| 59 | | GNU GENERAL PUBLIC LICENSE |
| 60 | | TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION |
| 61 | | |
| 62 | | 0. This License applies to any program or other work which contains |
| 63 | | a notice placed by the copyright holder saying it may be distributed |
| 64 | | under the terms of this General Public License. The "Program", below, |
| 65 | | refers to any such program or work, and a "work based on the Program" |
| 66 | | means either the Program or any derivative work under copyright law: |
| 67 | | that is to say, a work containing the Program or a portion of it, |
| 68 | | either verbatim or with modifications and/or translated into another |
| 69 | | language. (Hereinafter, translation is included without limitation in |
| 70 | | the term "modification".) Each licensee is addressed as "you". |
| 71 | | |
| 72 | | Activities other than copying, distribution and modification are not |
| 73 | | covered by this License; they are outside its scope. The act of |
| 74 | | running the Program is not restricted, and the output from the Program |
| 75 | | is covered only if its contents constitute a work based on the |
| 76 | | Program (independent of having been made by running the Program). |
| 77 | | Whether that is true depends on what the Program does. |
| 78 | | |
| 79 | | 1. You may copy and distribute verbatim copies of the Program's |
| 80 | | source code as you receive it, in any medium, provided that you |
| 81 | | conspicuously and appropriately publish on each copy an appropriate |
| 82 | | copyright notice and disclaimer of warranty; keep intact all the |
| 83 | | notices that refer to this License and to the absence of any warranty; |
| 84 | | and give any other recipients of the Program a copy of this License |
| 85 | | along with the Program. |
| 86 | | |
| 87 | | You may charge a fee for the physical act of transferring a copy, and |
| 88 | | you may at your option offer warranty protection in exchange for a fee. |
| 89 | | |
| 90 | | 2. You may modify your copy or copies of the Program or any portion |
| 91 | | of it, thus forming a work based on the Program, and copy and |
| 92 | | distribute such modifications or work under the terms of Section 1 |
| 93 | | above, provided that you also meet all of these conditions: |
| 94 | | |
| 95 | | a) You must cause the modified files to carry prominent notices |
| 96 | | stating that you changed the files and the date of any change. |
| 97 | | |
| 98 | | b) You must cause any work that you distribute or publish, that in |
| 99 | | whole or in part contains or is derived from the Program or any |
| 100 | | part thereof, to be licensed as a whole at no charge to all third |
| 101 | | parties under the terms of this License. |
| 102 | | |
| 103 | | c) If the modified program normally reads commands interactively |
| 104 | | when run, you must cause it, when started running for such |
| 105 | | interactive use in the most ordinary way, to print or display an |
| 106 | | announcement including an appropriate copyright notice and a |
| 107 | | notice that there is no warranty (or else, saying that you provide |
| 108 | | a warranty) and that users may redistribute the program under |
| 109 | | these conditions, and telling the user how to view a copy of this |
| 110 | | License. (Exception: if the Program itself is interactive but |
| 111 | | does not normally print such an announcement, your work based on |
| 112 | | the Program is not required to print an announcement.) |
| 113 | | |
| 114 | | These requirements apply to the modified work as a whole. If |
| 115 | | identifiable sections of that work are not derived from the Program, |
| 116 | | and can be reasonably considered independent and separate works in |
| 117 | | themselves, then this License, and its terms, do not apply to those |
| 118 | | sections when you distribute them as separate works. But when you |
| 119 | | distribute the same sections as part of a whole which is a work based |
| 120 | | on the Program, the distribution of the whole must be on the terms of |
| 121 | | this License, whose permissions for other licensees extend to the |
| 122 | | entire whole, and thus to each and every part regardless of who wrote it. |
| 123 | | |
| 124 | | Thus, it is not the intent of this section to claim rights or contest |
| 125 | | your rights to work written entirely by you; rather, the intent is to |
| 126 | | exercise the right to control the distribution of derivative or |
