1BioPerl is licensed under the same terms as Perl itself, which means it is 2dually-licensed under either the Artistic or GPL licenses. 3 4Below are details of the Artistic License and, following it, the GPL. 5 6 7 The "Artistic License" 8 9 Preamble 10 11The intent of this document is to state the conditions under which a 12Package may be copied, such that the Copyright Holder maintains some 13semblance of artistic control over the development of the package, 14while giving the users of the package the right to use and distribute 15the Package in a more-or-less customary fashion, plus the right to make 16reasonable modifications. 17 18Definitions: 19 20 "Package" refers to the collection of files distributed by the 21 Copyright Holder, and derivatives of that collection of files 22 created through textual modification. 23 24 "Standard Version" refers to such a Package if it has not been 25 modified, or has been modified in accordance with the wishes 26 of the Copyright Holder as specified below. 27 28 "Copyright Holder" is whoever is named in the copyright or 29 copyrights for the package. 30 31 "You" is you, if you're thinking about copying or distributing 32 this Package. 33 34 "Reasonable copying fee" is whatever you can justify on the 35 basis of media cost, duplication charges, time of people involved, 36 and so on. (You will not be required to justify it to the 37 Copyright Holder, but only to the computing community at large 38 as a market that must bear the fee.) 39 40 "Freely Available" means that no fee is charged for the item 41 itself, though there may be fees involved in handling the item. 42 It also means that recipients of the item may redistribute it 43 under the same conditions they received it. 44 451. You may make and give away verbatim copies of the source form of the 46Standard Version of this Package without restriction, provided that you 47duplicate all of the original copyright notices and associated disclaimers. 48 492. You may apply bug fixes, portability fixes and other modifications 50derived from the Public Domain or from the Copyright Holder. A Package 51modified in such a way shall still be considered the Standard Version. 52 533. You may otherwise modify your copy of this Package in any way, provided 54that you insert a prominent notice in each changed file stating how and 55when you changed that file, and provided that you do at least ONE of the 56following: 57 58 a) place your modifications in the Public Domain or otherwise make them 59 Freely Available, such as by posting said modifications to Usenet or 60 an equivalent medium, or placing the modifications on a major archive 61 site such as uunet.uu.net, or by allowing the Copyright Holder to include 62 your modifications in the Standard Version of the Package. 63 64 b) use the modified Package only within your corporation or organization. 65 66 c) rename any non-standard executables so the names do not conflict 67 with standard executables, which must also be provided, and provide 68 a separate manual page for each non-standard executable that clearly 69 documents how it differs from the Standard Version. 70 71 d) make other distribution arrangements with the Copyright Holder. 72 734. You may distribute the programs of this Package in object code or 74executable form, provided that you do at least ONE of the following: 75 76 a) distribute a Standard Version of the executables and library files, 77 together with instructions (in the manual page or equivalent) on where 78 to get the Standard Version. 79 80 b) accompany the distribution with the machine-readable source of 81 the Package with your modifications. 82 83 c) give non-standard executables non-standard names, and clearly 84 document the differences in manual pages (or equivalent), together 85 with instructions on where to get the Standard Version. 86 87 d) make other distribution arrangements with the Copyright Holder. 88 895. You may charge a reasonable copying fee for any distribution of this 90Package. You may charge any fee you choose for support of this 91Package. You may not charge a fee for this Package itself. However, 92you may distribute this Package in aggregate with other (possibly 93commercial) programs as part of a larger (possibly commercial) software 94distribution provided that you do not advertise this Package as a 95product of your own. You may embed this Package's interpreter within 96an executable of yours (by linking); this shall be construed as a mere 97form of aggregation, provided that the complete Standard Version of the 98interpreter is so embedded. 99 1006. The scripts and library files supplied as input to or produced as 101output from the programs of this Package do not automatically fall 102under the copyright of this Package, but belong to whoever generated 103them, and may be sold commercially, and may be aggregated with this 104Package. If such scripts or library files are aggregated with this 105Package via the so-called "undump" or "unexec" methods of producing a 106binary executable image, then distribution of such an image shall 107neither be construed as a distribution of this Package nor shall it 108fall under the restrictions of Paragraphs 3 and 4, provided that you do 109not represent such an executable image as a Standard Version of this 110Package. 