melunko@249: GNU GENERAL PUBLIC LICENSE melunko@249: Version 2, June 1991 melunko@249: melunko@249: Copyright (C) 1989, 1991 Free Software Foundation, Inc. melunko@249: 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA melunko@249: Everyone is permitted to copy and distribute verbatim copies melunko@249: of this license document, but changing it is not allowed. melunko@249: melunko@249: Preamble melunko@249: melunko@249: The licenses for most software are designed to take away your melunko@249: freedom to share and change it. By contrast, the GNU General Public melunko@249: License is intended to guarantee your freedom to share and change free melunko@249: software--to make sure the software is free for all its users. This melunko@249: General Public License applies to most of the Free Software melunko@249: Foundation's software and to any other program whose authors commit to melunko@249: using it. (Some other Free Software Foundation software is covered by melunko@249: the GNU Library General Public License instead.) You can apply it to melunko@249: your programs, too. melunko@249: melunko@249: When we speak of free software, we are referring to freedom, not melunko@249: price. Our General Public Licenses are designed to make sure that you melunko@249: have the freedom to distribute copies of free software (and charge for melunko@249: this service if you wish), that you receive source code or can get it melunko@249: if you want it, that you can change the software or use pieces of it melunko@249: in new free programs; and that you know you can do these things. melunko@249: melunko@249: To protect your rights, we need to make restrictions that forbid melunko@249: anyone to deny you these rights or to ask you to surrender the rights. melunko@249: These restrictions translate to certain responsibilities for you if you melunko@249: distribute copies of the software, or if you modify it. melunko@249: melunko@249: For example, if you distribute copies of such a program, whether melunko@249: gratis or for a fee, you must give the recipients all the rights that melunko@249: you have. You must make sure that they, too, receive or can get the melunko@249: source code. And you must show them these terms so they know their melunko@249: rights. melunko@249: melunko@249: We protect your rights with two steps: (1) copyright the software, and melunko@249: (2) offer you this license which gives you legal permission to copy, melunko@249: distribute and/or modify the software. melunko@249: melunko@249: Also, for each author's protection and ours, we want to make certain melunko@249: that everyone understands that there is no warranty for this free melunko@249: software. If the software is modified by someone else and passed on, we melunko@249: want its recipients to know that what they have is not the original, so melunko@249: that any problems introduced by others will not reflect on the original melunko@249: authors' reputations. melunko@249: melunko@249: Finally, any free program is threatened constantly by software melunko@249: patents. We wish to avoid the danger that redistributors of a free melunko@249: program will individually obtain patent licenses, in effect making the melunko@249: program proprietary. To prevent this, we have made it clear that any melunko@249: patent must be licensed for everyone's free use or not licensed at all. melunko@249: melunko@249: The precise terms and conditions for copying, distribution and melunko@249: modification follow. melunko@249: melunko@249: GNU GENERAL PUBLIC LICENSE melunko@249: TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION melunko@249: melunko@249: 0. This License applies to any program or other work which contains melunko@249: a notice placed by the copyright holder saying it may be distributed melunko@249: under the terms of this General Public License. The "Program", below, melunko@249: refers to any such program or work, and a "work based on the Program" melunko@249: means either the Program or any derivative work under copyright law: melunko@249: that is to say, a work containing the Program or a portion of it, melunko@249: either verbatim or with modifications and/or translated into another melunko@249: language. (Hereinafter, translation is included without limitation in melunko@249: the term "modification".) Each licensee is addressed as "you". melunko@249: melunko@249: Activities other than copying, distribution and modification are not melunko@249: covered by this License; they are outside its scope. The act of melunko@249: running the Program is not restricted, and the output from the Program melunko@249: is covered only if its contents constitute a work based on the melunko@249: Program (independent of having been made by running the Program). melunko@249: Whether that is true depends on what the Program does. melunko@249: melunko@249: 1. You may copy and distribute verbatim copies of the Program's melunko@249: source code as you receive it, in any medium, provided that you melunko@249: conspicuously and appropriately publish on each copy an appropriate melunko@249: copyright notice and disclaimer of warranty; keep intact all the melunko@249: notices that refer to this License and to the absence of any warranty; melunko@249: and give any other recipients of the Program a copy of this License melunko@249: along with the Program. melunko@249: