By contrast, the GNU General Public License is intended to 1.18 +guarantee your freedom to share and change free software--to make sure the 1.19 +software is free for all its users. This General Public License applies to 1.20 +most of the Free Software Foundation's software and to any other program whose 1.21 +authors commit to using it. (Some other Free Software Foundation software is 1.22 +covered by the GNU Library General Public License instead.) You can apply it to 1.23 +your programs, too. 1.24 + 1.25 +When we speak of free software, we are referring to freedom, not price. Our 1.26 +General Public Licenses are designed to make sure that you have the freedom to 1.27 +distribute copies of free software (and charge for this service if you wish), 1.28 +that you receive source code or can get it if you want it, that you can change 1.29 +the software or use pieces of it in new free programs; and that you know you 1.30 +can do these things. 1.31 + 1.32 +To protect your rights, we need to make restrictions that forbid anyone to deny 1.33 +you these rights or to ask you to surrender the rights. These restrictions 1.34 +translate to certain responsibilities for you if you distribute copies of the 1.35 +software, or if you modify it. 1.36 + 1.37 +For example, if you distribute copies of such a program, whether gratis or for 1.38 +a fee, you must give the recipients all the rights that you have. You must 1.39 +make sure that they, too, receive or can get the source code. And you must 1.40 +show them these terms so they know their rights. 1.41 + 1.42 +We protect your rights with two steps: (1) copyright the software, and (2) 1.43 +offer you this license which gives you legal permission to copy, distribute 1.44 +and/or modify the software. 1.45 + 1.46 +Also, for each author's protection and ours, we want to make certain that 1.47 +everyone understands that there is no warranty for this free software. If the 1.48 +software is modified by someone else and passed on, we want its recipients to 1.49 +know that what they have is not the original, so that any problems introduced 1.50 +by others will not reflect on the original authors' reputations. 1.51 + 1.52 +Finally, any free program is threatened constantly by software patents. We 1.53 +wish to avoid the danger that redistributors of a free program will 1.54 +individually obtain patent licenses, in effect making the program proprietary. 1.55 +To prevent this, we have made it clear that any patent must be licensed for 1.56 +everyone's free use or not licensed at all. 1.57 + 1.58 +The precise terms and conditions for copying, distribution and modification 1.59 +follow. 1.60 + 1.61 +TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 1.62 + 1.63 +0. This License applies to any program or other work which contains a notice 1.64 +placed by the copyright holder saying it may be distributed under the terms of 1.65 +this General Public License. The "Program", below, refers to any such program 1.66 +or work, and a "work based on the Program" means either the Program or any 1.67 +derivative work under copyright law: that is to say, a work containing the 1.68 +Program or a portion of it, either verbatim or with modifications and/or 1.69 +translated into another language. (Hereinafter, translation is included 1.70 +without limitation in the term "modification".) Each licensee is addressed as 1.71 +"you". 1.72 + 1.73 +Activities other than copying, distribution and modification are not covered by 1.74 +this License; they are outside its scope. The act of running the Program is 1.75 +not restricted, and the output from the Program is covered only if its contents 1.76 +constitute a work based on the Program (independent of having been made by 1.77 +running the Program). Whether that is true depends on what the Program does. 1.78 + 1.79 +1. You may copy and distribute verbatim copies of the Program's source code as 1.80 +you receive it, in any medium, provided that you conspicuously and 1.81 +appropriately publish on each copy an appropriate copyright notice and 1.82 +disclaimer of warranty; keep intact all the notices that refer to this License 1.83 +and to the absence of any warranty; and give any other recipients of the 1.84 +Program a copy of this License along with the Program. 1.85 + 1.86 +You may charge a fee for the physical act of transferring a copy, and you may 1.87 +at your option offer warranty protection in exchange for a fee. 1.88 + 1.89 +2. You may modify your copy or copies of the Program or any portion of it, thus 1.90 +forming a work based on the Program, and copy and distribute such modifications 1.91 +or work under the terms of Section 1 above, provided that you also meet all of 1.92 +these conditions: 1.93 + 1.94 + a) You must cause the modified files to carry prominent notices stating 1.95 + that you changed the files and the date of any change. 