   18:  Everyone is permitted to copy and distribute verbatim copies
   19:  of this license document, but changing it is not allowed.

   21: 			    Preamble
   22: 
   23:   The licenses for most software are designed to take away your
   24: freedom to share and change it.  By contrast, the GNU General Public
   25: License is intended to guarantee your freedom to share and change free
   26: software--to make sure the software is free for all its users.  This
   27: General Public License applies to most of the Free Software
   28: Foundation's software and to any other program whose authors commit to
   29: using it.  (Some other Free Software Foundation software is covered by
   30: the GNU Library General Public License instead.)  You can apply it to
   31: your programs, too.
   32: 
   33:   When we speak of free software, we are referring to freedom, not
   34: price.  Our General Public Licenses are designed to make sure that you
   35: have the freedom to distribute copies of free software (and charge for
   36: this service if you wish), that you receive source code or can get it
   37: if you want it, that you can change the software or use pieces of it
   38: in new free programs; and that you know you can do these things.
   39: 
   40:   To protect your rights, we need to make restrictions that forbid
   41: anyone to deny you these rights or to ask you to surrender the rights.
   42: These restrictions translate to certain responsibilities for you if you
   43: distribute copies of the software, or if you modify it.
   44: 
   45:   For example, if you distribute copies of such a program, whether
   46: gratis or for a fee, you must give the recipients all the rights that
   47: you have.  You must make sure that they, too, receive or can get the
   48: source code.  And you must show them these terms so they know their
   49: rights.
   50: 
   51:   We protect your rights with two steps: (1) copyright the software, and
   52: (2) offer you this license which gives you legal permission to copy,
   53: distribute and/or modify the software.
   54: 
   55:   Also, for each author's protection and ours, we want to make certain
   56: that everyone understands that there is no warranty for this free
   57: software.  If the software is modified by someone else and passed on, we
   58: want its recipients to know that what they have is not the original, so
   59: that any problems introduced by others will not reflect on the original
   60: authors' reputations.
   61: 
   62:   Finally, any free program is threatened constantly by software
   63: patents.  We wish to avoid the danger that redistributors of a free
   64: program will individually obtain patent licenses, in effect making the
   65: program proprietary.  To prevent this, we have made it clear that any
   66: patent must be licensed for everyone's free use or not licensed at all.
   67: 
   68:   The precise terms and conditions for copying, distribution and
   69: modification follow.
   70: 
   71: 		    GNU GENERAL PUBLIC LICENSE
   72:    TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
   73: 
   74:   0. This License applies to any program or other work which contains
   75: a notice placed by the copyright holder saying it may be distributed
   76: under the terms of this General Public License.  The "Program", below,
   77: refers to any such program or work, and a "work based on the Program"
   78: means either the Program or any derivative work under copyright law:
   79: that is to say, a work containing the Program or a portion of it,
   80: either verbatim or with modifications and/or translated into another
   81: language.  (Hereinafter, translation is included without limitation in
   82: the term "modification".)  Each licensee is addressed as "you".
   83: 
   84: Activities other than copying, distribution and modification are not
   85: covered by this License; they are outside its scope.  The act of
   86: running the Program is not restricted, and the output from the Program
   87: is covered only if its contents constitute a work based on the
   88: Program (independent of having been made by running the Program).
   89: Whether that is true depends on what the Program does.
   90: 
   91:   1. 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:   2. You may modify your copy or copies of the Program or any portion
  103: of it, thus forming a work based on the Program, and copy and
  104: distribute such modifications or work under the terms of Section 1
  105: above, provided that you also meet all of these conditions:
  106: 
  107:     a) You must cause the modified files to carry prominent notices
  108:     stating that you changed the files and the date of any change.
  109: 
  110:     b) You must cause any work that you distribute or publish, that in
  111:     whole or in part contains or is derived from the Program or any
  112:     part thereof, to be licensed as a whole at no charge to all third
  113:     parties under the terms of this License.
  114: 
  115:     c) If the modified program normally reads commands interactively
  116:     when run, you must cause it, when started running for such
  117:     interactive use in the most ordinary way, to print or display an
  118:     announcement including an appropriate copyright notice and a
  119:     notice that there is no warranty (or else, saying that you provide
  120:     a warranty) and that users may redistribute the program under
  121:     these conditions, and telling the user how to view a copy of this
  122:     License.  (Exception: if the Program itself is interactive but
  123:     does not normally print such an announcement, your work based on
  124:     the Program is not required to print an announcement.)
  125: 
  126: These requirements apply to the modified work as a whole.  If
  127: identifiable sections of that work are not derived from the Program,
  128: and can be reasonably considered independent and separate works in
  129: themselves, then this License, and its terms, do not apply to those
  130: sections when you distribute them as separate works.  But when you
  131: distribute the same sections as part of a whole which is a work based
  132: on the Program, the distribution of the whole must be on the terms of
  133: this License, whose permissions for other licensees extend to the
  134: entire whole, and thus to each and every part regardless of who wrote it.
