fp@479: GNU GENERAL PUBLIC LICENSE fp@479: Version 2, June 1991 fp@479: fp@479: Copyright (C) 1989, 1991 Free Software Foundation, Inc. fp@479: 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA fp@479: Everyone is permitted to copy and distribute verbatim copies fp@479: of this license document, but changing it is not allowed. fp@479: fp@479: Preamble fp@479: fp@479: The licenses for most software are designed to take away your fp@479: freedom to share and change it. By contrast, the GNU General Public fp@479: License is intended to guarantee your freedom to share and change free fp@479: software--to make sure the software is free for all its users. This fp@479: General Public License applies to most of the Free Software fp@479: Foundation's software and to any other program whose authors commit to fp@479: using it. (Some other Free Software Foundation software is covered by fp@479: the GNU Library General Public License instead.) You can apply it to fp@479: your programs, too. fp@479: fp@479: When we speak of free software, we are referring to freedom, not fp@479: price. Our General Public Licenses are designed to make sure that you fp@479: have the freedom to distribute copies of free software (and charge for fp@479: this service if you wish), that you receive source code or can get it fp@479: if you want it, that you can change the software or use pieces of it fp@479: in new free programs; and that you know you can do these things. fp@479: fp@479: To protect your rights, we need to make restrictions that forbid fp@479: anyone to deny you these rights or to ask you to surrender the rights. fp@479: These restrictions translate to certain responsibilities for you if you fp@479: distribute copies of the software, or if you modify it. fp@479: fp@479: For example, if you distribute copies of such a program, whether fp@479: gratis or for a fee, you must give the recipients all the rights that fp@479: you have. You must make sure that they, too, receive or can get the fp@479: source code. And you must show them these terms so they know their fp@479: rights. fp@479: fp@479: We protect your rights with two steps: (1) copyright the software, and fp@479: (2) offer you this license which gives you legal permission to copy, fp@479: distribute and/or modify the software. fp@479: fp@479: Also, for each author's protection and ours, we want to make certain fp@479: that everyone understands that there is no warranty for this free fp@479: software. If the software is modified by someone else and passed on, we fp@479: want its recipients to know that what they have is not the original, so fp@479: that any problems introduced by others will not reflect on the original fp@479: authors' reputations. fp@479: fp@479: Finally, any free program is threatened constantly by software fp@479: patents. We wish to avoid the danger that redistributors of a free fp@479: program will individually obtain patent licenses, in effect making the fp@479: program proprietary. To prevent this, we have made it clear that any fp@479: patent must be licensed for everyone's free use or not licensed at all. fp@479: fp@479: The precise terms and conditions for copying, distribution and fp@479: modification follow. fp@479: fp@479: GNU GENERAL PUBLIC LICENSE fp@479: TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION fp@479: fp@479: 0. This License applies to any program or other work which contains fp@479: a notice placed by the copyright holder saying it may be distributed fp@479: under the terms of this General Public License. The "Program", below, fp@479: refers to any such program or work, and a "work based on the Program" fp@479: means either the Program or any derivative work under copyright law: fp@479: that is to say, a work containing the Program or a portion of it, fp@479: either verbatim or with modifications and/or translated into another fp@479: language. (Hereinafter, translation is included without limitation in fp@479: the term "modification".) Each licensee is addressed as "you". fp@479: fp@479: Activities other than copying, distribution and modification are not fp@479: covered by this License; they are outside its scope. The act of fp@479: running the Program is not restricted, and the output from the Program fp@479: is covered only if its contents constitute a work based on the fp@479: Program (independent of having been made by running the Program). fp@479: Whether that is true depends on what the Program does. fp@479: fp@479: 1. You may copy and distribute verbatim copies of the Program's fp@479: source code as you receive it, in any medium, provided that you fp@479: conspicuously and appropriately publish on each copy an appropriate fp@479: copyright notice and disclaimer of warranty; keep intact all the fp@479: notices that refer to this License and to the absence of any warranty; fp@479: and give any other recipients of the Program a copy of this License fp@479: along with the Program. fp@479: fp@479: You may charge a fee for the physical act of transferring a copy, and fp@479: you may at your option offer warranty protection in exchange for a fee. fp@479: fp@479: 2. You may modify your copy or copies of the Program or any portion fp@479: of it, thus forming a work based on the Program, and copy and fp@479: distribute such modifications or work under the terms of Section 1 fp@479: above, provided that you also meet all of these conditions: fp@479: fp@479: a) You must cause the modified files to carry prominent notices fp@479: stating that you changed the files and the date of any change. fp@479: fp@479: b) You must cause any work that you distribute or publish, that in fp@479: whole or in part contains or is derived from the Program or any fp@479: part thereof, to be licensed as a whole at no charge to all third fp@479: parties under the terms of this License. fp@479: fp@479: c) If the modified program normally reads commands interactively fp@479: when run, you must cause it, when started running for such fp@479: interactive use in the most ordinary way, to print or display an fp@479: announcement including an appropriate copyright notice and a fp@479: notice that there is no warranty (or else, saying that you provide fp@479: a warranty) and that users may redistribute the program under fp@479: these conditions, and telling the user how to view a copy of this fp@479: License. (Exception: if the Program itself is interactive but fp@479: does not normally print such an announcement, your work based on fp@479: the Program is not required to print an announcement.) fp@479: fp@479: These requirements apply to the modified work as a whole. If fp@479: identifiable sections of that work are not derived from the Program, fp@479: and can be reasonably considered independent and separate works in fp@479: themselves, then this License, and its terms, do not apply to those fp@479: sections when you distribute them as separate works. But when you fp@479: distribute the same sections as part of a whole which is a work based fp@479: on the Program, the distribution of the whole must be on the terms of fp@479: this License, whose permissions for other licensees extend to the fp@479: entire whole, and thus to each and every part regardless of who wrote it. fp@479: fp@479: Thus, it is not the intent of this section to claim rights or contest fp@479: your rights to work written entirely by you; rather, the intent is to fp@479: exercise the right to control the distribution of derivative or fp@479: collective works based on the Program. fp@479: fp@479: In addition, mere aggregation of another work not based on the Program fp@479: with the Program (or with a work based on the Program) on a volume of fp@479: a storage or distribution medium does not bring the other work under fp@479: the scope of this License. fp@479: fp@479: 3. You may copy and distribute the Program (or a work based on it, fp@479: under Section 2) in object code or executable form under the terms of fp@479: Sections 1 and 2 above provided that you also do one of the following: fp@479: fp@479: a) Accompany it with the complete corresponding machine-readable fp@479: source code, which must be distributed under the terms of Sections fp@479: 1 and 2 above on a medium customarily used for software interchange; or, fp@479: fp@479: b) Accompany it with a written offer, valid for at least three fp@479: years, to give any third party, for a charge no more than your fp@479: cost of physically performing source distribution, a complete fp@479: machine-readable copy of the corresponding source code, to be fp@479: distributed under the terms of Sections 1 and 2 above on a medium fp@479: customarily used for software interchange; or, fp@479: fp@479: c) Accompany it with the information you received as to the offer fp@479: to distribute corresponding source code. (This alternative is fp@479: allowed only for noncommercial distribution and only if you fp@479: received the program in object code or executable form with such fp@479: an offer, in accord with Subsection b above.) fp@479: fp@479: The source code for a work means the preferred form of the work for fp@479: making modifications to it. For an executable work, complete source fp@479: code means all the source code for all modules it contains, plus any fp@479: associated interface definition files, plus the scripts used to fp@479: control compilation and installation of the executable. However, as a fp@479: special exception, the source code distributed need not include fp@479: anything that is normally distributed (in either source or binary fp@479: form) with the major components (compiler, kernel, and so on) of the fp@479: operating system on which the executable runs, unless that component fp@479: itself accompanies the executable. fp@479: fp@479: If distribution of executable or object code is made by offering fp@479: access to copy from a designated place, then offering