It uses the :mod:`profile` or :mod:`cProfile` module to do the profiling and writes the stats to the stream provided (defaults to stderr). Example usage:: from werkzeug.contrib.profiler import ProfilerMiddleware app = ProfilerMiddleware(app) :copyright: (c) 2014 by the Werkzeug Team, see AUTHORS for more details. :license: BSD, see LICENSE for more details. iÿÿÿÿN(tProfile(tStatst MergeStreamcBs eZdZd„Zd„ZRS(süAn object that redirects `write` calls to multiple streams.

Wraps a WSGI application and profiles a request. This intentionally buffers the response so that timings are more exact. By giving the `profile_dir` argument, pstat.Stats files are saved to that directory, one file per request. Without it, a summary is printed to `stream` instead.
