"""
Creates the initial galaxy database schema using the settings defined in
universe_wsgi.ini.

This script is also wrapped by create_db.sh.

.. note: pass '-c /location/to/your_config.ini' for non-standard ini file
locations.

.. note: if no database_connection is set in universe_wsgi.ini, the default,
sqlite database will be constructed.
    Using the database_file setting in universe_wsgi.ini will create the file
    at the settings location (??)

.. seealso: universe_wsgi.ini, specifically the settings: database_connection
and database file
