79UAM Text Tools (UTT) is a package of language processing tools
80developed at Adam Mickiewicz University. Its functionality includes:
81
82@itemize @bullet
83
84@item
85tokenization
86@item
87dictionary-based morphological analysis
88@item
89heuristic morphological analysis of unknown words
90@item
91spelling correction
92@item
93pattern search
94@item
95sentence splitting
96@item
97generation of concordance tables
98@end itemize
99
100The toolkit is destined for processing of raw (not annotated)
101unrestricted text for any conceivable purpose.
102
103The system is organized as a collection of command-line programs, each
104performing one operation, e.g. tokenization, lemmatization, spelling
105correction. The components are independent one from another, the
106unifying element being the uniform i/o file format.
107
108The components may be combined in various ways to provide various text
109processing services. Also new components supplied by the used may be
110easily incorporated into the system provided that they respect the i/o
111file format conventions.
112
113UTT component programs does not depend on any specific tagset or
114morphological description format.

136@node    UTT file format
137@chapter UTT file format
138
139A UTT file contains annotation of a text. It consists of a sequence of
140segments. Each segment explicitly refers to a continuous piece of the
141text and provides some information on it.
142
143@section Segment format
144
145A segment occupies one line of a UTT file and consists of
146space-separated fields:
147
148
149@quotation
150@sp 1
151[@var{start} [@var{length}]] @var{type} @var{form} [@var{annotation1} [@var{annotation2} ...]]
152@sp 1
153@end quotation
154
155@table @var
156
157@item @var{start}
158Non-negative integer value indicating the position in the source text where the
159segment starts.
160
161@item @var{length}
162Non-negative integer value indicating the length of the segment.
163
164@item @var{type}
165A sequence of non-ASCII characters (without spaces or letters, which could lead to @var{type} being misinterpreted as a @var{start} or @var{length} field).
166@var{type} reflects the main classification of segments -
167into words, numbers, punctuation marks, meta-text markers.
168@xref{tok output,,tok output}, for description of automatically recognized type markers.
169
170@item @var{form}
171This field contains the textual form of the segment or the special
172symbol @code{*} indicating that the form is not given (e.g. when the segment has been created artificially to mark something and is of lentgh 0).
173
174The characters or character sequences that have special meaning in the
175@var{form} field are enumerated below.
176
177Characters with special meaning:
178
179@itemize
180@item @code{_} - space character
181@item @code{*} - undefined contents
182@end itemize
183
184Escape sequences:
185
186@itemize
187@item @code{\n} - new line
188@item @code{\t} - tabulation
189@item @code{\r} - carriage return 
190
191@item @code{\_} - the @code{_} character
192@item @code{\*} - the @code{*} character
193@item @code{\\} - the @code{\} character
194
195@c @item @code{\hh} - a character with hexadecimal code @code{hh} (used for non-printable characters)
196@end itemize
197
198@item @var{annotation1}
199@item @var{annotation2}
200@item ...
201Annotation fields have the following format:
202
203@var{longname} @code{:} @var{value}
204
205or
206
207@var{shortname} @var{value}
208
209where @var{longname} is a string of alphanumeric characters
210(isalnum() test), @var{shortname} - a single non-alphanumeric character
211(ispunct() test), and @var{value} is an arbitrary string of non-blank characters.
212
213@end table
214
215
216Only two fields are mandatory: @var{type} and @var{form}. All other fields
217may be absent. In the case when only one number precedes the
218@var{type} field, it is interpreted as the @var{START} position.
219
220If the @var{length} field is ommited, the length of the segment is the
221length of the @var{form} field, except when the value of the
222@var{form} field is @code{*} -- in this case, the length is assumed to
223be 0.
224
225If the @var{start} field is also absent, the segment is assumed to directly
226follow the preceding one.
227
228@c Conventions:
229
230@c Annotation fields with predefined meaning:
231
232@c @itemize
233@c @item @code{!} - UTT components are allowed to modify the contents of
234@c the @var{form} field (e.g. spelling correction does this). If this happens the
235@c original form of the segment have to be placed in the @code{!}-field.
