PREAMBLE | + | + The purpose of this License is to make a manual, textbook, or other | + functional and useful document "free" in the sense of freedom: to | + assure everyone the effective freedom to copy and redistribute it, | + with or without modifying it, either commercially or | + noncommercially. Secondarily, this License preserves for the | + author and publisher a way to get credit for their work, while not | + being considered responsible for modifications made by others. | + | + This License is a kind of "copyleft", which means that derivative | + works of the document must themselves be free in the same sense. | + It complements the GNU General Public License, which is a copyleft | + license designed for free software. | + | + We have designed this License in order to use it for manuals for | + free software, because free software needs free documentation: a | + free program should come with manuals providing the same freedoms | + that the software does. But this License is not limited to | + software manuals; it can be used for any textual work, regardless | + of subject matter or whether it is published as a printed book. | + We recommend this License principally for works whose purpose is | + instruction or reference. | + | + 1. APPLICABILITY AND DEFINITIONS | + | + This License applies to any manual or other work, in any medium, | + that contains a notice placed by the copyright holder saying it | + can be distributed under the terms of this License. Such a notice | + grants a world-wide, royalty-free license, unlimited in duration, | + to use that work under the conditions stated herein. The | + "Document", below, refers to any such manual or work. Any member | + of the public is a licensee, and is addressed as "you". You | + accept the license if you copy, modify or distribute the work in a | + way requiring permission under copyright law. | + | + A "Modified Version" of the Document means any work containing the | + Document or a portion of it, either copied verbatim, or with | + modifications and/or translated into another language. | + | + A "Secondary Section" is a named appendix or a front-matter section | + of the Document that deals exclusively with the relationship of the | + publishers or authors of the Document to the Document's overall | + subject (or to related matters) and contains nothing that could | + fall directly within that overall subject. (Thus, if the Document | + is in part a textbook of mathematics, a Secondary Section may not | + explain any mathematics.) The relationship could be a matter of | + historical connection with the subject or with related matters, or | + of legal, commercial, philosophical, ethical or political position | + regarding them. | + | + The "Invariant Sections" are certain Secondary Sections whose | + titles are designated, as being those of Invariant Sections, in | + the notice that says that the Document is released under this | + License. If a section does not fit the above definition of | + Secondary then it is not allowed to be designated as Invariant. | + The Document may contain zero Invariant Sections. If the Document | + does not identify any Invariant Sections then there are none. | + | + The "Cover Texts" are certain short passages of text that are | + listed, as Front-Cover Texts or Back-Cover Texts, in the notice | + that says that the Document is released under this License. A | + Front-Cover Text may be at most 5 words, and a Back-Cover Text may | + be at most 25 words. | + | + A "Transparent" copy of the Document means a machine-readable copy, | + represented in a format whose specification is available to the | + general public, that is suitable for revising the document | + straightforwardly with generic text editors or (for images | + composed of pixels) generic paint programs or (for drawings) some | + widely available drawing editor, and that is suitable for input to | + text formatters or for automatic translation to a variety of | + formats suitable for input to text formatters. A copy made in an | + otherwise Transparent file format whose markup, or absence of | + markup, has been arranged to thwart or discourage subsequent | + modification by readers is not Transparent. An image format is | + not Transparent if used for any substantial amount of text. A | + copy that is not "Transparent" is called "Opaque". | + | + Examples of suitable formats for Transparent copies include plain | + ASCII without markup, Texinfo input format, LaTeX input format, | + SGML or XML using a publicly available DTD, and | + standard-conforming simple HTML, PostScript or PDF designed for | + human modification. Examples of transparent image formats include | + PNG, XCF and JPG. Opaque formats include proprietary formats that | + can be read and edited only by proprietary word processors, SGML or | + XML for which the DTD and/or processing tools are not generally | + available, and the machine-generated HTML, PostScript or PDF | + produced by some word processors for output purposes only. | + | + The "Title Page" means, for a printed book, the title page itself, | + plus such following pages as are needed to hold, legibly, the | + material this License requires