GNU Free Documentation License</A ></H1 ><P > <P CLASS="LITERALLAYOUT" > GNU Free Documentation License<br> Version 1.1, March 2000<br> <br> Copyright (C) 2000 Free Software Foundation, Inc.<br> 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA<br> Everyone is permitted to copy and distribute verbatim copies<br> of this license document, but changing it is not allowed.<br> <br> <br> 0. PREAMBLE<br> <br> The purpose of this License is to make a manual, textbook, or other<br> written document "free" in the sense of freedom: to assure everyone<br> the effective freedom to copy and redistribute it, with or without<br> modifying it, either commercially or noncommercially. Secondarily,<br> this License preserves for the author and publisher a way to get<br> credit for their work, while not being considered responsible for<br> modifications made by others.<br> <br> This License is a kind of "copyleft", which means that derivative<br> works of the document must themselves be free in the same sense. It<br> complements the GNU General Public License, which is a copyleft<br> license designed for free software.<br> <br> We have designed this License in order to use it for manuals for free<br> software, because free software needs free documentation: a free<br> program should come with manuals providing the same freedoms that the<br> software does. But this License is not limited to software manuals;<br> it can be used for any textual work, regardless of subject matter or<br> whether it is published as a printed book. We recommend this License<br> principally for works whose purpose is instruction or reference.<br> <br> <br> 1. APPLICABILITY AND DEFINITIONS<br> <br> This License applies to any manual or other work that contains a<br> notice placed by the copyright holder saying it can be distributed<br> under the terms of this License. The "Document", below, refers to any<br> such manual or work. Any member of the public is a licensee, and is<br> addressed as "you".<br> <br> A "Modified Version" of the Document means any work containing the<br> Document or a portion of it, either copied verbatim, or with<br> modifications and/or translated into another language.<br> <br> A "Secondary Section" is a named appendix or a front-matter section of<br> the Document that deals exclusively with the relationship of the<br> publishers or authors of the Document to the Document's overall subject<br> (or to related matters) and contains nothing that could fall directly<br> within that overall subject. (For example, if the Document is in part a<br> textbook of mathematics, a Secondary Section may not explain any<br> mathematics.) The relationship could be a matter of historical<br> connection with the subject or with related matters, or of legal,<br> commercial, philosophical, ethical or political position regarding<br> them.<br> <br> The "Invariant Sections" are certain Secondary Sections whose titles<br> are designated, as being those of Invariant Sections, in the notice<br> that says that the Document is released under this License.<br> <br> The "Cover Texts" are certain short passages of text that are listed,<br> as Front-Cover Texts or Back-Cover Texts, in the notice that says that<br> the Document is released under this License.<br> <br> A "Transparent" copy of the Document means a machine-readable copy,<br> represented in a format whose specification is available to the<br> general public, whose contents can be viewed and edited directly and<br> straightforwardly with generic text editors or (for images composed of<br> pixels) generic paint programs or (for drawings) some widely available<br> drawing editor, and that is suitable for input to text formatters or<br> for automatic translation to a variety of formats suitable for input<br> to text formatters. A copy made in an otherwise Transparent file<br> format whose markup has been designed to thwart or discourage<br> subsequent modification by readers is not Transparent. A copy that is<br> not "Transparent" is called "Opaque".<br> <br> Examples of suitable formats for Transparent copies include plain<br> ASCII without markup, Texinfo input format, LaTeX input format, SGML<br> or XML using a publicly available DTD, and standard-conforming simple<br> HTML designed for human modification. Opaque formats include<br> PostScript, PDF, proprietary formats that can be read and edited only<br> by proprietary word processors, SGML or XML for which the DTD and/or<br> processing tools are not generally available, and the<br> machine-generated HTML produced by some word processors for output<br> purposes only.<br> <br> The "Title Page" means, for a printed book, the title page itself,<br> plus such following pages as are needed to hold, legibly, the material<br> this License requires to appear in the title page. For works in<br> formats which do not have any title page as such, "Title Page" means<br> the text near the most prominent appearance of the work's title,<br> preceding the beginning of the body of the text.