+		 dtk: A Document Class and Style for
+		      ``Die TeXnische Komoedie''
+
+			      written by
+			   Gerd Neugebauer
+		       gene@gerd-neugebauer.de
+
+
+dtk is a document  class and style file  which has been written  to be
+used for  the communications of  the German  speaking  TeX users group
+Dante e.V.: ``Die TeXnische Komoedie''.
+
+For changes from the previous versions see the end of this file.
+
+The  distribution consists of the  following  files (if one is missing
+then complain at the distributor of your version):
+
+dtk.dtx
+	This is the main distribution file. It contains the class and
+	style file. LaTeXing this file produces the English documentation. 
+dtk.ins
+	This is the driver file for the extraction procedure. You need
+	the doc utility to unpack it.
+dtk.bst
+	This is the BibTeX style file to be used for ``Die TeXnische
+	Komoedie''.
+Makefile
+	For those who are willing to take the risk:-)
+ReadMe
+	This file.
+beipiel.tex
+	A short description example for dtk (in German).
+beispiel.ltx
+	The driver file for beispiel.tex. Run this file through LaTeX to
+	get the dvi file.
+beispiel.bib
+	The bibliography for beispiel.tex.
+
+
+INSTALLATION
+------------
+
+(0)	If  you  have obtained  the  unpacked  distribution, i.e.  you
+	already have cls and clo files, then continue with step (2).
+
+(1)	Run TeX or LaTeX on dtk.ins.
+
+	This should produce the files  dtk.cls, dtk.sty, dtklogos.sty,
+	dtk.ist, and some dtk*.clo files.
+
+	This might fail due to several reasons. In this case revert to
+	the  unpacked files  which  are  also distributed at the  same
+	place where you got the sources from.
+
+(2)	Move  dtk.cls  and the dtk*.clo  files to a place  where LaTeX
+	searches for class files.  Move dtk.sty to a place where LaTeX
+	searches for style files.
+
+	The  suggested  place  for  the  LaTeX files  in a TDS conform
+	installation is the directory
+
+		TEXMF/tex/latex/supported/dtk
+
+	where TEXMF is the root of the TDS installation tree.
+
+(3)	Run LaTeX  on  dtk.dtx to  produce the documentation.  LaTeX2e
+	is required for this step.
+
+	Usually the  documentation contains a  general part describing
+	the  use  of  the  class/style  and  the  description  of  the
+	implementation details. If you want to omit the implementation
+	description you  can create the file  dtk.dcf before compiling
+	the  documentation.  This file  should  contain the  following
+	lines:
+
+		\OnlyDescription
+		\endinput
+
+(4)	Run LaTeX, BibTeX, and LaTeX twice again on beispiel.ltx for a
+	short description and a sample in German.
+
+
+CHANGES
+-------
+
+Version 1.8
+	Modifications for 2002:
+	Bibliography typeset raggedright.
+
+Version 1.7
+	Modifications for 2001
+ 
+Version 1.4 
+	Major changes to integrate all enhancements and patches since
+	the previous release.
+	Logos \NTS and \eTeX added.
+	New page dimensions.
+	dtklogos.sty as separate package.
+	dtk-pdf.sty and dtk.ist integrated.
+
+Version 1.3
+	Old layout variants moved to class option files.
+	Logos emTeX and PubliCTeX.
+	\part* acts like \part but appears like \chapter in the toc.
+	\RequiresPackage added to specify the needs of an article.
+
+Version 1.2
+	Logos for TeXXeT and TeXeT added.
+	\bibliographystyle{dtk} forced.
+
+Version 1.1
+	The bst file  had a minor problem  with  pages which  has been
+	fixed.
+	Titles are now typeset raggedright.  This is only relevant for
+	long titles. Those  can be broken manually  with \\.  For this
+	purpose  \\  is  ignored in  the   headline and  the  table of
+	contents.

+%    \begin{abstract}
+%
+%    dtk.dtx provides a class and style file for typesetting ``Die
+%    \TeX\-nische Ko\-m\"o\-die''---the communications of the German
+%    \TeX{} Users Group DANTE e.V. This means that this class can be
+%    used by article writers to typeset a single article as well as to
+%    produce the complete journal.
+%
+%    The class and style file is written in a way that it can be used
+%    both with \LaTeX\,2.09 and \LaTeXe. Thus it can be used by all
+%    persons which are familiar with any flavor of \LaTeX.
+%
+%    The features of \LaTeXe\ are provided in the \LaTeX\,2.09 mode only
+%    to a certain extend. Thus it might not be possible to typeset an
+%    article prepared for \LaTeXe\ with \LaTeX\,2.09.
+%
+%    On the other side it is possible to process an article prepared
+%    for \LaTeX\,2.09 with \LaTeXe{} (in native mode). This is justified
+%    since \LaTeXe{} is the standard nowadays and \LaTeX\,2.09 should
+%    cease to exists in the next decade.

