r17 r111 1 1 2 GNU GENERAL PUBLIC LICENSE 2 Version 2, June 1991 3 4 Copyright (C) 1989, 1991 Free Software Foundation, Inc. 5 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA 3 Version 3, 29 June 2007 4 5 Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/> 6 6 Everyone is permitted to copy and distribute verbatim copies 7 7 of this license document, but changing it is not allowed. … … 9 9 Preamble 10 10 11 The licenses for most software are designed to take away your 12 freedom to share and change it. By contrast, the GNU General Public 13 License is intended to guarantee your freedom to share and change free 14 software--to make sure the software is free for all its users. This 15 General Public License applies to most of the Free Software 16 Foundation's software and to any other program whose authors commit to 17 using it. (Some other Free Software Foundation software is covered by 18 the GNU Library General Public License instead.) You can apply it to 11 The GNU General Public License is a free, copyleft license for 12 software and other kinds of works. 13 14 The licenses for most software and other practical works are designed 15 to take away your freedom to share and change the works. By contrast, 16 the GNU General Public License is intended to guarantee your freedom to 17 share and change all versions of a program--to make sure it remains free 18 software for all its users. We, the Free Software Foundation, use the 19 GNU General Public License for most of our software; it applies also to 20 any other work released this way by its authors. You can apply it to 19 21 your programs, too. 20 22 … … 22 24 price. Our General Public Licenses are designed to make sure that you 23 25 have the freedom to distribute copies of free software (and charge for 24 th is service if you wish), that you receive source code or can get it25 if you want it, that you can change the software or use pieces of it 26 in new free programs;and that you know you can do these things.27 28 To protect your rights, we need to make restrictions that forbid29 anyone to deny you these rights or to ask you to surrender the rights. 30 These restrictions translate to certain responsibilities for you if you 31 distribute copies of the software, or if you modify it.26 them if you wish), that you receive source code or can get it if you 27 want it, that you can change the software or use pieces of it in new 28 free programs, and that you know you can do these things. 29 30 To protect your rights, we need to prevent others from denying you 31 these rights or asking you to surrender the rights. Therefore, you have 32 certain responsibilities if you distribute copies of the software, or if 33 you modify it: responsibilities to respect the freedom of others. 32 34 33 35 For example, if you distribute copies of such a program, whether 34 gratis or for a fee, you must give the recipients all the rights that 35 you have. You must make sure that they, too, receive or can get the 36 source code. And you must show them these terms so they know their 37 rights. 38 39 We protect your rights with two steps: (1) copyright the software, and 40 (2) offer you this license which gives you legal permission to copy, 41 distribute and/or modify the software. 42 43 Also, for each author's protection and ours, we want to make certain 44 that everyone understands that there is no warranty for this free 45 software. If the software is modified by someone else and passed on, we 46 want its recipients to know that what they have is not the original, so 47 that any problems introduced by others will not reflect on the original 48 authors' reputations. 49 50 Finally, any free program is threatened constantly by software 51 patents. We wish to avoid the danger that redistributors of a free 52 program will individually obtain patent licenses, in effect making the 53 program proprietary. To prevent this, we have made it clear that any 54 patent must be licensed for everyone's free use or not licensed at all. 36 gratis or for a fee, you must pass on to the recipients the same 37 freedoms that you received. You must make sure that they, too, receive 38 or can get the source code. And you must show them these terms so they 39 know their rights. 40 41 Developers that use the GNU GPL protect your rights with two steps: 42 (1) assert copyright on the software, and (2) offer you this License 43 giving you legal permission to copy, distribute and/or modify it. 44 45 For the developers' and authors' protection, the GPL clearly explains 46 that there is no warranty for this free software. For both users' and 47 authors' sake, the GPL requires that modified versions be marked as 48 changed, so that their problems will not be attributed erroneously to 49 authors of previous versions. 50 51 Some devices are designed to deny users access to install or run 52 modified versions of the software inside them, although the manufacturer 53 can do so. This is fundamentally incompatible with the aim of 54 protecting users' freedom to change the software. The systematic 55 pattern of such abuse occurs in the area of products for individuals to 56 use, which is precisely where it is most unacceptable. Therefore, we 57 have designed this version of the GPL to prohibit the practice for those 58 products. If such problems arise substantially in other domains, we 59 stand ready to extend this provision to those domains in future versions 60 of the GPL, as needed to protect the freedom of users. 61 62 Finally, every program is threatened constantly by software patents. 63 States should not allow patents to restrict development and use of 64 software on general-purpose computers, but in those that do, we wish to 65 avoid the special danger that patents applied to a free program could 66 make it effectively proprietary. To prevent this, the GPL assures that 67 patents cannot be used to render the program non-free. 55 68 56 69 The precise terms and conditions for copying, distribution and 57 70 modification follow. 58 71 59 60 GNU GENERAL PUBLIC LICENSE 61 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 62 63 0. This License applies to any program or other work which contains 64 a notice placed by the copyright holder saying it may be distributed 65 under the terms of this General Public License. The "Program", below, 66 refers to any such program or work, and a "work based on the Program" 67 means either the Program or any derivative work under copyright law: 68 that is to say, a work containing the Program or a portion of it, 69 either verbatim or with modifications and/or translated into another 70 language. (Hereinafter, translation is included without limitation in 71 the term "modification".) Each licensee is addressed as "you". 