|

| 24 | <p>
|
|---|
| 25 | The purpose of this License is to make a manual, textbook, or other
|
|---|
| 26 | functional and useful document "free" in the sense of freedom: to
|
|---|
| 27 | assure everyone the effective freedom to copy and redistribute it,
|
|---|
| 28 | with or without modifying it, either commercially or noncommercially.
|
|---|
| 29 | Secondarily, this License preserves for the author and publisher a way
|
|---|
| 30 | to get credit for their work, while not being considered responsible
|
|---|
| 31 | for modifications made by others.
|
|---|
| 32 | </p>
|
|---|
| 33 |
|
|---|
| 34 | <p>
|
|---|
| 35 |
|
|---|
| 36 | This License is a kind of "copyleft", which means that derivative
|
|---|
| 37 | works of the document must themselves be free in the same sense. It
|
|---|
| 38 | complements the GNU General Public License, which is a copyleft
|
|---|
| 39 | license designed for free software.
|
|---|
| 40 | </p>
|
|---|
| 41 |
|
|---|
| 42 | <p>
|
|---|
| 43 | We have designed this License in order to use it for manuals for free
|
|---|
| 44 | software, because free software needs free documentation: a free
|
|---|
| 45 | program should come with manuals providing the same freedoms that the
|
|---|
| 46 | software does. But this License is not limited to software manuals;
|
|---|
| 47 | it can be used for any textual work, regardless of subject matter or
|
|---|
| 48 | whether it is published as a printed book. We recommend this License
|
|---|
| 49 | principally for works whose purpose is instruction or reference.

