+%
+% \section{The Expanded \texttt{description} Environment}
+% The expanded \texttt{description} environment supports an easy
+% possibility of changing the left margin in a \texttt{desciption list}.
+% The text of the item begins at the left margin, either behind the label
+% or in the following line.
+% Another declaration eliminates the vertical space which is set by the
+% \LaTeX-\texttt{STY}s.
+% As well you can affect the appearance of the label.
+% The syntax of the expanded \texttt{description} environment is:
+% \begin{quote}
+% \verb+\begin{description}[+\textit{declarations}\texttt{]}\\
+% $\vdots$\\
+% \verb+\end{description}+
+% \end{quote}
+% Without the optional \textit{declarations} this environment is equal to
+% the original \LaTeX-\texttt{description} environment.
+%
+% \newpage
+% \noindent
+% The following declarations fix the left margin of the item:
+% \begin{description}[\setlabelstyle{\ttfamily} \setleftmargin{3cm} \breaklabel
+%                     \compact]
+% \item[\ttbackslash setleftmargin\ttlbrace \textnormal{\textit{size}}\ttrbrace]
+%                         gives the amount of horizontal
+% \SpecialUsageIndex{\setleftmargin}
+%                         space to be reserved
+%                         for the left margin of the item,
+%                         and defaults to the value of the original
+%                         \LaTeX-\texttt{description} list if not entered.
+% \item[\ttbackslash setlabelphantom\ttlbrace \textnormal{\textit{text}}\ttrbrace]
+%                         calculates the left margin by the width of
+% \SpecialUsageIndex{\setlabelphantom}
+%                         \textit{text} and by the value of \verb+\labelsep+.
+%                         The setting of \verb+\setlabelstyle+ is taken
+%                         into account.
+% \listpart{If you set \texttt{\ttbackslash setlabelphantom}
+%                         as well as \texttt{\ttbackslash setleftmargin}, the
+%                         horizontal space with the width defined by
+%                         \texttt{\ttbackslash setlabelphantom} will be
+%                         reserved.}
+% \listpart{There are some other declarations affecting the layout of the
+%           expanded \texttt{description} list:}
+% \item[\ttbackslash breaklabel]
+%                         causes the definition description to start on
+% \SpecialUsageIndex{\breaklabel}
+%                         the line following the label if the width of
+%                         the label exceeds the width of the left
+%                         margin. The default is to
+%                         begin the description
+%                         on the same line after the label.
+% \item[\ttbackslash compact]
+%                         indicates that items should not be
+% \SpecialUsageIndex{\compact}
+%                         separated from each other by vertical white
+%                         space.
+% \item[\ttbackslash setlabelstyle\ttlbrace \textnormal{\textit{typestyle}}\ttrbrace]
+%                         identifies the style to be
+% \SpecialUsageIndex{\setlabelstyle}
+%                         used for labels, e.\,g. \verb+\bfseries+,
+%                         \verb+\itshape+, \verb+\slshape+ or \verb+\sffamily+
+%                         as well as \verb+\small+, \verb+\large+, etc.
+%                         The default is \verb+\bfseries+ and \verb+\normalsize+.

+% \noindent
+% The following examples demonstrate some features of the expanded
+% \linebreak \texttt{description} environment.\\[4ex]
+% The first example shows it without optional parameters being equal
+% to the original \LaTeX\ environment.
+% The command used is:\\[-4ex]

+% \section{The \texttt{\char92 listpart} command}
+% In the \texttt{EXPDLIST} style there are two new \LaTeX\ commands:
+% \begin{description}[\setlabelstyle{\ttfamily} \setleftmargin{3cm} \breaklabel
+%                     \compact]
+% \item[\ttbackslash listpart\ttlbrace \textnormal{\textit{text}}\ttrbrace]
+%                         identifies a comment or explanation that
+% \SpecialUsageIndex{\listpart}
+%                         applies to a part of a list.
