/* 
 * Logging levels from syslog.h
 *
 * priorities/facilities are encoded into a single 32-bit quantity, where the
 * bottom 3 bits are the priority (0-7) and the top 28 bits are the facility
 * (0-big number).  Both the priorities and the facilities map roughly
 * one-to-one to strings in the syslogd(8) source code.  This mapping is
 * included in this file.
 *
 * priorities (these are ordered)
 *
 * LOG_EMERG	0	// system is unusable
 * LOG_ALERT	1	// action must be taken immediately
 * LOG_CRIT		2	// critical conditions
 * LOG_ERR		3	// error conditions
 * LOG_WARNING	4	// warning conditions
 * LOG_NOTICE	5	// normal but significant condition
 * LOG_INFO		6	// informational
 * LOG_DEBUG	7	// debug-level messages
