+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.

 is not used and the whole file is sent as-is instead.  The transfer may be
 faster if this option is used when the bandwidth between the source and
