This option requests that rstart be verbose in its operation. Without this option, rstart discards output from the remote's rstart helper, and directs the rstart helper to detach the program from the rsh connection used to start it. With this option, responses from the helper are displayed and the resulting program is not detached from the connection. This is a trivial implementation. Far more sophisticated implementations are possible and should be developed.
Error handling is nonexistant.
Without -v, error reports from the remote are discarded silently. With -v, error reports are displayed. If it starts with a colon, the local hostname is prepended. The local domain name should be appended to unqualified host names, but isn't. X11 authority information is passed for the current display.
