    NAME
        Dout - Print debug output

    SYNOPSIS
        void Dout(char *subname, int level, char *msg, ...)

    DESCRIPTION
        Dout prints debugging output if debugging is turned
        on (-x specified) and the level of this message is
        lower than the value of the global variable debug.
        The subroutine name is printed if it is not a null
        string.
