cabal-version:  3.0

name:        yaya-quickcheck
version:     0.2.0.1
synopsis:    QuickCheck testing support for the Yaya recursion scheme library.
description: If you use Yaya in your own code and have tests written using
             QuickCheck, then this library will help you with generating trees,
             verifying type class instances, etc.