equivalent fp@479: access to copy the source code from the same place counts as fp@479: distribution of the source code, even though third parties are not fp@479: compelled to copy the source along with the object code. fp@479: fp@479: 4. You may not copy, modify, sublicense, or distribute the Program fp@479: except as expressly provided under this License. Any attempt fp@479: otherwise to copy, modify, sublicense or distribute the Program is fp@479: void, and will automatically terminate your rights under this License. fp@479: However, parties who have received copies, or rights, from you under fp@479: this License will not have their licenses terminated so long as such fp@479: parties remain in full compliance. fp@479: fp@479: 5. You are not required to accept this License, since you have not fp@479: signed it. However, nothing else grants you permission to modify or fp@479: distribute the Program or its derivative works. These actions are fp@479: prohibited by law if you do not accept this License. Therefore, by fp@479: modifying or distributing the Program (or any work based on the fp@479: Program), you indicate your acceptance of this License to do so, and fp@479: all its terms and conditions for copying, distributing or modifying fp@479: the Program or works based on it. fp@479: fp@479: 6. Each time you redistribute the Program (or any work based on the fp@479: Program), the recipient automatically receives a license from the fp@479: original licensor to copy, distribute or modify the Program subject to fp@479: these terms and conditions. You may not impose any further fp@479: restrictions on the recipients' exercise of the rights granted herein. fp@479: You are not responsible for enforcing compliance by third parties to fp@479: this License. fp@479: fp@479: 7. If, as a consequence of a court judgment or allegation of patent fp@479: infringement or for any other reason (not limited to patent issues), fp@479: conditions are imposed on you (whether by court order, agreement or fp@479: otherwise) that contradict the conditions of this License, they do not fp@479: excuse you from the conditions of this License. If you cannot fp@479: distribute so as to satisfy simultaneously your obligations under this fp@479: License and any other pertinent obligations, then as a consequence you fp@479: may not distribute the Program at all. For example, if a patent fp@479: license would not permit royalty-free redistribution of the Program by fp@479: all those who receive copies directly or indirectly through you, then fp@479: the only way you could satisfy both it and this License would be to fp@479: refrain entirely from distribution of the Program. fp@479: fp@479: If any portion of this section is held invalid or unenforceable under fp@479: any particular circumstance, the balance of the section is intended to fp@479: apply and the section as a whole is intended to apply in other fp@479: circumstances. fp@479: fp@479: It is not the purpose of this section to induce you to infringe any fp@479: patents or other property right claims or to contest validity of any fp@479: such claims; this section has the sole purpose of protecting the fp@479: integrity of the free software distribution system, which is fp@479: implemented by public license practices. Many people have made fp@479: generous contributions to the wide range of software distributed fp@479: through that system in reliance on consistent application of that fp@479: system; it is up to the author/donor to decide if he or she is willing fp@479: to distribute software through any other system and a licensee cannot fp@479: impose that choice. fp@479: fp@479: This section is intended to make thoroughly clear what is believed to fp@479: be a consequence of the rest of this License. fp@479: fp@479: 8. If the distribution and/or use of the Program is restricted in fp@479: certain countries either by patents or by copyrighted interfaces, the fp@479: original copyright holder who places the Program under this License fp@479: may add an explicit geographical distribution limitation excluding fp@479: those countries, so that distribution is permitted only in or among fp@479: countries not thus excluded. In such case, this License incorporates fp@479: the limitation as if written in the body of this License. fp@479: fp@479: 9. The Free Software Foundation may publish revised and/or new versions fp@479: of the General Public License from time to time. Such new versions will fp@479: be similar in spirit to the present version, but may differ in detail to fp@479: address new problems or concerns. fp@479: fp@479: Each version is given a distinguishing version number. If the Program fp@479: specifies a version number of this License which applies to it and "any fp@479: later version", you have the option of following the terms and conditions fp@479: either of that version or of any later version published by the Free fp@479: Software Foundation. If