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