|---|
| | 8 | |
|---|
| | 9 | Everyone is permitted to copy and distribute verbatim copies |
|---|
| | 10 | of this license document, but changing it is not allowed. |
|---|

|---|
| | 12 | Preamble |
|---|
| | 13 | ======== |
|---|
| | 14 | |
|---|
| | 15 | The licenses for most software are designed to take away your freedom |
|---|
| | 16 | to share and change it. By contrast, the GNU General Public License is |
|---|
| | 17 | intended to guarantee your freedom to share and change free |
|---|
| | 18 | software--to make sure the software is free for all its users. This |
|---|
| | 19 | General Public License applies to most of the Free Software |
|---|
| | 20 | Foundation's software and to any other program whose authors commit to |
|---|
| | 21 | using it. (Some other Free Software Foundation software is covered by |
|---|
| | 22 | the GNU Library General Public License instead.) You can apply it to |
|---|
| | 23 | your programs, too. |
|---|
| | 24 | |
|---|
| | 25 | When we speak of free software, we are referring to freedom, not price. |
|---|
| | 26 | Our General Public Licenses are designed to make sure that you have |
|---|
| | 27 | the freedom to distribute copies of free software (and charge for this |
|---|
| | 28 | service if you wish), that you receive source code or can get it if you |
|---|
| | 29 | want it, that you can change the software or use pieces of it in new |
|---|
| | 30 | free programs; and that you know you can do these things. |
|---|
| | 31 | |
|---|
| | 32 | To protect your rights, we need to make restrictions that forbid anyone |
|---|
| | 33 | to deny you these rights or to ask you to surrender the rights. These |
|---|
| | 34 | restrictions translate to certain responsibilities for you if you |
|---|
| | 35 | distribute copies of the software, or if you modify it. |
|---|
| | 36 | |
|---|
| | 37 | For example, if you distribute copies of such a program, whether gratis |
|---|
| | 38 | or for a fee, you must give the recipients all the rights that you |
|---|
| | 39 | have. You must make sure that they, too, receive or can get the source |
|---|
| | 40 | code. And you must show them these terms so they know their rights. |
|---|
| | 41 | |
|---|
| | 42 | We protect your rights with two steps: (1) copyright the software, and |
|---|
| | 43 | (2) offer you this license which gives you legal permission to copy, |
|---|
| | 44 | distribute and/or modify the software. |
|---|
| | 45 | |
|---|
| | 46 | Also, for each author's protection and ours, we want to make certain |
|---|
| | 47 | that everyone understands that there is no warranty for this free |
|---|
| | 48 | software. If the software is modified by someone else and passed on, we |
|---|
| | 49 | want its recipients to know that what they have is not the original, so |
|---|
| | 50 | that any problems introduced by others will not reflect on the original |
|---|
| | 51 | authors' reputations. |
|---|
| | 52 | |
|---|
| | 53 | Finally, any free program is threatened constantly by software patents. |
|---|
| | 54 | We wish to avoid the danger that redistributors of a free program will |
|---|
| | 55 | individually obtain patent licenses, in effect making the program |
|---|
| | 56 | proprietary. To prevent this, we have made it clear that any patent |
|---|
| | 57 | must be licensed for everyone's free use or not licensed at all. |
|---|
| | 58 | |
|---|
| | 59 | The precise terms and conditions for copying, distribution and |
|---|
| | 60 | modification follow. |
|---|
| | 61 | |
|---|
| | 62 | GNU GENERAL PUBLIC LICENSE |
|---|
| | 63 | |
|---|
| | 64 | TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION |
|---|
| | 65 | |
|---|
| | 66 | 0. This License applies to any program or other work which contains a |
|---|
| | 67 | notice placed by the copyright holder saying it may be distributed |
|---|
| | 68 | under the terms of this General Public License. The "Program", |
|---|
| | 69 | below, refers to any such program or work, and a "work based on |
|---|
| | 70 | the Program" means either the Program or any derivative work under |
|---|
| | 71 | copyright law: that is to say, a work containing the Program or a |
|---|
| | 72 | portion of it, either verbatim or with modifications and/or |
