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

-0. PREAMBLE
9
-
10
-The purpose of this License is to make a manual, textbook, or other functional and useful document "free" in the sense of freedom: to assure everyone the effective freedom to copy and redistribute it, with or without modifying it, either commercially or noncommercially. Secondarily, this License preserves for the author and publisher a way to get credit for their work, while not being considered responsible for modifications made by others.
11
-
12
-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.
13
-
14
-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. 
15

16
-1. APPLICABILITY AND DEFINITIONS
17
-
18
-This License applies to any manual or other work, in any medium, that contains a notice placed by the copyright holder saying it can be distributed under the terms of this License. Such a notice grants a world-wide, royalty-free license, unlimited in duration, to use that work under the conditions stated herein. The "Document", below, refers to any such manual or work. Any member of the public is a licensee, and is addressed as "you". You accept the license if you copy, modify or distribute the work in a way requiring permission under copyright law.
19
-
20
-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.
21
-
22
-A "Secondary Section" is a named appendix or a front-matter section of the Document that deals exclusively with the relationship of the publishers or authors of the Document to the Document's overall subject (or to related matters) and contains nothing that could fall directly within that overall subject. (Thus, if the Document is in part a textbook of mathematics, a Secondary Section may not explain any mathematics.) The relationship could be a matter of historical connection with the subject or with related matters, or of legal, commercial, philosophical, ethical or political position regarding them.
23
-
24
-The "Invariant Sections" are certain Secondary Sections whose titles are designated, as being those of Invariant Sections, in the notice that says that the Document is released under this License. If a section does not fit the above definition of Secondary then it is not allowed to be designated as Invariant. The Document may contain zero Invariant Sections. If the Document does not identify any Invariant Sections then there are none.
25
-
26
-The "Cover Texts" are certain short passages of text that are listed, as Front-Cover Texts or Back-Cover Texts, in the notice that says that the Document is released under this License. A Front-Cover Text may be at most 5 words, and a Back-Cover Text may be at most 25 words.
27
-
28
-A "Transparent" copy of the Document means a machine-readable copy, represented in a format whose specification is available to the general public, that is suitable for revising the document straightforwardly with generic text editors or (for images composed of pixels) generic paint programs or (for drawings) some widely available drawing editor, and that is suitable for input to text formatters or for automatic translation to a variety of formats suitable for input to text formatters. A copy made in an otherwise Transparent file format whose markup, or absence of markup, has been arranged to thwart or discourage subsequent modification by readers is not Transparent. An image format is not Transparent if used for any substantial amount of text. A copy that is not "Transparent" is called "Opaque".
29
-
30
-Examples of suitable formats for Transparent copies include plain ASCII without markup, Texinfo input format, LaTeX input format, SGML or XML using a publicly available DTD, and standard-conforming simple HTML, PostScript or PDF designed for human modification. Examples of transparent image formats include PNG, XCF and JPG. Opaque formats include proprietary formats that can be read and edited only by proprietary word processors, SGML or XML for which the DTD and/or processing tools are not generally available, and the machine-generated HTML, PostScript or PDF produced by some word processors for output purposes only.
31
-
32
-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.
33
-
34
-The "publisher" means any person or entity that distributes copies of the Document to the public.
35
-
36
-A section "Entitled XYZ" means a named subunit of the Document whose title either is precisely XYZ or contains XYZ in parentheses following text that translates XYZ in another language. (Here XYZ stands for a specific section name mentioned below, such as "Acknowledgements", "Dedications", "Endorsements", or "History".) To "Preserve the Title" of such a section when you modify the Document means that it remains a section "Entitled XYZ" according to this definition.
37
-
38
-The Document may include Warranty Disclaimers next to the notice which states that this License applies to the Document. These Warranty Disclaimers are considered to be included by reference in this License, but only as regards disclaiming warranties: any other implication that these Warranty Disclaimers may have is void and has no effect on the meaning of this License.
39
-
40
-2. VERBATIM COPYING
41
-
42
-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.
43
-
44
-You may also lend copies, under the same conditions stated above, and you may publicly display copies. 
45
-
46
-3. COPYING IN QUANTITY
47
-
48
-If you publish printed copies (or copies in media that commonly have printed covers) of the Document, numbering more than 100, and the Document's license notice requires Cover Texts, you must enclose the copies in covers that carry, clearly and legibly, all these Cover Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on the back cover. Both covers must also clearly and legibly identify you as the publisher of these copies. The front cover must present the full title with all words of the title equally prominent and visible. You may add other material on the covers in addition. Copying with changes limited to the covers, as long as they preserve the title of the Document and satisfy these conditions, can be treated as verbatim copying in other respects.
49
-
50
-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.
51
-
52
-If you publish or distribute Opaque copies of the Document numbering more than 100, you must either include a machine-readable Transparent copy along with each Opaque copy, or state in or with each Opaque copy a computer-network location from which the general network-using public has access to download using public-standard network protocols a complete Transparent copy of the Document, free of added material. If you use the latter option, you must take reasonably prudent steps, when you begin distribution of Opaque copies in quantity, to ensure that this Transparent copy will remain thus accessible at the stated location until at least one year after the last time you distribute an Opaque copy (directly or through your agents or retailers) of that edition to the public.
53
-
54
-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. 
55
-
56
-4. MODIFICATIONS
57
-
58
-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:
59
-
60
-     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. 
61
-     B. List on the Title Page, as authors, one or more persons or entities responsible for authorship of the modifications in the Modified Version, together with at least five of the principal authors of the Document (all of its principal authors, if it has fewer than five), unless they release you from this requirement. 
62
-     C. State on the Title page the name of the publisher of the Modified Version, as the publisher. 
63
-     D. Preserve all the copyright notices of the Document. 
64
-     E. Add an appropriate copyright notice for your modifications adjacent to the other copyright notices. 
65
-     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. 
66
-     G. Preserve in that license notice the full lists of Invariant Sections and required Cover Texts given in the Document's license notice. H. Include an unaltered copy of this License. 
67
-     I. Preserve the section Entitled "History", Preserve its Title, and add to it an item stating at least the title, year, new authors, and publisher of the Modified Version as given on the Title Page. If there is no section Entitled "History" in the Document, create one stating the title, year, authors, and publisher of the Document as given on its Title Page, then add an item describing the Modified Version as stated in the previous sentence. 
68
-     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. 
69
-     K. For any section Entitled "Acknowledgements" or "Dedications", Preserve the Title of the section, and preserve in the section all the substance and tone of each of the contributor acknowledgements and/or dedications given therein. 
70
-     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. 
71
-     M. Delete any section Entitled "Endorsements". Such a section may not be included in the Modified Version. 
