      Simple Authentication and Security Layer framework Library.

      GNU SASL is an implementation of the Simple Authentication and

      Security Layer framework and a few common SASL mechanisms.

      SASL is used by network servers (e.g., IMAP, SMTP) to request

      authentication from clients, and in clients to authenticate

      against servers.
