This code is combined with third-party code<br> 16 that was originally released under licenses which the Free Software Foundation<br> 17 considers incompatible with the GPL, such as the Apache License 2.0, the OpenSSL<br> 18 license, the Mozilla Public License (MPL) and the Slirp license. (Please see the<br> 19 VirtualBox User Manual for a complete list of third-party code and their<br> 20 licenses.) As a special exception to the terms and conditions of the GPL listed<br> 21 below, Oracle gives you explicit permission to combine its GPL code contained in<br> 22 VirtualBox OSE with third-party code under the aforementioned licenses. You may<br> 23 copy and distribute such a combination provided that you adhere to the terms and<br> 24 conditions of all of the GPL and the licenses of the third-party code; in<br> 25 particular, you must include the source code of the entire combination insofar<br> 26 as the GPL requires distribution of source code.<br> 27 <br> 28 2) The GPL listed below does not bind software which uses VirtualBox services by<br> 29 merely linking to VirtualBox libraries so long as all VirtualBox interfaces used<br> 30 by that software are multi-licensed. A VirtualBox interface is deemed<br> 31 multi-licensed if it is declared in a VirtualBox header file that is licensed<br> 32 under both the GPL version 2 (below) *and* the Common Development and<br> 33 Distribution License Version 1.0 (CDDL), as it comes in the "COPYING.CDDL" file.<br> 34 In other words, calling such a multi-licensed interface is merely considered<br> 35 normal use of VirtualBox and does not turn the calling code into a derived work<br> 36 of VirtualBox. In particular, this applies to code that wants to extend<br> 37 VirtualBox by way of the Extension Pack mechanism declared in the ExtPack.h<br> 38 header file.<br> 39 <br> 40 3) Whoever creates or distributes a derived work based on VirtualBox OSE is not<br> 41 obligated to grant the above exceptions for such a version. The GPL allows for<br> 42 releasing a modified version without the above exception; in addition, Oracle<br> 43 hereby also allows you to release a modified version which carries forward these<br> 44 exceptions.<br> 45 <br> 46 Oracle Corporation<br> 47 <br> 48 -------------------------------------------------------<br> 49 <br> 50 GNU GENERAL PUBLIC LICENSE<br> 51 Version 2, June 1991<br> 52 <br> 53 Copyright (C) 1989, 1991 Free Software Foundation, Inc.,<br> 54 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA<br> 55 Everyone is permitted to copy and distribute verbatim copies<br> 56 of this license document, but changing it is not allowed.<br> 57 <br> 58 Preamble<br> 59 <br> 60 The licenses for most software are designed to take away your<br> 61 freedom to share and change it. By contrast, the GNU General Public<br> 62 License is intended to guarantee your freedom to share and change free<br> 63 software--to make sure the software is free for all its users. This<br> 64 General Public License applies to most of the Free Software<br> 65 Foundation's software and to any other program whose authors commit to<br> 66 using it. (Some other Free Software Foundation software is covered by<br> 67 the GNU Lesser General Public License instead.) You can apply it to<br> 68 your programs, too.<br> 69 <br> 70 When we speak of free software, we are referring to freedom, not<br> 71 price. Our General Public Licenses are designed to make sure that you<br> 72 have the freedom to distribute copies of free software (and charge for<br> 73 this service if you wish), that you receive source code or can get it<br> 74 if you want it, that you can change the software or use pieces of it<br> 75 in new free programs; and that you know you can do these things.<br> 76 <br> 77 To protect your rights, we need to make restrictions that forbid<br> 78 anyone to deny you these rights or to ask you to surrender the rights.<br> 79 These restrictions translate to certain responsibilities for you if you<br> 80 distribute copies of the software, or if you modify it.<br> 81 <br> 82 For example, if you distribute copies of such a program, whether<br> 83 gratis or for a fee, you must give the recipients all the rights that<br> 84 you have. You must make sure that they, too, receive or can get the<br> 85 source code. And you must show them these terms so they know their<br> 86 rights.<br> 87 <br> 88 We protect your rights with two steps: (1) copyright the software, and<br> 89 (2) offer you this license which gives you legal permission to copy,<br> 90 distribute and/or modify the software.<br> 91 <br> 92 Also, for each author's protection and ours, we want to make certain<br> 93 that everyone understands that there is no warranty for this free<br> 94 software. If the software is modified by someone else and passed on, we<br> 95 want its recipients to know that what they have is not the original, so<br> 96 that any problems introduced by others will not reflect on the original<br> 97 authors' reputations.<br> 98 <br> 99 Finally, any free program is threatened constantly by software<br> 100 patents. We wish to avoid the danger that redistributors of a free<br> 101 program will individually obtain patent licenses, in effect making the<br> 102 program proprietary. To prevent this, we have made it clear that any<br> 103 patent must be licensed for everyone's free use or not licensed at all.<br> 104 <br> 105 The precise terms and conditions for copying, distribution and<br> 106 modification follow.<br> 107 <br> 108 GNU GENERAL PUBLIC LICENSE<br> 109 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION<br> 110 <br> 111 0. This License applies to any program or other work which contains<br> 112 a notice placed by the copyright holder saying it may be distributed<br> 113 under the terms of this General Public License. The "Program", below,<br> 114 refers to any such program or work, and a "work based on the Program"<br> 115 means either the Program or any derivative work under copyright law:<br> 116 that is to say, a work containing the Program or a portion of it,<br> 117 either verbatim or with modifications and/or translated into another<br> 118 language. (Hereinafter, translation is included without limitation in<br> 119 the term "modification".) Each licensee is addressed as "you".<br> 120 <br> 121 Activities other than copying, distribution and modification are not<br> 122 covered by this License; they are outside its scope. The act of<br> 123 running the Program is not restricted, and the output from the Program<br> 124 is covered only if its contents constitute a work based on the<br> 125 Program (independent of having been made by running the Program).<br> 126 Whether that is true depends on what the Program does.<br> 127 <br> 128 1. You may copy and distribute verbatim copies of the Program's<br> 129 source code as you receive it, in any medium, provided that you<br> 130 conspicuously and appropriately publish on each copy an appropriate<br> 131 copyright notice and disclaimer of warranty; keep intact all the<br> 132 notices that refer to this License and to the absence of any warranty;<br> 133 and give any other recipients of the Program a copy of this License<br> 134 along with the Program.<br> 135 <br> 136 You may charge a fee for the physical act of transferring a copy, and<br> 137 you may at your option offer warranty protection in exchange for a fee.