# quoted list of quoted strings) against it with ovsdb-client one at a
# time.

# Checks that the overall output is OUTPUT, but UUIDs in the output
# are replaced by markers of the form <N> where N is a number.  The

# If a given UUID appears more than once it is always replaced by the

#
# Additionally, checks that records written to a database file can be
