(description
"Eigen is a C++ template library for linear algebra: matrices, vectors,
numerical solvers, and related algorithms. It provides an elegant API based
on \"expression templates\". It is versatile: it supports all matrix sizes,
all standard numeric types, various matrix decompositions and geometry
features, and more.")
