed by
  430. this License without regard to the additional permissions.
  431. When you convey a copy of a covered work, you may at your option
  432. remove any additional permissions from that copy, or from any part of
  433. it. (Additional permissions may be written to require their own
  434. removal in certain cases when you modify the work.) You may place
  435. additional permissions on material, added by you to a covered work,
  436. for which you have or can give appropriate copyright permission.
  437. Notwithstanding any other provision of this License, for material you
  438. add to a covered work, you may (if authorized by the copyright holders of
  439. that material) supplement the terms of this License with terms:
  440. a) Disclaiming warranty or limiting liability differently from the
  441. terms of sections 15 and 16 of this License; or
  442. b) Requiring preservation of specified reasonable legal notices or
  443. author attributions in that material or in the Appropriate Legal
  444. Notices displayed by works containing it; or
  445. c) Prohibiting misrepresentation of the origin of that material, or
  446. requiring that modified versions of such material be marked in
  447. reasonable ways as different from the original version; or
  448. d) Limiting the use for publicity purposes of names of licensors or
  449. authors of the material; or
  450. e) Declining to grant rights under trademark law for use of some
  451. trade names, trademarks, or service marks; or
  452. f) Requiring indemnification of licensors and authors of that
  453. material by anyone who conveys the material (or modified versions of
  454. it) with contractual assumptions of liability to the recipient, for
  455. any liability that these contractual assumptions directly impose on
  456. those licensors and authors.
  457. All other non-permissive additional terms are considered "further
  458. restrictions" within the meaning of section 10. If the Program as you
  459. received it, or any part of it, contains a notice stating that it is
  460. governed by this License along with a term that is a further
  461. restriction, you may remove that term. If a license document contains
  462. a further restriction but permits relicensing or conveying under this
  463. License, you may add to a covered work material governed by the terms
  464. of that license document, provided that the further restriction does
  465. not survive such relicensing or conveying.
  466. If you add terms to a covered work in accord with this section, you
  467. must place, in the relevant source files, a statement of the
  468. additional terms that apply to those files, or a notice indicating
  469. where to find the applicable terms.
  470. Additional terms, permissive or non-permissive, may be stated in the
  471. form of a separately written license, or stated as exceptions;
  472. the above requirements apply either way.
  473. 8. Termination.
  474. You may not propagate or modify a covered work except as expressly
  475. provided under this License. Any attempt otherwise to propagate or
  476. modify it is void, and will automatically terminate your rights under
  477. this License (including any patent licenses granted under the third
  478. paragraph of section 11).
  479. However, if you cease all violation of this License, then your
  480. license from a particular copyright holder is reinstated (a)
  481. provisionally, unless and until the copyright holder explicitly and
  482. finally terminates your license, and (b) permanently, if the copyright
  483. holder fails to notify you of the violation by some reasonable means
  484. prior to 60 days after the cessation.
  485. Moreover, your license from a particular copyright holder is
  486. reinstated permanently if the copyright holder notifies you of the
  487. violation by some reasonable means, this is the first time you have
  488. received notice of violation of this License (for any work) from that
  489. copyright holder, and you cure the violation prior to 30 days after
  490. your receipt of the notice.
  491. Termination of your rights under this section does not terminate the
  492. licenses of parties who have received copies or rights from you under
  493. this License. If your rights have been terminated and not permanently
  494. reinstated, you do not qualify to receive new licenses for the same
  495. material under section 10.
  496. 9. Acceptance Not Required for Having Copies.
  497. You are not required to accept this License in order to receive or
  498. run a copy of the Program. Ancillary propagation of a covered work
  499. occurring solely as a consequence of using peer-to-peer transmission
  500. to receive a copy likewise does not require acceptance. However,
  501. nothing other than this License grants you permission to propagate or
  502. modify any covered work. These actions infringe copyright if you do
  503. not accept this License. Therefore, by modifying or propagating a
  504. covered work, you indicate your acceptance of this License to do so.
  505. 10. Automatic Licensing of Downstream Recipients.
  506. Each time you convey a covered work, the recipient automatically
  507. receives a license from the original licensors, to run, modify and
  508. propagate that work, subject to this License. You are not responsible
  509. for enforcing compliance by third parties with this License.
  510. An "entity transaction" is a transaction transferring control of an
  511. organization, or substantially all assets of one, or subdividing an
  512. organization, or merging organizations. If propagation of a covered
  513. work results from an entity transaction, each party to that
  514. transaction who receives a copy of the work also receives whatever
  515. licenses to the work the party's predecessor in interest had or could
  516. give under the previous paragraph, plus a right to possession of the
  517. Corresponding Source of the work from the predecessor in interest, if
  518. the predecessor has it or can get it with reasonable efforts.