236@c @item @code{@@} - morphological description
237@c @item @code{=} - node identifier assignment (used in graph encoding)
238@c @item @code{<} - preceding/dominating node(s) (used in graph encoding)
239@c @item @code{>} - succeeding/subordinate node(s) (used in graph encoding)
240@c @end itemize
241
242Segments of length 0 may be used to mark file positions with some
243information. See e.g. BOS and EOS (beginning/end of sentence) markers
244in the example below.

311@section UTT File
312
313A UTT file consists of a sequence of segments.  The same text position
314may be covered by multiple segments. In cosequence, ambiguous text
315segmentation and ambiguous annotation may be represented.
316
317There are two structural requirements a valid UTT-formatted file
318has to meet:
319
320@itemize @bullet
321
322@item
323segments have to be sorted with respect to the @var{position} field,
324
325@item
326for each
327segment ending at position @var{n}, either there must be a segment starting at
328position @var{n+1}, or position @var{n+1} is not covered by any segment; similarly
329for each segment starting at position @var{n}, either there must be a segment
330ending at position @var{n-1}, or the position @var{n-1} must not be covered
331by any segment.
332
333@end itemize
334
335A valid annotation for the text fragment
336@example
33712.5 km
338@end example
339
340may be
341
342@example
3430000 02 N 12
3440000 04 N 12.5
3450002 01 P .
3460003 01 N 5
3470004 01 S _
3480005 02 W km
349@end example
350
351but not
352
353@example
3540000 02 N 12
3550000 04 N 12.5
3560004 01 S _
3570005 02 W km
358@end example
359
360because in the latter example the first segment (starting at position 0000, 2 characters long) ends at position @var{n}=0001 which is covered by the second segment and no segment starts at position @var{n+2}=0002.
361
362@section Character encoding
363
364The UTT component programs accept only 1-byte character encoding, such
365as ISO, ANSI, DOS, UTF-8 (probably: not tested yet).
366
367
368@c @section Formats
369
370@c @unnumberedsubsubsec Basic format
371
372@c While processing large amounts of the overhead related with explicit
373@c ... of the start position and segment length becomes ... . Therefore,
374@c for efficiency reasons certain shortcuts are possible:
375
376@c @unnumberedsubsubsec Relative start position
377
378@c Start position may be given as relative distance from the last
379@c absolut position.
380
381@c @unnumberedsubsubsec Absent length
382
383@c Segment length may by omitted. Normally it can be restored by counting
384@c the length of the @emph{form field}. For segments with the special value
385@c @code{*} in the @emph{form field} length 0 is assumed.
386
387@c @unnumberedsubsubsec Absent length and start position
388
389@c Both start position and segment length may be omitted. In this format
390@c each segment is assumed to follow the previous one. This format is,
391@c therefore, suitable only for unambiguously tagged text
392@c (0-length markers can be still used.)

613@c This option makes the program print ambiguous annotation in one output
614@c segment. By default when
615@c ambiguous new annotation is being produced for a segment, the segment
616@c is multiplicated and each of the annotations is added to separate copy
617@c of the segment.

627
628Values for all command line options accepted by a component
629may be set in configuration files. The default location of the
630configuration files for a component named @command{@var{program}} are
631
632@example
[246900a]633        @file{/usr/local/etc/utt/@var{program}.conf}
[25ae32e]634@end example

[246900a]639        @file{~/.utt/@var{program}.conf}
[25ae32e]640@end example
641
642for user configuration file.
643
644@c The configuration file to load may be also specified with the
645@c @option{--config} option. Configuration file need not be provided.
646
647For each option, the value is set according to the following priority:
648
649@itemize
650@item command line
651@c @item configuration file indicated with @option{--config} option
652@item user configuration file (or configuration file indicated with the @option{--config} option)
653@item system-wide configuration file
654@end itemize
655
656Parameter values are specified in the following format:
657
658@var{parametername}=@var{value}
659
660where @var{parametername} is the short or long name of an option accepted by
661the program, or
662
663@var{parametername}
664
665if the option does not need arguments.
666
667You can introduce comments to configuration files using the # sign.
