% \begin{abstract}
% The \textsf{dictionary} \LaTeX\ package provides utility macros
% helping to typeset a dictionary. With the help of the datatool
% package it can build a database of words and their translation. Such
% a database can then be used to create a dictionary like text.
% \end{abstract}
%
% \section{Introduction}
%
% Currently only an environment and a macro are provided.
%
% \section{Usage}
%
% To use the \textsf{dictionary} package both package options
% (\texttt{primary} and \texttt{secondary}) have to be passed before
% using the package macros.
%
% \subsection{Package options}
%
% The package options \texttt{primary} and \texttt{secondary} have to
% be passed to \textsf{dictionary}. The \texttt{primary} option sets
% the language first part of each dictionary's entry and the
% \texttt{secondary} option sets the language of the second part,
% typically the translation, of each dictionary's entry.
%
% \DescribeMacro{\entry}
%
% The \texttt{\textbackslash entry} macro is used inside the
% \texttt{dictionary} environment in order to add entries to the
% dictionary. It expects two parameters, the primary part and the
% secondary part.
%
% \DescribeEnv{dictionary}
%
% The \texttt{dictionary} environment represents a dictionary. It is
% empty at the beginning but can be filled with the
% \texttt{\textbackslash entry} macro.
