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