R help - Dec 2008 - making sense of posterior statistics in the deal package

Hello,
    I'm doing bayesian network analyses with the deal package.  I am at a
loss for how to interpret output from the analysis (i.e. what is a good score,
what is a bad score, which stats tell me what about the network edges/nodes).

Here is an example node with its posterior scores for all parent nodes.
