fp@197: GNU GENERAL PUBLIC LICENSE fp@197: Version 2, June 1991 fp@197: fp@197: Copyright (C) 1989, 1991 Free Software Foundation, Inc. fp@197: 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA fp@197: Everyone is permitted to copy and distribute verbatim copies fp@197: of this license document, but changing it is not allowed. fp@197: fp@197: Preamble fp@197: fp@197: The licenses for most software are designed to take away your fp@197: freedom to share and change it. By contrast, the GNU General Public fp@197: License is intended to guarantee your freedom to share and change free fp@197: software--to make sure the software is free for all its users. This fp@197: General Public License applies to most of the Free Software fp@197: Foundation's software and to any other program whose authors commit to fp@197: using it. (Some other Free Software Foundation software is covered by fp@197: the GNU Lesser General Public License instead.) You can apply it to fp@197: your programs, too. fp@197: fp@197: When we speak of free software, we are referring to freedom, not fp@197: price. Our General Public Licenses are designed to make sure that you fp@197: have the freedom to distribute copies of free software (and charge for fp@197: this service if you wish), that you receive source code or can get it fp@197: if you want it, that you can change the software or use pieces of it fp@197: in new free programs; and that you know you can do these things. fp@197: fp@197: To protect your rights, we need to make restrictions that forbid fp@197: anyone to deny you these rights or to ask you to surrender the rights. fp@197: These restrictions translate to certain responsibilities for you if you fp@197: distribute copies of the software, or if you modify it. fp@197: fp@197: For example, if you distribute copies of such a program, whether fp@197: gratis or for a fee, you must give the recipients all the rights that fp@197: you have. You must make sure that they, too, receive or can get the fp@197: source code. And you must show them these terms so they know their fp@197: rights. fp@197: fp@197: We protect your rights with two steps: (1) copyright the software, and fp@197: (2) offer you this license which gives you legal permission to copy, fp@197: distribute and/or modify the software. fp@197: fp@197: Also, for each author's protection and ours, we want to make certain fp@197: that everyone understands that there is no warranty for this free fp@197: software. If the software is modified by someone else and passed on, we fp@197: want its recipients to know that what they have is not the original, so fp@197: that any problems introduced by others will not reflect on the original fp@197: authors' reputations. fp@197: fp@197: Finally, any free program is threatened constantly by software fp@197: patents. We wish to avoid the danger that redistributors of a free fp@197: program will individually obtain patent licenses, in effect making the fp@197: program proprietary. To prevent this, we have made it clear that any fp@197: patent must be licensed for everyone's free use or not licensed at all. fp@197: fp@197: The precise terms and conditions for copying, distribution and fp@197: modification follow. fp@197: fp@197: GNU GENERAL PUBLIC LICENSE fp@197: TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION fp@197: fp@197: 0. This License applies to any program or other work which contains fp@197: a notice placed by the copyright holder saying it may be distributed fp@197: under the terms of this General Public License. The "Program", below, fp@197: refers to any such program or work, and a "work based on the Program" fp@197: means either the Program or any derivative work under copyright law: fp@197: that is to say, a work containing the Program or a portion of it, fp@197: either verbatim or with modifications and/or translated into another fp@197: language. (Hereinafter, translation is included without limitation in fp@197: the term "modification".) Each licensee is addressed as "you". fp@197: fp@197: Activities other than copying, distribution and modification are not fp@197: covered by this License; they are outside its scope. The act of fp@197: running the Program is not restricted, and the output from the Program fp@197: is covered only if its contents constitute a work based on the fp@197: Program (independent of having been made by running the Program). fp@197: Whether that is true depends on what the Program does. fp@197: fp@197: 1. You may copy and distribute verbatim copies of the Program's fp@197: source code as you receive it, in any medium, provided that you fp@197: conspicuously and appropriately publish on each copy an appropriate fp@197: copyright notice and disclaimer of warranty; keep intact all the fp@197: notices that refer to this License and to the absence of any warranty; fp@197: and give any other recipients of the Program a copy of this License fp@197: along with the Program. fp@197: fp@197: You may charge a