|---|
| | 73 | translated into another language. (Hereinafter, translation is |
|---|
| | 74 | included without limitation in the term "modification".) Each |
|---|
| | 75 | licensee is addressed as "you". |
|---|
| | 76 | |
|---|
| | 77 | Activities other than copying, distribution and modification are |
|---|
| | 78 | not covered by this License; they are outside its scope. The act |
|---|
| | 79 | of running the Program is not restricted, and the output from the |
|---|
| | 80 | Program is covered only if its contents constitute a work based on |
|---|
| | 81 | the Program (independent of having been made by running the |
|---|
| | 82 | Program). Whether that is true depends on what the Program does. |
|---|
| | 83 | |
|---|
| | 84 | 1. You may copy and distribute verbatim copies of the Program's |
|---|
| | 85 | source code as you receive it, in any medium, provided that you |
|---|
| | 86 | conspicuously and appropriately publish on each copy an appropriate |
|---|
| | 87 | copyright notice and disclaimer of warranty; keep intact all the |
|---|
| | 88 | notices that refer to this License and to the absence of any |
|---|
| | 89 | warranty; and give any other recipients of the Program a copy of |
|---|
| | 90 | this License along with the Program. |
|---|
| | 91 | |
|---|
| | 92 | You may charge a fee for the physical act of transferring a copy, |
|---|
| | 93 | and you may at your option offer warranty protection in exchange |
|---|
| | 94 | for a fee. |
|---|
| | 95 | |
|---|
| | 96 | 2. You may modify your copy or copies of the Program or any portion |
|---|
| | 97 | of it, thus forming a work based on the Program, and copy and |
|---|
| | 98 | distribute such modifications or work under the terms of Section 1 |
|---|
| | 99 | above, provided that you also meet all of these conditions: |
|---|
| | 100 | |
|---|
| | 101 | a. You must cause the modified files to carry prominent notices |
|---|
| | 102 | stating that you changed the files and the date of any change. |
|---|
| | 103 | |
|---|
| | 104 | b. You must cause any work that you distribute or publish, that |
|---|
| | 105 | in whole or in part contains or is derived from the Program |
|---|
| | 106 | or any part thereof, to be licensed as a whole at no charge |
|---|
| | 107 | to all third parties under the terms of this License. |
|---|
| | 108 | |
|---|
| | 109 | c. If the modified program normally reads commands interactively |
|---|
| | 110 | when run, you must cause it, when started running for such |
|---|
| | 111 | interactive use in the most ordinary way, to print or display |
|---|
| | 112 | an announcement including an appropriate copyright notice and |
|---|
| | 113 | a notice that there is no warranty (or else, saying that you |
|---|
| | 114 | provide a warranty) and that users may redistribute the |
|---|
| | 115 | program under these conditions, and telling the user how to |
|---|
| | 116 | view a copy of this License. (Exception: if the Program |
|---|
| | 117 | itself is interactive but does not normally print such an |
|---|
| | 118 | announcement, your work based on the Program is not required |
|---|
| | 119 | to print an announcement.) |
|---|
| | 120 | |
|---|
| | 121 | These requirements apply to the modified work as a whole. If |
|---|
| | 122 | identifiable sections of that work are not derived from the |
|---|
| | 123 | Program, and can be reasonably considered independent and separate |
|---|
| | 124 | works in themselves, then this License, and its terms, do not |
|---|
| | 125 | apply to those sections when you distribute them as separate |
|---|
| | 126 | works. But when you distribute the same sections as part of a |
|---|
| | 127 | whole which is a work based on the Program, the distribution of |
|---|
| | 128 | the whole must be on the terms of this License, whose permissions |
|---|
| | 129 | for other licensees extend to the entire whole, and thus to each |
|---|
| | 130 | and every part regardless of who wrote it. |
|---|
| | 131 | |
|---|
| | 132 | Thus, it is not the intent of this section to claim rights or |
|---|
| | 133 | contest your rights to work written entirely by you; rather, the |
|---|
