| 9 | Everyone is permitted to copy and distribute verbatim copies |
| 10 | of this license document, but changing it is not allowed. |
| 11 | |
| 12 | Preamble |
| 13 | |
| 14 | The license agreements of most software companies try to keep users |
| 15 | at the mercy of those companies. By contrast, our General Public |
| 16 | License is intended to guarantee your freedom to share and change free |
| 17 | software--to make sure the software is free for all its users. The |
| 18 | General Public License applies to the Free Software Foundation`s |
| 19 | software and to any other program whose authors commit to using it. |
| 20 | You can use it for your programs, too. |
| 21 | |
| 22 | When we speak of free software, we are referring to freedom, not |
| 23 | price. Specifically, the General Public License is designed to make |
| 24 | sure that you have the freedom to give away or sell copies of free |
| 25 | software, that you receive source code or can get it if you want it, |
| 26 | that you can change the software or use pieces of it in new free |
| 27 | programs; and that you know you can do these things. |
| 28 | |
| 29 | To protect your rights, we need to make restrictions that forbid |
| 30 | anyone to deny you these rights or to ask you to surrender the rights. |
| 31 | These restrictions translate to certain responsibilities for you if you |
| 32 | distribute copies of the software, or if you modify it. |
| 33 | |
| 34 | For example, if you distribute copies of a such a program, whether |
| 35 | gratis or for a fee, you must give the recipients all the rights that |
| 36 | you have. You must make sure that they, too, receive or can get the |
| 37 | source code. And you must tell them their rights. |
| 38 | |
| 39 | We protect your rights with two steps: (1) copyright the software, and |
| 40 | (2) offer you this license which gives you legal permission to copy, |
| 41 | distribute and/or modify the software. |
| 42 | |
| 43 | Also, for each author`s protection and ours, we want to make certain |
| 44 | that everyone understands that there is no warranty for this free |
| 45 | software. If the software is modified by someone else and passed on, we |
| 46 | want its recipients to know that what they have is not the original, so |
| 47 | that any problems introduced by others will not reflect on the original |
| 48 | authors` reputations. |
| 49 | |
| 50 | The precise terms and conditions for copying, distribution and |
| 51 | modification follow. |
| 52 | |
| 53 | GNU GENERAL PUBLIC LICENSE |
| 54 | TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION |
| 55 | |
| 56 | 0. This License Agreement applies to any program or other work which |
| 57 | contains a notice placed by the copyright holder saying it may be |
| 58 | distributed under the terms of this General Public License. The |
| 59 | "Program", below, refers to any such program or work, and a "work based |
| 60 | on the Program" means either the Program or any work containing the |
| 61 | Program or a portion of it, either verbatim or with modifications. Each |
| 62 | licensee is addressed as "you". |
| 63 | |
| 64 | 1. You may copy and distribute verbatim copies of the Program`s source |
| 65 | code as you receive it, in any medium, provided that you conspicuously and |
| 66 | appropriately publish on each copy an appropriate copyright notice and |
| 67 | disclaimer of warranty; keep intact all the notices that refer to this |
| 68 | General Public License and to the absence of any warranty; and give any |
| 69 | other recipients of the Program a copy of this General Public License |
| 70 | along with the Program. You may charge a fee for the physical act of |
| 71 | transferring a copy. |
| 72 | |
| 73 | 2. You may modify your copy or copies of the Program or any portion of |
| 74 | it, and copy and distribute such modifications under the terms of Paragraph |
| 75 | 1 above, provided that you also do the following: |
| 76 | |
| 77 | a) cause the modified files to carry prominent notices stating that |
| 78 | you changed the files and the date of any change; and |
| 79 | |
| 80 | b) cause the whole of any work that you distribute or publish, that |
| 81 | in whole or in part contains the Program or any part thereof, either |
| 82 | with or without modifications, to be licensed at no charge to all |
| 83 | third parties under the terms of this General Public License (except |
| 84 | that you may choose to grant warranty protection to some or all |
| 85 | third parties, at your option). |
| 86 | |
| 87 | c) If the modified program normally reads commands interactively when |
