-What is the CLI?
-================
-
-The command-line interface is a text-based method of interacting with
-computers. For more information, check the `Wikipedia
-article <https://en.wikipedia.org/wiki/Command-line_interface>`_.

-Why run via the command-line?
-=============================
-
-There are many reasons for running CodeIgniter from the command-line,
-but they are not always obvious.
-
--  Run your cron-jobs without needing to use *wget* or *curl*.
--  Make your cron-jobs inaccessible from being loaded in the URL by
-   checking the return value of :php:func:`is_cli()`.
--  Make interactive "tasks" that can do things like set permissions,
-   prune cache folders, run backups, etc.
--  Integrate with other applications in other languages. For example, a
-   random C++ script could call one command and run code in your models!
