By contrast, the GNU General Public 51 License is intended to guarantee your freedom to share and change free 52 software--to make sure the software is free for all its users. This 53 General Public License applies to most of the Free Software 54 Foundation's software and to any other program whose authors commit to 55 using it. (Some other Free Software Foundation software is covered by 56 the GNU Lesser General Public License instead.) You can apply it to 57 your programs, too. 58 59 When we speak of free software, we are referring to freedom, not 60 price. Our General Public Licenses are designed to make sure that you 61 have the freedom to distribute copies of free software (and charge for 62 this service if you wish), that you receive source code or can get it 63 if you want it, that you can change the software or use pieces of it 64 in new free programs; and that you know you can do these things. 65 66 To protect your rights, we need to make restrictions that forbid 67 anyone to deny you these rights or to ask you to surrender the rights. 68 These restrictions translate to certain responsibilities for you if you 69 distribute copies of the software, or if you modify it. 70 71 For example, if you distribute copies of such a program, whether 72 gratis or for a fee, you must give the recipients all the rights that 73 you have. You must make sure that they, too, receive or can get the 74 source code. And you must show them these terms so they know their 75 rights. 76 77 We protect your rights with two steps: (1) copyright the software, and 78 (2) offer you this license which gives you legal permission to copy, 79 distribute and/or modify the software. 80 81 Also, for each author's protection and ours, we want to make certain 82 that everyone understands that there is no warranty for this free 83 software. If the software is modified by someone else and passed on, we 84 want its recipients to know that what they have is not the original, so 85 that any problems introduced by others will not reflect on the original 86 authors' reputations. 87 88 Finally, any free program is threatened constantly by software 89 patents. We wish to avoid the danger that redistributors of a free 90 program will individually obtain patent licenses, in effect making the 91 program proprietary. To prevent this, we have made it clear that any 92 patent must be licensed for everyone's free use or not licensed at all. 93 94 The precise terms and conditions for copying, distribution and 95 modification follow. 96 97 GNU GENERAL PUBLIC LICENSE 98 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 99 100 0. This License applies to any program or other work which contains 101 a notice placed by the copyright holder saying it may be distributed 102 under the terms of this General Public License. The "Program", below, 103 refers to any such program or work, and a "work based on the Program" 104 means either the Program or any derivative work under copyright law: 105 that is to say, a work containing the Program or a portion of it, 106 either verbatim or with modifications and/or translated into another 107 language. (Hereinafter, translation is included without limitation in 108 the term "modification".) Each licensee is addressed as "you". 109 110 Activities other than copying, distribution and modification are not 111 covered by this License; they are outside its scope. The act of 112 running the Program is not restricted, and the output from the Program 113 is covered only if its contents constitute a work based on the 114 Program (independent of having been made by running the Program). 115 Whether that is true depends on what the Program does. 116 117 1. You may copy and distribute verbatim copies of the Program's 118 source code as you receive it, in any medium, provided that you 119 conspicuously and appropriately publish on each copy an appropriate 120 copyright notice and disclaimer of warranty; keep intact all the 121 notices that refer to this License and to the absence of any warranty; 122 and give any other recipients of the Program a copy of this License 123 along with the Program. 124 125 You may charge a fee for the physical act of transferring a copy, and 126 you may at your option offer warranty protection in exchange for a fee. 127 128 2. You may modify your copy or copies of the Program or any portion 129 of it, thus forming a work based on the Program, and copy and 130 distribute such modifications or work under the terms of Section 1 131 above, provided that you also meet all of these conditions: 132 133 a) You must cause the modified files to carry prominent notices 134 stating that you changed the files and the date of any change. 135 136 b) You must cause any work that you distribute or publish, that in 137 whole or in part contains or is derived from the Program or any 138 part thereof, to be licensed as a whole at no charge to all third 139 parties under the terms of this License. 140 141 c) If the modified program normally reads commands interactively 142 when run, you must cause it, when started running for such 143 interactive use in the most ordinary way, to print or display an 144 announcement including an appropriate copyright notice and a 145 notice that there is no warranty (or else, saying that you provide 146 a warranty) and that users may redistribute the program under 147 these conditions, and telling the user how to view a copy of this 148 License. (Exception: if the Program itself is interactive but 149 does not normally print such an announcement, your work based on 150 the Program is not required to print an announcement.) 151 152 These requirements apply to the modified work as a whole. If 153 identifiable sections of that work are not derived from the Program, 154 and can be reasonably considered independent and separate works in 155 themselves, then this License, and its terms, do not apply to those 156 sections when you distribute them as separate works. But when you 157 distribute the same sections as part of a whole which is a work based 158 on the Program, the distribution of the whole must be on the terms of 159 this License, whose permissions for other licensees extend to the 160 entire whole, and thus to each and every part regardless of who wrote it. 161 162 Thus, it is not the intent of this section to claim rights or contest 163 your rights to work written entirely by you; rather, the intent is to 164 exercise the right to control the distribution of derivative or 165 collective works based on the Program. 