# A bare-bones sample file

The basic structure of a Prosper input file is pretty simple. Consider the file sample.tex, the content of which is shown below:

% sample.tex
\documentclass[pdf,azure,slideColor,colorBG]{prosper}
\begin{document}

\begin{slide}{Elementary mathematics}

Observations:

$\int_{-\infty}^\infty e^{-x^2} \, dx = \sqrt{\pi}$

$e^{i\pi} = -1$

Conclusions:

\begin{itemize}
\item $\sqrt{2}$ is irrational
\item $e$ and $\pi$ are transcendental
\item $42$ and 42 are not the same in \LaTeX
\end{itemize}

\end{slide}

\end{document}


The input file above produces the following single slide:

The \begin{slide}{}...\end{slide} block can be repeated any number of times to produce a sequence of slides.

Important! Every Prosper slide has a mandatory slide title. The line:

\begin{slide}{Elementary mathematics}


specifies "Elementary mathematics" as title for this slide. It is an error to omit the slide title.
