I putting together a presentation using org and exporting to beamer.  I was
wondering if there is easy way to get each item in a list to display
incrementally.  Beamer supports this with the \begin{itemize}[<+->]
environment option.  Perhaps this could be achieved by extending the
#+ATTR_LaTeX: syntax.  Ideally I would like the following

** Overlays
#+ATTR_LaTeX: <+->
- one
- two
- three
- four
- five

to be exported as

\frametitle{Overlays}
\label{sec-1-10}
\begin{itemize}[<+->]
\item one
\item two
\item three
\item four
\item five
\end{itemize}
\end{frame}

Or is there already a way of achieving this? Come to think of it, prehaps
#+ATTR_beamer would be better for this?

Thanks
Chris.