72 73 Activities other than copying, distribution and modification are not 74 covered by this License; they are outside its scope. The act of 75 running the Program is not restricted, and the output from the Program 76 is covered only if its contents constitute a work based on the 77 Program (independent of having been made by running the Program). 78 Whether that is true depends on what the Program does. 79 80 1. You may copy and distribute verbatim copies of the Program's 81 source code as you receive it, in any medium, provided that you 82 conspicuously and appropriately publish on each copy an appropriate 83 copyright notice and disclaimer of warranty; keep intact all the 84 notices that refer to this License and to the absence of any warranty; 85 and give any other recipients of the Program a copy of this License 86 along with the Program. 87 88 You may charge a fee for the physical act of transferring a copy, and 89 you may at your option offer warranty protection in exchange for a fee. 90 91 2. You may modify your copy or copies of the Program or any portion 92 of it, thus forming a work based on the Program, and copy and 93 distribute such modifications or work under the terms of Section 1 94 above, provided that you also meet all of these conditions: 95 96 a) You must cause the modified files to carry prominent notices 97 stating that you changed the files and the date of any change. 98 99 b) You must cause any work that you distribute or publish, that in 100 whole or in part contains or is derived from the Program or any 101 part thereof, to be licensed as a whole at no charge to all third 102 parties under the terms of this License. 103 104 c) If the modified program normally reads commands interactively 105 when run, you must cause it, when started running for such 106 interactive use in the most ordinary way, to print or display an 107 announcement including an appropriate copyright notice and a 108 notice that there is no warranty (or else, saying that you provide 109 a warranty) and that users may redistribute the program under 110 these conditions, and telling the user how to view a copy of this 111 License. (Exception: if the Program itself is interactive but 112 does not normally print such an announcement, your work based on 113 the Program is not required to print an announcement.) 114 115 116 These requirements apply to the modified work as a whole. If 117 identifiable sections of that work are not derived from the Program, 118 and can be reasonably considered independent and separate works in 119 themselves, then this License, and its terms, do not apply to those 120 sections when you distribute them as separate works. But when you 121 distribute the same sections as part of a whole which is a work based 122 on the Program, the distribution of the whole must be on the terms of 123 this License, whose permissions for other licensees extend to the 124 entire whole, and thus to each and every part regardless of who wrote it. 125 126 Thus, it is not the intent of this section to claim rights or contest 127 your rights to work written entirely by you; rather, the intent is to 128 exercise the right to control the distribution of derivative or 129 collective works based on the Program. 130 131 In addition, mere aggregation of another work not based on the Program 132 with the Program (or with a work based on the Program) on a volume of 133 a storage or distribution medium does not bring the other work under 134 the scope of this License. 135 136 3. You may copy and distribute the Program (or a work based on it, 137 under Section 2) in object code or executable form under the terms of 138 Sections 1 and 2 above provided that you also do one of the following: 139 140 a) Accompany it with the complete corresponding machine-readable 141 source code, which must be distributed under the terms of Sections 142 1 and 2 above on a medium customarily used for software interchange; or, 143 144 b) Accompany it with a written offer, valid for at least three 145 years, to give any third party, for a charge no more than your 146 cost of physically performing source distribution, a complete 147 machine-readable copy of the corresponding source code, to be 148 distributed under the terms of Sections 1 and 2 above on a medium 149 customarily used for software interchange; or, 150 151 c) Accompany it with the information you received as to the offer 152 to distribute corresponding source code. (This alternative is 153 allowed only for noncommercial distribution and only if you 154 received the program in object code or executable form with such 155 an offer, in accord with Subsection b above.) 156 157 The source code for a work means the preferred form of the work for 158 making modifications to it. For an executable work, complete source 159 code means all the source code for all modules it contains, plus any 160 associated interface definition files, plus the scripts used to 161 control compilation and installation of the executable. However, as a 162 special exception, the source code distributed need not include 163 anything that is normally distributed (in either source or binary 164 form) with the major components (compiler, kernel, and so on) of the 165 operating system on which the executable runs, unless that component 166 itself accompanies the executable. 167 168 If distribution of executable or object code is made by offering 169 access to copy from a designated place, then offering equivalent 170 access to copy the source code from the same place counts as 171 distribution of the source code, even though third parties are not 172 compelled to copy the source along with the object code. 173 174 175 4. You may not copy, modify, sublicense, or distribute the Program 176 except as expressly provided under this License. Any attempt 177 otherwise to copy, modify, sublicense or distribute the Program is 178 void, and will automatically terminate your rights under this License. 