You may copy and distribute verbatim copies of the Program's 96 96 - source code as you receive it, in any medium, provided that you 97 97 - conspicuously and appropriately publish on each copy an appropriate 98 98 - copyright notice and disclaimer of warranty; keep intact all the 99 99 - notices that refer to this License and to the absence of any warranty; 100 100 - and give any other recipients of the Program a copy of this License 101 101 - along with the Program. 102 102 - 103 103 - You may charge a fee for the physical act of transferring a copy, and 104 104 - you may at your option offer warranty protection in exchange for a fee. 105 105 - 106 106 - 2. You may modify your copy or copies of the Program or any portion 107 107 - of it, thus forming a work based on the Program, and copy and 108 108 - distribute such modifications or work under the terms of Section 1 109 109 - above, provided that you also meet all of these conditions: 110 110 - 111 111 - a) You must cause the modified files to carry prominent notices 112 112 - stating that you changed the files and the date of any change. 113 113 - 114 114 - b) You must cause any work that you distribute or publish, that in 115 115 - whole or in part contains or is derived from the Program or any 116 116 - part thereof, to be licensed as a whole at no charge to all third 117 117 - parties under the terms of this License. 118 118 - 119 119 - c) If the modified program normally reads commands interactively 120 120 - when run, you must cause it, when started running for such 121 121 - interactive use in the most ordinary way, to print or display an 122 122 - announcement including an appropriate copyright notice and a 123 123 - notice that there is no warranty (or else, saying that you provide 124 124 - a warranty) and that users may redistribute the program under 125 125 - these conditions, and telling the user how to view a copy of this 126 126 - License. (Exception: if the Program itself is interactive but 127 127 - does not normally print such an announcement, your work based on 128 128 - the Program is not required to print an announcement.) 129 129 -  130 130 - These requirements apply to the modified work as a whole. If 131 131 - identifiable sections of that work are not derived from the Program, 132 132 - and can be reasonably considered independent and separate works in 133 133 - themselves, then this License, and its terms, do not apply to those 134 134 - sections when you distribute them as separate works. But when you 135 135 - distribute the same sections as part of a whole which is a work based 136 136 - on the Program, the distribution of the whole must be on the terms of 137 137 - this License, whose permissions for other licensees extend to the 138 138 - entire whole, and thus to each and every part regardless of who wrote it. 139 139 - 140 140 - Thus, it is not the intent of this section to claim rights or contest 141 141 - your rights to work written entirely by you; rather, the intent is to 142 142 - exercise the right to control the distribution of derivative or 143 143 - collective works based on the Program. 144 144 - 145 145 - In addition, mere aggregation of another work not based on the Program 146 146 - with the Program (or with a work based on the Program) on a volume of 147 147 - a storage or distribution medium does not bring the other work under 148 148 - the scope of this License. 149 149 - 150 150 - 3. You may copy and distribute the Program (or a work based on it, 151 151 - under Section 2) in object code or executable form under the terms of 152 152 - Sections 1 and 2 above provided that you also do one of the following: 153 153 - 154 154 - a) Accompany it with the complete corresponding machine-readable 155 155 - source code, which must be distributed under the terms of Sections 156 156 - 1 and 2 above on a medium customarily used for software interchange; or, 157 157 - 158 158 - b) Accompany it with a written offer, valid for at least three 159 159 - years, to give any third party, for a charge no more than your 160 160 - cost of physically performing source distribution, a complete 161 161 - machine-readable copy of the corresponding source code, to be 162 162 - distributed under the terms of Sections 1 and 2 above on a medium 163 163 - customarily used for software interchange; or, 164 164 - 165 165 - c) Accompany it with the information you received as to the offer 166 166 - to distribute corresponding source code. (This alternative is 167 167 - allowed only for noncommercial distribution and only if you 168 168 - received the program in object code or executable form with such 169 169 - an offer, in accord with Subsection b above.) 