<br> 138 <br> 139 2. You may modify your copy or copies of the Program or any portion<br> 140 of it, thus forming a work based on the Program, and copy and<br> 141 distribute such modifications or work under the terms of Section 1<br> 142 above, provided that you also meet all of these conditions:<br> 143 <br> 144 a) You must cause the modified files to carry prominent notices<br> 145 stating that you changed the files and the date of any change.<br> 146 <br> 147 b) You must cause any work that you distribute or publish, that in<br> 148 whole or in part contains or is derived from the Program or any<br> 149 part thereof, to be licensed as a whole at no charge to all third<br> 150 parties under the terms of this License.<br> 151 <br> 152 c) If the modified program normally reads commands interactively<br> 153 when run, you must cause it, when started running for such<br> 154 interactive use in the most ordinary way, to print or display an<br> 155 announcement including an appropriate copyright notice and a<br> 156 notice that there is no warranty (or else, saying that you provide<br> 157 a warranty) and that users may redistribute the program under<br> 158 these conditions, and telling the user how to view a copy of this<br> 159 License. (Exception: if the Program itself is interactive but<br> 160 does not normally print such an announcement, your work based on<br> 161 the Program is not required to print an announcement.)<br> 162 <br> 163 These requirements apply to the modified work as a whole. If<br> 164 identifiable sections of that work are not derived from the Program,<br> 165 and can be reasonably considered independent and separate works in<br> 166 themselves, then this License, and its terms, do not apply to those<br> 167 sections when you distribute them as separate works. But when you<br> 168 distribute the same sections as part of a whole which is a work based<br> 169 on the Program, the distribution of the whole must be on the terms of<br> 170 this License, whose permissions for other licensees extend to the<br> 171 entire whole, and thus to each and every part regardless of who wrote it.<br> 172 <br> 173 Thus, it is not the intent of this section to claim rights or contest<br> 174 your rights to work written entirely by you; rather, the intent is to<br> 175 exercise the right to control the distribution of derivative or<br> 176 collective works based on the Program.<br> 177 <br> 178 In addition, mere aggregation of another work not based on the Program<br> 179 with the Program (or with a work based on the Program) on a volume of<br> 180 a storage or distribution medium does not bring the other work under<br> 181 the scope of this License.<br> 182 <br> 183 3. You may copy and distribute the Program (or a work based on it,<br> 184 under Section 2) in object code or executable form under the terms of<br> 185 Sections 1 and 2 above provided that you also do one of the following:<br> 186 <br> 187 a) Accompany it with the complete corresponding machine-readable<br> 188 source code, which must be distributed under the terms of Sections<br> 189 1 and 2 above on a medium customarily used for software interchange; or,<br> 190 <br> 191 b) Accompany it with a written offer, valid for at least three<br> 192 years, to give any third party, for a charge no more than your<br> 193 cost of physically performing source distribution, a complete<br> 194 machine-readable copy of the corresponding source code, to be<br> 195 distributed under the terms of Sections 1 and 2 above on a medium<br> 196 customarily used for software interchange; or,<br> 197 <br> 198 c) Accompany it with the information you received as to the offer<br> 199 to distribute corresponding source code. (This alternative is<br> 200 allowed only for noncommercial distribution and only if you<br> 201 received the program in object code or executable form with such<br> 202 an offer, in accord with Subsection b above.)<br> 203 <br> 204 The source code for a work means the preferred form of the work for<br> 205 making modifications to it. For an executable work, complete source<br> 206 code means all the source code for all modules it contains, plus any<br> 207 associated interface definition files, plus the scripts used to<br> 208 control compilation and installation of the executable. However, as a<br> 209 special exception, the source code distributed need not include<br> 210 anything that is normally distributed (in either source or binary<br> 211 form) with the major components (compiler, kernel, and so on) of the<br> 212 operating system on which the executable runs, unless that component<br> 213 itself accompanies the executable.<br> 214 <br> 215 If distribution of executable or object code is made by offering<br> 216 access to copy from a designated place, then offering equivalent<br> 217 access to copy the source code from the same place counts as<br> 218 distribution of the source code, even though third parties are not<br> 219 compelled to copy the source along with the object code.<br> 220 <br> 221 4. You may not copy, modify, sublicense, or distribute the Program<br> 222 except as expressly provided under this License. Any attempt<br> 223 otherwise to copy, modify, sublicense or distribute the Program is<br> 224 void, and will automatically terminate your rights under this License.<br> 225 However, parties who have received copies, or rights, from you under<br> 226 this License will not have their licenses terminated so long as such<br> 227 parties remain in full compliance.<br> 228 <br> 229 5. You are not required to accept this License, since you have not<br> 230 signed it. However, nothing else grants you permission to modify or<br> 231 distribute the Program or its derivative works. These actions are<br> 232 prohibited by law if you do not accept this License. Therefore, by<br> 233 modifying or distributing the Program (or any work based on the<br> 234 Program), you indicate your acceptance of this License to do so, and<br> 235 all its terms and conditions for copying, distributing or modifying<br> 236 the Program or works based on it.<br> 237 <br> 238 6. Each time you redistribute the Program (or any work based on the<br> 239 Program), the recipient automatically receives a license from the<br> 240 original licensor to copy, distribute or modify the Program subject to<br> 241 these terms and conditions. You may not impose any further<br> 242 restrictions on the recipients' exercise of the rights granted herein.<br> 243 You are not responsible for enforcing compliance by third parties to<br> 244 this License.<br> 245 <br> 246 7. If, as a consequence of a court judgment or allegation of patent<br> 247 infringement or for any other reason (not limited to patent issues),<br> 248 conditions are imposed on you (whether by court order, agreement or<br> 249 otherwise) that contradict the conditions of this License, they do not<br> 250 excuse you from the conditions of this License. If you cannot<br> 251 distribute so as to satisfy simultaneously your obligations under this<br> 252 License and any other pertinent obligations, then as a consequence you<br> 253 may not distribute the Program at all. For example, if a patent<br> 254 license would not permit royalty-free redistribution of the Program by<br> 255 all those who receive copies directly or indirectly through you, then<br> 256 the only way you could satisfy both it and this License would be to<br> 257 refrain entirely from distribution of the Program.