% This style option is stored in the file \verb+thb.sty+.

%    \begin{macrocode}
\begingroup \makeatletter
\@ifundefined{theorem@style}{\input{theorem.sty}}{}
%    \end{macrocode}
% First, we
% show the version\footnote{This file has version number
% \fileversion, last revised \filedate, documentation dated \docdate.}
% of this file:
%    \begin{macrocode}
\typeout{Style-Option: `theorem-break' \fileversion \space\space
         <\filedate>  (FMi)}
\typeout{English Dokumentation \@spaces\@spaces\@spaces\space\space
         \space <\docdate>  (FMi)}
%    \end{macrocode}
%
% \begin{macro}{\th@break}
%    \verb+\theoremstyle{break}+ produces a line break after the name
%    of the theorem.  The font is \verb+\sl+.  Hence, we define
%    \verb+\th@break+ as follows:
%    \begin{macrocode}
\gdef\th@break{\sl
  \def\@begintheorem##1##2{\item[%
%    \end{macrocode}
%    We run into the following problem: it is not possible to create
%    the header with \verb+\item[+\meta{title}\verb+]+ and then start
%    a new line by, for example, \verb+\mbox{}\\+. Such a definition
%    will fail whenever a list environment follows immediately.  With
%    the above construction, the \verb+\mbox{}+ causes the switch
%    \verb+@inlabel+ (cf.\ definition of \verb+\list+ and
%    \verb+\trivlist+ in \cite{latex:source}) to be set to {\tt false}
%    and so the following list will insert additional vertical
%    space (\verb+\topskip+). This is quite annoying. Therefore, we
%    create the line break within the \verb+\item+. In order to ensure
%    that the text will begin at the proper position in the following
%    line, we simply pretend that the label does not take any
%    room.\footnote{This will lead to problems whenever very high
%    symbols occurring in the line tower into the
%    heading. So, something else has to be done here sometime.}
%    \begin{macrocode}
       \rlap{\vbox{\hbox{\hskip \labelsep\theorem@headerfont ##1\ ##2}%
                   \hbox{\strut}}}]}%
%    \end{macrocode}
%    Again, the definition of \verb+\@opargbegintheorem+ is
%    completely analogous.
%    \begin{macrocode}
\def\@opargbegintheorem##1##2##3{%
  \item[\rlap{\vbox{\hbox{\hskip \labelsep \theorem@headerfont
                     ##1\ ##2\ (##3)}%
                    \hbox{\strut}}}]}}
\endgroup
%    \end{macrocode}
