% Set up styles to match behaviour of \pkg{ifsym}. Slope and size is is adjusted.
% The macros only have 60\% of the height.

%    \end{macrocode}
% Define "|" to create a glitch. While it can be ignored in "H|L" or "L|H" it can
% also be used like "L|L" and "H|H".
%    \begin{macrocode}
    timing/metachar={|}{G},
%    \end{macrocode}
% The "X" is used for "M" and is set to black. 
%    \begin{macrocode}
    timing/x/.style={},
%    \end{macrocode}
% Define "M"/"m" to be equal to "X"/"x":

% The |setdslope| macro is redefined to allow value higher than 1.

% The "<" and ">" characters are defined as code characters. They
% check if there appear twice which doubles their width.
% A macro is used to remove the second appearance from the input.
