   8                 Version 2, June 1991
   9  
  10   Copyright (C) 1989, 1991 Free Software Foundation, Inc.
  11                 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
  12   Everyone is permitted to copy and distribute verbatim copies
  13   of this license document, but changing it is not allowed.
  14  
  15                  Preamble
  16  
  17    The licenses for most software are designed to take away your
  18  freedom to share and change it.  By contrast, the GNU General Public
  19  License is intended to guarantee your freedom to share and change free
  20  software--to make sure the software is free for all its users.  This
  21  General Public License applies to most of the Free Software
  22  Foundation's software and to any other program whose authors commit to
  23  using it.  (Some other Free Software Foundation software is covered by
  24  the GNU Library General Public License instead.)  You can apply it to
  25  your programs, too.
  26  
  27    When we speak of free software, we are referring to freedom, not
  28  price.  Our General Public Licenses are designed to make sure that you
  29  have the freedom to distribute copies of free software (and charge for
  30  this service if you wish), that you receive source code or can get it
  31  if you want it, that you can change the software or use pieces of it
  32  in new free programs; and that you know you can do these things.
  33  
  34    To protect your rights, we need to make restrictions that forbid
  35  anyone to deny you these rights or to ask you to surrender the rights.
  36  These restrictions translate to certain responsibilities for you if you
  37  distribute copies of the software, or if you modify it.
  38  
  39    For example, if you distribute copies of such a program, whether
  40  gratis or for a fee, you must give the recipients all the rights that
  41  you have.  You must make sure that they, too, receive or can get the
  42  source code.  And you must show them these terms so they know their
  43  rights.
  44  
  45    We protect your rights with two steps: (1) copyright the software, and
  46  (2) offer you this license which gives you legal permission to copy,
  47  distribute and/or modify the software.
  48  
  49    Also, for each author's protection and ours, we want to make certain
  50  that everyone understands that there is no warranty for this free
  51  software.  If the software is modified by someone else and passed on, we
  52  want its recipients to know that what they have is not the original, so
  53  that any problems introduced by others will not reflect on the original
  54  authors' reputations.
  55  
  56    Finally, any free program is threatened constantly by software
  57  patents.  We wish to avoid the danger that redistributors of a free
  58  program will individually obtain patent licenses, in effect making the
  59  program proprietary.  To prevent this, we have made it clear that any
  60  patent must be licensed for everyone's free use or not licensed at all.
  61  
  62    The precise terms and conditions for copying, distribution and
  63  modification follow.
  64  
  65              GNU GENERAL PUBLIC LICENSE
  66     TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
  67  
  68    0. This License applies to any program or other work which contains
  69  a notice placed by the copyright holder saying it may be distributed
  70  under the terms of this General Public License.  The "Program", below,
  71  refers to any such program or work, and a "work based on the Program"
  72  means either the Program or any derivative work under copyright law:
  73  that is to say, a work containing the Program or a portion of it,
  74  either verbatim or with modifications and/or translated into another
  75  language.  (Hereinafter, translation is included without limitation in
  76  the term "modification".)  Each licensee is addressed as "you".
  77  
  78  Activities other than copying, distribution and modification are not
  79  covered by this License; they are outside its scope.  The act of
  80  running the Program is not restricted, and the output from the Program
  81  is covered only if its contents constitute a work based on the
  82  Program (independent of having been made by running the Program).
  83  Whether that is true depends on what the Program does.
  84  
  85    1. You may copy and distribute verbatim copies of the Program's
  86  source code as you receive it, in any medium, provided that you
  87  conspicuously and appropriately publish on each copy an appropriate
  88  copyright notice and disclaimer of warranty; keep intact all the
  89  notices that refer to this License and to the absence of any warranty;
  90  and give any other recipients of the Program a copy of this License
  91  along with the Program.
  92  
  93  You may charge a fee for the physical act of transferring a copy, and
  94  you may at your option offer warranty protection in exchange for a fee.
  95  
  96    2. You may modify your copy or copies of the Program or any portion
  97  of it, thus forming a work based on the Program, and copy and
  98  distribute such modifications or work under the terms of Section 1
  99  above, provided that you also meet all of these conditions:
 100  
 101      a) You must cause the modified files to carry prominent notices
 102      stating that you changed the files and the date of any change.
 103  
 104      b) You must cause any work that you distribute or publish, that in
 105      whole or in part contains or is derived from the Program or any
 106      part thereof, to be licensed as a whole at no charge to all third
 107      parties under the terms of this License.
 108  
 109      c) If the modified program normally reads commands interactively
 110      when run, you must cause it, when started running for such
 111      interactive use in the most ordinary way, to print or display an
 112      announcement including an appropriate copyright notice and a
 113      notice that there is no warranty (or else, saying that you provide
 114      a warranty) and that users may redistribute the program under
 115      these conditions, and telling the user how to view a copy of this
 116      License.  (Exception: if the Program itself is interactive but
 117      does not normally print such an announcement, your work based on
 118      the Program is not required to print an announcement.)
