By contrast, the GNU General Public License is 31 intended to guarantee your freedom to share and change 32 free software - to make sure the software is free for all its users. 33 This General Public License applies to most of the Free Software 34 Foundation's software and to any other program whose authors commit 35 to using it. (Some other Free Software Foundation software is covered 36 by the GNU Library General Public License instead.) You can apply it 37 to your programs, too. 38 </para> 39 <para> When we speak of free software, we are referring to freedom, not price. 40 Our General Public Licenses are designed to make sure that you have the 41 freedom to distribute copies of free software (and charge for this 42 service if you wish), that you receive source code or can get it if you 43 want it, that you can change the software or use pieces of it in new free 44 programs; and that you know you can do these things. 45 </para> 46 <para> To protect your rights, we need to make restrictions that forbid anyone 47 to deny you these rights or to ask you to surrender the rights. These 48 restrictions translate to certain responsibilities for you if you distribute 49 copies of the software, or if you modify it. 50 </para> 51 <para> For example, if you distribute copies of such a program, whether gratis or 52 for a fee, you must give the recipients all the rights that you have. You 53 must make sure that they, too, receive or can get the source code. And you 54 must show them these terms so they know their rights. 55 </para> 56 <para> We protect your rights with two steps: 57 <orderedlist> 58 <listitem> 59 <para> copyright the software, and 60 </para> 61 </listitem> 62 <listitem> 63 <para> offer you this license which gives you legal permission to copy, 64 distribute and/or modify the software. 65 </para> 66 </listitem> 67 </orderedlist> 68 </para> 69 <para> Also, for each author's protection and ours, we want to make certain that 70 everyone understands that there is no warranty for this free software. If 71 the software is modified by someone else and passed on, we want its 72 recipients to know that what they have is not the original, so that any 73 problems introduced by others will not reflect on the original authors' 74 reputations. 75 </para> 76 <para> Finally, any free program is threatened constantly by software patents. 77 We wish to avoid the danger that redistributors of a free program will 78 individually obtain patent licenses, in effect making the program 79 proprietary. To prevent this, we have made it clear that any patent must be 80 licensed for everyone's free use or not licensed at all. 81 </para> 82 <para> The precise terms and conditions for copying, distribution and modification 83 follow. 84 </para> 85 </sect1> 86 <sect1> 87 <title>TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION</title> 88 <sect2> 89 <title>Section 0</title> 90 <para> This License applies to any program or other work which contains a notice 91 placed by the copyright holder saying it may be distributed under the terms 92 of this General Public License. The "Program", below, refers to any such 93 program or work, and a 94 <quote>work based on the Program 95 </quote> means either 96 the Program or any derivative work under copyright law: that is to say, a 97 work containing the Program or a portion of it, either verbatim or with 98 modifications and/or translated into another language. (Hereinafter, translation 99 is included without limitation in the term 100 <quote>modification 101 </quote>.) Each licensee is addressed as <quote>you</quote>. 102 </para> 103 <para> Activities other than copying, distribution and modification are not covered by 104 this License; they are outside its scope. The act of running the Program is not 105 restricted, and the output from the Program is covered only if its contents 106 constitute a work based on the Program (independent of having been made by running 107 the Program). Whether that is true depends on what the Program does. 108 </para> 109 </sect2> 110 <sect2 id="sect1"> 111 <title>Section 1</title> 112 <para> You may copy and distribute verbatim copies of the Program's source code as you 113 receive it, in any medium, provided that you conspicuously and appropriately 114 publish on each copy an appropriate copyright notice and disclaimer of warranty; 115 keep intact all the notices that refer to this License and to the absence of any 116 warranty; and give any other recipients of the Program a copy of this License 117 along with the Program. 118 </para> 119 <para> You may charge a fee for the physical act of transferring a copy, and you may at 120 your option offer warranty protection in exchange for a fee. 121 </para> 122 </sect2> 123 <sect2 id="sect2"> 124 <title>Section 2</title> 125 <para> You may modify your copy or copies of the Program or any portion of it, thus 126 forming a work based on the Program, and copy and distribute such modifications 127 or work under the terms of 128 <link linkend="sect1">Section 1 129 </link> above, provided 130 that you also meet all of these conditions: 131 <orderedlist> 132 <listitem> 133 <para> You must cause the modified files to carry prominent notices stating that 134 you changed the files and the date of any change. 