'''BioThings API ioloop start utilities.

This module contains functions to configure and start the `base event loop <http://www.tornadoweb.org/en/stable/ioloop.html>`_ from command line args.  Command line processing is done using tornado.options, with the following arguments defined:

    * ``port``: the port to start the API on, **default** 8000
    * ``address``: the address to start the API on, **default** 127.0.0.1
    * ``debug``: start the API in debug mode, **default** False
    * ``appdir``: path to API configuration directory, **default**: current working directory

    The **main** function is the boot script for all BioThings API webservers.
