|---|
| 28 |  | 
|---|
| 29 | Copyright (C) 2000  Free Software Foundation, Inc.    59 Temple | 
|---|
| 30 | Place, Suite 330, Boston, MA  02111-1307  USA | 
|---|
| 31 |  | 
|---|
| 32 | Everyone is permitted to copy and distribute verbatim copies  of | 
|---|
| 33 | this license document, but changing it is not allowed. | 
|---|
| 34 |  | 
|---|
| 35 | 0. PREAMBLE | 
|---|
| 36 |  | 
|---|
| 37 | The purpose of this License is to make a manual, textbook, or other | 
|---|
| 38 | written document "free" in the sense of freedom: to assure everyone the | 
|---|
| 39 | effective freedom to copy and redistribute it, with or without | 
|---|
| 40 | modifying it, either commercially or noncommercially.  Secondarily, | 
|---|
| 41 | this License preserves for the author and publisher a way to get credit | 
|---|
| 42 | for their work, while not being considered responsible for | 
|---|
| 43 | modifications made by others. | 
|---|
| 44 |  | 
|---|
| 45 | This License is a kind of "copyleft", which means that derivative | 
|---|
| 46 | works of the document must themselves be free in the same sense.  It | 
|---|
| 47 | complements the GNU General Public License, which is a copyleft license | 
|---|
| 48 | designed for free software. | 
|---|
| 49 |  | 
|---|
| 50 | We have designed this License in order to use it for manuals for free | 
|---|
| 51 | software, because free software needs free documentation: a free | 
|---|
| 52 | program should come with manuals providing the same freedoms that the | 
|---|
| 53 | software does.  But this License is not limited to software manuals; it | 
|---|
| 54 | can be used for any textual work, regardless of subject matter or | 
|---|
| 55 | whether it is published as a printed book.  We recommend this License | 
|---|
| 56 | principally for works whose purpose is instruction or reference. | 
|---|
| 57 |  | 
|---|
| 58 | 1. APPLICABILITY AND DEFINITIONS | 
|---|
| 59 |  | 
|---|
| 60 | This License applies to any manual or other work that contains a | 
|---|
| 61 | notice placed by the copyright holder saying it can be distributed | 
|---|
| 62 | under the terms of this License.  The "Document", below, refers to any | 
|---|
| 63 | such manual or work.  Any member of the public is a licensee, and is | 
|---|
| 64 | addressed as "you". | 
|---|
| 65 |  | 
|---|
| 66 | A "Modified Version" of the Document means any work containing the | 
|---|
| 67 | Document or a portion of it, either copied verbatim, or with | 
|---|
| 68 | modifications and/or translated into another language. | 
|---|
| 69 |  | 
|---|
| 70 | A "Secondary Section" is a named appendix or a front-matter section | 
|---|
| 71 | of the Document that deals exclusively with the relationship of the | 
|---|
| 72 | publishers or authors of the Document to the Document's overall subject | 
|---|
| 73 | (or to related matters) and contains nothing that could fall directly | 
|---|
| 74 | within that overall subject.  (For example, if the Document is in part a | 
|---|
| 75 | textbook of mathematics, a Secondary Section may not explain any | 
|---|
| 76 | mathematics.)  The relationship could be a matter of historical | 
|---|
| 77 | connection with the subject or with related matters, or of legal, | 
|---|
| 78 | commercial, philosophical, ethical or political position regarding them. | 
|---|
| 79 |  | 
|---|
| 80 | The "Invariant Sections" are certain Secondary Sections whose titles | 
|---|
| 81 | are designated, as being those of Invariant Sections, in the notice | 
|---|
| 82 | that says that the Document is released under this License. | 
|---|
| 83 |  | 
|---|
| 84 | The "Cover Texts" are certain short passages of text that are listed, | 
|---|
| 85 | as Front-Cover Texts or Back-Cover Texts, in the notice that says that | 
|---|
| 86 | the Document is released under this License. | 
|---|
| 87 |  | 
|---|
| 88 | A "Transparent" copy of the Document means a machine-readable copy, | 
|---|
| 89 | represented in a format whose specification is available to the general | 
|---|
| 90 | public, whose contents can be viewed and edited directly and | 
|---|
| 91 | straightforwardly with generic text editors or (for images composed of | 
|---|
| 92 | pixels) generic paint programs or (for drawings) some widely available | 
