\subsection* {{\ActiveDVI} is really cool}
\begin{itemize}
\item {\bf a DVI} previewer for hackers written in Caml
\item You may hack your {\LaTeX} source file, your favorite style
file or the Caml code of the presenter.
\item You can launch arbitrary commands to animate your presentation!
\end{itemize}
\newpage
\bigskip
\subsection* {Slide strip-tease}
You can program pauses in your talk writing:
\verb"\adviwait"
\noindent
The mouse pointer is modified, and {\ActiveDVI} waits for you to press
the space bar to go on!
\adviwait
\subsection* {Color writing}
Using the macro \verb"textcolor" you can write text in the color you
want. For instance, \verb"\textcolor{red}{important}" is rendered as
\textcolor{red}{important}!
\adviwait
\subsection* {Color specification}
Following the conventions of the \verb"color.sty" {\LaTeX} package,
you can use predefined (or \verb"named") colors. Syntax is
\verb"\textcolor[named]{Color}{text}", as in
\def\bs{\char92}
{\tt{\bs textcolor[named]\{Green\}\{}%
\textcolor[named]{Green}{\tt{this example}}%
}{\tt{\}}}%
\subsection* {Writing program code}
The environment \verb"allt" is nice to write type-writer text
(presumably program samples). In environment \verb"allt" you can still
use your favorite {\LaTeX} macros, hence coloring text and changing
styles.
\begin{alltt}
{\it(* Colors with rgb specification are still available. *)}
\end{alltt}
\begin{alltt}
{\it{(* Remark that double semi-colon is mandatory *)}}
let x = 1\textcolor{red}{;;}
let r = \{foo = 1; bar = "toto"\};;
\textcolor[named]{Red}{let} z = r.foo;;
\end{alltt}
\newpage
\subsection* {Writing math in program code}
If you need math formulas into the environment \verb"alltt" insert
them into fancy parens \verb"\(" and \verb"\)".
\adviwait
\noindent
Write for instance \verb"\(\alpha \rightarrow \beta\)" to produce
$\alpha \rightarrow \beta$.
\adviwait
\bigskip
Note for mathmode inside \verb"alltt":\\
since characters \verb"^" and \verb"_" are written as
is in the \verb"alltt" environment, you need special macro
calls to simulate them in math mode. Use \verb"\sp"
(superscript) for \verb"^" and \verb"\sb" (subscript) for
\verb"_"; hence, you would write \verb"\(x\sp{2} + t\sb{0}\)"
to produce $x^2 + t_0$ in the program text. For instance:
\adviwait
\begin{alltt}
for i = 0 to Array.lenght v - 1 do
{\it{(* Remark the mandatory loop invariant:}} \(i\sp{2}>=0\) {\it{*)}}
v.(i) <- 2
done;;
\end{alltt}
\adviwait
