1.2.  Software described in this document.

TeX handles only the formatting part of the document preparation.
Generating output from TeX is like compiling source code into object
code, which still needs to be linked.  You prepare an input file with
a text editor----what most people think of as word processing''---
and format the input file document with TeX to produce a device-
independent output file, called a .dvi file.

You also need a program or two to translate TeX's .dvi output for your
screen and printer.  These programs are collectively known as
dviware.''  For example, TeX itself only makes requests for fonts.
It is up to the .dvi output translator to provide the actual font for
the output regardless of whether the medium is a video screen or
paper.  This extra step may seem overly complicated, but the
abstraction allows documents to display the same on different devices
with little or no change to the original document.

1.2.1.  teTeX.

TeX is implemented for practically every serious computer system in
the world---and quite a few non-serious'' ones---so implementors
must provide the installation facilities for all of them.  This
accounts in part for teTeX's complexity, in addition to the inherent
complexity of any TeX installation.  It also accounts for the fact
that installing the system yourself is a significant task, and unless
you are already familiar with TeX, it is easy to get lost in the
numerous executable programs, TeX files, documentation, and fonts.

Fortunately, teTeX is part of the GNU/Linux distribution. You can
install the package much more easily using GNU/Linux installation
tools. You may already have teTeX installed on your system.  If so,
you can skip ahead to Section Using teTeX''.

However, if you want to install the package, the archives necessary
for a workable teTeX installation are on the CTAN archive network.
There is a list of these sites in Section CTAN site list''.

CTAN is the Comprehensive TeX Archive Network, a series of anonymous
FTP sites that archive TeX programs, macros, fonts, and documentation.
In the course of using TeX you'll probably become familiar with at
least one CTAN site.  In this document, a pathname like
~CTAN/contrib/pstricks means look in the directory contrib/pstricks

The installation of the generic teTeX distribution described in
Section Installing the CTAN teTeX distribution'' concentrates on the
Intel versions of Linux.  Installing teTeX on other hardware should
require only substituting the appropriate executable program archive
in the installation process.

In addition to the executable programs, the distribution includes all
of the TeX and LaTeX package, metafont and its sources, bibtex,
makeindex, and all of the documentation... more than 4 megabytes'
worth.  The documentation covers everything you will forseeably need
to know to get started.  So, you should install all of the documents.
Not only will you eventually read them, the documents themselves
provide many examples of live'' TeX and LaTeX code.

TeX was written by Professor Donald Knuth of Stanford University.  It
is a lower-level typesetting language for all of the higher-level
packages like LaTeX.  Essentially, LaTeX is a set of TeX macros that
provide convenient, predefined document formats for end users.  If you
like the formats provided by LaTeX, you may never need to learn bare-
bones TeX programming.  The difference between the two languages is
like the difference between assembly language and C.  You can have the
speed and flexibility of TeX, or the convenience of LaTeX.

By the way, the letters of the word TeX'' are Greek, tau-epsilon-
chi.  It is not a fraternity, but the root of the Greek word, techne,
which means art and/or science.  TeX'' is not pronounced like the
first syllable in Texas.''  The chi has no English equivalent, but
TeX is generally pronounced so that it rhymes with yecch,'' to use
Professor Knuth's example from The TeXBook, which is one of the
standard TeX references.  When writing, TeX,'' on character devices,
always use the standard capitalization, or the \TeX{} macro in
typesetting.

1.2.2.  Text editors.

Any of the editors that work under Linux---jed, joe, jove, vi, vim,
stevie, Emacs, and microemacs---will work to prepare a TeX input file,
as long as the editor reads and writes plain-vanilla ASCII text.  My
preference is GNU Emacs.  There are several reasons for this:

·  You can format, preview and print documents with Emacs's TeX and
LaTeX modes.

·  Emacs can automatically insert TeX-style, curly quotes,'' as you
type, rather than the "ASCII-vanilla" kind.

·  Emacs has integrated support for Texinfo, a hypertext documentation
system.

·  Emacs is widely supported.  Versions 19.34 and later, for example,
are included in the major U.S. Linux distributions.  The most

·  Emacs does everything except butter the toast in the morning.

·  Emacs is free.

1.2.3.  dvips .

Tomas Rokicki's dvips generates Postscript from a .dvi file.  In
addition, it runs Metafont if necessary to generate the bit mapped
fonts it needs or uses Postscript fonts for the output.  It can also
crop and resize pages and perform graphics translations from
instructions in a TeX or LaTeX file,

The dvips program is part of the teTeX distribution.  It is discussed
fully in Section Mixing text and graphics with <tt>dvips</tt>''

1.2.4.  Fonts.

Much of TeX's, and therefore LaTeX's, complexity, arises from its
implementation of various font systems, and the way these fonts are
specified.  A major improvement of LaTeX 2e over its predecessor was
the way users specify fonts, the former New Font Selection Scheme.
They're discussed in Section Characters and type styles'', Section
TeX Font Commands'', and Section Using Postscript fonts''.)

which is enough to get you started.  Also provided are the font
metrics descriptions, in .tfm (TeX font metric) files.  To generate
the other fonts that you need, it is simply a matter of installing the
metafont sources.  teTeX's .dvi utilities will invoke metafont
automatically and generate the Computer Modern fonts you need.

2.  Using teTeX.

Theoretically, at least, everything is installed correctly and is
ready to run.  teTeX is a very large software package.  As with any
complex software package, you'll want to start by learning teTeX
slowly, instead of being overwhelmed by its complexity.

At the same time, we want the software to do something useful.  So

Hello, World!''

as Professor Knuth suggests, we'll produce a couple of teTeX's own
documents in order to test it.

2.1.  Printing the documentation.

You should be logged in as root the first few times you run teTeX.  If
you aren't, Metafont may not be able to create the necessary
directories for its fonts.  The texconfig program includes an option
to make the font directories world-writable, but if you're working on
a multi-user system, security considerations may make this option
impractical or undesirable.

In either instance, if you don't have the appropriate permissions to
write to the directories where the fonts are stored, Metafont will
complain loudly because it can't make the directories.  You won't see
any output because you have a bunch of zero-length font characters.
This is no problem.  Simply log out, re-login as root, and repeat the
offending operation.

The nice thing about teTeX is that, if you blow it, no real harm is
done.  It's not like a compiler, where, say, you will trash the root
partition if a pointer goes astray.  What, you haven't read the teTeX
manual yet?  Of course you haven't.  It's still in the distribution,
in source code form, waiting to be output.

So, without further delay, you will want to read the teTeX manual.
It's located in the directory

/usr/lib/teTeX/texmf/doc/tetex.

The LaTeX source for the manual is called TETEXDOC.tex.  (The .tex
extension is used for both TeX and LaTeX files.  Some editors, like
Emacs, can tell the difference.)  There is also a file TETEXDOC.dvi
included with the distribution, which you might want to keep in a safe
place---say, another directory ---in case you want to test your .dvi
drivers later.  With that out of the way, type

latex TETEXDOC.tex

LaTeX will print several warnings.  The first,

LaTeX Warning: Label(s) may have changed. Rerun to get the
cross-references right.

LaTeXing the document twice.  So, repeat the command.  The other warn­
ings can be safely ignored.  They simply are informing you that some
of the FTP paths mentioned in the documentation are too wide for their
alloted spaces.  Sections Paragraph styles and dimensions'' and
Tolerances'' describe horizontal spacing in more detail.

teTeX will have generated several files from TETEXDOC.tex.  The one
that we're interested in is TETEXDOC.dvi. This is the device-
independent output which you can send either to the screen or the
printer.  If you're running teTeX under the X Windows System, you can
preview the document with xdvi.