668
669If a program accepts multiple occurences of an option (e.g. @var{lem}'s select option) you can specify them in two distinct lines of the program's configuration file.
670
671@c The equal sign may be omitted.
672
673
674@quotation Tip
675If you have two (or more) frequently used sets of options for the same
676program (eg. lem with PMDBF dictionary and lem with a user dictionary)
677a good solution is to create two soft links to lem, called
678eg. lemg and lemu and specify their configuration in files lemg.conf
679and lemu.conf respectively.

1186The spelling corrector applies Kemal Oflazer's dynamic programming
1187algorithm @cite{oflazer96} to the FSA representation of the set of
1188word forms of the Polex/PMDBF dictionary. Given an incorrect
1189word form it returns all word forms present in the dictionary whose
1190edit distance is smaller than the threshold given as the parameter.
1191
1192By default @code{cor} replaces the contents of the @var{form} field
1193with new corrected value, placing the old contents in the @code{cor}
1194field.

1370@subsection Pattern
1371
1372The @command{ser} pattern is a regular expression over terms corresponding
1373to text segments or segment sequences. Predefined terms are:
1374
1375@table @code
1376
1377@item seg(@var{t},@var{f},@var{a})
1378a segment of type @var{t}, containing form @var{f} and annotation
1379@var{a}
1380
1381@item form(@var{f})
1382a segment containing form @var{f}
1383
1384@item field(@var{f})
1385a segment containing annotation field @var{f}
1386
1387@item space(@var{f})
1388a space segment of form @var{f}
1389
1390@item word(@var{f})
1391a word segment of form @var{f}
1392
1393@item punct(@var{f})
1394a punct segment of form @var{f}
1395
1396@item number(@var{f})
1397a number segment of form @var{f}
1398
1399@item lexeme(@var{f})
1400a word segment with lemma @var{f}
1401
1402@item cat(@var{c})
1403a word segment of category @var{c}
1404
1405@end table
1406
1407All arguments are optional. If an argument is omitted, an arbitrary
1408string of non-blank characters is assumed as the argument value. Term
1409arguments may be arbitrary character-level regular expressions. The
1410following special symbols can by used:
1411
1412@multitable {aaaaaaaaaa} {aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa}
1413@item @code{[@dots{}]}            @tab a character class
1414@item @code{[^@dots{}]}           @tab a negated character class
1415@item @code{|}                    @tab alternative
1416@item @code{*}                    @tab repetition, including zero times
1417@item @code{+}                    @tab repetition, at least one time
1418@item @code{?}                    @tab optionality
1419@item @code{@{@var{m},@var{n}@}}  @tab repetition from @var{m} to @var{n} times
1420@item @code{@{@var{m},@}}         @tab repetition @var{m} or more times
1421@item @code{@{@var{m}@}}          @tab repetition @var{m} times
1422@item @code{@var{\ddd}}           @tab the character with octal value @var{ddd}
1423@item @code{\x@var{hh}}           @tab the character with hexadecimal value @var{hh}
1424@item @code{( )}                  @tab parentheses, used to override precedence
1425@c @end multitable
1426
1427@c @multitable {aaa} {aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa}
1428@item @code{.}    @tab a non-blank character
1429@item @code{\w}   @tab a letter
1430@item @code{\W}   @tab a non-blank character other than a letter
1431@item @code{\d}   @tab a digit
1432@item @code{\D}   @tab a non-blank character other than a digit
1433@item @code{\s}   @tab a space or tab character
1434@item @code{\S}   @tab a non-blank character (the same as @code{.})
1435@item @code{\l}   @tab a lowercase letter
1436@item @code{\L}   @tab an uppercase letter
1437@end multitable
1438
1439
1440@noindent The following characters:
1441@example
1442@verb{%  [   ]   ^   |   *   +   ?   {   }   ,   .   <   >   \ %}
1443@end example
1444must be escaped with a backslash, i.e. written as:
1445@example
1446@verb{% \[  \]  \^  \|  \*  \+  \?  \{  \}  \,  \.  \<  \>  \\ %}
1447@end example
1448
1449@quotation Note
1450The special symbols are ... borrowed from Perl with minor
1451modifications ... for convenience
1452The meaning of certain special characters/sequences slightly differs
1453from their common ???. This is motivated by convenience reasons.
