122 Each licensee is addressed as "you". |
| 0 | 123 |
| 124 A "library" means a collection of software functions and/or data | |
| 125 prepared so as to be conveniently linked with application programs | |
| 126 (which use some of those functions and data) to form executables. | |
| 127 | |
| 128 The "Library", below, refers to any such software library or work | |
| 129 which has been distributed under these terms. A "work based on the | |
| 130 Library" means either the Library or any derivative work under | |
| 131 copyright law: that is to say, a work containing the Library or a | |
| 132 portion of it, either verbatim or with modifications and/or translated | |
| 133 straightforwardly into another language. (Hereinafter, translation is | |
| 134 included without limitation in the term "modification".) | |
| 135 | |
| 136 "Source code" for a work means the preferred form of the work for | |
| 137 making modifications to it. For a library, complete source code means | |
| 138 all the source code for all modules it contains, plus any associated | |
| 139 interface definition files, plus the scripts used to control compilation | |
| 140 and installation of the library. | |
| 141 | |
| 142 Activities other than copying, distribution and modification are not | |
| 143 covered by this License; they are outside its scope. The act of | |
| 144 running a program using the Library is not restricted, and output from | |
| 145 such a program is covered only if its contents constitute a work based | |
| 146 on the Library (independent of the use of the Library in a tool for | |
| 147 writing it). Whether that is true depends on what the Library does | |
| 148 and what the program that uses the Library does. | |
| 149 | |
| 150 1. You may copy and distribute verbatim copies of the Library's | |
| 151 complete source code as you receive it, in any medium, provided that | |
| 152 you conspicuously and appropriately publish on each copy an | |
| 153 appropriate copyright notice and disclaimer of warranty; keep intact | |
| 154 all the notices that refer to this License and to the absence of any | |
| 155 warranty; and distribute a copy of this License along with the | |
| 156 Library. | |
| 157 | |
| 158 You may charge a fee for the physical act of transferring a copy, | |
| 159 and you may at your option offer warranty protection in exchange for a | |
| 160 fee. | |
| 161 | |
| 162 2. You may modify your copy or copies of the Library or any portion | |
| 163 of it, thus forming a work based on the Library, and copy and | |
| 164 distribute such modifications or work under the terms of Section 1 | |
| 165 above, provided that you also meet all of these conditions: | |
| 166 | |
| 167 a) The modified work must itself be a software library. | |
| 168 | |
| 169 b) You must cause the files modified to carry prominent notices | |
| 170 stating that you changed the files and the date of any change. | |
| 171 | |
| 172 c) You must cause the whole of the work to be licensed at no | |
| 173 charge to all third parties under the terms of this License. | |
| 174 | |
| 175 d) If a facility in the modified Library refers to a function or a | |
| 176 table of data to be supplied by an application program that uses | |
| 177 the facility, other than as an argument passed when the facility | |
| 178 is invoked, then you must make a good faith effort to ensure that, | |
| 179 in the event an application does not supply such function or | |
| 180 table, the facility still operates, and performs whatever part of | |
| 181 its purpose remains meaningful. | |
| 182 | |
| 183 (For example, a function in a library to compute square roots has | |
| 184 a purpose that is entirely well-defined independent of the | |
| 185 application. Therefore, Subsection 2d requires that any | |
| 186 application-supplied function or table used by this function must | |
| 187 be optional: if the application does not supply it, the square | |
| 188 root function must still compute square roots.) | |
| 189 | |
| 190 These requirements apply to the modified work as a whole. If | |
| 191 identifiable sections of that work are not derived from the Library, | |
| 192 and can be reasonably considered independent and separate works in | |
| 193 themselves, then this License, and its terms, do not apply to those | |
| 194 sections when you distribute them as separate works. But when you | |
| 195 distribute the same sections as part of a whole which is a work based | |
| 196 on the Library, the distribution of the whole must be on the terms of | |
| 197 this License, whose permissions for other licensees extend to the | |
| 198 entire whole, and thus to each and every part regardless of who wrote | |
| 199 it. | |
| 200 | |
| 201 Thus, it is not the intent of this section to claim rights or contest | |
| 202 your rights to work written entirely by you; rather, the intent is to | |
| 203 exercise the right to control the distribution of derivative or | |
| 204 collective works based on the Library. | |
| 205 | |
| 206 In addition, mere aggregation of another work not based on the Library | |
| 207 with the Library (or with a work based on the Library) on a volume of | |
| 208 a storage or distribution medium does not bring the other work under | |
| 209 the scope of this License. | |
| 210 | |
| 211 3. You may opt to apply the terms of the ordinary GNU General Public | |
| 212 License instead of this License to a given copy of the Library. To do | |
| 213 this, you must alter all the notices that refer to this License, so | |
| 214 that they refer to the ordinary GNU General Public License, version 2, | |
| 215 instead of to this License. (If a newer version than version 2 of the | |
| 216 ordinary GNU General Public License has appeared, then you can specify | |
| 217 that version instead if you wish.) Do not make any other change in | |
| 218 these notices. | |
| 219 | |
| 220 Once this change is made in a given copy, it is irreversible for | |
| 221 that copy, so the ordinary GNU General Public License applies to all | |
| 222 subsequent copies and derivative works made from that copy. | |
| 223 | |
| 224 This option is useful when you wish to copy part of the code of | |
| 225 the Library into a program that is not a library. | |
| 226 | |
| 227 4. You may copy and distribute the Library (or a portion or | |
| 228 derivative of it, under Section 2) in object code or executable form | |
| 229 under the terms of Sections 1 and 2 above provided that you accompany | |
| 230 it with the complete corresponding machine-readable source code, which | |
| 231 must be distributed under the terms of Sections 1 and 2 above on a | |
| 232 medium customarily used for software interchange. | |
| 233 | |
| 234 If distribution of object code is made by offering access to copy | |
| 235 from a designated place, then offering equivalent access to copy the | |
| 236 source code from the same place satisfies the requirement to | |
| 237 distribute the source code, even though third parties are not | |
| 238 compelled to copy the source along with the object code. | |
| 239 | |
| 240 5. A program that contains no derivative of any portion of the | |
| 241 Library, but is designed to work with the Library by being compiled or | |
| 242 linked with it, is called a "work that uses the Library". Such a | |
| 243 work, in isolation, is not a derivative work of the Library, and | |
| 244 therefore falls outside the scope of this License. | |
| 245 | |
| 246 However, linking a "work that uses the Library" with the Library | |
| 247 creates an executable that is a derivative of the Library (because it | |
| 248 contains portions of the Library), rather than a "work that uses the | |
| 249 library". The executable is therefore covered by this License. | |
| 250 Section 6 states terms for distribution of such executables. | |
| 251 | |
| 252 When a "work that uses the Library" uses material from a header file | |
| 253 that is part of the Library, the object code for the work may be a | |
| 254 derivative work of the Library even though the source code is not. | |
| 255 Whether this is true is especially significant if the work can be | |
| 256 linked without the Library, or if the work is itself a library. The | |
| 257 threshold for this to be true is not precisely defined by law. | |
| 258 | |
| 259 If such an object file uses only numerical parameters, data | |
| 260 structure layouts and accessors, and small macros and small inline | |
| 261 functions (ten lines or less in length), then the use of the object | |
| 262 file is unrestricted, regardless of whether it is legally a derivative | |
| 263 work. (Executables containing this object code plus portions of the | |
| 264 Library will still fall under Section 6.) | |
| 265 | |
| 266 Otherwise, if the work is a derivative of the Library, you may | |
| 267 distribute the object code for the work under the terms of Section 6. | |
| 268 Any executables containing that work also fall under Section 6, | |
| 269 whether or not they are linked directly with the Library itself. | |
| 270 | |