+%
+%    \section{The History}
+%
+%    This documentclass/style is a complete reimplementation of a
+%    predecesor style. This predecessor style was a modification of
+%    the tugboat.sty which has been carried out mainly by Gabriele
+%    Kruljac. Some improvements have been made in this style by
+%    Joachim Schrod and Luzia Dietsche.
+%
+%    In 1995 the it appeared necessary to have a document class for the
+%    production of ``Die \TeX nische Kom\"odie''. Up to this time the
+%    communications of the German speaking \TeX{} users group had been
+%    typeset with \LaTeX\,2.09 which was already outdated at this
+%    time. In addition ideas for an improved layout had been collected
+%    which should be incorporated into the new class.
+%
+%    Thus Gerd Neugebauer started to derive a new class by modifying
+%    options and macros of the standard document class \texttt{article}. 
+%
+%    At this time it was not unususal for many installations not to
+%    provide the current \LaTeXe{} but still to have \LaTeX\,2.09
+%    only.  Thus one design decision was to have a document style as 
+%    well as a document class. The requirement was met by providing a
+%    set of definitions which emulate some of the new features of
+%    \LaTeX{} under the old releases.
+%
+%    The coding was done by Gerd Neugebauer but many influences of
+%    others have found their way into the code. Even so nearly no code
+%    has been taken from the predecessor style the layout has been
+%    copied in the first release of dtk.dtx (1.0).
+%
+%    Into the next releases (1.1 to 1.3) many changes for the new
+%    layout have been incorporated. Many suggestions of the editorial
+%    board of ``Die \TeX nische Kom\"odie'' had been integrated.
+%    Especially the following persons contributed during this process:
+%    Luzia Dietsche, Bernd Raichle, Volker RW Schaa, Rainer Sch\"opf,
+%    and Andreas Dafferner. 
+%
+%    Over the years several additions and corrections have made it
+%    into some additional packages which have been used for the
+%    production of ``Die \TeX nische Kom\"odie''. Especially in 1999
+%    the fonts have been changed from Computer Modern to EC. In 2000
+%    the text area has been changed. Finally all changes have been
+%    integrated into dtk.dtx. The contributions for this release came
+%    from Bernd Raichle, Peter Willardt, Rolf Niepraschk, and Werner
+%    Lemberg.
+%
+%    The 2002 edition of dtk.dtx includes some minor changes to
+%    support the use besides the production of ``Die \TeX nische
+%    Kom\"odie''. In addition the major change is that the
+%    bibliography is typeset in ragged right.

+%
+%    \section{The User Interface}
+%
+%    The user interface can be divided into two parts. The first part
+%    concerns the normal user who is writing a single article. The
+%    second part concerns the user who composes a complete journal.
+%
+%
+%    \subsection{The User Interface for Article Writers}
+%
+%    The user interface for ordinary users is mainly the interface as
+%    it is provided by the documentclass article. In addition to the
+%    normal commands the following macros and environments are defined:
+%
+%    \DescribeMacro{\address}
+%    This macro is used to put the address of an author into the list of
+%    authors. It should be given before the \verb|\maketitle| command. The
+%    first argument is the first name of an author. The second argument is the
+%    last name of the author. The third argument is it's address. Several
+%    lines in the address are separated by \verb|\\|. Missing arguments should
+%    be filled with \verb|\null|.
+%
+%    Several invocations of \verb|address| are possible. E.g. if the article
+%    has been written by several authors. The address and the author can be
+%    omitted completely --- e.g. for anonoymous letters to the editor.  But
+%    this should not be the normal case.
+%
+%    \DescribeEnv{abstract}
+%    Each article should have be started with a short paragraph describing
+%    what this article is about. This paragraph is called abstract. The
+%    environment \verb|abstract| is meant for marking a paragraph as
+%    abstract. 
+%
+%
+%
+%    The following restrictions should be taken into account:
+%
+%    The sectioning commands are mapped to their star variants.  This
+%    means that the commands like \verb|\section| are not numbered. It
+%    should not be tried to to put references to those commands.
+%
+%    The following logos are provided by this class and separately by
+%    the package \verb|dtklogos| if not defined somewhere else. You
+%    are strongly encouraged to use those macros to typeset the logos
+%    instead of making your own.

+%    \texttt{\char'134WinEdtKK}	&\WinEdtKK
+%    \end{tabular}
+%
+%    \DescribeMacro{\footnote}
+%    Footnotes are typeset in a special way. As a consequence of the
+%    inplementation \TeX{} is not allowed to split footnotes across
+%    several pages. Thus you have to keep your footnotes short. It is
+%    bad style to pack the main body of text into footnotes (except
+%    for critical editions).
+%
+%    \subsection{Logical Markup}
+%
+%    One of the advantages of \LaTeX\ is the possiblity to use logical
+%    markup. For this purpose several markup macros are provided.
+%    Unfortunately the macros provided are not sufficient in several
+%    situations. Thus this class provides some additional markup
+%    macros to come closer to the ideal situation.
+%    
+%    \DescribeMacro{\File}
+%    This macro is intended to be used for typesetting file names. 
+% 
+%    \DescribeMacro{\Package}
+%    This macro is intended to be used for typesetting package names. 
+% 
+%    \DescribeMacro{\Program}
+%    This macro is intended to be used for typesetting program names. 
+% 
+%    \DescribeMacro{\Command}
+%    This macro is intended to be used for typesetting command names.
+%    For instance command names are relevant when talking about Unix
+%    commands. 
+% 
+%    \DescribeMacro{\Macro}
+%    This macro is intended to be used for typesetting macro names.
+% 
+%    \DescribeMacro{\Environment}
+%    This macro is intended to be used for typesetting environment names.
+% 
+%    \DescribeMacro{\Email}
+%    This macro is intended to be used for typesetting email addresses.
+% 
+%    \DescribeMacro{\Acronym}
+%    This macro is intended to be used for typesetting acronyms. It is
+%    highly recommended to use this macro sparsingly
+%
+%
+%    \subsection{The Interface for the Production of the Whole Journal}
+%
+%    The first thing one needs to know is that a complete journal
+%    starts with a title page. This title page contains the volume,
+%    the number and the date of publication.  Since part of this
+%    information is used later it is stored in macros.
+%
+%    \DescribeMacro{\DieTeXnischeKomoedie}
+%    The macro \verb|\DieTeXnischeKomoedie| is provided for this purpose. It
+%    takes three arguments. The first argument is the number. The second
+%    argument is the annual set and the third argument is the publication
+%    date. 
+%
+%    \DescribeMacro{\CoverArt}
+%    The macro \verb|\DieTeXnischeKomoedie| calls the macro \verb|\CoverArt|
+%    to typeset the cover page. \verb|\CoverArt| gets the same three arguments
+%    as the calling macro \verb|\DieTeXnischeKomoedie|. This macro is
+%    responsible to fill the first page adequately. This maro might be
+%    redefined to alter the layout of the journal.
+%
+%    \DescribeMacro{\Label}
+%    The macro \verb|\label| has been redefined to be local for each
+%    article. Thus it turned out to be necessary to allow assigning of
+%    labels which are not restricted by this ``module system''. The
+%    macro \verb|\Label| sets such a global label.
+%
+%    \DescribeMacro{\Ref}
+%    The macro \verb|\ref| has been redefined to be local for each
+%    article. The macro \verb|\Ref| references a global label set with
+%    \verb|Label|.
+%
+%    \DescribeMacro{\Pageref}
+%    The macro \verb|\pageref| has been redefined to be local for each
+%    article. The macro \verb|\Pageref| references a global label set with
+%    \verb|Label|.
+%
+%    \DescribeMacro{\NeedPackage}
+%    Usually the article for the complete journal are stored in
+%    different files. If an article requires a package it has to be
+%    loaded in the preamble of the document. The macro
+%    \verb|\NeedPackage| provides a means to specify the required
+%    packages in the article files. Unfortunately \LaTeX{} does not
+%    provide a way to load missing packages in the document iyself
+%    thus the only reasonable action for this macros is to issue a
+%    warning message if a needed package is not found. Nevertheless
+%    this helps finding potential problems.

