	\paragraph{Syntax}
 
 \begin{verbatim}
 EQUATION !! STEADY_STATE_EQUATION;
 \end{verbatim}
 \paragraph{Description}
 
 For each transition or measurement equation, you can provide a separate
 steady-state version. The steady-state version is used when you run the
 \href{model/sstate}{\texttt{sstate}} function. This is useful when you
 can substantially simplify some parts of the dynamic equations, and help
 therefore the numerical solver to achieve faster and more accurate
 results.
 
 Why is it the double exclamation point, \texttt{!!}, that is used to
 start the steady-state versions of equations? Because if you associate
 your model file extension with the Matlab editor, anything after an
 exclamation point is displayed red making it easier to spot the
 steady-state equations.
 
 \paragraph{Example 1}
 
 \begin{verbatim}
 Lambda = Lambda{1}*(1+r)*beta !! r = 1/beta - 1;
 \end{verbatim}
 \paragraph{Example 2}
 
 \begin{verbatim}
 log(A) = log(A{-1}) + epsilon_a !! A = 1;
 \end{verbatim}