72
-     N. Do not retitle any existing section to be Entitled "Endorsements" or to conflict in title with any Invariant Section. 
73
-     O. Preserve any Warranty Disclaimers.
74
-
75
-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.
76
-
77
-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.
78
-
79
-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.
80
-
81
-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. 
82
-
83
-5. COMBINING DOCUMENTS
84
-
85
-You may combine the Document with other documents released under this License, under the terms defined in section 4 above for modified versions, provided that you include in the combination all of the Invariant Sections of all of the original documents, unmodified, and list them all as Invariant Sections of your combined work in its license notice, and that you preserve all their Warranty Disclaimers.
86
-
87
-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.
88
-
89
-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". 
90
-
91
-6. COLLECTIONS OF DOCUMENTS
92
-
93
-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.
94
-
95
-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. 
96
-
97
-7. AGGREGATION WITH INDEPENDENT WORKS
98
-
99
-A compilation of the Document or its derivatives with other separate and independent documents or works, in or on a volume of a storage or distribution medium, is called an "aggregate" if the copyright resulting from the compilation is not used to limit the legal rights of the compilation's users beyond what the individual works permit. When the Document is included in an aggregate, this License does not apply to the other works in the aggregate which are not themselves derivative works of the Document.
100
-
101
-If the Cover Text requirement of section 3 is applicable to these copies of the Document, then if the Document is less than one half of the entire aggregate, the Document's Cover Texts may be placed on covers that bracket the Document within the aggregate, or the electronic equivalent of covers if the Document is in electronic form. Otherwise they must appear on printed covers that bracket the whole aggregate. 
102
-
103
-8. TRANSLATION
104
-
105
-Translation is considered a kind of modification, so you may distribute translations of the Document under the terms of section 4. Replacing Invariant Sections with translations requires special permission from their copyright holders, but you may include translations of some or all Invariant Sections in addition to the original versions of these Invariant Sections. You may include a translation of this License, and all the license notices in the Document, and any Warranty Disclaimers, provided that you also include the original English version of this License and the original versions of those notices and disclaimers. In case of a disagreement between the translation and the original version of this License or a notice or disclaimer, the original version will prevail.
106
-
107
-If a section in the Document is Entitled "Acknowledgements", "Dedications", or "History", the requirement (section 4) to Preserve its Title (section 1) will typically require changing the actual title. 
108
-
109
-9. TERMINATION
110
-
111
-You may not copy, modify, sublicense, or distribute the Document except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, or distribute it is void, and will automatically terminate your rights under this License.
112
-
113
-However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation.
114
-
115
-Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice.
116
-
117
-Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, receipt of a copy of some or all of the same material does not give you any rights to use it. 
118
-
119
-10. FUTURE REVISIONS OF THIS LICENSE
120
-
121
-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/.
122
-
123
-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. If the Document specifies that a proxy can decide which future versions of this License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Document.
124

125
-11. RELICENSING
126
-
127
-"Massive Multiauthor Collaboration Site" (or "MMC Site") means any World Wide Web server that publishes copyrightable works and also provides prominent facilities for anybody to edit those works. A public wiki that anybody can edit is an example of such a server. A "Massive Multiauthor Collaboration" (or "MMC") contained in the site means any set of copyrightable works thus published on the MMC site.
128
-
129
-"CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0 license published by Creative Commons Corporation, a not-for-profit corporation with a principal place of business in San Francisco, California, as well as future copyleft versions of that license published by that same organization.
130
-
131
-"Incorporate" means to publish or republish a Document, in whole or in part, as part of another Document.
132
-
133
-An MMC is "eligible for relicensing" if it is licensed under this License, and if all works that were first published under this License somewhere other than this MMC, and subsequently incorporated in whole or in part into the MMC, (1) had no cover texts or invariant sections, and (2) were thus incorporated prior to November 1, 2008.
134
-
135
-The operator of an MMC Site may republish an MMC contained in the site under CC-BY-SA on the same site at any time before August 1, 2009, provided the MMC is eligible for relicensing. 
136
-
137
-ADDENDUM: How to use this License for your documents
138
-
139
-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:
140
-
141
- 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 1.3 or any later version published by the Free Software Foundation; with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts. A copy of the license is included in the section entitled "GNU Free Documentation License".
142
-
143
-If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts, replace the "with...Texts." line with this:
144
-
145
- with the Invariant Sections being LIST THEIR TITLES, with the Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST.
146
-
147
-If you have Invariant Sections without Cover Texts, or some other combination of the three, merge those two alternatives to suit the situation.
148
-
149
-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.

45
+<h4><a name="section1"></a>1. APPLICABILITY AND DEFINITIONS</h4>
46
+
47
+<p>This License applies to any manual or other work, in any medium, that
48
+contains a notice placed by the copyright holder saying it can be
49
+distributed under the terms of this License.  Such a notice grants a
50
+world-wide, royalty-free license, unlimited in duration, to use that
51
+work under the conditions stated herein.  The &quot;Document&quot;, below,
52
+refers to any such manual or work.  Any member of the public is a
53
+licensee, and is addressed as &quot;you&quot;.  You accept the license if you
54
+copy, modify or distribute the work in a way requiring permission
55
+under copyright law.</p>
56
+
57
+<p>A &quot;Modified Version&quot; of the Document means any work containing the
58
+Document or a portion of it, either copied verbatim, or with
59
+modifications and/or translated into another language.</p>
60
+
61
+<p>A &quot;Secondary Section&quot; is a named appendix or a front-matter section of
62
+the Document that deals exclusively with the relationship of the
63
+publishers or authors of the Document to the Document's overall
64
+subject (or to related matters) and contains nothing that could fall
65
+directly within that overall subject.  (Thus, if the Document is in
66
+part a textbook of mathematics, a Secondary Section may not explain
67
+any mathematics.)  The relationship could be a matter of historical
68
+connection with the subject or with related matters, or of legal,
69
+commercial, philosophical, ethical or political position regarding
70
+them.</p>
71
+
72
+<p>The &quot;Invariant Sections&quot; are certain Secondary Sections whose titles
73
+are designated, as being those of Invariant Sections, in the notice
74
+that says that the Document is released under this License.  If a
75
+section does not fit the above definition of Secondary then it is not
76
+allowed to be designated as Invariant.  The Document may contain zero
77
+Invariant Sections.  If the Document does not identify any Invariant
78
+Sections then there are none.</p>
79
+
80
+<p>The &quot;Cover Texts&quot; are certain short passages of text that are listed,
81
+as Front-Cover Texts or Back-Cover Texts, in the notice that says that
82
+the Document is released under this License.  A Front-Cover Text may
83
+be at most 5 words, and a Back-Cover Text may be at most 25 words.</p>
84
+
85
+<p>A &quot;Transparent&quot; copy of the Document means a machine-readable copy,
86
+represented in a format whose specification is available to the
87
+general public, that is suitable for revising the document
88
+straightforwardly with generic text editors or (for images composed of
89
+pixels) generic paint programs or (for drawings) some widely available
90
+drawing editor, and that is suitable for input to text formatters or
91
+for automatic translation to a variety of formats suitable for input
92
+to text formatters.  A copy made in an otherwise Transparent file
93
+format whose markup, or absence of markup, has been arranged to thwart

+or discourage subsequent modification by readers is not Transparent.
