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

  11
  12   The license agreements of most software companies try to keep users
  13 at the mercy of those companies.  By contrast, our General Public
  14 License is intended to guarantee your freedom to share and change free
  15 software--to make sure the software is free for all its users.  The
  16 General Public License applies to the Free Software Foundation's
  17 software and to any other program whose authors commit to using it.
  18 You can use it for your programs, too.
  19
  20   When we speak of free software, we are referring to freedom, not
  21 price.  Specifically, the General Public License is designed to make
  22 sure that you have the freedom to give away or sell copies of free
  23 software, that you receive source code or can get it if you want it,
  24 that you can change the software or use pieces of it in new free
  25 programs; and that you know you can do these things.
  26
  27   To protect your rights, we need to make restrictions that forbid
  28 anyone to deny you these rights or to ask you to surrender the rights.
  29 These restrictions translate to certain responsibilities for you if you
  30 distribute copies of the software, or if you modify it.
  31
  32   For example, if you distribute copies of a such a program, whether
  33 gratis or for a fee, you must give the recipients all the rights that
  34 you have.  You must make sure that they, too, receive or can get the
  35 source code.  And you must tell them their rights.
  36
  37   We protect your rights with two steps: (1) copyright the software, and
  38 (2) offer you this license which gives you legal permission to copy,
  39 distribute and/or modify the software.
  40
  41   Also, for each author's protection and ours, we want to make certain
  42 that everyone understands that there is no warranty for this free
  43 software.  If the software is modified by someone else and passed on, we
  44 want its recipients to know that what they have is not the original, so
  45 that any problems introduced by others will not reflect on the original
  46 authors' reputations.
  47
  48   The precise terms and conditions for copying, distribution and
  49 modification follow.

