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