+# Server socket
+#
+#   bind - The socket to bind.
+#
+#       A string of the form: 'HOST', 'HOST:PORT', 'unix:PATH'.
+#       An IP is a valid HOST.
+#
+#   backlog - The number of pending connections. This refers
+#       to the number of clients that can be waiting to be
+#       served. Exceeding this number results in the client
+#       getting an error when attempting to connect. It should
+#       only affect servers under significant load.
+#
+#       Must be a positive integer. Generally set in the 64-2048
+#       range.

+#
+# Worker processes
+#
+#   workers - The number of worker processes that this server
+#       should keep alive for handling requests.
+#
+#       A positive integer generally in the 2-4 x $(NUM_CORES)
+#       range. You'll want to vary this a bit to find the best
+#       for your particular application's work load.
+#
+#   worker_class - The type of workers to use. The default
+#       async class should handle most 'normal' types of work
+#       loads. You'll want to read http://gunicorn/deployment.hml
+#       for information on when you might want to choose one
+#       of the other worker classes.
+#
+#       An string referring to a 'gunicorn.workers' entry point
+#       or a python path to a subclass of
+#       gunicorn.workers.base.Worker. The default provided values
+#       are:
+#
+#           egg:gunicorn#sync
+#           egg:gunicorn#eventlet   - Requires eventlet >= 0.9.7
+#           egg:gunicorn#gevent     - Requires gevent >= 0.12.2 (?)
+#           egg:gunicorn#tornado    - Requires tornado >= 0.2
+#
+#   worker_connections - For the eventlet and gevent worker classes
+#       this limits the maximum number of simultaneous clients that
+#       a single process can handle.
+#
+#       A positive integer generally set to around 1000.
+#
+#   timeout - If a worker does not notify the master process in this
+#       number of seconds it is killed and a new worker is spawned
+#       to replace it.
+#
+#       Generally set to thirty seconds. Only set this noticeably
+#       higher if you're sure of the repercussions for sync workers.
+#       For the non sync workers it just means that the worker
+#       process is still communicating and is not tied to the length
+#       of time required to handle a single request.
+#
+#   keepalive - The number of seconds to wait for the next request
+#       on a Keep-Alive HTTP connection.
+#
+#       A positive integer. Generally set in the 1-5 seconds range.

+# Debugging
+#
+#   debug - Turn on debugging in the server. This limits the number of
+#       worker processes to 1 and changes some error handling that's
+#       sent to clients.
+#
+#       True or False
+#
+#   spew - Install a trace function that spews every line of Python
+#       that is executed when running the server. This is the

+#
+#       A valid user id (as an integer) or the name of a user that

+#       A valid value for the os.umask(mode) call or a string
+#       compatible with int(value, 0) (0 means Python guesses

+#
+#   tmp_upload_dir - A directory to store temporary request data when
+#       requests are read. This will most likely be disappearing soon.

+#       table. This affects things like 'ps' and 'top'. If you're
+#       going to be running more than one instance of Gunicorn you'll
+#       probably want to set a name to tell them apart. This requires