271 6. As an exception to the Sections above, you may also combine or |
| 0 | 272 link a "work that uses the Library" with the Library to produce a |
| 273 work containing portions of the Library, and distribute that work | |
| 274 under terms of your choice, provided that the terms permit | |
| 275 modification of the work for the customer's own use and reverse | |
| 276 engineering for debugging such modifications. | |
| 277 | |
| 278 You must give prominent notice with each copy of the work that the | |
| 279 Library is used in it and that the Library and its use are covered by | |
| 280 this License. You must supply a copy of this License. If the work | |
| 281 during execution displays copyright notices, you must include the | |
| 282 copyright notice for the Library among them, as well as a reference | |
| 283 directing the user to the copy of this License. Also, you must do one | |
| 284 of these things: | |
| 285 | |
| 286 a) Accompany the work with the complete corresponding | |
| 287 machine-readable source code for the Library including whatever | |
| 288 changes were used in the work (which must be distributed under | |
| 289 Sections 1 and 2 above); and, if the work is an executable linked | |
| 290 with the Library, with the complete machine-readable "work that | |
| 291 uses the Library", as object code and/or source code, so that the | |
| 292 user can modify the Library and then relink to produce a modified | |
| 293 executable containing the modified Library. (It is understood | |
| 294 that the user who changes the contents of definitions files in the | |
| 295 Library will not necessarily be able to recompile the application | |
| 296 to use the modified definitions.) | |

