%global _description %{expand:
Basix is a finite element definition and tabulation runtime library, and one of
the core components of FEniCSx. It supports a range of finite elements on
simplex and tensor-product cells, arbitrary-order Lagrange and vector elements,
and provides quadrature rules and cell geometry information.}
