+/**
+ * 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.
