terom@280: GNU GENERAL PUBLIC LICENSE terom@280: Version 2, June 1991 terom@280: terom@280: Copyright (C) 1989, 1991 Free Software Foundation, Inc., terom@280: 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA terom@280: Everyone is permitted to copy and distribute verbatim copies terom@280: of this license document, but changing it is not allowed. terom@280: terom@280: Preamble terom@280: terom@280: The licenses for most software are designed to take away your terom@280: freedom to share and change it. By contrast, the GNU General Public terom@280: License is intended to guarantee your freedom to share and change free terom@280: software--to make sure the software is free for all its users. This terom@280: General Public License applies to most of the Free Software terom@280: Foundation's software and to any other program whose authors commit to terom@280: using it. (Some other Free Software Foundation software is covered by terom@280: the GNU Lesser General Public License instead.) You can apply it to terom@280: your programs, too. terom@280: terom@280: When we speak of free software, we are referring to freedom, not terom@280: price. Our General Public Licenses are designed to make sure that you terom@280: have the freedom to distribute copies of free software (and charge for terom@280: this service if you wish), that you receive source code or can get it terom@280: if you want it, that you can change the software or use pieces of it terom@280: in new free programs; and that you know you can do these things. terom@280: terom@280: To protect your rights, we need to make restrictions that forbid terom@280: anyone to deny you these rights or to ask you to surrender the rights. terom@280: These restrictions translate to certain responsibilities for you if you terom@280: distribute copies of the software, or if you modify it. terom@280: terom@280: For example, if you distribute copies of such a program, whether terom@280: gratis or for a fee, you must give the recipients all the rights that terom@280: you have. You must make sure that they, too, receive or can get the terom@280: source code. And you must show them these terms so they know their terom@280: rights. terom@280: terom@280: We protect your rights with two steps: (1) copyright the software, and terom@280: (2) offer you this license which gives you legal permission to copy, terom@280: distribute and/or modify the software. terom@280: terom@280: Also, for each author's protection and ours, we want to make certain terom@280: that everyone understands that there is no warranty for this free terom@280: software. If the software is modified by someone else and passed on, we terom@280: want its recipients to know that what they have is not the original, so terom@280: that any problems introduced by others will not reflect on the original terom@280: authors' reputations. terom@280: terom@280: Finally, any free program is threatened constantly by software terom@280: patents. We wish to avoid the danger that redistributors of a free terom@280: program will individually obtain patent licenses, in effect making the terom@280: program proprietary. To prevent this, we have made it clear that any terom@280: patent must be licensed for everyone's free use or not licensed at all. terom@280: terom@280: The precise terms and conditions for copying, distribution and terom@280: modification follow. terom@280: terom@280: GNU GENERAL PUBLIC LICENSE terom@280: TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION terom@280: terom@280: 0. This License applies to any program or other work which contains terom@280: a notice placed by the copyright holder saying it may be distributed terom@280: under the terms of this General Public License. The "Program", below, terom@280: refers to any such program or work, and a "work based on the Program" terom@280: means either the Program or any derivative work under copyright law: terom@280: that is to say, a work containing the Program or a portion of it, terom@280: either verbatim or with modifications and/or translated into another terom@280: language. (Hereinafter, translation is included without limitation in terom@280: the term "modification".) Each licensee is addressed as "you". terom@280: terom@280: Activities other than copying, distribution and modification are not terom@280: covered by this License; they are outside its scope. The act of terom@280: running the Program is not restricted, and the output from the Program terom@280: is covered only if its contents constitute a work based on the terom@280: Program (independent of having been made by running the Program). terom@280: Whether that is true depends on what the Program does. terom@280: terom@280: 1. You may copy and distribute verbatim copies of the Program's terom@280: source code as you receive it, in any medium, provided that you terom@280: conspicuously and appropriately publish on each copy an appropriate terom@280: copyright notice and disclaimer of warranty; keep intact all the terom@280: notices that refer to this License and to the absence of any warranty; terom@280: and give any other recipients of the Program a copy of this License terom@280: along with the Program. terom@280: terom@280: You may charge a fee for the physical act of transferring a copy, and terom@280: you may at your option offer warranty protection in exchange for a fee. terom@280: terom@280: 2. You may modify your copy or copies of the Program or any portion terom@280: of it, thus forming a work based on the Program, and copy and terom@280: distribute such modifications or work under the terms of Section 1 terom@280: above, provided that you also meet all of these conditions: terom@280: terom@280: a) You must cause the modified files to carry prominent notices terom@280: stating that you changed the files and the date of any change. terom@280: terom@280: b) You must cause any work that you distribute or publish, that in terom@280: whole or in part contains or is derived from the Program or any terom@280: part thereof, to be licensed as a whole at no charge to all third terom@280: parties under the terms of this License. terom@280: terom@280: c) If the modified program normally reads commands interactively terom@280: when run, you must cause it, when started running for such terom@280: interactive use in the most ordinary way, to print or display an terom@280: announcement including an appropriate copyright notice and a terom@280: notice that there is no warranty (or else, saying that you provide terom@280: a warranty) and that users may redistribute the program under terom@280: these conditions, and telling the user how to view a copy of this terom@280: License. (Exception: if the Program itself is interactive but terom@280: does not normally print such an announcement, your work based on terom@280: the Program is not required to print an announcement.) terom@280: terom@280: These requirements apply to the modified work as a whole. If terom@280: identifiable sections of that work are not derived from the Program, terom@280: and can be reasonably considered independent and separate works in terom@280: themselves, then this License, and its terms, do not apply to those terom@280: sections when you distribute them as separate works. But when you terom@280: distribute the same sections as part of a whole which is a work based terom@280: on the Program, the distribution of the whole must be on the terms of terom@280: this License, whose permissions for other licensees extend to the terom@280: entire whole, and thus to each and every part regardless of who wrote it. terom@280: terom@280: Thus, it is not the intent of this section to claim rights or contest terom@280: your rights to work written entirely by you; rather, the intent is to terom@280: exercise the right to control the distribution of derivative or terom@280: collective works based on the Program. terom@280: terom@280: In addition, mere aggregation of another work not based on the Program terom@280: with the Program (or with a work based on the Program) on a volume of terom@280: a storage or distribution medium does not bring the other work under terom@280: the scope of this License. terom@280: terom@280: 3. You may copy and distribute the Program (or a work based on it, terom@280: under Section 2) in object code or executable form under the terms of terom@280: Sections 1 and 2 above provided that you also do one of the following: terom@280: terom@280: a) Accompany it with the complete corresponding machine-readable terom@280: source code, which must be distributed under the terms of Sections terom@280: 1 and 2 above on a medium customarily used for software interchange; or, terom@280: terom@280: b) Accompany it with a written offer, valid for at least three terom@280: years, to give any third party, for a charge no more than your terom@280: cost of physically performing source distribution, a complete terom@280: machine-readable copy of the corresponding source code, to be terom@280: distributed under the terms of Sections 1 and 2 above on a medium terom@280: customarily used for software interchange; or, terom@280: terom@280: c) Accompany it with the information you received as to the offer terom@280: to distribute corresponding source code. (This alternative is terom@280: allowed only for noncommercial distribution and only if you terom@280: received the program in object code or executable form with such terom@280: an offer, in accord with Subsection b above.) terom@280: terom@280: The source code for a work means the preferred form of the work for terom@280: making modifications to it. For an executable work, complete source terom@280: code means all the source code for all modules it contains, plus any terom@280: associated interface definition files, plus the scripts used to terom@280: control compilation and installation of the executable. However, as a terom@280: special exception, the source code distributed need not include terom@280: anything that is normally distributed (in either source or binary terom@280: form) with the major components (compiler, kernel, and so on) of the terom@280: operating system on which the executable runs, unless that component terom@280: itself accompanies the executable. terom@280: terom@280: If distribution of executable or object code is made by offering terom@280: access to copy from a designated place, then offering equivalent