 Registers an external type as a member of the program group without modifying its definition.
-The type's simple name is used as the enum variant, just like `pack!` or `#[derive(Groupped)]`.

+## Feature `picker`
+
+**Description:**
+
+Introduces the `arg-picker` dependency, providing more advanced argument parsing capabilities for Mingling.
+
+It can coexist with the `parser` and `clap` features, but it is recommended not to enable it alongside the `parser` feature, as their APIs are very similar.
+
+`picker` is an argument parser independent of Mingling and does not rely on the built-in argument extraction API of `mingling_core`.
+
+See [example](https://mingling-rs.github.io/mingling/docs/example-viewer.html?name=example-argument-picker)