For the present, let's assume that you have a HP LaserJet II.  You
would give the command

dvilj2 TETEXDOC.dvi

which writes a PCL output file from TETEXDOC.dvi, including soft fonts
which will be downloaded to the LaserJet.  This is not a feature of
TeX or LaTeX, but a feature provided by dvilj2.  Other .dvi drivers
provide features that are relevant to the devices they support.
dvilj2 tries to fill the font requests which were made in the original
LaTeX document with the the closest equivalents available on the sys­
tem.  In the case of a plain text document like TETEXDOC.tex, there
isn't much difficulty.  All of the fonts requested by TETEXDOC.tex
will be generated by metafont, which is automatically invoked by
dvilj2, if the fonts aren't already present.  (If you're running
dvilj2 for the first time, the program may need to generate all of the
fonts.)  There are several options that control font generation via
dvilj2.  They're outlined in the manual page.  At this point, you
shouldn't need to operate metafont directly.  If you do, then some­
thing has gone awry with your installation.  All of the .dvi drivers
will invoke metafont directly via the kpathsea path-searching
library---the discussion of which is beyond the scope of this docu­
ment---and you don't need to do any more work with metafont for the
present---all of the metafont sources for the Computer Modern font
library are provided.

You can print TETEXDOC.lj with the command

lpr TETEXDOC.lj

You may also need to install a printer filter that understands PCL.

The nine-page teTeX Guide provides some useful information for further
configuring your system, some of which I have mentioned, much that
this document doesn't cover.

Some of the information in the next section I haven't been able to
test, because I have a non-Postscript HP Deskjet 400 color ink jet
printer connected to the computer's parallel port.  However, not
owning a Postscript printer is no barrier to printing text and
graphics from your text documents.  Ghostscript is available in most

3.  TeX commands.

Preparing documents for TeX typesetting is easy.  Make sure there's a
blank line between the paragraphs of a plain text file, and run file
through the TeX program with the command

tex your_text_file

The result will be a file of the same base name and the extension
.dvi.  TeX formats the text in 10-point, Computer Modern Roman, sin­
gle-spaced, with justified left and right margins.  If you receive
error messages from special characters like dollar signs, escape them
with a backslash character, \, and run TeX on the file again.  You
should be able to process the resulting file with the .dvi file trans­
lator of your choice (see above) to get printed output.

One peculiarity of TeX input is that you must use opening and closing
quotes, which are denoted in the input file with the grave accent and
single quote characters.  Emacs' TeX mode does this for you
automatically.

"These are ASCII-type quotes."
These are TeX-style' quotes.''

3.1.  Command overview.

Commands in TeX start with a backslash (\'').  For example, the
command to change the spacing between lines is

\baselineskip=24pt

The baseline is the bottom of the characters on a line, not counting
descenders.  The distance between the baseline of one line and the
next is the \baselineskip, and is assigned a value of 24 points.

Measurements or dimensions in TeX are often given in the following
units:

pt                % Point        1/72 in.
pc                % Pica:        12 pt.
in                % Inch:        72.27 pt.
cm                % Centimeter:  2.54 cm = 1 in.
mm                % Millimeter:  10 mm = 1 cm.

Some commands do not take assignments.  For example:

\smallskip        % Approximately 3 pt.
\medskip          % Two \smallskips.
\bigskip         % Two \medskips.

A \smallskip inserts a 3 pt. vertical space in the document.  The
measurements are approximate because TeX needs to adjust the
dimensions for page breaks, section headings, and other units of
vertical space.  This is true for horizontal spacing as well.

\hsize=6.5in

This command sets the line length to a width of 6.5 inches.  TeX tries
to fill the line by adjusting the spacing between words, and some let­
ters.  If TeX cannot fill a line to within its tolerances, it produces
a warning message, and adjusts the horizontal spacing within the line
as best it can.  Formatting tolerances are discussed in Section Tol­
erances''.

There are many other commands that specify horizontal and vertical
dimensions and tolerances, and the most commonly use commands are
described below.

3.2.  Font commands.

In TeX, the default font is 10 pt. Computer Modern Roman.  To specify
a typeface, like italic, bold, or monospaced, use the following
commands.

\rm          % Roman (the default).
\it          % Italics.
\bf         % Bold.
\tt         % Monospaced (teletype).
\sl          % Oblique (slanted).

The commands change the typeface where they appear in the text, as in
this example.

This text is Roman, \it and this text is italic.  \bf This text is
bold, and \rm this text is in Roman again.

To specify a font for your document, use the\font command.

\font\romantwelve=cmr12

This creates the font command \romantwelve, which, when used in the
text, changes the font to Computer Modern Roman, 12 point.

\romantwelve
This is the Computer Modern Roman font at 12 points.

For information about the fonts in the teTeX distribution look at the
file:

/usr/lib/teTeX/texmf/doc/fonts/fontname/fontname.dvi

If you want to print a sample of a font, TeX the file

/usr/lib/teTeX/texmf/tex/plain/base/fontchart.tex

and fill in the name of the font you want to print at the prompt.

You can also change the size of a font to get different effects.  Font
magnification is exponential, and specified with the scaled \magstep
command, which is placed after the font specification.

\font\sfmedium=cmss12 scaled \magstep 1

This command will give you a sans serif font that is 120 percent the
size of the 12-point Computer Modern sans serif font.  Fonts can be
magnified in steps from 0 to 5.  Each step provides and additional 120
percent magnification.

3.3.  Paragraph styles and dimensions.

As mentioned above, TeX typesets text in 10-point Computer Modern
Roman by default.  The length of a line is the value of \hsize, which
defaults to 6.5 in.  If you want to change the value of \hsize to 5.5
in. for example, use this command.

\hsize=5.5in

In TeX a dimension is an adjustable unit of length, either horizontal
or vertical.  The amount by which a dimension can be increased or
decreased can be specified in its definition.  Closely related to a
dimension is a skip, which is a dimension that is placed in one of
TeX's internal registers.  Skips are defined with the \newskip
command.  The \smallskip dimension, as defined by TeX is:

\newskip\smallskipamount \smallskipamount=3pt plus 1pt minus 1pt

The \smallskip command is shorthand for:

\vskip\smallskipamount

There are a number of dimensions that control the page layout.  They
are summarized in Section Page layout''.

TeX formats paragraphs with justified left and right margins.  If you
want the text to be left justified only, use this command:

\raggedright

To typeset a line that is justified to the right margin, use the
\rightline command:

\rightline{This is the line to be typeset.}

The \line command typesets the text of its argument to fill the entire
line.

\line{This text will be spaced to fit the entire line.}

The \hfil command adds space to fill out the line where it occurs.
So, for example, the \rightline command is equivalent to:

\line{\hfilThis line will be right justified.}

To typeset a line that is centered, use the \centerline command.

\centerline{This is the line to be centered.}

To change the left margin, set the value of \hoffset, as in this
example:

\hoffset=1.5in

The \parindent command specifies the amount that the first line of
every paragraph is indented.

\parindent=.5in

Two other dimensions, \leftskip and \rightskip, will indent the right
and left margins, respectively, of the paragraphs that come after
them.

\leftskip=.5in
\rightskip=.5in

The control word \narrower is equivalent to:

\leftskip=\parindent
\rightskip=\parindent

That is, \narrower narrows the paragraph margins by the value of
\parindent

As mentioned in the previous section, the \baselineskip specifies the
distance between lines.  The default is 12 pt.  To approximate double-
spaced text, use the following command.

\baselineskip=\baselineskip*1.6

The \parskip command specifies the distance in addition to
\baselineskip between paragraphs.  By default, no extra space is
added, but the distance between paragraphs can stretch as much as 1
pt. to fill the page correctly.  To put a blank line between
paragraphs, use this command:

\parskip=\baselineskip

3.3.1.  Tolerances.  (What are those black rectangles after every
line?)

TeX normally formats text to strict tolerances.  If, for some reason,
text cannot be formatted to within those tolerances, TeX produces a
warning message and formats the text the best it can.  If the text
must be stretched too much to fit the line, TeX warns you that the
\hbox is underfull.  Text that must be squeezed to fit in the line
produces an overfull \hbox warning.

For each overfull \hbox, TeX places a slug, a black rectangle, after
the line.  The slug indicates that the line could not be formatted to
within the specifications set by the \hbadness parameter.

The fit of the text within its specified dimensions is measured by its
badness, which is a number between 0 and 10000.  A badness of 0 is a
perfect fit, and a badness of 10000 means that the line probably will
never fit.  The default value of \hbadness is 1000.  If you set
\hbadness to 10000, TeX does not report underfull lines.

