-\subsubsection{Variable Modifiers}
-
-Rule variable names can be modified in several ways. You can define
-meta-variables using the \$ operator. These can be used with the variable
-modifier operators {\tt ?}  and {\tt -}, as described in the following table: 
-
-\begin{center}
-\begin{tabular}{| l | p{4.5in} |}
-
-\hline
-\textbf{Variable Syntax} & \textbf{Description}\\
-\hline
-
-\hline
-\texttt{var} &
-
-Defines a meta-variable.\\
-
-\hline
-\texttt{\$(var) or \$var} &
-
-Replaces with the contents of variable \texttt{var}.\\
-
-\hline
-\texttt{\$(var:-default)} &
-
-Replaces the contents of the variable \texttt{var} with ``default'' if
-\texttt{var} is undefined.\\
-
-\hline
-\texttt{\$(var:?message)} &
-
-Replaces with the contents of variable \texttt{var} or prints out the error
-message and exits.\\
-
-\hline
-\end{tabular}
-\end{center}
-
-Here is an example of advanced variable usage in action:
-
-\begin{verbatim}
-    ipvar MY_NET 192.168.1.0/24
-    log tcp any any -> $(MY_NET:?MY_NET is undefined!) 23
-\end{verbatim}
