I hope the log will end up in Emacs buffers, or at least that there
will be an option to do so.  While other logging frameworks are
designed to work with programs that leave log files, in Emacs it is
customary to have the log in a buffer (and then the user can save that
buffer if needed).  Direct writes of debug info to files is rare in
Emacs (see open-dribble-file and open-termscript as about the only
examples I'm aware of).
