<p>This edition of <cite>Formatting
Information</cite> was prompted by the generous help I
have received from <span class="TEX">T<span class="E">E</span>X</span> users too numerous to mention
individually. Shortly after TUGboat published the November
2003 edition, I was reminded by a spate of email of the
fragility of documentation for a system like <span class="LATEX">L<span class="A">A</span><span class="TEX">T<span class="E">E</span>X</span></span> which is
constantly under development. There have been revisions to
packages; issues of new distributions, new tools, and new
interfaces; new books and other new documents; corrections to
my own errors; suggestions for rewording; and in one or two
cases mild abuse for having omitted package X which the author
felt to be indispensable to users. ¶ I am grateful as always to the people who sent me
corrections and suggestions for improvement. Please keep them
coming: only this way can this book reflect what people
want to learn. The same limitation still applies, however: no
mathematics, as there are already a dozen or more excellent
books on the market — as well as other online
documents — dealing with mathematical typesetting in
<span class="TEX">T<span class="E">E</span>X</span> and <span class="LATEX">L<span class="A">A</span><span class="TEX">T<span class="E">E</span>X</span></span> in finer and better detail than I am
capable of. ¶ The structure remains the same, but I have revised and
rephrased a lot of material, especially in the earlier
chapters where a new user cannot be expected yet to have
acquired any depth of knowledge. Many of the screenshots have
been updated, and most of the examples and code fragments have
been retested. ¶ As I was finishing this edition, I was asked to review
an article for <cite><a href="http://www.tug.org/pracjourn/" name="C3">The Prac<span class="TEX">T<span class="E">E</span>X</span> Journal</a></cite>, which
grew out of the Practical <span class="TEX">T<span class="E">E</span>X</span> Conference in 2004. The
author specifically took the writers of documentation to task
for failing to explain things more clearly, and as I read
more, I found myself agreeing, and resolving to clear up some
specific problems areas as far as possible. It is very
difficult for people who write technical documentation to
remember how they struggled to learn what has now become a
familiar system. So much of what we do is second nature, and a
lot of it actually has nothing to do with the software, but
more with the way in which we view and approach information,
and the general level of knowledge of computing. If I have
obscured something by making unreasonable assumptions about
<em>your</em> knowledge, please let me know so
that I can correct it.

<p>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.
</p>
<p>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.
</p>
<p>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.
</p>

<h2><a href="#gfdl"><img src="up.png" title="Chapter Contents" width="32" alt="ToC" align="right" border="0"></a>D.2 <a name="gfdl-1">APPLICABILITY AND DEFINITIONS</a></h2>
<p><a name="gfdl-doc"></a>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.
</p>
<p><a name="gfdl-mod-ver"></a>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.
</p>
<p><a name="gfdl-secnd-sect"></a>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.
</p>
<p><a name="gfdl-inv-sect"></a>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.
</p>
<p><a name="gfdl-cov-text"></a>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.
</p>
<p><a name="gfdl-transparent"></a>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’.
</p>
<p>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 <small><a href="chapter10.html#HTML" class="acroref" name="A306" title="HyperText Markup Language">HTML</a></small>,
<a name="t43">PostScript</a> or PDF designed for human
modification. Examples of transparent image formats include
PNG, XCF and JPG. Opaque formats include proprietary formats

<p><a name="gfdl-title-page"></a>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.
</p>
<p><a name="gfdl-entitled"></a>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.

<p>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.

<h2><a href="#gfdl"><img src="up.png" title="Chapter Contents" width="32" alt="ToC" align="right" border="0"></a>D.3 <a name="gfdl-2">VERBATIM COPYING</a></h2>
<p>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.
</p>
<p>You may also lend copies, under the same conditions stated
above, and you may publicly display copies.
</p>

<div class="sect1">
<h2><a href="#gfdl"><img src="up.png" title="Chapter Contents" width="32" alt="ToC" align="right" border="0"></a>D.4 <a name="gfdl-3">COPYING IN QUANTITY</a></h2>
<p>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.
</p>
<p>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.
</p>
<p>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.
</p>
<p>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.

<p>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:
</p>
<ol type="1">
<li>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.
</li>
<li>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.
</li>
<li>State on the Title page the name of the
publisher of the Modified Version, as the
publisher.
</li>
<li>Preserve all the copyright notices of the
Document.
</li>
<li>Add an appropriate copyright notice for
your modifications adjacent to the other copyright
notices.
</li>
<li>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 <a href="appendixD.html#gfdl-addendum" title="sect1">Addendum</a> below.
</li>
<li>Preserve in that license notice the full
lists of Invariant Sections and required Cover Texts given
in the Document's license
notice.
</li>
<li>Include an unaltered copy of this License.
</li>
<li>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.
</li>
<li>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.
</li>
<li>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.
</li>
<li>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.
</li>
<li>Delete any section Entitled
‘Endorsements’. Such a section may not be
included in the Modified Version.
</li>
<li>Do not retitle any existing section to be
Entitled ‘Endorsements’ or to conflict in
title with any Invariant Section.
</li>
<li>Preserve any Warranty Disclaimers.
</li>
</ol>
<p>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.
</p>
<p>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.
</p>
<p>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.
</p>
<p>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.

<p>You may combine the Document with other documents released
under this License, under the terms defined in <a href="appendixD.html#gfdl-4" title="sect1">section 4</a> 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.
</p>
<p>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.
</p>
<p>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’.

<p>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.
</p>
<p>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.

WORKS</a></h2>
<p>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 an aggregate, this
License does not apply to the other works in the aggregate
which are not themselves derivative works of the
Document.
</p>
<p>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.

<h2><a href="#gfdl"><img src="up.png" title="Chapter Contents" width="32" alt="ToC" align="right" border="0"></a>D.9 <a name="gfdl-8">TRANSLATION</a></h2>
<p>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.
</p>
<p>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.

for your documents</a></h2>
<p>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

</p>
<blockquote class="citation"><a name="K43"> </a><p>

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’.
</p>
</blockquote>
<p>If you have Invariant Sections, Front-Cover Texts and
Back-Cover Texts, replace the
‘with...Texts.’ line with this:
</p>
<blockquote class="citation"><a name="K43"> </a><p>
with the Invariant Sections being LIST THEIR TITLES, with
the Front-Cover Texts being LIST, and with the Back-Cover

<p>If you have Invariant Sections without Cover Texts, or
some other combination of the three, merge those two
alternatives to suit the situation.

<p>If your document contains nontrivial examples of program
code, we recommend releasing these examples in parallel under