<br> 258 <br> 259 If any portion of this section is held invalid or unenforceable under<br> 260 any particular circumstance, the balance of the section is intended to<br> 261 apply and the section as a whole is intended to apply in other<br> 262 circumstances.<br> 263 <br> 264 It is not the purpose of this section to induce you to infringe any<br> 265 patents or other property right claims or to contest validity of any<br> 266 such claims; this section has the sole purpose of protecting the<br> 267 integrity of the free software distribution system, which is<br> 268 implemented by public license practices. Many people have made<br> 269 generous contributions to the wide range of software distributed<br> 270 through that system in reliance on consistent application of that<br> 271 system; it is up to the author/donor to decide if he or she is willing<br> 272 to distribute software through any other system and a licensee cannot<br> 273 impose that choice.<br> 274 <br> 275 This section is intended to make thoroughly clear what is believed to<br> 276 be a consequence of the rest of this License.<br> 277 <br> 278 8. If the distribution and/or use of the Program is restricted in<br> 279 certain countries either by patents or by copyrighted interfaces, the<br> 280 original copyright holder who places the Program under this License<br> 281 may add an explicit geographical distribution limitation excluding<br> 282 those countries, so that distribution is permitted only in or among<br> 283 countries not thus excluded. In such case, this License incorporates<br> 284 the limitation as if written in the body of this License.<br> 285 <br> 286 9. The Free Software Foundation may publish revised and/or new versions<br> 287 of the General Public License from time to time. Such new versions will<br> 288 be similar in spirit to the present version, but may differ in detail to<br> 289 address new problems or concerns.<br> 290 <br> 291 Each version is given a distinguishing version number. If the Program<br> 292 specifies a version number of this License which applies to it and "any<br> 293 later version", you have the option of following the terms and conditions<br> 294 either of that version or of any later version published by the Free<br> 295 Software Foundation. If the Program does not specify a version number of<br> 296 this License, you may choose any version ever published by the Free Software<br> 297 Foundation.<br> 298 <br> 299 10. If you wish to incorporate parts of the Program into other free<br> 300 programs whose distribution conditions are different, write to the author<br> 301 to ask for permission. For software which is copyrighted by the Free<br> 302 Software Foundation, write to the Free Software Foundation; we sometimes<br> 303 make exceptions for this. Our decision will be guided by the two goals<br> 304 of preserving the free status of all derivatives of our free software and<br> 305 of promoting the sharing and reuse of software generally.<br> 306 <br> 307 NO WARRANTY<br> 308 <br> 309 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY<br> 310 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN<br> 311 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES<br> 312 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED<br> 313 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF<br> 314 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS<br> 315 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE<br> 316 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,<br> 317 REPAIR OR CORRECTION.<br> 318 <br> 319 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING<br> 320 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR<br> 321 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,<br> 322 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING<br> 323 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED<br> 324 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY<br> 325 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER<br> 326 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE<br> 327 POSSIBILITY OF SUCH DAMAGES.<br> 328 <br> 329 END OF TERMS AND CONDITIONS<br> 330 <br> 331 How to Apply These Terms to Your New Programs<br> 332 <br> 333 If you develop a new program, and you want it to be of the greatest<br> 334 possible use to the public, the best way to achieve this is to make it<br> 335 free software which everyone can redistribute and change under these terms.<br> 336 <br> 337 To do so, attach the following notices to the program. It is safest<br> 338 to attach them to the start of each source file to most effectively<br> 339 convey the exclusion of warranty; and each file should have at least<br> 340 the "copyright" line and a pointer to where the full notice is found.<br> 341 <br> 342 <one line to give the program's name and a brief idea of what it does.><br> 343 Copyright (C) <year> <name of author><br> 344 <br> 345 This program is free software; you can redistribute it and/or modify<br> 346 it under the terms of the GNU General Public License as published by<br> 347 the Free Software Foundation; either version 2 of the License, or<br> 348 (at your option) any later version.<br> 349 <br> 350 This program is distributed in the hope that it will be useful,<br> 351 but WITHOUT ANY WARRANTY; without even the implied warranty of<br> 352 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the<br> 353 GNU General Public License for more details.<br> 354 <br> 355 You should have received a copy of the GNU General Public License along<br> 356 with this program; if not, write to the Free Software Foundation, Inc.,<br> 357 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.<br> 358 <br> 359 Also add information on how to contact you by electronic and paper mail.<br> 360 <br> 361 If the program is interactive, make it output a short notice like this<br> 362 when it starts in an interactive mode:<br> 363 <br> 364 Gnomovision version 69, Copyright (C) year name of author<br> 365 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.<br> 366 This is free software, and you are welcome to redistribute it<br> 367 under certain conditions; type `show c' for details.<br> 368 <br> 369 The hypothetical commands `show w' and `show c' should show the appropriate<br> 370 parts of the General Public License. Of course, the commands you use may<br> 371 be called something other than `show w' and `show c'; they could even be<br> 372 mouse-clicks or menu items--whatever suits your program.<br> 373 <br> 374 You should also get your employer (if you work as a programmer) or your<br> 375 school, if any, to sign a "copyright disclaimer" for the program, if<br> 376 necessary. Here is a sample; alter the names:<br> 377 <br> 378 Yoyodyne, Inc., hereby disclaims all copyright interest in the program<br> 379 `Gnomovision' (which makes passes at compilers) written by James Hacker.<br> 380 <br> 381 <signature of Ty Coon>, 1 April 1989<br> 382 Ty Coon, President of Vice<br> 383 <br> 384 This General Public License does not permit incorporating your program into<br> 385 proprietary programs. If your program is a subroutine library, you may<br> 386 consider it more useful to permit linking proprietary applications with the<br> 387 library. If this is what you want to do, use the GNU Lesser General<br> 388 Public License instead of this License.<br> 10 11 <body lang=EN-US style='word-wrap:break-word'> 12 13 <p>COPYING file for VirtualBox versions 7.0 and later versions 14 that include this file</p> 15 16 <p>Preliminary notes:</p> 17 18 <p style='text-align:justify'>1) The majority of the code in 19 the VirtualBox base package is licensed under the GNU General Public License, 20 version 3 (GPL).

