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. 17 675 Mass Ave, Cambridge, MA 02139, USA 18 Everyone is permitted to copy and distribute verbatim copies 19 of this license document, but changing it is not allowed. 20 21 Preamble 22 23 The license agreements of most software companies try to keep users 24at the mercy of those companies. By contrast, our General Public 25License is intended to guarantee your freedom to share and change free 26software--to make sure the software is free for all its users. The 27General Public License applies to the Free Software Foundation's 28software and to any other program whose authors commit to using it. 29You can use it for your programs, too. 30 31 When we speak of free software, we are referring to freedom, not 32price. Specifically, the General Public License is designed to make 33sure that you have the freedom to give away or sell copies of free 34software, that you receive source code or can get it if you want it, 35that you can change the software or use pieces of it in new free 36programs; and that you know you can do these things. 37 38 To protect your rights, we need to make restrictions that forbid 39anyone to deny you these rights or to ask you to surrender the rights. 40These restrictions translate to certain responsibilities for you if you 41distribute copies of the software, or if you modify it. 42 43 For example, if you distribute copies of a such a program, whether 44gratis or for a fee, you must give the recipients all the rights that 45you have. You must make sure that they, too, receive or can get the 46source code. And you must tell them their rights. 47 48 We protect your rights with two steps: (1) copyright the software, and 49(2) offer you this license which gives you legal permission to copy, 50distribute and/or modify the software. 51 52 Also, for each author's protection and ours, we want to make certain 53that everyone understands that there is no warranty for this free 54software. If the software is modified by someone else and passed on, we 55want its recipients to know that what they have is not the original, so 56that any problems introduced by others will not reflect on the original 57authors' reputations. 58 59 The precise terms and conditions for copying, distribution and 60modification follow. 61 62 GNU GENERAL PUBLIC LICENSE 63 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 64 65 0. This License Agreement applies to any program or other work which 66contains a notice placed by the copyright holder saying it may be 67distributed under the terms of this General Public License. The 68"Program", below, refers to any such program or work, and a "work based 69on the Program" means either the Program or any work containing the 70Program or a portion of it, either verbatim or with modifications. Each 71licensee is addressed as "you". 72 73 1. You may copy and distribute verbatim copies of the Program's source 74code as you receive it, in any medium, provided that you conspicuously and 75appropriately publish on each copy an appropriate copyright notice and 76disclaimer of warranty; keep intact all the notices that refer to this 77General Public License and to the absence of any warranty; and give any 78other recipients of the Program a copy of this General Public License 79along with the Program. You may charge a fee for the physical act of 80transferring a copy. 81 82 2. You may modify your copy or copies of the Program or any portion of 83it, and copy and distribute such modifications under the terms of Paragraph 841 above, provided that you also do the following: 85 86 a) cause the modified files to carry prominent notices stating that 87 you changed the files and the date of any change; and 88 89 b) cause the whole of any work that you distribute or publish, that 90 in whole or in part contains the Program or any part thereof, either 91 with or without modifications, to be licensed at no charge to all 92 third parties under the terms of this General Public License (except 93 that you may choose to grant warranty protection to some or all 94 third parties, at your option). 95 96 c) If the modified program normally reads commands interactively when 97 run, you must cause it, when started running for such interactive use 98 in the simplest and most usual way, to print or display an 99 announcement including an appropriate copyright notice and a notice 100 that there is no warranty (or else, saying that you provide a 101 warranty) and that users may redistribute the program under these 102 conditions, and telling the user how to view a copy of this General 103 Public License. 104 105 d) You may charge a fee for the physical act of transferring a 106 copy, and you may at your option offer warranty protection in 107 exchange for a fee. 108 109Mere aggregation of another independent work with the Program (or its 110derivative) on a volume of a storage or distribution medium does not bring 111the other work under the scope of these terms. 112 113 3. You may copy and distribute the Program (or a portion or derivative of 114it, under Paragraph 2) in object code or executable form under the terms of 115Paragraphs 1 and 2 above provided that you also do one of the following: 116 117 a) accompany it with the complete corresponding machine-readable 118 source code, which must be distributed under the terms of 119 Paragraphs 1 and 2 above; or, 120 121 b) accompany it with a written offer, valid for at least three 122 years, to give any third party free (except for a nominal charge 123 for the cost of distribution) a complete machine-readable copy of the 124 corresponding source code, to be distributed under the terms of 125 Paragraphs 1 and 2 above; or, 126 127 c) accompany it with the information you received as to where the 128 corresponding source code may be obtained. (This alternative is 129 allowed only for noncommercial distribution and only if you 130 received the program in object code or executable form alone.) 