\layout Standard

Everyone is permitted to copy and distribute verbatim copies of this license
 document, but changing it is not allowed.
\layout Subsection*

0.
 Preamble
\layout Standard

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.
\layout Standard

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.
\layout Standard

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.
\layout Subsection*

1.
 Applicability and Definitions
\layout Standard

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."
\layout Standard

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.
\layout Standard

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.
\layout Standard

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.
\layout Standard

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.
\layout Standard

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."
\layout Standard

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-ge
nerated HTML produced by some word processors for output purposes only.
\layout Standard

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.
\layout Subsection*

2.
 Verbatim Copying
\layout Standard

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.
\layout Standard

You may also lend copies, under the same conditions stated above, and you
 may publicly display copies.
\layout Subsection*

3.
 Copying in Quantity
\layout Standard

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.
\layout Standard

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.
\layout Standard

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-accessib
le 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.
\layout Standard

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.
\layout Subsection*

4.
 Modifications
\layout Standard

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:
\layout Enumerate

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.
\layout Enumerate

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).
\layout Enumerate

State on the Title page the name of the publisher of the Modified Version,
 as the publisher.
\layout Enumerate

Preserve all the copyright notices of the Document.
\layout Enumerate

Add an appropriate copyright notice for your modifications adjacent to the
 other copyright notices.
\layout Enumerate

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.
\layout Enumerate

Preserve in that license notice the full lists of Invariant Sections and
 required Cover Texts given in the Document's license notice.
\layout Enumerate

Include an unaltered copy of this License.
\layout Enumerate

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.
\layout Enumerate

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.
\layout Enumerate

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.
\layout Enumerate

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.
\layout Enumerate

Delete any section entitled "Endorsements." Such a section may not be included
 in the Modified Version.
\layout Enumerate

Do not retitle any existing section as "Endorsements" or to conflict in
 title with any Invariant Section.
\layout Standard

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.
\layout Standard

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.
\layout 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.
\layout Standard

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 endorseme
nt of any Modified Version.
\layout Subsection*

5.
 Combining Documents
\layout Standard

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.
\layout Standard

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.
\layout Standard

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."
\layout Subsection*

6.
 Collections of Documents
\layout Standard

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.
\layout Standard

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.
\layout Subsection*

7.
 Aggregation with Independent Works
\layout Standard

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.
\layout Standard

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.
\layout Subsection*

8.
 Translation
\layout Standard

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.
\layout Subsection*

9.
 Termination
\layout Standard

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.
\layout Subsection*

10.
 Future Revisions of This License
\layout Standard

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.
\layout Standard

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 Foundatio
n.
 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.
\layout Subsection*

Addendum: How to use this License for your documents
\layout Standard

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:
\layout Quote
\align center 
Copyright © [year] [your name]
\layout Quote

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 [
\emph on 
list their titles
\emph default 
], with the Front-Cover Texts being [
\emph on 
list
\emph default 
], and with the Back-Cover Texts being [
\emph on 
list
\emph default 
].
 A copy of the license is included in the section entitled "GNU Free Documentati
on License."
\layout Standard

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 [
\emph on 
list
\emph default 
]"; likewise for Back-Cover Texts.
\layout Standard

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.