In other words, calling such a multi-licensed 29 interface by dynamically linking to the unmodified VirtualBox libraries is 30 considered a normal use of VirtualBox and does not turn the calling code into a 31 derived work of VirtualBox.

For both users' and authors' sake, the GPL requires that modified 97 versions be marked as changed, so that their problems will not be attributed 98 erroneously to authors of previous versions.</p> 99 100 <p style='text-align:justify'>Some devices are designed to deny 101 users access to install or run modified versions of the software inside them, 102 although the manufacturer can do so. This is fundamentally incompatible with 103 the aim of protecting users' freedom to change the software. The systematic 104 pattern of such abuse occurs in the area of products for individuals to use, 105 which is precisely where it is most unacceptable. Therefore, we have designed 106 this version of the GPL to prohibit the practice for those products. If such 107 problems arise substantially in other domains, we stand ready to extend this 108 provision to those domains in future versions of the GPL, as needed to protect 109 the freedom of users.</p> 110 111 <p style='text-align:justify'>Finally, every program is 112 threatened constantly by software patents. States should not allow patents to 113 restrict development and use of software on general-purpose computers, but in 114 those that do, we wish to avoid the special danger that patents applied to a 115 free program could make it effectively proprietary. To prevent this, the GPL 116 assures that patents cannot be used to render the program non-free.</p> 117 118 <p style='text-align:justify'>The precise terms and conditions 119 for copying, distribution and modification follow.</p> 120 121 <p style='text-align:justify'>TERMS AND CONDITIONS</p> 122 123 <p style='text-align:justify'>0. Definitions.</p> 124 125 <p style='text-align:justify'>“This License” refers to version 126 3 of the GNU General Public License.</p> 127 128 <p style='text-align:justify'>“Copyright” also means 129 copyright-like laws that apply to other kinds of works, such as semiconductor 130 masks.</p> 131 132 <p style='text-align:justify'>“The Program” refers to any 133 copyrightable work licensed under this License. Each licensee is addressed as 134 “you”. “Licensees” and “recipients” may be individuals or organizations.</p> 135 136 <p style='text-align:justify'>To “modify” a work means to copy 137 from or adapt all or part of the work in a fashion requiring copyright 138 permission, other than the making of an exact copy. The resulting work is 139 called a “modified version” of the earlier work or a work “based on” the 140 earlier work.</p> 141 142 <p style='text-align:justify'>A “covered work” means either the 143 unmodified Program or a work based on the Program.</p> 144 145 <p style='text-align:justify'>To “propagate” a work means to do 146 anything with it that, without permission, would make you directly or 147 secondarily liable for infringement under applicable copyright law, except 148 executing it on a computer or modifying a private copy. Propagation includes 149 copying, distribution (with or without modification), making available to the 150 public, and in some countries other activities as well.</p> 151 152 <p style='text-align:justify'>To “convey” a work means any kind 153 of propagation that enables other parties to make or receive copies. Mere 154 interaction with a user through a computer network, with no transfer of a copy, 155 is not conveying.</p> 156 157 <p style='text-align:justify'>An interactive user interface 158 displays “Appropriate Legal Notices” to the extent that it includes a 159 convenient and prominently visible feature that (1) displays an appropriate 160 copyright notice, and (2) tells the user that there is no warranty for the work 161 (except to the extent that warranties are provided), that licensees may convey 162 the work under this License, and how to view a copy of this License. If the 163 interface presents a list of user commands or options, such as a menu, a 164 prominent item in the list meets this criterion.</p> 165 166 <p style='text-align:justify'>1. Source Code.</p> 167 168 <p style='text-align:justify'>The “source code” for a work 169 means the preferred form of the work for making modifications to it. “Object 170 code” means any non-source form of a work.</p> 171 172 <p style='text-align:justify'>A “Standard Interface” means an 173 interface that either is an official standard defined by a recognized standards 174 body, or, in the case of interfaces specified for a particular programming 175 language, one that is widely used among developers working in that language.</p> 176 177 <p style='text-align:justify'>The “System Libraries” of an 178 executable work include anything, other than the work as a whole, that (a) is 179 included in the normal form of packaging a Major Component, but which is not 180 part of that Major Component, and (b) serves only to enable use of the work 181 with that Major Component, or to implement a Standard Interface for which an 182 implementation is available to the public in source code form. A “Major 183 Component”, in this context, means a major essential component (kernel, window 184 system, and so on) of the specific operating system (if any) on which the 185 executable work runs, or a compiler used to produce the work, or an object code 186 interpreter used to run it.</p> 187 188 <p style='text-align:justify'>The “Corresponding Source” for a 189 work in object code form means all the source code needed to generate, install, 190 and (for an executable work) run the object code and to modify the work, 191 including scripts to control those activities. However, it does not include the 192 work's System Libraries, or general-purpose tools or generally available free 193 programs which are used unmodified in performing those activities but which are 194 not part of the work. For example, Corresponding Source includes interface 195 definition files associated with source files for the work, and the source code 196 for shared libraries and dynamically linked subprograms that the work is 197 specifically designed to require, such as by intimate data communication or 198 control flow between those subprograms and other parts of the work.</p> 199 200 <p style='text-align:justify'>The Corresponding Source need not 201 include anything that users can regenerate automatically from other parts of 202 the Corresponding Source.</p> 203 204 <p style='text-align:justify'>The Corresponding Source for a 205 work in source code form is that same work.</p> 206 207 <p style='text-align:justify'>2. Basic Permissions.</p> 208 209 <p style='text-align:justify'>All rights granted under this 210 License are granted for the term of copyright on the Program, and are irrevocable 211 provided the stated conditions are met. This License explicitly affirms your 212 unlimited permission to run the unmodified Program. The output from running a 213 covered work is covered by this License only if the output, given its content, 214 constitutes a covered work. This License acknowledges your rights of fair use 215 or other equivalent, as provided by copyright law.