| 31 | \subsection*{Preamble} |
| 32 | The licenses for most software are designed to take away your freedom to |
| 33 | share and change it. By contrast, the GNU General Public License is |
| 34 | intended to guarantee your freedom to share and change free software---to |
| 35 | make sure the software is free for all its users. This General Public |
| 36 | License applies to most of the Free Software Foundation's software and to |
| 37 | any other program whose authors commit to using it. (Some other Free |
| 38 | Software Foundation software is covered by the GNU Library General Public |
| 39 | License instead.) You can apply it to your programs, too. |
| 40 | |
| 41 | When we speak of free software, we are referring to freedom, not price. |
| 42 | Our General Public Licenses are designed to make sure that you have the |
| 43 | freedom to distribute copies of free software (and charge for this service |
| 44 | if you wish), that you receive source code or can get it if you want it, |
| 45 | that you can change the software or use pieces of it in new free programs; |
| 46 | and that you know you can do these things. |
| 47 | |
| 48 | To protect your rights, we need to make restrictions that forbid anyone to |
| 49 | deny you these rights or to ask you to surrender the rights. These |
| 50 | restrictions translate to certain responsibilities for you if you |
| 51 | distribute copies of the software, or if you modify it. |
| 52 | |
| 53 | For example, if you distribute copies of such a program, whether gratis or |
| 54 | for a fee, you must give the recipients all the rights that you have. You |
| 55 | must make sure that they, too, receive or can get the source code. And |
| 56 | you must show them these terms so they know their rights. |
| 57 | |
| 58 | We protect your rights with two steps: (1) copyright the software, and (2) |
| 59 | offer you this license which gives you legal permission to copy, |
| 60 | distribute and/or modify the software. |
| 61 | |
| 62 | Also, for each author's protection and ours, we want to make certain that |
| 63 | everyone understands that there is no warranty for this free software. If |
| 64 | the software is modified by someone else and passed on, we want its |
| 65 | recipients to know that what they have is not the original, so that any |
| 66 | problems introduced by others will not reflect on the original authors' |
| 67 | reputations. |
| 68 | |
| 69 | Finally, any free program is threatened constantly by software patents. |
| 70 | We wish to avoid the danger that redistributors of a free program will |
| 71 | individually obtain patent licenses, in effect making the program |
| 72 | proprietary. To prevent this, we have made it clear that any patent must |
| 73 | be licensed for everyone's free use or not licensed at all. |
| 74 | |
| 75 | The precise terms and conditions for copying, distribution and |
| 76 | modification follow. |

| 82 | |
| 83 | |
| 84 | \begin{enumerate} |
| 85 | |
| 86 | \addtocounter{enumi}{-1} |
| 87 | |
| 88 | \item |
| 89 | |
| 90 | This License applies to any program or other work which contains a notice |
| 91 | placed by the copyright holder saying it may be distributed under the |
| 92 | terms of this General Public License. The ``Program'', below, refers to |
| 93 | any such program or work, and a ``work based on the Program'' means either |
| 94 | the Program or any derivative work under copyright law: that is to say, a |
| 95 | work containing the Program or a portion of it, either verbatim or with |
| 96 | modifications and/or translated into another language. (Hereinafter, |
| 97 | translation is included without limitation in the term ``modification''.) |
| 98 | Each licensee is addressed as ``you''. |
| 99 | |
| 100 | Activities other than copying, distribution and modification are not |
| 101 | covered by this License; they are outside its scope. The act of |
| 102 | running the Program is not restricted, and the output from the Program |
| 103 | is covered only if its contents constitute a work based on the |
| 104 | Program (independent of having been made by running the Program). |
| 105 | Whether that is true depends on what the Program does. |
| 106 | |
| 107 | \item You may copy and distribute verbatim copies of the Program's source |
| 108 | code as you receive it, in any medium, provided that you conspicuously |
| 109 | and appropriately publish on each copy an appropriate copyright notice |
| 110 | and disclaimer of warranty; keep intact all the notices that refer to |
| 111 | this License and to the absence of any warranty; and give any other |
| 112 | recipients of the Program a copy of this License along with the Program. |
| 113 | |
| 114 | You may charge a fee for the physical act of transferring a copy, and you |
| 115 | may at your option offer warranty protection in exchange for a fee. |
| 116 | |
| 117 | \item |
| 118 | |
| 119 | You may modify your copy or copies of the Program or any portion |
| 120 | of it, thus forming a work based on the Program, and copy and |