terom@280: access to copy the source code from the same place counts as terom@280: distribution of the source code, even though third parties are not terom@280: compelled to copy the source along with the object code. terom@280: terom@280: 4. You may not copy, modify, sublicense, or distribute the Program terom@280: except as expressly provided under this License. Any attempt terom@280: otherwise to copy, modify, sublicense or distribute the Program is terom@280: void, and will automatically terminate your rights under this License. terom@280: However, parties who have received copies, or rights, from you under terom@280: this License will not have their licenses terminated so long as such terom@280: parties remain in full compliance. terom@280: terom@280: 5. You are not required to accept this License, since you have not terom@280: signed it. However, nothing else grants you permission to modify or terom@280: distribute the Program or its derivative works. These actions are terom@280: prohibited by law if you do not accept this License. Therefore, by terom@280: modifying or distributing the Program (or any work based on the terom@280: Program), you indicate your acceptance of this License to do so, and terom@280: all its terms and conditions for copying, distributing or modifying terom@280: the Program or works based on it. terom@280: terom@280: 6. Each time you redistribute the Program (or any work based on the terom@280: Program), the recipient automatically receives a license from the terom@280: original licensor to copy, distribute or modify the Program subject to terom@280: these terms and conditions. You may not impose any further terom@280: restrictions on the recipients' exercise of the rights granted herein. terom@280: You are not responsible for enforcing compliance by third parties to terom@280: this License. terom@280: terom@280: 7. If, as a consequence of a court judgment or allegation of patent terom@280: infringement or for any other reason (not limited to patent issues), terom@280: conditions are imposed on you (whether by court order, agreement or terom@280: otherwise) that contradict the conditions of this License, they do not terom@280: excuse you from the conditions of this License. If you cannot terom@280: distribute so as to satisfy simultaneously your obligations under this terom@280: License and any other pertinent obligations, then as a consequence you terom@280: may not distribute the Program at all. For example, if a patent terom@280: license would not permit royalty-free redistribution of the Program by terom@280: all those who receive copies directly or indirectly through you, then terom@280: the only way you could satisfy both it and this License would be to terom@280: refrain entirely from distribution of the Program. terom@280: terom@280: If any portion of this section is held invalid or unenforceable under terom@280: any particular circumstance, the balance of the section is intended to terom@280: apply and the section as a whole is intended to apply in other terom@280: circumstances. terom@280: terom@280: It is not the purpose of this section to induce you to infringe any terom@280: patents or other property right claims or to contest validity of any terom@280: such claims; this section has the sole purpose of protecting the terom@280: integrity of the free software distribution system, which is terom@280: implemented by public license practices. Many people have made terom@280: generous contributions to the wide range of software distributed terom@280: through that system in reliance on consistent application of that terom@280: system; it is up to the author/donor to decide if he or she is willing terom@280: to distribute software through any other system and a licensee cannot terom@280: impose that choice. terom@280: terom@280: This section is intended to make thoroughly clear what is believed to terom@280: be a consequence of the rest of this License. terom@280: terom@280: 8. If the distribution and/or use of the Program is restricted in terom@280: certain countries either by patents or by copyrighted interfaces, the terom@280: original copyright holder who places the Program under this License terom@280: may add an explicit geographical distribution limitation excluding terom@280: those countries, so that distribution is permitted only in or among terom@280: countries not thus excluded. In such case, this License incorporates terom@280: the limitation as if written in the body of this License. terom@280: terom@280: 9. The Free Software Foundation may publish revised and/or new versions terom@280: of the General Public License from time to time. Such new versions will terom@280: be similar in spirit to the present version, but may differ in detail to terom@280: address new problems or concerns. terom@280: terom@280: Each version is given a distinguishing version number. If the Program terom@280: specifies a version number of this License which applies to it and "any terom@280: later version", you have the option of following the terms and conditions terom@280: either of that version or of any later version published by the Free terom@280: Software Foundation. If the Program does not specify