jpayne@68 108 <h2 class="heading"> Preamble </h2>
jpayne@68 109
jpayne@68 110 <p>The GNU General Public License is a free, copyleft license for
jpayne@68 111 software and other kinds of works.
jpayne@68 112 </p>
jpayne@68 113 <p>The licenses for most software and other practical works are designed
jpayne@68 114 to take away your freedom to share and change the works. By contrast,
jpayne@68 115 the GNU General Public License is intended to guarantee your freedom
jpayne@68 116 to share and change all versions of a program&mdash;to make sure it remains
jpayne@68 117 free software for all its users. We, the Free Software Foundation,
jpayne@68 118 use the GNU General Public License for most of our software; it
jpayne@68 119 applies also to any other work released this way by its authors. You
jpayne@68 120 can apply it to your programs, too.
jpayne@68 121 </p>
jpayne@68 122 <p>When we speak of free software, we are referring to freedom, not
jpayne@68 123 price. Our General Public Licenses are designed to make sure that you
jpayne@68 124 have the freedom to distribute copies of free software (and charge for
jpayne@68 125 them if you wish), that you receive source code or can get it if you
jpayne@68 126 want it, that you can change the software or use pieces of it in new
jpayne@68 127 free programs, and that you know you can do these things.
jpayne@68 128 </p>
jpayne@68 129 <p>To protect your rights, we need to prevent others from denying you
jpayne@68 130 these rights or asking you to surrender the rights. Therefore, you
jpayne@68 131 have certain responsibilities if you distribute copies of the
jpayne@68 132 software, or if you modify it: responsibilities to respect the freedom
jpayne@68 133 of others.
jpayne@68 134 </p>
jpayne@68 135 <p>For example, if you distribute copies of such a program, whether
jpayne@68 136 gratis or for a fee, you must pass on to the recipients the same
jpayne@68 137 freedoms that you received. You must make sure that they, too,
jpayne@68 138 receive or can get the source code. And you must show them these
jpayne@68 139 terms so they know their rights.
jpayne@68 140 </p>
jpayne@68 141 <p>Developers that use the GNU GPL protect your rights with two steps:
jpayne@68 142 (1) assert copyright on the software, and (2) offer you this License
jpayne@68 143 giving you legal permission to copy, distribute and/or modify it.
jpayne@68 144 </p>
jpayne@68 145 <p>For the developers' and authors' protection, the GPL clearly explains
jpayne@68 146 that there is no warranty for this free software. For both users' and
jpayne@68 147 authors' sake, the GPL requires that modified versions be marked as
jpayne@68 148 changed, so that their problems will not be attributed erroneously to
jpayne@68 149 authors of previous versions.
jpayne@68 150 </p>
jpayne@68 151 <p>Some devices are designed to deny users access to install or run
jpayne@68 152 modified versions of the software inside them, although the
jpayne@68 153 manufacturer can do so. This is fundamentally incompatible with the
jpayne@68 154 aim of protecting users' freedom to change the software. The
jpayne@68 155 systematic pattern of such abuse occurs in the area of products for
jpayne@68 156 individuals to use, which is precisely where it is most unacceptable.
jpayne@68 157 Therefore, we have designed this version of the GPL to prohibit the
jpayne@68 158 practice for those products. If such problems arise substantially in
jpayne@68 159 other domains, we stand ready to extend this provision to those
jpayne@68 160 domains in future versions of the GPL, as needed to protect the
jpayne@68 161 freedom of users.
jpayne@68 162 </p>
jpayne@68 163 <p>Finally, every program is threatened constantly by software patents.
jpayne@68 164 States should not allow patents to restrict development and use of
jpayne@68 165 software on general-purpose computers, but in those that do, we wish
jpayne@68 166 to avoid the special danger that patents applied to a free program
jpayne@68 167 could make it effectively proprietary. To prevent this, the GPL
jpayne@68 168 assures that patents cannot be used to render the program non-free.
jpayne@68 169 </p>
jpayne@68 170 <p>The precise terms and conditions for copying, distribution and
jpayne@68 171 modification follow.
jpayne@68 172 </p>
jpayne@68 173 <a name="SEC41"></a>
jpayne@68 174 <h2 class="heading"> TERMS AND CONDITIONS </h2>
jpayne@68 175
jpayne@68 176 <ol>
jpayne@68 177 <li> Definitions.
jpayne@68 178
jpayne@68 179 <p>&ldquo;This License&rdquo; refers to version 3 of the GNU General Public License.
jpayne@68 180 </p>
jpayne@68 181 <p>&ldquo;Copyright&rdquo; also means copyright-like laws that apply to other kinds
jpayne@68 182 of works, such as semiconductor masks.
jpayne@68 183 </p>
jpayne@68 184 <p>&ldquo;The Program&rdquo; refers to any copyrightable work licensed under this
jpayne@68 185 License. Each licensee is addressed as &ldquo;you&rdquo;. &ldquo;Licensees&rdquo; and
jpayne@68 186 &ldquo;recipients&rdquo; may be individuals or organizations.
jpayne@68 187 </p>
jpayne@68 188 <p>To &ldquo;modify&rdquo; a work means to copy from or adapt all or part of the work
jpayne@68 189 in a fashion requiring copyright permission, other than the making of
jpayne@68 190 an exact copy. The resulting work is called a &ldquo;modified version&rdquo; of
jpayne@68 191 the earlier work or a work &ldquo;based on&rdquo; the earlier work.
jpayne@68 192 </p>
jpayne@68 193 <p>A &ldquo;covered work&rdquo; means either the unmodified Program or a work based
jpayne@68 194 on the Program.
jpayne@68 195 </p>
jpayne@68 196 <p>To &ldquo;propagate&rdquo; a work means to do anything with it that, without
jpayne@68 197 permission, would make you directly or secondarily liable for
jpayne@68 198 infringement under applicable copyright law, except executing it on a
jpayne@68 199 computer or modifying a private copy. Propagation includes copying,
jpayne@68 200 distribution (with or without modification), making available to the
jpayne@68 201 public, and in some countries other activities as well.
jpayne@68 202 </p>
jpayne@68 203 <p>To &ldquo;convey&rdquo; a work means any kind of propagation that enables other
jpayne@68 204 parties to make or receive copies. Mere interaction with a user
jpayne@68 205 through a computer network, with no transfer of a copy, is not
jpayne@68 206 conveying.
jpayne@68 207 </p>
jpayne@68 208 <p>An interactive user interface displays &ldquo;Appropriate Legal Notices&rdquo; to
jpayne@68 209 the extent that it includes a convenient and prominently visible
jpayne@68 210 feature that (1) displays an appropriate copyright notice, and (2)
jpayne@68 211 tells the user that there is no warranty for the work (except to the
jpayne@68 212 extent that warranties are provided), that licensees may convey the
jpayne@68 213 work under this License, and how to view a copy of this License. If
jpayne@68 214 the interface presents a list of user commands or options, such as a
jpayne@68 215 menu, a prominent item in the list meets this criterion.
jpayne@68 216 </p>
jpayne@68 217 </li><li> Source Code.
jpayne@68 218
jpayne@68 219 <p>The &ldquo;source code&rdquo; for a work means the preferred form of the work for
jpayne@68 220 making modifications to it. &ldquo;Object code&rdquo; means any non-source form
jpayne@68 221 of a work.
jpayne@68 222 </p>
jpayne@68 223 <p>A &ldquo;Standard Interface&rdquo; means an interface that either is an official
jpayne@68 224 standard defined by a recognized standards body, or, in the case of
jpayne@68 225 interfaces specified for a particular programming language, one that
jpayne@68 226 is widely used among developers working in that language.
jpayne@68 227 </p>
jpayne@68 228 <p>The &ldquo;System Libraries&rdquo; of an executable work include anything, other
jpayne@68 229 than the work as a whole, that (a) is included in the normal form of
jpayne@68 230 packaging a Major Component, but which is not part of that Major
jpayne@68 231 Component, and (b) serves only to enable use of the work with that
jpayne@68 232 Major Component, or to implement a Standard Interface for which an
jpayne@68 233 implementation is available to the public in source code form. A
jpayne@68 234 &ldquo;Major Component&rdquo;, in this context, means a major essential component
jpayne@68 235 (kernel, window system, and so on) of the specific operating system
jpayne@68 236 (if any) on which the executable work runs, or a compiler used to
jpayne@68 237 produce the work, or an object code interpreter used to run it.
