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 Library 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. + + +\gplsec{Terms and conditions for copying, distribution and modification} + +\begin{enumerate} + +\makeatletter \setcounter{\@listctr}{-1} \makeatother + +\item [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. + +\item [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. + +\item [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: + + \begin{enumerate} + + \item [(a)] You must cause the modified files to carry prominent + notices stating that you changed the files and the date of any + change. + + \item [(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. + + \item [(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.) + + \end{enumerate} + + 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 [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: + + \begin{enumerate} + + \item [(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, + + \item [(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, + + \item [(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.) + + \end{enumerate} + + 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 [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. + +\item [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. + +\item [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. + +\item [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. + +\item [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. + +\item [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. + +\item [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. + +\begin{center} +NO WARRANTY +\end{center} + +\bfseries + +\item [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. + +\item [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{enumerate} + +\begin{center} +\textbf{END OF TERMS AND CONDITIONS} +\end{center} + + +\gplsec{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. + +\begin{verbatim} + +Copyright (C) 19yy + +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., 59 Temple Place - Suite 330, Boston, MA 02111-1307, USA. +\end{verbatim} + +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: + +\begin{verbatim} +Gnomovision version 69, Copyright (C) 19yy 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. +\end{verbatim} + +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: + +\begin{verbatim} +Yoyodyne, Inc., hereby disclaims all copyright interest in the program +`Gnomovision' (which makes passes at compilers) written by James Hacker. + +, 1 April 1989 +Ty Coon, President of Vice +\end{verbatim} + +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 Library General Public +License instead of this License. + +\gplend
