# Test script for the h4toh5 tests.
# Using the h4toh5 convert to convert a pre-created hdf file to
# an hdf5 file (output file), then compare it with a pre-created
# corresponding hdf5 file (expected file).
# If the same, that particular test passes.
# If not the same, the output file and expected file are processed
# by the h5dump tool to see if they produce the same results.
# If the same, the test passes.
# If not, show the difference of the two results and report the test failed.
#
# h5dump is default to use the one just built.  It can be overridden
# by setting $H5DUMP to a different value such as /usr/local/bin/h5dump.