melunko@249: You may charge a fee for the physical act of transferring a copy, and melunko@249: you may at your option offer warranty protection in exchange for a fee. melunko@249: melunko@249: 2. You may modify your copy or copies of the Program or any portion melunko@249: of it, thus forming a work based on the Program, and copy and melunko@249: distribute such modifications or work under the terms of Section 1 melunko@249: above, provided that you also meet all of these conditions: melunko@249: melunko@249: a) You must cause the modified files to carry prominent notices melunko@249: stating that you changed the files and the date of any change. melunko@249: melunko@249: b) You must cause any work that you distribute or publish, that in melunko@249: whole or in part contains or is derived from the Program or any melunko@249: part thereof, to be licensed as a whole at no charge to all third melunko@249: parties under the terms of this License. melunko@249: melunko@249: c) If the modified program normally reads commands interactively melunko@249: when run, you must cause it, when started running for such melunko@249: interactive use in the most ordinary way, to print or display an melunko@249: announcement including an appropriate copyright notice and a melunko@249: notice that there is no warranty (or else, saying that you provide melunko@249: a warranty) and that users may redistribute the program under melunko@249: these conditions, and telling the user how to view a copy of this melunko@249: License. (Exception: if the Program itself is interactive but melunko@249: does not normally print such an announcement, your work based on melunko@249: the Program is not required to print an announcement.) melunko@249: melunko@249: These requirements apply to the modified work as a whole. If melunko@249: identifiable sections of that work are not derived from the Program, melunko@249: and can be reasonably considered independent and separate works in melunko@249: themselves, then this License, and its terms, do not apply to those melunko@249: sections when you distribute them as separate works. But when you melunko@249: distribute the same sections as part of a whole which is a work based melunko@249: on the Program, the distribution of the whole must be on the terms of melunko@249: this License, whose permissions for other licensees extend to the melunko@249: entire whole, and thus to each and every part regardless of who wrote it. melunko@249: melunko@249: Thus, it is not the intent of this section to claim rights or contest melunko@249: your rights to work written entirely by you; rather, the intent is to melunko@249: exercise the right to control the distribution of derivative or melunko@249: collective works based on the Program. melunko@249: melunko@249: In addition, mere aggregation of another work not based on the Program melunko@249: with the Program (or with a work based on the Program) on a volume of melunko@249: a storage or distribution medium does not bring the other work under melunko@249: the scope of this License. melunko@249: melunko@249: 3. You may copy and distribute the Program (or a work based on it, melunko@249: under Section 2) in object code or executable form under the terms of melunko@249: Sections 1 and 2 above provided that you also do one of the following: melunko@249: melunko@249: a) Accompany it with the complete corresponding machine-readable melunko@249: source code, which must be distributed under the terms of Sections melunko@249: 1 and 2 above on a medium customarily used for software interchange; or, melunko@249: melunko@249: b) Accompany it with a written offer, valid for at least three melunko@249: years, to give any third party, for a charge no more than your melunko@249: cost of physically performing source distribution, a complete melunko@249: machine-readable copy of the corresponding source code, to be melunko@249: distributed under the terms of Sections 1 and 2 above on a medium melunko@249: customarily used for software interchange; or, melunko@249: melunko@249: c) Accompany it with the information you received as to the offer melunko@249: to distribute corresponding source code. (This alternative is melunko@249: allowed only for noncommercial distribution and only if you melunko@249: received the program in object code or executable form with such melunko@249: an offer, in accord with Subsection b above.) melunko@249: melunko@249: The source code for a work means the preferred form of the work for melunko@249: making modifications to it. For an executable work, complete source melunko@249: code means all the source code for all modules it contains, plus any melunko@249: associated interface definition files, plus the scripts used to melunko@249: control compilation and installation of the executable. However, as a melunko@249: special exception, the source code distributed need not include melunko@249: anything that is normally distributed (in either source or binary melunko@249: form) with the major components (compiler, kernel, and so on) of the melunko@249: operating system on which the executable runs, unless that component melunko@249: itself accompanies the executable. melunko@249: melunko@249: If distribution of executable or object code is made by offering melunko@249: access to copy from a designated place, then offering equivalent