ALLOWED to take money for the distribution or use of this file (or a

You are allowed to distribute this file under the condition that it is
distributed together with all files mentioned in readme.mz2.
If you receive only some of these files from someone, complain!
However, if these files are distributed by established suppliers as
part of a complete TeX distribution, and the structure of the
distribution would make it difficult to distribute the whole set of
files, *those parties* are allowed to distribute only some of the
files provided that it is made clear that the user will get a complete
distribution-set upon request to that supplier (not me). Notice that
this permission is not granted to the end user.

% 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}
% \end{macro}
