     "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 also includes an executable which
type-checks a Dhall file and reduces the file to a fully evaluated normal
form.")