+%
+%    \subsection{The Interface for the Production of PDF Reprints}
+%
+%    A reprint of an article can be produced in PDF format. To
+%    accomplish this the package \texttt{dtk-pdf} is provided. This
+%    package makes provisions to produce an appropriate header and
+%    typeset the address information at the end.
+%
+%    To use the package you can use a driver file with the following
+%    structure: 
+%
+%    \begin{quote}
+%      \verb|\documentclass{dtk}|\\
+%      \texttt{\textit{preamble for article}}\\
+%      \verb|\usepackage{dtk-pdf}|\\
+%      \verb|\renewcommand\Volume{|\texttt{\textit{volume}}\verb|}|\\
+%      \verb|\renewcommand\Pages{|\texttt{\textit{pages}}\verb|}|\\
+%      \verb|\begin{document}|\\
+%      \verb|\input{|\texttt{\textit{tex\_file}}\verb|}|\\
+%      \verb|\Address|\\
+%      \verb|\end{document}|
+%    \end{quote}
+%
+%    Here \texttt{\textit{preamble for article}} should be replaced by
+%    the document preamble required for the production of the article.
+%    \texttt{\textit{volume}} is the volume of ``Die \TeX nische
+%    Kom\"odie'' in which the article has been published originally.
+%    \texttt{\textit{pages}} is the range of pages on which is has
+%    been published. Finally the article itself is included. This
+%    assumes that the article---without preamble---is contained in a
+%    file by its own.
+%
+%
+%
+%
+%
+%    \section{Notes on the Production of the Journal}
+%
+%    Several problems have to be solved for the production os the
+%    whole journal. This section collects some of them and shows which
+%    roads have been taken.
+%
+%    \subsection{References}
+%    References are done in \LaTeX\ with \verb|\label| and
+%    \verb|\ref|.  Since several articles are collected in the
+%    complete journal it may happen that the same label is used in
+%    different articles. To avoid name clashes the definitions of
+%    \verb|\label| and \verb|\ref| have been modified to prepend a
+%    unique prefix.
+%
+%    To enable you to make references across articles the original
+%    definitions of \verb|\label| and \verb|\ref|  have been saved in
+%    \verb|\Label| and \verb|\Ref| respectively.  
+%
+%
+%    \subsection{List of Authors}
+%    The list of authors is collected for the whole journal. This list
+%    is sorted alphabetically. To automate this process the names are
+%    written to the index file and makeindex is used to perform the
+%    sorting. Thus it is necessary for the complete journal to be run
+%    through \LaTeX, makeindex, and \LaTeX\ again.
+%
+%
+%    \subsection{Bibliography}
+%    The bibliography is prepared with \BibTeX. Since several articles
+%    are compiled we assume that the single articles are processed
+%    separately before. During this processing \BibTeX\ can be used to
+%    generate the appropriate bbl file.
+%    Things are arranged to include the bbl file for the article in
+%    question. 
+%
+%    One problem is not solved. This is the uniqueness of the \BibTeX\
+%    labels. Here manual invention is required.
+%

+%    \newenvironment{environment}[1]{}{}
+%    \fi
+%
+%
+%    \section{The Version Information}
+%
+%    The following lines define the version information for the class
+%    and the pdf package file. 
+%
+%    \begin{macrocode}
+%<*class|pdf|logos>
+\def\DTKrcs$#1: #2 #3${#2}

+\let\docversion=\fileversion
+\let\docdate=\filedate
+%</class|pdf|logos>
+%    \end{macrocode}
+%
+%
+%    \section{The Documentation Driver}
+%
+%    The documentation driver changes dtk.dtx into a self-extracting
+%    documentation.  Thus it is possible to run \LaTeX{} on dtk.dtx to
+%    produce the documentation.
+%
+%    The documentation can be adapted in a file named dtk.dcf
+%    (documentation configuration). This file can contain instructions
+%    for \verb|docstrip|. Especially useful might be the instruction 
+%
+%    \verb|\OnlyDescription|
+%
+%    which supresses the generation of the implementation description.
+%
+%    \changes{1.3}{1997/01/27}{The documentation driver has been
+%    integrated.}