170 170 - 171 171 - The source code for a work means the preferred form of the work for 172 172 - making modifications to it. For an executable work, complete source 173 173 - code means all the source code for all modules it contains, plus any 174 174 - associated interface definition files, plus the scripts used to 175 175 - control compilation and installation of the executable. However, as a 176 176 - special exception, the source code distributed need not include 177 177 - anything that is normally distributed (in either source or binary 178 178 - form) with the major components (compiler, kernel, and so on) of the 179 179 - operating system on which the executable runs, unless that component 180 180 - itself accompanies the executable. 1 1 + The Linux Kernel is provided under: 181 2 182 182 - If distribution of executable or object code is made by offering 183 183 - access to copy from a designated place, then offering equivalent 184 184 - access to copy the source code from the same place counts as 185 185 - distribution of the source code, even though third parties are not 186 186 - compelled to copy the source along with the object code. 187 187 -  188 188 - 4. You may not copy, modify, sublicense, or distribute the Program 189 189 - except as expressly provided under this License. Any attempt 190 190 - otherwise to copy, modify, sublicense or distribute the Program is 191 191 - void, and will automatically terminate your rights under this License. 192 192 - However, parties who have received copies, or rights, from you under 193 193 - this License will not have their licenses terminated so long as such 194 194 - parties remain in full compliance. 3 3 + SPDX-License-Identifier: GPL-2.0 WITH Linux-syscall-note 195 4 196 196 - 5. You are not required to accept this License, since you have not 197 197 - signed it. However, nothing else grants you permission to modify or 198 198 - distribute the Program or its derivative works. These actions are 199 199 - prohibited by law if you do not accept this License. Therefore, by 200 200 - modifying or distributing the Program (or any work based on the 201 201 - Program), you indicate your acceptance of this License to do so, and 202 202 - all its terms and conditions for copying, distributing or modifying 203 203 - the Program or works based on it. 204 204 - 205 205 - 6. Each time you redistribute the Program (or any work based on the 206 206 - Program), the recipient automatically receives a license from the 207 207 - original licensor to copy, distribute or modify the Program subject to 208 208 - these terms and conditions. You may not impose any further 209 209 - restrictions on the recipients' exercise of the rights granted herein. 210 210 - You are not responsible for enforcing compliance by third parties to 211 211 - this License. 212 212 - 213 213 - 7. If, as a consequence of a court judgment or allegation of patent 214 214 - infringement or for any other reason (not limited to patent issues), 215 215 - conditions are imposed on you (whether by court order, agreement or 216 216 - otherwise) that contradict the conditions of this License, they do not 217 217 - excuse you from the conditions of this License. If you cannot 218 218 - distribute so as to satisfy simultaneously your obligations under this 219 219 - License and any other pertinent obligations, then as a consequence you 220 220 - may not distribute the Program at all. For example, if a patent 221 221 - license would not permit royalty-free redistribution of the Program by 222 222 - all those who receive copies directly or indirectly through you, then 223 223 - the only way you could satisfy both it and this License would be to 224 224 - refrain entirely from distribution of the Program. 5 5 + Being under the terms of the GNU General Public License version 2 only, 6 6 + according with: 225 7 226 226 - If any portion of this section is held invalid or unenforceable under 227 227 - any particular circumstance, the balance of the section is intended to 228 228 - apply and the section as a whole is intended to apply in other 229 229 - circumstances. 8 8 + LICENSES/preferred/GPL-2.0 230 9 231 231 - It is not the purpose of this section to induce you to infringe any 232 232 - patents or other property right claims or to contest validity of any 233 233 - such claims; this section has the sole purpose of protecting the 234 234 - integrity of the free software distribution system, which is 235 235 - implemented by public license practices. Many people have made 236 236 - generous contributions to the wide range of software distributed 237 237 - through that system in reliance on consistent application of that 238 238 - system; it is up to the author/donor to decide if he or she is willing 239 239 - to distribute software through any other system and a licensee cannot 240 240 - impose that choice. 10 10 + With an explicit syscall exception, as stated at: 241 11 242 242 - This section is intended to make thoroughly clear what is believed to 243 243 - be a consequence of the rest of this License. 