nuclear@16 1 GNU GENERAL PUBLIC LICENSE
nuclear@16 2 Version 3, 29 June 2007
nuclear@16 3
nuclear@16 4 Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
nuclear@16 5 Everyone is permitted to copy and distribute verbatim copies
nuclear@16 6 of this license document, but changing it is not allowed.
nuclear@16 7
nuclear@16 8 Preamble
nuclear@16 9
nuclear@16 10 The GNU General Public License is a free, copyleft license for
nuclear@16 11 software and other kinds of works.
nuclear@16 12
nuclear@16 13 The licenses for most software and other practical works are designed
nuclear@16 14 to take away your freedom to share and change the works. By contrast,
nuclear@16 15 the GNU General Public License is intended to guarantee your freedom to
nuclear@16 16 share and change all versions of a program--to make sure it remains free
nuclear@16 17 software for all its users. We, the Free Software Foundation, use the
nuclear@16 18 GNU General Public License for most of our software; it applies also to
nuclear@16 19 any other work released this way by its authors. You can apply it to
nuclear@16 20 your programs, too.
nuclear@16 21
nuclear@16 22 When we speak of free software, we are referring to freedom, not
nuclear@16 23 price. Our General Public Licenses are designed to make sure that you
nuclear@16 24 have the freedom to distribute copies of free software (and charge for
nuclear@16 25 them if you wish), that you receive source code or can get it if you
nuclear@16 26 want it, that you can change the software or use pieces of it in new
nuclear@16 27 free programs, and that you know you can do these things.
nuclear@16 28
nuclear@16 29 To protect your rights, we need to prevent others from denying you
nuclear@16 30 these rights or asking you to surrender the rights. Therefore, you have
nuclear@16 31 certain responsibilities if you distribute copies of the software, or if
nuclear@16 32 you modify it: responsibilities to respect the freedom of others.
nuclear@16 33
nuclear@16 34 For example, if you distribute copies of such a program, whether
nuclear@16 35 gratis or for a fee, you must pass on to the recipients the same
nuclear@16 36 freedoms that you received. You must make sure that they, too, receive
nuclear@16 37 or can get the source code. And you must show them these terms so they
nuclear@16 38 know their rights.
nuclear@16 39
nuclear@16 40 Developers that use the GNU GPL protect your rights with two steps:
nuclear@16 41 (1) assert copyright on the software, and (2) offer you this License
nuclear@16 42 giving you legal permission to copy, distribute and/or modify it.
nuclear@16 43
nuclear@16 44 For the developers' and authors' protection, the GPL clearly explains
nuclear@16 45 that there is no warranty for this free software. For both users' and
nuclear@16 46 authors' sake, the GPL requires that modified versions be marked as
nuclear@16 47 changed, so that their problems will not be attributed erroneously to
nuclear@16 48 authors of previous versions.
nuclear@16 49
nuclear@16 50 Some devices are designed to deny users access to install or run
nuclear@16 51 modified versions of the software inside them, although the manufacturer
nuclear@16 52 can do so. This is fundamentally incompatible with the aim of
nuclear@16 53 protecting users' freedom to change the software. The systematic
nuclear@16 54 pattern of such abuse occurs in the area of products for individuals to
nuclear@16 55 use, which is precisely where it is most unacceptable. Therefore, we
nuclear@16 56 have designed this version of the GPL to prohibit the practice for those
nuclear@16 57 products. If such problems arise substantially in other domains, we
nuclear@16 58 stand ready to extend this provision to those domains in future versions
nuclear@16 59 of the GPL, as needed to protect the freedom of users.
nuclear@16 60
nuclear@16 61 Finally, every program is threatened constantly by software patents.
nuclear@16 62 States should not allow patents to restrict development and use of
nuclear@16 63 software on general-purpose computers, but in those that do, we wish to
nuclear@16 64 avoid the special danger that patents applied to a free program could
nuclear@16 65 make it effectively proprietary. To prevent this, the GPL assures that
nuclear@16 66 patents cannot be used to render the program non-free.
nuclear@16 67
nuclear@16 68 The precise terms and conditions for copying, distribution and
nuclear@16 69 modification follow.
nuclear@16 70
nuclear@16 71 TERMS AND CONDITIONS
nuclear@16 72
nuclear@16 73 0. Definitions.
nuclear@16 74
nuclear@16 75 "This License" refers to version 3 of the GNU General Public License.
nuclear@16 76
nuclear@16 77 "Copyright" also means copyright-like laws that apply to other kinds of
nuclear@16 78 works, such as semiconductor masks.
nuclear@16 79
nuclear@16 80 "The Program" refers to any copyrightable work licensed under this
nuclear@16 81 License. Each licensee is addressed as "you". "Licensees" and
nuclear@16 82 "recipients" may be individuals or organizations.
nuclear@16 83
nuclear@16 84 To "modify" a work means to copy from or adapt all or part of the work
nuclear@16 85 in a fashion requiring copyright permission, other than the making of an
nuclear@16 86 exact copy. The resulting work is called a "modified version" of the
nuclear@16 87 earlier work or a work "based on" the earlier work.