|---|
| 93 | drawing editor, and that is suitable for input to text formatters or | 
|---|
| 94 | for automatic translation to a variety of formats suitable for input to | 
|---|
| 95 | text formatters.  A copy made in an otherwise Transparent file format | 
|---|
| 96 | whose markup has been designed to thwart or discourage subsequent | 
|---|
| 97 | modification by readers is not Transparent.  A copy that is not | 
|---|
| 98 | "Transparent" is called "Opaque". | 
|---|
| 99 |  | 
|---|
| 100 | Examples of suitable formats for Transparent copies include plain | 
|---|
| 101 | ASCII without markup, Texinfo input format, LaTeX input format, SGML or | 
|---|
| 102 | XML using a publicly available DTD, and standard-conforming simple HTML | 
|---|
| 103 | designed for human modification.  Opaque formats include PostScript, | 
|---|
| 104 | PDF, proprietary formats that can be read and edited only by | 
|---|
| 105 | proprietary word processors, SGML or XML for which the DTD and/or | 
|---|
| 106 | processing tools are not generally available, and the machine-generated | 
|---|
| 107 | HTML produced by some word processors for output purposes only. | 
|---|
| 108 |  | 
|---|
| 109 | The "Title Page" means, for a printed book, the title page itself, | 
|---|
| 110 | plus such following pages as are needed to hold, legibly, the material | 
|---|
| 111 | this License requires to appear in the title page.  For works in | 
|---|
| 112 | formats which do not have any title page as such, "Title Page" means | 
|---|
| 113 | the text near the most prominent appearance of the work's title, | 
|---|
| 114 | preceding the beginning of the body of the text. | 
|---|
| 115 |  | 
|---|
| 116 | 2. VERBATIM COPYING | 
|---|
| 117 |  | 
|---|
| 118 | You may copy and distribute the Document in any medium, either | 
|---|
| 119 | commercially or noncommercially, provided that this License, the | 
|---|
| 120 | copyright notices, and the license notice saying this License applies | 
|---|
| 121 | to the Document are reproduced in all copies, and that you add no other | 
|---|
| 122 | conditions whatsoever to those of this License.  You may not use | 
|---|
| 123 | technical measures to obstruct or control the reading or further | 
|---|
| 124 | copying of the copies you make or distribute.  However, you may accept | 
|---|
| 125 | compensation in exchange for copies.  If you distribute a large enough | 
|---|
| 126 | number of copies you must also follow the conditions in section 3. | 
|---|
| 127 |  | 
|---|
| 128 | You may also lend copies, under the same conditions stated above, and | 
|---|
| 129 | you may publicly display copies. | 
|---|
| 130 |  | 
|---|
| 131 | 3. COPYING IN QUANTITY | 
|---|
| 132 |  | 
|---|
| 133 | If you publish printed copies of the Document numbering more than | 
|---|
| 134 | 100, and the Document's license notice requires Cover Texts, you must | 
|---|
| 135 | enclose the copies in covers that carry, clearly and legibly, all these | 
|---|
| 136 | Cover Texts: Front-Cover Texts on the front cover, and Back-Cover Texts | 
|---|
| 137 | on the back cover.  Both covers must also clearly and legibly identify | 
|---|
| 138 | you as the publisher of these copies.  The front cover must present the | 
|---|
| 139 | full title with all words of the title equally prominent and visible. | 
|---|
| 140 | You may add other material on the covers in addition.  Copying with | 
|---|
| 141 | changes limited to the covers, as long as they preserve the title of | 
|---|
| 142 | the Document and satisfy these conditions, can be treated as verbatim | 
|---|
| 143 | copying in other respects. | 
|---|
| 144 |  | 
|---|
| 145 | If the required texts for either cover are too voluminous to fit | 
|---|
| 146 | legibly, you should put the first ones listed (as many as fit | 
|---|
| 147 | reasonably) on the actual cover, and continue the rest onto adjacent | 
|---|
| 148 | pages. | 
|---|
| 149 |  | 
|---|
| 150 | If you publish or distribute Opaque copies of the Document numbering | 
|---|
| 151 | more than 100, you must either include a machine-readable Transparent | 
|---|
| 152 | copy along with each Opaque copy, or state in or with each Opaque copy | 
|---|
| 153 | a publicly-accessible computer-network location containing a complete | 
