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 |
