Parsec is designed from scratch as an industrial-strength parser
library. It is simple, safe, well documented, has extensive
libraries and good error messages, and is also fast. It is defined
as a monad transformer that can be stacked on arbitrary monads, and
it is also parametric in the input stream type.
This requires ghc, haskell-transformers, haskell-mtl, haskell-deepseq,
and haskell-text.
