Yes, exactly.  There's usually a log_info category or something that doesn't
get turned on/off by the level settings, macro expansion, etc.

I haven't had time to look at his code yet :-(

I'm not sure I understand -- are you saying you will integrate new logging
into the same output stream without having to recompile all the existing code?

BTW, one 'logging related' feature I would love to see is the stack snap that
was discussed maybe 2 years back and has some prototypes in the files section.
 It would be wonderful to log a stack trace with data before throwing an
exception.  I realize it wouldn't be portable to all platforms, but it can be
ported 'the major platforms' and it would be a huge boon to solving real-world
problems in big software systems.  Of course it could be a stand-alone lib too...
