| 41 | |
| 42 | The GNU General Public License is a free, copyleft license for |
Alexander Afanasyev | 08eecea | 2014-03-28 10:23:30 -0700 | [diff] [blame] | 43 | software and other kinds of works. |
| 44 | |
Davide Pesavento | 16cbadb | 2018-11-23 13:21:39 -0500 | [diff] [blame] | 45 | The licenses for most software and other practical works are designed |
| 46 | to take away your freedom to share and change the works. By contrast, |
| 47 | the GNU General Public License is intended to guarantee your freedom |
| 48 | to share and change all versions of a program--to make sure it remains |
| 49 | free software for all its users. We, the Free Software Foundation, use |
| 50 | the GNU General Public License for most of our software; it applies |
| 51 | also to any other work released this way by its authors. You can apply |
| 52 | it to your programs, too. |
Alexander Afanasyev | 08eecea | 2014-03-28 10:23:30 -0700 | [diff] [blame] | 53 | |
Davide Pesavento | 16cbadb | 2018-11-23 13:21:39 -0500 | [diff] [blame] | 54 | When we speak of free software, we are referring to freedom, not |
| 55 | price. Our General Public Licenses are designed to make sure that you |
Alexander Afanasyev | 08eecea | 2014-03-28 10:23:30 -0700 | [diff] [blame] | 56 | have the freedom to distribute copies of free software (and charge for |
| 57 | them if you wish), that you receive source code or can get it if you |
| 58 | want it, that you can change the software or use pieces of it in new |
| 59 | free programs, and that you know you can do these things. |
| 60 | |
Davide Pesavento | 16cbadb | 2018-11-23 13:21:39 -0500 | [diff] [blame] | 61 | To protect your rights, we need to prevent others from denying you |
| 62 | these rights or asking you to surrender the rights. Therefore, you |
| 63 | have certain responsibilities if you distribute copies of the |
| 64 | software, or if you modify it: responsibilities to respect the freedom |
| 65 | of others. |
Alexander Afanasyev | 08eecea | 2014-03-28 10:23:30 -0700 | [diff] [blame] | 66 | |
Davide Pesavento | 16cbadb | 2018-11-23 13:21:39 -0500 | [diff] [blame] | 67 | For example, if you distribute copies of such a program, whether |
Alexander Afanasyev | 08eecea | 2014-03-28 10:23:30 -0700 | [diff] [blame] | 68 | gratis or for a fee, you must pass on to the recipients the same |
Davide Pesavento | 16cbadb | 2018-11-23 13:21:39 -0500 | [diff] [blame] | 69 | freedoms that you received. You must make sure that they, too, receive |
| 70 | or can get the source code. And you must show them these terms so they |
Alexander Afanasyev | 08eecea | 2014-03-28 10:23:30 -0700 | [diff] [blame] | 71 | know their rights. |
| 72 | |
Davide Pesavento | 16cbadb | 2018-11-23 13:21:39 -0500 | [diff] [blame] | 73 | Developers that use the GNU GPL protect your rights with two steps: |
Alexander Afanasyev | 08eecea | 2014-03-28 10:23:30 -0700 | [diff] [blame] | 74 | (1) assert copyright on the software, and (2) offer you this License |
| 75 | giving you legal permission to copy, distribute and/or modify it. |
| 76 | |
Davide Pesavento | 16cbadb | 2018-11-23 13:21:39 -0500 | [diff] [blame] | 77 | For the developers' and authors' protection, the GPL clearly explains |
| 78 | that there is no warranty for this free software. For both users' and |
Alexander Afanasyev | 08eecea | 2014-03-28 10:23:30 -0700 | [diff] [blame] | 79 | authors' sake, the GPL requires that modified versions be marked as |
| 80 | changed, so that their problems will not be attributed erroneously to |
| 81 | authors of previous versions. |
| 82 | |
Davide Pesavento | 16cbadb | 2018-11-23 13:21:39 -0500 | [diff] [blame] | 83 | Some devices are designed to deny users access to install or run |
| 84 | modified versions of the software inside them, although the |
| 85 | manufacturer can do so. This is fundamentally incompatible with the |
| 86 | aim of protecting users' freedom to change the software. The |
| 87 | systematic pattern of such abuse occurs in the area of products for |
| 88 | individuals to use, which is precisely where it is most unacceptable. |
| 89 | Therefore, we have designed this version of the GPL to prohibit the |
| 90 | practice for those products. If such problems arise substantially in |
| 91 | other domains, we stand ready to extend this provision to those |
| 92 | domains in future versions of the GPL, as needed to protect the |
| 93 | freedom of users. |
Alexander Afanasyev | 08eecea | 2014-03-28 10:23:30 -0700 | [diff] [blame] | 94 | |
Davide Pesavento | 16cbadb | 2018-11-23 13:21:39 -0500 | [diff] [blame] | 95 | Finally, every program is threatened constantly by software patents. |
Alexander Afanasyev | 08eecea | 2014-03-28 10:23:30 -0700 | [diff] [blame] | 96 | States should not allow patents to restrict development and use of |
Davide Pesavento | 16cbadb | 2018-11-23 13:21:39 -0500 | [diff] [blame] | 97 | software on general-purpose computers, but in those that do, we wish |
| 98 | to avoid the special danger that patents applied to a free program |
| 99 | could make it effectively proprietary. To prevent this, the GPL |
| 100 | assures that patents cannot be used to render the program non-free. |
Alexander Afanasyev | 08eecea | 2014-03-28 10:23:30 -0700 | [diff] [blame] | 101 | |
Davide Pesavento | 16cbadb | 2018-11-23 13:21:39 -0500 | [diff] [blame] | 102 | The precise terms and conditions for copying, distribution and |