+%                         It can be placed anywhere
+%                         within any \texttt{list} environment,
+%                         immediately preceeding
+%                         those items to which it applies.
+%                         The width of \textit{text} depends on the width
+%                         of the preceeding list. Therefore you are able
+%                         to continue with the next item without
+%                         closing and re-opening the list. The numbering
+%                         of the \texttt{enumerate} environment is preserved.
+% \item[\ttbackslash listpartsep]
+%                         is the vertical space between the item and
+% \SpecialUsageIndex{\listpartsep}
+%                         the comment produced by
+%                         \texttt{\ttbackslash listpart}.
+%                         It defaults to \texttt{1ex}.
+% \end{description}
+% The following example demonstrates that you can use \verb+\listpart+
+% also in multi-clause \texttt{list} environments:
+% \begin{quote}
+% \begin{itemize}
+% \item You can use \verb+\listpart+ in multi-clause environments.
+% \listpart{This is a \texttt{listpart} which puts in some text to
+%           interrupt the list.}
+% \item You can use \verb+\listpart+ in
+% \begin{enumerate}
+% \item{\texttt{itemize}-lists}
+% \item{\texttt{enumerate}-lists}
+% \listpart{This is a \texttt{listpart} which puts in some text to
+%           interrupt the list.}
+% \item{\texttt{description}-lists:}
+% \begin{description}[\setleftmargin{60pt}]
+% \item[1st Label] Description A
+% \listpart{This is a \texttt{listpart} which puts in some text to
+%           interrupt the list.}
+% \item[2nd Label] Description B

+% \changes{V 2.0}{17.05.90}{Documentation with the \texttt{DOC.STY}}
+% \section{The description of the \texttt{EXPDLIST.STY}-file}
+% \subsection{The beginning}
+% Here is a description of the macros used in the \texttt{EXPDLIST.STY}.
+% We started by defining the current version and date of this file and
+% documentation:
+%\iffalse
+%<*style>
+%\fi
+%    \begin{macrocode}
+\typeout{Document Substyle `EXPDLIST'.
+         Released \filedate \space (\fileversion)}
+\typeout{English Documentation \space \docdate}
+%    \end{macrocode}
+% \subsection{The optional arguments}
+% \begin{macro}{\compact}
+% The first implemented macro is \verb+\compact+. Normally two items
+% are separated by a blank line. This blank line is defined in \LaTeX\
+% by \verb+\itemsep+ \texttt{+} \verb+\parsep+. To remove this blank line
+% we defined
+%    \begin{macrocode}
+\def\compact%
+   {\setlength{\itemsep}{-\parsep}}
+%    \end{macrocode}
+% \end{macro}
+% \par
+% \begin{macro}{\setleftmargin}
+% \begin{macro}{\setlabelsize}
+% To define \verb+\setleftmargin+ we assigned the new width
+% to \verb+\leftmargin+:
+%    \begin{macrocode}
+\def\setleftmargin%
+   #1%
+   {\setlength{\leftmargin}{#1}}
+%    \end{macrocode}
+% The \texttt{\ttbackslash setleftmargin} command was named
+% \texttt{\ttbackslash setlabelsize} in older versions. To be compatible with
+% these versions the old command is also defined:
+%    \begin{macrocode}
+\let\setlabelsize = \setleftmargin
+%    \end{macrocode}
+% \end{macro}
+% \end{macro}
+% \changes{V 2.0}{17.05.90}{Change of \texttt{\ttbackslash setleftmargin}}
+% \par
+% \begin{macro}{\setlabelphantom}
+% The \verb+\setlabelphantom+ command reserves the width of the argument
+% as horizontal space for the label. We have to put a \verb+\hfil+ into
+% \verb+\@tempboxa+ to avoid an \texttt{underful hbox} message because the
+% box is wider than the argument by the value of \verb+\labelsep+.
+% The width is stored in  \verb+\setleftmargin+.