Sometimes TeX allows a line to extend past the right margin.  This is
an aesthetic decision on the part of TeX's author.  The amount is
determined by the \hfuzz parameter, which defaults to 0.1 pt.  If the
text does not fit within the line, the \tolerance parameter determines
how TeX will handle the overfull \hbox.  The default value of
\tolerance is 200.  Setting \tolerance to 1000 suppresses overfull
\hbox warnings and the printing of slugs.

3.4.  Page layout.

In addition to the left margin and line length dimensions that are
described in the previous section, TeX also lets you specify top and
bottom margins, and vertical spacing.

Like the \hsize and \hoffset dimensions described in the previous
section, TeX also provides the \vsize and \voffset commands.  The
default for \vsize is 8.9 in., and \voffset defaults to 0.

Normally, teTeX places the beginning of the first line of text 1 in.
below the top of the paper and 1 in. from the left edge.  You can
start the text closer to the top of the page with the command:

\voffset=-0.5in

If you want to add vertical space in a document, the commands
\smallskip, \medskip, and \bigskip will add approximately 3, 6, and 12
points of blank vertical space.  These measurements are approximate;
TeX will adjust them by as much as 1 pt. so the page is filled
correctly.

paragraphs on a page.  It is infinitely stretchable, so it will add
vertical space to fill as much of the rest of the page as possible.
If you want to specify a dimension, use \vskip as in:

\vskip 10pt

The commands \hss and \vss are similar to \hfil and \vfill, but they
provide dimensions that are infinitely shrinkable as well as
infinitely stretchable.

The \vskip and \vfill commands produce flexible lengths.  They do not
add space where no text exists; for example, at the top of a page.
Use \vglue if you want to add an absolute space.

TeX fills the \vsize dimension with as much text as possible before it
starts a new page.  To force a page break, use the \vfill \eject
sequence.  If \vfill is not used, the text before the \break will be
spaced to fill the page.

If you want TeX to be more flexible about its vertical page sizing,
place the \raggedbottom command in your document.  TeX will then
adjust the bottom margin of each page slightly to make vertical
spacing more consistent.

3.5.  Page numbers, headers, and footers.

teTeX by default places the page number at the bottom center of the
page.  If you want to change the location and style of the page
number, you can specify alternate headers and footers by changing
definitions of \headline and \footline.  The default value for
\footline contains the \folio command, which prints the page number.
The default value for \headline is \hfil, so a blank line is printed.

The \pageno command is a synonym for TeX's internal page counter.  You
can change the page number by changing the value of \pageno.  If
\pageno is negative, the numbers are printed as Roman numerals.

\pageno=10
\pageno=-1

The command \nopagenumbers is shorthand for:

\footline={\hfil}

The default footline also contains the font command \tenrm, which sets
the page number's font to 10-point Roman.  If you want to print the
page number in 12-point Roman, for example, you would first define a
12-point Roman font, and use that in the definition of \footline.
Font commands are discussed in Section Font commands''.

\font\twelvrm=cmr12
\footline={\hss\twelvrm\folio\hss}

You can put a rule, a horizontal line, at the top of each page by

To specify different headers for even and odd pages use the
\ifoddcommand, which has the form:

\ifodd[condition][true-action]\else[false-action

pages would be:

The \ifodd statement uses the first argument if the page number is
odd, and the second argument otherwise.

3.6.  Titles and macros.

TeX provides only the \beginsection macro for section headings.  It
leaves a space above its argument, prints the text of the heading in
bold type, adds a \smallskip after the text of the heading, and starts
the next paragraph with no indent.

The LaTeX chapter and section commands described below add section
numbering, and will print the section names and numbers in the page

In plain TeX, you must write these functions yourself.  The \def
command allows you to define new commands.  Suppose you want to print
a chapter title.  First you define the font that you want to use.  A
large, sans serif font for chapter titles would be defined like this:

\font\chapterfontsans=cmss12 scaled \magstep 4

You can use the \chapterfontsans command anywhere you want to switch
to this font, which is approximately 24 points in height.  However, in
this example, it will be used primarily in the command \chaptertitle­
sans.  Here is its definition:

\def\chaptertitlesans#1{\hbox{}\bigskip\bigskip
\noindent{\leftline{\chapterfontsans#1}}
\par\bigskip\bigskip\noindent}

The first line, \hbox{}\bigskip, anchors a 12-point space at the top
of the page by placing an empty \hbox{} there.  The line with the
chapter title is not indented, nor is the paragraph which immediately
follows it.  If you place a blank line between the \sschaptertitle
macro and the next paragraph, the final \noindent applies to the blank
line, not the text of the following paragraph.  To format correctly,
use the \sschaptertitle as in this example:

The #1 statement in the definition is replaced by the first argument
to \chaptertitlesans; that is, the title of the chapter.  Parameters
TeX definitions are declared with #1, #2, #3, and so on.  An example
usage of \chaptertitlesans would be:

\chaptertitlesans{Chapter 1}
This is the starting text of the first paragraph of the chapter.
The paragraph will not be indented.  The chapter's title is
"Chapter 1."

4.  LaTeX commands.

4.1.  Document structure.

Documents formatted for LaTeX have a few more rules, but with complex
documents, LaTeX can greatly simplify the formatting process.

Essentially, LaTeX is a document markup language which tries to
separate the output style from the document's logical content.  For
example, formatting a section heading with TeX would require
specifying 36 points of white space above the heading, then the
of white space after the heading.  By contrast, LaTeX has the
\section{} command, which does all of the work for you.  If you need
you can change the definition of \section{} instead of the text in the
document.  You can see where this would save hours of reformatting for
documents of more than a dozen pages in length.

All LaTeX documents have three sections: a preamble, the body text,
and a postamble.  These terms are standard jargon and are widely used
by TeXperts.

The preamble, at a minimum, specifies the type of document to be
produced---the document class---and a statement which signals the
beginning of the document's body text.  For example:

\documentclass{article}
\begin{document}

The document's postamble is usually very simple.  Except in special­
ized cases, it contains only the statement:

\end{document}

Note the \begin{document} and \end{document} pairing.  In LaTeX, this
is called an environment.  All text must appear within an environment,
and many commands are effective only in the environments in which
they're called.  The document environment is the only instance where
LaTeX enforces this convention, however.  That is, it's the only envi­
ronment that is required in a document.  (An exception is letter
class, which also requires you to declare \begin{letter} and
\end{letter}.  See the section Letters''.)  However, many formatting
features are specified as environments.  They're described in the fol­
lowing sections.

The document classes can be called with arguments.  For example,
instead of the default, 10-point type used as the base point size, as
in the previous example, we could have specified

\documentclass[12pt]{article}

to produce the document using 12 points as the base point size.  The
document class, article, makes the necessary adjustments.

There are a few document classes which are commonly used.  They're
described below.  The report class is similar to article class, but
produces a title page and starts each section on a new page.  The
letter class includes special definitions for addresses, salutations,
and closings, a few of which are described below.

You can include canned LaTeX code, commonly known as a package, with
the \usepackage{} command.

\usepackage{fancyhdr}

The command above would include the LaTeX style file fancyhdr.sty from
one of the TEXINPUTS directories, which you and teTeX specified during
installation and setup processes.

\documentclass{article}
\usepackage{fancyhdr}
\begin{document}

Note that the \usepackage{} declarations are given before the
\begin{document} statement; that is, in the document preamble.

fancyhdr.sty extends the \pagestyle{} command so that you can create
custom headers and footers.  Most LaTeX document classes provide
headers and footers of the following standard page styles:

\pagestyle{plain}       % default pages style -- page number centered at
% the bottom of the page.
\pagestyle{empty}       % no headers or footers
\pagestyle{headings}    % print section number and page number at the
% top of the page.

Everything on a line to the right of the percent sign is a comment.

