     2: 		       Version 2, June 1991

     5:  51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
     6:  Everyone is permitted to copy and distribute verbatim copies
     7:  of this license document, but changing it is not allowed.
     8: 
     9: 			    Preamble
    10: 
    11:   The licenses for most software are designed to take away your
    12: freedom to share and change it.  By contrast, the GNU General Public
    13: License is intended to guarantee your freedom to share and change free
    14: software--to make sure the software is free for all its users.  This
    15: General Public License applies to most of the Free Software
    16: Foundation's software and to any other program whose authors commit to
    17: using it.  (Some other Free Software Foundation software is covered by
    18: the GNU Lesser General Public License instead.)  You can apply it to
    19: your programs, too.
    20: 
    21:   When we speak of free software, we are referring to freedom, not
    22: price.  Our General Public Licenses are designed to make sure that you
    23: have the freedom to distribute copies of free software (and charge for
    24: this service if you wish), that you receive source code or can get it
    25: if you want it, that you can change the software or use pieces of it
    26: in new free programs; and that you know you can do these things.
    27: 
    28:   To protect your rights, we need to make restrictions that forbid
    29: anyone to deny you these rights or to ask you to surrender the rights.
    30: These restrictions translate to certain responsibilities for you if you
    31: distribute copies of the software, or if you modify it.
    32: 
    33:   For example, if you distribute copies of such a program, whether
    34: gratis or for a fee, you must give the recipients all the rights that
    35: you have.  You must make sure that they, too, receive or can get the
    36: source code.  And you must show them these terms so they know their
    37: rights.
    38: 
    39:   We protect your rights with two steps: (1) copyright the software, and
    40: (2) offer you this license which gives you legal permission to copy,
    41: distribute and/or modify the software.
    42: 
    43:   Also, for each author's protection and ours, we want to make certain
    44: that everyone understands that there is no warranty for this free
    45: software.  If the software is modified by someone else and passed on, we
    46: want its recipients to know that what they have is not the original, so
    47: that any problems introduced by others will not reflect on the original
    48: authors' reputations.
    49: 
    50:   Finally, any free program is threatened constantly by software
    51: patents.  We wish to avoid the danger that redistributors of a free
    52: program will individually obtain patent licenses, in effect making the
    53: program proprietary.  To prevent this, we have made it clear that any
    54: patent must be licensed for everyone's free use or not licensed at all.
    55: 
    56:   The precise terms and conditions for copying, distribution and
    57: modification follow.
    58: 
    59: 		    GNU GENERAL PUBLIC LICENSE
    60:    TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
    61: 
    62:   0. This License applies to any program or other work which contains
    63: a notice placed by the copyright holder saying it may be distributed
    64: under the terms of this General Public License.  The "Program", below,
    65: refers to any such program or work, and a "work based on the Program"
    66: means either the Program or any derivative work under copyright law:
    67: that is to say, a work containing the Program or a portion of it,
    68: either verbatim or with modifications and/or translated into another
    69: language.  (Hereinafter, translation is included without limitation in
    70: the term "modification".)  Each licensee is addressed as "you".
    71: 
    72: Activities other than copying, distribution and modification are not
    73: covered by this License; they are outside its scope.  The act of
    74: running the Program is not restricted, and the output from the Program
    75: is covered only if its contents constitute a work based on the
    76: Program (independent of having been made by running the Program).
    77: Whether that is true depends on what the Program does.
    78: 
    79:   1. You may copy and distribute verbatim copies of the Program's
    80: source code as you receive it, in any medium, provided that you
    81: conspicuously and appropriately publish on each copy an appropriate
    82: copyright notice and disclaimer of warranty; keep intact all the
    83: notices that refer to this License and to the absence of any warranty;
    84: and give any other recipients of the Program a copy of this License
    85: along with the Program.
    86: 
    87: You may charge a fee for the physical act of transferring a copy, and
    88: you may at your option offer warranty protection in exchange for a fee.
    89: 
    90:   2. You may modify your copy or copies of the Program or any portion
    91: of it, thus forming a work based on the Program, and copy and
    92: distribute such modifications or work under the terms of Section 1
    93: above, provided that you also meet all of these conditions:
    94: 
    95:     a) You must cause the modified files to carry prominent notices
    96:     stating that you changed the files and the date of any change.
    97: 
    98:     b) You must cause any work that you distribute or publish, that in
    99:     whole or in part contains or is derived from the Program or any
   100:     part thereof, to be licensed as a whole at no charge to all third
   101:     parties under the terms of this License.
   102: 
   103:     c) If the modified program normally reads commands interactively
   104:     when run, you must cause it, when started running for such
   105:     interactive use in the most ordinary way, to print or display an
   106:     announcement including an appropriate copyright notice and a
   107:     notice that there is no warranty (or else, saying that you provide
   108:     a warranty) and that users may redistribute the program under
   109:     these conditions, and telling the user how to view a copy of this
   110:     License.  (Exception: if the Program itself is interactive but
   111:     does not normally print such an announcement, your work based on
   112:     the Program is not required to print an announcement.)
