 Dhall is an explicitly-typed configuration language that is not Turing
 complete. Despite being Turing-incomplete, Dhall is a real programming
 language with a type-checker and evaluator.
 .
 Use this library to parse, type-check, evaluate, and pretty-print the Dhall
 configuration language.
 .
 This package provides the documentation for a library for the Haskell
 programming language.