  51                     GNU GENERAL PUBLIC LICENSE
  52    TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
  53
  54   0. This License Agreement applies to any program or other work which
  55 contains a notice placed by the copyright holder saying it may be
  56 distributed under the terms of this General Public License.  The
  57 "Program", below, refers to any such program or work, and a "work based
  58 on the Program" means either the Program or any work containing the
  59 Program or a portion of it, either verbatim or with modifications.  Each
  60 licensee is addressed as "you".
  61
  62   1. You may copy and distribute verbatim copies of the Program's source
  63 code as you receive it, in any medium, provided that you conspicuously and
  64 appropriately publish on each copy an appropriate copyright notice and
  65 disclaimer of warranty; keep intact all the notices that refer to this
  66 General Public License and to the absence of any warranty; and give any
  67 other recipients of the Program a copy of this General Public License
  68 along with the Program.  You may charge a fee for the physical act of
  69 transferring a copy.
  70
  71   2. You may modify your copy or copies of the Program or any portion of
  72 it, and copy and distribute such modifications under the terms of Paragraph
  73 1 above, provided that you also do the following:
  74
  75     a) cause the modified files to carry prominent notices stating that
  76     you changed the files and the date of any change; and
  77
  78     b) cause the whole of any work that you distribute or publish, that
  79     in whole or in part contains the Program or any part thereof, either
  80     with or without modifications, to be licensed at no charge to all
  81     third parties under the terms of this General Public License (except
  82     that you may choose to grant warranty protection to some or all
  83     third parties, at your option).
  84
  85     c) If the modified program normally reads commands interactively when
  86     run, you must cause it, when started running for such interactive use
  87     in the simplest and most usual way, to print or display an
  88     announcement including an appropriate copyright notice and a notice
  89     that there is no warranty (or else, saying that you provide a
  90     warranty) and that users may redistribute the program under these
  91     conditions, and telling the user how to view a copy of this General
  92     Public License.
  93
  94     d) You may charge a fee for the physical act of transferring a
  95     copy, and you may at your option offer warranty protection in
  96     exchange for a fee.
  97
  98 Mere aggregation of another independent work with the Program (or its
  99 derivative) on a volume of a storage or distribution medium does not bring
 100 the other work under the scope of these terms.
 101 \f
 102   3. You may copy and distribute the Program (or a portion or derivative of
 103 it, under Paragraph 2) in object code or executable form under the terms of
 104 Paragraphs 1 and 2 above provided that you also do one of the following:
 105
 106     a) accompany it with the complete corresponding machine-readable
 107     source code, which must be distributed under the terms of
 108     Paragraphs 1 and 2 above; or,
 109
 110     b) accompany it with a written offer, valid for at least three
 111     years, to give any third party free (except for a nominal charge
 112     for the cost of distribution) a complete machine-readable copy of the
 113     corresponding source code, to be distributed under the terms of
 114     Paragraphs 1 and 2 above; or,
 115
 116     c) accompany it with the information you received as to where the
 117     corresponding source code may be obtained.  (This alternative is
 118     allowed only for noncommercial distribution and only if you
 119     received the program in object code or executable form alone.)
 120
 121 Source code for a work means the preferred form of the work for making
 122 modifications to it.  For an executable file, complete source code means
 123 all the source code for all modules it contains; but, as a special
 124 exception, it need not include source code for modules which are standard
 125 libraries that accompany the operating system on which the executable
 126 file runs, or for standard header files or definitions files that
 127 accompany that operating system.
 128
 129   4. You may not copy, modify, sublicense, distribute or transfer the
 130 Program except as expressly provided under this General Public License.
 131 Any attempt otherwise to copy, modify, sublicense, distribute or transfer
 132 the Program is void, and will automatically terminate your rights to use
 133 the Program under this License.  However, parties who have received
 134 copies, or rights to use copies, from you under this General Public
 135 License will not have their licenses terminated so long as such parties
 136 remain in full compliance.
 137
 138   5. By copying, distributing or modifying the Program (or any work based
 139 on the Program) you indicate your acceptance of this license to do so,
 140 and all its terms and conditions.
 141
 142   6. Each time you redistribute the Program (or any work based on the
 143 Program), the recipient automatically receives a license from the original
 144 licensor to copy, distribute or modify the Program subject to these
 145 terms and conditions.  You may not impose any further restrictions on the
 146 recipients' exercise of the rights granted herein.
 147 \f
 148   7. The Free Software Foundation may publish revised and/or new versions
 149 of the General Public License from time to time.  Such new versions will
 150 be similar in spirit to the present version, but may differ in detail to
 151 address new problems or concerns.
 152
 153 Each version is given a distinguishing version number.  If the Program
 154 specifies a version number of the license which applies to it and "any
 155 later version", you have the option of following the terms and conditions
 156 either of that version or of any later version published by the Free
 157 Software Foundation.  If the Program does not specify a version number of
 158 the license, you may choose any version ever published by the Free Software
 159 Foundation.
 160
 161   8. If you wish to incorporate parts of the Program into other free
 162 programs whose distribution conditions are different, write to the author
 163 to ask for permission.  For software which is copyrighted by the Free
 164 Software Foundation, write to the Free Software Foundation; we sometimes
 165 make exceptions for this.  Our decision will be guided by the two goals
 166 of preserving the free status of all derivatives of our free software and
 167 of promoting the sharing and reuse of software generally.
 168
 169                             NO WARRANTY
 170
 171   9. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
 172 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
 173 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
 174 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
 175 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
 176 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
 177 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
 178 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
 179 REPAIR OR CORRECTION.
 180
 181   10. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
 182 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
 183 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
 184 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
 185 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
 186 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
 187 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
 188 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
 189 POSSIBILITY OF SUCH DAMAGES.
 190
 191                      END OF TERMS AND CONDITIONS
 192 \f
 193         Appendix: How to Apply These Terms to Your New Programs
 194
 195   If you develop a new program, and you want it to be of the greatest
 196 possible use to humanity, the best way to achieve this is to make it
 197 free software which everyone can redistribute and change under these
 198 terms.
 199
 200   To do so, attach the following notices to the program.  It is safest to
 201 attach them to the start of each source file to most effectively convey
 202 the exclusion of warranty; and each file should have at least the
 203 "copyright" line and a pointer to where the full notice is found.
 204
 205     <one line to give the program's name and a brief idea of what it does.>
 206     Copyright (C) 19yy  <name of author>
 207
 208     This program is free software; you can redistribute it and/or modify
 209     it under the terms of the GNU General Public License as published by
 210     the Free Software Foundation; either version 1, or (at your option)
 211     any later version.
 212
 213     This program is distributed in the hope that it will be useful,
 214     but WITHOUT ANY WARRANTY; without even the implied warranty of
 215     MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
 216     GNU General Public License for more details.
 217
 218     You should have received a copy of the GNU General Public License
 219     along with this program; if not, write to the Free Software
 220     Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
 221
 222 Also add information on how to contact you by electronic and paper mail.
 223
 224 If the program is interactive, make it output a short notice like this
 225 when it starts in an interactive mode:
 226
 227     Gnomovision version 69, Copyright (C) 19xx name of author
 228     Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
 229     This is free software, and you are welcome to redistribute it
 230     under certain conditions; type `show c' for details.
 231
 232 The hypothetical commands `show w' and `show c' should show the
 233 appropriate parts of the General Public License.  Of course, the
 234 commands you use may be called something other than `show w' and `show
 235 c'; they could even be mouse-clicks or menu items--whatever suits your
 236 program.
 237
 238 You should also get your employer (if you work as a programmer) or your
 239 school, if any, to sign a "copyright disclaimer" for the program, if
 240 necessary.  Here a sample; alter the names:
 241
 242   Yoyodyne, Inc., hereby disclaims all copyright interest in the
 243   program `Gnomovision' (a program to direct compilers to make passes
 244   at assemblers) written by James Hacker.

 249 That's all there is to it!
