Import parsec-3.1.5 as textproc/hs-parsec,
packaged for wip by pho.

Parsec is designed from scratch as an industrial-strength parser
library. It is simple, safe, well documented (on the package
homepage), 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.
