% \subsection{The \texttt{wargame.natoapp6c} \TikZ{} library}
%
% In this section we define the code for the Tikz library. The
% library defines a number of \spec{pic} keys we can use to draw
% various parts of a marker.  The markers conform to NATO App~6(c)
% specification.  The implementation here is heavily inspired by the
% package \textsf{milsymb} \cite{milsymb} available at CTAN.

% \subsubsection{Some dimensions}
%
% We define a number of dimensions which we will use in the
% following.  They provide a rough parameterisation of the node
% shapes, but shouldn't really be changed.  We have them here so that
% the code uses as few hard coded numbers as possible.
%
% The dimensions are
% \begin{itemize}
% \item Installation `hat' $x$ coordinate
% \item Installation `hat' height
% \item Activity width of boxes
% \item Height of space bar
% \item Radius of the symbol 
% \end{itemize}
% 
%    \begin{macrocode}
\newdimen\n@to@pp@inst@x\n@to@pp@inst@x=0.2cm
