+     "This package implements sparse arrays of arbitrary dimension on top of
+@code{numpy} and @code{scipy.sparse}.  Sparse array is a matrix in which most
+of the elements are zero.  @code{python-sparse} generalizes the
+@code{scipy.sparse.coo_matrix} and @code{scipy.sparse.dok_matrix} layouts, but
+extends beyond just rows and columns to an arbitrary number of dimensions.
+Additionally, this project maintains compatibility with the
+@code{numpy.ndarray} interface rather than the @code{numpy.matrix} interface
+used in @code{scipy.sparse}.  These differences make this project useful in
+certain situations where @code{scipy.sparse} matrices are not well suited, but
+it should not be considered a full replacement.  It lacks layouts that are not
+easily generalized like @dfn{compressed sparse row/column}(CSR/CSC) and
+depends on @code{scipy.sparse} for some computations.")