jpayne@68 238 </p>
jpayne@68 239 <p>The &ldquo;Corresponding Source&rdquo; for a work in object code form means all
jpayne@68 240 the source code needed to generate, install, and (for an executable
jpayne@68 241 work) run the object code and to modify the work, including scripts to
jpayne@68 242 control those activities. However, it does not include the work's
jpayne@68 243 System Libraries, or general-purpose tools or generally available free
jpayne@68 244 programs which are used unmodified in performing those activities but
jpayne@68 245 which are not part of the work. For example, Corresponding Source
jpayne@68 246 includes interface definition files associated with source files for
jpayne@68 247 the work, and the source code for shared libraries and dynamically
jpayne@68 248 linked subprograms that the work is specifically designed to require,
jpayne@68 249 such as by intimate data communication or control flow between those
jpayne@68 250 subprograms and other parts of the work.
jpayne@68 251 </p>
jpayne@68 252 <p>The Corresponding Source need not include anything that users can
jpayne@68 253 regenerate automatically from other parts of the Corresponding Source.
jpayne@68 254 </p>
jpayne@68 255 <p>The Corresponding Source for a work in source code form is that same
jpayne@68 256 work.
jpayne@68 257 </p>
jpayne@68 258 </li><li> Basic Permissions.
jpayne@68 259
jpayne@68 260 <p>All rights granted under this License are granted for the term of
jpayne@68 261 copyright on the Program, and are irrevocable provided the stated
jpayne@68 262 conditions are met. This License explicitly affirms your unlimited
jpayne@68 263 permission to run the unmodified Program. The output from running a
jpayne@68 264 covered work is covered by this License only if the output, given its
jpayne@68 265 content, constitutes a covered work. This License acknowledges your
jpayne@68 266 rights of fair use or other equivalent, as provided by copyright law.
jpayne@68 267 </p>
jpayne@68 268 <p>You may make, run and propagate covered works that you do not convey,
jpayne@68 269 without conditions so long as your license otherwise remains in force.
jpayne@68 270 You may convey covered works to others for the sole purpose of having
jpayne@68 271 them make modifications exclusively for you, or provide you with
jpayne@68 272 facilities for running those works, provided that you comply with the
jpayne@68 273 terms of this License in conveying all material for which you do not
jpayne@68 274 control copyright. Those thus making or running the covered works for
jpayne@68 275 you must do so exclusively on your behalf, under your direction and
jpayne@68 276 control, on terms that prohibit them from making any copies of your
jpayne@68 277 copyrighted material outside their relationship with you.
jpayne@68 278 </p>
jpayne@68 279 <p>Conveying under any other circumstances is permitted solely under the
jpayne@68 280 conditions stated below. Sublicensing is not allowed; section 10
jpayne@68 281 makes it unnecessary.
jpayne@68 282 </p>
jpayne@68 283 </li><li> Protecting Users' Legal Rights From Anti-Circumvention Law.
jpayne@68 284
jpayne@68 285 <p>No covered work shall be deemed part of an effective technological
jpayne@68 286 measure under any applicable law fulfilling obligations under article
jpayne@68 287 11 of the WIPO copyright treaty adopted on 20 December 1996, or
jpayne@68 288 similar laws prohibiting or restricting circumvention of such
jpayne@68 289 measures.
jpayne@68 290 </p>
jpayne@68 291 <p>When you convey a covered work, you waive any legal power to forbid
jpayne@68 292 circumvention of technological measures to the extent such
jpayne@68 293 circumvention is effected by exercising rights under this License with
jpayne@68 294 respect to the covered work, and you disclaim any intention to limit
jpayne@68 295 operation or modification of the work as a means of enforcing, against
jpayne@68 296 the work's users, your or third parties' legal rights to forbid
jpayne@68 297 circumvention of technological measures.
jpayne@68 298 </p>
jpayne@68 299 </li><li> Conveying Verbatim Copies.
jpayne@68 300
jpayne@68 301 <p>You may convey verbatim copies of the Program's source code as you
jpayne@68 302 receive it, in any medium, provided that you conspicuously and
jpayne@68 303 appropriately publish on each copy an appropriate copyright notice;
jpayne@68 304 keep intact all notices stating that this License and any
jpayne@68 305 non-permissive terms added in accord with section 7 apply to the code;
jpayne@68 306 keep intact all notices of the absence of any warranty; and give all
jpayne@68 307 recipients a copy of this License along with the Program.
jpayne@68 308 </p>
jpayne@68 309 <p>You may charge any price or no price for each copy that you convey,
jpayne@68 310 and you may offer support or warranty protection for a fee.
jpayne@68 311 </p>
jpayne@68 312 </li><li> Conveying Modified Source Versions.
jpayne@68 313
jpayne@68 314 <p>You may convey a work based on the Program, or the modifications to
jpayne@68 315 produce it from the Program, in the form of source code under the
jpayne@68 316 terms of section 4, provided that you also meet all of these
jpayne@68 317 conditions:
jpayne@68 318 </p>
jpayne@68 319 <ol>
jpayne@68 320 <li>
jpayne@68 321 The work must carry prominent notices stating that you modified it,
jpayne@68 322 and giving a relevant date.
jpayne@68 323
jpayne@68 324 </li><li>
jpayne@68 325 The work must carry prominent notices stating that it is released
jpayne@68 326 under this License and any conditions added under section 7. This
jpayne@68 327 requirement modifies the requirement in section 4 to &ldquo;keep intact all
jpayne@68 328 notices&rdquo;.
jpayne@68 329
jpayne@68 330 </li><li>
jpayne@68 331 You must license the entire work, as a whole, under this License to
jpayne@68 332 anyone who comes into possession of a copy. This License will
jpayne@68 333 therefore apply, along with any applicable section 7 additional terms,
jpayne@68 334 to the whole of the work, and all its parts, regardless of how they
jpayne@68 335 are packaged. This License gives no permission to license the work in
jpayne@68 336 any other way, but it does not invalidate such permission if you have
jpayne@68 337 separately received it.
jpayne@68 338
jpayne@68 339 </li><li>
jpayne@68 340 If the work has interactive user interfaces, each must display
jpayne@68 341 Appropriate Legal Notices; however, if the Program has interactive
jpayne@68 342 interfaces that do not display Appropriate Legal Notices, your work
jpayne@68 343 need not make them do so.
jpayne@68 344 </li></ol>
jpayne@68 345
jpayne@68 346 <p>A compilation of a covered work with other separate and independent
jpayne@68 347 works, which are not by their nature extensions of the covered work,
jpayne@68 348 and which are not combined with it such as to form a larger program,
jpayne@68 349 in or on a volume of a storage or distribution medium, is called an
jpayne@68 350 &ldquo;aggregate&rdquo; if the compilation and its resulting copyright are not
jpayne@68 351 used to limit the access or legal rights of the compilation's users
jpayne@68 352 beyond what the individual works permit. Inclusion of a covered work
jpayne@68 353 in an aggregate does not cause this License to apply to the other
jpayne@68 354 parts of the aggregate.
jpayne@68 355 </p>
jpayne@68 356 </li><li> Conveying Non-Source Forms.
jpayne@68 357
jpayne@68 358 <p>You may convey a covered work in object code form under the terms of
jpayne@68 359 sections 4 and 5, provided that you also convey the machine-readable
jpayne@68 360 Corresponding Source under the terms of this License, in one of these
jpayne@68 361 ways:
jpayne@68 362 </p>
jpayne@68 363 <ol>
jpayne@68 364 <li>
jpayne@68 365 Convey the object code in, or embodied in, a physical product
jpayne@68 366 (including a physical distribution medium), accompanied by the
jpayne@68 367 Corresponding Source fixed on a durable physical medium customarily
jpayne@68 368 used for software interchange.
jpayne@68 369
jpayne@68 370 </li><li>
jpayne@68 371 Convey the object code in, or embodied in, a physical product
jpayne@68 372 (including a physical distribution medium), accompanied by a written
jpayne@68 373 offer, valid for at least three years and valid for as long as you
jpayne@68 374 offer spare parts or customer support for that product model, to give
jpayne@68 375 anyone who possesses the object code either (1) a copy of the
jpayne@68 376 Corresponding Source for all the software in the product that is
jpayne@68 377 covered by this License, on a durable physical medium customarily used
jpayne@68 378 for software interchange, for a price no more than your reasonable
jpayne@68 379 cost of physically performing this conveying of source, or (2) access
jpayne@68 380 to copy the Corresponding Source from a network server at no charge.