95
+An image format is not Transparent if used for any substantial amount
96
+of text.  A copy that is not &quot;Transparent&quot; is called &quot;Opaque&quot;.</p>
97
+
98
+<p>Examples of suitable formats for Transparent copies include plain
99
+ASCII without markup, Texinfo input format, LaTeX input format, SGML
100
+or XML using a publicly available DTD, and standard-conforming simple
101
+HTML, PostScript or PDF designed for human modification.  Examples of
102
+transparent image formats include PNG, XCF and JPG.  Opaque formats
103
+include proprietary formats that can be read and edited only by
104
+proprietary word processors, SGML or XML for which the DTD and/or
105
+processing tools are not generally available, and the
106
+machine-generated HTML, PostScript or PDF produced by some word
107
+processors for output purposes only.</p>
108
+
109
+<p>The &quot;Title Page&quot; means, for a printed book, the title page itself,
110
+plus such following pages as are needed to hold, legibly, the material
111
+this License requires to appear in the title page.  For works in
112
+formats which do not have any title page as such, &quot;Title Page&quot; means
113
+the text near the most prominent appearance of the work's title,
114
+preceding the beginning of the body of the text.</p>
115
+
116
+<p>The &quot;publisher&quot; means any person or entity that distributes copies of
117
+the Document to the public.</p>
118
+
119
+<p>A section &quot;Entitled XYZ&quot; means a named subunit of the Document whose
120
+title either is precisely XYZ or contains XYZ in parentheses following
121
+text that translates XYZ in another language.  (Here XYZ stands for a
122
+specific section name mentioned below, such as &quot;Acknowledgements&quot;,
123
+&quot;Dedications&quot;, &quot;Endorsements&quot;, or &quot;History&quot;.)  To &quot;Preserve the Title&quot;
124
+of such a section when you modify the Document means that it remains a
125
+section &quot;Entitled XYZ&quot; according to this definition.</p>
126
+
127
+<p>The Document may include Warranty Disclaimers next to the notice which
128
+states that this License applies to the Document.  These Warranty
129
+Disclaimers are considered to be included by reference in this
130
+License, but only as regards disclaiming warranties: any other
131
+implication that these Warranty Disclaimers may have is void and has
132
+no effect on the meaning of this License.</p>
133
+
134
+<h4><a name="section2"></a>2. VERBATIM COPYING</h4>
135
+
136
+<p>You may copy and distribute the Document in any medium, either
137
+commercially or noncommercially, provided that this License, the
138
+copyright notices, and the license notice saying this License applies
139
+to the Document are reproduced in all copies, and that you add no
140
+other conditions whatsoever to those of this License.  You may not use
141
+technical measures to obstruct or control the reading or further
142
+copying of the copies you make or distribute.  However, you may accept
143
+compensation in exchange for copies.  If you distribute a large enough
144
+number of copies you must also follow the conditions in section 3.</p>
145
+
146
+<p>You may also lend copies, under the same conditions stated above, and
147
+you may publicly display copies.</p>
148
+
149
+<h4><a name="section3"></a>3. COPYING IN QUANTITY</h4>
150
+
151
+<p>If you publish printed copies (or copies in media that commonly have
152
+printed covers) of the Document, numbering more than 100, and the
153
+Document's license notice requires Cover Texts, you must enclose the
154
+copies in covers that carry, clearly and legibly, all these Cover
155
+Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
156
+the back cover.  Both covers must also clearly and legibly identify
157
+you as the publisher of these copies.  The front cover must present
158
+the full title with all words of the title equally prominent and
159
+visible.  You may add other material on the covers in addition.
160
+Copying with changes limited to the covers, as long as they preserve
161
+the title of the Document and satisfy these conditions, can be treated
162
+as verbatim copying in other respects.</p>
163
+
164
+<p>If the required texts for either cover are too voluminous to fit
165
+legibly, you should put the first ones listed (as many as fit
166
+reasonably) on the actual cover, and continue the rest onto adjacent
167
+pages.</p>
168
+
169
+<p>If you publish or distribute Opaque copies of the Document numbering
170
+more than 100, you must either include a machine-readable Transparent
171
+copy along with each Opaque copy, or state in or with each Opaque copy
172
+a computer-network location from which the general network-using
173
+public has access to download using public-standard network protocols
174
+a complete Transparent copy of the Document, free of added material.
175
+If you use the latter option, you must take reasonably prudent steps,
176
+when you begin distribution of Opaque copies in quantity, to ensure
177
+that this Transparent copy will remain thus accessible at the stated
178
+location until at least one year after the last time you distribute an
179
+Opaque copy (directly or through your agents or retailers) of that
180
+edition to the public.</p>
181
+
182
+<p>It is requested, but not required, that you contact the authors of the
183
+Document well before redistributing any large number of copies, to
184
+give them a chance to provide you with an updated version of the
185
+Document.</p>
186
+
187
+<h4><a name="section4"></a>4. MODIFICATIONS</h4>
188
+
189
+<p>You may copy and distribute a Modified Version of the Document under
190
+the conditions of sections 2 and 3 above, provided that you release
191
+the Modified Version under precisely this License, with the Modified
192
+Version filling the role of the Document, thus licensing distribution
193
+and modification of the Modified Version to whoever possesses a copy
194
+of it.  In addition, you must do these things in the Modified Version:</p>
195
+
196
+<ul>
197
+
198
+
199
+<li>A. Use in the Title Page (and on the covers, if any) a title distinct
200
+   from that of the Document, and from those of previous versions
201
+   (which should, if there were any, be listed in the History section
202
+   of the Document).  You may use the same title as a previous version
203
+   if the original publisher of that version gives permission.
204
+</li>
205
+
206
+<li>B. List on the Title Page, as authors, one or more persons or entities
207
+   responsible for authorship of the modifications in the Modified
208
+   Version, together with at least five of the principal authors of the
209
+   Document (all of its principal authors, if it has fewer than five),
210
+   unless they release you from this requirement.
