License</H1 ><P >GNU Free Documentation License</P ><P >Version 1.2, November 2002</P ><P ></P ><P ></P ><P >Copyright (C) 2000,2001,2002 Free Software Foundation, Inc.</P ><P >51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA</P ><P >Everyone is permitted to copy and distribute verbatim copies</P ><P >of this license document, but changing it is not allowed.</P ><P ></P ><P ></P ><P >0. PREAMBLE</P ><P ></P ><P >The purpose of this License is to make a manual, textbook, or other</P ><P >functional and useful document "free" in the sense of freedom: to</P ><P >assure everyone the effective freedom to copy and redistribute it,</P ><P >with or without modifying it, either commercially or noncommercially.</P ><P >Secondarily, this License preserves for the author and publisher a way</P ><P >to get credit for their work, while not being considered responsible</P ><P >for modifications made by others.</P ><P ></P ><P >This License is a kind of "copyleft", which means that derivative</P ><P >works of the document must themselves be free in the same sense. It</P ><P >complements the GNU General Public License, which is a copyleft</P ><P >license designed for free software.</P ><P ></P ><P >We have designed this License in order to use it for manuals for free</P ><P >software, because free software needs free documentation: a free</P ><P >program should come with manuals providing the same freedoms that the</P ><P >software does. But this License is not limited to software manuals;</P ><P >it can be used for any textual work, regardless of subject matter or</P ><P >whether it is published as a printed book. We recommend this License</P ><P >principally for works whose purpose is instruction or reference.</P ><P ></P ><P ></P ><P >1. APPLICABILITY AND DEFINITIONS</P ><P ></P ><P >This License applies to any manual or other work, in any medium, that</P ><P >contains a notice placed by the copyright holder saying it can be</P ><P >distributed under the terms of this License. Such a notice grants a</P ><P >world-wide, royalty-free license, unlimited in duration, to use that</P ><P >work under the conditions stated herein. The "Document", below,</P ><P >refers to any such manual or work. Any member of the public is a</P ><P >licensee, and is addressed as "you". You accept the license if you</P ><P >copy, modify or distribute the work in a way requiring permission</P ><P >under copyright law.</P ><P ></P ><P >A "Modified Version" of the Document means any work containing the</P ><P >Document or a portion of it, either copied verbatim, or with</P ><P >modifications and/or translated into another language.</P ><P ></P ><P >A "Secondary Section" is a named appendix or a front-matter section of</P ><P >the Document that deals exclusively with the relationship of the</P ><P >publishers or authors of the Document to the Document's overall subject</P ><P >(or to related matters) and contains nothing that could fall directly</P ><P >within that overall subject. (Thus, if the Document is in part a</P ><P >textbook of mathematics, a Secondary Section may not explain any</P ><P >mathematics.) The relationship could be a matter of historical</P ><P >connection with the subject or with related matters, or of legal,</P ><P >commercial, philosophical, ethical or political position regarding</P ><P >them.</P ><P ></P ><P >The "Invariant Sections" are certain Secondary Sections whose titles</P ><P >are designated, as being those of Invariant Sections, in the notice</P ><P >that says that the Document is released under this License. If a</P ><P >section does not fit the above definition of Secondary then it is not</P ><P >allowed to be designated as Invariant. The Document may contain zero</P ><P >Invariant Sections. If the Document does not identify any Invariant</P ><P >Sections then there are none.</P ><P ></P ><P >The "Cover Texts" are certain short passages of text that are listed,</P ><P >as Front-Cover Texts or Back-Cover Texts, in the notice that says that</P ><P >the Document is released under this License. A Front-Cover Text may</P ><P >be at most 5 words, and a Back-Cover Text may be at most 25 words.</P ><P ></P ><P >A "Transparent" copy of the Document means a machine-readable copy,</P ><P >represented in a format whose specification is available to the</P ><P >general public, that is suitable for revising the document</P ><P >straightforwardly with generic text editors or (for images composed of</P ><P >pixels) generic paint programs or (for drawings) some widely available</P ><P >drawing editor, and that is suitable for input to text formatters or</P ><P >for automatic translation to a variety of formats suitable for input</P ><P >to text formatters. A copy made in an otherwise Transparent file</P ><P >format whose markup, or absence of markup, has been arranged to thwart</P ><P >or discourage subsequent modification by readers is not Transparent.