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. + + one line to give the program's name and an 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.
