By contrast, the GNU General Public 22 License is intended to guarantee your freedom to share and change free 23 software--to make sure the software is free for all its users. This 24 General Public License applies to most of the Free Software 25 Foundation's software and to any other program whose authors commit to 26 using it. (Some other Free Software Foundation software is covered by 27 the GNU Library General Public License instead.) You can apply it to 28 your programs, too. 29 30 When we speak of free software, we are referring to freedom, not 31 price. Our General Public Licenses are designed to make sure that you 32 have the freedom to distribute copies of free software (and charge for 33 this service if you wish), that you receive source code or can get it 34 if you want it, that you can change the software or use pieces of it 35 in new free programs; and that you know you can do these things. 36 37 To protect your rights, we need to make restrictions that forbid 38 anyone to deny you these rights or to ask you to surrender the rights. 39 These restrictions translate to certain responsibilities for you if you 40 distribute copies of the software, or if you modify it. 41 42 For example, if you distribute copies of such a program, whether 43 gratis or for a fee, you must give the recipients all the rights that 44 you have. You must make sure that they, too, receive or can get the 45 source code. And you must show them these terms so they know their 46 rights. 47 48 We protect your rights with two steps: (1) copyright the software, and 49 (2) offer you this license which gives you legal permission to copy, 50 distribute and/or modify the software. 51 52 Also, for each author's protection and ours, we want to make certain 53 that everyone understands that there is no warranty for this free 54 software. If the software is modified by someone else and passed on, we 55 want its recipients to know that what they have is not the original, so 56 that any problems introduced by others will not reflect on the original 57 authors' reputations. 58 59 Finally, any free program is threatened constantly by software 60 patents. We wish to avoid the danger that redistributors of a free 61 program will individually obtain patent licenses, in effect making the 62 program proprietary. To prevent this, we have made it clear that any 63 patent must be licensed for everyone's free use or not licensed at all. 64 65 The precise terms and conditions for copying, distribution and 66 modification follow. 67 69 GNU GENERAL PUBLIC LICENSE 70 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 71 72 0. This License applies to any program or other work which contains 73 a notice placed by the copyright holder saying it may be distributed 74 under the terms of this General Public License. The "Program", below, 75 refers to any such program or work, and a "work based on the Program" 76 means either the Program or any derivative work under copyright law: 77 that is to say, a work containing the Program or a portion of it, 78 either verbatim or with modifications and/or translated into another 79 language. (Hereinafter, translation is included without limitation in 80 the term "modification".) Each licensee is addressed as "you". 81 82 Activities other than copying, distribution and modification are not 83 covered by this License; they are outside its scope. The act of 84 running the Program is not restricted, and the output from the Program 85 is covered only if its contents constitute a work based on the 86 Program (independent of having been made by running the Program). 87 Whether that is true depends on what the Program does. 88 89 1. You may copy and distribute verbatim copies of the Program's 90 source code as you receive it, in any medium, provided that you 91 conspicuously and appropriately publish on each copy an appropriate 92 copyright notice and disclaimer of warranty; keep intact all the 93 notices that refer to this License and to the absence of any warranty; 94 and give any other recipients of the Program a copy of this License 95 along with the Program. 96 97 You may charge a fee for the physical act of transferring a copy, and 98 you may at your option offer warranty protection in exchange for a fee. 99 100 2. You may modify your copy or copies of the Program or any portion 101 of it, thus forming a work based on the Program, and copy and 102 distribute such modifications or work under the terms of Section 1 103 above, provided that you also meet all of these conditions: 104 105 a) You must cause the modified files to carry prominent notices 106 stating that you changed the files and the date of any change. 107 108 b) You must cause any work that you distribute or publish, that in 109 whole or in part contains or is derived from the Program or any 110 part thereof, to be licensed as a whole at no charge to all third 111 parties under the terms of this License. 112 113 c) If the modified program normally reads commands interactively 114 when run, you must cause it, when started running for such 115 interactive use in the most ordinary way, to print or display an 116 announcement including an appropriate copyright notice and a 117 notice that there is no warranty (or else, saying that you provide 118 a warranty) and that users may redistribute the program under 119 these conditions, and telling the user how to view a copy of this 120 License. (Exception: if the Program itself is interactive but 121 does not normally print such an announcement, your work based on 122 the Program is not required to print an announcement.) 