 \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}