jpayne@68 381
jpayne@68 382 </li><li>
jpayne@68 383 Convey individual copies of the object code with a copy of the written
jpayne@68 384 offer to provide the Corresponding Source. This alternative is
jpayne@68 385 allowed only occasionally and noncommercially, and only if you
jpayne@68 386 received the object code with such an offer, in accord with subsection
jpayne@68 387 6b.
jpayne@68 388
jpayne@68 389 </li><li>
jpayne@68 390 Convey the object code by offering access from a designated place
jpayne@68 391 (gratis or for a charge), and offer equivalent access to the
jpayne@68 392 Corresponding Source in the same way through the same place at no
jpayne@68 393 further charge. You need not require recipients to copy the
jpayne@68 394 Corresponding Source along with the object code. If the place to copy
jpayne@68 395 the object code is a network server, the Corresponding Source may be
jpayne@68 396 on a different server (operated by you or a third party) that supports
jpayne@68 397 equivalent copying facilities, provided you maintain clear directions
jpayne@68 398 next to the object code saying where to find the Corresponding Source.
jpayne@68 399 Regardless of what server hosts the Corresponding Source, you remain
jpayne@68 400 obligated to ensure that it is available for as long as needed to
jpayne@68 401 satisfy these requirements.
jpayne@68 402
jpayne@68 403 </li><li>
jpayne@68 404 Convey the object code using peer-to-peer transmission, provided you
jpayne@68 405 inform other peers where the object code and Corresponding Source of
jpayne@68 406 the work are being offered to the general public at no charge under
jpayne@68 407 subsection 6d.
jpayne@68 408
jpayne@68 409 </li></ol>
jpayne@68 410
jpayne@68 411 <p>A separable portion of the object code, whose source code is excluded
jpayne@68 412 from the Corresponding Source as a System Library, need not be
jpayne@68 413 included in conveying the object code work.
jpayne@68 414 </p>
jpayne@68 415 <p>A &ldquo;User Product&rdquo; is either (1) a &ldquo;consumer product&rdquo;, which means any
jpayne@68 416 tangible personal property which is normally used for personal,
jpayne@68 417 family, or household purposes, or (2) anything designed or sold for
jpayne@68 418 incorporation into a dwelling. In determining whether a product is a
jpayne@68 419 consumer product, doubtful cases shall be resolved in favor of
jpayne@68 420 coverage. For a particular product received by a particular user,
jpayne@68 421 &ldquo;normally used&rdquo; refers to a typical or common use of that class of
jpayne@68 422 product, regardless of the status of the particular user or of the way
jpayne@68 423 in which the particular user actually uses, or expects or is expected
jpayne@68 424 to use, the product. A product is a consumer product regardless of
jpayne@68 425 whether the product has substantial commercial, industrial or
jpayne@68 426 non-consumer uses, unless such uses represent the only significant
jpayne@68 427 mode of use of the product.
jpayne@68 428 </p>
jpayne@68 429 <p>&ldquo;Installation Information&rdquo; for a User Product means any methods,
jpayne@68 430 procedures, authorization keys, or other information required to
jpayne@68 431 install and execute modified versions of a covered work in that User
jpayne@68 432 Product from a modified version of its Corresponding Source. The
jpayne@68 433 information must suffice to ensure that the continued functioning of
jpayne@68 434 the modified object code is in no case prevented or interfered with
jpayne@68 435 solely because modification has been made.
jpayne@68 436 </p>
jpayne@68 437 <p>If you convey an object code work under this section in, or with, or
jpayne@68 438 specifically for use in, a User Product, and the conveying occurs as
jpayne@68 439 part of a transaction in which the right of possession and use of the
jpayne@68 440 User Product is transferred to the recipient in perpetuity or for a
jpayne@68 441 fixed term (regardless of how the transaction is characterized), the
jpayne@68 442 Corresponding Source conveyed under this section must be accompanied
jpayne@68 443 by the Installation Information. But this requirement does not apply
jpayne@68 444 if neither you nor any third party retains the ability to install
jpayne@68 445 modified object code on the User Product (for example, the work has
jpayne@68 446 been installed in ROM).
jpayne@68 447 </p>
jpayne@68 448 <p>The requirement to provide Installation Information does not include a
jpayne@68 449 requirement to continue to provide support service, warranty, or
jpayne@68 450 updates for a work that has been modified or installed by the
jpayne@68 451 recipient, or for the User Product in which it has been modified or
jpayne@68 452 installed. Access to a network may be denied when the modification
jpayne@68 453 itself materially and adversely affects the operation of the network
jpayne@68 454 or violates the rules and protocols for communication across the
jpayne@68 455 network.
jpayne@68 456 </p>
jpayne@68 457 <p>Corresponding Source conveyed, and Installation Information provided,
jpayne@68 458 in accord with this section must be in a format that is publicly
jpayne@68 459 documented (and with an implementation available to the public in
jpayne@68 460 source code form), and must require no special password or key for
jpayne@68 461 unpacking, reading or copying.
jpayne@68 462 </p>
jpayne@68 463 </li><li> Additional Terms.
jpayne@68 464
jpayne@68 465 <p>&ldquo;Additional permissions&rdquo; are terms that supplement the terms of this
jpayne@68 466 License by making exceptions from one or more of its conditions.
jpayne@68 467 Additional permissions that are applicable to the entire Program shall
jpayne@68 468 be treated as though they were included in this License, to the extent
jpayne@68 469 that they are valid under applicable law. If additional permissions
jpayne@68 470 apply only to part of the Program, that part may be used separately
jpayne@68 471 under those permissions, but the entire Program remains governed by
jpayne@68 472 this License without regard to the additional permissions.
jpayne@68 473 </p>
jpayne@68 474 <p>When you convey a copy of a covered work, you may at your option
jpayne@68 475 remove any additional permissions from that copy, or from any part of
jpayne@68 476 it. (Additional permissions may be written to require their own
jpayne@68 477 removal in certain cases when you modify the work.) You may place
jpayne@68 478 additional permissions on material, added by you to a covered work,
jpayne@68 479 for which you have or can give appropriate copyright permission.
jpayne@68 480 </p>
jpayne@68 481 <p>Notwithstanding any other provision of this License, for material you
jpayne@68 482 add to a covered work, you may (if authorized by the copyright holders
jpayne@68 483 of that material) supplement the terms of this License with terms:
jpayne@68 484 </p>
jpayne@68 485 <ol>
jpayne@68 486 <li>
jpayne@68 487 Disclaiming warranty or limiting liability differently from the terms
jpayne@68 488 of sections 15 and 16 of this License; or
jpayne@68 489
jpayne@68 490 </li><li>
jpayne@68 491 Requiring preservation of specified reasonable legal notices or author
jpayne@68 492 attributions in that material or in the Appropriate Legal Notices
jpayne@68 493 displayed by works containing it; or
jpayne@68 494
jpayne@68 495 </li><li>
jpayne@68 496 Prohibiting misrepresentation of the origin of that material, or
jpayne@68 497 requiring that modified versions of such material be marked in
jpayne@68 498 reasonable ways as different from the original version; or
jpayne@68 499
jpayne@68 500 </li><li>
jpayne@68 501 Limiting the use for publicity purposes of names of licensors or
jpayne@68 502 authors of the material; or
jpayne@68 503
jpayne@68 504 </li><li>
jpayne@68 505 Declining to grant rights under trademark law for use of some trade
jpayne@68 506 names, trademarks, or service marks; or
jpayne@68 507
jpayne@68 508 </li><li>
jpayne@68 509 Requiring indemnification of licensors and authors of that material by
jpayne@68 510 anyone who conveys the material (or modified versions of it) with
jpayne@68 511 contractual assumptions of liability to the recipient, for any
jpayne@68 512 liability that these contractual assumptions directly impose on those
jpayne@68 513 licensors and authors.