111 1127. C subroutines (or comparably compiled subroutines in other 113languages) supplied by you and linked into this Package in order to 114emulate subroutines and variables of the language defined by this 115Package shall not be considered part of this Package, but are the 116equivalent of input as in Paragraph 6, provided these subroutines do 117not change the language in any way that would cause it to fail the 118regression tests for the language. 119 1208. Aggregation of this Package with a commercial distribution is always 121permitted provided that the use of this Package is embedded; that is, 122when no overt attempt is made to make this Package's interfaces visible 123to the end user of the commercial distribution. Such use shall not be 124construed as a distribution of this Package. 125 1269. The name of the Copyright Holder may not be used to endorse or promote 127products derived from this software without specific prior written permission. 128 12910. THIS PACKAGE IS PROVIDED "AS IS" AND WITHOUT ANY EXPRESS OR 130IMPLIED WARRANTIES, INCLUDING, WITHOUT LIMITATION, THE IMPLIED 131WARRANTIES OF MERCHANTIBILITY AND FITNESS FOR A PARTICULAR PURPOSE. 132 133 The End 134 135 136 137 138 139GNU GENERAL PUBLIC LICENSE 140 Version 3, 29 June 2007 141 142 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. 145 146 Preamble 147 148 The GNU General Public License is a free, copyleft license for 149software and other kinds of works. 150 151 The licenses for most software and other practical works are designed 152to take away your freedom to share and change the works. By contrast, 153the GNU General Public License is intended to guarantee your freedom to 154share and change all versions of a program--to make sure it remains free 155software for all its users. We, the Free Software Foundation, use the 156GNU General Public License for most of our software; it applies also to 157any other work released this way by its authors. You can apply it to 158your programs, too. 159 160 When we speak of free software, we are referring to freedom, not 161price. Our General Public Licenses are designed to make sure that you 162have the freedom to distribute copies of free software (and charge for 163them if you wish), that you receive source code or can get it if you 164want it, that you can change the software or use pieces of it in new 165free programs, and that you know you can do these things. 166 167 To protect your rights, we need to prevent others from denying you 168these rights or asking you to surrender the rights. Therefore, you have 169certain responsibilities if you distribute copies of the software, or if 170you modify it: responsibilities to respect the freedom of others. 171 172 For example, if you distribute copies of such a program, whether 173gratis or for a fee, you must pass on to the recipients the same 174freedoms that you received. You must make sure that they, too, receive 175or can get the source code. And you must show them these terms so they 176know their rights. 177 178 Developers that use the GNU GPL protect your rights with two steps: 179(1) assert copyright on the software, and (2) offer you this License 180giving you legal permission to copy, distribute and/or modify it. 181 182 For the developers' and authors' protection, the GPL clearly explains 183that there is no warranty for this free software. For both users' and 184authors' sake, the GPL requires that modified versions be marked as 185changed, so that their problems will not be attributed erroneously to 186authors of previous versions. 187 188 Some devices are designed to deny users access to install or run 189modified versions of the software inside them, although the manufacturer 190can do so. This is fundamentally incompatible with the aim of 191protecting users' freedom to change the software. The systematic 192pattern of such abuse occurs in the area of products for individuals to 193use, which is precisely where it is most unacceptable. Therefore, we 194have designed this version of the GPL to prohibit the practice for those 195products. If such problems arise substantially in other domains, we 196stand ready to extend this provision to those domains in future versions 197of the GPL, as needed to protect the freedom of users. 198 199 Finally, every program is threatened constantly by software patents. 200States should not allow patents to restrict development and use of 201software on general-purpose computers, but in those that do, we wish to 202avoid the special danger that patents applied to a free program could 203make it effectively proprietary. To prevent this, the GPL assures that 204patents cannot be used to render the program non-free. 205 206 The precise terms and conditions for copying, distribution and 207modification follow. 208 209 TERMS AND CONDITIONS 210 211 0. Definitions. 212 213 "This License" refers to version 3 of the GNU General Public License. 214 215 "Copyright" also means copyright-like laws that apply to other kinds of 216works, such as semiconductor masks. 217 218 "The Program" refers to any copyrightable work licensed under this 219License. Each licensee is addressed as "you". "Licensees" and 220"recipients" may be individuals or organizations. 