123 125 These requirements apply to the modified work as a whole. If 126 identifiable sections of that work are not derived from the Program, 127 and can be reasonably considered independent and separate works in 128 themselves, then this License, and its terms, do not apply to those 129 sections when you distribute them as separate works. But when you 130 distribute the same sections as part of a whole which is a work based 131 on the Program, the distribution of the whole must be on the terms of 132 this License, whose permissions for other licensees extend to the 133 entire whole, and thus to each and every part regardless of who wrote it. 134 135 Thus, it is not the intent of this section to claim rights or contest 136 your rights to work written entirely by you; rather, the intent is to 137 exercise the right to control the distribution of derivative or 138 collective works based on the Program. 139 140 In addition, mere aggregation of another work not based on the Program 141 with the Program (or with a work based on the Program) on a volume of 142 a storage or distribution medium does not bring the other work under 143 the scope of this License. 144 145 3. You may copy and distribute the Program (or a work based on it, 146 under Section 2) in object code or executable form under the terms of 147 Sections 1 and 2 above provided that you also do one of the following: 148 149 a) Accompany it with the complete corresponding machine-readable 150 source code, which must be distributed under the terms of Sections 151 1 and 2 above on a medium customarily used for software interchange; or, 152 153 b) Accompany it with a written offer, valid for at least three 154 years, to give any third party, for a charge no more than your 155 cost of physically performing source distribution, a complete 156 machine-readable copy of the corresponding source code, to be 157 distributed under the terms of Sections 1 and 2 above on a medium 158 customarily used for software interchange; or, 159 160 c) Accompany it with the information you received as to the offer 161 to distribute corresponding source code. (This alternative is 162 allowed only for noncommercial distribution and only if you 163 received the program in object code or executable form with such 164 an offer, in accord with Subsection b above.) 165 166 The source code for a work means the preferred form of the work for 167 making modifications to it. For an executable work, complete source 168 code means all the source code for all modules it contains, plus any 169 associated interface definition files, plus the scripts used to 170 control compilation and installation of the executable. However, as a 171 special exception, the source code distributed need not include 172 anything that is normally distributed (in either source or binary 173 form) with the major components (compiler, kernel, and so on) of the 174 operating system on which the executable runs, unless that component 175 itself accompanies the executable. 176 177 If distribution of executable or object code is made by offering 178 access to copy from a designated place, then offering equivalent 179 access to copy the source code from the same place counts as 180 distribution of the source code, even though third parties are not 181 compelled to copy the source along with the object code. 182 184 4. You may not copy, modify, sublicense, or distribute the Program 185 except as expressly provided under this License. Any attempt 186 otherwise to copy, modify, sublicense or distribute the Program is 187 void, and will automatically terminate your rights under this License. 188 However, parties who have received copies, or rights, from you under 189 this License will not have their licenses terminated so long as such 190 parties remain in full compliance. 191 192 5. You are not required to accept this License, since you have not 193 signed it. However, nothing else grants you permission to modify or 194 distribute the Program or its derivative works. These actions are 195 prohibited by law if you do not accept this License. Therefore, by 196 modifying or distributing the Program (or any work based on the 197 Program), you indicate your acceptance of this License to do so, and 198 all its terms and conditions for copying, distributing or modifying 199 the Program or works based on it. 200 201 6. Each time you redistribute the Program (or any work based on the 202 Program), the recipient automatically receives a license from the 203 original licensor to copy, distribute or modify the Program subject to 204 these terms and conditions. You may not impose any further 205 restrictions on the recipients' exercise of the rights granted herein. 206 You are not responsible for enforcing compliance by third parties to 207 this License. 208 209 7. If, as a consequence of a court judgment or allegation of patent 210 infringement or for any other reason (not limited to patent issues), 211 conditions are imposed on you (whether by court order, agreement or 212 otherwise) that contradict the conditions of this License, they do not 213 excuse you from the conditions of this License. If you cannot 214 distribute so as to satisfy simultaneously your obligations under this 215 License and any other pertinent obligations, then as a consequence you 216 may not distribute the Program at all. For example, if a patent 217 license would not permit royalty-free redistribution of the Program by 218 all those who receive copies directly or indirectly through you, then 219 the only way you could satisfy both it and this License would be to 220 refrain entirely from distribution of the Program. 221 222 If any portion of this section is held invalid or unenforceable under 223 any particular circumstance, the balance of the section is intended to 224 apply and the section as a whole is intended to apply in other 225 circumstances. 226 227 It is not the purpose of this section to induce you to infringe any 228 patents or other property right claims or to contest validity of any 229 such claims; this section has the sole purpose of protecting the 230 integrity of the free software distribution system, which is 231 implemented by public license practices. Many people have made 232 generous contributions to the wide range of software distributed 233 through that system in reliance on consistent application of that 234 system; it is up to the author/donor to decide if he or she is willing 235 to distribute software through any other system and a licensee cannot 236 impose that choice. 