  Beginning with a skew-symmetric matrix, we define a certain Poisson--Lie
group. Its Poisson bracket can be viewed as a cocycle perturbation of the
linear (or "Lie-Poisson") Poisson bracket. By analyzing this Poisson structure,
we gather enough information to construct a C*-algebraic locally compact
quantum group, via the "cocycle bicrossed product construction" method. The
quantum group thus obtained is shown to be a deformation quantization of the
Poisson-Lie group, in the sense of Rieffel.