1.96 + 1.97 + b) You must cause any work that you distribute or publish, that in whole or 1.98 + in part contains or is derived from the Program or any part thereof, to be 1.99 + licensed as a whole at no charge to all third parties under the terms of 1.100 + this License. 1.101 + 1.102 + c) If the modified program normally reads commands interactively when run, 1.103 + you must cause it, when started running for such interactive use in the 1.104 + most ordinary way, to print or display an announcement including an 1.105 + appropriate copyright notice and a notice that there is no warranty (or 1.106 + else, saying that you provide a warranty) and that users may redistribute 1.107 + the program under these conditions, and telling the user how to view a copy 1.108 + of this License. (Exception: if the Program itself is interactive but does 1.109 + not normally print such an announcement, your work based on the Program is 1.110 + not required to print an announcement.) 1.111 + 1.112 +These requirements apply to the modified work as a whole. If identifiable 1.113 +sections of that work are not derived from the Program, and can be reasonably 1.114 +considered independent and separate works in themselves, then this License, and 1.115 +its terms, do not apply to those sections when you distribute them as separate 1.116 +works. But when you distribute the same sections as part of a whole which is a 1.117 +work based on the Program, the distribution of the whole must be on the terms 1.118 +of this License, whose permissions for other licensees extend to the entire 1.119 +whole, and thus to each and every part regardless of who wrote it. 1.120 + 1.121 +Thus, it is not the intent of this section to claim rights or contest your 1.122 +rights to work written entirely by you; rather, the intent is to exercise the 1.123 +right to control the distribution of derivative or collective works based on 1.124 +the Program. 1.125 + 1.126 +In addition, mere aggregation of another work not based on the Program with the 1.127 +Program (or with a work based on the Program) on a volume of a storage or 1.128 +distribution medium does not bring the other work under the scope of this 1.129 +License. 1.130 + 1.131 +3. You may copy and distribute the Program (or a work based on it, under 1.132 +Section 2) in object code or executable form under the terms of Sections 1 and 1.133 +2 above provided that you also do one of the following: 1.134 + 1.135 + a) Accompany it with the complete corresponding machine-readable source 1.136 + code, which must be distributed under the terms of Sections 1 and 2 above 1.137 + on a medium customarily used for software interchange; or, 1.138 + 1.139 + b) Accompany it with a written offer, valid for at least three years, to 1.140 + give any third party, for a charge no more than your cost of physically 1.141 + performing source distribution, a complete machine-readable copy of the 1.142 + corresponding source code, to be distributed under the terms of Sections 1 1.143 + and 2 above on a medium customarily used for software interchange; or, 1.144 + 1.145 + c) Accompany it with the information you received as to the offer to 1.146 + distribute corresponding source code. (This alternative is allowed only 1.147 + for noncommercial distribution and only if you received the program in 1.148 + object code or executable form with such an offer, in accord with 1.149 + Subsection b above.) 1.150 + 1.151 +The source code for a work means the preferred form of the work for making 1.152 +modifications to it. For an executable work, complete source code means all 1.153 +the source code for all modules it contains, plus any associated interface 1.154 +definition files, plus the scripts used to control compilation and installation 1.155 +of the executable. However, as a special exception, the source code 1.156 +distributed need not include anything that is normally distributed (in either 1.157 +source or binary form) with the major components (compiler, kernel, and so on) 1.158 +of the operating system on which the executable runs, unless that component 1.159 +itself accompanies the executable. 