Query: A finitely presented subgroup of the automorphism group of a
  right-angled Artin group   Let G be a right-angled Artin group. We use geometric methods to compute a
presentation of the subgroup H of Aut(G) consisting of the automorphisms that
send each generator to a conjugate of itself. This generalizes a result of
McCool on basis-conjugating automorphisms of free groups.