| 53 | <strong>1. APPLICABILITY AND DEFINITIONS</strong>
|
|---|
| 54 | </p>
|
|---|
| 55 |
|
|---|
| 56 | <p>
|
|---|
| 57 |
|
|---|
| 58 | This License applies to any manual or other work, in any medium, that
|
|---|
| 59 | contains a notice placed by the copyright holder saying it can be
|
|---|
| 60 | distributed under the terms of this License. Such a notice grants a
|
|---|
| 61 | world-wide, royalty-free license, unlimited in duration, to use that
|
|---|
| 62 | work under the conditions stated herein. The "Document", below,
|
|---|
| 63 | refers to any such manual or work. Any member of the public is a
|
|---|
| 64 | licensee, and is addressed as "you". You accept the license if you
|
|---|
| 65 | copy, modify or distribute the work in a way requiring permission
|
|---|
| 66 | under copyright law.
|
|---|
| 67 | </p>
|
|---|
| 68 |
|
|---|
| 69 | <p>
|
|---|
| 70 | A "Modified Version" of the Document means any work containing the
|
|---|
| 71 | Document or a portion of it, either copied verbatim, or with
|
|---|
| 72 | modifications and/or translated into another language.
|
|---|
| 73 | </p>
|
|---|
| 74 |
|
|---|
| 75 | <p>
|
|---|
| 76 | A "Secondary Section" is a named appendix or a front-matter section of
|
|---|
| 77 | the Document that deals exclusively with the relationship of the
|
|---|
| 78 | publishers or authors of the Document to the Document's overall subject
|
|---|
| 79 | (or to related matters) and contains nothing that could fall directly
|
|---|
| 80 | within that overall subject. (Thus, if the Document is in part a
|
|---|
| 81 | textbook of mathematics, a Secondary Section may not explain any
|
|---|
| 82 | mathematics.) The relationship could be a matter of historical
|
|---|
| 83 | connection with the subject or with related matters, or of legal,
|
|---|
| 84 | commercial, philosophical, ethical or political position regarding
|
|---|
| 85 | them.
|
|---|
| 86 | </p>
|
|---|
| 87 |
|
|---|
| 88 | <p>
|
|---|
| 89 | The "Invariant Sections" are certain Secondary Sections whose titles
|
|---|
| 90 | are designated, as being those of Invariant Sections, in the notice
|
|---|
| 91 | that says that the Document is released under this License. If a
|
|---|
| 92 | section does not fit the above definition of Secondary then it is not
|
|---|
| 93 | allowed to be designated as Invariant. The Document may contain zero
|
|---|
| 94 | Invariant Sections. If the Document does not identify any Invariant
|
|---|
| 95 | Sections then there are none.
|
|---|
| 96 |
|
|---|
| 97 | </p>
|
|---|
| 98 |
|
|---|
| 99 | <p>
|
|---|
| 100 | The "Cover Texts" are certain short passages of text that are listed,
|
|---|
| 101 | as Front-Cover Texts or Back-Cover Texts, in the notice that says that
|
|---|
| 102 | the Document is released under this License. A Front-Cover Text may
|
|---|
| 103 | be at most 5 words, and a Back-Cover Text may be at most 25 words.
|
|---|
| 104 | </p>
|
|---|
| 105 |
|
|---|
| 106 | <p>
|
|---|
| 107 | A "Transparent" copy of the Document means a machine-readable copy,
|
|---|
| 108 | represented in a format whose specification is available to the
|
|---|
| 109 | general public, that is suitable for revising the document
|
|---|
| 110 | straightforwardly with generic text editors or (for images composed of
|
|---|
| 111 | pixels) generic paint programs or (for drawings) some widely available
|
|---|
| 112 | drawing editor, and that is suitable for input to text formatters or
|
|---|
| 113 | for automatic translation to a variety of formats suitable for input
|
|---|
| 114 | to text formatters. A copy made in an otherwise Transparent file
|
|---|
| 115 | format whose markup, or absence of markup, has been arranged to thwart
|
|---|
| 116 | or discourage subsequent modification by readers is not Transparent.
|
|---|
| 117 | An image format is not Transparent if used for any substantial amount
|
|---|
| 118 | of text. A copy that is not "Transparent" is called "Opaque".
|
|---|
| 119 | </p>
|
|---|
| 120 |
|
|---|
| 121 | <p>
|
|---|
| 122 | Examples of suitable formats for Transparent copies include plain
|
|---|
| 123 | ASCII without markup, Texinfo input format, LaTeX input format, SGML
|
|---|
| 124 | or XML using a publicly available DTD, and standard-conforming simple
|
|---|
| 125 | HTML, PostScript or PDF designed for human modification. Examples of
|
|---|
| 126 | transparent image formats include PNG, XCF and JPG. Opaque formats
|
|---|
| 127 | include proprietary formats that can be read and edited only by
|
|---|
| 128 | proprietary word processors, SGML or XML for which the DTD and/or
|
|---|
| 129 | processing tools are not generally available, and the
|
|---|
| 130 | machine-generated HTML, PostScript or PDF produced by some word
|
|---|
| 131 | processors for output purposes only.
|
|---|
| 132 | </p>
|
|---|
| 133 |
|
|---|
| 134 | <p>
|
|---|
| 135 | The "Title Page" means, for a printed book, the title page itself,
|
|---|
| 136 | plus such following pages as are needed to hold, legibly, the material
|
|---|
| 137 | this License requires to appear in the title page. For works in
|
|---|
| 138 | formats which do not have any title page as such, "Title Page" means
|
|---|
| 139 | the text near the most prominent appearance of the work's title,
|
|---|
| 140 | preceding the beginning of the body of the text.
|
|---|
| 141 | </p>
|
|---|
| 142 |
|
|---|
| 143 | <p>
|
|---|
| 144 | A section "Entitled XYZ" means a named subunit of the Document whose
|
|---|
| 145 | title either is precisely XYZ or contains XYZ in parentheses following
|
|---|
| 146 | text that translates XYZ in another language. (Here XYZ stands for a
|
|---|
| 147 | specific section name mentioned below, such as "Acknowledgements",
|
|---|
| 148 | "Dedications", "Endorsements", or "History".) To "Preserve the Title"
|
|---|
| 149 | of such a section when you modify the Document means that it remains a
|
|---|
| 150 | section "Entitled XYZ" according to this definition.
|
|---|
| 151 | </p>
|
|---|
| 152 |
|
|---|
| 153 | <p>
|
|---|
| 154 | The Document may include Warranty Disclaimers next to the notice which
|
|---|
| 155 | states that this License applies to the Document. These Warranty
|
|---|
| 156 | Disclaimers are considered to be included by reference in this
|
|---|
| 157 | License, but only as regards disclaiming warranties: any other
|
|---|
| 158 | implication that these Warranty Disclaimers may have is void and has
|
|---|
| 159 | no effect on the meaning of this License.
|
|---|
| 160 | </p>