1454The meaning of the @code{.} special character is modified due to
1455the special function of spaces in utt files (they are field
1456separators). Use @code{\s} to explicitly
1457@end quotation
1458
1459In the argument of the @code{cat} term a special operator <...> may be
1460used. A category specification enclosed in angle brackets matches all
1461category descriptions which are consistent (non-contradictory) with the
1462specification. For example @code{<N>} matches all noun descriptions,
1463@code{<ADJ/Can>} matches all adjectives in accusative or nominal case.

1822@item AT&T FSM Library,
1823@item AT&T Lextools.
1824@end itemize
1825
1826In order for the compiledic program to work you have to install the
1827above mentioned packages into your system.  They are freely available
1828for non-commercial use.
1829
1830Usage:
1831@example
1832        compiledic <dictionaryname>.dic
1833@end example
1834
1835The file <dictionaryname>.bin will be generated.
1836
1837Remarque: The program produces a lot of temporary files which are
1838stored in the current directory. They are deleted after successfull
1839termination of the program.

1857
1858@command{fla} ``flattens'' a utt file by merging segments belonging
1859to one sentence in one line. Technically, end-of-line characters
1860('\n', ASCII code 10) are replaced with line-feed characters ('\f',
1861ASCII code 12).  The flattening makes it possible to process UTT files
1862with such tools as @command{grep} or @command{sed} sentence by
1863sentence (used in @command{grp} and @command{mar}).
1864
1865Flattened files should have the suffix @code{.fla}, eg. @file{thetext.utt.fla}.
1866
1867Flattened files are still human-readible.
1868
1869Usage:
1870
1871@example
1872        fla [<bosregex>]
1873@end example
1874
1875The facultative argument is a regular expression describing segments
1876which should be treated as sentence beginnings (the test is: the
1877segment contains a fragment matching the @code{<bosregex>}). By
1878default, segments containing a field @code{BOS} are seeked.

1991Usually, one performs repetitively search over the same corpus. In
1992such case it is advisable to transform the corpus data into the format
1993required by @command{grp} first, and then use the preprocessed data.
1994
1995As @command{grp} (@command{grep}) processes data faster then it is
1996read from the disk drive, the search time may be still shortened by
1997using file compression techniques.  We suggest usin @command{lzop}.

2230The purpose of this License is to make a manual, textbook, or other
2231functional and useful document @dfn{free} in the sense of freedom: to
2232assure everyone the effective freedom to copy and redistribute it,
2233with or without modifying it, either commercially or noncommercially.
2234Secondarily, this License preserves for the author and publisher a way
2235to get credit for their work, while not being considered responsible
2236for modifications made by others.
2237
2238This License is a kind of ``copyleft'', which means that derivative
2239works of the document must themselves be free in the same sense.  It
2240complements the GNU General Public License, which is a copyleft
2241license designed for free software.
2242
2243We have designed this License in order to use it for manuals for free
2244software, because free software needs free documentation: a free
2245program should come with manuals providing the same freedoms that the
2246software does.  But this License is not limited to software manuals;
2247it can be used for any textual work, regardless of subject matter or
2248whether it is published as a printed book.  We recommend this License
2249principally for works whose purpose is instruction or reference.

2252APPLICABILITY AND DEFINITIONS
2253
2254This License applies to any manual or other work, in any medium, that
2255contains a notice placed by the copyright holder saying it can be
2256distributed under the terms of this License.  Such a notice grants a
2257world-wide, royalty-free license, unlimited in duration, to use that
2258work under the conditions stated herein.  The ``Document'', below,
2259refers to any such manual or work.  Any member of the public is a
2260licensee, and is addressed as ``you''.  You accept the license if you
2261copy, modify or distribute the work in a way requiring permission
2262under copyright law.
2263
2264A ``Modified Version'' of the Document means any work containing the
2265Document or a portion of it, either copied verbatim, or with
2266modifications and/or translated into another language.
