I know about pkg query (and in fact my script uses something very much like that to get the initial list of automatic packages). What I was trying to do was get a list of packages installed but not in another list. The other list represents _future_ automatic packages but not necessarily what is in the database now. In any case, I worked around it but first unsetting all packages and then setting the user-selected list back to automatic.
