p@2550: GNU GENERAL PUBLIC LICENSE p@2550: Version 2, June 1991 p@2550: p@2550: Copyright (C) 1989, 1991 Free Software Foundation, Inc., p@2550: 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA p@2550: Everyone is permitted to copy and distribute verbatim copies p@2550: of this license document, but changing it is not allowed. p@2550: p@2550: Preamble p@2550: p@2550: The licenses for most software are designed to take away your p@2550: freedom to share and change it. By contrast, the GNU General Public p@2550: License is intended to guarantee your freedom to share and change free p@2550: software--to make sure the software is free for all its users. This p@2550: General Public License applies to most of the Free Software p@2550: Foundation's software and to any other program whose authors commit to p@2550: using it. (Some other Free Software Foundation software is covered by p@2550: the GNU Lesser General Public License instead.) You can apply it to p@2550: your programs, too. p@2550: p@2550: When we speak of free software, we are referring to freedom, not p@2550: price. Our General Public Licenses are designed to make sure that you p@2550: have the freedom to distribute copies of free software (and charge for p@2550: this service if you wish), that you receive source code or can get it p@2550: if you want it, that you can change the software or use pieces of it p@2550: in new free programs; and that you know you can do these things. p@2550: p@2550: To protect your rights, we need to make restrictions that forbid p@2550: anyone to deny you these rights or to ask you to surrender the rights. p@2550: These restrictions translate to certain responsibilities for you if you p@2550: distribute copies of the software, or if you modify it. p@2550: p@2550: For example, if you distribute copies of such a program, whether p@2550: gratis or for a fee, you must give the recipients all the rights that p@2550: you have. You must make sure that they, too, receive or can get the p@2550: source code. And you must show them these terms so they know their p@2550: rights. p@2550: p@2550: We protect your rights with two steps: (1) copyright the software, and p@2550: (2) offer you this license which gives you legal permission to copy, p@2550: distribute and/or modify the software. p@2550: p@2550: Also, for each author's protection and ours, we want to make certain p@2550: that everyone understands that there is no warranty for this free p@2550: software. If the software is modified by someone else and passed on, we p@2550: want its recipients to know that what they have is not the original, so p@2550: that any problems introduced by others will not reflect on the original p@2550: authors' reputations. p@2550: p@2550: Finally, any free program is threatened constantly by software p@2550: patents. We wish to avoid the danger that redistributors of a free p@2550: program will individually obtain patent licenses, in effect making the p@2550: program proprietary. To prevent this, we have made it clear that any p@2550: patent must be licensed for everyone's free use or not licensed at all. p@2550: p@2550: The precise terms and conditions for copying, distribution and p@2550: modification follow. p@2550: p@2550: GNU GENERAL PUBLIC LICENSE p@2550: TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION p@2550: p@2550: 0. This License applies to any program or other work which contains p@2550: a notice placed by the copyright holder saying it may be distributed p@2550: under the terms of this General Public License. The "Program", below, p@2550: refers to any such program or work, and a "work based on the Program" p@2550: means either the Program or any derivative work under copyright law: p@2550: that is to say, a work containing the Program or a portion of it, p@2550: either verbatim or with modifications and/or translated into another p@2550: language. (Hereinafter, translation is included without limitation in p@2550: the term "modification".) Each licensee is addressed as "you". p@2550: p@2550: Activities other than copying, distribution and modification are not p@2550: covered by this License; they are outside its scope. The act of p@2550: running the Program is not restricted, and the output from the Program p@2550: is covered only if its contents constitute a work based on the p@2550: Program (independent of having been made by running the Program). p@2550: Whether that is true depends on what the Program does. p@2550: p@2550: 1. You may copy and distribute verbatim copies of the Program's p@2550: source code as you receive it, in any medium, provided that you p@2550: conspicuously and appropriately publish on each copy an appropriate p@2550: copyright notice and disclaimer of warranty; keep intact all the p@2550: notices that refer to this License and to the absence of any warranty; p@2550: and give any other recipients of the Program a copy of this License p@2550: along with the Program. p@2550: p@2550: You may charge a fee for the physical act of transferring a copy, and p@2550: you may at your option offer warranty protection in exchange for a fee. p@2550: p@2550: 2. You may modify your copy or copies of the Program or any portion p@2550: of it, thus forming a work based on the Program, and copy and p@2550: distribute such modifications or work under the terms of Section 1 p@2550: above, provided that you also meet all of these conditions: p@2550: p@2550: a) You must cause the modified files to carry prominent notices p@2550: stating that you changed the files and the date of any change. p@2550: p@2550: b) You must cause any work that you distribute or publish, that in p@2550: whole or in part contains or is derived from the Program or any p@2550: part thereof, to be licensed as a whole at no charge to all third p@2550: parties under the terms of this License. p@2550: p@2550: c) If the modified program normally reads commands interactively p@2550: when run, you must cause it, when started running for such p@2550: interactive use in the most ordinary way, to print or display an p@2550: announcement including an appropriate copyright notice and a p@2550: notice that there is no warranty (or else, saying that you provide p@2550: a warranty) and that users may redistribute the program under p@2550: these conditions, and telling the user how to view a copy of this p@2550: License. (Exception: if the Program itself is interactive but p@2550: does not normally print such an announcement, your work based on p@2550: the Program is not required to print an announcement.) p@2550: p@2550: These requirements apply to the modified work as a whole. If p@2550: identifiable sections of that work are not derived from the Program, p@2550: and can be reasonably considered independent and separate works in p@2550: themselves, then this License, and its terms, do not apply to those p@2550: sections when you distribute them as separate works. But when you p@2550: distribute the same sections as part of a whole which is a work based p@2550: on the Program, the distribution of the whole must be on the terms of p@2550: this License, whose permissions for other licensees extend to the p@2550: entire whole, and thus to each and every part regardless of who wrote it. p@2550: p@2550: Thus, it is not the intent of this section to claim rights or contest p@2550: your rights to work written entirely by you; rather, the intent is to p@2550: exercise the right to control the distribution of derivative or p@2550: collective works based on the Program. p@2550: p@2550: In addition, mere aggregation of another work not based on the Program p@2550: with the Program (or with a work based on the Program) on a volume of p@2550: a storage or distribution medium does not bring the other work under p@2550: the scope of this License. p@2550: p@2550: 3. You may copy and distribute the Program (or a work based on it, p@2550: under Section 2) in object code or executable form under the terms of p@2550: Sections 1 and 2 above provided that you also do one of the following: p@2550: p@2550: a) Accompany it with the complete corresponding machine-readable p@2550: source code, which must be distributed under the terms of Sections p@2550: 1 and 2 above on a medium customarily used for software interchange; or, p@2550: p@2550: b) Accompany it with a written offer, valid for at least three p@2550: years, to give any third party, for a charge no more than your p@2550: cost of physically performing source distribution, a complete p@2550: machine-readable copy of the corresponding source code, to be p@2550: distributed under the terms of Sections 1 and 2 above on a medium p@2550: customarily used for software interchange; or, p@2550: p@2550: c) Accompany it with the information you received as to the offer p@2550: to distribute corresponding source code. (This alternative is p@2550: allowed only for noncommercial distribution and only if you p@2550: received the program in object code or executable form with such p@2550: an offer, in accord with Subsection b above.) p@2550: p@2550: The source code for a work means the preferred form of the work for p@2550: making modifications to it. For an executable work, complete source p@2550: code means all the source code for all modules it contains, plus any p@2550: associated interface definition files, plus the scripts used to p@2550: control compilation and installation of the executable. However, as a p@2550: special exception, the source code distributed need not include p@2550: anything that is normally distributed (in either source or binary p@2550: form) with the major components (compiler, kernel, and so on) of the p@2550: operating system on which the executable runs, unless that component p@2550: itself accompanies the executable. p@2550: p@2550: If distribution of executable or object code is made by offering p@2550: access to copy from a designated place, then offering