+%
+%
+%    \section{The Implementation}
+%
+%
+%    The implementation is mainly based on existing styles/classes. This file
+%    contains only adaptions required to provide the logical markup
+%    and the definitions to get the special layout of ``Die \TeX
+%    nische Kom\"odie''.
+%
+%
+%    \subsection{Basic Definitions}
+%    
+%    \begin{macrocode}
+%<*class>
+%    \end{macrocode}
+%
+%     Now we need a boolean to see if we are in the author version or
+%     in the full version. The author version has several commands
+%     disabled. The full version is turned on by giving the option
+%     \verb|full| to the documentclass/style command.
+%
+%    \begin{macrocode}
+\newif\ifDTK@Author@
+\DTK@Author@true
+%    \end{macrocode}
+%
+%    The boolean \verb|DTK@german@| is used to determine if the german
+%    package should be loaded automatically. Usually it is turned on.
+%    Under certain circumstances it might be necessary to load other
+%    packages before the german package. Thus this variable can be set
+%    via a package option.
+%
+%    \begin{macrocode}
+\newif\ifDTK@german@
+\DTK@german@true
+%    \end{macrocode}
+%
+%
+%    \subsection{Compatibility Definitions}
+%
+%    Since we want to use this style with \LaTeX\,2.09 and \LaTeXe{} we have
+%    to define a common interface. For this purpose we use a subset of
+%    the style writers interface already defined for \LaTeXe{} style
+%    writers. Since some macros are not defined in \LaTeX\,2.09 we
+%    implement them --- at least to the degree needed here.
+%
+%    Starting with release 1.4 the backward compatibility may not work
+%    any longer. It will be eliminated in a future release.
+%
+%    \begin{macrocode}
+\ifx\documentclass\@undefined
+%    \end{macrocode}
+%
+%    \begin{macro}{\RequirePackage}
+%    The macro \verb|RequirePackage| simply tries to load the appropriate
+%    style file. The category code of \verb|@| is changed temporarily.
+%    The old value is is saved in \verb|\DTK@cat| and restored at the end.
+%    
+%    Optional arguments are not supported, yet.
+%
+%    \begin{macrocode}
+  \newcommand\RequirePackage[1]{
+    \chardef\DTK@cat=\the\catcode`\@
+    \catcode`\@=11
+    \input{#1.sty}%
+    \catcode`\@=\DTK@cat}
+%    \end{macrocode}
+%    \end{macro}
+%    
+%    \begin{macro}{\LoadClass}
+%    The concept of class and package files has not been so different in
+%    \LaTeX\,2.09. Thus the same that has been said for \verb|\RequirePackage|
+%    holds also for the macro \verb|\LoadClass|. Thus we just make it a
+%    synonym. 
+% 
+%    \begin{macrocode}
+  \let\LoadClass=\RequirePackage
+%    \end{macrocode}
+%    \end{macro}
+%    
+%    \begin{macro}{\InputIfFileExists}
+%    Now things get a little bit more complicated. To implement the
+%    macro \verb|\InputIfFileExists| we try to open the file. If this
+%    fails we assume that the file does not exist. The appropriate
+%    action is performed in both cases.
+% 
+%    \begin{macrocode}
+  \newcommand\InputIfFileExists[3]{%
+    \openin\DTK@file #1
+    \ifeof\DTK@file\closein\DTK@file #3%
+    \else\closein\DTK@file #2\input{#1}%
+    \fi}
+%    \end{macrocode}
+%    \end{macro}
+%
+%    \begin{macro}{\DeclareOption}
+%    The options in \LaTeX\,2.09 are defined as special named
+%    macros. This is emulated here. The star variant is simply mapped
+%    to do nothing.
+%    \begin{macrocode}
+  \newcommand\DeclareOption{\@ifstar{\@gobble}{\DTK@DeclareOption}}
+  \newcommand\DTK@DeclareOption[2]{\@namedef{ds@#1}{#2}}
+%    \end{macrocode}
+%    \end{macro}
+%
+%    \begin{macro}{\ProcessOptions}
+%    In \LaTeX\,2.09 the options are processed automatically. Thus
+%    this macro is simply a noop.
+%    \begin{macrocode}
+  \let\ProcessOptions=\relax
+%    \end{macrocode}
+%    \end{macro}
+%
+%    \begin{macro}{\OptionNotUsed}
+%    This feature is not present in \LaTeX\,2.09. Thus the argument is
+%    silently absorbed and the macro is simply a noop.
+%    \begin{macrocode}
+  \let\OptionNotUsed=\gobble
+%    \end{macrocode}
+%    \end{macro}
+%
+%    \begin{macro}{\ProvidesClass}
+%    This declaration is used to type out the version information.
+%    \begin{macrocode}
+  \def\ProvidesClass#1[#2]{\typeout{Document Style #1 #2}}
+%    \end{macrocode}
+%    \end{macro}
+%
+%    Just for fun we define some font switching commands. In fact the
+%    behaviour in \LaTeXe{} is more complex. But I think these
+%    definitions are enough to avoid errors.
+%    \begin{macrocode}
+  \newcommand\emph[1]{{\em #1}\/}
+  \newcommand\textbf[1]{{\bf #1}}
+  \newcommand\textrm[1]{{\rm #1}}
+  \newcommand\textsc[1]{{\sc #1}}
+  \newcommand\textsf[1]{{\sf #1}}
+  \newcommand\textsl[1]{{\sl #1\/}}
+  \newcommand\textit[1]{{\it #1\/}}
+  \newcommand\texttt[1]{{\tt #1}}
+
+  \@ifundefined{fontshape}{\let\fontshape=\@gobble}{}
+  \@ifundefined{selectfont}{\let\selectfont=\relax}{}
+
+  \newcommand\providescommand[2]{\ifx#1\@undefined\newcommand#1{#2}\fi}
+%    \end{macrocode}
+%
+%    \begin{macrocode}
+\fi
+%    \end{macrocode}
+%
+%    We need a new handle to read files. This handle will be used to
+%    implement \verb|\InputIfFileExists|. Since \verb|\newread| is
+%    declared \verb|\outer| we have to allocate the new handle here. It is
+%    just used in the \LaTeX\,2.09 mode.
+% 
+%    \begin{macrocode}
+\newread\DTK@file
+%    \end{macrocode}
+%
+%    Now we can continue without considering the \LaTeX{} dialect any
+%    more. Any changes we make from now on are exclusivly based on the
+%    interface defined above. 
+%
+%    This is all we had to do to implement the compatibility mode. It might
+%    turn out that more features are desirable. Those extensions are left to
+%    future versions of this class, eh sorry, style.
+%
+%
+%
+%    \subsection{Initializations}
+%
+%    
+%    Now we can start to define the class. The version date is taken
+%    from the macro \verb|\filedate|. This macro is defined at the
+%    beginning of this file. The value is changed by the version
+%    control system RCS.
+%    \changes{1.4}{2000/08/21}{File version added to class identifier.}
+%    \begin{macrocode}
+\ProvidesClass{dtk}[\filedate\space\fileversion\space  gene]
+%    \end{macrocode}
+%    
+%    The options to switch to other point sizes are disabled. Nobody
+%    is supposed to use this class with another than the single design
+%    size.
+%    \begin{macrocode}
+\DeclareOption{10pt}{\OptionNotUsed}
+\DeclareOption{11pt}{\OptionNotUsed}
+\DeclareOption{12pt}{\OptionNotUsed}
+%    \end{macrocode}
+%    
+%    The options to switch the oneside and twoside settings are
+%    disabled. Nobody is supposed to use this class with another than
+%    the single design size. 
+%    \begin{macrocode}
+\DeclareOption{twoside}{\OptionNotUsed}
+\DeclareOption{oneside}{\OptionNotUsed}
+%    \end{macrocode}
+%    
+%    We define an internal style option ``full''. This loads
+%    the multicolumn package from the Mainz distribution. It is only
+%    needed to produce the full journal. Additionally several macros
+%    are only defined in the full version. This makes sure that authors can
+%    not play with too much internal macros.
+%    \begin{macrocode}
+\DeclareOption{full}{\DTK@Author@false}
+%    \end{macrocode}
+%    
+%    The package option \verb|omitgerman| can be used to omit the
+%    loading of the package \verb|german.sty|. This migth be necessary
+%    if packages are required which have to be loaded before
+%    \verb|german|. 
+%    \begin{macrocode}
+\DeclareOption{omitgerman}{\DTK@german@false}
+%    \end{macrocode}
+%    
+%    In 1996 the layout of ``Die TeXnische Kom\"odie'' has been
+%    changed.  The option \verb|ancient| can be used to switch back to
+%    the old layout.
+%    \begin{macrocode}
+\DeclareOption{ancient}{\def\DTK@layout{95}}
+%    \end{macrocode}
+%

