1 2The kconfig parser and frontends are extracted from the Linux kernel 3source tree, which is covered by the GPLv2 only. As Linus Torvalds puts it: 4 5 > Also note that the only valid version of the GPL as far as the kernel 6 > is concerned is _this_ particular version of the license (ie v2, not 7 > v2.2 or v3.x or whatever), unless explicitly otherwise stated. 8 9Although the above quote explictly mentions the Linux kernel, it is my 10understanding that the whole Linux kernel source tree is covered by this 11sentence, even non-kernel source code. As such, the license that applies 12to the kconfig parser and frontends, as published in this package, are 13also covered by this sentence, and available under the GPLv2, and not any 14other version of the GPL, unless otherwise stated. 15 16---------------------------------------- 17 18 GNU GENERAL PUBLIC LICENSE 19 Version 2, June 1991 20 21 Copyright (C) 1989, 1991 Free Software Foundation, Inc. 22 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA 23 Everyone is permitted to copy and distribute verbatim copies 24 of this license document, but changing it is not allowed. 25 26 Preamble 27 28 The licenses for most software are designed to take away your 29freedom to share and change it. By contrast, the GNU General Public 30License is intended to guarantee your freedom to share and change free 31software--to make sure the software is free for all its users. This 32General Public License applies to most of the Free Software 33Foundation's software and to any other program whose authors commit to 34using it. (Some other Free Software Foundation software is covered by 35the GNU Library General Public License instead.) You can apply it to 36your programs, too. 37 38 When we speak of free software, we are referring to freedom, not 39price. Our General Public Licenses are designed to make sure that you 40have the freedom to distribute copies of free software (and charge for 41this service if you wish), that you receive source code or can get it 42if you want it, that you can change the software or use pieces of it 43in new free programs; and that you know you can do these things. 44 45 To protect your rights, we need to make restrictions that forbid 46anyone to deny you these rights or to ask you to surrender the rights. 47These restrictions translate to certain responsibilities for you if you 48distribute copies of the software, or if you modify it. 49 50 For example, if you distribute copies of such a program, whether 51gratis or for a fee, you must give the recipients all the rights that 52you have. You must make sure that they, too, receive or can get the 53source code. And you must show them these terms so they know their 54rights. 55 56 We protect your rights with two steps: (1) copyright the software, and 57(2) offer you this license which gives you legal permission to copy, 58distribute and/or modify the software. 59 60 Also, for each author's protection and ours, we want to make certain 61that everyone understands that there is no warranty for this free 62software. If the software is modified by someone else and passed on, we 63want its recipients to know that what they have is not the original, so 64that any problems introduced by others will not reflect on the original 65authors' reputations. 66 67 Finally, any free program is threatened constantly by software 68patents. We wish to avoid the danger that redistributors of a free 69program will individually obtain patent licenses, in effect making the 70program proprietary. To prevent this, we have made it clear that any 71patent must be licensed for everyone's free use or not licensed at all. 72 73 The precise terms and conditions for copying, distribution and 74modification follow. 75 76 GNU GENERAL PUBLIC LICENSE 77 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 78 79 0. This License applies to any program or other work which contains 80a notice placed by the copyright holder saying it may be distributed 81under the terms of this General Public License. The "Program", below, 82refers to any such program or work, and a "work based on the Program" 83means either the Program or any derivative work under copyright law: 84that is to say, a work containing the Program or a portion of it, 85either verbatim or with modifications and/or translated into another 86language. (Hereinafter, translation is included without limitation in 87the term "modification".) Each licensee is addressed as "you". 88 89Activities other than copying, distribution and modification are not 90covered by this License; they are outside its scope. The act of 91running the Program is not restricted, and the output from the Program 92is covered only if its contents constitute a work based on the 93Program (independent of having been made by running the Program). 94Whether that is true depends on what the Program does. 95 96 1. You may copy and distribute verbatim copies of the Program's 97source code as you receive it, in any medium, provided that you 98conspicuously and appropriately publish on each copy an appropriate 99copyright notice and disclaimer of warranty; keep intact all the 100notices that refer to this License and to the absence of any warranty; 101and give any other recipients of the Program a copy of this License 102along with the Program. 103 104You may charge a fee for the physical act of transferring a copy, and 105you may at your option offer warranty protection in exchange for a fee. 106 107 2. You may modify your copy or copies of the Program or any portion 108of it, thus forming a work based on the Program, and copy and 109distribute such modifications or work under the terms of Section 1 110above, provided that you also meet all of these conditions: 111 112 a) You must cause the modified files to carry prominent notices 113 stating that you changed the files and the date of any change. 114 115 b) You must cause any work that you distribute or publish, that in 116 whole or in part contains or is derived from the Program or any 117 part thereof, to be licensed as a whole at no charge to all third 118 parties under the terms of this License. 