nuclear@16 88
nuclear@16 89 A "covered work" means either the unmodified Program or a work based
nuclear@16 90 on the Program.
nuclear@16 91
nuclear@16 92 To "propagate" a work means to do anything with it that, without
nuclear@16 93 permission, would make you directly or secondarily liable for
nuclear@16 94 infringement under applicable copyright law, except executing it on a
nuclear@16 95 computer or modifying a private copy. Propagation includes copying,
nuclear@16 96 distribution (with or without modification), making available to the
nuclear@16 97 public, and in some countries other activities as well.
nuclear@16 98
nuclear@16 99 To "convey" a work means any kind of propagation that enables other
nuclear@16 100 parties to make or receive copies. Mere interaction with a user through
nuclear@16 101 a computer network, with no transfer of a copy, is not conveying.
nuclear@16 102
nuclear@16 103 An interactive user interface displays "Appropriate Legal Notices"
nuclear@16 104 to the extent that it includes a convenient and prominently visible
nuclear@16 105 feature that (1) displays an appropriate copyright notice, and (2)
nuclear@16 106 tells the user that there is no warranty for the work (except to the
nuclear@16 107 extent that warranties are provided), that licensees may convey the
nuclear@16 108 work under this License, and how to view a copy of this License. If
nuclear@16 109 the interface presents a list of user commands or options, such as a
nuclear@16 110 menu, a prominent item in the list meets this criterion.
nuclear@16 111
nuclear@16 112 1. Source Code.
nuclear@16 113
nuclear@16 114 The "source code" for a work means the preferred form of the work
nuclear@16 115 for making modifications to it. "Object code" means any non-source
nuclear@16 116 form of a work.
nuclear@16 117
nuclear@16 118 A "Standard Interface" means an interface that either is an official
nuclear@16 119 standard defined by a recognized standards body, or, in the case of
nuclear@16 120 interfaces specified for a particular programming language, one that
nuclear@16 121 is widely used among developers working in that language.
nuclear@16 122
nuclear@16 123 The "System Libraries" of an executable work include anything, other
nuclear@16 124 than the work as a whole, that (a) is included in the normal form of
nuclear@16 125 packaging a Major Component, but which is not part of that Major
nuclear@16 126 Component, and (b) serves only to enable use of the work with that
nuclear@16 127 Major Component, or to implement a Standard Interface for which an
nuclear@16 128 implementation is available to the public in source code form. A
nuclear@16 129 "Major Component", in this context, means a major essential component
nuclear@16 130 (kernel, window system, and so on) of the specific operating system
nuclear@16 131 (if any) on which the executable work runs, or a compiler used to
nuclear@16 132 produce the work, or an object code interpreter used to run it.
nuclear@16 133
nuclear@16 134 The "Corresponding Source" for a work in object code form means all
nuclear@16 135 the source code needed to generate, install, and (for an executable
nuclear@16 136 work) run the object code and to modify the work, including scripts to
nuclear@16 137 control those activities. However, it does not include the work's
nuclear@16 138 System Libraries, or general-purpose tools or generally available free
nuclear@16 139 programs which are used unmodified in performing those activities but
nuclear@16 140 which are not part of the work. For example, Corresponding Source
nuclear@16 141 includes interface definition files associated with source files for
nuclear@16 142 the work, and the source code for shared libraries and dynamically
nuclear@16 143 linked subprograms that the work is specifically designed to require,
nuclear@16 144 such as by intimate data communication or control flow between those
nuclear@16 145 subprograms and other parts of the work.
nuclear@16 146
nuclear@16 147 The Corresponding Source need not include anything that users
nuclear@16 148 can regenerate automatically from other parts of the Corresponding
nuclear@16 149 Source.
nuclear@16 150
nuclear@16 151 The Corresponding Source for a work in source code form is that
nuclear@16 152 same work.
nuclear@16 153
nuclear@16 154 2. Basic Permissions.
nuclear@16 155
nuclear@16 156 All rights granted under this License are granted for the term of
nuclear@16 157 copyright on the Program, and are irrevocable provided the stated
nuclear@16 158 conditions are met. This License explicitly affirms your unlimited
nuclear@16 159 permission to run the unmodified Program. The output from running a
nuclear@16 160 covered work is covered by this License only if the output, given its
nuclear@16 161 content, constitutes a covered work. This License acknowledges your
nuclear@16 162 rights of fair use or other equivalent, as provided by copyright law.
nuclear@16 163
nuclear@16 164 You may make, run and propagate covered works that you do not
nuclear@16 165 convey, without conditions so long as your license otherwise remains
nuclear@16 166 in force. You may convey covered works to others for the sole purpose
nuclear@16 167 of having them make modifications exclusively for you, or provide you
nuclear@16 168 with facilities for running those works, provided that you comply with
nuclear@16 169 the terms of this License in conveying all material for which you do
nuclear@16 170 not control copyright. Those thus making or running the covered works
nuclear@16 171 for you must do so exclusively on your behalf, under your direction
nuclear@16 172 and control, on terms that prohibit them from making any copies of
nuclear@16 173 your copyrighted material outside their relationship with you.
