# check md5 refs
#
# This script will be used to make sure we never introduce a regression on any
# of the nonregression file.
#
# The approach is relatively simple, we compute a md5sum for each of the decode
# file. Anytime the md5sum is different from the reference one, we assume
# something went wrong and simply fails. of course if could happen during the
# course of openjpeg development that the internals are changed that impact the
# decoding process that the output would be bitwise different (while PSNR would
# be kept identical).