179 However, parties who have received copies, or rights, from you under 180 this License will not have their licenses terminated so long as such 181 parties remain in full compliance. 182 183 5. You are not required to accept this License, since you have not 184 signed it. However, nothing else grants you permission to modify or 185 distribute the Program or its derivative works. These actions are 186 prohibited by law if you do not accept this License. Therefore, by 187 modifying or distributing the Program (or any work based on the 188 Program), you indicate your acceptance of this License to do so, and 189 all its terms and conditions for copying, distributing or modifying 190 the Program or works based on it. 191 192 6. Each time you redistribute the Program (or any work based on the 193 Program), the recipient automatically receives a license from the 194 original licensor to copy, distribute or modify the Program subject to 195 these terms and conditions. You may not impose any further 196 restrictions on the recipients' exercise of the rights granted herein. 197 You are not responsible for enforcing compliance by third parties to 72 TERMS AND CONDITIONS 73 74 0. Definitions. 75 76 "This License" refers to version 3 of the GNU General Public License. 77 78 "Copyright" also means copyright-like laws that apply to other kinds of 79 works, such as semiconductor masks. 80 81 "The Program" refers to any copyrightable work licensed under this 82 License. Each licensee is addressed as "you". "Licensees" and 83 "recipients" may be individuals or organizations. 84 85 To "modify" a work means to copy from or adapt all or part of the work 86 in a fashion requiring copyright permission, other than the making of an 87 exact copy. The resulting work is called a "modified version" of the 88 earlier work or a work "based on" the earlier work. 89 90 A "covered work" means either the unmodified Program or a work based 91 on the Program. 92 93 To "propagate" a work means to do anything with it that, without 94 permission, would make you directly or secondarily liable for 95 infringement under applicable copyright law, except executing it on a 96 computer or modifying a private copy. Propagation includes copying, 97 distribution (with or without modification), making available to the 98 public, and in some countries other activities as well. 99 100 To "convey" a work means any kind of propagation that enables other 101 parties to make or receive copies. Mere interaction with a user through 102 a computer network, with no transfer of a copy, is not conveying. 103 104 An interactive user interface displays "Appropriate Legal Notices" 105 to the extent that it includes a convenient and prominently visible 106 feature that (1) displays an appropriate copyright notice, and (2) 107 tells the user that there is no warranty for the work (except to the 108 extent that warranties are provided), that licensees may convey the 109 work under this License, and how to view a copy of this License. If 110 the interface presents a list of user commands or options, such as a 111 menu, a prominent item in the list meets this criterion. 112 113 1. Source Code. 114 115 The "source code" for a work means the preferred form of the work 116 for making modifications to it. "Object code" means any non-source 117 form of a work. 118 119 A "Standard Interface" means an interface that either is an official 120 standard defined by a recognized standards body, or, in the case of 121 interfaces specified for a particular programming language, one that 122 is widely used among developers working in that language. 123 124 The "System Libraries" of an executable work include anything, other 125 than the work as a whole, that (a) is included in the normal form of 126 packaging a Major Component, but which is not part of that Major 127 Component, and (b) serves only to enable use of the work with that 128 Major Component, or to implement a Standard Interface for which an 129 implementation is available to the public in source code form. A 130 "Major Component", in this context, means a major essential component 131 (kernel, window system, and so on) of the specific operating system 132 (if any) on which the executable work runs, or a compiler used to 133 produce the work, or an object code interpreter used to run it. 134 135 The "Corresponding Source" for a work in object code form means all 136 the source code needed to generate, install, and (for an executable 137 work) run the object code and to modify the work, including scripts to 138 control those activities. However, it does not include the work's 139 System Libraries, or general-purpose tools or generally available free 140 programs which are used unmodified in performing those activities but 141 which are not part of the work. For example, Corresponding Source 142 includes interface definition files associated with source files for 143 the work, and the source code for shared libraries and dynamically 144 linked subprograms that the work is specifically designed to require, 145 such as by intimate data communication or control flow between those 146 subprograms and other parts of the work. 147 148 The Corresponding Source need not include anything that users 149 can regenerate automatically from other parts of the Corresponding 150 Source. 151 152 The Corresponding Source for a work in source code form is that 153 same work. 154 155 2. Basic Permissions. 156 157 All rights granted under this License are granted for the term of 158 copyright on the Program, and are irrevocable provided the stated 159 conditions are met. This License explicitly affirms your unlimited 160 permission to run the unmodified Program. The output from running a 161 covered work is covered by this License only if the output, given its 162 content, constitutes a covered work. This License acknowledges your 163 rights of fair use or other equivalent, as provided by copyright law. 164 165 You may make, run and propagate covered works that you do not 166 convey, without conditions so long as your license otherwise remains 167 in force. You may convey covered works to others for the sole purpose 168 of having them make modifications exclusively for you, or provide you 169 with facilities for running those works, provided that you comply with 170 the terms of this License in conveying all material for which you do 171 not control copyright. Those thus making or running the covered works 172 for you must do so exclusively on your behalf, under your direction 173 and control, on terms that prohibit them from making any copies of 174 your copyrighted material outside their relationship with you. 175 176 Conveying under any other circumstances is permitted solely under 177 the conditions stated below. Sublicensing is not allowed; section 10 178 makes it unnecessary. 