jpayne@68 514 </li></ol>
jpayne@68 515
jpayne@68 516 <p>All other non-permissive additional terms are considered &ldquo;further
jpayne@68 517 restrictions&rdquo; within the meaning of section 10. If the Program as you
jpayne@68 518 received it, or any part of it, contains a notice stating that it is
jpayne@68 519 governed by this License along with a term that is a further
jpayne@68 520 restriction, you may remove that term. If a license document contains
jpayne@68 521 a further restriction but permits relicensing or conveying under this
jpayne@68 522 License, you may add to a covered work material governed by the terms
jpayne@68 523 of that license document, provided that the further restriction does
jpayne@68 524 not survive such relicensing or conveying.
jpayne@68 525 </p>
jpayne@68 526 <p>If you add terms to a covered work in accord with this section, you
jpayne@68 527 must place, in the relevant source files, a statement of the
jpayne@68 528 additional terms that apply to those files, or a notice indicating
jpayne@68 529 where to find the applicable terms.
jpayne@68 530 </p>
jpayne@68 531 <p>Additional terms, permissive or non-permissive, may be stated in the
jpayne@68 532 form of a separately written license, or stated as exceptions; the
jpayne@68 533 above requirements apply either way.
jpayne@68 534 </p>
jpayne@68 535 </li><li> Termination.
jpayne@68 536
jpayne@68 537 <p>You may not propagate or modify a covered work except as expressly
jpayne@68 538 provided under this License. Any attempt otherwise to propagate or
jpayne@68 539 modify it is void, and will automatically terminate your rights under
jpayne@68 540 this License (including any patent licenses granted under the third
jpayne@68 541 paragraph of section 11).
jpayne@68 542 </p>
jpayne@68 543 <p>However, if you cease all violation of this License, then your license
jpayne@68 544 from a particular copyright holder is reinstated (a) provisionally,
jpayne@68 545 unless and until the copyright holder explicitly and finally
jpayne@68 546 terminates your license, and (b) permanently, if the copyright holder
jpayne@68 547 fails to notify you of the violation by some reasonable means prior to
jpayne@68 548 60 days after the cessation.
jpayne@68 549 </p>
jpayne@68 550 <p>Moreover, your license from a particular copyright holder is
jpayne@68 551 reinstated permanently if the copyright holder notifies you of the
jpayne@68 552 violation by some reasonable means, this is the first time you have
jpayne@68 553 received notice of violation of this License (for any work) from that
jpayne@68 554 copyright holder, and you cure the violation prior to 30 days after
jpayne@68 555 your receipt of the notice.
jpayne@68 556 </p>
jpayne@68 557 <p>Termination of your rights under this section does not terminate the
jpayne@68 558 licenses of parties who have received copies or rights from you under
jpayne@68 559 this License. If your rights have been terminated and not permanently
jpayne@68 560 reinstated, you do not qualify to receive new licenses for the same
jpayne@68 561 material under section 10.
jpayne@68 562 </p>
jpayne@68 563 </li><li> Acceptance Not Required for Having Copies.
jpayne@68 564
jpayne@68 565 <p>You are not required to accept this License in order to receive or run
jpayne@68 566 a copy of the Program. Ancillary propagation of a covered work
jpayne@68 567 occurring solely as a consequence of using peer-to-peer transmission
jpayne@68 568 to receive a copy likewise does not require acceptance. However,
jpayne@68 569 nothing other than this License grants you permission to propagate or
jpayne@68 570 modify any covered work. These actions infringe copyright if you do
jpayne@68 571 not accept this License. Therefore, by modifying or propagating a
jpayne@68 572 covered work, you indicate your acceptance of this License to do so.
jpayne@68 573 </p>
jpayne@68 574 </li><li> Automatic Licensing of Downstream Recipients.
jpayne@68 575
jpayne@68 576 <p>Each time you convey a covered work, the recipient automatically
jpayne@68 577 receives a license from the original licensors, to run, modify and
jpayne@68 578 propagate that work, subject to this License. You are not responsible
jpayne@68 579 for enforcing compliance by third parties with this License.
jpayne@68 580 </p>
jpayne@68 581 <p>An &ldquo;entity transaction&rdquo; is a transaction transferring control of an
jpayne@68 582 organization, or substantially all assets of one, or subdividing an
jpayne@68 583 organization, or merging organizations. If propagation of a covered
jpayne@68 584 work results from an entity transaction, each party to that
jpayne@68 585 transaction who receives a copy of the work also receives whatever
jpayne@68 586 licenses to the work the party's predecessor in interest had or could
jpayne@68 587 give under the previous paragraph, plus a right to possession of the
jpayne@68 588 Corresponding Source of the work from the predecessor in interest, if
jpayne@68 589 the predecessor has it or can get it with reasonable efforts.
jpayne@68 590 </p>
jpayne@68 591 <p>You may not impose any further restrictions on the exercise of the
jpayne@68 592 rights granted or affirmed under this License. For example, you may
jpayne@68 593 not impose a license fee, royalty, or other charge for exercise of
jpayne@68 594 rights granted under this License, and you may not initiate litigation
jpayne@68 595 (including a cross-claim or counterclaim in a lawsuit) alleging that
jpayne@68 596 any patent claim is infringed by making, using, selling, offering for
jpayne@68 597 sale, or importing the Program or any portion of it.
jpayne@68 598 </p>
jpayne@68 599 </li><li> Patents.
jpayne@68 600
jpayne@68 601 <p>A &ldquo;contributor&rdquo; is a copyright holder who authorizes use under this
jpayne@68 602 License of the Program or a work on which the Program is based. The
jpayne@68 603 work thus licensed is called the contributor's &ldquo;contributor version&rdquo;.
jpayne@68 604 </p>
jpayne@68 605 <p>A contributor's &ldquo;essential patent claims&rdquo; are all patent claims owned
jpayne@68 606 or controlled by the contributor, whether already acquired or
jpayne@68 607 hereafter acquired, that would be infringed by some manner, permitted
jpayne@68 608 by this License, of making, using, or selling its contributor version,
jpayne@68 609 but do not include claims that would be infringed only as a
jpayne@68 610 consequence of further modification of the contributor version. For
jpayne@68 611 purposes of this definition, &ldquo;control&rdquo; includes the right to grant
jpayne@68 612 patent sublicenses in a manner consistent with the requirements of
jpayne@68 613 this License.
jpayne@68 614 </p>
jpayne@68 615 <p>Each contributor grants you a non-exclusive, worldwide, royalty-free
jpayne@68 616 patent license under the contributor's essential patent claims, to
jpayne@68 617 make, use, sell, offer for sale, import and otherwise run, modify and
jpayne@68 618 propagate the contents of its contributor version.
jpayne@68 619 </p>
jpayne@68 620 <p>In the following three paragraphs, a &ldquo;patent license&rdquo; is any express
jpayne@68 621 agreement or commitment, however denominated, not to enforce a patent
jpayne@68 622 (such as an express permission to practice a patent or covenant not to
jpayne@68 623 sue for patent infringement). To &ldquo;grant&rdquo; such a patent license to a
jpayne@68 624 party means to make such an agreement or commitment not to enforce a
jpayne@68 625 patent against the party.
jpayne@68 626 </p>
jpayne@68 627 <p>If you convey a covered work, knowingly relying on a patent license,
jpayne@68 628 and the Corresponding Source of the work is not available for anyone
jpayne@68 629 to copy, free of charge and under the terms of this License, through a
jpayne@68 630 publicly available network server or other readily accessible means,
jpayne@68 631 then you must either (1) cause the Corresponding Source to be so
jpayne@68 632 available, or (2) arrange to deprive yourself of the benefit of the
jpayne@68 633 patent license for this particular work, or (3) arrange, in a manner
jpayne@68 634 consistent with the requirements of this License, to extend the patent
jpayne@68 635 license to downstream recipients. &ldquo;Knowingly relying&rdquo; means you have
jpayne@68 636 actual knowledge that, but for the patent license, your conveying the
jpayne@68 637 covered work in a country, or your recipient's use of the covered work
jpayne@68 638 in a country, would infringe one or more identifiable patents in that
jpayne@68 639 country that you have reason to believe are valid.
jpayne@68 640 </p>
jpayne@68 641 <p>If, pursuant to or in connection with a single transaction or
jpayne@68 642 arrangement, you convey, or propagate by procuring conveyance of, a
jpayne@68 643 covered work, and grant a patent license to some of the parties
jpayne@68 644 receiving the covered work authorizing them to use, propagate, modify
jpayne@68 645 or convey a specific copy of the covered work, then the patent license
jpayne@68 646 you grant is automatically extended to all recipients of the covered
jpayne@68 647 work and works based on it.