244 244 -  245 245 - 8. If the distribution and/or use of the Program is restricted in 246 246 - certain countries either by patents or by copyrighted interfaces, the 247 247 - original copyright holder who places the Program under this License 248 248 - may add an explicit geographical distribution limitation excluding 249 249 - those countries, so that distribution is permitted only in or among 250 250 - countries not thus excluded. In such case, this License incorporates 251 251 - the limitation as if written in the body of this License. 12 12 + LICENSES/exceptions/Linux-syscall-note 252 13 253 253 - 9. The Free Software Foundation may publish revised and/or new versions 254 254 - of the General Public License from time to time. Such new versions will 255 255 - be similar in spirit to the present version, but may differ in detail to 256 256 - address new problems or concerns. 14 14 + In addition, other licenses may also apply. Please see: 257 15 258 258 - Each version is given a distinguishing version number. If the Program 259 259 - specifies a version number of this License which applies to it and "any 260 260 - later version", you have the option of following the terms and conditions 261 261 - either of that version or of any later version published by the Free 262 262 - Software Foundation. If the Program does not specify a version number of 263 263 - this License, you may choose any version ever published by the Free Software 264 264 - Foundation. 16 16 + Documentation/process/license-rules.rst 265 17 266 266 - 10. If you wish to incorporate parts of the Program into other free 267 267 - programs whose distribution conditions are different, write to the author 268 268 - to ask for permission. For software which is copyrighted by the Free 269 269 - Software Foundation, write to the Free Software Foundation; we sometimes 270 270 - make exceptions for this. Our decision will be guided by the two goals 271 271 - of preserving the free status of all derivatives of our free software and 272 272 - of promoting the sharing and reuse of software generally. 273 273 - 274 274 - NO WARRANTY 275 275 - 276 276 - 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY 277 277 - FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN 278 278 - OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES 279 279 - PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED 280 280 - OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF 281 281 - MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS 282 282 - TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE 283 283 - PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, 284 284 - REPAIR OR CORRECTION. 285 285 - 286 286 - 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 287 287 - WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR 288 288 - REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, 289 289 - INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING 290 290 - OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED 291 291 - TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY 292 292 - YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER 293 293 - PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE 294 294 - POSSIBILITY OF SUCH DAMAGES. 295 295 - 296 296 - END OF TERMS AND CONDITIONS 297 297 -  298 298 - How to Apply These Terms to Your New Programs 299 299 - 300 300 - If you develop a new program, and you want it to be of the greatest 301 301 - possible use to the public, the best way to achieve this is to make it 302 302 - free software which everyone can redistribute and change under these terms. 303 303 - 304 304 - To do so, attach the following notices to the program. It is safest 305 305 - to attach them to the start of each source file to most effectively 306 306 - convey the exclusion of warranty; and each file should have at least 307 307 - the "copyright" line and a pointer to where the full notice is found. 308 308 - 309 309 - <one line to give the program's name and a brief idea of what it does.> 310 310 - Copyright (C) <year> <name of author> 311 311 - 312 312 - This program is free software; you can redistribute it and/or modify 313 313 - it under the terms of the GNU General Public License as published by 314 314 - the Free Software Foundation; either version 2 of the License, or 315 315 - (at your option) any later version. 316 316 - 317 317 - This program is distributed in the hope that it will be useful, 318 318 - but WITHOUT ANY WARRANTY; without even the implied warranty of 319 319 - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the 320 320 - GNU General Public License for more details. 321 321 - 322 322 - You should have received a copy of the GNU General Public License 323 323 - along with this program; if not, write to the Free Software 324 324 - Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA 325 325 - 326 326 - 327 327 - Also add information on how to contact you by electronic and paper mail. 328 328 - 329 329 - If the program is interactive, make it output a short notice like this 330 330 - when it starts in an interactive mode: 331 331 - 332 332 - Gnomovision version 69, Copyright (C) year name of author 333 333 - Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. 