By contrast, the GNU 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. This 16 | General Public License applies to most of the Free Software 17 | Foundation's software and to any other program whose authors commit to 18 | using it. (Some other Free Software Foundation software is covered by 19 | the GNU Library General Public License instead.) You can apply it to 20 | your programs, too. 21 | 22 | When we speak of free software, we are referring to freedom, not 23 | price. Our General Public Licenses are designed to make sure that you 24 | have the freedom to distribute copies of free software (and charge for 25 | this service if you wish), that you receive source code or can get it 26 | if you want it, that you can change the software or use pieces of it 27 | in new free programs; and that you know you can do these things. 28 | 29 | To protect your rights, we need to make restrictions that forbid 30 | anyone to deny you these rights or to ask you to surrender the rights. 31 | These restrictions translate to certain responsibilities for you if you 32 | distribute copies of the software, or if you modify it. 33 | 34 | For example, if you distribute copies of such a program, whether 35 | gratis or for a fee, you must give the recipients all the rights that 36 | you have. You must make sure that they, too, receive or can get the 37 | source code. And you must show them these terms so they know their 38 | rights. 39 | 40 | We protect your rights with two steps: (1) copyright the software, and 41 | (2) offer you this license which gives you legal permission to copy, 42 | distribute and/or modify the software. 43 | 44 | Also, for each author's protection and ours, we want to make certain 45 | that everyone understands that there is no warranty for this free 46 | software. If the software is modified by someone else and passed on, we 47 | want its recipients to know that what they have is not the original, so 48 | that any problems introduced by others will not reflect on the original 49 | authors' reputations. 50 | 51 | Finally, any free program is threatened constantly by software 52 | patents. We wish to avoid the danger that redistributors of a free 53 | program will individually obtain patent licenses, in effect making the 54 | program proprietary. To prevent this, we have made it clear that any 55 | patent must be licensed for everyone's free use or not licensed at all. 56 | 57 | The precise terms and conditions for copying, distribution and 58 | modification follow. 59 | 60 | GNU GENERAL PUBLIC LICENSE 61 | TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 62 | 63 | 0. This License applies to any program or other work which contains 64 | a notice placed by the copyright holder saying it may be distributed 65 | under the terms of this General Public License. The "Program", below, 66 | refers to any such program or work, and a "work based on the Program" 67 | means either the Program or any derivative work under copyright law: 68 | that is to say, a work containing the Program or a portion of it, 69 | either verbatim or with modifications and/or translated into another 70 | language. (Hereinafter, translation is included without limitation in 71 | the term "modification".) Each licensee is addressed as "you". 72 | 73 | Activities other than copying, distribution and modification are not 74 | covered by this License; they are outside its scope. The act of 75 | running the Program is not restricted, and the output from the Program 76 | is covered only if its contents constitute a work based on the 77 | Program (independent of having been made by running the Program). 78 | Whether that is true depends on what the Program does. 79 | 80 | 1. You may copy and distribute verbatim copies of the Program's 81 | source code as you receive it, in any medium, provided that you 82 | conspicuously and appropriately publish on each copy an appropriate 83 | copyright notice and disclaimer of warranty; keep intact all the 84 | notices that refer to this License and to the absence of any warranty; 85 | and give any other recipients of the Program a copy of this License 86 | along with the Program. 87 | 88 | You may charge a fee for the physical act of transferring a copy, and 89 | you may at your option offer warranty protection in exchange for a fee. 90 | 91 | 2. You may modify your copy or copies of the Program or any portion 92 | of it, thus forming a work based on the Program, and copy and 93 | distribute such modifications or work under the terms of Section 1 94 | above, provided that you also meet all of these conditions: 95 | 96 | a) You must cause the modified files to carry prominent notices 97 | stating that you changed the files and the date of any change. 98 | 99 | b) You must cause any work that you distribute or publish, that in 100 | whole or in part contains or is derived from the Program or any 101 | part thereof, to be licensed as a whole at no charge to all third 102 | parties under the terms of this License. 103 | 104 | c) If the modified program normally reads commands interactively 105 | when run, you must cause it, when started running for such 106 | interactive use in the most ordinary way, to print or display an 107 | announcement including an appropriate copyright notice and a 108 | notice that there is no warranty (or else, saying that you provide 109 | a warranty) and that users may redistribute the program under 110 | these conditions, and telling the user how to view a copy of this 111 | License. (Exception: if the Program itself is interactive but 112 | does not normally print such an announcement, your work based on 113 | the Program is not required to print an announcement.) 114 | 115 | These requirements apply to the modified work as a whole. If 116 | identifiable sections of that work are not derived from the Program, 117 | and can be reasonably considered independent and separate works in 118 | themselves, then this License, and its terms, do not apply to those 119 | sections when you distribute them as separate works. But when you 120 | distribute the same sections as part of a whole which is a work based 121 | on the Program, the distribution of the whole must be on the terms of 122 | this License, whose permissions for other licensees extend to the 123 | entire whole, and thus to each and every part regardless of who wrote it. 124 | 125 | Thus, it is not the intent of this section to claim rights or contest 126 | your rights to work written entirely by you; rather, the intent is to 127 | exercise the right to control the distribution of derivative or 128 | collective works based on the Program. 