| 88 | run, you must cause it, when started running for such interactive use |
| 89 | in the simplest and most usual way, to print or display an |
| 90 | announcement including an appropriate copyright notice and a notice |
| 91 | that there is no warranty (or else, saying that you provide a |
| 92 | warranty) and that users may redistribute the program under these |
| 93 | conditions, and telling the user how to view a copy of this General |
| 94 | Public License. |
| 95 | |
| 96 | d) You may charge a fee for the physical act of transferring a |
| 97 | copy, and you may at your option offer warranty protection in |
| 98 | exchange for a fee. |
| 99 | |
| 100 | Mere aggregation of another independent work with the Program (or its |
| 101 | derivative) on a volume of a storage or distribution medium does not bring |
| 102 | the other work under the scope of these terms. |
| 103 | |
| 104 | 3. You may copy and distribute the Program (or a portion or derivative of |
| 105 | it, under Paragraph 2) in object code or executable form under the terms of |
| 106 | Paragraphs 1 and 2 above provided that you also do one of the following: |
| 107 | |
| 108 | a) accompany it with the complete corresponding machine-readable |
| 109 | source code, which must be distributed under the terms of |
| 110 | Paragraphs 1 and 2 above; or, |
| 111 | |
| 112 | b) accompany it with a written offer, valid for at least three |
| 113 | years, to give any third party free (except for a nominal charge |
| 114 | for the cost of distribution) a complete machine-readable copy of the |
| 115 | corresponding source code, to be distributed under the terms of |
| 116 | Paragraphs 1 and 2 above; or, |
| 117 | |
| 118 | c) accompany it with the information you received as to where the |
| 119 | corresponding source code may be obtained. (This alternative is |
| 120 | allowed only for noncommercial distribution and only if you |
| 121 | received the program in object code or executable form alone.) |
| 122 | |
| 123 | Source code for a work means the preferred form of the work for making |
| 124 | modifications to it. For an executable file, complete source code means |
| 125 | all the source code for all modules it contains; but, as a special |
| 126 | exception, it need not include source code for modules which are standard |
| 127 | libraries that accompany the operating system on which the executable |
| 128 | file runs, or for standard header files or definitions files that |
| 129 | accompany that operating system. |
| 130 | |
| 131 | 4. You may not copy, modify, sublicense, distribute or transfer the |
| 132 | Program except as expressly provided under this General Public License. |
| 133 | Any attempt otherwise to copy, modify, sublicense, distribute or transfer |
| 134 | the Program is void, and will automatically terminate your rights to use |
| 135 | the Program under this License. However, parties who have received |
| 136 | copies, or rights to use copies, from you under this General Public |
| 137 | License will not have their licenses terminated so long as such parties |
| 138 | remain in full compliance. |
| 139 | |
| 140 | 5. By copying, distributing or modifying the Program (or any work based |
| 141 | on the Program) you indicate your acceptance of this license to do so, |
| 142 | and all its terms and conditions. |
| 143 | |
| 144 | 6. Each time you redistribute the Program (or any work based on the |
| 145 | Program), the recipient automatically receives a license from the original |
| 146 | licensor to copy, distribute or modify the Program subject to these |
| 147 | terms and conditions. You may not impose any further restrictions on the |
| 148 | recipients` exercise of the rights granted herein. |
| 149 | |
| 150 | 7. The Free Software Foundation may publish revised and/or new versions |
| 151 | of the General Public License from time to time. Such new versions will |
| 152 | be similar in spirit to the present version, but may differ in detail to |
| 153 | address new problems or concerns. |
| 154 | |
| 155 | Each version is given a distinguishing version number. If the Program |
| 156 | specifies a version number of the license which applies to it and "any |
| 157 | later version", you have the option of following the terms and conditions |
| 158 | either of that version or of any later version published by the Free |
| 159 | Software Foundation. If the Program does not specify a version number of |
| 160 | the license, you may choose any version ever published by the Free Software |
| 161 | Foundation. |
| 162 | |
| 163 | 8. If you wish to incorporate parts of the Program into other free |
