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

| | 6 | TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION |
| | 7 | |
| | 8 | 1. Definitions. |

| | 20 | direction or management of such entity, whether by contract or |
| | 21 | otherwise, or (ii) ownership of fifty percent (50%) or more of the |
| | 22 | outstanding shares, or (iii) beneficial ownership of such entity. |

| | 29 | source, and configuration files. |
| | 30 | |
| | 31 | "Object" form shall mean any form resulting from mechanical |
| | 32 | transformation or translation of a Source form, including but |
| | 33 | not limited to compiled object code, generated documentation, |
| | 34 | and conversions to other media types. |
| | 35 | |
| | 36 | "Work" shall mean the work of authorship, whether in Source or |
| | 37 | Object form, made available under the License, as indicated by a |
| | 38 | copyright notice that is included in or attached to the work |
| | 39 | (an example is provided in the Appendix below). |
| | 40 | |
| | 41 | "Derivative Works" shall mean any work, whether in Source or Object |
| | 42 | form, that is based on (or derived from) the Work and for which the |
| | 43 | editorial revisions, annotations, elaborations, or other modifications |
| | 44 | represent, as a whole, an original work of authorship. For the purposes |
| | 45 | of this License, Derivative Works shall not include works that remain |
| | 46 | separable from, or merely link (or bind by name) to the interfaces of, |
| | 47 | the Work and Derivative Works thereof. |
| | 48 | |
| | 49 | "Contribution" shall mean any work of authorship, including |
| | 50 | the original version of the Work and any modifications or additions |
| | 51 | to that Work or Derivative Works thereof, that is intentionally |
| | 52 | submitted to Licensor for inclusion in the Work by the copyright owner |
| | 53 | or by an individual or Legal Entity authorized to submit on behalf of |
| | 54 | the copyright owner. For the purposes of this definition, "submitted" |
| | 55 | means any form of electronic, verbal, or written communication sent |
| | 56 | to the Licensor or its representatives, including but not limited to |
| | 57 | communication on electronic mailing lists, source code control systems, |
| | 58 | and issue tracking systems that are managed by, or on behalf of, the |
| | 59 | Licensor for the purpose of discussing and improving the Work, but |
| | 60 | excluding communication that is conspicuously marked or otherwise |
| | 61 | designated in writing by the copyright owner as "Not a Contribution." |
| | 62 | |
| | 63 | "Contributor" shall mean Licensor and any individual or Legal Entity |
| | 64 | on behalf of whom a Contribution has been received by Licensor and |
| | 65 | subsequently incorporated within the Work. |
| | 66 | |
| | 67 | 2. Grant of Copyright License. Subject to the terms and conditions of |
| | 68 | this License, each Contributor hereby grants to You a perpetual, |
| | 69 | worldwide, non-exclusive, no-charge, royalty-free, irrevocable |
| | 70 | copyright license to reproduce, prepare Derivative Works of, |
| | 71 | publicly display, publicly perform, sublicense, and distribute the |
| | 72 | Work and such Derivative Works in Source or Object form. |
| | 73 | |
| | 74 | 3. Grant of Patent License. Subject to the terms and conditions of |
| | 75 | this License, each Contributor hereby grants to You a perpetual, |
| | 76 | worldwide, non-exclusive, no-charge, royalty-free, irrevocable |
| | 77 | (except as stated in this section) patent license to make, have made, |
| | 78 | use, offer to sell, sell, import, and otherwise transfer the Work, |
| | 79 | where such license applies only to those patent claims licensable |
| | 80 | by such Contributor that are necessarily infringed by their |
| | 81 | Contribution(s) alone or by combination of their Contribution(s) |
| | 82 | with the Work to which such Contribution(s) was submitted. If You |
| | 83 | institute patent litigation against any entity (including a |
| | 84 | cross-claim or counterclaim in a lawsuit) alleging that the Work |
| | 85 | or a Contribution incorporated within the Work constitutes direct |
| | 86 | or contributory patent infringement, then any patent licenses |
