Description:
Wadler/Leijen Pretty Printer, with annotation support
This is a modified version of wl-pprint, which was based on Wadler's paper "A Prettier Printer". This version allows the library user to annotate the text with semantic information, which can later be rendered in a variety of ways. . This package provides a library for the Haskell programming language. See http://www.haskell.org/ for more information on Haskell.
