9: 59 Temple Place, Suite 330, Boston, MA 02111-1307, USA
10:
11: Everyone is permitted to copy and distribute verbatim copies
12: of this license document, but changing it is not allowed.

17: PREAMBLE
18:
19: The purpose of this License is to make a manual, textbook, or other
20: written document @dfn{free} in the sense of freedom: to assure everyone
21: the effective freedom to copy and redistribute it, with or without
22: modifying it, either commercially or noncommercially. Secondarily,
23: this License preserves for the author and publisher a way to get
24: credit for their work, while not being considered responsible for
25: modifications made by others.
26:
27: This License is a kind of ``copyleft'', which means that derivative
28: works of the document must themselves be free in the same sense. It
29: complements the GNU General Public License, which is a copyleft
30: license designed for free software.
31:
32: We have designed this License in order to use it for manuals for free
33: software, because free software needs free documentation: a free
34: program should come with manuals providing the same freedoms that the
35: software does. But this License is not limited to software manuals;
36: it can be used for any textual work, regardless of subject matter or
37: whether it is published as a printed book. We recommend this License
38: principally for works whose purpose is instruction or reference.
39:
40: @item
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: @sc{ascii} without markup, Texinfo input format, La@TeX{} input format,
86: @acronym{SGML} or @acronym{XML} using a publicly available
87: @acronym{DTD}, and standard-conforming simple @acronym{HTML} designed
88: for human modification. Opaque formats include PostScript,
89: @acronym{PDF}, proprietary formats that can be read and edited only by
90: proprietary word processors, @acronym{SGML} or @acronym{XML} for which
91: the @acronym{DTD} and/or processing tools are not generally available,
92: and the machine-generated @acronym{HTML} produced by some word
93: processors for output purposes only.
94:
95: The ``Title Page'' means, for a printed book, the title page itself,
96: plus such following pages as are needed to hold, legibly, the material
97: this License requires to appear in the title page. For works in
98: formats which do not have any title page as such, ``Title Page'' means
99: the text near the most prominent appearance of the work's title,
100: preceding the beginning of the body of the text.
101:
102: @item
103: VERBATIM COPYING
104:
105: You may copy and distribute the Document in any medium, either
106: commercially or noncommercially, provided that this License, the
107: copyright notices, and the license notice saying this License applies
108: to the Document are reproduced in all copies, and that you add no other
109: conditions whatsoever to those of this License. You may not use
110: technical measures to obstruct or control the reading or further
111: copying of the copies you make or distribute. However, you may accept
112: compensation in exchange for copies. If you distribute a large enough
113: number of copies you must also follow the conditions in section 3.
114:
115: You may also lend copies, under the same conditions stated above, and
116: you may publicly display copies.
117:
118: @item
119: COPYING IN QUANTITY
120:
121: If you publish printed copies of the Document numbering more than 100,
122: and the Document's license notice requires Cover Texts, you must enclose
123: the copies in covers that carry, clearly and legibly, all these Cover
124: Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
125: the back cover. Both covers must also clearly and legibly identify
126: you as the publisher of these copies. The front cover must present
127: the full title with all words of the title equally prominent and
128: visible. You may add other material on the covers in addition.
129: Copying with changes limited to the covers, as long as they preserve
130: the title of the Document and satisfy these conditions, can be treated
131: as verbatim copying in other respects.
132:
133: If the required texts for either cover are too voluminous to fit
134: legibly, you should put the first ones listed (as many as fit
135: reasonably) on the actual cover, and continue the rest onto adjacent
136: pages.
137:
138: If you publish or distribute Opaque copies of the Document numbering
139: more than 100, you must either include a machine-readable Transparent
140: copy along with each Opaque copy, or state in or with each Opaque copy
141: a publicly-accessible computer-network location containing a complete
142: Transparent copy of the Document, free of added material, which the
143: general network-using public has access to download anonymously at no
144: charge using public-standard network protocols. If you use the latter
145: option, you must take reasonably prudent steps, when you begin
146: distribution of Opaque copies in quantity, to ensure that this
147: Transparent copy will remain thus accessible at the stated location
148: until at least one year after the last time you distribute an Opaque
149: copy (directly or through your agents or retailers) of that edition to
150: the public.
151:
152: It is requested, but not required, that you contact the authors of the
153: Document well before redistributing any large number of copies, to give
154: them a chance to provide you with an updated version of the Document.
