 @noindent
 The @code{jobname} option is there because otherwise both files would be
-called @file{main.pdf} and the second would overwrite the first. (See
+called @file{main.pdf}, and the second would overwrite the first. (See
 the next section.)
 
-In this example, we pass the @code{draft} option to the
- at file{graphicx} package:
+In this example we use the command line to select which parts of a
+document to include.  For a book named @file{mybook.tex} and structured
+like this.
 
 @example
-pdflatex "\PassOptionsToPackage@{draft@}@{graphicx@}\input@{aa.tex@}"
- at end example
-
- at noindent
-so the graphic files are read for their bounding box size information
-but replaced in the PDF by a box with same size and that contains only
-the file name, which speeds up compilation time and saves printer ink.
-
- at c xx to be translated to English.
- at ignore
-Un autre exemple classique est de cribler certains chapitres à la
-compilation en les passant à @code{\includeonly} dans la ligne de
-commande. Ainsi, supposons qu'on a un fichier racine @file{livre.tex}
-ainsi formé :
-
- at example
 \documentclass@{book@}
 \begin@{document@}
-\frontmatter
-\include@{pref@} 
-\mainmatter
+   ...
 \include@{chap1@} 
 \include@{chap2@}
-\appendix
-\include@{append@}
-\backmatter
-\include@{bib@} 
+  ...
 \end@{document@}
 @end example
 
-En compilant @file{livre.tex} avec la ligne de commande suivante :
-
- at example
-pdflatex '\includeonly@{chap1@}\input@{livre@}
- at end example
-
 @noindent
-seul le chapitre contenu dans @file{chap1.tex} sera produit en
-sortie. @xref{Splitting the input}.
+the command line
 
-Dans ce dernier exemple, on force la date au 14 juillet 1789 :
-
 @example
-pdflatex '\day=14 \month=7 \year=1789 \input revolution'
+pdflatex "\includeonly@{chap1@}\input@{mybook@}"
 @end example
 
-Ainsi, si le fichier @file{revolution.tex} contient ceci :
-
- at example
-\documentclass[french]@{minimal@}
-\usepackage@{babel@}
-\begin@{document@}
-\today\ c'est la Révolution~!
-\end@{document@}
- at end example
-
 @noindent
-alors vous aurez en sortie un truc du genre :
+will give output that has the first chapter but no other
+chapter. @xref{Splitting the input}.

-14 juillet 1789 c'est la Révolution !

+---------------------------------------------------------
+
+When reading input TeX converts the sequences of read characters into a
+sequence of "tokens".  When TeX sees a backslash '\', it will handle the
+following characters in a special way in order to make a "control
+sequence" token.
+
+   The control sequences fall into two catagories:
+
+   * "control word", when the control sequence is gathered from a '\'
+     followed by at least one ASCII letter, followed by at least one
+     blank.  The sequence of at least one ASCII letter is called the
+     "control sequence name".
+   * "control symbol", when the control sequence is gathered from a '\'
+     followed by one non-letter character.
+
+   Blanks after a control word are ignored and do not produce any
+whitespace in the ouput (*note \newcommand & \renewcommand:: and *note

+
+   Just as the '\relax' command does nothing, the following will print
+'Hello!'--if you use the Emacs info viewer, turn on the whitespace-mode

