  \section*{Symbols in textcomp}

  To use the symbols provided by the package \verb|textcomp| include
  this line:
  \begin{verbatim}
    \usepackage{textcomp}
  \end{verbatim}
  The symbols are used by calling them by their name. E.g. \textleaf:
  \verb|\textleaf|.
  
  In mathematics the package \verb|mathcomp| works. Then the prefix
  \verb|text| is replaced by \verb|tc|, for \emph{t}ext\emph{c}omp:
  \begin{verbatim}
    \usepackage{mathcomp}
    ...
    $\tcleaf$
  \end{verbatim}
\end{minipage}%

  \section*{Symbole in textcomp}

  Die Symbole des Paketes \verb|textcomp| werden folgenderma"sen verwendet:
  \begin{verbatim}
    \usepackage{textcomp}
  \end{verbatim}
  Dann die Symbole mit ihren Namen aufrufen: Zum Beispiel f"ur 
  \textleaf: \verb|\textleaf|.
  
  Im Mathematikmodus funktioniert das Paket mathcomp. Dann wird der
  Prefix \verb|text| durch \verb|tc| f"ur \emph{t}ext\emph{c}omp ersetzt:
  
  \begin{verbatim}
    \usepackage{mathcomp}
    ...
    $\tcleaf$
  \end{verbatim}
