1.1 ! root 1: @node Free Documentation License ! 2: @appendix GNU Free Documentation License ! 3: ! 4: @cindex FDL, GNU Free Documentation License ! 5: @center Version 1.1, March 2000 ! 6: ! 7: @display ! 8: Copyright @copyright{} 2000 Free Software Foundation, Inc. ! 9: 59 Temple Place, Suite 330, Boston, MA 02111-1307, USA ! 10: ! 11: Everyone is permitted to copy and distribute verbatim copies ! 12: of this license document, but changing it is not allowed. ! 13: @end display ! 14: ! 15: @enumerate 0 ! 16: @item ! 17: PREAMBLE ! 18: ! 19: The purpose of this License is to make a manual, textbook, or other ! 20: written document @dfn{free} in the sense of freedom: to assure everyone ! 21: the effective freedom to copy and redistribute it, with or without ! 22: modifying it, either commercially or noncommercially. Secondarily, ! 23: this License preserves for the author and publisher a way to get ! 24: credit for their work, while not being considered responsible for ! 25: modifications made by others. ! 26: ! 27: This License is a kind of ``copyleft'', which means that derivative ! 28: works of the document must themselves be free in the same sense. It ! 29: complements the GNU General Public License, which is a copyleft ! 30: license designed for free software. ! 31: ! 32: We have designed this License in order to use it for manuals for free ! 33: software, because free software needs free documentation: a free ! 34: program should come with manuals providing the same freedoms that the ! 35: software does. But this License is not limited to software manuals; ! 36: it can be used for any textual work, regardless of subject matter or ! 37: whether it is published as a printed book. We recommend this License ! 38: principally for works whose purpose is instruction or reference. ! 39: ! 40: @item ! 41: APPLICABILITY AND DEFINITIONS ! 42: ! 43: This License applies to any manual or other work that contains a ! 44: notice placed by the copyright holder saying it can be distributed ! 45: under the terms of this License. The ``Document'', below, refers to any ! 46: such manual or work. Any member of the public is a licensee, and is ! 47: addressed as ``you''. ! 48: ! 49: A ``Modified Version'' of the Document means any work containing the ! 50: Document or a portion of it, either copied verbatim, or with ! 51: modifications and/or translated into another language. ! 52: ! 53: A ``Secondary Section'' is a named appendix or a front-matter section of ! 54: the Document that deals exclusively with the relationship of the ! 55: publishers or authors of the Document to the Document's overall subject ! 56: (or to related matters) and contains nothing that could fall directly ! 57: within that overall subject. (For example, if the Document is in part a ! 58: textbook of mathematics, a Secondary Section may not explain any ! 59: mathematics.) The relationship could be a matter of historical ! 60: connection with the subject or with related matters, or of legal, ! 61: commercial, philosophical, ethical or political position regarding ! 62: them. ! 63: ! 64: The ``Invariant Sections'' are certain Secondary Sections whose titles ! 65: are designated, as being those of Invariant Sections, in the notice ! 66: that says that the Document is released under this License. ! 67: ! 68: The ``Cover Texts'' are certain short passages of text that are listed, ! 69: as Front-Cover Texts or Back-Cover Texts, in the notice that says that ! 70: the Document is released under this License. ! 71: ! 72: A ``Transparent'' copy of the Document means a machine-readable copy, ! 73: represented in a format whose specification is available to the ! 74: general public, whose contents can be viewed and edited directly and ! 75: straightforwardly with generic text editors or (for images composed of ! 76: pixels) generic paint programs or (for drawings) some widely available ! 77: drawing editor, and that is suitable for input to text formatters or ! 78: for automatic translation to a variety of formats suitable for input ! 79: to text formatters. A copy made in an otherwise Transparent file ! 80: format whose markup has been designed to thwart or discourage ! 81: subsequent modification by readers is not Transparent. A copy that is ! 82: not ``Transparent'' is called ``Opaque''. ! 83: ! 84: Examples of suitable formats for Transparent copies include plain ! 85: @sc{ascii} without markup, Texinfo input format, La@TeX{} input format, ! 86: @acronym{SGML} or @acronym{XML} using a publicly available ! 87: @acronym{DTD}, and standard-conforming simple @acronym{HTML} designed ! 88: for human modification. Opaque formats include PostScript, ! 89: @acronym{PDF}, proprietary formats that can be read and edited only by ! 90: proprietary word processors, @acronym{SGML} or @acronym{XML} for which ! 91: the @acronym{DTD} and/or processing tools are not generally available, ! 92: and the machine-generated @acronym{HTML} produced by some word ! 93: processors for output purposes only. ! 94: ! 95: The ``Title Page'' means, for a printed book, the title page itself, ! 96: plus such following pages as are needed to hold, legibly, the material ! 