</P ><P >An image format is not Transparent if used for any substantial amount</P ><P >of text. A copy that is not "Transparent" is called "Opaque".</P ><P ></P ><P >Examples of suitable formats for Transparent copies include plain</P ><P >ASCII without markup, Texinfo input format, LaTeX input format, SGML</P ><P >or XML using a publicly available DTD, and standard-conforming simple</P ><P >HTML, PostScript or PDF designed for human modification. Examples of</P ><P >transparent image formats include PNG, XCF and JPG. Opaque formats</P ><P >include proprietary formats that can be read and edited only by</P ><P >proprietary word processors, SGML or XML for which the DTD and/or</P ><P >processing tools are not generally available, and the</P ><P >machine-generated HTML, PostScript or PDF produced by some word</P ><P >processors for output purposes only.</P ><P ></P ><P >The "Title Page" means, for a printed book, the title page itself,</P ><P >plus such following pages as are needed to hold, legibly, the material</P ><P >this License requires to appear in the title page. For works in</P ><P >formats which do not have any title page as such, "Title Page" means</P ><P >the text near the most prominent appearance of the work's title,</P ><P >preceding the beginning of the body of the text.</P ><P ></P ><P >A section "Entitled XYZ" means a named subunit of the Document whose</P ><P >title either is precisely XYZ or contains XYZ in parentheses following</P ><P >text that translates XYZ in another language. (Here XYZ stands for a</P ><P >specific section name mentioned below, such as "Acknowledgements",</P ><P >"Dedications", "Endorsements", or "History".) To "Preserve the Title"</P ><P >of such a section when you modify the Document means that it remains a</P ><P >section "Entitled XYZ" according to this definition.</P ><P ></P ><P >The Document may include Warranty Disclaimers next to the notice which</P ><P >states that this License applies to the Document. These Warranty</P ><P >Disclaimers are considered to be included by reference in this</P ><P >License, but only as regards disclaiming warranties: any other</P ><P >implication that these Warranty Disclaimers may have is void and has</P ><P >no effect on the meaning of this License.</P ><P ></P ><P ></P ><P >2. VERBATIM COPYING</P ><P ></P ><P >You may copy and distribute the Document in any medium, either</P ><P >commercially or noncommercially, provided that this License, the</P ><P >copyright notices, and the license notice saying this License applies</P ><P >to the Document are reproduced in all copies, and that you add no other</P ><P >conditions whatsoever to those of this License. You may not use</P ><P >technical measures to obstruct or control the reading or further</P ><P >copying of the copies you make or distribute. However, you may accept</P ><P >compensation in exchange for copies. If you distribute a large enough</P ><P >number of copies you must also follow the conditions in section 3.</P ><P ></P ><P >You may also lend copies, under the same conditions stated above, and</P ><P >you may publicly display copies.</P ><P ></P ><P ></P ><P >3. COPYING IN QUANTITY</P ><P ></P ><P >If you publish printed copies (or copies in media that commonly have</P ><P >printed covers) of the Document, numbering more than 100, and the</P ><P >Document's license notice requires Cover Texts, you must enclose the</P ><P >copies in covers that carry, clearly and legibly, all these Cover</P ><P >Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on</P ><P >the back cover. Both covers must also clearly and legibly identify</P ><P >you as the publisher of these copies. The front cover must present</P ><P >the full title with all words of the title equally prominent and</P ><P >visible. You may add other material on the covers in addition.</P ><P >Copying with changes limited to the covers, as long as they preserve</P ><P >the title of the Document and satisfy these conditions, can be treated</P ><P >as verbatim copying in other respects.</P ><P ></P ><P >If the required texts for either cover are too voluminous to fit</P ><P >legibly, you should put the first ones listed (as many as fit</P ><P >reasonably) on the actual cover, and continue the rest onto adjacent</P ><P >pages.</P ><P ></P ><P >If you publish or distribute Opaque copies of the Document numbering</P ><P >more than 100, you must either include a machine-readable Transparent</P ><P >copy along with each Opaque copy, or state in or with each Opaque copy</P ><P >a computer-network location from which the general network-using</P ><P >public has access to download using public-standard network protocols</P ><P >a complete Transparent copy of the Document, free of added material.