95 Higher log level numbers imply the most verbosity (expect higher tracing
96 throughput). Log levels 0 through 6 and log level 14 match
97 <a href="http://man7.org/linux/man-pages/man3/syslog.3.html" class="ext">syslog</a>
98 level semantics. Log levels 7 through 13 offer more fine-grained
99 selection of debug information.