+%    \subsection{Loading the Used Packages/Styles}
+%
+%    This class is a variation of the \verb|book| class. Thus
+%    we load the base class. This loading is done with the macro from
+%    the interface definition or the built-in \LaTeXe{} primitive.
+%    \begin{macrocode}
+\LoadClass{book}
+%    \end{macrocode}
+%
+%    The T1 font encoding is used.

+%
+%    \begin{macrocode}
+\RequirePackage[T1]{fontenc}

+%
+%    For old issues of the journal the OT1 font encoding is used

+%
+%    The package ``\texttt{ngerman}'' is used since this class is
+%    intended to be used by german users mainly. As one result the
+%    language is set to german as default. On the other side some
+%    parameters are modified to get a layout according to german
+%    habits. E.g. fench spacing is activated.
+%
+%    There are some known problems when (n)german.sty is used. Therefore
+%    it might turn out necessary to load (n)german.sty after other
+%    packages have been loaded. For this purpose the option
+%    |omitgerman| can be used. To ensure proper operation of dtk it is
+%    necesary to call the macro \verb|\DTKgerman| after the style
+%    (n)german has been loaded.

+%    This macro can be used to declare in a single article which
+%    packages are required. At this places it is too late to load
+%    them if they are not loaded already. In stead a fat message is
+%    presented which warns the user of potential problems. 
+%
+%    This macro takes a single argument which is the name of
+%    \emph{one} package. Multiple packages and versions are not
+%    supported (yet).  
+%
+%    This macro is copied and modified from an \LaTeX2\ (june 1996)
+%    internal. It seems as \LaTeXe\ defines a control sequences for
+%    each package which is loaded. This mechanism is exploited.
+%
+%    Since older versions of \LaTeX\ do not support this mechanism
+%    warning are reported even so everything is ok.

+%
+%    \subsection{Layout Parameters}
+%
+%    The layout can be influenced by a large number of
+%    parameters.  Thus the design decisions have been made transparent
+%    (to a certain degree at least). These options are not meant to be
+%    changed except when a new layout is being designed and implemented.
+%
+%
+%    The size of the paper is A5. Thus the paper dimensions are defined
+%    appropriately.
+%    \begin{macrocode}
+\paperwidth  = 148.5mm
+\paperheight = 210mm
+%    \end{macrocode}
+%    \changes{1.4}{2000/08/06}{New page dimensions for 1/2000.}

+%    \begin{macrocode}
+\textheight = 471pt
+\textwidth  = 333pt
+%</class>
+%    \end{macrocode}
+%    The height is set to 484\,pt = 170.10654\,mm; the
+%    width is 342\,pt = 120.19925\,mm. This is slightly larger than in the
+%    predecessor style.

+%    \end{macrocode}
+%
+%    The page is flushed left. A left margin of one inch is the default
+%    on any properly installed printer. Any adjustment of the
+%    printable area on the page is left to the output driver.

+\oddsidemargin  = 0pt
+\evensidemargin = \oddsidemargin
+\topmargin      = 0pt
+%    \end{macrocode}
+%
+%    The head line needs some space. In fact this depends on some
+%    configurable macros. Nevertheless we take the old values and
+%    leave it to a user to change those values if required.
+%    \begin{macrocode}

+%
+%    Paragraphs are not indented but separated by additional lead
+%    only. This lead may expand a little bit but it may not
+%    shrink. (Since the whole journal is typeset with raggedbottom it
+%    is not clear to me if this makes sense at all)
+%    \begin{macrocode}
+\parskip   = 0.5\baselineskip \advance\parskip by 0pt plus 2pt
+\parindent = 0pt
+%    \end{macrocode}
+%
+%    To reduce the probability that a float requires a complete page
+%    we increase the allowed fraction which can be occupied by floats
+%    at the top and the bottom of the page. Additionally we reduce the
+%    fraction required for text.

