SYNOPSIS
        #include 

        int handle_external_signal(int signal)

DESCRIPTION
        If the driver receives a signal from the OS it forwards it to the
        mudlib master by calling this function. The signal received by the
        driver is given in  and may be one of the following:
        SIGHUP, SIGINT, SIGTERM, SIGUSR1, SIGUSR2.

        If this function returns != 0, the driver will assume the signal has
        been dealt with and take NO further action.
        The exception is SIGTERM, which can't be handled. The driver will
        perform a graceful shutdown of the game after this function returns.

        If the master does not handle the signal (returns 0 or this function
        doe not exit), the driver will perform the following default actions:

        SIGHUP:  begin a graceful shutdown
        SIGINT:  send itself an unhandled SIGINT. This usually causes an
                 immediate and non-graceful shutdown.
        SIGUSR1: the driver will reload the master object
        SIGUSR2: the driver will re-open its debug log file
                 (this will happen the next time the driver writes to it)