</p> 216 217 <p style='text-align:justify'>You may make, run and propagate 218 covered works that you do not convey, without conditions so long as your 219 license otherwise remains in force. You may convey covered works to others for 220 the sole purpose of having them make modifications exclusively for you, or 221 provide you with facilities for running those works, provided that you comply 222 with the terms of this License in conveying all material for which you do not 223 control copyright. Those thus making or running the covered works for you must 224 do so exclusively on your behalf, under your direction and control, on terms 225 that prohibit them from making any copies of your copyrighted material outside 226 their relationship with you.</p> 227 228 <p style='text-align:justify'>Conveying under any other 229 circumstances is permitted solely under the conditions stated below. 230 Sublicensing is not allowed; section 10 makes it unnecessary.</p> 231 232 <p style='text-align:justify'>3. Protecting Users' Legal Rights 233 From Anti-Circumvention Law.</p> 234 235 <p style='text-align:justify'>No covered work shall be deemed 236 part of an effective technological measure under any applicable law fulfilling 237 obligations under article 11 of the WIPO copyright treaty adopted on 20 238 December 1996, or similar laws prohibiting or restricting circumvention of such 239 measures.</p> 240 241 <p style='text-align:justify'>When you convey a covered work, 242 you waive any legal power to forbid circumvention of technological measures to 243 the extent such circumvention is effected by exercising rights under this 244 License with respect to the covered work, and you disclaim any intention to 245 limit operation or modification of the work as a means of enforcing, against 246 the work's users, your or third parties' legal rights to forbid circumvention 247 of technological measures.</p> 248 249 <p style='text-align:justify'>4. Conveying Verbatim Copies.</p> 250 251 <p style='text-align:justify'>You may convey verbatim copies of 252 the Program's source code as you receive it, in any medium, provided that you 253 conspicuously and appropriately publish on each copy an appropriate copyright 254 notice; keep intact all notices stating that this License and any 255 non-permissive terms added in accord with section 7 apply to the code; keep 256 intact all notices of the absence of any warranty; and give all recipients a 257 copy of this License along with the Program.</p> 258 259 <p style='text-align:justify'>You may charge any price or no 260 price for each copy that you convey, and you may offer support or warranty 261 protection for a fee.</p> 262 263 <p style='text-align:justify'>5. Conveying Modified Source 264 Versions.</p> 265 266 <p style='text-align:justify'>You may convey a work based on 267 the Program, or the modifications to produce it from the Program, in the form 268 of source code under the terms of section 4, provided that you also meet all of 269 these conditions:</p> 270 271 <p style='text-align:justify'> a) The work must carry prominent notices 272 stating that you modified it, and giving a relevant date.</p> 273 274 <p style='text-align:justify'> b) The work must carry prominent notices 275 stating that it is released under this License and any conditions added under 276 section 7. This requirement modifies the requirement in section 4 to “keep 277 intact all notices”.</p> 278 279 <p style='text-align:justify'> c) You must license the entire work, as a 280 whole, under this License to anyone who comes into possession of a copy. This 281 License will therefore apply, along with any applicable section 7 additional 282 terms, to the whole of the work, and all its parts, regardless of how they are 283 packaged. This License gives no permission to license the work in any other 284 way, but it does not invalidate such permission if you have separately received 285 it.</p> 286 287 <p style='text-align:justify'> d) If the work has interactive user 288 interfaces, each must display Appropriate Legal Notices; however, if the 289 Program has interactive interfaces that do not display Appropriate Legal 290 Notices, your work need not make them do so.</p> 291 292 <p style='text-align:justify'>A compilation of a covered work 293 with other separate and independent works, which are not by their nature 294 extensions of the covered work, and which are not combined with it such as to 295 form a larger program, in or on a volume of a storage or distribution medium, 296 is called an “aggregate” if the compilation and its resulting copyright are not 297 used to limit the access or legal rights of the compilation's users beyond what 298 the individual works permit. Inclusion of a covered work in an aggregate does 299 not cause this License to apply to the other parts of the aggregate.</p> 300 301 <p style='text-align:justify'>6. Conveying Non-Source Forms.</p> 302 303 <p style='text-align:justify'>You may convey a covered work in 304 object code form under the terms of sections 4 and 5, provided that you also 305 convey the machine-readable Corresponding Source under the terms of this 306 License, in one of these ways:</p> 307 308 <p style='text-align:justify'> a) Convey the object code in, or embodied 309 in, a physical product (including a physical distribution medium), accompanied 310 by the Corresponding Source fixed on a durable physical medium customarily used 311 for software interchange.</p> 312 313 <p style='text-align:justify'> b) Convey the object code in, or embodied 314 in, a physical product (including a physical distribution medium), accompanied 315 by a written offer, valid for at least three years and valid for as long as you 316 offer spare parts or customer support for that product model, to give anyone 317 who possesses the object code either (1) a copy of the Corresponding Source for 318 all the software in the product that is covered by this License, on a durable 319 physical medium customarily used for software interchange, for a price no more 320 than your reasonable cost of physically performing this conveying of source, or 321 (2) access to copy the Corresponding Source from a network server at no charge.</p> 322 323 <p style='text-align:justify'> c) Convey individual copies of the object 324 code with a copy of the written offer to provide the Corresponding Source. This 325 alternative is allowed only occasionally and noncommercially, and only if you 326 received the object code with such an offer, in accord with subsection 6b.</p> 327 328 <p style='text-align:justify'> d) Convey the object code by offering 329 access from a designated place (gratis or for a charge), and offer equivalent 330 access to the Corresponding Source in the same way through the same place at no 331 further charge. You need not require recipients to copy the Corresponding 332 Source along with the object code. If the place to copy the object code is a 333 network server, the Corresponding Source may be on a different server (operated 334 by you or a third party) that supports equivalent copying facilities, provided you 335 maintain clear directions next to the object code saying where to find the 336 Corresponding Source. Regardless of what server hosts the Corresponding Source, 337 you remain obligated to ensure that it is available for as long as needed to 338 satisfy these requirements.