 \section{Overview}
 
-The Carpet driver, which lives in the Carpet arrangement, is divided
-into several parts.  The thorn \texttt{Carpet} is the main driver
-piece; it provides all the routines and structures that Cactus expects
-from it.  The thorn \texttt{CarpetLib} is the workhorse that does all
-the bookkeeping and data shuffling.  Those two alone form a valid
-Cactus driver; the other thorns provide additional functionality.  The
-thorns \texttt{CarpetInterp}, \texttt{CarpetReduce}, and
-\texttt{CarpetSlab} provide the corresponding interpolation,
-reduction, and slabbing interfaces.  The thorns \texttt{CarpetIOASCII}
-and \texttt{CarpetIOFlexIO} provide I/O methods.  Finally, thorn
-\texttt{CarpetRegrid} provides a user interface to select where and
-what to refine.  (The actual refinement is handled in
-\texttt{CarpetLib}.)