334 334 - This is free software, and you are welcome to redistribute it 335 335 - under certain conditions; type `show c' for details. 336 336 - 337 337 - The hypothetical commands `show w' and `show c' should show the appropriate 338 338 - parts of the General Public License. Of course, the commands you use may 339 339 - be called something other than `show w' and `show c'; they could even be 340 340 - mouse-clicks or menu items--whatever suits your program. 341 341 - 342 342 - You should also get your employer (if you work as a programmer) or your 343 343 - school, if any, to sign a "copyright disclaimer" for the program, if 344 344 - necessary. Here is a sample; alter the names: 345 345 - 346 346 - Yoyodyne, Inc., hereby disclaims all copyright interest in the program 347 347 - `Gnomovision' (which makes passes at compilers) written by James Hacker. 348 348 - 349 349 - <signature of Ty Coon>, 1 April 1989 350 350 - Ty Coon, President of Vice 351 351 - 352 352 - This General Public License does not permit incorporating your program into 353 353 - proprietary programs. If your program is a subroutine library, you may 354 354 - consider it more useful to permit linking proprietary applications with the 355 355 - library. If this is what you want to do, use the GNU Library General 356 356 - Public License instead of this License. 18 18 + for more details.

You must make sure that they, too, receive or can get the 49 49 + source code. And you must show them these terms so they know their 50 50 + rights. 51 51 + 52 52 + We protect your rights with two steps: (1) copyright the software, and 53 53 + (2) offer you this license which gives you legal permission to copy, 54 54 + distribute and/or modify the software. 55 55 + 56 56 + Also, for each author's protection and ours, we want to make certain 57 57 + that everyone understands that there is no warranty for this free 58 58 + software. If the software is modified by someone else and passed on, we 59 59 + want its recipients to know that what they have is not the original, so 60 60 + that any problems introduced by others will not reflect on the original 61 61 + authors' reputations. 62 62 + 63 63 + Finally, any free program is threatened constantly by software 64 64 + patents. We wish to avoid the danger that redistributors of a free 65 65 + program will individually obtain patent licenses, in effect making the 66 66 + program proprietary. To prevent this, we have made it clear that any 67 67 + patent must be licensed for everyone's free use or not licensed at all. 68 68 + 69 69 + The precise terms and conditions for copying, distribution and 70 70 + modification follow. 71 71 +  72 72 + GNU GENERAL PUBLIC LICENSE 73 73 + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 74 74 + 75 75 + 0. This License applies to any program or other work which contains 76 76 + a notice placed by the copyright holder saying it may be distributed 77 77 + under the terms of this General Public License. The "Program", below, 78 78 + refers to any such program or work, and a "work based on the Program" 79 79 + means either the Program or any derivative work under copyright law: 80 80 + that is to say, a work containing the Program or a portion of it, 81 81 + either verbatim or with modifications and/or translated into another 82 82 + language. (Hereinafter, translation is included without limitation in 83 83 + the term "modification".) Each licensee is addressed as "you". 84 84 + 85 85 + Activities other than copying, distribution and modification are not 86 86 + covered by this License; they are outside its scope. The act of 87 87 + running the Program is not restricted, and the output from the Program 88 88 + is covered only if its contents constitute a work based on the 89 89 + Program (independent of having been made by running the Program). 90 90 + Whether that is true depends on what the Program does. 91 91 + 92 92 + 1. You may copy and distribute verbatim copies of the Program's 93 93 + source code as you receive it, in any medium, provided that you 94 94 + conspicuously and appropriately publish on each copy an appropriate 95 95 + copyright notice and disclaimer of warranty; keep intact all the 96 96 + notices that refer to this License and to the absence of any warranty; 97 97 + and give any other recipients of the Program a copy of this License 98 98 + along with the Program. 99 99 + 100 100 + You may charge a fee for the physical act of transferring a copy, and 101 101 + you may at your option offer warranty protection in exchange for a fee. 102 102 + 103 103 + 2. You may modify your copy or copies of the Program or any portion 104 104 + of it, thus forming a work based on the Program, and copy and 105 105 + distribute such modifications or work under the terms of Section 1 106 106 + above, provided that you also meet all of these conditions: 107 107 + 108 108 + a) You must cause the modified files to carry prominent notices 109 109 + stating that you changed the files and the date of any change. 