</p> 339 340 <p style='text-align:justify'> e) Convey the object code using 341 peer-to-peer transmission, provided you inform other peers where the object 342 code and Corresponding Source of the work are being offered to the general 343 public at no charge under subsection 6d.</p> 344 345 <p style='text-align:justify'>A separable portion of the object 346 code, whose source code is excluded from the Corresponding Source as a System 347 Library, need not be included in conveying the object code work.</p> 348 349 <p style='text-align:justify'>A “User Product” is either (1) a 350 “consumer product”, which means any tangible personal property which is 351 normally used for personal, family, or household purposes, or (2) anything 352 designed or sold for incorporation into a dwelling. In determining whether a 353 product is a consumer product, doubtful cases shall be resolved in favor of 354 coverage. For a particular product received by a particular user, “normally 355 used” refers to a typical or common use of that class of product, regardless of 356 the status of the particular user or of the way in which the particular user 357 actually uses, or expects or is expected to use, the product. A product is a 358 consumer product regardless of whether the product has substantial commercial, 359 industrial or non-consumer uses, unless such uses represent the only 360 significant mode of use of the product.</p> 361 362 <p style='text-align:justify'>“Installation Information” for a 363 User Product means any methods, procedures, authorization keys, or other 364 information required to install and execute modified versions of a covered work 365 in that User Product from a modified version of its Corresponding Source. The 366 information must suffice to ensure that the continued functioning of the 367 modified object code is in no case prevented or interfered with solely because 368 modification has been made.</p> 369 370 <p style='text-align:justify'>If you convey an object code work 371 under this section in, or with, or specifically for use in, a User Product, and 372 the conveying occurs as part of a transaction in which the right of possession 373 and use of the User Product is transferred to the recipient in perpetuity or 374 for a fixed term (regardless of how the transaction is characterized), the 375 Corresponding Source conveyed under this section must be accompanied by the 376 Installation Information. But this requirement does not apply if neither you 377 nor any third party retains the ability to install modified object code on the 378 User Product (for example, the work has been installed in ROM).</p> 379 380 <p style='text-align:justify'>The requirement to provide 381 Installation Information does not include a requirement to continue to provide 382 support service, warranty, or updates for a work that has been modified or 383 installed by the recipient, or for the User Product in which it has been 384 modified or installed. Access to a network may be denied when the modification 385 itself materially and adversely affects the operation of the network or 386 violates the rules and protocols for communication across the network.</p> 387 388 <p style='text-align:justify'>Corresponding Source conveyed, 389 and Installation Information provided, in accord with this section must be in a 390 format that is publicly documented (and with an implementation available to the 391 public in source code form), and must require no special password or key for 392 unpacking, reading or copying.</p> 393 394 <p style='text-align:justify'>7. Additional Terms.</p> 395 396 <p style='text-align:justify'>“Additional permissions” are 397 terms that supplement the terms of this License by making exceptions from one 398 or more of its conditions. Additional permissions that are applicable to the 399 entire Program shall be treated as though they were included in this License, 400 to the extent that they are valid under applicable law. If additional 401 permissions apply only to part of the Program, that part may be used separately 402 under those permissions, but the entire Program remains governed by this 403 License without regard to the additional permissions.</p> 404 405 <p style='text-align:justify'>When you convey a copy of a 406 covered work, you may at your option remove any additional permissions from 407 that copy, or from any part of it. (Additional permissions may be written to 408 require their own removal in certain cases when you modify the work.) You may 409 place additional permissions on material, added by you to a covered work, for 410 which you have or can give appropriate copyright permission.</p> 411 412 <p style='text-align:justify'>Notwithstanding any other provision 413 of this License, for material you add to a covered work, you may (if authorized 414 by the copyright holders of that material) supplement the terms of this License 415 with terms:</p> 416 417 <p style='text-align:justify'> a) Disclaiming warranty or limiting 418 liability differently from the terms of sections 15 and 16 of this License; or</p> 419 420 <p style='text-align:justify'> b) Requiring preservation of specified 421 reasonable legal notices or author attributions in that material or in the 422 Appropriate Legal Notices displayed by works containing it; or</p> 423 424 <p style='text-align:justify'> c) Prohibiting misrepresentation of the 425 origin of that material, or requiring that modified versions of such material 426 be marked in reasonable ways as different from the original version; or</p> 427 428 <p style='text-align:justify'> d) Limiting the use for publicity purposes 429 of names of licensors or authors of the material; or</p> 430 431 <p style='text-align:justify'> e) Declining to grant rights under 432 trademark law for use of some trade names, trademarks, or service marks; or</p> 433 434 <p style='text-align:justify'> f) Requiring indemnification of licensors 435 and authors of that material by anyone who conveys the material (or modified 436 versions of it) with contractual assumptions of liability to the recipient, for 437 any liability that these contractual assumptions directly impose on those 438 licensors and authors.</p> 439 440 <p style='text-align:justify'>All other non-permissive 441 additional terms are considered “further restrictions” within the meaning of 442 section 10. If the Program as you received it, or any part of it, contains a 443 notice stating that it is governed by this License along with a term that is a 444 further restriction, you may remove that term. If a license document contains a 445 further restriction but permits relicensing or conveying under this License, 446 you may add to a covered work material governed by the terms of that license 447 document, provided that the further restriction does not survive such 448 relicensing or conveying.</p> 449 450 <p style='text-align:justify'>If you add terms to a covered 451 work in accord with this section, you must place, in the relevant source files, 452 a statement of the additional terms that apply to those files, or a notice 453 indicating where to find the applicable terms.</p> 454 455 <p style='text-align:justify'>Additional terms, permissive or 456 non-permissive, may be stated in the form of a separately written license, or 457 stated as exceptions; the above requirements apply either way.