Thanks, I'll take a look.

Thanks! Your answer has shown me the benefits of such a separating. I
need only to log crashes, so using error_logger:error_report/2 in
conjunction with gen_event callback (for catching all the well-known
errors and writing "user-friendly" logs for admins) seems to be a good
solution for me.
