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