jpayne@68 648 </p>
jpayne@68 649 <p>A patent license is &ldquo;discriminatory&rdquo; if it does not include within the
jpayne@68 650 scope of its coverage, prohibits the exercise of, or is conditioned on
jpayne@68 651 the non-exercise of one or more of the rights that are specifically
jpayne@68 652 granted under this License. You may not convey a covered work if you
jpayne@68 653 are a party to an arrangement with a third party that is in the
jpayne@68 654 business of distributing software, under which you make payment to the
jpayne@68 655 third party based on the extent of your activity of conveying the
jpayne@68 656 work, and under which the third party grants, to any of the parties
jpayne@68 657 who would receive the covered work from you, a discriminatory patent
jpayne@68 658 license (a) in connection with copies of the covered work conveyed by
jpayne@68 659 you (or copies made from those copies), or (b) primarily for and in
jpayne@68 660 connection with specific products or compilations that contain the
jpayne@68 661 covered work, unless you entered into that arrangement, or that patent
jpayne@68 662 license was granted, prior to 28 March 2007.
jpayne@68 663 </p>
jpayne@68 664 <p>Nothing in this License shall be construed as excluding or limiting
jpayne@68 665 any implied license or other defenses to infringement that may
jpayne@68 666 otherwise be available to you under applicable patent law.
jpayne@68 667 </p>
jpayne@68 668 </li><li> No Surrender of Others' Freedom.
jpayne@68 669
jpayne@68 670 <p>If conditions are imposed on you (whether by court order, agreement or
jpayne@68 671 otherwise) that contradict the conditions of this License, they do not
jpayne@68 672 excuse you from the conditions of this License. If you cannot convey
jpayne@68 673 a covered work so as to satisfy simultaneously your obligations under
jpayne@68 674 this License and any other pertinent obligations, then as a
jpayne@68 675 consequence you may not convey it at all. For example, if you agree
jpayne@68 676 to terms that obligate you to collect a royalty for further conveying
jpayne@68 677 from those to whom you convey the Program, the only way you could
jpayne@68 678 satisfy both those terms and this License would be to refrain entirely
jpayne@68 679 from conveying the Program.
jpayne@68 680 </p>
jpayne@68 681 </li><li> Use with the GNU Affero General Public License.
jpayne@68 682
jpayne@68 683 <p>Notwithstanding any other provision of this License, you have
jpayne@68 684 permission to link or combine any covered work with a work licensed
jpayne@68 685 under version 3 of the GNU Affero General Public License into a single
jpayne@68 686 combined work, and to convey the resulting work. The terms of this
jpayne@68 687 License will continue to apply to the part which is the covered work,
jpayne@68 688 but the special requirements of the GNU Affero General Public License,
jpayne@68 689 section 13, concerning interaction through a network will apply to the
jpayne@68 690 combination as such.
jpayne@68 691 </p>
jpayne@68 692 </li><li> Revised Versions of this License.
jpayne@68 693
jpayne@68 694 <p>The Free Software Foundation may publish revised and/or new versions
jpayne@68 695 of the GNU General Public License from time to time. Such new
jpayne@68 696 versions will be similar in spirit to the present version, but may
jpayne@68 697 differ in detail to address new problems or concerns.
jpayne@68 698 </p>
jpayne@68 699 <p>Each version is given a distinguishing version number. If the Program
jpayne@68 700 specifies that a certain numbered version of the GNU General Public
jpayne@68 701 License &ldquo;or any later version&rdquo; applies to it, you have the option of
jpayne@68 702 following the terms and conditions either of that numbered version or
jpayne@68 703 of any later version published by the Free Software Foundation. If
jpayne@68 704 the Program does not specify a version number of the GNU General
jpayne@68 705 Public License, you may choose any version ever published by the Free
jpayne@68 706 Software Foundation.
jpayne@68 707 </p>
jpayne@68 708 <p>If the Program specifies that a proxy can decide which future versions

jpayne@68 758
jpayne@68 759 <p>If you develop a new program, and you want it to be of the greatest
jpayne@68 760 possible use to the public, the best way to achieve this is to make it
jpayne@68 761 free software which everyone can redistribute and change under these
jpayne@68 762 terms.
jpayne@68 763 </p>
jpayne@68 764 <p>To do so, attach the following notices to the program. It is safest
jpayne@68 765 to attach them to the start of each source file to most effectively
jpayne@68 766 state the exclusion of warranty; and each file should have at least
jpayne@68 767 the &ldquo;copyright&rdquo; line and a pointer to where the full notice is found.

jpayne@68 830 PREAMBLE
jpayne@68 831
jpayne@68 832 <p>The purpose of this License is to make a manual, textbook, or other
jpayne@68 833 functional and useful document <em>free</em> in the sense of freedom: to
jpayne@68 834 assure everyone the effective freedom to copy and redistribute it,
jpayne@68 835 with or without modifying it, either commercially or noncommercially.
jpayne@68 836 Secondarily, this License preserves for the author and publisher a way
jpayne@68 837 to get credit for their work, while not being considered responsible
jpayne@68 838 for modifications made by others.
jpayne@68 839 </p>
jpayne@68 840 <p>This License is a kind of &ldquo;copyleft&rdquo;, which means that derivative
jpayne@68 841 works of the document must themselves be free in the same sense. It
jpayne@68 842 complements the GNU General Public License, which is a copyleft
jpayne@68 843 license designed for free software.
jpayne@68 844 </p>
jpayne@68 845 <p>We have designed this License in order to use it for manuals for free
jpayne@68 846 software, because free software needs free documentation: a free
jpayne@68 847 program should come with manuals providing the same freedoms that the
jpayne@68 848 software does. But this License is not limited to software manuals;
jpayne@68 849 it can be used for any textual work, regardless of subject matter or
jpayne@68 850 whether it is published as a printed book. We recommend this License
jpayne@68 851 principally for works whose purpose is instruction or reference.
jpayne@68 852 </p>
jpayne@68 853 </li><li>
jpayne@68 854 APPLICABILITY AND DEFINITIONS
jpayne@68 855
jpayne@68 856 <p>This License applies to any manual or other work, in any medium, that
jpayne@68 857 contains a notice placed by the copyright holder saying it can be
jpayne@68 858 distributed under the terms of this License. Such a notice grants a
jpayne@68 859 world-wide, royalty-free license, unlimited in duration, to use that
jpayne@68 860 work under the conditions stated herein. The &ldquo;Document&rdquo;, below,
jpayne@68 861 refers to any such manual or work. Any member of the public is a
jpayne@68 862 licensee, and is addressed as &ldquo;you&rdquo;. You accept the license if you
jpayne@68 863 copy, modify or distribute the work in a way requiring permission
jpayne@68 864 under copyright law.
jpayne@68 865 </p>
jpayne@68 866 <p>A &ldquo;Modified Version&rdquo; of the Document means any work containing the
jpayne@68 867 Document or a portion of it, either copied verbatim, or with
jpayne@68 868 modifications and/or translated into another language.
jpayne@68 869 </p>
jpayne@68 870 <p>A &ldquo;Secondary Section&rdquo; is a named appendix or a front-matter section
jpayne@68 871 of the Document that deals exclusively with the relationship of the
jpayne@68 872 publishers or authors of the Document to the Document's overall
jpayne@68 873 subject (or to related matters) and contains nothing that could fall
jpayne@68 874 directly within that overall subject. (Thus, if the Document is in
jpayne@68 875 part a textbook of mathematics, a Secondary Section may not explain
jpayne@68 876 any mathematics.) The relationship could be a matter of historical
jpayne@68 877 connection with the subject or with related matters, or of legal,
jpayne@68 878 commercial, philosophical, ethical or political position regarding
jpayne@68 879 them.
jpayne@68 880 </p>
jpayne@68 881 <p>The &ldquo;Invariant Sections&rdquo; are certain Secondary Sections whose titles
jpayne@68 882 are designated, as being those of Invariant Sections, in the notice
jpayne@68 883 that says that the Document is released under this License. If a
jpayne@68 884 section does not fit the above definition of Secondary then it is not
jpayne@68 885 allowed to be designated as Invariant. The Document may contain zero
jpayne@68 886 Invariant Sections. If the Document does not identify any Invariant
jpayne@68 887 Sections then there are none.