119 120 c) If the modified program normally reads commands interactively 121 when run, you must cause it, when started running for such 122 interactive use in the most ordinary way, to print or display an 123 announcement including an appropriate copyright notice and a 124 notice that there is no warranty (or else, saying that you provide 125 a warranty) and that users may redistribute the program under 126 these conditions, and telling the user how to view a copy of this 127 License. (Exception: if the Program itself is interactive but 128 does not normally print such an announcement, your work based on 129 the Program is not required to print an announcement.) 130 131These requirements apply to the modified work as a whole. If 132identifiable sections of that work are not derived from the Program, 133and can be reasonably considered independent and separate works in 134themselves, then this License, and its terms, do not apply to those 135sections when you distribute them as separate works. But when you 136distribute the same sections as part of a whole which is a work based 137on the Program, the distribution of the whole must be on the terms of 138this License, whose permissions for other licensees extend to the 139entire whole, and thus to each and every part regardless of who wrote it. 140 141Thus, it is not the intent of this section to claim rights or contest 142your rights to work written entirely by you; rather, the intent is to 143exercise the right to control the distribution of derivative or 144collective works based on the Program. 145 146In addition, mere aggregation of another work not based on the Program 147with the Program (or with a work based on the Program) on a volume of 148a storage or distribution medium does not bring the other work under 149the scope of this License. 150 151 3. You may copy and distribute the Program (or a work based on it, 152under Section 2) in object code or executable form under the terms of 153Sections 1 and 2 above provided that you also do one of the following: 154 155 a) Accompany it with the complete corresponding machine-readable 156 source code, which must be distributed under the terms of Sections 157 1 and 2 above on a medium customarily used for software interchange; or, 158 159 b) Accompany it with a written offer, valid for at least three 160 years, to give any third party, for a charge no more than your 161 cost of physically performing source distribution, a complete 162 machine-readable copy of the corresponding source code, to be 163 distributed under the terms of Sections 1 and 2 above on a medium 164 customarily used for software interchange; or, 165 166 c) Accompany it with the information you received as to the offer 167 to distribute corresponding source code. (This alternative is 168 allowed only for noncommercial distribution and only if you 169 received the program in object code or executable form with such 170 an offer, in accord with Subsection b above.) 171 172The source code for a work means the preferred form of the work for 173making modifications to it. For an executable work, complete source 174code means all the source code for all modules it contains, plus any 175associated interface definition files, plus the scripts used to 176control compilation and installation of the executable. However, as a 177special exception, the source code distributed need not include 178anything that is normally distributed (in either source or binary 179form) with the major components (compiler, kernel, and so on) of the 180operating system on which the executable runs, unless that component 181itself accompanies the executable. 182 183If distribution of executable or object code is made by offering 184access to copy from a designated place, then offering equivalent 185access to copy the source code from the same place counts as 186distribution of the source code, even though third parties are not 187compelled to copy the source along with the object code. 188 189 4. You may not copy, modify, sublicense, or distribute the Program 190except as expressly provided under this License. Any attempt 191otherwise to copy, modify, sublicense or distribute the Program is 192void, and will automatically terminate your rights under this License. 193However, parties who have received copies, or rights, from you under 194this License will not have their licenses terminated so long as such 195parties remain in full compliance. 196 197 5. You are not required to accept this License, since you have not 198signed it. However, nothing else grants you permission to modify or 199distribute the Program or its derivative works. These actions are 200prohibited by law if you do not accept this License. Therefore, by 201modifying or distributing the Program (or any work based on the 202Program), you indicate your acceptance of this License to do so, and 203all its terms and conditions for copying, distributing or modifying 204the Program or works based on it. 205 206 6. Each time you redistribute the Program (or any work based on the 207Program), the recipient automatically receives a license from the 208original licensor to copy, distribute or modify the Program subject to 209these terms and conditions. You may not impose any further 210restrictions on the recipients' exercise of the rights granted herein. 211You are not responsible for enforcing compliance by third parties to 212this License. 213 214 7. If, as a consequence of a court judgment or allegation of patent 215infringement or for any other reason (not limited to patent issues), 216conditions are imposed on you (whether by court order, agreement or 217otherwise) that contradict the conditions of this License, they do not 218excuse you from the conditions of this License. If you cannot 219distribute so as to satisfy simultaneously your obligations under this 220License and any other pertinent obligations, then as a consequence you 221may not distribute the Program at all. For example, if a patent 222license would not permit royalty-free redistribution of the Program by 223all those who receive copies directly or indirectly through you, then 224the only way you could satisfy both it and this License would be to 225refrain entirely from distribution of the Program. 226 227If any portion of this section is held invalid or unenforceable under 228any particular circumstance, the balance of the section is intended to 229apply and the section as a whole is intended to apply in other 230circumstances. 