322 normally distributed (in either source or binary form) with the major |
| 0 | 323 components (compiler, kernel, and so on) of the operating system on |
| 324 which the executable runs, unless that component itself accompanies | |
| 325 the executable. | |
| 326 | |
| 327 It may happen that this requirement contradicts the license | |
| 328 restrictions of other proprietary libraries that do not normally | |
| 329 accompany the operating system. Such a contradiction means you cannot | |
| 330 use both them and the Library together in an executable that you | |
| 331 distribute. | |
| 332 | |
| 333 7. You may place library facilities that are a work based on the | |
| 334 Library side-by-side in a single library together with other library | |
| 335 facilities not covered by this License, and distribute such a combined | |
| 336 library, provided that the separate distribution of the work based on | |
| 337 the Library and of the other library facilities is otherwise | |
| 338 permitted, and provided that you do these two things: | |
| 339 | |
| 340 a) Accompany the combined library with a copy of the same work | |
| 341 based on the Library, uncombined with any other library | |
| 342 facilities. This must be distributed under the terms of the | |
| 343 Sections above. | |
| 344 | |
| 345 b) Give prominent notice with the combined library of the fact | |
| 346 that part of it is a work based on the Library, and explaining | |
| 347 where to find the accompanying uncombined form of the same work. | |
| 348 | |
| 349 8. You may not copy, modify, sublicense, link with, or distribute | |
| 350 the Library except as expressly provided under this License. Any | |
| 351 attempt otherwise to copy, modify, sublicense, link with, or | |
| 352 distribute the Library is void, and will automatically terminate your | |
| 353 rights under this License. However, parties who have received copies, | |
| 354 or rights, from you under this License will not have their licenses | |
| 355 terminated so long as such parties remain in full compliance. | |
| 356 | |
| 357 9. You are not required to accept this License, since you have not | |
| 358 signed it. However, nothing else grants you permission to modify or | |
| 359 distribute the Library or its derivative works. These actions are | |
| 360 prohibited by law if you do not accept this License. Therefore, by | |
| 361 modifying or distributing the Library (or any work based on the | |
| 362 Library), you indicate your acceptance of this License to do so, and | |
| 363 all its terms and conditions for copying, distributing or modifying | |
| 364 the Library or works based on it. | |
| 365 | |
| 366 10. Each time you redistribute the Library (or any work based on the | |
| 367 Library), the recipient automatically receives a license from the | |
| 368 original licensor to copy, distribute, link with or modify the Library | |
| 369 subject to these terms and conditions. You may not impose any further | |
| 370 restrictions on the recipients' exercise of the rights granted herein. | |

371 You are not responsible for enforcing compliance by third parties with |
| 0 | 372 this License. |
| 373 | |
| 374 11. If, as a consequence of a court judgment or allegation of patent | |
| 375 infringement or for any other reason (not limited to patent issues), | |
| 376 conditions are imposed on you (whether by court order, agreement or | |
| 377 otherwise) that contradict the conditions of this License, they do not | |
| 378 excuse you from the conditions of this License. If you cannot | |
| 379 distribute so as to satisfy simultaneously your obligations under this | |
| 380 License and any other pertinent obligations, then as a consequence you | |
| 381 may not distribute the Library at all. For example, if a patent | |
| 382 license would not permit royalty-free redistribution of the Library by | |
| 383 all those who receive copies directly or indirectly through you, then | |
| 384 the only way you could satisfy both it and this License would be to | |
| 385 refrain entirely from distribution of the Library. | |

| 387 If any portion of this section is held invalid or unenforceable under any | |
| 388 particular circumstance, the balance of the section is intended to apply, | |
| 389 and the section as a whole is intended to apply in other circumstances. | |
| 390 | |
| 391 It is not the purpose of this section to induce you to infringe any | |
| 392 patents or other property right claims or to contest validity of any | |
| 393 such claims; this section has the sole purpose of protecting the | |
| 394 integrity of the free software distribution system which is | |
| 395 implemented by public license practices. Many people have made | |
| 396 generous contributions to the wide range of software distributed | |
| 397 through that system in reliance on consistent application of that | |
| 398 system; it is up to the author/donor to decide if he or she is willing | |
| 399 to distribute software through any other system and a licensee cannot | |
| 400 impose that choice. | |
| 401 | |
| 402 This section is intended to make thoroughly clear what is believed to | |
| 403 be a consequence of the rest of this License. | |
| 404 | |
| 405 12. If the distribution and/or use of the Library is restricted in | |
| 406 certain countries either by patents or by copyrighted interfaces, the | |
| 407 original copyright holder who places the Library under this License may add | |
| 408 an explicit geographical distribution limitation excluding those countries, | |
| 409 so that distribution is permitted only in or among countries not thus | |
| 410 excluded. In such case, this License incorporates the limitation as if | |
| 411 written in the body of this License. | |

414 versions of the Lesser General Public License from time to time. |
| 0 | 415 Such new versions will be similar in spirit to the present version, |
| 416 but may differ in detail to address new problems or concerns. | |
| 417 | |
| 418 Each version is given a distinguishing version number. If the Library | |
| 419 specifies a version number of this License which applies to it and | |
| 420 "any later version", you have the option of following the terms and | |
| 421 conditions either of that version or of any later version published by | |
| 422 the Free Software Foundation. If the Library does not specify a | |
| 423 license version number, you may choose any version ever published by | |
| 424 the Free Software Foundation. | |
| 425 | |
| 426 14. If you wish to incorporate parts of the Library into other free | |
| 427 programs whose distribution conditions are incompatible with these, | |
| 428 write to the author to ask for permission. For software which is | |
| 429 copyrighted by the Free Software Foundation, write to the Free | |
| 430 Software Foundation; we sometimes make exceptions for this. Our | |
| 431 decision will be guided by the two goals of preserving the free status | |
| 432 of all derivatives of our free software and of promoting the sharing | |
| 433 and reuse of software generally. | |

| 435 NO WARRANTY | |