</P ><P >If you use the latter option, you must take reasonably prudent steps,</P ><P >when you begin distribution of Opaque copies in quantity, to ensure</P ><P >that this Transparent copy will remain thus accessible at the stated</P ><P >location until at least one year after the last time you distribute an</P ><P >Opaque copy (directly or through your agents or retailers) of that</P ><P >edition to the public.</P ><P ></P ><P >It is requested, but not required, that you contact the authors of the</P ><P >Document well before redistributing any large number of copies, to give</P ><P >them a chance to provide you with an updated version of the Document.</P ><P ></P ><P ></P ><P >4. MODIFICATIONS</P ><P ></P ><P >You may copy and distribute a Modified Version of the Document under</P ><P >the conditions of sections 2 and 3 above, provided that you release</P ><P >the Modified Version under precisely this License, with the Modified</P ><P >Version filling the role of the Document, thus licensing distribution</P ><P >and modification of the Modified Version to whoever possesses a copy</P ><P >of it. In addition, you must do these things in the Modified Version:</P ><P ></P ><P >A. Use in the Title Page (and on the covers, if any) a title distinct</P ><P >from that of the Document, and from those of previous versions</P ><P >(which should, if there were any, be listed in the History section</P ><P >of the Document). You may use the same title as a previous version</P ><P >if the original publisher of that version gives permission.</P ><P >B. List on the Title Page, as authors, one or more persons or entities</P ><P >responsible for authorship of the modifications in the Modified</P ><P >Version, together with at least five of the principal authors of the</P ><P >Document (all of its principal authors, if it has fewer than five),</P ><P >unless they release you from this requirement.</P ><P >C. State on the Title page the name of the publisher of the</P ><P >Modified Version, as the publisher.</P ><P >D. Preserve all the copyright notices of the Document.</P ><P >E. Add an appropriate copyright notice for your modifications</P ><P >adjacent to the other copyright notices.</P ><P >F. Include, immediately after the copyright notices, a license notice</P ><P >giving the public permission to use the Modified Version under the</P ><P >terms of this License, in the form shown in the Addendum below.</P ><P >G. Preserve in that license notice the full lists of Invariant Sections</P ><P >and required Cover Texts given in the Document's license notice.</P ><P >H. Include an unaltered copy of this License.</P ><P >I. Preserve the section Entitled "History", Preserve its Title, and add</P ><P >to it an item stating at least the title, year, new authors, and</P ><P >publisher of the Modified Version as given on the Title Page. If</P ><P >there is no section Entitled "History" in the Document, create one</P ><P >stating the title, year, authors, and publisher of the Document as</P ><P >given on its Title Page, then add an item describing the Modified</P ><P >Version as stated in the previous sentence.</P ><P >J. Preserve the network location, if any, given in the Document for</P ><P >public access to a Transparent copy of the Document, and likewise</P ><P >the network locations given in the Document for previous versions</P ><P >it was based on. These may be placed in the "History" section.</P ><P >You may omit a network location for a work that was published at</P ><P >least four years before the Document itself, or if the original</P ><P >publisher of the version it refers to gives permission.</P ><P >K. For any section Entitled "Acknowledgements" or "Dedications",</P ><P >Preserve the Title of the section, and preserve in the section all</P ><P >the substance and tone of each of the contributor acknowledgements</P ><P >and/or dedications given therein.</P ><P >L. Preserve all the Invariant Sections of the Document,</P ><P >unaltered in their text and in their titles. Section numbers</P ><P >or the equivalent are not considered part of the section titles.</P ><P >M. Delete any section Entitled "Endorsements". Such a section</P ><P >may not be included in the Modified Version.</P ><P >N. Do not retitle any existing section to be Entitled "Endorsements"</P ><P >or to conflict in title with any Invariant Section.</P ><P >O. Preserve any Warranty Disclaimers.</P ><P ></P ><P >If the Modified Version includes new front-matter sections or</P ><P >appendices that qualify as Secondary Sections and contain no material</P ><P >copied from the Document, you may at your option designate some or all</P ><P >of these sections as invariant. To do this, add their titles to the</P ><P >list of Invariant Sections in the Modified Version's license notice.