Re: [boost] Boost Logging library - first draft

I havent had a chance to look at your code or pantheios yet but I am 
interested in your library.
A boost library would be something to standardize on for larger projects.
One facility I like to have however is the ability to output to the 
debugger. Does yours do this or do you intend to add it ?
Its not always feasible to do this for performance reasons though so you 
need to be able to toggle it off and on of course(Full screen games are 
my biggest culprit there).
I have a very simple library I wrote myself to allow this but it is 
lacking some features as well.
It seems everyone has their own homegrown solution to this.

TIA