211
+</li>
212
+
213
+<li>C. State on the Title page the name of the publisher of the
214
+   Modified Version, as the publisher.
215
+</li>
216
+
217
+<li>D. Preserve all the copyright notices of the Document.
218
+</li>
219
+
220
+<li>E. Add an appropriate copyright notice for your modifications
221
+   adjacent to the other copyright notices.
222
+</li>
223
+
224
+<li>F. Include, immediately after the copyright notices, a license notice
225
+   giving the public permission to use the Modified Version under the
226
+   terms of this License, in the form shown in the Addendum below.
227
+</li>
228
+
229
+<li>G. Preserve in that license notice the full lists of Invariant Sections
230
+   and required Cover Texts given in the Document's license notice.
231
+</li>
232
+
233
+<li>H. Include an unaltered copy of this License.
234
+</li>
235
+
236
+<li>I. Preserve the section Entitled &quot;History&quot;, Preserve its Title, and add
237
+   to it an item stating at least the title, year, new authors, and
238
+   publisher of the Modified Version as given on the Title Page.  If
239
+   there is no section Entitled &quot;History&quot; in the Document, create one
240
+   stating the title, year, authors, and publisher of the Document as
241
+   given on its Title Page, then add an item describing the Modified
242
+   Version as stated in the previous sentence.
243
+</li>
244
+
245
+<li>J. Preserve the network location, if any, given in the Document for
246
+   public access to a Transparent copy of the Document, and likewise
247
+   the network locations given in the Document for previous versions
248
+   it was based on.  These may be placed in the &quot;History&quot; section.
249
+   You may omit a network location for a work that was published at
250
+   least four years before the Document itself, or if the original
251
+   publisher of the version it refers to gives permission.
252
+</li>
253
+
254
+<li>K. For any section Entitled &quot;Acknowledgements&quot; or &quot;Dedications&quot;,
255
+   Preserve the Title of the section, and preserve in the section all
256
+   the substance and tone of each of the contributor acknowledgements
257
+   and/or dedications given therein.
258
+</li>
259
+
260
+<li>L. Preserve all the Invariant Sections of the Document,
261
+   unaltered in their text and in their titles.  Section numbers
262
+   or the equivalent are not considered part of the section titles.
263
+</li>
264
+
265
+<li>M. Delete any section Entitled &quot;Endorsements&quot;.  Such a section
266
+   may not be included in the Modified Version.
267
+</li>
268
+
269
+<li>N. Do not retitle any existing section to be Entitled &quot;Endorsements&quot;
270
+   or to conflict in title with any Invariant Section.
271
+</li>
272
+
273
+<li>O. Preserve any Warranty Disclaimers.</li>
274
+
275
+</ul>
276
+
277
+<p>If the Modified Version includes new front-matter sections or
278
+appendices that qualify as Secondary Sections and contain no material
279
+copied from the Document, you may at your option designate some or all
280
+of these sections as invariant.  To do this, add their titles to the
281
+list of Invariant Sections in the Modified Version's license notice.
282
+These titles must be distinct from any other section titles.</p>
283
+
284
+<p>You may add a section Entitled &quot;Endorsements&quot;, provided it contains
285
+nothing but endorsements of your Modified Version by various
286
+parties&mdash;for example, statements of peer review or that the text has
287
+been approved by an organization as the authoritative definition of a
288
+standard.</p>
289
+
290
+<p>You may add a passage of up to five words as a Front-Cover Text, and a
291
+passage of up to 25 words as a Back-Cover Text, to the end of the list
292
+of Cover Texts in the Modified Version.  Only one passage of
293
+Front-Cover Text and one of Back-Cover Text may be added by (or
294
+through arrangements made by) any one entity.  If the Document already
295
+includes a cover text for the same cover, previously added by you or
296
+by arrangement made by the same entity you are acting on behalf of,
297
+you may not add another; but you may replace the old one, on explicit
298
+permission from the previous publisher that added the old one.</p>
299
+
300
+<p>The author(s) and publisher(s) of the Document do not by this License
301
+give permission to use their names for publicity for or to assert or
302
+imply endorsement of any Modified Version.</p>
303
+
304
+<h4><a name="section5"></a>5. COMBINING DOCUMENTS</h4>
305
+
306
+<p>You may combine the Document with other documents released under this
307
+License, under the terms defined in section 4 above for modified
308
+versions, provided that you include in the combination all of the
309
+Invariant Sections of all of the original documents, unmodified, and
310
+list them all as Invariant Sections of your combined work in its
311
+license notice, and that you preserve all their Warranty Disclaimers.</p>
312
+
313
+<p>The combined work need only contain one copy of this License, and
314
+multiple identical Invariant Sections may be replaced with a single
315
+copy.  If there are multiple Invariant Sections with the same name but
316
+different contents, make the title of each such section unique by
317
+adding at the end of it, in parentheses, the name of the original
318
+author or publisher of that section if known, or else a unique number.
319
+Make the same adjustment to the section titles in the list of
320
+Invariant Sections in the license notice of the combined work.</p>
321
+
322
+<p>In the combination, you must combine any sections Entitled &quot;History&quot;
323
+in the various original documents, forming one section Entitled
324
+&quot;History&quot;; likewise combine any sections Entitled &quot;Acknowledgements&quot;,
325
+and any sections Entitled &quot;Dedications&quot;.  You must delete all sections
326
+Entitled &quot;Endorsements&quot;.</p>
327
+
328
+<h4><a name="section6"></a>6. COLLECTIONS OF DOCUMENTS</h4>
329
+
330
+<p>You may make a collection consisting of the Document and other
331
+documents released under this License, and replace the individual
332
+copies of this License in the various documents with a single copy
333
+that is included in the collection, provided that you follow the rules
334
+of this License for verbatim copying of each of the documents in all
335
+other respects.</p>
336
+
337
+<p>You may extract a single document from such a collection, and
338
+distribute it individually under this License, provided you insert a
339
+copy of this License into the extracted document, and follow this
340
+License in all other respects regarding verbatim copying of that
341
+document.</p>
342
+
343
+<h4><a name="section7"></a>7. AGGREGATION WITH INDEPENDENT WORKS</h4>
344
+
345
+<p>A compilation of the Document or its derivatives with other separate
346
+and independent documents or works, in or on a volume of a storage or
347
+distribution medium, is called an &quot;aggregate&quot; if the copyright
348
+resulting from the compilation is not used to limit the legal rights
349
+of the compilation's users beyond what the individual works permit.
