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