<br> <br> <br> 2. VERBATIM COPYING<br> <br> You may copy and distribute the Document in any medium, either<br> commercially or noncommercially, provided that this License, the<br> copyright notices, and the license notice saying this License applies<br> to the Document are reproduced in all copies, and that you add no other<br> conditions whatsoever to those of this License. You may not use<br> technical measures to obstruct or control the reading or further<br> copying of the copies you make or distribute. However, you may accept<br> compensation in exchange for copies. If you distribute a large enough<br> number of copies you must also follow the conditions in section 3.<br> <br> You may also lend copies, under the same conditions stated above, and<br> you may publicly display copies.<br> <br> <br> 3. COPYING IN QUANTITY<br> <br> If you publish printed copies of the Document numbering more than 100,<br> and the Document's license notice requires Cover Texts, you must enclose<br> the copies in covers that carry, clearly and legibly, all these Cover<br> Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on<br> the back cover. Both covers must also clearly and legibly identify<br> you as the publisher of these copies. The front cover must present<br> the full title with all words of the title equally prominent and<br> visible. You may add other material on the covers in addition.<br> Copying with changes limited to the covers, as long as they preserve<br> the title of the Document and satisfy these conditions, can be treated<br> as verbatim copying in other respects.<br> <br> If the required texts for either cover are too voluminous to fit<br> legibly, you should put the first ones listed (as many as fit<br> reasonably) on the actual cover, and continue the rest onto adjacent<br> pages.<br> <br> If you publish or distribute Opaque copies of the Document numbering<br> more than 100, you must either include a machine-readable Transparent<br> copy along with each Opaque copy, or state in or with each Opaque copy<br> a publicly-accessible computer-network location containing a complete<br> Transparent copy of the Document, free of added material, which the<br> general network-using public has access to download anonymously at no<br> charge using public-standard network protocols. If you use the latter<br> option, you must take reasonably prudent steps, when you begin<br> distribution of Opaque copies in quantity, to ensure that this<br> Transparent copy will remain thus accessible at the stated location<br> until at least one year after the last time you distribute an Opaque<br> copy (directly or through your agents or retailers) of that edition to<br> the public.<br> <br> It is requested, but not required, that you contact the authors of the<br> Document well before redistributing any large number of copies, to give<br> them a chance to provide you with an updated version of the Document.<br> <br> <br> 4. MODIFICATIONS<br> <br> You may copy and distribute a Modified Version of the Document under<br> the conditions of sections 2 and 3 above, provided that you release<br> the Modified Version under precisely this License, with the Modified<br> Version filling the role of the Document, thus licensing distribution<br> and modification of the Modified Version to whoever possesses a copy<br> of it. In addition, you must do these things in the Modified Version:<br> <br> A. Use in the Title Page (and on the covers, if any) a title distinct<br> from that of the Document, and from those of previous versions<br> (which should, if there were any, be listed in the History section<br> of the Document). You may use the same title as a previous version<br> if the original publisher of that version gives permission.<br> B. List on the Title Page, as authors, one or more persons or entities<br> responsible for authorship of the modifications in the Modified<br> Version, together with at least five of the principal authors of the<br> Document (all of its principal authors, if it has less than five).<br> C. State on the Title page the name of the publisher of the<br> Modified Version, as the publisher.<br> D. Preserve all the copyright notices of the Document.<br> E. Add an appropriate copyright notice for your modifications<br> adjacent to the other copyright notices.<br> F. Include, immediately after the copyright notices, a license notice<br> giving the public permission to use the Modified Version under the<br> terms of this License, in the form shown in the Addendum below.<br> G. Preserve in that license notice the full lists of Invariant Sections<br> and required Cover Texts given in the Document's license notice.<br> H. Include an unaltered copy of this License.