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