+     "The @code{SparseArray} package is an infrastructure package that
+provides an array-like container for efficient in-memory representation of
+multidimensional sparse data in R.  The package defines the @code{SparseArray}
+virtual class and two concrete subclasses: @code{COO_SparseArray} and
+@code{SVT_SparseArray}.  Each subclass uses its own internal representation of
+the nonzero multidimensional data, the \"COO layout\" and the \"SVT layout\",
+respectively.  @code{SVT_SparseArray} objects mimic as much as possible the
+behavior of ordinary matrix and array objects in base R.  In particular, they
+suppport most of the \"standard matrix and array API\" defined in base R and
+in the @code{matrixStats} package from CRAN.")
