+  \summary{}
+
+  \begin{itemize}
+  \item General cleanup of C++ code
+  \item Pyrex/pyrexembed replaced by SWIG
+    \begin{itemize}
+    \item Greatly simplifies creating Python bindings for C++ objects
+    \item SWIG generated files included in source distribution
+    \item User-defined spatial databases and bulk constitutive models
+    \end{itemize}
+  \item Automatic nondimensionalization of problem
+    \begin{itemize}
+    \item User supplies pressure, time, and length scale of problem
+    \item All parameters nondimensionalized appropriately
+    \item Eliminates need to condition terms in sparse matrix
+    \item Restores symmetry of sparse matrix (reduces memory use)
+    \end{itemize}
+  \item Integration with PETSc Scalable Nonlinear Equations Solvers
+   \begin{itemize}
+    \item Displacement increment formulation for implicit and dynamic 
+      time-stepping
+   \end{itemize}