The \pagestyle{} command doesn't take effect until the following page.
To change the headers and footers on the current page, use the command

\thispagestyle{the_pagestyle}

4.2.  Characters and type styles.

Character styles are partially a function of the fonts specified in
the document.  However, bold and italic character emphasis should be
available for every font present on the system.  Underlining, too, can
be used, though its formatting presents special problems.  See section
LaTeX extension packages and other resources'', below.

You can specify text to be emphasized in several ways.  The most
portable is the \em command.  All text within its scope is italicized
by default.  For example:

This word will be {\em emphasized.}

If you have italicized text that runs into text which is not itali­
cized, you can specify an italic correction factor to be used.  The
command for this is \/; that is, a backslash and a forward slash.

This example {\em will\/} print correctly.

This example will {\em not} print correctly.

Slightly less portable, but still acceptable in situations where
they're used singly, are the commands \it, \bf, and \tt, which specify
that the characters within their scope be printed using italic, bold,
and monospaced (teletype) typefaces, respectively.

{\tt This text will be printed monospaced,}
{\it this text will be italic,} and
{\bf this text will be bold\dots} all in one paragraph.

The command \dots prints a series of three periods for ellipses, which
will not break across a line.

The most recent version of LaTeX, which is what you have, includes
commands which account for instances where one emphasis command would
supersede another.

This is {\it not {\bf bold italic!}}

What happens is that teTeX formats the text with the italic typeface
until it encounters the \bf command, at which point it switches to
boldface type.

To get around this, the NFSS scheme of selecting font shapes requires
three parameters for each typeface: shape, series, and family.  Not
all font sets will include all of these styles.  LaTeX will print a
warning, however, if it needs to substitute another font.

You can specify the following font shapes:

\textup{text}          % upright shape (the default)
\textit{text}          % italic
\textsl{text}          % slanted
\textsc{text}          % small caps

These are the two series that most fonts have:

\textmd{text}          % medium series (the default)
\textbf{text}          % boldface series.

There are generally three families of type available.

\textrm{text}          % Roman (the default)
\textsf{text}          % sans serif
\texttt{text}          % typewriter (monospaced, Courier-like)

Setting font styles using these parameters, you can combine effects.

\texttt{\textit{This example likely will result in a font
substitution, because many fonts don't include a typewriter italic
typeface.}}

The font family defaults to Computer Modern, which is a bit-mapped
font.  Other font families are usually Postscript-format Type 1 fonts.
See section Using PostScript fonts'' for details on how to specify
them.

There are also many forms of accents and special characters which are
available for typesetting.  This is only a few of them.  (Try
typesetting these on your own printer.)

\'{o}  \{e}  \^{o}  \"{u}        \={o}  \c{c}  ? !

Finally, there are characters which are used as meta- or escape char­
acters in TeX and LaTeX.  One of them, the dollar sign, is mentioned
above.  The complete set of meta characters, which need to be escaped
with a backslash to be used literally, is:

# $% & _ { } There are also different alphabets available, like Greek and Cyrillic. LaTeX provides many facilities for setting non-English text, which are covered by some of the other references mentioned here 4.3. Margins and line spacing. Changing margins in a TeX or LaTeX document is not a straightforward task. A lot depends on the relative indent of the text you're trying to adjust the margin for. The placement of the margin-changing command is also significant. For document-wide changes to LaTeX documents, the \evensidemargin and \oddsidemargin commands are available. They affect the left-hand margins of the even-numbered and odd-numbered pages, respectively. For example, \evensidemargin=1in \oddsidemargin=1in adds on inch to the left-hand margin of the even and odd pages in addition to the standard one-inch, left-hand margin. These commands affect the entire document and will shift the entire body of the text right and left across a page, regardless of any local indent, so they're safe to use with LaTeX environments like verse and list. Below is a set of margin-changing macros which I wrote. They have a different effect than the commands mentioned above. Because they use plain TeX commands, they're not guaranteed to honor the margins of any LaTeX environments which may be in effect, but you can place them anywhere in a document and change the margins from that point on. %% margins.sty -- v. 0.1 by Robert Kiesling %% Copies of this code may be freely distributed in verbatim form. %% %% Some elementary plain TeX margin-changing commands. Lengths are %% in inches: %% \leftmargin{1} %% sets the document's left margin in 1 inch. %% \leftindent{1} %% sets the following paragraphs' indent in %% 1 inch. %% \rightindent{1} %% sets the following paragraphs' right margins %% %% in 1 inch. %% \llength{3} %% sets the following lines' lengths to 3 inches. %% \message{Margins macros...} \def\lmargin#1{\hoffset = #1 in} \def\lindent#1{\leftskip = #1 in} \def\rindent#1{\rightskip = #1 in} \def\llength#1{\hsize = #1 in} %% %% (End of margins macros.} Place this code in a file called margins.sty in your local$TEXINPUTS
directory.  The commands are explained in the commented section of the
file.  To include them in a document, use the command

\usepackage{margins}

in the document preamble.

While we're on the subject, if you don't want the right margin to be
justified, which is the default, you can tell LaTeX to use ragged
right margins by giving the command:

\raggedright

Setting line spacing also has its complexities.

The baselineskip measurement is the distance between lines of text.
It is given as an absolute measurement.  For example,

\baselineskip=24pt

or even better:

\setlength{\baselineskip}{24pt}

The difference between the two forms is that setlength will respect
any scoping rules that may be in effect when you use the command.

The problem with using baselineskip is that it also affects the
distance between section headings, footnotes, and the like.  You need
to take care that baselineskip is correct for whatever text elements
you're formatting.  There are, however, LaTeX macro packages, like
LaTeX extension packages and other resources''.

4.4.  Document classes.

LaTeX provides document classes which provide standardized formats for
documents.  They provide environments to format lists, quotations,
footnotes, and other text elements.  Commonly used document classes
are covered in the following sections.

4.4.1.  Articles and reports.

As mentioned above, the article class and the report class are
similar.  The main differences are that the report class creates a
title page by default and begins each section on a new page.  Mostly,
though, the two document classes are similar.

To create titles, abstracts, and bylines in these document classes,
you can type, for example,

\title{The Breeding Habits of Cacti}
\author{John Q. Public}
\abstract{Description of how common desert cacti search
for appropriate watering holes to perform their breeding
rituals.}

in the document preamble.  Then, the command

\maketitle

given at the start of the text, will generate either a title page in
the report class, or the title and abstract at the top of the first
page, in the article class.

Sections can be defined with commands that include the following:

\section
\subsection
\subsubsection

These commands will produce the standard, numbered sections used in
technical documents.  For unnumbered sections, use

\section*
\subsection*
\subsubsection*

and so on.

LaTeX provides many environments for formatting displayed material.
You can include quoted text with the quotation environment.

\begin{quotation}
Start of paragraph to be quoted...

... end of paragraph.
\end{quotation}

For shorter quotes, you can use the quote environment.

To format verse, use the verse environment.

\begin{verse}
Because I could not stop for death\\
He kindly stopped for me
\end{verse}

Notice that you must use the double backslashes to break lines in the
correct places.  Otherwise, LaTeX fills the lines in a verse environ­
ment, just like any other environment.

Lists come in several flavors.  To format a bulleted list, the list
environment is used:

\begin{list}
\item
This is the first item of the list.
\item
This is the second item of the list...
\item
... and so on.
\end{list}

A numbered list uses the enumerate environment:

\begin{enumerate}
\item
Item No. 1.
\item
Item No. 2.
\item
\dots
\end{enumerate}

A descriptive list uses the description environment.

\begin{description}
\item{Oven} Dirty, needs new burner.
\item{Refrigerator}  Dirty.  Sorry.
\item{Sink and drainboard}  Stained, drippy, cold water faucet.
\end{description}

4.4.2.  Letters.

The letter class uses special definitions to format business letters.

The letter environment takes one argument, the address of the letter's
preamble, defines the return address.  The signature command defines
the sender's name as it appears after the closing.

The LaTeX source of a simple business letter might look like this.

\documentclass[12pt]{letter}
\signature{John Q. Public}
\address{123 Main St.\\Los Angeles, CA.  96005\\Tel: 123/456-7890}
\begin{document}
\begin{letter}{ACME Brick Co.\\100 Ash St.\\San Diego, CA 96403}

With regard to one of your bricks that I found on my living room
carpet surrounded by shards of my broken front window...

