+-cut_out is not yet coordinated with -compare_r and -update_r.
+But the names of the part files in this example already follow a
+future convention by which xorriso will be able to recognize
+file parts and process them accordingly:
+.br
+A disk file gets mapped to a ISO directory. Its split parts
+have names which describe the splitting by 5 numbers which are separated
+by some text:
+.br
+part_number, total_parts, byte_offset, byte_count, disk_path_size
+.br
+Scaling characters like "m" or "k" are taken into respect and may
+serve as separators as well. All digits are interpreted as decimal,
+even if leading zeros are present.
+.br
+Not all parts have to be present on the same media. But those parts
+which are present have to sit in the same directory. No other files
+are allowed in there. Parts have to be disjoint. Their numbers have
+to be plausible. byte_count must be valid as -cut_out argument.
