+The singular value decomposition (SVD) is an important factorization
+of a rectangular real matrix
+- see http://en.wikipedia.org/wiki/Singular_value_decomposition.
+
+Eigendecomposition is the factorization of a matrix into a canonical
+form, whereby the matrix is represented in terms of its eigenvalues
+and eigenvectors
+- see http://en.wikipedia.org/wiki/Eigendecomposition_of_a_matrix.
+
+This module implements the SVD and Eigen decomposition routines of
+the The C GNU Scientific Library (GSL).
+
+It provides simple convenience methods in the upper-level
+Math::GSL::Linalg::SVD namespace to perform these operations.
+Alternatively, it also provides direct access to the C routines in
+the Math::GSL::Linalg::SVD::Matrix, Math::GSL::Linalg::SVD::Vector
+and Math::GSL::Linalg::SVD::Eigen namespaces - see METHODS.

+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