Alexander Afanasyev | 08eecea | 2014-03-28 10:23:30 -0700 | [diff] [blame] | 116 | "recipients" may be individuals or organizations. |
| 117 | |
Davide Pesavento | 16cbadb | 2018-11-23 13:21:39 -0500 | [diff] [blame] | 118 | To "modify" a work means to copy from or adapt all or part of the work |
| 119 | in a fashion requiring copyright permission, other than the making of |
| 120 | an exact copy. The resulting work is called a "modified version" of |
| 121 | the earlier work or a work "based on" the earlier work. |

Davide Pesavento | 16cbadb | 2018-11-23 13:21:39 -0500 | [diff] [blame] | 123 | A "covered work" means either the unmodified Program or a work based |

| 125 | |
Davide Pesavento | 16cbadb | 2018-11-23 13:21:39 -0500 | [diff] [blame] | 126 | To "propagate" a work means to do anything with it that, without |
Alexander Afanasyev | 08eecea | 2014-03-28 10:23:30 -0700 | [diff] [blame] | 127 | permission, would make you directly or secondarily liable for |
| 128 | infringement under applicable copyright law, except executing it on a |
Davide Pesavento | 16cbadb | 2018-11-23 13:21:39 -0500 | [diff] [blame] | 129 | computer or modifying a private copy. Propagation includes copying, |
Alexander Afanasyev | 08eecea | 2014-03-28 10:23:30 -0700 | [diff] [blame] | 130 | distribution (with or without modification), making available to the |

| 132 | |
Davide Pesavento | 16cbadb | 2018-11-23 13:21:39 -0500 | [diff] [blame] | 133 | To "convey" a work means any kind of propagation that enables other |
| 134 | parties to make or receive copies. Mere interaction with a user |
| 135 | through a computer network, with no transfer of a copy, is not |
| 136 | conveying. |

Alexander Afanasyev | 08eecea | 2014-03-28 10:23:30 -0700 | [diff] [blame] | 140 | feature that (1) displays an appropriate copyright notice, and (2) |
| 141 | tells the user that there is no warranty for the work (except to the |

Alexander Afanasyev | 08eecea | 2014-03-28 10:23:30 -0700 | [diff] [blame] | 164 | "Major Component", in this context, means a major essential component |
| 165 | (kernel, window system, and so on) of the specific operating system |
| 166 | (if any) on which the executable work runs, or a compiler used to |
| 167 | produce the work, or an object code interpreter used to run it. |

Davide Pesavento | 16cbadb | 2018-11-23 13:21:39 -0500 | [diff] [blame] | 169 | The "Corresponding Source" for a work in object code form means all |
Alexander Afanasyev | 08eecea | 2014-03-28 10:23:30 -0700 | [diff] [blame] | 170 | the source code needed to generate, install, and (for an executable |

