I just read the entire documentation of your logging library - it sounds  
very good! I didn't write any code and didn't use your library yet but  
will definitely do. So far I've only one question regarding  
BOOST_LOG_DECLARE_GLOBAL_LOGGER. Having read  
http://boost-log.sourceforge.net/libs/log/doc/html/advanced/advanced.html#advanced.advanced.sources.global_storage  
I understand that this macro is used to help developers not to violate the  
ODR. Having read the entire documentation I'm a bit surprised though that  
it's used everywhere by default (like in the tutorial). I would expect  
that by default developers can define a global logger with

src::severity_logger_mt lg;

_unless_ they violate the ODR. _Then_ they can use  
BOOST_LOG_DECLARE_GLOBAL_LOGGER. Either I missed something and I always  
should use BOOST_LOG_DECLARE_GLOBAL_LOGGER or the library author (you :)  
thought that developers too often violate the ODR without noticing and  
better always use the macro even if it isn't really necessary?
