% \section{Implementation of the Letter Configuration Option Files}
%
% Most of the predefined letter configuration option files define a letter
% layout, e.g, depending on a norm. The main thing in this case is to setup
% pseudo-lengths. Sometimes additionally macros or commands are (re-)defined.
%
% \begin{macrocode}

% \subsection{The file header}
%
% The head has to identify the file:
