  We perform two explicit computations of bordered Heegaard Floer invariants.
The first is the type D trimodule associated to the trivial S^1 bundle over the
pair of pants P. The second is a bimodule that is necessary for self-gluing,
when two torus boundary components of a bordered manifold are glued to each
other. Using the results of these two computations, we describe an algorithm
for computing HF-hat of any graph manifold.
