   The only required argument is the path to the cabal file. For example:
   .
-  > cabal2nix http://hackage.haskell.org/packages/archive/cabal2nix/1.70/cabal2nix.cabal
-  > cabal2nix cabal://cabal2nix-1.70

   .
   If the @--sha256@ option has not been specified, cabal2nix calls
   @nix-prefetch-url@ to determine the hash automatically. This causes