fee for the physical act of transferring a copy, and fp@197: you may at your option offer warranty protection in exchange for a fee. fp@197: fp@197: 2. You may modify your copy or copies of the Program or any portion fp@197: of it, thus forming a work based on the Program, and copy and fp@197: distribute such modifications or work under the terms of Section 1 fp@197: above, provided that you also meet all of these conditions: fp@197: fp@197: a) You must cause the modified files to carry prominent notices fp@197: stating that you changed the files and the date of any change. fp@197: fp@197: b) You must cause any work that you distribute or publish, that in fp@197: whole or in part contains or is derived from the Program or any fp@197: part thereof, to be licensed as a whole at no charge to all third fp@197: parties under the terms of this License. fp@197: fp@197: c) If the modified program normally reads commands interactively fp@197: when run, you must cause it, when started running for such fp@197: interactive use in the most ordinary way, to print or display an fp@197: announcement including an appropriate copyright notice and a fp@197: notice that there is no warranty (or else, saying that you provide fp@197: a warranty) and that users may redistribute the program under fp@197: these conditions, and telling the user how to view a copy of this fp@197: License. (Exception: if the Program itself is interactive but fp@197: does not normally print such an announcement, your work based on fp@197: the Program is not required to print an announcement.) fp@197: fp@197: These requirements apply to the modified work as a whole. If fp@197: identifiable sections of that work are not derived from the Program, fp@197: and can be reasonably considered independent and separate works in fp@197: themselves, then this License, and its terms, do not apply to those fp@197: sections when you distribute them as separate works. But when you fp@197: distribute the same sections as part of a whole which is a work based fp@197: on the Program, the distribution of the whole must be on the terms of fp@197: this License, whose permissions for other licensees extend to the fp@197: entire whole, and thus to each and every part regardless of who wrote it. fp@197: fp@197: Thus, it is not the intent of this section to claim rights or contest fp@197: your rights to work written entirely by you; rather, the intent is to fp@197: exercise the right to control the distribution of derivative or fp@197: collective works based on the Program. fp@197: fp@197: In addition, mere aggregation of another work not based on the Program fp@197: with the Program (or with a work based on the Program) on a volume of fp@197: a storage or distribution medium does not bring the other work under fp@197: the scope of this License. fp@197: fp@197: 3. You may copy and distribute the Program (or a work based on it, fp@197: under Section 2) in object code or executable form under the terms of fp@197: Sections 1 and 2 above provided that you also do one of the following: fp@197: fp@197: a) Accompany it with the complete corresponding machine-readable fp@197: source code, which must be distributed under the terms of Sections fp@197: 1 and 2 above on a medium customarily used for software interchange; or, fp@197: fp@197: b) Accompany it with a written offer, valid for at least three fp@197: years, to give any third party, for a charge no more than your fp@197: cost of physically performing source distribution, a complete fp@197: machine-readable copy of the corresponding source code, to be fp@197: distributed under the terms of Sections 1 and 2 above on a medium fp@197: customarily used for software interchange; or, fp@197: fp@197: c) Accompany it with the information you received as to the offer fp@197: to distribute corresponding source code. (This alternative is fp@197: allowed only for noncommercial distribution and only if you fp@197: received the program in object code or executable form with such fp@197: an offer, in accord with Subsection b above.) fp@197: fp@197: The source code for a work means the preferred form of the work for fp@197: making modifications to it. For an executable work, complete source fp@197: code means all the source code for all modules it contains, plus any fp@197: associated interface definition files, plus the scripts used to fp@197: control compilation and installation of the executable. However, as a fp@197: special exception, the source code distributed need not include fp@197: anything that is normally distributed (in either source or binary fp@197: form) with the major components (compiler, kernel, and so on) of the fp@197: operating system on which the executable runs, unless that component fp@197: itself accompanies the executable. fp@197: fp@197: If distribution of executable or object code is made by offering fp@197: access to copy from a designated place, then offering equivalent fp@197: access to copy the source code from