131 132Source code for a work means the preferred form of the work for making 133modifications to it. For an executable file, complete source code means 134all the source code for all modules it contains; but, as a special 135exception, it need not include source code for modules which are standard 136libraries that accompany the operating system on which the executable 137file runs, or for standard header files or definitions files that 138accompany that operating system. 139 140 4. You may not copy, modify, sublicense, distribute or transfer the 141Program except as expressly provided under this General Public License. 142Any attempt otherwise to copy, modify, sublicense, distribute or transfer 143the Program is void, and will automatically terminate your rights to use 144the Program under this License. However, parties who have received 145copies, or rights to use copies, from you under this General Public 146License will not have their licenses terminated so long as such parties 147remain in full compliance. 148 149 5. By copying, distributing or modifying the Program (or any work based 150on the Program) you indicate your acceptance of this license to do so, 151and all its terms and conditions. 152 153 6. Each time you redistribute the Program (or any work based on the 154Program), the recipient automatically receives a license from the original 155licensor to copy, distribute or modify the Program subject to these 156terms and conditions. You may not impose any further restrictions on the 157recipients' exercise of the rights granted herein. 158 159 7. The Free Software Foundation may publish revised and/or new versions 160of the General Public License from time to time. Such new versions will 161be similar in spirit to the present version, but may differ in detail to 162address new problems or concerns. 163 164Each version is given a distinguishing version number. If the Program 165specifies a version number of the license which applies to it and "any 166later version", you have the option of following the terms and conditions 167either of that version or of any later version published by the Free 168Software Foundation. If the Program does not specify a version number of 169the license, you may choose any version ever published by the Free Software 170Foundation. 171 172 8. If you wish to incorporate parts of the Program into other free 173programs whose distribution conditions are different, write to the author 174to ask for permission. For software which is copyrighted by the Free 175Software Foundation, write to the Free Software Foundation; we sometimes 176make exceptions for this. Our decision will be guided by the two goals 177of preserving the free status of all derivatives of our free software and 178of promoting the sharing and reuse of software generally. 179 180 NO WARRANTY 181 182 9. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY 183FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN 184OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES 185PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED 186OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF 187MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS 188TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE 189PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, 190REPAIR OR CORRECTION. 191 192 10. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 193WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR 194REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, 195INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING 196OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED 197TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY 198YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER 199PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE 200POSSIBILITY OF SUCH DAMAGES. 201 202 END OF TERMS AND CONDITIONS 203 204 Appendix: How to Apply These Terms to Your New Programs 205 206 If you develop a new program, and you want it to be of the greatest 207possible use to humanity, the best way to achieve this is to make it 208free software which everyone can redistribute and change under these 209terms. 210 211 To do so, attach the following notices to the program. It is safest to 212attach them to the start of each source file to most effectively convey 213the exclusion of warranty; and each file should have at least the 214"copyright" line and a pointer to where the full notice is found. 215 216 <one line to give the program's name and a brief idea of what it does.> 217 Copyright (C) 19yy <name of author> 218 219 This program is free software; you can redistribute it and/or modify 220 it under the terms of the GNU General Public License as published by 221 the Free Software Foundation; either version 1, or (at your option) 222 any later version. 223 224 This program is distributed in the hope that it will be useful, 225 but WITHOUT ANY WARRANTY; without even the implied warranty of 226 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the 227 GNU General Public License for more details. 228 229 You should have received a copy of the GNU General Public License 230 along with this program; if not, write to the Free Software 231 Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA. 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
