Independently, `resourcet` provides the `Acquire` abstraction, which also performs resource allocation, but also plugs into the `MonadResource` type class. This library provides a way of converting a `Pool` into an `Acquire`, if using `Acquire` functions is easier for your application.++This library exports a single function++```hs+poolToAcquire :: Pool a -> Acquire a+```++which pretty much does what it says on the box.