97: this License requires to appear in the title page. For works in ! 98: formats which do not have any title page as such, ``Title Page'' means ! 99: the text near the most prominent appearance of the work's title, ! 100: preceding the beginning of the body of the text. ! 101: ! 102: @item ! 103: VERBATIM COPYING ! 104: ! 105: You may copy and distribute the Document in any medium, either ! 106: commercially or noncommercially, provided that this License, the ! 107: copyright notices, and the license notice saying this License applies ! 108: to the Document are reproduced in all copies, and that you add no other ! 109: conditions whatsoever to those of this License. You may not use ! 110: technical measures to obstruct or control the reading or further ! 111: copying of the copies you make or distribute. However, you may accept ! 112: compensation in exchange for copies. If you distribute a large enough ! 113: number of copies you must also follow the conditions in section 3. ! 114: ! 115: You may also lend copies, under the same conditions stated above, and ! 116: you may publicly display copies. ! 117: ! 118: @item ! 119: COPYING IN QUANTITY ! 120: ! 121: If you publish printed copies of the Document numbering more than 100, ! 122: and the Document's license notice requires Cover Texts, you must enclose ! 123: the copies in covers that carry, clearly and legibly, all these Cover ! 124: Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on ! 125: the back cover. Both covers must also clearly and legibly identify ! 126: you as the publisher of these copies. The front cover must present ! 127: the full title with all words of the title equally prominent and ! 128: visible. You may add other material on the covers in addition. ! 129: Copying with changes limited to the covers, as long as they preserve ! 130: the title of the Document and satisfy these conditions, can be treated ! 131: as verbatim copying in other respects. ! 132: ! 133: If the required texts for either cover are too voluminous to fit ! 134: legibly, you should put the first ones listed (as many as fit ! 135: reasonably) on the actual cover, and continue the rest onto adjacent ! 136: pages. ! 137: ! 138: If you publish or distribute Opaque copies of the Document numbering ! 139: more than 100, you must either include a machine-readable Transparent ! 140: copy along with each Opaque copy, or state in or with each Opaque copy ! 141: a publicly-accessible computer-network location containing a complete ! 142: Transparent copy of the Document, free of added material, which the ! 143: general network-using public has access to download anonymously at no ! 144: charge using public-standard network protocols. If you use the latter ! 145: option, you must take reasonably prudent steps, when you begin ! 146: distribution of Opaque copies in quantity, to ensure that this ! 147: Transparent copy will remain thus accessible at the stated location ! 148: until at least one year after the last time you distribute an Opaque ! 149: copy (directly or through your agents or retailers) of that edition to ! 150: the public. ! 151: ! 152: It is requested, but not required, that you contact the authors of the ! 153: Document well before redistributing any large number of copies, to give ! 154: them a chance to provide you with an updated version of the Document. ! 155: ! 156: @item ! 157: MODIFICATIONS ! 158: ! 159: You may copy and distribute a Modified Version of the Document under ! 160: the conditions of sections 2 and 3 above, provided that you release ! 161: the Modified Version under precisely this License, with the Modified ! 162: Version filling the role of the Document, thus licensing distribution ! 163: and modification of the Modified Version to whoever possesses a copy ! 164: of it. In addition, you must do these things in the Modified Version: ! 165: ! 166: @enumerate A ! 167: @item ! 168: Use in the Title Page (and on the covers, if any) a title distinct ! 169: from that of the Document, and from those of previous versions ! 170: (which should, if there were any, be listed in the History section ! 171: of the Document). You may use the same title as a previous version ! 172: if the original publisher of that version gives permission. ! 173: ! 174: @item ! 175: List on the Title Page, as authors, one or more persons or entities ! 176: responsible for authorship of the modifications in the Modified ! 177: Version, together with at least five of the principal authors of the ! 178: Document (all of its principal authors, if it has less than five). ! 179: ! 180: @item ! 181: State on the Title page the name of the publisher of the ! 182: Modified Version, as the publisher. ! 183: ! 184: @item ! 185: Preserve all the copyright notices of the Document. ! 186: ! 187: @item ! 188: Add an appropriate copyright notice for your modifications ! 189: adjacent to the other copyright notices. ! 190: ! 191: @item ! 192: Include, immediately after the copyright notices, a license notice ! 193: giving the public permission to use the Modified Version under the ! 