Hi all, I'm not making a full review, just a feature request, since I'm not having enough time lately to even update to the latest version of the library. But I'm using this library for sometime now(a few months) and it is working okay for me. The feature request I would like to make is: In the version I'm working(and probably the newer one either), it is possible to add appenders with functors/functions with two string parameters. This is a very useful thing since it let the user extend the library to log in differents storages/streams/etc. However, the library assumes that the function it calls operates in a real stream, and buffers based on this assumption, restricting the usefullness and the reuse of the log interface for use on "message-based" storages. The real feature request is that it be possible to tune the library to be able to work in a message-based form, using flush commands (like std::endl) to indicate the end of the message. My use-case for this feature is writing in the Event Logger in Windows 2000/2003/XP. I sent this feature request to John Torjo sometime ago, but didnt got any reply, so I thought in reposting it in the review process. So that, perhaps, more people may be having this need too. If this is already covered in the new version, then I'm sorry for wasting your time. For the rest of the library, tt is very good and, IMO, it should be accepted in boost.