221 222 To "modify" a work means to copy from or adapt all or part of the work 223in a fashion requiring copyright permission, other than the making of an 224exact copy. The resulting work is called a "modified version" of the 225earlier work or a work "based on" the earlier work. 226 227 A "covered work" means either the unmodified Program or a work based 228on the Program. 229 230 To "propagate" a work means to do anything with it that, without 231permission, would make you directly or secondarily liable for 232infringement under applicable copyright law, except executing it on a 233computer or modifying a private copy. Propagation includes copying, 234distribution (with or without modification), making available to the 235public, and in some countries other activities as well. 236 237 To "convey" a work means any kind of propagation that enables other 238parties to make or receive copies. Mere interaction with a user through 239a computer network, with no transfer of a copy, is not conveying. 240 241 An interactive user interface displays "Appropriate Legal Notices" 242to the extent that it includes a convenient and prominently visible 243feature that (1) displays an appropriate copyright notice, and (2) 244tells the user that there is no warranty for the work (except to the 245extent that warranties are provided), that licensees may convey the 246work under this License, and how to view a copy of this License. If 247the interface presents a list of user commands or options, such as a 248menu, a prominent item in the list meets this criterion. 249 250 1. Source Code. 251 252 The "source code" for a work means the preferred form of the work 253for making modifications to it. "Object code" means any non-source 254form of a work. 255 256 A "Standard Interface" means an interface that either is an official 257standard defined by a recognized standards body, or, in the case of 258interfaces specified for a particular programming language, one that 259is widely used among developers working in that language. 260 261 The "System Libraries" of an executable work include anything, other 262than the work as a whole, that (a) is included in the normal form of 263packaging a Major Component, but which is not part of that Major 264Component, and (b) serves only to enable use of the work with that 265Major Component, or to implement a Standard Interface for which an 266implementation is available to the public in source code form. A 267"Major Component", in this context, means a major essential component 268(kernel, window system, and so on) of the specific operating system 269(if any) on which the executable work runs, or a compiler used to 270produce the work, or an object code interpreter used to run it. 271 272 The "Corresponding Source" for a work in object code form means all 273the source code needed to generate, install, and (for an executable 274work) run the object code and to modify the work, including scripts to 275control those activities. However, it does not include the work's 276System Libraries, or general-purpose tools or generally available free 277programs which are used unmodified in performing those activities but 278which are not part of the work. For example, Corresponding Source 279includes interface definition files associated with source files for 280the work, and the source code for shared libraries and dynamically 281linked subprograms that the work is specifically designed to require, 282such as by intimate data communication or control flow between those 283subprograms and other parts of the work. 284 285 The Corresponding Source need not include anything that users 286can regenerate automatically from other parts of the Corresponding 287Source. 288 289 The Corresponding Source for a work in source code form is that 290same work. 291 292 2. Basic Permissions. 293 294 All rights granted under this License are granted for the term of 295copyright on the Program, and are irrevocable provided the stated 296conditions are met. This License explicitly affirms your unlimited 297permission to run the unmodified Program. The output from running a 298covered work is covered by this License only if the output, given its 299content, constitutes a covered work. This License acknowledges your 300rights of fair use or other equivalent, as provided by copyright law. 301 302 You may make, run and propagate covered works that you do not 303convey, without conditions so long as your license otherwise remains 304in force. You may convey covered works to others for the sole purpose 305of having them make modifications exclusively for you, or provide you 306with facilities for running those works, provided that you comply with 307the terms of this License in conveying all material for which you do 308not control copyright. Those thus making or running the covered works 309for you must do so exclusively on your behalf, under your direction 310and control, on terms that prohibit them from making any copies of 311your copyrighted material outside their relationship with you. 312 313 Conveying under any other circumstances is permitted solely under 314the conditions stated below. Sublicensing is not allowed; section 10 315makes it unnecessary. 316 317 3. Protecting Users' Legal Rights From Anti-Circumvention Law. 318 319 No covered work shall be deemed part of an effective technological 320measure under any applicable law fulfilling obligations under article 32111 of the WIPO copyright treaty adopted on 20 December 1996, or 322similar laws prohibiting or restricting circumvention of such 323measures. 