</p> 458 459 <p style='text-align:justify'>8. Termination.</p> 460 461 <p style='text-align:justify'>You may not propagate or modify a 462 covered work except as expressly provided under this License. Any attempt 463 otherwise to propagate or modify it is void, and will automatically terminate 464 your rights under this License (including any patent licenses granted under the 465 third paragraph of section 11).</p> 466 467 <p style='text-align:justify'>However, if you cease all 468 violation of this License, then your license from a particular copyright holder 469 is reinstated (a) provisionally, unless and until the copyright holder 470 explicitly and finally terminates your license, and (b) permanently, if the 471 copyright holder fails to notify you of the violation by some reasonable means 472 prior to 60 days after the cessation.</p> 473 474 <p style='text-align:justify'>Moreover, your license from a 475 particular copyright holder is reinstated permanently if the copyright holder 476 notifies you of the violation by some reasonable means, this is the first time 477 you have received notice of violation of this License (for any work) from that 478 copyright holder, and you cure the violation prior to 30 days after your 479 receipt of the notice.</p> 480 481 <p style='text-align:justify'>Termination of your rights under 482 this section does not terminate the licenses of parties who have received 483 copies or rights from you under this License. If your rights have been 484 terminated and not permanently reinstated, you do not qualify to receive new 485 licenses for the same material under section 10.</p> 486 487 <p style='text-align:justify'>9. Acceptance Not Required for 488 Having Copies.</p> 489 490 <p style='text-align:justify'>You are not required to accept 491 this License in order to receive or run a copy of the Program. Ancillary 492 propagation of a covered work occurring solely as a consequence of using 493 peer-to-peer transmission to receive a copy likewise does not require 494 acceptance. However, nothing other than this License grants you permission to 495 propagate or modify any covered work. These actions infringe copyright if you 496 do not accept this License. Therefore, by modifying or propagating a covered 497 work, you indicate your acceptance of this License to do so.</p> 498 499 <p style='text-align:justify'>10. Automatic Licensing of 500 Downstream Recipients.</p> 501 502 <p style='text-align:justify'>Each time you convey a covered 503 work, the recipient automatically receives a license from the original 504 licensors, to run, modify and propagate that work, subject to this License. You 505 are not responsible for enforcing compliance by third parties with this 506 License.</p> 507 508 <p style='text-align:justify'>An “entity transaction” is a 509 transaction transferring control of an organization, or substantially all 510 assets of one, or subdividing an organization, or merging organizations. If 511 propagation of a covered work results from an entity transaction, each party to 512 that transaction who receives a copy of the work also receives whatever 513 licenses to the work the party's predecessor in interest had or could give 514 under the previous paragraph, plus a right to possession of the Corresponding 515 Source of the work from the predecessor in interest, if the predecessor has it 516 or can get it with reasonable efforts.</p> 517 518 <p style='text-align:justify'>You may not impose any further 519 restrictions on the exercise of the rights granted or affirmed under this 520 License. For example, you may not impose a license fee, royalty, or other 521 charge for exercise of rights granted under this License, and you may not 522 initiate litigation (including a cross-claim or counterclaim in a lawsuit) 523 alleging that any patent claim is infringed by making, using, selling, offering 524 for sale, or importing the Program or any portion of it.</p> 525 526 <p style='text-align:justify'>11. Patents.</p> 527 528 <p style='text-align:justify'>A “contributor” is a copyright 529 holder who authorizes use under this License of the Program or a work on which 530 the Program is based. The work thus licensed is called the contributor's 531 “contributor version”.</p> 532 533 <p style='text-align:justify'>A contributor's “essential patent 534 claims” are all patent claims owned or controlled by the contributor, whether 535 already acquired or hereafter acquired, that would be infringed by some manner, 536 permitted by this License, of making, using, or selling its contributor 537 version, but do not include claims that would be infringed only as a 538 consequence of further modification of the contributor version. For purposes of 539 this definition, “control” includes the right to grant patent sublicenses in a 540 manner consistent with the requirements of this License.</p> 541 542 <p style='text-align:justify'>Each contributor grants you a 543 non-exclusive, worldwide, royalty-free patent license under the contributor's 544 essential patent claims, to make, use, sell, offer for sale, import and 545 otherwise run, modify and propagate the contents of its contributor version.</p> 546 547 <p style='text-align:justify'>In the following three 548 paragraphs, a “patent license” is any express agreement or commitment, however 549 denominated, not to enforce a patent (such as an express permission to practice 550 a patent or covenant not to sue for patent infringement). To “grant” such a 551 patent license to a party means to make such an agreement or commitment not to 552 enforce a patent against the party.</p> 553 554 <p style='text-align:justify'>If you convey a covered work, 555 knowingly relying on a patent license, and the Corresponding Source of the work 556 is not available for anyone to copy, free of charge and under the terms of this 557 License, through a publicly available network server or other readily 558 accessible means, then you must either (1) cause the Corresponding Source to be 559 so available, or (2) arrange to deprive yourself of the benefit of the patent 560 license for this particular work, or (3) arrange, in a manner consistent with 561 the requirements of this License, to extend the patent license to downstream 562 recipients. “Knowingly relying” means you have actual knowledge that, but for 563 the patent license, your conveying the covered work in a country, or your recipient's 564 use of the covered work in a country, would infringe one or more identifiable 565 patents in that country that you have reason to believe are valid.</p> 566 567 <p style='text-align:justify'>If, pursuant to or in connection 568 with a single transaction or arrangement, you convey, or propagate by procuring 569 conveyance of, a covered work, and grant a patent license to some of the 570 parties receiving the covered work authorizing them to use, propagate, modify 571 or convey a specific copy of the covered work, then the patent license you 572 grant is automatically extended to all recipients of the covered work and works 573 based on it.