1.160 + 1.161 +If distribution of executable or object code is made by offering access to copy 1.162 +from a designated place, then offering equivalent access to copy the source 1.163 +code from the same place counts as distribution of the source code, even though 1.164 +third parties are not compelled to copy the source along with the object code. 1.165 + 1.166 +4. You may not copy, modify, sublicense, or distribute the Program except as 1.167 +expressly provided under this License. Any attempt otherwise to copy, modify, 1.168 +sublicense or distribute the Program is void, and will automatically terminate 1.169 +your rights under this License. However, parties who have received copies, or 1.170 +rights, from you under this License will not have their licenses terminated so 1.171 +long as such parties remain in full compliance. 1.172 + 1.173 +5. You are not required to accept this License, since you have not signed it. 1.174 +However, nothing else grants you permission to modify or distribute the Program 1.175 +or its derivative works. These actions are prohibited by law if you do not 1.176 +accept this License. Therefore, by modifying or distributing the Program (or 1.177 +any work based on the Program), you indicate your acceptance of this License to 1.178 +do so, and all its terms and conditions for copying, distributing or modifying 1.179 +the Program or works based on it. 1.180 + 1.181 +6. Each time you redistribute the Program (or any work based on the Program), 1.182 +the recipient automatically receives a license from the original licensor to 1.183 +copy, distribute or modify the Program subject to these terms and conditions. 1.184 +You may not impose any further restrictions on the recipients' exercise of the 1.185 +rights granted herein. You are not responsible for enforcing compliance by 1.186 +third parties to this License. 1.187 + 1.188 +7. If, as a consequence of a court judgment or allegation of patent 1.189 +infringement or for any other reason (not limited to patent issues), conditions 1.190 +are imposed on you (whether by court order, agreement or otherwise) that 1.191 +contradict the conditions of this License, they do not excuse you from the 1.192 +conditions of this License. If you cannot distribute so as to satisfy 1.193 +simultaneously your obligations under this License and any other pertinent 1.194 +obligations, then as a consequence you may not distribute the Program at all. 1.195 +For example, if a patent license would not permit royalty-free redistribution 1.196 +of the Program by all those who receive copies directly or indirectly through 1.197 +you, then the only way you could satisfy both it and this License would be to 1.198 +refrain entirely from distribution of the Program. 1.199 + 1.200 +If any portion of this section is held invalid or unenforceable under any 1.201 +particular circumstance, the balance of the section is intended to apply and 1.202 +the section as a whole is intended to apply in other circumstances. 1.203 + 1.204 +It is not the purpose of this section to induce you to infringe any patents or 1.205 +other property right claims or to contest validity of any such claims; this 1.206 +section has the sole purpose of protecting the integrity of the free software 1.207 +distribution system, which is implemented by public license practices. Many 1.208 +people have made generous contributions to the wide range of software 1.209 +distributed through that system in reliance on consistent application of that 1.210 +system; it is up to the author/donor to decide if he or she is willing to 1.211 +distribute software through any other system and a licensee cannot impose that 1.212 +choice. 1.213 + 1.214 +This section is intended to make thoroughly clear what is believed to be a 1.215 +consequence of the rest of this License. 1.216 + 1.217 +8. If the distribution and/or use of the Program is restricted in certain 1.218 +countries either by patents or by copyrighted interfaces, the original 1.219 +copyright holder who places the Program under this License may add an explicit 1.220 +geographical distribution limitation excluding those countries, so that 1.221 +distribution is permitted only in or among countries not thus excluded. In 1.222 +such case, this License incorporates the limitation as if written in the body 1.223 +of this License. 1.224 + 1.225 +9. The Free Software Foundation may publish revised and/or new versions of the 1.226 +General Public License from time to time. Such new versions will be similar in 1.227 +spirit to the present version, but may differ in detail to address new problems 1.228 +or concerns. 1.229 + 1.230 +Each version is given a distinguishing version number. If the Program 1.231 +specifies a version number of this License which applies to it and "any later 1.232 +version", you have the option of following the terms and conditions either of 1.233 +that version or of any later version published by the Free Software Foundation. 