Using Applications
------------------
To use such an application you have to create it in a separate file first,
otherwise the :command:`flask` command won't be able to find it. Here's an
example :file:`exampleapp.py` file that creates such an application::
To run such an application, you can use the :command:`flask` command::
from yourapplication import create_app
app = create_app('/path/to/config.cfg')
It can then be used with the :command:`flask` command::
export FLASK_APP=exampleapp
export FLASK_APP=myapp
flask run
Flask will automatically detect the factory (``create_app`` or ``make_app``)
in ``myapp``. You can also pass arguments to the factory like this::
export FLASK_APP="myapp:create_app('dev')"
flask run
Then the ``create_app`` factory in ``myapp`` is called with the string
``'dev'`` as the argument. See :doc:`/cli` for more detail.
