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