<br> I. Preserve the section entitled "History", and its title, and add to<br> it an item stating at least the title, year, new authors, and<br> publisher of the Modified Version as given on the Title Page. If<br> there is no section entitled "History" in the Document, create one<br> stating the title, year, authors, and publisher of the Document as<br> given on its Title Page, then add an item describing the Modified<br> Version as stated in the previous sentence.<br> J. Preserve the network location, if any, given in the Document for<br> public access to a Transparent copy of the Document, and likewise<br> the network locations given in the Document for previous versions<br> it was based on. These may be placed in the "History" section.<br> You may omit a network location for a work that was published at<br> least four years before the Document itself, or if the original<br> publisher of the version it refers to gives permission.<br> K. In any section entitled "Acknowledgements" or "Dedications",<br> preserve the section's title, and preserve in the section all the<br> substance and tone of each of the contributor acknowledgements<br> and/or dedications given therein.<br> L. Preserve all the Invariant Sections of the Document,<br> unaltered in their text and in their titles. Section numbers<br> or the equivalent are not considered part of the section titles.<br> M. Delete any section entitled "Endorsements". Such a section<br> may not be included in the Modified Version.<br> N. Do not retitle any existing section as "Endorsements"<br> or to conflict in title with any Invariant Section.<br> <br> If the Modified Version includes new front-matter sections or<br> appendices that qualify as Secondary Sections and contain no material<br> copied from the Document, you may at your option designate some or all<br> of these sections as invariant. To do this, add their titles to the<br> list of Invariant Sections in the Modified Version's license notice.<br> These titles must be distinct from any other section titles.<br> <br> You may add a section entitled "Endorsements", provided it contains<br> nothing but endorsements of your Modified Version by various<br> parties--for example, statements of peer review or that the text has<br> been approved by an organization as the authoritative definition of a<br> standard.<br> <br> You may add a passage of up to five words as a Front-Cover Text, and a<br> passage of up to 25 words as a Back-Cover Text, to the end of the list<br> of Cover Texts in the Modified Version. Only one passage of<br> Front-Cover Text and one of Back-Cover Text may be added by (or<br> through arrangements made by) any one entity. If the Document already<br> includes a cover text for the same cover, previously added by you or<br> by arrangement made by the same entity you are acting on behalf of,<br> you may not add another; but you may replace the old one, on explicit<br> permission from the previous publisher that added the old one.<br> <br> The author(s) and publisher(s) of the Document do not by this License<br> give permission to use their names for publicity for or to assert or<br> imply endorsement of any Modified Version.<br> <br> <br> 5. COMBINING DOCUMENTS<br> <br> You may combine the Document with other documents released under this<br> License, under the terms defined in section 4 above for modified<br> versions, provided that you include in the combination all of the<br> Invariant Sections of all of the original documents, unmodified, and<br> list them all as Invariant Sections of your combined work in its<br> license notice.<br> <br> The combined work need only contain one copy of this License, and<br> multiple identical Invariant Sections may be replaced with a single<br> copy. If there are multiple Invariant Sections with the same name but<br> different contents, make the title of each such section unique by<br> adding at the end of it, in parentheses, the name of the original<br> author or publisher of that section if known, or else a unique number.<br> Make the same adjustment to the section titles in the list of<br> Invariant Sections in the license notice of the combined work.<br> <br> In the combination, you must combine any sections entitled "History"<br> in the various original documents, forming one section entitled<br> "History"; likewise combine any sections entitled "Acknowledgements",<br> and any sections entitled "Dedications". You must delete all sections<br> entitled "Endorsements."<br> <br> <br> 6. COLLECTIONS OF DOCUMENTS<br> <br> You may make a collection consisting of the Document and other documents<br> released under this License, and replace the individual copies of this<br> License in the various documents with a single copy that is included in<br> the collection, provided that you follow the rules of this License for<br> verbatim copying of each of the documents in all other respects.<br> <br> You may extract a single document from such a collection, and distribute<br> it individually under this License, provided you insert a copy of this<br> License into the extracted document, and follow this License in all<br> other respects regarding verbatim copying of that document.