+\section{Introduction}
+
+
+The \ahf{} thorn locates apparent horizons using the direct method
+described in \cite{Thornburg-1996-horizon-finding}, modified to work
+with Cartesian $(x,y,z)$-grid input data, and using the multiple-patch
+scheme described in \cite{Thornburg-2000-mpe-mg9}.
+
+In this method we posing the apparent horizon equation as an elliptic
+PDE on angular-coordinate space, and solve this PDE using a global
+Newton (actually Newton-Kantorovich) method, updating all points
+simultaneously at each iteration.  We use a sparse $\sf LU$ decomposition
+for the underlying linear-equation solver.