jpayne@68 888 </p>
jpayne@68 889 <p>The &ldquo;Cover Texts&rdquo; are certain short passages of text that are listed,
jpayne@68 890 as Front-Cover Texts or Back-Cover Texts, in the notice that says that
jpayne@68 891 the Document is released under this License. A Front-Cover Text may
jpayne@68 892 be at most 5 words, and a Back-Cover Text may be at most 25 words.
jpayne@68 893 </p>
jpayne@68 894 <p>A &ldquo;Transparent&rdquo; copy of the Document means a machine-readable copy,
jpayne@68 895 represented in a format whose specification is available to the
jpayne@68 896 general public, that is suitable for revising the document
jpayne@68 897 straightforwardly with generic text editors or (for images composed of
jpayne@68 898 pixels) generic paint programs or (for drawings) some widely available
jpayne@68 899 drawing editor, and that is suitable for input to text formatters or
jpayne@68 900 for automatic translation to a variety of formats suitable for input
jpayne@68 901 to text formatters. A copy made in an otherwise Transparent file
jpayne@68 902 format whose markup, or absence of markup, has been arranged to thwart
jpayne@68 903 or discourage subsequent modification by readers is not Transparent.
jpayne@68 904 An image format is not Transparent if used for any substantial amount
jpayne@68 905 of text. A copy that is not &ldquo;Transparent&rdquo; is called &ldquo;Opaque&rdquo;.
jpayne@68 906 </p>
jpayne@68 907 <p>Examples of suitable formats for Transparent copies include plain
jpayne@68 908 ASCII without markup, Texinfo input format, LaTeX input
jpayne@68 909 format, SGML or XML using a publicly available
jpayne@68 910 DTD, and standard-conforming simple HTML,
jpayne@68 911 PostScript or PDF designed for human modification. Examples
jpayne@68 912 of transparent image formats include PNG, XCF and
jpayne@68 913 JPG. Opaque formats include proprietary formats that can be
jpayne@68 914 read and edited only by proprietary word processors, SGML or
jpayne@68 915 XML for which the DTD and/or processing tools are
jpayne@68 916 not generally available, and the machine-generated HTML,
jpayne@68 917 PostScript or PDF produced by some word processors for
jpayne@68 918 output purposes only.
jpayne@68 919 </p>
jpayne@68 920 <p>The &ldquo;Title Page&rdquo; means, for a printed book, the title page itself,
jpayne@68 921 plus such following pages as are needed to hold, legibly, the material
jpayne@68 922 this License requires to appear in the title page. For works in
jpayne@68 923 formats which do not have any title page as such, &ldquo;Title Page&rdquo; means
jpayne@68 924 the text near the most prominent appearance of the work's title,
jpayne@68 925 preceding the beginning of the body of the text.
jpayne@68 926 </p>
jpayne@68 927 <p>The &ldquo;publisher&rdquo; means any person or entity that distributes copies
jpayne@68 928 of the Document to the public.
jpayne@68 929 </p>
jpayne@68 930 <p>A section &ldquo;Entitled XYZ&rdquo; means a named subunit of the Document whose
jpayne@68 931 title either is precisely XYZ or contains XYZ in parentheses following
jpayne@68 932 text that translates XYZ in another language. (Here XYZ stands for a
jpayne@68 933 specific section name mentioned below, such as &ldquo;Acknowledgements&rdquo;,
jpayne@68 934 &ldquo;Dedications&rdquo;, &ldquo;Endorsements&rdquo;, or &ldquo;History&rdquo;.) To &ldquo;Preserve the Title&rdquo;
jpayne@68 935 of such a section when you modify the Document means that it remains a
jpayne@68 936 section &ldquo;Entitled XYZ&rdquo; according to this definition.
jpayne@68 937 </p>
jpayne@68 938 <p>The Document may include Warranty Disclaimers next to the notice which
jpayne@68 939 states that this License applies to the Document. These Warranty
jpayne@68 940 Disclaimers are considered to be included by reference in this
jpayne@68 941 License, but only as regards disclaiming warranties: any other
jpayne@68 942 implication that these Warranty Disclaimers may have is void and has
jpayne@68 943 no effect on the meaning of this License.
jpayne@68 944 </p>
jpayne@68 945 </li><li>
jpayne@68 946 VERBATIM COPYING
jpayne@68 947
jpayne@68 948 <p>You may copy and distribute the Document in any medium, either
jpayne@68 949 commercially or noncommercially, provided that this License, the
jpayne@68 950 copyright notices, and the license notice saying this License applies
jpayne@68 951 to the Document are reproduced in all copies, and that you add no other
jpayne@68 952 conditions whatsoever to those of this License. You may not use
jpayne@68 953 technical measures to obstruct or control the reading or further
jpayne@68 954 copying of the copies you make or distribute. However, you may accept
jpayne@68 955 compensation in exchange for copies. If you distribute a large enough
jpayne@68 956 number of copies you must also follow the conditions in section 3.
jpayne@68 957 </p>
jpayne@68 958 <p>You may also lend copies, under the same conditions stated above, and
jpayne@68 959 you may publicly display copies.
jpayne@68 960 </p>
jpayne@68 961 </li><li>
jpayne@68 962 COPYING IN QUANTITY
jpayne@68 963
jpayne@68 964 <p>If you publish printed copies (or copies in media that commonly have
jpayne@68 965 printed covers) of the Document, numbering more than 100, and the
jpayne@68 966 Document's license notice requires Cover Texts, you must enclose the
jpayne@68 967 copies in covers that carry, clearly and legibly, all these Cover
jpayne@68 968 Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
jpayne@68 969 the back cover. Both covers must also clearly and legibly identify
jpayne@68 970 you as the publisher of these copies. The front cover must present
jpayne@68 971 the full title with all words of the title equally prominent and
jpayne@68 972 visible. You may add other material on the covers in addition.
jpayne@68 973 Copying with changes limited to the covers, as long as they preserve
jpayne@68 974 the title of the Document and satisfy these conditions, can be treated
jpayne@68 975 as verbatim copying in other respects.
jpayne@68 976 </p>
jpayne@68 977 <p>If the required texts for either cover are too voluminous to fit
jpayne@68 978 legibly, you should put the first ones listed (as many as fit
jpayne@68 979 reasonably) on the actual cover, and continue the rest onto adjacent
jpayne@68 980 pages.
jpayne@68 981 </p>
jpayne@68 982 <p>If you publish or distribute Opaque copies of the Document numbering
jpayne@68 983 more than 100, you must either include a machine-readable Transparent
jpayne@68 984 copy along with each Opaque copy, or state in or with each Opaque copy
jpayne@68 985 a computer-network location from which the general network-using
jpayne@68 986 public has access to download using public-standard network protocols
jpayne@68 987 a complete Transparent copy of the Document, free of added material.
jpayne@68 988 If you use the latter option, you must take reasonably prudent steps,
jpayne@68 989 when you begin distribution of Opaque copies in quantity, to ensure
jpayne@68 990 that this Transparent copy will remain thus accessible at the stated
jpayne@68 991 location until at least one year after the last time you distribute an
jpayne@68 992 Opaque copy (directly or through your agents or retailers) of that
jpayne@68 993 edition to the public.
jpayne@68 994 </p>
jpayne@68 995 <p>It is requested, but not required, that you contact the authors of the
jpayne@68 996 Document well before redistributing any large number of copies, to give
jpayne@68 997 them a chance to provide you with an updated version of the Document.
jpayne@68 998 </p>
jpayne@68 999 </li><li>
jpayne@68 1000 MODIFICATIONS
jpayne@68 1001
jpayne@68 1002 <p>You may copy and distribute a Modified Version of the Document under
jpayne@68 1003 the conditions of sections 2 and 3 above, provided that you release
jpayne@68 1004 the Modified Version under precisely this License, with the Modified
jpayne@68 1005 Version filling the role of the Document, thus licensing distribution
jpayne@68 1006 and modification of the Modified Version to whoever possesses a copy
jpayne@68 1007 of it. In addition, you must do these things in the Modified Version:
jpayne@68 1008 </p>
jpayne@68 1009 <ol>
jpayne@68 1010 <li>
jpayne@68 1011 Use in the Title Page (and on the covers, if any) a title distinct
jpayne@68 1012 from that of the Document, and from those of previous versions
jpayne@68 1013 (which should, if there were any, be listed in the History section
jpayne@68 1014 of the Document). You may use the same title as a previous version
jpayne@68 1015 if the original publisher of that version gives permission.
