-This patch provides --flags, which preserves the st_flags field.
+This patch provides --fileflags, which preserves the st_flags stat() field.
Modified from a patch that was written by Rolf Grossmann.
To use this patch, run these commands for a successful build:
./configure
make
-TODO: fix --delete-delay to work with --flags option.
