   14: @unnumberedsec Preamble
   15: 
   16:   The licenses for most software are designed to take away your
   17: freedom to share and change it.  By contrast, the GNU General Public
   18: License is intended to guarantee your freedom to share and change free
   19: software---to make sure the software is free for all its users.  This
   20: General Public License applies to most of the Free Software
   21: Foundation's software and to any other program whose authors commit to
   22: using it.  (Some other Free Software Foundation software is covered by
   23: the GNU Library General Public License instead.)  You can apply it to
   24: your programs, too.
   25: 
   26:   When we speak of free software, we are referring to freedom, not
   27: price.  Our General Public Licenses are designed to make sure that you
   28: have the freedom to distribute copies of free software (and charge for
   29: this service if you wish), that you receive source code or can get it
   30: if you want it, that you can change the software or use pieces of it
   31: in new free programs; and that you know you can do these things.
   32: 
   33:   To protect your rights, we need to make restrictions that forbid
   34: anyone to deny you these rights or to ask you to surrender the rights.
   35: These restrictions translate to certain responsibilities for you if you
   36: distribute copies of the software, or if you modify it.
   37: 
   38:   For example, if you distribute copies of such a program, whether
   39: gratis or for a fee, you must give the recipients all the rights that
   40: you have.  You must make sure that they, too, receive or can get the
   41: source code.  And you must show them these terms so they know their
   42: rights.
   43: 
   44:   We protect your rights with two steps: (1) copyright the software, and
   45: (2) offer you this license which gives you legal permission to copy,
   46: distribute and/or modify the software.
   47: 
   48:   Also, for each author's protection and ours, we want to make certain
   49: that everyone understands that there is no warranty for this free
   50: software.  If the software is modified by someone else and passed on, we
   51: want its recipients to know that what they have is not the original, so
   52: that any problems introduced by others will not reflect on the original
   53: authors' reputations.
   54: 
   55:   Finally, any free program is threatened constantly by software
   56: patents.  We wish to avoid the danger that redistributors of a free
   57: program will individually obtain patent licenses, in effect making the
   58: program proprietary.  To prevent this, we have made it clear that any
   59: patent must be licensed for everyone's free use or not licensed at all.
   60: 
   61:   The precise terms and conditions for copying, distribution and
   62: modification follow.

   69: @end ifinfo
   70: 
   71: @enumerate
   72: @item
   73: This License applies to any program or other work which contains
   74: a notice placed by the copyright holder saying it may be distributed
   75: under the terms of this General Public License.  The ``Program'', below,
   76: refers to any such program or work, and a ``work based on the Program''
   77: means either the Program or any derivative work under copyright law:
   78: that is to say, a work containing the Program or a portion of it,
   79: either verbatim or with modifications and/or translated into another
   80: language.  (Hereinafter, translation is included without limitation in
   81: the term ``modification''.)  Each licensee is addressed as ``you''.
   82: 
   83: Activities other than copying, distribution and modification are not
   84: covered by this License; they are outside its scope.  The act of
   85: running the Program is not restricted, and the output from the Program
   86: is covered only if its contents constitute a work based on the
   87: Program (independent of having been made by running the Program).
   88: Whether that is true depends on what the Program does.
   89: 
   90: @item
   91: You may copy and distribute verbatim copies of the Program's
   92: source code as you receive it, in any medium, provided that you
   93: conspicuously and appropriately publish on each copy an appropriate
   94: copyright notice and disclaimer of warranty; keep intact all the
   95: notices that refer to this License and to the absence of any warranty;
   96: and give any other recipients of the Program a copy of this License
   97: along with the Program.
   98: 
   99: You may charge a fee for the physical act of transferring a copy, and
  100: you may at your option offer warranty protection in exchange for a fee.
  101: 
  102: @item
  103: You may modify your copy or copies of the Program or any portion
  104: of it, thus forming a work based on the Program, and copy and
  105: distribute such modifications or work under the terms of Section 1
  106: above, provided that you also meet all of these conditions:
  107: 
  108: @enumerate a
  109: @item
  110: You must cause the modified files to carry prominent notices
  111: stating that you changed the files and the date of any change.