+%    As promised before we disable vertical adjustment of pages. This

+%    special characters without inserting a hyphen.
+%
+%    Unfortunately this macro is fragile.

+%    \subsection{Logical Markup}
+%
+%    One of the advantages of \LaTeX\ is the possiblity to use logical
+%    markup. For this purpose several markup macros are provided.
+%    Unfortunately the macros provided are not sufficient in several
+%    situations. Thus this class provides some additional markup
+%    macros to come closer to the ideal situation.
+%    
+%    \begin{macro}{\File}
+%    This macro is intended to be used for typesetting file names.

+%
+%    \subsection{List Making Environments}
+%
+%    The list making environments \verb|description|, \verb|itemize|,
+%    and \verb|enumerate| are adapted to use less vertical space. This
+%    is mainly done by resetting \verb|\parsep|, \verb|\itemsep|, and
+%    \verb|\topsep|. 
+%
+%    The environments \verb|itemize| and \verb|enumerate| use the
+%    macros \verb|@listi|, \verb|@listii|, etc. Thus it is sufficient
+%    to redefine those macros.
+%
+%    \begin{macrocode}
+\def\@listI{%
+  \leftmargin = \leftmargini
+  \parsep     = \parskip
+  \topsep     = 0pt plus 2pt
+  \itemsep    = 0pt plus 2pt}
+%    \end{macrocode}
+%
+%    \begin{macrocode}
+\let\@listi=\@listI
+%    \end{macrocode}
+%
+%    \begin{macrocode}
+\def\@listii{%
+  \leftmargin = \leftmarginii
+  \labelwidth = \leftmarginii
+  \advance   \labelwidth by-\labelsep
+  \parsep     = \parskip
+  \topsep     = 0pt plus 2pt
+  \itemsep    = 0pt plus 2pt}
+%    \end{macrocode}
+%
+%    \begin{macrocode}
+\def\@listiii{%
+  \leftmargin = \leftmarginiii
+  \labelwidth = \leftmarginiii
+  \advance   \labelwidth by-\labelsep
+  \partopsep  = 1pt plus 0pt minus 1pt
+  \parsep     = \parskip
+  \topsep     = 0pt plus 2pt
+  \itemsep    = 0pt plus 2pt}
+%    \end{macrocode}
+%    We activate the defaults.
+%    \begin{macrocode}
+\@listi
+%    \end{macrocode}
+%
+%    For some reason \verb|@listi| is redefined in \verb|small| and
+%    \verb|\footnotesize|. Thus we have to take care to undo the
+%    changes made there. For this purpose we save the old definitions
+%    and restore the intended meaning of \verb|\@listi| after calling
+%    the old macro.
+%
+%
+%    \begin{macrocode}

+%<*class>
+%    \end{macrocode}
+%
+%    \begin{environment}{description}
+%    To get things smaller we completely redefine the description
+%    environment. Nevertheless we make use of the old label formatting
+%    macro.
+%    \begin{macrocode}
+\renewenvironment{description}{%
+  \begin{list}{}{%

+%    \end{macro}
+%
+%    \begin{environment}{quotation}
+%    Since the whole journal does not use parindent we make the
+%    quotation environment the same as the quote environment.
+%    \begin{macrocode}
+\renewenvironment{quotation}{%
+  \list{}{\rightmargin\leftmargin}%
+  \item\relax
+}{\endlist}

+%</ninetyfive>
+%<*class>
+%    \end{macrocode}
+%    \end{environment}
+%
+%    \begin{environment}{roll}
+%    We add a new type of list making environment. The \verb|roll|
+%    does not indent per default but just typesets the argument of the
+%    \verb|\item| macro in boldface. It has one optional argument
+%    which can be used to specify the amount of indentation desired.
+%    
+%    \begin{macrocode}
+\newenvironment{roll}%
+  {\@ifnextchar[{\r@ll}{\r@ll[0pt]}}%
+  {\end{list}}

+    \itemsep    = .3ex
+    \let\makelabel=\rolllabel}%
+  }
+%    \end{macrocode}
+%    \end{environment}
+%
+%    Typeset the label of a \verb|roll| environment.
+%    \begin{macrocode}
+\newcommand\rolllabel[1]{\hspace\labelsep \textbf{#1}\hfill}
+%    \end{macrocode}
+%
+%
+%    \begin{environment}{example}
+%    We provide an environment for typesetting example code.
+%    It is typeset in a smaller font with an indentation left and right.
+%    \begin{macrocode}
+\newenvironment{example}{\begin{quote}\small}{\end{quote}}
+%    \end{macrocode}
+%    \end{environment}

+%
+%    \subsection{Sectioning Commands}
+%
+%
+%    The counter \verb|secnumdepth| determines which sectional units
+%    are decorated with a number. Since we don't want sections and
+%    everything below to be numbered we set this counter to 0.
+%    \begin{macrocode}
+\setcounter{secnumdepth}{0}
+%    \end{macrocode}
+%
+%    All but the first article are separated by additional vertical
+%    space from the preceding text. Thus we define a new boolean
+%    variable to determine which article is the first one in a chapter.
+%    \begin{macrocode}
+\newif\ifFirstArticle
+\FirstArticletrue
+%    \end{macrocode}
+%
+%    \begin{macro}{\part}
+%    This definition is used in the author version, where \verb|\part|
+%    should not be used. An error message is issued instead.
+%    \begin{macrocode}
+\ifDTK@Author@
+  \renewcommand\part{%
+    \typeout{*** Parts can not be used in single articles.}}
+\else
+%    \end{macrocode}
+%
+%    A part is aligned to the next full page. A special page style is
+%    used on a first page of a part. The macro \verb|\part| has one
+%    ordinary argument which constitutes the main title of the part.
+%    This argument can be preceeded by an optional argument---enclosed
+%    in brackets. This first optional argument is used as the running
+%    head. If it is missing the main title is used instead.
+%
+%    The main argument can be followed by another optional argument.
+%    This second optional argument is the subtitle of the part.
+%    If none is given then the empty default is used instead.
+%    The second optional argument is an enhancement compared to the
+%    original definition of parts in \LaTeX. 
+%
+%    \begin{macrocode}
+  \renewcommand\part{%
+    \clearpage

+\fi
+%    \end{macrocode}
+%    \end{macro}
+%
+%    \begin{macro}{\part@star}
+%    If the next character is a \verb|[| then the part macro has an
+%    optional argument.

