+Configuration
+=============
+
+   .. option:: -c <FILE>, --config <FILE>
+
+      Load options from the specified configuration file. Command line
+      options will take precedence over any options specified in the
+      configuration file.
+
+   .. option:: -d, --debug
+
+      Enable debugging output.
+
+   .. option:: --driver <DRIVER>
+
+      Load balancer driver to use. Valid driver options are:
+
+      * *haproxy* - `HAProxy <http://haproxy.1wt.eu>`_ software load balancer.
+        This is the default driver.
+
+   .. option:: -h, --help
+
+      Show the help message and quit.
+
+   .. option:: -n, --nodaemon
+
+      Do not run as a daemon. This option is useful for debugging purposes
+      only as the worker is intended to be run as a daemon normally.
+
+   .. option:: -v, --verbose
+
+      Enable verbose output. Normally, only errors are logged. This enables
+      additional logging, but not as much as the :option:`-d` option.
