  We prove the existence of a minimal (all leaves dense) foliation of
codimension one, on every closed manifold of dimension at least 4 whose Euler
characteristic is null, in every homotopy class of hyperplanes distributions,
in every homotopy class of Haefliger structures, in every differentiability
class, under the obvious embedding assumption. The proof uses only elementary
means, and reproves Thurston's existence theorem in all dimensions. A
parametric version is also established.