129 | 130 | In addition, mere aggregation of another work not based on the Program 131 | with the Program (or with a work based on the Program) on a volume of 132 | a storage or distribution medium does not bring the other work under 133 | the scope of this License. 134 | 135 | 3. You may copy and distribute the Program (or a work based on it, 136 | under Section 2) in object code or executable form under the terms of 137 | Sections 1 and 2 above provided that you also do one of the following: 138 | 139 | a) Accompany it with the complete corresponding machine-readable 140 | source code, which must be distributed under the terms of Sections 141 | 1 and 2 above on a medium customarily used for software interchange; or, 142 | 143 | b) Accompany it with a written offer, valid for at least three 144 | years, to give any third party, for a charge no more than your 145 | cost of physically performing source distribution, a complete 146 | machine-readable copy of the corresponding source code, to be 147 | distributed under the terms of Sections 1 and 2 above on a medium 148 | customarily used for software interchange; or, 149 | 150 | c) Accompany it with the information you received as to the offer 151 | to distribute corresponding source code. (This alternative is 152 | allowed only for noncommercial distribution and only if you 153 | received the program in object code or executable form with such 154 | an offer, in accord with Subsection b above.) 155 | 156 | The source code for a work means the preferred form of the work for 157 | making modifications to it. For an executable work, complete source 158 | code means all the source code for all modules it contains, plus any 159 | associated interface definition files, plus the scripts used to 160 | control compilation and installation of the executable. However, as a 161 | special exception, the source code distributed need not include 162 | anything that is normally distributed (in either source or binary 163 | form) with the major components (compiler, kernel, and so on) of the 164 | operating system on which the executable runs, unless that component 165 | itself accompanies the executable. 166 | 167 | If distribution of executable or object code is made by offering 168 | access to copy from a designated place, then offering equivalent 169 | access to copy the source code from the same place counts as 170 | distribution of the source code, even though third parties are not 171 | compelled to copy the source along with the object code. 172 | 173 | 4. You may not copy, modify, sublicense, or distribute the Program 174 | except as expressly provided under this License. Any attempt 175 | otherwise to copy, modify, sublicense or distribute the Program is 176 | void, and will automatically terminate your rights under this License. 177 | However, parties who have received copies, or rights, from you under 178 | this License will not have their licenses terminated so long as such 179 | parties remain in full compliance. 180 | 181 | 5. You are not required to accept this License, since you have not 182 | signed it. However, nothing else grants you permission to modify or 183 | distribute the Program or its derivative works. These actions are 184 | prohibited by law if you do not accept this License. Therefore, by 185 | modifying or distributing the Program (or any work based on the 186 | Program), you indicate your acceptance of this License to do so, and 187 | all its terms and conditions for copying, distributing or modifying 188 | the Program or works based on it. 189 | 190 | 6. Each time you redistribute the Program (or any work based on the 191 | Program), the recipient automatically receives a license from the 192 | original licensor to copy, distribute or modify the Program subject to 193 | these terms and conditions. You may not impose any further 194 | restrictions on the recipients' exercise of the rights granted herein. 195 | You are not responsible for enforcing compliance by third parties to 196 | this License. 197 | 198 | 7. If, as a consequence of a court judgment or allegation of patent 199 | infringement or for any other reason (not limited to patent issues), 200 | conditions are imposed on you (whether by court order, agreement or 201 | otherwise) that contradict the conditions of this License, they do not 202 | excuse you from the conditions of this License. If you cannot 203 | distribute so as to satisfy simultaneously your obligations under this 204 | License and any other pertinent obligations, then as a consequence you 205 | may not distribute the Program at all. For example, if a patent 206 | license would not permit royalty-free redistribution of the Program by 207 | all those who receive copies directly or indirectly through you, then 208 | the only way you could satisfy both it and this License would be to 209 | refrain entirely from distribution of the Program. 210 | 211 | If any portion of this section is held invalid or unenforceable under 212 | any particular circumstance, the balance of the section is intended to 213 | apply and the section as a whole is intended to apply in other 214 | circumstances. 215 | 216 | It is not the purpose of this section to induce you to infringe any 217 | patents or other property right claims or to contest validity of any 218 | such claims; this section has the sole purpose of protecting the 219 | integrity of the free software distribution system, which is 220 | implemented by public license practices. Many people have made 221 | generous contributions to the wide range of software distributed 222 | through that system in reliance on consistent application of that 223 | system; it is up to the author/donor to decide if he or she is willing 224 | to distribute software through any other system and a licensee cannot 225 | impose that choice. 