the Program does not specify a version number of fp@479: this License, you may choose any version ever published by the Free Software fp@479: Foundation. fp@479: fp@479: 10. If you wish to incorporate parts of the Program into other free fp@479: programs whose distribution conditions are different, write to the author fp@479: to ask for permission. For software which is copyrighted by the Free fp@479: Software Foundation, write to the Free Software Foundation; we sometimes fp@479: make exceptions for this. Our decision will be guided by the two goals fp@479: of preserving the free status of all derivatives of our free software and fp@479: of promoting the sharing and reuse of software generally. fp@479: fp@479: NO WARRANTY fp@479: fp@479: 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY fp@479: FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN fp@479: OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES fp@479: PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED fp@479: OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF fp@479: MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS fp@479: TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE fp@479: PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, fp@479: REPAIR OR CORRECTION. fp@479: fp@479: 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING fp@479: WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR fp@479: REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, fp@479: INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING fp@479: OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED fp@479: TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY fp@479: YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER fp@479: PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE fp@479: POSSIBILITY OF SUCH DAMAGES. fp@479: fp@479: END OF TERMS AND CONDITIONS fp@479: fp@479: How to Apply These Terms to Your New Programs fp@479: fp@479: If you develop a new program, and you want it to be of the greatest fp@479: possible use to the public, the best way to achieve this is to make it fp@479: free software which everyone can redistribute and change under these terms. fp@479: fp@479: To do so, attach the following notices to the program. It is safest fp@479: to attach them to the start of each source file to most effectively fp@479: convey the exclusion of warranty; and each file should have at least fp@479: the "copyright" line and a pointer to where the full notice is found. fp@479: fp@479: fp@479: Copyright (C) fp@479: fp@479: This program is free software; you can redistribute it and/or modify fp@479: it under the terms of the GNU General Public License as published by fp@479: the Free Software Foundation; either version 2 of the License, or fp@479: (at your option) any later version. fp@479: fp@479: This program is distributed in the hope that it will be useful, fp@479: but WITHOUT ANY WARRANTY; without even the implied warranty of fp@479: MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the fp@479: GNU General Public License for more details. fp@479: fp@479: You should have received a copy of the GNU General Public License fp@479: along with this program; if not, write to the Free Software fp@479: Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA fp@479: fp@479: fp@479: Also add information on how to contact you by electronic and paper mail. fp@479: fp@479: If the program is interactive, make it output a short notice like this fp@479: when it starts in an interactive mode: fp@479: fp@479: Gnomovision version 69, Copyright (C) year name of author fp@479: Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. fp@479: This is free software, and you are welcome to redistribute it fp@479: under certain conditions; type `show c' for details. fp@479: fp@479: The hypothetical commands `show w' and `show c' should show the appropriate fp@479: parts of the General Public License. Of course, the commands you use may fp@479: be called something other than `show w' and `show c'; they could even be fp@479: mouse-clicks or menu items--whatever suits your program. fp@479: fp@479: You should also get your employer (if you work as a programmer) or your fp@479: school, if any, to sign a "copyright disclaimer" for the program, if fp@479: necessary. Here is a sample; alter the names: fp@479: fp@479: Yoyodyne, Inc., hereby disclaims all copyright interest in the program fp@479: `Gnomovision' (which makes passes at compilers) written by James Hacker. fp@479: fp@479: , 1 April 1989 fp@479: Ty Coon, President of Vice fp@479: fp@479: This General Public License does not permit incorporating your program into fp@479: proprietary programs. If your program is a subroutine library, you may fp@479: consider it more useful to permit linking proprietary applications with the fp@479: library. If this is what you want to do, use the GNU Library General fp@479: Public License instead of this License.