110 110 + 111 111 + b) You must cause any work that you distribute or publish, that in 112 112 + whole or in part contains or is derived from the Program or any 113 113 + part thereof, to be licensed as a whole at no charge to all third 114 114 + parties under the terms of this License. 115 115 + 116 116 + c) If the modified program normally reads commands interactively 117 117 + when run, you must cause it, when started running for such 118 118 + interactive use in the most ordinary way, to print or display an 119 119 + announcement including an appropriate copyright notice and a 120 120 + notice that there is no warranty (or else, saying that you provide 121 121 + a warranty) and that users may redistribute the program under 122 122 + these conditions, and telling the user how to view a copy of this 123 123 + License. (Exception: if the Program itself is interactive but 124 124 + does not normally print such an announcement, your work based on 125 125 + the Program is not required to print an announcement.) 126 126 +  127 127 + These requirements apply to the modified work as a whole. If 128 128 + identifiable sections of that work are not derived from the Program, 129 129 + and can be reasonably considered independent and separate works in 130 130 + themselves, then this License, and its terms, do not apply to those 131 131 + sections when you distribute them as separate works. But when you 132 132 + distribute the same sections as part of a whole which is a work based 133 133 + on the Program, the distribution of the whole must be on the terms of 134 134 + this License, whose permissions for other licensees extend to the 135 135 + entire whole, and thus to each and every part regardless of who wrote it. 136 136 + 137 137 + Thus, it is not the intent of this section to claim rights or contest 138 138 + your rights to work written entirely by you; rather, the intent is to 139 139 + exercise the right to control the distribution of derivative or 140 140 + collective works based on the Program. 141 141 + 142 142 + In addition, mere aggregation of another work not based on the Program 143 143 + with the Program (or with a work based on the Program) on a volume of 144 144 + a storage or distribution medium does not bring the other work under 145 145 + the scope of this License. 146 146 + 147 147 + 3. You may copy and distribute the Program (or a work based on it, 148 148 + under Section 2) in object code or executable form under the terms of 149 149 + Sections 1 and 2 above provided that you also do one of the following: 150 150 + 151 151 + a) Accompany it with the complete corresponding machine-readable 152 152 + source code, which must be distributed under the terms of Sections 153 153 + 1 and 2 above on a medium customarily used for software interchange; or, 154 154 + 155 155 + b) Accompany it with a written offer, valid for at least three 156 156 + years, to give any third party, for a charge no more than your 157 157 + cost of physically performing source distribution, a complete 158 158 + machine-readable copy of the corresponding source code, to be 159 159 + distributed under the terms of Sections 1 and 2 above on a medium 160 160 + customarily used for software interchange; or, 161 161 + 162 162 + c) Accompany it with the information you received as to the offer 163 163 + to distribute corresponding source code. (This alternative is 164 164 + allowed only for noncommercial distribution and only if you 165 165 + received the program in object code or executable form with such 166 166 + an offer, in accord with Subsection b above.) 167 167 + 168 168 + The source code for a work means the preferred form of the work for 169 169 + making modifications to it. For an executable work, complete source 170 170 + code means all the source code for all modules it contains, plus any 171 171 + associated interface definition files, plus the scripts used to 172 172 + control compilation and installation of the executable. However, as a 173 173 + special exception, the source code distributed need not include 174 174 + anything that is normally distributed (in either source or binary 175 175 + form) with the major components (compiler, kernel, and so on) of the 176 176 + operating system on which the executable runs, unless that component 177 177 + itself accompanies the executable. 178 178 + 179 179 + If distribution of executable or object code is made by offering 180 180 + access to copy from a designated place, then offering equivalent 181 181 + access to copy the source code from the same place counts as 182 182 + distribution of the source code, even though third parties are not 183 183 + compelled to copy the source along with the object code. 184 184 +  185 185 + 4. You may not copy, modify, sublicense, or distribute the Program 186 186 + except as expressly provided under this License. Any attempt 187 187 + otherwise to copy, modify, sublicense or distribute the Program is 188 188 + void, and will automatically terminate your rights under this License. 