to appear in the title page. For | + works in formats which do not have any title page as such, "Title | + Page" means the text near the most prominent appearance of the | + work's title, preceding the beginning of the body of the text. | + | + A section "Entitled XYZ" means a named subunit of the Document | + whose title either is precisely XYZ or contains XYZ in parentheses | + following text that translates XYZ in another language. (Here XYZ | + stands for a specific section name mentioned below, such as | + "Acknowledgements", "Dedications", "Endorsements", or "History".) | + To "Preserve the Title" of such a section when you modify the | + Document means that it remains a section "Entitled XYZ" according | + to this definition. | + | + The Document may include Warranty Disclaimers next to the notice | + which states that this License applies to the Document. These | + Warranty Disclaimers are considered to be included by reference in | + this License, but only as regards disclaiming warranties: any other | + implication that these Warranty Disclaimers may have is void and | + has no effect on the meaning of this License. | + | + 2. VERBATIM COPYING | + | + You may copy and distribute the Document in any medium, either | + commercially or noncommercially, provided that this License, the | + copyright notices, and the license notice saying this License | + applies to the Document are reproduced in all copies, and that you | + add no other conditions whatsoever to those of this License. You | + may not use technical measures to obstruct or control the reading | + or further copying of the copies you make or distribute. However, | + you may accept compensation in exchange for copies. If you | + distribute a large enough number of copies you must also follow | + the conditions in section 3. | + | + You may also lend copies, under the same conditions stated above, | + and you may publicly display copies. | + | + 3. COPYING IN QUANTITY | + | + If you publish printed copies (or copies in media that commonly | + have printed covers) of the Document, numbering more than 100, and | + the Document's license notice requires Cover Texts, you must | + enclose the copies in covers that carry, clearly and legibly, all | + these Cover Texts: Front-Cover Texts on the front cover, and | + Back-Cover Texts on the back cover. Both covers must also clearly | + and legibly identify you as the publisher of these copies. The | + front cover must present the full title with all words of the | + title equally prominent and visible. You may add other material | + on the covers in addition. Copying with changes limited to the | + covers, as long as they preserve the title of the Document and | + satisfy these conditions, can be treated as verbatim copying in | + other respects. | + | + If the required texts for either cover are too voluminous to fit | + legibly, you should put the first ones listed (as many as fit | + reasonably) on the actual cover, and continue the rest onto | + adjacent pages. | + | + If you publish or distribute Opaque copies of the Document | + numbering more than 100, you must either include a | + machine-readable Transparent copy along with each Opaque copy, or | + state in or with each Opaque copy a computer-network location from | + which the general network-using public has access to download | + using public-standard network protocols a complete Transparent | + copy of the Document, free of added material. If you use the | + latter option, you must take reasonably prudent steps, when you | + begin distribution of Opaque copies in quantity, to ensure that | + this Transparent copy will remain thus accessible at the stated | + location until at least one year after the last time you | + distribute an Opaque copy (directly or through your agents or | + retailers) of that edition to the public. | + | + It is requested, but not required, that you contact the authors of | + the Document well before redistributing any large number of | + copies, to give them a chance to provide you with an updated | + version of the Document. | + | + 4. MODIFICATIONS | + | + You may copy and distribute a Modified Version of the Document | + under the conditions of sections 2 and 3 above, provided that you | + release the Modified Version under precisely this License, with | + the Modified Version filling the role of the Document, thus | + licensing distribution and modification of the Modified Version to | + whoever possesses a copy of it. In addition, you must do these | + things in the Modified Version: | + | + A. Use in the Title Page (and on the covers, if any) a title | + distinct from that of the Document, and from those of | + previous versions (which should, if there were any, be listed | + in the History section of the Document). You may use the | + same title as a previous version if the original publisher of | + that version gives permission. | + | + B. List on the Title Page, as authors, one or more persons or | + entities responsible for authorship of the modifications in | + the Modified Version, together with at least five of the | + principal authors of the Document (all of its principal | + authors, if it has fewer than