Is this what you mean?

Answered on this earlier.

Severity is not special. Users of channel-based logging would argue the 
same way about channels and they would be right.

mc is not present in MinGW, GCC or MSVC Express. You would have to 
install Windows SDK or full MSVC to get it. The mc tool is expected to 
be present in MSVC 10 Express. I have added the note to the docs in 
trunk about that.
