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. -\" .PP -\" 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. -\" .PP -\" 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. -\" .PP -\" 1. APPLICABILITY AND DEFINITIONS -\" .PP -\" This License applies to any manual or other work that contains a -\" notice placed by the copyright holder saying it can be distributed -\" under the terms of this License. The "Document", below, refers to any -\" such manual or work. Any member of the public is a licensee, and is -\" addressed as "you". -\" .PP -\" 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. -\" .PP -\" 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. (For example, 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. -\" .PP -\" 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. -\" .PP -\" 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. -\" .PP -\" A "Transparent" copy of the Document means a machine-readable copy, -\" represented in a format whose specification is available to the -\" general public, whose contents can be viewed and edited directly and -\" 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 has been designed to thwart or discourage -\" subsequent modification by readers is not Transparent. A copy that is -\" not "Transparent" is called "Opaque". -\" .PP -\" 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 designed for human modification. Opaque formats include -\" PostScript, PDF, 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 produced by some word processors for output -\" purposes only. -\" .PP -\" 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. -\" .PP -\" 2. VERBATIM COPYING -\" .PP -\" 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. -\" .PP -\" You may also lend copies, under the same conditions stated above, and -\" you may publicly display copies. -\" .PP -\" 3. COPYING IN QUANTITY -\" .PP -\" If you publish printed copies 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. -\" .PP -\" 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. -\" .PP -\" 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 publicly-accessible computer-network location containing a complete -\" Transparent copy of the Document, free of added material, which the -\" general network-using public has access to download anonymously at no -\" charge using public-standard network protocols. 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. -\" .PP -\" 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. -\" .PP -\" 4. MODIFICATIONS -\" .PP -\" 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: -\" .PP -\" 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).

Include an unaltered copy of this License. -\" .PP -\" I. Preserve the section entitled "History", and 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.

In any section entitled "Acknowledgements" or "Dedications", -\" preserve the section's title, and preserve in the section all the -\" substance and tone of each of the contributor acknowledgements -\" and/or dedications given therein. -\" .PP -\" 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. -\" .PP -\" M. Delete any section entitled "Endorsements". Such a section -\" may not be included in the Modified Version. -\" .PP -\" N. Do not retitle any existing section as "Endorsements" -\" or to conflict in title with any Invariant Section. -\" .PP -\" 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. -\" .PP -\" 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. -\" .PP -\" 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.

COMBINING DOCUMENTS -\" .PP -\" 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. -\" .PP -\" 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. -\" .PP -\" 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." -\" .PP - -\" 6. COLLECTIONS OF DOCUMENTS -\" .PP -\" 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. -\" .PP -\" 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. -\" .PP - -\" 7. AGGREGATION WITH INDEPENDENT WORKS -\" .PP -\" 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, does not as a whole count as a Modified Version -\" of the Document, provided no compilation copyright is claimed for the -\" compilation. Such a compilation is called an "aggregate", and this -\" License does not apply to the other self-contained works thus compiled -\" with the Document, on account of their being thus compiled, if they -\" are not themselves derivative works of the Document. -\" .PP -\" If the Cover Text requirement of section 3 is applicable to these -\" copies of the Document, then if the Document is less than one quarter -\" of the entire aggregate, the Document's Cover Texts may be placed on -\" covers that surround only the Document within the aggregate. -\" Otherwise they must appear on covers around the whole aggregate. -\" .PP - -\" 8. TRANSLATION -\" .PP -\" 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 provided that you also include the -\" original English version of this License. In case of a disagreement -\" between the translation and the original English version of this -\" License, the original English version will prevail. -\" .PP - -\" 9. TERMINATION -\" .PP -\" 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. -\" .PP - -\" 10. FUTURE REVISIONS OF THIS LICENSE -\" .PP -\" The Free Software Foundation may publish new, revised versions -\" of the GNU Free Documentation License from time to time.