<br> <br> <br> <br> 7. AGGREGATION WITH INDEPENDENT WORKS<br> <br> A compilation of the Document or its derivatives with other separate<br> and independent documents or works, in or on a volume of a storage or<br> distribution medium, does not as a whole count as a Modified Version<br> of the Document, provided no compilation copyright is claimed for the<br> compilation. Such a compilation is called an "aggregate", and this<br> License does not apply to the other self-contained works thus compiled<br> with the Document, on account of their being thus compiled, if they<br> are not themselves derivative works of the Document.<br> <br> If the Cover Text requirement of section 3 is applicable to these<br> copies of the Document, then if the Document is less than one quarter<br> of the entire aggregate, the Document's Cover Texts may be placed on<br> covers that surround only the Document within the aggregate.<br> Otherwise they must appear on covers around the whole aggregate.<br> <br> <br> 8. TRANSLATION<br> <br> Translation is considered a kind of modification, so you may<br> distribute translations of the Document under the terms of section 4.<br> Replacing Invariant Sections with translations requires special<br> permission from their copyright holders, but you may include<br> translations of some or all Invariant Sections in addition to the<br> original versions of these Invariant Sections. You may include a<br> translation of this License provided that you also include the<br> original English version of this License. In case of a disagreement<br> between the translation and the original English version of this<br> License, the original English version will prevail.<br> <br> <br> 9. TERMINATION<br> <br> You may not copy, modify, sublicense, or distribute the Document except<br> as expressly provided for under this License. Any other attempt to<br> copy, modify, sublicense or distribute the Document is void, and will<br> automatically terminate your rights under this License. However,<br> parties who have received copies, or rights, from you under this<br> License will not have their licenses terminated so long as such<br> parties remain in full compliance.<br> <br> <br> 10. FUTURE REVISIONS OF THIS LICENSE<br> <br> The Free Software Foundation may publish new, revised versions<br> of the GNU Free Documentation License from time to time. Such new<br> versions will be similar in spirit to the present version, but may<br> differ in detail to address new problems or concerns. See<br> http:///www.gnu.org/copyleft/.<br> <br> Each version of the License is given a distinguishing version number.<br> If the Document specifies that a particular numbered version of this<br> License "or any later version" applies to it, you have the option of<br> following the terms and conditions either of that specified version or<br> of any later version that has been published (not as a draft) by the<br> Free Software Foundation. If the Document does not specify a version<br> number of this License, you may choose any version ever published (not<br> as a draft) by the Free Software Foundation.<br> <br> <br> ADDENDUM: How to use this License for your documents<br> <br> To use this License in a document you have written, include a copy of<br> the License in the document and put the following copyright and<br> license notices just after the title page:<br> <br> Copyright (c) YEAR YOUR NAME.<br> Permission is granted to copy, distribute and/or modify this document<br> under the terms of the GNU Free Documentation License, Version 1.1<br> or any later version published by the Free Software Foundation;<br> with the Invariant Sections being LIST THEIR TITLES, with the<br> Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST.<br> A copy of the license is included in the section entitled "GNU<br> Free Documentation License".<br> <br> If you have no Invariant Sections, write "with no Invariant Sections"<br> instead of saying which ones are invariant. If you have no<br> Front-Cover Texts, write "no Front-Cover Texts" instead of<br> "Front-Cover Texts being LIST"; likewise for Back-Cover Texts.<br> <br> If your document contains nontrivial examples of program code, we<br> recommend releasing these examples in parallel under your choice of<br> free software license, such as the GNU General Public License,<br> to permit their use in free software.<br> <br> </P > </P ></DIV ><DIV CLASS="NAVFOOTER" ><HR ALIGN="LEFT" WIDTH="100%"><TABLE WIDTH="100%" BORDER="0" CELLPADDING="0" CELLSPACING="0" ><TR ><TD WIDTH="33%" ALIGN="left" VALIGN="top" ><A HREF="install-catalog.html" >Prev</A ></TD ><TD WIDTH="34%" ALIGN="center" VALIGN="top" ><A HREF="index.html" >Home</A ></TD ><TD WIDTH="33%" ALIGN="right" VALIGN="top" > </TD ></TR ><TR ><TD WIDTH="33%" ALIGN="left" VALIGN="top" >install-catalog</TD ><TD WIDTH="34%" ALIGN="center" VALIGN="top" > </TD ><TD WIDTH="33%" ALIGN="right" VALIGN="top" > </TD ></TR ></TABLE ></DIV ></BODY ></HTML >
