c@310: GNU GENERAL PUBLIC LICENSE c@310: Version 2, June 1991 c@310: c@310: Copyright (C) 1989, 1991 Free Software Foundation, Inc. cannam@513: 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA c@310: Everyone is permitted to copy and distribute verbatim copies c@310: of this license document, but changing it is not allowed. c@310: c@310: Preamble c@310: c@310: The licenses for most software are designed to take away your c@310: freedom to share and change it. By contrast, the GNU General Public c@310: License is intended to guarantee your freedom to share and change free c@310: software--to make sure the software is free for all its users. This c@310: General Public License applies to most of the Free Software c@310: Foundation's software and to any other program whose authors commit to c@310: using it. (Some other Free Software Foundation software is covered by c@310: the GNU Library General Public License instead.) You can apply it to c@310: your programs, too. c@310: c@310: When we speak of free software, we are referring to freedom, not c@310: price. Our General Public Licenses are designed to make sure that you c@310: have the freedom to distribute copies of free software (and charge for c@310: this service if you wish), that you receive source code or can get it c@310: if you want it, that you can change the software or use pieces of it c@310: in new free programs; and that you know you can do these things. c@310: c@310: To protect your rights, we need to make restrictions that forbid c@310: anyone to deny you these rights or to ask you to surrender the rights. c@310: These restrictions translate to certain responsibilities for you if you c@310: distribute copies of the software, or if you modify it. c@310: c@310: For example, if you distribute copies of such a program, whether c@310: gratis or for a fee, you must give the recipients all the rights that c@310: you have. You must make sure that they, too, receive or can get the c@310: source code. And you must show them these terms so they know their c@310: rights. c@310: c@310: We protect your rights with two steps: (1) copyright the software, and c@310: (2) offer you this license which gives you legal permission to copy, c@310: distribute and/or modify the software. c@310: c@310: Also, for each author's protection and ours, we want to make certain c@310: that everyone understands that there is no warranty for this free c@310: software. If the software is modified by someone else and passed on, we c@310: want its recipients to know that what they have is not the original, so c@310: that any problems introduced by others will not reflect on the original c@310: authors' reputations. c@310: c@310: Finally, any free program is threatened constantly by software c@310: patents. We wish to avoid the danger that redistributors of a free c@310: program will individually obtain patent licenses, in effect making the c@310: program proprietary. To prevent this, we have made it clear that any c@310: patent must be licensed for everyone's free use or not licensed at all. c@310: c@310: The precise terms and conditions for copying, distribution and c@310: modification follow. c@310: c@310: GNU GENERAL PUBLIC LICENSE c@310: TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION c@310: c@310: 0. This License applies to any program or other work which contains c@310: a notice placed by the copyright holder saying it may be distributed c@310: under the terms of this General Public License. The "Program", below, c@310: refers to any such program or work, and a "work based on the Program" c@310: means either the Program or any derivative work under copyright law: c@310: that is to say, a work containing the Program or a portion of it, c@310: either verbatim or with modifications and/or translated into another c@310: language. (Hereinafter, translation is included without limitation in c@310: the term "modification".) Each licensee is addressed as "you". c@310: c@310: Activities other than copying, distribution and modification are not c@310: covered by this License; they are outside its scope. The act of c@310: running the Program is not restricted, and the output from the Program c@310: is covered only if its contents constitute a work based on the c@310: Program (independent of having been made by running the Program). c@310: Whether that is true depends on what the Program does. c@310: c@310: 1. You may copy and distribute verbatim copies of the Program's c@310: source code as you receive it, in any medium, provided that you c@310: conspicuously and appropriately publish on each copy an appropriate c@310: copyright notice and disclaimer of warranty; keep intact all the c@310: notices that refer to this License and to the absence of any warranty; c@310: and give any other recipients of the Program a copy of this License c@310: along with the Program. c@310: c@310: You may charge a fee for the physical act of transferring a copy, and c@310: you may at your option offer warranty protection in exchange for a fee. c@310: c@310: 2. You may modify your copy or copies of the Program or any portion c@310: of it, thus forming a work based on the Program, and copy and c@310: distribute such modifications or work under the terms of Section 1 c@310: above, provided that you also meet all of these conditions: c@310: c@310: a) You must cause the modified files to carry prominent notices c@310: stating that you changed the files and the date of any change. c@310: c@310: b) You