I have not been able to devote enough time to make a full length review.
So this is more of a feeling than of a review. Fell free to ignome my
vote accordingly.
> * What is your evaluation of the design?
It seems to be a little bit too raw to be usable by the unwary user.
Some eviewers have complained about the use of macro. Loggoing is IMO
one of the few places where macro usage is a good thing. There are some
places where logging won't get acceptance if it cannot be demonstrated
the it can be zero cost when de-activated (even if all odds are that it
will finally not be de-activated). It is a psychological problem as well
as a technical problem, but it is important.
> * What is your evaluation of the implementation?
I did not look at the implementation.
> * What is your evaluation of the documentation?
The learning curve is too steep. Is it the fault of the documentation or
of the library ? I do not know.

Not that version. I use previous version successfully with visual C++,
but this version sees to be so much appart that I do not know if this is
relevant at all.

Only read the doc, about 1h spent

Only as well as any programmer should be.

I would like to agree with other reviewers: Logging is so vast a project
that anyone want it own special options that fit its particular needs. I
think the review of the previous version of the library suffered the
same problem. This has led John Torjo to write the swiss army knife of
logging, and still, some people miss miss some options... My opinion is
that a logging library is so much needed that I do not really care if it
is not perfect, as long as it is usable & extendable.

What I miss most is simplicity. I would really appreciate is a basig
logging configuration was provided for a quickstart. By basic, I mean
something that allow code such a this :
- Log onto a file
- Set the log level (at compile time or at run time)
- Log using iostream syntax
- Initialization should be a one-liner in user code.
It can allow more, but the one-liner stuff is important.

I don't knows if there if a fast track second chance review process for
a library. If there is one, I think it would be better to wait a few
weeks and have another review. Otherwise, I vote yes, knowing this
library will probably evolve anyway after the many remarks done during
the review.