135 </para> 136 </listitem> 137 <listitem> 138 <para> You must cause any work that you distribute or publish, that in whole or 139 in part contains or is derived from the Program or any part thereof, to be 140 licensed as a whole at no charge to all third parties under the terms of 141 this License. 142 </para> 143 </listitem> 144 <listitem> 145 <para> If the modified program normally reads commands interactively when run, you 146 must cause it, when started running for such interactive use in the most 147 ordinary way, to print or display an announcement including an appropriate 148 copyright notice and a notice that there is no warranty (or else, saying 149 that you provide a warranty) and that users may redistribute the program 150 under these conditions, and telling the user how to view a copy of this 151 License. 152 <note> 153 <title>Exception: 154 </title> 155 <para> If the Program itself is interactive but does not normally print such an 156 announcement, your work based on the Program is not required to print an 157 announcement.) 158 </para> 159 </note> 160 </para> 161 </listitem> 162 </orderedlist> 163 </para> 164 <para> These requirements apply to the modified work as a whole. If identifiable sections 165 of that work are not derived from the Program, and can be reasonably considered 166 independent and separate works in themselves, then this License, and its terms, 167 do not apply to those sections when you distribute them as separate works. But when 168 you distribute the same sections as part of a whole which is a work based on the 169 Program, the distribution of the whole must be on the terms of this License, whose 170 permissions for other licensees extend to the entire whole, and thus to each and 171 every part regardless of who wrote it. 172 </para> 173 <para> Thus, it is not the intent of this section to claim rights or contest your rights 174 to work written entirely by you; rather, the intent is to exercise the right to control 175 the distribution of derivative or collective works based on the Program. 176 </para> 177 <para> In addition, mere aggregation of another work not based on the Program with the Program 178 (or with a work based on the Program) on a volume of a storage or distribution medium 179 does not bring the other work under the scope of this License. 180 </para> 181 </sect2> 182 <sect2> 183 <title>Section 3 184 </title> 185 <para> You may copy and distribute the Program (or a work based on it, under 186 <link linkend="sect2">Section 2 187 </link> in object code or executable form under the terms of 188 <link linkend="sect1">Sections 1 189 </link> and 190 <link linkend="sect2">2 191 </link> above provided that you also do one of the following: 192 <orderedlist> 193 <listitem> 194 <para> Accompany it with the complete corresponding machine-readable source code, which 195 must be distributed under the terms of Sections 1 and 2 above on a medium 196 customarily used for software interchange; or, 197 </para> 198 </listitem> 199 <listitem> 200 <para> Accompany it with a written offer, valid for at least three years, to give any 201 third party, for a charge no more than your cost of physically performing source 202 distribution, a complete machine-readable copy of the corresponding source code, 203 to be distributed under the terms of Sections 1 and 2 above on a medium customarily 204 used for software interchange; or, 205 </para> 206 </listitem> 207 <listitem> 208 <para> Accompany it with the information you received as to the offer to distribute 209 corresponding source code. (This alternative is allowed only for noncommercial 210 distribution and only if you received the program in object code or executable form 211 with such an offer, in accord with Subsection b above.) 212 </para> 213 </listitem> 214 </orderedlist> 215 </para> 216 <para> The source code for a work means the preferred form of the work for making modifications 217 to it. For an executable work, complete source code means all the source code for all modules 218 it contains, plus any associated interface definition files, plus the scripts used to control 219 compilation and installation of the executable. However, as a special exception, the source 220 code distributed need not include anything that is normally distributed (in either source or 221 binary form) with the major components (compiler, kernel, and so on) of the operating system 222 on which the executable runs, unless that component itself accompanies the executable. 