+16.7 Math styles
+================
+
+TeX's rules for typesetting a formula depend on the context.  For
+example, inside a displayed equation, the input '\sum_{0\leq
+i<n}k^m=\frac{n^{m+1}}{m+1}+\mbox{lower order terms}' will give output
+with the summation index centered below the summation symbol.  But if
+that input is inline then the summation index is off to the right rather
+than below, so it won't push the lines apart.  Similarly, in a displayed
+context, the symbols in the numerator and denominator will be larger
+than for an inline context, and in display math subscripts and
+superscripts are further apart then they are in inline math.
+
+   TeX uses four math styles.
+
+   * Display style is for a formula displayed on a line by itself, such
+     as with '\begin{equation} ... \end{equation}'.
+
+   * Text style is for an inline formula, as with 'so we have $ ... $'.
+
+   * Script style is for parts of a formula in a subscript or
+     superscript.
+
+   * Scriptscript style is for parts of a formula at a second level (or
+     more) of subscripting or superscripting.
+
+   TeX determines a default math style but you can override it with a
+declaration of '\displaystyle', or '\textstyle', or '\scriptstyle', or
+'\scriptscriptstyle'.
+
+   In this example, the 'Arithmetic' line's fraction will look
+scrunched.
+
+     \begin{tabular}{r|cc}
+       \textsc{Name}  &\textsc{Series}  &\textsc{Sum}  \\  \hline
+       Arithmetic     &$a+(a+b)+(a+2b)+\cdots+(a+(n-1)b)$
+                        &$na+(n-1)n\cdot\frac{b}{2}$  \\
+       Geometric      &$a+ab+ab^2+\cdots+ab^{n-1}$
+                        &$\displaystyle a\cdot\frac{1-b^n}{1-b}$  \\
+     \end{tabular}
+
+But because of the '\displaystyle' declaration, the 'Geometric' line's
+fraction will be easy to read, with characters the same size as in the
+rest of the line.
+
+   Another example is that, compared to the same input without the
+declaration, the result of
+
+     we get
+     $\pi=2\cdot{\displaystyle\int_{x=0}^1 \sqrt{1-x^2}\,dx}$
+
+will have an integral sign that is much taller.  Note that here the
+'\displaystyle' applies to only part of the formula, and it is delimited
+by being inside curly braces, as '{\displaystyle ...}'.
+
+   The last example is a continued fraction.
+
+     \begin{equation}
+     a_0+\frac{1}{
+            \displaystyle a_1+\frac{\mathstrut 1}{
+            \displaystyle a_2+\frac{\mathstrut 1}{
+            \displaystyle a_3}}}
+     \end{equation}
+
+Without the '\displaystyle' declarations, the denominators would be set
+in script style and scriptscript style.  (The '\mathstrut' improves the
+height of the denominators; *note \mathstrut::.)

 25.2 Indexes
 ============
 
-This document has an index.
+If you tell LaTeX what terms you want to appear in an index then it can
+produce that index, alphabetized and with the page numbers automatically
+maintained.  This illustrates the basics.
 
      \documentclass{article}
-     \usepackage{makeidx} \makeindex
+     \usepackage{makeidx}  % Provide indexing commands

-     Recall Wilson's Theorem: \index{Wilson's Theorem}
-     a number \( n>1 \) is prime if and only if the factorial of \( n-1 \)
-     is congruent to \( -1 \) modulo~\( n \).
+     Wilson's Theorem\index{Wilson's Theorem}
+     says that a number $n>1$ is prime if and only if the factorial
+     of $n-1$ is congruent to $-1$
+     modulo~$n$.\index{congruence!and Wilson's Theorem}
        ...
      \printindex
-       ...
+     \end{document}
 
-The '\usepackage{makeidx}' and '\makeindex' in the preamble bring in the
-relevant commands.
+As that shows, declare index entries with the '\index' command (*note
+\index::).  When you run LaTeX, the '\index' writes its information,
+such as 'Wilson's Theorem' and the page number, to an auxiliary file
+whose name ends in '.idx'.  Next, to alphabetize and do other
+manipulations, run an external command, typically 'makeindex' (*note
+makeindex::), which writes a file whose name ends in '.ind'.  Finally,
+'\printindex' brings this manipulated information into the output (*note
+\printindex::).
 
-   Producing an index is a three stage process.  First, in the document
-body you declare index entries with the '\index' command (*note
-\index::).  When you run LaTeX, the '\index' writes its information to
-an auxiliary file 'ROOT-NAME.idx'.  Next, to alphabetize and to do other
-manipulations you run an external command, typically 'makeindex' or
-'xindy' (*note makeindex::).  These output a file 'ROOT-NAME.ind'.
-Finally, you bring the information back into your document and typeset
-it with the '\printindex' command (*note \printindex::).
+   Thus, if the above example is in the file 'numth.tex' then running
+'pdflatex numth' will save index entry and page number information to
+'numth.idx'.  Then running 'makeindex numth' will alphabetize and save
+the results to 'numth.ind'.  Finally, again running 'pdflatex numth'
+will show the desired index, at the place where the '\printindex'
+command is in the source file.
 
+   There are many options for the output.  An example is that the
+exclamation point in '\index{congruence!and Wilson's Theorem}' produces
+a main entry of 'congruence' with a subentry of 'and Wilson's Theorem'.
+For more, *note makeindex::.
+
+   The '\makeindex' and '\printindex' commands are independent.  Leaving
+out the '\makeindex' will stop LaTeX from saving the index entries to
+the auxiliary file.  Leaving out the '\printindex' will cause LaTeX to
+not show the index in the document output.
+
    There are many packages in the area of indexing.  The 'showidx'
 package causes each index entries to be shown in the margin on the page
 where the entry appears.  This can help in preparing the index.  The
