+\subsubsection{TmunuBase}
+The thorn \codename{TmunuBase} provides grid functions for the stress-energy
+tensor $T_{\mu\nu}$ as well as schedule groups to manage when $T_{\mu\nu}$ is
+calculated.  In a simulation many different thorns may contribute to the
+stress-energy tensor and this thorn allows them to do so without explicit
+dependence on each other.  The resulting stress-energy tensor can then be used
+by the spacetime evolution thorn (again without explicit dependence on any
+matter thorns).  When thorn \codename{MoL} is used for time evolution this
+provides a high order spacetime-matter coupling.
+
+The grid functions provided by \codename{TmunuBase} are:
+\begin{itemize}
+ \item The time component $T_{00}$: {\tt eTtt}
+ \item The mixed components $T_{0i}$: {\tt eTtx}, {\tt eTty}, {\tt eTtz}
+ \item The spatial components $T_{ij}$: {\tt eTxx}, {\tt eTxy}, {\tt eTxz}, {\tt eTyy}, {\tt eTyz}, {\tt eTzz}
+\end{itemize}
+In addition the grid scalar {\tt stress\_energy\_state} has the value 1 if storage is on for the stress-energy tensor and 0 if not.
+
+Thorn \codename{ADMCoupling} provides a similar (but older) interface between
+space-time and matter thorns. However, since it is based on an include file
+mechansim it is more complicated to use and we recommend all new matter thorns
+to use \codename{TmunuBase} instead.