the same place counts as fp@197: distribution of the source code, even though third parties are not fp@197: compelled to copy the source along with the object code. fp@197: fp@197: 4. You may not copy, modify, sublicense, or distribute the Program fp@197: except as expressly provided under this License. Any attempt fp@197: otherwise to copy, modify, sublicense or distribute the Program is fp@197: void, and will automatically terminate your rights under this License. fp@197: However, parties who have received copies, or rights, from you under fp@197: this License will not have their licenses terminated so long as such fp@197: parties remain in full compliance. fp@197: fp@197: 5. You are not required to accept this License, since you have not fp@197: signed it. However, nothing else grants you permission to modify or fp@197: distribute the Program or its derivative works. These actions are fp@197: prohibited by law if you do not accept this License. Therefore, by fp@197: modifying or distributing the Program (or any work based on the fp@197: Program), you indicate your acceptance of this License to do so, and fp@197: all its terms and conditions for copying, distributing or modifying fp@197: the Program or works based on it. fp@197: fp@197: 6. Each time you redistribute the Program (or any work based on the fp@197: Program), the recipient automatically receives a license from the fp@197: original licensor to copy, distribute or modify the Program subject to fp@197: these terms and conditions. You may not impose any further fp@197: restrictions on the recipients' exercise of the rights granted herein. fp@197: You are not responsible for enforcing compliance by third parties to fp@197: this License. fp@197: fp@197: 7. If, as a consequence of a court judgment or allegation of patent fp@197: infringement or for any other reason (not limited to patent issues), fp@197: conditions are imposed on you (whether by court order, agreement or fp@197: otherwise) that contradict the conditions of this License, they do not fp@197: excuse you from the conditions of this License. If you cannot fp@197: distribute so as to satisfy simultaneously your obligations under this fp@197: License and any other pertinent obligations, then as a consequence you fp@197: may not distribute the Program at all. For example, if a patent fp@197: license would not permit royalty-free redistribution of the Program by fp@197: all those who receive copies directly or indirectly through you, then fp@197: the only way you could satisfy both it and this License would be to fp@197: refrain entirely from distribution of the Program. fp@197: fp@197: If any portion of this section is held invalid or unenforceable under fp@197: any particular circumstance, the balance of the section is intended to fp@197: apply and the section as a whole is intended to apply in other fp@197: circumstances. fp@197: fp@197: It is not the purpose of this section to induce you to infringe any fp@197: patents or other property right claims or to contest validity of any fp@197: such claims; this section has the sole purpose of protecting the fp@197: integrity of the free software distribution system, which is fp@197: implemented by public license practices. Many people have made fp@197: generous contributions to the wide range of software distributed fp@197: through that system in reliance on consistent application of that fp@197: system; it is up to the author/donor to decide if he or she is willing fp@197: to distribute software through any other system and a licensee cannot fp@197: impose that choice. fp@197: fp@197: This section is intended to make thoroughly clear what is believed to fp@197: be a consequence of the rest of this License. fp@197: fp@197: 8. If the distribution and/or use of the Program is restricted in fp@197: certain countries either by patents or by copyrighted interfaces, the fp@197: original copyright holder who places the Program under this License fp@197: may add an explicit geographical distribution limitation excluding fp@197: those countries, so that distribution is permitted only in or among fp@197: countries not thus excluded. In such case, this License incorporates fp@197: the limitation as if written in the body of this License. fp@197: fp@197: 9. The Free Software Foundation may publish revised and/or new versions fp@197: of the General Public License from time to time. Such new versions will fp@197: be similar in spirit to the present version, but may differ in detail to fp@197: address new problems or concerns. fp@197: fp@197: Each version is given a distinguishing version number. If the Program fp@197: specifies a version number of this License which applies to it and "any fp@197: later version", you have the option of following the terms and conditions fp@197: either of that version or of any later version published by the Free fp@197: Software Foundation. If the Program does not specify a version number of fp@197: this License, you may choose any version ever published by the Free Software fp@197: Foundation. fp@197: fp@197: 10. If you wish to incorporate parts of the Program into other free fp@197: programs whose distribution conditions are different, write to the author fp@197: to ask for permission. For software which is copyrighted by the Free fp@197: Software Foundation, write to the Free Software Foundation; we sometimes fp@197: make exceptions for this. Our decision will be guided by the two goals fp@197: of preserving the free status of all derivatives of our free software and fp@197: of promoting the sharing and reuse of software generally. fp@197: fp@197: NO WARRANTY fp@197: fp@197: 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY fp@197: FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN fp@197: OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES fp@197: PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED fp@197: OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF fp@197: MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS fp@197: TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE fp@197: PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, fp@197: REPAIR OR CORRECTION. fp@197: fp@197: 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING fp@197: WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR fp@197: REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, fp@197: INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING fp@197: OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED fp@197: TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY fp@197: YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER fp@197: PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE fp@197: POSSIBILITY OF SUCH DAMAGES. fp@197: fp@197: END OF TERMS AND CONDITIONS fp@197: fp@197: How to Apply These Terms to Your New Programs fp@197: fp@197: If you develop a new program, and you want it to be of the greatest fp@197: possible use to the public, the best way to achieve this is to make it fp@197: free software which everyone can redistribute and change under these terms. fp@197: fp@197: To do so, attach the following notices to the program. It is safest fp@197: to attach them to the start of each source file to most effectively fp@197: convey the exclusion of warranty; and each file should have at least fp@197: the "copyright" line and a pointer to where the full notice is found. fp@197: fp@197: <one line to give the program's name and a brief idea of what it does.> fp@197: Copyright (C) <year> <name of author> fp@197: fp@197: This program is free software; you can redistribute it and/or modify fp@197: it under the terms of the GNU General Public License as published by fp@197: the Free Software Foundation; either version 2 of the License, or fp@197: (at your option) any later version. fp@197: fp@197: This program is distributed in the hope that it will be useful, fp@197: but WITHOUT ANY WARRANTY; without even the implied warranty of fp@197: MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the fp@197: GNU General Public License for more details. fp@197: fp@197: You should have received a copy of the GNU General Public License fp@197: along with this program; if not, write to the Free Software fp@197: Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA fp@197: fp@197: fp@197: Also add information on how to contact you by electronic and paper mail. fp@197: fp@197: If the program is interactive, make it output a short notice like this fp@197: when it starts in an interactive mode: fp@197: fp@197: Gnomovision version 69, Copyright (C) year name of author fp@197: Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. fp@197: This is free software, and you are welcome to redistribute it fp@197: under certain conditions; type `show c' for details. fp@197: fp@197: The hypothetical commands `show w' and `show c' should show the appropriate fp@197: parts of the General Public License. Of course, the commands you use may fp@197: be called something other than `show w' and `show c'; they could even be fp@197: mouse-clicks or menu items--whatever suits your program. fp@197: fp@197: You should also get your employer (if you work as a programmer) or your fp@197: school, if any, to sign a "copyright disclaimer" for the program, if fp@197: necessary. Here is a sample; alter the names: fp@197: fp@197: Yoyodyne, Inc., hereby disclaims all copyright interest in the program fp@197: `Gnomovision' (which makes passes at compilers) written by James Hacker. fp@197: fp@197: <signature of Ty Coon>, 1 April 1989 fp@197: Ty Coon, President of Vice fp@197: fp@197: This General Public License does not permit incorporating your program into fp@197: proprietary programs. If your program is a subroutine library, you may fp@197: consider it more useful to permit linking proprietary applications with the fp@197: library. If this is what you want to do, use the GNU Lesser General fp@197: Public License instead of this License.
