Boost.Log passed a formal review about a year ago but needs lots
of updates and meanwhile it is not ready.

1. You will still need to write something like

   booster::log::logger::instance().add_skink(booster::shared_ptr<booster::log::sink>(new booster::log::sinks::file(...)));

2. If you are using logger with CppCMS - it can configure it for you
   automatically:

   http://cppcms.com/wikipp/en/page/cppcms_1x_config#logging

3. Yes I can add an option :-), fill a request feature ticket or
   send a patch.

The standard_error sink is defined as simple as that:

 class standard_error : public booster::log::sink { 

 public:

   void standard_error::log(message const &msg)
   {
        std::cerr << format_plain_text_message(msg) << std::endl;
   }
 };

So just write your own sink :-)

This string is module name so you write:

   BOOSTER_WARNING("bank") << "We run out of money";

This is handled automatically by macros for you.

This string is a part of the message object.

Yes, it is true.


Booster is an answer of my needs from Boost that
boost does not allow me to handle properly, that is why Booster
has the same license as Boost.