350
+When the Document is included in an aggregate, this License does not
351
+apply to the other works in the aggregate which are not themselves
352
+derivative works of the Document.</p>
353
+
354
+<p>If the Cover Text requirement of section 3 is applicable to these
355
+copies of the Document, then if the Document is less than one half of
356
+the entire aggregate, the Document's Cover Texts may be placed on
357
+covers that bracket the Document within the aggregate, or the
358
+electronic equivalent of covers if the Document is in electronic form.
359
+Otherwise they must appear on printed covers that bracket the whole
360
+aggregate.</p>
361
+
362
+<h4><a name="section8"></a>8. TRANSLATION</h4>
363
+
364
+<p>Translation is considered a kind of modification, so you may
365
+distribute translations of the Document under the terms of section 4.
366
+Replacing Invariant Sections with translations requires special
367
+permission from their copyright holders, but you may include
368
+translations of some or all Invariant Sections in addition to the
369
+original versions of these Invariant Sections.  You may include a
370
+translation of this License, and all the license notices in the
371
+Document, and any Warranty Disclaimers, provided that you also include
372
+the original English version of this License and the original versions
373
+of those notices and disclaimers.  In case of a disagreement between
374
+the translation and the original version of this License or a notice
375
+or disclaimer, the original version will prevail.</p>
376
+
377
+<p>If a section in the Document is Entitled &quot;Acknowledgements&quot;,
378
+&quot;Dedications&quot;, or &quot;History&quot;, the requirement (section 4) to Preserve
379
+its Title (section 1) will typically require changing the actual
380
+title.</p>
381
+
382
+<h4><a name="section9"></a>9. TERMINATION</h4>
383
+
384
+<p>You may not copy, modify, sublicense, or distribute the Document
385
+except as expressly provided under this License.  Any attempt
386
+otherwise to copy, modify, sublicense, or distribute it is void, and
387
+will automatically terminate your rights under this License.</p>
388
+
389
+<p>However, if you cease all violation of this License, then your license
390
+from a particular copyright holder is reinstated (a) provisionally,
391
+unless and until the copyright holder explicitly and finally
392
+terminates your license, and (b) permanently, if the copyright holder
393
+fails to notify you of the violation by some reasonable means prior to
394
+60 days after the cessation.</p>
395
+
396
+<p>Moreover, your license from a particular copyright holder is
397
+reinstated permanently if the copyright holder notifies you of the
398
+violation by some reasonable means, this is the first time you have
399
+received notice of violation of this License (for any work) from that
400
+copyright holder, and you cure the violation prior to 30 days after
401
+your receipt of the notice.</p>
402
+
403
+<p>Termination of your rights under this section does not terminate the
404
+licenses of parties who have received copies or rights from you under
405
+this License.  If your rights have been terminated and not permanently
406
+reinstated, receipt of a copy of some or all of the same material does
407
+not give you any rights to use it.</p>
408
+
409
+<h4><a name="section10"></a>10. FUTURE REVISIONS OF THIS LICENSE</h4>
410
+
411
+<p>The Free Software Foundation may publish new, revised versions of the
412
+GNU Free Documentation License from time to time.  Such new versions
413
+will be similar in spirit to the present version, but may differ in
414
+detail to address new problems or concerns.  See
415
+<a href="https://www.gnu.org/licenses/">https://www.gnu.org/licenses/</a>.</p>
416
+
417
+<p>Each version of the License is given a distinguishing version number.
418
+If the Document specifies that a particular numbered version of this
419
+License &quot;or any later version&quot; applies to it, you have the option of
420
+following the terms and conditions either of that specified version or
421
+of any later version that has been published (not as a draft) by the
422
+Free Software Foundation.  If the Document does not specify a version
423
+number of this License, you may choose any version ever published (not
424
+as a draft) by the Free Software Foundation.  If the Document
425
+specifies that a proxy can decide which future versions of this
426
+License can be used, that proxy's public statement of acceptance of a
427
+version permanently authorizes you to choose that version for the
428
+Document.</p>
429
+
430
+<h4><a name="section11"></a>11. RELICENSING</h4>
431
+
432
+<p>&quot;Massive Multiauthor Collaboration Site&quot; (or &quot;MMC Site&quot;) means any
433
+World Wide Web server that publishes copyrightable works and also
434
+provides prominent facilities for anybody to edit those works.  A
435
+public wiki that anybody can edit is an example of such a server.  A
436
+&quot;Massive Multiauthor Collaboration&quot; (or &quot;MMC&quot;) contained in the site
437
+means any set of copyrightable works thus published on the MMC site.</p>
438
+
439
+<p>&quot;CC-BY-SA&quot; means the Creative Commons Attribution-Share Alike 3.0 
440
+license published by Creative Commons Corporation, a not-for-profit 
441
+corporation with a principal place of business in San Francisco, 
442
+California, as well as future copyleft versions of that license 
443
+published by that same organization.</p>
444
+
445
+<p>&quot;Incorporate&quot; means to publish or republish a Document, in whole or in 
446
+part, as part of another Document.</p>
447
+
448
+<p>An MMC is &quot;eligible for relicensing&quot; if it is licensed under this 
449
+License, and if all works that were first published under this License 
450
+somewhere other than this MMC, and subsequently incorporated in whole or 
451
+in part into the MMC, (1) had no cover texts or invariant sections, and 
452
+(2) were thus incorporated prior to November 1, 2008.</p>
453
+
454
+<p>The operator of an MMC Site may republish an MMC contained in the site
455
+under CC-BY-SA on the same site at any time before August 1, 2009,
456
+provided the MMC is eligible for relicensing.</p>
457

458
+<h3><a name="addendum"></a>ADDENDUM: How to use this License for your documents</h3>
459
+
460
+<p>To use this License in a document you have written, include a copy of
461
+the License in the document and put the following copyright and
462
+license notices just after the title page:</p>
463
+
464
+<pre>    Copyright (C)  YEAR  YOUR NAME.
465
+    Permission is granted to copy, distribute and/or modify this document
466
+    under the terms of the GNU Free Documentation License, Version 1.3
467
+    or any later version published by the Free Software Foundation;
468
+    with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts.
469
+    A copy of the license is included in the section entitled &quot;GNU
470
+    Free Documentation License&quot;.
471
+</pre>
472
+
473
+<p>If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
474
+replace the &quot;with &hellip; Texts.&quot; line with this:</p>
475
+
476
+<pre>    with the Invariant Sections being LIST THEIR TITLES, with the
477
+    Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST.
478
+</pre>
479
+
480
+<p>If you have Invariant Sections without Cover Texts, or some other
481
+combination of the three, merge those two alternatives to suit the
482
+situation.</p>
483
+
484
+<p>If your document contains nontrivial examples of program code, we
485
+recommend releasing these examples in parallel under your choice of
486
+free software license, such as the GNU General Public License,
487
+to permit their use in free software.