189 189 + However, parties who have received copies, or rights, from you under 190 190 + this License will not have their licenses terminated so long as such 191 191 + parties remain in full compliance. 192 192 + 193 193 + 5. You are not required to accept this License, since you have not 194 194 + signed it. However, nothing else grants you permission to modify or 195 195 + distribute the Program or its derivative works. These actions are 196 196 + prohibited by law if you do not accept this License. Therefore, by 197 197 + modifying or distributing the Program (or any work based on the 198 198 + Program), you indicate your acceptance of this License to do so, and 199 199 + all its terms and conditions for copying, distributing or modifying 200 200 + the Program or works based on it. 201 201 + 202 202 + 6. Each time you redistribute the Program (or any work based on the 203 203 + Program), the recipient automatically receives a license from the 204 204 + original licensor to copy, distribute or modify the Program subject to 205 205 + these terms and conditions. You may not impose any further 206 206 + restrictions on the recipients' exercise of the rights granted herein. 207 207 + You are not responsible for enforcing compliance by third parties to 208 208 + this License. 209 209 + 210 210 + 7. If, as a consequence of a court judgment or allegation of patent 211 211 + infringement or for any other reason (not limited to patent issues), 212 212 + conditions are imposed on you (whether by court order, agreement or 213 213 + otherwise) that contradict the conditions of this License, they do not 214 214 + excuse you from the conditions of this License. If you cannot 215 215 + distribute so as to satisfy simultaneously your obligations under this 216 216 + License and any other pertinent obligations, then as a consequence you 217 217 + may not distribute the Program at all. For example, if a patent 218 218 + license would not permit royalty-free redistribution of the Program by 219 219 + all those who receive copies directly or indirectly through you, then 220 220 + the only way you could satisfy both it and this License would be to 221 221 + refrain entirely from distribution of the Program. 222 222 + 223 223 + If any portion of this section is held invalid or unenforceable under 224 224 + any particular circumstance, the balance of the section is intended to 225 225 + apply and the section as a whole is intended to apply in other 226 226 + circumstances. 227 227 + 228 228 + It is not the purpose of this section to induce you to infringe any 229 229 + patents or other property right claims or to contest validity of any 230 230 + such claims; this section has the sole purpose of protecting the 231 231 + integrity of the free software distribution system, which is 232 232 + implemented by public license practices. Many people have made 233 233 + generous contributions to the wide range of software distributed 234 234 + through that system in reliance on consistent application of that 235 235 + system; it is up to the author/donor to decide if he or she is willing 236 236 + to distribute software through any other system and a licensee cannot 237 237 + impose that choice. 238 238 + 239 239 + This section is intended to make thoroughly clear what is believed to 240 240 + be a consequence of the rest of this License. 241 241 +  242 242 + 8. If the distribution and/or use of the Program is restricted in 243 243 + certain countries either by patents or by copyrighted interfaces, the 244 244 + original copyright holder who places the Program under this License 245 245 + may add an explicit geographical distribution limitation excluding 246 246 + those countries, so that distribution is permitted only in or among 247 247 + countries not thus excluded. In such case, this License incorporates 248 248 + the limitation as if written in the body of this License. 249 249 + 250 250 + 9. The Free Software Foundation may publish revised and/or new versions 251 251 + of the General Public License from time to time. Such new versions will 252 252 + be similar in spirit to the present version, but may differ in detail to 253 253 + address new problems or concerns. 254 254 + 255 255 + Each version is given a distinguishing version number. If the Program 256 256 + specifies a version number of this License which applies to it and "any 257 257 + later version", you have the option of following the terms and conditions 258 258 + either of that version or of any later version published by the Free 259 259 + Software Foundation. If the Program does not specify a version number of 260 260 + this License, you may choose any version ever published by the Free Software 261 261 + Foundation. 