nuclear@16 174
nuclear@16 175 Conveying under any other circumstances is permitted solely under
nuclear@16 176 the conditions stated below. Sublicensing is not allowed; section 10
nuclear@16 177 makes it unnecessary.
nuclear@16 178
nuclear@16 179 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
nuclear@16 180
nuclear@16 181 No covered work shall be deemed part of an effective technological
nuclear@16 182 measure under any applicable law fulfilling obligations under article
nuclear@16 183 11 of the WIPO copyright treaty adopted on 20 December 1996, or
nuclear@16 184 similar laws prohibiting or restricting circumvention of such
nuclear@16 185 measures.
nuclear@16 186
nuclear@16 187 When you convey a covered work, you waive any legal power to forbid
nuclear@16 188 circumvention of technological measures to the extent such circumvention
nuclear@16 189 is effected by exercising rights under this License with respect to
nuclear@16 190 the covered work, and you disclaim any intention to limit operation or
nuclear@16 191 modification of the work as a means of enforcing, against the work's
nuclear@16 192 users, your or third parties' legal rights to forbid circumvention of
nuclear@16 193 technological measures.
nuclear@16 194
nuclear@16 195 4. Conveying Verbatim Copies.
nuclear@16 196
nuclear@16 197 You may convey verbatim copies of the Program's source code as you
nuclear@16 198 receive it, in any medium, provided that you conspicuously and
nuclear@16 199 appropriately publish on each copy an appropriate copyright notice;
nuclear@16 200 keep intact all notices stating that this License and any
nuclear@16 201 non-permissive terms added in accord with section 7 apply to the code;
nuclear@16 202 keep intact all notices of the absence of any warranty; and give all
nuclear@16 203 recipients a copy of this License along with the Program.
nuclear@16 204
nuclear@16 205 You may charge any price or no price for each copy that you convey,
nuclear@16 206 and you may offer support or warranty protection for a fee.
nuclear@16 207
nuclear@16 208 5. Conveying Modified Source Versions.
nuclear@16 209
nuclear@16 210 You may convey a work based on the Program, or the modifications to
nuclear@16 211 produce it from the Program, in the form of source code under the
nuclear@16 212 terms of section 4, provided that you also meet all of these conditions:
nuclear@16 213
nuclear@16 214 a) The work must carry prominent notices stating that you modified
nuclear@16 215 it, and giving a relevant date.
nuclear@16 216
nuclear@16 217 b) The work must carry prominent notices stating that it is
nuclear@16 218 released under this License and any conditions added under section
nuclear@16 219 7. This requirement modifies the requirement in section 4 to
nuclear@16 220 "keep intact all notices".
nuclear@16 221
nuclear@16 222 c) You must license the entire work, as a whole, under this
nuclear@16 223 License to anyone who comes into possession of a copy. This
nuclear@16 224 License will therefore apply, along with any applicable section 7
nuclear@16 225 additional terms, to the whole of the work, and all its parts,
nuclear@16 226 regardless of how they are packaged. This License gives no
nuclear@16 227 permission to license the work in any other way, but it does not
nuclear@16 228 invalidate such permission if you have separately received it.
nuclear@16 229
nuclear@16 230 d) If the work has interactive user interfaces, each must display
nuclear@16 231 Appropriate Legal Notices; however, if the Program has interactive
nuclear@16 232 interfaces that do not display Appropriate Legal Notices, your
nuclear@16 233 work need not make them do so.
nuclear@16 234
nuclear@16 235 A compilation of a covered work with other separate and independent
nuclear@16 236 works, which are not by their nature extensions of the covered work,
nuclear@16 237 and which are not combined with it such as to form a larger program,
nuclear@16 238 in or on a volume of a storage or distribution medium, is called an
nuclear@16 239 "aggregate" if the compilation and its resulting copyright are not
nuclear@16 240 used to limit the access or legal rights of the compilation's users
nuclear@16 241 beyond what the individual works permit. Inclusion of a covered work
nuclear@16 242 in an aggregate does not cause this License to apply to the other
nuclear@16 243 parts of the aggregate.
nuclear@16 244
nuclear@16 245 6. Conveying Non-Source Forms.
nuclear@16 246
nuclear@16 247 You may convey a covered work in object code form under the terms
nuclear@16 248 of sections 4 and 5, provided that you also convey the
nuclear@16 249 machine-readable Corresponding Source under the terms of this License,
nuclear@16 250 in one of these ways:
nuclear@16 251
nuclear@16 252 a) Convey the object code in, or embodied in, a physical product
nuclear@16 253 (including a physical distribution medium), accompanied by the
nuclear@16 254 Corresponding Source fixed on a durable physical medium
nuclear@16 255 customarily used for software interchange.