179 180 3. Protecting Users' Legal Rights From Anti-Circumvention Law. 181 182 No covered work shall be deemed part of an effective technological 183 measure under any applicable law fulfilling obligations under article 184 11 of the WIPO copyright treaty adopted on 20 December 1996, or 185 similar laws prohibiting or restricting circumvention of such 186 measures. 187 188 When you convey a covered work, you waive any legal power to forbid 189 circumvention of technological measures to the extent such circumvention 190 is effected by exercising rights under this License with respect to 191 the covered work, and you disclaim any intention to limit operation or 192 modification of the work as a means of enforcing, against the work's 193 users, your or third parties' legal rights to forbid circumvention of 194 technological measures. 195 196 4. Conveying Verbatim Copies. 197 198 You may convey verbatim copies of the Program's source code as you 199 receive it, in any medium, provided that you conspicuously and 200 appropriately publish on each copy an appropriate copyright notice; 201 keep intact all notices stating that this License and any 202 non-permissive terms added in accord with section 7 apply to the code; 203 keep intact all notices of the absence of any warranty; and give all 204 recipients a copy of this License along with the Program. 205 206 You may charge any price or no price for each copy that you convey, 207 and you may offer support or warranty protection for a fee. 208 209 5. Conveying Modified Source Versions. 210 211 You may convey a work based on the Program, or the modifications to 212 produce it from the Program, in the form of source code under the 213 terms of section 4, provided that you also meet all of these conditions: 214 215 a) The work must carry prominent notices stating that you modified 216 it, and giving a relevant date. 217 218 b) The work must carry prominent notices stating that it is 219 released under this License and any conditions added under section 220 7. This requirement modifies the requirement in section 4 to 221 "keep intact all notices". 222 223 c) You must license the entire work, as a whole, under this 224 License to anyone who comes into possession of a copy. This 225 License will therefore apply, along with any applicable section 7 226 additional terms, to the whole of the work, and all its parts, 227 regardless of how they are packaged. This License gives no 228 permission to license the work in any other way, but it does not 229 invalidate such permission if you have separately received it. 230 231 d) If the work has interactive user interfaces, each must display 232 Appropriate Legal Notices; however, if the Program has interactive 233 interfaces that do not display Appropriate Legal Notices, your 234 work need not make them do so. 235 236 A compilation of a covered work with other separate and independent 237 works, which are not by their nature extensions of the covered work, 238 and which are not combined with it such as to form a larger program, 239 in or on a volume of a storage or distribution medium, is called an 240 "aggregate" if the compilation and its resulting copyright are not 241 used to limit the access or legal rights of the compilation's users 242 beyond what the individual works permit. Inclusion of a covered work 243 in an aggregate does not cause this License to apply to the other 244 parts of the aggregate. 245 246 6. Conveying Non-Source Forms. 247 248 You may convey a covered work in object code form under the terms 249 of sections 4 and 5, provided that you also convey the 250 machine-readable Corresponding Source under the terms of this License, 251 in one of these ways: 252 253 a) Convey the object code in, or embodied in, a physical product 254 (including a physical distribution medium), accompanied by the 255 Corresponding Source fixed on a durable physical medium 256 customarily used for software interchange. 257 258 b) Convey the object code in, or embodied in, a physical product 259 (including a physical distribution medium), accompanied by a 260 written offer, valid for at least three years and valid for as 261 long as you offer spare parts or customer support for that product 262 model, to give anyone who possesses the object code either (1) a 263 copy of the Corresponding Source for all the software in the 264 product that is covered by this License, on a durable physical 265 medium customarily used for software interchange, for a price no 266 more than your reasonable cost of physically performing this 267 conveying of source, or (2) access to copy the 268 Corresponding Source from a network server at no charge. 269 270 c) Convey individual copies of the object code with a copy of the 271 written offer to provide the Corresponding Source. This 272 alternative is allowed only occasionally and noncommercially, and 273 only if you received the object code with such an offer, in accord 274 with subsection 6b. 275 276 d) Convey the object code by offering access from a designated 277 place (gratis or for a charge), and offer equivalent access to the 278 Corresponding Source in the same way through the same place at no 279 further charge. You need not require recipients to copy the 280 Corresponding Source along with the object code. If the place to 281 copy the object code is a network server, the Corresponding Source 282 may be on a different server (operated by you or a third party) 283 that supports equivalent copying facilities, provided you maintain 284 clear directions next to the object code saying where to find the 285 Corresponding Source. Regardless of what server hosts the 286 Corresponding Source, you remain obligated to ensure that it is 287 available for as long as needed to satisfy these requirements. 