+%
+%    \begin{macro}{\part@optional}
+%    This macro treats the case that the part macro has an optional

+%
+%    \begin{macro}{\part@normal}
+%    This macro treats the case that the part has no optional
+%    argument.  In this case the title itself is used in the head and
+%    in the table of contents.

+%    \end{macro}
+%
+%    \begin{macro}{\TopArt}
+%    This macro is used to generate the layout of the beginning of a

+%    the part and the second argument is its subtitle. If the subtitle
+%    is not empty then it is started by \verb|\\|.

+%    \subsection{The Article Layout}
+%
+%
+%    \begin{macro}{\keywords}
+%    The macro \verb|keywords| is intended for the user to specify
+%    keywords for the article. It is not used for the article itself
+%    but for the reprint and the \BibTeX\ file of all articles.
+%    \begin{macrocode}
+\newcommand\keywords[1]{\def\DTK@keywords{#1}}
+\def\DTK@keywords{}
+%    \end{macrocode}
+%    \end{macro}
+%
+%    \begin{macro}{\maketitle}
+%    The title of an article is typeset together with the author
+%    information.  If it is the first article in this chapter then
+%    additional vertical space is added.
+%
+%    The title is added to the table of contents and the headline is
+%    adjusted appropriately.
+%
+%    The macro \verb|\NewpageThreshold| is used to determine how much
+%    space is needed aon a page to start a new article. If less space
+%    is left then the next article is started on the next page.
+%
+%    Now we can start to typeset the head of an article and perform
+%    all tasks required in this situation.
+%
+%    \begin{macrocode}
+\renewcommand\maketitle{%
+%    \end{macrocode}
+%
+%    If we are not in a complete journal then we use a different page style
+%    for the first page. Thus it is possible to use this class to typeset
+%    preprints and get a better layout of the first page.
+%    \begin{macrocode}
+  \ifDTK@Author@ \thispagestyle{part}\fi
+%    \end{macrocode}
+%
+%    Now we have to ensure that there is enough space left on this page to
+%    start a new article. If there isn't enough space we start the article on
+%    the next page.
+%    \changes{1.5}{2001/04/25}{Bugfix: constant replaced by macro.}

+%    \end{macrocode}
+%
+%    The namespace for labels has to be switched. This is done by
+%    calling the macro \verb|\Advance@Label@Prefix|.
+%    \begin{macrocode}
+  \Advance@Label@Prefix
+%    \end{macrocode}
+%
+%    We encapsulate the title and author information in a minipage to avoid a
+%    pagebreak in beween (maybe not necessary). Then we draw a line to
+%    separate the article from the previous one. The line is required if the
+%    boolean variable \verb|FirstArticle| is true. This variable is set
+%    afterwards.

+%
+%    \subsection{Numbering}
+%    
+%    The numbering is done on a global basis. No chapter numbers are
+%    prepended. Especially since none are used at all. This is just
+%    like in the article class.
+%
+%    \begin{macrocode}
+\renewcommand\thefigure{\arabic{figure}}

+%    \end{macrocode}
+%
+%
+%    \subsection{Labels}
+%    
+%    Labels have to be used on an per article basis for this purpose
+%    we use a macro to hold the prefix for the labels. This prefix is
+%    prepended whenever something is done with the labels.
+%
+%    The prefix is constructed from a numeric counter. This counter is%    allocated and initialized. Maybe I could live without this
+%    counter but this way the labels look nicer (if you ever see them).
+%    \begin{macrocode}
+\newcount\DTL@label
+\DTL@label=0
+%    \end{macrocode}
+%
+%    \begin{macro}{\Advance@Label@Prefix}
+%    This macro is expanded whenever a new module is entered. It has
+%    to take care that a new and unique prefix string for the labels
+%    is generated and stored in the macro \verb|\Label@Prefix|.
+%    \begin{macrocode}
+\newcommand\Advance@Label@Prefix{%
+  \advance\DTL@label 1
+  \xdef\Label@Prefix{module \the\DTL@label:}}
+%    \end{macrocode}
+%    \end{macro}
+%
+%    The label prefix has to be initalized. The easiest way to perform
+%    this task is touse the macro defined above.
+%    \begin{macrocode}
+\Advance@Label@Prefix
+%    \end{macrocode}
+%
+%    Sometimes it is desirable to use labels in the old
+%    sense. I.e. without the module system. For this purpose we keep
+%    the old definitions of the macros \verb|\ref|, \verb|\label|, and
+%    \verb|\pageref| under the new names \verb|\Ref|, \verb|\Label|, and
+%    \verb|\Pageref| respectivly.
+%    \begin{macrocode}
+\let\Ref=\ref
+\let\Label=\label
+\let\Pageref=\pageref
+%    \end{macrocode}
+% 
+%    \begin{macro}{\ref}
+%    The module prefix is prepended before the original \verb|\ref|
+%    macros is used.
+%    \begin{macrocode}
+\renewcommand\ref[1]{\Ref{\Label@Prefix:#1}}
+%    \end{macrocode}
+%    \end{macro}
+% 
+%    \begin{macro}{\label}
+%    The module prefix is prepended before the original \verb|\label|
+%    macros is used.
+%    \begin{macrocode}
+\renewcommand\label[1]{\Label{\Label@Prefix:#1}}
+%    \end{macrocode}