jpayne@68 1016
jpayne@68 1017 </li><li>
jpayne@68 1018 List on the Title Page, as authors, one or more persons or entities
jpayne@68 1019 responsible for authorship of the modifications in the Modified
jpayne@68 1020 Version, together with at least five of the principal authors of the
jpayne@68 1021 Document (all of its principal authors, if it has fewer than five),
jpayne@68 1022 unless they release you from this requirement.
jpayne@68 1023
jpayne@68 1024 </li><li>
jpayne@68 1025 State on the Title page the name of the publisher of the
jpayne@68 1026 Modified Version, as the publisher.
jpayne@68 1027
jpayne@68 1028 </li><li>
jpayne@68 1029 Preserve all the copyright notices of the Document.
jpayne@68 1030
jpayne@68 1031 </li><li>
jpayne@68 1032 Add an appropriate copyright notice for your modifications
jpayne@68 1033 adjacent to the other copyright notices.
jpayne@68 1034
jpayne@68 1035 </li><li>
jpayne@68 1036 Include, immediately after the copyright notices, a license notice
jpayne@68 1037 giving the public permission to use the Modified Version under the
jpayne@68 1038 terms of this License, in the form shown in the Addendum below.
jpayne@68 1039
jpayne@68 1040 </li><li>
jpayne@68 1041 Preserve in that license notice the full lists of Invariant Sections
jpayne@68 1042 and required Cover Texts given in the Document's license notice.
jpayne@68 1043
jpayne@68 1044 </li><li>
jpayne@68 1045 Include an unaltered copy of this License.
jpayne@68 1046
jpayne@68 1047 </li><li>
jpayne@68 1048 Preserve the section Entitled &ldquo;History&rdquo;, Preserve its Title, and add
jpayne@68 1049 to it an item stating at least the title, year, new authors, and
jpayne@68 1050 publisher of the Modified Version as given on the Title Page. If
jpayne@68 1051 there is no section Entitled &ldquo;History&rdquo; in the Document, create one
jpayne@68 1052 stating the title, year, authors, and publisher of the Document as
jpayne@68 1053 given on its Title Page, then add an item describing the Modified
jpayne@68 1054 Version as stated in the previous sentence.
jpayne@68 1055
jpayne@68 1056 </li><li>
jpayne@68 1057 Preserve the network location, if any, given in the Document for

jpayne@68 1059 the network locations given in the Document for previous versions
jpayne@68 1060 it was based on. These may be placed in the &ldquo;History&rdquo; section.
jpayne@68 1061 You may omit a network location for a work that was published at
jpayne@68 1062 least four years before the Document itself, or if the original
jpayne@68 1063 publisher of the version it refers to gives permission.

jpayne@68 1065 </li><li>
jpayne@68 1066 For any section Entitled &ldquo;Acknowledgements&rdquo; or &ldquo;Dedications&rdquo;, Preserve
jpayne@68 1067 the Title of the section, and preserve in the section all the
jpayne@68 1068 substance and tone of each of the contributor acknowledgements and/or
jpayne@68 1069 dedications given therein.
jpayne@68 1070
jpayne@68 1071 </li><li>
jpayne@68 1072 Preserve all the Invariant Sections of the Document,
jpayne@68 1073 unaltered in their text and in their titles. Section numbers
jpayne@68 1074 or the equivalent are not considered part of the section titles.
jpayne@68 1075
jpayne@68 1076 </li><li>
jpayne@68 1077 Delete any section Entitled &ldquo;Endorsements&rdquo;. Such a section
jpayne@68 1078 may not be included in the Modified Version.
jpayne@68 1079
jpayne@68 1080 </li><li>
jpayne@68 1081 Do not retitle any existing section to be Entitled &ldquo;Endorsements&rdquo; or

jpayne@68 1083
jpayne@68 1084 </li><li>
jpayne@68 1085 Preserve any Warranty Disclaimers.
jpayne@68 1086 </li></ol>
jpayne@68 1087
jpayne@68 1088 <p>If the Modified Version includes new front-matter sections or
jpayne@68 1089 appendices that qualify as Secondary Sections and contain no material
jpayne@68 1090 copied from the Document, you may at your option designate some or all
jpayne@68 1091 of these sections as invariant. To do this, add their titles to the
jpayne@68 1092 list of Invariant Sections in the Modified Version's license notice.
jpayne@68 1093 These titles must be distinct from any other section titles.
jpayne@68 1094 </p>
jpayne@68 1095 <p>You may add a section Entitled &ldquo;Endorsements&rdquo;, provided it contains
jpayne@68 1096 nothing but endorsements of your Modified Version by various
jpayne@68 1097 parties&mdash;for example, statements of peer review or that the text has
jpayne@68 1098 been approved by an organization as the authoritative definition of a
jpayne@68 1099 standard.
jpayne@68 1100 </p>
jpayne@68 1101 <p>You may add a passage of up to five words as a Front-Cover Text, and a
jpayne@68 1102 passage of up to 25 words as a Back-Cover Text, to the end of the list
jpayne@68 1103 of Cover Texts in the Modified Version. Only one passage of
jpayne@68 1104 Front-Cover Text and one of Back-Cover Text may be added by (or
jpayne@68 1105 through arrangements made by) any one entity. If the Document already
jpayne@68 1106 includes a cover text for the same cover, previously added by you or
jpayne@68 1107 by arrangement made by the same entity you are acting on behalf of,
jpayne@68 1108 you may not add another; but you may replace the old one, on explicit
jpayne@68 1109 permission from the previous publisher that added the old one.
jpayne@68 1110 </p>
jpayne@68 1111 <p>The author(s) and publisher(s) of the Document do not by this License
jpayne@68 1112 give permission to use their names for publicity for or to assert or
jpayne@68 1113 imply endorsement of any Modified Version.
jpayne@68 1114 </p>
jpayne@68 1115 </li><li>
jpayne@68 1116 COMBINING DOCUMENTS
jpayne@68 1117
jpayne@68 1118 <p>You may combine the Document with other documents released under this
jpayne@68 1119 License, under the terms defined in section 4 above for modified
jpayne@68 1120 versions, provided that you include in the combination all of the
jpayne@68 1121 Invariant Sections of all of the original documents, unmodified, and
jpayne@68 1122 list them all as Invariant Sections of your combined work in its
jpayne@68 1123 license notice, and that you preserve all their Warranty Disclaimers.
jpayne@68 1124 </p>
jpayne@68 1125 <p>The combined work need only contain one copy of this License, and
jpayne@68 1126 multiple identical Invariant Sections may be replaced with a single
jpayne@68 1127 copy. If there are multiple Invariant Sections with the same name but
jpayne@68 1128 different contents, make the title of each such section unique by
jpayne@68 1129 adding at the end of it, in parentheses, the name of the original
jpayne@68 1130 author or publisher of that section if known, or else a unique number.
jpayne@68 1131 Make the same adjustment to the section titles in the list of
jpayne@68 1132 Invariant Sections in the license notice of the combined work.
jpayne@68 1133 </p>
jpayne@68 1134 <p>In the combination, you must combine any sections Entitled &ldquo;History&rdquo;
jpayne@68 1135 in the various original documents, forming one section Entitled
jpayne@68 1136 &ldquo;History&rdquo;; likewise combine any sections Entitled &ldquo;Acknowledgements&rdquo;,
jpayne@68 1137 and any sections Entitled &ldquo;Dedications&rdquo;. You must delete all
jpayne@68 1138 sections Entitled &ldquo;Endorsements.&rdquo;
jpayne@68 1139 </p>
jpayne@68 1140 </li><li>
jpayne@68 1141 COLLECTIONS OF DOCUMENTS
jpayne@68 1142
jpayne@68 1143 <p>You may make a collection consisting of the Document and other documents
jpayne@68 1144 released under this License, and replace the individual copies of this
jpayne@68 1145 License in the various documents with a single copy that is included in
jpayne@68 1146 the collection, provided that you follow the rules of this License for
jpayne@68 1147 verbatim copying of each of the documents in all other respects.
jpayne@68 1148 </p>
jpayne@68 1149 <p>You may extract a single document from such a collection, and distribute
jpayne@68 1150 it individually under this License, provided you insert a copy of this
jpayne@68 1151 License into the extracted document, and follow this License in all
jpayne@68 1152 other respects regarding verbatim copying of that document.