288 289 e) Convey the object code using peer-to-peer transmission, provided 290 you inform other peers where the object code and Corresponding 291 Source of the work are being offered to the general public at no 292 charge under subsection 6d. 293 294 A separable portion of the object code, whose source code is excluded 295 from the Corresponding Source as a System Library, need not be 296 included in conveying the object code work. 297 298 A "User Product" is either (1) a "consumer product", which means any 299 tangible personal property which is normally used for personal, family, 300 or household purposes, or (2) anything designed or sold for incorporation 301 into a dwelling. In determining whether a product is a consumer product, 302 doubtful cases shall be resolved in favor of coverage. For a particular 303 product received by a particular user, "normally used" refers to a 304 typical or common use of that class of product, regardless of the status 305 of the particular user or of the way in which the particular user 306 actually uses, or expects or is expected to use, the product. A product 307 is a consumer product regardless of whether the product has substantial 308 commercial, industrial or non-consumer uses, unless such uses represent 309 the only significant mode of use of the product. 310 311 "Installation Information" for a User Product means any methods, 312 procedures, authorization keys, or other information required to install 313 and execute modified versions of a covered work in that User Product from 314 a modified version of its Corresponding Source. The information must 315 suffice to ensure that the continued functioning of the modified object 316 code is in no case prevented or interfered with solely because 317 modification has been made. 318 319 If you convey an object code work under this section in, or with, or 320 specifically for use in, a User Product, and the conveying occurs as 321 part of a transaction in which the right of possession and use of the 322 User Product is transferred to the recipient in perpetuity or for a 323 fixed term (regardless of how the transaction is characterized), the 324 Corresponding Source conveyed under this section must be accompanied 325 by the Installation Information. But this requirement does not apply 326 if neither you nor any third party retains the ability to install 327 modified object code on the User Product (for example, the work has 328 been installed in ROM). 329 330 The requirement to provide Installation Information does not include a 331 requirement to continue to provide support service, warranty, or updates 332 for a work that has been modified or installed by the recipient, or for 333 the User Product in which it has been modified or installed. Access to a 334 network may be denied when the modification itself materially and 335 adversely affects the operation of the network or violates the rules and 336 protocols for communication across the network. 337 338 Corresponding Source conveyed, and Installation Information provided, 339 in accord with this section must be in a format that is publicly 340 documented (and with an implementation available to the public in 341 source code form), and must require no special password or key for 342 unpacking, reading or copying. 343 344 7. Additional Terms. 345 346 "Additional permissions" are terms that supplement the terms of this 347 License by making exceptions from one or more of its conditions. 348 Additional permissions that are applicable to the entire Program shall 349 be treated as though they were included in this License, to the extent 350 that they are valid under applicable law. If additional permissions 351 apply only to part of the Program, that part may be used separately 352 under those permissions, but the entire Program remains governed by 353 this License without regard to the additional permissions. 354 355 When you convey a copy of a covered work, you may at your option 356 remove any additional permissions from that copy, or from any part of 357 it. (Additional permissions may be written to require their own 358 removal in certain cases when you modify the work.) You may place 359 additional permissions on material, added by you to a covered work, 360 for which you have or can give appropriate copyright permission. 361 362 Notwithstanding any other provision of this License, for material you 363 add to a covered work, you may (if authorized by the copyright holders of 364 that material) supplement the terms of this License with terms: 365 366 a) Disclaiming warranty or limiting liability differently from the 367 terms of sections 15 and 16 of this License; or 368 369 b) Requiring preservation of specified reasonable legal notices or 370 author attributions in that material or in the Appropriate Legal 371 Notices displayed by works containing it; or 372 373 c) Prohibiting misrepresentation of the origin of that material, or 374 requiring that modified versions of such material be marked in 375 reasonable ways as different from the original version; or 376 377 d) Limiting the use for publicity purposes of names of licensors or 378 authors of the material; or 379 380 e) Declining to grant rights under trademark law for use of some 381 trade names, trademarks, or service marks; or 382 383 f) Requiring indemnification of licensors and authors of that 384 material by anyone who conveys the material (or modified versions of 385 it) with contractual assumptions of liability to the recipient, for 386 any liability that these contractual assumptions directly impose on 387 those licensors and authors. 388 389 All other non-permissive additional terms are considered "further 390 restrictions" within the meaning of section 10. If the Program as you 391 received it, or any part of it, contains a notice stating that it is 392 governed by this License along with a term that is a further 393 restriction, you may remove that term. If a license document contains 394 a further restriction but permits relicensing or conveying under this 395 License, you may add to a covered work material governed by the terms 396 of that license document, provided that the further restriction does 397 not survive such relicensing or conveying. 398 399 If you add terms to a covered work in accord with this section, you 400 must place, in the relevant source files, a statement of the 401 additional terms that apply to those files, or a notice indicating 402 where to find the applicable terms. 403 404 Additional terms, permissive or non-permissive, may be stated in the 405 form of a separately written license, or stated as exceptions; 406 the above requirements apply either way. 407 408 8. Termination. 