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. + +\item 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. + +\item 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. + +\item 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. + +\item 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. + +\item 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. + +\item 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.

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. - -\begincentered - %% so … these aren’t actual headings‽ - \Largefont{\smallcaps{% - Terms and Conditions For Copying, Distribution and Modification - }} -\endcentered - -\beginenumeration -\item 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. - -\item 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. - -\item 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: - - \beginenumeration - - \item You must cause the modified files to carry prominent notices - stating that you changed the files and the date of any change. - - \item 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. - - \item 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.) - - \endenumeration - - - 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. - -\item 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: - - \beginenumeration - - \item 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, - - \item 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, - - \item 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.) - - \endenumeration - - - 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. - -\item 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. - -\item 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. - -\item 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. - -\item 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. - -\item 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. - -\item 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. - -\item 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. - -\begincentered - \Largefont{\smallcaps{No Warranty}} -\endcentered - -\item \smallcaps{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.} - -\item \smallcaps{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.} - -\endenumeration - - -\begincentered - \Largefont{\smallcaps{End of Terms and Conditions}} -\endcentered - - -\pagebreak[2] - -%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% -\fakesection {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. - -\beginnarrower - 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.