melunko@249: access to copy the source code from the same place counts as melunko@249: distribution of the source code, even though third parties are not melunko@249: compelled to copy the source along with the object code. melunko@249: melunko@249: 4. You may not copy, modify, sublicense, or distribute the Program melunko@249: except as expressly provided under this License. Any attempt melunko@249: otherwise to copy, modify, sublicense or distribute the Program is melunko@249: void, and will automatically terminate your rights under this License. melunko@249: However, parties who have received copies, or rights, from you under melunko@249: this License will not have their licenses terminated so long as such melunko@249: parties remain in full compliance. melunko@249: melunko@249: 5. You are not required to accept this License, since you have not melunko@249: signed it. However, nothing else grants you permission to modify or melunko@249: distribute the Program or its derivative works. These actions are melunko@249: prohibited by law if you do not accept this License. Therefore, by melunko@249: modifying or distributing the Program (or any work based on the melunko@249: Program), you indicate your acceptance of this License to do so, and melunko@249: all its terms and conditions for copying, distributing or modifying melunko@249: the Program or works based on it. melunko@249: melunko@249: 6. Each time you redistribute the Program (or any work based on the melunko@249: Program), the recipient automatically receives a license from the melunko@249: original licensor to copy, distribute or modify the Program subject to melunko@249: these terms and conditions. You may not impose any further melunko@249: restrictions on the recipients' exercise of the rights granted herein. melunko@249: You are not responsible for enforcing compliance by third parties to melunko@249: this License. melunko@249: melunko@249: 7. If, as a consequence of a court judgment or allegation of patent melunko@249: infringement or for any other reason (not limited to patent issues), melunko@249: conditions are imposed on you (whether by court order, agreement or melunko@249: otherwise) that contradict the conditions of this License, they do not melunko@249: excuse you from the conditions of this License. If you cannot melunko@249: distribute so as to satisfy simultaneously your obligations under this melunko@249: License and any other pertinent obligations, then as a consequence you melunko@249: may not distribute the Program at all. For example, if a patent melunko@249: license would not permit royalty-free redistribution of the Program by melunko@249: all those who receive copies directly or indirectly through you, then melunko@249: the only way you could satisfy both it and this License would be to melunko@249: refrain entirely from distribution of the Program. melunko@249: melunko@249: If any portion of this section is held invalid or unenforceable under melunko@249: any particular circumstance, the balance of the section is intended to melunko@249: apply and the section as a whole is intended to apply in other melunko@249: circumstances. melunko@249: melunko@249: It is not the purpose of this section to induce you to infringe any melunko@249: patents or other property right claims or to contest validity of any melunko@249: such claims; this section has the sole purpose of protecting the melunko@249: integrity of the free software distribution system, which is melunko@249: implemented by public license practices. Many people have made melunko@249: generous contributions to the wide range of software distributed melunko@249: through that system in reliance on consistent application of that melunko@249: system; it is up to the author/donor to decide if he or she is willing melunko@249: to distribute software through any other system and a licensee cannot melunko@249: impose that choice. melunko@249: melunko@249: This section is intended to make thoroughly clear what is believed to melunko@249: be a consequence of the rest of this License. melunko@249: melunko@249: 8. If the distribution and/or use of the Program is restricted in melunko@249: certain countries either by patents or by copyrighted interfaces, the melunko@249: original copyright holder who places the Program under this License melunko@249: may add an explicit geographical distribution limitation excluding melunko@249: those countries, so that distribution is permitted only in or among melunko@249: countries not thus excluded. In such case, this License incorporates melunko@249: the limitation as if written in the body of this License. melunko@249: melunko@249: 9. The Free Software Foundation may publish revised and/or new versions melunko@249: of the General Public License from time to time. Such new versions will melunko@249: be similar in spirit to the present version, but may differ in detail to melunko@249: address new problems or concerns. melunko@249: melunko@249: Each version is given a distinguishing version number. If the Program melunko@249: specifies a version number of this License which applies to it and "any melunko@249: later version", you have the option of following the terms and conditions melunko@249: either of that version or of any later version published by the Free melunko@249: Software Foundation. If the Program does not specify a version