1Valid-License-Identifier: GPL-1.0+ 2SPDX-URL: https://spdx.org/licenses/GPL-1.0.html 3Usage-Guide: 4 The GNU General Public License (GPL) version 1 should not be used in new 5 code. For existing kernel code the 'or any later version' option is 6 required to be compatible with the general license of the project: GPLv2. 7 To use the license in source code, put the following SPDX tag/value pair 8 into a comment according to the placement guidelines in the licensing 9 rules documentation: 10 SPDX-License-Identifier: GPL-1.0+ 11License-Text: 12 13 GNU GENERAL PUBLIC LICENSE 14 Version 1, February 1989 15 16 Copyright (C) 1989 Free Software Foundation, Inc. 17 <https://fsf.org/> 18 19 Everyone is permitted to copy and distribute verbatim copies 20 of this license document, but changing it is not allowed. 21 22 Preamble 23 24 The license agreements of most software companies try to keep users 25at the mercy of those companies. By contrast, our General Public 26License is intended to guarantee your freedom to share and change free 27software--to make sure the software is free for all its users. The 28General Public License applies to the Free Software Foundation's 29software and to any other program whose authors commit to using it. 30You can use it for your programs, too. 31 32 When we speak of free software, we are referring to freedom, not 33price. Specifically, the General Public License is designed to make 34sure that you have the freedom to give away or sell copies of free 35software, that you receive source code or can get it if you want it, 36that you can change the software or use pieces of it in new free 37programs; and that you know you can do these things. 38 39 To protect your rights, we need to make restrictions that forbid 40anyone to deny you these rights or to ask you to surrender the rights. 41These restrictions translate to certain responsibilities for you if you 42distribute copies of the software, or if you modify it. 43 44 For example, if you distribute copies of a such a program, whether 45gratis or for a fee, you must give the recipients all the rights that 46you have. You must make sure that they, too, receive or can get the 47source code. And you must tell them their rights. 48 49 We protect your rights with two steps: (1) copyright the software, and 50(2) offer you this license which gives you legal permission to copy, 51distribute and/or modify the software. 52 53 Also, for each author's protection and ours, we want to make certain 54that everyone understands that there is no warranty for this free 55software. If the software is modified by someone else and passed on, we 56want its recipients to know that what they have is not the original, so 57that any problems introduced by others will not reflect on the original 58authors' reputations. 59 60 The precise terms and conditions for copying, distribution and 61modification follow. 62 63 GNU GENERAL PUBLIC LICENSE 64 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 65 66 0. This License Agreement applies to any program or other work which 67contains a notice placed by the copyright holder saying it may be 68distributed under the terms of this General Public License. The 69"Program", below, refers to any such program or work, and a "work based 70on the Program" means either the Program or any work containing the 71Program or a portion of it, either verbatim or with modifications. Each 72licensee is addressed as "you". 73 74 1. You may copy and distribute verbatim copies of the Program's source 75code as you receive it, in any medium, provided that you conspicuously and 76appropriately publish on each copy an appropriate copyright notice and 77disclaimer of warranty; keep intact all the notices that refer to this 78General Public License and to the absence of any warranty; and give any 79other recipients of the Program a copy of this General Public License 80along with the Program. You may charge a fee for the physical act of 81transferring a copy. 82 83 2. You may modify your copy or copies of the Program or any portion of 84it, and copy and distribute such modifications under the terms of Paragraph 851 above, provided that you also do the following: 86 87 a) cause the modified files to carry prominent notices stating that 88 you changed the files and the date of any change; and 89 90 b) cause the whole of any work that you distribute or publish, that 91 in whole or in part contains the Program or any part thereof, either 92 with or without modifications, to be licensed at no charge to all 93 third parties under the terms of this General Public License (except 94 that you may choose to grant warranty protection to some or all 95 third parties, at your option). 96 97 c) If the modified program normally reads commands interactively when 98 run, you must cause it, when started running for such interactive use 99 in the simplest and most usual way, to print or display an 100 announcement including an appropriate copyright notice and a notice 101 that there is no warranty (or else, saying that you provide a 102 warranty) and that users may redistribute the program under these 103 conditions, and telling the user how to view a copy of this General 104 Public License. 105 106 d) You may charge a fee for the physical act of transferring a 107 copy, and you may at your option offer warranty protection in 108 exchange for a fee. 109 110Mere aggregation of another independent work with the Program (or its 111derivative) on a volume of a storage or distribution medium does not bring 112the other work under the scope of these terms. 113 114 3. You may copy and distribute the Program (or a portion or derivative of 115it, under Paragraph 2) in object code or executable form under the terms of 116Paragraphs 1 and 2 above provided that you also do one of the following: 117 118 a) accompany it with the complete corresponding machine-readable 119 source code, which must be distributed under the terms of 120 Paragraphs 1 and 2 above; or, 121 122 b) accompany it with a written offer, valid for at least three 123 years, to give any third party free (except for a nominal charge 124 for the cost of distribution) a complete machine-readable copy of the 125 corresponding source code, to be distributed under the terms of 126 Paragraphs 1 and 2 above; or, 127 128 c) accompany it with the information you received as to where the 129 corresponding source code may be obtained. (This alternative is 130 allowed only for noncommercial distribution and only if you 131 received the program in object code or executable form alone.) 