+%    \subsection{Defining Page Styles}
+%
+%    \subsubsection{The Page Style ``plain''}
+%
+%    The page style plain provides a head line and a foot line.  The
+%    page number is printed in the outer corner of the head line.  The
+%    inner part of the head line contains the title of the current
+%    article. 
+%
+%    The foot line contains the name and number of the current journal
+%    flushed towards the inner border of the page.
+%
+%    The head line and the footline are separated by a bar from the
+%    main body of text.
+%
+%    \begin{macrocode}

+% 
+%    \subsubsection{The Page Style ``part''}
+% 
+%    The page style \verb|part| contains the same foot as the page style
+%    \verb|plain|. The head line is empty.
+% 
+%    This style is used when a new part is started. It can be
+%    configured by redefining the macros \verb|FootRuleDepth|,
+%    \verb|\FootFont|, and \verb|\PagenoFont|.
+%

+%    \end{macrocode}
+% 
+%    The default page style is plain. This has been set by the book
+%    style before. If we want our changes to take effect we have to
+%    reinitialize the page style.

+%    \subsection{List of Addresses}
+%
+%    Addresses can be given anywhere throughout the whole
+%    document. The address together with the page where it has been
+%    given is stored in the index.
+% 
+%    The list of addresses is handled by the index mechanism of
+%    \LaTeX.  I (safely) assume that nobody has the desire to make an
+%    index for a journal.
+%
+%    \begin{macro}{\address}
+%    The address macro takes three arguments. The first argument is the
+%    first name the second is the last name and the third is the
+%    address where several lines can be included which are separated
+%    by \verb|\\|. 
+%
+%    The macro can be e.g. as follows:\\
+%    \verb|\address{Gerd}{Neugebauer}%|\\
+%    \verb|        {Mainzer Str. 8\\56321 Rhens}|
+%
+%
+%    The address is given to \verb|\index| to be stored in the .idx
+%    file. This file is sorted and reformatted to produce the sorted
+%    list of addresses.
+%
+%    The problem was to get the correct (German) ordering. For this
+%    purpose the \TeX{} macros which  are (normally) part of a name
+%    have to be expanded properly. Unfortunately plain expansion may
+%    leave braces which confuse makeindex. To get rid of these braces
+%    we have to scan the tokens and transfer those tokens that are not
+%    braces. 
+%
+%    We use one big assumption. We assume that a name does not contain
+%    a dollar sign. Well, it is rather unusual that mathematics is
+%    part of a name.
+%
+%    The better solution would be a future version of makeindex which
+%    is able to cope with those problems (wait and pray:-)

+%
+%    First we have to determine which kind of \LaTeX{} is running. We use
+%    the existence of the macro \verb|\documentclass| to see if we have a
+%    \LaTeXe. This macro should not be defined in \LaTeX\,2.09.
+%    \begin{macrocode}
+\newif\ifOldLaTeX
+\@ifundefined{documentclass}{\OldLaTeXtrue}{\OldLaTeXfalse}
+%    \end{macrocode}
+%    The following hack is from Bernd Raichle.
+%
+%    For \LaTeX\,2.09 (with or without NFSS) we need something like
+%    the \verb|\smaller| from the obsolete ``smaller.sty'' to emulate
+%    SmallCaps for (nearly) all types of fonts. For SmallCaps it is
+%    required to reduce further than for \verb|\smaller|. Thus we make
+%    a new definition for \verb|\logo@smaller| which is oriented at
+%    the ``math sizes'' (here: \verb|\scriptfont<fam>|) which is
+%    defined in \LaTeXe.
+%
+%    \begin{macrocode}
+\ifOldLaTeX
+\expandafter\ifx\csname selectfont\endcsname\relax
+%    \end{macrocode}
+%
+%   For OFSS a hack is needed to switch back to Family/Series/Shape.
+%   For this purpose we ``abuse'' the ``math group/fam'' which is
+%   changed similar to the macros from the file ``lfonts.tex''.
+%    \begin{macrocode}
+  \newcommand{\logo@sm@ller}{\relax
+    \expandafter\logo@sm@ll@r\expandafter{\the\fam}}
+  \newcommand{\logo@sm@ll@r}[1]{%
+    % \ifx\@currsize\tiny \tiny\fi
+    \ifx\@currsize\scriptsize \tiny\fi
+    \ifx\@currsize\footnotesize \tiny\fi
+    \ifx\@currsize\small \scriptsize\fi

+\else
+%    \end{macrocode}
+%
+%   With NFSS (for \LaTeX\,2.09) we can change the size indepenently
+%   from the other font properties. Thus things are easier.
+%    \begin{macrocode}

+%    The following macros are taken from the file {\tt texnames.sty}
+%    version \verb|1.09| from \verb|<16 March 1993>| by Nelson
+%    H.\,F.~Beebe. I have simply included the definitions here to avoid

+%    documentation has been wrapped into the doc format. And here it goes:
+%
+%    In the following, we first give the ``official'' definition,
+%    then follow it with spelling variants.  Alternate definitions
+%    are discarded in favor of the official one.  Each family is
+%    separated by a line like the following one.
+%   
+%    \begin{macro}{\TeX}
+%    Only change from plain.tex is the \verb|\spacefactor| assignment

+%    \changes{1.4}{2000/08/27}{Index file integrated into the dtx file.}
+%
+%    The index style is used to sort the authors of the journal for
+%    the list of all authors. Makeindex is used for this purpose. Here
+%    we have to define the appropriate configuration file.
+%
+%    \begin{macrocode}
+%<*ist>
+actual '*'
+preamble  "\\begin{theaddresses}"
+postamble "\n\\end{theaddresses}\n"
+item_0 "\n  \\addressitem{"
+item_2 "}{"
+item_x1 "}{"
+item_x2 "}{"
+delim_0 "}{"
+delim_1 "}{"
+delim_2 "}{"
+delim_t "}"
+group_skip ""
+quote '$'
+%</ist>
+%    \end{macrocode}
+%
+%    That's all.