a version number of terom@280: this License, you may choose any version ever published by the Free Software terom@280: Foundation. terom@280: terom@280: 10. If you wish to incorporate parts of the Program into other free terom@280: programs whose distribution conditions are different, write to the author terom@280: to ask for permission. For software which is copyrighted by the Free terom@280: Software Foundation, write to the Free Software Foundation; we sometimes terom@280: make exceptions for this. Our decision will be guided by the two goals terom@280: of preserving the free status of all derivatives of our free software and terom@280: of promoting the sharing and reuse of software generally. terom@280: terom@280: NO WARRANTY terom@280: terom@280: 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY terom@280: FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN terom@280: OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES terom@280: PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED terom@280: OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF terom@280: MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS terom@280: TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE terom@280: PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, terom@280: REPAIR OR CORRECTION. terom@280: terom@280: 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING terom@280: WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR terom@280: REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, terom@280: INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING terom@280: OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED terom@280: TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY terom@280: YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER terom@280: PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE terom@280: POSSIBILITY OF SUCH DAMAGES. terom@280: terom@280: END OF TERMS AND CONDITIONS terom@280: terom@280: How to Apply These Terms to Your New Programs terom@280: terom@280: If you develop a new program, and you want it to be of the greatest terom@280: possible use to the public, the best way to achieve this is to make it terom@280: free software which everyone can redistribute and change under these terms. terom@280: terom@280: To do so, attach the following notices to the program. It is safest terom@280: to attach them to the start of each source file to most effectively terom@280: convey the exclusion of warranty; and each file should have at least terom@280: the "copyright" line and a pointer to where the full notice is found. terom@280: terom@280: terom@280: Copyright (C) terom@280: terom@280: This program is free software; you can redistribute it and/or modify terom@280: it under the terms of the GNU General Public License as published by terom@280: the Free Software Foundation; either version 2 of the License, or terom@280: (at your option) any later version. terom@280: terom@280: This program is distributed in the hope that it will be useful, terom@280: but WITHOUT ANY WARRANTY; without even the implied warranty of terom@280: MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the terom@280: GNU General Public License for more details. terom@280: terom@280: You should have received a copy of the GNU General Public License along terom@280: with this program; if not, write to the Free Software Foundation, Inc., terom@280: 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA. terom@280: terom@280: Also add information on how to contact you by electronic and paper mail. terom@280: terom@280: If the program is interactive, make it output a short notice like this terom@280: when it starts in an interactive mode: terom@280: terom@280: Gnomovision version 69, Copyright (C) year name of author terom@280: Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. terom@280: This is free software, and you are welcome to redistribute it terom@280: under certain conditions; type `show c' for details. terom@280: terom@280: The hypothetical commands `show w' and `show c' should show the appropriate terom@280: parts of the General Public License. Of course, the commands you use may terom@280: be called something other than `show w' and `show c'; they could even be terom@280: mouse-clicks or menu items--whatever suits your program. terom@280: terom@280: You should also get your employer (if you work as a programmer) or your terom@280: school, if any, to sign a "copyright disclaimer" for the program, if terom@280: necessary. Here is a sample; alter the names: terom@280: terom@280: Yoyodyne, Inc., hereby disclaims all copyright interest in the program terom@280: `Gnomovision' (which makes passes at compilers) written by James Hacker. terom@280: terom@280: , 1 April 1989 terom@280: Ty Coon, President of Vice terom@280: terom@280: This General Public License does not permit incorporating your program into terom@280: proprietary programs. If your program is a subroutine library, you may terom@280: consider it more useful to permit linking proprietary applications with the terom@280: library. If this is what you want to do, use the GNU Lesser General terom@280: Public License instead of this License.