223 </para> 224 <para> If distribution of executable or object code is made by offering access to copy from a 225 designated place, then offering equivalent access to copy the source code from the same place 226 counts as distribution of the source code, even though third parties are not compelled to 227 copy the source along with the object code. 228 </para> 229 </sect2> 230 <sect2> 231 <title>Section 4 232 </title> 233 <para> You may not copy, modify, sublicense, or distribute the Program except as expressly provided 234 under this License. Any attempt otherwise to copy, modify, sublicense or distribute the 235 Program is void, and will automatically terminate your rights under this License. However, 236 parties who have received copies, or rights, from you under this License will not have their 237 licenses terminated so long as such parties remain in full compliance. 238 </para> 239 </sect2> 240 <sect2> 241 <title>Section 5 242 </title> 243 <para> You are not required to accept this License, since you have not signed it. However, nothing 244 else grants you permission to modify or distribute the Program or its derivative works. 245 These actions are prohibited by law if you do not accept this License. Therefore, by modifying 246 or distributing the Program (or any work based on the Program), you indicate your acceptance 247 of this License to do so, and all its terms and conditions for copying, distributing or 248 modifying the Program or works based on it. 249 </para> 250 </sect2> 251 <sect2> 252 <title>Section 6 253 </title> 254 <para> Each time you redistribute the Program (or any work based on the Program), the recipient 255 automatically receives a license from the original licensor to copy, distribute or modify 256 the Program subject to these terms and conditions. You may not impose any further restrictions 257 on the recipients' exercise of the rights granted herein. You are not responsible for enforcing 258 compliance by third parties to this License. 259 </para> 260 </sect2> 261 <sect2> 262 <title>Section 7 263 </title> 264 <para> If, as a consequence of a court judgment or allegation of patent infringement or for any other 265 reason (not limited to patent issues), conditions are imposed on you (whether by court order, 266 agreement or otherwise) that contradict the conditions of this License, they do not excuse you 267 from the conditions of this License. If you cannot distribute so as to satisfy simultaneously 268 your obligations under this License and any other pertinent obligations, then as a consequence 269 you may not distribute the Program at all. For example, if a patent license would not permit 270 royalty-free redistribution of the Program by all those who receive copies directly or 271 indirectly through you, then the only way you could satisfy both it and this License would be 272 to refrain entirely from distribution of the Program. 273 </para> 274 <para> If any portion of this section is held invalid or unenforceable under any particular circumstance, 275 the balance of the section is intended to apply and the section as a whole is intended to apply 276 in other circumstances. 277 </para> 278 <para> It is not the purpose of this section to induce you to infringe any patents or other property 279 right claims or to contest validity of any such claims; this section has the sole purpose of 280 protecting the integrity of the free software distribution system, which is implemented by public 281 license practices. Many people have made generous contributions to the wide range of software 282 distributed through that system in reliance on consistent application of that system; it is up 283 to the author/donor to decide if he or she is willing to distribute software through any other 284 system and a licensee cannot impose that choice. 285 </para> 286 <para> This section is intended to make thoroughly clear what is believed to be a consequence of the 287 rest of this License. 288 </para> 289 </sect2> 290 <sect2> 291 <title>Section 8 292 </title> 293 <para> If the distribution and/or use of the Program is restricted in certain countries either by patents 294 or by copyrighted interfaces, the original copyright holder who places the Program under this License 295 may add an explicit geographical distribution limitation excluding those countries, so that 296 distribution is permitted only in or among countries not thus excluded. In such case, this License 297 incorporates the limitation as if written in the body of this License. 298 </para> 299 </sect2> 300 <sect2> 301 <title>Section 9 302 </title> 303 <para> The Free Software Foundation may publish revised and/or new versions of the General Public License 304 from time to time. Such new versions will be similar in spirit to the present version, but may differ 305 in detail to address new problems or concerns. 306 </para> 307 <para> Each version is given a distinguishing version number. If the Program specifies a version number of 308 this License which applies to it and "any later version", you have the option of following the terms 309 and conditions either of that version or of any later version published by the Free Software 310 Foundation. If the Program does not specify a version number of this License, you may choose any 311 version ever published by the Free Software Foundation. 