324 325 When you convey a covered work, you waive any legal power to forbid 326circumvention of technological measures to the extent such circumvention 327is effected by exercising rights under this License with respect to 328the covered work, and you disclaim any intention to limit operation or 329modification of the work as a means of enforcing, against the work's 330users, your or third parties' legal rights to forbid circumvention of 331technological measures. 332 333 4. Conveying Verbatim Copies. 334 335 You may convey verbatim copies of the Program's source code as you 336receive it, in any medium, provided that you conspicuously and 337appropriately publish on each copy an appropriate copyright notice; 338keep intact all notices stating that this License and any 339non-permissive terms added in accord with section 7 apply to the code; 340keep intact all notices of the absence of any warranty; and give all 341recipients a copy of this License along with the Program. 342 343 You may charge any price or no price for each copy that you convey, 344and you may offer support or warranty protection for a fee. 345 346 5. Conveying Modified Source Versions. 347 348 You may convey a work based on the Program, or the modifications to 349produce it from the Program, in the form of source code under the 350terms of section 4, provided that you also meet all of these conditions: 351 352 a) The work must carry prominent notices stating that you modified 353 it, and giving a relevant date. 354 355 b) The work must carry prominent notices stating that it is 356 released under this License and any conditions added under section 357 7. This requirement modifies the requirement in section 4 to 358 "keep intact all notices". 359 360 c) You must license the entire work, as a whole, under this 361 License to anyone who comes into possession of a copy. This 362 License will therefore apply, along with any applicable section 7 363 additional terms, to the whole of the work, and all its parts, 364 regardless of how they are packaged. This License gives no 365 permission to license the work in any other way, but it does not 366 invalidate such permission if you have separately received it. 367 368 d) If the work has interactive user interfaces, each must display 369 Appropriate Legal Notices; however, if the Program has interactive 370 interfaces that do not display Appropriate Legal Notices, your 371 work need not make them do so. 372 373 A compilation of a covered work with other separate and independent 374works, which are not by their nature extensions of the covered work, 375and which are not combined with it such as to form a larger program, 376in or on a volume of a storage or distribution medium, is called an 377"aggregate" if the compilation and its resulting copyright are not 378used to limit the access or legal rights of the compilation's users 379beyond what the individual works permit. Inclusion of a covered work 380in an aggregate does not cause this License to apply to the other 381parts of the aggregate. 382 383 6. Conveying Non-Source Forms. 384 385 You may convey a covered work in object code form under the terms 386of sections 4 and 5, provided that you also convey the 387machine-readable Corresponding Source under the terms of this License, 388in one of these ways: 389 390 a) Convey the object code in, or embodied in, a physical product 391 (including a physical distribution medium), accompanied by the 392 Corresponding Source fixed on a durable physical medium 393 customarily used for software interchange. 394 395 b) Convey the object code in, or embodied in, a physical product 396 (including a physical distribution medium), accompanied by a 397 written offer, valid for at least three years and valid for as 398 long as you offer spare parts or customer support for that product 399 model, to give anyone who possesses the object code either (1) a 400 copy of the Corresponding Source for all the software in the 401 product that is covered by this License, on a durable physical 402 medium customarily used for software interchange, for a price no 403 more than your reasonable cost of physically performing this 404 conveying of source, or (2) access to copy the 405 Corresponding Source from a network server at no charge. 406 407 c) Convey individual copies of the object code with a copy of the 408 written offer to provide the Corresponding Source. This 409 alternative is allowed only occasionally and noncommercially, and 410 only if you received the object code with such an offer, in accord 411 with subsection 6b. 412 413 d) Convey the object code by offering access from a designated 414 place (gratis or for a charge), and offer equivalent access to the 415 Corresponding Source in the same way through the same place at no 416 further charge. You need not require recipients to copy the 417 Corresponding Source along with the object code. If the place to 418 copy the object code is a network server, the Corresponding Source 419 may be on a different server (operated by you or a third party) 420 that supports equivalent copying facilities, provided you maintain 421 clear directions next to the object code saying where to find the 422 Corresponding Source. Regardless of what server hosts the 423 Corresponding Source, you remain obligated to ensure that it is 424 available for as long as needed to satisfy these requirements. 