|
|---|
| 164 | <strong>2. VERBATIM COPYING</strong>
|
|---|
| 165 | </p>
|
|---|
| 166 |
|
|---|
| 167 | <p>
|
|---|
| 168 | You may copy and distribute the Document in any medium, either
|
|---|
| 169 | commercially or noncommercially, provided that this License, the
|
|---|
| 170 | copyright notices, and the license notice saying this License applies
|
|---|
| 171 | to the Document are reproduced in all copies, and that you add no other
|
|---|
| 172 | conditions whatsoever to those of this License. You may not use
|
|---|
| 173 | technical measures to obstruct or control the reading or further
|
|---|
| 174 | copying of the copies you make or distribute. However, you may accept
|
|---|
| 175 | compensation in exchange for copies. If you distribute a large enough
|
|---|
| 176 | number of copies you must also follow the conditions in section 3.
|
|---|
| 177 | </p>
|
|---|
| 178 |
|
|---|
| 179 | <p>
|
|---|
| 180 | You may also lend copies, under the same conditions stated above, and
|
|---|
| 181 | you may publicly display copies.
|
|---|
| 182 | </p>
|
|---|
| 183 |
|
|---|
| 184 | <p>
|
|---|
| 185 |
|
|---|
| 186 | <strong>3. COPYING IN QUANTITY</strong>
|
|---|
| 187 | </p>
|
|---|
| 188 |
|
|---|
| 189 | <p>
|
|---|
| 190 | If you publish printed copies (or copies in media that commonly have
|
|---|
| 191 | printed covers) of the Document, numbering more than 100, and the
|
|---|
| 192 | Document's license notice requires Cover Texts, you must enclose the
|
|---|
| 193 | copies in covers that carry, clearly and legibly, all these Cover
|
|---|
| 194 | Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
|
|---|
| 195 | the back cover. Both covers must also clearly and legibly identify
|
|---|
| 196 | you as the publisher of these copies. The front cover must present
|
|---|
| 197 | the full title with all words of the title equally prominent and
|
|---|
| 198 | visible. You may add other material on the covers in addition.
|
|---|
| 199 | Copying with changes limited to the covers, as long as they preserve
|
|---|
| 200 | the title of the Document and satisfy these conditions, can be treated
|
|---|
| 201 | as verbatim copying in other respects.
|
|---|
| 202 | </p>
|
|---|
| 203 |
|
|---|
| 204 | <p>
|
|---|
| 205 | If the required texts for either cover are too voluminous to fit
|
|---|
| 206 | legibly, you should put the first ones listed (as many as fit
|
|---|
| 207 | reasonably) on the actual cover, and continue the rest onto adjacent
|
|---|
| 208 | pages.
|
|---|
| 209 | </p>
|
|---|
| 210 |
|
|---|
| 211 | <p>
|
|---|
| 212 | If you publish or distribute Opaque copies of the Document numbering
|
|---|
| 213 | more than 100, you must either include a machine-readable Transparent
|
|---|
| 214 | copy along with each Opaque copy, or state in or with each Opaque copy
|
|---|
| 215 | a computer-network location from which the general network-using
|
|---|
| 216 | public has access to download using public-standard network protocols
|
|---|
| 217 | a complete Transparent copy of the Document, free of added material.
|
|---|
| 218 | If you use the latter option, you must take reasonably prudent steps,
|
|---|
| 219 | when you begin distribution of Opaque copies in quantity, to ensure
|
|---|
| 220 | that this Transparent copy will remain thus accessible at the stated
|
|---|
| 221 | location until at least one year after the last time you distribute an
|
|---|
| 222 | Opaque copy (directly or through your agents or retailers) of that
|
|---|
| 223 | edition to the public.
|
|---|
| 224 | </p>
|
|---|
| 225 |
|
|---|
| 226 | <p>
|
|---|
| 227 | It is requested, but not required, that you contact the authors of the
|
|---|
| 228 | Document well before redistributing any large number of copies, to give
|
|---|
| 229 | them a chance to provide you with an updated version of the Document.
|
|---|
| 230 | </p>
|
|---|
| 231 |
|
|---|
| 232 | <p>
|
|---|
| 233 | <strong>4. MODIFICATIONS</strong>
|
|---|
| 234 | </p>
|
|---|
| 235 |
|
|---|
| 236 | <p>
|
|---|
| 237 |
|
|---|
| 238 | You may copy and distribute a Modified Version of the Document under
|
|---|
| 239 | the conditions of sections 2 and 3 above, provided that you release
|
|---|
| 240 | the Modified Version under precisely this License, with the Modified
|
|---|
| 241 | Version filling the role of the Document, thus licensing distribution
|
|---|
| 242 | and modification of the Modified Version to whoever possesses a copy
|
|---|
| 243 | of it. In addition, you must do these things in the Modified Version:
|
|---|
| 244 | </p>
|
|---|
| 245 |
|
|---|
| 246 | <ul>
|
|---|
| 247 | <li><strong>A.</strong> Use in the Title Page (and on the covers, if any) a title distinct
|
|---|
| 248 | from that of the Document, and from those of previous versions
|
|---|
| 249 | (which should, if there were any, be listed in the History section
|
|---|
| 250 | of the Document). You may use the same title as a previous version
|
|---|
| 251 | if the original publisher of that version gives permission.</li>
|
|---|
| 252 | <li><strong>B.</strong> List on the Title Page, as authors, one or more persons or entities
|
|---|
| 253 | responsible for authorship of the modifications in the Modified
|
|---|
| 254 | Version, together with at least five of the principal authors of the
|
|---|
| 255 | Document (all of its principal authors, if it has fewer than five),
