1 EXT2ED is hereby placed under the terms of the GNU General Public License. 2 Follows the GNU license. 3 4 Gadi Oxman, August 1995 5 6 --------------------------------------------------------------------------- 7 8 GNU GENERAL PUBLIC LICENSE 9 Version 2, June 1991 10 11 Copyright (C) 1989, 1991 Free Software Foundation, Inc. 12 675 Mass Ave, Cambridge, MA 02139, USA 13 Everyone is permitted to copy and distribute verbatim copies 14 of this license document, but changing it is not allowed. 15 16 Preamble 17 18 The licenses for most software are designed to take away your 19 freedom to share and change it. By contrast, the GNU General Public 20 License is intended to guarantee your freedom to share and change free 21 software--to make sure the software is free for all its users. This 22 General Public License applies to most of the Free Software 23 Foundation's software and to any other program whose authors commit to 24 using it. (Some other Free Software Foundation software is covered by 25 the GNU Library General Public License instead.) You can apply it to 26 your programs, too. 27 28 When we speak of free software, we are referring to freedom, not 29 price. Our General Public Licenses are designed to make sure that you 30 have the freedom to distribute copies of free software (and charge for 31 this service if you wish), that you receive source code or can get it 32 if you want it, that you can change the software or use pieces of it 33 in new free programs; and that you know you can do these things. 34 35 To protect your rights, we need to make restrictions that forbid 36 anyone to deny you these rights or to ask you to surrender the rights. 37 These restrictions translate to certain responsibilities for you if you 38 distribute copies of the software, or if you modify it. 39 40 For example, if you distribute copies of such a program, whether 41 gratis or for a fee, you must give the recipients all the rights that 42 you have. You must make sure that they, too, receive or can get the 43 source code. And you must show them these terms so they know their 44 rights. 45 46 We protect your rights with two steps: (1) copyright the software, and 47 (2) offer you this license which gives you legal permission to copy, 48 distribute and/or modify the software. 49 50 Also, for each author's protection and ours, we want to make certain 51 that everyone understands that there is no warranty for this free 52 software. If the software is modified by someone else and passed on, we 53 want its recipients to know that what they have is not the original, so 54 that any problems introduced by others will not reflect on the original 55 authors' reputations. 56 57 Finally, any free program is threatened constantly by software 58 patents. We wish to avoid the danger that redistributors of a free 59 program will individually obtain patent licenses, in effect making the 60 program proprietary. To prevent this, we have made it clear that any 61 patent must be licensed for everyone's free use or not licensed at all. 62 63 The precise terms and conditions for copying, distribution and 64 modification follow. 65 67 GNU GENERAL PUBLIC LICENSE 68 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 69 70 0. This License applies to any program or other work which contains 71 a notice placed by the copyright holder saying it may be distributed 72 under the terms of this General Public License. The "Program", below, 73 refers to any such program or work, and a "work based on the Program" 74 means either the Program or any derivative work under copyright law: 75 that is to say, a work containing the Program or a portion of it, 76 either verbatim or with modifications and/or translated into another 77 language. (Hereinafter, translation is included without limitation in 78 the term "modification".) Each licensee is addressed as "you". 79 80 Activities other than copying, distribution and modification are not 81 covered by this License; they are outside its scope. The act of 82 running the Program is not restricted, and the output from the Program 83 is covered only if its contents constitute a work based on the 84 Program (independent of having been made by running the Program). 85 Whether that is true depends on what the Program does. 86 87 1. You may copy and distribute verbatim copies of the Program's 88 source code as you receive it, in any medium, provided that you 89 conspicuously and appropriately publish on each copy an appropriate 90 copyright notice and disclaimer of warranty; keep intact all the 91 notices that refer to this License and to the absence of any warranty; 92 and give any other recipients of the Program a copy of this License 93 along with the Program. 94 95 You may charge a fee for the physical act of transferring a copy, and 96 you may at your option offer warranty protection in exchange for a fee. 97 98 2. You may modify your copy or copies of the Program or any portion 99 of it, thus forming a work based on the Program, and copy and 100 distribute such modifications or work under the terms of Section 1 101 above, provided that you also meet all of these conditions: 102 103 a) You must cause the modified files to carry prominent notices 104 stating that you changed the files and the date of any change. 105 106 b) You must cause any work that you distribute or publish, that in 107 whole or in part contains or is derived from the Program or any 108 part thereof, to be licensed as a whole at no charge to all third 109 parties under the terms of this License. 110 111 c) If the modified program normally reads commands interactively 112 when run, you must cause it, when started running for such 113 interactive use in the most ordinary way, to print or display an 114 announcement including an appropriate copyright notice and a 115 notice that there is no warranty (or else, saying that you provide 116 a warranty) and that users may redistribute the program under 117 these conditions, and telling the user how to view a copy of this 118 License. (Exception: if the Program itself is interactive but 119 does not normally print such an announcement, your work based on 120 the Program is not required to print an announcement.) 