+To install, you can run `tex hyperbar.dtx` and copy the generated file `hyperbar.sty` to a directory in the search path of your TeX installation.
+For quick evaluation, you can also rename `hyperbar.dtx` to `hyperbar.sty` and use that file directly.

+% \title{The \pkg{hyperbar} package\thanks{This document
+% corresponds to \pkg{hyperbar}~v0.1, dated~2018/07/04.}}
+% \author{Marcel Kr\"uger \\ \href{mailto:tex@2krueger.de}{tex@2krueger.de}}
+%
+% \maketitle
+%
+% \begin{documentation}
+% This package extends the \pkg{hyperref} functionality for creating interactive forms to allow adding Barcode form fields supported by some modern PDF readers.
+% \section{Usage}
+% \begin{function}{\BarcodeField}
+% \begin{syntax}
+% |\BarcodeField|[
+% \meta{type},
+% width=\meta{Barcode width},
+% height=\meta{Barcode height},
+% tsv=\Arg{fields to encode in barcode},\meta{Further parameters}
+% ]{\meta{Some field name}}
+% \end{syntax}
+% Barcode fields can be used like ordinary form fields as documented in the hyperref manual, section ``PDF and HTML forms''. Especially all parameters documented there can be used in \meta{Further parameters}. There are some additional parameters specific to \cmd\BarcodeField:
+% \end{function}
+% \begin{description}
+% \item[\meta{type}] One of the parameters |qr|, |datamatrix| or |pdf417| can be used to select the format of the generated barcode. If no such parameter is given, a PDF417 barcode is used.
+% \item[symwidth] The horizontal distance between the modules of the barcode in pixel assuming a resolution of $300$ DPI. Default is $6$.
+% \item[symfactor] Only used for PDF417. The ratio between the height and the width of the modules. Must be one of the values $1, 2, 3, 4$. Default $4$.
+% \item[ecc] The level of redundancy added to the data for error correction. Not used for DataMatrix, valid values for QR-Codes are $0, 1, 2, 3$. For PDF417 the valid range are integer values between $0$ and $8$.
+% \item[tsv] This is used as |tsv={<field1>,<field2>,<...>}| to automatically generate the encoded value of the barcode as a combination of the form fields with names \meta{field1}, \meta{field2}, \dots.
+% The format is based on the Tab-separated value option of Adobe Acrobat with field names. The generated value contains two lines, the first line are all used field names separated by a tab, the secons line consists of the tab-separated values.
+%
+% If you prefer another format, the |calculate| parameter can be used instead to generate the value with customized Javascript code.
+% \end{description}
+% Currently the only supported backend is pdf\TeX.
+% \section{Example}
+% \begin{verbatim}
+% ...
+% \usepackage{hyperbar}
+% ...
+% \begin{document}
+% ...
+% \begin{Form}
+% \TextField[name=first,width=3cm,charsize=12pt]{Prename}\\
+% \TextField[name=last,width=3cm,charsize=12pt]{Name}\\
+% \BarcodeField[width=10cm,height=1cm,tsv={first,last}]{BarcodeField}\\
+% \BarcodeField[datamatrix,symwidth=10,width=3cm,height=3cm,tsv={first,last}]{BarcodeField2}\\
+% \BarcodeField[qr,width=3cm,height=3cm,tsv={first,last}]{BarcodeField3}
+% \end{Form}
+% \end{document}
+% \end{verbatim}
+% This example creates a simple PDF form. In PDF-Reader supporting Barcode fields three types of barcodes will be visible under the form, which contain the information entered into the fields.