132 133Source code for a work means the preferred form of the work for making 134modifications to it. For an executable file, complete source code means 135all the source code for all modules it contains; but, as a special 136exception, it need not include source code for modules which are standard 137libraries that accompany the operating system on which the executable 138file runs, or for standard header files or definitions files that 139accompany that operating system. 140 141 4. You may not copy, modify, sublicense, distribute or transfer the 142Program except as expressly provided under this General Public License. 143Any attempt otherwise to copy, modify, sublicense, distribute or transfer 144the Program is void, and will automatically terminate your rights to use 145the Program under this License. However, parties who have received 146copies, or rights to use copies, from you under this General Public 147License will not have their licenses terminated so long as such parties 148remain in full compliance. 149 150 5. By copying, distributing or modifying the Program (or any work based 151on the Program) you indicate your acceptance of this license to do so, 152and all its terms and conditions. 153 154 6. Each time you redistribute the Program (or any work based on the 155Program), the recipient automatically receives a license from the original 156licensor to copy, distribute or modify the Program subject to these 157terms and conditions. You may not impose any further restrictions on the 158recipients' exercise of the rights granted herein. 159 160 7. The Free Software Foundation may publish revised and/or new versions 161of the General Public License from time to time. Such new versions will 162be similar in spirit to the present version, but may differ in detail to 163address new problems or concerns. 164 165Each version is given a distinguishing version number. If the Program 166specifies a version number of the license which applies to it and "any 167later version", you have the option of following the terms and conditions 168either of that version or of any later version published by the Free 169Software Foundation. If the Program does not specify a version number of 170the license, you may choose any version ever published by the Free Software 171Foundation. 172 173 8. If you wish to incorporate parts of the Program into other free 174programs whose distribution conditions are different, write to the author 175to ask for permission. For software which is copyrighted by the Free 176Software Foundation, write to the Free Software Foundation; we sometimes 177make exceptions for this. Our decision will be guided by the two goals 178of preserving the free status of all derivatives of our free software and 179of promoting the sharing and reuse of software generally. 180 181 NO WARRANTY 182 183 9. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY 184FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN 185OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES 186PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED 187OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF 188MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS 189TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE 190PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, 191REPAIR OR CORRECTION. 192 193 10. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 194WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR 195REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, 196INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING 197OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED 198TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY 199YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER 200PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE 201POSSIBILITY OF SUCH DAMAGES. 202 203 END OF TERMS AND CONDITIONS 204 205 Appendix: How to Apply These Terms to Your New Programs 206 207 If you develop a new program, and you want it to be of the greatest 208possible use to humanity, the best way to achieve this is to make it 209free software which everyone can redistribute and change under these 210terms. 211 212 To do so, attach the following notices to the program. It is safest to 213attach them to the start of each source file to most effectively convey 214the exclusion of warranty; and each file should have at least the 215"copyright" line and a pointer to where the full notice is found. 216 217 <one line to give the program's name and a brief idea of what it does.> 218 Copyright (C) 19yy <name of author> 219 220 This program is free software; you can redistribute it and/or modify 221 it under the terms of the GNU General Public License as published by 222 the Free Software Foundation; either version 1, or (at your option) 223 any later version. 224 225 This program is distributed in the hope that it will be useful, 226 but WITHOUT ANY WARRANTY; without even the implied warranty of 227 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the 228 GNU General Public License for more details. 229 230 You should have received a copy of the GNU General Public License 231 along with this program; if not, see <https://www.gnu.org/licenses/>. 232 233Also add information on how to contact you by electronic and paper mail. 234 235If the program is interactive, make it output a short notice like this 236when it starts in an interactive mode: 237 238 Gnomovision version 69, Copyright (C) 19xx name of author 239 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. 240 This is free software, and you are welcome to redistribute it 241 under certain conditions; type `show c' for details. 242 243The hypothetical commands `show w' and `show c' should show the 244appropriate parts of the General Public License. Of course, the 245commands you use may be called something other than `show w' and `show 246c'; they could even be mouse-clicks or menu items--whatever suits your 247program. 248 249You should also get your employer (if you work as a programmer) or your 250school, if any, to sign a "copyright disclaimer" for the program, if 251necessary. Here a sample; alter the names: 252 253 Yoyodyne, Inc., hereby disclaims all copyright interest in the 254 program `Gnomovision' (a program to direct compilers to make passes 255 at assemblers) written by James Hacker. 256 257 <signature of Ty Coon>, 1 April 1989 258 Ty Coon, President of Vice 259 260That's all there is to it! 261
