By contrast, the GNU General Public\nLicense is intended to guarantee your freedom to share and change free\nsoftware---to make sure the software is free for all its users.  This\nGeneral Public License applies to most of the Free Software\nFoundation's software and to any other program whose authors commit to\nusing it.  (Some other Free Software Foundation software is covered by\nthe GNU Library General Public License instead.)  You can apply it to\nyour programs, too.\n\nWhen we speak of free software, we are referring to freedom, not\nprice.  Our General Public Licenses are designed to make sure that you\nhave the freedom to distribute copies of free software (and charge for\nthis service if you wish), that you receive source code or can get it\nif you want it, that you can change the software or use pieces of it\nin new free programs; and that you know you can do these things.\n\nTo protect your rights, we need to make restrictions that forbid\nanyone to deny you these rights or to ask you to surrender the rights.\nThese restrictions translate to certain responsibilities for you if you\ndistribute copies of the software, or if you modify it.\n\nFor example, if you distribute copies of such a program, whether\ngratis or for a fee, you must give the recipients all the rights that\nyou have.  You must make sure that they, too, receive or can get the\nsource code.  And you must show them these terms so they know their\nrights.\n\nWe protect your rights with two steps: (1) copyright the software, and\n(2) offer you this license which gives you legal permission to copy,\ndistribute and/or modify the software.\n\nAlso, for each author's protection and ours, we want to make certain\nthat everyone understands that there is no warranty for this free\nsoftware.  If the software is modified by someone else and passed on, we\nwant its recipients to know that what they have is not the original, so\nthat any problems introduced by others will not reflect on the original\nauthors' reputations.\n\nFinally, any free program is threatened constantly by software\npatents.  We wish to avoid the danger that redistributors of a free\nprogram will individually obtain patent licenses, in effect making the\nprogram proprietary.  To prevent this, we have made it clear that any\npatent must be licensed for everyone's free use or not licensed at all.\n\nThe precise terms and conditions for copying, distribution and\nmodification follow.\n"

                    "name": "TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION",
                    "content": "0.  This  License  applies to any program or other work which contains a notice placed by the\ncopyright holder saying it may be distributed under the terms of this General Public  Li‐\ncense.  The ``Program'', below, refers to any such program or work, and a ``work based on\nthe  Program''  means either the Program or any derivative work under copyright law: that\nis to say, a work containing the Program or a portion of it, either verbatim or with mod‐\nifications and/or translated into another language.   (Hereinafter,  translation  is  in‐\ncluded  without  limitation in the term ``modification''.)  Each licensee is addressed as\n``you''.\n\nActivities other than copying, distribution and modification are not covered by this  Li‐\ncense; they are outside its scope.  The act of running the Program is not restricted, and\nthe  output  from  the Program is covered only if its contents constitute a work based on\nthe Program (independent of having been made by running the Program).   Whether  that  is\ntrue depends on what the Program does.\n\n1.  You  may  copy and distribute verbatim copies of the Program's source code as you receive\nit, in any medium, provided that you conspicuously and appropriately publish on each copy\nan appropriate copyright notice and disclaimer of warranty; keep intact all  the  notices\nthat refer to this License and to the absence of any warranty; and give any other recipi‐\nents of the Program a copy of this License along with the Program.\n\nYou may charge a fee for the physical act of transferring a copy, and you may at your op‐\ntion offer warranty protection in exchange for a fee.\n\n2.  You  may  modify  your copy or copies of the Program or any portion of it, thus forming a\nwork based on the Program, and copy and distribute such modifications or work  under  the\nterms of Section 1 above, provided that you also meet all of these conditions:\n\na.  You must cause the modified files to carry prominent notices stating that you changed\nthe files and the date of any change.\n\nb.  You must cause any work that you distribute or publish, that in whole or in part con‐\ntains  or  is derived from the Program or any part thereof, to be licensed as a whole\nat no charge to all third parties under the terms of this License.\n\nc.  If the modified program normally reads commands  interactively  when  run,  you  must\ncause  it, when started running for such interactive use in the most ordinary way, to\nprint or display an announcement including an appropriate copyright notice and a  no‐\ntice that there is no warranty (or else, saying that you provide a warranty) and that\nusers  may  redistribute the program under these conditions, and telling the user how\nto view a copy of this License.  (Exception: if the Program itself is interactive but\ndoes not normally print such an announcement, your work based on the Program  is  not\nrequired to print an announcement.)\n\nThese  requirements  apply  to the modified work as a whole.  If identifiable sections of\nthat work are not derived from the Program, and can be reasonably considered  independent\nand separate works in themselves, then this License, and its terms, do not apply to those\nsections  when  you  distribute them as separate works.  But when you distribute the same\nsections as part of a whole which is a work based on the Program, the distribution of the\nwhole must be on the terms of this License, whose permissions for other licensees  extend\nto the entire whole, and thus to each and every part regardless of who wrote it.\n\nThus, it is not the intent of this section to claim rights or contest your rights to work\nwritten  entirely by you; rather, the intent is to exercise the right to control the dis‐\ntribution of derivative or collective works based on the Program.\n\nIn addition, mere aggregation of another work not based on the Program with  the  Program\n(or  with  a  work  based on the Program) on a volume of a storage or distribution medium\ndoes not bring the other work under the scope of this License.\n\n3.  You may copy and distribute the Program (or a work based on it, under Section 2)  in  ob‐\nject  code or executable form under the terms of Sections 1 and 2 above provided that you\nalso do one of the following:\n\na.  Accompany it with the complete corresponding machine-readable source code, which must\nbe distributed under the terms of Sections 1 and 2 above on a medium customarily used\nfor software interchange; or,\n\nb.  Accompany it with a written offer, valid for at least three years, to give any  third\nparty,  for a charge no more than your cost of physically performing source distribu‐\ntion, a complete machine-readable copy of the corresponding source code, to  be  dis‐\ntributed  under  the terms of Sections 1 and 2 above on a medium customarily used for\nsoftware interchange; or,\n\nc.  Accompany it with the information you received as to the offer to  distribute  corre‐\nsponding  source code.  (This alternative is allowed only for noncommercial distribu‐\ntion and only if you received the program in object code or executable form with such\nan offer, in accord with Subsection b above.)\n\nThe source code for a work means the preferred form of the work for making  modifications\nto  it.   For  an executable work, complete source code means all the source code for all\nmodules it contains, plus any associated interface definition  files,  plus  the  scripts\nused  to  control  compilation and installation of the executable.  However, as a special\nexception, the source code distributed need not include anything that  is  normally  dis‐\ntributed  (in  either source or binary form) with the major components (compiler, kernel,\nand so on) of the operating system on which the executable runs,  unless  that  component\nitself accompanies the executable.\n\nIf  distribution  of  executable or object code is made by offering access to copy from a\ndesignated place, then offering equivalent access to copy the source code from  the  same\nplace  counts  as distribution of the source code, even though third parties are not com‐\npelled to copy the source along with the object code.\n\n4.  You may not copy, modify, sublicense, or distribute the Program except as expressly  pro‐\nvided  under this License.  Any attempt otherwise to copy, modify, sublicense or distrib‐\nute the Program is void, and will automatically terminate your rights under this License.\nHowever, parties who have received copies, or rights, from you under  this  License  will\nnot have their licenses terminated so long as such parties remain in full compliance.\n\n5.  You  are  not  required  to  accept this License, since you have not signed it.  However,\nnothing else grants you permission to modify or distribute the Program or its  derivative\nworks.   These  actions  are prohibited by law if you do not accept this License.  There‐\nfore, by modifying or distributing the Program (or any work based on  the  Program),  you\nindicate  your  acceptance of this License to do so, and all its terms and conditions for\ncopying, distributing or modifying the Program or works based on it.\n\n6.  Each time you redistribute the Program (or any work based on the Program), the  recipient\nautomatically receives a license from the original licensor to copy, distribute or modify\nthe  Program  subject  to these terms and conditions.  You may not impose any further re‐\nstrictions on the recipients' exercise of the rights granted herein.  You are not respon‐\nsible for enforcing compliance by third parties to this License.\n\n7.  If, as a consequence of a court judgment or allegation of patent infringement or for  any\nother  reason  (not  limited to patent issues), conditions are imposed on you (whether by\ncourt order, agreement or otherwise) that contradict the conditions of this License, they\ndo not excuse you from the conditions of this License.  