| + | | ||
| + | of this license document, but changing it is not allowed. | ||
| + | |||
| + | Preamble | ||
| + | |||
| + | The licenses for most software are designed to take away your | ||
| + | freedom to share and change it. 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. | ||
| + | General Public License applies to most of the Free Software | ||
| + | Foundation' | ||
| + | using it. (Some other Free Software Foundation software is covered by | ||
| + | the GNU Lesser General Public License instead.) | ||
| + | your programs, too. | ||
| + | |||
| + | When we speak of free software, we are referring to freedom, not | ||
| + | price. | ||
| + | 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' | ||
| + | that everyone understands that there is no warranty for this free | ||
| + | software. | ||
| + | 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' | ||
| + | |||
| + | Finally, any free program is threatened constantly by software | ||
| + | patents. | ||
| + | program will individually obtain patent licenses, in effect making the | ||
| + | program proprietary. | ||
| + | patent must be licensed for everyone' | ||
| + | |||
| + | The precise terms and conditions for copying, distribution and | ||
| + | modification follow. | ||
| + | |||
| + | GNU GENERAL PUBLIC LICENSE | ||
| + | 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. | ||
| + | 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. | ||
| + | the term " | ||
| + | |||
| + | Activities other than copying, distribution and modification are not | ||
| + | covered by this License; they are outside its scope. | ||
| + | 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' | ||
| + | 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. | ||
| + | does not normally print such an announcement, | ||
| + | the Program is not required to print an announcement.) | ||
| + | |||
| + | These requirements apply to the modified work as a whole. | ||
| + | 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. | ||
| + | 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; | ||
| + | |||
| + | 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, | ||
| + | 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; | ||
| + | |||
| + | 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. | ||
| + | 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. | ||
| + | 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. | ||
| + | prohibited by law if you do not accept this License. | ||
| + | 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. | ||
| + | restrictions on the recipients' | ||
| + | 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. | ||
| + | distribute so as to satisfy simultaneously your obligations under this | ||
| + | License and any other pertinent obligations, | ||
| + | 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, | ||
| + | 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. | ||
| + | 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/ | ||
| + | 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. | ||
| + | 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. | ||
| + | specifies a version number of this License which applies to it and "any | ||
| + | later version", | ||
| + | either of that version or of any later version published by the Free | ||
| + | Software Foundation. | ||
| + | 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. | ||
| + | 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. | ||
| + | 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 | ||
