        !             5:  *
        !             6:  *     These are used as the first parameter to logmsg().
        !             7:  *     Their meanings are approximately as follows:
        !             8:  *
        !             9:  *     LOG_ALERT -- this priority should essentially never
        !            10:  *             be used.  It applies only to messages that
        !            11:  *             are so important that every user should be
        !            12:  *             aware of them, e.g., a serious hardware failure.
        !            13:  *     LOG_SALERT -- messages of this priority should be
        !            14:  *             issued only when immediate attention is needed
        !            15:  *             by a qualified system person, e.g., when some
        !            16:  *             valuable system resource dissappears.  They get
        !            17:  *             sent to a list of system people.
        !            18:  *     LOG_EMERG -- Emergency messages are not sent to users,
        !            19:  *             but represent major conditions.  An example
        !            20:  *             might be hard disk failures.  These could be
        !            21:  *             logged in a separate file so that critical
        !            22:  *             conditions could be easily scanned.
        !            23:  *     LOG_ERR -- these represent error conditions, such as soft
        !            24:  *             disk failures, etc.
        !            25:  *     LOG_CRIT -- such messages contain critical information,
        !            26:  *             but which can not be classed as errors, for example,
        !            27:  *             'su' attempts.
        !            28:  *     LOG_WARNING -- issued when an abnormal condition has been
        !            29:  *             detected, but recovery can take place.
        !            30:  *     LOG_NOTICE -- something that falls in the class of
        !            31:  *             "important information"; this class is informational
        !            32:  *             but important enough that you don't want to throw
        !            33:  *             it away casually.
        !            34:  *     LOG_INFO -- information level messages.  These messages
        !            35:  *             could be thrown away without problems, but should
        !            36:  *             be included if you want to keep a close watch on
        !            37:  *             your system.
        !            38:  *     LOG_DEBUG -- it may be useful to log certain debugging
        !            39:  *             information.  Normally this will be thrown away.
