Thanks. 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.
