remote copies of rsync. Typically, rsync is configured to use rsh by
default, but you may prefer to use ssh because of its high security.
+Feel free to include options in the COMMAND. For instance:
+
+quote(-e "ssh -1 -l joe")
+
+(Note that ssh users can alternately customize site-specific connect
+options in their .ssh/config file.)

You can also choose the remote shell program using the RSYNC_RSH
environment variable.
