The system command names the remote system. You must specify
the correct name of the remote system, not an alias you invented,
because uucico will check it against what the remote system says
it is called when you log on.
Each system name may appear more only once. If you want to use several sets of configurations for the same system (such as different telephone numbers uucico should try in turn), you can specify alternates. Alternates are described below.