|
|---|
| 256 | unless they release you from this requirement.</li>
|
|---|
| 257 |
|
|---|
| 258 | <li><strong>C.</strong> State on the Title page the name of the publisher of the
|
|---|
| 259 | Modified Version, as the publisher.</li>
|
|---|
| 260 | <li><strong>D.</strong> Preserve all the copyright notices of the Document.</li>
|
|---|
| 261 | <li><strong>E.</strong> Add an appropriate copyright notice for your modifications
|
|---|
| 262 | adjacent to the other copyright notices.</li>
|
|---|
| 263 |
|
|---|
| 264 | <li><strong>F.</strong> Include, immediately after the copyright notices, a license notice
|
|---|
| 265 | giving the public permission to use the Modified Version under the
|
|---|
| 266 | terms of this License, in the form shown in the Addendum below.</li>
|
|---|
| 267 | <li><strong>G.</strong> Preserve in that license notice the full lists of Invariant Sections
|
|---|
| 268 | and required Cover Texts given in the Document's license notice.</li>
|
|---|
| 269 | <li><strong>H.</strong> Include an unaltered copy of this License.</li>
|
|---|
| 270 | <li><strong>I.</strong> Preserve the section Entitled "History", Preserve its Title, and add
|
|---|
| 271 | to it an item stating at least the title, year, new authors, and
|
|---|
| 272 | publisher of the Modified Version as given on the Title Page. If
|
|---|
| 273 | there is no section Entitled "History" in the Document, create one
|
|---|
| 274 | stating the title, year, authors, and publisher of the Document as
|
|---|
| 275 | given on its Title Page, then add an item describing the Modified
|
|---|
| 276 | Version as stated in the previous sentence.</li>
|
|---|
| 277 |
|
|---|
| 278 | <li><strong>J.</strong> Preserve the network location, if any, given in the Document for
|
|---|
| 279 | public access to a Transparent copy of the Document, and likewise
|
|---|
| 280 | the network locations given in the Document for previous versions
|
|---|
| 281 | it was based on. These may be placed in the "History" section.
|
|---|
| 282 | You may omit a network location for a work that was published at
|
|---|
| 283 | least four years before the Document itself, or if the original
|
|---|
| 284 | publisher of the version it refers to gives permission.</li>
|
|---|
| 285 | <li><strong>K.</strong> For any section Entitled "Acknowledgements" or "Dedications",
|
|---|
| 286 | Preserve the Title of the section, and preserve in the section all
|
|---|
| 287 | the substance and tone of each of the contributor acknowledgements
|
|---|
| 288 | and/or dedications given therein.</li>
|
|---|
| 289 | <li><strong>L.</strong> Preserve all the Invariant Sections of the Document,
|
|---|
| 290 | unaltered in their text and in their titles. Section numbers
|
|---|
| 291 | or the equivalent are not considered part of the section titles.</li>
|
|---|
| 292 | <li><strong>M.</strong> Delete any section Entitled "Endorsements". Such a section
|
|---|
| 293 | may not be included in the Modified Version.</li>
|
|---|
| 294 |
|
|---|
| 295 | <li><strong>N.</strong> Do not retitle any existing section to be Entitled "Endorsements"
|
|---|
| 296 | or to conflict in title with any Invariant Section.</li>
|
|---|
| 297 | <li><strong>O.</strong> Preserve any Warranty Disclaimers.</li>
|
|---|
| 298 | </ul>
|
|---|
| 299 |
|
|---|
| 300 | <p>
|
|---|
| 301 | If the Modified Version includes new front-matter sections or
|
|---|
| 302 | appendices that qualify as Secondary Sections and contain no material
|
|---|
| 303 | copied from the Document, you may at your option designate some or all
|
|---|
| 304 | of these sections as invariant. To do this, add their titles to the
|
|---|
| 305 | list of Invariant Sections in the Modified Version's license notice.
|
|---|
| 306 | These titles must be distinct from any other section titles.
|
|---|
| 307 |
|
|---|
| 308 | </p>
|
|---|
| 309 |
|
|---|
| 310 | <p>
|
|---|
| 311 | You may add a section Entitled "Endorsements", provided it contains
|
|---|
| 312 | nothing but endorsements of your Modified Version by various
|
|---|
| 313 | parties--for example, statements of peer review or that the text has
|
|---|
| 314 | been approved by an organization as the authoritative definition of a
|
|---|
| 315 | standard.
|
|---|
| 316 | </p>
|
|---|
| 317 |
|
|---|
| 318 | <p>
|
|---|
| 319 | You may add a passage of up to five words as a Front-Cover Text, and a
|
|---|
| 320 | passage of up to 25 words as a Back-Cover Text, to the end of the list
|
|---|
| 321 | of Cover Texts in the Modified Version. Only one passage of
|
|---|
| 322 | Front-Cover Text and one of Back-Cover Text may be added by (or
|
|---|
| 323 | through arrangements made by) any one entity. If the Document already
|
|---|
| 324 | includes a cover text for the same cover, previously added by you or
|
|---|
| 325 | by arrangement made by the same entity you are acting on behalf of,
|
|---|
| 326 | you may not add another; but you may replace the old one, on explicit
|
|---|
| 327 | permission from the previous publisher that added the old one.
|
|---|
| 328 | </p>
|
|---|
| 329 |
|
|---|
| 330 | <p>
|
|---|
| 331 | The author(s) and publisher(s) of the Document do not by this License
|
|---|
| 332 | give permission to use their names for publicity for or to assert or
|
|---|
| 333 | imply endorsement of any Modified Version.
|
|---|