(Remainder of the body of the letter.)

\closing{Sincerely,}

\end{letter}
\end{document}

Note that the addresses include double backslashes, which specify
where the line breaks should occur.

5.  LaTeX extension packages and other resources.

We mentioned above that using underlining as a form of text emphasis
presents special problems.  Actually, TeX has no problem underlining
text, because it is a convention of mathematical typesetting.  In
LaTeX, you can underline words with the command:

\underline{text to be underlined}

The problem is that underlining will not break across lines, and, in
some circumstances, underlining can be uneven.  However, there is a
mode of text emphasis.  It's called ulem.sty, and is one of the many
contributed LaTeX packages that are freely available via the Internet.

To use ulem.sty, include the command:

\usepackage{ulem}

in the document preamble.

The packages which are available for LaTeX include:

ifthen
Include conditional statements in your documents.

initials
Defines a font for initial dropped capitals.

sanskrit
Font and preprocessor for producing documents in Sanskrit.

recipe
A LaTeX2e class to typeset recipes.

refman
Variant report and article styles.

To make the path given in the Catalogue into a fully-qualified URL,
concatenate the path to the host name URL and top-level path of the
CTAN archive you wish to contact.  For example, the top-level CTAN
directory of the site ftp.tex.ac.uk is ctan/tex-archive.  The complete
URL of the directory of the refman package would be:

ftp://ftp.tex.ac.uk/ctan/tex-archive/   +
macros/latex/contrib/supported/refman   =

ftp://ftp.tex.ac.uk/ctan/tex-archive/macros/latex/contrib/supported/refman/

Some packages have more than one file, so only the path to the pack­
age's directory is given.

When you have the URL in hand, you can retrieve the package from one
of the CTAN archive sites listed in section Appendix A''.  You can
FILES.byname, in the archive's top-level directory.  You can also
search the archive on line for a keyword with the ftp command

quote site index <keyword>

6.  Mixing text and graphics with dvips .

In general, this section applies to any TeX or LaTeX document which
mixes text and graphics.  teTeX, like most other TeX distributions, is
configured to request Computer Modern fonts by default.  When printing
documents with Type 1 scalable fonts or graphics, font and graphics
imaging is the job of dvips. dvips can use either Computer Modern bit
mapped fonts or Type 1 scalable fonts, or any combination of the two.
First, let's concentrate on printing and previewing some graphics.

You will probably want to follow this procedure any time a LaTeX
source document has the statement

\includepackage{graphics}

in the document preamble.  This statement tells LaTeX to include the
text of the graphics.sty package in the source document.  There are
other commands to perform graphics operations, and the statements in
plain-TeX documents may not clue you in whether you need to use dvips.
The difference will be apparent in the output, though, when the docu­
ment is printed with missing figures and other graphics.

So, for now, we'll concentrate on printing documents which use the
LaTeX graphics.sty package.  You might want to take a look at the
original TeX input.  It isn't included in the teTeX distribution, but
it is available at

~CTAN/macros/latex/packages/graphics/grfguide.tex.

What the teTeX distribution does include is the .dvi output file, and
it is already TeXed for you.  There is a reason for this, and it has
to do with the necessity of including Type 1 fonts in the output in
order for the document to print properly.  If you want to LaTeX
grfguide.tex, see the next section.  For now, however, we'll work on
getting usable output using dvips.

The file grfguide.dvi is located in the directory

texmf/doc/latex/graphics

The first step in outputting grfguide.dvi is to translate it to
Postscript.  The program dvips is used for this.  It does just exactly
what its name implies.  There are many options available for invoking
dvips, but the simplest (nearly) form is

dvips -f -r <grfguide.dvi >grfguide.ps

The -f command switch tells dvips to operate as a filter, reading from
standard input and writing to standard output.  dvips output can be
configured so its output defaults to lpr.

If you can print Postscript directly to your printer via lpr, you can
simply type

dvips -r grfguide.dvi

The -r option tells dvips to output the pages in reverse order so they
stack correctly when they exit a printer.  Use it or not, as appropri­

Depending on whether you still have the fonts that dvilj2 generated
from the last document, dvips and metafont may or may not need to
create new fonts needed by grfguide.dvi.  Eventually, though, dvips
will output a list of the pages translated to Postscript, and you will
device you have available.

If you're lucky (and rich), then you have a Postscript-capable printer
already and will be able to print grfguide.ps directly.  You can
either spool the output to the printer using lpr.  If for some reason
your printer software doesn't work right with Postscript files, you
can, in a pinch, simply dump the file to printer, with

cat grfguide.ps >/dev/lp0

or whichever port your printer is attached to, though this is not rec­
ommended for everyday use.

If you want or need to invoke Ghostscript manually, this is the
standard procedure for its operation.  The first thing you want to do
is invoke Ghostscript to view its command line arguments, like this:

gs -help | less

You'll see a list of supported output devices and sundry other com­
mands.  Pick the output device which most nearly matches your printer.
I generally produce black-and-white text and use the cdjmono driver,
which drives a color Deskjet in monochrome (black and white) mode.

The command line I would use is:

gs -dNOPAUSE -sDEVICE=cdjmono -sOutputFile=/tmp/gs.out grfguide.ps -c quit

This will produce my HP-compatible output in the /tmp directory.  It's
a good idea to use a directory like /tmp, because gs can be particular
about access permissions, and you can't (and shouldn't) always count
on being logged in as root to perform these steps.  Now you can print
the file:

lpr /tmp/gs.out

Obviously, this can all go into a shell script.  On my system, I have
two simple scripts written, pv and pr, which simply outputs the
Postscript file either to the display or the printer.  Screen preview­
ing is possible without X, but it's far from ideal.  So, it's defi­
nitely worth the effort to install XFree86 to view the output on the
screen..

The order of commands in a gs command line is significant, because
some of the options tell Ghostscript to look for pieces of Postscript
code from its library.

The important thing to remember is that grfguide.dvi makes requests
for both Computer Modern bit mapped and Type 1 scaled fonts.  If you
can mix scalable and bit mapped fonts in a document, you're well on
the way to becoming a TeXpert.

6.1.  What if my printer isn't supported?

The teTeX distribution comes with only a limited selection of DVI
output drivers: dvips, drivers for Hewlett Packard LaserJets, and
nothing else.  You have two options if you have a printer which isn't
LaserJet-compatible: You can use dvips and Ghostscript, which I would
recommend anyway, for reasons already mentioned, or you can
investigate other dviware sources.

A limited number of DVI drivers have been ported to Linux and are
available as pre-built binaries.  They are located in the Linux
archives at ftp://sunsite.unc.edu/pub/Linux/apps/tex/dvi/.

The master dviware libraries are maintained at the University of Utah
archives.  If you can't find a DVI driver there that supports your
printer, chances are that it doesn't exist.  You can also write your
own DVI driver using the templates available there.  The library's URL
is ftp://ftp.math.utah.edu/pub/tex/dvi/.

7.  Using Postscript fonts.

It used to be that public domain, Type 1 fonts were much poorer
quality than Computer Modern bit mapped fonts.  This situation has
improved in the last several years, though, but matching the fonts is
up to you.  Having several different font systems on one machine can
seem redundant and an unnecessary waste of disk space.  And the
Computer Modern fonts can seem, well, a little too formal to be
suitable for everyday use.  It reminds me sometimes of bringing out
the good China to feed the dog.  At least you don't need to spend a
bundle on professional quality fonts any longer.

