+% \maketitle
+%
+% \begin{documentation}
+%
+% Sometimes it's useful for some explanation to provide lengths in
+% standardizations units instead of the default unit of \TeX. 
+% This package can do this for your.
+% 
+%
+% \tableofcontents
+%
+% \section{Basics}
+%
+% The package needs the newest version of \pkg{l3kernel} available at CTAN. 
+% Internally it uses the modul \pkg{l3fp} to convert the length. 
+%
+% All allowed units in \TeX\ are listed in the table below.
+%
+% \begin{table}[!ht]
+% \centering
+% \caption{Allowed \TeX\ units}
+% \vspace*{1em}
+% \begin{tabular}{cl}
+%  \toprule
+%    \textbf{Unit} & \textbf{Measurement}                 \\
+%  \midrule
+%    pt            &  point                               \\
+%    pc            &  pica(1pc=12pt)                      \\
+%    in            &  inch (1 in = 72.27 pt)              \\
+%    bp            &  bigpoint(72bp=1in)                  \\
+%    cm            &  centimeter (2.54 cm = 1 in)         \\
+%    mm            &  millimeter (10 mm = 1 cm)           \\
+%    dd            &  didot point (1157 dd = 1238 pt)     \\
+%    cc            &  cicero (1 cc = 12 dd)               \\
+%    sp            &  scaled point (65536 sp = 1 pt)      \\
+%  \bottomrule
+% \end{tabular}
+% \end{table}
+%
+%
+% \section{Usage}
+% 
+% The usage is really simple. Pass the length to the command \cs{Convert}
+% and get the result.
+%
+% \begin{function}{\Convert}
+%   \begin{syntax}
+%     \cs{Convert}\oarg{options} \Arg{length}
+%   \end{syntax}
+% \end{function}
+% The command converts the given length to the unit specified by an option. The
+% default unit is cm.
+% After the conversion the result will be printed.
+%
+% \begin{function}{\Convertsetup}
+%   \begin{syntax}
+%     \cs{Convertsetup} \Arg{options}
+%   \end{syntax}
+% \end{function}
+% Allows the specification of options.
+%
+% \section{Options}
+%
+% The package is simple and the options too. 
+%
+%\DescribeOption{unit}
+% The option accepts only the abbrevation unit. Allowed units are described in
+% the table above. 
+
+% You can also use only the abbrevation or a complete word. The following table
+% lists all allowed inputs.
+%
+%
+% \begin{center}
+% \def\arraystretch{1.4}
+% \begin{tabular}{*{6}{c}}
+%  \toprule
+% pt        & pc         & in         & bp          & cm     & mm           \\
+% dd        & cc         & sp         & point       & pica   & inch         \\
+% big-point & centimeter & millimeter & didot-point & cicero & scaled-point \\
+%  \bottomrule
+% \end{tabular}
+%
+% \end{center}
+%
+%
+%
+%\DescribeOption{use-siunitx}
+% It's a bool flag which can be either \texttt{true} or \texttt{false}.
+% If it is true, the output of the new length is done by the package 
+% \pkg{siunitx} using the command \cs{SI}.
+%
+%\DescribeOption{precision}
+% This option accepts an integer and specifies the precision of the output.
+%
+%\DescribeOption{number-only}
+% It's a bool flag which can be either \texttt{true} or \texttt{false}.
+% If it's true, only the number is printed.
+%
+% \section{Examples}
+%  Some examples are shown in the following table. In the left column
+%  you see the input and in the right the output.
+%
+% \begin{center}
+% \def\arraystretch{1.4}
