# TEST env003
# TEST Test DB_TMP_DIR and env name resolution
# TEST With an environment path specified using -home, and then again
# TEST with it specified by the environment variable DB_HOME:
# TEST 1) Make sure that the DB_TMP_DIR config file option is respected
# TEST a) as a relative pathname.
# TEST b) as an absolute pathname.
# TEST 2) Make sure that the -tmp_dir config option is respected,
# TEST again as relative and absolute pathnames.
# TEST 3) Make sure that if -both- -tmp_dir and a file are present,
# TEST only the file is respected (see doc/env/naming.html).