One of the major improvements of LaTeX2e over its predecessor was the
inclusion of the New Font Selection Scheme.  (It's now called PSNFSS.)
Formerly, TeX authors would specify fonts with commands like

\font=bodyroman = cmr10 scaled \magstep 1

which provides precision but requires the skills of a type designer
and mathematician to make good use of.  Also, it's not very portable.
If another system didn't have the font cmr10 (this is TeX nomenclature
for Computer Modern Roman, 10 point, with the default medium stroke
weight), somebody would have to re-code the fonts specifications for
the entire document.  PSNFSS, however, allows you specify fonts by
family (Computer Modern, URW Nimbus, Helvetica, Utopia, and so forth),
weight (light, medium, bold), orientation (upright or oblique), face
(Roman, Italic), and base point size.  (See the section Characters
and type styles'' for a description of the commands to specify
typefaces.)  Many fonts are packaged as families.  For example, a
Roman-type font may come packaged with a sans serif font, like
Helvetica, and a monospaced font, like Courier.  You, as the author of
a LaTeX document, can specify an entire font family with one command.

There are, as I said, several high-quality font sets available in the
public domain.  One of them is Adobe Utopia.  Another is Bitstream
Charter.  Both are commercial quality fonts which have been donated to
the public domain.

These happen to be two of my favorites.  If you look around one of the
CTAN sites, you will find these and other fonts archived there. There
are enough fonts around that you'll be able to design documents the
way you want them to look, and not just English text, either.  TeX was
originally designed for mathematical typesetting, so there is a full
range of mathematical fonts available, as well as Cyrillic, Greek,
Kana, and other alphabets too numerous to mention.

The important thing to look for is files which have either the .pfa or
.pfb extension.  They indicate that these are the scalable fonts
themselves, not simply the metrics files.  Type 1 fonts use .pfm
metric files, as opposed to the .tfm metric files which bit mapped
fonts use.  The two font sets I mentioned above are included in teTeX
distributions, as well as separately.

What I said above, concerning the ease of font selection under PSNFSS,
is true in this instance.  If we want to use the Charter fonts in our
document instead of Computer Modern bit mapped, all that is necessary
is include the LaTeX statement

\renewcommand{\familydefault}{bch}

in the document preamble, where bch'' is the common designation for
Bitstream Charter.  The Charter fonts reside in the directory

/usr/lib/teTeX/texmf/fonts/type1/bitstrea/charter

There you'll see the .pfb files of the Charter fonts: bchb8a.pfb for
Charter Bold, bchr8a.pfb for Charter Roman, bchbi8a.pfb for Charter
Bold Italic.  The 8a'' in the font names indicates the character
encoding.  At this point you shouldn't need to worry much about them,
because the encodings mostly differ for 8-bit characters, which have
numeric values above 128 decimal.  They mostly define accents and non-
English characters.  The Type 1 font encodings generally work well for
Western alphabets because they conform to the ISO 8859 standards for
international character sets, so this is an added benefit of using
them.

To typeset a document which has Charter fonts selected, you would give
the command

pslatex document.tex

pslatex is a variant of teTeX's standard latex command which defines
the directories where the Type 1 fonts are, as well as some additional
LaTeX code to load.  You'll see the notice screen for pslatex followed
by the status output of the TeX job itself.  In a moment, you'll have
a .dvi file which includes the Charter font requests.  You can then
print the file with dvips, and gs if necessary.

Installing a Type 1 font set is not difficult, as long as you follow a
few basic steps.  You should unpack the fonts in a subdirectory of the
/usr/lib/teTeX/texmf/fonts/type1 directory, where your other Type 1
fonts are located, and then run texhash to let the directory search
routines know that the fonts have been added.  Then you need to add
the font descriptions to the file psfonts.map so dvips knows they're
on the system.  The format of the psfonts.map file is covered in a
couple different places in the references mentioned above.  Again,
remember to run the texhash program to update the teTeX directory
database.

It is definitely an advantage to use the X Windows System with
teTeX--- XFree86 under Linux---because it allows for superior document
previewing.  It's not required, but in general, anything that allows
for easier screen previewing is going to benefit your work, in terms
of the quality of the output.  However, there is a tradeoff with speed
of editing, which is much quicker on character-mode displays.

8.  Appendix A: CTAN site list.

This is the text of the file CTAN.sites, which is available in the
top-level directory of each CTAN archive or mirror site.

In order to reduce network load, it is recommended that you use the
Comprehensive TeX Archive Network (CTAN) host which is located in the
closest network proximity to your site.  Alternatively, you may wish to
obtain a copy of the CTAN via CD-ROM (see help/CTAN.cdrom for details).

9.  Appendix B: Installing the CTAN teTeX distribution.

The generic, teTeX distribution isn't any harder to install than the
Linux packages.  See section Generic CTAN distribution'', below.

You should consider installing the generic teTeX distribution from the
CTAN archives if:

·  Your system isn't based on one of the standard Linux distributions.

·  You don't have root privileges on your system.

·  You want or need to have the very latest version of teTeX, or
LaTeX.

·  You don't have enough disk space available for a full installation.

·  You want to install teTeX somewhere instead of the /usr file
system.

·  You would like to share your teTeX installation with other UNIX
variants or platforms on a network.  In this case, you should
strongly consider installing from the source distribution.  See
section Installing the source distribution'', below.

·  You want the latest versions of teTeX's public domain Type 1 fonts,
which are significantly better than the fonts included in earlier
releases.

A complete installation of the binary distribution requires 40-50 Mb
of disk space, and building the distribution from the source code
takes about 75 Mb, so you should make sure that the disk space is
available before you start.  You don't need to have the GCC compiler
or the X Windows System installed (although X certainly helps because
it is much easier to preview documents on-screen).  All you need is an
editor that is capable of producing plain ASCII, text (see section 2).
What could be simpler?

You can retrieve the files from one of the CTAN archives listed in
section Appendix A''.  In the examples below, the files were

9.1.  Installing the binary distribution.

9.1.1.  Minimal installation.

First, FTP to ftp.tex.ac.uk and cd to the directory

ctan/tex-archive/systems/unix/teTeX/distrib/

Retrieve the files

INSTALL.bin
install.sh

and place them in the top-level directory where you want to install
teTeX, for example, /var/teTeX if you plan to install teTeX in the
/var file system.

Print out the INSTALL.bin file.  Keep this file handy, because it
describes how to install a minimal teTeX installation.  The minimal
installation requires only 10-15 MB of disk space, but it is
recommended that you install the complete teTeX package if at all
possible.  For a minimum installation, you'll need the files

ctan/tex-archive/systems/unix/teTeX/distrib/base/latex-base.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/base/tetex-base.tar.gz

You'll also need one of two archives which contain the executable
teTeX programs.  Retrieve the archive file

ctan/tex-archive/systems/unix/teTeX/distrib/binaries/i386-linux.tar.gz

if your system uses the Linux ELF shared libraries, ld.so of at least
version 1.73, and clibs of at least version 5.09.  If it doesn't,
retrieve the archive

ctan/tex-archive/systems/unix/teTeX/distrib/binaries/i386-linuxaout.tar.gz

which is compiled for systems that use the older, a.out-format static
libraries.

Then, following the instructions in the file INSTALL.bin, execute the
command

sh ./install.sh

while in the top-level teTeX installation directory. (Make sure that
the teTeX archives are located there, too.)  After a few moments, the
installation program will warn you that you are missing some of the
teTeX packages.  However, if you're planning only a minimal teTeX
installation, you should ignore the warnings and proceed.  To config­
ure the basic teTeX system, see section Base system configuration'',
below.

To install the remaining packages, see the next section.

9.1.2.  Complete installation.

To perform a complete teTeX installation, retrieve the archive files
listed in the previous section, as well as the following files:

ctan/tex-archive/systems/unix/teTeX/distrib/doc/ams-doc.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/doc/bibtex-doc.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/doc/eplain-doc.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/doc/fonts-doc.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/doc/general-doc.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/doc/generic-doc.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/doc/latex-doc.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/doc/makeindex-doc.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/doc/metapost-doc.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/doc/programs-doc.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/fonts/ams-fonts.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/fonts/dc-fonts.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/fonts/ec-fonts.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/fonts/misc-fonts.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/fonts/postscript-fonts.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/fonts/sauter-fonts.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/goodies/amstex.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/goodies/bibtex.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/goodies/eplain.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/goodies/latex-extra.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/goodies/metapost.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/goodies/pictex.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/goodies/pstricks.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/goodies/texdraw.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/goodies/xypic.tar.gz

All of these files should be placed in the top-level directory where
you want teTeX to reside.  As with the minimal installation, execute
the command

sh ./install.sh

9.2.  Base system configuration.

The install.sh script, after determining which teTeX archive series
are present, will present you with a menu of options.  The only
setting you need to make at this point is to set the top-level
directory where you want teTeX installed, by selecting the D''
option.  You must, of course, choose a directory in whose parent
directory you have write permissions.  For example, if you are
installing teTeX in your home directory, you would specify the teTeX
installation directory as

/home/john.q.public/teTeX

and, after returning to the main menu, select I'' to proceed with
the installation.  Note that the directory must not exist already: the
install.sh script must be able to create it.

