Comment:

 I've updated one trivial typo in src/lib/log/logger.h's doxygen, and I saw
 two more but did not know exactly what to make of it; 'disction' on line
 70 (i assume it is supposed to say dictionary, but i'm not sure), and the
 sentence on line 82 does not seem to have been finished (... using.)

 Code itself looks good. I do have one bikesheddy comment, and that may be
 personal preference; I tend to view 'syslog' as one name of a system for
 logging. As such, my CamelCasing would be Syslog, not SysLog.

 And finally, a question; do we think we can make our test shellscripts not
 print the actual log messages themselves? (i've been meaning to make the
 rest of the tests 'disable' logs completely, I really don't want to see
 ERROR and WARN etc unless there is something wrong. Of course we need to
 trigger that said messages are logged, but if possible, I'd like to not
 show them).