121 123 These requirements apply to the modified work as a whole. If 124 identifiable sections of that work are not derived from the Program, 125 and can be reasonably considered independent and separate works in 126 themselves, then this License, and its terms, do not apply to those 127 sections when you distribute them as separate works. But when you 128 distribute the same sections as part of a whole which is a work based 129 on the Program, the distribution of the whole must be on the terms of 130 this License, whose permissions for other licensees extend to the 131 entire whole, and thus to each and every part regardless of who wrote it. 132 133 Thus, it is not the intent of this section to claim rights or contest 134 your rights to work written entirely by you; rather, the intent is to 135 exercise the right to control the distribution of derivative or 136 collective works based on the Program. 137 138 In addition, mere aggregation of another work not based on the Program 139 with the Program (or with a work based on the Program) on a volume of 140 a storage or distribution medium does not bring the other work under 141 the scope of this License. 142 143 3. You may copy and distribute the Program (or a work based on it, 144 under Section 2) in object code or executable form under the terms of 145 Sections 1 and 2 above provided that you also do one of the following: 146 147 a) Accompany it with the complete corresponding machine-readable 148 source code, which must be distributed under the terms of Sections 149 1 and 2 above on a medium customarily used for software interchange; or, 150 151 b) Accompany it with a written offer, valid for at least three 152 years, to give any third party, for a charge no more than your 153 cost of physically performing source distribution, a complete 154 machine-readable copy of the corresponding source code, to be 155 distributed under the terms of Sections 1 and 2 above on a medium 156 customarily used for software interchange; or, 157 158 c) Accompany it with the information you received as to the offer 159 to distribute corresponding source code. (This alternative is 160 allowed only for noncommercial distribution and only if you 161 received the program in object code or executable form with such 162 an offer, in accord with Subsection b above.) 163 164 The source code for a work means the preferred form of the work for 165 making modifications to it. For an executable work, complete source 166 code means all the source code for all modules it contains, plus any 167 associated interface definition files, plus the scripts used to 168 control compilation and installation of the executable. However, as a 169 special exception, the source code distributed need not include 170 anything that is normally distributed (in either source or binary 171 form) with the major components (compiler, kernel, and so on) of the 172 operating system on which the executable runs, unless that component 173 itself accompanies the executable. 174 175 If distribution of executable or object code is made by offering 176 access to copy from a designated place, then offering equivalent 177 access to copy the source code from the same place counts as 178 distribution of the source code, even though third parties are not 179 compelled to copy the source along with the object code. 180 182 4. You may not copy, modify, sublicense, or distribute the Program 183 except as expressly provided under this License. Any attempt 184 otherwise to copy, modify, sublicense or distribute the Program is 185 void, and will automatically terminate your rights under this License. 186 However, parties who have received copies, or rights, from you under 187 this License will not have their licenses terminated so long as such 188 parties remain in full compliance. 189 190 5. You are not required to accept this License, since you have not 191 signed it. However, nothing else grants you permission to modify or 192 distribute the Program or its derivative works. These actions are 193 prohibited by law if you do not accept this License. Therefore, by 194 modifying or distributing the Program (or any work based on the 195 Program), you indicate your acceptance of this License to do so, and 196 all its terms and conditions for copying, distributing or modifying 197 the Program or works based on it. 198 199 6. Each time you redistribute the Program (or any work based on the 200 Program), the recipient automatically receives a license from the 201 original licensor to copy, distribute or modify the Program subject to 202 these terms and conditions. You may not impose any further 203 restrictions on the recipients' exercise of the rights granted herein. 204 You are not responsible for enforcing compliance by third parties to 205 this License. 206 207 7. If, as a consequence of a court judgment or allegation of patent 208 infringement or for any other reason (not limited to patent issues), 209 conditions are imposed on you (whether by court order, agreement or 210 otherwise) that contradict the conditions of this License, they do not 211 excuse you from the conditions of this License. If you cannot 212 distribute so as to satisfy simultaneously your obligations under this 213 License and any other pertinent obligations, then as a consequence you 214 may not distribute the Program at all. For example, if a patent 215 license would not permit royalty-free redistribution of the Program by 216 all those who receive copies directly or indirectly through you, then 217 the only way you could satisfy both it and this License would be to 218 refrain entirely from distribution of the Program. 219 220 If any portion of this section is held invalid or unenforceable under 221 any particular circumstance, the balance of the section is intended to 222 apply and the section as a whole is intended to apply in other 223 circumstances. 224 225 It is not the purpose of this section to induce you to infringe any 226 patents or other property right claims or to contest validity of any 227 such claims; this section has the sole purpose of protecting the 228 integrity of the free software distribution system, which is 229 implemented by public license practices. Many people have made 230 generous contributions to the wide range of software distributed 231 through that system in reliance on consistent application of that 232 system; it is up to the author/donor to decide if he or she is willing 233 to distribute software through any other system and a licensee cannot 234 impose that choice. 