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
