  We present a library autgradalg.lib for the free computer algebra system
Singular to compute automorphisms of integral, finitely generated
$\mathbb{C}$-algebras that are graded pointedly by a finitely generated abelian
group. It implements the algorithms developed in 'Computing automorphisms of
Mori dream spaces'. We apply the algorithms to Mori dream spaces and
investigate the automorphism groups of a series of Fano varieties.
