By contrast, the GNU General Public 11.16 +License is intended to guarantee your freedom to share and change free 11.17 +software--to make sure the software is free for all its users. This 11.18 +General Public License applies to most of the Free Software 11.19 +Foundation's software and to any other program whose authors commit to 11.20 +using it. (Some other Free Software Foundation software is covered by 11.21 +the GNU Library General Public License instead.) You can apply it to 11.22 +your programs, too. 11.23 + 11.24 + When we speak of free software, we are referring to freedom, not 11.25 +price. Our General Public Licenses are designed to make sure that you 11.26 +have the freedom to distribute copies of free software (and charge for 11.27 +this service if you wish), that you receive source code or can get it 11.28 +if you want it, that you can change the software or use pieces of it 11.29 +in new free programs; and that you know you can do these things. 11.30 + 11.31 + To protect your rights, we need to make restrictions that forbid 11.32 +anyone to deny you these rights or to ask you to surrender the rights. 11.33 +These restrictions translate to certain responsibilities for you if you 11.34 +distribute copies of the software, or if you modify it. 11.35 + 11.36 + For example, if you distribute copies of such a program, whether 11.37 +gratis or for a fee, you must give the recipients all the rights that 11.38 +you have. You must make sure that they, too, receive or can get the 11.39 +source code. And you must show them these terms so they know their 11.40 +rights. 11.41 + 11.42 + We protect your rights with two steps: (1) copyright the software, and 11.43 +(2) offer you this license which gives you legal permission to copy, 11.44 +distribute and/or modify the software. 11.45 + 11.46 + Also, for each author's protection and ours, we want to make certain 11.47 +that everyone understands that there is no warranty for this free 11.48 +software. If the software is modified by someone else and passed on, we 11.49 +want its recipients to know that what they have is not the original, so 11.50 +that any problems introduced by others will not reflect on the original 11.51 +authors' reputations. 11.52 + 11.53 + Finally, any free program is threatened constantly by software 11.54 +patents. We wish to avoid the danger that redistributors of a free 11.55 +program will individually obtain patent licenses, in effect making the 11.56 +program proprietary. To prevent this, we have made it clear that any 11.57 +patent must be licensed for everyone's free use or not licensed at all. 11.58 + 11.59 + The precise terms and conditions for copying, distribution and 11.60 +modification follow. 11.61 + 11.62 + GNU GENERAL PUBLIC LICENSE 11.63 + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 11.64 + 11.65 + 0. This License applies to any program or other work which contains 11.66 +a notice placed by the copyright holder saying it may be distributed 11.67 +under the terms of this General Public License. The "Program", below, 11.68 +refers to any such program or work, and a "work based on the Program" 11.69 +means either the Program or any derivative work under copyright law: 11.70 +that is to say, a work containing the Program or a portion of it, 11.71 +either verbatim or with modifications and/or translated into another 11.72 +language. (Hereinafter, translation is included without limitation in 11.73 +the term "modification".) Each licensee is addressed as "you". 11.74 + 11.75 +Activities other than copying, distribution and modification are not 11.76 +covered by this License; they are outside its scope. The act of 11.77 +running the Program is not restricted, and the output from the Program 11.78 +is covered only if its contents constitute a work based on the 11.79 +Program (independent of having been made by running the Program). 11.80 +Whether that is true depends on what the Program does. 11.81 + 11.82 + 1. You may copy and distribute verbatim copies of the Program's 11.83 +source code as you receive it, in any medium, provided that you 11.84 +conspicuously and appropriately publish on each copy an appropriate 11.85 +copyright notice and disclaimer of warranty; keep intact all the 11.86 +notices that refer to this License and to the absence of any warranty; 11.87 +and give any other recipients of the Program a copy of this License 11.88 +along with the Program. 11.89 + 11.90 +You may charge a fee for the physical act of transferring a copy, and 11.91 +you may at your option offer warranty protection in exchange for a fee. 11.92 + 11.93 + 2. You may modify your copy or copies of the Program or any portion 11.94 +of it, thus forming a work based on the Program, and copy and 11.95 +distribute such modifications or work under the terms of Section 1 11.96 +above, provided that you also meet all of these conditions: 11.97 + 11.98 + a) You must cause the modified files to carry prominent notices 11.99 + stating that you changed the files and the date of any change. 11.100 + 11.101 + b) You must cause any work that you distribute or publish, that in 11.102 + whole or in part contains or is derived from the Program or any 11.103 + part thereof, to be licensed as a whole at no charge to all third 11.104 + parties under the terms of this License. 11.105 + 11.106 + c) If the modified program normally reads commands interactively 11.107 + when run, you must cause it, when started running for such 11.108 + interactive use in the most ordinary way, to print or display an 11.109 + announcement including an appropriate copyright notice and a 11.110 + notice that there is no warranty (or else, saying that you provide 11.111 + a warranty) and that users may redistribute the program under 11.112 + these conditions, and telling the user how to view a copy of this 11.113 + License. (Exception: if the Program itself is interactive but 11.114 + does not normally print such an announcement, your work based on 11.115 + the Program is not required to print an announcement.) 