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

| 341 | ++This General Public License does not permit incorporating your program into |
| 342 | ++proprietary programs. If your program is a subroutine library, you may |
| 343 | ++consider it more useful to permit linking proprietary applications with the |
| 344 | ++library. If this is what you want to do, use the GNU Lesser General |
| 345 | ++Public License instead of this License. |
