21 * priorities/facilities are encoded into a single 32-bit quantity, where the
22 * bottom 3 bits are the priority (0-7) and the top 28 bits are the facility
23 * (0-big number). Both the priorities and the facilities map roughly
24 * one-to-one to strings in the syslogd(8) source code. This mapping is
25 * included in this file.