| 164 | programs whose distribution conditions are different, write to the author |
| 165 | to ask for permission. For software which is copyrighted by the Free |
| 166 | Software Foundation, write to the Free Software Foundation; we sometimes |
| 167 | make exceptions for this. Our decision will be guided by the two goals |
| 168 | of preserving the free status of all derivatives of our free software and |
| 169 | of promoting the sharing and reuse of software generally. |
| 170 | |
| 171 | NO WARRANTY |
| 172 | |
| 173 | 9. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY |
| 174 | FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN |
| 175 | OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES |
| 176 | PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED |
| 177 | OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF |
| 178 | MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS |
| 179 | TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE |
| 180 | PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, |
| 181 | REPAIR OR CORRECTION. |
| 182 | |
| 183 | 10. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING |
| 184 | WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR |
| 185 | REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, |
| 186 | INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING |
| 187 | OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED |
| 188 | TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY |
| 189 | YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER |
| 190 | PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE |
| 191 | POSSIBILITY OF SUCH DAMAGES. |
| 192 | |
| 193 | END OF TERMS AND CONDITIONS |
| 194 | |
| 195 | Appendix: How to Apply These Terms to Your New Programs |
| 196 | |
| 197 | If you develop a new program, and you want it to be of the greatest |
| 198 | possible use to humanity, the best way to achieve this is to make it |
| 199 | free software which everyone can redistribute and change under these |
| 200 | terms. |
| 201 | |
| 202 | To do so, attach the following notices to the program. It is safest to |
| 203 | attach them to the start of each source file to most effectively convey |
| 204 | the exclusion of warranty; and each file should have at least the |
| 205 | "copyright" line and a pointer to where the full notice is found. |
| 206 | |
| 207 | <one line to give the program`s name and a brief idea of what it does.> |
| 208 | Copyright (C) 19yy <name of author> |
| 209 | |
| 210 | This program is free software; you can redistribute it and/or modify |
| 211 | it under the terms of the GNU General Public License as published by |
| 212 | the Free Software Foundation; either version 1, or (at your option) |
| 213 | any later version. |
| 214 | |
| 215 | This program is distributed in the hope that it will be useful, |
| 216 | but WITHOUT ANY WARRANTY; without even the implied warranty of |
| 217 | MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the |
| 218 | GNU General Public License for more details. |
| 219 | |
| 220 | You should have received a copy of the GNU General Public License |
| 221 | along with this program; if not, write to the Free Software |
| 222 | Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA. |
| 223 | |
| 224 | Also add information on how to contact you by electronic and paper mail. |
| 225 | |
| 226 | If the program is interactive, make it output a short notice like this |
| 227 | when it starts in an interactive mode: |
| 228 | |
| 229 | Gnomovision version 69, Copyright (C) 19xx name of author |
| 230 | Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w`. |
| 231 | This is free software, and you are welcome to redistribute it |
| 232 | under certain conditions; type `show c` for details. |
| 233 | |
| 234 | The hypothetical commands `show w` and `show c` should show the |
| 235 | appropriate parts of the General Public License. Of course, the |
| 236 | commands you use may be called something other than `show w` and `show |
| 237 | c`; they could even be mouse-clicks or menu items--whatever suits your |
| 238 | program. |
| 239 | |
| 240 | You should also get your employer (if you work as a programmer) or your |
| 241 | school, if any, to sign a "copyright disclaimer" for the program, if |
| 242 | necessary. Here a sample; alter the names: |
| 243 | |
| 244 | Yoyodyne, Inc., hereby disclaims all copyright interest in the |
| 245 | program `Gnomovision` (a program to direct compilers to make passes |
| 246 | at assemblers) written by James Hacker. |
| 247 | |

| 250 | |
| 251 | That`s all there is to it! |