five), unless they release you | + from this requirement. | + | + C. State on the Title page the name of the publisher of the | + Modified Version, as the publisher. | + | + D. Preserve all the copyright notices of the Document. | + | + E. Add an appropriate copyright notice for your modifications | + adjacent to the other copyright notices. | + | + F. Include, immediately after the copyright notices, a license | + notice giving the public permission to use the Modified | + Version under the terms of this License, in the form shown in | + the Addendum below. | + | + G. Preserve in that license notice the full lists of Invariant | + Sections and required Cover Texts given in the Document's | + license notice. | + | + H. Include an unaltered copy of this License. | + | + I. Preserve the section Entitled "History", Preserve its Title, | + and add to it an item stating at least the title, year, new | + authors, and publisher of the Modified Version as given on | + the Title Page. If there is no section Entitled "History" in | + the Document, create one stating the title, year, authors, | + and publisher of the Document as given on its Title Page, | + then add an item describing the Modified Version as stated in | + the previous sentence. | + | + J. Preserve the network location, if any, given in the Document | + for public access to a Transparent copy of the Document, and | + likewise the network locations given in the Document for | + previous versions it was based on. These may be placed in | + the "History" section. You may omit a network location for a | + work that was published at least four years before the | + Document itself, or if the original publisher of the version | + it refers to gives permission. | + | + K. For any section Entitled "Acknowledgements" or "Dedications", | + Preserve the Title of the section, and preserve in the | + section all the substance and tone of each of the contributor | + acknowledgements and/or dedications given therein. | + | + L. Preserve all the Invariant Sections of the Document, | + unaltered in their text and in their titles. Section numbers | + or the equivalent are not considered part of the section | + titles. | + | + M. Delete any section Entitled "Endorsements". Such a section | + may not be included in the Modified Version. | + | + N. Do not retitle any existing section to be Entitled | + "Endorsements" or to conflict in title with any Invariant | + Section. | + | + O. Preserve any Warranty Disclaimers. | + | + If the Modified Version includes new front-matter sections or | + appendices that qualify as Secondary Sections and contain no | + material copied from the Document, you may at your option | + designate some or all of these sections as invariant. To do this, | + add their titles to the list of Invariant Sections in the Modified | + Version's license notice. These titles must be distinct from any | + other section titles. | + | + You may add a section Entitled "Endorsements", provided it contains | + nothing but endorsements of your Modified Version by various | + parties--for example, statements of peer review or that the text | + has been approved by an organization as the authoritative | + definition of a standard. | + | + You may add a passage of up to five words as a Front-Cover Text, | + and a passage of up to 25 words as a Back-Cover Text, to the end | + of the list of Cover Texts in the Modified Version. Only one | + passage of Front-Cover Text and one of Back-Cover Text may be | + added by (or through arrangements made by) any one entity. If the | + Document already includes a cover text for the same cover, | + previously added by you or by arrangement made by the same entity | + you are acting on behalf of, you may not add another; but you may | + replace the old one, on explicit permission from the previous | + publisher that added the old one. | + | + The author(s) and publisher(s) of the Document do not by this | + License give permission to use their names for publicity for or to | + assert or imply endorsement of any Modified Version. | + | + 5. COMBINING DOCUMENTS | + | + You may combine the Document with other documents released under | + this License, under the terms defined in section 4 above for | + modified versions, provided that you include in the combination | + all of the Invariant Sections of all of the original documents, | + unmodified, and list them all as Invariant Sections of your | + combined work in its license notice, and that you preserve all | + their Warranty Disclaimers. | + | + The combined work need only contain one copy of this License, and | + multiple identical Invariant Sections may be replaced with a single | + copy. If there are multiple Invariant Sections with the same name | + but different contents, make the title of each such section unique | + by adding at the end of it, in parentheses, the name of the | + original author or publisher of that section if known, or else a | + unique number. Make the same adjustment to the section titles in | + the list of Invariant Sections in the license notice of the | + combined work. | + | + In the combination, you must combine any sections Entitled | + "History" in the various original