Here's the code. You can see it's short and simple; half the code is
just to make it more configurable. Usage:
pyramid_includes = accesslog
# Settings, all optional
access.format = {response.status_int} {request.method} {request.path_qs}
access.ignore = /fanstatic /_debug_toolbar
access.ignore_usual = true
