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 +``````````````````````````````````````````````````````````````` + +1. 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. + +2. 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. + +3. 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. + +4. 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. + +5. 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. + +6. 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. + +7. 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. + +8. 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. + +9. 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. + +10. 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. + +11. 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. + +12. 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. + +13. 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. + +Appendix: 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. + +:: + + + one line to give the program's name and a brief idea of what it does. + Copyright (C) yyyy name of author + + 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. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program; if not, write to the Free Software + Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA. + +.. + + + +Also add information on how to contact you by electronic and paper mail. + +If the program is interactive, make it output a short notice like this when it +starts in an interactive mode: + +:: + + + Gnomovision version 69, Copyright (C) year name of author + Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type 'show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type 'show c' for details. + +.. + + + +The hypothetical commands 'show w' and 'show c' should show the appropriate parts of +the General Public License. Of course, the commands you use may be called something +other than 'show w' and 'show c'; they could even be mouse-clicks or menu +items—whatever suits your program. + +You should also get your employer (if you work as a programmer) or your school, if +any, to sign a “copyright disclaimer” for the program, if necessary. Here is a +sample; alter the names: + +:: + + + Yoyodyne, Inc., hereby disclaims all copyright interest in the program + 'Gnomovision' (which makes passes at compilers) written by James Hacker. + + signature of Ty Coon, 1 April 1989 + Ty Coon, President of Vice + +.. + + + +This General Public License does not permit incorporating your program into +proprietary programs. If your program is a subroutine library, you may consider it +more useful to permit linking proprietary applications with the library. If this is +what you want to do, use the GNU Lesser General Public License instead of this +License. -- cgit v0.9.1
