% \section{Documentation}
%
% \subsection{Introduction}
%
%            This is a very old package that I have written
%            to format phone numbers. It follows German
%            conventions and the documentation is mainly in German.
%
% \subsection{Short overview in English}
%
% \LaTeX:
% \begin{quote}
% |\usepackage{telprint}|\\
% |\telprint{123/456-789}|\\
% \end{quote}
% \plainTeX:
% \begin{quote}
%   |\input telprint.sty|\\
%   |\telprint{123/456-789}|
% \end{quote}
%
% \DescribeMacro\telprint
% |\telprint{...}| formats the explicitly given number.
%     Digits, spaces and some special characters
%     ('+', '/', '-', '(', ')', '\textasciitilde', ' ') are supported.
%     Numbers are divided into groups of two digits from the right.
% Examples:
% \begin{quote}
%     |\telprint{0761/12345}     ==> 07\,61/1\,23\,45|\\
%     |\telprint{01234/567-89}   ==> 0\,12\,34/5\,67\leavevmode\hbox{-}89|\\
%     |\telprint{+49 (6221) 297} ==> +49~(62\,21)~2\,97|
% \end{quote}
%
% \subsubsection{Configuration}
%
% The output of the symbols can be configured by
% \cs{telhyphen}, \cs{telslash}, \cs{telleftparen}, \cs{telrightparen},
% \cs{telplus}, \cs{teltilde}.
% Example:
% \begin{quote}
%   |\telslash{\,/\,}\\|
%   |\telprint{12/34} ==> 12\,/\,34|
% \end{quote}
%
% \DescribeMacro\telspace
% \cs{telspace} configures the space between digit groups.
%
% \DescribeMacro\telnumber
% \cs{telnumber} only formats a number in digit groups; special
%    characters are not recognized.
%
% \subsection{Documentation in German}
%
% \begin{otherlanguage*}{ngerman}
% \hyphenation{To-ken-ma-kros}
% \begin{itemize}
% \item \DescribeMacro\telprint |telprint#1|\\
%   Der eigentliche Anwenderbefehl zur formatierten Ausgabe von
%   Telefonnummern. Diese d\"urfen dabei nur als Zahlen angegeben
%   werden(, da sie tokenweise analysiert werden).
%   Als Trenn- oder Sonderzeichen werden unterst\"utzt:
%   '+', '/', '-', '(', ')', '\textasciitilde', ' '
%   Einfache Leerzeichen werden erkannt und durch Tilden ersetzt, um
%   Trennungen in der Telefonnummer zu verhindern. (Man beachte aus
%   gleichem Grunde die \cs{hbox} bei '-'.)
%   Beispiele:
%   \begin{quote}
%     |\telprint{0761/12345}     ==> 07\,61/1\,23\,45|\\
%     |\telprint{01234/567-89}   ==> 0\,12\,34/5\,67\leavevmode\hbox{-}89|\\
%     |\telprint{+49 (6221) 297} ==> +49~(62\,21)~2\,97|
%   \end{quote}
% \end{itemize}
% Der Rest enth\"alt eher Technisches:
% \begin{itemize}
% \item \DescribeMacro\telspace |\telspace#1|\\
%   Mit diesem Befehl wird der Abstand zwischen den Zifferngruppen
%   angegeben (Default: |\,|).
%   (Durch |\telspace{}| kann dieser zusaetzliche Abstand abgestellt
%   werden.)
% \item \DescribeMacro\telhyphen |\telhyphen#1|\\
%   Dieser Befehl gibt die Art des Bindestriches, wie er ausgegeben
%   werden soll. In der Eingabe darf jedoch nur der einfache
%   Bindestrich stehen:
%   |\telprint{123-45}|, jedoch NIE |\telprint{123--45}|!
%   Kopka-Bindestrich-Fans geben an:
%   |\telhyphen{\leavevmode\hbox{--}}|
% \item
%   \DescribeMacro{\telslash}
%   \DescribeMacro{\telleftparen}
%   \DescribeMacro{\telrightparen}
%   \DescribeMacro{\telplus}
%   \DescribeMacro{\teltilde}
%   |\telslash#1|, |\telleftparen#1|, |\telrightparen#1|, |\telplus#1|,
%   |\teltilde|\\
%   Diese Befehle konfigurieren die Zeichen '/', '(', ')', '+'
%   und '\textasciitilde'. Sie funktionieren analog zu \cs{telhyphen}.
% \item \DescribeMacro\telnumber |\telnumber#1|\\
%   Richtung interner Befehl: Er dient dazu, eine Zifferngruppe
%   in Zweiergruppen auszugeben.
%   Die einzelnen Zahlen werden im Tokenregister \cs{TELtoks}
%   gespeichert. Abwechselnd werden dabei zwischen zwei Token
%   (Zahlen) \cs{TELx} bzw. \cs{TELy} eingefuegt, abh\"angig von dem
%   wechselnden Wert von \cs{TELswitch}. Zum Schluss kann dann einfach
%   festgestellt werden ob die Nummer nun eine geradzahlige oder
%   ungeradzahlige Zahl von Ziffern aufwies. Dem entsprechend wird
%   \cs{TELx} mit dem Zusatzabstand belegt und \cs{TELy} leer definiert
%   oder umgekehrt. )
% \item |\TEL...| interne Befehle, Technisches:\\
%   \cs{TELsplit} dient zur Aufteilung einer zusammengesetzten
%   Telefonnummer (Vorwahl, Hauptnummer, Nebenstelle). In dieser
%   Implementation werden als Trennzeichen nur '/' und '-' erkannt.
%   Die einzelnen Bestandteile wie Vorwahl werden dann dem Befehl
%   \cs{telnumber} zur Formatierung uebergeben.
% \item Die Erkennung von einfachen Leerzeichen ist um einiges
%   schwieriger: Die Tokentrennung ueber Parameter |#1#2| funktioniert
%   nicht f\"ur einfache Leerzeichen, da TeX sie \emph{niemals} als
%   eigenst\"andige Argumente behandelt! (The TeXbook, Chapter 20,
%   p. 201)
%
%   (Anmerkung am Rande: Deshalb funktionieren die entsprechenden
%   Tokenmakros auf S. 149 des Buches "`Einf\"uhrung in TeX"' von
%   N. Schwarz (3. Aufl.) nicht, wenn im Tokenregister als erstes
%   ein einfaches Leerzeichen steht!)

% 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{telprint.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 telprint.dtx
%makeindex -s gind.ist telprint.idx
%pdflatex telprint.dtx
%makeindex -s gind.ist telprint.idx
%pdflatex telprint.dtx
%\end{verbatim}
