16 | PREAMBLE
|
---|
17 |
|
---|
18 | The purpose of this License is to make a manual, textbook, or other
|
---|
19 | written document ``free'' in the sense of freedom: to assure everyone
|
---|
20 | the effective freedom to copy and redistribute it, with or without
|
---|
21 | modifying it, either commercially or noncommercially. Secondarily,
|
---|
22 | this License preserves for the author and publisher a way to get
|
---|
23 | credit for their work, while not being considered responsible for
|
---|
24 | modifications made by others.
|
---|
25 |
|
---|
26 | This License is a kind of ``copyleft'', which means that derivative
|
---|
27 | works of the document must themselves be free in the same sense. It
|
---|
28 | complements the GNU General Public License, which is a copyleft
|
---|
29 | license designed for free software.
|
---|
30 |
|
---|
31 | We have designed this License in order to use it for manuals for free
|
---|
32 | software, because free software needs free documentation: a free
|
---|
33 | program should come with manuals providing the same freedoms that the
|
---|
34 | software does. But this License is not limited to software manuals;
|
---|
35 | it can be used for any textual work, regardless of subject matter or
|
---|
36 | whether it is published as a printed book. We recommend this License
|
---|
37 | principally for works whose purpose is instruction or reference.

41 | APPLICABILITY AND DEFINITIONS
|
---|
42 |
|
---|
43 | This License applies to any manual or other work that contains a
|
---|
44 | notice placed by the copyright holder saying it can be distributed
|
---|
45 | under the terms of this License. The ``Document'', below, refers to any
|
---|
46 | such manual or work. Any member of the public is a licensee, and is
|
---|
47 | addressed as ``you.''
|
---|
48 |
|
---|
49 | A ``Modified Version'' of the Document means any work containing the
|
---|
50 | Document or a portion of it, either copied verbatim, or with
|
---|
51 | modifications and/or translated into another language.
|
---|
52 |
|
---|
53 | A ``Secondary Section'' is a named appendix or a front-matter section of
|
---|
54 | the Document that deals exclusively with the relationship of the
|
---|
55 | publishers or authors of the Document to the Document's overall subject
|
---|
56 | (or to related matters) and contains nothing that could fall directly
|
---|
57 | within that overall subject. (For example, if the Document is in part a
|
---|
58 | textbook of mathematics, a Secondary Section may not explain any
|
---|
59 | mathematics.) The relationship could be a matter of historical
|
---|
60 | connection with the subject or with related matters, or of legal,
|
---|
61 | commercial, philosophical, ethical or political position regarding
|
---|
62 | them.
|
---|
63 |
|
---|
64 | The ``Invariant Sections'' are certain Secondary Sections whose titles
|
---|
65 | are designated, as being those of Invariant Sections, in the notice
|
---|
66 | that says that the Document is released under this License.
|
---|
67 |
|
---|
68 | The ``Cover Texts'' are certain short passages of text that are listed,
|
---|
69 | as Front-Cover Texts or Back-Cover Texts, in the notice that says that
|
---|
70 | the Document is released under this License.
|
---|
71 |
|
---|
72 | A ``Transparent'' copy of the Document means a machine-readable copy,
|
---|
73 | represented in a format whose specification is available to the
|
---|
74 | general public, whose contents can be viewed and edited directly and
|
---|
75 | straightforwardly with generic text editors or (for images composed of
|
---|
76 | pixels) generic paint programs or (for drawings) some widely available
|
---|
77 | drawing editor, and that is suitable for input to text formatters or
|
---|
78 | for automatic translation to a variety of formats suitable for input
|
---|
79 | to text formatters. A copy made in an otherwise Transparent file
|
---|
80 | format whose markup has been designed to thwart or discourage
|
---|
81 | subsequent modification by readers is not Transparent. A copy that is
|
---|
82 | not ``Transparent'' is called ``Opaque.''
|
---|
83 |
|
---|
84 | Examples of suitable formats for Transparent copies include plain
|
---|
85 | ASCII without markup, Texinfo input format, LaTeX input format, SGML
|
---|
86 | or XML using a publicly available DTD, and standard-conforming simple
|
---|
87 | HTML designed for human modification. Opaque formats include
|
---|
88 | PostScript, PDF, proprietary formats that can be read and edited only
|
---|
89 | by proprietary word processors, SGML or XML for which the DTD and/or
|
---|
90 | processing tools are not generally available, and the
|
---|
91 | machine-generated HTML produced by some word processors for output
|
---|
92 | purposes only.
|
---|
93 |
|
---|
94 | The ``Title Page'' means, for a printed book, the title page itself,
|
---|
95 | plus such following pages as are needed to hold, legibly, the material
|
---|
96 | this License requires to appear in the title page. For works in
|
---|
97 | formats which do not have any title page as such, ``Title Page'' means
|
---|
98 | the text near the most prominent appearance of the work's title,
|
---|
99 | preceding the beginning of the body of the text.