Davide Pesavento | 16cbadb | 2018-11-23 13:21:39 -0500 | [diff] [blame] | 246 | terms of section 4, provided that you also meet all of these |
| 247 | conditions: |
Alexander Afanasyev | 08eecea | 2014-03-28 10:23:30 -0700 | [diff] [blame] | 248 | |
Davide Pesavento | 16cbadb | 2018-11-23 13:21:39 -0500 | [diff] [blame] | 249 | - a) The work must carry prominent notices stating that you modified |
Alexander Afanasyev | 08eecea | 2014-03-28 10:23:30 -0700 | [diff] [blame] | 250 | it, and giving a relevant date. |
Davide Pesavento | 16cbadb | 2018-11-23 13:21:39 -0500 | [diff] [blame] | 251 | - b) The work must carry prominent notices stating that it is |
| 252 | released under this License and any conditions added under |
| 253 | section 7. This requirement modifies the requirement in section 4 |
| 254 | to "keep intact all notices". |
| 255 | - c) You must license the entire work, as a whole, under this |
| 256 | License to anyone who comes into possession of a copy. This |
Alexander Afanasyev | 08eecea | 2014-03-28 10:23:30 -0700 | [diff] [blame] | 257 | License will therefore apply, along with any applicable section 7 |
| 258 | additional terms, to the whole of the work, and all its parts, |
Davide Pesavento | 16cbadb | 2018-11-23 13:21:39 -0500 | [diff] [blame] | 259 | regardless of how they are packaged. This License gives no |
Alexander Afanasyev | 08eecea | 2014-03-28 10:23:30 -0700 | [diff] [blame] | 260 | permission to license the work in any other way, but it does not |

Davide Pesavento | 16cbadb | 2018-11-23 13:21:39 -0500 | [diff] [blame] | 262 | - d) If the work has interactive user interfaces, each must display |
Alexander Afanasyev | 08eecea | 2014-03-28 10:23:30 -0700 | [diff] [blame] | 263 | Appropriate Legal Notices; however, if the Program has interactive |

Alexander Afanasyev | 08eecea | 2014-03-28 10:23:30 -0700 | [diff] [blame] | 274 | in an aggregate does not cause this License to apply to the other |

Davide Pesavento | 16cbadb | 2018-11-23 13:21:39 -0500 | [diff] [blame] | 284 | - a) Convey the object code in, or embodied in, a physical product |
Alexander Afanasyev | 08eecea | 2014-03-28 10:23:30 -0700 | [diff] [blame] | 285 | (including a physical distribution medium), accompanied by the |

Davide Pesavento | 16cbadb | 2018-11-23 13:21:39 -0500 | [diff] [blame] | 288 | - b) Convey the object code in, or embodied in, a physical product |
Alexander Afanasyev | 08eecea | 2014-03-28 10:23:30 -0700 | [diff] [blame] | 289 | (including a physical distribution medium), accompanied by a |
| 290 | written offer, valid for at least three years and valid for as |
| 291 | long as you offer spare parts or customer support for that product |
| 292 | model, to give anyone who possesses the object code either (1) a |
| 293 | copy of the Corresponding Source for all the software in the |
| 294 | product that is covered by this License, on a durable physical |
| 295 | medium customarily used for software interchange, for a price no |

| 298 | Source from a network server at no charge. |
| 299 | - c) Convey individual copies of the object code with a copy of the |
| 300 | written offer to provide the Corresponding Source. This |
Alexander Afanasyev | 08eecea | 2014-03-28 10:23:30 -0700 | [diff] [blame] | 301 | alternative is allowed only occasionally and noncommercially, and |
| 302 | only if you received the object code with such an offer, in accord |
| 303 | with subsection 6b. |
Davide Pesavento | 16cbadb | 2018-11-23 13:21:39 -0500 | [diff] [blame] | 304 | - d) Convey the object code by offering access from a designated |
Alexander Afanasyev | 08eecea | 2014-03-28 10:23:30 -0700 | [diff] [blame] | 305 | place (gratis or for a charge), and offer equivalent access to the |