2267
2268A ``Secondary Section'' is a named appendix or a front-matter section
2269of the Document that deals exclusively with the relationship of the
2270publishers or authors of the Document to the Document's overall
2271subject (or to related matters) and contains nothing that could fall
2272directly within that overall subject.  (Thus, if the Document is in
2273part a textbook of mathematics, a Secondary Section may not explain
2274any mathematics.)  The relationship could be a matter of historical
2275connection with the subject or with related matters, or of legal,
2276commercial, philosophical, ethical or political position regarding
2277them.
2278
2279The ``Invariant Sections'' are certain Secondary Sections whose titles
2280are designated, as being those of Invariant Sections, in the notice
2281that says that the Document is released under this License.  If a
2282section does not fit the above definition of Secondary then it is not
2283allowed to be designated as Invariant.  The Document may contain zero
2284Invariant Sections.  If the Document does not identify any Invariant
2285Sections then there are none.
2286
2287The ``Cover Texts'' are certain short passages of text that are listed,
2288as Front-Cover Texts or Back-Cover Texts, in the notice that says that
2289the Document is released under this License.  A Front-Cover Text may
2290be at most 5 words, and a Back-Cover Text may be at most 25 words.
2291
2292A ``Transparent'' copy of the Document means a machine-readable copy,
2293represented in a format whose specification is available to the
2294general public, that is suitable for revising the document
2295straightforwardly with generic text editors or (for images composed of
2296pixels) generic paint programs or (for drawings) some widely available
2297drawing editor, and that is suitable for input to text formatters or
2298for automatic translation to a variety of formats suitable for input
2299to text formatters.  A copy made in an otherwise Transparent file
2300format whose markup, or absence of markup, has been arranged to thwart
2301or discourage subsequent modification by readers is not Transparent.
2302An image format is not Transparent if used for any substantial amount
2303of text.  A copy that is not ``Transparent'' is called ``Opaque''.
2304
2305Examples of suitable formats for Transparent copies include plain
2306@sc{ascii} without markup, Texinfo input format, La@TeX{} input
2307format, @acronym{SGML} or @acronym{XML} using a publicly available
2308@acronym{DTD}, and standard-conforming simple @acronym{HTML},
2309PostScript or @acronym{PDF} designed for human modification.  Examples
2310of transparent image formats include @acronym{PNG}, @acronym{XCF} and
2311@acronym{JPG}.  Opaque formats include proprietary formats that can be
2312read and edited only by proprietary word processors, @acronym{SGML} or
2313@acronym{XML} for which the @acronym{DTD} and/or processing tools are
2314not generally available, and the machine-generated @acronym{HTML},
2315PostScript or @acronym{PDF} produced by some word processors for
2316output purposes only.
2317
2318The ``Title Page'' means, for a printed book, the title page itself,
2319plus such following pages as are needed to hold, legibly, the material
2320this License requires to appear in the title page.  For works in
2321formats which do not have any title page as such, ``Title Page'' means
2322the text near the most prominent appearance of the work's title,
2323preceding the beginning of the body of the text.
2324
2325A section ``Entitled XYZ'' means a named subunit of the Document whose
2326title either is precisely XYZ or contains XYZ in parentheses following
2327text that translates XYZ in another language.  (Here XYZ stands for a
2328specific section name mentioned below, such as ``Acknowledgements'',
2329``Dedications'', ``Endorsements'', or ``History''.)  To ``Preserve the Title''
2330of such a section when you modify the Document means that it remains a
2331section ``Entitled XYZ'' according to this definition.
2332
2333The Document may include Warranty Disclaimers next to the notice which
2334states that this License applies to the Document.  These Warranty
2335Disclaimers are considered to be included by reference in this
2336License, but only as regards disclaiming warranties: any other
2337implication that these Warranty Disclaimers may have is void and has
2338no effect on the meaning of this License.