| 337 | <strong>5. COMBINING DOCUMENTS</strong>
|
|---|
| 338 | </p>
|
|---|
| 339 |
|
|---|
| 340 | <p>
|
|---|
| 341 | You may combine the Document with other documents released under this
|
|---|
| 342 | License, under the terms defined in section 4 above for modified
|
|---|
| 343 | versions, provided that you include in the combination all of the

| 347 | </p>
|
|---|
| 348 |
|
|---|
| 349 | <p>
|

| 350 | The combined work need only contain one copy of this License, and
|
|---|
| 351 | multiple identical Invariant Sections may be replaced with a single
|
|---|
| 352 | copy. If there are multiple Invariant Sections with the same name but
|
|---|
| 353 | different contents, make the title of each such section unique by
|
|---|
| 354 | adding at the end of it, in parentheses, the name of the original
|
|---|
| 355 | author or publisher of that section if known, or else a unique number.
|

| 356 | Make the same adjustment to the section titles in the list of
|

| 357 | Invariant Sections in the license notice of the combined work.

|
|---|
| 361 | In the combination, you must combine any sections Entitled "History"
|
|---|
| 362 | in the various original documents, forming one section Entitled
|
|---|
| 363 | "History"; likewise combine any sections Entitled "Acknowledgements",
|
|---|
| 364 | and any sections Entitled "Dedications". You must delete all sections
|
|---|
| 365 | Entitled "Endorsements."

