While using rotating text file as stream, is it possible to keep most
recent log file name same all the time?  Currently what I observe is 'N'
keeps incrementing and have to manually find out the most recent file. 
 
Also,
is there some way to print severity in log file without explicitly
passing it as part of message i.e. BOOST_LOG_SEV(my_logger, CRITICAL)
 
Thanks