425 426 e) Convey the object code using peer-to-peer transmission, provided 427 you inform other peers where the object code and Corresponding 428 Source of the work are being offered to the general public at no 429 charge under subsection 6d. 430 431 A separable portion of the object code, whose source code is excluded 432from the Corresponding Source as a System Library, need not be 433included in conveying the object code work. 434 435 A "User Product" is either (1) a "consumer product", which means any 436tangible personal property which is normally used for personal, family, 437or household purposes, or (2) anything designed or sold for incorporation 438into a dwelling. In determining whether a product is a consumer product, 439doubtful cases shall be resolved in favor of coverage. For a particular 440product received by a particular user, "normally used" refers to a 441typical or common use of that class of product, regardless of the status 442of the particular user or of the way in which the particular user 443actually uses, or expects or is expected to use, the product. A product 444is a consumer product regardless of whether the product has substantial 445commercial, industrial or non-consumer uses, unless such uses represent 446the only significant mode of use of the product. 447 448 "Installation Information" for a User Product means any methods, 449procedures, authorization keys, or other information required to install 450and execute modified versions of a covered work in that User Product from 451a modified version of its Corresponding Source. The information must 452suffice to ensure that the continued functioning of the modified object 453code is in no case prevented or interfered with solely because 454modification has been made. 455 456 If you convey an object code work under this section in, or with, or 457specifically for use in, a User Product, and the conveying occurs as 458part of a transaction in which the right of possession and use of the 459User Product is transferred to the recipient in perpetuity or for a 460fixed term (regardless of how the transaction is characterized), the 461Corresponding Source conveyed under this section must be accompanied 462by the Installation Information. But this requirement does not apply 463if neither you nor any third party retains the ability to install 464modified object code on the User Product (for example, the work has 465been installed in ROM). 466 467 The requirement to provide Installation Information does not include a 468requirement to continue to provide support service, warranty, or updates 469for a work that has been modified or installed by the recipient, or for 470the User Product in which it has been modified or installed. Access to a 471network may be denied when the modification itself materially and 472adversely affects the operation of the network or violates the rules and 473protocols for communication across the network. 474 475 Corresponding Source conveyed, and Installation Information provided, 476in accord with this section must be in a format that is publicly 477documented (and with an implementation available to the public in 478source code form), and must require no special password or key for 479unpacking, reading or copying. 480 481 7. Additional Terms. 482 483 "Additional permissions" are terms that supplement the terms of this 484License by making exceptions from one or more of its conditions. 485Additional permissions that are applicable to the entire Program shall 486be treated as though they were included in this License, to the extent 487that they are valid under applicable law. If additional permissions 488apply only to part of the Program, that part may be used separately 489under those permissions, but the entire Program remains governed by 490this License without regard to the additional permissions. 491 492 When you convey a copy of a covered work, you may at your option 493remove any additional permissions from that copy, or from any part of 494it. (Additional permissions may be written to require their own 495removal in certain cases when you modify the work.) You may place 496additional permissions on material, added by you to a covered work, 497for which you have or can give appropriate copyright permission. 498 499 Notwithstanding any other provision of this License, for material you 500add to a covered work, you may (if authorized by the copyright holders of 501that material) supplement the terms of this License with terms: 502 503 a) Disclaiming warranty or limiting liability differently from the 504 terms of sections 15 and 16 of this License; or 505 506 b) Requiring preservation of specified reasonable legal notices or 507 author attributions in that material or in the Appropriate Legal 508 Notices displayed by works containing it; or 509 510 c) Prohibiting misrepresentation of the origin of that material, or 511 requiring that modified versions of such material be marked in 512 reasonable ways as different from the original version; or 513 514 d) Limiting the use for publicity purposes of names of licensors or 515 authors of the material; or 516 517 e) Declining to grant rights under trademark law for use of some 518 trade names, trademarks, or service marks; or 519 520 f) Requiring indemnification of licensors and authors of that 521 material by anyone who conveys the material (or modified versions of 522 it) with contractual assumptions of liability to the recipient, for 523 any liability that these contractual assumptions directly impose on 524 those licensors and authors. 