% This section contains the final settings for \LaTeX.  It initilizes
% some debugging and typesetting parameters, sets the default
% |\catcode|s, and inputs the hyphenation file.

% \subsection{Debugging}
%
% \begin{macro}{\showoverfull}
% \changes{v0.1k}{1994/05/19}{used \cs{@ne} not 1}
% \begin{macro}{\showoutput}
% The following commands are used in debugging:
% \changes{v0.1k}{1994/05/19}{used \cs{maxdimen} not 99999}
%    \begin{macrocode}
%<*2ekernel>

\def\showoutput{\tracingonline\@ne\tracingoutput\@ne
    \showboxbreadth\maxdimen\showboxdepth\maxdimen\errorstopmode}

% \end{macro}

% By default, \LaTeX{} shows statistics:
%    \begin{macrocode}
\tracingstats1
%    \end{macrocode}
% \changes{v0.1g}{1994/05/05}{Set error help empty.}
% Empty the error help message, which may have some rubbish:
%    \begin{macrocode}
\errhelp{}
%    \end{macrocode}
% 
%
% \subsection{Typesetting parameters}
%
% \begin{macro}{\@lowpenalty}
% \begin{macro}{\@medpenalty}
% \begin{macro}{\@highpenalty}
%    These are penalties used internally.
%    \begin{macrocode}
\newcount\@lowpenalty
\newcount\@medpenalty
\newcount\@highpenalty
%    \end{macrocode}
% \end{macro}
% \end{macro}
% \end{macro}
% The default values of the picture and |\fbox| parameters:
%    \begin{macrocode}
\unitlength = 1pt
\fboxsep = 3pt
\fboxrule = .4pt
%    \end{macrocode}
% The saved value of \TeX's |\maxdepth|:
%    \begin{macrocode}
\@maxdepth       = \maxdepth
%    \end{macrocode}
% |\vsize| initialized because a |\clearpage| with |\vsize < \topskip|
%  causes trouble.
% |\@colroom| and |\@colht| also initialized because |\vsize| may be
%  set to them if a |\clearpage| is done before the |\begin{document}|
%
%    \begin{macrocode}
\vsize = 1000pt
\@colroom = \vsize
\@colht = \vsize
%    \end{macrocode}
% Initialise |\textheight| |\textwidth| and page style, to avoid
% internal errors if they are not set by the class.
% \changes{v0.1b}{1994/04/18}
%         {Initialise \cmd\textheight\ \cmd\textwidth\ and page style}

%         {use \cmd\InputIfFileExists not \cmd\IfFileExists}
%
% The following code will be compiled into the format file. It checks
% for the existance of \texttt{lthyphen.cfg} in inputs that file if
% found. Otherwise it inputs \texttt{lthyphen.ltx}.  Note that these
% are loaded in \emph{before} the |\catcode|s are set, so local
% hyphenation files can use 8-bit input.
%
% We try to load the customized hyphenation description file.
%    \begin{macrocode}

%
%
% \subsection{Font loading}
%    Fonts loaded during the formatting process might already have
%    changed the |\font@submax| from |0pt| to something higher.
%    If so be put out a bold warning.
% \changes{v0.1l}{1994/05/20}{Use new font warning commands}
