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.