That license is described in the -sources for this manual page, but it is not displayed here in order to -make this manual more consise. Copies of this license can also be -obtained from: http://www.gnu.org/copyleft/. - -\" .SH GNU Free Documentation License -\" Version 1.1, March 2000 - -\" Copyright (C) 2000 Free Software Foundation, Inc. -\" 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA - -\" Everyone is permitted to copy and distribute verbatim -\" copies of this license document, but changing it is -\" not allowed. -\" .PP -\" 0. PREAMBLE -\" .PP -\" The purpose of this License is to make a manual, textbook, or other -\" written 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. -\" .PP -\" 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. -\" .PP -\" 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. -\" .PP -\" 1. APPLICABILITY AND DEFINITIONS -\" .PP -\" This License applies to any manual or other work that contains a -\" notice placed by the copyright holder saying it can be distributed -\" under the terms of this License. The "Document", below, refers to any -\" such manual or work. Any member of the public is a licensee, and is -\" addressed as "you". -\" .PP -\" 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. -\" .PP -\" 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. (For example, 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. -\" .PP -\" 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. -\" .PP -\" 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. -\" .PP -\" A "Transparent" copy of the Document means a machine-readable copy, -\" represented in a format whose specification is available to the -\" general public, whose contents can be viewed and edited directly and -\" 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 has been designed to thwart or discourage -\" subsequent modification by readers is not Transparent. A copy that is -\" not "Transparent" is called "Opaque". -\" .PP -\" 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 designed for human modification. Opaque formats include -\" PostScript, PDF, 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 produced by some word processors for output -\" purposes only. -\" .PP -\" 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. -\" .PP -\" 2. VERBATIM COPYING -\" .PP -\" 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. -\" .PP -\" You may also lend copies, under the same conditions stated above, and -\" you may publicly display copies. -\" .PP -\" 3. COPYING IN QUANTITY -\" .PP -\" If you publish printed copies 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. -\" .PP -\" 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. -\" .PP -\" 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 publicly-accessible computer-network location containing a complete -\" Transparent copy of the Document, free of added material, which the -\" general network-using public has access to download anonymously at no -\" charge using public-standard network protocols. 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. -\" .PP -\" 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. -\" .PP -\" 4. MODIFICATIONS -\" .PP -\" 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: -\" .PP -\" 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. -\" .PP -\" 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 less than five). -\" .PP -\" C. State on the Title page the name of the publisher of the -\" Modified Version, as the publisher. -\" .PP -\" D. Preserve all the copyright notices of the Document. -\" .PP -\" E. Add an appropriate copyright notice for your modifications -\" adjacent to the other copyright notices. -\" .PP -\" 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. -\" Preserve in that license notice the full lists of Invariant Sections -\" and required Cover Texts given in the Document's license notice. -\" .PP -\" H. Include an unaltered copy of this License. -\" .PP -\" I. Preserve the section entitled "History", and 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. -\" .PP -\" 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. -\" .PP -\" K. In any section entitled "Acknowledgements" or "Dedications", -\" preserve the section's title, and preserve in the section all the -\" substance and tone of each of the contributor acknowledgements -\" and/or dedications given therein. -\" .PP -\" 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. -\" .PP -\" M. Delete any section entitled "Endorsements". Such a section -\" may not be included in the Modified Version. -\" .PP -\" N. Do not retitle any existing section as "Endorsements" -\" or to conflict in title with any Invariant Section. -\" .PP -\" 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. -\" .PP -\" 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. -\" .PP -\" 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. -\" .PP -\" 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. -\" .PP - -\" 5. COMBINING DOCUMENTS -\" .PP -\" 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. -\" .PP -\" 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. -\" .PP -\" 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." -\" .PP - -\" 6. COLLECTIONS OF DOCUMENTS -\" .PP -\" 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. -\" .PP -\" 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. -\" .PP - -\" 7. AGGREGATION WITH INDEPENDENT WORKS -\" .PP -\" 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, does not as a whole count as a Modified Version -\" of the Document, provided no compilation copyright is claimed for the -\" compilation. Such a compilation is called an "aggregate", and this -\" License does not apply to the other self-contained works thus compiled -\" with the Document, on account of their being thus compiled, if they -\" are not themselves derivative works of the Document. -\" .PP -\" If the Cover Text requirement of section 3 is applicable to these -\" copies of the Document, then if the Document is less than one quarter -\" of the entire aggregate, the Document's Cover Texts may be placed on -\" covers that surround only the Document within the aggregate. -\" Otherwise they must appear on covers around the whole aggregate. -\" .PP - -\" 8. TRANSLATION -\" .PP -\" 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 provided that you also include the -\" original English version of this License. In case of a disagreement -\" between the translation and the original English version of this -\" License, the original English version will prevail. -\" .PP - -\" 9. TERMINATION -\" .PP -\" 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. -\" .PP - -\" 10. FUTURE REVISIONS OF THIS LICENSE -\" .PP -\" 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/. -\" .PP -\" 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. -\" .PP - -\" ADDENDUM: How to use this License for your documents -\" .PP -\" 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: -\" .PP -\" 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 1.1 or any later -\" version published by the Free Software Foundation; -\" with the Invariant Sections being LIST THEIR TITLES, -\" with the Front-Cover Texts being LIST, and with the -\" Back-Cover Texts being LIST. A copy of the license -\" is included in the section entitled "GNU Free -\" Documentation License". -\" .PP -\" If you have no Invariant Sections, write "with no Invariant Sections" -\" instead of saying which ones are invariant. If you have no -\" Front-Cover Texts, write "no Front-Cover Texts" instead of -\" "Front-Cover Texts being LIST"; likewise for Back-Cover Texts. -\" .PP -\" If your document contains nontrivial examples of program code, we -\" recommend releasing these examples in parallel under your choice of -\" free software license, such as the GNU General Public License, -\" to permit their use in free software. +Permission is granted to copy, distribute and/or modify this document +under the terms of the \s-1GNU\s0 Free Documentation License, Version 1.1 +or any later version published by the Free Software Foundation; +with no Invariant Sections, with no Front-Cover Texts, and with no +Back-Cover Texts.
