11*4882a593Smuzhiyun
12*4882a593SmuzhiyunThe purpose of this License is to make a manual, textbook, or other
13*4882a593Smuzhiyunwritten document "free" in the sense of freedom: to assure everyone
14*4882a593Smuzhiyunthe effective freedom to copy and redistribute it, with or without
15*4882a593Smuzhiyunmodifying it, either commercially or noncommercially.  Secondarily,
16*4882a593Smuzhiyunthis License preserves for the author and publisher a way to get
17*4882a593Smuzhiyuncredit for their work, while not being considered responsible for
18*4882a593Smuzhiyunmodifications made by others.
19*4882a593Smuzhiyun
20*4882a593SmuzhiyunThis License is a kind of "copyleft", which means that derivative
21*4882a593Smuzhiyunworks of the document must themselves be free in the same sense.  It
22*4882a593Smuzhiyuncomplements the GNU General Public License, which is a copyleft
23*4882a593Smuzhiyunlicense designed for free software.
24*4882a593Smuzhiyun
25*4882a593SmuzhiyunWe have designed this License in order to use it for manuals for free
26*4882a593Smuzhiyunsoftware, because free software needs free documentation: a free
27*4882a593Smuzhiyunprogram should come with manuals providing the same freedoms that the
28*4882a593Smuzhiyunsoftware does.  But this License is not limited to software manuals;
29*4882a593Smuzhiyunit can be used for any textual work, regardless of subject matter or
30*4882a593Smuzhiyunwhether it is published as a printed book.  We recommend this License
31*4882a593Smuzhiyunprincipally for works whose purpose is instruction or reference.
32*4882a593Smuzhiyun
33*4882a593Smuzhiyun
34*4882a593Smuzhiyun1. APPLICABILITY AND DEFINITIONS
35*4882a593Smuzhiyun
36*4882a593SmuzhiyunThis License applies to any manual or other work that contains a
37*4882a593Smuzhiyunnotice placed by the copyright holder saying it can be distributed
38*4882a593Smuzhiyununder the terms of this License.  The "Document", below, refers to any
39*4882a593Smuzhiyunsuch manual or work.  Any member of the public is a licensee, and is
40*4882a593Smuzhiyunaddressed as "you".
41*4882a593Smuzhiyun
42*4882a593SmuzhiyunA "Modified Version" of the Document means any work containing the
43*4882a593SmuzhiyunDocument or a portion of it, either copied verbatim, or with
44*4882a593Smuzhiyunmodifications and/or translated into another language.
45*4882a593Smuzhiyun
46*4882a593SmuzhiyunA "Secondary Section" is a named appendix or a front-matter section of
47*4882a593Smuzhiyunthe Document that deals exclusively with the relationship of the
48*4882a593Smuzhiyunpublishers or authors of the Document to the Document's overall subject
49*4882a593Smuzhiyun(or to related matters) and contains nothing that could fall directly
50*4882a593Smuzhiyunwithin that overall subject.  (For example, if the Document is in part a
51*4882a593Smuzhiyuntextbook of mathematics, a Secondary Section may not explain any
52*4882a593Smuzhiyunmathematics.)  The relationship could be a matter of historical
53*4882a593Smuzhiyunconnection with the subject or with related matters, or of legal,
54*4882a593Smuzhiyuncommercial, philosophical, ethical or political position regarding
55*4882a593Smuzhiyunthem.
56*4882a593Smuzhiyun
57*4882a593SmuzhiyunThe "Invariant Sections" are certain Secondary Sections whose titles
58*4882a593Smuzhiyunare designated, as being those of Invariant Sections, in the notice
59*4882a593Smuzhiyunthat says that the Document is released under this License.
60*4882a593Smuzhiyun
61*4882a593SmuzhiyunThe "Cover Texts" are certain short passages of text that are listed,
62*4882a593Smuzhiyunas Front-Cover Texts or Back-Cover Texts, in the notice that says that
63*4882a593Smuzhiyunthe Document is released under this License.