409 410 You may not propagate or modify a covered work except as expressly 411 provided under this License. Any attempt otherwise to propagate or 412 modify it is void, and will automatically terminate your rights under 413 this License (including any patent licenses granted under the third 414 paragraph of section 11). 415 416 However, if you cease all violation of this License, then your 417 license from a particular copyright holder is reinstated (a) 418 provisionally, unless and until the copyright holder explicitly and 419 finally terminates your license, and (b) permanently, if the copyright 420 holder fails to notify you of the violation by some reasonable means 421 prior to 60 days after the cessation. 422 423 Moreover, your license from a particular copyright holder is 424 reinstated permanently if the copyright holder notifies you of the 425 violation by some reasonable means, this is the first time you have 426 received notice of violation of this License (for any work) from that 427 copyright holder, and you cure the violation prior to 30 days after 428 your receipt of the notice. 429 430 Termination of your rights under this section does not terminate the 431 licenses of parties who have received copies or rights from you under 432 this License. If your rights have been terminated and not permanently 433 reinstated, you do not qualify to receive new licenses for the same 434 material under section 10. 435 436 9. Acceptance Not Required for Having Copies. 437 438 You are not required to accept this License in order to receive or 439 run a copy of the Program. Ancillary propagation of a covered work 440 occurring solely as a consequence of using peer-to-peer transmission 441 to receive a copy likewise does not require acceptance. However, 442 nothing other than this License grants you permission to propagate or 443 modify any covered work. These actions infringe copyright if you do 444 not accept this License. Therefore, by modifying or propagating a 445 covered work, you indicate your acceptance of this License to do so. 446 447 10. Automatic Licensing of Downstream Recipients. 448 449 Each time you convey a covered work, the recipient automatically 450 receives a license from the original licensors, to run, modify and 451 propagate that work, subject to this License. You are not responsible 452 for enforcing compliance by third parties with this License. 453 454 An "entity transaction" is a transaction transferring control of an 455 organization, or substantially all assets of one, or subdividing an 456 organization, or merging organizations. If propagation of a covered 457 work results from an entity transaction, each party to that 458 transaction who receives a copy of the work also receives whatever 459 licenses to the work the party's predecessor in interest had or could 460 give under the previous paragraph, plus a right to possession of the 461 Corresponding Source of the work from the predecessor in interest, if 462 the predecessor has it or can get it with reasonable efforts. 463 464 You may not impose any further restrictions on the exercise of the 465 rights granted or affirmed under this License. For example, you may 466 not impose a license fee, royalty, or other charge for exercise of 467 rights granted under this License, and you may not initiate litigation 468 (including a cross-claim or counterclaim in a lawsuit) alleging that 469 any patent claim is infringed by making, using, selling, offering for 470 sale, or importing the Program or any portion of it. 471 472 11. Patents. 473 474 A "contributor" is a copyright holder who authorizes use under this 475 License of the Program or a work on which the Program is based. The 476 work thus licensed is called the contributor's "contributor version". 477 478 A contributor's "essential patent claims" are all patent claims 479 owned or controlled by the contributor, whether already acquired or 480 hereafter acquired, that would be infringed by some manner, permitted 481 by this License, of making, using, or selling its contributor version, 482 but do not include claims that would be infringed only as a 483 consequence of further modification of the contributor version. For 484 purposes of this definition, "control" includes the right to grant 485 patent sublicenses in a manner consistent with the requirements of 198 486 this License. 199 487 200 7. If, as a consequence of a court judgment or allegation of patent 201 infringement or for any other reason (not limited to patent issues), 202 conditions are imposed on you (whether by court order, agreement or 488 Each contributor grants you a non-exclusive, worldwide, royalty-free 489 patent license under the contributor's essential patent claims, to 490 make, use, sell, offer for sale, import and otherwise run, modify and 491 propagate the contents of its contributor version. 492 493 In the following three paragraphs, a "patent license" is any express 494 agreement or commitment, however denominated, not to enforce a patent 495 (such as an express permission to practice a patent or covenant not to 496 sue for patent infringement). To "grant" such a patent license to a 497 party means to make such an agreement or commitment not to enforce a 498 patent against the party. 499 500 If you convey a covered work, knowingly relying on a patent license, 501 and the Corresponding Source of the work is not available for anyone 502 to copy, free of charge and under the terms of this License, through a 503 publicly available network server or other readily accessible means, 504 then you must either (1) cause the Corresponding Source to be so 505 available, or (2) arrange to deprive yourself of the benefit of the 506 patent license for this particular work, or (3) arrange, in a manner 507 consistent with the requirements of this License, to extend the patent 508 license to downstream recipients. "Knowingly relying" means you have 509 actual knowledge that, but for the patent license, your conveying the 510 covered work in a country, or your recipient's use of the covered work 511 in a country, would infringe one or more identifiable patents in that 512 country that you have reason to believe are valid. 