Hi Manuel,

Here's how I setup my logger:

> boost::log::register_simple_formatter_factory<
> boost::log::trivial::severity_level, char >("Severity");
>    
> boost::log::add_file_log(
>     fileName,
>     keywords::auto_flush = true,
>     keywords::format = "[%TimeStamp%] - %Severity%: %Message%"
> );

I needed to set the `keywords::auto_flush = true` parameter to true to
get auto flush to work.  I'm using Boost log 1.55 in linux with gcc and
windows with Visual Studio 2013.

I never tried setting the boost properties from a settings file, so I'm
not sure about issues with that.

Hope that helps!

Cheers

Ps: If you'd like to see the full source code of my logger, you can see
