+%
+% \section{Introduction}
+% 
+% In mathematical equations, it is sometimes necessary to use indices
+% (subscript or superscript) that are positioned at the left side of a
+% symbol. 
+% In tensor mathematics, for instance, some notations use a transponed
+% sign at the left side of the symbol:
+% \begin{eqnarray*}
+% \fourIdx{\mathrm{t}}{}{}{}{\left(A_{ij}\right)} &=&
+% \left(A_{ji}\right)
+% \end{eqnarray*}
+% 
+% For symbols with a normal character height, this can be reached by
+% simply put the indices without an own symbol:
+% 
+% \noindent
+% \begin{minipage}[c]{0.79\linewidth}
+% \leavevmode\begin{verbatim}
+% ${_1^2}a_3^4$
+% \end{verbatim}
+% \end{minipage}
+% \begin{minipage}[c]{0.19\linewidth}
+% ${_1^2}a_3^4$
+% \end{minipage}
+% 
+% \noindent
+% Is the symbol larger, this leads to unsatisfactory results:
+% 
+% \noindent
+% \begin{minipage}[c]{0.79\linewidth}
+% \leavevmode\begin{verbatim}
+% ${_1^2}\left(\frac{1}{b}\right)_3^4$
+% \end{verbatim}
+% \end{minipage}
+% \begin{minipage}[c]{0.19\linewidth}
+% ${_1^2}\left(\frac{1}{b}\right)_3^4$
+% \end{minipage}
+% 
+% \noindent
+% If the subscripts on the left and right side are of different height,
+% the result is also unsatisfactory:
+% 
+% \noindent
+% \begin{minipage}[c]{0.79\linewidth}
+% \leavevmode\begin{verbatim}
+% ${^{(k)}_n}A^x_{\overline x\vert}$
+% \end{verbatim}
+% \end{minipage}
+% \begin{minipage}[c]{0.19\linewidth}
+% ${^{(k)}_n}A^x_{\overline x\vert}$
+% \end{minipage}
+% 
+% \noindent
+% A better output can be reached by using the package |fouridx.sty|:
+% 
+% \noindent
+% \begin{minipage}[c]{0.79\linewidth}
+% \leavevmode\begin{verbatim}
+% $\fourIdx{2}{1}{4}{3}{\left(\frac{1}{b}\right)}$
+% \end{verbatim}
+% \end{minipage}
+% \begin{minipage}[c]{0.19\linewidth}
+% $\fourIdx{2}{1}{4}{3}{\left(\frac{1}{b}\right)}$
+% \end{minipage}
+% 
+% \noindent
+% \begin{minipage}[c]{0.79\linewidth}
+% \leavevmode\begin{verbatim}
+% $\fourIdx{(k)}{n}{x}{\overline x\vert}A$
+% \end{verbatim}
+% \end{minipage}
+% \begin{minipage}[c]{0.19\linewidth}
+% $\fourIdx{(k)}{n}{x}{\overline x\vert}A$
+% \end{minipage}
+% 
+% \section{Usage of the package}
+% 
+% Two commands are provided by the package.
+% 
+% \DescribeMacro{\fourIdx}%
+% The \cs{fouridx} command has the syntax
+% \cs{fouridx}\marg{left superscript}\marg{left subscript}%
+% \marg{right superscript}\marg{right subscript}\marg{symbol}.
+% This command typesets the symbol \meta{symbol} with indices on the
+% left and on the right side.
+% Example:
+%
+% \noindent 
+% \begin{minipage}[c]{0.79\linewidth}
+% \leavevmode\begin{verbatim}
+% $\fourIdx1234{\left(\frac{1}{b}\right)}$
+% \end{verbatim}
+% \end{minipage}
+% \begin{minipage}[c]{0.19\linewidth}
+% $\fourIdx1234{\left(\frac{1}{b}\right)}$
+% \end{minipage}
+% 
+% \noindent
+% You may omit left or right indices by using empty arguments.
+%
+% The next example shows the same in the different mathematical
+% styles:
+% \def\asdf{\fourIdx1234{\left(\frac1b\right)}}%
+% \begin{displaymath}
+% \displaystyle\asdf\quad\textstyle\asdf\quad
+% \scriptstyle\asdf\quad\scriptscriptstyle\asdf
+% \end{displaymath}
