+% \maketitle
+%
+% \begin{abstract}
+% This package provides an interface to the symbol of shuffle product
+% which is used in some area of mathematics such as algebra.
+% \end{abstract}
+%
+% \section{The shuffle product symbol}
+%
+% \begin{quote}
+% \textbf{Dependencies: } this package uses the \MF\ files |shuffle.mf|,
+% |shuffle7.mf| and |shuffle10.mf|. These files should be put
+% into the |font/source/| directory of your |texmf| tree (do not
+% forget to perform |texhash| or an equivalent command).
+% \end{quote}
+%
+% This package provides the following two symbols
+% \begin{center}
+% \begin{tabular}{l l l}
+% Shuffle product & $\shuffle$ & \verb+\shuffle+ \\
+% Complete shuffle product & $\cshuffle$ & \verb+\cshuffle+ \\
+% \end{tabular}
+% \end{center}
+%
+% In a space of formal non-commutative polynomials whose indeterminates
+% are identified with letters (and then the product of indeterminates
+% are identified with words), the shuffle product
+% $u\shuffle v$ of two words
+% $u=u_1\dotsb u_n$ and $v=v_1\dotsb v_n$
+% is defined as the sum of the all words it is possible to
+% construct from $u$ and $v$ by preserving
+% the order of all the letters in each of the words.
+% For example
+% \[
+% \alpha\beta \shuffle \gamma= \gamma\alpha\beta+\alpha \gamma \beta+\alpha \beta\gamma.
+% \]
+%
+% The shuffle product is used in combinatorics and algebra
+% (notably for free Lie algebra \cite{reutenauer} and Hopf algebra) and
+% has applications for example in the formal resolution
+% of controlled differential equations.
+%
+% The symbol $\shuffle$ is a standard notation
+% but is does not seem to have already been provided for \LaTeX{}.
+% The \MF{} source of this symbol has
+% been designed by J. Gilbey for his own usage \cite{gilbey},
+% where the notion of complete shuffle product~$\cshuffle$
+% is also defined.
+%
+% The symbol $\shuffle$ is also defined as a Unicode
+% symbol at position |29E2| \cite{unicode} under
+% the name |SHUFFLE PRODUCT|.
