  We show that the quasi-stationary states observed in the $N$-particle
dynamics of the Hamiltonian Mean-Field (HMF) model are nothing but Vlasov
stable homogeneous (zero magnetization) states. There is an infinity of Vlasov
stable homogeneous states corresponding to different initial momentum
distributions. Tsallis $q$-exponentials in momentum, homogeneous in angle,
distribution functions are possible, however, they are not special in any
respect, among an infinity of others. All Vlasov stable homogeneous states lose
their stability because of finite $N$ effects and, after a relaxation time
diverging with a power-law of the number of particles, the system converges to
the Boltzmann-Gibbs equilibrium.