An option which you should consider enabling, is setting an
alternative directory for generated fonts.  Even if you plan to use
only Postscript-format, Type 1 scalable fonts, occasionally you'll
process a file that requires the Computer Modern fonts.  Enabling this
option requires that you enter the directory to use.  You must have
write permissions for the parent directory.  Following the example
above, you could specify

/home/john.q.public/texfonts

or, if you want the generated fonts to be accessible by all users on
the system, specify a directory like
/var/texfonts

I would recommend that you not, however, use the default /var/tmp/tex­
fonts directory for this option, because the generated fonts could be
deleted after the next reboot, and the fonts will need to be generated
again the next time they're needed.

After you've selected the option I'', and install.sh has installed
the archives, set various permissions, and generated its links and
format files, the program will exit with a message telling you to add
the teTeX binary directory to your $PATH environment variable, and the directories where the man pages and info files reside to your$MANPATH
and $INFOPATH environment variables. For example, add the statements export PATH=$PATH:"/home/john.q.public/teTeX/bin"
export MANPATH=$MANPATH":/home/john.q.public/teTeX/man" export INFOPATH$=INFOPATH":/home/john.q.public/teTeX/info"

to your ~/.bash_profile if you use bash as your shell, or to your
~/.profile if you use another shell for logins.

Log out, and then log in again, so the environment variables are
registered.  Then, run the command

texconfig confall

to insure that the installation is correct.

Next, you can configure teTeX for you specific hardware.  See section
Post-installation configuration details'', below.

9.3.  Installing the CTAN source distribution.

To install teTeX V. 0.4 from the source code, ftp to a CTAN site like
ftp://ftp.tex.ac.uk and retrieve the files

ctan/tex-archive/systems/unix/teTeX/distrib/INSTALL.src
ctan/tex-archive/systems/unix/teTeX/distrib/sources/teTeX-lib-0.4pl8.tar.gz
ctan/tex-archive/systems/unix/teTeX/distrib/sources/teTeX-src-0.4pl7.tar.gz

Read over the instructions in INSTALL.src, then su to root and unpack
the files in a directory for which you have read-write-execute
permissions.

Remember to use the p argument to tar, and also remember to unset the
noclobber option of bash.  You can do this with the counterintuitive
command

set +o noclobber

Note that the argument +o to set unsets a variable, just exactly back­
wards from what you might expect.

The file teTeX-lib-0.4pl8.tar.gz will create the directory ./teTeX.
The file teTeX-src-0.4pl7.tar.gz will create the directory teTeX-
src-0.4 Print out the file INSTALL.src and keep it nearby for the
following steps. cd to the ./teTeX-src-0.4 directory, and, per the
instructions in the INSTALL.src file, edit ./Makefile.  You need to
set the TETEXDIR variable to the absolute path of the parent teTeX
directory.  This will be the subdirectory teTeX of the directory where
you unpacked the source and library archives.  For example, if you
unpacked the archives in your home directory, you would set TETEXDIR
to

/home/john.q.public/teTeX

The rest of the Makefile options are pretty generic.  With GCC version
2.7.2 and later, you should not need to make any further adjustments
unless you have a non-standard compiler and library setup, or want the
compiler to perform some further optimizations, or for some other rea­
son.  Check that the USE_DIALOG, USE_NCURSES, and HAVE_NCURSES vari­
ables are set correctly for your system, because the dialog program
needs the ncurses library to be installed.  A ncurses library is
included in the source distribution, so the default values in the
Makefile should work fine.  If you can't get ncurses to compile or
link, texconfig can also be run from the command line.

If you've done everything correctly up to this point, you should be
able to type make world in the top-level source directory, and relax
until the teTeX executables are built.  This can take a few hours.

After the build has completed, set the environment variables $PATH,$MANPATH, and $INFOPATH to include the teTeX directories. The statements which would be added to the file ~/.bash_profile, in the example, above, would be export PATH=$PATH":/home/john.q.public/teTeX/bin/i386-linux"
export MANPATH=$MANPATH":/home/john.q.public/teTeX/man" export INFOPATH=$INFOPATH":/home/john.q.public/teTeX/info"

The $PATH variable is different in the source distribution than in the binary distribution. Note that here the path to the binaries is teTeX/bin/i386-linux instead of simply teTeX/bin as in the binary dis­ tribution. At this point you can run texconfig confall to ensure that the paths have been set correctly, and then proceed to configure teTeX as in the binary distribution. See the section Post-installation configuration details'', below. 9.4. Post-installation configuration details. The first thing you want to do is look at Thomas Esser's README file. It contains a lot of hints on how to configure teTeX for your output device (i.e., printer). The README file is located in the directory /usr/lib/teTeX/texmf/doc/tetex Read the file over with the command (the path in the following exam­ ples is that of the Slackware distribution): less /usr/lib/teTeX/texmf/doc/tetex/README or, print it out with the command cat /usr/lib/teTeX/texmf/doc/tetex/README >/dev/lp0 assuming that your printer is connected to /dev/lp0. Substitute the device driver file that your printer is connected to, as appropriate. Or, better still, print it using the lpr command: lpr /usr/lib/teTeX/texmf/doc/tetex/README You should have installed the printer daemon that is included with your distribution of Linux. If not, do that now, per the instructions that come with the package. Print out the teTeX-FAQ. Keep the FAQ handy because it contains useful hints for configuring teTeX's output drivers for your printer. We'll get to that in a moment. In more recent releases of teTeX, the teTeX- FAQ is viewable via the texconfig utility. Next, you want to define a directory to store your own TeX format files. teTeX searches the directories listed by the$TEXINPUTS
environment variable for local TeX input files:

export TEXINPUTS=".:~/texinputs:"

to the system-wide /etc/profile file.  Individual users can set their
own local $TEXINPUTS directory, by adding the line in their ~/.profile or ~/.bash_profile if bash is the default shell. The$TEXINPUTS envi­
ronment variable tells teTeX to look for users' individual TeX style
files in the ~/texinputs directories under each user's home directory.
It is critical that a colon appear before and after this directory.
teTeX is going to append its own directory searches to your own.  You
want to have teTeX search the local format files first, so it uses the
local versions of any of the standard files you have edited.

Add the /usr/lib/teTeX/bin directory to the system-wide path if you're
installing teTeX as root.  Again, if you're installing a personal copy
of teTeX, add the directory where the teTeX binaries are located to
the front your $PATH with the following line in your ~/.profile or ~/.bash_profile: export PATH="~/tetex/bin:"$PATH

Now, log in as root and run texconfig per the instructions in the
teTeX-FAQ and choose the printer that is attached to your system.
Make sure that you configure teTeX for both the correct printer and
printer resolution.

Finally, run the texhash program.  This ensures that teTeX's internal
database is up to date.  The database is actually a ls-lR file.  You
must run texhash every time you change the system configuration, or
teTeX will not be able to locate your changes.

10.  Appendix C: Distribution and Copyright.

10.1.  Distribution.

teTeX is free software; this means everyone is free to use the
software and free to redistribute it on certain conditions.  The
package is not in the public domain.  It is copyrighted and there are
restrictions on its distribution, but these restrictions are designed
to permit everything that a good cooperating citizen would want to do.
What is not allowed is to try to prevent others from further sharing
any version of free software that they might get from you.  The
precise conditions are found in the GNU General Public License that
comes with many of the software packages and also appears following
this section.