</P ><P >These titles must be distinct from any other section titles.</P ><P ></P ><P >You may add a section Entitled "Endorsements", provided it contains</P ><P >nothing but endorsements of your Modified Version by various</P ><P >parties--for example, statements of peer review or that the text has</P ><P >been approved by an organization as the authoritative definition of a</P ><P >standard.</P ><P ></P ><P >You may add a passage of up to five words as a Front-Cover Text, and a</P ><P >passage of up to 25 words as a Back-Cover Text, to the end of the list</P ><P >of Cover Texts in the Modified Version. Only one passage of</P ><P >Front-Cover Text and one of Back-Cover Text may be added by (or</P ><P >through arrangements made by) any one entity. If the Document already</P ><P >includes a cover text for the same cover, previously added by you or</P ><P >by arrangement made by the same entity you are acting on behalf of,</P ><P >you may not add another; but you may replace the old one, on explicit</P ><P >permission from the previous publisher that added the old one.</P ><P ></P ><P >The author(s) and publisher(s) of the Document do not by this License</P ><P >give permission to use their names for publicity for or to assert or</P ><P >imply endorsement of any Modified Version.</P ><P ></P ><P ></P ><P >5. COMBINING DOCUMENTS</P ><P ></P ><P >You may combine the Document with other documents released under this</P ><P >License, under the terms defined in section 4 above for modified</P ><P >versions, provided that you include in the combination all of the</P ><P >Invariant Sections of all of the original documents, unmodified, and</P ><P >list them all as Invariant Sections of your combined work in its</P ><P >license notice, and that you preserve all their Warranty Disclaimers.</P ><P ></P ><P >The combined work need only contain one copy of this License, and</P ><P >multiple identical Invariant Sections may be replaced with a single</P ><P >copy. If there are multiple Invariant Sections with the same name but</P ><P >different contents, make the title of each such section unique by</P ><P >adding at the end of it, in parentheses, the name of the original</P ><P >author or publisher of that section if known, or else a unique number.</P ><P >Make the same adjustment to the section titles in the list of</P ><P >Invariant Sections in the license notice of the combined work.</P ><P ></P ><P >In the combination, you must combine any sections Entitled "History"</P ><P >in the various original documents, forming one section Entitled</P ><P >"History"; likewise combine any sections Entitled "Acknowledgements",</P ><P >and any sections Entitled "Dedications". You must delete all sections</P ><P >Entitled "Endorsements".</P ><P ></P ><P ></P ><P >6. COLLECTIONS OF DOCUMENTS</P ><P ></P ><P >You may make a collection consisting of the Document and other documents</P ><P >released under this License, and replace the individual copies of this</P ><P >License in the various documents with a single copy that is included in</P ><P >the collection, provided that you follow the rules of this License for</P ><P >verbatim copying of each of the documents in all other respects.</P ><P ></P ><P >You may extract a single document from such a collection, and distribute</P ><P >it individually under this License, provided you insert a copy of this</P ><P >License into the extracted document, and follow this License in all</P ><P >other respects regarding verbatim copying of that document.</P ><P ></P ><P ></P ><P >7. AGGREGATION WITH INDEPENDENT WORKS</P ><P ></P ><P >A compilation of the Document or its derivatives with other separate</P ><P >and independent documents or works, in or on a volume of a storage or</P ><P >distribution medium, is called an "aggregate" if the copyright</P ><P >resulting from the compilation is not used to limit the legal rights</P ><P >of the compilation's users beyond what the individual works permit.</P ><P >When the Document is included in an aggregate, this License does not</P ><P >apply to the other works in the aggregate which are not themselves</P ><P >derivative works of the Document.</P ><P ></P ><P >If the Cover Text requirement of section 3 is applicable to these</P ><P >copies of the Document, then if the Document is less than one half of</P ><P >the entire aggregate, the Document's Cover Texts may be placed on</P ><P >covers that bracket the Document within the aggregate, or the</P ><P >electronic equivalent of covers if the Document is in electronic form.</P ><P >Otherwise they must appear on printed covers that bracket the whole</P ><P >aggregate.