  24 @unnumberedsec Preamble
  25
  26   The license agreements of most software companies try to keep users
  27 at the mercy of those companies.  By contrast, our General Public
  28 License is intended to guarantee your freedom to share and change free
  29 software---to make sure the software is free for all its users.  The
  30 General Public License applies to the Free Software Foundation's
  31 software and to any other program whose authors commit to using it.
  32 You can use it for your programs, too.
  33
  34   When we speak of free software, we are referring to freedom, not
  35 price.  Specifically, the General Public License is designed to make
  36 sure that you have the freedom to give away or sell copies of free
  37 software, that you receive source code or can get it if you want it,
  38 that you can change the software or use pieces of it in new free
  39 programs; and that you know you can do these things.
  40
  41   To protect your rights, we need to make restrictions that forbid
  42 anyone to deny you these rights or to ask you to surrender the rights.
  43 These restrictions translate to certain responsibilities for you if you
  44 distribute copies of the software, or if you modify it.
  45
  46   For example, if you distribute copies of a such a program, whether
  47 gratis or for a fee, you must give the recipients all the rights that
  48 you have.  You must make sure that they, too, receive or can get the
  49 source code.  And you must tell them their 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   The precise terms and conditions for copying, distribution and
  63 modification follow.

  74 This License Agreement applies to any program or other work which
  75 contains a notice placed by the copyright holder saying it may be
  76 distributed under the terms of this General Public License.  The
  77 ``Program'', below, refers to any such program or work, and a ``work based
  78 on the Program'' means either the Program or any work containing the
  79 Program or a portion of it, either verbatim or with modifications.  Each
  80 licensee is addressed as ``you''.
  81
  82 @item
  83 You may copy and distribute verbatim copies of the Program's source
  84 code as you receive it, in any medium, provided that you conspicuously and
  85 appropriately publish on each copy an appropriate copyright notice and
  86 disclaimer of warranty; keep intact all the notices that refer to this
  87 General Public License and to the absence of any warranty; and give any
  88 other recipients of the Program a copy of this General Public License
  89 along with the Program.  You may charge a fee for the physical act of
  90 transferring a copy.
  91
  92 @item
  93 You may modify your copy or copies of the Program or any portion of
  94 it, and copy and distribute such modifications under the terms of Paragraph
  95 1 above, provided that you also do the following:
  96
  97 @itemize @bullet
  98 @item
  99 cause the modified files to carry prominent notices stating that
 100 you changed the files and the date of any change; and
 101
 102 @item
 103 cause the whole of any work that you distribute or publish, that
 104 in whole or in part contains the Program or any part thereof, either
 105 with or without modifications, to be licensed at no charge to all
 106 third parties under the terms of this General Public License (except
 107 that you may choose to grant warranty protection to some or all
 108 third parties, at your option).
 109
 110 @item
 111 If the modified program normally reads commands interactively when
 112 run, you must cause it, when started running for such interactive use
 113 in the simplest and most usual way, to print or display an
 114 announcement including an appropriate copyright notice and a notice
 115 that there is no warranty (or else, saying that you provide a
 116 warranty) and that users may redistribute the program under these
 117 conditions, and telling the user how to view a copy of this General
 118 Public License.
 119
 120 @item
 121 You may charge a fee for the physical act of transferring a
 122 copy, and you may at your option offer warranty protection in
 123 exchange for a fee.
 124 @end itemize
 125
 126 Mere aggregation of another independent work with the Program (or its
 127 derivative) on a volume of a storage or distribution medium does not bring
 128 the other work under the scope of these terms.
 129
 130 @item
 131 You may copy and distribute the Program (or a portion or derivative of
 132 it, under Paragraph 2) in object code or executable form under the terms of
 133 Paragraphs 1 and 2 above provided that you also do one of the following:
 134
 135 @itemize @bullet
 136 @item
 137 accompany it with the complete corresponding machine-readable
 138 source code, which must be distributed under the terms of
 139 Paragraphs 1 and 2 above; or,
 140
 141 @item
 142 accompany it with a written offer, valid for at least three
 143 years, to give any third party free (except for a nominal charge
 144 for the cost of distribution) a complete machine-readable copy of the
 145 corresponding source code, to be distributed under the terms of
 146 Paragraphs 1 and 2 above; or,
 147
 148 @item
 149 accompany it with the information you received as to where the
 150 corresponding source code may be obtained.  (This alternative is
 151 allowed only for noncommercial distribution and only if you
 152 received the program in object code or executable form alone.)
 153 @end itemize
 154
 155 Source code for a work means the preferred form of the work for making
 156 modifications to it.  For an executable file, complete source code means
 157 all the source code for all modules it contains; but, as a special
 158 exception, it need not include source code for modules which are standard
 159 libraries that accompany the operating system on which the executable
 160 file runs, or for standard header files or definitions files that
 161 accompany that operating system.
 162
 163 @item
 164 You may not copy, modify, sublicense, distribute or transfer the
 165 Program except as expressly provided under this General Public License.
 166 Any attempt otherwise to copy, modify, sublicense, distribute or transfer
 167 the Program is void, and will automatically terminate your rights to use
 168 the Program under this License.  However, parties who have received
 169 copies, or rights to use copies, from you under this General Public
 170 License will not have their licenses terminated so long as such parties
 171 remain in full compliance.
 172
 173 @item
 174 By copying, distributing or modifying the Program (or any work based
 175 on the Program) you indicate your acceptance of this license to do so,
 176 and all its terms and conditions.
 177
 178 @item
 179 Each time you redistribute the Program (or any work based on the
 180 Program), the recipient automatically receives a license from the original
 181 licensor to copy, distribute or modify the Program subject to these
 182 terms and conditions.  You may not impose any further restrictions on the
 183 recipients' exercise of the rights granted herein.
 184
 185 @item
 186 The Free Software Foundation may publish revised and/or new versions
 187 of the General Public License from time to time.  Such new versions will
 188 be similar in spirit to the present version, but may differ in detail to
 189 address new problems or concerns.
 190
 191 Each version is given a distinguishing version number.  If the Program
 192 specifies a version number of the license which applies to it and ``any
 193 later version'', you have the option of following the terms and conditions
 194 either of that version or of any later version published by the Free
 195 Software Foundation.  If the Program does not specify a version number of
 196 the license, you may choose any version ever published by the Free Software
 197 Foundation.
 198
 199 @item
 200 If you wish to incorporate parts of the Program into other free
 201 programs whose distribution conditions are different, write to the author
 202 to ask for permission.  For software which is copyrighted by the Free
 203 Software Foundation, write to the Free Software Foundation; we sometimes
 204 make exceptions for this.  Our decision will be guided by the two goals
 205 of preserving the free status of all derivatives of our free software and
 206 of promoting the sharing and reuse of software generally.