One way to get a copy of the package is from someone else who has it.
You need not ask for our permission to do so, or tell any one else;
just copy it.  If you have access to the Internet, you can get the
latest distribution versions by anonymous FTP.  See the chapter
Sources'' for more information.

You may also receive the software when you buy a computer.  Computer
manufacturers are free to distribute copies on the same terms that
apply to everyone else.  These terms require them to give you the full
sources, including whatever changes they may have made, and to permit
you to redistribute these packages received from them under the usual
terms of the General Public License.  In other words, the program must
be free for you when you get it, not just free for the manufacturer.

You can also order copies of GNU software from the Free Software
Foundation on CD-ROM.  This is a convenient and reliable way to get a
copy; it is also a good way to help fund our work.  (The Foundation
has always received most of its funds in this way.)  An order form is
included many distribution, and on our web site in
http://www.gnu.ai.mit.edu/order/order.html.  For further information,
write to

The income from distribution fees goes to support the foundation's
purpose: the development of new free software, and improvements to our
existing programs.

If you use GNU software at your workplace, please suggest that the
company make a donation.  If company policy is unsympathetic to the
idea of donating to charity, you might instead suggest ordering a CD-
ROM from the Foundation occasionally, or subscribing to periodic

Everyone is permitted to copy and distribute verbatim copies of this
license document, but changing it is not allowed.

Preamble.

The licenses for most software are designed to take away your freedom
to share and change it.  By contrast, the GNU General Public License
is intended to guarantee your freedom to share and change free
software---to make sure the software is free for all its users.  This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it.  (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.)  You can apply it to

When we speak of free software, we are referring to freedom, not
price.  Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.

To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if
you distribute copies of the software, or if you modify it.

For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have.  You must make sure that they, too, receive or can get the
source code.  And you must show them these terms so they know their
rights.

We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.

Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software.  If the software is modified by someone else and passed on,
we want its recipients to know that what they have is not the
original, so that any problems introduced by others will not reflect
on the original authors' reputations.

Finally, any free program is threatened constantly by software
patents.  We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary.  To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at
all.

The precise terms and conditions for copying, distribution and
modification follow.

TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

·  This License applies to any program or other work which contains a
notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License.  The Program''
below, refers to any such program or work, and a work based on
the Program'' means either the Program or any derivative work under
copyright law: that is to say, a work containing the Program or a
portion of it, either verbatim or with modifications and/or
translated into another language.  (Hereinafter, translation is
included without limitation in the term,modification.'')  Each
licensee is addressed as you.''

Activities other than copying, distribution and modification are
not covered by this License; they are outside its scope.  The act
of running the Program is not restricted, and the output from the
Program is covered only if its contents constitute a work based on
the Program (independent of having been made by running the
Program).  Whether that is true depends on what the Program does.

·  You may copy and distribute verbatim copies of the Program's source
code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any
warranty; and give any other recipients of the Program a copy of
this License along with the Program.

You may charge a fee for the physical act of transferring a copy,
and you may at your option offer warranty protection in exchange
for a fee.

·  You may modify your copy or copies of the Program or any portion of
it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:

1. You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.

2. You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.

3. If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a notice
that there is no warranty (or else, saying that you provide a
warranty) and that users may redistribute the program under these
conditions, and telling the user how to view a copy of this
License.  (Exception: if the Program itself is interactive but does
not normally print such an announcement, your work based on the
Program is not required to print an announcement.)

These requirements apply to the modified work as a whole.  If
identifiable sections of that work are not derived from the
Program, and can be reasonably considered independent and separate
works in themselves, then this License, and its terms, do not apply
to those sections when you distribute them as separate works.  But
when you distribute the same sections as part of a whole which is a
work based on the Program, the distribution of the whole must be on
extend to the entire whole, and thus to each and every part
regardless of who wrote it.

Thus, it is not the intent of this section to claim rights or
contest your rights to work written entirely by you; rather, the
intent is to exercise the right to control the distribution of
derivative or collective works based on the Program.

In addition, mere aggregation of another work not based on the
Program with the Program (or with a work based on the Program) on a
volume of a storage or distribution medium does not bring the other
work under the scope of this License.

·  You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms
of Sections 1 and 2 above provided that you also do one of the
following:

1. Accompany it with the complete corresponding machine-readable
1 and 2 above on a medium customarily used for software
interchange; or,

2. Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your cost
of physically performing source distribution, a complete machine-
readable copy of the corresponding source code, to be distributed
under the terms of Sections 1 and 2 above on a medium customarily
used for software interchange; or,

3. Accompany it with the information you received as to the offer
to distribute corresponding source code.  (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such an
offer, in accord with Subsection b above.)

The source code for a work means the preferred form of the work for
making modifications to it.  For an executable work, complete
source code means all the source code for all modules it contains,
plus any associated interface definition files, plus the scripts
used to control compilation and installation of the executable.
However, as a special exception, the source code distributed need
not include anything that is normally distributed (in either source
or binary form) with the major components (compiler, kernel, and so
on) of the operating system on which the executable runs, unless
that component itself accompanies the executable.

If distribution of executable or object code is made by offering
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.

·  You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License.  Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this
so long as such parties remain in full compliance.

·  You are not required to accept this License, since you have not
signed it.  However, nothing else grants you permission to modify
or distribute the Program or its derivative works.  These actions
are prohibited by law if you do not accept this License.
Therefore, by modifying or distributing the Program (or any work
to do so, and all its terms and conditions for copying,
distributing or modifying the Program or works based on it.

·  Each time you redistribute the Program (or any work based on the
original licensor to copy, distribute or modify the Program subject
to these terms and conditions.  You may not impose any further
restrictions on the recipients' exercise of the rights granted
herein.  You are not responsible for enforcing compliance by third

·  If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent
issues), conditions are imposed on you (whether by court order,
agreement or otherwise) that contradict the conditions of this
License, they do not excuse you from the conditions of this
License.  If you cannot distribute so as to satisfy simultaneously
obligations, then as a consequence you may not distribute the
Program at all.  For example, if a patent license would not permit
royalty-free redistribution of the Program by all those who receive
copies directly or indirectly through you, then the only way you
could satisfy both it and this License would be to refrain entirely
from distribution of the Program.

If any portion of this section is held invalid or unenforceable
under any particular circumstance, the balance of the section is
intended to apply and the section as a whole is intended to apply
in other circumstances.

It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of
any such claims; this section has the sole purpose of protecting
the integrity of the free software distribution system, which is
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is
willing to distribute software through any other system and a

This section is intended to make thoroughly clear what is believed
to be a consequence of the rest of this License.

·  If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces,
the original copyright holder who places the Program under this
excluding those countries, so that distribution is permitted only
in or among countries not thus excluded.  In such case, this
License incorporates the limitation as if written in the body of

·  The Free Software Foundation may publish revised and/or new
versions of the General Public License from time to time.  Such new
versions will be similar in spirit to the present version, but may
differ in detail to address new problems or concerns.

Each version is given a distinguishing version number.  If the
Program specifies a version number of this License which applies to
it and any later version,'' you have the option of following the
terms and conditions either of that version or of any later version
specify a version number of this License, you may choose any

·  If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the
the Free Software Foundation, write to the Free Software
Foundation; we sometimes make exceptions for this.  Our decision
will be guided by the two goals of preserving the free status of
all derivatives of our free software and of promoting the sharing
and reuse of software generally.

NO WARRANTY

·  BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO
WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE
LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS
AND/OR OTHER PARTIES PROVIDE THE PROGRAM AS IS'' WITHOUT WARRANTY
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT
LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS
FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND
PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE PROGRAM PROVE
DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR
OR CORRECTION.

·  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY
MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE
LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL,
INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR
INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU
OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY
OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN
ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

END OF TERMS AND CONDITIONS

10.3.  How to Apply These Terms to Your New Programs

If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these
terms.

To do so, attach the following notices to the program.  It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the copyright'' line and a pointer to where the full notice is
found.

[one line to give the program's name and an idea of what it does.
Copyright (C) 19[yy]  [name of author]
