  21 # Description:
  22 # Restoring of directory modes and timestamps works correctly only
  23 # if the archive has normal member ordering, i.e. each directory
  24 # member is immediately followed by members located under that directory.
  25 # This is not true for incremental archives, where directory members
  26 # precede the non-directory ones. Due to this, GNU tar up to version 1.15.2
  27 # failed to correctly restore directory timestamps from an incremental
  28 # archive if this directory contained some files in it.