525 526 All other non-permissive additional terms are considered "further 527restrictions" within the meaning of section 10. If the Program as you 528received it, or any part of it, contains a notice stating that it is 529governed by this License along with a term that is a further 530restriction, you may remove that term. If a license document contains 531a further restriction but permits relicensing or conveying under this 532License, you may add to a covered work material governed by the terms 533of that license document, provided that the further restriction does 534not survive such relicensing or conveying. 535 536 If you add terms to a covered work in accord with this section, you 537must place, in the relevant source files, a statement of the 538additional terms that apply to those files, or a notice indicating 539where to find the applicable terms. 540 541 Additional terms, permissive or non-permissive, may be stated in the 542form of a separately written license, or stated as exceptions; 543the above requirements apply either way. 544 545 8. Termination. 546 547 You may not propagate or modify a covered work except as expressly 548provided under this License. Any attempt otherwise to propagate or 549modify it is void, and will automatically terminate your rights under 550this License (including any patent licenses granted under the third 551paragraph of section 11). 552 553 However, if you cease all violation of this License, then your 554license from a particular copyright holder is reinstated (a) 555provisionally, unless and until the copyright holder explicitly and 556finally terminates your license, and (b) permanently, if the copyright 557holder fails to notify you of the violation by some reasonable means 558prior to 60 days after the cessation. 559 560 Moreover, your license from a particular copyright holder is 561reinstated permanently if the copyright holder notifies you of the 562violation by some reasonable means, this is the first time you have 563received notice of violation of this License (for any work) from that 564copyright holder, and you cure the violation prior to 30 days after 565your receipt of the notice. 566 567 Termination of your rights under this section does not terminate the 568licenses of parties who have received copies or rights from you under 569this License. If your rights have been terminated and not permanently 570reinstated, you do not qualify to receive new licenses for the same 571material under section 10. 572 573 9. Acceptance Not Required for Having Copies. 574 575 You are not required to accept this License in order to receive or 576run a copy of the Program. Ancillary propagation of a covered work 577occurring solely as a consequence of using peer-to-peer transmission 578to receive a copy likewise does not require acceptance. However, 579nothing other than this License grants you permission to propagate or 580modify any covered work. These actions infringe copyright if you do 581not accept this License. Therefore, by modifying or propagating a 582covered work, you indicate your acceptance of this License to do so. 583 584 10. Automatic Licensing of Downstream Recipients. 585 586 Each time you convey a covered work, the recipient automatically 587receives a license from the original licensors, to run, modify and 588propagate that work, subject to this License. You are not responsible 589for enforcing compliance by third parties with this License. 590 591 An "entity transaction" is a transaction transferring control of an 592organization, or substantially all assets of one, or subdividing an 593organization, or merging organizations. If propagation of a covered 594work results from an entity transaction, each party to that 595transaction who receives a copy of the work also receives whatever 596licenses to the work the party's predecessor in interest had or could 597give under the previous paragraph, plus a right to possession of the 598Corresponding Source of the work from the predecessor in interest, if 599the predecessor has it or can get it with reasonable efforts. 600 601 You may not impose any further restrictions on the exercise of the 602rights granted or affirmed under this License. For example, you may 603not impose a license fee, royalty, or other charge for exercise of 604rights granted under this License, and you may not initiate litigation 605(including a cross-claim or counterclaim in a lawsuit) alleging that 606any patent claim is infringed by making, using, selling, offering for 607sale, or importing the Program or any portion of it. 608 609 11. Patents. 610 611 A "contributor" is a copyright holder who authorizes use under this 612License of the Program or a work on which the Program is based. The 613work thus licensed is called the contributor's "contributor version". 