194: terms of this License, in the form shown in the Addendum below. ! 195: ! 196: @item ! 197: Preserve in that license notice the full lists of Invariant Sections ! 198: and required Cover Texts given in the Document's license notice. ! 199: ! 200: @item ! 201: Include an unaltered copy of this License. ! 202: ! 203: @item ! 204: Preserve the section entitled ``History'', and its title, and add to ! 205: it an item stating at least the title, year, new authors, and ! 206: publisher of the Modified Version as given on the Title Page. If ! 207: there is no section entitled ``History'' in the Document, create one ! 208: stating the title, year, authors, and publisher of the Document as ! 209: given on its Title Page, then add an item describing the Modified ! 210: Version as stated in the previous sentence. ! 211: ! 212: @item ! 213: Preserve the network location, if any, given in the Document for ! 214: public access to a Transparent copy of the Document, and likewise ! 215: the network locations given in the Document for previous versions ! 216: it was based on. These may be placed in the ``History'' section. ! 217: You may omit a network location for a work that was published at ! 218: least four years before the Document itself, or if the original ! 219: publisher of the version it refers to gives permission. ! 220: ! 221: @item ! 222: In any section entitled ``Acknowledgments'' or ``Dedications'', ! 223: preserve the section's title, and preserve in the section all the ! 224: substance and tone of each of the contributor acknowledgments ! 225: and/or dedications given therein. ! 226: ! 227: @item ! 228: Preserve all the Invariant Sections of the Document, ! 229: unaltered in their text and in their titles. Section numbers ! 230: or the equivalent are not considered part of the section titles. ! 231: ! 232: @item ! 233: Delete any section entitled ``Endorsements''. Such a section ! 234: may not be included in the Modified Version. ! 235: ! 236: @item ! 237: Do not retitle any existing section as ``Endorsements'' ! 238: or to conflict in title with any Invariant Section. ! 239: @end enumerate ! 240: ! 241: If the Modified Version includes new front-matter sections or ! 242: appendices that qualify as Secondary Sections and contain no material ! 243: copied from the Document, you may at your option designate some or all ! 244: of these sections as invariant. To do this, add their titles to the ! 245: list of Invariant Sections in the Modified Version's license notice. ! 246: These titles must be distinct from any other section titles. ! 247: ! 248: You may add a section entitled ``Endorsements'', provided it contains ! 249: nothing but endorsements of your Modified Version by various ! 250: parties---for example, statements of peer review or that the text has ! 251: been approved by an organization as the authoritative definition of a ! 252: standard. ! 253: ! 254: You may add a passage of up to five words as a Front-Cover Text, and a ! 255: passage of up to 25 words as a Back-Cover Text, to the end of the list ! 256: of Cover Texts in the Modified Version. Only one passage of ! 257: Front-Cover Text and one of Back-Cover Text may be added by (or ! 258: through arrangements made by) any one entity. If the Document already ! 259: includes a cover text for the same cover, previously added by you or ! 260: by arrangement made by the same entity you are acting on behalf of, ! 261: you may not add another; but you may replace the old one, on explicit ! 262: permission from the previous publisher that added the old one. ! 263: ! 264: The author(s) and publisher(s) of the Document do not by this License ! 265: give permission to use their names for publicity for or to assert or ! 266: imply endorsement of any Modified Version. ! 267: ! 268: @item ! 269: COMBINING DOCUMENTS ! 270: ! 271: You may combine the Document with other documents released under this ! 272: License, under the terms defined in section 4 above for modified ! 273: versions, provided that you include in the combination all of the ! 274: Invariant Sections of all of the original documents, unmodified, and ! 275: list them all as Invariant Sections of your combined work in its ! 276: license notice. ! 277: ! 278: The combined work need only contain one copy of this License, and ! 279: multiple identical Invariant Sections may be replaced with a single ! 280: copy. If there are multiple Invariant Sections with the same name but ! 281: different contents, make the title of each such section unique by ! 282: adding at the end of it, in parentheses, the name of the original ! 283: author or publisher of that section if known, or else a unique number. ! 284: Make the same adjustment to the section titles in the list of ! 285: Invariant Sections in the license notice of the combined work. ! 286: ! 287: In the combination, you must combine any sections entitled ``History'' ! 288: in the various original documents, forming one section entitled ! 289: ``History''; likewise combine any sections entitled ``Acknowledgments'', ! 290: and any sections entitled ``Dedications''. You must delete all sections ! 291: entitled ``Endorsements.'' ! 