Indeed so :)

Basically it's in my TODO list. The v2 of the library is *very* 
extensible/flexible, thus docs can go on an on.
So, to answer your question:
- there's no doc yet
- I will provide one after the review

Quick summary:
- On the usage side: BOOST_LOG macro from v1. You'll need to define your 
BOOST_LOG similar to this:

#define BOOST_LOGL(lvl) BOOST_LOG_USE_LOG_IF_LEVEL(g_l(), g_log_level(), 
lvl )

BOOST_DEFINE_LOG_FILTER(g_log_level, boost::logging::level::holder ) // 
holds the application log level
BOOST_DEFINE_LOG(g_l, logger_type) // logger_type - depends on what 
logger you want

- On the initialization :
As you see, this is quite different from v1. Just in case you have 
problems, showing me the initialization code could help.

Best,
John