| | 87 | granted to You under this License for that Work shall terminate |
| | 88 | as of the date such litigation is filed. |
| | 89 | |
| | 90 | 4. Redistribution. You may reproduce and distribute copies of the |
| | 91 | Work or Derivative Works thereof in any medium, with or without |
| | 92 | modifications, and in Source or Object form, provided that You |
| | 93 | meet the following conditions: |
| | 94 | |
| | 95 | (a) You must give any other recipients of the Work or |
| | 96 | Derivative Works a copy of this License; and |
| | 97 | |
| | 98 | (b) You must cause any modified files to carry prominent notices |
| | 99 | stating that You changed the files; and |
| | 100 | |
| | 101 | (c) You must retain, in the Source form of any Derivative Works |
| | 102 | that You distribute, all copyright, patent, trademark, and |
| | 103 | attribution notices from the Source form of the Work, |
| | 104 | excluding those notices that do not pertain to any part of |
| | 105 | the Derivative Works; and |
| | 106 | |
| | 107 | (d) If the Work includes a "NOTICE" text file as part of its |
| | 108 | distribution, then any Derivative Works that You distribute must |
| | 109 | include a readable copy of the attribution notices contained |
| | 110 | within such NOTICE file, excluding those notices that do not |
| | 111 | pertain to any part of the Derivative Works, in at least one |
| | 112 | of the following places: within a NOTICE text file distributed |
| | 113 | as part of the Derivative Works; within the Source form or |
| | 114 | documentation, if provided along with the Derivative Works; or, |
| | 115 | within a display generated by the Derivative Works, if and |
| | 116 | wherever such third-party notices normally appear. The contents |
| | 117 | of the NOTICE file are for informational purposes only and |
| | 118 | do not modify the License. You may add Your own attribution |
| | 119 | notices within Derivative Works that You distribute, alongside |
| | 120 | or as an addendum to the NOTICE text from the Work, provided |
| | 121 | that such additional attribution notices cannot be construed |
| | 122 | as modifying the License. |
| | 123 | |
| | 124 | You may add Your own copyright statement to Your modifications and |
| | 125 | may provide additional or different license terms and conditions |
| | 126 | for use, reproduction, or distribution of Your modifications, or |
| | 127 | for any such Derivative Works as a whole, provided Your use, |
| | 128 | reproduction, and distribution of the Work otherwise complies with |
| | 129 | the conditions stated in this License. |
| | 130 | |
| | 131 | 5. Submission of Contributions. Unless You explicitly state otherwise, |
| | 132 | any Contribution intentionally submitted for inclusion in the Work |
| | 133 | by You to the Licensor shall be under the terms and conditions of |
| | 134 | this License, without any additional terms or conditions. |
| | 135 | Notwithstanding the above, nothing herein shall supersede or modify |
| | 136 | the terms of any separate license agreement you may have executed |
| | 137 | with Licensor regarding such Contributions. |
| | 138 | |
| | 139 | 6. Trademarks. This License does not grant permission to use the trade |
| | 140 | names, trademarks, service marks, or product names of the Licensor, |
| | 141 | except as required for reasonable and customary use in describing the |
| | 142 | origin of the Work and reproducing the content of the NOTICE file. |
| | 143 | |
| | 144 | 7. Disclaimer of Warranty. Unless required by applicable law or |
| | 145 | agreed to in writing, Licensor provides the Work (and each |
| | 146 | Contributor provides its Contributions) on an "AS IS" BASIS, |
| | 147 | WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or |
| | 148 | implied, including, without limitation, any warranties or conditions |
| | 149 | of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A |
| | 150 | PARTICULAR PURPOSE. You are solely responsible for determining the |
| | 151 | appropriateness of using or redistributing the Work and assume any |
| | 152 | risks associated with Your exercise of permissions under this License. |
| | 153 | |
| | 154 | 8. Limitation of Liability. In no event and under no legal theory, |
| | 155 | whether in tort (including negligence), contract, or otherwise, |
