	They are.  The first entry says to check doc/misc/options.

	Depends how you define the functionality.  If you define
	it as fetching deltas in a platform independent way, the
	functionality is there.

	If you define it as being able to replace the standard zone
	transfer mechanisms and have them automatically triggered
	then it is not there.

	Note with rsync driven from the slave end you may pick up
	a incomplete zone.  This is less likely to happen if the
	process is driven from the master.