| | 134 | intent is to exercise the right to control the distribution of |
|---|
| | 135 | derivative or collective works based on the Program. |
|---|
| | 136 | |
|---|
| | 137 | In addition, mere aggregation of another work not based on the |
|---|
| | 138 | Program with the Program (or with a work based on the Program) on |
|---|
| | 139 | a volume of a storage or distribution medium does not bring the |
|---|
| | 140 | other work under the scope of this License. |
|---|
| | 141 | |
|---|
| | 142 | 3. You may copy and distribute the Program (or a work based on it, |
|---|
| | 143 | under Section 2) in object code or executable form under the terms |
|---|
| | 144 | of Sections 1 and 2 above provided that you also do one of the |
|---|
| | 145 | following: |
|---|
| | 146 | |
|---|
| | 147 | a. Accompany it with the complete corresponding machine-readable |
|---|
| | 148 | source code, which must be distributed under the terms of |
|---|
| | 149 | Sections 1 and 2 above on a medium customarily used for |
|---|
| | 150 | software interchange; or, |
|---|
| | 151 | |
|---|
| | 152 | b. Accompany it with a written offer, valid for at least three |
|---|
| | 153 | years, to give any third-party, for a charge no more than your |
|---|
| | 154 | cost of physically performing source distribution, a complete |
|---|
| | 155 | machine-readable copy of the corresponding source code, to be |
|---|
| | 156 | distributed under the terms of Sections 1 and 2 above on a |
|---|
| | 157 | medium customarily used for software interchange; or, |
|---|
| | 158 | |
|---|
| | 159 | c. Accompany it with the information you received as to the offer |
|---|
| | 160 | to distribute corresponding source code. (This alternative is |
|---|
| | 161 | allowed only for noncommercial distribution and only if you |
|---|
| | 162 | received the program in object code or executable form with |
|---|
| | 163 | such an offer, in accord with Subsection b above.) |
|---|
| | 164 | |
|---|
| | 165 | The source code for a work means the preferred form of the work for |
|---|
| | 166 | making modifications to it. For an executable work, complete |
|---|
| | 167 | source code means all the source code for all modules it contains, |
|---|
| | 168 | plus any associated interface definition files, plus the scripts |
|---|
| | 169 | used to control compilation and installation of the executable. |
|---|
| | 170 | However, as a special exception, the source code distributed need |
|---|
| | 171 | not include anything that is normally distributed (in either |
|---|
| | 172 | source or binary form) with the major components (compiler, |
|---|
| | 173 | kernel, and so on) of the operating system on which the executable |
|---|
| | 174 | runs, unless that component itself accompanies the executable. |
|---|
| | 175 | |
|---|
| | 176 | If distribution of executable or object code is made by offering |
|---|
| | 177 | access to copy from a designated place, then offering equivalent |
|---|
| | 178 | access to copy the source code from the same place counts as |
|---|
| | 179 | distribution of the source code, even though third parties are not |
|---|
| | 180 | compelled to copy the source along with the object code. |
|---|
| | 181 | |
|---|
| | 182 | 4. You may not copy, modify, sublicense, or distribute the Program |
|---|
| | 183 | except as expressly provided under this License. Any attempt |
|---|
| | 184 | otherwise to copy, modify, sublicense or distribute the Program is |
|---|
| | 185 | void, and will automatically terminate your rights under this |
|---|
| | 186 | License. However, parties who have received copies, or rights, |
|---|
| | 187 | from you under this License will not have their licenses |
|---|
| | 188 | terminated so long as such parties remain in full compliance. |
|---|
| | 189 | |
|---|
| | 190 | 5. You are not required to accept this License, since you have not |
|---|
| | 191 | signed it. However, nothing else grants you permission to modify |
|---|
| | 192 | or distribute the Program or its derivative works. These actions |
|---|
| | 193 | are prohibited by law if you do not accept this License. |
|---|
| | 194 | Therefore, by modifying or distributing the Program (or any work |
|---|