235 236 This section is intended to make thoroughly clear what is believed to 237 be a consequence of the rest of this License. 238 240 8. If the distribution and/or use of the Program is restricted in 241 certain countries either by patents or by copyrighted interfaces, the 242 original copyright holder who places the Program under this License 243 may add an explicit geographical distribution limitation excluding 244 those countries, so that distribution is permitted only in or among 245 countries not thus excluded. In such case, this License incorporates 246 the limitation as if written in the body of this License. 247 248 9. The Free Software Foundation may publish revised and/or new versions 249 of the General Public License from time to time. Such new versions will 250 be similar in spirit to the present version, but may differ in detail to 251 address new problems or concerns. 252 253 Each version is given a distinguishing version number. If the Program 254 specifies a version number of this License which applies to it and "any 255 later version", you have the option of following the terms and conditions 256 either of that version or of any later version published by the Free 257 Software Foundation. If the Program does not specify a version number of 258 this License, you may choose any version ever published by the Free Software 259 Foundation. 260 261 10. If you wish to incorporate parts of the Program into other free 262 programs whose distribution conditions are different, write to the author 263 to ask for permission. For software which is copyrighted by the Free 264 Software Foundation, write to the Free Software Foundation; we sometimes 265 make exceptions for this. Our decision will be guided by the two goals 266 of preserving the free status of all derivatives of our free software and 267 of promoting the sharing and reuse of software generally. 268 269 NO WARRANTY 270 271 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY 272 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN 273 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES 274 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED 275 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF 276 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS 277 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE 278 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, 279 REPAIR OR CORRECTION. 280 281 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 282 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR 283 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, 284 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING 285 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED 286 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY 287 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER 288 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE 289 POSSIBILITY OF SUCH DAMAGES. 290 291 END OF TERMS AND CONDITIONS 292 294 Appendix: How to Apply These Terms to Your New Programs 295 296 If you develop a new program, and you want it to be of the greatest 297 possible use to the public, the best way to achieve this is to make it 298 free software which everyone can redistribute and change under these terms. 299 300 To do so, attach the following notices to the program. It is safest 301 to attach them to the start of each source file to most effectively 302 convey the exclusion of warranty; and each file should have at least 303 the "copyright" line and a pointer to where the full notice is found. 304 305 <one line to give the program's name and a brief idea of what it does.> 306 Copyright (C) 19yy <name of author> 307 308 This program is free software; you can redistribute it and/or modify 309 it under the terms of the GNU General Public License as published by 310 the Free Software Foundation; either version 2 of the License, or 311 (at your option) any later version. 312 313 This program is distributed in the hope that it will be useful, 314 but WITHOUT ANY WARRANTY; without even the implied warranty of 315 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the 316 GNU General Public License for more details. 317 318 You should have received a copy of the GNU General Public License 319 along with this program; if not, write to the Free Software 320 Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA. 321 322 Also add information on how to contact you by electronic and paper mail. 323 324 If the program is interactive, make it output a short notice like this 325 when it starts in an interactive mode: 326 327 Gnomovision version 69, Copyright (C) 19yy name of author 328 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. 329 This is free software, and you are welcome to redistribute it 330 under certain conditions; type `show c' for details. 331 332 The hypothetical commands `show w' and `show c' should show the appropriate 333 parts of the General Public License. Of course, the commands you use may 334 be called something other than `show w' and `show c'; they could even be 335 mouse-clicks or menu items--whatever suits your program. 336 337 You should also get your employer (if you work as a programmer) or your 338 school, if any, to sign a "copyright disclaimer" for the program, if 339 necessary. Here is a sample; alter the names: 340 341 Yoyodyne, Inc., hereby disclaims all copyright interest in the program 342 `Gnomovision' (which makes passes at compilers) written by James Hacker. 343 344 <signature of Ty Coon>, 1 April 1989 345 Ty Coon, President of Vice 346 347 This General Public License does not permit incorporating your program into 348 proprietary programs. If your program is a subroutine library, you may 349 consider it more useful to permit linking proprietary applications with the 350 library. If this is what you want to do, use the GNU Library General 351 Public License instead of this License. 352
