% I will not use real math. But there will be some »pseudo math code«. So I
% need some macros for this.
%
% \begin{macro}{\Var}
%   Variables (in real math simply |$a$| will be |\Var{a}| in my math:
%    \begin{macrocode}

%    \end{macrocode}
% \end{macro}
%
% \begin{macro}{\Unit}
%   The unit of a length.
%    \begin{macrocode}
\newcommand*{\Unit}[1]{\,\ifmmode \textrm{#1}\else #1\fi}
%    \end{macrocode}

% \section{Special Tabulars and Tables}
%
% I need some special tabulars and tables. These are used for describing
% single topics.
%
% \begin{environment}{desctabular}
%   This kind of tabluar has primary one column but uses two columns in
%   declaration. It's something like a \texttt{description} environment with
%   line break after the item. I've used a \texttt{tabular} at the definition
%   because of full compatibitlity with \texttt{desctable}.
% \begin{length}{\descwidth}
%   I need a length of local usage. I could have used |\@tempdima| or
%   another local length from kernel. But I've decided not to try to find a
%   unused length at \texttt{tabular} environment.
% \begin{length}{\descdefaultindent}
%   And I need a length of global usage.
%    \begin{macrocode}
\newlength{\descwidth}
\newlength{\descdefaultindent}\setlength{\descdefaultindent}{2em}
%    \end{macrocode}
% \end{length}

%   The definition of \texttt{desctabular} is very simple, because the main
%   work will be done by a \emph{worker} macro that will be defined later.

% Now we have to define different kinds of index entries. We have entries that
% will be added to only one index. We have entries that will be added to one
% index with reference to that index at another index. And there are even
% entries that will be added to one index with reference to to that index from
% another index and from the main index.
% \begin{macro}{\DefineSingeIndex}
%   This defines a single index entry, e.g. of commands. A macro will be
%   defined that addes the entry only to one index. First (optional)
%   agrument is a not, which shows the kind of entry (e.g. |\GuideMacro|). The
%   second is the macro postfix (e.g. \texttt{Cmd} would define |\IndexCmd|).
%   The third is the shortcut of the index to bee used
%   (e.g. \texttt{cmd}). The fourth argument is the command to be used to
%   output (format) the index entries (e.g. |\Macro|).

% \begin{macro}{\DefineDoubleIndex}
%   This defines a double index entry, e.g. of page styles. A macro will be
%   defined that adds the entry to an index and also adds a reference entry to
%   the main index. See |\DefineSingleIndex| for informations about the
%   parameters. If a note was given (first optional argument) it will be used
%   to make a top level entry to the main index with the corresponding
%   subentry.

% \begin{macro}{\DefineTripleIndex}
%   This defines a triple index entry, e.g. of lengths. A macro will be
%   defined that adds the entry to an index and also adds a reference entry to
%   another index and the main index. The first (optional) argument is a note
%   (e.g. (|\GuideLength|) that will be used to generate a top level index
%   entry to the main index. The second argument is the macro postfix
%   (e.g. \texttt{Length} to define |\IndexLength|). The third argument is the
%   shortcut of the primary index (e.g. \texttt{len}). The fourth argument is
%   the short name of that index (e.g. |\GuidelenIndexShort|). The fifth
%   argument is the shortcut of the index to put the reference into
%   (e.g. \texttt{cmd}). The sixth argument is the output command of the index
%   entry (e.g. |\Length|).