must cause any work that you distribute or publish, that in c@310: whole or in part contains or is derived from the Program or any c@310: part thereof, to be licensed as a whole at no charge to all third c@310: parties under the terms of this License. c@310: c@310: c) If the modified program normally reads commands interactively c@310: when run, you must cause it, when started running for such c@310: interactive use in the most ordinary way, to print or display an c@310: announcement including an appropriate copyright notice and a c@310: notice that there is no warranty (or else, saying that you provide c@310: a warranty) and that users may redistribute the program under c@310: these conditions, and telling the user how to view a copy of this c@310: License. (Exception: if the Program itself is interactive but c@310: does not normally print such an announcement, your work based on c@310: the Program is not required to print an announcement.) c@310: c@310: These requirements apply to the modified work as a whole. If c@310: identifiable sections of that work are not derived from the Program, c@310: and can be reasonably considered independent and separate works in c@310: themselves, then this License, and its terms, do not apply to those c@310: sections when you distribute them as separate works. But when you c@310: distribute the same sections as part of a whole which is a work based c@310: on the Program, the distribution of the whole must be on the terms of c@310: this License, whose permissions for other licensees extend to the c@310: entire whole, and thus to each and every part regardless of who wrote it. c@310: c@310: Thus, it is not the intent of this section to claim rights or contest c@310: your rights to work written entirely by you; rather, the intent is to c@310: exercise the right to control the distribution of derivative or c@310: collective works based on the Program. c@310: c@310: In addition, mere aggregation of another work not based on the Program c@310: with the Program (or with a work based on the Program) on a volume of c@310: a storage or distribution medium does not bring the other work under c@310: the scope of this License. c@310: c@310: 3. You may copy and distribute the Program (or a work based on it, c@310: under Section 2) in object code or executable form under the terms of c@310: Sections 1 and 2 above provided that you also do one of the following: c@310: c@310: a) Accompany it with the complete corresponding machine-readable c@310: source code, which must be distributed under the terms of Sections c@310: 1 and 2 above on a medium customarily used for software interchange; or, c@310: c@310: b) Accompany it with a written offer, valid for at least three c@310: years, to give any third party, for a charge no more than your c@310: cost of physically performing source distribution, a complete c@310: machine-readable copy of the corresponding source code, to be c@310: distributed under the terms of Sections 1 and 2 above on a medium c@310: customarily used for software interchange; or, c@310: c@310: c) Accompany it with the information you received as to the offer c@310: to distribute corresponding source code. (This alternative is c@310: allowed only for noncommercial distribution and only if you c@310: received the program in object code or executable form with such c@310: an offer, in accord with Subsection b above.) c@310: c@310: The source code for a work means the preferred form of the work for c@310: making modifications to it. For an executable work, complete source c@310: code means all the source code for all modules it contains, plus any c@310: associated interface definition files, plus the scripts used to c@310: control compilation and installation of the executable. However, as a c@310: special exception, the source code distributed need not include c@310: anything that is normally distributed (in either source or binary c@310: form) with the major components (compiler, kernel, and so on) of the c@310: operating system on which the executable runs, unless that component c@310: itself accompanies the executable. c@310: c@310: If distribution of executable or object code is made by offering c@310: access to copy from a designated place, then offering equivalent c@310: access to copy the source code from the same place counts as c@310: distribution of the source code, even though third parties are not c@310: compelled to copy the source along with the object code. c@310: c@310: 4. You may not copy, modify, sublicense, or distribute the Program c@310: except as expressly provided under this License. Any attempt c@310: otherwise to copy, modify, sublicense or distribute the Program is c@310: void, and will automatically terminate your rights under this License. c@310: However, parties who have received copies, or rights, from you under c@310: this License will not have their licenses terminated so long as such c@310: parties remain in full compliance. c@310: c@310: 5. You are not required to accept this License, since you have not c@310: signed it. However, nothing else grants you permission to modify or c@310: distribute the Program or its derivative works. These actions are c@310: prohibited by law if you do not accept this License. Therefore, by c@310: modifying or distributing the Program (or any work based on the c@310: Program), you indicate your acceptance of this License to do so, and c@310: all its terms and conditions for copying, distributing or modifying