Thanks David.  I agree that README in the service home directory is a 
good idea.  It seems though that it would be good to have something 
easily accessible if the server were not running at all.  I don't know, 
I tend to violate the 'the perfect is the enemy of the good' dictum 
rather often.

Anyway, I'm glad you are on the case at this point, I don't have 
anything further to contribute.  I don't think it is an issue that can't 
wait hours or even a day or more to be resolved, work on it when your 
life allows.
