This module provides a simple WSGI profiler middleware for finding 
bottlenecks in web application. It uses the profile or cProfile 
module to do the profiling and writes the stats to the stream provided

To use, run `flask_profiler.py` instead of `app.py`

see: http://werkzeug.pocoo.org/docs/0.9/contrib/profiler/

# this is a config sample for log normalization, but can
# be used as a more complex general sample.
# It is based on a plain standard rsyslog.conf for Red Hat systems.
# 
# NOTE: Absolute path names for modules are used in this config
# so that we can run a different rsyslog version alongside the
# regular system-installed rsyslogd. Remove these path names
# for production environment.
