s3sync miss ACLs for "directory"(node) ?

[cxnhbf]

Hi there,

/etc/s3sync/s3sync.rb --verbose --ssl   ./xxx.xxx bucket:backup/full/test

the file xxx.xxx on S3 has the right ACL. But the folder, such as backup, full, test doesn't come with ACL.

As I know, s3sync.rb doesn't have [header] option for us to set ACL.

Thanks