64*4882a593Smuzhiyun
65*4882a593SmuzhiyunA "Transparent" copy of the Document means a machine-readable copy,
66*4882a593Smuzhiyunrepresented in a format whose specification is available to the
67*4882a593Smuzhiyungeneral public, whose contents can be viewed and edited directly and
68*4882a593Smuzhiyunstraightforwardly with generic text editors or (for images composed of
69*4882a593Smuzhiyunpixels) generic paint programs or (for drawings) some widely available
70*4882a593Smuzhiyundrawing editor, and that is suitable for input to text formatters or
71*4882a593Smuzhiyunfor automatic translation to a variety of formats suitable for input
72*4882a593Smuzhiyunto text formatters.  A copy made in an otherwise Transparent file
73*4882a593Smuzhiyunformat whose markup has been designed to thwart or discourage
74*4882a593Smuzhiyunsubsequent modification by readers is not Transparent.  A copy that is
75*4882a593Smuzhiyunnot "Transparent" is called "Opaque".
76*4882a593Smuzhiyun
77*4882a593SmuzhiyunExamples of suitable formats for Transparent copies include plain
78*4882a593SmuzhiyunASCII without markup, Texinfo input format, LaTeX input format, SGML
79*4882a593Smuzhiyunor XML using a publicly available DTD, and standard-conforming simple
80*4882a593SmuzhiyunHTML designed for human modification.  Opaque formats include
81*4882a593SmuzhiyunPostScript, PDF, proprietary formats that can be read and edited only
82*4882a593Smuzhiyunby proprietary word processors, SGML or XML for which the DTD and/or
83*4882a593Smuzhiyunprocessing tools are not generally available, and the
84*4882a593Smuzhiyunmachine-generated HTML produced by some word processors for output
85*4882a593Smuzhiyunpurposes only.
86*4882a593Smuzhiyun
87*4882a593SmuzhiyunThe "Title Page" means, for a printed book, the title page itself,
88*4882a593Smuzhiyunplus such following pages as are needed to hold, legibly, the material
89*4882a593Smuzhiyunthis License requires to appear in the title page.  For works in
90*4882a593Smuzhiyunformats which do not have any title page as such, "Title Page" means
91*4882a593Smuzhiyunthe text near the most prominent appearance of the work's title,
92*4882a593Smuzhiyunpreceding the beginning of the body of the text.
93*4882a593Smuzhiyun
94*4882a593Smuzhiyun
95*4882a593Smuzhiyun2. VERBATIM COPYING
96*4882a593Smuzhiyun
97*4882a593SmuzhiyunYou may copy and distribute the Document in any medium, either
98*4882a593Smuzhiyuncommercially or noncommercially, provided that this License, the
99*4882a593Smuzhiyuncopyright notices, and the license notice saying this License applies
100*4882a593Smuzhiyunto the Document are reproduced in all copies, and that you add no other
101*4882a593Smuzhiyunconditions whatsoever to those of this License.  You may not use
102*4882a593Smuzhiyuntechnical measures to obstruct or control the reading or further
103*4882a593Smuzhiyuncopying of the copies you make or distribute.  However, you may accept
104*4882a593Smuzhiyuncompensation in exchange for copies.  If you distribute a large enough
105*4882a593Smuzhiyunnumber of copies you must also follow the conditions in section 3.
106*4882a593Smuzhiyun
107*4882a593SmuzhiyunYou may also lend copies, under the same conditions stated above, and
108*4882a593Smuzhiyunyou may publicly display copies.