| 127 | | collective works based on the Program. |
| 128 | | |
| 129 | | In addition, mere aggregation of another work not based on the Program |
| 130 | | with the Program (or with a work based on the Program) on a volume of |
| 131 | | a storage or distribution medium does not bring the other work under |
| 132 | | the scope of this License. |
| 133 | | |
| 134 | | 3. You may copy and distribute the Program (or a work based on it, |
| 135 | | under Section 2) in object code or executable form under the terms of |
| 136 | | Sections 1 and 2 above provided that you also do one of the following: |
| 137 | | |
| 138 | | a) Accompany it with the complete corresponding machine-readable |
| 139 | | source code, which must be distributed under the terms of Sections |
| 140 | | 1 and 2 above on a medium customarily used for software interchange; or, |
| 141 | | |
| 142 | | b) Accompany it with a written offer, valid for at least three |
| 143 | | years, to give any third party, for a charge no more than your |
| 144 | | cost of physically performing source distribution, a complete |
| 145 | | machine-readable copy of the corresponding source code, to be |
| 146 | | distributed under the terms of Sections 1 and 2 above on a medium |
| 147 | | customarily used for software interchange; or, |
| 148 | | |
| 149 | | c) Accompany it with the information you received as to the offer |
| 150 | | to distribute corresponding source code. (This alternative is |
| 151 | | allowed only for noncommercial distribution and only if you |
| 152 | | received the program in object code or executable form with such |
| 153 | | an offer, in accord with Subsection b above.) |
| 154 | | |
| 155 | | The source code for a work means the preferred form of the work for |
| 156 | | making modifications to it. For an executable work, complete source |
| 157 | | code means all the source code for all modules it contains, plus any |
| 158 | | associated interface definition files, plus the scripts used to |
| 159 | | control compilation and installation of the executable. However, as a |
| 160 | | special exception, the source code distributed need not include |
| 161 | | anything that is normally distributed (in either source or binary |
| 162 | | form) with the major components (compiler, kernel, and so on) of the |
| 163 | | operating system on which the executable runs, unless that component |
| 164 | | itself accompanies the executable. |
| 165 | | |
| 166 | | If distribution of executable or object code is made by offering |
| 167 | | access to copy from a designated place, then offering equivalent |
| 168 | | access to copy the source code from the same place counts as |
| 169 | | distribution of the source code, even though third parties are not |
| 170 | | compelled to copy the source along with the object code. |
| 171 | | |
| 172 | | 4. You may not copy, modify, sublicense, or distribute the Program |
| 173 | | except as expressly provided under this License. Any attempt |
| 174 | | otherwise to copy, modify, sublicense or distribute the Program is |
| 175 | | void, and will automatically terminate your rights under this License. |
| 176 | | However, parties who have received copies, or rights, from you under |
| 177 | | this License will not have their licenses terminated so long as such |
| 178 | | parties remain in full compliance. |
| 179 | | |
| 180 | | 5. You are not required to accept this License, since you have not |
| 181 | | signed it. However, nothing else grants you permission to modify or |
| 182 | | distribute the Program or its derivative works. These actions are |
| 183 | | prohibited by law if you do not accept this License. Therefore, by |
| 184 | | modifying or distributing the Program (or any work based on the |
| 185 | | Program), you indicate your acceptance of this License to do so, and |
| 186 | | all its terms and conditions for copying, distributing or modifying |
| 187 | | the Program or works based on it. |
| 188 | | |
| 189 | | 6. Each time you redistribute the Program (or any work based on the |
| 190 | | Program), the recipient automatically receives a license from the |
| 191 | | original licensor to copy, distribute or modify the Program subject to |
| 192 | | these terms and conditions. You may not impose any further |
| 193 | | restrictions on the recipients' exercise of the rights granted herein. |
| 194 | | You are not responsible for enforcing compliance by third parties to |
| | 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 |