292: ! 293: @item ! 294: COLLECTIONS OF DOCUMENTS ! 295: ! 296: You may make a collection consisting of the Document and other documents ! 297: released under this License, and replace the individual copies of this ! 298: License in the various documents with a single copy that is included in ! 299: the collection, provided that you follow the rules of this License for ! 300: verbatim copying of each of the documents in all other respects. ! 301: ! 302: You may extract a single document from such a collection, and distribute ! 303: it individually under this License, provided you insert a copy of this ! 304: License into the extracted document, and follow this License in all ! 305: other respects regarding verbatim copying of that document. ! 306: ! 307: @item ! 308: AGGREGATION WITH INDEPENDENT WORKS ! 309: ! 310: A compilation of the Document or its derivatives with other separate ! 311: and independent documents or works, in or on a volume of a storage or ! 312: distribution medium, does not as a whole count as a Modified Version ! 313: of the Document, provided no compilation copyright is claimed for the ! 314: compilation. Such a compilation is called an ``aggregate'', and this ! 315: License does not apply to the other self-contained works thus compiled ! 316: with the Document, on account of their being thus compiled, if they ! 317: are not themselves derivative works of the Document. ! 318: ! 319: If the Cover Text requirement of section 3 is applicable to these ! 320: copies of the Document, then if the Document is less than one quarter ! 321: of the entire aggregate, the Document's Cover Texts may be placed on ! 322: covers that surround only the Document within the aggregate. ! 323: Otherwise they must appear on covers around the whole aggregate. ! 324: ! 325: @item ! 326: TRANSLATION ! 327: ! 328: Translation is considered a kind of modification, so you may ! 329: distribute translations of the Document under the terms of section 4. ! 330: Replacing Invariant Sections with translations requires special ! 331: permission from their copyright holders, but you may include ! 332: translations of some or all Invariant Sections in addition to the ! 333: original versions of these Invariant Sections. You may include a ! 334: translation of this License provided that you also include the ! 335: original English version of this License. In case of a disagreement ! 336: between the translation and the original English version of this ! 337: License, the original English version will prevail. ! 338: ! 339: @item ! 340: TERMINATION ! 341: ! 342: You may not copy, modify, sublicense, or distribute the Document except ! 343: as expressly provided for under this License. Any other attempt to ! 344: copy, modify, sublicense or distribute the Document is void, and will ! 345: automatically terminate your rights under this License. However, ! 346: parties who have received copies, or rights, from you under this ! 347: License will not have their licenses terminated so long as such ! 348: parties remain in full compliance. ! 349: ! 350: @item ! 351: FUTURE REVISIONS OF THIS LICENSE ! 352: ! 353: The Free Software Foundation may publish new, revised versions ! 354: of the GNU Free Documentation License from time to time. Such new ! 355: versions will be similar in spirit to the present version, but may ! 356: differ in detail to address new problems or concerns. See ! 357: @uref{http://www.gnu.org/copyleft/}. ! 358: ! 359: Each version of the License is given a distinguishing version number. ! 360: If the Document specifies that a particular numbered version of this ! 361: License ``or any later version'' applies to it, you have the option of ! 362: following the terms and conditions either of that specified version or ! 363: of any later version that has been published (not as a draft) by the ! 364: Free Software Foundation. If the Document does not specify a version ! 365: number of this License, you may choose any version ever published (not ! 366: as a draft) by the Free Software Foundation. ! 367: @end enumerate ! 368: ! 369: @page ! 370: @appendixsubsec ADDENDUM: How to use this License for your documents ! 371: ! 372: To use this License in a document you have written, include a copy of ! 373: the License in the document and put the following copyright and ! 374: license notices just after the title page: ! 375: ! 376: @smallexample ! 377: @group ! 378: Copyright (C) @var{year} @var{your name}. ! 379: Permission is granted to copy, distribute and/or modify this document ! 380: under the terms of the GNU Free Documentation License, Version 1.1 ! 381: or any later version published by the Free Software Foundation; ! 382: with the Invariant Sections being @var{list their titles}, with the ! 383: Front-Cover Texts being @var{list}, and with the Back-Cover Texts being @var{list}. ! 384: A copy of the license is included in the section entitled ``GNU ! 385: Free Documentation License''. ! 386: @end group ! 387: @end smallexample ! 388: ! 389: If you have no Invariant Sections, write ``with no Invariant Sections'' ! 390: instead of saying which ones are invariant.
