# TEST	env007
# TEST	Test DB_CONFIG config file options for berkdb env.
# TEST	1) Make sure command line option is respected
# TEST	2) Make sure that config file option is respected
# TEST	3) Make sure that if -both- DB_CONFIG and the set_<whatever>
# TEST		method is used, only the file is respected.
# TEST	Then test all known config options.
# TEST	Also test config options on berkdb open.  This isn't
# TEST	really env testing, but there's no better place to put it.