  519. You may not impose any further restrictions on the exercise of the
  520. rights granted or affirmed under this License. For example, you may
  521. not impose a license fee, royalty, or other charge for exercise of
  522. rights granted under this License, and you may not initiate litigation
  523. (including a cross-claim or counterclaim in a lawsuit) alleging that
  524. any patent claim is infringed by making, using, selling, offering for
  525. sale, or importing the Program or any portion of it.
  526. 11. Patents.
  527. A "contributor" is a copyright holder who authorizes use under this
  528. License of the Program or a work on which the Program is based. The
  529. work thus licensed is called the contributor's "contributor version".
  530. A contributor's "essential patent claims" are all patent claims
  531. owned or controlled by the contributor, whether already acquired or
  532. hereafter acquired, that would be infringed by some manner, permitted
  533. by this License, of making, using, or selling its contributor version,
  534. but do not include claims that would be infringed only as a
  535. consequence of further modification of the contributor version. For
  536. purposes of this definition, "control" includes the right to grant
  537. patent sublicenses in a manner consistent with the requirements of
  538. this License.
  539. Each contributor grants you a non-exclusive, worldwide, royalty-free
  540. patent license under the contributor's essential patent claims, to
  541. make, use, sell, offer for sale, import and otherwise run, modify and
  542. propagate the contents of its contributor version.
  543. In the following three paragraphs, a "patent license" is any express
  544. agreement or commitment, however denominated, not to enforce a patent
  545. (such as an express permission to practice a patent or covenant not to
  546. sue for patent infringement). To "grant" such a patent license to a
  547. party means to make such an agreement or commitment not to enforce a
  548. patent against the party.
  549. If you convey a covered work, knowingly relying on a patent license,
  550. and the Corresponding Source of the work is not available for anyone
  551. to copy, free of charge and under the terms of this License, through a
  552. publicly available network server or other readily accessible means,
  553. then you must either (1) cause the Corresponding Source to be so
  554. available, or (2) arrange to deprive yourself of the benefit of the
  555. patent license for this particular work, or (3) arrange, in a manner
  556. consistent with the requirements of this License, to extend the patent
  557. license to downstream recipients. "Knowingly relying" means you have
  558. actual knowledge that, but for the patent license, your conveying the
  559. covered work in a country, or your recipient's use of the covered work
  560. in a country, would infringe one or more identifiable patents in that
  561. country that you have reason to believe are valid.
  562. If, pursuant to or in connection with a single transaction or
  563. arrangement, you convey, or propagate by procuring conveyance of, a
  564. covered work, and grant a patent license to some of the parties
  565. receiving the covered work authorizing them to use, propagate, modify
  566. or convey a specific copy of the covered work, then the patent license
  567. you grant is automatically extended to all recipients of the covered
  568. work and works based on it.
  569. A patent license is "discriminatory" if it does not include within
  570. the scope of its coverage, prohibits the exercise of, or is
  571. conditioned on the non-exercise of one or more of the rights that are
  572. specifically granted under this License. You may not convey a covered
  573. work if you are a party to an arrangement with a third party that is
  574. in the business of distributing software, under which you make payment
  575. to the third party based on the extent of your activity of conveying
  576. the work, and under which the third party grants, to any of the
  577. parties who would receive the covered work from you, a discriminatory
  578. patent license (a) in connection with copies of the covered work
  579. conveyed by you (or copies made from those copies), or (b) primarily
  580. for and in connection with specific products or compilations that
  581. contain the covered work, unless you entered into that arrangement,
  582. or that patent license was granted, prior to 28 March 2007.
  583. Nothing in this License shall be construed as excluding or limiting
  584. any implied license or other defenses to infringement that may
  585. otherwise be available to you under applicable patent law.
  586. 12. No Surrender of Others' Freedom.
  587. If conditions are imposed on you (whether by court order, agreement or
  588. otherwise) that contradict the conditions of this License, they do not
  589. excuse you from the conditions of this License. If you cannot convey a
  590. covered work so as to satisfy simultaneously your obligations under this
  591. License and any other pertinent obligations, then as a consequence you may
  592. not convey it at all. For example, if you agree to terms that obligate you
  593. to collect a royalty for further conveying from those to whom you convey
  594. the Program, the only way you could satisfy both those terms and this
  595. License would be to refrain entirely from conveying the Program.
  596. 13. Use with the GNU Affero General Public License.
