+dit(bf(--inplace)) This causes rsync not to create a new copy of the file
+and then move it into place.  Instead rsync will overwrite the existing
+file, meaning that the rsync algorithm can't extract the full ammount of
+network reduction it might otherwise.
+
+This option is useful for transfer of large files with block based changes
+and also on systems that are disk bound not network bound.

+WARNING: If the transfer is interrupted, you will have an inconsistent file
+and the transfer should be run again.