If you cannot distribute so as to\nsatisfy simultaneously your obligations under this License and any other pertinent oblig‐\nations, then as a consequence you may not distribute the Program at all.  For example, if\na patent license would not permit royalty-free redistribution of the Program by all those\nwho receive copies directly or indirectly through you, then the only way you  could  sat‐\nisfy  both it and this License would be to refrain entirely from distribution of the Pro‐\ngram.\n\nIf any portion of this section is held invalid or unenforceable under any particular cir‐\ncumstance, the balance of the section is intended to apply and the section as a whole  is\nintended to apply in other circumstances.\n\nIt  is  not  the  purpose  of this section to induce you to infringe any patents or other\nproperty right claims or to contest validity of any such claims;  this  section  has  the\nsole  purpose of protecting the integrity of the free software distribution system, which\nis implemented by public license practices.  Many people have made generous contributions\nto the wide range of software distributed through that system in reliance  on  consistent\napplication  of that system; it is up to the author/donor to decide if he or she is will‐\ning to distribute software through any other system and a  licensee  cannot  impose  that\nchoice.\n\nThis section is intended to make thoroughly clear what is believed to be a consequence of\nthe rest of this License.\n\n8.  If  the  distribution and/or use of the Program is restricted in certain countries either\nby patents or by copyrighted interfaces, the original copyright  holder  who  places  the\nProgram  under  this License may add an explicit geographical distribution limitation ex‐\ncluding those countries, so that distribution is permitted only in or among countries not\nthus excluded.  In such case, this License incorporates the limitation as if  written  in\nthe body of this License.\n\n9.  The  Free Software Foundation may publish revised and/or new versions of the General Pub‐\nlic License from time to time.  Such new versions  will  be  similar  in  spirit  to  the\npresent version, but may differ in detail to address new problems or concerns.\n\nEach  version  is given a distinguishing version number.  If the Program specifies a ver‐\nsion number of this License which applies to it and ``any later version'', you  have  the\noption  of following the terms and conditions either of that version or of any later ver‐\nsion published by the Free Software Foundation.  If the Program does not specify  a  ver‐\nsion  number of this License, you may choose any version ever published by the Free Soft‐\nware Foundation.\n\n10. If you wish to incorporate parts of the Program into other free programs whose  distribu‐\ntion  conditions  are different, write to the author to ask for permission.  For software\nwhich is copyrighted by the Free Software Foundation, write to the Free Software  Founda‐\ntion;  we  sometimes  make  exceptions  for this.  Our decision will be guided by the two\ngoals of preserving the free status of all derivatives of our free software and  of  pro‐\nmoting the sharing and reuse of software generally.\n\nNO WARRANTY\n\n11. BECAUSE  THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO\nTHE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN  OTHERWISE  STATED  IN  WRITING  THE\nCOPYRIGHT  HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM ``AS IS'' WITHOUT WARRANTY OF\nANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,  THE  IMPLIED  WAR‐\nRANTIES  OF  MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS TO\nTHE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE PROGRAM PROVE  DEFEC‐\nTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.\n\n12. IN  NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT\nHOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE  PROGRAM  AS  PERMITTED\nABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSE‐\nQUENTIAL  DAMAGES  ARISING  OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT\nNOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY  YOU\nOR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF\nSUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.\n\nEND OF TERMS AND CONDITIONS\n"

It is safest\nto attach them to the start of each source file to most effectively\nconvey the exclusion of warranty; and each file should have at least\nthe ``copyright'' line and a pointer to where the full notice is found.\n\n<one line to give the program's name and a brief idea of what it does.>\nCopyright (C) <year>  <name of author>\n\nThis program is free software; you can redistribute it and/or modify\nit under the terms of the GNU General Public License as published by\nthe Free Software Foundation; either version 2 of the License, or\n(at your option) any later version.\n\nThis program is distributed in the hope that it will be useful,\nbut WITHOUT ANY WARRANTY; without even the implied warranty of\nMERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