109*4882a593Smuzhiyun
110*4882a593Smuzhiyun
111*4882a593Smuzhiyun3. COPYING IN QUANTITY
112*4882a593Smuzhiyun
113*4882a593SmuzhiyunIf you publish printed copies of the Document numbering more than 100,
114*4882a593Smuzhiyunand the Document's license notice requires Cover Texts, you must enclose
115*4882a593Smuzhiyunthe copies in covers that carry, clearly and legibly, all these Cover
116*4882a593SmuzhiyunTexts: Front-Cover Texts on the front cover, and Back-Cover Texts on
117*4882a593Smuzhiyunthe back cover.  Both covers must also clearly and legibly identify
118*4882a593Smuzhiyunyou as the publisher of these copies.  The front cover must present
119*4882a593Smuzhiyunthe full title with all words of the title equally prominent and
120*4882a593Smuzhiyunvisible.  You may add other material on the covers in addition.
121*4882a593SmuzhiyunCopying with changes limited to the covers, as long as they preserve
122*4882a593Smuzhiyunthe title of the Document and satisfy these conditions, can be treated
123*4882a593Smuzhiyunas verbatim copying in other respects.
124*4882a593Smuzhiyun
125*4882a593SmuzhiyunIf the required texts for either cover are too voluminous to fit
126*4882a593Smuzhiyunlegibly, you should put the first ones listed (as many as fit
127*4882a593Smuzhiyunreasonably) on the actual cover, and continue the rest onto adjacent
128*4882a593Smuzhiyunpages.
129*4882a593Smuzhiyun
130*4882a593SmuzhiyunIf you publish or distribute Opaque copies of the Document numbering
131*4882a593Smuzhiyunmore than 100, you must either include a machine-readable Transparent
132*4882a593Smuzhiyuncopy along with each Opaque copy, or state in or with each Opaque copy
133*4882a593Smuzhiyuna publicly-accessible computer-network location containing a complete
134*4882a593SmuzhiyunTransparent copy of the Document, free of added material, which the
135*4882a593Smuzhiyungeneral network-using public has access to download anonymously at no
136*4882a593Smuzhiyuncharge using public-standard network protocols.  If you use the latter
137*4882a593Smuzhiyunoption, you must take reasonably prudent steps, when you begin
138*4882a593Smuzhiyundistribution of Opaque copies in quantity, to ensure that this
139*4882a593SmuzhiyunTransparent copy will remain thus accessible at the stated location
140*4882a593Smuzhiyununtil at least one year after the last time you distribute an Opaque
141*4882a593Smuzhiyuncopy (directly or through your agents or retailers) of that edition to
142*4882a593Smuzhiyunthe public.
143*4882a593Smuzhiyun
144*4882a593SmuzhiyunIt is requested, but not required, that you contact the authors of the
145*4882a593SmuzhiyunDocument well before redistributing any large number of copies, to give
146*4882a593Smuzhiyunthem a chance to provide you with an updated version of the Document.
147*4882a593Smuzhiyun
148*4882a593Smuzhiyun
149*4882a593Smuzhiyun4. MODIFICATIONS
150*4882a593Smuzhiyun
151*4882a593SmuzhiyunYou may copy and distribute a Modified Version of the Document under
152*4882a593Smuzhiyunthe conditions of sections 2 and 3 above, provided that you release
153*4882a593Smuzhiyunthe Modified Version under precisely this License, with the Modified
154*4882a593SmuzhiyunVersion filling the role of the Document, thus licensing distribution
155*4882a593Smuzhiyunand modification of the Modified Version to whoever possesses a copy
156*4882a593Smuzhiyunof it.  In addition, you must do these things in the Modified Version:
157*4882a593Smuzhiyun
158*4882a593SmuzhiyunA. Use in the Title Page (and on the covers, if any) a title distinct
159*4882a593Smuzhiyun   from that of the Document, and from those of previous versions
160*4882a593Smuzhiyun   (which should, if there were any, be listed in the History section
161*4882a593Smuzhiyun   of the Document).  You may use the same title as a previous version
162*4882a593Smuzhiyun   if the original publisher of that version gives permission.
163*4882a593SmuzhiyunB. List on the Title Page, as authors, one or more persons or entities
164*4882a593Smuzhiyun   responsible for authorship of the modifications in the Modified
165*4882a593Smuzhiyun   Version, together with at least five of the principal authors of the
166*4882a593Smuzhiyun   Document (all of its principal authors, if it has less than five).