155:
156: @item
157: MODIFICATIONS
158:
159: You may copy and distribute a Modified Version of the Document under
160: the conditions of sections 2 and 3 above, provided that you release
161: the Modified Version under precisely this License, with the Modified
162: Version filling the role of the Document, thus licensing distribution
163: and modification of the Modified Version to whoever possesses a copy
164: of it. In addition, you must do these things in the Modified Version:
165:
166: @enumerate A
167: @item
168: Use in the Title Page (and on the covers, if any) a title distinct
169: from that of the Document, and from those of previous versions
170: (which should, if there were any, be listed in the History section
171: of the Document). You may use the same title as a previous version
172: if the original publisher of that version gives permission.
173:
174: @item
175: List on the Title Page, as authors, one or more persons or entities
176: responsible for authorship of the modifications in the Modified
177: Version, together with at least five of the principal authors of the
178: Document (all of its principal authors, if it has less than five).
179:
180: @item
181: State on the Title page the name of the publisher of the
182: Modified Version, as the publisher.
183:
184: @item
185: Preserve all the copyright notices of the Document.
186:
187: @item
188: Add an appropriate copyright notice for your modifications
189: adjacent to the other copyright notices.
190:
191: @item
192: Include, immediately after the copyright notices, a license notice
193: giving the public permission to use the Modified Version under the
194: terms of this License, in the form shown in the Addendum below.
195:
196: @item
197: Preserve in that license notice the full lists of Invariant Sections
198: and required Cover Texts given in the Document's license notice.
199:
200: @item
201: Include an unaltered copy of this License.
202:
203: @item
204: Preserve the section entitled ``History'', and its title, and add to
205: it an item stating at least the title, year, new authors, and
206: publisher of the Modified Version as given on the Title Page. If
207: there is no section entitled ``History'' in the Document, create one
208: stating the title, year, authors, and publisher of the Document as
209: given on its Title Page, then add an item describing the Modified
210: Version as stated in the previous sentence.
211:
212: @item
213: Preserve the network location, if any, given in the Document for
214: public access to a Transparent copy of the Document, and likewise
215: the network locations given in the Document for previous versions
216: it was based on. These may be placed in the ``History'' section.
217: You may omit a network location for a work that was published at
218: least four years before the Document itself, or if the original
219: publisher of the version it refers to gives permission.
220:
221: @item
222: In any section entitled ``Acknowledgments'' or ``Dedications'',
223: preserve the section's title, and preserve in the section all the
224: substance and tone of each of the contributor acknowledgments
225: and/or dedications given therein.
226:
227: @item
228: Preserve all the Invariant Sections of the Document,
229: unaltered in their text and in their titles. Section numbers
230: or the equivalent are not considered part of the section titles.
231:
232: @item
233: Delete any section entitled ``Endorsements''. Such a section
234: may not be included in the Modified Version.
235:
236: @item
237: Do not retitle any existing section as ``Endorsements''
238: or to conflict in title with any Invariant Section.
239: @end enumerate
240:
241: If the Modified Version includes new front-matter sections or
242: appendices that qualify as Secondary Sections and contain no material
243: copied from the Document, you may at your option designate some or all
244: of these sections as invariant. To do this, add their titles to the
245: list of Invariant Sections in the Modified Version's license notice.
246: These titles must be distinct from any other section titles.
247:
248: You may add a section entitled ``Endorsements'', provided it contains
249: nothing but endorsements of your Modified Version by various
250: parties---for example, statements of peer review or that the text has
251: been approved by an organization as the authoritative definition of a
252: standard.
253:
254: You may add a passage of up to five words as a Front-Cover Text, and a
255: passage of up to 25 words as a Back-Cover Text, to the end of the list
256: of Cover Texts in the Modified Version. Only one passage of
257: Front-Cover Text and one of Back-Cover Text may be added by (or
258: through arrangements made by) any one entity. If the Document already
259: includes a cover text for the same cover, previously added by you or
260: by arrangement made by the same entity you are acting on behalf of,
261: you may not add another; but you may replace the old one, on explicit
262: permission from the previous publisher that added the old one.
263:
264: The author(s) and publisher(s) of the Document do not by this License
265: give permission to use their names for publicity for or to assert or
266: imply endorsement of any Modified Version.
267:
268: @item
269: COMBINING DOCUMENTS
270:
271: You may combine the Document with other documents released under this
272: License, under the terms defined in section 4 above for modified
273: versions, provided that you include in the combination all of the
274: Invariant Sections of all of the original documents, unmodified, and
275: list them all as Invariant Sections of your combined work in its
276: license notice.
277:
278: The combined work need only contain one copy of this License, and
279: multiple identical Invariant Sections may be replaced with a single
280: copy. If there are multiple Invariant Sections with the same name but
281: different contents, make the title of each such section unique by
282: adding at the end of it, in parentheses, the name of the original
283: author or publisher of that section if known, or else a unique number.
