Version 2, June 1991, available at +<http: + +GNU General Public License + +Version 2, June 1991 + +Copyright (C) 1989, 1991 Free Software Foundation, Inc. +59 Temple Place - Suite 330, Boston, MA 02111-1307, USA + +Everyone is permitted to copy and distribute verbatim copies 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. 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. + +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.

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.
