I guess I wasn't clear...

If I use the option `toc' for the export:

--8<---------------cut here---------------start------------->8---
#+OPTIONS:   toc:t
--8<---------------cut here---------------end--------------->8---

then I get a slide with the table of contents. Automatically. The only
"criticism" I did is that there was no title to the generated frame.

Hence, the workaround was setting the `toc' option to `nil' and adding such a
code by myself:

--8<---------------cut here---------------start------------->8---
#+BEAMER: \frame{\frametitle{Outline}\tableofcontents}
--8<---------------cut here---------------end--------------->8---

But better (IMHO) would be that such a code gets inserted automatically (with
a frame title set, for example, to `Outline') when the `toc' export option is
set to `t', and when we're in a beamer class.

Is it better expressed?

Better is:

--8<---------------cut here---------------start------------->8---
#+BEGIN_BEAMER
\AtBeginSection[] % Do nothing for \section*
{
  \begin{frame}<beamer>
    \frametitle{Outline}
    \tableofcontents[currentsection]
  \end{frame}
}
#+END_BEAMER
--8<---------------cut here---------------end--------------->8---

Thanks Eric and Christian for your input on this!

Best regards,