  112: 
  113: @item
  114: You must cause any work that you distribute or publish, that in
  115: whole or in part contains or is derived from the Program or any
  116: part thereof, to be licensed as a whole at no charge to all third
  117: parties under the terms of this License.
  118: 
  119: @item
  120: If the modified program normally reads commands interactively
  121: when run, you must cause it, when started running for such
  122: interactive use in the most ordinary way, to print or display an
  123: announcement including an appropriate copyright notice and a
  124: notice that there is no warranty (or else, saying that you provide
  125: a warranty) and that users may redistribute the program under
  126: these conditions, and telling the user how to view a copy of this
  127: License.  (Exception: if the Program itself is interactive but
  128: does not normally print such an announcement, your work based on
  129: the Program is not required to print an announcement.)
  130: @end enumerate
  131: 
  132: These requirements apply to the modified work as a whole.  If
  133: identifiable sections of that work are not derived from the Program,
  134: and can be reasonably considered independent and separate works in
  135: themselves, then this License, and its terms, do not apply to those
  136: sections when you distribute them as separate works.  But when you
  137: distribute the same sections as part of a whole which is a work based
  138: on the Program, the distribution of the whole must be on the terms of
  139: this License, whose permissions for other licensees extend to the
  140: entire whole, and thus to each and every part regardless of who wrote it.
  141: 
  142: Thus, it is not the intent of this section to claim rights or contest
  143: your rights to work written entirely by you; rather, the intent is to
  144: exercise the right to control the distribution of derivative or
  145: collective works based on the Program.
  146: 
  147: In addition, mere aggregation of another work not based on the Program
  148: with the Program (or with a work based on the Program) on a volume of
  149: a storage or distribution medium does not bring the other work under
  150: the scope of this License.
  151: 
  152: @item
  153: You may copy and distribute the Program (or a work based on it,
  154: under Section 2) in object code or executable form under the terms of
  155: Sections 1 and 2 above provided that you also do one of the following:
  156: 
  157: @enumerate a
  158: @item
  159: Accompany it with the complete corresponding machine-readable
  160: source code, which must be distributed under the terms of Sections
  161: 1 and 2 above on a medium customarily used for software interchange; or,
  162: 
  163: @item
  164: Accompany it with a written offer, valid for at least three
  165: years, to give any third party, for a charge no more than your
  166: cost of physically performing source distribution, a complete
  167: machine-readable copy of the corresponding source code, to be
  168: distributed under the terms of Sections 1 and 2 above on a medium
  169: customarily used for software interchange; or,
  170: 
  171: @item
  172: Accompany it with the information you received as to the offer
  173: to distribute corresponding source code.  (This alternative is
  174: allowed only for noncommercial distribution and only if you
  175: received the program in object code or executable form with such
  176: an offer, in accord with Subsection b above.)
  177: @end enumerate
  178: 
  179: The source code for a work means the preferred form of the work for
  180: making modifications to it.  For an executable work, complete source
  181: code means all the source code for all modules it contains, plus any
  182: associated interface definition files, plus the scripts used to
  183: control compilation and installation of the executable.  However, as a
  184: special exception, the source code distributed need not include
  185: anything that is normally distributed (in either source or binary
  186: form) with the major components (compiler, kernel, and so on) of the
  187: operating system on which the executable runs, unless that component
  188: itself accompanies the executable.
  189: 
  190: If distribution of executable or object code is made by offering
  191: access to copy from a designated place, then offering equivalent
  192: access to copy the source code from the same place counts as
  193: distribution of the source code, even though third parties are not
  194: compelled to copy the source along with the object code.
  195: 
  196: @item
  197: You may not copy, modify, sublicense, or distribute the Program
  198: except as expressly provided under this License.  Any attempt
  199: otherwise to copy, modify, sublicense or distribute the Program is
  200: void, and will automatically terminate your rights under this License.
  201: However, parties who have received copies, or rights, from you under
  202: this License will not have their licenses terminated so long as such
  203: parties remain in full compliance.