+%    \begin{macrocode}
+\def\setlabelphantom%
+   #1%
+   {\def\set@labelphantom%
+     {\setbox\@tempboxa=\hbox spread \labelsep {\@labelstyle #1\hfil}%
+      \setleftmargin{\wd\@tempboxa}%
+     }%
+   }
+\def\set@labelphantom{}
+%    \end{macrocode}
+% \end{macro}
+% \changes{V 1.2}{09.05.90}{Change of \texttt{\ttbackslash hfil}}
+% \par
+% \begin{macro}{\setlabelstyle}
+% The \verb+\setlabelstyle+ identifies the style to be used for labels.
+% In \verb+\@labelstyle+ the default \verb+\bfseries+ is stored.
+%    \begin{macrocode}
+\def\@labelstyle%
+   {\bfseries}
+\def\setlabelstyle%
+   #1%
+   {\def\@labelstyle{#1}}
+%    \end{macrocode}
+% \end{macro}
+% \par
+% \begin{macro}{\breaklabel}
+% To let work \verb+\breaklabel+ correctly as described before we need
+% a rule with no dimension in the \verb+\item+ definition of \LaTeX.
+% This rule is defined here:
+%    \begin{macrocode}
+\def\breaklabel%
+   {\def\@breaklabel%
+       {\rule{0mm}{0mm}%
+        \\%
+       }%
+   }%
+\def\@breaklabel%
+   {}
+%    \end{macrocode}
+% \changes{V 1.1}{26.03.90}{Change of \texttt{\ttbackslash breaklabel}}
+% The changed \verb+\item+ definition follows a little later.
+% \end{macro}
+% \subsection{The main macro}
+% \begin{macro}{\description}
+% \begin{macro}{\enddescription}
+% Now we can begin with the new \verb+\description+ definition (which is
+% in \LaTeX\ the same as \verb+\begin{description}+).
+% First we had to rename \verb+\description+ to
+% \verb+\@orgdlist+. It will be executed if no optional argument is set:
+% \par
+%    \begin{macrocode}
+\let\@orgdlist\description
+%    \end{macrocode}
+% \changes{V 2.1}{13.08.92}{Change of \texttt{\ttbackslash @orgdlist}}
+% We must look
+% if there is an optional argument. If there is an optional
+% argument the macro \verb+\@expdlist+ (our new macro) will be
+% executed. Otherwise the original \LaTeX-macro will be executed which
+% we have renamed to \verb+\@orgdlist+:
+%    \begin{macrocode}
+\def\description%
+   {\@ifnextchar[%
+       {\@expdlist}%
+       {\@orgdlist}%
+   }
+\let\enddescription\endlist
+%    \end{macrocode}
+% \end{macro} ^^A of \enddescription
+% \end{macro} ^^A of \description
+% \par
+% We had to rename \verb+\description+ to
+% \verb+\@orgdlist+. It will be executed if no optional argument is set:
+% \par
+% If you have set any optional argument, the \verb+\@expdlist+
+% definition will be executed.
+%    \begin{macrocode}
+\def\@expdlistlabel#1%
+    {\@labelstyle
+     #1%
+     \hfil%
+    }
+\def\@expdlist[#1]%
+    {\list{}%
+      {\def\@breaklabel{}%
+       \def\set@labelphantom{}%
+       \def\@labelstyle{\bfseries}%
+       #1%
+       \set@labelphantom%
+       \setlength{\labelwidth}{\leftmargin}%
+       \addtolength{\labelwidth}{-\labelsep}%
+       \let\makelabel\@expdlistlabel%
+      }%
+    }
+%    \end{macrocode}
+% \changes{V 1.1}{26.03.90}{Change of \texttt{\ttbackslash breaklabel}}
+% \changes{V 1.2}{09.05.90}{Change of \texttt{\ttbackslash hfil}}
+% \subsection{\texttt{\ttbackslash listpart} and
+%                 \texttt{\ttbackslash listpartsep}}
+% \begin{macro}{\listpartsep}
+% Another feature of the \texttt{EXPDLIST.STY} is \verb+\listpart+. To
+% adjust the vertical space between the item and the comment produced
+% by \verb+\listpart+ we had to define a new measure named
+% \verb+\listpartsep+.