  135: 
  136: Thus, it is not the intent of this section to claim rights or contest
  137: your rights to work written entirely by you; rather, the intent is to
  138: exercise the right to control the distribution of derivative or
  139: collective works based on the Program.
  140: 
  141: In addition, mere aggregation of another work not based on the Program
  142: with the Program (or with a work based on the Program) on a volume of
  143: a storage or distribution medium does not bring the other work under
  144: the scope of this License.
  145: 
  146:   3. You may copy and distribute the Program (or a work based on it,
  147: under Section 2) in object code or executable form under the terms of
  148: Sections 1 and 2 above provided that you also do one of the following:
  149: 
  150:     a) Accompany it with the complete corresponding machine-readable
  151:     source code, which must be distributed under the terms of Sections
  152:     1 and 2 above on a medium customarily used for software interchange; or,
  153: 
  154:     b) Accompany it with a written offer, valid for at least three
  155:     years, to give any third party, for a charge no more than your
  156:     cost of physically performing source distribution, a complete
  157:     machine-readable copy of the corresponding source code, to be
  158:     distributed under the terms of Sections 1 and 2 above on a medium
  159:     customarily used for software interchange; or,
  160: 
  161:     c) Accompany it with the information you received as to the offer
  162:     to distribute corresponding source code.  (This alternative is
  163:     allowed only for noncommercial distribution and only if you
  164:     received the program in object code or executable form with such
  165:     an offer, in accord with Subsection b above.)
  166: 
  167: The source code for a work means the preferred form of the work for
  168: making modifications to it.  For an executable work, complete source
  169: code means all the source code for all modules it contains, plus any
  170: associated interface definition files, plus the scripts used to
  171: control compilation and installation of the executable.  However, as a
  172: special exception, the source code distributed need not include
  173: anything that is normally distributed (in either source or binary
  174: form) with the major components (compiler, kernel, and so on) of the
  175: operating system on which the executable runs, unless that component
  176: itself accompanies the executable.
  177: 
  178: If distribution of executable or object code is made by offering
  179: access to copy from a designated place, then offering equivalent
  180: access to copy the source code from the same place counts as
  181: distribution of the source code, even though third parties are not
  182: compelled to copy the source along with the object code.
  183: 
  184:   4. You may not copy, modify, sublicense, or distribute the Program
  185: except as expressly provided under this License.  Any attempt
  186: otherwise to copy, modify, sublicense or distribute the Program is
  187: void, and will automatically terminate your rights under this License.
  188: However, parties who have received copies, or rights, from you under
  189: this License will not have their licenses terminated so long as such
  190: parties remain in full compliance.
  191: 
  192:   5. You are not required to accept this License, since you have not
  193: signed it.  However, nothing else grants you permission to modify or
  194: distribute the Program or its derivative works.  These actions are
  195: prohibited by law if you do not accept this License.  Therefore, by
  196: modifying or distributing the Program (or any work based on the
  197: Program), you indicate your acceptance of this License to do so, and
  198: all its terms and conditions for copying, distributing or modifying
  199: the Program or works based on it.
  200: 
  201:   6. Each time you redistribute the Program (or any work based on the
  202: Program), the recipient automatically receives a license from the
  203: original licensor to copy, distribute or modify the Program subject to
  204: these terms and conditions.  You may not impose any further
  205: restrictions on the recipients' exercise of the rights granted herein.
  206: You are not responsible for enforcing compliance by third parties to
  207: this License.
  208: 
  209:   7. If, as a consequence of a court judgment or allegation of patent
  210: infringement or for any other reason (not limited to patent issues),
  211: conditions are imposed on you (whether by court order, agreement or
  212: otherwise) that contradict the conditions of this License, they do not
  213: excuse you from the conditions of this License.  If you cannot
  214: distribute so as to satisfy simultaneously your obligations under this
  215: License and any other pertinent obligations, then as a consequence you
  216: may not distribute the Program at all.  For example, if a patent
  217: license would not permit royalty-free redistribution of the Program by
  218: all those who receive copies directly or indirectly through you, then
  219: the only way you could satisfy both it and this License would be to
  220: refrain entirely from distribution of the Program.
  221: 
  222: If any portion of this section is held invalid or unenforceable under
  223: any particular circumstance, the balance of the section is intended to
  224: apply and the section as a whole is intended to apply in other
  225: circumstances.
  226: 
  227: It is not the purpose of this section to induce you to infringe any
  228: patents or other property right claims or to contest validity of any
  229: such claims; this section has the sole purpose of protecting the
  230: integrity of the free software distribution system, which is
  231: implemented by public license practices.  Many people have made
  232: generous contributions to the wide range of software distributed
  233: through that system in reliance on consistent application of that
  234: system; it is up to the author/donor to decide if he or she is willing
  235: to distribute software through any other system and a licensee cannot
  236: impose that choice.
