# Library Coq.extraction.ExtrHaskellString

# Special handling of ascii and strings for extraction to Haskell.

Require Coq.extraction.Extraction.
Require Import Ascii.
Require Import String.
Require Import Coq.Strings.Byte.
Require Export ExtrHaskellBasic.

# At the moment, Coq's extraction has no way to add extra import

# statements to the extracted Haskell code. You will have to

# manually add:

*

# import qualified Data.Bits

# import qualified Data.Char
