13: from one user to another.
14: The latter case is the one summarized above and
15: described here.
16: See login_____ (VII) for how to dial up initially.

18: If login_____ is invoked without an argument,
19: it will ask for a user name, and, if
20: appropriate, a password.
21: Echoing is turned off (if possible) during the typing of the password,
22: so it will not appear on the written record of the
23: session.
