joachim99@2: GNU GENERAL PUBLIC LICENSE joachim99@2: Version 2, June 1991 joachim99@2: joachim99@2: Copyright (C) 1989, 1991 Free Software Foundation, Inc. joachim99@69: 51 Franklin Steet, Fifth Floor, Boston, MA 02111-1307 USA joachim99@2: Everyone is permitted to copy and distribute verbatim copies joachim99@2: of this license document, but changing it is not allowed. joachim99@2: joachim99@2: Preamble joachim99@2: joachim99@2: The licenses for most software are designed to take away your joachim99@2: freedom to share and change it. By contrast, the GNU General Public joachim99@2: License is intended to guarantee your freedom to share and change free joachim99@2: software--to make sure the software is free for all its users. This joachim99@2: General Public License applies to most of the Free Software joachim99@2: Foundation's software and to any other program whose authors commit to joachim99@2: using it. (Some other Free Software Foundation software is covered by joachim99@2: the GNU Library General Public License instead.) You can apply it to joachim99@2: your programs, too. joachim99@2: joachim99@2: When we speak of free software, we are referring to freedom, not joachim99@2: price. Our General Public Licenses are designed to make sure that you joachim99@2: have the freedom to distribute copies of free software (and charge for joachim99@2: this service if you wish), that you receive source code or can get it joachim99@2: if you want it, that you can change the software or use pieces of it joachim99@2: in new free programs; and that you know you can do these things. joachim99@2: joachim99@2: To protect your rights, we need to make restrictions that forbid joachim99@2: anyone to deny you these rights or to ask you to surrender the rights. joachim99@2: These restrictions translate to certain responsibilities for you if you joachim99@2: distribute copies of the software, or if you modify it. joachim99@2: joachim99@2: For example, if you distribute copies of such a program, whether joachim99@2: gratis or for a fee, you must give the recipients all the rights that joachim99@2: you have. You must make sure that they, too, receive or can get the joachim99@2: source code. And you must show them these terms so they know their joachim99@2: rights. joachim99@2: joachim99@2: We protect your rights with two steps: (1) copyright the software, and joachim99@2: (2) offer you this license which gives you legal permission to copy, joachim99@2: distribute and/or modify the software. joachim99@2: joachim99@2: Also, for each author's protection and ours, we want to make certain joachim99@2: that everyone understands that there is no warranty for this free joachim99@2: software. If the software is modified by someone else and passed on, we joachim99@2: want its recipients to know that what they have is not the original, so joachim99@2: that any problems introduced by others will not reflect on the original joachim99@2: authors' reputations. joachim99@2: joachim99@2: Finally, any free program is threatened constantly by software joachim99@2: patents. We wish to avoid the danger that redistributors of a free joachim99@2: program will individually obtain patent licenses, in effect making the joachim99@2: program proprietary. To prevent this, we have made it clear that any joachim99@2: patent must be licensed for everyone's free use or not licensed at all. joachim99@2: joachim99@2: The precise terms and conditions for copying, distribution and joachim99@2: modification follow. joachim99@2: joachim99@2: GNU GENERAL PUBLIC LICENSE joachim99@2: TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION joachim99@2: joachim99@2: 0. This License applies to any program or other work which contains joachim99@2: a notice placed by the copyright holder saying it may be distributed joachim99@2: under the terms of this General Public License. The "Program", below, joachim99@2: refers to any such program or work, and a "work based on the Program" joachim99@2: means either the Program or any derivative work under copyright law: joachim99@2: that is to say, a work containing the Program or a portion of it, joachim99@2: either verbatim or with modifications and/or translated into another joachim99@2: language. (Hereinafter, translation is included without limitation in joachim99@2: the term "modification".) Each licensee is addressed as "you". joachim99@2: joachim99@2: Activities other than copying, distribution and modification are not joachim99@2: covered by this License; they are outside its scope. The act of joachim99@2: running the Program is not restricted, and the output from the Program joachim99@2: is covered only if its contents constitute a work based on the joachim99@2: Program (independent of having been made by running the Program). joachim99@2: Whether that is true depends on what the Program does. joachim99@2: joachim99@2: 1. You may copy and distribute verbatim copies of the Program's joachim99@2: source code as you receive it, in any medium, provided that you joachim99@2: conspicuously and appropriately publish on each copy an appropriate joachim99@2: copyright notice and disclaimer of warranty; keep intact all the joachim99@2: notices that refer to this License and to the absence of any warranty; joachim99@2: and give any other recipients of the Program a copy of this License joachim99@2: along with the Program. joachim99@2: joachim99@2: You may charge a fee for the physical act of transferring a copy, and joachim99@2: you may at your option offer warranty protection in exchange for a fee. joachim99@2: joachim99@2: 2. You may modify your copy or copies of the Program or any portion joachim99@2: of it, thus forming a work based on the Program, and copy and joachim99@2: distribute such modifications or work under the terms of Section 1 joachim99@2: above, provided that you also meet all of these conditions: joachim99@2: joachim99@2: a) You must cause the modified files to carry prominent notices joachim99@2: stating that you changed the files and the date of any change. joachim99@2: joachim99@2: b) You must cause any work that you distribute or publish, that in joachim99@2: whole or in part contains or is derived from the Program or any joachim99@2: part thereof, to be licensed as a whole at no charge to all third joachim99@2: parties under the terms of this License. joachim99@2: joachim99@2: c) If the modified program normally reads commands interactively joachim99@2: when run, you must cause it, when started running for such joachim99@2: interactive use in the most ordinary way, to print or display an joachim99@2: announcement including an appropriate copyright notice and a joachim99@2: notice that there is no warranty (or else, saying that you provide joachim99@2: a warranty) and that users may redistribute the program under joachim99@2: these conditions, and telling the user how to view a copy of this joachim99@2: License. (Exception: if the Program itself is interactive but joachim99@2: does not normally print such an announcement, your work based on joachim99@2: the Program is not required to print an announcement.) joachim99@2: joachim99@2: These requirements apply to the modified work as a whole. If joachim99@2: identifiable sections of that work are not derived from the Program, joachim99@2: and can be reasonably considered independent and separate works in joachim99@2: themselves, then this License, and its terms, do not apply to those joachim99@2: sections when you distribute them as separate works. But when you joachim99@2: distribute the same sections as part of a whole which is a work based joachim99@2: on the Program, the distribution of the whole must be on the terms of joachim99@2: this License, whose permissions for other licensees extend to the joachim99@2: entire whole, and thus to each and every part regardless of who wrote it. joachim99@2: joachim99@2: Thus, it is not the intent of this section to claim rights or contest joachim99@2: your rights to work written entirely by you; rather, the intent is to joachim99@2: exercise the right to control the distribution of derivative or joachim99@2: collective works based on the Program. joachim99@2: joachim99@2: In addition, mere aggregation of another work not based on the Program joachim99@2: with the Program (or with a work based on the Program) on a volume of joachim99@2: a storage or distribution medium does not bring the other work under joachim99@2: the scope of this License. joachim99@2: joachim99@2: 3. You may copy and distribute the Program (or a work based on it, joachim99@2: under Section 2) in object code or executable form under the terms of joachim99@2: Sections 1 and 2 above provided that you also do one of the following: joachim99@2: joachim99@2: a) Accompany it with the complete corresponding machine-readable joachim99@2: source code, which must be distributed under the terms of Sections joachim99@2: 1 and 2 above on a medium customarily used for software interchange; or, joachim99@2: joachim99@2: b) Accompany it with a written offer, valid for at least three joachim99@2: years, to give any third party, for a charge no more than your joachim99@2: cost of physically performing source distribution, a complete joachim99@2: machine-readable copy of the corresponding source code, to be joachim99@2: distributed under the terms of Sections 1 and 2 above on a medium joachim99@2: customarily used for software interchange; or, joachim99@2: joachim99@2: c) Accompany it with the information you received as to the offer joachim99@2: to distribute corresponding source code. (This alternative is joachim99@2: allowed only for noncommercial distribution and only if you joachim99@2: received the program in object code or executable form with such joachim99@2: an offer, in accord with Subsection b above.) joachim99@2: joachim99@2: The source code for a work means the preferred form of the work for joachim99@2: making modifications to it. For an executable work, complete source joachim99@2: code means all the source code for all modules it contains, plus any joachim99@2: associated interface definition files, plus the scripts used to joachim99@2: control compilation and installation of the executable. However, as a joachim99@2: special exception, the source code distributed need not include joachim99@2: anything that is normally distributed (in either source or binary joachim99@2: form) with the major components (compiler, kernel, and so on) of the joachim99@2: operating system on which the executable runs, unless that component joachim99@2: itself accompanies the executable. joachim99@2: joachim99@2: If distribution of executable or object code is made by offering joachim99@2: access to copy from a designated place, then offering equivalent joachim99@2: access to copy