231 232It is not the purpose of this section to induce you to infringe any 233patents or other property right claims or to contest validity of any 234such claims; this section has the sole purpose of protecting the 235integrity of the free software distribution system, which is 236implemented by public license practices. Many people have made 237generous contributions to the wide range of software distributed 238through that system in reliance on consistent application of that 239system; it is up to the author/donor to decide if he or she is willing 240to distribute software through any other system and a licensee cannot 241impose that choice. 242 243This section is intended to make thoroughly clear what is believed to 244be a consequence of the rest of this License. 245 246 8. If the distribution and/or use of the Program is restricted in 247certain countries either by patents or by copyrighted interfaces, the 248original copyright holder who places the Program under this License 249may add an explicit geographical distribution limitation excluding 250those countries, so that distribution is permitted only in or among 251countries not thus excluded. In such case, this License incorporates 252the limitation as if written in the body of this License. 253 254 9. The Free Software Foundation may publish revised and/or new versions 255of the General Public License from time to time. Such new versions will 256be similar in spirit to the present version, but may differ in detail to 257address new problems or concerns. 258 259Each version is given a distinguishing version number. If the Program 260specifies a version number of this License which applies to it and "any 261later version", you have the option of following the terms and conditions 262either of that version or of any later version published by the Free 263Software Foundation. If the Program does not specify a version number of 264this License, you may choose any version ever published by the Free Software 265Foundation. 266 267 10. If you wish to incorporate parts of the Program into other free 268programs whose distribution conditions are different, write to the author 269to ask for permission. For software which is copyrighted by the Free 270Software Foundation, write to the Free Software Foundation; we sometimes 271make exceptions for this. Our decision will be guided by the two goals 272of preserving the free status of all derivatives of our free software and 273of promoting the sharing and reuse of software generally. 274 275 NO WARRANTY 276 277 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY 278FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN 279OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES 280PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED 281OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF 282MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS 283TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE 284PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, 285REPAIR OR CORRECTION. 286 287 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 288WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR 289REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, 290INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING 291OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED 292TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY 293YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER 294PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE 295POSSIBILITY OF SUCH DAMAGES. 296 297 END OF TERMS AND CONDITIONS 298 299 How to Apply These Terms to Your New Programs 300 301 If you develop a new program, and you want it to be of the greatest 302possible use to the public, the best way to achieve this is to make it 303free software which everyone can redistribute and change under these terms. 304 305 To do so, attach the following notices to the program. It is safest 306to attach them to the start of each source file to most effectively 307convey the exclusion of warranty; and each file should have at least 308the "copyright" line and a pointer to where the full notice is found. 309 310 <one line to give the program's name and a brief idea of what it does.> 311 Copyright (C) <year> <name of author> 312 313 This program is free software; you can redistribute it and/or modify 314 it under the terms of the GNU General Public License as published by 315 the Free Software Foundation; either version 2 of the License, or 316 (at your option) any later version. 317 318 This program is distributed in the hope that it will be useful, 319 but WITHOUT ANY WARRANTY; without even the implied warranty of 320 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the 321 GNU General Public License for more details. 322 323 You should have received a copy of the GNU General Public License 324 along with this program; if not, write to the Free Software 325 Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA 326 327 328Also add information on how to contact you by electronic and paper mail. 329 330If the program is interactive, make it output a short notice like this 331when it starts in an interactive mode: 332 333 Gnomovision version 69, Copyright (C) year name of author 334 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. 335 This is free software, and you are welcome to redistribute it 336 under certain conditions; type `show c' for details. 337 338The hypothetical commands `show w' and `show c' should show the appropriate 339parts of the General Public License. Of course, the commands you use may 340be called something other than `show w' and `show c'; they could even be 341mouse-clicks or menu items--whatever suits your program. 342 343You should also get your employer (if you work as a programmer) or your 344school, if any, to sign a "copyright disclaimer" for the program, if 345necessary. Here is a sample; alter the names: 346 347 Yoyodyne, Inc., hereby disclaims all copyright interest in the program 348 `Gnomovision' (which makes passes at compilers) written by James Hacker. 349 350 <signature of Ty Coon>, 1 April 1989 351 Ty Coon, President of Vice 352 353This General Public License does not permit incorporating your program into 354proprietary programs. If your program is a subroutine library, you may 355consider it more useful to permit linking proprietary applications with the 356library. If this is what you want to do, use the GNU Library General 357Public License instead of this License. 358
