% logging levels explained:
%
%   FATAL: indicates the system has failed and can not continue
%   ERROR: indicates a subsystem has failed but the failure is not fatal
%   WARN:  indicates an unexpected occurance was found in a subsystem
%   INFO:  indicates a subsystem has changed state
%   DEBUG: reports subsystem data that should be useful for debugging
%   TRACE: reports subsystem data that is only for tracing execution

% Logging output will log asynchronously until the logger's
% message queue becomes too large, then use synchronous logging
% while the message queue remains large
