By default, dirpacker displays a list of bins and the files they
would contain, along with the size of each file and some statistics.
With the option --machine-readable, this list will be printed in a
machine-readable format: each line contains a bin's name, then a
tabulation, then a file that belongs to this bin.
With the option --move, a directory will be created for each volume and
the files will be moved to the corresponding volume.
