R help - Mar 2012 - Obtain Log-Likelihood for ml.nbc (COUNT)

Dear List,

I normally try to solve this kind of problems by myself but I am running out of
time and have
no idea where to start. So I hope you might excuse this rather basic question.

I'm trying to fit a Canonical Negative Binomial model using the ml.nbc
function from the
COUNT package. This function only outputs a "normal" regression table
with the parameter
estimators and so on. But for further testing I need the log-likelihood. And I
have no idea how
to easily obtain it. I think this question extends to all ml-estimators which
are "non-standard-
functions". 

Any pointers for me how I can progress?

All the best.