284: Make the same adjustment to the section titles in the list of
285: Invariant Sections in the license notice of the combined work.
286:
287: In the combination, you must combine any sections entitled ``History''
288: in the various original documents, forming one section entitled
289: ``History''; likewise combine any sections entitled ``Acknowledgments'',
290: and any sections entitled ``Dedications''. You must delete all sections
291: entitled ``Endorsements.''
292:
293: @item
294: COLLECTIONS OF DOCUMENTS
295:
296: You may make a collection consisting of the Document and other documents
297: released under this License, and replace the individual copies of this
298: License in the various documents with a single copy that is included in
299: the collection, provided that you follow the rules of this License for
300: verbatim copying of each of the documents in all other respects.
301:
302: You may extract a single document from such a collection, and distribute
303: it individually under this License, provided you insert a copy of this
304: License into the extracted document, and follow this License in all
305: other respects regarding verbatim copying of that document.
306:
307: @item
308: AGGREGATION WITH INDEPENDENT WORKS
309:
310: A compilation of the Document or its derivatives with other separate
311: and independent documents or works, in or on a volume of a storage or
312: distribution medium, does not as a whole count as a Modified Version
313: of the Document, provided no compilation copyright is claimed for the
314: compilation. Such a compilation is called an ``aggregate'', and this
315: License does not apply to the other self-contained works thus compiled
316: with the Document, on account of their being thus compiled, if they
317: are not themselves derivative works of the Document.
318:
319: If the Cover Text requirement of section 3 is applicable to these
320: copies of the Document, then if the Document is less than one quarter
321: of the entire aggregate, the Document's Cover Texts may be placed on
322: covers that surround only the Document within the aggregate.
323: Otherwise they must appear on covers around the whole aggregate.
324:
325: @item
326: TRANSLATION
327:
328: Translation is considered a kind of modification, so you may
329: distribute translations of the Document under the terms of section 4.
330: Replacing Invariant Sections with translations requires special
331: permission from their copyright holders, but you may include
332: translations of some or all Invariant Sections in addition to the
333: original versions of these Invariant Sections. You may include a
334: translation of this License provided that you also include the
335: original English version of this License. In case of a disagreement
336: between the translation and the original English version of this
337: License, the original English version will prevail.
338:
339: @item
340: TERMINATION
341:
342: You may not copy, modify, sublicense, or distribute the Document except
343: as expressly provided for under this License. Any other attempt to
344: copy, modify, sublicense or distribute the Document is void, and will
345: automatically terminate your rights under this License. However,
346: parties who have received copies, or rights, from you under this
347: License will not have their licenses terminated so long as such
348: parties remain in full compliance.
349:
350: @item
351: FUTURE REVISIONS OF THIS LICENSE
352:
353: The Free Software Foundation may publish new, revised versions
354: of the GNU Free Documentation License from time to time. Such new
355: versions will be similar in spirit to the present version, but may
356: differ in detail to address new problems or concerns. See
357: @uref{http://www.gnu.org/copyleft/}.
358:
359: Each version of the License is given a distinguishing version number.
360: If the Document specifies that a particular numbered version of this
361: License ``or any later version'' applies to it, you have the option of
362: following the terms and conditions either of that specified version or
363: of any later version that has been published (not as a draft) by the
364: Free Software Foundation. If the Document does not specify a version
365: number of this License, you may choose any version ever published (not
366: as a draft) by the Free Software Foundation.

370: @appendixsubsec ADDENDUM: How to use this License for your documents
371:
372: To use this License in a document you have written, include a copy of
373: the License in the document and put the following copyright and
374: license notices just after the title page:
375:

381: or any later version published by the Free Software Foundation;
382: with the Invariant Sections being @var{list their titles}, with the
383: Front-Cover Texts being @var{list}, and with the Back-Cover Texts being @var{list}.
384: A copy of the license is included in the section entitled ``GNU
385: Free Documentation License''.
386: @end group
387: @end smallexample
388:
389: If you have no Invariant Sections, write ``with no Invariant Sections''
390: instead of saying which ones are invariant. If you have no
391: Front-Cover Texts, write ``no Front-Cover Texts'' instead of
392: ``Front-Cover Texts being @var{list}''; likewise for Back-Cover Texts.
393:
394: If your document contains nontrivial examples of program code, we
395: recommend releasing these examples in parallel under your choice of
396: free software license, such as the GNU General Public License,
397: to permit their use in free software.