  597. Notwithstanding any other provision of this License, you have
  598. permission to link or combine any covered work with a work licensed
  599. under version 3 of the GNU Affero General Public License into a single
  600. combined work, and to convey the resulting work. The terms of this
  601. License will continue to apply to the part which is the covered work,
  602. but the special requirements of the GNU Affero General Public License,
  603. section 13, concerning interaction through a network will apply to the
  604. combination as such.
  605. 14. Revised Versions of this License.
  606. The Free Software Foundation may publish revised and/or new versions of
  607. the GNU General Public License from time to time. Such new versions will
  608. be similar in spirit to the present version, but may differ in detail to
  609. address new problems or concerns.
  610. Each version is given a distinguishing version number. If the
  611. Program specifies that a certain numbered version of the GNU General
  612. Public License "or any later version" applies to it, you have the
  613. option of following the terms and conditions either of that numbered
  614. version or of any later version published by the Free Software
  615. Foundation. If the Program does not specify a version number of the
  616. GNU General Public License, you may choose any version ever published
  617. by the Free Software Foundation.
  618. If the Program specifies that a proxy can decide which future
  619. versions of the GNU General Public License can be used, that proxy's
  620. public statement of acceptance of a version permanently authorizes you
  621. to choose that version for the Program.
  622. Later license versions may give you additional or different
  623. permissions. However, no additional obligations are imposed on any
  624. author or copyright holder as a result of your choosing to follow a
  625. later version.
  626. 15. Disclaimer of Warranty.
  627. THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
  628. APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
  629. HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
  630. OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
  631. THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
  632. PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
  633. IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
  634. ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
  635. 16. Limitation of Liability.
  636. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
  637. WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
  638. THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
  639. GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
  640. USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
  641. DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
  642. PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
  643. EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
  644. SUCH DAMAGES.
  645. 17. Interpretation of Sections 15 and 16.
  646. If the disclaimer of warranty and limitation of liability provided
  647. above cannot be given local legal effect according to their terms,
  648. reviewing courts shall apply local law that most closely approximates
  649. an absolute waiver of all civil liability in connection with the
  650. Program, unless a warranty or assumption of liability accompanies a
  651. copy of the Program in return for a fee.
  652. END OF TERMS AND CONDITIONS
  653. How to Apply These Terms to Your New Programs
  654. If you develop a new program, and you want it to be of the greatest
  655. possible use to the public, the best way to achieve this is to make it
  656. free software which everyone can redistribute and change under these terms.
  657. To do so, attach the following notices to the program. It is safest
  658. to attach them to the start of each source file to most effectively
  659. state the exclusion of warranty; and each file should have at least
  660. the "copyright" line and a pointer to where the full notice is found.
  661. <one line to give the program's name and a brief idea of what it does.>
  662. Copyright (C) <year> <name of author>
  663. This program is free software: you can redistribute it and/or modify
  664. it under the terms of the GNU General Public License as published by
  665. the Free Software Foundation, either version 3 of the License, or
  666. (at your option) any later version.
  667. This program is distributed in the hope that it will be useful,
  668. but WITHOUT ANY WARRANTY; without even the implied warranty of
  669. MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
  670. GNU General Public License for more details.
  671. You should have received a copy of the GNU General Public License
  672. along with this program. If not, see <http://www.gnu.org/licenses/>.
  673. Also add information on how to contact you by electronic and paper mail.
  674. If the program does terminal interaction, make it output a short
  675. notice like this when it starts in an interactive mode:
  676. <program> Copyright (C) <year> <name of author>
  677. This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
  678. This is free software, and you are welcome to redistribute it
  679. under certain conditions; type `show c' for details.
  680. The hypothetical commands `show w' and `show c' should show the appropriate
  681. parts of the General Public License. Of course, your program's commands
  682. might be different; for a GUI interface, you would use an "about box".
  683. You should also get your employer (if you work as a programmer) or school,
  684. if any, to sign a "copyright disclaimer" for the program, if necessary.
  685. For more information on this, and how to apply and follow the GNU GPL, see
  686. <http://www.gnu.org/licenses/>.
  687. The GNU General Public License does not permit incorporating your program
  688. into proprietary programs. If your program is a subroutine library, you
  689. may consider it more useful to permit linking proprietary applications with
  690. the library. If this is what you want to do, use the GNU Lesser General
  691. Public License instead of this License. But first, please read
  692. <http://www.gnu.org/philosophy/why-not-lgpl.html>.