237 238 This section is intended to make thoroughly clear what is believed to 239 be a consequence of the rest of this License. 240 242 8. If the distribution and/or use of the Program is restricted in 243 certain countries either by patents or by copyrighted interfaces, the 244 original copyright holder who places the Program under this License 245 may add an explicit geographical distribution limitation excluding 246 those countries, so that distribution is permitted only in or among 247 countries not thus excluded. In such case, this License incorporates 248 the limitation as if written in the body of this License. 249 250 9. The Free Software Foundation may publish revised and/or new versions 251 of the General Public License from time to time. Such new versions will 252 be similar in spirit to the present version, but may differ in detail to 253 address new problems or concerns. 254 255 Each version is given a distinguishing version number. If the Program 256 specifies a version number of this License which applies to it and "any 257 later version", you have the option of following the terms and conditions 258 either of that version or of any later version published by the Free 259 Software Foundation. If the Program does not specify a version number of 260 this License, you may choose any version ever published by the Free Software 261 Foundation. 262 263 10. If you wish to incorporate parts of the Program into other free 264 programs whose distribution conditions are different, write to the author 265 to ask for permission. For software which is copyrighted by the Free 266 Software Foundation, write to the Free Software Foundation; we sometimes 267 make exceptions for this. Our decision will be guided by the two goals 268 of preserving the free status of all derivatives of our free software and 269 of promoting the sharing and reuse of software generally. 270 271 NO WARRANTY 272 273 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY 274 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN 275 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES 276 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED 277 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF 278 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS 279 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE 280 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, 281 REPAIR OR CORRECTION. 282 283 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 284 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR 285 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, 286 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING 287 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED 288 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY 289 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER 290 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE 291 POSSIBILITY OF SUCH DAMAGES. 292 293 END OF TERMS AND CONDITIONS 294 296 How to Apply These Terms to Your New Programs 297 298 If you develop a new program, and you want it to be of the greatest 299 possible use to the public, the best way to achieve this is to make it 300 free software which everyone can redistribute and change under these terms. 301 302 To do so, attach the following notices to the program. It is safest 303 to attach them to the start of each source file to most effectively 304 convey the exclusion of warranty; and each file should have at least 305 the "copyright" line and a pointer to where the full notice is found. 306 307 <one line to give the program's name and a brief idea of what it does.> 308 Copyright (C) <year> <name of author> 309 310 This program is free software; you can redistribute it and/or modify 311 it under the terms of the GNU General Public License as published by 312 the Free Software Foundation; either version 2 of the License, or 313 (at your option) any later version. 314 315 This program is distributed in the hope that it will be useful, 316 but WITHOUT ANY WARRANTY; without even the implied warranty of 317 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the 318 GNU General Public License for more details. 319 320 You should have received a copy of the GNU General Public License 321 along with this program; if not, write to the Free Software 322 Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA 323 324 325 Also add information on how to contact you by electronic and paper mail. 326 327 If the program is interactive, make it output a short notice like this 328 when it starts in an interactive mode: 329 330 Gnomovision version 69, Copyright (C) year name of author 331 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. 332 This is free software, and you are welcome to redistribute it 333 under certain conditions; type `show c' for details. 334 335 The hypothetical commands `show w' and `show c' should show the appropriate 336 parts of the General Public License. Of course, the commands you use may 337 be called something other than `show w' and `show c'; they could even be 338 mouse-clicks or menu items--whatever suits your program. 339 340 You should also get your employer (if you work as a programmer) or your 341 school, if any, to sign a "copyright disclaimer" for the program, if 342 necessary. Here is a sample; alter the names: 343 344 Yoyodyne, Inc., hereby disclaims all copyright interest in the program 345 `Gnomovision' (which makes passes at compilers) written by James Hacker. 346 347 <signature of Ty Coon>, 1 April 1989 348 Ty Coon, President of Vice 349 350 This General Public License does not permit incorporating your program into 351 proprietary programs. If your program is a subroutine library, you may 352 consider it more useful to permit linking proprietary applications with the 353 library. If this is what you want to do, use the GNU Library General 354 Public License instead of this License. 355
