pike.git/src/COPYING:1: +  GNU GENERAL PUBLIC LICENSE +  Version 2, June 1991    -  +  Copyright (C) 1989, 1991 Free Software Foundation, Inc. +  675 Mass Ave, Cambridge, MA 02139, USA +  Everyone is permitted to copy and distribute verbatim copies +  of this license document, but changing it is not allowed. +  +  Preamble +  +  The licenses for most software are designed to take away your + freedom to share and change it. By contrast, the GNU General Public + License is intended to guarantee your freedom to share and change free + software--to make sure the software is free for all its users. This + General Public License applies to most of the Free Software + Foundation's software and to any other program whose authors commit to + using it. (Some other Free Software Foundation software is covered by + the GNU Library General Public License instead.) You can apply it to + your programs, too. +  +  When we speak of free software, we are referring to freedom, not + price. Our General Public Licenses are designed to make sure that you + have the freedom to distribute copies of free software (and charge for + this service if you wish), that you receive source code or can get it + if you want it, that you can change the software or use pieces of it + in new free programs; and that you know you can do these things. +  +  To protect your rights, we need to make restrictions that forbid + anyone to deny you these rights or to ask you to surrender the rights. + These restrictions translate to certain responsibilities for you if you + distribute copies of the software, or if you modify it. +  +  For example, if you distribute copies of such a program, whether + gratis or for a fee, you must give the recipients all the rights that + you have. You must make sure that they, too, receive or can get the + source code. And you must show them these terms so they know their + rights. +  +  We protect your rights with two steps: (1) copyright the software, and + (2) offer you this license which gives you legal permission to copy, + distribute and/or modify the software. +  +  Also, for each author's protection and ours, we want to make certain + that everyone understands that there is no warranty for this free + software. If the software is modified by someone else and passed on, we + want its recipients to know that what they have is not the original, so + that any problems introduced by others will not reflect on the original + authors' reputations. +  +  Finally, any free program is threatened constantly by software + patents. We wish to avoid the danger that redistributors of a free + program will individually obtain patent licenses, in effect making the + program proprietary. To prevent this, we have made it clear that any + patent must be licensed for everyone's free use or not licensed at all. +  +  The precise terms and conditions for copying, distribution and + modification follow. +  +  GNU GENERAL PUBLIC LICENSE +  TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION +  +  0. This License applies to any program or other work which contains + a notice placed by the copyright holder saying it may be distributed + under the terms of this General Public License. The "Program", below, + refers to any such program or work, and a "work based on the Program" + means either the Program or any derivative work under copyright law: + that is to say, a work containing the Program or a portion of it, + either verbatim or with modifications and/or translated into another + language. (Hereinafter, translation is included without limitation in + the term "modification".) Each licensee is addressed as "you". +  + Activities other than copying, distribution and modification are not + covered by this License; they are outside its scope. The act of + running the Program is not restricted, and the output from the Program + is covered only if its contents constitute a work based on the + Program (independent of having been made by running the Program). + Whether that is true depends on what the Program does. +  +  1. You may copy and distribute verbatim copies of the Program's + source code as you receive it, in any medium, provided that you + conspicuously and appropriately publish on each copy an appropriate + copyright notice and disclaimer of warranty; keep intact all the + notices that refer to this License and to the absence of any warranty; + and give any other recipients of the Program a copy of this License + along with the Program. +  + You may charge a fee for the physical act of transferring a copy, and + you may at your option offer warranty protection in exchange for a fee. +  +  2. You may modify your copy or copies of the Program or any portion + of it, thus forming a work based on the Program, and copy and + distribute such modifications or work under the terms of Section 1 + above, provided that you also meet all of these conditions: +  +  a) You must cause the modified files to carry prominent notices +  stating that you changed the files and the date of any change. +  +  b) You must cause any work that you distribute or publish, that in +  whole or in part contains or is derived from the Program or any +  part thereof, to be licensed as a whole at no charge to all third +  parties under the terms of this License. +  +  c) If the modified program normally reads commands interactively +  when run, you must cause it, when started running for such +  interactive use in the most ordinary way, to print or display an +  announcement including an appropriate copyright notice and a +  notice that there is no warranty (or else, saying that you provide +  a warranty) and that users may redistribute the program under +  these conditions, and telling the user how to view a copy of this +  License. (Exception: if the Program itself is interactive but +  does not normally print such an announcement, your work based on +  the Program is not required to print an announcement.) +  + These requirements apply to the modified work as a whole. If + identifiable