513 514 If, pursuant to or in connection with a single transaction or 515 arrangement, you convey, or propagate by procuring conveyance of, a 516 covered work, and grant a patent license to some of the parties 517 receiving the covered work authorizing them to use, propagate, modify 518 or convey a specific copy of the covered work, then the patent license 519 you grant is automatically extended to all recipients of the covered 520 work and works based on it. 521 522 A patent license is "discriminatory" if it does not include within 523 the scope of its coverage, prohibits the exercise of, or is 524 conditioned on the non-exercise of one or more of the rights that are 525 specifically granted under this License. You may not convey a covered 526 work if you are a party to an arrangement with a third party that is 527 in the business of distributing software, under which you make payment 528 to the third party based on the extent of your activity of conveying 529 the work, and under which the third party grants, to any of the 530 parties who would receive the covered work from you, a discriminatory 531 patent license (a) in connection with copies of the covered work 532 conveyed by you (or copies made from those copies), or (b) primarily 533 for and in connection with specific products or compilations that 534 contain the covered work, unless you entered into that arrangement, 535 or that patent license was granted, prior to 28 March 2007. 536 537 Nothing in this License shall be construed as excluding or limiting 538 any implied license or other defenses to infringement that may 539 otherwise be available to you under applicable patent law. 540 541 12. No Surrender of Others' Freedom. 542 543 If conditions are imposed on you (whether by court order, agreement or 203 544 otherwise) that contradict the conditions of this License, they do not 204 excuse you from the conditions of this License. If you cannot 205 distribute so as to satisfy simultaneously your obligations under this 206 License and any other pertinent obligations, then as a consequence you 207 may not distribute the Program at all. For example, if a patent 208 license would not permit royalty-free redistribution of the Program by 209 all those who receive copies directly or indirectly through you, then 210 the only way you could satisfy both it and this License would be to 211 refrain entirely from distribution of the Program. 212 213 If any portion of this section is held invalid or unenforceable under 214 any particular circumstance, the balance of the section is intended to 215 apply and the section as a whole is intended to apply in other 216 circumstances. 217 218 It is not the purpose of this section to induce you to infringe any 219 patents or other property right claims or to contest validity of any 220 such claims; this section has the sole purpose of protecting the 221 integrity of the free software distribution system, which is 222 implemented by public license practices. Many people have made 223 generous contributions to the wide range of software distributed 224 through that system in reliance on consistent application of that 225 system; it is up to the author/donor to decide if he or she is willing 226 to distribute software through any other system and a licensee cannot 227 impose that choice. 228 229 This section is intended to make thoroughly clear what is believed to 230 be a consequence of the rest of this License. 231 232 233 8. If the distribution and/or use of the Program is restricted in 234 certain countries either by patents or by copyrighted interfaces, the 235 original copyright holder who places the Program under this License 236 may add an explicit geographical distribution limitation excluding 237 those countries, so that distribution is permitted only in or among 238 countries not thus excluded. In such case, this License incorporates 239 the limitation as if written in the body of this License. 240 241 9. The Free Software Foundation may publish revised and/or new versions 242 of the General Public License from time to time. Such new versions will 545 excuse you from the conditions of this License. If you cannot convey a 546 covered work so as to satisfy simultaneously your obligations under this 547 License and any other pertinent obligations, then as a consequence you may 548 not convey it at all. For example, if you agree to terms that obligate you 549 to collect a royalty for further conveying from those to whom you convey 550 the Program, the only way you could satisfy both those terms and this 551 License would be to refrain entirely from conveying the Program. 552 553 13. Use with the GNU Affero General Public License. 554 555 Notwithstanding any other provision of this License, you have 556 permission to link or combine any covered work with a work licensed 557 under version 3 of the GNU Affero General Public License into a single 558 combined work, and to convey the resulting work. The terms of this 559 License will continue to apply to the part which is the covered work, 560 but the special requirements of the GNU Affero General Public License, 561 section 13, concerning interaction through a network will apply to the 562 combination as such. 563 564 14. Revised Versions of this License. 565 566 The Free Software Foundation may publish revised and/or new versions of 567 the GNU General Public License from time to time. Such new versions will 243 568 be similar in spirit to the present version, but may differ in detail to 244 569 address new problems or concerns. 245 570 246 Each version is given a distinguishing version number. If the Program 247 specifies a version number of this License which applies to it and "any 248 later version", you have the option of following the terms and conditions 249 either of that version or of any later version published by the Free 250 Software Foundation. If the Program does not specify a version number of 251 this License, you may choose any version ever published by the Free Software 252 Foundation. 253 254 10. If you wish to incorporate parts of the Program into other free 255 programs whose distribution conditions are different, write to the author 256 to ask for permission. For software which is copyrighted by the Free 257 Software Foundation, write to the Free Software Foundation; we sometimes 258 make exceptions for this. Our decision will be guided by the two goals 259 of preserving the free status of all derivatives of our free software and 260 of promoting the sharing and reuse of software generally. 