          open:       fn(user, password, server: string): (int, string);
          stat:       fn(): (int, string, int, int);
          msglist:    fn(): (int, string, list of (int, int));
          msgnolist:  fn(): (int, string, list of int);

     DESCRIPTION
          Pop3 provides an interface to the Post Office Protocol POP3
          through a set of functions.

          Open opens a connection to a POP3 server, logging in as the
          specified user with the given password. If server is nil,
          open uses $MAILSERVER, the default mail server, if set up in
          `/services/cs/db' (see db(6)). The remaining functions
          assume a successfully opened connection.

          Stat returns the status of the user's mailbox.  The third
          element of its return tuple is the number of messages and
          the fourth is the total number of bytes in the messages.

          Msglist lists the user's mailbox. The third element in its
          return tuple gives a list of pairs of numbers comprising
          (message number, bytes in message).

          Msgnolist lists the user's mailbox as above but omits the
          bytes in each message.

          Top returns the top of message m.

          Get returns the full text of message m.

          Delete deletes message m.

          Close closes the connection to the POP3 server.  Note that
          subsequent reconnections to the server may renumber the mes-
          sages in the mail box and will certainly do so if the last
          connection deleted messages.

          Note also that a connection is static in the sense that mail
          messages entering the server during a connection will not be

          accessible. A reconnection is needed to see newly arrived
          messages.
