                      4:  *  SYSLOG.H -- declarations for system logging program
                      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.