documents, forming one section | + Entitled "History"; likewise combine any sections Entitled | + "Acknowledgements", and any sections Entitled "Dedications". You | + must delete all sections Entitled "Endorsements." | + | + 6. COLLECTIONS OF DOCUMENTS | + | + You may make a collection consisting of the Document and other | + documents released under this License, and replace the individual | + copies of this License in the various documents with a single copy | + that is included in the collection, provided that you follow the | + rules of this License for verbatim copying of each of the | + documents in all other respects. | + | + You may extract a single document from such a collection, and | + distribute it individually under this License, provided you insert | + a copy of this License into the extracted document, and follow | + this License in all other respects regarding verbatim copying of | + that document. | + | + 7. AGGREGATION WITH INDEPENDENT WORKS | + | + A compilation of the Document or its derivatives with other | + separate and independent documents or works, in or on a volume of | + a storage or distribution medium, is called an "aggregate" if the | + copyright resulting from the compilation is not used to limit the | + legal rights of the compilation's users beyond what the individual | + works permit. When the Document is included in an aggregate, this | + License does not apply to the other works in the aggregate which | + are not themselves derivative works of the Document. | + | + If the Cover Text requirement of section 3 is applicable to these | + copies of the Document, then if the Document is less than one half | + of the entire aggregate, the Document's Cover Texts may be placed | + on covers that bracket the Document within the aggregate, or the | + electronic equivalent of covers if the Document is in electronic | + form. Otherwise they must appear on printed covers that bracket | + the whole aggregate. | + | + 8. TRANSLATION | + | + Translation is considered a kind of modification, so you may | + distribute translations of the Document under the terms of section | + 4. Replacing Invariant Sections with translations requires special | + permission from their copyright holders, but you may include | + translations of some or all Invariant Sections in addition to the | + original versions of these Invariant Sections. You may include a | + translation of this License, and all the license notices in the | + Document, and any Warranty Disclaimers, provided that you also | + include the original English version of this License and the | + original versions of those notices and disclaimers. In case of a | + disagreement between the translation and the original version of | + this License or a notice or disclaimer, the original version will | + prevail. | + | + If a section in the Document is Entitled "Acknowledgements", | + "Dedications", or "History", the requirement (section 4) to | + Preserve its Title (section 1) will typically require changing the | + actual title. | + | + 9. TERMINATION | + | + You may not copy, modify, sublicense, or distribute the Document | + except as expressly provided for under this License. Any other | + attempt to copy, modify, sublicense or distribute the Document is | + void, and will automatically terminate your rights under this | + License. However, parties who have received copies, or rights, | + from you under this License will not have their licenses | + terminated so long as such parties remain in full compliance. | + | + 10. FUTURE REVISIONS OF THIS LICENSE | + | + The Free Software Foundation may publish new, revised versions of | + the GNU Free Documentation License from time to time. Such new | + versions will be similar in spirit to the present version, but may | + differ in detail to address new problems or concerns. See | + `http://www.gnu.org/copyleft/'. | + | + Each version of the License is given a distinguishing version | + number. If the Document specifies that a particular numbered | + version of this License "or any later version" applies to it, you | + have the option of following the terms and conditions either of | + that specified version or of any later version that has been | + published (not as a draft) by the Free Software Foundation. If | + the Document does not specify a version number of this License, | + you may choose any version ever published (not as a draft) by the | + Free Software Foundation. | + | + +File: slib.info, Node: How to use this License for your documents, Prev: Copying This Manual, Up: About this manual + | +8.6.2 How to use this License for your documents | +------------------------------------------------ | + | +To use this License in a document you have written, include a copy of | +the License in the document and put the following copyright and license | +notices just after the title page: | + | + Copyright (C) YEAR YOUR NAME. | + Permission is granted to copy, distribute and/or modify this document | + under the terms of the GNU Free Documentation License, Version 1.2 | + or any later version published by the Free Software Foundation; | + with no Invariant Sections, no Front-Cover Texts, and no Back-Cover | + Texts.