|---|
| 154 | Transparent copy of the Document, free of added material, which the | 
|---|
| 155 | general network-using public has access to download anonymously at no | 
|---|
| 156 | charge using public-standard network protocols.  If you use the latter | 
|---|
| 157 | option, you must take reasonably prudent steps, when you begin | 
|---|
| 158 | distribution of Opaque copies in quantity, to ensure that this | 
|---|
| 159 | Transparent copy will remain thus accessible at the stated location | 
|---|
| 160 | until at least one year after the last time you distribute an Opaque | 
|---|
| 161 | copy (directly or through your agents or retailers) of that edition to | 
|---|
| 162 | the public. | 
|---|
| 163 |  | 
|---|
| 164 | It is requested, but not required, that you contact the authors of | 
|---|
| 165 | the Document well before redistributing any large number of copies, to | 
|---|
| 166 | give them a chance to provide you with an updated version of the | 
|---|
| 167 | Document. | 
|---|
| 168 |  | 
|---|
| 169 | 4. MODIFICATIONS | 
|---|
| 170 |  | 
|---|
| 171 | You may copy and distribute a Modified Version of the Document under | 
|---|
| 172 | the conditions of sections 2 and 3 above, provided that you release the | 
|---|
| 173 | Modified Version under precisely this License, with the Modified | 
|---|
| 174 | Version filling the role of the Document, thus licensing distribution | 
|---|
| 175 | and modification of the Modified Version to whoever possesses a copy of | 
|---|
| 176 | it.  In addition, you must do these things in the Modified Version: | 
|---|
| 177 |  | 
|---|
| 178 | A. Use in the Title Page (and on the covers, if any) a title distinct | 
|---|
| 179 | from that of the Document, and from those of previous versions | 
|---|
| 180 | (which should, if there were any, be listed in the History section | 
|---|
| 181 | of the Document).  You may use the same title as a previous version | 
|---|
| 182 | if the original publisher of that version gives permission.  B. List on | 
|---|
| 183 | the Title Page, as authors, one or more persons or entities | 
|---|
| 184 | responsible for authorship of the modifications in the Modified | 
|---|
| 185 | Version, together with at least five of the principal authors of the | 
|---|
| 186 | Document (all of its principal authors, if it has less than five).  C. | 
|---|
| 187 | State on the Title page the name of the publisher of the    Modified | 
|---|
| 188 | Version, as the publisher.  D. Preserve all the copyright notices of | 
|---|
| 189 | the Document.  E. Add an appropriate copyright notice for your | 
|---|
| 190 | modifications    adjacent to the other copyright notices.  F. Include, | 
|---|
| 191 | immediately after the copyright notices, a license notice    giving the | 
|---|
| 192 | public permission to use the Modified Version under the    terms of | 
|---|
| 193 | this License, in the form shown in the Addendum below.  G. Preserve in | 
|---|
| 194 | that license notice the full lists of Invariant Sections    and | 
|---|
| 195 | required Cover Texts given in the Document's license notice.  H. | 
|---|
| 196 | Include an unaltered copy of this License.  I. Preserve the section | 
|---|
| 197 | entitled "History", and its title, and add to    it an item stating at | 
|---|
| 198 | least the title, year, new authors, and    publisher of the Modified | 
|---|
| 199 | Version as given on the Title Page.  If    there is no section entitled | 
|---|
| 200 | "History" in the Document, create one    stating the title, year, | 
|---|
| 201 | authors, and publisher of the Document as    given on its Title Page, | 
|---|
| 202 | then add an item describing the Modified    Version as stated in the | 
|---|
| 203 | previous sentence.  J. Preserve the network location, if any, given in | 
|---|
| 204 | the Document for    public access to a Transparent copy of the | 
|---|
| 205 | Document, and likewise    the network locations given in the Document | 
|---|
| 206 | for previous versions    it was based on.  These may be placed in the | 
|---|
| 207 | "History" section.     You may omit a network location for a work that | 
|---|
| 208 | was published at    least four years before the Document itself, or if | 