nuclear@16 256
nuclear@16 257 b) Convey the object code in, or embodied in, a physical product
nuclear@16 258 (including a physical distribution medium), accompanied by a
nuclear@16 259 written offer, valid for at least three years and valid for as
nuclear@16 260 long as you offer spare parts or customer support for that product
nuclear@16 261 model, to give anyone who possesses the object code either (1) a
nuclear@16 262 copy of the Corresponding Source for all the software in the
nuclear@16 263 product that is covered by this License, on a durable physical
nuclear@16 264 medium customarily used for software interchange, for a price no
nuclear@16 265 more than your reasonable cost of physically performing this
nuclear@16 266 conveying of source, or (2) access to copy the
nuclear@16 267 Corresponding Source from a network server at no charge.
nuclear@16 268
nuclear@16 269 c) Convey individual copies of the object code with a copy of the
nuclear@16 270 written offer to provide the Corresponding Source. This
nuclear@16 271 alternative is allowed only occasionally and noncommercially, and
nuclear@16 272 only if you received the object code with such an offer, in accord
nuclear@16 273 with subsection 6b.
nuclear@16 274
nuclear@16 275 d) Convey the object code by offering access from a designated
nuclear@16 276 place (gratis or for a charge), and offer equivalent access to the
nuclear@16 277 Corresponding Source in the same way through the same place at no
nuclear@16 278 further charge. You need not require recipients to copy the
nuclear@16 279 Corresponding Source along with the object code. If the place to
nuclear@16 280 copy the object code is a network server, the Corresponding Source
nuclear@16 281 may be on a different server (operated by you or a third party)
nuclear@16 282 that supports equivalent copying facilities, provided you maintain
nuclear@16 283 clear directions next to the object code saying where to find the
nuclear@16 284 Corresponding Source. Regardless of what server hosts the
nuclear@16 285 Corresponding Source, you remain obligated to ensure that it is
nuclear@16 286 available for as long as needed to satisfy these requirements.
nuclear@16 287
nuclear@16 288 e) Convey the object code using peer-to-peer transmission, provided
nuclear@16 289 you inform other peers where the object code and Corresponding
nuclear@16 290 Source of the work are being offered to the general public at no
nuclear@16 291 charge under subsection 6d.
nuclear@16 292
nuclear@16 293 A separable portion of the object code, whose source code is excluded
nuclear@16 294 from the Corresponding Source as a System Library, need not be
nuclear@16 295 included in conveying the object code work.
nuclear@16 296
nuclear@16 297 A "User Product" is either (1) a "consumer product", which means any
nuclear@16 298 tangible personal property which is normally used for personal, family,
nuclear@16 299 or household purposes, or (2) anything designed or sold for incorporation
nuclear@16 300 into a dwelling. In determining whether a product is a consumer product,
nuclear@16 301 doubtful cases shall be resolved in favor of coverage. For a particular
nuclear@16 302 product received by a particular user, "normally used" refers to a
nuclear@16 303 typical or common use of that class of product, regardless of the status
nuclear@16 304 of the particular user or of the way in which the particular user
nuclear@16 305 actually uses, or expects or is expected to use, the product. A product
nuclear@16 306 is a consumer product regardless of whether the product has substantial
nuclear@16 307 commercial, industrial or non-consumer uses, unless such uses represent
nuclear@16 308 the only significant mode of use of the product.
nuclear@16 309
nuclear@16 310 "Installation Information" for a User Product means any methods,
nuclear@16 311 procedures, authorization keys, or other information required to install
nuclear@16 312 and execute modified versions of a covered work in that User Product from
nuclear@16 313 a modified version of its Corresponding Source. The information must
nuclear@16 314 suffice to ensure that the continued functioning of the modified object
nuclear@16 315 code is in no case prevented or interfered with solely because
nuclear@16 316 modification has been made.
nuclear@16 317
nuclear@16 318 If you convey an object code work under this section in, or with, or
nuclear@16 319 specifically for use in, a User Product, and the conveying occurs as
nuclear@16 320 part of a transaction in which the right of possession and use of the
nuclear@16 321 User Product is transferred to the recipient in perpetuity or for a
nuclear@16 322 fixed term (regardless of how the transaction is characterized), the
nuclear@16 323 Corresponding Source conveyed under this section must be accompanied
nuclear@16 324 by the Installation Information. But this requirement does not apply
nuclear@16 325 if neither you nor any third party retains the ability to install
nuclear@16 326 modified object code on the User Product (for example, the work has
nuclear@16 327 been installed in ROM).
nuclear@16 328
nuclear@16 329 The requirement to provide Installation Information does not include a
nuclear@16 330 requirement to continue to provide support service, warranty, or updates
nuclear@16 331 for a work that has been modified or installed by the recipient, or for
nuclear@16 332 the User Product in which it has been modified or installed. Access to a
nuclear@16 333 network may be denied when the modification itself materially and
nuclear@16 334 adversely affects the operation of the network or violates the rules and
nuclear@16 335 protocols for communication across the network.
