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