 119  
 120  These requirements apply to the modified work as a whole.  If
 121  identifiable sections of that work are not derived from the Program,
 122  and can be reasonably considered independent and separate works in
 123  themselves, then this License, and its terms, do not apply to those
 124  sections when you distribute them as separate works.  But when you
 125  distribute the same sections as part of a whole which is a work based
 126  on the Program, the distribution of the whole must be on the terms of
 127  this License, whose permissions for other licensees extend to the
 128  entire whole, and thus to each and every part regardless of who wrote it.
 129  
 130  Thus, it is not the intent of this section to claim rights or contest
 131  your rights to work written entirely by you; rather, the intent is to
 132  exercise the right to control the distribution of derivative or
 133  collective works based on the Program.
 134  
 135  In addition, mere aggregation of another work not based on the Program
 136  with the Program (or with a work based on the Program) on a volume of
 137  a storage or distribution medium does not bring the other work under
 138  the scope of this License.
 139  
 140    3. You may copy and distribute the Program (or a work based on it,
 141  under Section 2) in object code or executable form under the terms of
 142  Sections 1 and 2 above provided that you also do one of the following:
 143  
 144      a) Accompany it with the complete corresponding machine-readable
 145      source code, which must be distributed under the terms of Sections
 146      1 and 2 above on a medium customarily used for software interchange; or,
 147  
 148      b) Accompany it with a written offer, valid for at least three
 149      years, to give any third party, for a charge no more than your
 150      cost of physically performing source distribution, a complete
 151      machine-readable copy of the corresponding source code, to be
 152      distributed under the terms of Sections 1 and 2 above on a medium
 153      customarily used for software interchange; or,
 154  
 155      c) Accompany it with the information you received as to the offer
 156      to distribute corresponding source code.  (This alternative is
 157      allowed only for noncommercial distribution and only if you
 158      received the program in object code or executable form with such
 159      an offer, in accord with Subsection b above.)
 160  
 161  The source code for a work means the preferred form of the work for
 162  making modifications to it.  For an executable work, complete source
 163  code means all the source code for all modules it contains, plus any
 164  associated interface definition files, plus the scripts used to
 165  control compilation and installation of the executable.  However, as a
 166  special exception, the source code distributed need not include
 167  anything that is normally distributed (in either source or binary
 168  form) with the major components (compiler, kernel, and so on) of the
 169  operating system on which the executable runs, unless that component
 170  itself accompanies the executable.
 171  
 172  If distribution of executable or object code is made by offering
 173  access to copy from a designated place, then offering equivalent
 174  access to copy the source code from the same place counts as
 175  distribution of the source code, even though third parties are not
 176  compelled to copy the source along with the object code.
 177  
 178    4. You may not copy, modify, sublicense, or distribute the Program
 179  except as expressly provided under this License.  Any attempt
 180  otherwise to copy, modify, sublicense or distribute the Program is
 181  void, and will automatically terminate your rights under this License.
 182  However, parties who have received copies, or rights, from you under
 183  this License will not have their licenses terminated so long as such
 184  parties remain in full compliance.
 185  
 186    5. You are not required to accept this License, since you have not
 187  signed it.  However, nothing else grants you permission to modify or
 188  distribute the Program or its derivative works.  These actions are
 189  prohibited by law if you do not accept this License.  Therefore, by
 190  modifying or distributing the Program (or any work based on the
 191  Program), you indicate your acceptance of this License to do so, and
 192  all its terms and conditions for copying, distributing or modifying
 193  the Program or works based on it.
 194  
 195    6. Each time you redistribute the Program (or any work based on the
 196  Program), the recipient automatically receives a license from the
 197  original licensor to copy, distribute or modify the Program subject to
 198  these terms and conditions.  You may not impose any further
 199  restrictions on the recipients' exercise of the rights granted herein.
 200  You are not responsible for enforcing compliance by third parties to
 201  this License.
 202  
 203    7. If, as a consequence of a court judgment or allegation of patent
 204  infringement or for any other reason (not limited to patent issues),
 205  conditions are imposed on you (whether by court order, agreement or
 206  otherwise) that contradict the conditions of this License, they do not
 207  excuse you from the conditions of this License.  If you cannot
 208  distribute so as to satisfy simultaneously your obligations under this
 209  License and any other pertinent obligations, then as a consequence you
 210  may not distribute the Program at all.  For example, if a patent
 211  license would not permit royalty-free redistribution of the Program by
 212  all those who receive copies directly or indirectly through you, then
 213  the only way you could satisfy both it and this License would be to
 214  refrain entirely from distribution of the Program.
 215  
 216  If any portion of this section is held invalid or unenforceable under
 217  any particular circumstance, the balance of the section is intended to
 218  apply and the section as a whole is intended to apply in other
 219  circumstances.
