This modification adds a new gettytab(5) option (iM) to specify a program to run that will generate the initial (banner) message that is displayed before the login prompt. Such a capability is useful when dynamic information is needed in the banner message that cannot be supplied by the set of % substitution sequences available in the "im" option.