2340@item
2341VERBATIM COPYING
2342
2343You may copy and distribute the Document in any medium, either
2344commercially or noncommercially, provided that this License, the
2345copyright notices, and the license notice saying this License applies
2346to the Document are reproduced in all copies, and that you add no other
2347conditions whatsoever to those of this License.  You may not use
2348technical measures to obstruct or control the reading or further
2349copying of the copies you make or distribute.  However, you may accept
2350compensation in exchange for copies.  If you distribute a large enough
2351number of copies you must also follow the conditions in section 3.
2352
2353You may also lend copies, under the same conditions stated above, and
2354you may publicly display copies.
2355
2356@item
2357COPYING IN QUANTITY
2358
2359If you publish printed copies (or copies in media that commonly have
2360printed covers) of the Document, numbering more than 100, and the
2361Document's license notice requires Cover Texts, you must enclose the
2362copies in covers that carry, clearly and legibly, all these Cover
2363Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
2364the back cover.  Both covers must also clearly and legibly identify
2365you as the publisher of these copies.  The front cover must present
2366the full title with all words of the title equally prominent and
2367visible.  You may add other material on the covers in addition.
2368Copying with changes limited to the covers, as long as they preserve
2369the title of the Document and satisfy these conditions, can be treated
2370as verbatim copying in other respects.
2371
2372If the required texts for either cover are too voluminous to fit
2373legibly, you should put the first ones listed (as many as fit
2374reasonably) on the actual cover, and continue the rest onto adjacent
2375pages.
2376
2377If you publish or distribute Opaque copies of the Document numbering
2378more than 100, you must either include a machine-readable Transparent
2379copy along with each Opaque copy, or state in or with each Opaque copy
2380a computer-network location from which the general network-using
2381public has access to download using public-standard network protocols
2382a complete Transparent copy of the Document, free of added material.
2383If you use the latter option, you must take reasonably prudent steps,
2384when you begin distribution of Opaque copies in quantity, to ensure
2385that this Transparent copy will remain thus accessible at the stated
2386location until at least one year after the last time you distribute an
2387Opaque copy (directly or through your agents or retailers) of that
2388edition to the public.
2389
2390It is requested, but not required, that you contact the authors of the
2391Document well before redistributing any large number of copies, to give
2392them a chance to provide you with an updated version of the Document.
2393
2394@item
2395MODIFICATIONS
2396
2397You may copy and distribute a Modified Version of the Document under
2398the conditions of sections 2 and 3 above, provided that you release
2399the Modified Version under precisely this License, with the Modified
2400Version filling the role of the Document, thus licensing distribution
2401and modification of the Modified Version to whoever possesses a copy
2402of it.  In addition, you must do these things in the Modified Version:
2403
2404@enumerate A
2405@item
2406Use in the Title Page (and on the covers, if any) a title distinct
2407from that of the Document, and from those of previous versions
2408(which should, if there were any, be listed in the History section
2409of the Document).  You may use the same title as a previous version
2410if the original publisher of that version gives permission.
2411
2412@item
2413List on the Title Page, as authors, one or more persons or entities
2414responsible for authorship of the modifications in the Modified
2415Version, together with at least five of the principal authors of the
2416Document (all of its principal authors, if it has fewer than five),
2417unless they release you from this requirement.
2418
2419@item
2420State on the Title page the name of the publisher of the
2421Modified Version, as the publisher.
2422
2423@item
2424Preserve all the copyright notices of the Document.
2425
2426@item
2427Add an appropriate copyright notice for your modifications
2428adjacent to the other copyright notices.
2429
2430@item
2431Include, immediately after the copyright notices, a license notice
2432giving the public permission to use the Modified Version under the
2433terms of this License, in the form shown in the Addendum below.
2434
2435@item
2436Preserve in that license notice the full lists of Invariant Sections
2437and required Cover Texts given in the Document's license notice.
2438
2439@item
2440Include an unaltered copy of this License.
2441
2442@item
2443Preserve the section Entitled ``History'', Preserve its Title, and add
2444to it an item stating at least the title, year, new authors, and
2445publisher of the Modified Version as given on the Title Page.  If
2446there is no section Entitled ``History'' in the Document, create one
2447stating the title, year, authors, and publisher of the Document as
2448given on its Title Page, then add an item describing the Modified
2449Version as stated in the previous sentence.
