This is a little output test suit for Haddock. To add a test: 1 Create a module in the "tests" directory 2 Run runtests.hs (giving it the lib dir to GHC). You should now have output/.html but the test will always pass since there is no reference output to compare with 3 To add reference output, do runhaskell copy.hs You can also do runhaskell copy.hs to copy all output into reference files
