Rserv question or docs?

Hi is there any documentation for rserv other than the readme?

I've got it working and I'm generally understanding what's going
on by reading the code and observing the changes to the
various _rserv_ tables but I would feel much more comfortable if
I could read or someone could explain exactly what is supposed to get
logged by the trigger and exactly how the Replicate script is supposed to
copy the data using the _rserv_log_ to the secondary server.

Thanks,

Alex.
