+With this option, for each new source file
+(call it \fIsrc/S\fP), rsync looks for a file \fIdest/D\fP anywhere in the
+destination that passes the quick check with \fIsrc/S\fP.  If such a \fIdest/D\fP
+is found, rsync uses it as an alternate basis for transferring \fIS\fP.  The
+idea is that if \fIsrc/S\fP was renamed from \fIsrc/D\fP (as opposed to \fIsrc/S\fP
+passing the quick check with \fIdest/D\fP by coincidence), the delta\-transfer
+algorithm will find that all the data matches between \fIsrc/S\fP and \fIdest/D\fP,
+and the transfer will be really fast.
