+%
+% \subsection{Introduction}
+%
+% In old code pages (CP 437, \dots) many slots are occupied
+% by graphical characters. The definition files for the input
+% encodings that come with \LaTeX's package \xpackage{inputenc}
+% ignore these characters. This packages tries to close this gap.
+% Package \xpackage{inputenx} provides more complete definitions
+% files of input encodings (\cite{inputenx}).
+%
+% The graphical characters are available in some fonts, mostly
+% some derivates of Courier. However, the symbols are usually
+% used to gegnerate some kind of ASCII art. Thus it should fit
+% with the current typewriter font in use. That means:
+% \begin{itemize}
+% \item Same and constant symbol width.
+% \item Use of the full line height. Vertical lines should not be
+%       interrupted if the symbols that contribute to that lines
+%       are in adjacent text lines.
+% \end{itemize}
+% Therefore I decided to generate the symbols by rules.
+% Parameters such as rule width and box dimensions are accessible
+% at macro level. This avoids to generate many fonts for the used
+% typewriter fonts (Courier, LuxiMono, Computer/Latin Modern, \dots).
+%
+% The disadvantage is that there are no characters in the output
+% file, just rules. Thus operations such as cut and paste or text
+% search will not detect these graphical characters.
+%
+% \subsection{Setup}
+%
+% Usually the box drawings symbols of this package derive its parameters
+% from the current font. But they can be set explicitly.
+%
+% \begin{declcs}{pmboxdrawbox} \M{template}
+% \end{declcs}
+% The \meta{template} is used as size template for the symbols.
+% It is initialized by |\strut0|. (Usually |\strut| carries the information
+% about the \cs{baselineskip} and |0| the symbol width.)
+%
+% \begin{declcs}{pmboxdrawrulewidth} \M{dimen}
+% \end{declcs}
+% This macro allows the setup of the rule width used in the symbols.
+% It is initialized with |0.1\width|, that means 10\,\% of the symbol
+% width. \cs{width}, \cs{height}, and \cs{depth} can be used here and
+% are set to the corresponding symbol box parameter.
+%
+% \begin{declcs}{pmboxdrawdoublerulesep} \M{dimen}
+% \end{declcs}
+% Some symbols have double lines. The distance between the lines is
+% configured by this macro. It is set to |0.25\width|, a quarter of
+% the symbol width. Also \cs{height} and \cs{depth} are available.
+%
+% \subsection{Symbol list}
+%
+% The macro names for the symbols in \LaTeX\ (LICR) are derived
+% from Adobe's glyph names for these characters (\cite{aglfn}).
+% Example:
+% \begin{quote}
+%   U+2580 (\textupblock) with glyph name \textsf{upblock}: \cs{textupblock}
+% \end{quote}
+% Some glyph names start with |SF|, two individual digits follow and
+% the name is closed by four digits zero. For the LICR name the
+% two individual digits form a number that is converted to lowercase
+% roman number. The trailing zeros are dropped. Example:
+% \begin{quote}
+%   U+2556 (\textSFxxi) with glyph name \textsf{SF210000}: \cs{textSFxxi}
+% \end{quote}
+%
+% The three gray symbols require package \xpackage{color}:
+% \begin{quote}
+%   U+2591 (\textltshade) light shade: \cs{textltshade}\\
+%   U+2592 (\textshade) medium shade: \cs{textshade}\\
+%   U+2593 (\textdkshade) dark shade: \cs{textdkshade}
+% \end{quote}
+%
+% It follows a list with all graphical symbols provided by this
+% package:

+%% \section{Installation}
+%
+% \subsection{Download}
+%
+% \paragraph{Package.} This package is available on
+% CTAN\footnote{\CTANpkg{pmboxdraw}}:
+% \begin{description}
+% \item[\CTAN{macros/latex/contrib/pmboxdraw/pmboxdraw.dtx}] The source file.
+% \item[\CTAN{macros/latex/contrib/pmboxdraw/pmboxdraw.pdf}] Documentation.
+% \end{description}
+%
+%
+% \paragraph{Bundle.} All the packages of the bundle `pmboxdraw'
+% are also available in a TDS compliant ZIP archive. There
+% the packages are already unpacked and the documentation files
+% are generated. The files and directories obey the TDS standard.
+% \begin{description}
+% \item[\CTANinstall{install/macros/latex/contrib/pmboxdraw.tds.zip}]
+% \end{description}
+% \emph{TDS} refers to the standard ``A Directory Structure
+% for \TeX\ Files'' (\CTANpkg{tds}). Directories
+% with \xfile{texmf} in their name are usually organized this way.
+%
+% \subsection{Bundle installation}
+%
+% \paragraph{Unpacking.} Unpack the \xfile{pmboxdraw.tds.zip} in the
+% TDS tree (also known as \xfile{texmf} tree) of your choice.
+% Example (linux):
+% \begin{quote}
+%   |unzip pmboxdraw.tds.zip -d ~/texmf|
+% \end{quote}
+%
+% \subsection{Package installation}
+%
+% \paragraph{Unpacking.} The \xfile{.dtx} file is a self-extracting
+% \docstrip\ archive. The files are extracted by running the
+% \xfile{.dtx} through \plainTeX:
+% \begin{quote}
+%   \verb|tex pmboxdraw.dtx|
+% \end{quote}
+%
+% \paragraph{TDS.} Now the different files must be moved into
+% the different directories in your installation TDS tree
+% (also known as \xfile{texmf} tree):
+% \begin{quote}

+% \end{quote}
+% If you have a \xfile{docstrip.cfg} that configures and enables \docstrip's
+% TDS installing feature, then some files can already be in the right
+% place, see the documentation of \docstrip.
+%
+% \subsection{Refresh file name databases}
+%
+% If your \TeX~distribution
+% (\TeX\,Live, \mikTeX, \dots) relies on file name databases, you must refresh
+% these. For example, \TeX\,Live\ users run \verb|texhash| or
+% \verb|mktexlsr|.
+%
+% \subsection{Some details for the interested}
+%
+% \paragraph{Unpacking with \LaTeX.}
+% The \xfile{.dtx} chooses its action depending on the format:
+% \begin{description}
+% \item[\plainTeX:] Run \docstrip\ and extract the files.
+% \item[\LaTeX:] Generate the documentation.
+% \end{description}
+% If you insist on using \LaTeX\ for \docstrip\ (really,
+% \docstrip\ does not need \LaTeX), then inform the autodetect routine
+% about your intention:
+% \begin{quote}
+%   \verb|latex \let\install=y\input{pmboxdraw.dtx}|
+% \end{quote}
+% Do not forget to quote the argument according to the demands
+% of your shell.
+%
+% \paragraph{Generating the documentation.}
+% You can use both the \xfile{.dtx} or the \xfile{.drv} to generate
+% the documentation. The process can be configured by the
+% configuration file \xfile{ltxdoc.cfg}. For instance, put this
+% line into this file, if you want to have A4 as paper format:
+% \begin{quote}
+%   \verb|\PassOptionsToClass{a4paper}{article}|
+% \end{quote}
+% An example follows how to generate the
+% documentation with pdf\LaTeX:
+% \begin{quote}
+%\begin{verbatim}
+%pdflatex pmboxdraw.dtx
+%makeindex -s gind.ist pmboxdraw.idx
+%pdflatex pmboxdraw.dtx
+%makeindex -s gind.ist pmboxdraw.idx
+%pdflatex pmboxdraw.dtx
+%\end{verbatim}
+% \end{quote}
