Maybe I misunderstand you.. I was talking about this test, which was
in Greg's script already:

if [ ! -d ${ARCHIVE} ] ; then
  echo Archive directory does not exist >&2
  exit 1
fi

I don't see how it would make any difference performance-wise whether
this block is moved up to right before the "if [ -f ${ARCHIVE}/${FILE}
] ; then" line: we expect both of these if-statements to evaluate
false if they are reached.