</p> 574 575 <p style='text-align:justify'>A patent license is 576 “discriminatory” if it does not include within the scope of its coverage, 577 prohibits the exercise of, or is conditioned on the non-exercise of one or more 578 of the rights that are specifically granted under this License. You may not 579 convey a covered work if you are a party to an arrangement with a third party 580 that is in the business of distributing software, under which you make payment 581 to the third party based on the extent of your activity of conveying the work, 582 and under which the third party grants, to any of the parties who would receive 583 the covered work from you, a discriminatory patent license (a) in connection 584 with copies of the covered work conveyed by you (or copies made from those 585 copies), or (b) primarily for and in connection with specific products or 586 compilations that contain the covered work, unless you entered into that 587 arrangement, or that patent license was granted, prior to 28 March 2007.</p> 588 589 <p style='text-align:justify'>Nothing in this License shall be 590 construed as excluding or limiting any implied license or other defenses to 591 infringement that may otherwise be available to you under applicable patent 592 law.</p> 593 594 <p style='text-align:justify'>12. No Surrender of Others' 595 Freedom.</p> 596 597 <p style='text-align:justify'>If conditions are imposed on you 598 (whether by court order, agreement or otherwise) that contradict the conditions 599 of this License, they do not excuse you from the conditions of this License. If 600 you cannot convey a covered work so as to satisfy simultaneously your 601 obligations under this License and any other pertinent obligations, then as a 602 consequence you may not convey it at all. For example, if you agree to terms 603 that obligate you to collect a royalty for further conveying from those to whom 604 you convey the Program, the only way you could satisfy both those terms and 605 this License would be to refrain entirely from conveying the Program.</p> 606 607 <p style='text-align:justify'>13. Use with the GNU Affero General Public 608 License.</p> 609 610 <p style='text-align:justify'>Notwithstanding any other 611 provision of this License, you have permission to link or combine any covered 612 work with a work licensed under version 3 of the GNU Affero 613 General Public License into a single combined work, and to convey the resulting 614 work. The terms of this License will continue to apply to the part which is the 615 covered work, but the special requirements of the GNU Affero 616 General Public License, section 13, concerning interaction through a network 617 will apply to the combination as such.</p> 618 619 <p style='text-align:justify'>14. Revised Versions of this 620 License.</p> 621 622 <p style='text-align:justify'>The Free Software Foundation may 623 publish revised and/or new versions of the GNU General Public License from time 624 to time. Such new versions will be similar in spirit to the present version, 625 but may differ in detail to address new problems or concerns.</p> 626 627 <p style='text-align:justify'>Each version is given a 628 distinguishing version number. If the Program specifies that a certain numbered 629 version of the GNU General Public License “or any later version” applies to it, 630 you have the option of following the terms and conditions either of that 631 numbered version or of any later version published by the Free Software 632 Foundation. If the Program does not specify a version number of the GNU General 633 Public License, you may choose any version ever published by the Free Software 634 Foundation.</p> 635 636 <p style='text-align:justify'>If the Program specifies that a 637 proxy can decide which future versions of the GNU General Public License can be 638 used, that proxy's public statement of acceptance of a version permanently 639 authorizes you to choose that version for the Program.</p> 640 641 <p style='text-align:justify'>Later license versions may give 642 you additional or different permissions. However, no additional obligations are 643 imposed on any author or copyright holder as a result of your choosing to 644 follow a later version.</p> 645 646 <p style='text-align:justify'>15. Disclaimer of Warranty.</p> 647 648 <p style='text-align:justify'>THERE IS NO WARRANTY FOR THE 649 PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE 650 STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE 651 PROGRAM “AS IS” WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, 652 INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND 653 FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND 654 PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU 655 ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.</p> 656 657 <p style='text-align:justify'>16. Limitation of Liability.</p> 658 659 <p style='text-align:justify'>IN NO EVENT UNLESS REQUIRED BY 660 APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER 661 PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO 662 YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL 663 DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT 664 NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES 665 SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH 666 ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE 667 POSSIBILITY OF SUCH DAMAGES.</p> 668 669 <p style='text-align:justify'>17. Interpretation of Sections 15 670 and 16.</p> 671 672 <p style='text-align:justify'>If the disclaimer of warranty and 673 limitation of liability provided above cannot be given local legal effect 674 according to their terms, reviewing courts shall apply local law that most 675 closely approximates an absolute waiver of all civil liability in connection 676 with the Program, unless a warranty or assumption of liability accompanies a 677 copy of the Program in return for a fee.</p> 678 679 <p style='text-align:justify'>END OF TERMS AND CONDITIONS</p> 680 681 <p style='text-align:justify'>How to Apply These Terms to Your 682 New Programs</p> 683 684 <p style='text-align:justify'>If you develop a new program, and 685 you want it to be of the greatest possible use to the public, the best way to 686 achieve this is to make it free software which everyone can redistribute and 687 change under these terms.</p> 688 689 <p style='text-align:justify'>To do so, attach the following 690 notices to the program. It is safest to attach them to the start of each source 691 file to most effectively state the exclusion of warranty; and each file should 692 have at least the “copyright” line and a pointer to where the full notice is found.</p> 693 694 <p style='text-align:justify'> <one line to give the program's name and 695 a brief idea of what it does.></p> 696 697 <p style='text-align:justify'> Copyright (C) <year> <name of author></p> 698 699 <p style='text-align:justify'> This program is free software: you can 700 redistribute it and/or modify</p> 701 702 <p style='text-align:justify'> it under the terms of the GNU General 703 Public License as published by</p> 704 705 <p style='text-align:justify'> the Free Software Foundation, either 706 version 3 of the License, or</p> 707 708 <p style='text-align:justify'> (at your option) 709 any later version.</p> 710 711 <p style='text-align:justify'> This program is distributed in the hope 712 that it will be useful,</p> 713 714 <p style='text-align:justify'> but WITHOUT ANY WARRANTY; without even the 715 implied warranty of</p> 716 717 <p style='text-align:justify'> MERCHANTABILITY or FITNESS FOR A PARTICULAR 718 PURPOSE.