614 615 A contributor's "essential patent claims" are all patent claims 616owned or controlled by the contributor, whether already acquired or 617hereafter acquired, that would be infringed by some manner, permitted 618by this License, of making, using, or selling its contributor version, 619but do not include claims that would be infringed only as a 620consequence of further modification of the contributor version. For 621purposes of this definition, "control" includes the right to grant 622patent sublicenses in a manner consistent with the requirements of 623this License. 624 625 Each contributor grants you a non-exclusive, worldwide, royalty-free 626patent license under the contributor's essential patent claims, to 627make, use, sell, offer for sale, import and otherwise run, modify and 628propagate the contents of its contributor version. 629 630 In the following three paragraphs, a "patent license" is any express 631agreement or commitment, however denominated, not to enforce a patent 632(such as an express permission to practice a patent or covenant not to 633sue for patent infringement). To "grant" such a patent license to a 634party means to make such an agreement or commitment not to enforce a 635patent against the party. 636 637 If you convey a covered work, knowingly relying on a patent license, 638and the Corresponding Source of the work is not available for anyone 639to copy, free of charge and under the terms of this License, through a 640publicly available network server or other readily accessible means, 641then you must either (1) cause the Corresponding Source to be so 642available, or (2) arrange to deprive yourself of the benefit of the 643patent license for this particular work, or (3) arrange, in a manner 644consistent with the requirements of this License, to extend the patent 645license to downstream recipients. "Knowingly relying" means you have 646actual knowledge that, but for the patent license, your conveying the 647covered work in a country, or your recipient's use of the covered work 648in a country, would infringe one or more identifiable patents in that 649country that you have reason to believe are valid. 650 651 If, pursuant to or in connection with a single transaction or 652arrangement, you convey, or propagate by procuring conveyance of, a 653covered work, and grant a patent license to some of the parties 654receiving the covered work authorizing them to use, propagate, modify 655or convey a specific copy of the covered work, then the patent license 656you grant is automatically extended to all recipients of the covered 657work and works based on it. 658 659 A patent license is "discriminatory" if it does not include within 660the scope of its coverage, prohibits the exercise of, or is 661conditioned on the non-exercise of one or more of the rights that are 662specifically granted under this License. You may not convey a covered 663work if you are a party to an arrangement with a third party that is 664in the business of distributing software, under which you make payment 665to the third party based on the extent of your activity of conveying 666the work, and under which the third party grants, to any of the 667parties who would receive the covered work from you, a discriminatory 668patent license (a) in connection with copies of the covered work 669conveyed by you (or copies made from those copies), or (b) primarily 670for and in connection with specific products or compilations that 671contain the covered work, unless you entered into that arrangement, 672or that patent license was granted, prior to 28 March 2007. 673 674 Nothing in this License shall be construed as excluding or limiting 675any implied license or other defenses to infringement that may 676otherwise be available to you under applicable patent law. 677 678 12. No Surrender of Others' Freedom. 679 680 If conditions are imposed on you (whether by court order, agreement or 681otherwise) that contradict the conditions of this License, they do not 682excuse you from the conditions of this License. If you cannot convey a 683covered work so as to satisfy simultaneously your obligations under this 684License and any other pertinent obligations, then as a consequence you may 685not convey it at all. For example, if you agree to terms that obligate you 686to collect a royalty for further conveying from those to whom you convey 687the Program, the only way you could satisfy both those terms and this 688License would be to refrain entirely from conveying the Program. 689 690 13. Use with the GNU Affero General Public License. 691 692 Notwithstanding any other provision of this License, you have 693permission to link or combine any covered work with a work licensed 694under version 3 of the GNU Affero General Public License into a single 695combined work, and to convey the resulting work. The terms of this 696License will continue to apply to the part which is the covered work, 697but the special requirements of the GNU Affero General Public License, 698section 13, concerning interaction through a network will apply to the 699combination as such. 700 701 14. Revised Versions of this License. 702 703 The Free Software Foundation may publish revised and/or new versions of 704the GNU General Public License from time to time. Such new versions will 705be similar in spirit to the present version, but may differ in detail to 706address new problems or concerns. 