 This package provides the documentation for a library for the Haskell
 programming language.

 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.