the source code from the same place counts as joachim99@2: distribution of the source code, even though third parties are not joachim99@2: compelled to copy the source along with the object code. joachim99@2: joachim99@2: 4. You may not copy, modify, sublicense, or distribute the Program joachim99@2: except as expressly provided under this License. Any attempt joachim99@2: otherwise to copy, modify, sublicense or distribute the Program is joachim99@2: void, and will automatically terminate your rights under this License. joachim99@2: However, parties who have received copies, or rights, from you under joachim99@2: this License will not have their licenses terminated so long as such joachim99@2: parties remain in full compliance. joachim99@2: joachim99@2: 5. You are not required to accept this License, since you have not joachim99@2: signed it. However, nothing else grants you permission to modify or joachim99@2: distribute the Program or its derivative works. These actions are joachim99@2: prohibited by law if you do not accept this License. Therefore, by joachim99@2: modifying or distributing the Program (or any work based on the joachim99@2: Program), you indicate your acceptance of this License to do so, and joachim99@2: all its terms and conditions for copying, distributing or modifying joachim99@2: the Program or works based on it. joachim99@2: joachim99@2: 6. Each time you redistribute the Program (or any work based on the joachim99@2: Program), the recipient automatically receives a license from the joachim99@2: original licensor to copy, distribute or modify the Program subject to joachim99@2: these terms and conditions. You may not impose any further joachim99@2: restrictions on the recipients' exercise of the rights granted herein. joachim99@2: You are not responsible for enforcing compliance by third parties to joachim99@2: this License. joachim99@2: joachim99@2: 7. If, as a consequence of a court judgment or allegation of patent joachim99@2: infringement or for any other reason (not limited to patent issues), joachim99@2: conditions are imposed on you (whether by court order, agreement or joachim99@2: otherwise) that contradict the conditions of this License, they do not joachim99@2: excuse you from the conditions of this License. If you cannot joachim99@2: distribute so as to satisfy simultaneously your obligations under this joachim99@2: License and any other pertinent obligations, then as a consequence you joachim99@2: may not distribute the Program at all. For example, if a patent joachim99@2: license would not permit royalty-free redistribution of the Program by joachim99@2: all those who receive copies directly or indirectly through you, then joachim99@2: the only way you could satisfy both it and this License would be to joachim99@2: refrain entirely from distribution of the Program. joachim99@2: joachim99@2: If any portion of this section is held invalid or unenforceable under joachim99@2: any particular circumstance, the balance of the section is intended to joachim99@2: apply and the section as a whole is intended to apply in other joachim99@2: circumstances. joachim99@2: joachim99@2: It is not the purpose of this section to induce you to infringe any joachim99@2: patents or other property right claims or to contest validity of any joachim99@2: such claims; this section has the sole purpose of protecting the joachim99@2: integrity of the free software distribution system, which is joachim99@2: implemented by public license practices. Many people have made joachim99@2: generous contributions to the wide range of software distributed joachim99@2: through that system in reliance on consistent application of that joachim99@2: system; it is up to the author/donor to decide if he or she is willing joachim99@2: to distribute software through any other system and a licensee cannot joachim99@2: impose that choice. joachim99@2: joachim99@2: This section is intended to make thoroughly clear what is believed to joachim99@2: be a consequence of the rest of this License. joachim99@2: joachim99@2: 8. If the distribution and/or use of the Program is restricted in joachim99@2: certain countries either by patents or by copyrighted interfaces, the joachim99@2: original copyright holder who places the Program under this License joachim99@2: may add an explicit geographical distribution limitation excluding joachim99@2: those countries, so that distribution is permitted only in or among joachim99@2: countries not thus excluded. In such case, this License incorporates joachim99@2: the limitation as if written in the body of this License. joachim99@2: joachim99@2: 9. The Free Software Foundation may publish revised and/or new versions joachim99@2: of the General Public License from time to time. Such new versions will joachim99@2: be similar in spirit to the present version, but may differ in detail to joachim99@2: address new problems or concerns. joachim99@2: joachim99@2: Each version is given a distinguishing version number. If the Program joachim99@2: specifies a version number of this License which applies to it and "any joachim99@2: later version", you have the option of following the terms and conditions joachim99@2: either of that version or of any later version published by the Free joachim99@2: Software Foundation. If the Program does not specify a version number of joachim99@2: this License, you may