+% \begin{documentation}
+% \begin{abstract}
+% There are several barcode packages out in the world, but they either need
+% PStricks, or are restricted to EAN-13 barcodes.  And most of all, they are
+% all \LaTeXe.  I've decided to write a package, that supports several GS1
+% codes, and at almost the same time, I've decided to give L3 a chance.  So
+% I've started an experimental GS1 package using \pkg{expl3}.  Using
+% \pkg{expl3} was the main reason writing this package.
+% \end{abstract}
+%
+% \tableofcontents
+%
+% \section*{Preface}
+%
+% Design and implementation of this package based on
+% \begin{quote}\begin{description}
+% \item[GS1:] ``Allgemeine GS1 Spezifikation'', Version~12.0, Januar~2012,
+% Ausgabe~1.
+% \end{description}\end{quote}
+% This is the official GS1 specification for Germany, Austria and Switzerland.
+%
+% Currently only EAN-8 and EAN-13 codes and bar codes without extension have
+% been implemented.  Others may follow in future.
+%
+%
+% \section{L3 Functions and Variables for GS1 Codes}
+% \label{sec:doc:functions.and.variables}
+%
+% First of all: Please note, that the concept of private functions and
+% variables is not well defined in \TeX.  Several variables, that I'd have
+% made private in C++, haven't been declared to be private in this
+% implementation.  Maybe I should change this.
+%
+% You should also know, that several test files may be created from the
+% package source, and each of those may be used as an example for using the
+% code.  Nevertheless, \LaTeXe{} users will not need the following functions
+% and should continue reading with \autoref{sec:doc:latex2e}.
+%
+% \begin{function}{\GS_set_code_digit_seq:Nn}
+%   \begin{syntax}
+%     "\GS_set_code_digit_seq:Nn" \meta{GS1 sequence variable} \Arg{token list}
+%   \end{syntax}
+%   Makes a GS1 sequence, that consist in digits only, from a \meta{token
+%   list}.  To do so, only the tokens from 0 up to 9 of the \meta{token list}
+%   are set to the \meta{GS1 sequence variable}.  All other tokens are
+%   ignored.  So may, e.g., convert the string ``ISBN 978-3-86541-459-5'' into
+%   a GS1 sequence with the digits ``9783865414595'', where each digit is one
+%   item of the sequence.
+% \end{function}
+%
+% \begin{function}{\GS_cut_EAN_control_digit:N}
+%   \begin{syntax}
+%     "\GS_cut_EAN_control_digit:N" \meta{GS1 sequence variable}
+%   \end{syntax}
+%   The \meta{GS1 sequence variable} should store either a EAN-8 or EAN-13
+%   code with or without control digit.  If the code has seven or twelve
+%   digits, nothing happens.  If the code has eight or 13 digits, the last one
+%   will be removed.  All other cases result in an error message.
+% \end{function}
+%
+% \begin{function}{\int_set_to_EAN_control_digit:NN}
+%   \begin{syntax}
+%     "\int_set_to_EAN_control_digit:NN" \meta{integer variable} \meta{GS1 sequence variable}
+%   \end{syntax}
+%   Calculates the control digit of the \meta{GS1 sequence variable} using the
+%   EAN control digit algorithm and stores it into the \meta{integer
+%   variable}.  Note, that the \meta{GS1 sequence variable} may be a sequence
+%   of digits of any length not only seven digits for EAN-8 or twelve digits
+%   for EAN-13.
+% \end{function}
+%
+% \begin{function}{\GS_use_as_EAN_barcode:N}
+%   \begin{syntax}
+%     "\GS_use_as_EAN_barcode:N" \meta{GS1 sequence variable}
+%   \end{syntax}
+%   Prints an EAN-8 or EAN-13 bar code depending on
+%   \cs{l_GS_code_size_int}. Note, that the \meta{GS1 sequence variable} may
+%   have more than 8 resp. 13 items but not less!  Use \cs{EANBarcode} if you
+%   need a more save function.
+% \end{function}
+%
+%
+% \section{\LaTeXe{} User Interface for GS1 Codes}
+% \label{sec:doc:latex2e}
+%
+% This section describes the \LaTeXe-compatible user interface.  Note, that
+% the test files \file{EANControlDigit.tex}, \file{EANBarcode.tex},
+% \file{GSSetup.tex}, and the resulting PDF files may be used as examples of
+% the following commands.
