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