nuclear@16 336
nuclear@16 337 Corresponding Source conveyed, and Installation Information provided,
nuclear@16 338 in accord with this section must be in a format that is publicly
nuclear@16 339 documented (and with an implementation available to the public in
nuclear@16 340 source code form), and must require no special password or key for
nuclear@16 341 unpacking, reading or copying.
nuclear@16 342
nuclear@16 343 7. Additional Terms.
nuclear@16 344
nuclear@16 345 "Additional permissions" are terms that supplement the terms of this
nuclear@16 346 License by making exceptions from one or more of its conditions.
nuclear@16 347 Additional permissions that are applicable to the entire Program shall
nuclear@16 348 be treated as though they were included in this License, to the extent
nuclear@16 349 that they are valid under applicable law. If additional permissions
nuclear@16 350 apply only to part of the Program, that part may be used separately
nuclear@16 351 under those permissions, but the entire Program remains governed by
nuclear@16 352 this License without regard to the additional permissions.
nuclear@16 353
nuclear@16 354 When you convey a copy of a covered work, you may at your option
nuclear@16 355 remove any additional permissions from that copy, or from any part of
nuclear@16 356 it. (Additional permissions may be written to require their own
nuclear@16 357 removal in certain cases when you modify the work.) You may place
nuclear@16 358 additional permissions on material, added by you to a covered work,
nuclear@16 359 for which you have or can give appropriate copyright permission.
nuclear@16 360
nuclear@16 361 Notwithstanding any other provision of this License, for material you
nuclear@16 362 add to a covered work, you may (if authorized by the copyright holders of
nuclear@16 363 that material) supplement the terms of this License with terms:
nuclear@16 364
nuclear@16 365 a) Disclaiming warranty or limiting liability differently from the
nuclear@16 366 terms of sections 15 and 16 of this License; or
nuclear@16 367
nuclear@16 368 b) Requiring preservation of specified reasonable legal notices or
nuclear@16 369 author attributions in that material or in the Appropriate Legal
nuclear@16 370 Notices displayed by works containing it; or
nuclear@16 371
nuclear@16 372 c) Prohibiting misrepresentation of the origin of that material, or
nuclear@16 373 requiring that modified versions of such material be marked in
nuclear@16 374 reasonable ways as different from the original version; or
nuclear@16 375
nuclear@16 376 d) Limiting the use for publicity purposes of names of licensors or
nuclear@16 377 authors of the material; or
nuclear@16 378
nuclear@16 379 e) Declining to grant rights under trademark law for use of some
nuclear@16 380 trade names, trademarks, or service marks; or
nuclear@16 381
nuclear@16 382 f) Requiring indemnification of licensors and authors of that
nuclear@16 383 material by anyone who conveys the material (or modified versions of
nuclear@16 384 it) with contractual assumptions of liability to the recipient, for
nuclear@16 385 any liability that these contractual assumptions directly impose on
nuclear@16 386 those licensors and authors.
nuclear@16 387
nuclear@16 388 All other non-permissive additional terms are considered "further
nuclear@16 389 restrictions" within the meaning of section 10. If the Program as you
nuclear@16 390 received it, or any part of it, contains a notice stating that it is
nuclear@16 391 governed by this License along with a term that is a further
nuclear@16 392 restriction, you may remove that term. If a license document contains
nuclear@16 393 a further restriction but permits relicensing or conveying under this
nuclear@16 394 License, you may add to a covered work material governed by the terms
nuclear@16 395 of that license document, provided that the further restriction does
nuclear@16 396 not survive such relicensing or conveying.
nuclear@16 397
nuclear@16 398 If you add terms to a covered work in accord with this section, you
nuclear@16 399 must place, in the relevant source files, a statement of the
nuclear@16 400 additional terms that apply to those files, or a notice indicating
nuclear@16 401 where to find the applicable terms.
nuclear@16 402
nuclear@16 403 Additional terms, permissive or non-permissive, may be stated in the
nuclear@16 404 form of a separately written license, or stated as exceptions;
nuclear@16 405 the above requirements apply either way.
nuclear@16 406
nuclear@16 407 8. Termination.
nuclear@16 408
nuclear@16 409 You may not propagate or modify a covered work except as expressly
nuclear@16 410 provided under this License. Any attempt otherwise to propagate or
nuclear@16 411 modify it is void, and will automatically terminate your rights under
nuclear@16 412 this License (including any patent licenses granted under the third
nuclear@16 413 paragraph of section 11).
nuclear@16 414
nuclear@16 415 However, if you cease all violation of this License, then your
nuclear@16 416 license from a particular copyright holder is reinstated (a)
nuclear@16 417 provisionally, unless and until the copyright holder explicitly and
nuclear@16 418 finally terminates your license, and (b) permanently, if the copyright
nuclear@16 419 holder fails to notify you of the violation by some reasonable means
nuclear@16 420 prior to 60 days after the cessation.
