 //! To enable mock configuration of entraited functions, supply the `mock_api` option, e.g. `mock_api=TraitMock` if the name of the trait is `Trait`.
 //! This works the same way for entraited modules, only that those already _have_ a module to export from.

-//! Unimock support is enabled by passing the `unimock` option to entrait (`#[entrait(Foo, unimock)]`), or turning on the `unimock` _feature_, which makes all entraited functions mockable, even in upstream crates.