number of melunko@249: this License, you may choose any version ever published by the Free Software melunko@249: Foundation. melunko@249: melunko@249: 10. If you wish to incorporate parts of the Program into other free melunko@249: programs whose distribution conditions are different, write to the author melunko@249: to ask for permission. For software which is copyrighted by the Free melunko@249: Software Foundation, write to the Free Software Foundation; we sometimes melunko@249: make exceptions for this. Our decision will be guided by the two goals melunko@249: of preserving the free status of all derivatives of our free software and melunko@249: of promoting the sharing and reuse of software generally. melunko@249: melunko@249: NO WARRANTY melunko@249: melunko@249: 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY melunko@249: FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN melunko@249: OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES melunko@249: PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED melunko@249: OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF melunko@249: MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS melunko@249: TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE melunko@249: PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, melunko@249: REPAIR OR CORRECTION. melunko@249: melunko@249: 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING melunko@249: WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR melunko@249: REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, melunko@249: INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING melunko@249: OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED melunko@249: TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY melunko@249: YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER melunko@249: PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE melunko@249: POSSIBILITY OF SUCH DAMAGES. melunko@249: melunko@249: END OF TERMS AND CONDITIONS melunko@249: melunko@249: How to Apply These Terms to Your New Programs melunko@249: melunko@249: If you develop a new program, and you want it to be of the greatest melunko@249: possible use to the public, the best way to achieve this is to make it melunko@249: free software which everyone can redistribute and change under these terms. melunko@249: melunko@249: To do so, attach the following notices to the program. It is safest melunko@249: to attach them to the start of each source file to most effectively melunko@249: convey the exclusion of warranty; and each file should have at least melunko@249: the "copyright" line and a pointer to where the full notice is found. melunko@249: melunko@249: melunko@249: Copyright (C) melunko@249: melunko@249: This program is free software; you can redistribute it and/or modify melunko@249: it under the terms of the GNU General Public License as published by melunko@249: the Free Software Foundation; either version 2 of the License, or melunko@249: (at your option) any later version. melunko@249: melunko@249: This program is distributed in the hope that it will be useful, melunko@249: but WITHOUT ANY WARRANTY; without even the implied warranty of melunko@249: MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the melunko@249: GNU General Public License for more details. melunko@249: melunko@249: You should have received a copy of the GNU General Public License melunko@249: along with this program; if not, write to the Free Software melunko@249: Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA melunko@249: melunko@249: melunko@249: Also add information on how to contact you by electronic and paper mail. melunko@249: melunko@249: If the program is interactive, make it output a short notice like this melunko@249: when it starts in an interactive mode: melunko@249: melunko@249: Gnomovision version 69, Copyright (C) year name of author melunko@249: Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. melunko@249: This is free software, and you are welcome to redistribute it melunko@249: under certain conditions; type `show c' for details. melunko@249: melunko@249: The hypothetical commands `show w' and `show c' should show the appropriate melunko@249: parts of the General Public License. Of course, the commands you use may melunko@249: be called something other than `show w' and `show c'; they could even be melunko@249: mouse-clicks or menu items--whatever suits your program. melunko@249: melunko@249: You should also get your employer (if you work as a programmer) or your melunko@249: school, if any, to sign a "copyright disclaimer" for the program, if melunko@249: necessary. Here is a sample; alter the names: melunko@249: melunko@249: Yoyodyne, Inc., hereby disclaims all copyright interest in the program melunko@249: `Gnomovision' (which makes passes at compilers) written by James Hacker. melunko@249: melunko@249: , 1 April 1989 melunko@249: Ty Coon, President of Vice melunko@249: melunko@249: This General Public License does not permit incorporating your program into melunko@249: proprietary programs. If your program is a subroutine library, you may melunko@249: consider it more useful to permit linking proprietary applications with the melunko@249: library. If this is what you want to do, use the GNU Library General melunko@249: Public License instead of this License.