jpayne@68 1153 </p>
jpayne@68 1154 </li><li>
jpayne@68 1155 AGGREGATION WITH INDEPENDENT WORKS
jpayne@68 1156
jpayne@68 1157 <p>A compilation of the Document or its derivatives with other separate
jpayne@68 1158 and independent documents or works, in or on a volume of a storage or
jpayne@68 1159 distribution medium, is called an &ldquo;aggregate&rdquo; if the copyright
jpayne@68 1160 resulting from the compilation is not used to limit the legal rights
jpayne@68 1161 of the compilation's users beyond what the individual works permit.
jpayne@68 1162 When the Document is included in an aggregate, this License does not
jpayne@68 1163 apply to the other works in the aggregate which are not themselves
jpayne@68 1164 derivative works of the Document.
jpayne@68 1165 </p>
jpayne@68 1166 <p>If the Cover Text requirement of section 3 is applicable to these
jpayne@68 1167 copies of the Document, then if the Document is less than one half of
jpayne@68 1168 the entire aggregate, the Document's Cover Texts may be placed on
jpayne@68 1169 covers that bracket the Document within the aggregate, or the
jpayne@68 1170 electronic equivalent of covers if the Document is in electronic form.
jpayne@68 1171 Otherwise they must appear on printed covers that bracket the whole
jpayne@68 1172 aggregate.
jpayne@68 1173 </p>
jpayne@68 1174 </li><li>
jpayne@68 1175 TRANSLATION
jpayne@68 1176
jpayne@68 1177 <p>Translation is considered a kind of modification, so you may
jpayne@68 1178 distribute translations of the Document under the terms of section 4.
jpayne@68 1179 Replacing Invariant Sections with translations requires special
jpayne@68 1180 permission from their copyright holders, but you may include
jpayne@68 1181 translations of some or all Invariant Sections in addition to the
jpayne@68 1182 original versions of these Invariant Sections. You may include a
jpayne@68 1183 translation of this License, and all the license notices in the
jpayne@68 1184 Document, and any Warranty Disclaimers, provided that you also include
jpayne@68 1185 the original English version of this License and the original versions
jpayne@68 1186 of those notices and disclaimers. In case of a disagreement between
jpayne@68 1187 the translation and the original version of this License or a notice
jpayne@68 1188 or disclaimer, the original version will prevail.
jpayne@68 1189 </p>
jpayne@68 1190 <p>If a section in the Document is Entitled &ldquo;Acknowledgements&rdquo;,
jpayne@68 1191 &ldquo;Dedications&rdquo;, or &ldquo;History&rdquo;, the requirement (section 4) to Preserve
jpayne@68 1192 its Title (section 1) will typically require changing the actual
jpayne@68 1193 title.
jpayne@68 1194 </p>
jpayne@68 1195 </li><li>
jpayne@68 1196 TERMINATION
jpayne@68 1197
jpayne@68 1198 <p>You may not copy, modify, sublicense, or distribute the Document
jpayne@68 1199 except as expressly provided under this License. Any attempt
jpayne@68 1200 otherwise to copy, modify, sublicense, or distribute it is void, and
jpayne@68 1201 will automatically terminate your rights under this License.
jpayne@68 1202 </p>
jpayne@68 1203 <p>However, if you cease all violation of this License, then your license
jpayne@68 1204 from a particular copyright holder is reinstated (a) provisionally,
jpayne@68 1205 unless and until the copyright holder explicitly and finally
jpayne@68 1206 terminates your license, and (b) permanently, if the copyright holder
jpayne@68 1207 fails to notify you of the violation by some reasonable means prior to
jpayne@68 1208 60 days after the cessation.
jpayne@68 1209 </p>
jpayne@68 1210 <p>Moreover, your license from a particular copyright holder is
jpayne@68 1211 reinstated permanently if the copyright holder notifies you of the
jpayne@68 1212 violation by some reasonable means, this is the first time you have
jpayne@68 1213 received notice of violation of this License (for any work) from that
jpayne@68 1214 copyright holder, and you cure the violation prior to 30 days after
jpayne@68 1215 your receipt of the notice.
jpayne@68 1216 </p>
jpayne@68 1217 <p>Termination of your rights under this section does not terminate the
jpayne@68 1218 licenses of parties who have received copies or rights from you under
jpayne@68 1219 this License. If your rights have been terminated and not permanently
jpayne@68 1220 reinstated, receipt of a copy of some or all of the same material does
jpayne@68 1221 not give you any rights to use it.
jpayne@68 1222 </p>

jpayne@68 1224 FUTURE REVISIONS OF THIS LICENSE
jpayne@68 1225
jpayne@68 1226 <p>The Free Software Foundation may publish new, revised versions
jpayne@68 1227 of the GNU Free Documentation License from time to time. Such new
jpayne@68 1228 versions will be similar in spirit to the present version, but may
jpayne@68 1229 differ in detail to address new problems or concerns. See
jpayne@68 1230 <a href="https://www.gnu.org/copyleft/">https://www.gnu.org/copyleft/</a>.
jpayne@68 1231 </p>
jpayne@68 1232 <p>Each version of the License is given a distinguishing version number.
jpayne@68 1233 If the Document specifies that a particular numbered version of this
jpayne@68 1234 License &ldquo;or any later version&rdquo; applies to it, you have the option of
jpayne@68 1235 following the terms and conditions either of that specified version or
jpayne@68 1236 of any later version that has been published (not as a draft) by the
jpayne@68 1237 Free Software Foundation. If the Document does not specify a version
jpayne@68 1238 number of this License, you may choose any version ever published (not
jpayne@68 1239 as a draft) by the Free Software Foundation. If the Document
jpayne@68 1240 specifies that a proxy can decide which future versions of this
jpayne@68 1241 License can be used, that proxy's public statement of acceptance of a
jpayne@68 1242 version permanently authorizes you to choose that version for the
jpayne@68 1243 Document.

jpayne@68 1245 </li><li>
jpayne@68 1246 RELICENSING
jpayne@68 1247
jpayne@68 1248 <p>&ldquo;Massive Multiauthor Collaboration Site&rdquo; (or &ldquo;MMC Site&rdquo;) means any
jpayne@68 1249 World Wide Web server that publishes copyrightable works and also
jpayne@68 1250 provides prominent facilities for anybody to edit those works. A
jpayne@68 1251 public wiki that anybody can edit is an example of such a server. A
jpayne@68 1252 &ldquo;Massive Multiauthor Collaboration&rdquo; (or &ldquo;MMC&rdquo;) contained in the
jpayne@68 1253 site means any set of copyrightable works thus published on the MMC
jpayne@68 1254 site.
jpayne@68 1255 </p>
jpayne@68 1256 <p>&ldquo;CC-BY-SA&rdquo; means the Creative Commons Attribution-Share Alike 3.0
jpayne@68 1257 license published by Creative Commons Corporation, a not-for-profit
jpayne@68 1258 corporation with a principal place of business in San Francisco,
jpayne@68 1259 California, as well as future copyleft versions of that license
jpayne@68 1260 published by that same organization.
jpayne@68 1261 </p>
jpayne@68 1262 <p>&ldquo;Incorporate&rdquo; means to publish or republish a Document, in whole or
jpayne@68 1263 in part, as part of another Document.
jpayne@68 1264 </p>
jpayne@68 1265 <p>An MMC is &ldquo;eligible for relicensing&rdquo; if it is licensed under this
jpayne@68 1266 License, and if all works that were first published under this License
jpayne@68 1267 somewhere other than this MMC, and subsequently incorporated in whole
jpayne@68 1268 or in part into the MMC, (1) had no cover texts or invariant sections,
jpayne@68 1269 and (2) were thus incorporated prior to November 1, 2008.
jpayne@68 1270 </p>
jpayne@68 1271 <p>The operator of an MMC Site may republish an MMC contained in the site
jpayne@68 1272 under CC-BY-SA on the same site at any time before August 1, 2009,
jpayne@68 1273 provided the MMC is eligible for relicensing.

jpayne@68 1280
jpayne@68 1281 <p>To use this License in a document you have written, include a copy of
jpayne@68 1282 the License in the document and put the following copyright and
jpayne@68 1283 license notices just after the title page:
