Re: [Cppcms-users] booster::log

so if i guess it right:
  - a level is not sink specific, it's dependent on the message that 
should be logged.
  - a sink is the backend of the logger
  - every message goes to the logger and then to every sink.

My idea is to implement a sink specifiec logger level, that means you 
register a sink
   l.add_sink(fsink, debug);
   l.add_sink(csink, error);

with the error level.
What does it mean:
     The responsibolity of logging is not in the message itself but in 
the registered sink.
     You don't have to check if the message itself should be logged, but 
if a sink is registered that has this loglevel (or above of course)

You also may specific a name, instead of a pointer for a registered 
sink, f.e.

   fsink.name("fileLogger");
   csink.name("ConsoleLogger");

My inspiration is the logger util from java which I really like. 
http://docs.oracle.com/javase/1.4.2/docs/api/java/util/logging/Logger.html
The hirachy is optional but I like the concept.
