/**
 * ArgvInput represents an input coming from the CLI arguments.
 *
 * Usage:
 *
 *     $input = new ArgvInput();
 *
 * By default, the `$_SERVER['argv']` array is used for the input values.
 *
 * This can be overridden by explicitly passing the input values in the constructor:
 *
 *     $input = new ArgvInput($_SERVER['argv']);
 *
 * If you pass it yourself, don't forget that the first element of the array
 * is the name of the running application.
 *
 * When passing an argument to the constructor, be sure that it respects
 * the same rules as the argv one. It's almost always better to use the
 * `StringInput` when you want to provide your own input.
