Module documentation for 2.2.0.0

This library uses GHC.Generics to derive efficient optics (traversals, lenses and prisms) for algebraic data types in a type-directed way, with a focus on good type inference and error messages when possible.

The library exposes an optics interface. For a van Laarhoven interface, see generic-lens.