261 262 NO WARRANTY 263 264 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY 265 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN 266 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES 267 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED 268 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF 269 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS 270 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE 271 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, 272 REPAIR OR CORRECTION. 273 274 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 275 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR 276 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, 277 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING 278 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED 279 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY 280 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER 281 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE 282 POSSIBILITY OF SUCH DAMAGES. 571 Each version is given a distinguishing version number. If the 572 Program specifies that a certain numbered version of the GNU General 573 Public License "or any later version" applies to it, you have the 574 option of following the terms and conditions either of that numbered 575 version or of any later version published by the Free Software 576 Foundation. If the Program does not specify a version number of the 577 GNU General Public License, you may choose any version ever published 578 by the Free Software Foundation. 579 580 If the Program specifies that a proxy can decide which future 581 versions of the GNU General Public License can be used, that proxy's 582 public statement of acceptance of a version permanently authorizes you 583 to choose that version for the Program. 584 585 Later license versions may give you additional or different 586 permissions. However, no additional obligations are imposed on any 587 author or copyright holder as a result of your choosing to follow a 588 later version. 589 590 15. Disclaimer of Warranty. 591 592 THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY 593 APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT 594 HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY 595 OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, 596 THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR 597 PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM 598 IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF 599 ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 600 601 16. Limitation of Liability. 602 603 IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 604 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS 605 THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY 606 GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE 607 USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF 608 DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD 609 PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), 610 EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF 611 SUCH DAMAGES. 612 613 17. Interpretation of Sections 15 and 16. 614 615 If the disclaimer of warranty and limitation of liability provided 616 above cannot be given local legal effect according to their terms, 617 reviewing courts shall apply local law that most closely approximates 618 an absolute waiver of all civil liability in connection with the 619 Program, unless a warranty or assumption of liability accompanies a 620 copy of the Program in return for a fee. 283 621 284 622 END OF TERMS AND CONDITIONS 623 624 How to Apply These Terms to Your New Programs 625 626 If you develop a new program, and you want it to be of the greatest 627 possible use to the public, the best way to achieve this is to make it 628 free software which everyone can redistribute and change under these terms. 629 630 To do so, attach the following notices to the program. It is safest 631 to attach them to the start of each source file to most effectively 632 state the exclusion of warranty; and each file should have at least 633 the "copyright" line and a pointer to where the full notice is found. 634 635 <one line to give the program's name and a brief idea of what it does.> 636 Copyright (C) <year> <name of author> 637 638 This program is free software: you can redistribute it and/or modify 639 it under the terms of the GNU General Public License as published by 640 the Free Software Foundation, either version 3 of the License, or 641 (at your option) any later version. 642 643 This program is distributed in the hope that it will be useful, 644 but WITHOUT ANY WARRANTY; without even the implied warranty of 645 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the 646 GNU General Public License for more details. 647 648 You should have received a copy of the GNU General Public License 649 along with this program. If not, see <http://www.gnu.org/licenses/>. 650 651 Also add information on how to contact you by electronic and paper mail. 652 653 If the program does terminal interaction, make it output a short 654 notice like this when it starts in an interactive mode: 655 656 <program> Copyright (C) <year> <name of author> 657 This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. 658 This is free software, and you are welcome to redistribute it 659 under certain conditions; type `show c' for details. 660 661 The hypothetical commands `show w' and `show c' should show the appropriate 662 parts of the General Public License. Of course, your program's commands 663 might be different; for a GUI interface, you would use an "about box". 664 665 You should also get your employer (if you work as a programmer) or school, 666 if any, to sign a "copyright disclaimer" for the program, if necessary. 667 For more information on this, and how to apply and follow the GNU GPL, see 668 <http://www.gnu.org/licenses/>. 669 670 The GNU General Public License does not permit incorporating your program 671 into proprietary programs. If your program is a subroutine library, you 672 may consider it more useful to permit linking proprietary applications with 673 the library. If this is what you want to do, use the GNU Lesser General 674 Public License instead of this License. But first, please read 675 <http://www.gnu.org/philosophy/why-not-lgpl.html>. 676