312 </para> 313 </sect2> 314 <sect2> 315 <title>Section 10 316 </title> 317 <para> If you wish to incorporate parts of the Program into other free programs whose distribution 318 conditions are different, write to the author to ask for permission. For software which is copyrighted 319 by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions 320 for this. Our decision will be guided by the two goals of preserving the free status of all 321 derivatives of our free software and of promoting the sharing and reuse of software generally. 322 </para> 323 </sect2> 324 <sect2> 325<title>NO WARRANTY Section 11 326 </title> 327 <para> BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT 328 PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR 329 OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, 330 INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR 331 PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE 332 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 333 </para> 334 </sect2> 335 <sect2> 336 <title>Section 12 337 </title> 338 <para> IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR 339 ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU 340 FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE 341 USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED 342 INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH 343 ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH 344 DAMAGES. 345 </para> 346 <para>END OF TERMS AND CONDITIONS 347 </para> 348 </sect2> 349 </sect1> 350 <sect1> 351 <title>How to Apply These Terms to Your New Programs 352 </title> 353 <para> 354 If you develop a new program, and you want it to be of the greatest 355 possible use to the public, the best way to achieve this is to make it 356 free software which everyone can redistribute and change under these terms. 357 </para> 358 <para> 359 To do so, attach the following notices to the program. It is safest 360 to attach them to the start of each source file to most effectively 361 convey the exclusion of warranty; and each file should have at least 362 the "copyright" line and a pointer to where the full notice is found. 363 </para> 364 <para> 365 <one line to give the program's name and a brief idea of what it does.> 366 Copyright (C) <year> <name of author> 367 </para> 368 <para> 369 This program is free software; you can redistribute it and/or modify 370 it under the terms of the GNU General Public License as published by 371 the Free Software Foundation; either version 2 of the License, or 372 (at your option) any later version. 373 </para> 374 <para> 375 This program is distributed in the hope that it will be useful, 376 but WITHOUT ANY WARRANTY; without even the implied warranty of 377 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the 378 GNU General Public License for more details. 379 </para> 380 <para> 381 You should have received a copy of the GNU General Public License 382 along with this program; if not, write to the Free Software 383 Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA 384 </para> 385 <para> 386 Also add information on how to contact you by electronic and paper mail. 387 </para> 388 <para> 389 If the program is interactive, make it output a short notice like this 390 when it starts in an interactive mode: 391 </para> 392 <para> 393 Gnomovision version 69, Copyright (C) year name of author 394 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. 395 This is free software, and you are welcome to redistribute it 396 under certain conditions; type `show c' for details. 397 </para> 398 <para> 399 The hypothetical commands `show w' and `show c' should show the appropriate 400 parts of the General Public License. Of course, the commands you use may 401 be called something other than `show w' and `show c'; they could even be 402 mouse-clicks or menu items--whatever suits your program. 403 </para> 404 <para> 405 You should also get your employer (if you work as a programmer) or your 406 school, if any, to sign a "copyright disclaimer" for the program, if 407 necessary. Here is a sample; alter the names: 408 </para> 409 <para> 410 Yoyodyne, Inc., hereby disclaims all copyright interest in the program 411 `Gnomovision' (which makes passes at compilers) written by James Hacker. 412 </para> 413 <para> 414 <signature of Ty Coon>, 1 April 1989 415 Ty Coon, President of Vice 416 </para> 417 <para> 418 This General Public License does not permit incorporating your program into 419 proprietary programs. If your program is a subroutine library, you may 420 consider it more useful to permit linking proprietary applications with the 421 library. If this is what you want to do, use the GNU Library General 422 Public License instead of this License. 423 </para> 424 </sect1> 425 </appendix> 426