sections of that work are not derived from the Program, + and can be reasonably considered independent and separate works in + themselves, then this License, and its terms, do not apply to those + sections when you distribute them as separate works. But when you + distribute the same sections as part of a whole which is a work based + on the Program, the distribution of the whole must be on the terms of + this License, whose permissions for other licensees extend to the + entire whole, and thus to each and every part regardless of who wrote it. +  + Thus, it is not the intent of this section to claim rights or contest + your rights to work written entirely by you; rather, the intent is to + exercise the right to control the distribution of derivative or + collective works based on the Program. +  + In addition, mere aggregation of another work not based on the Program + with the Program (or with a work based on the Program) on a volume of + a storage or distribution medium does not bring the other work under + the scope of this License. +  +  3. You may copy and distribute the Program (or a work based on it, + under Section 2) in object code or executable form under the terms of + Sections 1 and 2 above provided that you also do one of the following: +  +  a) Accompany it with the complete corresponding machine-readable +  source code, which must be distributed under the terms of Sections +  1 and 2 above on a medium customarily used for software interchange; or, +  +  b) Accompany it with a written offer, valid for at least three +  years, to give any third party, for a charge no more than your +  cost of physically performing source distribution, a complete +  machine-readable copy of the corresponding source code, to be +  distributed under the terms of Sections 1 and 2 above on a medium +  customarily used for software interchange; or, +  +  c) Accompany it with the information you received as to the offer +  to distribute corresponding source code. (This alternative is +  allowed only for noncommercial distribution and only if you +  received the program in object code or executable form with such +  an offer, in accord with Subsection b above.) +  + The source code for a work means the preferred form of the work for + making modifications to it. For an executable work, complete source + code means all the source code for all modules it contains, plus any + associated interface definition files, plus the scripts used to + control compilation and installation of the executable. However, as a + special exception, the source code distributed need not include + anything that is normally distributed (in either source or binary + form) with the major components (compiler, kernel, and so on) of the + operating system on which the executable runs, unless that component + itself accompanies the executable. +  + If distribution of executable or object code is made by offering + access to copy from a designated place, then offering equivalent + access to copy the source code from the same place counts as + distribution of the source code, even though third parties are not + compelled to copy the source along with the object code. +  +  4. You may not copy, modify, sublicense, or distribute the Program + except as expressly provided under this License. Any attempt + otherwise to copy, modify, sublicense or distribute the Program is + void, and will automatically terminate your rights under this License. + However, parties who have received copies, or rights, from you under + this License will not have their licenses terminated so long as such + parties remain in full compliance. +  +  5. You are not required to accept this License, since you have not + signed it. However, nothing else grants you permission to modify or + distribute the Program or its derivative works. These actions are + prohibited by law if you do not accept this License. Therefore, by + modifying or distributing the Program (or any work based on the + Program), you indicate your acceptance of this License to do so, and + all its terms and conditions for copying, distributing or modifying + the Program or works based on it. +  +  6. Each time you redistribute the Program (or any work based on the + Program), the recipient automatically receives a license from the + original licensor to copy, distribute or modify the Program subject to + these terms and conditions. You may not impose any further + restrictions on the recipients' exercise of the rights granted herein. + You are not responsible for enforcing compliance by third parties to + this License. +  +  7. If, as a consequence of a court judgment or allegation of patent + infringement or for any other reason (not limited to patent issues), + conditions are imposed on you (whether by court order, agreement or + otherwise) that contradict the conditions of this License, they do not + excuse you from the conditions of this License. If you cannot + distribute so as to satisfy simultaneously your obligations under this + License and any other pertinent obligations, then as a consequence you + may not distribute the Program at all. For example, if a patent + license would not permit royalty-free redistribution of the Program by + all those who receive copies directly or indirectly through you, then + the only way you could satisfy both it and this License would be to + refrain entirely from distribution of the Program. +  + If any portion of this section is held invalid or unenforceable under + any particular circumstance, the balance of the section is intended to + apply and the section as a whole is intended to apply in other + circumstances. +  + It is not the purpose of this section to induce you to infringe any + patents or other property right claims or to contest validity of any + such claims; this section has the sole purpose of protecting the + integrity of the free software distribution system, which is + implemented by public license practices. Many people have made + generous contributions to the wide range of software