8
+ Everyone is permitted to copy and distribute verbatim copies
9
+ of this license document, but changing it is not allowed.
10
+
11
+0. PREAMBLE
12
+
13
+The purpose of this License is to make a manual, textbook, or other
14
+functional and useful document "free" in the sense of freedom: to
15
+assure everyone the effective freedom to copy and redistribute it,
16
+with or without modifying it, either commercially or noncommercially.
17
+Secondarily, this License preserves for the author and publisher a way
18
+to get credit for their work, while not being considered responsible
19
+for modifications made by others.
20
+
21
+This License is a kind of "copyleft", which means that derivative
22
+works of the document must themselves be free in the same sense.  It
23
+complements the GNU General Public License, which is a copyleft
24
+license designed for free software.
25
+
26
+We have designed this License in order to use it for manuals for free
27
+software, because free software needs free documentation: a free
28
+program should come with manuals providing the same freedoms that the
29
+software does.  But this License is not limited to software manuals;
30
+it can be used for any textual work, regardless of subject matter or
31
+whether it is published as a printed book.  We recommend this License
32
+principally for works whose purpose is instruction or reference.
33
+
34
+
35
+1. APPLICABILITY AND DEFINITIONS
36
+
37
+This License applies to any manual or other work, in any medium, that
38
+contains a notice placed by the copyright holder saying it can be
39
+distributed under the terms of this License.  Such a notice grants a
40
+world-wide, royalty-free license, unlimited in duration, to use that
41
+work under the conditions stated herein.  The "Document", below,
42
+refers to any such manual or work.  Any member of the public is a
43
+licensee, and is addressed as "you".  You accept the license if you
44
+copy, modify or distribute the work in a way requiring permission
45
+under copyright law.
46
+
47
+A "Modified Version" of the Document means any work containing the
48
+Document or a portion of it, either copied verbatim, or with
49
+modifications and/or translated into another language.
50
+
51
+A "Secondary Section" is a named appendix or a front-matter section of
52
+the Document that deals exclusively with the relationship of the
53
+publishers or authors of the Document to the Document's overall
54
+subject (or to related matters) and contains nothing that could fall
55
+directly within that overall subject.  (Thus, if the Document is in
56
+part a textbook of mathematics, a Secondary Section may not explain
57
+any mathematics.)  The relationship could be a matter of historical
58
+connection with the subject or with related matters, or of legal,
59
+commercial, philosophical, ethical or political position regarding
60
+them.
61
+
62
+The "Invariant Sections" are certain Secondary Sections whose titles
63
+are designated, as being those of Invariant Sections, in the notice
64
+that says that the Document is released under this License.  If a
65
+section does not fit the above definition of Secondary then it is not
66
+allowed to be designated as Invariant.  The Document may contain zero
67
+Invariant Sections.  If the Document does not identify any Invariant
68
+Sections then there are none.
69
+
70
+The "Cover Texts" are certain short passages of text that are listed,
71
+as Front-Cover Texts or Back-Cover Texts, in the notice that says that
72
+the Document is released under this License.  A Front-Cover Text may
73
+be at most 5 words, and a Back-Cover Text may be at most 25 words.
74
+
75
+A "Transparent" copy of the Document means a machine-readable copy,
76
+represented in a format whose specification is available to the
77
+general public, that is suitable for revising the document
78
+straightforwardly with generic text editors or (for images composed of
79
+pixels) generic paint programs or (for drawings) some widely available
80
+drawing editor, and that is suitable for input to text formatters or
81
+for automatic translation to a variety of formats suitable for input
82
+to text formatters.  A copy made in an otherwise Transparent file
83
+format whose markup, or absence of markup, has been arranged to thwart
84
+or discourage subsequent modification by readers is not Transparent.
85
+An image format is not Transparent if used for any substantial amount
86
+of text.  A copy that is not "Transparent" is called "Opaque".
87
+
88
+Examples of suitable formats for Transparent copies include plain
89
+ASCII without markup, Texinfo input format, LaTeX input format, SGML
90
+or XML using a publicly available DTD, and standard-conforming simple
91
+HTML, PostScript or PDF designed for human modification.  Examples of
92
+transparent image formats include PNG, XCF and JPG.  Opaque formats
93
+include proprietary formats that can be read and edited only by
94
+proprietary word processors, SGML or XML for which the DTD and/or
95
+processing tools are not generally available, and the
96
+machine-generated HTML, PostScript or PDF produced by some word
97
+processors for output purposes only.
98
+
99
+The "Title Page" means, for a printed book, the title page itself,
100
+plus such following pages as are needed to hold, legibly, the material
101
+this License requires to appear in the title page.  For works in
102
+formats which do not have any title page as such, "Title Page" means
103
+the text near the most prominent appearance of the work's title,
104
+preceding the beginning of the body of the text.
105
+
106
+The "publisher" means any person or entity that distributes copies of
107
+the Document to the public.
108
+
109
+A section "Entitled XYZ" means a named subunit of the Document whose
110
+title either is precisely XYZ or contains XYZ in parentheses following
111
+text that translates XYZ in another language.  (Here XYZ stands for a
112
+specific section name mentioned below, such as "Acknowledgements",
113
+"Dedications", "Endorsements", or "History".)  To "Preserve the Title"
114
+of such a section when you modify the Document means that it remains a
115
+section "Entitled XYZ" according to this definition.
116
+
117
+The Document may include Warranty Disclaimers next to the notice which
118
+states that this License applies to the Document.  These Warranty
119
+Disclaimers are considered to be included by reference in this
120
+License, but only as regards disclaiming warranties: any other
121
+implication that these Warranty Disclaimers may have is void and has
122
+no effect on the meaning of this License.
123
+
124
+2. VERBATIM COPYING
125
+
126
+You may copy and distribute the Document in any medium, either
127
+commercially or noncommercially, provided that this License, the
128
+copyright notices, and the license notice saying this License applies
129
+to the Document are reproduced in all copies, and that you add no
130
+other conditions whatsoever to those of this License.  You may not use
131
+technical measures to obstruct or control the reading or further
132
+copying of the copies you make or distribute.  However, you may accept
133
+compensation in exchange for copies.  If you distribute a large enough
134
+number of copies you must also follow the conditions in section 3.
135
+
136
+You may also lend copies, under the same conditions stated above, and
137
+you may publicly display copies.
