  \begin{slide}{Introduction}    
    \begin{itemstep}
    \item \textcolor{blue}{\emph{Prosper}} is a plain \LaTeX\ packet.
      All common \LaTeX\  macros are available.
    \item Produces Postscript for printing \textcolor{blue}{slides}
      and \emph{P}ortable \emph{D}ocument \emph{F}ormat (PDF) files
      for \textcolor{blue}{presentations}.
    \item Presentations are viewed with the \textcolor{blue}{Acrobat
        reader}.  Common on many computer systems.
    \item System independent (Windows, UNIX, Mac, \ldots)
    \end{itemstep}    
  \end{slide}
}

\overlays{4}{
  \begin{slide}{Features}
    \begin{itemstep}
    \item Simple structure, few new commands
    \item New step-by-step itemisation environment (as seen)
    \item Various transition types between slides: Replace, Split,
      Blinds, Box, Wipe, Dissolve, Glitter
    \item Possibility to create own styles
    \end{itemstep}
  \end{slide}

  \begin{slide}{Add, replace, delete}
    
    \onlySlide*{1}{Items can be \textcolor{blue}{added}}
    \onlySlide*{2}{\ldots or \textcolor{green}{replaced}}
    \FromSlide{3} Items can be \textcolor{blue}{added},
    \textcolor{green}{replaced} and \textcolor{red}{deleted}

    \FromSlide{4} This works in normal text, itemisation environments
    and math formulae:

    Induction equation \onlySlide{4}{(ideal MHD)}

    \begin{displaymath}
      \partial_t \vec B 
      = 
      %% white text trick to supress a jump at slide change
      %% not realy necessary
      \onlySlide*{4}{  
        \textcolor{blue}{\mathbf{curl}\left(\vec v\times\vec B\right)}
        \textcolor{white}{+\frac{c^2}{4\pi\sigma}\triangle\vec B}
        }
      \fromSlide*{5}{
        \rnode{ft}{\textcolor{blue}{\mathbf{curl}\left(\vec v\times\vec B\right)}}
        +\rnode{st}{\textcolor{red}{\frac{c^2}{4\pi\sigma}\triangle\vec B}}
        }
      %% the arguments \fromSlide,\onlySlide,\untilSlide makros are
      %% not included in the PS version.  The stuff after \FromSlide
      %% is included, though.  One has to add this extra:
      \onlyInPS{
        \rnode{ft}{\textcolor{blue}{\mathbf{curl}\left(\vec v\times\vec B\right)}}
        +\rnode{st}{\textcolor{red}{\frac{c^2}{4\pi\sigma}\triangle\vec B}}
        }
    \end{displaymath}\\[2em]