262 262 + 263 263 + 10. If you wish to incorporate parts of the Program into other free 264 264 + programs whose distribution conditions are different, write to the author 265 265 + to ask for permission. For software which is copyrighted by the Free 266 266 + Software Foundation, write to the Free Software Foundation; we sometimes 267 267 + make exceptions for this. Our decision will be guided by the two goals 268 268 + of preserving the free status of all derivatives of our free software and 269 269 + of promoting the sharing and reuse of software generally. 270 270 + 271 271 + NO WARRANTY 272 272 + 273 273 + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY 274 274 + FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN 275 275 + OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES 276 276 + PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED 277 277 + OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF 278 278 + MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS 279 279 + TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE 280 280 + PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, 281 281 + REPAIR OR CORRECTION. 282 282 + 283 283 + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 284 284 + WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR 285 285 + REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, 286 286 + INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING 287 287 + OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED 288 288 + TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY 289 289 + YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER 290 290 + PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE 291 291 + POSSIBILITY OF SUCH DAMAGES. 292 292 + 293 293 + END OF TERMS AND CONDITIONS 294 294 +  295 295 + How to Apply These Terms to Your New Programs 296 296 + 297 297 + If you develop a new program, and you want it to be of the greatest 298 298 + possible use to the public, the best way to achieve this is to make it 299 299 + free software which everyone can redistribute and change under these terms. 300 300 + 301 301 + To do so, attach the following notices to the program. It is safest 302 302 + to attach them to the start of each source file to most effectively 303 303 + convey the exclusion of warranty; and each file should have at least 304 304 + the "copyright" line and a pointer to where the full notice is found. 305 305 + 306 306 + <one line to give the program's name and a brief idea of what it does.> 307 307 + Copyright (C) <year> <name of author> 308 308 + 309 309 + This program is free software; you can redistribute it and/or modify 310 310 + it under the terms of the GNU General Public License as published by 311 311 + the Free Software Foundation; either version 2 of the License, or 312 312 + (at your option) any later version. 313 313 + 314 314 + This program is distributed in the hope that it will be useful, 315 315 + but WITHOUT ANY WARRANTY; without even the implied warranty of 316 316 + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the 317 317 + GNU General Public License for more details. 318 318 + 319 319 + You should have received a copy of the GNU General Public License 320 320 + along with this program; if not, write to the Free Software 321 321 + Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA 322 322 + 323 323 + 324 324 + Also add information on how to contact you by electronic and paper mail. 325 325 + 326 326 + If the program is interactive, make it output a short notice like this 327 327 + when it starts in an interactive mode: 328 328 + 329 329 + Gnomovision version 69, Copyright (C) year name of author 330 330 + Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. 331 331 + This is free software, and you are welcome to redistribute it 332 332 + under certain conditions; type `show c' for details. 333 333 + 334 334 + The hypothetical commands `show w' and `show c' should show the appropriate 335 335 + parts of the General Public License. Of course, the commands you use may 336 336 + be called something other than `show w' and `show c'; they could even be 337 337 + mouse-clicks or menu items--whatever suits your program. 338 338 + 339 339 + You should also get your employer (if you work as a programmer) or your 340 340 + school, if any, to sign a "copyright disclaimer" for the program, if 341 341 + necessary. Here is a sample; alter the names: 342 342 + 343 343 + Yoyodyne, Inc., hereby disclaims all copyright interest in the program 344 344 + `Gnomovision' (which makes passes at compilers) written by James Hacker. 345 345 + 346 346 + <signature of Ty Coon>, 1 April 1989 347 347 + Ty Coon, President of Vice 348 348 + 349 349 + This General Public License does not permit incorporating your program into 350 350 + proprietary programs. If your program is a subroutine library, you may 351 351 + consider it more useful to permit linking proprietary applications with the 352 352 + library. If this is what you want to do, use the GNU Library General 353 353 + Public License instead of this License.
