%
% \begin{abstract}
% This file describe the \textsf{syntrace} package. This package is intended for \LaTeX\ users who must deal with
% traces in synttree.
% \end{abstract}
%
% \section{Options}
%
% \DescribeMacro{synttree} The |synttree| option add the synttree command of the synttree package to the auto reset commands. With this option, the |\synttree| command is redefined to auto reset trace counter. A |\synttree*| command is add that work like |\synttree|, but without auto reset. This option is enabled is a default options.
%
% \DescribeMacro{qtree} The |qtree| option add the Tree command of the qtree package to the auto reset command.
%
% \DescribeMacro{i-start} The |i-start| change the first label of trace to i instance of a.
%
% \section{Usage}
% The \textsf{syntrace} package add a way to deal with trace in tree produce using the \textsf{synttree} package.
%
% \DescribeMacro{\traceLabel} The |\traceLabel{label}| set and draw a end trace. The parameter is the label to use for
% the reference.
%
% \DescribeMacro{\traceReference} The |\traceReference{ref}| draw a trace linked with the specified reference.
%
% \DescribeMacro{\syntraceresetmacro} The |\syntraceresetmacro{commande name without slash}| add auto-reset to this command.
%
% \section{Examples}
