"""
Example of serving an Application using the `aiohttp.web` CLI.

Serve this app using::

    $ python -m aiohttp.web -H localhost -P 8080 --repeat 10 cli_app:init \
    > "Hello World"

Here ``--repeat`` & ``"Hello World"`` are application specific command-line
arguments. `aiohttp.web` only parses & consumes the command-line arguments it
needs (i.e. ``-H``, ``-P`` & ``entry-func``) and passes on any additional
arguments to the `cli_app:init` function for processing.