| 121 | distribute such modifications or work under the terms of Section 1 |
| 122 | above, provided that you also meet all of these conditions: |
| 123 | |
| 124 | \begin{enumerate} |
| 125 | |
| 126 | \item |
| 127 | |
| 128 | You must cause the modified files to carry prominent notices stating that |
| 129 | you changed the files and the date of any change. |
| 130 | |
| 131 | \item |
| 132 | |
| 133 | You must cause any work that you distribute or publish, that in |
| 134 | whole or in part contains or is derived from the Program or any |
| 135 | part thereof, to be licensed as a whole at no charge to all third |
| 136 | parties under the terms of this License. |
| 137 | |
| 138 | \item |
| 139 | If the modified program normally reads commands interactively |
| 140 | when run, you must cause it, when started running for such |
| 141 | interactive use in the most ordinary way, to print or display an |
| 142 | announcement including an appropriate copyright notice and a |
| 143 | notice that there is no warranty (or else, saying that you provide |
| 144 | a warranty) and that users may redistribute the program under |
| 145 | these conditions, and telling the user how to view a copy of this |
| 146 | License. (Exception: if the Program itself is interactive but |
| 147 | does not normally print such an announcement, your work based on |
| 148 | the Program is not required to print an announcement.) |
| 149 | |
| 150 | \end{enumerate} |
| 151 | |
| 152 | |
| 153 | These requirements apply to the modified work as a whole. If |
| 154 | identifiable sections of that work are not derived from the Program, |
| 155 | and can be reasonably considered independent and separate works in |
| 156 | themselves, then this License, and its terms, do not apply to those |
| 157 | sections when you distribute them as separate works. But when you |
| 158 | distribute the same sections as part of a whole which is a work based |
| 159 | on the Program, the distribution of the whole must be on the terms of |
| 160 | this License, whose permissions for other licensees extend to the |
| 161 | entire whole, and thus to each and every part regardless of who wrote it. |
| 162 | |
| 163 | Thus, it is not the intent of this section to claim rights or contest |
| 164 | your rights to work written entirely by you; rather, the intent is to |
| 165 | exercise the right to control the distribution of derivative or |
| 166 | collective works based on the Program. |
| 167 | |
| 168 | In addition, mere aggregation of another work not based on the Program |
| 169 | with the Program (or with a work based on the Program) on a volume of |
| 170 | a storage or distribution medium does not bring the other work under |
| 171 | the scope of this License. |
| 172 | |
| 173 | \item |
| 174 | You may copy and distribute the Program (or a work based on it, |
| 175 | under Section 2) in object code or executable form under the terms of |
| 176 | Sections 1 and 2 above provided that you also do one of the following: |
| 177 | |
| 178 | \begin{enumerate} |
| 179 | |
| 180 | \item |
| 181 | |
| 182 | Accompany it with the complete corresponding machine-readable |
| 183 | source code, which must be distributed under the terms of Sections |
| 184 | 1 and 2 above on a medium customarily used for software interchange; or, |
| 185 | |
| 186 | \item |
| 187 | |
| 188 | Accompany it with a written offer, valid for at least three |
| 189 | years, to give any third party, for a charge no more than your |
| 190 | cost of physically performing source distribution, a complete |
| 191 | machine-readable copy of the corresponding source code, to be |
| 192 | distributed under the terms of Sections 1 and 2 above on a medium |
| 193 | customarily used for software interchange; or, |
| 194 | |
| 195 | \item |
| 196 | |
| 197 | Accompany it with the information you received as to the offer |
| 198 | to distribute corresponding source code. (This alternative is |
| 199 | allowed only for noncommercial distribution and only if you |
| 200 | received the program in object code or executable form with such |
| 201 | an offer, in accord with Subsection b above.) |
| 202 | |
| 203 | \end{enumerate} |
| 204 | |
| 205 | |
| 206 | The source code for a work means the preferred form of the work for |
| 207 | making modifications to it. For an executable work, complete source |
| 208 | code means all the source code for all modules it contains, plus any |
| 209 | associated interface definition files, plus the scripts used to |
| 210 | control compilation and installation of the executable. However, as a |
| 211 | special exception, the source code distributed need not include |
| 212 | anything that is normally distributed (in either source or binary |
| 213 | form) with the major components (compiler, kernel, and so on) of the |
| 214 | operating system on which the executable runs, unless that component |
| 215 | itself accompanies the executable. |
| 216 | |
| 217 | If distribution of executable or object code is made by offering |
