#By default the multi-process version of the runtime is launched via the Gunicorn webserver and is configured to use gevent-based concurrency and a number of processes equal to the number of CPU cores available.

#This can be changed by creating a file called gunicorn.conf.py in your applications root directory, which will override the default gunicorn.conf.py included with this project

# package. 'gevent' or other workers would be candidates, except that the ndb
# library has its own concurrency model that conflicts with gevent and possibly
# with similar approaches.
