A quasi-Poisson manifold is a $G$-manifold equipped with an invariant
bivector field whose Schouten bracket is the trivector field generated
by the invariant element in $\wedge^3 \g$ associated to an invariant
inner product. We introduce the concept of the fusion of such
manifolds, and we relate the quasi-Poisson manifolds to the previously
introduced quasi-Hamiltonian manifolds with group-valued moment maps.