c@310: the Program or works based on it. c@310: c@310: 6. Each time you redistribute the Program (or any work based on the c@310: Program), the recipient automatically receives a license from the c@310: original licensor to copy, distribute or modify the Program subject to c@310: these terms and conditions. You may not impose any further c@310: restrictions on the recipients' exercise of the rights granted herein. c@310: You are not responsible for enforcing compliance by third parties to c@310: this License. c@310: c@310: 7. If, as a consequence of a court judgment or allegation of patent c@310: infringement or for any other reason (not limited to patent issues), c@310: conditions are imposed on you (whether by court order, agreement or c@310: otherwise) that contradict the conditions of this License, they do not c@310: excuse you from the conditions of this License. If you cannot c@310: distribute so as to satisfy simultaneously your obligations under this c@310: License and any other pertinent obligations, then as a consequence you c@310: may not distribute the Program at all. For example, if a patent c@310: license would not permit royalty-free redistribution of the Program by c@310: all those who receive copies directly or indirectly through you, then c@310: the only way you could satisfy both it and this License would be to c@310: refrain entirely from distribution of the Program. c@310: c@310: If any portion of this section is held invalid or unenforceable under c@310: any particular circumstance, the balance of the section is intended to c@310: apply and the section as a whole is intended to apply in other c@310: circumstances. c@310: c@310: It is not the purpose of this section to induce you to infringe any c@310: patents or other property right claims or to contest validity of any c@310: such claims; this section has the sole purpose of protecting the c@310: integrity of the free software distribution system, which is c@310: implemented by public license practices. Many people have made c@310: generous contributions to the wide range of software distributed c@310: through that system in reliance on consistent application of that c@310: system; it is up to the author/donor to decide if he or she is willing c@310: to distribute software through any other system and a licensee cannot c@310: impose that choice. c@310: c@310: This section is intended to make thoroughly clear what is believed to c@310: be a consequence of the rest of this License. c@310: c@310: 8. If the distribution and/or use of the Program is restricted in c@310: certain countries either by patents or by copyrighted interfaces, the c@310: original copyright holder who places the Program under this License c@310: may add an explicit geographical distribution limitation excluding c@310: those countries, so that distribution is permitted only in or among c@310: countries not thus excluded. In such case, this License incorporates c@310: the limitation as if written in the body of this License. c@310: c@310: 9. The Free Software Foundation may publish revised and/or new versions c@310: of the General Public License from time to time. Such new versions will c@310: be similar in spirit to the present version, but may differ in detail to c@310: address new problems or concerns. c@310: c@310: Each version is given a distinguishing version number. If the Program c@310: specifies a version number of this License which applies to it and "any c@310: later version", you have the option of following the terms and conditions c@310: either of that version or of any later version published by the Free c@310: Software Foundation. If the Program does not specify a version number of c@310: this License, you may choose any version ever published by the Free Software c@310: Foundation. c@310: c@310: 10. If you wish to incorporate parts of the Program into other free c@310: programs whose distribution conditions are different, write to the author c@310: to ask for permission. For software which is copyrighted by the Free c@310: Software Foundation, write to the Free Software Foundation; we sometimes c@310: make exceptions for this. Our decision will be guided by the two goals c@310: of preserving the free status of all derivatives of our free software and c@310: of promoting the sharing and reuse of software generally. c@310: c@310: NO WARRANTY c@310: c@310: 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY c@310: FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN c@310: OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES c@310: PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED c@310: OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF c@310: MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS c@310: TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE c@310: PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, c@310: REPAIR OR CORRECTION. c@310: c@310: 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING c@310: WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR c@310: REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, c@310: INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING c@310: OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED c@310: TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY c@310: YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER c@310: PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE c@310: POSSIBILITY OF SUCH DAMAGES. c@310: c@310: END OF TERMS AND CONDITIONS