+%    \begin{macrocode}
+\newlength{\listpartsep}
+\listpartsep = 1ex
+%    \end{macrocode}
+% \end{macro}
+% \begin{macro}{\listpart}
+% Now we could define \verb+\listpart+ as a long definition, because

+% \subsection{The redefinition of \texttt{\ttbackslash \@item}}
+% \begin{macro}{\@item}
+% To let work \verb+\breaklabel+ correctly we had to redefine the
+% original \LaTeX\ de\-fi\-ni\-tion of \verb+\@item+ in a few lines
+% (see \texttt{RUM Change} marks). We had to
+% define \verb+\set@break+ globally, because it is set within a
+% \verb+\hbox+, but used outside.
+% Depending on the width of the label text \verb+\set@break+ is set to
+% \verb+\@breaklabel+ or to nothing.
+% At the end of the \verb+\@item+ macro \texttt{\ttbackslash set\@break}
+%  is called after the label is set.

+% \begin{description}[\compact\setlabelphantom{V 8.8 (88.88.8888)M}]
+% \item[V 1.0 (02.03.1990)] First published Version (H\"ulse and Kaspar)
+% \item[V 1.1 (26.03.1990)] We had to change \texttt{\ttbackslash break} to
+%                           \texttt{\ttbackslash breaklabel} and
+%                           \texttt{\ttbackslash @break} to
+%                           \texttt{\ttbackslash @breaklabel}
+%                           because \texttt{\ttbackslash break}
+%                           is a \TeX-primitive. This could cause
+%                           difficulties with linebreaking. (H\"ulse)
+% \item[V 1.2 (09.05.1990)] To be more flexible with the label, we changed
+%                           \texttt{\ttbackslash hfill} to
+%                           \texttt{\ttbackslash hfil}
+%                            in \texttt{\ttbackslash @expdlistlabel} (H\"ulse)
+% \item[V 2.0 (31.05.1990)] Documentation with the \texttt{DOC.STY} from Frank
+%                           Mittelbach, University of Mainz,
+%                           FRG.\newline
+%                           \texttt{\ttbackslash setlabelsize}
+%                            will be renamed to
+%                           \texttt{\ttbackslash setleftmargin}
+%                           (H\"ulse)
+% \item[V 2.1 (13.08.1992)] \texttt{\ttbackslash @orgdlist} is defined by
+%                           \texttt{\ttbackslash let}. Definition of
+%                           \texttt{\ttbackslash item[]} out of \LaTeX\
+%                           Version~2.09 $\langle$25 March 1992$\rangle$
+%                           (Perske)
+% \item[V 2.2 (23.09.1992)] Included Documentation Driver File and German
+%                           Documentation File into this \texttt{.doc}-File.
+%                           With Version 2.0 of \texttt{docstrip.tex} and the
+%                           Batchfile \texttt{install.rum} you can extract
+%                           them out of this \texttt{.doc}-File. (Perske)
+% \item[V 2.3 (26.05.1999)] The Definition of \texttt{\ttbackslash item[]} is
+%                           out of LaTeX2e $\langle$1997/12/01$\rangle$.
+%                           The distribution is now supplied under the
+%                           terms of the LPPL. The files were renamed
+%                           to \texttt{expdlist.dtx}, \texttt{expdlist.ins}
+%                           and \texttt{readme.txt}
+%                           (Kaspar)
+% \item[V 2.4 (22.09.1999)] Bugfix: percent added after
+%                           \texttt{\ttbackslash gdef\ttbackslash
+%                           set@break\ttlbrace\ttrbrace}.
