Fltkhs - A Haskell Binding to the FLTK GUI Library

Fltkhs aims to be a complete Haskell binding to the [FLTK GUI library] 1.

NOTE: As of version 0.5.0.1 only FLTK 1.3.4-1 is supported. Old code written against FLTK 1.3.3 will still work, 1.3.4 does not remove any functionality.

NOTE: As of version 0.4.0.0, due to the introduction of closed type families, only GHC >= 7.8.1 is supported.
