    "dread -l" will do the trick (next time, you might want to read the
    man pages first before posting a question to the net at large).

actually, dread *won't* do the trick -- it only tells you what defaults
are already set.  if you want to find them all, try this:

    start the program you're interested in under gdb
    (e.g. 'gdb /NextApps/Librarian.app/Librarian')

    give gdb the following string of commands:

	break  *0x605d89e
	commands 1
	silent
	printf "%s: ", *$a2
	output {char *}(4+$a2)
	echo \n
	cont
	end
	run

    this should give you something like the following:
    (the values given are the application defaults, i.e. what you'll
     get if there's nothing in your defaults database)

(note that most of the preferences are loaded by appkit, and have
nothing to do with librarian specifically.)

this also starts the program running; you'll probably want to quit it,
and then quit gdb (by typing 'quit').

by the way, the magic number in the first line is an address in the shared
library (NXRegisterDefaults+70), and almost certainly will have to be
changed to work under 2.0.

have fun...
