Reading the documentation about CLI, that you can find here (https://phalcon-php-framework-documentation.readthedocs.org/en/latest/reference/cli.html), I don't understand how to create a command line application. A script that I can make executable and run from the command line. I'm trying to create a command line application that takes a single parameter of an application name, then access the app's cache directory to clear the content. Using bootstraps PhalconPHP environment. How can this be done?