|---|
| 209 | the original    publisher of the version it refers to gives permission. | 
|---|
| 210 | K. In any section entitled "Acknowledgements" or "Dedications", | 
|---|
| 211 | preserve the section's title, and preserve in the section all the | 
|---|
| 212 | substance and tone of each of the contributor acknowledgements | 
|---|
| 213 | and/or dedications given therein.  L. Preserve all the Invariant | 
|---|
| 214 | Sections of the Document,    unaltered in their text and in their | 
|---|
| 215 | titles.  Section numbers    or the equivalent are not considered part | 
|---|
| 216 | of the section titles.  M. Delete any section entitled "Endorsements". | 
|---|
| 217 | Such a section    may not be included in the Modified Version.  N. Do | 
|---|
| 218 | not retitle any existing section as "Endorsements"    or to conflict in | 
|---|
| 219 | title with any Invariant Section. | 
|---|
| 220 |  | 
|---|
| 221 | If the Modified Version includes new front-matter sections or | 
|---|
| 222 | appendices that qualify as Secondary Sections and contain no material | 
|---|
| 223 | copied from the Document, you may at your option designate some or all | 
|---|
| 224 | of these sections as invariant.  To do this, add their titles to the | 
|---|
| 225 | list of Invariant Sections in the Modified Version's license notice. | 
|---|
| 226 | These titles must be distinct from any other section titles. | 
|---|
| 227 |  | 
|---|
| 228 | You may add a section entitled "Endorsements", provided it contains | 
|---|
| 229 | nothing but endorsements of your Modified Version by various | 
|---|
| 230 | parties-for example, statements of peer review or that the text has | 
|---|
| 231 | been approved by an organization as the authoritative definition of a | 
|---|
| 232 | standard. | 
|---|
| 233 |  | 
|---|
| 234 | You may add a passage of up to five words as a Front-Cover Text, and | 
|---|
| 235 | a passage of up to 25 words as a Back-Cover Text, to the end of the list | 
|---|
| 236 | of Cover Texts in the Modified Version.  Only one passage of | 
|---|
| 237 | Front-Cover Text and one of Back-Cover Text may be added by (or through | 
|---|
| 238 | arrangements made by) any one entity.  If the Document already includes | 
|---|
| 239 | a cover text for the same cover, previously added by you or by | 
|---|
| 240 | arrangement made by the same entity you are acting on behalf of, you | 
|---|
| 241 | may not add another; but you may replace the old one, on explicit | 
|---|
| 242 | permission from the previous publisher that added the old one. | 
|---|
| 243 |  | 
|---|
| 244 | The author(s) and publisher(s) of the Document do not by this License | 
|---|
| 245 | give permission to use their names for publicity for or to assert or | 
|---|
| 246 | imply endorsement of any Modified Version. | 
|---|
| 247 |  | 
|---|
| 248 | 5. COMBINING DOCUMENTS | 
|---|
| 249 |  | 
|---|
| 250 | You may combine the Document with other documents released under this | 
|---|
| 251 | License, under the terms defined in section 4 above for modified | 
|---|
| 252 | versions, provided that you include in the combination all of the | 
|---|
| 253 | Invariant Sections of all of the original documents, unmodified, and | 
|---|
| 254 | list them all as Invariant Sections of your combined work in its | 
|---|
| 255 | license notice. | 
|---|
| 256 |  | 
|---|
| 257 | The combined work need only contain one copy of this License, and | 
|---|
| 258 | multiple identical Invariant Sections may be replaced with a single | 
|---|
| 259 | copy.  If there are multiple Invariant Sections with the same name but | 
|---|
| 260 | different contents, make the title of each such section unique by | 
|---|
| 261 | adding at the end of it, in parentheses, the name of the original | 
|---|
| 262 | author or publisher of that section if known, or else a unique number. | 
|---|
| 263 | Make the same adjustment to the section titles in the list of Invariant | 
|---|
| 264 | Sections in the license notice of the combined work. | 
|---|
| 265 |  | 
|---|
| 266 | In the combination, you must combine any sections entitled "History" | 
|---|
| 267 | in the various original documents, forming one section entitled | 
|---|