707 708 Each version is given a distinguishing version number. If the 709Program specifies that a certain numbered version of the GNU General 710Public License "or any later version" applies to it, you have the 711option of following the terms and conditions either of that numbered 712version or of any later version published by the Free Software 713Foundation. If the Program does not specify a version number of the 714GNU General Public License, you may choose any version ever published 715by the Free Software Foundation. 716 717 If the Program specifies that a proxy can decide which future 718versions of the GNU General Public License can be used, that proxy's 719public statement of acceptance of a version permanently authorizes you 720to choose that version for the Program. 721 722 Later license versions may give you additional or different 723permissions. However, no additional obligations are imposed on any 724author or copyright holder as a result of your choosing to follow a 725later version. 726 727 15. Disclaimer of Warranty. 728 729 THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY 730APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT 731HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY 732OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, 733THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR 734PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM 735IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF 736ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 737 738 16. Limitation of Liability. 739 740 IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 741WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS 742THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY 743GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE 744USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF 745DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD 746PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), 747EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF 748SUCH DAMAGES. 749 750 17. Interpretation of Sections 15 and 16. 751 752 If the disclaimer of warranty and limitation of liability provided 753above cannot be given local legal effect according to their terms, 754reviewing courts shall apply local law that most closely approximates 755an absolute waiver of all civil liability in connection with the 756Program, unless a warranty or assumption of liability accompanies a 757copy of the Program in return for a fee. 758 759 END OF TERMS AND CONDITIONS 760 761 How to Apply These Terms to Your New Programs 762 763 If you develop a new program, and you want it to be of the greatest 764possible use to the public, the best way to achieve this is to make it 765free software which everyone can redistribute and change under these terms. 766 767 To do so, attach the following notices to the program. It is safest 768to attach them to the start of each source file to most effectively 769state the exclusion of warranty; and each file should have at least 770the "copyright" line and a pointer to where the full notice is found. 771 772 <one line to give the program's name and a brief idea of what it does.> 773 Copyright (C) <year> <name of author> 774 775 This program is free software: you can redistribute it and/or modify 776 it under the terms of the GNU General Public License as published by 777 the Free Software Foundation, either version 3 of the License, or 778 (at your option) any later version. 779 780 This program is distributed in the hope that it will be useful, 781 but WITHOUT ANY WARRANTY; without even the implied warranty of 782 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the 783 GNU General Public License for more details. 784 785 You should have received a copy of the GNU General Public License 786 along with this program. If not, see <http://www.gnu.org/licenses/>. 787 788Also add information on how to contact you by electronic and paper mail. 789 790 If the program does terminal interaction, make it output a short 791notice like this when it starts in an interactive mode: 792 793 <program> Copyright (C) <year> <name of author> 794 This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. 795 This is free software, and you are welcome to redistribute it 796 under certain conditions; type `show c' for details. 797 798The hypothetical commands `show w' and `show c' should show the appropriate 799parts of the General Public License. Of course, your program's commands 800might be different; for a GUI interface, you would use an "about box". 801 802 You should also get your employer (if you work as a programmer) or school, 803if any, to sign a "copyright disclaimer" for the program, if necessary. 804For more information on this, and how to apply and follow the GNU GPL, see 805<http://www.gnu.org/licenses/>. 806 807 The GNU General Public License does not permit incorporating your program 808into proprietary programs. If your program is a subroutine library, you 809may consider it more useful to permit linking proprietary applications with 810the library. If this is what you want to do, use the GNU Lesser General 811Public License instead of this License. But first, please read 812<http://www.gnu.org/philosophy/why-not-lgpl.html>. 813
