libghc-criterion-prof 1.1.0.0-2build3 (amd64 binary) in ubuntu wily

 This library provides a powerful but simple way to measure the performance of
 Haskell code. It provides both a framework for executing and analysing
 benchmarks and a set of driver functions that makes it easy to build and run
 benchmarks, and to analyse their results.
 .
 The fastest way to get started is to read the documentation and examples in
 the Criterion.Main module.
 .
 This package provides a library for the Haskell programming language, compiled
 for profiling. See http://www.haskell.org/ for more information on Haskell.