| 268 | "History"; likewise combine any sections entitled "Acknowledgements", | 
|---|
| 269 | and any sections entitled "Dedications".  You must delete all sections | 
|---|
| 270 | entitled "Endorsements." | 
|---|
| 271 |  | 
|---|
| 272 | 6. COLLECTIONS OF DOCUMENTS | 
|---|
| 273 |  | 
|---|
| 274 | You may make a collection consisting of the Document and other | 
|---|
| 275 | documents released under this License, and replace the individual | 
|---|
| 276 | copies of this License in the various documents with a single copy that | 
|---|
| 277 | is included in the collection, provided that you follow the rules of | 
|---|
| 278 | this License for verbatim copying of each of the documents in all other | 
|---|
| 279 | respects. | 
|---|
| 280 |  | 
|---|
| 281 | You may extract a single document from such a collection, and | 
|---|
| 282 | distribute it individually under this License, provided you insert a | 
|---|
| 283 | copy of this License into the extracted document, and follow this | 
|---|
| 284 | License in all other respects regarding verbatim copying of that | 
|---|
| 285 | document. | 
|---|
| 286 |  | 
|---|
| 287 | 7. AGGREGATION WITH INDEPENDENT WORKS | 
|---|
| 288 |  | 
|---|
| 289 | A compilation of the Document or its derivatives with other separate | 
|---|
| 290 | and independent documents or works, in or on a volume of a storage or | 
|---|
| 291 | distribution medium, does not as a whole count as a Modified Version of | 
|---|
| 292 | the Document, provided no compilation copyright is claimed for the | 
|---|
| 293 | compilation.  Such a compilation is called an "aggregate", and this | 
|---|
| 294 | License does not apply to the other self-contained works thus compiled | 
|---|
| 295 | with the Document, on account of their being thus compiled, if they are | 
|---|
| 296 | not themselves derivative works of the Document. | 
|---|
| 297 |  | 
|---|
| 298 | If the Cover Text requirement of section 3 is applicable to these | 
|---|
| 299 | copies of the Document, then if the Document is less than one quarter | 
|---|
| 300 | of the entire aggregate, the Document's Cover Texts may be placed on | 
|---|
| 301 | covers that surround only the Document within the aggregate.  Otherwise | 
|---|
| 302 | they must appear on covers around the whole aggregate. | 
|---|
| 303 |  | 
|---|
| 304 | 8. TRANSLATION | 
|---|
| 305 |  | 
|---|
| 306 | Translation is considered a kind of modification, so you may | 
|---|
| 307 | distribute translations of the Document under the terms of section 4. | 
|---|
| 308 | Replacing Invariant Sections with translations requires special | 
|---|
| 309 | permission from their copyright holders, but you may include | 
|---|
| 310 | translations of some or all Invariant Sections in addition to the | 
|---|
| 311 | original versions of these Invariant Sections.  You may include a | 
|---|
| 312 | translation of this License provided that you also include the original | 
|---|
| 313 | English version of this License.  In case of a disagreement between the | 
|---|
| 314 | translation and the original English version of this License, the | 
|---|
| 315 | original English version will prevail. | 
|---|
| 316 |  | 
|---|
| 317 | 9. TERMINATION | 
|---|
| 318 |  | 
|---|
| 319 | You may not copy, modify, sublicense, or distribute the Document | 
|---|
| 320 | except as expressly provided for under this License.  Any other attempt | 
|---|
| 321 | to copy, modify, sublicense or distribute the Document is void, and will | 
|---|
| 322 | automatically terminate your rights under this License.  However, | 
|---|
| 323 | parties who have received copies, or rights, from you under this | 
|---|
| 324 | License will not have their licenses terminated so long as such parties | 
|---|
| 325 | remain in full compliance. | 
|---|
| 326 |  | 
|---|
| 327 | 10. FUTURE REVISIONS OF THIS LICENSE | 
|---|
| 328 |  | 
|---|
| 329 | The Free Software Foundation may publish new, revised versions of | 
|---|
| 330 | the GNU Free Documentation License from time to time.  Such new | 
|---|
| 331 | versions will be similar in spirit to the present version, but may | 
|---|
| 332 | differ in detail to address new problems or concerns.  See | 
|---|
| 333 | http://www.gnu.org/copyleft/. | 
|---|
| 334 |  | 
|---|