138
+
139
+
140
+3. COPYING IN QUANTITY
141
+
142
+If you publish printed copies (or copies in media that commonly have
143
+printed covers) of the Document, numbering more than 100, and the
144
+Document's license notice requires Cover Texts, you must enclose the
145
+copies in covers that carry, clearly and legibly, all these Cover
146
+Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
147
+the back cover.  Both covers must also clearly and legibly identify
148
+you as the publisher of these copies.  The front cover must present
149
+the full title with all words of the title equally prominent and
150
+visible.  You may add other material on the covers in addition.
151
+Copying with changes limited to the covers, as long as they preserve
152
+the title of the Document and satisfy these conditions, can be treated
153
+as verbatim copying in other respects.
154
+
155
+If the required texts for either cover are too voluminous to fit
156
+legibly, you should put the first ones listed (as many as fit
157
+reasonably) on the actual cover, and continue the rest onto adjacent
158
+pages.
159
+
160
+If you publish or distribute Opaque copies of the Document numbering
161
+more than 100, you must either include a machine-readable Transparent
162
+copy along with each Opaque copy, or state in or with each Opaque copy
163
+a computer-network location from which the general network-using
164
+public has access to download using public-standard network protocols
165
+a complete Transparent copy of the Document, free of added material.
166
+If you use the latter option, you must take reasonably prudent steps,
167
+when you begin distribution of Opaque copies in quantity, to ensure
168
+that this Transparent copy will remain thus accessible at the stated
169
+location until at least one year after the last time you distribute an
170
+Opaque copy (directly or through your agents or retailers) of that
171
+edition to the public.
172
+
173
+It is requested, but not required, that you contact the authors of the
174
+Document well before redistributing any large number of copies, to
175
+give them a chance to provide you with an updated version of the
176
+Document.
177
+
178
+
179
+4. MODIFICATIONS
180
+
181
+You may copy and distribute a Modified Version of the Document under
182
+the conditions of sections 2 and 3 above, provided that you release
183
+the Modified Version under precisely this License, with the Modified
184
+Version filling the role of the Document, thus licensing distribution
185
+and modification of the Modified Version to whoever possesses a copy
186
+of it.  In addition, you must do these things in the Modified Version:
187
+
188
+A. Use in the Title Page (and on the covers, if any) a title distinct
189
+   from that of the Document, and from those of previous versions
190
+   (which should, if there were any, be listed in the History section
191
+   of the Document).  You may use the same title as a previous version
192
+   if the original publisher of that version gives permission.
193
+B. List on the Title Page, as authors, one or more persons or entities
194
+   responsible for authorship of the modifications in the Modified
195
+   Version, together with at least five of the principal authors of the
196
+   Document (all of its principal authors, if it has fewer than five),
197
+   unless they release you from this requirement.
198
+C. State on the Title page the name of the publisher of the
199
+   Modified Version, as the publisher.
200
+D. Preserve all the copyright notices of the Document.
201
+E. Add an appropriate copyright notice for your modifications
202
+   adjacent to the other copyright notices.
203
+F. Include, immediately after the copyright notices, a license notice
204
+   giving the public permission to use the Modified Version under the
205
+   terms of this License, in the form shown in the Addendum below.
206
+G. Preserve in that license notice the full lists of Invariant Sections
207
+   and required Cover Texts given in the Document's license notice.
208
+H. Include an unaltered copy of this License.
209
+I. Preserve the section Entitled "History", Preserve its Title, and add
210
+   to it an item stating at least the title, year, new authors, and
211
+   publisher of the Modified Version as given on the Title Page.  If
212
+   there is no section Entitled "History" in the Document, create one
213
+   stating the title, year, authors, and publisher of the Document as
214
+   given on its Title Page, then add an item describing the Modified
215
+   Version as stated in the previous sentence.
216
+J. Preserve the network location, if any, given in the Document for
217
+   public access to a Transparent copy of the Document, and likewise
218
+   the network locations given in the Document for previous versions
219
+   it was based on.  These may be placed in the "History" section.
220
+   You may omit a network location for a work that was published at
221
+   least four years before the Document itself, or if the original
222
+   publisher of the version it refers to gives permission.
223
+K. For any section Entitled "Acknowledgements" or "Dedications",
224
+   Preserve the Title of the section, and preserve in the section all
225
+   the substance and tone of each of the contributor acknowledgements
226
+   and/or dedications given therein.
227
+L. Preserve all the Invariant Sections of the Document,
228
+   unaltered in their text and in their titles.  Section numbers
229
+   or the equivalent are not considered part of the section titles.
230
+M. Delete any section Entitled "Endorsements".  Such a section
231
+   may not be included in the Modified Version.
232
+N. Do not retitle any existing section to be Entitled "Endorsements"
233
+   or to conflict in title with any Invariant Section.
234
+O. Preserve any Warranty Disclaimers.
235
+
236
+If the Modified Version includes new front-matter sections or
237
+appendices that qualify as Secondary Sections and contain no material
238
+copied from the Document, you may at your option designate some or all
239
+of these sections as invariant.  To do this, add their titles to the
240
+list of Invariant Sections in the Modified Version's license notice.
241
+These titles must be distinct from any other section titles.
242
+
243
+You may add a section Entitled "Endorsements", provided it contains
244
+nothing but endorsements of your Modified Version by various
245
+parties--for example, statements of peer review or that the text has
246
+been approved by an organization as the authoritative definition of a
247
+standard.
248
+
249
+You may add a passage of up to five words as a Front-Cover Text, and a
250
+passage of up to 25 words as a Back-Cover Text, to the end of the list
251
+of Cover Texts in the Modified Version.  Only one passage of
252
+Front-Cover Text and one of Back-Cover Text may be added by (or
253
+through arrangements made by) any one entity.  If the Document already
254
+includes a cover text for the same cover, previously added by you or
255
+by arrangement made by the same entity you are acting on behalf of,
256
+you may not add another; but you may replace the old one, on explicit
257
+permission from the previous publisher that added the old one.
258
+
259
+The author(s) and publisher(s) of the Document do not by this License
260
+give permission to use their names for publicity for or to assert or
261
+imply endorsement of any Modified Version.
262
+
263
+
264
+5. COMBINING DOCUMENTS
265
+
266
+You may combine the Document with other documents released under this
267
+License, under the terms defined in section 4 above for modified
268
+versions, provided that you include in the combination all of the
269
+Invariant Sections of all of the original documents, unmodified, and
270
+list them all as Invariant Sections of your combined work in its
271
+license notice, and that you preserve all their Warranty Disclaimers.
272
+
273
+The combined work need only contain one copy of this License, and
274
+multiple identical Invariant Sections may be replaced with a single
275
+copy.  If there are multiple Invariant Sections with the same name but
276
+different contents, make the title of each such section unique by
277
+adding at the end of it, in parentheses, the name of the original
278
+author or publisher of that section if known, or else a unique number.
