I really like that Boost::Log also provides an option to replace 
old log files (instead of creating new ones) when disk capacity 
reaches a certain threshold.  It might also be worth providing an 
option to simply limit the max log file count to N, which then 
replaces oldest first.  In some unexpected situations I've seen 
the disk fill from a badly behaved program, and these are a nice 
safeguard.
