\begin{document}
The starting place for the \texttt{wrapfigure}
environment was manually determined in
\begin{wrapfigure}[7]{l}[0.2\width]{0pt}
  \centering  \fbox{This is a ``wrapfigure''.}
  \caption{An example of the
    \texttt{wrapfigure} environment}
\end{wrapfigure}
the current example by first setting the text
without the figure to find the natural
line breaks. \par
The figure was then inserted after the second
line giving the results that you see here.
