The module free-theorems-counterexamples-0.3 can be installed the following way:
runhaskell Setup.hs configure --user
runhaskell Setup.hs build
runhaskell Setup.hs haddock
runhaskell Setup.hs install
runhaskell Setup.hs haddock builds the documentation.
This step is not necessary.
After installation the modules
Language.Haskell.FreeTheorems.Variations.CounterExamples.ExFind
Language.Haskell.FreeTheorems.Variations.CounterExamples.Algorithm.ExFindExtended
Language.Haskell.FreeTheorems.Variations.CounterExamples.Common.AlgCommon
Language.Haskell.FreeTheorems.Variations.CounterExamples.Parser.ParseType
are available.