choose any version ever published by the Free Software joachim99@2: Foundation. joachim99@2: joachim99@2: 10. If you wish to incorporate parts of the Program into other free joachim99@2: programs whose distribution conditions are different, write to the author joachim99@2: to ask for permission. For software which is copyrighted by the Free joachim99@2: Software Foundation, write to the Free Software Foundation; we sometimes joachim99@2: make exceptions for this. Our decision will be guided by the two goals joachim99@2: of preserving the free status of all derivatives of our free software and joachim99@2: of promoting the sharing and reuse of software generally. joachim99@2: joachim99@2: NO WARRANTY joachim99@2: joachim99@2: 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY joachim99@2: FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN joachim99@2: OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES joachim99@2: PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED joachim99@2: OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF joachim99@2: MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS joachim99@2: TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE joachim99@2: PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, joachim99@2: REPAIR OR CORRECTION. joachim99@2: joachim99@2: 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING joachim99@2: WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR joachim99@2: REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, joachim99@2: INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING joachim99@2: OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED joachim99@2: TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY joachim99@2: YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER joachim99@2: PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE joachim99@2: POSSIBILITY OF SUCH DAMAGES. joachim99@2: joachim99@2: END OF TERMS AND CONDITIONS joachim99@66: joachim99@66: How to Apply These Terms to Your New Programs joachim99@66: joachim99@66: If you develop a new program, and you want it to be of the greatest joachim99@66: possible use to the public, the best way to achieve this is to make it joachim99@66: free software which everyone can redistribute and change under these terms. joachim99@66: joachim99@66: To do so, attach the following notices to the program. It is safest joachim99@66: to attach them to the start of each source file to most effectively joachim99@66: convey the exclusion of warranty; and each file should have at least joachim99@66: the "copyright" line and a pointer to where the full notice is found. joachim99@66: joachim99@66: joachim99@66: Copyright (C) joachim99@66: joachim99@66: This program is free software; you can redistribute it and/or modify joachim99@66: it under the terms of the GNU General Public License as published by joachim99@66: the Free Software Foundation; either version 2 of the License, or joachim99@66: (at your option) any later version. joachim99@66: joachim99@66: This program is distributed in the hope that it will be useful, joachim99@66: but WITHOUT ANY WARRANTY; without even the implied warranty of joachim99@66: MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the joachim99@66: GNU General Public License for more details. joachim99@66: joachim99@66: You should have received a copy of the GNU General Public License joachim99@66: along with this program; if not, write to the Free Software joachim99@66: Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA joachim99@66: joachim99@66: joachim99@66: Also add information on how to contact you by electronic and paper mail. joachim99@66: joachim99@66: If the program is interactive, make it output a short notice like this joachim99@66: when it starts in an interactive mode: joachim99@66: joachim99@66: Gnomovision version 69, Copyright (C) year name of author joachim99@66: Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. joachim99@66: This is free software, and you are welcome to redistribute it joachim99@66: under certain conditions; type `show c' for details. joachim99@66: joachim99@66: The hypothetical commands `show w' and `show c' should show the appropriate joachim99@66: parts of the General Public License. Of course, the commands you use may joachim99@66: be called something other than `show w' and `show c'; they could even be joachim99@66: mouse-clicks or menu items--whatever suits your program. joachim99@66: joachim99@66: You should also get your employer (if you work as a programmer) or your joachim99@66: school, if any, to sign a "copyright disclaimer" for the program, if joachim99@66: necessary. Here is a sample; alter the names: joachim99@66: joachim99@66: Yoyodyne, Inc., hereby disclaims all copyright interest in the program joachim99@66: `Gnomovision' (which makes passes at compilers) written by James Hacker. joachim99@66: joachim99@66: , 1 April 1989 joachim99@66: Ty Coon, President of Vice joachim99@66: joachim99@66: This General Public License does not permit incorporating your program into joachim99@66: proprietary programs. If your program is a subroutine library, you may joachim99@66: consider it more useful to permit linking proprietary applications with the joachim99@66: library. If this is what you want to do, use the GNU Library General joachim99@66: Public License instead of this License.
