libghc-quickcheck-text-prof 0.1.2.1-5 (amd64 binary) in ubuntu groovy

 The usual Arbitrary instance for Text (in quickcheck-instances) only
 has single-byte instances and so isn't an ideal representation of a
 valid UTF-8 character. This package has generators for one-, two- and
 three-byte UTF-8 characters (all that are currently in use).
 .
 This package provides a library for the Haskell programming language, compiled
 for profiling. See http://www.haskell.org/ for more information on Haskell.