| | 195 | based on the Program), you indicate your acceptance of this |
|---|
| | 196 | License to do so, and all its terms and conditions for copying, |
|---|
| | 197 | distributing or modifying the Program or works based on it. |
|---|
| | 198 | |
|---|
| | 199 | 6. Each time you redistribute the Program (or any work based on the |
|---|
| | 200 | Program), the recipient automatically receives a license from the |
|---|
| | 201 | original licensor to copy, distribute or modify the Program |
|---|
| | 202 | subject to these terms and conditions. You may not impose any |
|---|
| | 203 | further restrictions on the recipients' exercise of the rights |
|---|
| | 204 | granted herein. You are not responsible for enforcing compliance |
|---|
| | 205 | by third parties to this License. |
|---|
| | 206 | |
|---|
| | 207 | 7. If, as a consequence of a court judgment or allegation of patent |
|---|
| | 208 | infringement or for any other reason (not limited to patent |
|---|
| | 209 | issues), conditions are imposed on you (whether by court order, |
|---|
| | 210 | agreement or otherwise) that contradict the conditions of this |
|---|
| | 211 | License, they do not excuse you from the conditions of this |
|---|
| | 212 | License. If you cannot distribute so as to satisfy simultaneously |
|---|
| | 213 | your obligations under this License and any other pertinent |
|---|
| | 214 | obligations, then as a consequence you may not distribute the |
|---|
| | 215 | Program at all. For example, if a patent license would not permit |
|---|
| | 216 | royalty-free redistribution of the Program by all those who |
|---|
| | 217 | receive copies directly or indirectly through you, then the only |
|---|
| | 218 | way you could satisfy both it and this License would be to refrain |
|---|
| | 219 | entirely from distribution of the Program. |
|---|
| | 220 | |
|---|
| | 221 | If any portion of this section is held invalid or unenforceable |
|---|
| | 222 | under any particular circumstance, the balance of the section is |
|---|
| | 223 | intended to apply and the section as a whole is intended to apply |
|---|
| | 224 | in other circumstances. |
|---|
| | 225 | |
|---|
| | 226 | It is not the purpose of this section to induce you to infringe any |
|---|
| | 227 | patents or other property right claims or to contest validity of |
|---|
| | 228 | any such claims; this section has the sole purpose of protecting |
|---|
| | 229 | the integrity of the free software distribution system, which is |
|---|
| | 230 | implemented by public license practices. Many people have made |
|---|
| | 231 | generous contributions to the wide range of software distributed |
|---|
| | 232 | through that system in reliance on consistent application of that |
|---|
| | 233 | system; it is up to the author/donor to decide if he or she is |
|---|
| | 234 | willing to distribute software through any other system and a |
|---|
| | 235 | licensee cannot impose that choice. |
|---|
| | 236 | |
|---|
| | 237 | This section is intended to make thoroughly clear what is believed |
|---|
| | 238 | to be a consequence of the rest of this License. |
|---|
| | 239 | |
|---|
| | 240 | 8. If the distribution and/or use of the Program is restricted in |
|---|
| | 241 | certain countries either by patents or by copyrighted interfaces, |
|---|
| | 242 | the original copyright holder who places the Program under this |
|---|
| | 243 | License may add an explicit geographical distribution limitation |
|---|
| | 244 | excluding those countries, so that distribution is permitted only |
|---|
| | 245 | in or among countries not thus excluded. In such case, this |
|---|
| | 246 | License incorporates the limitation as if written in the body of |
|---|
| | 247 | this License. |
|---|
| | 248 | |
|---|
| | 249 | 9. The Free Software Foundation may publish revised and/or new |
|---|
| | 250 | versions of the General Public License from time to time. Such |
|---|
| | 251 | new versions will be similar in spirit to the present version, but |
|---|
| | 252 | may differ in detail to address new problems or concerns. |
|---|
| | 253 | |
|---|
| | 254 | Each version is given a distinguishing version number. If the |
|---|