</P ><P ></P ><P ></P ><P >8. TRANSLATION</P ><P ></P ><P >Translation is considered a kind of modification, so you may</P ><P >distribute translations of the Document under the terms of section 4.</P ><P >Replacing Invariant Sections with translations requires special</P ><P >permission from their copyright holders, but you may include</P ><P >translations of some or all Invariant Sections in addition to the</P ><P >original versions of these Invariant Sections. You may include a</P ><P >translation of this License, and all the license notices in the</P ><P >Document, and any Warranty Disclaimers, provided that you also include</P ><P >the original English version of this License and the original versions</P ><P >of those notices and disclaimers. In case of a disagreement between</P ><P >the translation and the original version of this License or a notice</P ><P >or disclaimer, the original version will prevail.</P ><P ></P ><P >If a section in the Document is Entitled "Acknowledgements",</P ><P >"Dedications", or "History", the requirement (section 4) to Preserve</P ><P >its Title (section 1) will typically require changing the actual</P ><P >title.</P ><P ></P ><P ></P ><P >9. TERMINATION</P ><P ></P ><P >You may not copy, modify, sublicense, or distribute the Document except</P ><P >as expressly provided for under this License. Any other attempt to</P ><P >copy, modify, sublicense or distribute the Document is void, and will</P ><P >automatically terminate your rights under this License. However,</P ><P >parties who have received copies, or rights, from you under this</P ><P >License will not have their licenses terminated so long as such</P ><P >parties remain in full compliance.</P ><P ></P ><P ></P ><P >10. FUTURE REVISIONS OF THIS LICENSE</P ><P ></P ><P >The Free Software Foundation may publish new, revised versions</P ><P >of the GNU Free Documentation License from time to time. Such new</P ><P >versions will be similar in spirit to the present version, but may</P ><P >differ in detail to address new problems or concerns. See</P ><P >http://www.gnu.org/copyleft/.</P ><P ></P ><P >Each version of the License is given a distinguishing version number.</P ><P >If the Document specifies that a particular numbered version of this</P ><P >License "or any later version" applies to it, you have the option of</P ><P >following the terms and conditions either of that specified version or</P ><P >of any later version that has been published (not as a draft) by the</P ><P >Free Software Foundation. If the Document does not specify a version</P ><P >number of this License, you may choose any version ever published (not</P ><P >as a draft) by the Free Software Foundation.</P ><P ></P ><P ></P ><P >ADDENDUM: How to use this License for your documents</P ><P ></P ><P >To use this License in a document you have written, include a copy of</P ><P >the License in the document and put the following copyright and</P ><P >license notices just after the title page:</P ><P ></P ><P >Copyright (c) YEAR YOUR NAME.</P ><P >Permission is granted to copy, distribute and/or modify this document</P ><P >under the terms of the GNU Free Documentation License, Version 1.2</P ><P >or any later version published by the Free Software Foundation;</P ><P >with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts.</P ><P >A copy of the license is included in the section entitled "GNU</P ><P >Free Documentation License".</P ><P ></P ><P >If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,</P ><P >replace the "with...Texts." line with this:</P ><P ></P ><P >with the Invariant Sections being LIST THEIR TITLES, with the</P ><P >Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST.</P ><P ></P ><P >If you have Invariant Sections without Cover Texts, or some other</P ><P >combination of the three, merge those two alternatives to suit the</P ><P >situation.</P ><P ></P ><P >If your document contains nontrivial examples of program code, we</P ><P >recommend releasing these examples in parallel under your choice of</P ><P >free software license, such as the GNU General Public License,</P ><P >to permit their use in free software.</P ></DIV ><DIV CLASS="NAVFOOTER" ><HR ALIGN="LEFT" WIDTH="100%"><TABLE SUMMARY="Footer navigation table" WIDTH="100%" BORDER="0" CELLPADDING="0" CELLSPACING="0" ><TR ><TD WIDTH="33%" ALIGN="left" VALIGN="top" ><A HREF="x219.html" ACCESSKEY="P" >Prev</A ></TD ><TD WIDTH="34%" ALIGN="center" VALIGN="top" ><A HREF="index.html" ACCESSKEY="H" >Home</A ></TD ><TD WIDTH="33%" ALIGN="right" VALIGN="top" > </TD ></TR ><TR ><TD WIDTH="33%" ALIGN="left" VALIGN="top" >Copyright</TD ><TD WIDTH="34%" ALIGN="center" VALIGN="top" > </TD ><TD WIDTH="33%" ALIGN="right" VALIGN="top" > </TD ></TR ></TABLE ></DIV ></BODY ></HTML >