nuclear@16 421
nuclear@16 422 Moreover, your license from a particular copyright holder is
nuclear@16 423 reinstated permanently if the copyright holder notifies you of the
nuclear@16 424 violation by some reasonable means, this is the first time you have
nuclear@16 425 received notice of violation of this License (for any work) from that
nuclear@16 426 copyright holder, and you cure the violation prior to 30 days after
nuclear@16 427 your receipt of the notice.
nuclear@16 428
nuclear@16 429 Termination of your rights under this section does not terminate the
nuclear@16 430 licenses of parties who have received copies or rights from you under
nuclear@16 431 this License. If your rights have been terminated and not permanently
nuclear@16 432 reinstated, you do not qualify to receive new licenses for the same
nuclear@16 433 material under section 10.
nuclear@16 434
nuclear@16 435 9. Acceptance Not Required for Having Copies.
nuclear@16 436
nuclear@16 437 You are not required to accept this License in order to receive or
nuclear@16 438 run a copy of the Program. Ancillary propagation of a covered work
nuclear@16 439 occurring solely as a consequence of using peer-to-peer transmission
nuclear@16 440 to receive a copy likewise does not require acceptance. However,
nuclear@16 441 nothing other than this License grants you permission to propagate or
nuclear@16 442 modify any covered work. These actions infringe copyright if you do
nuclear@16 443 not accept this License. Therefore, by modifying or propagating a
nuclear@16 444 covered work, you indicate your acceptance of this License to do so.
nuclear@16 445
nuclear@16 446 10. Automatic Licensing of Downstream Recipients.
nuclear@16 447
nuclear@16 448 Each time you convey a covered work, the recipient automatically
nuclear@16 449 receives a license from the original licensors, to run, modify and
nuclear@16 450 propagate that work, subject to this License. You are not responsible
nuclear@16 451 for enforcing compliance by third parties with this License.
nuclear@16 452
nuclear@16 453 An "entity transaction" is a transaction transferring control of an
nuclear@16 454 organization, or substantially all assets of one, or subdividing an
nuclear@16 455 organization, or merging organizations. If propagation of a covered
nuclear@16 456 work results from an entity transaction, each party to that
nuclear@16 457 transaction who receives a copy of the work also receives whatever
nuclear@16 458 licenses to the work the party's predecessor in interest had or could
nuclear@16 459 give under the previous paragraph, plus a right to possession of the
nuclear@16 460 Corresponding Source of the work from the predecessor in interest, if
nuclear@16 461 the predecessor has it or can get it with reasonable efforts.
nuclear@16 462
nuclear@16 463 You may not impose any further restrictions on the exercise of the
nuclear@16 464 rights granted or affirmed under this License. For example, you may
nuclear@16 465 not impose a license fee, royalty, or other charge for exercise of
nuclear@16 466 rights granted under this License, and you may not initiate litigation
nuclear@16 467 (including a cross-claim or counterclaim in a lawsuit) alleging that
nuclear@16 468 any patent claim is infringed by making, using, selling, offering for
nuclear@16 469 sale, or importing the Program or any portion of it.
nuclear@16 470
nuclear@16 471 11. Patents.
nuclear@16 472
nuclear@16 473 A "contributor" is a copyright holder who authorizes use under this
nuclear@16 474 License of the Program or a work on which the Program is based. The
nuclear@16 475 work thus licensed is called the contributor's "contributor version".
nuclear@16 476
nuclear@16 477 A contributor's "essential patent claims" are all patent claims
nuclear@16 478 owned or controlled by the contributor, whether already acquired or
nuclear@16 479 hereafter acquired, that would be infringed by some manner, permitted
nuclear@16 480 by this License, of making, using, or selling its contributor version,
nuclear@16 481 but do not include claims that would be infringed only as a
nuclear@16 482 consequence of further modification of the contributor version. For
nuclear@16 483 purposes of this definition, "control" includes the right to grant
nuclear@16 484 patent sublicenses in a manner consistent with the requirements of
nuclear@16 485 this License.
nuclear@16 486
nuclear@16 487 Each contributor grants you a non-exclusive, worldwide, royalty-free
nuclear@16 488 patent license under the contributor's essential patent claims, to
nuclear@16 489 make, use, sell, offer for sale, import and otherwise run, modify and
nuclear@16 490 propagate the contents of its contributor version.
nuclear@16 491
nuclear@16 492 In the following three paragraphs, a "patent license" is any express
nuclear@16 493 agreement or commitment, however denominated, not to enforce a patent
nuclear@16 494 (such as an express permission to practice a patent or covenant not to
nuclear@16 495 sue for patent infringement). To "grant" such a patent license to a
nuclear@16 496 party means to make such an agreement or commitment not to enforce a
nuclear@16 497 patent against the party.
