+/**
+ * Log events to a system log using the PHP syslog() function.
+ *
+ * This appenders requires a layout.
+ *
+ * ## Configurable parameters: ##
+ *
+ * - **ident** - The ident of the syslog message.
+ * - **priority** - The priority for the syslog message (used when overriding
+ *     priority).
+ * - **facility** - The facility for the syslog message
+ * - **overridePriority** - If set to true, the message priority will always
+ *     use the value defined in {@link $priority}, otherwise the priority will
+ *     be determined by the message's log level.
+ * - **option** - The option value for the syslog message.
+ *
+ * Recognised syslog options are:
+ *
+ * - CONS     - if there is an error while sending data to the system logger, write directly to the system console
+ * - NDELAY - open the connection to the logger immediately
+ * - ODELAY - delay opening the connection until the first message is logged (default)
+ * - PERROR - print log message also to standard error
+ * - PID    - include PID with each message
+ *
+ * Multiple options can be set by delimiting them with a pipe character,
+ * e.g.: "CONS|PID|PERROR".
+ *
+ * Recognised syslog priorities are:
+ *
+ * - EMERG
+ * - ALERT
+ * - CRIT
+ * - ERR
+ * - WARNING
+ * - NOTICE
+ * - INFO
+ * - DEBUG
+ *
+ * Levels are mapped as follows:
+ *
+ * - <b>FATAL</b> to LOG_ALERT
+ * - <b>ERROR</b> to LOG_ERR
+ * - <b>WARN</b> to LOG_WARNING
+ * - <b>INFO</b> to LOG_INFO
+ * - <b>DEBUG</b> to LOG_DEBUG
+ * - <b>TRACE</b> to LOG_DEBUG
