Setup
-----
.. code:: bash

    cp at.cfg.dist at.dist

    # edit config file using your favourite editor
    $EDITOR at.cfg

    # create new database file (or copy existing one)
    sqlite3 at.db < dbsetup.sql

    # create python virtual environment
    python3 -m venv vevnv
    ./venv/bin/python3 -m pip install -r requirements
    ./venv/bin/python3 -m pip install gunicorn

Running
-------
.. code:: bash

   ./venv/bin/gunicorn run:app

When running on OpenBSD make sure to pass '--no-sendfile' argument to gunicorn
command. This will prevent AttributeError on os.sendfile that seems to be
missing in this marvelous OS-es python3 stdlib.