nuclear@16 498
nuclear@16 499 If you convey a covered work, knowingly relying on a patent license,
nuclear@16 500 and the Corresponding Source of the work is not available for anyone
nuclear@16 501 to copy, free of charge and under the terms of this License, through a
nuclear@16 502 publicly available network server or other readily accessible means,
nuclear@16 503 then you must either (1) cause the Corresponding Source to be so
nuclear@16 504 available, or (2) arrange to deprive yourself of the benefit of the
nuclear@16 505 patent license for this particular work, or (3) arrange, in a manner
nuclear@16 506 consistent with the requirements of this License, to extend the patent
nuclear@16 507 license to downstream recipients. "Knowingly relying" means you have
nuclear@16 508 actual knowledge that, but for the patent license, your conveying the
nuclear@16 509 covered work in a country, or your recipient's use of the covered work
nuclear@16 510 in a country, would infringe one or more identifiable patents in that
nuclear@16 511 country that you have reason to believe are valid.
nuclear@16 512
nuclear@16 513 If, pursuant to or in connection with a single transaction or
nuclear@16 514 arrangement, you convey, or propagate by procuring conveyance of, a
nuclear@16 515 covered work, and grant a patent license to some of the parties
nuclear@16 516 receiving the covered work authorizing them to use, propagate, modify
nuclear@16 517 or convey a specific copy of the covered work, then the patent license
nuclear@16 518 you grant is automatically extended to all recipients of the covered
nuclear@16 519 work and works based on it.
nuclear@16 520
nuclear@16 521 A patent license is "discriminatory" if it does not include within
nuclear@16 522 the scope of its coverage, prohibits the exercise of, or is
nuclear@16 523 conditioned on the non-exercise of one or more of the rights that are
nuclear@16 524 specifically granted under this License. You may not convey a covered
nuclear@16 525 work if you are a party to an arrangement with a third party that is
nuclear@16 526 in the business of distributing software, under which you make payment
nuclear@16 527 to the third party based on the extent of your activity of conveying
nuclear@16 528 the work, and under which the third party grants, to any of the
nuclear@16 529 parties who would receive the covered work from you, a discriminatory
nuclear@16 530 patent license (a) in connection with copies of the covered work
nuclear@16 531 conveyed by you (or copies made from those copies), or (b) primarily
nuclear@16 532 for and in connection with specific products or compilations that
nuclear@16 533 contain the covered work, unless you entered into that arrangement,
nuclear@16 534 or that patent license was granted, prior to 28 March 2007.
nuclear@16 535
nuclear@16 536 Nothing in this License shall be construed as excluding or limiting
nuclear@16 537 any implied license or other defenses to infringement that may
nuclear@16 538 otherwise be available to you under applicable patent law.
nuclear@16 539
nuclear@16 540 12. No Surrender of Others' Freedom.
nuclear@16 541
nuclear@16 542 If conditions are imposed on you (whether by court order, agreement or
nuclear@16 543 otherwise) that contradict the conditions of this License, they do not
nuclear@16 544 excuse you from the conditions of this License. If you cannot convey a
nuclear@16 545 covered work so as to satisfy simultaneously your obligations under this
nuclear@16 546 License and any other pertinent obligations, then as a consequence you may
nuclear@16 547 not convey it at all. For example, if you agree to terms that obligate you
nuclear@16 548 to collect a royalty for further conveying from those to whom you convey
nuclear@16 549 the Program, the only way you could satisfy both those terms and this
nuclear@16 550 License would be to refrain entirely from conveying the Program.
nuclear@16 551
nuclear@16 552 13. Use with the GNU Affero General Public License.
nuclear@16 553
nuclear@16 554 Notwithstanding any other provision of this License, you have
nuclear@16 555 permission to link or combine any covered work with a work licensed
nuclear@16 556 under version 3 of the GNU Affero General Public License into a single
nuclear@16 557 combined work, and to convey the resulting work. The terms of this
nuclear@16 558 License will continue to apply to the part which is the covered work,
nuclear@16 559 but the special requirements of the GNU Affero General Public License,
nuclear@16 560 section 13, concerning interaction through a network will apply to the
nuclear@16 561 combination as such.
nuclear@16 562
nuclear@16 563 14. Revised Versions of this License.
nuclear@16 564
nuclear@16 565 The Free Software Foundation may publish revised and/or new versions of
nuclear@16 566 the GNU General Public License from time to time. Such new versions will
nuclear@16 567 be similar in spirit to the present version, but may differ in detail to
nuclear@16 568 address new problems or concerns.
nuclear@16 569
nuclear@16 570 Each version is given a distinguishing version number. If the
nuclear@16 571 Program specifies that a certain numbered version of the GNU General
nuclear@16 572 Public License "or any later version" applies to it, you have the
nuclear@16 573 option of following the terms and conditions either of that numbered
nuclear@16 574 version or of any later version published by the Free Software
nuclear@16 575 Foundation. If the Program does not specify a version number of the
nuclear@16 576 GNU General Public License, you may choose any version ever published
nuclear@16 577 by the Free Software Foundation.