166 167 In addition, mere aggregation of another work not based on the Program 168 with the Program (or with a work based on the Program) on a volume of 169 a storage or distribution medium does not bring the other work under 170 the scope of this License. 171 172 3. You may copy and distribute the Program (or a work based on it, 173 under Section 2) in object code or executable form under the terms of 174 Sections 1 and 2 above provided that you also do one of the following: 175 176 a) Accompany it with the complete corresponding machine-readable 177 source code, which must be distributed under the terms of Sections 178 1 and 2 above on a medium customarily used for software interchange; or, 179 180 b) Accompany it with a written offer, valid for at least three 181 years, to give any third party, for a charge no more than your 182 cost of physically performing source distribution, a complete 183 machine-readable copy of the corresponding source code, to be 184 distributed under the terms of Sections 1 and 2 above on a medium 185 customarily used for software interchange; or, 186 187 c) Accompany it with the information you received as to the offer 188 to distribute corresponding source code. (This alternative is 189 allowed only for noncommercial distribution and only if you 190 received the program in object code or executable form with such 191 an offer, in accord with Subsection b above.) 192 193 The source code for a work means the preferred form of the work for 194 making modifications to it. For an executable work, complete source 195 code means all the source code for all modules it contains, plus any 196 associated interface definition files, plus the scripts used to 197 control compilation and installation of the executable. However, as a 198 special exception, the source code distributed need not include 199 anything that is normally distributed (in either source or binary 200 form) with the major components (compiler, kernel, and so on) of the 201 operating system on which the executable runs, unless that component 202 itself accompanies the executable. 203 204 If distribution of executable or object code is made by offering 205 access to copy from a designated place, then offering equivalent 206 access to copy the source code from the same place counts as 207 distribution of the source code, even though third parties are not 208 compelled to copy the source along with the object code. 209 210 4. You may not copy, modify, sublicense, or distribute the Program 211 except as expressly provided under this License. Any attempt 212 otherwise to copy, modify, sublicense or distribute the Program is 213 void, and will automatically terminate your rights under this License. 214 However, parties who have received copies, or rights, from you under 215 this License will not have their licenses terminated so long as such 216 parties remain in full compliance. 217 218 5. You are not required to accept this License, since you have not 219 signed it. However, nothing else grants you permission to modify or 220 distribute the Program or its derivative works. These actions are 221 prohibited by law if you do not accept this License. Therefore, by 222 modifying or distributing the Program (or any work based on the 223 Program), you indicate your acceptance of this License to do so, and 224 all its terms and conditions for copying, distributing or modifying 225 the Program or works based on it. 226 227 6. Each time you redistribute the Program (or any work based on the 228 Program), the recipient automatically receives a license from the 229 original licensor to copy, distribute or modify the Program subject to 230 these terms and conditions. You may not impose any further 231 restrictions on the recipients' exercise of the rights granted herein. 232 You are not responsible for enforcing compliance by third parties to 233 this License. 234 235 7. If, as a consequence of a court judgment or allegation of patent 236 infringement or for any other reason (not limited to patent issues), 237 conditions are imposed on you (whether by court order, agreement or 238 otherwise) that contradict the conditions of this License, they do not 239 excuse you from the conditions of this License. If you cannot 240 distribute so as to satisfy simultaneously your obligations under this 241 License and any other pertinent obligations, then as a consequence you 242 may not distribute the Program at all. For example, if a patent 243 license would not permit royalty-free redistribution of the Program by 244 all those who receive copies directly or indirectly through you, then 245 the only way you could satisfy both it and this License would be to 246 refrain entirely from distribution of the Program. 247 248 If any portion of this section is held invalid or unenforceable under 249 any particular circumstance, the balance of the section is intended to 250 apply and the section as a whole is intended to apply in other 251 circumstances. 252 253 It is not the purpose of this section to induce you to infringe any 254 patents or other property right claims or to contest validity of any 255 such claims; this section has the sole purpose of protecting the 256 integrity of the free software distribution system, which is 257 implemented by public license practices. Many people have made 258 generous contributions to the wide range of software distributed 259 through that system in reliance on consistent application of that 260 system; it is up to the author/donor to decide if he or she is willing 261 to distribute software through any other system and a licensee cannot 262 impose that choice. 