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