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