11.116 + 11.117 +These requirements apply to the modified work as a whole. If 11.118 +identifiable sections of that work are not derived from the Program, 11.119 +and can be reasonably considered independent and separate works in 11.120 +themselves, then this License, and its terms, do not apply to those 11.121 +sections when you distribute them as separate works. But when you 11.122 +distribute the same sections as part of a whole which is a work based 11.123 +on the Program, the distribution of the whole must be on the terms of 11.124 +this License, whose permissions for other licensees extend to the 11.125 +entire whole, and thus to each and every part regardless of who wrote it. 11.126 + 11.127 +Thus, it is not the intent of this section to claim rights or contest 11.128 +your rights to work written entirely by you; rather, the intent is to 11.129 +exercise the right to control the distribution of derivative or 11.130 +collective works based on the Program. 11.131 + 11.132 +In addition, mere aggregation of another work not based on the Program 11.133 +with the Program (or with a work based on the Program) on a volume of 11.134 +a storage or distribution medium does not bring the other work under 11.135 +the scope of this License. 11.136 + 11.137 + 3. You may copy and distribute the Program (or a work based on it, 11.138 +under Section 2) in object code or executable form under the terms of 11.139 +Sections 1 and 2 above provided that you also do one of the following: 11.140 + 11.141 + a) Accompany it with the complete corresponding machine-readable 11.142 + source code, which must be distributed under the terms of Sections 11.143 + 1 and 2 above on a medium customarily used for software interchange; or, 11.144 + 11.145 + b) Accompany it with a written offer, valid for at least three 11.146 + years, to give any third party, for a charge no more than your 11.147 + cost of physically performing source distribution, a complete 11.148 + machine-readable copy of the corresponding source code, to be 11.149 + distributed under the terms of Sections 1 and 2 above on a medium 11.150 + customarily used for software interchange; or, 11.151 + 11.152 + c) Accompany it with the information you received as to the offer 11.153 + to distribute corresponding source code. (This alternative is 11.154 + allowed only for noncommercial distribution and only if you 11.155 + received the program in object code or executable form with such 11.156 + an offer, in accord with Subsection b above.) 11.157 + 11.158 +The source code for a work means the preferred form of the work for 11.159 +making modifications to it. For an executable work, complete source 11.160 +code means all the source code for all modules it contains, plus any 11.161 +associated interface definition files, plus the scripts used to 11.162 +control compilation and installation of the executable. However, as a 11.163 +special exception, the source code distributed need not include 11.164 +anything that is normally distributed (in either source or binary 11.165 +form) with the major components (compiler, kernel, and so on) of the 11.166 +operating system on which the executable runs, unless that component 11.167 +itself accompanies the executable. 11.168 + 11.169 +If distribution of executable or object code is made by offering 11.170 +access to copy from a designated place, then offering equivalent 11.171 +access to copy the source code from the same place counts as 11.172 +distribution of the source code, even though third parties are not 11.173 +compelled to copy the source along with the object code. 11.174 + 11.175 + 4. You may not copy, modify, sublicense, or distribute the Program 11.176 +except as expressly provided under this License. Any attempt 11.177 +otherwise to copy, modify, sublicense or distribute the Program is 11.178 +void, and will automatically terminate your rights under this License. 11.179 +However, parties who have received copies, or rights, from you under 11.180 +this License will not have their licenses terminated so long as such 11.181 +parties remain in full compliance. 11.182 + 11.183 + 5. You are not required to accept this License, since you have not 11.184 +signed it. However, nothing else grants you permission to modify or 11.185 +distribute the Program or its derivative works. These actions are 11.186 +prohibited by law if you do not accept this License. Therefore, by 11.187 +modifying or distributing the Program (or any work based on the 11.188 +Program), you indicate your acceptance of this License to do so, and 11.189 +all its terms and conditions for copying, distributing or modifying 11.190 +the Program or works based on it. 11.191 + 11.192 + 6. Each time you redistribute the Program (or any work based on the 11.193 +Program), the recipient automatically receives a license from the 11.194 +original licensor to copy, distribute or modify the Program subject to 11.195 +these terms and conditions. You may not impose any further 11.196 +restrictions on the recipients' exercise of the rights granted herein. 11.197 +You are not responsible for enforcing compliance by third parties to 11.198 +this License. 11.199 + 11.200 + 7. If, as a consequence of a court judgment or allegation of patent 11.201 +infringement or for any other reason (not limited to patent issues), 11.202 +conditions are imposed on you (whether by court order, agreement or 11.203 +otherwise) that contradict the conditions of this License, they do not 11.204 +excuse you from the conditions of this License. If you cannot 11.205 +distribute so as to satisfy simultaneously your obligations under this 11.206 +License and any other pertinent obligations, then as a consequence you 11.207 +may not distribute the Program at all. For example, if a patent 11.208 +license would not permit royalty-free redistribution of the Program by 11.209 +all those who receive copies directly or indirectly through you, then 11.210 +the only way you could satisfy both it and this License would be to 11.211 +refrain entirely from distribution of the Program. 