1.234 +If the Program does not specify a version number of this License, you may 1.235 +choose any version ever published by the Free Software Foundation. 1.236 + 1.237 +10. If you wish to incorporate parts of the Program into other free programs 1.238 +whose distribution conditions are different, write to the author to ask for 1.239 +permission. For software which is copyrighted by the Free Software Foundation, 1.240 +write to the Free Software Foundation; we sometimes make exceptions for this. 1.241 +Our decision will be guided by the two goals of preserving the free status of 1.242 +all derivatives of our free software and of promoting the sharing and reuse of 1.243 +software generally. 1.244 + 1.245 +NO WARRANTY 1.246 + 1.247 +11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR 1.248 +THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE 1.249 +STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE 1.250 +PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, 1.251 +INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND 1.252 +FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND 1.253 +PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, 1.254 +YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 1.255 + 1.256 +12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL 1.257 +ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE 1.258 +PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY 1.259 +GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR 1.260 +INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA 1.261 +BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A 1.262 +FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER 1.263 +OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. 1.264 + 1.265 +END OF TERMS AND CONDITIONS 1.266 + 1.267 +How to Apply These Terms to Your New Programs 1.268 + 1.269 +If you develop a new program, and you want it to be of the greatest possible 1.270 +use to the public, the best way to achieve this is to make it free software 1.271 +which everyone can redistribute and change under these terms. 1.272 + 1.273 +To do so, attach the following notices to the program. It is safest to attach 1.274 +them to the start of each source file to most effectively convey the exclusion 1.275 +of warranty; and each file should have at least the "copyright" line and a 1.276 +pointer to where the full notice is found. 1.277 + 1.278 + One line to give the program's name and a brief idea of what it does. 1.279 + 1.280 + Copyright (C) <year> <name of author> 1.281 + 1.282 + This program is free software; you can redistribute it and/or modify it 1.283 + under the terms of the GNU General Public License as published by the Free 1.284 + Software Foundation; either version 2 of the License, or (at your option) 1.285 + any later version. 1.286 + 1.287 + This program is distributed in the hope that it will be useful, but WITHOUT 1.288 + ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or 1.289 + FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for 1.290 + more details. 1.291 + 1.292 + You should have received a copy of the GNU General Public License along 1.293 + with this program; if not, write to the Free Software Foundation, Inc., 59 1.294 + Temple Place, Suite 330, Boston, MA 02111-1307 USA 1.295 + 1.296 +Also add information on how to contact you by electronic and paper mail. 1.297 + 1.298 +If the program is interactive, make it output a short notice like this when it 1.299 +starts in an interactive mode: 1.300 + 1.301 + Gnomovision version 69, Copyright (C) year name of author Gnomovision comes 1.302 + with ABSOLUTELY NO WARRANTY; for details type 'show w'. This is free 1.303 + software, and you are welcome to redistribute it under certain conditions; 1.304 + type 'show c' for details. 1.305 + 1.306 +The hypothetical commands 'show w' and 'show c' should show the appropriate 1.307 +parts of the General Public License. Of course, the commands you use may be 1.308 +called something other than 'show w' and 'show c'; they could even be 1.309 +mouse-clicks or menu items--whatever suits your program. 1.310 + 1.311 +You should also get your employer (if you work as a programmer) or your school, 1.312 +if any, to sign a "copyright disclaimer" for the program, if necessary. Here 1.313 +is a sample; alter the names: 1.314 + 1.315 + Yoyodyne, Inc., hereby disclaims all copyright interest in the program 1.316 + 'Gnomovision' (which makes passes at compilers) written by James Hacker. 1.317 + 1.318 + signature of Ty Coon, 1 April 1989 1.319 + 1.320 + Ty Coon, President of Vice 1.321 + 1.322 +This General Public License does not permit incorporating your program into 1.323 +proprietary programs.