263 264 This section is intended to make thoroughly clear what is believed to 265 be a consequence of the rest of this License. 266 267 8. If the distribution and/or use of the Program is restricted in 268 certain countries either by patents or by copyrighted interfaces, the 269 original copyright holder who places the Program under this License 270 may add an explicit geographical distribution limitation excluding 271 those countries, so that distribution is permitted only in or among 272 countries not thus excluded. In such case, this License incorporates 273 the limitation as if written in the body of this License. 274 275 9. The Free Software Foundation may publish revised and/or new versions 276 of the General Public License from time to time. Such new versions will 277 be similar in spirit to the present version, but may differ in detail to 278 address new problems or concerns. 279 280 Each version is given a distinguishing version number. If the Program 281 specifies a version number of this License which applies to it and "any 282 later version", you have the option of following the terms and conditions 283 either of that version or of any later version published by the Free 284 Software Foundation. If the Program does not specify a version number of 285 this License, you may choose any version ever published by the Free Software 286 Foundation. 287 288 10. If you wish to incorporate parts of the Program into other free 289 programs whose distribution conditions are different, write to the author 290 to ask for permission. For software which is copyrighted by the Free 291 Software Foundation, write to the Free Software Foundation; we sometimes 292 make exceptions for this. Our decision will be guided by the two goals 293 of preserving the free status of all derivatives of our free software and 294 of promoting the sharing and reuse of software generally. 295 296 NO WARRANTY 297 298 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY 299 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN 300 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES 301 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED 302 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF 303 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS 304 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE 305 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, 306 REPAIR OR CORRECTION. 307 308 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 309 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR 310 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, 311 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING 312 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED 313 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY 314 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER 315 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE 316 POSSIBILITY OF SUCH DAMAGES. 317 318 END OF TERMS AND CONDITIONS 319 320 How to Apply These Terms to Your New Programs 321 322 If you develop a new program, and you want it to be of the greatest 323 possible use to the public, the best way to achieve this is to make it 324 free software which everyone can redistribute and change under these terms. 325 326 To do so, attach the following notices to the program. It is safest 327 to attach them to the start of each source file to most effectively 328 convey the exclusion of warranty; and each file should have at least 329 the "copyright" line and a pointer to where the full notice is found. 330 331 <one line to give the program's name and a brief idea of what it does.> 332 Copyright (C) <year> <name of author> 333 334 This program is free software; you can redistribute it and/or modify 335 it under the terms of the GNU General Public License as published by 336 the Free Software Foundation; either version 2 of the License, or 337 (at your option) any later version. 338 339 This program is distributed in the hope that it will be useful, 340 but WITHOUT ANY WARRANTY; without even the implied warranty of 341 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the 342 GNU General Public License for more details. 343 344 You should have received a copy of the GNU General Public License along 345 with this program; if not, write to the Free Software Foundation, Inc., 346 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA. 347 348 Also add information on how to contact you by electronic and paper mail. 349 350 If the program is interactive, make it output a short notice like this 351 when it starts in an interactive mode: 352 353 Gnomovision version 69, Copyright (C) year name of author 354 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. 355 This is free software, and you are welcome to redistribute it 356 under certain conditions; type `show c' for details. 357 358 The hypothetical commands `show w' and `show c' should show the appropriate 359 parts of the General Public License. Of course, the commands you use may 360 be called something other than `show w' and `show c'; they could even be 361 mouse-clicks or menu items--whatever suits your program. 362 363 You should also get your employer (if you work as a programmer) or your 364 school, if any, to sign a "copyright disclaimer" for the program, if 365 necessary. Here is a sample; alter the names: 366 367 Yoyodyne, Inc., hereby disclaims all copyright interest in the program 368 `Gnomovision' (which makes passes at compilers) written by James Hacker. 369 370 <signature of Ty Coon>, 1 April 1989 371 Ty Coon, President of Vice 372 373 This General Public License does not permit incorporating your program into 374 proprietary programs. If your program is a subroutine library, you may 375 consider it more useful to permit linking proprietary applications with the 376 library. If this is what you want to do, use the GNU Lesser General 377 Public License instead of this License. 378 379 WRITTEN OFFER 380 381 The source code for any program binaries or compressed scripts that are 382 included with WordPress can be freely obtained at the following URL: 383 384 https://wordpress.org/download/source/