   113: 
   114: These requirements apply to the modified work as a whole.  If
   115: identifiable sections of that work are not derived from the Program,
   116: and can be reasonably considered independent and separate works in
   117: themselves, then this License, and its terms, do not apply to those
   118: sections when you distribute them as separate works.  But when you
   119: distribute the same sections as part of a whole which is a work based
   120: on the Program, the distribution of the whole must be on the terms of
   121: this License, whose permissions for other licensees extend to the
   122: entire whole, and thus to each and every part regardless of who wrote it.
   123: 
   124: Thus, it is not the intent of this section to claim rights or contest
   125: your rights to work written entirely by you; rather, the intent is to
   126: exercise the right to control the distribution of derivative or
   127: collective works based on the Program.
   128: 
   129: In addition, mere aggregation of another work not based on the Program
   130: with the Program (or with a work based on the Program) on a volume of
   131: a storage or distribution medium does not bring the other work under
   132: the scope of this License.
   133: 
   134:   3. You may copy and distribute the Program (or a work based on it,
   135: under Section 2) in object code or executable form under the terms of
   136: Sections 1 and 2 above provided that you also do one of the following:
   137: 
   138:     a) Accompany it with the complete corresponding machine-readable
   139:     source code, which must be distributed under the terms of Sections
   140:     1 and 2 above on a medium customarily used for software interchange; or,
   141: 
   142:     b) Accompany it with a written offer, valid for at least three
   143:     years, to give any third party, for a charge no more than your
   144:     cost of physically performing source distribution, a complete
   145:     machine-readable copy of the corresponding source code, to be
   146:     distributed under the terms of Sections 1 and 2 above on a medium
   147:     customarily used for software interchange; or,
   148: 
   149:     c) Accompany it with the information you received as to the offer
   150:     to distribute corresponding source code.  (This alternative is
   151:     allowed only for noncommercial distribution and only if you
   152:     received the program in object code or executable form with such
   153:     an offer, in accord with Subsection b above.)
   154: 
   155: The source code for a work means the preferred form of the work for
   156: making modifications to it.  For an executable work, complete source
   157: code means all the source code for all modules it contains, plus any
   158: associated interface definition files, plus the scripts used to
   159: control compilation and installation of the executable.  However, as a
   160: special exception, the source code distributed need not include
   161: anything that is normally distributed (in either source or binary
   162: form) with the major components (compiler, kernel, and so on) of the
   163: operating system on which the executable runs, unless that component
   164: itself accompanies the executable.
   165: 
   166: If distribution of executable or object code is made by offering
   167: access to copy from a designated place, then offering equivalent
   168: access to copy the source code from the same place counts as
   169: distribution of the source code, even though third parties are not
   170: compelled to copy the source along with the object code.
   171: 
   172:   4. You may not copy, modify, sublicense, or distribute the Program
   173: except as expressly provided under this License.  Any attempt
   174: otherwise to copy, modify, sublicense or distribute the Program is
   175: void, and will automatically terminate your rights under this License.
   176: However, parties who have received copies, or rights, from you under
   177: this License will not have their licenses terminated so long as such
   178: parties remain in full compliance.
   179: 
   180:   5. You are not required to accept this License, since you have not
   181: signed it.  However, nothing else grants you permission to modify or
   182: distribute the Program or its derivative works.  These actions are
   183: prohibited by law if you do not accept this License.  Therefore, by
   184: modifying or distributing the Program (or any work based on the
   185: Program), you indicate your acceptance of this License to do so, and
   186: all its terms and conditions for copying, distributing or modifying
   187: the Program or works based on it.
   188: 
   189:   6. Each time you redistribute the Program (or any work based on the
   190: Program), the recipient automatically receives a license from the
   191: original licensor to copy, distribute or modify the Program subject to
   192: these terms and conditions.  You may not impose any further
   193: restrictions on the recipients' exercise of the rights granted herein.
   194: You are not responsible for enforcing compliance by third parties to
   195: this License.
   196: 
   197:   7. If, as a consequence of a court judgment or allegation of patent
   198: infringement or for any other reason (not limited to patent issues),
   199: conditions are imposed on you (whether by court order, agreement or
   200: otherwise) that contradict the conditions of this License, they do not
   201: excuse you from the conditions of this License.  If you cannot
   202: distribute so as to satisfy simultaneously your obligations under this
   203: License and any other pertinent obligations, then as a consequence you
   204: may not distribute the Program at all.  For example, if a patent
   205: license would not permit royalty-free redistribution of the Program by
   206: all those who receive copies directly or indirectly through you, then
   207: the only way you could satisfy both it and this License would be to
   208: refrain entirely from distribution of the Program.
   209: 
   210: If any portion of this section is held invalid or unenforceable under
   211: any particular circumstance, the balance of the section is intended to
   212: apply and the section as a whole is intended to apply in other
   213: circumstances.