102 | VERBATIM COPYING
|
---|
103 |
|
---|
104 | You may copy and distribute the Document in any medium, either
|
---|
105 | commercially or noncommercially, provided that this License, the
|
---|
106 | copyright notices, and the license notice saying this License applies
|
---|
107 | to the Document are reproduced in all copies, and that you add no other
|
---|
108 | conditions whatsoever to those of this License. You may not use
|
---|
109 | technical measures to obstruct or control the reading or further
|
---|
110 | copying of the copies you make or distribute. However, you may accept
|
---|
111 | compensation in exchange for copies. If you distribute a large enough
|
---|
112 | number of copies you must also follow the conditions in section 3.
|
---|
113 |
|
---|
114 | You may also lend copies, under the same conditions stated above, and
|
---|
115 | you may publicly display copies.

118 | COPYING IN QUANTITY
|
---|
119 |
|
---|
120 | If you publish printed copies of the Document numbering more than 100,
|
---|
121 | and the Document's license notice requires Cover Texts, you must enclose
|
---|
122 | the copies in covers that carry, clearly and legibly, all these Cover
|
---|
123 | Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
|
---|
124 | the back cover. Both covers must also clearly and legibly identify
|
---|
125 | you as the publisher of these copies. The front cover must present
|
---|
126 | the full title with all words of the title equally prominent and
|
---|
127 | visible. You may add other material on the covers in addition.
|
---|
128 | Copying with changes limited to the covers, as long as they preserve
|
---|
129 | the title of the Document and satisfy these conditions, can be treated
|
---|
130 | as verbatim copying in other respects.
|
---|
131 |
|
---|
132 | If the required texts for either cover are too voluminous to fit
|
---|
133 | legibly, you should put the first ones listed (as many as fit
|
---|
134 | reasonably) on the actual cover, and continue the rest onto adjacent
|
---|
135 | pages.
|
---|
136 |
|
---|
137 | If you publish or distribute Opaque copies of the Document numbering
|
---|
138 | more than 100, you must either include a machine-readable Transparent
|
---|
139 | copy along with each Opaque copy, or state in or with each Opaque copy
|
---|
140 | a publicly-accessible computer-network location containing a complete
|
---|
141 | Transparent copy of the Document, free of added material, which the
|
---|
142 | general network-using public has access to download anonymously at no
|
---|
143 | charge using public-standard network protocols. If you use the latter
|
---|
144 | option, you must take reasonably prudent steps, when you begin
|
---|
145 | distribution of Opaque copies in quantity, to ensure that this
|
---|
146 | Transparent copy will remain thus accessible at the stated location
|
---|
147 | until at least one year after the last time you distribute an Opaque
|
---|
148 | copy (directly or through your agents or retailers) of that edition to
|
---|
149 | the public.
|
---|
150 |
|
---|
151 | It is requested, but not required, that you contact the authors of the
|
---|
152 | Document well before redistributing any large number of copies, to give
|
---|
153 | them a chance to provide you with an updated version of the Document.

