[Haskell-beginners] some cabal file values

I was getting reading to upload a module to hackage. I did that once before a long time ago, so I reused and modified an old .cabal file. Current there are two copied-in values that I am not sure about: Cabal-version: >=1.2 Build-depends: base >= 4 && < 5 What should these values be set to? code: -------- $ cabal --version cabal-install version 0.10.2 using version 1.10.2.0 of the Cabal library $ ghc --version The Glorious Glasgow Haskell Compilation System, version 7.4.1 -------- -- frigidcode.com indicium.us