226 | 227 | This section is intended to make thoroughly clear what is believed to 228 | be a consequence of the rest of this License. 229 | 230 | 8. If the distribution and/or use of the Program is restricted in 231 | certain countries either by patents or by copyrighted interfaces, the 232 | original copyright holder who places the Program under this License 233 | may add an explicit geographical distribution limitation excluding 234 | those countries, so that distribution is permitted only in or among 235 | countries not thus excluded. In such case, this License incorporates 236 | the limitation as if written in the body of this License. 237 | 238 | 9. The Free Software Foundation may publish revised and/or new versions 239 | of the General Public License from time to time. Such new versions will 240 | be similar in spirit to the present version, but may differ in detail to 241 | address new problems or concerns. 242 | 243 | Each version is given a distinguishing version number. If the Program 244 | specifies a version number of this License which applies to it and "any 245 | later version", you have the option of following the terms and conditions 246 | either of that version or of any later version published by the Free 247 | Software Foundation. If the Program does not specify a version number of 248 | this License, you may choose any version ever published by the Free Software 249 | Foundation. 250 | 251 | 10. If you wish to incorporate parts of the Program into other free 252 | programs whose distribution conditions are different, write to the author 253 | to ask for permission. For software which is copyrighted by the Free 254 | Software Foundation, write to the Free Software Foundation; we sometimes 255 | make exceptions for this. Our decision will be guided by the two goals 256 | of preserving the free status of all derivatives of our free software and 257 | of promoting the sharing and reuse of software generally. 258 | 259 | NO WARRANTY 260 | 261 | 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY 262 | FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN 263 | OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES 264 | PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED 265 | OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF 266 | MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS 267 | TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE 268 | PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, 269 | REPAIR OR CORRECTION. 270 | 271 | 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 272 | WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR 273 | REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, 274 | INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING 275 | OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED 276 | TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY 277 | YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER 278 | PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE 279 | POSSIBILITY OF SUCH DAMAGES. 280 | 281 | END OF TERMS AND CONDITIONS 282 | 283 | Appendix: How to Apply These Terms to Your New Programs 284 | 285 | If you develop a new program, and you want it to be of the greatest 286 | possible use to the public, the best way to achieve this is to make it 287 | free software which everyone can redistribute and change under these terms. 288 | 289 | To do so, attach the following notices to the program. It is safest 290 | to attach them to the start of each source file to most effectively 291 | convey the exclusion of warranty; and each file should have at least 292 | the "copyright" line and a pointer to where the full notice is found. 293 | 294 | 295 | Copyright (C) 19yy 296 | 297 | This program is free software; you can redistribute it and/or modify 298 | it under the terms of the GNU General Public License as published by 299 | the Free Software Foundation; either version 2 of the License, or 300 | (at your option) any later version. 301 | 302 | This program is distributed in the hope that it will be useful, 303 | but WITHOUT ANY WARRANTY; without even the implied warranty of 304 | MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the 305 | GNU General Public License for more details. 306 | 307 | You should have received a copy of the GNU General Public License 308 | along with this program; if not, write to the Free Software 309 | Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111 USA 310 | 311 | Also add information on how to contact you by electronic and paper mail. 312 | 313 | If the program is interactive, make it output a short notice like this 314 | when it starts in an interactive mode: 315 | 316 | Gnomovision version 69, Copyright (C) 19yy name of author 317 | Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. 318 | This is free software, and you are welcome to redistribute it 319 | under certain conditions; type `show c' for details. 320 | 321 | The hypothetical commands `show w' and `show c' should show the appropriate 322 | parts of the General Public License. Of course, the commands you use may 323 | be called something other than `show w' and `show c'; they could even be 324 | mouse-clicks or menu items--whatever suits your program. 325 | 326 | You should also get your employer (if you work as a programmer) or your 327 | school, if any, to sign a "copyright disclaimer" for the program, if 328 | necessary. Here is a sample; alter the names: 329 | 330 | Yoyodyne, Inc., hereby disclaims all copyright interest in the program 331 | `Gnomovision' (which makes passes at compilers) written by James Hacker. 332 | 333 | , 1 April 1989 334 | Ty Coon, President of Vice 335 | 336 | This General Public License does not permit incorporating your program into 337 | proprietary programs. If your program is a subroutine library, you may 338 | consider it more useful to permit linking proprietary applications with the 339 | library. If this is what you want to do, use the GNU Library General 340 | Public License instead of this License. 341 | --------------------------------------------------------------------------------