distributed + through that system in reliance on consistent application of that + system; it is up to the author/donor to decide if he or she is willing + to distribute software through any other system and a licensee cannot + impose that choice. +  + This section is intended to make thoroughly clear what is believed to + be a consequence of the rest of this License. +  +  8. If the distribution and/or use of the Program is restricted in + certain countries either by patents or by copyrighted interfaces, the + original copyright holder who places the Program under this License + may add an explicit geographical distribution limitation excluding + those countries, so that distribution is permitted only in or among + countries not thus excluded. In such case, this License incorporates + the limitation as if written in the body of this License. +  +  9. The Free Software Foundation may publish revised and/or new versions + of the General Public License from time to time. Such new versions will + be similar in spirit to the present version, but may differ in detail to + address new problems or concerns. +  + Each version is given a distinguishing version number. If the Program + specifies a version number of this License which applies to it and "any + later version", you have the option of following the terms and conditions + either of that version or of any later version published by the Free + Software Foundation. If the Program does not specify a version number of + this License, you may choose any version ever published by the Free Software + Foundation. +  +  10. If you wish to incorporate parts of the Program into other free + programs whose distribution conditions are different, write to the author + to ask for permission. For software which is copyrighted by the Free + Software Foundation, write to the Free Software Foundation; we sometimes + make exceptions for this. Our decision will be guided by the two goals + of preserving the free status of all derivatives of our free software and + of promoting the sharing and reuse of software generally. +  +  NO WARRANTY +  +  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY + FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN + OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES + PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED + OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF + MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS + TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE + PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, + REPAIR OR CORRECTION. +  +  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING + WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR + REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, + INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING + OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED + TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY + YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER + PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE + POSSIBILITY OF SUCH DAMAGES. +  +  END OF TERMS AND CONDITIONS +  +  Appendix: How to Apply These Terms to Your New Programs +  +  If you develop a new program, and you want it to be of the greatest + possible use to the public, the best way to achieve this is to make it + free software which everyone can redistribute and change under these terms. +  +  To do so, attach the following notices to the program. It is safest + to attach them to the start of each source file to most effectively + convey the exclusion of warranty; and each file should have at least + the "copyright" line and a pointer to where the full notice is found. +  +  <one line to give the program's name and a brief idea of what it does.> +  Copyright (C) 19yy <name of author> +  +  This program is free software; you can redistribute it and/or modify +  it under the terms of the GNU General Public License as published by +  the Free Software Foundation; either version 2 of the License, or +  (at your option) any later version. +  +  This program is distributed in the hope that it will be useful, +  but WITHOUT ANY WARRANTY; without even the implied warranty of +  MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the +  GNU General Public License for more details. +  +  You should have received a copy of the GNU General Public License +  along with this program; if not, write to the Free Software +  Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA. +  + Also add information on how to contact you by electronic and paper mail. +  + If the program is interactive, make it output a short notice like this + when it starts in an interactive mode: +  +  Gnomovision version 69, Copyright (C) 19yy name of author +  Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. +  This is free software, and you are welcome to redistribute it +  under certain conditions; type `show c' for details. +  + The hypothetical commands `show w' and `show c' should show the appropriate + parts of the General Public License. Of course, the commands you use may + be called something other than `show w' and `show c'; they could even be + mouse-clicks or menu items--whatever suits your program. +  + You should also get your employer (if you work as a programmer) or your + school, if any, to sign a "copyright disclaimer" for the program, if + necessary. Here is a sample; alter the names: +  +  Yoyodyne, Inc., hereby disclaims all copyright interest in the program +  `Gnomovision' (which makes passes at compilers) written by James Hacker. +  +  <signature of Ty Coon>, 1 April 1989 +  Ty Coon, President of Vice +  + This General Public License does not permit incorporating your program into + proprietary programs. If your program is a subroutine library, you may + consider it more useful to permit linking proprietary applications with the + library. If this is what you want to do, use the GNU Library General + Public License instead of this License.   Newline at end of file added.
