%\section{Introduction}
%\label{sec:intro}
%This package allows easy setting of simple dna-sequences in
%userdefined grouping, with numbering of bases (at the begin of
%each line.
%
%If you need to typeset alignments, have a look at the
%\texttt{texshade}-Package.
%
% The main code has been posted by Andreas Matthias
% \texttt{<amat@kabsi.at>} on \texttt{de.comp.text.tex} and is based
% by itself on old code from Anselm Lingnau.
%\section{Usage}
%\label{sec:usage}
%
%\subsection{DNA}
%\DescribeMacro{\DNA}
%\verb|\DNA| is the main macro of this package. It is used as
%following:
%\begin{verbatim}
%\DNA! actctgctagtcgatgcat!
%\end{verbatim}
%where the delimiting character \verb|!| can be any normal character.
%
%Within the argument you can use \verb|'{<color>}| to change the color
%of your bases. The color names are normal color.sty names.
%Look at the full example for more info.
%
%\subsection{Configuration}
%
%\DescribeMacro{\DNAblock}The macro \verb|\DNAblock| stores the desired blocking intervall of
%your sequence. Just do a \verb|\renewcommand{\DNAblock}{<some number>}|
%to change the default of 10.
%
%\DescribeMacro{\DNAreserve}The macro defines how much space to reserve
%for the numbering of bases.
%To change, do a \verb|\renewcommand{\DNAreserve}{<template>}| The
%default template is \verb|0000| allowing for for digit numbering.