equivalent p@2550: access to copy the source code from the same place counts as p@2550: distribution of the source code, even though third parties are not p@2550: compelled to copy the source along with the object code. p@2550: p@2550: 4. You may not copy, modify, sublicense, or distribute the Program p@2550: except as expressly provided under this License. Any attempt p@2550: otherwise to copy, modify, sublicense or distribute the Program is p@2550: void, and will automatically terminate your rights under this License. p@2550: However, parties who have received copies, or rights, from you under p@2550: this License will not have their licenses terminated so long as such p@2550: parties remain in full compliance. p@2550: p@2550: 5. You are not required to accept this License, since you have not p@2550: signed it. However, nothing else grants you permission to modify or p@2550: distribute the Program or its derivative works. These actions are p@2550: prohibited by law if you do not accept this License. Therefore, by p@2550: modifying or distributing the Program (or any work based on the p@2550: Program), you indicate your acceptance of this License to do so, and p@2550: all its terms and conditions for copying, distributing or modifying p@2550: the Program or works based on it. p@2550: p@2550: 6. Each time you redistribute the Program (or any work based on the p@2550: Program), the recipient automatically receives a license from the p@2550: original licensor to copy, distribute or modify the Program subject to p@2550: these terms and conditions. You may not impose any further p@2550: restrictions on the recipients' exercise of the rights granted herein. p@2550: You are not responsible for enforcing compliance by third parties to p@2550: this License. p@2550: p@2550: 7. If, as a consequence of a court judgment or allegation of patent p@2550: infringement or for any other reason (not limited to patent issues), p@2550: conditions are imposed on you (whether by court order, agreement or p@2550: otherwise) that contradict the conditions of this License, they do not p@2550: excuse you from the conditions of this License. If you cannot p@2550: distribute so as to satisfy simultaneously your obligations under this p@2550: License and any other pertinent obligations, then as a consequence you p@2550: may not distribute the Program at all. For example, if a patent p@2550: license would not permit royalty-free redistribution of the Program by p@2550: all those who receive copies directly or indirectly through you, then p@2550: the only way you could satisfy both it and this License would be to p@2550: refrain entirely from distribution of the Program. p@2550: p@2550: If any portion of this section is held invalid or unenforceable under p@2550: any particular circumstance, the balance of the section is intended to p@2550: apply and the section as a whole is intended to apply in other p@2550: circumstances. p@2550: p@2550: It is not the purpose of this section to induce you to infringe any p@2550: patents or other property right claims or to contest validity of any p@2550: such claims; this section has the sole purpose of protecting the p@2550: integrity of the free software distribution system, which is p@2550: implemented by public license practices. Many people have made p@2550: generous contributions to the wide range of software distributed p@2550: through that system in reliance on consistent application of that p@2550: system; it is up to the author/donor to decide if he or she is willing p@2550: to distribute software through any other system and a licensee cannot p@2550: impose that choice. p@2550: p@2550: This section is intended to make thoroughly clear what is believed to p@2550: be a consequence of the rest of this License. p@2550: p@2550: 8. If the distribution and/or use of the Program is restricted in p@2550: certain countries either by patents or by copyrighted interfaces, the p@2550: original copyright holder who places the Program under this License p@2550: may add an explicit geographical distribution limitation excluding p@2550: those countries, so that distribution is permitted only in or among p@2550: countries not thus excluded. In such case, this License incorporates p@2550: the limitation as if written in the body of this License. p@2550: p@2550: 9. The Free Software Foundation may publish revised and/or new versions p@2550: of the General Public License from time to time. Such new versions will p@2550: be similar in spirit to the present version, but may differ in detail to p@2550: address new problems or concerns. p@2550: p@2550: Each version is given a distinguishing version number. If the Program p@2550: specifies a version number of this License which applies to it and "any p@2550: later version", you have the option of following the terms and conditions p@2550: either of that version or of any later version published by the Free p@2550: Software Foundation. If the Program does not specify a version number of p@2550: this License, you may choose any version ever published by the Free Software p@2550: Foundation. p@2550: p@2550: 10. If you wish to incorporate parts of the Program into other free p@2550: programs whose distribution conditions are different, write to the author p@2550: to ask for permission. For software which is copyrighted by the Free p@2550: Software Foundation, write to the Free Software Foundation; we sometimes p@2550: make exceptions for this. Our decision will be guided by the two goals p@2550: of preserving the free status of all derivatives of our free software and p@2550: of promoting the sharing and reuse of software generally. p@2550: p@2550: NO WARRANTY p@2550: p@2550: 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY p@2550: FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN p@2550: OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES p@2550: PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED p@2550: OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF p@2550: MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS p@2550: TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE p@2550: PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, p@2550: REPAIR OR CORRECTION. p@2550: p@2550: 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING p@2550: WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR p@2550: REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, p@2550: INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING p@2550: OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED p@2550: TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY p@2550: YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER p@2550: PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE p@2550: POSSIBILITY OF SUCH DAMAGES. p@2550: p@2550: END OF TERMS AND CONDITIONS p@2550: p@2550: How to Apply These Terms to Your New Programs p@2550: p@2550: If you develop a new program, and you want it to be of the greatest p@2550: possible use to the public, the best way to achieve this is to make it p@2550: free software which everyone can redistribute and change under these terms. p@2550: p@2550: To do so, attach the following notices to the program. It is safest p@2550: to attach them to the start of each source file to most effectively p@2550: convey the exclusion of warranty; and each file should have at least p@2550: the "copyright" line and a pointer to where the full notice is found. p@2550: p@2550: p@2550: Copyright (C) p@2550: p@2550: This program is free software; you can redistribute it and/or modify p@2550: it under the terms of the GNU General Public License as published by p@2550: the Free Software Foundation; either version 2 of the License, or p@2550: (at your option) any later version. p@2550: p@2550: This program is distributed in the hope that it will be useful, p@2550: but WITHOUT ANY WARRANTY; without even the implied warranty of p@2550: MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the p@2550: GNU General Public License for more details. p@2550: p@2550: You should have received a copy of the GNU General Public License along p@2550: with this program; if not, write to the Free Software Foundation, Inc., p@2550: 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA. p@2550: p@2550: Also add information on how to contact you by electronic and paper mail. p@2550: p@2550: If the program is interactive, make it output a short notice like this p@2550: when it starts in an interactive mode: p@2550: p@2550: Gnomovision version 69, Copyright (C) year name of author p@2550: Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. p@2550: This is free software, and you are welcome to redistribute it p@2550: under certain conditions; type `show c' for details. p@2550: p@2550: The hypothetical commands `show w' and `show c' should show the appropriate p@2550: parts of the General Public License. Of course, the commands you use may p@2550: be called something other than `show w' and `show c'; they could even be p@2550: mouse-clicks or menu items--whatever suits your program. p@2550: p@2550: You should also get your employer (if you work as a programmer) or your p@2550: school, if any, to sign a "copyright disclaimer" for the program, if p@2550: necessary. Here is a sample; alter the names: p@2550: p@2550: Yoyodyne, Inc., hereby disclaims all copyright interest in the program p@2550: `Gnomovision' (which makes passes at compilers) written by James Hacker. p@2550: p@2550: , 1 April 1989 p@2550: Ty Coon, President of Vice p@2550: p@2550: This General Public License does not permit incorporating your program into p@2550: proprietary programs. If your program is a subroutine library, you may p@2550: consider it more useful to permit linking proprietary applications with the p@2550: library. If this is what you want to do, use the GNU Lesser General p@2550: Public License instead of this License.