| 218 | access to copy from a designated place, then offering equivalent |
| 219 | access to copy the source code from the same place counts as |
| 220 | distribution of the source code, even though third parties are not |
| 221 | compelled to copy the source along with the object code. |
| 222 | |
| 223 | \item |
| 224 | You may not copy, modify, sublicense, or distribute the Program |
| 225 | except as expressly provided under this License. Any attempt |
| 226 | otherwise to copy, modify, sublicense or distribute the Program is |
| 227 | void, and will automatically terminate your rights under this License. |
| 228 | However, parties who have received copies, or rights, from you under |
| 229 | this License will not have their licenses terminated so long as such |
| 230 | parties remain in full compliance. |
| 231 | |
| 232 | \item |
| 233 | You are not required to accept this License, since you have not |
| 234 | signed it. However, nothing else grants you permission to modify or |
| 235 | distribute the Program or its derivative works. These actions are |
| 236 | prohibited by law if you do not accept this License. Therefore, by |
| 237 | modifying or distributing the Program (or any work based on the |
| 238 | Program), you indicate your acceptance of this License to do so, and |
| 239 | all its terms and conditions for copying, distributing or modifying |
| 240 | the Program or works based on it. |
| 241 | |
| 242 | \item |
| 243 | Each time you redistribute the Program (or any work based on the |
| 244 | Program), the recipient automatically receives a license from the |
| 245 | original licensor to copy, distribute or modify the Program subject to |
| 246 | these terms and conditions. You may not impose any further |
| 247 | restrictions on the recipients' exercise of the rights granted herein. |
| 248 | You are not responsible for enforcing compliance by third parties to |
| 249 | this License. |
| 250 | |
| 251 | \item |
| 252 | If, as a consequence of a court judgment or allegation of patent |
| 253 | infringement or for any other reason (not limited to patent issues), |
| 254 | conditions are imposed on you (whether by court order, agreement or |
| 255 | otherwise) that contradict the conditions of this License, they do not |
| 256 | excuse you from the conditions of this License. If you cannot |
| 257 | distribute so as to satisfy simultaneously your obligations under this |
| 258 | License and any other pertinent obligations, then as a consequence you |
| 259 | may not distribute the Program at all. For example, if a patent |
| 260 | license would not permit royalty-free redistribution of the Program by |
| 261 | all those who receive copies directly or indirectly through you, then |
| 262 | the only way you could satisfy both it and this License would be to |
| 263 | refrain entirely from distribution of the Program. |
| 264 | |
| 265 | If any portion of this section is held invalid or unenforceable under |
| 266 | any particular circumstance, the balance of the section is intended to |
| 267 | apply and the section as a whole is intended to apply in other |
| 268 | circumstances. |
| 269 | |
| 270 | It is not the purpose of this section to induce you to infringe any |
| 271 | patents or other property right claims or to contest validity of any |
| 272 | such claims; this section has the sole purpose of protecting the |
| 273 | integrity of the free software distribution system, which is |
| 274 | implemented by public license practices. Many people have made |
| 275 | generous contributions to the wide range of software distributed |
| 276 | through that system in reliance on consistent application of that |
| 277 | system; it is up to the author/donor to decide if he or she is willing |
| 278 | to distribute software through any other system and a licensee cannot |
| 279 | impose that choice. |
| 280 | |
| 281 | This section is intended to make thoroughly clear what is believed to |
| 282 | be a consequence of the rest of this License. |
| 283 | |
| 284 | \item |
| 285 | If the distribution and/or use of the Program is restricted in |
| 286 | certain countries either by patents or by copyrighted interfaces, the |
| 287 | original copyright holder who places the Program under this License |
| 288 | may add an explicit geographical distribution limitation excluding |
| 289 | those countries, so that distribution is permitted only in or among |
| 290 | countries not thus excluded. In such case, this License incorporates |
| 291 | the limitation as if written in the body of this License. |
| 292 | |
| 293 | \item |
| 294 | The Free Software Foundation may publish revised and/or new versions |
| 295 | of the General Public License from time to time. Such new versions will |
| 296 | be similar in spirit to the present version, but may differ in detail to |
| 297 | address new problems or concerns. |
| 298 | |
| 299 | Each version is given a distinguishing version number. If the Program |
| 300 | specifies a version number of this License which applies to it and ``any |