+%
+% \begin{function}{\EANControlDigit}
+%   \begin{syntax}
+%     "\EANControlDigit"\Arg{string}
+%   \end{syntax}
+%   Only the digits of the \meta{string} will be used. All other tokens
+%   will be ignored.  If the \meta{string} has 7 or 8 digits, the control
+%   digit of an EAN-8 code will be calculated and output.  If the
+%   \meta{string} has 12 or 13 digits, the control digit of an EAN-13 code
+%   will be calculated and output.  If the \meta{string} has 8 or 13 digits
+%   the last digit will be ignored.  Any other number of digits will result in
+%   an error message.
+% \end{function}
+%
+% \begin{function}{\EANBarcode}
+%   \begin{syntax}
+%     "\EANBarcode"\oarg{options}\Arg{string}
+%   \end{syntax}
+%   Creates the EAN bar code corresponding with \meta{string}.  The optional
+%   argument \meta{options} may be used to use different settings from the
+%   defaults set by \cmd{\GSSetup}.  
+%
+%   Each digit of a EAN bar code is represented by seven modules.  Each module
+%   is either black or white.  A black module is a black, vertical line.  A
+%   white module is just a gap.  The seven modules start either with a black
+%   sequence of up to four modules, followed by a white sequence of up to four
+%   modules, followed by a black sequence of up to four modules, finished by a
+%   white sequence of up to four modules, or they start with a white sequence
+%   of up to four modules, followed by a black sequence of up to four modules,
+%   followed by a white sequence of up to four modules, finished by a black
+%   sequence of up to four modules.
+% \end{function}
+%
+% \begin{function}{\GSSetup}
+%   \begin{syntax}
+%     "\GSSetup" \Arg{options}
+%   \end{syntax}
+%   \meta{options} is a list of \meta{key}=\meta{value} pairs.  They are used
+%   to setup the default of several settings:
+%   \begin{description}
+%     \item[\texttt{ocrb=}\meta{boolean}]\hfill\\
+%       If \meta{boolean} is \texttt{true} the digits at the bottom of the bar
+%       code will be printed using OCR-b font ocrb/T1/m/n in 9pt.  Predefined
+%       default is |ocrb=true|.
+%     \item[\texttt{module\_width=}\meta{dimension expression}]\hfill\\
+%       This is the width of one module.  GS1 specifies a minimum module width
+%       of 0.264\,mm and a normal width of 0.33\,mm.  You should not set a
+%       width below the minimum!
+%     \item[\texttt{module\_height=}\meta{dimension expression}]\hfill\\
+%       This is the height of a black module.  GS1 specifies a normal bar code
+%       height of 21.31\,mm for EAN-8 and 25.01\,mm for EAN-13.  Both values
+%       are inclusive the digits at the bottom of the bar code.  Some marker
+%       modules are higher than the digit modules.
+%     \item[\texttt{code=}\meta{string}]\hfill\\
+%       The \meta{string} should either be \texttt{EAN-8} or \texttt{EAN-13}.
+%       The predefined default is |EAN-13|.  More types will be
+%       supported in future.
+%     \item[\texttt{scale=}\meta{floating point}]\hfill\\
+%       This is the scale factor for the bar code.  GS1 specifies scale classes
+%       from 0.8 up to 2.0 with steps of 0.05.  Factors less than 0.8
+%       shouldn't be used. \emph{Currently \texttt{scale} won't be used!}
+%     \item[\texttt{scale\_to\_font=}\meta{boolean}]\hfill\\
+%       Ignore \texttt{scale} and calculate your own scale by the width of
+%       digit 0 of the current font. \emph{See note to \texttt{scale} above!}
+%     \item[\texttt{add\_control=}\meta{boolean}]\hfill\\
+%       Add the control digit to the GS1 code.  If there's already a control
+%       digit, replace it by the calculated one.  The predefined default is
+%       |add_control=false|.
+%    \end{description}
+% \end{function}
+%
+%
+% \section{Internal Functions and Variables}
+% \label{sec:doc:internal}
+%
+% You should not use or manipulate these! So, maybe it's better to stop
+% reading now.
