+   The acausal bond graph of system \textbf{TwoPorts} is
+   displayed in Figure \Ref{fig:TwoPorts_abg.ps}; it contains the two
+   port components: \textbf{TF} and \textbf{GY} in each of
+   the two possible causalities.
+   
+   Note that the neither component has prefered causality and, in both
+   cases, a causal stroke must be provided by the user. 
+   
+   Section \Ref{sec:TwoPorts_ode.tex} gives the system equations.
