  We study contact structures on nonnegatively-graded manifolds equipped with
homological contact vector fields. In the degree 1 case, we show that there is
a one-to-one correspondence between such structures (with fixed contact form)
and Jacobi manifolds. This correspondence allows us to reinterpret the
Poissonization procedure, taking Jacobi manifolds to Poisson manifolds, as a
supergeometric version of symplectization.
