+Unfortunately more advanced radiative and/or constraint preserving boundary
+conditions are not available in the Einstein Toolkit at the present time.
+However, {\tt Cactus} is a flexible and extensible framework and supports data
+structures (such as lower dimensional grid arrays) that could be used for
+implementing more advanced outer boundary conditions.  It will be the
+requirements and needs of the numerical relativity community that decides
+which enhancements and improvements will be added to the toolkit.