  237: 
  238: This section is intended to make thoroughly clear what is believed to
  239: be a consequence of the rest of this License.
  240: 
  241:   8. If the distribution and/or use of the Program is restricted in
  242: certain countries either by patents or by copyrighted interfaces, the
  243: original copyright holder who places the Program under this License
  244: may add an explicit geographical distribution limitation excluding
  245: those countries, so that distribution is permitted only in or among
  246: countries not thus excluded.  In such case, this License incorporates
  247: the limitation as if written in the body of this License.
  248: 
  249:   9. The Free Software Foundation may publish revised and/or new versions
  250: of the General Public License from time to time.  Such new versions will
  251: be similar in spirit to the present version, but may differ in detail to
  252: address new problems or concerns.
  253: 
  254: Each version is given a distinguishing version number.  If the Program
  255: specifies a version number of this License which applies to it and "any
  256: later version", you have the option of following the terms and conditions
  257: either of that version or of any later version published by the Free
  258: Software Foundation.  If the Program does not specify a version number of
  259: this License, you may choose any version ever published by the Free Software
  260: Foundation.
  261: 
  262:   10. If you wish to incorporate parts of the Program into other free
  263: programs whose distribution conditions are different, write to the author
  264: to ask for permission.  For software which is copyrighted by the Free
  265: Software Foundation, write to the Free Software Foundation; we sometimes
  266: make exceptions for this.  Our decision will be guided by the two goals
  267: of preserving the free status of all derivatives of our free software and
  268: of promoting the sharing and reuse of software generally.
  269: 
  270: 			    NO WARRANTY
  271: 
  272:   11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
  273: FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
  274: OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
  275: PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
  276: OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
  277: MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
  278: TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
  279: PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
  280: REPAIR OR CORRECTION.
  281: 
  282:   12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
  283: WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
  284: REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
  285: INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
  286: OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
  287: TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
  288: YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
  289: PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
  290: POSSIBILITY OF SUCH DAMAGES.
  291: 
  292: 		     END OF TERMS AND CONDITIONS
  293: 
  294: 	Appendix: How to Apply These Terms to Your New Programs
  295: 
  296:   If you develop a new program, and you want it to be of the greatest
  297: possible use to the public, the best way to achieve this is to make it
  298: free software which everyone can redistribute and change under these terms.
  299: 
  300:   To do so, attach the following notices to the program.  It is safest
  301: to attach them to the start of each source file to most effectively
  302: convey the exclusion of warranty; and each file should have at least
  303: the "copyright" line and a pointer to where the full notice is found.
  304: 
  305:     <one line to give the program's name and a brief idea of what it does.>
  306:     Copyright (C) 19yy  <name of author>
  307: 
  308:     This program is free software; you can redistribute it and/or modify
  309:     it under the terms of the GNU General Public License as published by
  310:     the Free Software Foundation; either version 2 of the License, or
  311:     (at your option) any later version.
  312: 
  313:     This program is distributed in the hope that it will be useful,
  314:     but WITHOUT ANY WARRANTY; without even the implied warranty of
  315:     MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
  316:     GNU General Public License for more details.
  317: 
  318:     You should have received a copy of the GNU General Public License
  319:     along with this program; if not, write to the Free Software
  320:     Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
  321: 
  322: Also add information on how to contact you by electronic and paper mail.
  323: 
  324: If the program is interactive, make it output a short notice like this
  325: when it starts in an interactive mode:
  326: 
  327:     Gnomovision version 69, Copyright (C) 19yy name of author
  328:     Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
  329:     This is free software, and you are welcome to redistribute it
  330:     under certain conditions; type `show c' for details.
  331: 
  332: The hypothetical commands `show w' and `show c' should show the appropriate
  333: parts of the General Public License.  Of course, the commands you use may
  334: be called something other than `show w' and `show c'; they could even be
  335: mouse-clicks or menu items--whatever suits your program.
  336: 
  337: You should also get your employer (if you work as a programmer) or your
  338: school, if any, to sign a "copyright disclaimer" for the program, if
  339: necessary.  Here is a sample; alter the names:
  340: 
  341:   Yoyodyne, Inc., hereby disclaims all copyright interest in the program
  342:   `Gnomovision' (which makes passes at compilers) written by James Hacker.
  343: 
  344:   <signature of Ty Coon>, 1 April 1989
  345:   Ty Coon, President of Vice
  346: 
  347: This General Public License does not permit incorporating your program into
  348: proprietary programs.  If your program is a subroutine library, you may
  349: consider it more useful to permit linking proprietary applications with the
  350: library.  If this is what you want to do, use the GNU Library General
  351: Public License instead of this License.