+%
+% \begin{function}{\__GS_set_key_code:nn}
+%   \begin{syntax}
+%     "\__GS_set_key_code:nn" \Arg{token list} \Arg{integer expression}
+%   \end{syntax}
+%   Sets \cs{l_GS_code_type_tl} to \meta{token list} and
+%   \cs{l_GS_code_size_int} to value of \Arg{integer expression}.
+% \end{function}
+%
+% \begin{function}{\__GS_new_seq_c:cn}
+%   \begin{syntax}
+%     "\__GS_new_seq_c:cn" \Arg{sequence name} \Arg{token list}
+%   \end{syntax}
+%   Creates a sequence constant \cs{c__GS_\meta{sequence name}_seq}.  The
+%   value of the constant will be build by the tokens of the \meta{token
+%   list}.  These tokens should be either characters ``A'' or ``B'' for
+%   selection constants or digits 1--4 for module constants.
+% \end{function}
+%
+% \begin{function}{\__GS_modules:Nn, \__GS_modules:cn, \__GS_modules:NnN}
+%   \begin{syntax}
+%     "\__GS_modules:Nn" \meta{sequence variable} \Arg{dimension expression}
+%     "\__GS_modules:cn" \Arg{sequence variable name} \Arg{dimension expression}
+%     "\__GS_modules:NnN" \meta{sequence variable} \Arg{dimension expression} \meta{boolean variable}
+%   \end{syntax}
+%   Draws the modules given by the \meta{sequence variable} with height
+%   \Arg{dimension expression}. The arguments are:
+%   \begin{arguments}
+%   \item \meta{sequence variable} or \meta{sequence variable name}, each item
+%     of the sequence stays for a number of modules with the same color.
+%     \cs{l__GS_black_bool} signals, whether the (first) modules are black or
+%     white and will be reversed after every item.  Each module has the width
+%     \cs{l_GS_module_wd_dim}.
+%   \item \meta{dimension expression}, the height of the black modules. The
+%     modules will be raised by \cs{l_GS_module_ht_dim}.
+%   \item \meta{boolean variable}, \texttt{true} indicates, that the first
+%     module should be black. With \texttt{false}, the first module will be
+%     white.
+%   \end{arguments}
+% \end{function}
+%
+% \begin{function}{\__GS_modules_start_black:Nn}
+%   \begin{syntax}
+%     "\__GS_modules_start_black:Nn" \meta{sequence variable} \Arg{dimension expression}
+%   \end{syntax}
+%   Same like \cs{__GS_modules:NnN} \meta{sequence variable} \Arg{dimension
+%   expression} \cs{c_true_bool}.
+% \end{function}
+%
+% \begin{function}{\__GS_modules_start_white:Nn}
+%   \begin{syntax}
+%     "\__GS_modules_start_white:Nn" \meta{sequence variable} \Arg{dimension expression}
+%   \end{syntax}
+%   Same like \cs{__GS_modules:NnN} \meta{sequence variable} \Arg{dimension
+%   expression} \cs{c_false_bool}.

+% \maketitle
+%
+% \begin{documentation}
+%   At \LaTeXe{} you have command \cmd{\rule} to make horizontal and vertical
+%   rules and even boxes.  Currently there's no L3 command for this.  This
+%   module provides two new L3 functions for rules.  The ``-D'' in the module
+%   name indicates, that currently the implementation uses deprecated
+%   functions like \cmd{\tex_vrule:D}.  Nevertheless, the new rule functions
+%   aren't declared to be deprecated.
+%
+%   This package has been made only, because \pkg{GS1} needs such rule
+%   functions.  So maybe it's simply a helper package for \pkg{GS1}.
+%
+%
+% \begin{function}{\rule:nn , \rule:nnn}
+%   \begin{syntax}
+%     "\rule:nnn" \Arg{dimexpr_{raise}} \Arg{dimexpr_{width}}^^A
+% \Arg{dimexpr_{height}}
+%     "\rule:nn"  \Arg{dimexpr_{width}} \Arg{dimexpr_{height}}
+%   \end{syntax}
+%   Draw a rule of width \meta{dimexpr_{width}}, height
+%   \meta{dimexpr_{height}} and raise it by \meta{dimexpr_{raise}}. It the
+%   \meta{dimex_{raise}} has not been given, the rule will be drawn at the
+%   base line.
+% \end{function}

+% \end{documentation}
