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