167*4882a593SmuzhiyunC. State on the Title page the name of the publisher of the
168*4882a593Smuzhiyun   Modified Version, as the publisher.
169*4882a593SmuzhiyunD. Preserve all the copyright notices of the Document.
170*4882a593SmuzhiyunE. Add an appropriate copyright notice for your modifications
171*4882a593Smuzhiyun   adjacent to the other copyright notices.
172*4882a593SmuzhiyunF. Include, immediately after the copyright notices, a license notice
173*4882a593Smuzhiyun   giving the public permission to use the Modified Version under the
174*4882a593Smuzhiyun   terms of this License, in the form shown in the Addendum below.
175*4882a593SmuzhiyunG. Preserve in that license notice the full lists of Invariant Sections
176*4882a593Smuzhiyun   and required Cover Texts given in the Document's license notice.
177*4882a593SmuzhiyunH. Include an unaltered copy of this License.
178*4882a593SmuzhiyunI. Preserve the section entitled "History", and its title, and add to
179*4882a593Smuzhiyun   it an item stating at least the title, year, new authors, and
180*4882a593Smuzhiyun   publisher of the Modified Version as given on the Title Page.  If
181*4882a593Smuzhiyun   there is no section entitled "History" in the Document, create one
182*4882a593Smuzhiyun   stating the title, year, authors, and publisher of the Document as
183*4882a593Smuzhiyun   given on its Title Page, then add an item describing the Modified
184*4882a593Smuzhiyun   Version as stated in the previous sentence.
185*4882a593SmuzhiyunJ. Preserve the network location, if any, given in the Document for
186*4882a593Smuzhiyun   public access to a Transparent copy of the Document, and likewise
187*4882a593Smuzhiyun   the network locations given in the Document for previous versions
188*4882a593Smuzhiyun   it was based on.  These may be placed in the "History" section.
189*4882a593Smuzhiyun   You may omit a network location for a work that was published at
190*4882a593Smuzhiyun   least four years before the Document itself, or if the original
191*4882a593Smuzhiyun   publisher of the version it refers to gives permission.
192*4882a593SmuzhiyunK. In any section entitled "Acknowledgements" or "Dedications",
193*4882a593Smuzhiyun   preserve the section's title, and preserve in the section all the
194*4882a593Smuzhiyun   substance and tone of each of the contributor acknowledgements
195*4882a593Smuzhiyun   and/or dedications given therein.
196*4882a593SmuzhiyunL. Preserve all the Invariant Sections of the Document,
197*4882a593Smuzhiyun   unaltered in their text and in their titles.  Section numbers
198*4882a593Smuzhiyun   or the equivalent are not considered part of the section titles.
199*4882a593SmuzhiyunM. Delete any section entitled "Endorsements".  Such a section
200*4882a593Smuzhiyun   may not be included in the Modified Version.
201*4882a593SmuzhiyunN. Do not retitle any existing section as "Endorsements"
202*4882a593Smuzhiyun   or to conflict in title with any Invariant Section.
203*4882a593Smuzhiyun
204*4882a593SmuzhiyunIf the Modified Version includes new front-matter sections or
205*4882a593Smuzhiyunappendices that qualify as Secondary Sections and contain no material
206*4882a593Smuzhiyuncopied from the Document, you may at your option designate some or all
207*4882a593Smuzhiyunof these sections as invariant.  To do this, add their titles to the
208*4882a593Smuzhiyunlist of Invariant Sections in the Modified Version's license notice.
209*4882a593SmuzhiyunThese titles must be distinct from any other section titles.
210*4882a593Smuzhiyun
211*4882a593SmuzhiyunYou may add a section entitled "Endorsements", provided it contains
212*4882a593Smuzhiyunnothing but endorsements of your Modified Version by various
213*4882a593Smuzhiyunparties--for example, statements of peer review or that the text has
214*4882a593Smuzhiyunbeen approved by an organization as the authoritative definition of a
215*4882a593Smuzhiyunstandard.