2450
2451@item
2452Preserve the network location, if any, given in the Document for
2453public access to a Transparent copy of the Document, and likewise
2454the network locations given in the Document for previous versions
2455it was based on.  These may be placed in the ``History'' section.
2456You may omit a network location for a work that was published at
2457least four years before the Document itself, or if the original
2458publisher of the version it refers to gives permission.
2459
2460@item
2461For any section Entitled ``Acknowledgements'' or ``Dedications'', Preserve
2462the Title of the section, and preserve in the section all the
2463substance and tone of each of the contributor acknowledgements and/or
2464dedications given therein.
2465
2466@item
2467Preserve all the Invariant Sections of the Document,
2468unaltered in their text and in their titles.  Section numbers
2469or the equivalent are not considered part of the section titles.
2470
2471@item
2472Delete any section Entitled ``Endorsements''.  Such a section
2473may not be included in the Modified Version.
2474
2475@item
2476Do not retitle any existing section to be Entitled ``Endorsements'' or
2477to conflict in title with any Invariant Section.
2478
2479@item
2480Preserve any Warranty Disclaimers.
2481@end enumerate
2482
2483If the Modified Version includes new front-matter sections or
2484appendices that qualify as Secondary Sections and contain no material
2485copied from the Document, you may at your option designate some or all
2486of these sections as invariant.  To do this, add their titles to the
2487list of Invariant Sections in the Modified Version's license notice.
2488These titles must be distinct from any other section titles.
2489
2490You may add a section Entitled ``Endorsements'', provided it contains
2491nothing but endorsements of your Modified Version by various
2492parties---for example, statements of peer review or that the text has
2493been approved by an organization as the authoritative definition of a
2494standard.
2495
2496You may add a passage of up to five words as a Front-Cover Text, and a
2497passage of up to 25 words as a Back-Cover Text, to the end of the list
2498of Cover Texts in the Modified Version.  Only one passage of
2499Front-Cover Text and one of Back-Cover Text may be added by (or
2500through arrangements made by) any one entity.  If the Document already
2501includes a cover text for the same cover, previously added by you or
2502by arrangement made by the same entity you are acting on behalf of,
2503you may not add another; but you may replace the old one, on explicit
2504permission from the previous publisher that added the old one.
2505
2506The author(s) and publisher(s) of the Document do not by this License
2507give permission to use their names for publicity for or to assert or
2508imply endorsement of any Modified Version.
2509
2510@item
2511COMBINING DOCUMENTS
2512
2513You may combine the Document with other documents released under this
2514License, under the terms defined in section 4 above for modified
2515versions, provided that you include in the combination all of the
2516Invariant Sections of all of the original documents, unmodified, and
2517list them all as Invariant Sections of your combined work in its
2518license notice, and that you preserve all their Warranty Disclaimers.
2519
2520The combined work need only contain one copy of this License, and
2521multiple identical Invariant Sections may be replaced with a single
2522copy.  If there are multiple Invariant Sections with the same name but
2523different contents, make the title of each such section unique by
2524adding at the end of it, in parentheses, the name of the original
2525author or publisher of that section if known, or else a unique number.
2526Make the same adjustment to the section titles in the list of
2527Invariant Sections in the license notice of the combined work.
2528
2529In the combination, you must combine any sections Entitled ``History''
2530in the various original documents, forming one section Entitled
2531``History''; likewise combine any sections Entitled ``Acknowledgements'',
2532and any sections Entitled ``Dedications''.  You must delete all
2533sections Entitled ``Endorsements.''
2534
2535@item
2536COLLECTIONS OF DOCUMENTS
2537
2538You may make a collection consisting of the Document and other documents
2539released under this License, and replace the individual copies of this
2540License in the various documents with a single copy that is included in
2541the collection, provided that you follow the rules of this License for
2542verbatim copying of each of the documents in all other respects.
2543
2544You may extract a single document from such a collection, and distribute
2545it individually under this License, provided you insert a copy of this
2546License into the extracted document, and follow this License in all
2547other respects regarding verbatim copying of that document.
