# embl2gff writes out a gff file that does not have the md5 sum in it.
# I do not want to cut/paste bob's code for computing md5 to avoid drift
# but that code requires the full gff file to be ready to run.  By the
# time we have the full gff file, it's often a GB long.  Pulling up vi
# to change 10 bytes in the first 200 bytes of a GB files is a tedious
# waste of time; hence, this little helper utility.