216*4882a593Smuzhiyun
217*4882a593SmuzhiyunYou may add a passage of up to five words as a Front-Cover Text, and a
218*4882a593Smuzhiyunpassage of up to 25 words as a Back-Cover Text, to the end of the list
219*4882a593Smuzhiyunof Cover Texts in the Modified Version.  Only one passage of
220*4882a593SmuzhiyunFront-Cover Text and one of Back-Cover Text may be added by (or
221*4882a593Smuzhiyunthrough arrangements made by) any one entity.  If the Document already
222*4882a593Smuzhiyunincludes a cover text for the same cover, previously added by you or
223*4882a593Smuzhiyunby arrangement made by the same entity you are acting on behalf of,
224*4882a593Smuzhiyunyou may not add another; but you may replace the old one, on explicit
225*4882a593Smuzhiyunpermission from the previous publisher that added the old one.
226*4882a593Smuzhiyun
227*4882a593SmuzhiyunThe author(s) and publisher(s) of the Document do not by this License
228*4882a593Smuzhiyungive permission to use their names for publicity for or to assert or
229*4882a593Smuzhiyunimply endorsement of any Modified Version.

232*4882a593Smuzhiyun5. COMBINING DOCUMENTS
233*4882a593Smuzhiyun
234*4882a593SmuzhiyunYou may combine the Document with other documents released under this
235*4882a593SmuzhiyunLicense, under the terms defined in section 4 above for modified
236*4882a593Smuzhiyunversions, provided that you include in the combination all of the
237*4882a593SmuzhiyunInvariant Sections of all of the original documents, unmodified, and
238*4882a593Smuzhiyunlist them all as Invariant Sections of your combined work in its
239*4882a593Smuzhiyunlicense notice.
240*4882a593Smuzhiyun
241*4882a593SmuzhiyunThe combined work need only contain one copy of this License, and
242*4882a593Smuzhiyunmultiple identical Invariant Sections may be replaced with a single
243*4882a593Smuzhiyuncopy.  If there are multiple Invariant Sections with the same name but
244*4882a593Smuzhiyundifferent contents, make the title of each such section unique by
245*4882a593Smuzhiyunadding at the end of it, in parentheses, the name of the original
246*4882a593Smuzhiyunauthor or publisher of that section if known, or else a unique number.
247*4882a593SmuzhiyunMake the same adjustment to the section titles in the list of
248*4882a593SmuzhiyunInvariant Sections in the license notice of the combined work.
249*4882a593Smuzhiyun
250*4882a593SmuzhiyunIn the combination, you must combine any sections entitled "History"
251*4882a593Smuzhiyunin the various original documents, forming one section entitled
252*4882a593Smuzhiyun"History"; likewise combine any sections entitled "Acknowledgements",
253*4882a593Smuzhiyunand any sections entitled "Dedications".  You must delete all sections
254*4882a593Smuzhiyunentitled "Endorsements."

258*4882a593Smuzhiyun
259*4882a593SmuzhiyunYou may make a collection consisting of the Document and other documents
260*4882a593Smuzhiyunreleased under this License, and replace the individual copies of this
261*4882a593SmuzhiyunLicense in the various documents with a single copy that is included in
262*4882a593Smuzhiyunthe collection, provided that you follow the rules of this License for
263*4882a593Smuzhiyunverbatim copying of each of the documents in all other respects.
264*4882a593Smuzhiyun
265*4882a593SmuzhiyunYou may extract a single document from such a collection, and distribute
266*4882a593Smuzhiyunit individually under this License, provided you insert a copy of this
267*4882a593SmuzhiyunLicense into the extracted document, and follow this License in all
268*4882a593Smuzhiyunother respects regarding verbatim copying of that document.

273*4882a593SmuzhiyunA compilation of the Document or its derivatives with other separate
274*4882a593Smuzhiyunand independent documents or works, in or on a volume of a storage or