279
+Make the same adjustment to the section titles in the list of
280
+Invariant Sections in the license notice of the combined work.
281
+
282
+In the combination, you must combine any sections Entitled "History"
283
+in the various original documents, forming one section Entitled
284
+"History"; likewise combine any sections Entitled "Acknowledgements",
285
+and any sections Entitled "Dedications".  You must delete all sections
286
+Entitled "Endorsements".
287
+
288
+
289
+6. COLLECTIONS OF DOCUMENTS
290
+
291
+You may make a collection consisting of the Document and other
292
+documents released under this License, and replace the individual
293
+copies of this License in the various documents with a single copy
294
+that is included in the collection, provided that you follow the rules
295
+of this License for verbatim copying of each of the documents in all
296
+other respects.
297
+
298
+You may extract a single document from such a collection, and
299
+distribute it individually under this License, provided you insert a
300
+copy of this License into the extracted document, and follow this
301
+License in all other respects regarding verbatim copying of that
302
+document.
303
+
304
+
305
+7. AGGREGATION WITH INDEPENDENT WORKS
306
+
307
+A compilation of the Document or its derivatives with other separate
308
+and independent documents or works, in or on a volume of a storage or
309
+distribution medium, is called an "aggregate" if the copyright
310
+resulting from the compilation is not used to limit the legal rights
311
+of the compilation's users beyond what the individual works permit.
312
+When the Document is included in an aggregate, this License does not
313
+apply to the other works in the aggregate which are not themselves
314
+derivative works of the Document.
315
+
316
+If the Cover Text requirement of section 3 is applicable to these
317
+copies of the Document, then if the Document is less than one half of
318
+the entire aggregate, the Document's Cover Texts may be placed on
319
+covers that bracket the Document within the aggregate, or the
320
+electronic equivalent of covers if the Document is in electronic form.
321
+Otherwise they must appear on printed covers that bracket the whole
322
+aggregate.
323
+
324
+
325
+8. TRANSLATION
326
+
327
+Translation is considered a kind of modification, so you may
328
+distribute translations of the Document under the terms of section 4.
329
+Replacing Invariant Sections with translations requires special
330
+permission from their copyright holders, but you may include
331
+translations of some or all Invariant Sections in addition to the
332
+original versions of these Invariant Sections.  You may include a
333
+translation of this License, and all the license notices in the
334
+Document, and any Warranty Disclaimers, provided that you also include
335
+the original English version of this License and the original versions
336
+of those notices and disclaimers.  In case of a disagreement between
337
+the translation and the original version of this License or a notice
338
+or disclaimer, the original version will prevail.
339
+
340
+If a section in the Document is Entitled "Acknowledgements",
341
+"Dedications", or "History", the requirement (section 4) to Preserve
342
+its Title (section 1) will typically require changing the actual
343
+title.
344
+
345
+
346
+9. TERMINATION
347
+
348
+You may not copy, modify, sublicense, or distribute the Document
349
+except as expressly provided under this License.  Any attempt
350
+otherwise to copy, modify, sublicense, or distribute it is void, and
351
+will automatically terminate your rights under this License.
352
+
353
+However, if you cease all violation of this License, then your license
354
+from a particular copyright holder is reinstated (a) provisionally,
355
+unless and until the copyright holder explicitly and finally
356
+terminates your license, and (b) permanently, if the copyright holder
357
+fails to notify you of the violation by some reasonable means prior to
358
+60 days after the cessation.
359
+
360
+Moreover, your license from a particular copyright holder is
361
+reinstated permanently if the copyright holder notifies you of the
362
+violation by some reasonable means, this is the first time you have
363
+received notice of violation of this License (for any work) from that
364
+copyright holder, and you cure the violation prior to 30 days after
365
+your receipt of the notice.
366
+
367
+Termination of your rights under this section does not terminate the
368
+licenses of parties who have received copies or rights from you under
369
+this License.  If your rights have been terminated and not permanently
370
+reinstated, receipt of a copy of some or all of the same material does
371
+not give you any rights to use it.
372
+
373
+
374
+10. FUTURE REVISIONS OF THIS LICENSE
375
+
376
+The Free Software Foundation may publish new, revised versions of the
377
+GNU Free Documentation License from time to time.  Such new versions
378
+will be similar in spirit to the present version, but may differ in
379
+detail to address new problems or concerns.  See
380
+https://www.gnu.org/licenses/.
381
+
382
+Each version of the License is given a distinguishing version number.
383
+If the Document specifies that a particular numbered version of this
384
+License "or any later version" applies to it, you have the option of
385
+following the terms and conditions either of that specified version or
386
+of any later version that has been published (not as a draft) by the
387
+Free Software Foundation.  If the Document does not specify a version
388
+number of this License, you may choose any version ever published (not
389
+as a draft) by the Free Software Foundation.  If the Document
390
+specifies that a proxy can decide which future versions of this
391
+License can be used, that proxy's public statement of acceptance of a
392
+version permanently authorizes you to choose that version for the
393
+Document.
394
+
395
+11. RELICENSING
396
+
397
+"Massive Multiauthor Collaboration Site" (or "MMC Site") means any
398
+World Wide Web server that publishes copyrightable works and also
399
+provides prominent facilities for anybody to edit those works.  A
400
+public wiki that anybody can edit is an example of such a server.  A
401
+"Massive Multiauthor Collaboration" (or "MMC") contained in the site
402
+means any set of copyrightable works thus published on the MMC site.
403
+
404
+"CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0 
405
+license published by Creative Commons Corporation, a not-for-profit 
406
+corporation with a principal place of business in San Francisco, 
407
+California, as well as future copyleft versions of that license 
408
+published by that same organization.
409
+
410
+"Incorporate" means to publish or republish a Document, in whole or in 
411
+part, as part of another Document.
412
+
413
+An MMC is "eligible for relicensing" if it is licensed under this 
414
+License, and if all works that were first published under this License 
415
+somewhere other than this MMC, and subsequently incorporated in whole or 
416
+in part into the MMC, (1) had no cover texts or invariant sections, and 
417
+(2) were thus incorporated prior to November 1, 2008.
418
+
419
+The operator of an MMC Site may republish an MMC contained in the site
420
+under CC-BY-SA on the same site at any time before August 1, 2009,
421
+provided the MMC is eligible for relicensing.
422
+

+
424
+ADDENDUM: How to use this License for your documents
425
+
426
+To use this License in a document you have written, include a copy of
427
+the License in the document and put the following copyright and
428
+license notices just after the title page:
429
+
430
+    Copyright (c)  YEAR  YOUR NAME.
431