 219 PROVIDE THE PROGRAM ``AS IS'' WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
 220 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
 221 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
 222 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
 223 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
 224 REPAIR OR CORRECTION.
 225
 226 @item
 227 IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL
 228 ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
 229 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
 230 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES
 231 ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT
 232 LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES
 233 SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE
 234 WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN

 246 @unnumberedsec Applying These Terms to Your New Programs
 247
 248   If you develop a new program, and you want it to be of the greatest
 249 possible use to humanity, the best way to achieve this is to make it
 250 free software which everyone can redistribute and change under these
 251 terms.
 252
 253   To do so, attach the following notices to the program.  It is safest to
 254 attach them to the start of each source file to most effectively convey
 255 the exclusion of warranty; and each file should have at least the
 256 ``copyright'' line and a pointer to where the full notice is found.
 257
 258 @smallexample
 259 @var{one line to give the program's name and a brief idea of what it does.}
 260 Copyright (C) 19@var{yy}  @var{name of author}
 261
 262 This program is free software; you can redistribute it and/or modify
 263 it under the terms of the GNU General Public License as published by
 264 the Free Software Foundation; either version 1, or (at your option)
 265 any later version.
 266
 267 This program is distributed in the hope that it will be useful,
 268 but WITHOUT ANY WARRANTY; without even the implied warranty of
 269 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
 270 GNU General Public License for more details.
 271
 272 You should have received a copy of the GNU General Public License
 273 along with this program; if not, write to the Free Software
 274 Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
 275 @end smallexample
 276
 277 Also add information on how to contact you by electronic and paper mail.
 278
 279 If the program is interactive, make it output a short notice like this
 280 when it starts in an interactive mode:
 281
 282 @smallexample
 283 Gnomovision version 69, Copyright (C) 19@var{yy} @var{name of author}
 284 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
 285 This is free software, and you are welcome to redistribute it
 286 under certain conditions; type `show c' for details.
 287 @end smallexample
 288
 289 The hypothetical commands `show w' and `show c' should show the
 290 appropriate parts of the General Public License.  Of course, the
 291 commands you use may be called something other than `show w' and `show
 292 c'; they could even be mouse-clicks or menu items---whatever suits your
 293 program.
 294
 295 You should also get your employer (if you work as a programmer) or your
 296 school, if any, to sign a ``copyright disclaimer'' for the program, if
 297 necessary.  Here is a sample; alter the names:
 298
 299 @smallexample