2548
2549@item
2550AGGREGATION WITH INDEPENDENT WORKS
2551
2552A compilation of the Document or its derivatives with other separate
2553and independent documents or works, in or on a volume of a storage or
2554distribution medium, is called an ``aggregate'' if the copyright
2555resulting from the compilation is not used to limit the legal rights
2556of the compilation's users beyond what the individual works permit.
2557When the Document is included in an aggregate, this License does not
2558apply to the other works in the aggregate which are not themselves
2559derivative works of the Document.
2560
2561If the Cover Text requirement of section 3 is applicable to these
2562copies of the Document, then if the Document is less than one half of
2563the entire aggregate, the Document's Cover Texts may be placed on
2564covers that bracket the Document within the aggregate, or the
2565electronic equivalent of covers if the Document is in electronic form.
2566Otherwise they must appear on printed covers that bracket the whole
2567aggregate.
2568
2569@item
2570TRANSLATION
2571
2572Translation is considered a kind of modification, so you may
2573distribute translations of the Document under the terms of section 4.
2574Replacing Invariant Sections with translations requires special
2575permission from their copyright holders, but you may include
2576translations of some or all Invariant Sections in addition to the
2577original versions of these Invariant Sections.  You may include a
2578translation of this License, and all the license notices in the
2579Document, and any Warranty Disclaimers, provided that you also include
2580the original English version of this License and the original versions
2581of those notices and disclaimers.  In case of a disagreement between
2582the translation and the original version of this License or a notice
2583or disclaimer, the original version will prevail.
2584
2585If a section in the Document is Entitled ``Acknowledgements'',
2586``Dedications'', or ``History'', the requirement (section 4) to Preserve
2587its Title (section 1) will typically require changing the actual
2588title.
2589
2590@item
2591TERMINATION
2592
2593You may not copy, modify, sublicense, or distribute the Document except
2594as expressly provided for under this License.  Any other attempt to
2595copy, modify, sublicense or distribute the Document is void, and will
2596automatically terminate your rights under this License.  However,
2597parties who have received copies, or rights, from you under this
2598License will not have their licenses terminated so long as such
2599parties remain in full compliance.
2600
2601@item
2602FUTURE REVISIONS OF THIS LICENSE
2603
2604The Free Software Foundation may publish new, revised versions
2605of the GNU Free Documentation License from time to time.  Such new
2606versions will be similar in spirit to the present version, but may
2607differ in detail to address new problems or concerns.  See
2608@uref{http://www.gnu.org/copyleft/}.
2609
2610Each version of the License is given a distinguishing version number.
2611If the Document specifies that a particular numbered version of this
2612License ``or any later version'' applies to it, you have the option of
2613following the terms and conditions either of that specified version or
2614of any later version that has been published (not as a draft) by the
2615Free Software Foundation.  If the Document does not specify a version
2616number of this License, you may choose any version ever published (not
2617as a draft) by the Free Software Foundation.

2621@heading ADDENDUM: How to use this License for your documents
2622
2623To use this License in a document you have written, include a copy of
2624the License in the document and put the following copyright and
2625license notices just after the title page:
2626
2627@smallexample
2628@group
2629  Copyright (C)  @var{year}  @var{your name}.
2630  Permission is granted to copy, distribute and/or modify this document
2631  under the terms of the GNU Free Documentation License, Version 1.2
2632  or any later version published by the Free Software Foundation;
2633  with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
2634  Texts.  A copy of the license is included in the section entitled ``GNU
2635  Free Documentation License''.
2636@end group
2637@end smallexample
2638
2639If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
2640replace the ``with@dots{}Texts.'' line with this:
2641
2642@smallexample
2643@group
2644    with the Invariant Sections being @var{list their titles}, with
2645    the Front-Cover Texts being @var{list}, and with the Back-Cover Texts
2646    being @var{list}.
2647@end group
2648@end smallexample
2649
2650If you have Invariant Sections without Cover Texts, or some other
2651combination of the three, merge those two alternatives to suit the
2652situation.
2653
2654If your document contains nontrivial examples of program code, we
2655recommend releasing these examples in parallel under your choice of
2656free software license, such as the GNU General Public License,
2657to permit their use in free software.
