        strings .DIR | grep "^M\.[0-9]" | grep "[0-9]\.A$" | sort >
_TMP_FILE_DOT_DIR_
        diff _TMP_FILE_IN_DIR_ _TMP_FILE_DOT_DIR_ | grep "^< " | sed 's/^<
//' > _FILE_DIFF_
        for file in `cat _FILE_DIFF_`
        do
                # echo "rm $file"
                rm $file
        done
        rm -f _TMP_FILE_IN_DIR_ _TMP_FILE_DOT_DIR_ _FILE_DIFF_
        cd ..
