-    This is a convenient middleware to inspect what's passing through the
-    downloader middleware. It logs all requests and responses catched by the
-    middleware component methods. This middleware does not use any settings and
-    does not come enabled by default. Instead, it's meant to be inserted at the
-    point of the middleware that you want to inspect.
