[" 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 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."]
[]
["                    GNU GENERAL PUBLIC LICENSE"]
["   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."]

["OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES"]
["PROVIDE THE PROGRAM \"AS IS\" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED"]

["TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE"]
["PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,"]

[]
["  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"]
