Module documentation for 2.2.1.0

Used by 2 packages in nightly-2022-11-30(full list with versions):

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.

This package is the shared internal logic of the generic-lens and generic-optics libraries.