| | 255 | Program specifies a version number of this License which applies |
|---|
| | 256 | to it and "any later version", you have the option of following |
|---|
| | 257 | the terms and conditions either of that version or of any later |
|---|
| | 258 | version published by the Free Software Foundation. If the Program |
|---|
| | 259 | does not specify a version number of this License, you may choose |
|---|
| | 260 | any version ever published by the Free Software Foundation. |
|---|
| | 261 | |
|---|
| | 262 | 10. If you wish to incorporate parts of the Program into other free |
|---|
| | 263 | programs whose distribution conditions are different, write to the |
|---|
| | 264 | author to ask for permission. For software which is copyrighted |
|---|
| | 265 | by the Free Software Foundation, write to the Free Software |
|---|
| | 266 | Foundation; we sometimes make exceptions for this. Our decision |
|---|
| | 267 | will be guided by the two goals of preserving the free status of |
|---|
| | 268 | all derivatives of our free software and of promoting the sharing |
|---|
| | 269 | and reuse of software generally. |
|---|
| | 270 | |
|---|
| | 271 | NO WARRANTY |
|---|
| | 272 | |
|---|
| | 273 | 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO |
|---|
| | 274 | WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE |
|---|
| | 275 | LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT |
|---|
| | 276 | HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT |
|---|
| | 277 | WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT |
|---|
| | 278 | NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND |
|---|
| | 279 | FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE |
|---|
| | 280 | QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE |
|---|
| | 281 | PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY |
|---|
| | 282 | SERVICING, REPAIR OR CORRECTION. |
|---|
| | 283 | |
|---|
| | 284 | 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN |
|---|
| | 285 | WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY |
|---|
| | 286 | MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE |
|---|
| | 287 | LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, |
|---|
| | 288 | INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR |
|---|
| | 289 | INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF |
|---|
| | 290 | DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU |
|---|
| | 291 | OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY |
|---|
| | 292 | OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN |
|---|
| | 293 | ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. |
|---|
| | 294 | |
|---|
| | 295 | END OF TERMS AND CONDITIONS |
|---|
| | 296 | |
|---|
| | 297 | How to Apply These Terms to Your New Programs |
|---|
| | 298 | ============================================= |
|---|
| | 299 | |
|---|
| | 300 | If you develop a new program, and you want it to be of the greatest |
|---|
| | 301 | possible use to the public, the best way to achieve this is to make it |
|---|
| | 302 | free software which everyone can redistribute and change under these |
|---|
| | 303 | terms. |
|---|
| | 304 | |
|---|
| | 305 | To do so, attach the following notices to the program. It is safest to |
|---|
| | 306 | attach them to the start of each source file to most effectively convey |
|---|
| | 307 | the exclusion of warranty; and each file should have at least the |
|---|
| | 308 | "copyright" line and a pointer to where the full notice is found. |
|---|
| | 309 | |
|---|
| | 310 | ONE LINE TO GIVE THE PROGRAM'S NAME AND A BRIEF IDEA OF WHAT IT DOES. |
|---|
| | 311 | Copyright (C) YYYY NAME OF AUTHOR |

|---|
| | 321 | GNU General Public License for more details. |
|---|
| | 322 | |
|---|
| | 323 | You should have received a copy of the GNU General Public License |

|---|
| | 327 | Also add information on how to contact you by electronic and paper mail. |
|---|
| | 328 | |
|---|
| | 329 | If the program is interactive, make it output a short notice like this |
|---|

|---|
| | 342 | |
|---|
| | 343 | You should also get your employer (if you work as a programmer) or your |

|---|
| | 345 | necessary. Here is a sample; alter the names: |