   214: 
   215: It is not the purpose of this section to induce you to infringe any
   216: patents or other property right claims or to contest validity of any
   217: such claims; this section has the sole purpose of protecting the
   218: integrity of the free software distribution system, which is
   219: implemented by public license practices.  Many people have made
   220: generous contributions to the wide range of software distributed
   221: through that system in reliance on consistent application of that
   222: system; it is up to the author/donor to decide if he or she is willing
   223: to distribute software through any other system and a licensee cannot
   224: impose that choice.
   225: 
   226: This section is intended to make thoroughly clear what is believed to
   227: be a consequence of the rest of this License.
   228: 
   229:   8. If the distribution and/or use of the Program is restricted in
   230: certain countries either by patents or by copyrighted interfaces, the
   231: original copyright holder who places the Program under this License
   232: may add an explicit geographical distribution limitation excluding
   233: those countries, so that distribution is permitted only in or among
   234: countries not thus excluded.  In such case, this License incorporates
   235: the limitation as if written in the body of this License.
   236: 
   237:   9. The Free Software Foundation may publish revised and/or new versions
   238: of the General Public License from time to time.  Such new versions will
   239: be similar in spirit to the present version, but may differ in detail to
   240: address new problems or concerns.
   241: 
   242: Each version is given a distinguishing version number.  If the Program
   243: specifies a version number of this License which applies to it and "any
   244: later version", you have the option of following the terms and conditions
   245: either of that version or of any later version published by the Free
   246: Software Foundation.  If the Program does not specify a version number of
   247: this License, you may choose any version ever published by the Free Software
   248: Foundation.
   249: 
   250:   10. If you wish to incorporate parts of the Program into other free
   251: programs whose distribution conditions are different, write to the author
   252: to ask for permission.  For software which is copyrighted by the Free
   253: Software Foundation, write to the Free Software Foundation; we sometimes
   254: make exceptions for this.  Our decision will be guided by the two goals
   255: of preserving the free status of all derivatives of our free software and
   256: of promoting the sharing and reuse of software generally.
   257: 
   258: 			    NO WARRANTY
   259: 
   260:   11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
   261: FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
   262: OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
   263: PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
   264: OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
   265: MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
   266: TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
   267: PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
   268: REPAIR OR CORRECTION.
   269: 
   270:   12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
   271: WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
   272: REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
   273: INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
   274: OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
   275: TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
   276: YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
   277: PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
   278: POSSIBILITY OF SUCH DAMAGES.
   279: 
   280: 		     END OF TERMS AND CONDITIONS
   281: 
   282: 	    How to Apply These Terms to Your New Programs
   283: 
   284:   If you develop a new program, and you want it to be of the greatest
   285: possible use to the public, the best way to achieve this is to make it
   286: free software which everyone can redistribute and change under these terms.
   287: 
   288:   To do so, attach the following notices to the program.  It is safest
   289: to attach them to the start of each source file to most effectively
   290: convey the exclusion of warranty; and each file should have at least
   291: the "copyright" line and a pointer to where the full notice is found.
   292: 
   293:     <one line to give the program's name and a brief idea of what it does.>
   294:     Copyright (C) <year>  <name of author>
   295: 
   296:     This program is free software; you can redistribute it and/or modify
   297:     it under the terms of the GNU General Public License as published by
   298:     the Free Software Foundation; either version 2 of the License, or
   299:     (at your option) any later version.
   300: 
   301:     This program is distributed in the hope that it will be useful,
   302:     but WITHOUT ANY WARRANTY; without even the implied warranty of
   303:     MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
   304:     GNU General Public License for more details.
   305: 
   306:     You should have received a copy of the GNU General Public License along
   307:     with this program; if not, write to the Free Software Foundation, Inc.,
   308:     51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
   309: 
   310: Also add information on how to contact you by electronic and paper mail.
   311: 
   312: If the program is interactive, make it output a short notice like this
   313: when it starts in an interactive mode:
   314: 
   315:     Gnomovision version 69, Copyright (C) year name of author
   316:     Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
   317:     This is free software, and you are welcome to redistribute it
   318:     under certain conditions; type `show c' for details.
   319: 
   320: The hypothetical commands `show w' and `show c' should show the appropriate
   321: parts of the General Public License.  Of course, the commands you use may
   322: be called something other than `show w' and `show c'; they could even be
   323: mouse-clicks or menu items--whatever suits your program.
   324: 
   325: You should also get your employer (if you work as a programmer) or your
   326: school, if any, to sign a "copyright disclaimer" for the program, if
   327: necessary.  Here is a sample; alter the names:
   328: 
   329:   Yoyodyne, Inc., hereby disclaims all copyright interest in the program
   330:   `Gnomovision' (which makes passes at compilers) written by James Hacker.

   332:   <signature of Ty Coon>, 1 April 1989
   333:   Ty Coon, President of Vice
   334: 
   335: This General Public License does not permit incorporating your program into
   336: proprietary programs.  If your program is a subroutine library, you may
   337: consider it more useful to permit linking proprietary applications with the
   338: library.  If this is what you want to do, use the GNU Lesser General
   339: Public License instead of this License.
