  We describe an algorithm computing the monodromy and the pole order
filtration on the Milnor fiber cohomology of any reduced projective plane curve
$C$. The relation to the zero set of Bernstein-Sato polynomial of the defining
homogeneous polynomial for $C$ is also discussed. When $C$ has some non
weighted homogeneous singularities, then we have to assume that a conjecture
holds in order to get some of our results. In all the examples computed so far
this conjecture holds.
