+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: The file's data will be in an inconsistent state during the
+transfer (and possibly afterwards if the transfer gets interrupted), so you
+should not use this option to update files that are in use. Also note that
+rsync will not update a file inplace that is not writable by the receiving
+user.
