   3  
   4   Copyright (C) 1989, 1991 Free Software Foundation, Inc.
   5                            675 Mass Ave, Cambridge, MA 02139, 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 Library 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  Thus, it is not the intent of this section to claim rights or contest
 124  your rights to work written entirely by you; rather, the intent is to
 125  exercise the right to control the distribution of derivative or
 126  collective works based on the Program.
 127  
 128  In addition, mere aggregation of another work not based on the Program
 129  with the Program (or with a work based on the Program) on a volume of
 130  a storage or distribution medium does not bring the other work under
 131  the scope of this License.
 132  
 133    3. You may copy and distribute the Program (or a work based on it,
 134  under Section 2) in object code or executable form under the terms of
 135  Sections 1 and 2 above provided that you also do one of the following:
 136  
 137      a) Accompany it with the complete corresponding machine-readable
 138      source code, which must be distributed under the terms of Sections
 139      1 and 2 above on a medium customarily used for software interchange; or,
 140  
 141      b) Accompany it with a written offer, valid for at least three
 142      years, to give any third party, for a charge no more than your
 143      cost of physically performing source distribution, a complete
 144      machine-readable copy of the corresponding source code, to be
 145      distributed under the terms of Sections 1 and 2 above on a medium
 146      customarily used for software interchange; or,
 147  
 148      c) Accompany it with the information you received as to the offer
 149      to distribute corresponding source code.  (This alternative is
 150      allowed only for noncommercial distribution and only if you
 151      received the program in object code or executable form with such
 152      an offer, in accord with Subsection b above.)
 153  
 154  The source code for a work means the preferred form of the work for
 155  making modifications to it.  For an executable work, complete source
 156  code means all the source code for all modules it contains, plus any
 157  associated interface definition files, plus the scripts used to
 158  control compilation and installation of the executable.  However, as a
 159  special exception, the source code distributed need not include
 160  anything that is normally distributed (in either source or binary
 161  form) with the major components (compiler, kernel, and so on) of the
 162  operating system on which the executable runs, unless that component
 163  itself accompanies the executable.
 164  
 165  If distribution of executable or object code is made by offering
 166  access to copy from a designated place, then offering equivalent
 167  access to copy the source code from the same place counts as
 168  distribution of the source code, even though third parties are not
 169  compelled to copy the source along with the object code.
 170  
 171    4. You may not copy, modify, sublicense, or distribute the Program
 172  except as expressly provided under this License.  Any attempt
 173  otherwise to copy, modify, sublicense or distribute the Program is
 174  void, and will automatically terminate your rights under this License.
 175  However, parties who have received copies, or rights, from you under
 176  this License will not have their licenses terminated so long as such
 177  parties remain in full compliance.
 178  
 179    5. You are not required to accept this License, since you have not
 180  signed it.  However, nothing else grants you permission to modify or
 181  distribute the Program or its derivative works.  These actions are
 182  prohibited by law if you do not accept this License.  Therefore, by
 183  modifying or distributing the Program (or any work based on the
 184  Program), you indicate your acceptance of this License to do so, and
 185  all its terms and conditions for copying, distributing or modifying
 186  the Program or works based on it.
 187  
 188    6. Each time you redistribute the Program (or any work based on the
 189  Program), the recipient automatically receives a license from the
 190  original licensor to copy, distribute or modify the Program subject to
 191  these terms and conditions.  You may not impose any further
 192  restrictions on the recipients' exercise of the rights granted herein.
 193  You are not responsible for enforcing compliance by third parties to
 194  this License.
 195  
 196    7. If, as a consequence of a court judgment or allegation of patent
 197  infringement or for any other reason (not limited to patent issues),
 198  conditions are imposed on you (whether by court order, agreement or
 199  otherwise) that contradict the conditions of this License, they do not
 200  excuse you from the conditions of this License.  If you cannot
 201  distribute so as to satisfy simultaneously your obligations under this
 202  License and any other pertinent obligations, then as a consequence you
 203  may not distribute the Program at all.  For example, if a patent
 204  license would not permit royalty-free redistribution of the Program by
 205  all those who receive copies directly or indirectly through you, then
 206  the only way you could satisfy both it and this License would be to
 207  refrain entirely from distribution of the Program.
 208  
 209  If any portion of this section is held invalid or unenforceable under
 210  any particular circumstance, the balance of the section is intended to
 211  apply and the section as a whole is intended to apply in other
 212  circumstances.
 213  
 214  It is not the purpose of this section to induce you to infringe any
 215  patents or other property right claims or to contest validity of any
 216  such claims; this section has the sole purpose of protecting the
 217  integrity of the free software distribution system, which is
 218  implemented by public license practices.  Many people have made
 219  generous contributions to the wide range of software distributed
 220  through that system in reliance on consistent application of that
 221  system; it is up to the author/donor to decide if he or she is willing
 222  to distribute software through any other system and a licensee cannot
 223  impose that choice.
 224  
 225  This section is intended to make thoroughly clear what is believed to
 226  be a consequence of the rest of this License.
 227  
 228    8. If the distribution and/or use of the Program is restricted in
 229  certain countries either by patents or by copyrighted interfaces, the
 230  original copyright holder who places the Program under this License
 231  may add an explicit geographical distribution limitation excluding
 232  those countries, so that distribution is permitted only in or among
 233  countries not thus excluded.  In such case, this License incorporates
 234  the limitation as if written in the body of this License.
 235  
 236    9. The Free Software Foundation may publish revised and/or new versions
 237  of the General Public License from time to time.  Such new versions will
 238  be similar in spirit to the present version, but may differ in detail to
 239  address new problems or concerns.
 240  
 241  Each version is given a distinguishing version number.  If the Program
 242  specifies a version number of this License which applies to it and "any
 243  later version", you have the option of following the terms and conditions
 244  either of that version or of any later version published by the Free
 245  Software Foundation.  If the Program does not specify a version number of
 246  this License, you may choose any version ever published by the Free Software
 247  Foundation.
 248  
 249    10. If you wish to incorporate parts of the Program into other free
 250  programs whose distribution conditions are different, write to the author
 251  to ask for permission.  For software which is copyrighted by the Free
 252  Software Foundation, write to the Free Software Foundation; we sometimes
 253  make exceptions for this.  Our decision will be guided by the two goals
 254  of preserving the free status of all derivatives of our free software and
 255  of promoting the sharing and reuse of software generally.
 256  
 257                  NO WARRANTY
 258  
 259    11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
 260  FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
 261  OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
 262  PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
 263  OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
 264  MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
 265  TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
 266  PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
 267  REPAIR OR CORRECTION.
 268  
 269    12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
 270  WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
 271  REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
 272  INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
 273  OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
 274  TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
 275  YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
 276  PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
 277  POSSIBILITY OF SUCH DAMAGES.