 220  
 221  It is not the purpose of this section to induce you to infringe any
 222  patents or other property right claims or to contest validity of any
 223  such claims; this section has the sole purpose of protecting the
 224  integrity of the free software distribution system, which is
 225  implemented by public license practices.  Many people have made
 226  generous contributions to the wide range of software distributed
 227  through that system in reliance on consistent application of that
 228  system; it is up to the author/donor to decide if he or she is willing
 229  to distribute software through any other system and a licensee cannot
 230  impose that choice.
 231  
 232  This section is intended to make thoroughly clear what is believed to
 233  be a consequence of the rest of this License.
 234  
 235    8. If the distribution and/or use of the Program is restricted in
 236  certain countries either by patents or by copyrighted interfaces, the
 237  original copyright holder who places the Program under this License
 238  may add an explicit geographical distribution limitation excluding
 239  those countries, so that distribution is permitted only in or among
 240  countries not thus excluded.  In such case, this License incorporates
 241  the limitation as if written in the body of this License.
 242  
 243    9. The Free Software Foundation may publish revised and/or new versions
 244  of the General Public License from time to time.  Such new versions will
 245  be similar in spirit to the present version, but may differ in detail to
 246  address new problems or concerns.
 247  
 248  Each version is given a distinguishing version number.  If the Program
 249  specifies a version number of this License which applies to it and "any
 250  later version", you have the option of following the terms and conditions
 251  either of that version or of any later version published by the Free
 252  Software Foundation.  If the Program does not specify a version number of
 253  this License, you may choose any version ever published by the Free Software
 254  Foundation.
 255  
 256    10. If you wish to incorporate parts of the Program into other free
 257  programs whose distribution conditions are different, write to the author
 258  to ask for permission.  For software which is copyrighted by the Free
 259  Software Foundation, write to the Free Software Foundation; we sometimes
 260  make exceptions for this.  Our decision will be guided by the two goals
 261  of preserving the free status of all derivatives of our free software and
 262  of promoting the sharing and reuse of software generally.
 263  
 264                  NO WARRANTY
 265  
 266    11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
 267  FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
 268  OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
 269  PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
 270  OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
 271  MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
 272  TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
 273  PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
 274  REPAIR OR CORRECTION.
 275  
 276    12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
 277  WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
 278  REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
 279  INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
 280  OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
 281  TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
 282  YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
 283  PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
 284  POSSIBILITY OF SUCH DAMAGES.
 285  
 286               END OF TERMS AND CONDITIONS
 287  
 288          How to Apply These Terms to Your New Programs
 289  
 290    If you develop a new program, and you want it to be of the greatest
 291  possible use to the public, the best way to achieve this is to make it
 292  free software which everyone can redistribute and change under these terms.
 293  
 294    To do so, attach the following notices to the program.  It is safest
 295  to attach them to the start of each source file to most effectively
 296  convey the exclusion of warranty; and each file should have at least
 297  the "copyright" line and a pointer to where the full notice is found.
 298  
 299      <one line to give the program's name and a brief idea of what it does.>
 300      Copyright (C) 19yy  <name of author>
 301  
 302      This program is free software; you can redistribute it and/or modify
 303      it under the terms of the GNU General Public License as published by
 304      the Free Software Foundation; either version 2 of the License, or
 305      (at your option) any later version.
 306  
 307      This program is distributed in the hope that it will be useful,
 308      but WITHOUT ANY WARRANTY; without even the implied warranty of
 309      MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
 310      GNU General Public License for more details.
 311  
 312      You should have received a copy of the GNU General Public License
 313      along with this program; if not, write to the Free Software
 314      Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
 315  
 316  
 317  Also add information on how to contact you by electronic and paper mail.
 318  
 319  If the program is interactive, make it output a short notice like this
 320  when it starts in an interactive mode:
 321  
 322      Gnomovision version 69, Copyright (C) 19yy name of author
 323      Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
 324      This is free software, and you are welcome to redistribute it
 325      under certain conditions; type `show c' for details.
 326  
 327  The hypothetical commands `show w' and `show c' should show the appropriate
 328  parts of the General Public License.  Of course, the commands you use may
 329  be called something other than `show w' and `show c'; they could even be
 330  mouse-clicks or menu items--whatever suits your program.
 331  
 332  You should also get your employer (if you work as a programmer) or your
 333  school, if any, to sign a "copyright disclaimer" for the program, if
 334  necessary.  Here is a sample; alter the names:
 335  
 336    Yoyodyne, Inc., hereby disclaims all copyright interest in the program
 337    `Gnomovision' (which makes passes at compilers) written by James Hacker.

 341  
 342  This General Public License does not permit incorporating your program into
 343  proprietary programs.  If your program is a subroutine library, you may
 344  consider it more useful to permit linking proprietary applications with the
 345  library.  If this is what you want to do, use the GNU Library General
 346  Public License instead of this License.
