| 3 | Version 3, 29 June 2007 |
---|
| 4 | |
---|
| 5 | Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/> |
---|
| 6 | Everyone is permitted to copy and distribute verbatim copies |
---|
| 7 | of this license document, but changing it is not allowed. |
---|
| 8 | |
---|
| 9 | Preamble |
---|
| 10 | |
---|
| 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 |
---|
| 21 | your programs, too. |
---|
| 22 | |
---|
| 23 | When we speak of free software, we are referring to freedom, not |
---|
| 24 | price. Our General Public Licenses are designed to make sure that you |
---|
| 25 | have the freedom to distribute copies of free software (and charge for |
---|
| 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. |
---|
| 34 | |
---|
| 35 | For example, if you distribute copies of such a program, whether |
---|
| 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. |
---|
| 68 | |
---|
| 69 | The precise terms and conditions for copying, distribution and |
---|
| 70 | modification follow. |
---|
| 71 | |
---|
| 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 |
---|
| 486 | this License. |
---|
| 487 | |
---|
| 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 |
---|
| 544 | otherwise) that contradict the conditions of this License, they do not |
---|
| 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 |
---|
| 568 | be similar in spirit to the present version, but may differ in detail to |
---|
| 569 | address new problems or concerns. |
---|
| 570 | |
---|
| 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. |
---|
| 621 | |
---|
| 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> |

| 644 | but WITHOUT ANY WARRANTY; without even the implied warranty of |

---|

---|
| 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. |
---|

---|
| 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 |
---|