11.212 + 11.213 +If any portion of this section is held invalid or unenforceable under 11.214 +any particular circumstance, the balance of the section is intended to 11.215 +apply and the section as a whole is intended to apply in other 11.216 +circumstances. 11.217 + 11.218 +It is not the purpose of this section to induce you to infringe any 11.219 +patents or other property right claims or to contest validity of any 11.220 +such claims; this section has the sole purpose of protecting the 11.221 +integrity of the free software distribution system, which is 11.222 +implemented by public license practices. Many people have made 11.223 +generous contributions to the wide range of software distributed 11.224 +through that system in reliance on consistent application of that 11.225 +system; it is up to the author/donor to decide if he or she is willing 11.226 +to distribute software through any other system and a licensee cannot 11.227 +impose that choice. 11.228 + 11.229 +This section is intended to make thoroughly clear what is believed to 11.230 +be a consequence of the rest of this License. 11.231 + 11.232 + 8. If the distribution and/or use of the Program is restricted in 11.233 +certain countries either by patents or by copyrighted interfaces, the 11.234 +original copyright holder who places the Program under this License 11.235 +may add an explicit geographical distribution limitation excluding 11.236 +those countries, so that distribution is permitted only in or among 11.237 +countries not thus excluded. In such case, this License incorporates 11.238 +the limitation as if written in the body of this License. 11.239 + 11.240 + 9. The Free Software Foundation may publish revised and/or new versions 11.241 +of the General Public License from time to time. Such new versions will 11.242 +be similar in spirit to the present version, but may differ in detail to 11.243 +address new problems or concerns. 11.244 + 11.245 +Each version is given a distinguishing version number. If the Program 11.246 +specifies a version number of this License which applies to it and "any 11.247 +later version", you have the option of following the terms and conditions 11.248 +either of that version or of any later version published by the Free 11.249 +Software Foundation. If the Program does not specify a version number of 11.250 +this License, you may choose any version ever published by the Free Software 11.251 +Foundation. 11.252 + 11.253 + 10. If you wish to incorporate parts of the Program into other free 11.254 +programs whose distribution conditions are different, write to the author 11.255 +to ask for permission. For software which is copyrighted by the Free 11.256 +Software Foundation, write to the Free Software Foundation; we sometimes 11.257 +make exceptions for this. Our decision will be guided by the two goals 11.258 +of preserving the free status of all derivatives of our free software and 11.259 +of promoting the sharing and reuse of software generally. 11.260 + 11.261 + NO WARRANTY 11.262 + 11.263 + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY 11.264 +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN 11.265 +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES 11.266 +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED 11.267 +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF 11.268 +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS 11.269 +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE 11.270 +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, 11.271 +REPAIR OR CORRECTION. 11.272 + 11.273 + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 11.274 +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR 11.275 +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, 11.276 +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING 11.277 +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED 11.278 +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY 11.279 +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER 11.280 +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE 11.281 +POSSIBILITY OF SUCH DAMAGES. 11.282 + 11.283 + END OF TERMS AND CONDITIONS 11.284 + 11.285 + How to Apply These Terms to Your New Programs 11.286 + 11.287 + If you develop a new program, and you want it to be of the greatest 11.288 +possible use to the public, the best way to achieve this is to make it 11.289 +free software which everyone can redistribute and change under these terms. 11.290 + 11.291 + To do so, attach the following notices to the program. It is safest 11.292 +to attach them to the start of each source file to most effectively 11.293 +convey the exclusion of warranty; and each file should have at least 11.294 +the "copyright" line and a pointer to where the full notice is found. 11.295 + 11.296 + <one line to give the program's name and a brief idea of what it does.> 11.297 + Copyright (C) <year> <name of author> 11.298 + 11.299 + This program is free software; you can redistribute it and/or modify 11.300 + it under the terms of the GNU General Public License as published by 11.301 + the Free Software Foundation; either version 2 of the License, or 11.302 + (at your option) any later version. 11.303 + 11.304 + This program is distributed in the hope that it will be useful, 11.305 + but WITHOUT ANY WARRANTY; without even the implied warranty of 11.306 + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