| 301 | later version'', you have the option of following the terms and conditions |
| 302 | either of that version or of any later version published by the Free |
| 303 | Software Foundation. If the Program does not specify a version number of |
| 304 | this License, you may choose any version ever published by the Free Software |
| 305 | Foundation. |
| 306 | |
| 307 | \item |
| 308 | If you wish to incorporate parts of the Program into other free |
| 309 | programs whose distribution conditions are different, write to the author |
| 310 | to ask for permission. For software which is copyrighted by the Free |
| 311 | Software Foundation, write to the Free Software Foundation; we sometimes |
| 312 | make exceptions for this. Our decision will be guided by the two goals |
| 313 | of preserving the free status of all derivatives of our free software and |
| 314 | of promoting the sharing and reuse of software generally. |

| 327 | or implied, including, but not limited to, the implied warranties of |
| 328 | merchantability and fitness for a particular purpose. The entire risk as |
| 329 | to the quality and performance of the program is with you. Should the |

| 338 | out of the use or inability to use the program (including but not limited |

| 340 | you or third parties or a failure of the program to operate with any other |

| 354 | \section*{Appendix: How to Apply These Terms to Your New Programs} |
| 355 | |
| 356 | If you develop a new program, and you want it to be of the greatest |
| 357 | possible use to the public, the best way to achieve this is to make it |
| 358 | free software which everyone can redistribute and change under these |
| 359 | terms. |
| 360 | |
| 361 | To do so, attach the following notices to the program. It is safest to |
| 362 | attach them to the start of each source file to most effectively convey |
| 363 | the exclusion of warranty; and each file should have at least the |
| 364 | ``copyright'' line and a pointer to where the full notice is found. |
| 365 | |
| 366 | \begin{quote} |
| 367 | {\textless}one line to give the program's name and a brief idea of what it |
| 368 | does.{\textgreater} \\ |
| 369 | Copyright (C) {\textless}year{\textgreater} {\textless}name of |
| 370 | author{\textgreater} \\ |
| 371 | |
| 372 | This program is free software; you can redistribute it and/or modify |
| 373 | it under the terms of the GNU General Public License as published by |
| 374 | the Free Software Foundation; either version 2 of the License, or |
| 375 | (at your option) any later version. |
| 376 | |
| 377 | This program is distributed in the hope that it will be useful, |
| 378 | but WITHOUT ANY WARRANTY; without even the implied warranty of |
| 379 | MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the |
| 380 | GNU General Public License for more details. |
| 381 | |
| 382 | You should have received a copy of the GNU General Public License |
| 383 | along with this program; if not, write to the Free Software |
| 384 | Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA |
| 385 | \end{quote} |
| 386 | |
| 387 | Also add information on how to contact you by electronic and paper mail. |
| 388 | |
| 389 | If the program is interactive, make it output a short notice like this |
| 390 | when it starts in an interactive mode: |
| 391 | |
| 392 | \begin{quote} |
| 393 | Gnomovision version 69, Copyright (C) {\textless}year{\textgreater} |
| 394 | {\textless}name of author{\textgreater} \\ |
| 395 | Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. \\ |
| 396 | This is free software, and you are welcome to redistribute it |
| 397 | under certain conditions; type `show c' for details. |
| 398 | \end{quote} |
| 399 | |
| 400 | |
| 401 | The hypothetical commands {\tt show w} and {\tt show c} should show the |
| 402 | appropriate parts of the General Public License. Of course, the commands |
| 403 | you use may be called something other than {\tt show w} and {\tt show c}; |
| 404 | they could even be mouse-clicks or menu items---whatever suits your |
| 405 | program. |
| 406 | |
| 407 | You should also get your employer (if you work as a programmer) or your |
| 408 | school, if any, to sign a ``copyright disclaimer'' for the program, if |
| 409 | necessary. Here is a sample; alter the names: |
| 410 | |
| 411 | \begin{quote} |
| 412 | Yoyodyne, Inc., hereby disclaims all copyright interest in the program \\ |
| 413 | `Gnomovision' (which makes passes at compilers) written by James Hacker. \\ |

| 415 | {\textless}signature of Ty Coon{\textgreater}, 1 April 1989 \\ |
| 416 | Ty Coon, President of Vice |
| 417 | \end{quote} |
| 418 | |
| 419 | |
| 420 | This General Public License does not permit incorporating your program |
| 421 | into proprietary programs. If your program is a subroutine library, you |
| 422 | may consider it more useful to permit linking proprietary applications |
| 423 | with the library. If this is what you want to do, use the GNU Library |
| 424 | General Public License instead of this License. |
