 This library is a binding to the Xft library.

 Xft provides a client-side font API for X applications, making the FreeType
 font rasterizer available to X clients. Fontconfig is used for font
 specification resolution. Where available, the RENDER extension handles glyph
 drawing; otherwise, the core X protocol is used.

 This package provides a library for the Haskell programming language, compiled
 for profiling. See http://www.haskell.org/ for more information on Haskell.