| 369 | <strong>6. COLLECTIONS OF DOCUMENTS</strong>
|
|---|
| 370 | </p>
|
|---|
| 371 |
|
|---|
| 372 | <p>
|
|---|
| 373 | You may make a collection consisting of the Document and other documents
|
|---|
| 374 | released under this License, and replace the individual copies of this
|
|---|
| 375 | License in the various documents with a single copy that is included in
|
|---|
| 376 | the collection, provided that you follow the rules of this License for
|
|---|
| 377 | verbatim copying of each of the documents in all other respects.
|
|---|
| 378 | </p>
|
|---|
| 379 |
|
|---|
| 380 | <p>
|
|---|
| 381 | You may extract a single document from such a collection, and distribute
|
|---|
| 382 | it individually under this License, provided you insert a copy of this
|
|---|
| 383 | License into the extracted document, and follow this License in all
|
|---|
| 384 | other respects regarding verbatim copying of that document.
|
|---|
| 385 | </p>
|
|---|
| 386 |
|
|---|
| 387 | <p>
|
|---|
| 388 | <strong>7. AGGREGATION WITH INDEPENDENT WORKS</strong>
|
|---|
| 389 | </p>
|
|---|
| 390 |
|
|---|
| 391 | <p>
|
|---|
| 392 | A compilation of the Document or its derivatives with other separate
|
|---|
| 393 | and independent documents or works, in or on a volume of a storage or
|
|---|
| 394 | distribution medium, is called an "aggregate" if the copyright
|
|---|
| 395 | resulting from the compilation is not used to limit the legal rights
|
|---|
| 396 | of the compilation's users beyond what the individual works permit.
|
|---|
| 397 | When the Document is included in an aggregate, this License does not
|
|---|
| 398 | apply to the other works in the aggregate which are not themselves
|
|---|
| 399 | derivative works of the Document.
|
|---|
| 400 | </p>
|
|---|
| 401 |
|
|---|
| 402 | <p>
|
|---|
| 403 |
|
|---|
| 404 | If the Cover Text requirement of section 3 is applicable to these
|
|---|
| 405 | copies of the Document, then if the Document is less than one half of
|
|---|
| 406 | the entire aggregate, the Document's Cover Texts may be placed on
|
|---|
| 407 | covers that bracket the Document within the aggregate, or the
|
|---|
| 408 | electronic equivalent of covers if the Document is in electronic form.
|
|---|
| 409 | Otherwise they must appear on printed covers that bracket the whole
|
|---|
| 410 | aggregate.
|
|---|
| 411 | </p>
|
|---|
| 412 |
|
|---|
| 413 | <p>
|
|---|
| 414 | <strong>8. TRANSLATION</strong>
|
|---|
| 415 | </p>
|
|---|
| 416 |
|
|---|
| 417 | <p>
|
|---|
| 418 | Translation is considered a kind of modification, so you may
|
|---|
| 419 | distribute translations of the Document under the terms of section 4.
|
|---|
| 420 | Replacing Invariant Sections with translations requires special
|
|---|
| 421 | permission from their copyright holders, but you may include
|
|---|
| 422 | translations of some or all Invariant Sections in addition to the
|
|---|
| 423 | original versions of these Invariant Sections. You may include a
|
|---|
| 424 | translation of this License, and all the license notices in the
|
|---|
| 425 | Document, and any Warranty Disclaimers, provided that you also include
|
|---|
| 426 | the original English version of this License and the original versions
|
|---|
| 427 | of those notices and disclaimers. In case of a disagreement between
|
|---|
| 428 | the translation and the original version of this License or a notice
|
|---|
| 429 | or disclaimer, the original version will prevail.
|
|---|
| 430 | </p>
|
|---|
| 431 |
|
|---|
| 432 | <p>
|
|---|
| 433 |
|
|---|
| 434 | If a section in the Document is Entitled "Acknowledgements",
|
|---|
| 435 | "Dedications", or "History", the requirement (section 4) to Preserve
|
|---|
| 436 | its Title (section 1) will typically require changing the actual
|
|---|
| 437 | title.

| 442 | </p>
|
|---|
| 443 |
|
|---|
| 444 | <p>
|
|---|
| 445 | You may not copy, modify, sublicense, or distribute the Document except
|
|---|
| 446 | as expressly provided for under this License. Any other attempt to
|
|---|
| 447 | copy, modify, sublicense or distribute the Document is void, and will
|
|---|
| 448 | automatically terminate your rights under this License. However,
|
|---|
| 449 | parties who have received copies, or rights, from you under this
|
|---|
| 450 | License will not have their licenses terminated so long as such
|
|---|
| 451 | parties remain in full compliance.

| 468 | Each version of the License is given a distinguishing version number.
|
|---|
| 469 | If the Document specifies that a particular numbered version of this
|
|---|
| 470 | License "or any later version" applies to it, you have the option of
|
|---|
| 471 | following the terms and conditions either of that specified version or
|
|---|
| 472 | of any later version that has been published (not as a draft) by the
|
|---|
| 473 | Free Software Foundation. If the Document does not specify a version
|
|---|
| 474 | number of this License, you may choose any version ever published (not
|
|---|
| 475 | as a draft) by the Free Software Foundation.
