+#                <program> <args...>
+#
+#   where:
+#     <hostname>    is the remote host to execute the program,
+#     <login_name>  is the username on the remote host,
+#     <port>        is the port used by the remote client,
+#     <program>     is the path to the program to run,
+#     <args...>     are the arguments to pass to the program.
