#-------------------------------------------------------------------------
# The following block of tests - filefmt-2.* - test that versions 3.7.0
# and later can read and write databases that have been modified or created
# by 3.6.23.1 and earlier. The difference difference is that 3.7.0 stores
# the size of the database in the database file header, whereas 3.6.23.1
# always derives this from the size of the file.