  204: 
  205: @item
  206: You are not required to accept this License, since you have not
  207: signed it.  However, nothing else grants you permission to modify or
  208: distribute the Program or its derivative works.  These actions are
  209: prohibited by law if you do not accept this License.  Therefore, by
  210: modifying or distributing the Program (or any work based on the
  211: Program), you indicate your acceptance of this License to do so, and
  212: all its terms and conditions for copying, distributing or modifying
  213: the Program or works based on it.
  214: 
  215: @item
  216: Each time you redistribute the Program (or any work based on the
  217: Program), the recipient automatically receives a license from the
  218: original licensor to copy, distribute or modify the Program subject to
  219: these terms and conditions.  You may not impose any further
  220: restrictions on the recipients' exercise of the rights granted herein.
  221: You are not responsible for enforcing compliance by third parties to
  222: this License.
  223: 
  224: @item
  225: If, as a consequence of a court judgment or allegation of patent
  226: infringement or for any other reason (not limited to patent issues),
  227: conditions are imposed on you (whether by court order, agreement or
  228: otherwise) that contradict the conditions of this License, they do not
  229: excuse you from the conditions of this License.  If you cannot
  230: distribute so as to satisfy simultaneously your obligations under this
  231: License and any other pertinent obligations, then as a consequence you
  232: may not distribute the Program at all.  For example, if a patent
  233: license would not permit royalty-free redistribution of the Program by
  234: all those who receive copies directly or indirectly through you, then
  235: the only way you could satisfy both it and this License would be to
  236: refrain entirely from distribution of the Program.
  237: 
  238: If any portion of this section is held invalid or unenforceable under
  239: any particular circumstance, the balance of the section is intended to
  240: apply and the section as a whole is intended to apply in other
  241: circumstances.
  242: 
  243: It is not the purpose of this section to induce you to infringe any
  244: patents or other property right claims or to contest validity of any
  245: such claims; this section has the sole purpose of protecting the
  246: integrity of the free software distribution system, which is
  247: implemented by public license practices.  Many people have made
  248: generous contributions to the wide range of software distributed
  249: through that system in reliance on consistent application of that
  250: system; it is up to the author/donor to decide if he or she is willing
  251: to distribute software through any other system and a licensee cannot
  252: impose that choice.
  253: 
  254: This section is intended to make thoroughly clear what is believed to
  255: be a consequence of the rest of this License.
  256: 
  257: @item
  258: If the distribution and/or use of the Program is restricted in
  259: certain countries either by patents or by copyrighted interfaces, the
  260: original copyright holder who places the Program under this License
  261: may add an explicit geographical distribution limitation excluding
  262: those countries, so that distribution is permitted only in or among
  263: countries not thus excluded.  In such case, this License incorporates
  264: the limitation as if written in the body of this License.
  265: 
  266: @item
  267: The Free Software Foundation may publish revised and/or new versions
  268: of the General Public License from time to time.  Such new versions will
  269: be similar in spirit to the present version, but may differ in detail to
  270: address new problems or concerns.
  271: 
  272: Each version is given a distinguishing version number.  If the Program
  273: specifies a version number of this License which applies to it and ``any
  274: later version'', you have the option of following the terms and conditions
  275: either of that version or of any later version published by the Free
  276: Software Foundation.  If the Program does not specify a version number of
  277: this License, you may choose any version ever published by the Free Software
  278: Foundation.
  279: 
  280: @item
  281: If you wish to incorporate parts of the Program into other free
  282: programs whose distribution conditions are different, write to the author
  283: to ask for permission.  For software which is copyrighted by the Free
  284: Software Foundation, write to the Free Software Foundation; we sometimes
  285: make exceptions for this.  Our decision will be guided by the two goals
  286: of preserving the free status of all derivatives of our free software and
  287: of promoting the sharing and reuse of software generally.

  327: @unnumberedsec How to Apply These Terms to Your New Programs
  328: 
  329:   If you develop a new program, and you want it to be of the greatest
  330: possible use to the public, the best way to achieve this is to make it
  331: free software which everyone can redistribute and change under these terms.
  332: 
  333:   To do so, attach the following notices to the program.  It is safest
  334: to attach them to the start of each source file to most effectively
  335: convey the exclusion of warranty; and each file should have at least
  336: the ``copyright'' line and a pointer to where the full notice is found.
