pike.git/LICENSE:1: -  GNU GENERAL PUBLIC LICENSE -  Version 2, June 1991 + LICENSE    -  Copyright (C) 1989, 1991 Free Software Foundation, Inc., <http://fsf.org/> -  51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA -  Everyone is permitted to copy and distribute verbatim copies -  of this license document, but changing it is not allowed. + This module is licensed under the GPL (GNU Public License) version 2 or higher, + the MPL (Mozilla Public License), or LGPL (Lesser GNU Public License). A link to + each of these license is included in this document. You may choose under which + license you wish to use this module.    -  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 Lesser 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 -  -  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. -  -  {description} -  Copyright (C) {year} {fullname} -  -  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., -  51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 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) year 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 Lesser General - Public License instead of this License. + GPL http://www.gnu.org/licenses/gpl.txt + LGPL http://www.gnu.org/licenses/lgpl.txt + MPL http://www.mozilla.org/MPL/MPL-1.1.txt