nuclear@16 578
nuclear@16 579 If the Program specifies that a proxy can decide which future
nuclear@16 580 versions of the GNU General Public License can be used, that proxy's
nuclear@16 581 public statement of acceptance of a version permanently authorizes you
nuclear@16 582 to choose that version for the Program.
nuclear@16 583
nuclear@16 584 Later license versions may give you additional or different
nuclear@16 585 permissions. However, no additional obligations are imposed on any
nuclear@16 586 author or copyright holder as a result of your choosing to follow a
nuclear@16 587 later version.
nuclear@16 588
nuclear@16 589 15. Disclaimer of Warranty.
nuclear@16 590
nuclear@16 591 THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
nuclear@16 592 APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
nuclear@16 593 HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
nuclear@16 594 OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
nuclear@16 595 THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
nuclear@16 596 PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
nuclear@16 597 IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
nuclear@16 598 ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
nuclear@16 599
nuclear@16 600 16. Limitation of Liability.
nuclear@16 601
nuclear@16 602 IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
nuclear@16 603 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
nuclear@16 604 THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
nuclear@16 605 GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
nuclear@16 606 USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
nuclear@16 607 DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
nuclear@16 608 PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
nuclear@16 609 EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
nuclear@16 610 SUCH DAMAGES.
nuclear@16 611
nuclear@16 612 17. Interpretation of Sections 15 and 16.
nuclear@16 613
nuclear@16 614 If the disclaimer of warranty and limitation of liability provided
nuclear@16 615 above cannot be given local legal effect according to their terms,
nuclear@16 616 reviewing courts shall apply local law that most closely approximates
nuclear@16 617 an absolute waiver of all civil liability in connection with the
nuclear@16 618 Program, unless a warranty or assumption of liability accompanies a
nuclear@16 619 copy of the Program in return for a fee.
nuclear@16 620
nuclear@16 621 END OF TERMS AND CONDITIONS
nuclear@16 622
nuclear@16 623 How to Apply These Terms to Your New Programs
nuclear@16 624
nuclear@16 625 If you develop a new program, and you want it to be of the greatest
nuclear@16 626 possible use to the public, the best way to achieve this is to make it
nuclear@16 627 free software which everyone can redistribute and change under these terms.
nuclear@16 628
nuclear@16 629 To do so, attach the following notices to the program. It is safest
nuclear@16 630 to attach them to the start of each source file to most effectively
nuclear@16 631 state the exclusion of warranty; and each file should have at least
nuclear@16 632 the "copyright" line and a pointer to where the full notice is found.
nuclear@16 633
nuclear@16 634 <one line to give the program's name and a brief idea of what it does.>
nuclear@16 635 Copyright (C) <year> <name of author>
nuclear@16 636
nuclear@16 637 This program is free software: you can redistribute it and/or modify
nuclear@16 638 it under the terms of the GNU General Public License as published by
nuclear@16 639 the Free Software Foundation, either version 3 of the License, or
nuclear@16 640 (at your option) any later version.
nuclear@16 641
nuclear@16 642 This program is distributed in the hope that it will be useful,
nuclear@16 643 but WITHOUT ANY WARRANTY; without even the implied warranty of
nuclear@16 644 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
nuclear@16 645 GNU General Public License for more details.
nuclear@16 646
nuclear@16 647 You should have received a copy of the GNU General Public License
nuclear@16 648 along with this program. If not, see <http://www.gnu.org/licenses/>.
nuclear@16 649
nuclear@16 650 Also add information on how to contact you by electronic and paper mail.
nuclear@16 651
nuclear@16 652 If the program does terminal interaction, make it output a short
nuclear@16 653 notice like this when it starts in an interactive mode:
nuclear@16 654
nuclear@16 655 <program> Copyright (C) <year> <name of author>
nuclear@16 656 This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
nuclear@16 657 This is free software, and you are welcome to redistribute it
nuclear@16 658 under certain conditions; type `show c' for details.
nuclear@16 659
nuclear@16 660 The hypothetical commands `show w' and `show c' should show the appropriate
nuclear@16 661 parts of the General Public License. Of course, your program's commands
nuclear@16 662 might be different; for a GUI interface, you would use an "about box".
nuclear@16 663
nuclear@16 664 You should also get your employer (if you work as a programmer) or school,
nuclear@16 665 if any, to sign a "copyright disclaimer" for the program, if necessary.
nuclear@16 666 For more information on this, and how to apply and follow the GNU GPL, see
nuclear@16 667 <http://www.gnu.org/licenses/>.
nuclear@16 668
nuclear@16 669 The GNU General Public License does not permit incorporating your program
nuclear@16 670 into proprietary programs. If your program is a subroutine library, you
nuclear@16 671 may consider it more useful to permit linking proprietary applications with
nuclear@16 672 the library. If this is what you want to do, use the GNU Lesser General
nuclear@16 673 Public License instead of this License. But first, please read
nuclear@16 674 <http://www.gnu.org/philosophy/why-not-lgpl.html>.