158 | You may copy and distribute a Modified Version of the Document under

159 | the conditions of sections 2 and 3 above, provided that you release
|
---|
160 | the Modified Version under precisely this License, with the Modified

---|
161 | Version filling the role of the Document, thus licensing distribution
|
---|
162 | and modification of the Modified Version to whoever possesses a copy
|
---|
163 | of it. In addition, you must do these things in the Modified Version:
|
---|
164 |
|
---|
165 | A. Use in the Title Page (and on the covers, if any) a title distinct
|
---|
166 | from that of the Document, and from those of previous versions
|
---|
167 | (which should, if there were any, be listed in the History section
|
---|
168 | of the Document). You may use the same title as a previous version
|
---|
169 | if the original publisher of that version gives permission.@*
|
---|
170 | B. List on the Title Page, as authors, one or more persons or entities
|
---|
171 | responsible for authorship of the modifications in the Modified
|
---|
172 | Version, together with at least five of the principal authors of the
|
---|
173 | Document (all of its principal authors, if it has less than five).@*
|
---|
174 | C. State on the Title page the name of the publisher of the
|
---|
175 | Modified Version, as the publisher.@*
|
---|
176 | D. Preserve all the copyright notices of the Document.@*
|
---|
177 | E. Add an appropriate copyright notice for your modifications
|
---|
178 | adjacent to the other copyright notices.@*
|
---|
179 | F. Include, immediately after the copyright notices, a license notice
|
---|
180 | giving the public permission to use the Modified Version under the
|
---|
181 | terms of this License, in the form shown in the Addendum below.@*
|
---|
182 | G. Preserve in that license notice the full lists of Invariant Sections
|
---|
183 | and required Cover Texts given in the Document's license notice.@*
|
---|
184 | H. Include an unaltered copy of this License.@*
|
---|
185 | I. Preserve the section entitled ``History'', and its title, and add to
|
---|
186 | it an item stating at least the title, year, new authors, and
|
---|
187 | publisher of the Modified Version as given on the Title Page. If
|
---|
188 | there is no section entitled ``History'' in the Document, create one
|
---|
189 | stating the title, year, authors, and publisher of the Document as
|
---|
190 | given on its Title Page, then add an item describing the Modified
|
---|
191 | Version as stated in the previous sentence.@*
|
---|
192 | J. Preserve the network location, if any, given in the Document for
|
---|
193 | public access to a Transparent copy of the Document, and likewise
|
---|
194 | the network locations given in the Document for previous versions
|
---|
195 | it was based on. These may be placed in the ``History'' section.
|
---|
196 | You may omit a network location for a work that was published at
|
---|
197 | least four years before the Document itself, or if the original
|
---|
198 | publisher of the version it refers to gives permission.@*
|
---|
199 | K. In any section entitled ``Acknowledgements'' or ``Dedications'',
|
---|
200 | preserve the section's title, and preserve in the section all the
|
---|
201 | substance and tone of each of the contributor acknowledgements
|
---|
202 | and/or dedications given therein.@*
|
---|
203 | L. Preserve all the Invariant Sections of the Document,
|
---|
204 | unaltered in their text and in their titles. Section numbers
|
---|
205 | or the equivalent are not considered part of the section titles.@*
|
---|
206 | M. Delete any section entitled ``Endorsements.'' Such a section
|
---|
207 | may not be included in the Modified Version.@*
|
---|
208 | N. Do not retitle any existing section as ``Endorsements''
|
---|
209 | or to conflict in title with any Invariant Section.@*
|
---|
210 | @sp 1
|
---|
211 | If the Modified Version includes new front-matter sections or
|
---|
212 | appendices that qualify as Secondary Sections and contain no material
|
---|
213 | copied from the Document, you may at your option designate some or all
|
---|
214 | of these sections as invariant. To do this, add their titles to the
|
---|
215 | list of Invariant Sections in the Modified Version's license notice.
|
---|
216 | These titles must be distinct from any other section titles.
|
---|
217 |
|
---|
218 | You may add a section entitled ``Endorsements'', provided it contains
|
---|
219 | nothing but endorsements of your Modified Version by various
|
---|
220 | parties--for example, statements of peer review or that the text has

221 | been approved by an organization as the authoritative definition of a

223 |

225 | passage of up to 25 words as a Back-Cover Text, to the end of the list

226 | of Cover Texts in the Modified Version. Only one passage of
|

227 | Front-Cover Text and one of Back-Cover Text may be added by (or
|
---|
228 | through arrangements made by) any one entity. If the Document already
|

229 | includes a cover text for the same cover, previously added by you or

---|
230 | by arrangement made by the same entity you are acting on behalf of,
|
---|
231 | you may not add another; but you may replace the old one, on explicit

232 | permission from the previous publisher that added the old one.

234 | The author(s) and publisher(s) of the Document do not by this License