Davide Pesavento | 16cbadb | 2018-11-23 13:21:39 -0500 | [diff] [blame] | 307 | further charge. You need not require recipients to copy the |
| 308 | Corresponding Source along with the object code. If the place to |
Alexander Afanasyev | 08eecea | 2014-03-28 10:23:30 -0700 | [diff] [blame] | 309 | copy the object code is a network server, the Corresponding Source |
| 310 | may be on a different server (operated by you or a third party) |
| 311 | that supports equivalent copying facilities, provided you maintain |
| 312 | clear directions next to the object code saying where to find the |
Davide Pesavento | 16cbadb | 2018-11-23 13:21:39 -0500 | [diff] [blame] | 313 | Corresponding Source. Regardless of what server hosts the |
Alexander Afanasyev | 08eecea | 2014-03-28 10:23:30 -0700 | [diff] [blame] | 314 | Corresponding Source, you remain obligated to ensure that it is |
| 315 | available for as long as needed to satisfy these requirements. |
Davide Pesavento | 16cbadb | 2018-11-23 13:21:39 -0500 | [diff] [blame] | 316 | - e) Convey the object code using peer-to-peer transmission, |
| 317 | provided you inform other peers where the object code and |
| 318 | Corresponding Source of the work are being offered to the general |
| 319 | public at no charge under subsection 6d. |

Davide Pesavento | 16cbadb | 2018-11-23 13:21:39 -0500 | [diff] [blame] | 325 | A "User Product" is either (1) a "consumer product", which means any |
| 326 | tangible personal property which is normally used for personal, |
| 327 | family, or household purposes, or (2) anything designed or sold for |
| 328 | incorporation into a dwelling. In determining whether a product is a |
| 329 | consumer product, doubtful cases shall be resolved in favor of |
| 330 | coverage. For a particular product received by a particular user, |
| 331 | "normally used" refers to a typical or common use of that class of |
| 332 | product, regardless of the status of the particular user or of the way |
| 333 | in which the particular user actually uses, or expects or is expected |
| 334 | to use, the product. A product is a consumer product regardless of |
| 335 | whether the product has substantial commercial, industrial or |
| 336 | non-consumer uses, unless such uses represent the only significant |
| 337 | mode of use of the product. |

| 345 | solely because modification has been made. |
Alexander Afanasyev | 08eecea | 2014-03-28 10:23:30 -0700 | [diff] [blame] | 346 | |
Davide Pesavento | 16cbadb | 2018-11-23 13:21:39 -0500 | [diff] [blame] | 347 | If you convey an object code work under this section in, or with, or |

Davide Pesavento | 16cbadb | 2018-11-23 13:21:39 -0500 | [diff] [blame] | 353 | by the Installation Information. But this requirement does not apply |
Alexander Afanasyev | 08eecea | 2014-03-28 10:23:30 -0700 | [diff] [blame] | 354 | if neither you nor any third party retains the ability to install |

Davide Pesavento | 16cbadb | 2018-11-23 13:21:39 -0500 | [diff] [blame] | 358 | The requirement to provide Installation Information does not include a |

Davide Pesavento | 16cbadb | 2018-11-23 13:21:39 -0500 | [diff] [blame] | 641 | If the disclaimer of warranty and limitation of liability provided |
Alexander Afanasyev | 08eecea | 2014-03-28 10:23:30 -0700 | [diff] [blame] | 642 | above cannot be given local legal effect according to their terms, |
| 643 | reviewing courts shall apply local law that most closely approximates |
| 644 | an absolute waiver of all civil liability in connection with the |
| 645 | Program, unless a warranty or assumption of liability accompanies a |
| 646 | copy of the Program in return for a fee. |

Alexander Afanasyev | 08eecea | 2014-03-28 10:23:30 -0700 | [diff] [blame] | 651 | |
Davide Pesavento | 16cbadb | 2018-11-23 13:21:39 -0500 | [diff] [blame] | 652 | If you develop a new program, and you want it to be of the greatest |
Alexander Afanasyev | 08eecea | 2014-03-28 10:23:30 -0700 | [diff] [blame] | 653 | possible use to the public, the best way to achieve this is to make it |
Davide Pesavento | 16cbadb | 2018-11-23 13:21:39 -0500 | [diff] [blame] | 654 | free software which everyone can redistribute and change under these |
| 655 | terms. |
Alexander Afanasyev | 08eecea | 2014-03-28 10:23:30 -0700 | [diff] [blame] | 656 | |
Davide Pesavento | 16cbadb | 2018-11-23 13:21:39 -0500 | [diff] [blame] | 657 | To do so, attach the following notices to the program. It is safest to |
| 658 | attach them to the start of each source file to most effectively state |
| 659 | the exclusion of warranty; and each file should have at least the |
| 660 | "copyright" line and a pointer to where the full notice is found. |

Alexander Afanasyev | 08eecea | 2014-03-28 10:23:30 -0700 | [diff] [blame] | 682 | notice like this when it starts in an interactive mode: |

| 692 | use an "about box". |
